Chapter 1: Entrance Exam

Chapter Text

My name is Riley Evergreen, and I am a free-use sex toy. It's easily the greatest job in the world, for sure. You get to meet lots of friendly people, get loads of attention, and make people happy every day! There's simply no other way to say it - I'm the luckiest girl-turned-sex-toy alive.

But first, I better explain about the world I live in, and what a free-use sex toy is! See, I'm not just good for a quick blowjob, I happen to know I'm talking to you from a different dimension! Yeah, crazy, right? Our world works a bit different to your (frankly, boring) one. No, I don't know how I'm speaking to you pandimensionally! And don't ask how a seven year old girl like me knows the word pandimensionally either. I'm more than a pretty set of holes, don'tcha know!

In our world, everyone's a woman. Pretty simple, right? About half the population has a penis, and I'm so glad for that because I love dicks. Some women with dicks have more than one, which is even more exciting. Best of all? Everyone loves sex. Our bodies are just built for it - no pesky injuries or sicknesses or anything gross like that. The insides of our bodies are super amazing, and that makes having sex so much more fun!

Now, a free-use sex toy - you can probably guess, like, the obvious parts of it. You're saying, Riley, duh, of course I know what a free-use sex toy does, you just sit there and get fucked day in and day out by whoever wants to use you, and to that I say, rude! I do not just sit there! Being a free-use sex toy is a lot of work, and-- well, I'll get into my training soon. But first, a quick description: A free-use sex toy is a girl who gave up on being treated as a regular human and now exists solely to relieve people however they wish. All of a sex toy's holes can be used freely for sexual gratification or as a toilet, and they make sure everyone who comes to them leaves satisfied. So, there! Yep, I'm not, like, a 'person' or whatever now, but that's okay! I never want to stop being a sex toy, especially not after all the hard work it was to become one! Even when every single one of my holes has been pounded for three days straight and I'm gaping open every which way, I don't for even a second want to stop helping people relieve themselves!

Now, not just anyone can be a sex toy. It's a hard job, and we certainly don't want to force girls into it. It's not just a matter of being willing, only the most dedicated find themselves in the honourable position of relieving everyone's bodies! Come along with me for the ride, and I'll tell you how I became a free-use sex toy.

Picture this. Five year old Riley Evergreen. A little over three foot tall, her bright red hair barely tamed into a mid-back length braid held together with copious pink ribbons. Big green eyes shining as she looks up at the front of her brand new school. Little me (well, slightly smaller me) is wearing her absolute favourite rainbow polka-dot thigh high socks, her big pink sneakers that light up with every step, a back-pack with only the coolest cartoon characters on it (whichever one you're thinking of as the coolest, it's that one). Of course, that's it - we're a world who loves sex, why would we care about nudity? It's not just me standing there with my cute little nipples, cushy round tummy, plush tiny butt and soft pussy lips out, it's every other girl there, and their mothers no less!

But, while all the other girls are marveling over the cool playground, or the bright and colourful displays, or all the other kids, I'm staring right at the center of a gang bang. Sure, I'd seen a fair share of sex toys by that point, and used them too (nothing more convenient than a toilet that cleans you up afterwards!), but today was just a little different. First, the girl getting used was barely a couple years older than me, maybe a year older than I am now, and she was standing (or, really, being held up) in front of a sign that said FREE USE SEX TOY PROGRAM AVAILABLE HERE! Apply Today!

Now, I really do have to stress this. This was probably the first time I ever looked at a sex toy at work seriously. Two woman as old as my mother were spitroasting her as they chatted happily, their daughters playing nearby on the slides. The woman fucking this sex toy's throat had a cock that was as thick as my arm and probably longer, gently holding this girl up under her armpits as she thrust in and out with reckless abandon. The woman on the other end had the girl's lower body twisted slightly sideways to slide both of her cocks neatly one each into the sex toy's pussy and asshole. I distinctly remember the woman having tiny, rapid strokes that barely pulled anything out, but her members must've been huge - I could see at least one of them bulging out the flesh in the sex toy's body right up between her nipples. I saw this and thought, that's crazy! That would feel so crazy inside me! Then? I saw the sex toy's face. She wasn't crying, or struggling or unhappy - instead, she looked alert and focused, bobbing her neck and sliding her tongue around to help this woman in her throat cum as hard as she could! Right then and there, I thought that was the coolest girl ever.

So, when we walked in to the school, of course I begged my mum if I could apply for the program. I was gonna be super cool, just like that girl outside! Of course, my mum didn't quite get my silly five-year-old explanation, but she quietly took me aside and explained exactly what the program meant. If I got in, I would have to spend the rest of my life like that girl, even on the days I didn't want to. That if I got in, they would make me work super hard to prove I wanted it, and that I could do the job. I did not care at all. Right then, you could have told me that I would never get to eat peanut butter sandwiches or eat ice cream or watch Pretty Puff Power Girls ever again, and I would have said to your face, "I want to join the program."

Okay, maybe more like "Buh I wanna! I wanna be like the cool girl habing sex, mummy!"

But you get the idea.

Let me quickly outline how the program works. First, there's exams. Basically to make sure no one tricked you into it, you know exactly what it's all about, that your body can handle the work, that you really wanna do it. That pretty quickly weeds out the girls who were just curious. Then, you're in the trial program for a year while you continue your normal schooling. A little taste of both sides, so you have lots of time to see which you like better and what you want. That gets some more girls, too - girls that think getting fucked in the ass by a woman twice your size isn't as fun as, I dunno, homework and doing nothing on the weekends. A big safety net, to make absolutely sure you want this. Consent is important, you know!

The first examination session was at the end of the first week of school. Another little hurdle - a girl who saw the sign and said "Cool!" might have forgotten by Friday, though I was a ball of energy just waiting for the chance. They had all us girls in the hall, and just about half the girls in the school showed up. A few stuffy adults, some of them sex toys, talked about exactly what it was we were here for, and how we could go away at any time and maybe join the program when we were older. They even showed some pictures of sex toys after some really rough sessions of relieving people - women with their holes gaping wide, covered head to toe in cum and pee, barely able to stand. Even though every single one of those sex toys in the pictures had a sparkle of a smile in their eyes, loads of girls left. When they told us what they would do to us in the examinations, some more girls left. At the end, there was maybe about sixty girls left. Which is still lots! But a lot less than before.

For the actual examining part, I think the trick was a rising intensity of tests. First was a normal physical - height, weight, size of certain body parts. Most of the other girls there with dicks had some rock hard boners, and those were the girls that stayed through most of the tests. I don't have a penis myself, but my pussy must've been flooded. I was so excited that I don't even remember.

After the physical exam, the staff got... well, physical. They told me, "Any time you want me to stop, just say so and you can leave."

Then, they started touching me. The woman doing my exam was a pretty lady around my mum's age, with curly brown hair and big, friendly brown eyes. She had a beautiful, curvy body with heavy breasts and a phenomenal cock - though I'm guessing a little, I think she was around ten inches long, with balls the size of my clenched little fists. When I saw that thing, my heart skipped a beat.

"Don't worry, sweetie, I'm not gonna put this in you if you don't want it." The woman seemed ready to stop at the first sign of trouble, but I just shook my head.

"It looks weally nice. Your penis. I weally like it!"

The lady laughed, thanked me, and promised me that if I was very good and listened to all her instructions, then I would get to play with it as much as I wanted to. I think I started to vibrate with excitement at that point. She ran her dark hands over my pale skin, feeling my arms, then my legs, stroking a hand across my face and neck, running her fingers through my hair. She was so careful not to touch anything delicate, not straight away. Then, without warning, she changed. She stuck a thumb in my mouth and played with my tongue, and brought her own lips down to slurp on one of my nipples. Her other hand squeezed roughly at my butt.

"Tell me any time you wanna stop, okay?" Her voice was muffled a bit with my nipple in her mouth, but I got the idea. I don't think I ever wanted her to stop.

She moved her wet thumb down to my clit and began to toy with it. I'd played with it a bit myself at that point, but nothing compared to an adult's technique. I moaned, loudly, and saw a huge smile on the lady's face. I think she knew I was going to be perfect for the program... or that she was totally going to get to fuck me. Probably a bit of both. Her thumb went from gentle to manic like a switch being thrown, and she teased out my very first assisted orgasm. She barely stopped waiting for my legs to stop shaking before she was shoving a finger deep into my tiny pussy. She stuck a finger from her other hand into her mouth, slid it up into my asshole with only a minimum of teasing, and watched my expression carefully. It was a revelation (yes, I use lots of big words for a kid, shut up! I studied hard, y'know!) of just how much pleasure one person could give another. I knew that my job would be to make other people feel this happy. At that point, I was absolutely sold on it. One hundred and ten percent. I would have even given up my light-up sneakers for just one day being a sex toy for real.

So, when the lady went from one finger to two, to three in each hole, I didn't complain, or even frown - I moaned, the lustiest noise you've ever heard a five year old make, as this grown woman stuffed six fingers inside my otherwise untouched body. Then, as she rocked me with yet another orgasm, the lady licked her fingers clean and moved away to write down some notes on a little laptop to one side.

"I'm going to have sex with your body now," the lady informed me with a super-serious look on her face. "That means I'm going to put my penis inside your body, in lots of different ways. Remember, you can tell me to stop whenever you want, and I'll stop straight away."

I nodded - the only part I heard was penis inside. Five year old Riley was staring straight at that cock.

"Riley, sweetie, did you hear me?"

"Mhm."

"Tell me right away when you want to stop, okay? I'm going to start by using your mouth."

My mouth? Part of me was slightly disappointed - I wanted her to pick me up and start pounding my pussy like I'd seen on TV, or like the cool girl on my first day of school! ... But wait, the cool girl also had a penis inside her mouth, and she was so cool when she sucked on it. I grinned wide and waited for instructions.

"Open your mouth up super wide and stick your tongue out."

"Mkay! Are you gonna cum in my mouth, or in my belly?"

"Weeell," the lady grinned, and playfully sized me up, "I think you're so small that it'll just have to go in your belly. But I'll leave a bit in your mouth for you to taste... um, if you don't stop me. Which you can do whenever."

"I weally wanna taste it." I did exactly what she said. Mouth open as wide as it could go, little tongue sticking out, I stood there in the examination room with my heart absolutely pounding as her shaft grew closer and closer. I felt it on my lips, my mouth opening just a bit wider than I thought it could to accommodate her. I even ran my tongue against it, tasting the taste of another person's body part. I didn't recognise it at the time, but there was just the hint of cum on the tip of her dick - I hadn't been the first girl she had examined today, after all. I slurped it up moments before she pushed past my tongue, her cock sliding into my throat.

The lady held my head on either side, angled so I could look up at her. Inch after inch slid down my throat, and my body shuddered at the odd feeling - so strange, yet so right, I was in love from the very first time.

"This is my favourite part. You like it?"

I gave a muffled mhm! and managed to surprise her - I bobbed my head forward, just like that girl had done the other day, and took another inch of cock down my throat. Seeing that, the lady knew that she didn't need to be careful.

She fucked my throat. Sure, she started off slow by my more-experienced standards, but to first-timer five-year-old Riley, she was fucking my throat. All ten inches of dick slid freely, in and out, over and over, the lady carefully making sure not to smack my nose with her belly as she roughly pulled my head up and down her shaft in time with her hip thrusts. I helped too, leaning in as she pulled my head down, rocking back as she let it go, moving my tongue in time with the rhythm. She probably said something like, "You're the best five year old dick-sucker I've ever met, Riley Evergreen!" but that might have been me remembering it wrong. She definitely said I was a natural. Which is true, I am amazing.

My first proper taste of cum was all it took to have me addicted for life. When she finally came, she blasted several warm loads down my throat, then just as she promised she pulled the tip of her cock back in time to deposit the last of it right onto my tongue. I slurped up every last drop, licked the tip of her dick clean, and probably asked her if I could have some more.

"Don't worry, kid. There's plenty more where that came from, as long as you want it."

I don't know what she had going on, either some special medicine or a body enhancement, but my examiner didn't soften up after cumming down a five year old's throat. If anything, her dick was harder than ever, still glistening with spit from my throat as she turned and tapped on her computer keyboard.

"If you're ready for more, hop up onto that bed. We're only a couple of holes away from finishing the standard examination - think you're up for it?"

"Mhm!" Of course I was ready for it. I was going to be Riley Evergreen, Best Sex Toy Ever. I was going to take on whatever this lady dished out. So, I kicked off my shoes, crawled onto the bed on the side of the room, and laid there on my back. I wasn't 100% sure what she was going to do next, but my pussy knew, aching for her cock. The lady didn't take long to oblige.

She crawled onto the bed, straddling my legs and rubbing the tip of her dick against my pussy lips. "I'm gonna put it in here next, okay Riley?"

"Like my mummies do sometimes! Or my sister and her friends!"

"Yeah, just like that! If it feels bad in any way, you tell me to stop straight away. Riley, listening?"

"Hm?" I was not listening. I was staring at her cock, and shuffling my hips closer to rub my clit against the head of her dick. The examiner just chuckled, sighed, and lined herself up. One hand on my hip, the other on her cock, she shoved all ten inches inside my virgin pussy in one go.

I came instantly. The strongest orgasm I'd ever had - though it was a low bar, to be honest - and all she had done was put her dick inside. My body had accepted her all the way inside my womb, and a big bulge in my belly showed where the head of her cock was. She stopped for a moment, started to ask me once again if I wanted to stop, and seemingly thought better of it. Without further ado, we had sex.

First, a relatively tame missionary position. With my legs spread wide by her hips, I sat there in unending bliss as her cock slid in and out of me. I watched mesmerised as her boobs swayed with the rhythm of her penetration, shuddered as I felt the head of her cock scrape just near the entrance on her back stroke before slamming deep inside again. After a bit of time she changed position, with her kneeling and my hips held up level for her to pound. Like this the bulge in my belly was even more pronounced, and I ran my hands all over it as she fucked me.

After a few minutes and a few more of my own orgasms, she flipped me over. The examiner leaned over me again, my head now stuffed between her breasts as she gripped me by the side. Then, she leaned back and held me up, lifted me off the bed as she tucked my legs into her grip, now properly fucking me like a sex toy.

"You like that, Riley?" Her voice was a husky moan, on the cusp of ejaculating.

"Yes! Yeah! M-More!"

Meanwhile, I was a kid on a fun new theme park ride, screaming in joy as I was taken on the ride of my life. With a loud grunt, she slammed me down to the base of her cock and began to cum, pouring her hot seed deep into my tiny womb. My already pudgy belly took on a bit more roundness, and my legs quivered with orgasm. I lost control of my bladder too, warm pee staining the sheets of the examination bed.

"A-Ah, s-sorry, I'm peeing..." I knew it was bad to make a mess, but couldn't stop.

"Heh, that's okay, we can change the sheets." The examiner stroked my head as I relieved myself, her cock still rock hard inside me. When I was done she hopped up, holding me under one armpit. My weight was split between that one hand grip and her cock, and I felt so comfortable there - wished I could be carried around on a big dick for the rest of my life. With her other hand she pressed a button on the wall. Like magic, the bed vanished into a nook in the wall, made a loud whirring noise, and came out completely clean.

I actually clapped. So embarrassing.

"Pretty cool, huh? Even if we make a huge mess, there's no problem. Speaking of which, you ready for me to stick it in your backside?"

I looked up at her and smiled. "Pound my butt until I'm spitting up cum!"

"Wow, where'd you hear something like that?" She lifted me off her cock and placed me down on the newly clean bed.

"In a movie mummy was watching. It was a bowing one, but I wiked that bit."

The examiner just laughed and shook her head again. Straddling me once again, she lifted up my hips and brought my asshole to rest on the tip of her dick.

"Now, this one will feel a bit different, so--"

"I don't wanna stop! Put it in, pwease!"

She didn't object. In fact, she decided that I could take it even if she was a bit rough. Lubricated with my spit and pussy juices, her thick shaft slid right up my asshole with ease. She lifted me up and shuffled around, leaning her back against the wall so I was sitting in her lap, then, she went to town on me. Each thrust was a full-length lift up and a slam back down that knocked the wind out of me, going faster and faster until she reached an almost manic pace. My whole world became a blur as she fucked my asshole, but I was still awake enough to grab at her breasts and suck one of her nipples, moaning loudly into it as I played with those pillowy mounds. I wasn't sure how many times I came, but I think my examiner got a little carried away - though she was meant to stop on her first orgasm, she continued for a few more minutes of anal ravaging until she hit another. Guess it wasn't every day you got to absolutely pound a five year old girl's asshole.

After her second cumshot, I think she was about to start fucking me again, right then and there, when a concerned face poked in through the door.

"Everything alright, Lacy?" Oh, right, her name was Lacy. How'd I forget that? The woman looking in the door was maybe a bit older than my mum, but she looked a little amused to see how we were arranged.

"O-Oh, yeah, everything's fine! ... Ah, crap, has it been that long already? Where does the time go, eh Riley?"

"Mmm... feels good..."

Lacy and her fellow examiner chatted for a few moments. Something about how she was going to start me on the advanced part of the examination - I wasn't listening, just grinding my hips into Lacy's still rock-hard dick. I could feel her cum inside my asshole, feel it sloshing about in my belly.

"I'll divert your next few to my room - I can tell you're going to need a bit. Good luck, sweetie!"

That last one was aimed at me. She gave me a little wave, and I waved back from my comfy spot between Lacy's breasts.

"Can you fuck me too?"

The other examiner looked a bit surprised. Lacy gave a shrug.

"You can try group sex another time, okay kid?" Lacy lifted me up off her cock, a small flood of cum following onto the sheets. "For now, I have to set up some stuff for the advanced part of the exam. That means you're in the program already, yeah? But we're gonna see if you're in the advanced program."

The other lady left, and Lacy returned to her laptop. She retrieved a bottle and took a long sip from it. I licked my lips, a bit thirsty myself, but Lacy just shook her head.

"This is special medicine, helps me keep this thing going." I didn't need her gesture to remind me to look at that beautiful dick, still hard even after cumming inside me four times. "I've got something else for you to drink while I freshen up. Here, drink this, then tell me which one of these two you like the best."

Lacy grabbed a tiny medicine cup and two small juice boxes from one corner of her desk. Both of the boxes had their labels covered up, so I couldn't tell them apart. I didn't even question that I would just have to taste them to figure out which was better. After I drank the bit of medicine, I went for the juice boxes.

The first one tasted a little bit like apple juice, but with a spiced warmth that made me feel extra energetic. My first tentative sip turned into a greedy slurp, and I downed the contents of the juice box in record time. Lacy just chuckled.

"You were meant to try a little of both and tell me what you thought, but that's okay. Did you like that one?"

I nodded super hard. "It was soo super tasty!"

"Hehehe. Try the other one, Riley."

I gave her the empty juice box and took the second one. When I took a sip I was a little surprised - I had expected more juice like the other one, but this one was thick like a milk drink. It had a taste like super rich chocolate cake, the sweetest candy I had ever tasted. To no one's surprise but Lacy's, I chugged that one down too. Didn't even stop for a breath until it was done.

"Weally, weally, weally yummy!"

"Wow, you liked it that much, huh? Which one was your favourite?"

For the first time that examination, my brain properly stalled out. They were both so good! How could I possibly pick which one? I think I must've made a super serious face, because Lacy laughed and told me it was okay.

"You don't really need to pick one, I was just curious. Do you want to know what was in them?"

I nodded. Lacy smirked.

"Well, this one here," she tapped the first juice box with the tip of her finger, "Was apple juice. But, it had an extra special ingredient in it - my urine."

I didn't know what that was, so Lacy clarified. "Your pee?! ... Wow ... I didn't know pee was so super tasty."

"Do you wanna guess what was in the other one, then?" Lacy put her finger on top of the second juice box. "It was milk, mixed with..."

I gasped. "Your... your poo! I tasted your poo and it was weally yummy!"

"That's right, Riley! Clever girl!"

I was shocked. Amazed, even! All this time, pee and poo had actually been super yummy and nutritious?

Lacy quickly explained. "Now, that medicine I gave you changed your insides just a little bit. It's normally fine if people have a little bit to taste, but sometimes it can make you sick if you have way too much. That medicine made it so you can have as much as you like! And, if you never want to have any again, that's fine too. But, it didn't change your sense of taste - it really is just that yummy!"

That explained so much, my five year old brain decided. Of course people wouldn't eat poop and drink pee if it made you sick, even if it was super yummy. But now I could have all I wanted! I looked at Lacy's penis and licked my lips - I had a feeling what was coming next.

"Now that you've had a sample, and I know that you enjoy the taste - not everyone does! - we can test how ready you are to perform one of the most important roles of a free-use sex toy." Lacy stood up and walked closer to me, her penis an inch from my mouth. I opened my mouth instinctively, and Lacy smiled in approval. "That is, how good you are as a toilet."

Instead of cramming her cock all the way down my throat again (even though I really wanted her to), Lacy rested the tip of her dick on my tongue. I licked at it, eager to taste what was going to come out. Lacy reached back to the desk and had another sip of her special drink, a big one this time.

"Okay, Riley. I'm going to use you as a toilet now. Once I start, it will be really hard for me to stop, but if you don't want any more than just take your mouth away, okay?"

Once again, didn't care. Wanted to drink that pee. Thankfully, Lacy knew by now. She started to pee.

It was a little surprising at first, like I'd just stuck my mouth over a tap. My mouth filled up really quickly, her pee warm and delicious but threatening to overflow. I didn't want to waste a single drop, so I swallowed it. Then, when my mouth got close to overflowing again, I swallowed again. I got into a good rhythm - fill my mouth up, swallow it down, enjoy the warmth on my tongue again. Then, halfway through, Lacy pulled me forward and slid her shaft down my throat. She peed directly into my belly for a minute straight. I was a little annoyed that I couldn't have it poured onto my tongue, but I was content to feel that warmth fill my stomach. When she pulled out of my mouth, I gave a little burp.

"Wow, normally girls spill a bit the first time - you sure you didn't practice before coming here?" Lacy teased me, tapping me on the nose with a finger, then again with the tip of her dick. I reached up and licked it, and nearly got it into my mouth to start sucking clean before Lacy stopped me. "Sheesh you're eager. Well, one last test and I have to let you go. You ready, Riley?"

One more test could only mean ...

Lacy turned around and bent over against her desk. She placed her desk chair right behind her butt and told me to sit in it - the moment I did, I was face to face with her beautiful round asshole. I could see her pussy too, glistening and wet, though I resisted the urge to lick and play with it - mummy always taught me to ask first before touching people. Reaching a hand back, Lacy pulled the chair forward until my nose was pressed right up against her anus. I could smell that chocolate-cake richness already. This time I didn't resist the urge - I pressed my lips to her asshole and stuck my tongue in.

Lacy gasped a little. "Hey-hey, slow down, kid! Alright, I'm gonna poop into your mouth now, same deal as before. Oh, doubt you're gonna need to eat dinner after this one..."

I felt rather than saw her asshole open up, a warm presence sliding out to greet my tongue. I tasted that rich chocolate goodness, but it came in the thick consistency of pudding. Without thinking I chewed off a small bite, swallowed it, and gasped in pleasure at is amazing warmth. However, Lacy's shit was coming out far faster than I could eat it at that rate. I pressed my lips back around her asshole, opened my mouth wide and simply let it slide over my tongue. Moving in little starts and stops, Lacy's poop slid down my throat with the same ease as her cock did, made somewhat easier by the amazing taste and its squishiness. One long unbroken log of poop traveled out of Lacy's anus and down my throat, coming to a stop in my belly alongside my lunch, three doses of cum and a half gallon of piss.

It wasn't the first log, and it wasn't the last.

Another one followed soon after, a little smaller but far warmer than the last one. Then, the last one was softer, richer again. When Lacy's asshole stopped pushing it down my throat for me, I was left with my throat and mouth filled with shit. I swallowed hard, pushing most if it down, savouring the last of the richest part of her poop in my mouth. I ran my tongue all over it, pushed it around inside my mouth, and quivered with joy. It really was the tastiest thing I had ever eaten.

"Fank youmm..." I murmured out around my mouthful, unwilling to finally swallow it. Eventually it fell apart and I was forced to swallow it down, but I enjoyed every last moment of my first experience as a toilet.

"One last thing, clean me with-- ah!"

I hadn't listened to what Lacy was saying, too eager to wipe up the last little bits of shit around her asshole with my tongue. But, I realised after a moment, she was telling me to do it anyways! Obviously because I'm the best toilet there is. Lacy laughed in delight as I wiped her poophole clean, and gently pulled me away before I got too excited eating her ass.

Sitting me back down on my chair, Lacy got me to put my shoes back on and grab my bag. She was already back to tapping away on her laptop, printing out something with an enormous smile on her face.

"Riley Evergreen, I've never seen a girl fly through the exam so eagerly. I really think you'll enjoy the free-use sex toy program, and I can't wait to use you when you're a qualified sex toy!"

Lacy handed me the piece of paper and knelt down to my level. She ran a hand over my body one more time, stopping her thumb just below my clit.

"Next time, you'll get to do even more fun stuff, like use this hole here."

Her thumb sunk in unexpectedly, pushing into a hole I hadn't actually realised I had there. I squirmed and let out a moan - that hole felt great too! Lacy pulled her thumb back, gave it a lick, and smirked.

She sent me out with the instruction to make sure my parents saw the piece of paper in my hand, but I nearly forgot all about it as I realised I might not see her again.

"Thank you for evewyfing!"

I turned and gave her a hug - a hug that coincided with me taking her cock down my throat one last time, right there in sight of everyone in the room beyond. Parents, hopeful applicants to the program, other examiners, my own mum who had patiently waited for me the whole time. I slurped on her cock for as long as Lacy let me, the woman reluctantly pulling back.

"Looks like you certainly had a lot of fun, Riley!" My mum scooped me up into her arms and I hugged her tight.

"Mhm!"

"Well, tell me all about it on the way home-- what's this paper?"

As we were walking out of the building, me holding onto my mum, she read it quietly under her breath. My dear mummy gave a soft laugh.

"What's it say, mummy?"

"It says you have some homework, Riley. You're about to become a very popular girl, I think."

Chapter 2: Homework

Summary:

Who would've thought that the Free-Use Sex Toy Program, with its rigorous entrance requirements, would have had homework? Well, certainly not five-year-old Riley Evergreen. Seven-year-old Riley Evergreen is well aware, however (that's me!) and is waiting to tell you all about it. That, and the program itself! Still a long way to go until I'm actually, for real, a proper Free-Use Sex Toy! Bet you can't wait until I am, huh? Just wait a li'l bit longer!

Chapter Text

So, homework. Most people loathe it. I mean, I know what regular school homework is like - I still had to attend regular school for a whole year, on top of my time in the program! Let me tell you, that homework sucks. But the homework from the Free-Use Sex Toy Program? Now that was loads of fun.

On the car ride home from the examination, I told my mum absolutely everything that happened in that room. My descriptions were perhaps not so eloquent, but no less emphatic - at the time, I thought my mummy was being very quiet to listen carefully to all the things I was saying. In retrospect, her determined fixation on the road and lack of response was due to the fact that she did not want to crash the car while pondering all the things she wanted to do to her sweet little daughter at that very moment.

What I do remember of that car ride home was how I really looked at my mum properly for the first time. Before that point, I just saw my mum. The lady who buys me nice things, gives me big cuddles and cleans me and feeds me and all that sort of stuff. Now, I saw a woman.

First, a slight tangent. As mentioned before, in our world there are no men - just women, about half of whom have penises! Well, we do have more than one way to say 'mum', but they don't really translate nicely, so for now I'll be clear on exactly which mum I'm talking about. This, my Mummy, was the one who carried me in her womb. Her name is Gloria Evergreen. My Mama, the one who 'fathered' me, is ... well, we'll meet Mama later! Back to telling you how hot my mummy is.

Mummy is not very tall, maybe a little bit over five feet. Frizzy red hair like mine, even a matching braid, though mummy doesn't keep hers with pink ribbons. There's absolutely no doubt that mummy is my mummy, seeing as I take after her so much. She is very curvy - wide hips, breasts as big as my head, a big soft butt and squishable thighs that made for a great seat. Even better, she had a penis. A little under a foot long, it was slightly thinner than the one I had taken my first time. That foot long member stood perfectly to painful, twitching attention every time I described how it felt when Lacy fucked me, tiny beads of pre trickling down its length. If my mums hadn't taught me the valuable lesson of 'do not bother the driver', I might have just licked them up.

We arrived home in one piece, mummy shuffling me into the house with that piece of paper clenched tightly in her hand. Our house was a nice, neat standard model of suburbia, enough room for everyone and guests, a nice little garden out the front and some space to run around in the back. Though I highly doubt you care about how nice my house was! I kicked off my shoes at the front door, raced into the lounge room and left my bag on the couch. Normally mummy would tell me to put it away properly, but I think she was a bit distracted, reading over the note in her hand one more time.

"What's it say, mummy? Read it to me!" I hugged her thigh, giving her my very best puppy-dog eyes. She gave a little laugh, stroked my hair and read it aloud for me.

"Notice of Acceptance to the Free-Use Sex Toy Advanced Program. Advanced program, Riley! I guess that lady was very impressed."

"Mhm! She even fucked my butt one more time than she needed to!"

"R-Really now... ahem. Due to exceptional performance during the preliminary examination, Riley Evergreen has been placed directly into the advanced program, which skips a lengthy acclimatisation period. As such, Riley will take time out of her school day once a week to attend program activities and lessons starting one week after the examination. Please note that there may occasionally be extracurricular events that will be mandatory for continued program participation."

"Wassat bit mean, mummy?"

"I guess it means sometimes you'll stay after school for extra lessons? Like a little club! Except instead of playing a sport or something, I guess you'll be, well..."

"Habing lotsa sex?"

"Yeah. That."

I giggled. Mummy was being very funny, her dick twitching hard every time I said something lewd. I really wanted to stroke it, kiss it, suck it, have it inside me, but I knew not to touch without permission. I settled for running my hand up and down my mother's inner thigh, which I think made it a lot harder for her to concentrate.

"Finally," Mummy continued, "To ensure your daughter can understand the lifestyle of a free-use sex toy first-hand, as a homework task she will be required to have sex and be used as a toilet daily. It is recommended that the members of your household and guests spend some time treating her as though she were a fully qualified toy. Remember that if your daughter wishes to stop at any time--"

"Blah! Blahh!"

"Riley?"

I was stomping my feet and making silly noises like a five year old. Because I was.

"Awways 'you can stop' over and over! I don't wanna stop, ever! I weally wanna have sex lots, and drink lotsa cum, and pee, and eat all the tasty poop too!"

Mummy put down the piece of paper and lifted me up, sitting me on the kitchen bench.

"Riley, I love you very much. But you are very stubborn. This better not be like when you thought painting was the coolest thing ever and then didn't do anything with all the stuff we got you!"

I shook my head. I did like painting, but only a little bit. Sex was way more fun, more than anything I had ever done ever. All of my other favourite things were just nowhere near as cool!

"Mummy. Fuck me."

I lifted my arms up to be lifted into whatever position my mum wanted me in. She looked at me, stunned for a moment before regaining her composure.

"Fine then, my little sex toy, if that's what you want! Mummy's not going to hold back!"

My own mother, the woman who carried me in her womb, lined me up on the kitchen bench so that the head of her cock was poking just barely between my soaked pussy lips. Grabbing me under the arms, she lifted me forward and slid me down her shaft. Inch after inch of her cock pushed into my womb, a corresponding bulge on my belly travelling upwards as I slipped ever further down. Halfway down my mummy's cock, she pulled me back up and began the process of slowly fucking her way deeper, every thrust of her hips earning her one more inch into my womb as my body molded around her.

My breath came in time with her thrusts, air pushed out of me every time her dick slid inside me. My mother groaned in unrestrained pleasure, my tight little cunt wrapping around her dick harder than any other hole she'd ever fucked before. Most free-use sex toys were at least ten years old, usually older, so the chance to pound my five-year-old pussy was once in a lifetime. Not that my mummy only got to fuck me the one time. You know what I mean!

Once mummy was able to bottom out in me, her pace greatly increased. Her methodical, exploratory thrusts transformed into frantic hip-swings as mummy gripped me tight and went to town on me. I was capable of little more than holding on and enjoying the ride, babbling ridiculous phrases like "Fuck me harder, mummy!" and "More cock, please, more!"

After a few minutes of absolutely pounding my womb, mummy came. I had already had several orgasms by that point, but I was so damned sensitive and eager at that point that it would be easier to point out the times when a cock was inside me and I wasn't in the middle of an orgasm. When mummy came, she did so much harder than Lacy had. My later theory was that Lacy's loads had been limited by the fact that she had to blow one or more in several girls over the period of a couple of hours - my mummy likely hadn't for a few hours, and maybe only once that day. My stomach immediately bloated outwards, and I looked like I was a month pregnant by the time she was done.

However, one orgasm was not enough for mummy. She slid me off her cock, not caring that she was still spraying ropes all over the kitchen floor - or that a flood of white was pouring out of my cunt and all over her - and lifted me up to start making out with me. Her tongue slid into my mouth, playing with mine as her hands mauled at my little ass. One of her fingers slipped inside, stretching my butthole open. She must have felt a bit of cum on her finger tip, because she pulled away from me and looked at the offending finger.

"You said that lady came inside your butt twice? Well, Mummy's gonna have to clean it out."

Mummy flipped me over and bent me over the kitchen bench. My legs dangled off the side, and I looked back at her, curious - she hadn't immediately started fucking me, so I knew something was up. Instead of slamming that lubed-up dick right into my intestines, mummy bent down and ran a tongue over my asshole. You might be thinking, hey, that doesn't sound like something you would do with a free-use sex toy - aren't they meant to be for relieving you, not the other way around? And to that I say, some people love the taste of a little girl's cum-filled asshole! My mummy certainly did, right then. She slid her tongue deep inside my asshole, licking me absolutely clean of all the cum she could reach. Then, her tongue-bath complete, she straightened up and slid her dick inside me.

She pounded me, leaning over on the bench herself. By that point I had found a favourite position - getting fucked from behind while heavy breasts enveloped my head. It was like I was wrapped in a little cocoon of sex, all soft and warm to go with the frantic anal sex. I squirted all over the side of the bench as mummy blew her second load into me, painting the inside of my asshole white with her cum. Unfortunately, mummy was not on whatever crazy medicine Lacy had been on. Her cock was starting to go soft inside me.

"Is that all?" I looked back at her, pleading for more.

"Is that all? You're insatiable, Riley!" My mum laughed. "Well, I said I'd clean out your asshole, so this will have to do."

Deep inside my body, I felt a sudden warmth as my mum gently stroked my head. She was peeing inside me! My own mother was using my asshole as a toilet right after using it as a cumdump, and I loved it. Mummy was loving it too, but it certainly confused the heck out of my sister and her friends as they walked into the room.

"Mum?! What the heck are you doing?"

"Oh shit! Nice!"

"Dude, is that your sister?"

I turned my head lazily over to look, too blissful in my warmth to do much more than give a little wave. My big sis Andrea was my favourite person ever, after my mums, Pretty Puff Sparkle Cyan and maybe the lunch lady who always gave me an extra treat. She was definitely the coolest person I knew, maybe after that sex toy I saw in front of the poster at my school... okay, enough messing around!

Andrea was as tall as my mummy, which was pretty impressive for a 14-year-old. Straight blonde hair and sparkling blue eyes like my other mother (the one not peeing in my ass right now), she had a scrawny body that just refused to put on any muscle or fat. She had a fringe covering one of her eyes and deep black mascara and lipstick on, which I thought made her look so mature (I think she thought so too). She had black fishnet gloves, calf-length black socks with skulls on them, and these huge black leather platform boots that made her look even taller than she already was. Her chest was completely flat, but a fat pair of eight inch cocks swung between her skinny legs as though to make up for it. Also, she looked outraged.

Tangent time! It's not illegal here to have sex with someone as young as me! But it's definitely a bit strange, and even more so to be using your five-year-old daughter's asshole as a toilet on the kitchen bench. So, my sister was mostly upset about that one.

"Hey sweetie - girls! Your sister passed her exam, so now she has homework! I'll tell you all about it in a bit... mm, that's better." Mummy pulled her soft cock out of my ass, along with a small wave of white-tinged pee that splashed all over the floor. "Oops! Well, I've been meaning to try that messy living technique I heard about..."

As mummy helped me down, I looked over my sister's friends. I knew them both, but like before I'd never really looked at them properly until now.

On Andrea's left was Miyuki, though Andrea always called her 'Mimi'. Apparently I came up with the nickname when I was smaller, but I don't remember. Mimi was the short and curvy counterpart to my sister's tall and bony self. Already sporting sizeable breasts for her age, she had a soft, slightly pudgy body and a round cute face framed by straight black hair that reached her waist. Slanted brown eyes and a button nose made her seem friendly and approachable, but in my sister's words, she 'really knows how to rock'. It was maybe a little bit telling for Miyuki's personality that she was the one who saw my mum pissing into my ass and said 'nice!' Completely naked except for sensible sneakers and her backpack, she had a smooth slit nestled between her soft thighs. Right then, I really wanted to lick it.

Opposite her was Shay, who really wanted everyone to call her 'Thrash' for some reason. Shay had short brown hair and an athletic body, though I had no idea how my super lazy sister ended up becoming friends with one of the sportiest people I ever knew. A bit taller than Andrea, when my sister wasn't wearing her crazy platform shoes, she looked just as surprised as anyone else at the sight in the kitchen, though it didn't escape my notice that her cock was starting to harden. I was extra excited about Shay's cock, more than I'd ever been, now that I had a proper appreciation for such things - her dick was nearly two feet long flaccid, and though I hadn't seen her hard I could definitely tell it was big enough to make a proper mess of me.

All three of them were staring at me openly, though Andrea was looking between me and my mother in exasperation.

"Wh-why didn't you tell me! You could've, like, warned me or something!"

"Ah, I'm sorry sweetie. Let me explain..."

And, she did! I stood there in a puddle of my mum's pee and cum, enjoying the feeling between my toes, while mummy told my sister and friends about everything that had happened. Andrea's expression of surprise quickly turned into one of mild confusion, mostly directed at me ( Since when did my little sister become a horny little devil? ), while Miyuki looked overjoyed. Shay's expression didn't change much, but she did get hard. Her dick stood upright against her cheek, taller than her head, and I felt myself getting wetter just looking at it.

"So!" Mummy clapped her hands. "Are you girls staying for dinner?"

"We sure are! I can't wait to help out-- uh, hang out!"

"U-uh, y-yeah, Mrs Evergreen, yep. Staying."

"Huh? I thought you two said you were just stopping by for a bit?" Andrea whirled around, mustering her best look of suspicion. The girls just giggled.

"I'll tell your mothers that you'll be here." Mummy grabbed her phone from her bag and began to compose a message. While she did so, she fixed the three girls with a look.

"Now, like we discussed, it's Riley's homework that she experiences what it's like to be a sex toy, but if she tells you to stop you need to do so straight away!"

"Blaaahhh!!" I yelled super loud, surprising everyone. "You can fuck me aaaaaaaww night if you wanna! 'Cos I'm the bestest sex toy ever! You can fuck my butt, and my mouth, and my pussy, and everywhere! An' I won't say stop, 'cause I love sex! And poop, and pee! I'm the bestest toilet too!"

"... Riley is a bit enthusiastic, so you might need to tell her to stop if she bothers you too much, okay girls?"

Mimi and Shay nodded their heads emphatically, though neither looked like they were going to have a problem with my horny little self. Andrea just rolled her eyes.

"I'll make sure to kick her out if she's getting super annoying. Did you tell mama?"

"... ah, fuck." Mummy swore under her breath and picked up her phone again, having put it down once she was finished with her message. "I'll give her a call. Girls, help yourselves to drinks, snacks ... and Riley."

Mummy wandered off to her room to call my Mama, and Andrea walked over to the fridge to grab some drinks for everyone. I stood there, wide-eyed and vibrating with excitement as Mimi and Shay walked over to me, instead.

The girls brought me back to Andrea's room. Walls covered in band posters, big bed with pitch black pillows, a couple plush toys quietly hidden under the blankets, Andrea's room was the super coolest place in the world. She even had a big TV and loads of games, and when I promised to sit really still she even let me sit in her lap and watch her play them. But I never got to 'hang out' with her friends, let alone have them use me as a sex toy and toilet, so this was turning out to be a very cool day indeed!

Andrea pulled the mini beanbags in from the lounge room after handing her friends their drinks, arranging them around the TV. I watched my sister's bare ass wave around in the air as she retrieved controllers and other game stuff from a cabinet. I hoped I could suck her dicks by the end of the night, but I also really wanted to lick her pussy and asshole. The memory of the taste of Lacy's pee and poop were still fresh in my mind, and I wanted more.

"Hey, Riley, c'mere." Mimi, sitting back in her beanbag, pat a hand on her thigh. I walked over obediently and took a seat in her lap, enjoying the warm feeling of her soft body. I wiggled my back to touch as much skin to skin as possible, and I wiggled my butt instinctively to curl right up in her. Apparently this wasn't what Mimi meant, the girl looking at me somewhat confused, but she warmed up to it and wrapped me in a tight hug. "Andrea, your sister's so cute!"

"So annoying, more like." Andrea turned on the TV and the title screen for Domination Blaze 5 blared to life. This was one of my favourite games to watch - sexy ladies fought each other, and the winner got to have sex with the other one, with lots of super lewd powers that I totally wish I had in real life. "You wanna go first round, Shay?"

"Y-Yeah." Shay was looking at me as Mimi wiggled me around, her dick still rock hard. "Yeah, I'll go first."

I smiled back at Shay, but she just looked a bit nervous, looking away from me to play the game with my sister.

"Alright, and juuust ... up you go!" Miyuki managed to get me just the right way to flip me upside down. She swung my head until it was between her legs, my face directly in front of her pussy. "Did they show you how to eat out yet, Riley?"

"Like going to a westawant?" I tried to look back up at her, but it was kind of hard to. Miyuki had me folded in half, my legs between me and Mimi, with my ass resting on her breasts. "Or... licking?"

"Yeah, licking! Good girl!" Mimi pet my head like I was a cute pet. "Did they show you?"

I shook my head. "Today was just an eggs-ammy-nation."

"... Oh! So you've never done it before! Hehehe, Mimi gets to be your teacher then!" Miyuki leaned her head forward and kissed me on one of my buttcheeks. I giggled at that, and she giggled right back.

"Alright," she started, "You've got to move your tongue all over me, down there, but especially here! You can use your fingers to help too."

Mimi reached down and moved one of my hands to point out her clit, and I dutifully did what I was told. She tasted great - a hint of pee and something else, a feeling I really wanted to soak into my tongue. As I got to it, Miyuki started stroking my butt.

"Andrea, mm, your sister's a natural!"

"Huh? Agh, damn it, stop distracting me!" I heard the loud PLAYER TWO WINS! announcement followed by several lusty moans as the characters on the screen presumably got down to business. Mimi's moans weren't quite as dramatic or over-the-top, but they were still very satisfying - I quickly learned exactly where to put my fingers and tongue to make her breathing go funny, and went to town on those spots.

"H-Hey, Mimi, you wanna take over for a bit? Seeing as your hands are free." Shay sounded a bit desperate.

"My hands are so, so not free," Mimi laughed, squeezing my butt more for good measure, "Buuut, fine. Can't believe Controller Hog Crash is swapping with me so soon!"

"It's Thrash, Mimi!" Shay whined. "C'mon, lemme play with her..."

Mimi laughed some more, and Andrea groaned.

"Sooner she fucks Riley the sooner we can get back to it. Just, like, scoot her over or something." Andrea sounded ready to kick me out already, though I think her friends would have come with me at that point.

Some scooting commenced. Some more scooting followed, then a heated logistics debate. After a minute of working it out, Shay and Mimi came up with a plan that let them both enjoy my professionally amateur services at the same time. Andrea's blankets from her bed were put down on the floor so Mimi could lie on her stomach, resting her chest on a pillow. I laid down on my belly too, behind her and between her legs, still fervently licking Mimi's clit like I'd been told to. I'd tried to go completely without taking my mouth off her pussy, but there were still several awful moments where I had to stop tongue-fucking her. However, this was all in service of getting Shay's cock inside me, and I was beyond excited.

While Mimi and Andrea started playing the game again, Shay knelt down behind me. She slid her hands down my back and gripped my butt cheeks, pulling them wide apart. I could hear her muttering under her breath, chanting quietly, "Fuck, she's way too small! Fuck! Fuuuck..."

In retrospect it probably wasn't that quiet, seeing as I heard her through the earmuffs that were Miyuki's thighs. Shay gently pushed her throbbing cock down between my butt-cheeks, her shaft making contact with my spine ... and the top of my head.

"Fuck! Normally I just use bigger sex toys, 'cause I can fit it in them, but ... she's way too small, isn't she?"

I looked back up at her, a trail of drool bridging the gap between my lips and Mimi's sopping wet pussy. I let my fingers take over for a minute as I got a look at how big this thing was. From this perspective, Shay's cock was even bigger than I thought, and longer than I was. I mean, it was longer than Shay's upper body, so what chance did my tiny body have? However, my body cried out for it. I needed that monster inside me.

"It's okay!" I waved back at her. "I'm the bestest sex toy, so you can... put it in my butt!"

It hadn't been a random choice - I recalled with Lacy how her cock pressed up against my womb and was stopped, while in my ass it slid deeper without stopping. Made sense then that my butthole probably had more room or something? I didn't know what the inside of a human body looked like. Turns out, I'm a genius.

"Y-Yeah... yeah! Okay. Thanks, Riley! I'm ... gonna put it in you now!"

Shay crept back a little, moving back so that the tip of her dick could press at my asshole. Shuffling her knees forward, she sent a foot of dick straight inside me just getting close enough to be in a comfortable position. She swore again, and I shivered in pleasure as I returned to ravenously licking Mimi's clit.

Once she was ready, Shay began some hesitant thrusts. Finding the inside of my asshole to be pleasantly lubricated, even if it was quite tight, her stop-and-start motions turned into rapid-fire pistoning. Shay moved her hips fast, her athleticism turned to rearranging my guts. As she continued, her position leaning over and clutching onto my ass cheeks proved to not be as comfortable as expected, forcing Shay to move a little bit further each time. Every shuffle dragged more inches inside me, and I could feel her cock penetrating deeper and deeper into my body. She was definitely churning up the contents of my stomach, which was almost entirely cum, piss and shit by now. As if sensing some unconscious desire on my part to have her add her own mark, Shay began to cum.

Shay did not, however, stop fucking me. For a solid thirty seconds, Shay's apple-sized balls pumped load after load of cum directly into my stomach as she dragged my insides back and forth. Her backstrokes had such a strange feeling to them that I didn't understand at the time, but I later realised were the result of her slightly prolapsing me. My asshole was clinging to her dick so tightly that it was coming out with her when she pulled, immediately being shoved back in the moment after.

"You nearly done, Shay?" I couldn't see my sister, but I'd heard PLAYER ONE WINS enough times to know that Mimi probably wasn't concentrating very well, and Andrea was getting annoyed.

"Mnngh...! S-So good...!"

"I'll... take that as a no. Mimi, I'm gonna play something else for a bit, you good to just watch for a bit while you, uh..."

"While your five year old sister devours my pussy? Sure." Mimi sounded really content. "Mm, if we're not careful, Shay's gonna stick it through your sistAH!"

I'd felt it before Mimi did, though I doubted Shay was even aware what she had done. As she pushed more and more of her extremely long cock into me, I could feel it sliding up my throat, like getting my throat fucked from the wrong direction. More and more slid up until I could feel Shay's dick in my mouth, sliding over my tongue, pushing open my lips, and... thrusting into Mimi's sopping wet hole.

With my lips pressed against Miyuki's pussy, Shay's cock was able to immediately go out of my body and into Mimi's without once touching air again.

"Shay! Nngh!" Miyuki waved a hand at her, but Shay wasn't listening. "Shay, you're inside me! Fffuck, you really went through her!"

"Woah! Sh-she really is..." Andrea sounded shocked. I'd never heard my sister and her friends having sex before, even though I knew that was something friends did when they were older and bigger and hornier. Maybe they'd never tried Shay's cock inside each other? I felt so lucky to be the first, the entirety of my body from asshole to mouth wrapped around Shay's dick like a masturbation toy. "Mimi, you want me to stop her?"

"Mm! No, this is... wow! Mmngh, y-you gotta try it Andrea, it's so good..."

Miyuki panted loudly as more of Shay's dick slid out of my mouth and into her pussy. Shay was grunting, but she hadn't slowed down a bit. I could feel sweat dripping from her body onto me as she drew closer and closer, and eventually she managed to properly bottom out inside me. There must have been several more inches of cock sticking out of my mouth, but I still managed to keep my tongue out to tease and lick Mimi's sweet clit. However, now that Shay was able to bottom out, it meant her hips were smacking into my ass cheeks with every thrust. The wet, sloshing sound of her dick rapidly moving in and out of me was drowned out by the slapslapslapslapslapslap of our flesh colliding. Shay had completely enveloped my body with hers once again and was resting her head on Mimi's soft ass, her moaning practically all I could hear apart from the slapping.

Andrea later told me that Shay fucked me and Mimi like that for fifteen minutes straight. In that time she changed games, got herself another drink and finished a side-quest before Shay orgasmed again. Mimi had already cum a few times, her squirting wetness leaving a huge puddle in the blanket beneath her. I was, as expected, unable to do anything but orgasm, so orgasm I did. I'm pretty sure I left my own mess on Andrea's blanket. When Shay came, it was the strangest feeling - I felt her cock pulse with waves of cum, all of it passing through my body but not going inside it. As excess washed out of Mimi's pussy, I lapped it all up as best I could with my mouth filled with throat-bulging dick, tasting it as much as possible.

Shay slowly pulled herself out of me, her cock softening up. I orgasmed one last time at the feeling of it all sliding out of me, and I was entirely unable to move. I might have passed out, I can't remember - I mean, I'd lost my virginity in every hole that day and already been fucked by three different people in many different holes! It was understandable that I, a five year old girl, was feeling a bit tuckered out.

The next thing I remember was sitting in my sister's lap, bouncing on both of her cocks. It felt like the most natural thing in the world - looking over, Shay and Mimi were back in their bean bags, and all three of them had started watching a movie. There was pizza too, and I enjoyed a little piece as Andrea's dicks rubbed up inside my ass and pussy.

"Thought I'd knocked her out," Shay laughed sheepishly. "But look at her - happily bouncing away. Not so annoying now, is she?"

"Mmgh." Andrea shrugged, her hands on my hips as she slowly lifted me up and dropped me down. "S'pose she's good for fucking now."

I am good for fucking, I thought for myself. But what was that other thing? ... Oh yeah!

"Poop! Gimme poop!"

"Huh?"

I swallowed down the last of my pizza slice and opened my mouth wide. The girls looked confused for a moment before Mimi laughed.

"Oh yeah, I heard that sex toys can live entirely off cum and stuff."

"Is that true?" Shay sounded fascinated. I watched as she opened her phone and searched it up. "Wow. Says, a properly equipped free-use sex toy can live happily and healthily entirely off the urine, feces and semen of other people without needing any other sources of nutrition. So, your sister, like, only needs to eat poop now?"

"It said properly equipped, right?" Andrea shook her head, though she hadn't stopped fucking me. "I mean, if she finishes all this program stuff, then she'll get a body mod for it. But, like, she still has to eat normal stuff now."

"Nuh-uh! I can eat aaaaall your poop, and drink all your pee! 'Cause I'm the bestest toilet ever!" The girls laughed, but that just made me grumpy. "It's weally true! Try it! Aaah..."

"Alright. I kinda needed to go anyway." Mimi picked herself up. "Pee first, then poop. Sure you're not gonna spill it everywhere?"

I shook my head. How could I ever waste a single drop?! Mimi stood in front of me, blocking Andrea's view of the movie - I don't think she cared any more, her pace at sliding me up and down her twin dicks growing faster.

Miyuki pushed her pussy up to my face and peed straight into my mouth. Hers was warm, a bit sweeter than Lacy's pee but no less tasty, and I drank it all down greedily. Andrea fucked me harder and harder as all that piss flowed down my throat, though she had to reposition herself as Mimi pushed her asshole into my face. She didn't have as much poop in her as Lacy, but there was still plenty - a whole bowl of chocolate pudding slid down my throat as I employed my open-throat technique once again. Once Mimi's body stopped pushing for me, I quickly swallowed it all down and cleaned her up with my tongue.

As I washed Miyuki's asshole, I felt two blooms of warmth inside me - my sister was cumming. With a soft grunt of exertion, Andrea bottomed out inside me and filled both holes with her seed, her cocks going soft inside me. Still, she didn't pull them out. I thought she was just comfortable, but my sister was thinking ahead.

"My turn, then." Shay's flaccid cock was a bit funny to drink from, but I pulled the tip into my mouth and then sucked down to pull more inside. Shay grunted in surprise as her soft dick slid a few inches down my throat, and I felt the warmth of her pee in my hands moments before it splashed down into my stomach. I couldn't help myself with Shay's cock, my hands stroking and enjoying her smooth skin, my tongue tasting it. The poor girl was starting to get hard again, and she had to take a step back before she could reposition. She didn't have any mercy for me this time, and crammed half her dick down into my throat.

Andrea had a laugh at that, a bit of a I can't believe how ridiculous this is getting laugh. Once again I felt warmth down in my bowels and in my womb as Andrea loosed her own bladder into my body. My belly was now thoroughly round from all the stuff inside it, and I looked like I was a few months from giving birth.

"I could get used to this," Shay grinned, slipping a bit more of her dick down my throat. "Mm, fucking this little hole is so much nicer than bigger sex toys... Ah!"

"Woah! You..."

Shay had, once again, slipped far enough through me to touch someone else. Specifically, I could feel as the tip of her cock pushed at the tip of one of Andrea's dicks, both jostling to push past each other as they sprayed liquid gold inside me. The girls grunted at the sensation. Then, Shay moved further in.

I think she meant to step backwards and stumbled, catching herself by clutching the sides of my head. However, Shay pushed her dick further inside me and bottomed out, and I felt a very peculiar knot inside me. Both of the girls squeaked in surprise.

"Y-You're inside my dick, Andrea!"

"F-Fuck! Oh, fuck, your pee is...!"

Shay tried to move again, but had herself tangled on a cord. Andrea couldn't move at all, underneath me and with Shay looming over her. So, for a frantic several seconds, my sister's dick penetrated the cockhole of one of her best friends, and Shay peed down into Andrea's bladder. When she finally got free, a burst of warm liquid sprayed the inside of my asshole as the two finished peeing. Shay slowly tugged her dick out of me, huffing away. I sucked as hard as I could to stop her getting away, but unfortunately my suction was no match for her strength.

"Riley," My sister panted, pulling me off of her lap, "You are so dangerous."

I smiled brightly. I smiled even more when a wave of pee and cum sloshed out of me and soaked Andrea's blanket.

The girls did make good on their promise to feed me their poop, though Shay and Andrea took some time to recover from their unexpected dick penetration. I slurped down the relatively meager contents of Shay's asshole, shortly followed by my sister's shit, all the while knelt on Andrea's soaked blanket. It smelled so good, and I just wanted to curl up in it and go to sleep. I was full enough to fall into a food coma, after all.

After Shay and Mimi went home, mummy came in to check on us.

"How did you go-- oh, wow. Messy living starts now, huh?" Mummy chuckled, seeing me laid out on the soaked blanket. "You want me to clean that, An?"

Andrea shook her head. She was sitting back on her beanbag, the fabric of that similarly stained. "I think I kinda like it, mum."

"Well, that certainly saves me some time! Riley, you... wow, they really used you, huh?"

My pussy and asshole were still gaping open, slowly leaking fluids, and my belly was huge and round. I nodded happily.

"Mummy," I asked, a cherubic smile on my face, "What's messy living mean?"

"Oh! I was reading this article online that said how just forgetting all about cleaning up the messes really saves on time and makes everyone happy! So, I guess all the mess you'll be making from your training totally counts, huh?"

"Wait, she can just get pee and stuff everywhere?" Andrea looked up, raising an eyebrow. "That ... might be nice. Can I make mess too?"

"Sure!" Mummy nodded. "It'll bring us all closer together, or something like that. Though, you should probably still use your sister as the toilet for now, so she can practice."

I looked at Andrea, at my mummy, and at my bloated tummy. "What do I use for a toilet, then?"

"Um, the toilet, dork." Andrea poked me in the ribs.

"Or the floor, or your bed, or anywhere, I guess! That's what messy living's for!" Mummy gave a little cheer. I cheered loudly too as she scooped me up and gave me a hug.

"Then, I'm gonna go!"

Without any more warning, my asshole loosened and my bladder opened up. A fat log as thick as my thigh snaked its way out of my asshole and down to the ground, while a torrent of piss cascaded down mummy's chest. Mummy stared down, bemused.

"Huh. That's actually quite nice."

"Feeels sooo goood ..."

"Gah, Mr Snuffles! She's peeing on my stuffed toys! Muuuum!"

See, everyone? I wasn't even a sex toy in training, and in the span of a single day I'd relieved several people and brought my family closer together! If you still don't believe me that free-use sex toys are the most hard working, vital parts of society, then... well, keep reading! That was just the first day of my training, and I've got so much more to tell you!

Notes:

Next time - the Free-Use Sex Toy Program! What strenuous training will Riley get up to? Feel free to leave some suggestions, I'd love to hear from you!

Chapter 3: First Friday Program

Summary:

My first day in the world of being a free-use sex toy (in training) was crazy! But once I got on the ride, there was no way I was getting off - so lemme tell you all about the program! Well, let's see... wait, this is just the chapter summary! Argh! Okay, so, in this chapter I start my lessons in the Advanced Program, make a few friends who are (almost) as crazy about sex as I am, and settle into a comfortable family life as the household toilet and cumdump!

Notes:

(See the end of the chapter for notes.)

Chapter Text

After one crazy day (and yes, those last two chapter's worth of things I just told you? That pretty much all happened on the one day!) I had learned many amazing things about myself. Some of them I only really thought of in retrospect, but that's what I'm here to do now! Retrospect! And give you some lovely descriptions to help you relieve your needs. See? Even if we're not in the same dimension as one another, I can still be a wonderfully relieving free-use sex toy for you! Right, retrospect. Don't get distracted, Riley!

First, I learned that I loved sex. I didn't just like it, like one might like ice cream or petting puppies, I loved it. It was the kind of love that made you want to revolve your entire being around something. I wanted to know everything about sex, to have sex in every way you could have sex, then make new, more ridiculous ways to have sex and do those!

Second, I learned that I also loved being a toilet. If I had to choose which one I liked more, it'd be sex by a slim margin. Having someone else inside me, or relieving someone else's sexual desires, those felt great! Having someone's waste inside me also felt great, and tasted great, but it's a different kind of great, you know?

Last on my list of realisations was that my body was really suited to the job. Like, normal five year olds in my world can't just take a dick all the way through them and eat half their weight in shit! Even for my world, this is unusual behaviour! Of course, people could always get their bodies modified and augmented to take things better, a luxury that is sorely lacking in your world, but I was just li'l Riley Evergreen, five year old sex fiend and absolute natural at being a free-use sex toy! The explanation the doctors gave me was waaaay too complicated to remember, but the simple version is that my insides are just aligned different! Everything's more squishy and moveable and snaps right back into place afterwards.

However, even my crazy body wasn't going to be enough for the job - eventually I'd need augments too. I mean, have you seen the kinda stuff a sex toy goes through daily?! ... Oh, right, you haven't. Well, I'll tell you all about it! But first, the program.

The important part about the program to remember is that it wasn't every day. From Monday to Thursday, I attended school like normal. It was fairly boring stuff, but being a super genius girl who only cares about sex makes it hard to concentrate when you have to learn to add numbers and read letters. That stuff was easy, I figured all that out ages ago! I spent most of the school week staring at my teacher, Mrs O'Farr.

Mrs O'Farr was a bit older than my mums. She was fairly tall, though most adults look tall when you're five years old. Mrs O'Farr was pretty and curvy, with heavy breasts that remained in her dress shirt mostly by force of will. Her short skirt also did nothing to hide her thick thighs and fat cock, that ten-inch beast constantly waving in front of my eyes like bait on the end of a hook. It was thicker than both my arms combined, paired with some hefty balls - those always made my mouth drool, thinking about the warm, sticky cum contained within. Did I mention I was a little bit sex-obsessed?

I always thought it was weird, Mrs O'Farr's insistence on wearing clothes. But when I saw the fabric clinging to her ass, or peeked a glimpse of her nipples through the material of her shirt, I always got a bit more excited than normal. In that regard, I think Mrs O'Farr was the most unintentionally seductive woman in my early life.

Of course, Mrs O'Farr was also used to teaching five year olds, which meant being used to being randomly touched. There wasn't really anything random about my groping hands, but she laughed it off or ignored my grabbing all the same. The first week of school after my successful entry into the program, I was constantly clinging to her. When I spoke to her, I did so while hugging her around the waist, letting her flaccid cock rub against my flat chest. Sometimes I openly stroked it, often unintentionally, though Mrs O'Farr always made polite excuses to remove my hands. My favourite challenge was trying to undo as many buttons on her shirt before she stopped me, and by the end of the week I managed to take that last button off with a combination of sleight of hand, well-timed distractions, and the help of a new friend I'd made. When those massive tits spilled out, she looked down in surprise at what I'd done and laughed at how sneaky I was. She didn't bother doing her buttons up again until an hour later, and I like to think it was a little reward for being so clever - I never paid more attention to her than when those tits were waving in my face.

My new friend was a girl named Yvee. She was not in the program, and not remotely as interested in sex as I was, but she was funny, clever, and very very cute. I definitely had a crush, though I didn't know it at the time. Slightly taller than me with coffee-brown skin and dazzling green eyes, we bonded over our mutually shared eye colour. Her hair was kind of frizzy and curly brown, kept in a pair of wiggly pigtails that I thought were super cool. Yvee's skin was super smooth, she smelled amazing, and she liked Pretty Puff Power Girls too, so we got along pretty well. Despite her general apathy towards sex, she thought it was amazing that I got to be in the free-use sex toy program!

"It's like you alweady know what you're gonna be when you gwow up!"

"Yeah! I'm gonna get fucked a lot!"

"Language, Riley!" Mrs O'Farr called out. "You can say, having lots of sex."

"Mm... I'm gonna habing lots of sex...?"

Yvee and I giggled, and Mrs O'Farr smiled and sighed, gently prying my hand away from where I was slyly jerking her off. I think she was counting the days until my first lesson in the Program, to hopefully tucker me out and make me a little less horny. Oh, Mrs O'Farr, you were so very wrong.

Despite Yvee's extremely normal attitudes towards sex, she did personally enjoy using sex toys as toilets. This was also a fairly normal attitude to have, all things considered. Using sex toy girls as toilets was far more comfortable and convenient than cold porcelain and plastic seats, and most people choose the former if its available. Which is why, in the middle of the week following my examination, I discovered where Yvee kept running off to when she said she needed to use the bathroom. Our junior classrooms had their own attached toilets, ordinary ones made a little bit smaller for little legs and bums, situated at the back of the classroom. I'd used those when at school on the first week, and had simply held it all in for when I got home on Monday and Tuesday, but Yvee never used them, not once! So, when she wandered off somewhere at play time to the big kids' bathroom, I had to see what all the fuss was about.

There was the normal array of toilets, lined up against the walls and entirely exposed (privacy is not a concern when you spend your days naked anyways). A few older girls looked at me as I stared around, wondering if I'd ended up lost in my new school, until I spotted and ran over towards Yvee. She was waiting patiently for her chance to use a particular toilet - a living one! I hadn't realised that the school had toilet girls, but my silly kid brain clicked two-and-two together - on her hands and knees being used was the same sex toy I saw on my first day of school! The super cool girl that had impressed upon me the awesomeness of sex in the first place!

"Hi Riley!" Yvee waved. "Did you wanna use her too?"

I nodded. Duh! I had to meet my hero, of course. But, I would have to wait my turn too.

There were two girls using her that time, both older than her. One was gently fucking her from behind, while the other urinated into the sex toy's mouth, lips clamped around her pussy as she gently slurped up every drop. The two girls, likely in their last year of primary school, were happily chatting about random older girl stuff as they used her.

"You alright, kid?" The one using the sex toy's asshole to relieve herself looked over at me, catching me staring as I gently masturbated. "Lost? This is the big girl's toilets."

I shook my head. "I wanna use her too. She's pwetty."

Both of the girls shared a look and laughed.

"I mean, I guess," said the one peeing in her mouth. "Here, she's all yours."

"Gimme a sec... ungh!" The first girl slammed her hips in with a soft plap! I knew she was coming. I licked my lips. "There we go. Have fun, kids!"

Yvee went for the sex toy's mouth. I wanted to use her mouth too - and wanted to talk to her as well - so I just waited my turn.

"I saw you on the first day of school," I told her. "You were sooo cool!"

"Hmm?" The sex toy, who had been mostly zoning out until then, looked up at me. She smiled really nicely with her bright blue eyes. I couldn't help but notice that her face was wet with cum and pee, and her hair was messy with it too. I was a little jealous.

"I'm gonna be a sex toy too! I'm gonna be the bestest one ever!"

The girl mumbled out something, but I couldn't hear her - with her tongue sliding in and out of Yvee's pussy as she drank up the little girl's pee, there was only much she could do to speak. After she had licked clean Yvee's clit and peehole, but before the girl turned and pressed her asshole up to her mouth, she got a chance to speak.

"That's really great! Just looking at you, I can see you're gonna be a great sex toy." She raised a finger and slid it up between my pussy lips. I hadn't realised that I was soaking wet, and my legs quivered at the unexpected attention. "Hey, you can use any part of my body for your toilet if you w-mmph."

Yvee cut her off without a second thought, already shitting down her throat. The sex toy dutifully returned to her work.

"I've got lots," Yvee gave me an apologetic look, "So I'm gonna be using her mouth lots."

She gestured me towards the sex toy's backside, and I went around there to do my business. The mouth was definitely the best part to use for the toilet if you didn't have a penis, but there was nothing stopping me from using any of her other holes. Both her pussy and asshole were gaping open slightly, drooling with cum and pee from countless girls in the school who had been using her all morning. I licked my lips and, without thinking, dropped down to my knees and pressed my face into her cunt. The sex toy didn't show any sign of surprise, but Yvee did.

"What're you doing?! That's gross!"

"Mm, s'not," I protested, my tongue slurping greedily at all the waste in the girl's pussy. "It's so super tasty! Mmm..."

Chocolate cake, apple pie, cream filling, so many wonderful flavours crossed my tongue as I drank straight out of the dirty toilet that was this girl's vagina. Having retrieved all the easy stuff from her pussy, I swapped to her asshole and had my fill there too. By the time I was done eating her out, Yvee had finished her business. Standing up, I got to watch as the sex toy professionally licked the girl's anus clean - I couldn't wait to learn how to do it properly. Gently holding the toilet that was the girl's asshole open with my hands, I peed into it - I hadn't really needed to go that badly when I got here, but it almost felt rude not to. After all, she was working so hard to service us, so she definitely deserved to feel the treat of that warmth inside her.

As we left, the girl called out to me.

"Which program are you in?"

"Adbanced!" I made a superhero pose, hands on my hips with my legs wide. "'Cause I'm the bestest."

The sex toy girl just laughed. "Yeah, figures! I'll see you there on Friday, then!"

I waved goodbye, just in time for another girl to calmly shove a pair of dicks straight down the sex toy's throat. She was such a cool sex toy, and I couldn't wait to be that cool too.

Just like the previous week, I was perpetually vibrating with anticipation for Friday. The last day of the week was when I had my program activities scheduled, for the last half of the day. The idea, I learned later, was that if the program's rigorous exercises wiped you out (which, given its intensity, was very likely) then you would have all weekend to recover. So, my week was spent waiting.

My home life had changed entirely. The 'a bit of time each night' suggestion of my homework had been disregarded entirely, and I was permanently everyone's living toilet and sex toy. In the morning, mummy slowly transitioned to waking me up with her cock - the first time, she had apologised for waking me up (as though a woman twice my size lie on top of me and pound my asshole wasn't going to wake me), but from then on it was just our morning routine. Mummy entered my room, gently crawled into my bed and fucked my ass to wake me up. Then, I'd get dressed (read: pick out whatever socks I was going to wear that day), let mummy piss down my throat as she did my hair, then had breakfast with a side of her poop.

I couldn't subsist entirely off waste yet, but everyone made a point of using my body for their toilet whenever possible. Andrea usually woke up a bit after I started having my breakfast, and always needed to pee first thing in the morning. I was still having trouble fitting both of Andrea's dicks into the same hole at once, so usually she just lifted me up and slid one cock into my pussy and the other into my ass.

Then, school. As you've probably already pieced together, waiting through the school day without getting pounded by someone was agonising. I had managed to convince Yvee to let me drink her pee a couple times, but she thought it was a little weird - after all, I wasn't really a sex toy yet, so it was unusual. The equivalent in your world would be using a bathroom or just peeing outside - some people are just a bit too squeamish to use a not-quite-even-in-training yet sex toy when they could just go use a real one. At the very least, Mrs O'Farr didn't mind me masturbating vigorously during class, though she was starting to get annoyed at the amount of classroom toys I kept coating in my pussy juices. I was especially forbidden from going anywhere near the whiteboard markers after I bet Yvee I could shove all ten inside me at once.

Then, back home. Mummy fucked me almost immediately after we got home, usually over the kitchen bench or on the lounge-room couch. On Thursday she didn't even make it that far - we stepped in and shut the door behind us, then mummy picked me up by the waist and fucked me right there in the hallway, pounding me up and down like the little sex-crazed gremlin I was. I loved every minute of it, especially when she let me lick her dick clean from whatever hole she decided to shove her cock into.

Our house was starting to get really dirty, and it was almost entirely my own fault. If someone overloaded my body with waste, I was allowed to just let it out wherever I want - and mummy's new 'messy living' plan meant that she wasn't bothering to clean it up. Logs of poop, puddles of pee, splashes and drips of cum filled the house, on the floors, splattered on the walls, and in one spot in my room after Shay had paid a visit one day, right on the ceiling. Shay had held me up and fucked me after I told her that mummy had done the same just an hour before, and her blast of semen nearly removed some of my glow-in-the-dark ceiling stickers when she bottomed out through me. I loved it when Shay did that.

My only regret was that Mama didn't show up for the whole week. She was usually away on business trips, but she would be home soon - I couldn't wait for both of my mums to have sex with me... at least I would have some of my new sex toy training!

Friday came. The school morning passed by agonisingly slowly. I spent almost the entire morning rubbing my clit furiously at the thought of what could possibly be awaiting me, but I think if I'd known how hard they would work me... ah, who am I kidding? I would have masturbated even harder. Yvee was even kind enough to let me drink her pee and eat a fat log of poop right out of her ass, though she got a bit annoyed at me when I tried to stick my tongue inside to clean her out properly. She was a very funny girl.

When the middle of the day rolled around, an older girl knocked on the door of our classroom and came in. Around 11 or 12, she was of fairly average height with a somewhat scrawny build. She wore her long brown hair in a loose ponytail that reached the middle of her back, and her soft, slightly sleepy face dazzled with sparkling hazel eyes. Hanging between her legs was a long, soft cock the length of my arm, resting over the top of a pair of enormous balls. After a quick explanation to Mrs O'Farr at the door, she walked over to me, kneeling down to my level.

"Hi there! Are you Riley Evergreen?" Her voice and smile was really pretty, and I was immediately struck with the desire to kiss her. I settled for mindlessly grabbing her dick, which she surprisingly didn't mind at all.

"Mhm! You're weally pwetty."

She blushed at that, giggling. "You're so cute! I was so surprised to hear there was two 5 year olds in the advanced program this year! And you're certainly eager. C'mon, time to go!"

I stared at her, open-mouthed. It was time. I let go of her dick and reached up, grabbing her face to kiss her. "Let's go!"

We walked hand-in-hand out of the classroom. She had the same reaction to me kissing her as she did to me grabbing her cock - absolutely none whatsoever. The lights clicked on in my little brain.

"Are you a sex toy?"

"I sure am!" She squeezed my hand. "You're so clever, how'd you know? My names Amy, and I've been a sex two for two years now. This is my first time helping out with the advanced program, so it's kinda like both our first times?"

I nodded. Amy knew that someone my age couldn't have possibly been in a beginner's program already. She knew I was different. We understood each other, one sex toy to another (in-training-almost). But, my mind zoomed back through the conversation and picked up the other fun fact I somehow missed. Halfway down the hallway I stopped.

"... There's another five year old like me?!"

"Yep, just like you. Well, not just like you... c'mon, we're gonna be late if you stand around here!"

Well, that certainly got me moving. I nearly ran down to the program room. I wasn't going to be late, because I was gonna be the bestest sex toy ever, and I was going to make lots of friends with other cool sex-toys-in-training! We stood outside a simple black door, just like any of the other classroom doors, but this one was clearly the right one - I couldn't quite read the small writing all the way up the top, but a big poster with a pair of naked girls embracing each other on it explained the purpose nicely. In big, bright letters, it said FREE-USE SEX TOY PROGRAM! Making Friends Inside! One of the girls sported a big cartoon cock, sliding up into the other's womb - a cross-section view showed a cute heart-shaped spray of cum inside her, complete with its own smiley face.

As it turns out, Amy was just being dramatic about our tardiness - we were actually a little bit early. My classroom was far enough away that she had to come get me, while almost everyone else had come down to the room themselves, and Amy had somewhat overestimated how long it would take to get me. So, when she pushed open the door, I still had plenty of time to gasp in surprise at how amazing the room was.

The Program Room was larger than a normal classroom, cleanly divided into different sections. On the near side was an assortment of desks and a big TV screen, for normal classwork. Behind that was several rows of soft beds, accompanied by racks full of various equipment. Dildos, butt-plugs, beads, vibrators and onaholes were all lined up neatly on shelves and racks, all the equipment varying dramatically in size and shape. There were ropes, chains, hooks and mounting points for various bindings, and even a few larger devices that I didn't know the purpose of yet - some of them looked like you might climb inside them, but I wasn't sure why. At the very back of the room was a tiled area, split in two again - one side had a locker room area with far more cabinets than necessary for just keeping people's clothes, and the other side had a low, empty pool. I didn't know what any of it meant, but I was excited.

There were seven other girls here, once everyone had arrived. There was three older girls, around the same age as Amy, all three sporting rock-hard dicks. Those girls were sitting at a table together talking excitedly as they bounced up and down on the spot - I realised then that all the classroom seats had a pair of dildos installed in them, and that the girls were bouncing on those. Three more girls were sitting together, each around eight or nine years old. Two of them didn't have penises, but the one that did had two of them, and sizeable breasts besides. The big-breasted girl looked surprisingly top-heavy, even as the other two sucked her cocks. She smiled at me when she spotted me watching, and I waved back.

Finally, there were two other people in the room - the final student and our instructor. That student was the promised girl the same age as me, and I saw immediately what Amy meant when she said we weren't quite the same.

At age five, I was not a terribly tall girl. I'm still not! However, this girl was even smaller than me, as short a girl as I'd ever seen. Which made her set of three foot-long cocks look all the more ridiculous, stacked one on top of the other, erect and dripping with pre-cum. A frizzy, curly mess of dark brown hair bounced off the top of her head, and wide brown eyes and soft lips made her look as cute as a doll. She looked so nervous, arms huddled close to her chest as the instructor calmed her down, but something seemed to relax in her when she saw me. Maybe she was glad to see another girl the same age as her, or maybe she was just relieved to not be surrounded by people way taller than her.

Our instructor was massive, in more than one sense. When she stood up, she was twice Amy's height with a toned physique. Heavy breasts, heavy balls, and a thick foot-and-a-half long cock made her look more like a sex goddess than a school teacher - but who was to say she couldn't be both? She had short blonde hair that matched her steel blue eyes and not-quite-tanned light skin. Both of her nipples were pierced with shiny silver bars, as was both of her ears, her belly button and her tongue. For some reason, I was extremely excited about that tongue piercing, but I wouldn't get to find out why until later.

Once everyone was sorted, the instructor had us all come sit in a semi-circle on the floor. I sat down with Amy on one side of me and the smaller girl on the other. Around the circle of people, I could tell everyone was quivering with excitement - though the small girl seemed to mostly just be quivering.

"Welcome, everyone, to the advanced free-use sex toy program!" The instructor, kneeling in front of us all, had a slight accent that I really loved hearing. She was also quite loud - the nervous girl jumped when she started speaking.

"All of you have either finished your time in the standard program," she nodded towards the majority of the group, "Or showed exceptional readiness during your examination!"

At that one, she looked at me, the other girl next to me, and one of the big-breasted girl's friends, an angel-faced Asian girl.

"Let's start with introductions. My name is Mika, and I will be your instructor for the year. We will be having a wonderful time together, I am very sure. Over here is my lovely assistant..."

Mika gestured to Amy, who waved and introduced herself too. "It's my first time helping with the advanced class, and I can't wait to help you all prepare for your lives as sex toys! I can already tell you guys have what it takes to go the distance and devote your bodies to relieving people. I know some of you are older than me, but I've been through the entire sex toy program and spent a few years working as a sex toy, so I hope my experience will be super helpful for you. Now, on to you, Riley!"

I was a little surprised to be going first on introductions, so I showed the meekness of my nature by standing up, putting my hands on my hips and saying, "My name is Riley Ebergreen and I'm gonna be the bestest sex toy ever!"

Mika and Amy clapped, as did the older girls, but my shy new friend just seemed confused. I sat down and smiled brightly at her - hoping to give her some of my courage.

"I'm Dana..." Her voice was so tiny, and everyone leaned in to listen. "I'm... a bit shy. Um."

After a moment's awkward silence, we moved on. The angel-faced girl was Yumi, her big-breasted friend was Darla, and the last of their trio - a blonde-haired girl with big, soft lips - was Charli. The older girls gently stroked themselves as they introduced themselves - Fey, Cleo and Kim. There were so many names to remember, but everyone was more eager to get into the main event than to talk about their hobbies and whatever. We all knew what everyone got up to outside of school, especially in this group.

"Okay, great to meet everyone!" Mika hopped up and went over to her desk, waking up her computer. "Now, every session we have in here is going to be devoted to learning about a new way for us to have sex, or practicing our skills as sex toys. Today is no exception! Today we're going to learn about... Urethral sex!"

Mika changed the screen to show a slide presentation, the first page showing a close up of the tip of a dick and a girl's peehole. Most of the other girls seemed really excited, but it took a bit for me to figure out exactly what was going on.

"Oh, peehole sex!" I remembered when Lacy, the examiner from last week, pushed her thumb inside my peehole. "That's so cool!"

"I-Inside there...?" Dana murmured, just barely audible. I looked over at her, and saw all three of her cocks spray out a tiny bit of cum. Did she orgasm just from thinking about it?

"It is really cool, Riley!" Mika gave me a huge thumbs up. "Now, have a look at this picture here."

Changing the slide, she showed us a cartoon image of an intersex girl, similar to the one on the poster on the door. With another click, it showed us two diagrams - one of the girl's dick and pussy, another of the girl's insides. Mika gave a quick explanation to us all about how our insides worked, and how intersex girls differed from girls without penises. The general difference was that intersex girls had two urethras, - an upper and lower one, both of which connected to the same bladder. If a girl had more penises, she had more urethras - simple as that! Some of the explanation was a bit tough for me to understand, but there was some special muscle that intersex girls could use to choose which one to pee out of. Even more exciting was that a well-trained bladder could be just as malleable as our wombs, able to stretch and expand when entered from either direction.

As a practical demonstration, Mika and Amy handed out long, thin rubber rods to each of us - one per urethra. I felt a bit silly with just one, especially when Dana got handed a full four, but I wasn't complaining about getting to learn something cool and new. I had hoped for something larger, but given how nervous some of the older girls looked about it, I guessed that it was so they wouldn't be so scared. Classic, over-confident Riley Evergreen.

Mika and Amy showed us how to insert the rods by pushing their own sets into themselves. Mika's rod looked almost silly inside her massive cock, but she slid it in with ease. Amy bent over to show everyone her pussy, and hers went all the way inside without a problem. Everyone in the classroom grabbed a rod and prepared themselves.

I spread my legs out and spread my pussy lips with one hand. As an experiment I slid the rod inside my pussy, drenching it wet with my juices. It tickled a bit inside there, too small for my hole to get a proper grip on it - I had been spoiled with big dicks, and this rod was barely as wide as a finger. Once it was properly wet I lifted it back up, lined it up with my peehole and pushed.

The first part was easy, the strange new sensation of a hole that had barely been touched filling me with giddy joy. But, once my rod poked its way into my bladder, a far more intense feeling rocked me. My legs quivered as the uncanny sensation of peeing in reverse assaulted my senses. The rod had slid along the bottom of my bladder, and as I pushed it further inside it poked at the back. It felt like I desperately needed to pee, and sliding out the rod gave me as much joy as letting everything out after having had to hold it in all day. I very quickly worked into a rhythm, alternating between that feeling of bursting fullness to sweet, sweet relief. I rubbed my clit with my free hand as I slid it in and out, and looked over at the rest of the group.

All the others were taking their time, easing things in ... except for Dana and Yumi. That sweet, angelic eight year old was moving her fist back and forth like she was jerking off a dick, ramming the little rod in and out of her urethra to the tune of quiet, rapid-fire squeaks of pleasure. Dana, on the other hand, was slowly pushing rod after rod into her body - having the most holes of us all to practice this technique with, she shoved a rod down each cock so far that they couldn't be seen any more. As she pushed the last one into place, I think Amy spotted her and squawked in surprise.

"D-Dana! Careful, if you push them that deep they'll be really hard to get back out! Ah, geez, they're all in there, aren't they?"

Amy got up, looking around for something to help her retrieve them, when Dana slid two fingers into one of her cocks and gently pulled it out like it was no big deal. I shivered in sympathetic pleasure at how easily she reached into her own dicks, and watched fascinated as she pulled out each one. Every rod came out with its own little blast - three separate squirts of cum, and one spray of piss. Dana's bladder, its floodgates forcefully opened, kept trickling liquid gold onto the floor for a full minute. Not that Amy seemed to mind that part.

"Have you had urethral sex before, Dana?"

"Mm, no... it's just... I plug them." Dana looked down at her dicks, as though a little ashamed of them. Those chocolate brown shafts twitched happily - at least some part of her was proud of itself!

"Plug them?" Amy didn't understand, and I was quietly impressed to see the real sex toy here confused by this. I decided then and there that Dana was really cool.

"Well, when I ... start cumming ... I get a little ... crazy. So I hafta plug them." Dana mumbled away. Another small squirt of cum splashed out of her dicks, and she jumped in surprise as most of it went on her face. I couldn't believe my eyes - had Dana just surprised herself with her own cum? I laughed out loud.

Dana looked ashamed, but changed to surprise when I bowled her over with a hug.

"You are so cool, Dana! Super, super cool! Your cocks are super weally cool too!"

She gave me a look, like she couldn't believe anyone would think that. "Weally?"

"Weally! I wish I had lotsa dicks! Can I play with yours? Maybe we can try some yoo-ree-thal sex?"

I looked at Amy for approval, and she gave a nod.

"Urethral. And you can certainly try! If you get stuck, don't struggle, just wait for me to help."

Well, that was that. I had permission, and I had a hole that now knew it wanted to be filled. Dana just looked nervous, but the way she licked her lips I could tell she wanted it too. I laid down on my back, lifted my legs up and out to expose my pussy like mummy had showed me, and smiled at Dana. Then, something happened.

Dana looked down at my crotch, and a spray of cum squirted out of her cocks all over my belly and chest. She looked up at my chest, and came again. Then, at my face, as if to say sorry before cumming one more time. Then... she broke into a grin. Her face changed from shy and nervous to smug and confident in a single moment. Her cocks were now twitching rapidly, cum leaking out of her. I heard a loud splortch, and saw something drop down between her legs. You see, stupid me, I hadn't noticed something missing about Dana. I hadn't noticed that I couldn't see her balls the first time. When two orbs the size of oranges slipped down out of her pussy, I realised she had been hiding them. When they pulsed, and grew bigger, I realised why. Her balls expanded in size as the cum trickled from her cocks, her body producing more seed than she could possibly hold onto.

"Fuuckk..." Her cute, breathy voice shivered with unbridled energy. "I'm gonna fuck you full, Riley."

Without a moment's more hesitation, she lined herself up and slid inside me. One cock into my ass, one into my pussy, and the last into my urethra. I could feel each of the three through the walls of my own flesh, pressed against each other and oozing constantly with warm cum. I was surprised how easily her cock slipped into my bladder, but my whole body tensed as she touched the back wall - I had just discovered my secret weak spot. When she pushed further against it, I changed from cool and confident to writhing and babbling, clutching hard at my own thighs as I orgasmed uncontrollably. I didn't have any choice but to quiver and moan as Dana mounted me, sliding all three members all the way inside me with ease. Her balls continued to grow, producing more and more semen to pump inside me in ever growing quantities. There was a sudden shift in speed - as Dana started thrusting back and forth, every thrust inside came with an intense spray of cum.

My bladder filled up almost straight away. I wasn't used to having so much liquid in there, especially not lately when I had been so used to just peeing where I was standing at home. Now the contents of my bladder, which was entirely Dana's cum, had nowhere to go. I felt my eyes rolling into the back of my head as she churned up my filled bladder, stretched my womb that was quickly approaching the point of bloating out. I was starting to taste it too, as her cum began to flood my belly.

For two minutes straight, Dana fucked me without holding back. The longer she went, the more intense her thrusts became, and the more intense her cumshots were. Both of her balls had expanded to the size of basketballs, and I clutched onto Dana for dear life as she fell onto me, our chests pressed together as my belly bloated and pushed against hers. Then, she whispered in my ear.

"I'm gonna cum. S-Sorry, Riley."

She leaned back, and I immediately lost sight of her. As my brain caught up on the reasons behind this vanishing act, it came with an immense feeling of heat inside me. Dana had just cum easily a liter of semen out of each of her cocks and poured it inside me... in a single blast. My belly had bloated up so fast that my brain could hardly register it, and Dana had disappeared behind the mountain of my own cum-gut. Then, she came again. A huge burst of semen poured out of my mouth and nose, a waterfall of overflowing cum following it as Dana came for a third time. Then, a fourth, a fifth, a sixth, and finally a seventh time. When she was done, I was more cum than girl - my belly was so large that I could have fit myself twice over in there, and when Dana pulled out all of my lower holes joined my mouth in pouring out endless torrents of cum.

Before I blanked out, I saw Dana's worried face right next to mine. I think she was saying sorry, but I couldn't for the life of me understand why anyone would apologise for doing something so awesome. This was the best day of my life, and it only got better from there.

Leave me a comment, and tell all your similarly-inclined friends! I do have other story ideas I want to write, so your commentary may very well shape the content of those stories! Or something like that. I just like to hear from people, mostly!

Imagine, there I am lying on your bed, kicking my little feet in the air and twirling my hair as I say, "Which part was your favourite part?"

Well, which is it? Huh?! C'mon, tell me, I can keep a secret!

Chapter 4: Getting Stronger Every Day

Summary:

I know, I know, you probably think I'm exaggerating when I say that free-use sex toys are hard workers, and that we go through a lot of stuff. What if I told you that our first session was just the warm-up? Little me of the past still has so much to learn about being a sex toy! Hang in there, Riley!

Chapter Text

"Yvee, come help me find my new friend!"

It was Monday of the following week, at morning recess. Last Friday, after I passed out, I woke up in my mummy's arms several hours later, confused but ultimately extremely excited to tell my mum about what happened. I had spent the entire weekend waiting for Monday, to find Dana and thank her for showing me such an amazing thing, but after several minutes of searching the playground I had been entirely unable to find her. So, I recruited Yvee.

"Is she the one who filled you up?"

"Mhm! It was so good! You gotta try it some time!"

"Um... I'm not crazy like you, Riley."

Sure, I stuck my tongue out at her for that, but she was correct. Not a lot of girls without augments can do the things I could do at that age. Which is a real shame! I think everyone should experience being filled up that much at least once in their life. It's a lot of fun! But I'm getting side-tracked again.

Our hunt for Dana was entirely unsuccessful. We searched the junior playground, including all the good hiding spots for Hide'n'seek. We looked all over the big kid's playground, behind the classrooms, even inside the sports shed, but we couldn't find her at all. I even thought to check the toilets, in case she was using them - with cum-loads like hers, I thought for sure she was probably relieving herself in the sex toy there, or maybe masturbating into one of the actual porcelain toilets. We didn't find her, or even a suspicious trail of excessive cum to follow. Though, I might have been a bit distracted by the resident sex toy. It occurred to me that she said she would be there in the program on Friday, but I hadn't seen her at all.

"Oh, yeah! Silly story, that!"

We had managed to get a moment to speak to her without anyone coming in to use her body. Lying on her back in a pool of cum and waste, I straddled her thighs and gently fingered her urethra - I was fascinated by how she didn't even react when I shoved my fingers inside there. I could still barely touch inside mine without twitching wildly.

"I was all lined up to help out in the class, but it turned out that there was another sex toy already assigned! I thought it was just a mix-up of days, and that I was meant to go to the basic class, but not that one either!" The sex toy laughed freely even as I hooked both of my thumbs in her urethra. Pulling, I managed to tug the tiny hole open wide - wider than I'd ever pulled open any of my holes. She didn't even flinch, even when I wiggled myself into position to start peeing into her bladder.

"Then, what happened?" Yvee was sitting nearby, on a nice clean bench - she didn't want to go anywhere near the mess around the sex toy.

"Well, turned out they didn't have anyone else to replace me here in the toilet, which is what I thought was going to happen. Normally you get to go to different spots, but I've just kinda been here in the school bathroom the whole time! Would be nice to maybe get tied down to a relief post in a public park or something."

"Don't you get to go home to your mummies?" Once again, Yvee looked confused. I perked up too, my golden stream slowing down even as her bladder filled.

The sex toy shook her head and smiled. "Nope! This is my home, here in the bathroom! It's open to the public at night, so someone has to be in here at all times."

I frowned at that. When I become a sex toy, I wondered, will I be stuck inside one place forever? The thought of not getting to go home to my comfy bed, to my mummies and my sister, that felt a little bit sad.

"Don't you miss your mummies?" I let go of her urethra, and watched in surprise as it closed right up to a hole no wider than my pinky.

"They come and visit me all the time! Mostly to use me after work, but I get to see them. And this is where I went to school, so I'm extra lucky to get to have my school friends use me too!"

My worries washed away, as simple as that. That made so much sense! I didn't have to be away from everyone I loved, they could always come see me! I looked over at Yvee, but she just gave me a funny look. I turned back to the sex toy.

"How'd you get your yoo-reetha so stretchy?" I asked, poking a finger into it again.

"Loads of practice!" She shot me a wink. "Well, that, and body mods. But even with body mods, you still need to practice a bunch! Don't worry, once you get yourself an upgrade and a bit of time on the stretching machines, you'll be a pro! ... Go on, put your hand inside."

"My hand...?" I raised my eyebrows as I looked at my little fist. She gave me an encouraging nod, so I went along with it. The one finger in her hole was joined by a second, then a third and fourth. With a tiny bit of wriggling, I shoved my whole hand inside, her urethra squeezing tight around my wrist as I sloshed my hand around in her bladder. "Woah!"

"One time," she leaned forward, as though to tell me a big secret, "During one of the training camps near the end of my training, I managed to get an entire-- mmph!"

Unfortunately, one of the bigger girls had taken that opportunity to swing her leg over and slide her cock down the sex toy's throat. I got the feeling from her slow, casual throat-fucking that she was going to be a while, so I would have to wait to hear the end of that story. I pulled my hand out of her bladder, a splash of my own pee bursting out all over my belly as I did. I simply couldn't wait to be as stretchy as she was.

At home, our casual sex attitude was infectious. Mummy and Andrea passed me around like I was an object more than a person, and both made a habit of using me without warning. Much to my annoyance, however, they never used my urethra.

"Sweetie, I love you very much, but you're just not able to handle it."

Mummy had just finished painting my womb white with her cum when I had demanded to know why she hadn't tried my urethra even once that week.

"I can handle it! I took aaaall of Dana's cock, and her cum too! I was a big balloon, and it felt super good! And yoo-reethas feel super nice inside, so... you should put your cock in there." I grabbed my mum's penis and stroked it, trying to get her hard again so she could fuck my peehole, but she took my hand away.

"Riley, you passed out for six hours, and wouldn't stop shivering until we got all of her cum out of your bladder. You can do some amazing things with your pussy and your butt, but I think you need some more practice before we can use that hole for sex, okay?" My mummy stroked me on the head, giving me her nicest smile, but I was still grumpy.

"I can do it. If I got body bods."

Mummy gave a quiet snrk. "Body mods. I think it's a bit soon to start with those. Remember the painting supplies...?"

I did remember them. So many paint pots unopened and unused... I gave a sad little nod. "When I do weally good at the program, can I have some?"

She smiled a big smile at me. "Alright, I'll talk to Mama about it. No promises, okay? Mama still has to say yes!"

Classic Mummy, believing that Mama could ever say no to me. She always doted on Andrea and I... and that was before I could show Mama how much I loved her with my body, too. Those body modifications were as good as mine!

Speaking of Mama, she came home from her business trip that Wednesday. I didn't know she was coming home that day, or I would have been intolerably excited. I did find it suspicious when my mum didn't pound me the moment we got in the door, and instead ushered me into the lounge room. Sitting on the couch with a big grin and fancy paper bag from a store I didn't recognise was my mama. Mummy gave a huge smile too, and waved.

"Can't believe you got home before we did, Fiona!"

Where mummy was short and curvy, mama was tall and slightly athletic. My sister Andrea took after mama like I took after mummy - Mama had long, straight blonde hair that came down to her hips, and bright blue eyes. Her breasts were smaller than mummy's but still nice and soft, with big perky nipples and wide pink areolas. Between her legs was a sight I'd been waiting eagerly to see since my examination - her cock wasn't super long compared to most dicks in our world, about 7 inches long, but it was very thick. Twice as thick as mummy's, and easily thicker than both of Andrea's. That extra-thick cock was at half-mast, as though quietly waiting for me to be ready.

"Mama!" I ran towards her and jumped into her arms, letting myself be pulled into a big bear hug. Mummy squeezed in and joined me, wrapping her arms around both of us and kissing mama.

"Good to be home, Gloria. What's this about our little girl wanting to be a sex toy?"

Mama picked me up by the waist and span me around upside down, wiggling me this way and that as she clowned around, pretending to inspect me closely. I giggled, and wriggled in her grip.

"Well, someone saw a super-cool sex toy on her first day of school, and blitzed through the examination... Now this little rascal is obsessed with it!"

Mummy tickled me, which just made me wriggle and giggle even more.

"Woow, really! Well, it's so lucky that I just happened to get a gift that's perfect for a sex toy!"

Mama let me go, and I flopped into her lap. Sitting up, I straddled her legs and let my hands wander to her cock. Mama raised an eyebrow at that. "Really is eager, isn't she?"

"Yep. You better show her that present, and fast."

Mama nodded and reached into the bag next to her. From it she grabbed a plastic box. When it became clear I didn't know what it was, she snapped it open ... and then laughed when I still didn't know what the contents were.

Inside was a variety of little rubber balls on strings. There were three strings altogether - one with lots of small balls, one with just a few big balls and one that had the balls get bigger and bigger the further down towards the stopper they went. Each one had a little stopper on the end, a wide flat piece that could be popped open to access a little dial.

"They're vibrating beads, Riley. I honestly thought you'd know what they are. You didn't see any in your training?"

"I only did one training, and we practiced with our yoo-reethas." I pointed to my peehole to illustrate my point. Looking down just brought my attention back to Mama's cock, which was now rock hard against my belly. My hands went right back to idly stroking it.

"Wow, sounds intense. Wanna try these out, kiddo?" Mama pulled one out of its cradle in the plastic box, the small one with lots of beads.

I nodded my head, perhaps a little too emphatically after mama showed what they did when the dial was turned. Those beads turned from mildly interesting to I need them inside me this instant the second they started buzzing.

My mums laid me out on the couch. Mummy had me lie on my tummy, with my head in mama's lap and my butt poked up in the air. A cushion under my tummy helped me get comfortable as mummy sat behind me.

"Which one goes where, dear?" Mummy held them up.

"Wherever you think would be the most fun. Hm, but save one of them for yourself, too." Mama gave a wink. "They're not just for Riley."

I would have whined and complained, but I was a bit too busy rubbing my face and lips against mama's fat cock. I couldn't wrap my hands around it, even with both of my hands trying together. I couldn't believe mummy could fit this thing inside her - I wondered if maybe it might actually be too big for me. For some reason, the thought of having it shoved inside was a bit scary, like my body could handle long just fine, but wide... my body shivered at the thought, and mummy hadn't even inserted one of the beads.

Behind me, mummy started with the smaller, longer chain of beads, sliding them one by one into my pussy. I was, as per usual, soaking wet at the very prospect of sex, so she didn't need any additional lubrication. However, the size of them felt almost disappointing, even as each one inserted pushed the rest of them further inside me. However, I wasn't disappointed for long. The beads just kept coming, one after the other. It felt like mummy would never run out of them, even after they pushed inside my cervix and began to fill my womb. More and more pushed their way in, until the ones inside my womb were forced to twirl around to form a kind of knot. By the time the rubber cap was pushed down over my pussy, I could feel the lumpy, bumpy beads sticking through my belly as I ran my hands over the skin.

"Okay, mummy's gonna turn them on now. Get ready, Riley!"

Whatever, mummy, I thought. Sure they're buzzy, but I'm the bestest sex toy, and I've had sex with huge cocks! These buzzy beads would never be as strong as those--

I yelped in surprise as the entire inside of my pussy began to vibrate. It wasn't anything like the pushing, sliding feeling of a dick or my fingers. It was like thousands of tiny, tickly tongues were licking super fast over every single surface inside me. I clutched onto mama tight, burying my face in her crotch as I moaned. My toes curled and my thighs shook with the unexpected pleasure. I had no other experiences to compare it to.

As the initial shock wore off, I decided that I loved the feeling. Not as much as having a cock inside me, or being used for sex or as a toilet, but I still loved it. The constant buzzing never let up, never stopped stimulating every part of me. I drooled everywhere, slobbering all over the base of mama's cock.

"Which one, honey? I just can't decide."

"Hmm... that one."

"Really, Fiona? I'm sticking these in her asshole, aren't they going to be a bit much?"

I looked back over my shoulder, still clutching onto Mama's thigh for dear life. Mummy was holding up the one with the different sized beads, and I realised how dreadfully large the final bead in the chain got. My estimate was that the last few were about as thick as Mama's cock, with the final one just a bit bigger. And they were going to buzz too? I gulped, honestly a little worried.

"Gloria, she'll be fine! If she's been as horny as you've been telling me, maybe this'll help her calm down a bit, hey?"

"Alright, alright. Here we go, sweetie! Tell me if they get to be too much for you."

"Mmngh." My grumbly voice was somewhat diminished when my whole body was quivering with pleasure. Horny five-year-old Riley just didn't get why everyone kept asking if she wanted to stop! A nice gesture, but the bestest sex toy never backed down from a challenge. Even if that challenge was having her ass plugged full of vibrating beads.

On the advice of mama, mummy grabbed a little bottle out of the bag and poked the nozzle cap into my butt. A little squirt of lubricant - not a strict necessity, our bodies being how they are, but it was useful for the sake of comfort. Ah, the days before I got that auto-lubricating mod...

Then came the beads. The first one was smaller than the ones that were still rocking my womb, but they quickly ramped up in size as the previous one pushed the one before it deeper inside. Mummy started them out vibrating this time, turning the dial so they gave a off a softer pulsing sensation rather than the harsh, constant vibration of the chain in my pussy. It gave a weird sensation like they were expanding and contracting inside me, and the feeling was like getting a massage inside my body ... well, while someone shoved a soft rubber cone up there at the same time. Halfway down the beads were easily as wide as most of the penises I'd taken up there, beating Andrea and Shay's cocks for thickness. A little bit further and they were bigger than the examiner and mummy's dicks. I hadn't exactly attempted to stretch out my butthole beyond the size of these insertions, hadn't realised what it would feel like as my sphincter was forced open only to attempt to snap shut over the other side of increasingly large, thrumming rubber.

It didn't take long to discover that the self-proclaimed bestest sex toy did, in fact, have limits. My asshole only opened so wide, and I gasped and clenched my whole body as a rubber bead barely made it in under my maximum stretching limit. Mummy didn't seem to notice, attempting to shove the next one in with the same slow, measured care as the rest. My constant drooling, moaning breaths transformed to gasps, and I involuntarily kicked out my legs in surprise. It felt like mummy was going to break my body!

"S-Stop!" I shouted the words I was sure I would never say. "My butt-- it's too big!"

Mummy stopped immediately, and I let my body relax a little bit. Just on the other side of the ring of my asshole was that almost-too-big bead, taunting me with the fact that I would have to take it out. The inside of my anus was more than willing to stretch to accommodate it, but the entrance just couldn't do it! I kicked my little legs, annoyed. I probably made a very silly noise.

"Riley, it's okay sweetie, I'll take it out--"

"No! I want it in!" I whined.

"Oh, I think someone's being a bit of a grump!" Mama flipped me onto my back to look up at her while she stroked my head. "You'll be able to get it in there, just not right now!"

"But... " I looked over at mama's fat cock, and nuzzled my head into it. "If I can't get it in, then I can't get Mama inside me either..."

It was mummy's turn to laugh. "Oh, Riley, sweetie! It took me a month of stretching practices before I could fit your mama's cock inside me! In fact, I'm shocked we got this much inside you. But, your little holes need a bit more practice before they're that good, okay?"

I blinked up at mama, one of my hands unconsciously sliding down to my clit to rub myself amidst the feeling of the still-vibrating beads. The gears turned in my brain.

"So... if I practice lots, I can weally fit mama inside me?"

Both of my mothers chimed in, nodding and smiling at me.

"You'll be able to fit a lot more than me in!" Mama smiled.

"Those free-use sex toys are crazy! I've seen them fit some crazy things inside themselves. You remember that one we saw at that one pub?"

"Oh, the young lady with the whole keg of beer inside her! Wow, that thing would be tough to lug around, but she had the tap sticking out of her pussy and walked around like it was nothing!"

I had no idea what my mums were talking about, frankly. But, the idea that hard work and practice could be converted directly into more new and exciting sex acts ... well, that clicked right into my head and never left.

After that incident, I kept the smaller of the three vibrating bead chains for use at school. It turned out it was a lot easier to concentrate on my school work when my constant libido was offset with a womb full of vibrating beads. But, it did get me quite a bit of attention.

Sitting cross-legged on the floor of my classroom on Thursday morning, Mrs O'Farr was having a bit of trouble getting everyone but me to pay attention to her lesson.

bzz-bzz-bzz-bzzzzz. ... bzz-bzz-bzz-bzzzzz.

"Whats that sound?"

"Is that your phone, Mrs O'Farr?"

"No, it isn't. Now, if you could just ignore it and look back up here--"

"It's coming from Riley!"

"... It's in Riley's pussy!"

All the kids on the floor gathered around, a small throng of curious, naked bodies piling in to see why Riley sounded like an ignored phone call.

"Riley," Mrs O'Farr sighed, "Your mum explained the situation, but could you turn it off, or at least down a bit while you're on the floor?"

"Sorry, Mrs O'Farr."

I flipped open the lid and turned the dial back to the lowest setting, the beads returning to a dull thrumming rumble within me. Everyone else looked either confused or amused, except for one girl I hadn't learned the name of yet.

"Is that a vibrator?!" She sounded shocked. "Those are for big kids!"

The clamor started again, everyone demanding to see. Mrs O'Farr clapped to bring everyone's attention back.

"You can bother Riley about it later, girls! Now, back to our book..."

Naturally, at recess time, I was swamped with people who wanted to see what it was. For some context, it wasn't unusual for girls my age to know what vibrators were, but it was for them to be using them - the excessive kind of libido that plagued teenagers meant that they were the target demographic for sex toys (of the non-living kind). It was super cool and grown up for someone my age to be walking around with a vibrator inside me, and I loved all the attention.

"My mama came back from a trip and got them for me, 'cause I'm gonna be a sex toy." I stood triumphantly at the centre of a small crowd of girls, nearly half my class, as all of them stared at my crotch. As if to prove how cool I was, I reached down and turned the beads up to their highest intensity. Big mistake. The sudden, chaotic buzzing made everyone jump, and made me groan and clutch at my belly. My legs shook with the intensity, and I turned it down just a little. "Th-they feel super good..."

"Can we see it?" A taller girl with a six-inch dick and long hair down to her hips squatted down in front of me. "Take it out, Riley!"

As everyone bothered me for it, I nodded and grabbed at the plug. I pulled them out quickly, the beads making a wet plip-plip-plip as my pussy opened and shut around them. The girls laughed and gasped and cheered as they saw just how long the chain was - they had all expected a single toy, the kinds of things their mothers and sisters would use normally around the house, not a big chain. As the last of the beads started to vacate my womb, I felt some of them knot up - I ended up dragging out a bunch of several beads tangled together all the way out of my pussy, all of them still shaking and vibrating. The girls took them, looked them over and felt them - I even spotted a few girls put them to their clits like they'd seen bigger girls do, yiping in surprise at the sensation. Then, with everyone's curiosity fulfilled, most of the girls left. I turned the beads back down to their low setting, untangled the knot and began sliding them back in me.

"Is it true that you're really gonna be a sex toy?" The long-haired girl from before had stuck around, and was watching me shove them back in.

"Mhm! I'm gonna train real hard, and be the bestest, and take the biggest cocks an' stuff!." Don't you wish you could have been this modest at age five? Small, realistic goals for Riley Evergreen. The girl certainly thought it was impressive.

"That's sooo cool! I'm Belinda, but you can call me Bee! Like a buzz-buzz bee!" She giggled and pointed at my crotch - it was most certainly going buzz-buzz, speaking right back to her.

I liked Belinda straight away. She was super funny, and even though she wasn't horny like me, she still thought it was cool like me! I really hoped I could introduce Belinda to Dana too, just as soon as Yvee and I found her. At the very least, I'd be able to see her at the program the very next day.

We three girls didn't manage to find Dana that Friday morning, either. We had surely scoured every single possible hiding place in the school, so the only idea we had was that she must have been hiding inside somewhere. At the very least, in all our searching, Belinda, Yvee and I all became closer friends! Because they were my close friends, I told them that they could use me to relieve themselves like they would use a sex toy. Yvee didn't take me up on the offer at the time - for some reason, she still preferred using the sex toy in the school bathroom, though she would happily use me to skip the queue. Belinda was interested, but I had told her too late - she had already been to the toilet, and girls my age didn't tend to need to be sexually relieved particularly often. I'm just weird and horny! Don't count me, I'm an outlier!

When it came time to head off to the program, I didn't need Amy to walk me down there. I took out my vibrating beads, shoved them into my backpack and headed down to the program room, eager to find out what debauchery we would be learning about today. When I arrived, it turned out I was the second person to arrive. Apart from instructor Mika and her assistant Amy, the only other person there was Dana.

"Hi Dana!" I waved, jogging over. Dana was sitting on one of the chairs, her belly bulging slightly where the chair-mounted dildos were pressing against the inside of body. Her three cocks were at half-mast, gently oozing cum as their owner did her best to grind her butt against the chair. When she heard me, she looked up as though surprised to see me.

"R-Riley! You're okay! I'm so sorry!"

"Sorry?"

"A-About ... f-flooding you. I th-thought you were h-hurt."

I shook my head, put my hands on my hips, and adopted my best superhero pose. "No way! I just have to practice harder to be strong enough to take all your cum again!"

Dana looked a bit more shocked, her eyebrows spiking up even as her cocks all sprayed a gout of cum. A fair bit splashed on me, warm and fragrant as it dripped down my flat chest and over my belly.

"Wow, little Riley's back!"

I turned around to see the older girls, the one in the middle of their group beaming brightly at me - that was Cleo, I think. The three girls were very similar in appearance, with brown hair, fair skin and brown eyes, so I had a bit of trouble telling them apart. Cleo was a bit shorter and pudgier than the others, with heavy balls that hung low and swung around when she walked. I gave her a wave - she responded by walking over, picking me up and hugging me like a doll.

"Ah, we all thought you were a goner!" Looking over Cleo's shoulder I spotted Fey - slightly bigger dick than the rest, and budding breasts with very large nipples - who gave me a pat on the head. "Amy had to squeeze you out into the pool - splooosh, you sprayed out everywhere!"

Kim, the other of the trio, also gave me a pat on the head. She was a bit taller, slightly bony with a cute face. "We're happy you came back. I think Dana would have been really sad if she scared you off of being a sex toy."

Cleo put me down and I turned back to Dana. She looked down and away, shyly agreeing in her own way.

"Well, no worries!" I adopted my signature pose once again. "'Cause I'm Riley Evergreen, the bestest sex toy ever! An' I'll take on anything, and get stronger and stronger!"

The trio of girls gave me a little clap and more head pats as they made for their seats - Instructor Mika was hurrying everyone up. I took my seat too, right next to Dana at the front of the class.

I realised that, due to what happened last time, I hadn't actually sat in one of these seats yet. The two rubber protrusions weren't particularly large, but they were about as thick as my mummy's cock, spaced just so that one could be in your ass and one in your pussy. I had to squat on the seat to line them up first, but sliding myself down onto them felt great. They had these little nodules that sent tingles up my body as they entered me, and the simple feeling of being full really helped my concentration. In hindsight, that's probably why they were there - how else were you going to get a classroom of horny little kids to concentrate unless they could quietly fuck themselves on their seats while listening?

"Hello again, girls! Glad to see you're all back after last week!" Mika gave a big belly laugh, looking over at me. "Normally we have our lesson on urethral penetration first to scare off anyone having some doubts, but I'm doubly impressed that everyone's back after Riley got carted away! Don't think I didn't hear you say you'd take on anything, Riley! We'll be sure to test you on that!"

Everyone gave a laugh, except for Dana - she still looked like she was sorry about it, though every reference to the matter caused a spray of cum to blast out of each of her cocks. The very memory of it made her dicks remember how much fun it had been to turn me into a cum balloon, it seemed.

"Today's lesson is two-fold!" Mika held up two fingers. "First, you're all going to listen to some interesting facts about all the different things that a free-use sex toy might be used for. Second, you're all going to spend time with some stretching toys."

"Mika thought it'd be a bit boring if you just got talked at for a bit." Amy rolled a trolley up to the front of the classroom. "So, we decided to combine it with a stretching session!"

From the trolley, Amy pulled out nine ... thingies. They were dome-shaped thingies with some buttons on one side, some platforms on the side with straps, and a bunch of holes across the top.

"Who'd like to get on the first one to show everyone how it's done?" Amy gave a look around. "'Cause, I could get on one, but I'm already waaay stretchier than you guys are - guaranteed!"

"I'll do it!" Cleo stood up and waved. She made her way over to the front. Amy instructed her on how to get on it - the platforms on the side are for kneeling on, so your legs are spread nice and wide over the top of the dome. Amy strapped Cleo's legs down, and pulled an extra strap out to bind her arms back behind her back.

"Why're we tying my arms up?" Cleo looked back, unconcerned.

"It's quite common for sex toys to be 'installed' in places, which means you'll be tied up and completely unable to move." Amy knelt down and started pressing some buttons. "This is to get you used to being unable to do anything about someone stretching your pussy to its limits, of course!"

After a couple more button presses, the TV screen behind Amy and Cleo changed to a completely different view - it was a camera feed of Cleo's nethers! Everyone began to murmur in surprise, though I was rather starstruck by the sight of her soaking pussy and slightly-dripping asshole. A bead of white sliding out of her hole insisted that she had been just as eager to let others use her as I had been, though with some more success on her part. Cleo could see the TV too, as Amy swiveled her around - she looked really excited.

Two mechanical arms slid out of the dome contraption, clear rubber hooks on the end sinking into her asshole. Everyone immediately knew what it was going to do, and the room tingled with excitement. I watched the TV screen intently as the arms moved away from each other, stretching Cleo's asshole wide. It quickly brought her to as wide as I was used to taking things, then a bit more, a bit more ... the ends of the mechanical arms slipped further inside, expanding the inside of her poop chute so that we could see everything inside. Cum drooled down her inner walls, though I was a little disappointed to see that there was no poop up there.

Another set of arms did the same as the first, spreading Cleo's pussy-lips before slipping further in and pulling her wider. It didn't take long for us to be able to see deep enough inside to stare straight at her cervix.

"There's another hole in there!" I didn't actually know anything about anatomy then, though I had a feeling there was something like that in there.

"That's right," Mika smiled. "That's her cervix. We going to stretch that open too, Cleo?"

"H-Huh?" Cleo looked a bit distracted as the arms pulled her wide open. She wriggled a bit against her binds, not uncomfortable or in pain, but squirming all the same. "S-Sure?"

"How about we get everyone else set up, first?" Amy looked over at everyone else, her fat cock growing hard. She looked down at it, suddenly remembering something. "Oh, and we will be stretching urethras too! Those holes are just as important as the rest, girls!"

It took a few minutes, but Amy got us all hooked up on the machines. We could all see the TV, which was now showing a rotating camera feed of each person's holes from between their legs. It was a little hard to tell people apart by their crotches, but mine was pretty distinct - the cute, tiny pussy of a five year old, fair skinned and without Dana's hefty balls, it didn't take a genius to track that one back to me. My mouth watered at the display, but my attention was quickly grabbed (almost literally) by the poking of several rubber hooks. Mechanical arms unfolded from everyone's machines as Mika controlled them with her computer, and each of us had our pussies and assholes pulled open to their comfortable limits. To my surprise, my holes were the least open of everyone's, even Dana's! Everyone was stretched open wide enough to fit a fist inside them at least, but my body refused to open up any wider than I'd already tried to make it go, at least around the entrance of each hole.

Another button press from Mika, and the little arms hooked into our urethras - the lower ones on our vaginas, for all the intersex girls with multiple. At the same time, more arms reached up inside our held-open pussies and grabbed at the entrance to our cervix. It was so cool to see inside everyone's wombs, and I loved seeing inside my own. Everyone's holes being opened unleashed small waves of cum, pee and poop that Amy dutifully cleaned off the cameras, but there was still plenty inside us. I could see the inside of my own pussy was slick with semen from where my mummy and sister had used me that morning, and thinking about that got my mind off the bit where the machine was trying to pull my holes open even wider. I squirmed like crazy as the arms pulled open my urethra, my pee simply falling out as my bladder was opened up for me. Within a matter of seconds the machines had all made us leave a wild mess all over the floor. Thank goodness we didn't have to clean up after ourselves today!

"Okay, while those are stretching you, time for ... Free-use Facts!" Mika waved her hands out wide, and some of the girls gave her half-hearted claps - we were all still adjusting to the fact that all three of our lower holes were being stretched wide open.

The girls with cocks were also looking down with some concern as several sets of mechanical tentacles snaked up their lengths and began to clasp at the heads of their dicks. I looked over at Dana as her dicks were gently pulled open, each hole opening up wide enough to fit a dick inside of. A constant stream of cum was pouring out of her as the rubber-tipped machine tentacles slid further inside her, extending the stretch from the opening down further and further.

"As you girls probably know, free-use sex toys are everywhere!" Unconcerned by the amount of squeaks and moans the machines were producing in us young girls, Mika carried on. "You've probably seen plenty of them in shops and bathrooms, maybe even on the streets ..."

Now, I don't remember word-for-word what Mika told us, so I'll just give you my explanation! After all, I am something of an expert on the matter. However, my list of roles for girls turned sex toys isn't exhaustive - there's always clever people out there finding out new and exciting ways in which a living onahole like me can be used to please someone!

The most obvious use is as a general-purpose sexual relief tool. Sex toys are usually in bathrooms, shopping centers, busy street corners and parks, all the kinds of places where lots of people would go. It's the most common role for a sex toy, and the one most people normally see. If a woman gets a hard-on, she doesn't want to walk around knocking things over with her erection - instead, she'll seek out a nearby set of holes and pound them full of cum. Some places strap their sex toys in, just to ensure people don't wander off with them. It's not uncommon for women with particularly large erections to accidentally (or intentionally!) walk away with a sex toy still on their cock, taking them with them.

Those same sex toys often work as toilets, and it goes without saying that regardless of a sex toy's current role, she is also available to be used as a toilet and cumdump. One of the standard body modifications available to a sex toy is to be able to subsist entirely off of cum, pee and poop, and anyone dedicated enough to becoming a sex toy absolutely prefers it this way. Just thinking about eating a fat, juicy log has my stomach rumbling! Of course, you don't need to use a sex toy's mouth as your toilet - you can just as easily poop or pee into any of her holes if you so desire. Some people even like pooping into sex toys so much that they'll line up their assholes with a sex toy's butt and request that the sex toy pushes her log right back the way it came so they can poop it out again!

Then there are active sex toys - ones specifically instructed to search out people in need of relief and do whatever it takes to relieve them. This is common in places where people can't move around very much, like in hospitals or cinemas. Some restaurants employ them too - simply wave down a sex toy like you would ask for a waitress to take your order, and she'll get right to pleasuring you! Active sex toys are really dedicated to their work, so if they're not needed anywhere else it's perfectly acceptable to ask them to suck your dick as hard as they can until you get tired of it. They're more than happy to spend several hours choking down just one person's cock, if that relieves them!

Back in the classroom, I was starting to get used to my holes being so wide open. However, every time I got used to it, enough to relax a bit, the arms sensed that and pulled me open just a little bit more. The feeling was so strange - it felt so good every time I managed to get a bit more open, with the feeling dulling each time. On the TV screen I saw that my little womb was completely exposed to the air. If my arms weren't bound behind me, I might have just tried to reach my hand inside there - to find out what was in those two little holes I could see in the back of my womb. Could you have sex with those, I wondered? Oh, little Riley of the past. Of course you can. Where there's a horny will, there's a horny way!

The last few sex toy definitions were ones I'd totally heard of and even used by that point. The next few were rather more obscure.

Next was a role known as a breeding toy. Sex toys with enhanced pregnancy capabilities, they were made to bear children for all sorts of reasons. From acting as surrogates for those who didn't want to have babies to acting as a different kind of sexual release, a breeding toy often had many special modifications. Speed was a common one - all breeding toys could give birth much faster than normal people, and some extremely modified girls could give birth within days of being impregnated. Some could even be impregnated in non-standard places, like bearing a child within a sex toy's breasts, bladder or balls. To my surprise, breeding toys could even be used with animals, and it was fairly common for farms to have one breeding toy on hand just for making more livestock! To be honest, at that point, I hadn't even considered having sex with animals. It made sense to little Riley - animals needed relief too, after all.

There were many other roles that didn't require big long explanations. Dispenser toys that made especially tasty cum and waste inside themselves to serve special restaurants, girls who were stretchy enough for grown adults to put their whole bodies inside to comfort them with their warm insides, even girls who were pushed to their limits as pleasing art displays. At that moment I could empathise with those girls made to hit or exceed their limits.

The machine underneath me had absolutely no mercy. Mika's explanation began to turn into background noise as the minutes turned to hours, all of us being stretched further and further on these machines. Amy came around to each of us in turn as we were stretched, making sure we weren't at risk of injury. Mostly though she slid her fingers and hands inside each of us to tease us more - my holes twitched and I groaned in orgasm as Amy slid her hand completely into my asshole, stroking the inside lovingly. I watched as she did the same to Dana, and shuddered in sympathetic pleasure as Amy slid a hand into one of Dana's cocks. I could see Amy's fingers pressing out from inside even as Dana's other two cocks sprayed copious amounts of cum all over the sex toy assistant.

Eventually, the day's program came to an end. All in all, we had all spent three hours strapped to the machines - when Mika turned them off, all of our holes hung open wide. I was worried for a bit that my pussy would never recover, but even a few minutes later I could already feel my body fixing itself right up. It turned out, as I learned much later on, that the same super-wonderful ability of my body to handle all these crazy insertions was also the reason why I was so bad at stretching out - my body was just way too good at closing up again! However, the stretching session had permanently expanded my abilities - and that was only the first!

While we all recovered from our stretching, I spoke to Dana.

"Hey, Dana," I gave her a hug, feeling her cocks press against my belly. "Where do you go at play time? I wanna show you my friends! Are you hiding?!"

"H-Huh...?" Dana shook her head, hugging me back - it just felt right to press our bodies together, even if we were having a conversation with our lips nearly touching.

"We looked everywhere! Where do you hide?"

"I don't hide." She seemed a bit annoyed. "I'm... always in here. In the program room."

"... YOU CAN JUST COME IN HERE?!"

I hadn't meant to shout, so I said sorry to Dana's poor ears by giving her a kiss (and also by actually saying sorry).

"Y-yeah ... Riley, they said on the first day, but ... you were ..."

Dana frowned, so I kissed her again - this time, sliding my tongue into her mouth like mummy showed me. "It's okay! Just 'cause I got beat the first time doesn't mean I'm sad! It was so super duper fun! I can't wait to do it again some time, okay?"

Dana looked at me, as though trying to figure out if I was lying to her or not. When she figured out I was telling the truth, she smiled right back at me.

"Girls!" Mika called out to us. "Your parents will be here soon - how about we have some fun while we wait?"

Both of us looked up to see Amy and Mika presenting their cocks. They didn't need to explain themselves as they each put a hand on our head - Amy's hand on mine, Mika's hand on Dana's - and pulled our lips to the tips of their dicks. We filled our bellies on a nice warm treat of cum and pee, holding hands as the instructor and her assistant treated our throats as little onaholes. We even swapped places, Dana and I getting to try out being used by both of them.

I could not wait for the next week. I was going to bring Yvee and Belinda in here - into the program room! Then they would be able to meet Dana! Even with a cock down my throat I was already planning out how exciting it would be! Maybe I could convince my friends to have a bit of fun like this? With Dana's three cocks, we could each have one to ourselves...

"Oh, Mrs Evergreen!" Mika called out, still sliding me up and down her cock. "Just one moment, and she's all yours."

Mika grabbed my hips and picked me up into the air. I hung there, the tip of her dick in my stomach for just a moment before she began to rapidly pump her hips back and forth. Rapid-fire piston fucking of my mouth brought out the desired effect, and my stomach got a nice new load of delicious seed. Mika pulled out while she was still cumming, splashing the inside of my throat and mouth on the way out and spraying my face and chest with it too.

"C'mon Riley," Mummy took my hand. I looked back.

"Bye Dana! See you on Monday!"

My school life was getting more fun every single day.

Chapter 5: A Sex Toy Gets To Do What?!

Summary:

Hi! Riley Evergreen here! So, it turns out that there's way more to being a free-use sex toy than just having sex with people and being a toilet! For every single way there is to relieve yourself with a sex toy, that sex toy has to practice and become a professional at doing it. Oh man, was I ever surprised ... I hope you will be too!

Notes:

Hello, loves. I'm planning to make things get a little bit more hectic! If you've stuck with me this far, you may well enjoy what I'm going to have happen next! Or maybe not, and that's fine too.

I'm also debating whether to get some other ideas out in the form of new stories, and wheel back to Riley's adventures. Tell me what you think!

Chapter Text

Monday morning, recess time. Yvee, Belinda and I stepped out of the classroom with the rest of our class, but this time we had a mission. I was going to introduce them all to Dana, even if it meant dragging them to the Sex Toy Program Room ... and hey, little Riley of the past reasoned, maybe they'll have some fun while we're there?

So, we went. Belinda was practically vibrating with excitement - someone had grown a little bit hornier from sheer exposure to the world's bestest sex toy (in training (in training)), and she excitedly told me that she had started masturbating over the weekend and was greatly enjoying it. Yvee had no such change of heart, but she hadn't complained when I said where we were going, so I had the feeling that I was starting to get to her. I knew I would never quite get them to become sex toys with me, and that they probably wouldn't end up in the advanced program with me even if they did, but a girl could dream!

A few teachers watched as as we walked inside - good little girls like us were meant to be outside playing, but the sheer confidence of my stride (or maybe the pussy juices pouring down my thighs) gave the teachers a pretty good idea that I knew where I was going. I pushed open the door to the program room and let my friends walk on in.

The place smelled like sex ...which wasn't exactly unusual, given the nature of the room. But, it was recent sex. I could tell this with my refined sex toy senses, or maybe the loud plap plap plap sound and the fact that I could see it gave it away. Amy, the sex toy assistant instructor, was face down and ass up over the edge of the oversized bathtub at the back of the classroom. It was thankful she was side-on to us, or I wouldn't have been able to see her - a set of testicles the size of exercise balls hung over her legs as their owner clutched on for dear life, her tiny hips a blur. Dana was in the midst of relieving herself, her horny self entirely taken over. She clutched onto Amy's backside with her thighs, her three cocks sliding merely inches in and out as she jack-hammered away. One of her hands gripped Amy's hip tight, while her other held the sex toy's long ponytail like the reins of a horse.

"Ffffuck! I'm gonna fuckin' cum! Gonna make you a balloon of my seed!" Dana's normally timid voice was gone, though no amount of dirty growling could make up for her cute five-year-old pitch. "Take it! Take my cum! Ffffuuuucccckkkk!"

I certainly hadn't planned for this to be everyone's introduction to Dana, but Yvee and Belinda watched in stunned silence as the girl's balls pulsated. Liters of semen poured through her long, thin dicks, and Amy's body began to inflate. Underneath her, Amy's dick began to throb before a torrent of seed burst out of her. I was momentarily confused, until I remembered how intersex girls' bladders worked - all their urethras were connected, meaning all the excess jizz in Amy's bladder was being forced out of her dick as though she was peeing! It was very shortly followed by a similar torrent out of Amy's mouth and nostrils, her belly overflowing. All the cum in her womb that couldn't escape bloated her out until she looked ten months pregnant with twins.

All in all it took three minutes for Dana to finish cumming, with Belinda and I masturbating the whole while. Even Yvee started touching herself, but she was at least trying to be subtle - while Belinda was three knuckles deep in her cunt and jerking on her cock, I was taking the opportunity to practice my urethral insertions, using my middle finger to tug at the inside of my bladder as I rubbed my clit. When Dana finished, her balls were returned to their usual size, and the bathtub was filled to the brim with her seed. The room was flooded with the scent of her cum, a rich, heady scent that made me weak at the knees. All I wanted to do was throw myself in there and chug down every last drop! So I did. ... Well, I didn't drink the entire thing down, but I did hop into the tub.

With a little splash I slipped in beside Amy, my body shivering at the warm tingling feeling of Dana's cum. There was enough for me to sink up to my nipples in semen, and I could feel it soaking into my skin. Amy finished coughing up the last of Dana's cum and gave me a wave.

"Hi, Riley! Oh, you brought some friends with you!"

Despite the fact that Amy had just had an entire double-sized bathtub full of cum pumped through her, she was still completely fine. A real professional sex toy! However, Dana looked a lot worse for wear - groggily collapsed onto Amy's back, the sex toy had to reach back and pluck the tiny girl from her holes. Three foot-long cocks slorped out of her as she aimed her backside towards the pool, the cum in her bloated womb pouring back out to join the rest. Amy held Dana to her chest like a doll as the girl slowly woke back up.

"Amy, you're so super cool!" I was so impressed by the sex toy that I almost forgot my friends still standing there, touching themselves as they soaked in the all-encompassing scent of cum.

"I-Is that normal...?" Yvee pointed a shaky (and slightly wet) hand towards Dana. "Is she okay?"

"Don't worry!" Amy sat down on the edge of the tub, soaking her legs. "Dana has a special condition that makes it so she has to cum a huge amount every day. She'll recover in just a moment--"

"Agghhhhhhhh!" Dana made an awful squeaking noise and covered her face with her hands. Her dark skin made it hard to tell when she was blushing, but the girl was clearly mortified. "R-Riley! Y-Your friends saw me ... h-heard me ... n-now they'll think I'm ... I'm..."

"I think you're weally cool!" Belinda spoke up, taking off her shoes to join me in the tub. "Wooooah, this is so warm! It smells so good! I can't make this much stuff!"

"Oh, your socks are-- too late." Amy sighed, watching as Belinda's thigh-high rainbow socks became utterly soaked with semen. She stroked Dana's head, trying to encourage her, but the girl was already peeking an eye out between her fingers at Belinda and I. Then, her eye turned to Yvee.

Belinda, Amy and I also turned to Yvee. She was looking at us all like we were crazy. "That's ... that's so much!"

"You wanna hop in, Yvee? It feels super good." I looked over at Dana - she was very carefully watching Yvee's reaction.

Yvee looked unsure, but she was a clever girl - it took her a moment, but she figured out how sad it would make the cute little girl over there if she totally rejected her. Yvee gave a huff, took off her shoes and socks, and very carefully slipped into the tub with us. I greatly suspect this was the first time that kid ever even got cum on her, apart from maybe accidentally while using a particularly messy toilet - she still took to plunging herself in quite well.

"It... it feels ... not bad?" Yvee slowly let herself sit down, and I hugged into her side. I let my hands wander under the surface of the thick liquid, enjoying the feeling of Yvee's belly and thighs coated in cum. Surprisingly, she didn't stop me.

"You really like it...?" Dana pulled her hands away from her face. All three of us girls nodded.

"I told you, kiddo!" Amy gave her a pat on the back. "No one thinks its bad or weird! I bet you'll make an amazing dispenser toy, or ... well, probably a bathing toy!"

Dana looked up and gave Amy a smile. "You really think so?"

"Your cum is super warm and tasty, it smells great, and you cum so much at the drop of a hat." Amy gave her a hug. "You'll be the best dispenser!"

Little Riley Evergreen couldn't believe it. Dana was the bestest dispenser toy?! She just couldn't believe it! How could someone else be the bestest too?

"Oh my gosh!" I splashed my little arms, flicking cum everywhere. "Dana's the bestest, Riley's the bestest, we're both the bestest!"

I jumped up and threw myself towards Dana, scooping her up in a hug. My lower body dripped with Dana's cum, and I coated her with her own seed in the process. Even when they weren't erect, her cocks were still big enough and propped up enough by each other to rub against my clit even just in this simple hug - I resisted the urge to grind on her, mostly because I didn't think I could handle being turned into a cum balloon quite yet.

"Um," Yvee raised a hand like she was in class, "What's a dispenser toy? Or a bathing toy?"

Amy smiled, eager to explain. First, she scooped up a nice handful of cum and used it to lube up her cock, stroking herself gently - even if Dana had cum through her, I guess she didn't get to cum too. She looked at me, and I realised what she wanted.

"Want to do some practice while I talk, Riley?"

"Okay! Can we do it in the tub?"

With a bit of rearranging, Amy sat herself in the tub side-on to everyone, close enough that my friends could kick their feet up on her legs. Dana slipped into the tub next to Yvee, her body so small that she was covered all the way to her neck. Amy lifted me up, lined up my asshole with her cock, and dropped me down into a squat. Then, she let me go - I was the sex toy now, so it was my job to pleasure her.

"So, a dispenser toy is a special kind of toy who exists to make lots of cum, or sometimes pee, poop, or even milk! They get put into special factories where they're pumped constantly, day in and day out, to make as much stuff as they can."

Amy gently put a hand on my hip as I started to do squats on her cock. It felt great to have her cock up my ass, especially after having had to spend all morning without a dick in there. Whole hours without sex! Can you believe it? Dana's cum made an excellent lubricant, and I had absolutely no trouble taking Amy inside me all the way. I rested back against her flat chest, the slick coating of cum on my body allowing me to slide up against her body too.

"That sounds like what a cow does." Yvee looked a bit confused. "I saw it on a show, with the cow in a biiig place with lots of tubes and stuff attached. ... But why would anyone want lotsa pee? I thought only sex toys liked to drink it."

Amy closed her eyes for a moment, enjoying the feeling of me bouncing on her. "Weeeell, there's lots of people out there. Even people who aren't sex toys like to drink pee, or eat poop, or drink cum - hey, have you tried a taste yet? Then you'll know why people like it."

Belinda already had, but she took the cue to take another deep slurp from her hands. Yvee looked down at it, unsure, until she saw how Dana was staring at her once again. Belinda came to her rescue, though not in the way she expected.

"Hey, Veevee, I'll dunk my head in if you have a drink!"

Yvee looked at her and huffed again. "F-Fine. You'll look weally silly going back to class all covered in... cum."

With a blush on her cheeks, Yvee cupped a handful of semen and brought it up to her lips. She took a tiny, tiny sip ... and her eyes went wide. "W-Woah! It's ... weally tasty!"

"Isn't it?!" I called out, starting to pant from the effort of lifting myself up and down on Amy's dick.

Yvee nodded and slurped up the rest in her hands, chugging it down her throat as fast as she could. "It's like ... like ... nothing! I haven't had anything like it before! But it's sweet and slimy and amazing like a ... funny milk drink! It's yummy cock milk!"

Belinda giggled wildly. "Cock milk! Heehehehe, I think I saw that on a show! Okay, my turn!"

With a sudden splash, the girl dipped entirely under the surface. It was impossible to see her under there, except for the vague shadow of her body under that pearlescent, milky pool. We watched as she slid herself around, up Yvee's leg, until she found what she was looking for. Yvee yiped, blushing brightly as she pushed Belinda away.

"H-Hey! D-Don't lick my ... my... !"

"Your pussy?" Belinda, dripping cum from head to toe, licked her lips. "But it tastes extra good between your legs, Veevee!"

Belinda went down for more, starting a wrestling match between the two. In a matter of moments both of them were completely drenched with Dana's cum, and Dana herself was right in the splash-zone ... and smiling more than I'd ever seen. I barely even noticed as Amy painted the insides of my intestines white with her own seed.

"I didn't even get to finish explaining..." Amy sighed, letting me sit in her lap. "Oh well, maybe next time. Nearly time for you girls to go back to class, I think!"

Sure enough, the bell started ringing. I stood up, slipped Amy's cock out of my ass and turned around to give her a deep, passionate kiss. "Thank you for using me."

"Hehe, you've got good manners, Riley! Make sure you say thank you to Dana too."

I looked over at Dana. "Oh yeah! Thanks for making so much super yummy cum for us to play in!"

"Thank you!" Belinda, slipping out of her wrestling with Yvee, gave her a hug and hopped out of the tub. A pool of cum began forming around her feet as she dripped everywhere.

"Y-Yes, thank you." Yvee gave Dana a nod and hopped out of the tub too, similarly dripping. She wiped herself off with a nearby towel before putting her socks and shoes back on - Belinda didn't seem interested in wiping her mess off at all. I wasn't either! Both of us left the room as messy as could be.

Just as we stepped out of the door, I heard Dana ask Amy a question.

"... Who were those girls, anyway? Riley didn't say their names..."

... Ah well. Maybe next time, I thought. For now, the only thing on my mind was making my teacher very upset by getting cum all over the classroom with Belinda. When we walked back in, Mrs O'Farr just sighed and made us towel ourselves off, though nothing could be done for Belinda's drenched socks, or the cum we managed to get all over the other girls in our class as we hugged them. Poor Mrs O'Farr.

Side tangent, before I carry on. When I got home after school, I noticed that my skin and hair felt really nice and smooth. I couldn't figure out why it felt so nice, like I'd been washed with some really nice, fancy stuff. You can probably guess the answer, but five-year-old me did not know! After telling mummy all about what had happened that day, she had made a comment about how I got 'the fancy stuff' in my bath, and I thought at first that she was just being funny about having a cum bath. Later I found out why dispenser toys were in such high demand (and bathing toys - we'll get there!)

In my world, semen has a surprisingly wonderful effect on skin and hair. Most people's cum is equivalent to cheap soap or shampoo, and most people don't ejaculate enough on demand for it to be practical to wash their entire bodies and hair with it, but some people (especially people who ejaculate liters of cum at a time) produce high-quality seed that's really good for washing with. I don't remember the specifics - something something rejuvenation through sperm cell proteins or whatever - but it makes skin healthy and smooth, and leaves hair feeling glossy and full of life. When I found out, a little puzzle piece in my brain clicked together with another - I asked Yvee what brand of soap she used at home.

Yvee's skin and hair always felt so nice to touch, even if she didn't like how handsy I tended to get with her, but she loved getting complimented. So, after learning about the brand name, I looked it up when I got home. It was a fairly expensive brand, though as a kid I really didn't have any concept of how money worked (to be honest, I don't use money anyway, so it's a bit of a mystery all the same) but it definitely looked fancy ... and was packed full of cum. I guessed Yvee never thought to read the label, which promised the bottle contained '99% ejaculate concentrate'.

I also found out that the reason Amy and Dana had been in the bathtub was not to have a lovely cum bath, but because there was a special catchment tank underneath it that could be used to store Dana's cum. The school was selling the tanks full of semen to a local beauty products factory, and giving most of the money back to Dana and her family. Not even a full sex toy and she was already working hard! I was so impressed!

Anyway, back on with the show.

After the first couple of lessons in the Program Room, my life fell into a pretty stable routine.

Wake up to someone fucking me, have a nice breakfast with a side of my sister and mothers' waste, go to school, back home, have more sex. Every Friday, I practically vibrated with anticipation of getting to go to participate in the sex toy program. In class, I had convinced Yvee and Belinda to use me as a toilet over the normal one at the back of the classroom, though convincing Belinda to stick her dick into me was like convincing a cat to eat fresh tuna. Seeing those two use me got a few other girls interested, and before I knew it half of the class was using me as a toilet whenever possible. I usually ended my days with a heavy belly full of pee and poop, having spent half the day on my knees sucking on the urethras and assholes of my fellow five-year old girls.

The program days focused a lot on stretching, though there were plenty of other exercises. This meant that any time instructor Mika gave a theory lesson about being a sex toy, we all listened in while strapped into the stretching machines. After our first session on the stretching machines, our second started off with a declaration of our goals, with an amazing demonstration.

"By the end of this program, you need to meet a minimum stretching size or you won't be able to continue your training. These stretching machines are just the start of your exercises, girls!"

Mika punctuated her point by lifting up Amy and putting her down on a bench up the front. Amy laid back and spread her legs wide so we could see her crotch, moving her balls out of the way to expose her lower holes.

"As you all know, Amy here is an accomplished sex toy. That means she finished her training, the real training! That also means, her holes are very, very stretchy. Sure, Amy has some modifications, and you will all need some too, but she has put in a lot of practice."

Mika threw her leg over the bench, over the top of Amy, and sat down. Her thick cock gave a meaty plap against Amy's belly. I was a little surprised to see Mika actually sitting down on Amy's chest - the instructor was a lot bigger than skinny 12-year-old Amy - but the sex toy didn't seem to care at all. She really was something else! I couldn't wait to be that strong!

"Now, right now, all of you are stretched about this wide." Mika hooked two fingers just inside Amy's cunt and stretched it open. Shuffling her hands a bit she managed to stick two fingers on each side in there, sliding further in to reveal Amy's second entrance deep inside. Her pussy was held open almost as wide as Mama's cock was thick - which was a little bit wider than the stretching machine currently had me now. Everyone else, even Dana, was open that wide in all their holes - I was still a bit jealous of everyone else's stretchiness, but I knew I would just have to practice to get better.

"By halfway through the year, I expect all of you girls to be able to stretch this wide - in every hole! And that's a bare minimum, girls!" Mika's hands slid effortlessly into Amy's pussy, stretching it wide enough to fit both of her fists with space for a third. The gap was wide enough for me to fit my whole head in there. The thought of doing that made me shiver with excitement. Was such a thing even possible?

"However, by the end of the year, this will look like - excuse the expression - child's play. Ready, Amy?"

"Hm? Always. You know I'm way stretchier than the minimum, right? I majored in large insertions."

"Oh, really?" Mika looked a bit surprised. "Well, here I go then."

The instructor pulled her hands out and hopped off of Amy. Bringing herself around to the front of the table, and ducking down so we could all see, Mika slipped both of her arms inside Amy up to her elbows. Amy's belly bulged out, formless shapes molded around Mika's hands deep within her womb. Then, Mika wrenched her open.

The actual motion didn't seem to take much effort, and Amy didn't even flinch. I actually think it was probably a bit boring for her, especially in hindsight, after seeing some of the things that went inside her. Mika pulled Amy open, from entrance to womb, wide enough that I could have crawled inside. My entire body. Mika wanted all of us to be able to stretch open so wide that a whole five-year old girl could crawl inside our wombs! Then, I thought about it, my shocked brain playing catch up. It wasn't just our wombs Mika expected stretched that wide! Our assholes, our mouths, our urethras! Every dickhole in the classroom needed to open wide enough that a person could feasibly crawl inside! I was so shocked that I came on the spot, and a few other girls did the same.

"Th-that wide?!" One of the older girls was open-mouthed in surprise. "A-All our holes? Even... our dicks?"

"Mhm! Amy, do you mind if I show them?"

"Allow me, Mika."

Amy sat up and pointed her cock towards the older girls. She was the same age as them, her dick around as big - it was the perfect comparison for them. All of their cockholes were stretched open wide enough to take a dick inside, but it was nothing compared to what Amy did next. She hooked her index finger on both hands into the hole, then her middle fingers, then all four fingers of each hand, her thumbs gripping around the head. Then, she pulled. Her cock simply opened up, the thin slit of urethra completely exposed to the air. She kept pulling it wide and wider, until the size of the gap was about as wide as her shoulders. Everyone was silent with surprise at how casually she had done it, each of us vibrating with excitement.

After that demonstration, we were all extremely excited for stretching practice. We spent the first part of our lessons on the stretching machines while we listening to Mika talk about sex techniques - how to move our hips, how to use our tongues, where to put our fingers - and then spent the second half practicing what we just learned, or trying out weird and new exercises.

One of those weird exercises was 'continuous pooping' exercise. Everyone paired up together to sit on special reclining chairs facing each other, our assholes aligned with one another. I was paired with Darla, the eight-year-old girl with the big breasts. Though bras aren't exactly commonplace in our world, her boobs were each about a D-cup in size, and apparently growing. I had my feet up on her chest to help close the distance between us, my feet resting on her plush breasts.

"The point of this exercise," Mika explained, "Is to practice controlling the muscles in your bowels. Being able to relax and contract your muscles in there will make you far better at pleasuring someone with your anus! To practice, we're going to have one of you poop into your partner's asshole, and practice allowing it to go back and forth without breaking it."

It sounded weird, but it made a lot of sense - to do it, we needed to be able to carefully control when to push and when to open ourselves, or else we would smush the soft turd everywhere. We also needed to have a bit of a rhythm with our partner, which Darla and I quickly found out on our first attempt.

"Okay, I'll open up, and you poop into me, Riley." Darla hooked her asshole open, shivering pleasurably as my warm turd slid between us and into her anus. I still had my belly filled with my classroom's supply of poop, so there was no danger of us running out. When our turd suddenly squished up in the middle, we were both confused until Amy came to help us.

"If you both push at the same time, there'll be a problem." Amy reached in under us and cleaned out the offending lump, sticking it into her mouth with a smile. "Take turns pushing and pulling! Start off by waiting until you can feel like it's juuuust about to fall out of your body and stopping there. Then, when your partner stops, you know it's your turn to push!"

We both nodded and tried again. I squeezed out more of my rich chocolate, letting it slide deep into Darla's body. I felt it get skinnier and skinnier, and when I realised that I had reached the point where I'd normally let gravity drop my turd out, I stopped. Darla picked up the signal and began to push back. It was really weird to feel my poop crawling back up inside me, not quite pleasurable like a dick but still warm and exciting. I felt it slide up, way further than I expected, as I realised it had probably connected up with some of Darla's poop. With nearly a foot long log inside me, I felt Darla stop. Once again I let it go out, enjoying the feeling of relieving myself all over again. It was amazing! For about half an hour we all practiced, and Darla and I had such a good rhythm going that we were able to masturbate as we pooped back and forth.

A little over a month after I started school, two things happened almost back to back.

First, Mrs O'Farr had finally had enough of me bothering everyone.

One morning, my teacher pulled me aside and gave me a very serious look, though it was somewhat undercut by her ridiculously thick dick slapping against her belly with extreme arousal. I could almost guess what she was going to say.

"Riley, I know you've been asking the other girls in the classroom to use you like a sex toy. I need to remind you that being a sex toy is a lot of work, and that it will be very difficult to work hard in class if all your friends are treating you like one. But..." Mrs O'Farr squatted down, getting down face-to-face with me. "You have been getting your work done very well. If you weren't so set on being a sex toy, I could imagine you could go on to do lots of amazing things! You could be a scientist, or a doctor some day. Wouldn't you like to be something like that?"

"Nope!" I answered straight away. "I wanna be the bestest sex toy, Mrs O'Farr! And then everyone will have lotsa sex with me, even girls with biiiig dicks like yours!"

Mrs O'Farr's cock twitched as though it had heard its name called. "You really are dedicated, then. Okay. Riley, if you really want to be a sex toy so badly, and if you're okay with it, would you like to become the classroom's official toilet?"

I smiled, bright as could be. Before I could shout out yes, Mrs O'Farr put a finger on my lip to stop me. "That means that everyone in the class will use you, even me. I'm probably a bit too big to put my thing inside you, but I'll be relying on you to take my waste and relieve me when necessary. That's all day, every day, Riley! It's a big responsibility! Do you think you can do it?"

Mrs O'Farr's serious face made me stop and consider it. But there was really nothing to consider! The only problem with that statement was that Mrs O'Farr thought she was too big for me! Who did she think I was? I'm the greatest-- sorry, bestest sex toy there is! In training. I told her I'd do it, and she gave me a smile. A short while later, while everyone sat on the floor for the teacher to tell us what we were doing today, Mrs O'Farr made the announcement.

"Everyone, as you know, Riley is practicing very hard to become a sex toy. I know some of you are already helping her by letting her practice being a toilet, but I want you to know that Riley has agreed to become everyone's toilet! That means, all of you can use her just like you would a normal sex toy, whenever you like. If you need to pee or poop, you can do so inside Riley's body or on her, no matter what she's doing. Mrs O'Farr will be using her too! What do you think, girls?"

Everyone looked over at me, and cheered in delight. Some giggled, others chattered about it. Belinda did a very Belinda think by gently pushing me back onto the floor and sitting on my face. As a warm, fragrant turd slid down into my throat, Belinda cheerfully announced to the class that I was the best toilet ever, and that everyone will love using me. Unsurprisingly, my entire class was more than happy to take up Belinda's endorsement, and I went home that day with my belly thoroughly bloated out with everyone's waste. When I hopped in the car with my mum, I looked like I was pregnant. Most of them used my mouth, but there were quite a few who really enjoyed pooping or peeing directly into my womb or my asshole, and others who did so just because my other holes were taken. Sitting there in mummy's car, it really did feel like I had a baby made of poop inside me.

The second thing that happened was, upon returning home the next day with my body just as full, mama declared that it was time I got those essential body modifications in.

In our world, it's not hard to modify your body to do all sorts of things. In fact, it's not even that expensive! Being in the program, the school even paid for some of the smaller ones, so money wasn't a problem. Simple body mods didn't even need surgery, and could be installed very quickly - which is why we drove straight from school to the local modification clinic.

The receptionist at the desk gasped when she saw me waddle in with my belly full.

"I'm afraid we can't offer our full range of services for pregnant children, ma'am. You'll have to wait until she's given birth."

Mama laughed and ruffled my hair. "Oh, no, my girl's just a sex toy in training. She's loaded up with her classmates' waste. Which is what we're here about!"

The receptionist gave a small sigh of relief and a laugh too. "Oh, good! There's all sorts of paperwork I have to do when a girl that young comes in pregnant. You know, checks to make sure it was all consensual and all. Now, what were you after today?"

Mama and I went through the menu. There were loads and loads of different things I could do to my body. I could change the colour of my hair, skin, eyes, even insides to whatever I liked, though I didn't want to do that quite yet. There were modifications that would let me increase the size of certain body parts, like having a longer tongue or bigger breasts, thicker thighs, stuff like that. I could even have a penis installed, though it was a bit more of a process than Mama was willing to get done right now. I decided to save that idea for a special occasion, though it seemed like a really good idea.

What we were looking for was alterations to my digestive tract. Back when I had been examined for entry into the free-use sex toy program, the examiner had given me a special drink that had made it safe for me to consume large amounts of waste without getting sick, but it hadn't done anything for the nutritional value. As it was, if I kept coming home with my body stuffed with poop, I'd find it really hard to find room for real food, and that would make me sick in a different way. The obvious solution was, of course, to make it so that poop, pee and cum could be real meals.

"Oh, your school can pay for this one. It's on the list... ah, while we're here, how about that elasticity mod?"

Mama smiled down at me, but I just tilted my head in confusion. "What's that, mama?"

"The one that makes your holes stretchier than before. Your school is expecting you to get that one, so it's approved too."

My eyes glittered with excitement. Of course wanted the elasticky mod or whatever it was called! Then I would be able to stretch super super wide, and fit Mama's dick inside me with ease, and Mrs O'Farr's too - I couldn't wait to surprise her by giving her a blowjob to say hello!

After a bit of waiting, a doctor came to see me. She laughed when she saw me. "Wow, they weren't kidding. You really are packed full!"

"Mhm! I'm the class toilet!"

"Sheesh, they start younger every year, I reckon. They'll have pre-schooler sex toys before you know it! Now... Riley? I'm afraid we're going to have to have you empty yourself out a bit, or our special machines won't be able to help you."

The doctor helped me over to a toilet. It was a real toilet, to my slight disappointment, but I suppose a doctor couldn't practice messy living in her nice clean room after all. However, she did help me squeeze it all out, pressing in just the right way against my belly to push at my stuffed womb and bladder. Three separate logs slipped out of my body below me, and I shivered in orgasm at the feeling. It was like three cocks were constantly pulling out of my body, stretching me out as the doctor pushed hard on me. I could even feel the skin around my pussy and asshole pushing out around it, dragged with the flow - I didn't know what prolapses were at the time, but I really loved the feeling.

Once I was emptied out, the doctor put me into a special machine. My arms and legs were gripped by mechanical arms, holding me in the air spread-eagle. More arms came out, prodding at my belly as they made a strange whirring noise. I could feel my belly rumbling really weirdly as the machine changed my stomach and intestines to accept a new diet. Then, a set of rubber-coated tentacle-arms began prodding their way inside me. One slipped into my butt hole, another into my pussy and eventually my womb, and another into my bladder. A fourth one slipped into my mouth and began worming its way down my throat.

All four of them were weirdly warm, caressing my insides with an unusual tingling. They poked and prodded all over the inside of my body, going as deep as they could go to really press at every bit of my flesh.

"Now, while we're in here, we can make one additional change - free of charge, I might add!" The doctor talked to mama while she operated a little machine, sending the tentacles exploring deep inside me. "It's a matter of preference, mind you. We can also extend the elasticity to her fallopian tubes."

I had no idea what that was. Were there more, secret holes in my body that I hadn't found out about yet? Mama looked very interested. "Wow, I didn't even know you could do that. Uh, hmm! Riley? Does that sound good to you?"

"Mmhm!" I did the best I could to nod, what with the tentacle all the way down my throat. The doctor gave me a smile and pressed a few more buttons on her console.

I felt the tentacle in my womb shift direction a bit. Its tip pressed against a part of my womb that I didn't know existed - though, after thinking about it, I had seen those two little entrances when I got to see inside everyone's wombs, when we first started using the stretching machines. I could tell it was trying to enter them, and after a few minutes of that warm tingling feeling the tentacle managed to worm its way into that new hole. It felt really strange. The moment it was inside, I started cumming, and didn't stop until the tentacle removed itself. It was like pressing a button that said 'orgasm' - I could barely think while it was in there! It did the same on the other side, my drool splashing out around the tentacle in my mouth as it wormed its way into my fallopian tube as deep as it would go. Little did I know, I had set myself up for some really fun times later on.

After the whole procedure was done, the doctor let me out and gave me a lollipop as a treat for being so good.

"Never seen a girl cum from having her fallopian tubes enhanced," the doctor grinned. "Glad I got that procedure recorded."

"Recorded?" Mama looked confused. I didn't mind being recorded, but Mama seemed to.

"Oh! Sorry, weren't you informed? Part of the deal with the school paying for it is that the procedures are recorded for training purposes. Though, the footage is also available for purchase for those who just want to see a five year old girl get probed in all her holes with tentacles." The doctor gave a wink. "You can opt out of it being used, if you like."

"Ahh, no, it's fine." Mama shook her head. "I don't think Riley minds some strangers getting some relief out of seeing her body, does she now?"

I nodded. I hadn't even thought of that - just a recording of me could help relieve someone? So cool!

When we left the clinic, I hugged mama extra tight.

"Thank you sooo much! I feel so good inside! ... Hey, I bet I could fit lots of things inside now!"

"Yeah?" Mama smiled, picking me up in a princess carry. "Like what?"

"Like ... my hand!" I reached down and, without hesitating, pushed my hand into my pussy. "W-Wow! It's in! It's in, mama!"

I wiggled it around, feeling the inside of my pussy as I made a bump in my flesh. I pulled it out, and shoved my slick hand into my asshole. It went in just as cleanly as last time - I really had been made extra stretchy!

"Well," Mama gave me a big grin. "Looks like when we get home, someone's going to need her belly filled. And I've got just the thing for it."

Mama set me down and straightened up. I looked straight ahead, my eyes level with her thick cock. I drooled, shaking with anticipation. Finally, Mama was going to fuck me.

Chapter 6: Pregnancy Practice

Summary:

At long last, the part where things really start to heat up! With my body modified, I've gone from barely keeping up with my stretches to being a true stretch queen! And now, my sweet reward - sex with Mama! I can't wait to see what other things I get up to, now that width is hardly an issue. Well, unless something truly massive comes along. But that wouldn't happen *yet, would it? ... Well, I know what happens. But you'll just have to find out! Enjoy!

Chapter Text

Mama drove me home. The whole ride back, I was a dripping wet mess. I couldn't stop shivering with anticipation, my heart pounding in my chest every time I looked over at mama's thick, hard cock. Her heavy balls, full of delicious cum, were working overtime just to get ready to fill me! Those balls were where I'd come from, after all - one little sperm that ended up as Riley Evergreen, ready to get filled up with all those potential sisters. I distinctly recall dwelling on that statement on the ride home, and the short trip felt like it took an eternity.

Tangent time! I know you love them. As you're likely very well aware by now, we don't have an 'age of consent' or anything silly like that. Anyone can consent! In our world, there's no real risk of harming someone smaller than you, unless you're really specifically evil, but people here are nice! Yes, all of them, can you believe it? Well, sure, there are some meanies, but no one cruel that would harm a little girl like me ... or even someone smaller. So, because of that, there's nothing stopping sex between people of any age at all. Couple that with the fact that sexual urges can start at literally any age, and that all of us have an instinctive idea of the very basics of sex even from birth, that means ... a lot of sex with little girls!

Even better, our lack of taboo on sex with kids also translates into no taboos on romance. We also don't have any taboos against incest - we have very few at all, when it comes to sex... basically, just a 'no hurting, nothing unwanted' rule. So, it's not bad or wrong if someone falls in romantic love with a girl young enough to be their daughter ... even if that girl is their daughter. Romance leads to lifelong commitments like marriage, and more usually having babies! Where am I going with this? The short version is, it's totally fine for a parent to fall in love with, marry and even have children with their own daughter! And then they can do the same with that new daughter ... and so on, as far as they wish.

Now, I wasn't exactly in romantic love with anyone. It wasn't that I was too young or anything, it's just that I, well... was kind of more in love with sex. It's not like being someone's girlfriend in this world means you're exclusive or anyone, even if you marry them or have kids. We just don't work like that! Frankly, finding out about monogamy was mind-blowing. How do you people even live like that? It's crazy!

On that car ride home, my mind swirled with a new kind of sexual desire - part of me wanted mama to make me her girlfriend, and give me a baby. Of course, the problem with that was that I didn't have time to carry a baby. After all, my womb was constantly getting blasted during training, so it just wasn't a safe place! Not unless I could have a baby very fast. Hm, I sure wonder if that will come up later...?

The car pulled in the driveway, and Mama and I walked inside. Mummy was there at the door. Openly stroking her cock, she looked like she could barely wait until we came in. I found out that mama had told mummy about everything, including her plan to pound me into paste the moment we got inside, and both of my mums were extremely excited for the event.

As we walked in, mama picked me up, scooping me under her arm. My wet pussy pressed against the bare skin of her side as I latched my legs onto her and rubbed my face into the side of her breast.

"So, want me to record it?" Mummy looked really funny, all giggly and excited.

"Record it...? Oh! That sounds great! Oh, Gloria, you're so clever. Of course I want to record the first time my sweet little daughter takes the cock that made her." Mama reached over and hugged her tight, giving her a deep kiss. "C'mon, I'm so hard I can barely think."

They took me into their bedroom. The room had always been immaculately clean, smelling faintly of perfume or cleaning stuff - now the sheets were wet with pee and cum, small turds dotting the floor from where I'd loosed my bowels. The smell in here was that of heady, intoxicating sex - it was all my mums came in here to do, apart from sleep. I'd spent a few nights curled up in mummy's arms after she'd fucked me to sleep, with a gut full of both of my mum's piss, cum and shit, but this was the first time it was more than just idle sex toy usage. We were in here with clear intent, and my mama was finally going to get to use me too. I'd totally levelled up as a sex toy!

Doot-doo-doo-doo! Riley Evergreen, Sex Toy Level Two! You may now: get fucked by Mama's ridiculously thick cock!

Mama threw me onto the bed - literally threw me, crawling up onto the bed as I bounced. Mummy sat down on the edge of the wide bed with her phone, already recording us.

"Okay, Riley, you wanna tell the camera what's going to happen?" Mama was on hands and knees, poised over the top of me. With out difference in height, the tip of her dick was down by my legs - I reached my feet up to stroke at it, like I'd seen on shows and in class.

"Um, you're gonna fuck me?"

Both of my mums giggled. "Riley," Mummy sighed, smiling, "Look over here. Say your name, how old you are, and exactly what's going to happen to you. All the details!"

It took a few moments, but I was a super-genius, remember? So, I totally aced my first time being filmed like this. ... Okay, I guess I got filmed in the doctor's office like thirty minutes before this ... and I already messed up my intro ... whatever! I actually got to see the video again while I was putting this story about my life together. My mama came to use me, and she still had it on her phone, and... hey, don't get side-tracked! Here's what I said.

"Hi, mummy! Hehehe, or mama!"

"Or maybe someone else is watching?" Mummy prompted.

"Hi Andrea...? Or someone else!" Mummy made a gesture behind the camera and I copied her - both of my hands with two fingers making a V shape, a double peace sign. "My name is Riley Eber-- Evergreen! I'm five years old, and a couple months more than that, and today my mama's gonna have sex with me!"

Mummy gave me that look that said keep going, like when I got distracted telling a story. "Oh! Mama couldn't have sex with me 'cause her dick was too big for me! Now the doctor's fixed me up, and my pussy and butt and even my pee-hole and mouth can stretch waaay big to fit her! So, mama's gonna fuck me super hard today!"

"What do you think, Riley? This is the dick that made you - that put you in your mummy's womb." Mama grabbed her cock and waved it at me. I giggled.

"You alweady said that, mama. Are we gonna fuck now?"

"So much for a bit of drama! A'right, come here, my gorgeous little slut daughter."

Mama leaned back, kneeling upright. I went back with her as she pulled my hips, her hands big enough to nearly wrap around me. She slid me up, letting her cock glance off of my pussy and slide against my soft belly, all the way until my pussy made contact with the base of her dick. It always surprised me how stubby Mama's cock was - seven inches long, barely an inch longer than my five-year-old friend Belinda's dick. It was like all of the length she could have had went straight into making her dick thick. Sitting against my belly, it felt heavy. It was almost as wide as my thigh, twice the thickness of mummy's dick. And it was going to go inside me.

"What do you think, Gloria? Reckon it'll fit?"

"Of course it'll fit. You just got her a mod to make sure! Are you going to fuck her or what?"

Mama laughed. "Alright. Me in the future, or whoever's watching - maybe it's you, Riley? Hi, how are ya? Having a good day? Hope I'm giving you a good dicking while you watch this. Make sure you watch nice and closely, as I fill this five-year-old womb with the same seed that fathered her!"

In a flash, mama picked me up and positioned my pussy atop her cock. Her grip slid to my waist, properly holding me like an actual toy. At that moment, a change came over my mother - she stopped seeing me as a girl, as her daughter, and started seeing me as a very exciting new play-thing. A mere object to be fucked. I nearly came on the spot as I sensed that change came over her. I actually came as she slammed me down.

Seven inches long, wider than my fist, my mama's entire dick crashed into and past my cervix in the blink of an eye. I passed out momentarily, my eyes rolling into the back of my head as I went limp for a second. Mama took a moment to appreciate my pussy lips spread thin around her thick member, the huge bulge going several inches up from my crotch, the feeling of my pussy muscles attempting to tighten around her. Then, she began to fuck me.

When I say she fucked me, I do not mean we simply had sex. This was not your run-of-the-mill usage, no quickie with a sex toy to relieve yourself. Mama had a mighty need, had spent a month now desperate to be inside me - possibly longer, possibly much longer. Now she could finally have me all to myself, and she was not going to go easy on me. Her athletic body moved with full force, and in perfect synchronisation. She pulled out with her hips as she lifted me, and slammed her dick forward as she dropped me down, the base of her cock slamming against me like a jackhammer. All other sounds were drowned out, except for the SMACK SMACK SMACK SMACK of her skin smashing into my ass. Let me tell you, it was by far the best sex of my life up until that point. It was like a revelation.

I could barely see, my vision blurred by being rocked back and forth with no concern for my comfort. All the concentration I had was devoted to that thing slamming inside me with reckless abandon. When mummy shifted to slip her cock down my throat, I barely registered it - and only because mama slowed down slightly to help her line herself up. My blurred vision was replaced with the darkness of my eyes being covered by mummy's balls, and time itself slipped away as I was used, properly used for the first time in my life.

I couldn't recall how long it took before mama came the first time, but going by the video it was only about ten minutes. Of course, it didn't even slow her - I could only tell in the video by watching how my own belly grew a little bit in size as she flooded my little womb. Another fifteen minutes passed - Mummy had been satisfied enough to pull out of my mouth and return to watching on the sidelines, and mama came again. The whole video went for an hour, my mama never letting up for a moment. I was fairly certain I had been unconscious for the latter half of it all, my body completely limp. I spent the entire time in perpetual orgasm as my womb shaped itself to fit my mama's thick dick, and was left with a bloated belly and a momentarily gaping cunt for my troubles when she finally let me go.

At the end of the video, a part I didn't recall, mama slid out of me and flopped onto her back on the bed.

"Fuuuck. Sorry, Gloria, but I think that was the best fuck of my life."

"Heh. I'd be annoyed, but I've tried her pussy too. You'll have to try the rest of her next time - can't believe you spent yourself just pounding her womb for an hour!"

"I do love to get myself into a nice womb... if I weren't so pooped, I think I'd put it in you, maybe make Riley a little sister here and now."

"Fiona..." Mummy sighed. "Speaking of poop ... why don't we prepare some dinner for our brave little sex toy? Let's wake her up."

The recording ended there, but I definitely remember my dinner that night. Nothing but poop and pee for me! I didn't even need normal food any more, though it's nice to have a treat. If we ever get to meet, make sure to eat lots of chocolate and peanut butter before we have sex! That's my favourite way to have a 'normal food' treat these days.

The next time I went into one of my sex lessons, I was super eager to show off my new enhancements. The stretching machine now had my holes open the widest of everyone in the classroom, though they weren't quite as impressed when I mentioned I had got a modification. After all, it would be crazy if I'd managed to train myself enough for my holes to be opened wide enough for my fist to go inside without even touching the walls, all in the span of a week. I was even happy to demonstrate how much I could stretch my mouth and throat, by pushing my entire forearm down in there. It felt a bit weird, sucking on my own arm, but everyone gave me a little clap.

Of course, next week, everyone came back having had their modifications too. There were so many excuses, too! The three oldest girls had been meaning to do it for ages, naturally, and had gone and done it by themselves on the weekend. Angel-faced Yumi, who had also been acting as her classroom's toilet, went and got herself modified for the exact same reason I had. Her friend Charli, the blonde with the soft lips, had gone in with her.

Darla, the big-breasted, double-cocked eight year old, had gone in for a check-up on how she was growing and walked out with several mods - she could live off waste and cum like me, could lactate on demand, and had even made it so her nipples could be penetrated with a cock just like any other hole. That one she demonstrated by leaning forward and sticking both of her erect dicks all the way inside them, two bumps on top of her fat breasts showing where the heads of her cocks were. When she pulled them both out, they were covered in white milk - which her friends Yumi and Charli happily licked up.

Dana, however, had been so nervous about asking her parents that she had only been modified the night before. Her parents had convinced her to take on several mods as well, some of them based on easing the burden of her overactive balls. While it was possible to simply stop her body from producing so much, Dana didn't want that - our experience together in the bathtub had shown her that people liked that she could cum that much! I was so impressed with her ... and super turned on when she told me about the rest of her mods. First, she could live off waste and cum like the rest of us, and had her body made stretchier. She even had a special digestion mod that made her waste and cum become more high-quality the more times she consumed it. In addition, her cocks had been made more malleable - even when erect, they could still be bent comfortably and with ease.

"But why would you want them to be bendy?" I didn't get it... like I didn't get personal space, as I held a cock in each hand and played around at bending them.

"W-Well... it's so I can put them in me, if I need to. M-my stretchy holes means I can put my balls into my body if they're in the way, a-and my cocks too."

Dana demonstrated, with the whole class watching on. Even when she wasn't in hyperproduction mode, Dana's balls were still enormous. She grabbed one of them and pushed down on it. For a moment I didn't understand quite what she was doing, until the entire testicle dipped inside of her. Dana grunted, her body shuddering with a deep moan as it slipped inside her bladder, a spray of pee forcing its way up her cocks as it was displaced out of her. With some effort she managed to get the other one inside, her belly bulging out as she did so. Then, she bent her cocks down. With her balls out of the way, she was able to redirect her malleable dicks up into her own pussy. For a moment she looked like a totally normal, not even intersex girl, though with a weird set of three bulges where her pussy should be. Well, except for her belly sticking out. We learned almost immediately after that Dana hadn't actually practiced holding it more than once, and the pressure of everyone looking at her managed to arouse her. Her previously semi-hard dicks went completely hard, the parts inside her that were able to straighten out doing so by bulging her own belly. Three big bulges of cock were swiftly followed by the balls tucked into her bladder swelling in size. Dana fell to her knees, groaning as she accidentally fucked herself. Amy managed to free her dicks and balls from inside the girl's body before they got too big, and led her over to the bathtub to get her calmed down.

"Amazing, simply amazing!" Mika clapped her hands together, laughing. "To think you would all go and get your mods at the same time! You all have that competitive streak that makes for a wonderful sex toy!"

It was genuine praise, and we all glowed. Except for Dana, who was rather too busy pounding all of Amy's lower holes to listen. Despite the tiny girl's preoccupation, the lesson for that week started in earnest. We were going to have another stretching session, but Mika declared that the stretching machines weren't enough for us any more - that we would need to start working on more exciting things. That exciting thing turned out to be pregnancy and birth practice!

Now. As discussed earlier, I didn't exactly have time to get pregnant and deliver a baby - my womb was far too busy to play host. So, today, we were going to play pretend.

"These are your practice babies!"

Mika picked up a device that looked like a giant egg. Made of soft rubber, it was a bit bigger than both my fists together. It certainly didn't look like a baby, and was far too small besides. Well, until Mika pressed a little button on it. The rubber egg lit up and started to inflate, slowly growing to the size of a healthy baby. It wobbled in Mika's hand as it did so, like something was kicking inside it.

"For your first bit of practice, we're going to stuff this inside you in its full form and let it expand. You will keep it inside you for a bit while you perform other sexual exercises, to get used to the feeling of having a pregnant belly, and then you'll give birth to it!"

One of the eight-year-old girls, Yumi, raised her hand.

"Teacher, will we be simulating pregnancies in other holes?"

Mika smirked and nodded. This was a question I was very interested in, all of a sudden.

"Oh, absolutely. Regardless of whether you become a breeder or not, you'll almost certainly be expected to have something as large as a baby inside every one of your holes, and be able to remove that object."

Yumi nodded in thanks for the explanation, but I put my hand up straight after.

"You can make a baby in your bits that aren't your womb?!" I was open-mouthed with surprise. Mika gave me another nod.

"Sure can, with the right mods! Anyone here already modded for alternate pregnancies?"

Yumi raised her hand again, as did Darla.

"I'm able to raise a child in my bladder," Yumi gave that beautiful, angelic smile of hers. "I promised my little sister she would be the first to impregnate it, when I get the chance."

"Hehehe..." Darla gave a somewhat smug grin. "I'm ready to give birth ... from anywhere."

My eyes nearly popped out of their sockets. "Anywhere?!"

"Mhm!" She squeezed one of her huge breasts with one hand, and one of her balls with another. "My breasts can act as a womb, as can my bladder and both testicles. I can even be impregnated in my asshole and mouth."

I counted on my stubby little fingers. One, two, four, five ... "Eight?! Eight babies at once?!"

It wasn't fair! I just didn't have enough space in my body for eight babies, but all of a sudden I really wanted to be a mother to octuplets. But then I would have to get big boobies, and while I didn't hate breasts, I also really loved my lovely flat chest too. I would have to get a dick with balls too, which might be fine, but I told myself maybe later!

After our shock wore off, we began the practice. Each of us inserted the pretend babies into our wombs, all of us being forced to fist ourselves slightly to get it entirely in there. Not that it was even a bother - even with the unborn 'baby' being as thick as mama's cock, my new stretchiness made it no sweat at all to push it in through my cervix. Every one of us shoved it in with ease.

"Okay, everyone sorted now?" Mika grinned, on the verge of giggling at a joke she was about to tell. When we all nodded, she pressed a button on her laptop. "Congratulations, everyone! You're pregnant!"

The pretend babies inside us began to grow, and I watched in fascination as my belly expanded outwards. It turned out that, compared to the body of a five-year-old, a newborn baby was still quite large! Even filled up with cum and shit, my belly had never been quite this large, though it had got close. To top it all off, I could feel my 'baby' kicking inside me, the force of it nearly knocking me over as I tried to stand. Looking around, I saw all the other girls looking happily at their own and each other's big pregnant bellies - everyone looked so happy! I could tell everyone was really excited to try being a mother for real, too.

We hopped up onto our chairs at Mika's instruction, all of us ordered to fit both of the chair-dildos up our asses.

"I want all of you to bounce up and down, and get used to the new weight inside your body. These fakes are a bit lighter than a real child, but they'll give you a good idea of how your balance will change. Meanwhile, listen carefully to a quick rundown on some of the special laws surrounding breeding toys!"

It was really hard to get a good rhythm going on the dildos. They felt great, my asshole able to wrap around both of the thick rubber toys, especially when they rubbed against the bulge in my womb from inside. However, the kicking and wobbling from my 'baby', on top of the additional weight and size, made it hard to balance. I was used to moving while full of poop, so I wasn't entirely unused to this, but it was certainly new to have the contents of my womb moving on its own.

"Tell me, who has heard of the Soulless?"

Hoo boy. This one's a weird concept for your world! Cleo, her hard cock bouncing up and down as she did, raised her hand.

"Soulless are people or animals that are born without any thoughts, emotions or intelligence." Cleo was slowly jerking herself off as she explained, the slight pudge of her budding breasts bouncing as she moved. "They look just like regular people, but don't do anything on their own, so people say they don't have a soul. Just an empty body with no one home."

"Good girl!" Mika gave a thumbs up. "Does anyone know how Soulless happen?"

I had no idea at the time. This was the first time I was hearing about the Soulless at all, but I did vaguely remember seeing some sex toys who just didn't react to anything that happened. It was Yumi who raised her hand this time. Yumi, kneeling with her legs under her, rose and fell with an extremely precise, effortless rhythm despite her pregnant belly.

"It usually happens when a baby is made too fast. Not always, but when some people get special medicine to have a baby super fast."

"Absolutely right!" Mika gave another nod. "You can also get mods installed to ensure a baby you give birth to will be Soulless, and when a human produces a baby with an animal, the animal is almost always Soulless. Now, what's so special about Soulless people?"

A few girls put their hands up, and Mika chose Darla to answer.

"They're not really people! Not even not-people like sex toys aren't people! So you can do whatever you like to them!" Darla seemed quite excited about it, pre-cum dribbling out of her cocks as she fucked her asshole on the seat-dildos.

"That's right, girls! That's one of the special rules of breeding toys - it's perfectly fine to immediately have sex with a breeding toy's child if it's Soulless! You can even impregnate them, use them as toilets, anything you like!"

"Umm," Kim, the tall, bony older girl waved, "Isn't it true that you can have sex with a normal child too, even immediately after she's born?"

"Mhm, mhm." Mika nodded, now slowly jerking herself off to the thought. "Because we're all born knowing about sex and how to consent to it, even an unborn child can consent to sex! It's not uncommon for mothers to give birth to their daughters directly onto their other mother's cock, with the child having the option to move around the penis if she doesn't want it. Not that I've ever heard of such a situation! In fact, I was born directly onto my mother's dick - right into my asshole, came out the other end. I got kept as a cocksleeve for the first 48 hours of my life! It's my earliest memory, too."

Now I really wanted to have a baby. When I thought of who I'd like to have a baby with, who I'd like to see my newborn child slide onto the dick of, all I could think of was my sister and mothers. Especially Mama, with her fat cock - though a newborn would be more likely to go inside her dick than the other way around!

After finishing our impromptu lecture with some fairly boring legal stuff (the kind of stuff I didn't retain at all, to be honest), we went to play a game. The game was called 'Free Use Chasie', and was pretty simple. I mean, it was hardly a game at all - we could just all have sex with each other freely, like a big orgy. With some chasing to warm us up, of course. I was immediately scooped up and slipped onto an older girl's dick. Cleo held me by up under my armpits and pounded my ass freely, treating me like a proper sex toy. She even kept fucking me as she ran away from one of her friends, giggling as she was shoved down onto the bed. Fey had no intention of fucking her friend, however - with Cleo on her back and me seated on her cock, Fey slipped her dick down my throat and gave me a facefuck. Their pregnant bellies barely held them back as they fucked me freely.

We spent another hour like this, with me getting traded around eagerly. At one point, with my mouth freed of dick, I was able to wrap my lips around one of Darla's nipples and drink heady mouthfuls of her milk. Of course, she had me pinned on one of her cocks, the thick member squeezed into my bladder. My skin down below was wrapped tight around her member due to my pregnant womb, and you could see every detail of her dick as it slid in and out of my peehole. On the other side, one of the older girls was using Darla's other cock as an onahole - she was putting her own dick inside Darla's! It reminded me of when my sister and her friend had met inside me that one time, but these two were enjoying it. I would have to tell Andrea all about it. Another one of the older girls was having sex with Darla's other nipple, and I realised that part of the yummy taste of Darla's milk was definitely someone's cum from earlier.

Even Dana ended up enjoying the pregnancy practice. I got to watch as the limp, unconscious form of a recovering Dana was laid sideways on one of the desks, with Amy shoving the pretend baby into her womb. She laid there, completely unconscious with an enormous belly, until one of the other girls picked her up, flipped her upside down, and began eagerly fucking her mouth.

Eventually Mika stopped us, calling us back. We all were covered in each other's cum and fluids, my asshole and urethra dripping with stuff.

"Time to give birth! Now, with your bodies as stretchy as they are, this should be super easy for you - but it will use some muscles you've probably not used very much before! I'll guide you through your first time, and then we can stuff the fakes back in and try again!"

All of us laid down on one of the beds with our legs spread, Amy and Mika encouraging us to push. It felt like I was trying to poop with my womb, squeezing my insides to force the 'baby' a bit further out of my body. It was really tricky to get it past my cervix, the shape of it eager to slide back in unless I kept clenching tight. Eventually I figured out how to do it - hold tight, squeeze tighter, so as to not let it go back in any further. Once the egg-shaped 'baby' was at its widest part, stretching my pussy out as far as it went, Amy came by and pushed it all the way back in.

I squealed in surprise, orgasming. Giving birth already felt crazy good, my womb, cervix, and pussy all stretched out so wide and clamped down so tight, but having the whole thing forced all the way back up in a heartbeat was mindblowing. I would have peed everywhere, had my pee not already been forced out of me by being penetrated earlier. Catching my breath, I started again. My head was covered in sweat, my hands were white-knuckled around a handful of sheets, and once again, just as I was about to finish giving birth, Amy pushed the entire thing all the way back inside.

The third time was easier, though the orgasm when it got shoved back in was no less earth-shattering. It had taken me nearly twenty minutes to give birth on my first try, then fifteen on my second, and ten on my third. By the fourth one, I got it down to five minutes - still not good enough for Amy, who shoved it right back inside me. I looked around at everyone else, struggling along like me, and I felt compelled to cheer them on.

"W-We can do it!" I panted. "Everyone give birth! Everyone make a baby!"

There were some laughs, some cheers, but everyone agreed. The room erupted into grunts of concentration as we all forced our fake babies out of us as hard as we could. On my fifth try, I gave birth within a minute. The rubber egg plopped onto the bed between my legs, and I looked up in time to see the egg falling out of everyone else too - even Dana, who had entirely painted her upper half white with her semen as she gave birth. This time, Amy didn't push them all back inside us.

"Well done, girls!" Mika gave another clap. "That does it for our first practice! Who's ready for the second half?"

We all shared a look. Second half?!

In a few moments, each of us had been partnered up - this time I was with Dana. We were back on the odd chairs we had used for bowel control practice, where we pooped directly into each other's assholes to practice control and timing. This time, only one of us was given a fake baby - we all pretty quickly got the idea of what we were going to do, even before Mika explained.

"Now that you are all able to give birth quickly, it's time to challenge each other! See how quickly you can birth the baby into each other's wombs! Team with the best time wins a special prize!"

Dana and I looked at each other. She looked a bit frightened. Probably because I had that grin I usually get when I'm about to get really competitive. I crammed that fake baby back into my cunt and gently lifted Dana's balls out of the way before pressing my pussy lips right up to hers. Smooth, slick lower lips kissed with a quiet smack as I brought our legs into a scissoring position.

"Ready, Dana?"

"R-Ready, Riley!"

I pushed as hard as I could. It only took me about fifty seconds to give birth this time, though part of that was resistance - I wasn't forcing it out into open air now, I was pushing straight into Dana's womb! I watched with fascination as we briefly shared the bulge, our pussy lips both held wide open around the same massive object, before my belly returned to its flat state and Dana's became pregnant again. It took Dana a fair bit longer to push it back into me, but it was okay. I cheered her on the whole way, even as her cocks sprayed their constant gouts of cum - even if she wasn't fully erect or in the midst of a hard orgasm, she was always cumming when pleasured.

Dana and I fell into a great rhythm. She wasn't quite as strong as me inside, but I learned to relax my insides to make it easier for her to give birth into me. In no time at all, we were able to swap the fake baby back and forth within a minute, though most of that time was Dana pushing.

"Woah, look at Riley!"

"Holy crap!"

The older girls were watching us, struggling to even reach our pace. I'd become so fast that almost the moment Dana had finished giving birth I was already pushing my 'baby' halfway out. Maybe this is what I'm for, little me thought, giving birth to lots and lots of babies! I'd love to do that!

In the hour we did this exercise for, just before going home time, Dana and I were a blur of high-speed birthing. Dana had managed to get her time down to thirty seconds, and I could give birth in five. In fact, I think that practice made my pussy all that much more stretchy. Which was a good thing, given my upcoming prize.

"I think we can all say Dana and Riley are the winners of this one, eh girls?"

There were some complaints, but mostly praise - even with our insane pace, the rest had managed to get below a minute on their birthing speed, which was pretty incredible given it was our first times!

"So, what's my prize?" Handing Mika the fake baby, I stood there expectantly.

"Well, we're going to put your wombs to good use, of course! As toilets! Everyone - give Dana and Riley's wombs everything you've got!"

Without warning, Mika flipped me upside down, while Amy did the same for Dana. They slid their cocks down our throats to steady us, and I greatly enjoyed the feeling of Mika's massive foot-and-a-half schlong right inside my stomach. Mika pushed her hands into my pussy, hooked open my cervix and pulled me wide open. In no time at all, I felt several streams of pee pouring into my exposed womb, followed shortly by warm logs sliding inside me. When Mika finally let my pussy close up, she put me down. I looked down at my belly, now full of half of my classmates' waste - Dana had the other half, her tiny body made to look silly by her overdue pregnancy of a belly. I couldn't wait to eat it all when I got home, a whole evening of bending myself in half to slurp fat turds and juicy, shit-fermented pee out of my womb.

"Now, girls, I need to tell you about something very exciting. Next week, we will be beginning our first extra-curricular activity." Mika addressed us all as we grabbed our things to go home. "You will be staying here at the school from next Friday... right through to the following Friday! You are all going to experience your first experience being used for days at a time... and you are all going to be impregnated. Choose who you would like to impregnate you by Friday, or it shall be me or Amy who gives you your first baby!"

Dana and I looked at each other open-mouthed. We were going to be mothers?! I couldn't wait! But who was I going to pick?! How could I possibly pick between all of the women in my life, all of whom I loved with all my heart? If only I could figure out a way to give birth to all their babies...!

Chapter Text

"Riley, you said you'd only be a couple minutes."

"I'm nearly done!"

On that Saturday, I was sitting in my sister Andrea's lap. More accurately, I was riding her cocks - one in my asshole, one in my urethra. Wiggling my hips, I did my best to pleasure her despite my current distraction. You see, even though Andrea's friends were over, she was more than willing to let me use her computer briefly for important research. On the condition that she was present to make sure I didn't 'mess with stuff' or whatever. Like I was gonna! She probably didn't want me to see her search history, which was silly, because seeing the words 'is sex with two penises possible?' and 'is penis sex good?' and 'hot videos penis inside penis' when I clicked on the search bar was not a surprise. Andrea suddenly covering my eyes and deleting them was, though.

"What're you two doing over there?"

Miyuki and Shay were playing a game behind us, their furious controller-clacking coming to a momentary ceasefire. Mimi seemed more interested in why her host was still sitting in her chair than the fact that Shay was going ahead without her.

"I'm wooking up things about babies! Wanna see?"

"Why're you looking up stuff about babies? Gonna have one?" Shay snorted, joking around as she took a sip of her drink. She nearly choked when I said yes.

"Woah, what?" Mimi hopped up, peering over Andrea's big desk chair. "Li'l Riley's gonna be a mummy already?"

I forced Andrea to swivel a bit so Miyuki could see. On the screen was a page about how pregnancies worked, aimed at kids, with a few different tabs for related topics. 'FIVE TOP MODS FOR PREGNANCY FETISHISTS', 'All The Facts About Impregnation - MothersOfAllAges', even 'Pregnancy In Children - KidsExplain'. The last one was annoyingly bright and colourful, and felt a bit condescending, but the pictures on it were really handy. Andrea frantically reached over and minimised the window - probably to hide all of her silly bookmarks - revealing her blurry, poorly cropped background of a group of young women with very similar eye-covering haircuts to Andrea. Even though they looked really silly, some of them even wearing skirts and stuff, I bet they would totally make a great mess of me if I was their sex toy. Maybe that's why Andrea liked them?

"Aw, c'mon, Andrea, everyone knows about your porn site bookmarks!" Miyuki teased. "Oh, that urethra porn one wasn't there last time I peeked!"

"Sh-shut up, Mimi!" Andrea started to blush a bit. It felt weird to get all worked up over porn, considering how sex-oriented my life was. "I was just... curious, is all!"

"Can I see?" Shay poked her head over the other side of the chair, causing Andrea to flail in surprise. I decided to rescue her.

"Not yet! I gotta find the thingy!"

All eyes turned to me.

"The ... Thingy?" Andrea looked down at me, confused. I thought her face looked super cute from below, her fringe moved out of the way so I could see both of her eyes. I decided to tuck my legs under my body so I could bounce on her cocks better, enjoying the feeling of the doubled 8-inchers stroking the inside of my asshole and bladder.

"The thingy! The one that... the one that... mm! I can't tell you, Andwea! 'Cause it's a secret!"

"... You dork, how's it gonna be a secret if you're using my computer while I'm here?"

I thought that one over for a bit as I bounced. "Oh, yeah."

The girls had a bit of a laugh, and Miyuki leaned in and poked my belly - making Andrea squirm in surprise. She had poked Andrea's dick through my skin, after all. "What is it, then? The secret's out, Riley! Maybe we can help you find it?"

"I, um... I'm gonna get impwegnated. In my class, on Friday."

"Next Friday?!" Shay looked scandalised. "In class? ... Oh, right, the Program thing. But, like, you got a girlfriend or something, Riley? Damn, Andrea, your little sister's beating you."

Before Andrea could get annoyed at that, I shook my head. "No, no! It's for practice! 'Cause sex toys have gotta be ready for anything! Even having a baby, or lotsa babies."

"Right," Miyuki nodded - she was now slyly stroking Andrea's dick by rubbing my belly. "So, what is this thingy you're trying to find, then? You already seem to know you're going to have one, so what's the problem?"

"Weeell... they said I could pick. Who makes the baby with me." I looked down at my belly, where the bulge from Andrea's cock was. I would have stroked it to feel my womb, if there wasn't a hand and a dick in the way. "An' I can't pick. So, I wanna know if ... I can have babies with a bunch of people at once!"

"Woooahoho!" Shay laughed. "Riley, I bet you'd barely be able to move with a baby in you - more than one and you'd be stuck on your belly until they came out!"

"It's fine. I can move with my belly all big. I'm real strong, y'know?"

"I think I know something," Miyuki grinned, leaning in close to me. "Buuut, you gotta tell me! Who is it you want to have a baby with you? Your school friends, maybe?"

"Umm..." I stopped bouncing, squirming a bit in Andrea's lap. I didn't know why I was so embarrassed to say, but the crush I had was pretty obvious in hindsight. There's a bit of a blurry line between different kinds of love, at least in our world.

"Don't be shy!"

"Yeah, you can tell us, Riley!"

"Who're we gonna tell, dork? We don't go to your school."

The fact that they still thought it was some school friends made it a bit harder, but I knew I would have to overcome my shyness if I wanted Mimi to tell me her secrets.

"Well, I wanna make a baby with... with mama, and mummy... and Andrea."

Shay and Mimi gasped. I felt both of Andrea's dicks twitch as she suddenly tensed up. Then, both of the pair grabbed at Andrea and I, ruffling our hair, hugging us and squealing and making silly noises. I thought it was loads of fun, but my big sis just kept telling them to quit it. Once we were finally free, Andrea pulled me off her cocks and turned me around so I was just sitting on her legs. Without thinking, I reached down and took a cock in each hand, rubbing them.

"You want to make a baby with me, Riley? But ... I'm your sister."

"So? You're my favouwite sister."

"I'm your only sister, Riley."

I thought about that for a moment, distracted by a stray thought. "If I make a baby with mummy and mama, then... those babies will be your sisters! And my sisters?"

Andrea stared at me blankly. "Uh. I guess? Then... our baby would be sisters with them, but they'd be, like, her aunts? I think? Uhh... that's really weird."

"Oh, c'mon, it's not that weird." Shay gave Andrea a gentle punch on the shoulder. "My family's got tons of incest. My mums are both sisters, and also mother and daughter. My mum had me when she was ten, so she's not that much older than me."

It was our turn to stare at Shay.

"Wow, I didn't know..." Andrea looked a little shocked.

"Ohh! I could never figure out if that was your sister or your mum ... I can't believe she was both!" Miyuki looked less shocked, satisfied to answer a question.

"Umm... umm, Andrea!" I got her attention by rubbing both of her dicks really hard. "Andrea, what do you think? Will you give me a baby?"

"I..." Andrea looked down at me. "Wait, if we have a baby together, doesn't that make us girlfriends? I can't be girlfriends with my own sister, can I?"

Miyuki and Shay laughed. Andrea looked between both of them. "What, what? Am I seriously the only person who thought that was weird?"

"Yep!"

"Ahuh. I mean, my mums are married, so they're a bit more than girlfriends."

Andrea thought about that. I thought about that too - if Andrea was my girlfriend, then that meant we loved each other even more! And I do love Andrea. With all my heart.

"Andrea!" I reached up and hugged her tight. "I love you!"

My big sister softened a bit - normally she'd say something like Yeah yeah, Riley, Whatever, or Riley, get outta my room! or Riley, did you come in here just to pee on my bed? Weirdo! But this time, she hugged me back and said, "I love you too ... dork. I'll be your girlfriend, and I'll give you a baby."

My heart was pounding in my chest. Maybe if Andrea was my girlfriend, then my mums could be my girlfriend too?! But first, I had to know Miyuki's secret.

Mimi was more than happy to oblige, once all was said and done - even if we did have another embarrassing search history reveal when Mimi took over typing. Shay was blushing a lot more than usual, and her super-huge cock was hard. I would have to help her with that afterwards. Mimi navigated to a website with specialty body mods and medicines, and went to a particular product - the Multi-Partner Solution Solution.

This one is a actually a favourite in my current sex-toy toolkit. A special, temporary body modification medicine that you put directly into your womb, prior to having baby-making sex. A special nanotechnology formula excites your ovaries into producing multiple eggs, one for each droplet you put in. It also coats those eggs in a very special linked bio... something. I don't actually know how or why it works, I'm just reading off the label here! Basically it makes it so you can have a bunch of eggs in your womb, and only allow one person's sperm to impregnate one of the eggs. So, you could have babies that were fathered by a bunch of different people, all inside your womb at the same time!

My eyes went wide, and I gasped as Mimi explained what it did.

"We gotta buy it, super fast! A-Andreaaa! It says there's only one left! We gotta get it!" I swung around in her lap, squirming uncontrollably.

"Ugh, Riley, these sites always say that. To make you buy stuff without thinking." Andrea forced me to sit down, and both of her cocks slid into my asshole. Grabbing me by the hips, she started to use me to pleasure herself.

"It's cheaper than I thought." Miyuki looked closer. "It's only-- hey, what's that under discounts?"

The girls looked closer. To our great surprise, this was one of the products that you could get purchased for you free of charge if you were in a free-use sex toy program! We put in my student details into a very official-looking form, and ordered the solution. I was so excited that I didn't even notice Andrea cumming in my asshole - not that I was any stranger to being filled with cum without warning.

After that, we kind of forgot about the whole thing for a bit. Andrea wanted to show her friends some videos she found online about that band she liked, with a recording from one of their concerts. The music was really loud and a bit scary for my tastes, but I really liked the part where they pulled a girl up from the crowd and had sex with her while they performed. She was just a normal girl, not a sex toy, but I found it really exciting when normal people had sex too.

On Monday after school, the package arrived. It was a small bottle the size of a drink can with a special nozzle on the top that folded out. The bottle was all black, covered in colourful text that said about all the wonderful things it did, and had come with a hand-written note personally thanking me for 'volunteering to trial the new formula'. We didn't really know what that meant, but there was an email address to send back our review of it. Andrea wanted to throw it away, but Miyuki insisted we keep it.

The girls were over at the house again. This was mostly because their parents had come to hang out with mine, but Andrea had bundled me into her room to show the girls the package.

"So the instructions say..." Miyuki looked over a second piece of paper, with extremely dense writing on it, "You just ... stick it in and... spray it however many times for however many partners you have?"

"Did you ask your mums yet?" Shay leaned to the side a bit to get a good look at me - I was in her lap, hugging her cock in my arms as I nuzzled and rubbed it. Shay didn't seem to mind - We both knew she was going to relieve herself with my body later anyway.

"No, not yet..." I had been so excited, but every time I'd tried to talk to my mums about it they had either been busy with stuff or had stuffed me full of cock or waste before I could get a chance to talk.

"Riley!" I heard a shout from down the hall - Mama was calling. "Riley, come out here for a bit and say hello!"

"Well, go on," Andrea poked me in the side. "Why don't you ask them now? They'll be too busy doing boring grown up talking to use you, so you'll be able to tell 'em."

I nodded, wormed my way out of Shay's lap and ran down the hallway. In the lounge-room, I was surprised to see so many people. One of Miyuki's mums was here, and both of Shay's, including my own parents, all gathered up on the couches with the TV on quietly in the background.

"Oh, there she is! She really is precious!" Miyuki's mum gave me and my mums a huge smile.

I could tell pretty easily that she was Miyuki's mum, but I was shocked how close the family resemblance went. Short, curvy, with long, straight black hair and almond-shaped brown eyes, she had breasts each as big as my head and thighs soft enough for me to curl up and go to sleep on. She sat quite primly, with her back straight and hair neat, though her arms were covered in wonderfully colourful tattoos, and one of her nipples had an elegant gold ring pierced through it.

"No kidding, she's real cute!"

"But not as cute as me, right mum?"

Shay's mums were night-and-day different. First of all, one of them was clearly far younger than the other.

The younger one, the one who had given birth to Shay as far as I knew, was maybe about fifteen or twenty years younger than her mother/sister and wife. She had slightly curly brown hair that reached her mid-back, and a slight, slender frame hunched inwards in a way that made her seem meek or submissive. She was quite petite, though she still sported a ten inch dick - I couldn't help but notice she was rock hard, despite the lack of anything overtly sexy going on in the room.

The older of the two was older than my mums, and easily the oldest woman in the room - maybe in her late thirties or early fourties, she was also big in many, many senses of the word. Muscular, with short, messy brown hair that resembled Shay's, she had washboard abs and powerful arms and legs that rippled with muscle when she moved. Even better, her breasts were even heavier than Miyuki's mum's, though with one distinct difference - where her nipples should have been, she had two thick, erect 8-inch dicks. I'd never seen a lady with dick-nipples before, but even they paled in comparison to her primary member. Completely erect, the thing was about three feet long, maybe more, and as wide as mama's dick.

Shay's older mum (her grandmother, I guess?) eyed me with an almost scary hunger, like she was about to pick me up and eat me whole. I might have even enjoyed it if she did. Before I could contemplate what that would be like, mummy pulled me into her arms and hugged me tight. I hugged her back.

"These are Shay's mummies, and that's Miyuki's mummy. Say hello, Riley."

"Hello, Riley!" I waved at them. Everyone giggled. That joke always works.

"Oh, you cheeky li'l turd! You're lucky you're cute!" Mummy tickled me, dropping me into her lap in a giggling mess.

The adults all started to return to grown-up talk, stuff that my brain immediately tuned out. I sat there in mummy's lap, trying to find a good time to interrupt them and ask my question, when the attention drew back to me again.

"Riley, why don't you tell them about your time in the program?" Mama put a hand on my thigh and stroked it, feeling my skin.

"Miyuki keeps telling me all about how well you're doing!" Miyuki's mum smiled brightly. "Well, she says stuff like, that kid's crazy! She's made of rubber or something! and then wandering off to masturbate, but, I'd love to hear it in your words."

It made me giggle a bit to know that Mimi told her mum about what an amazing sex toy I was, but I told her. In the great, babbling detail that only a five year old girl can muster, I told them the sweeping epic tale of my increasing perversions.

"Then, just last Friday, after we pwacticed giving birth to a pretend baby, then Mika said we were gonna spend the whoooole week at school, an' also that we were gonna make a real baby!"

"Woah, you didn't tell us this!" Mummy looked down, surprised. "A whole week? Didn't you get a notice to bring home or something?"

"Hm, maybe they sent us an email?" Mama tilted her head. She grabbed her phone from nearby and started scrolling through it.

While I had been telling the story, Miyuki and Shay's mums hadn't been listening idly. Mimi's mum was still sitting straight-backed, prim and proper, except for three fingers knuckle-deep in her pussy that were making a quiet schlick schlick noise. Shay's mums were just openly having sex, though it was really a sight to behold - the older of the two's gargantuan cock stretched her daughter's womb out like a condom, the tip of it poking the woman in the cheek with every thrust. At the same time, the younger of the two was giving one of her mother's dick-nipples a blowjob. She did it slowly, like the act of doing so was comforting - I wondered if her milk tasted like cum, or if maybe her cum tasted like milk.

Then I finally remembered my question.

"Mummy! Mama!" I tumbled to the floor, rolling up onto my feet with a pose. "I gotta question to ask!"

"Hm? What's that, sweetie?"

"I want you both to make me pwegnant!"

My mums stared at me in surprise.

"That," mummy frowned, "is not a question. But, really? You want us to give you a baby?"

"Mmmhm!"

"Well, you can't pick both of us for your first time." Mama petted me on the head. "Who's it gonna be?"

I shook my head. "Wait here! Don't go aaanywhere!"

I left them both befuddled as I sprinted back toward's Andrea's room.

"Woah, sis! Slow down!" Andrea caught me as I nearly tripped over her. "How'd it go?"

"S'going good! Where's the ... the bottle thingy?"

Mimi pressed it into my hand, and I sprinted back to the lounge-room. It was an important item, and I'd seen in some of Andrea's games how to hold something important, so I stood with my legs apart, one hand on my hip, and the other hand holding the bottle high in the air. "Ta-da-da-da!"

Everyone gave a little clap, which was not what I wanted. "No, mummies, read it!"

Mama took it off of me and gave it a once over. She snorted in disbelief. "Where'd you get this? Here, Gloria."

She handed it to mummy, who had the same reaction. I explained how Andrea and I had ordered it, and by the end of the explanation mummy was shaking her head.

"I think we have to have a talk with Andrea about putting personal information into weird websites... oh well. This looks like the real deal, so...?"

"So, I suppose we can both impregnate our little girl at the same time!" Mama gave me a smile.

"And Andrea too!"

"Wow, Andrea too? Kid, your belly's gonna be stuffed so full you'll be stuck in place."

"How are we even going to fit in to do it all at the same time...?"

Questions and problems for later! I just couldn't wait for next Friday!

... and then it was next Friday. What? The rest of the middle part was just regular ol' sex and stuff. I had picked up a little side-project of talking loudly about cock-fucking in earshot of both Shay and Andrea, because it made them go all funny when I did it, but that hadn't quite got anywhere yet. We can talk about that later! Hey, remind me, won't you?

Us girls in the free-use sex toy program weren't going to attend classes at all on Friday. There was lots to set up, and Mika and Amy needed lots of time to make sure we had all been impregnated as soon as possible. Both my mums took the day off work, and Andrea got the day off school to come with me. I definitely had a spring in my step as I led them all in to the program room, eager and excited to show the women in my life that I loved the most the place that I loved almost as much as them.

The room was more lively than usual, with several more adults in attendance. Our desks had been pushed to one side, and several distinctly normal chairs had been arranged to face the front of the classroom.

"Woah, this room stinks." Andrea wrinkled her nose as she walked in. "Oh yeah. That's... that's a cum smell."

I nodded. "Yeah! That's probably 'cause Dana cums so much! I gotta in-to-doose you!"

"Introduce? Wah- Riley, don't pull me, I'm coming!"

I dragged Andrea by the hand towards Dana. Her normally shy expression had brightened considerably, her hand clasped in the hands of a girl a bit older than Andrea.

"Hi, Dana! This is my sister!" I tugged Andrea's hand, and she eventually got the idea that I wanted her to introduce herself.

"Yeah, hi. I'm Andrea. You're definitely Dana, alright. Hi," she waved at the older girl. "You look familiar."

The older girl was very similar in appearance to Dana - curly brown hair, dark skin, wide eyes with a soft, cute expression. She had one penis, a thin but foot-long snake standing to attention up between her moderate breasts. I guessed she was Dana's sister, but I was immediately proven wrong.

"Yeah, we go to the same school, I think. I think you're in the year below me? I'm Alba. Dana's my daughter."

Andrea looked a little surprised, and I was surprised too - Alba was maybe 15, and already had a 5 year old daughter, meaning she must have had her when she was 10. I suppose it wasn't too surprising, given that Shay's parents were the same way, but it was still unusual.

"Mum's gonna give me my first baby," Dana grinned. I could see now why she was so much more energetic than usual. "Is your sister gonna give you a baby, Riley?"

"Yeah, and my mums too!" I made a little pose. "Because I've got a special medicine, so I'm gonna have a bunch of babies."

Dana looked suitably impressed, but Andrea told me not to show off - when my mums caught up, having stopped to chat with some of the other adults in the room, we re-did introductions, and I got to watch both of my mums' faces when Alba told them who she was. Still, there wasn't much time to hang around - Mika was ready to get on with the show.

"Welcome, everyone, to the Free-Use Sex Toy program! Don't mind the smell or the stains - we get hard in here! Or maybe it's work hard?" The instructor gave a wide smile around at everyone and earned a few laughs. "All jokes aside, everyone in the class has really impressed me with their dedication - normally we have at least one drop-out by now, but I haven't heard a single complaint. Heck, I'm always double-checking the girls haven't snuck one of the stretching machines into their bags on the way out, they're so eager."

There was a bit of a murmur of approval between the adults in the room, though everyone seemed to be in more of a get to the good stuff mood. Mika cut to the important bit.

"Today, every program participant in this room is going to be impregnated. We're using a potent, child-safe pregnancy enhancer that will ensure that in exactly one week from now, each and every one of them will give birth. The effect is limited to this one pregnancy, but if you girls enjoy the experience then I will tell you that the school sponsors a variety of pregnancy-enhancing mods for aspiring breeding toys.

"In addition, each of the girls will be set up in a public space to be used as free-use sex toys. That will mean one entire week on display for anyone to use, though we ask friends and relatives to keep their visits brief and no more than twice a day. This is to simulate what life will be like when they are fully fledged toys. This is the make-or-break moment for most aspiring toys! You won't get to move from your place, sleep in your bed, or eat or drink anything but whatever cum and waste is deposited in you - I know that all of you have your waste consumption mods ready, so we won't have to break out the temporary treatments."

Mika looked at each of us girls, as though checking if any of us were going to back out now. She didn't need to say it - we all knew we could say no at this point, drop out of the program and try again another time. But none of us were going to. We all wanted to be impregnated, and we all wanted to be used. Mika gave a nod.

"Alright. We're going to move to the gymnasium to do our impregnations - the members of the basic program are going to come out to see us, and see what awaits them in the future, so make sure to put on a good show for them all! If you've got your partner, lead them there - if you want to request a student come down with us, come talk to me and I'll put out an announcement."

With that, Mika let us go. The gymnasium was a big building, set up mostly for sports and performances at the school, though today it had been covered in a massive array of padded mats. Covered in soft sheets and with pillows evenly spaced around, it was a giant bed for large amounts of baby-making. At the same time, I saw another group of about twenty or so girls walk in to the room, each eyeing us a bit nervously. They were girls of all ages, being shepherded in by a tall, curvy intersex woman who was directing them to sit in the raised stands to the side to watch. I gave them a wave, and a couple waved back, whispering between each other.

After a bit of set up, each of us students found a place to make their own, and stood or sat with their partner. I had a good look around at everyone. Dana was next to me of course, already sitting down with her mother. Andrea sat down near Alba and began to chat with her, while my mums sat down and whispered to each other. Looking at the rest, I got an idea of the kinds of people girls were eager to have their first child with.

Yumi, the angel-faced eight year old, was joined by another girl the same age as her. She looked a little embarrassed to be here, and I guessed she must have been a classmate that Yumi had roped into impregnating her. Her blonde-haired friend Charli was standing in front of a woman who was likely her mother, giving her a blowjob while she waited. Big-breasted Darla actually had a trio of younger sisters, identical triplets around my age that were playing around happily. Each of the three girls had sizeable, ten-inch dicks that flopped as they ran around.

The older, twelve year old girls were set up together, along with two adult women and a teenager. Cleo, the shorter, softer one of that trio, was sitting in the lap of a woman who was almost certainly her mother - nearly identical except for a 20 year age gap, Cleo was stroking the older woman's thick dick idly as she chattered with her friends. Fey, the one with budding breasts and a thicker cock, was squatting forward as her mother warmed up by gently fucking her ass. Lastly, Kim was enjoying a golden shower from a girl who didn't look related to her at all - I learned later that Kim was a slightly popular streamer, and had held a raffle for one of her fans to come and give her her first baby. The girl, a greasy nerdy lady with a seven inch dick and a mop of dirty brown hair, looked overjoyed as she recorded her urination on her phone. Given the way Kim was talking into the camera, I guessed she was streaming this too.

Mika gave a speech or something to the other sex toy class about what we were doing and how they would eventually be expected to take part if they wanted to become sex toys. Amy was doing much more important work - coming around with little capsules of the pregnancy enhancer.

"So, who's your partner, Riley?" Amy smiled at me as she fished out two capsules. She was quite impressed when I explained my plan, but I got the feeling she had heard of it before. As expected of an experienced sex toy! "Alright, better question - soulless kids, or real ones?"

This was actually a pretty serious question. Soulless kids could just be given away as onaholes or whatever, and I wouldn't have to actually take care of them or be their mummy. Real ones would mean I'd need to raise them and let them grow into full people. I'd have to not just give birth, but be a parent. With this deep, important question going through my mind, I totally ignored it and shouted, "Real ones!"

My mums tried to say something about responsibility or whatever, but they didn't seem to mind. Even though that meant that they would basically have to raise a bunch of granddaughters. I think we were all a little too horny to think about the consequences, but whatever! Amy handed me one of the capsules and I downed it, feeling a strange tingling deep in my womb shortly after.

"Don't forget this one," Andrea handed me the special bottle of solution solution. My mums helped me hold my pussy open as I sprayed it in there, pushing the nozzle into my womb to spray it. One, two ... did that spray go? I sprayed it one more time, just to make sure it was three. Close enough, I told myself.

"Alright, everyone! Time to make a baby! Have fun!"

Mika's booming voice was the starting gun to everyone's mad race to impregnate. In seconds, the entire room was full of the sounds of sweet sex.

Mama and Mummy laid under me, my legs folded back and right out so that they could slip in from either side. I felt Mama's dick slide in, stretching me wide, only for mummy's cock to pull me open that much more. Both of them in the same hole felt so fun, a new treat I'd never tried before as their cocks slid around each other at different paces. With me held up in mid-air facing up, Andrea was able to clamber on top and slide both of her dicks into my pussy as well. With all four penises inside me, my pussy lips were stretched thin, held open at irregular intervals. Their cocks moved at alternate paces, making for a really odd treat.

"This is some family bonding, huh?" Mama laughed, her hips pounding into one of my ass cheeks.

"Mm, maybe we should do this more often?"

"Ugh, a whole week without our toilet to fuck ... man, I'm gonna have to get up when I'm gaming."

My mums laughed at Andrea's complaint.

"My- mmh, don't- mmh! You- mmhgn... just- mm!"

"Take your time, Riley! Here, lemme help!" Mummy heard me struggling to speak and picked up the pace.

"Nngh! Nnngh!" I could barely talk at all as my body was ravaged. I wanted to say, 'why don't you just pee and poop on the floor, and I'll clean it all up when I get home', but Andrea probably knew that already. Right now all I could think of was how desperately my womb wanted to be filled with cum.

My cervix had turned into a hungry void, and there was a kind of burning tingling feeling around my womb. My ovaries were in overdrive, producing the most fertile eggs for the impregnating, and my mums' and sister's cocks were more than happy to oblige them. One by one, all three of them started to fill my womb to the brim with cum. After a solid minute of blasting my pussy full, the three were done.

I slipped back into mama's lap, laying flat against her belly panting for breath. There was a round bulge in my belly, for once not even from too much waste in my stomach. I put my hand there, and felt my womb speak back to me - all's good down here! You're pregnant, with so many babies! You're gonna be a mummy!

Once everyone else was done, my mums and sister said goodbye. They gave me a kiss, promised to come visit, and insisted they were eager to see their new children in a week's time.

"I hope I can fuck my daughters!" Andrea smiled. Our mums looked at her, a bit surprised. "What? I think I'm getting really used to kid pussy. I wanna try it!"

"Heh, maybe we should have sex with you while Riley's not home." Mama teased, ruffling Andrea's hair. My sister blushed, and didn't say anything. Was my family going to have fun with each other too? I was so excited to see what would happen in my absence.

With everyone cleared out except for the rest of the program's members and a few hangers-on, I could look around at my classmates and know in my heart that they were pregnant too. Everyone had a bit of cum running down their thighs, dripping out of their pussies, but there were a few surprises. Darla's nipples were both leaking what was clearly cum, and were larger than usual. All three of the older girls had cum dripping out of their urethras, and their cocks were slick and wet - I guessed that while they all had their wombs impregnated, they had impregnated each other's bladders. I was so excited to see more people were going to have more than one baby!

"Now, girls. Let's get you all tied up!"

I gulped, a little nervous as Amy came around with a trolley full of ropes, chains, ties and cuffs. Were we really going to be fucked for a whole week straight? ... I couldn't wait.

Chapter 8: Tied Up (Part 1)

Summary:

This time around, I, Riley Evergreen, superstar sex toy and professional five-year-old cumdump, am tied up in public to be fucked for a week straight! Perhaps we'll even hear from a few friends ... if you're lucky! Hey, fun fact: did you know that every orgasm you have while thinking about me or my story actually makes me more powerful? It's true! If you dedicate a million orgasms to me, I'll get to come visit your world! ... But you'll be a shriveled prune by then, so maybe refrain from doing that. Also it's probably not true. Much love!

Chapter Text

As it turned out, we were not all getting tied up together.

"Half the point of this exercise is how you deal with being away from your friends and family," Mika explained. "If you have your classmates nearby, you won't get the full experience. Of course, there will be plenty of times when you're paired up with another sex toy, and some of you may even be placed near other sex toys, but you will be experiencing your first time tied up alone!"

We were also not staying at the school, like I had originally thought. The lot of us were going to be placed around the town, for a variety of reasons that went over my head when I was little. But, I was surprised. Not only was I not going to be near anyone I know, but I was also going to be in a strange place, while having my first babies? Honestly, I was quite nervous then, but I remember being very, very excited - I've always loved making new friends, and I consider everyone who uses me a friend! Even if the only interaction I have with a person is to have their asshole pressed to my lips so that they can dump a kilo of shit into my stomach, that's still a kind of friendship to me!

Mika and Amy were only two people, so it was difficult for them to set up sex toys around the town all by themselves. If they had to do it by themselves, half of us would have been standing around until sunset - a tragic waste of time that could have been spent getting used. Instead, several volunteers came by to help. These women had some kind of relation to the places we were getting posted, though for most I only found out after the fact - owners of shops which we would be stationed outside, park managers, cleaners for public restroom areas, those kinds of things.

I was paired up with a tall, leggy lady with fair skin and wonderfully long, curly brown hair. She had a wonderful smile, and carried a little bag full of the stuff that was going to be used to set me up. I held her hand, and we stepped onto a bus to take us across the town.

"I was so surprised when they said I was picking up a little kid like you." The lady didn't have a dick for me to ride on, but she was more than happy to let me lean my head into her lap to lick at her clit.

"Mhm! I'm Riley, I'm gonna be the bestest sex toy ever." Slurp.

"Well, you're certainly eager, mm. You're not quite going to be just outside my store, but you'll be right nearby, so I'll be coming over to use you plenty."

The lady had a really nice smile, and her pussy tasted nice, so I didn't notice our trip go by until she pulled me up to her feet. When we stepped off the bus, I didn't recognise where we were at all. The lady might as well have taken me to another town entirely, and I wouldn't have been the wiser. After a brief walk, she took me to a fairly busy intersection. There were lots of shops and businesses, and tons of people walking around all over the place. The intersection wasn't for cars, so there was even space for things in the middle of the path. There were places to sit down and eat something from one of the cafes nearby, spots to relax under the shade of a tree, and a public restroom area right in the centre of it all.

I should probably explain public restrooms here! In your world, they're gross little buildings hidden away from sight, with lots of doors and partitions and stuff to hide people. In my world, they're almost always outdoors - toilets and urinals set up in the street for anyone to walk up and use, usually with a place for a free-use sex toy to be installed. When I saw it, I had the moment's thought that it was odd that there wasn't a sex toy set up in this one, until I realised, oh yeah, I'm the sex toy.

A trio of seated toilets on either side, with some troughs in-between for urinals, there was also a curious iron pole right in the middle. Well, curious for you. I already knew what it was. That's where you install a suspended sex toy!

"Alright, Riley," the nice lady smiled at me, "We're going to get you up there. Do you want me to hold onto your clothes?"

She pointed at my socks and shoes - I nodded. I knew that some people enjoyed the feeling of a little girl's soft feet, but I also had the afterthought of, I don't want my cute light-up sneakers to get messy. So, I slipped off my shoes and thigh-high socks, handed them to the lady, and wriggled my toes against the cool stone underfoot. The lady got me to lie down on my belly, and I realised as I did so that we had started to attract a few curious on-lookers. Everyone was fairly quick to put two-and-two together when she started pulling out straps and chains - there was an empty spot for a sex toy, and a cute young girl with cum still staining the inside of her thighs.

The lady pulled my arms up behind my back and bound them together with leather bracers, the inside padded and soft. They were like big bracelets that covered my entire fore-arms, stuck together so I couldn't move my arms at all. I could still move my hands around a little bit, but it felt unusual to be so completely helpless. She then folded my legs back at the knee and bound them together, so that the bottom of my feet were against their respective thigh. My legs could still be opened and closed freely, but I couldn't unfurl my legs. After that, the lady got out a special length of chain, with four ends. One end hooked into a hook in the bracers on my arms and two more hooked into the wraps holding my legs. The last one was way longer - it was for holding me up on the pole! She lifted me up and hooked the chain over a specially hooked section of the curved pole and dragged it further down to link up with itself.

I was suspended in mid-air at about waist height for most people, but the combination of the iron pole's horizontally curved section and the chain meant I could be raised, lowered and even angled differently. Even better, the chains didn't put any sort of stopper around my waist or belly - my babies wouldn't be restricted in their growth at all! Speaking of my babies, I felt a thick plug-shaped dildo slide into my pussy, along with some kind of sticky tape. I got to see it later - it had, in bold red writing, a message: "PREGNANCY IN PROGRESS - NOT OPEN FOR USE." After all, we didn't want someone accidentally hurting my babies before they were big enough to enjoy. I couldn't exactly rub my hand over my belly at the time, but I could definitely sense them - the special medicines I'd used left no doubt in my mind that I was rapidly growing a handful of new lives right inside me.

Once I was up on the pole, with my pussy sealed for the time being, the lady who stuck me up there tested everything worked. She lifted me right up, above her head height, and dropped me right down to the ground with the use of a special set of controls on the side of the pole. They were designed to be very easy to use - so that anyone, young or old could enjoy me. She tilted me this way and that, made sure all of my body was accessible from every angle, then set me back so my face was at crotch height. Without warning she stuffed her pussy into my face. I felt a warm splash on my chin and instinctively opened my mouth to drink as she peed, using my mouth as a toilet.

"You're all set up, Riley! Open for business! We'll keep that seal on you until your kids are big enough to avoid getting hurt by sharing the womb with people's cum and waste, so look forward to then!"

Finishing up her business, the lady gave me a pat on the head and walked away. Just like that, I was completely alone and unable to move at all. I didn't even see my first user - seconds after the lady who put me here left, someone came up behind me and stuffed a cock into my asshole.

"Fank- thank you for using me!" I shouted back, though she didn't respond. The lady was too busy, her hands tight around my hips as she fucked my ass with a good eight or ten inches of thick cock. Not long after, someone else came up and stuffed their dick into my mouth - a middle-aged woman who snapped a picture of me on her phone as she poured her golden liquid down my throat. The lady behind me finished up, another person joined in. The lady in my mouth finished, another person replaced her. I was suddenly mobbed, constantly under assault from people using me every different way.

A group of teenage girls saw me and made a comment about how small and cute I was - seconds later, all five of them were gathered around me, two of them peeing into my open mouth, one of them mounted up over me fucking my ass, and two more fucking my urethra together. They didn't say hello to me, talk to me, or even treat me like a human being. Right now I was a free-use sex toy, a public toilet where they could relieve their desire to cum and empty their bladders enjoyably. Once my mouth was free, I thanked them for using me.

"Oh! So cute!" One of the girls smiled as I said it and leaned down to take a picture with me. I was smiling super brightly in the photo. "Gonna have to tell Becca about this super cute toy, she'll love it."

I didn't get to watch them walk away - my vision was immediately filled with someone's ass-cheeks, and warm chocolate cake pressed my lips apart and slid down my throat.

The first few hours tied up there felt crazy. I had already thought my time in the program room, learning about all the different ways a sex toy would get used even in just a regular setting, was going to be outliers. Just weird stuff that might come up. I was not ready for some of those unusual things to be a constant of my life there. For starters, my mouth was primarily used as a toilet. The expectation was that my lips could make a seal over whatever urethra or anus was shoved up against it, to more cleanly slurp up everything they had to give. Then, my tongue functioned like toilet paper - I would give whoever used me a quick cleaning, or a thorough one if they stuck around for it, then thank them for using me. Simple as could be. My back end was where things were more exciting, and I couldn't even see it all.

Within the first few minutes, I had already had people cum and piss into both my bladder and asshole directly. It took about half an hour, but I felt the telltale sensation of someone using my asshole to poop into - a warm log pressing against my sphincter, prompting me to relax my muscles carefully and take the log into my own body. Not long after, someone wrenched open my urethra with her fingers before depositing their own warm chocolate into my bladder. My holes were getting stretched open wide regularly, especially when multiple people wanted to use my backside as a toilet. At one point, two kids a bit younger than me even stretched open my asshole as wide as it could go for fun. I felt one of them reach her hand deep inside me, to grab a piece of poop. I was sure I heard her mother tell her off for eating poop right out of a toilet - I hoped that kid would get to eat lots of yummy turds in the future!

By the time the sun set, I could feel my belly sagging below me. I was heavy with other people's waste, my stomach and bladder filled beyond what was possible for a regular human body to hold. I could feel other people's poop holding open my holes, and shuddered with the afterglow of near-constant orgasm. People had stopped using my rear end once it got over-full, and I spent hours unable to see anything except for brief glimpses between people fucking my mouth.

"Wow, doesn't anyone know how to flush? Geez."

I heard a familiar voice, though my sense of hearing was a bit overloading with the steady schlurp schlurp schlurp of a pair of dicks sliding in and out of my mouth.

"You're gonna flush it? Give me just a sec." The woman fucking my mouth picked up the pace and blew her load down my throat before sliding both dicks out.

"Thanks for using me!" I called out - I was almost surprised I managed to finish saying it this time, so I looked around to see why no one was taking her place in my throat. I managed to see one surly goth and her two friends - it was my big sister!

"You look like you've been very popular, Riley." Andrea, to my shock, didn't slide both of her dicks into my mouth. Instead, she went over to the controls on the pole and lowered me right to the ground.

"Mhm! I've helped lotsa people. Are you gonna use me too?"

"Maybe after, gotta flush you first. Lessee ... hey, wait, I'm gonna flush her!"

"Huh? Oh, sorry. Can ya hurry it up?" Some random stranger had been about to pick me up off the floor.

No wonder I was so over-stuffed - if flushing me meant people had to stop using me for a moment, then of course it would only work if I wasn't super busy. Andrea pressed a couple more buttons, and a mechanical whirring sound began behind me. I knew what was happening, had seen it happen to toilets before, but had never been on the receiving end. A set of mechanical arms with hoses on the end prodded their way into my anus and urethra, vacuuming up all the excess in the entrances - it felt like a set of tentacles were gently slurping up everything just inside me.

Flushing wasn't strictly necessary. All girls being used as toilets could easily process all the waste in their bodies for food. However, I hadn't quite been augmented for proper waste disposal - this quantity was far too much for me. The flush was there so that clogged-up holes could be used again - some people didn't enjoy only getting to fuck someone else's turds, though there were plenty of people who did. I personally loved the feeling of being covered in waste, but it was a sex toy's duty to serve people's needs - so, I pushed as hard as I could. It was always an uncanny feeling, 'peeing' out thick turds. The end of the log pressed into my bladder slid away easily under the pressure of all mushy slurry of waste and cum inside me, and in no time at all it was all rushing out of me - back to a nice, barely-bloated belly. Once the flushing was done, the mechanical arms retracted and Andrea raised me back up.

"There, much better. Honestly been waiting all day to cum inside you, Riley." Andrea wandered around behind me and squeezed at my butt-cheeks. "Our mums are gonna be around later to see you, too."

She slipped both of her cocks into my asshole, wasting no time in getting right up to speed. I felt another length slide inside my urethra - Shay had slipped her dick in underneath Andrea's legs, and was using the sheer size of her length to share my little holes. My sister and her friends weren't strangers to skinship - even casual acquaintances had sex with each other here in my world, and I'd definitely seen those three girls enjoying each other's bodies. Mimi used my mouth, emptying her bladder before shitting down my throat, then leaving me to eat her out while she waited for the other two to be done. They didn't take especially long - I got the feeling Andrea had been holding back, a heavy load pouring down my freshly emptied asshole. Shay let out a fairly prodigious load too, my bladder swiftly filling up again solely with her cum.

The trio didn't stick around for long. Andrea gave me a pat on the head, though swiftly regretted it - my hair was already soaked with cum and piss, and my sister wiped it off on my relatively dry belly. After another hour of being used by more random strangers, my mums showed up.

"Riley! How are you?"

"Mm? Mm!" A lady was currently fucking my asshole, her long shaft piercing straight through into my throat. With my mouth closed it was hard to see that she was doing so, but the thick lump in my throat rapidly rising and falling was a good hint. I opened my mouth to show mummy as she leaned in, which turned out to be the perfect time to spray her in the face with this stranger's cum.

"Ach, sorry!" The lady kept cumming, but I had closed my mouth, letting her seed balloon my cheeks.

"It's fine," Mummy laughed. "My bad, I didn't realise."

Mama laughed too. She leaned in and ran her tongue along mummy's cheek, slurping some of that seed off of her. There wasn't much left there, but mummy didn't bother cleaning it up - she had grown so used to her 'messy living' lifestyle that she didn't care about things like having a bit of cum on her. In fact, she was so unfazed by it all that she lifted up her dick and pressed it to my mouth.

"Mmph?"

"... Riley, open up, girl. What're you doing?" Mummy frowned at me, so I did as I was told. I had my mouth shut because the woman behind me was still cumming - the moment I opened my mouth, more spurts of hot cum splattered all over my mummy's cock and belly. Unperturbed, mummy slipped her cock into my mouth right alongside that gushing member.

"If you wanna just wait a moment, I'll stop orgasming in a minute or two," the lady insisted. "Mm, but having you in there too is pretty nice..."

"It's quite alright. This toilet-in-training is actually my daughter, so it's nice to see her getting used." Mum started to fuck my face, her cock sliding along the underside of the stranger's dick deep inside my throat.

"Really? Wow, I did think she was a bit young. So she's not a full sex toy yet. Wow! It's certainly a treat to fuck a kid this small. Wish they did home toilet placements."

Home toilet placement? I didn't know what she meant at the time. It wasn't entirely uncommon, but I'd never had one growing up - for a sizable fee, you could have a free-use sex toy installed in your home. Remind me to tell you a story or two I've heard about home toilets!

After the lady was done, mama came around and used my asshole too. My mums didn't stay long either, though mummy gave me a very nice kiss right on the lips before she went, a deep tongue-kiss that licked across all the cum and filth still inside.

"We'll come and check on you some time tomorrow, okay sweetie?" Mummy gave me a big smile as another woman came up to start pounding my asshole. I nodded.

"Are you gonna have sex with Andrea while I'm gone?" I asked.

Mummy put on a big show of thinking about it. "I suppose I would have to ask her, wouldn't I? She's not a sex toy, so it's up to her. If I'm really lonely, I'll drive down and fuck you silly, okay?"

"Okay. I love you, mummy an' mama."

My mums giggled and cooed, took a few pictures of me, and left. In no time at all, things returned to my new routine, a constant stream of people coming to have sex with me. However, as night fell and the shops nearby shut up for the night, less and less people came to use me. Those that did use me did so very quickly, or took their sweet time - people rushing home, or people taking advantage of a cute little set of holes without a queue or people waiting to use them.

At some point I fell asleep. I remembered a lady spraying a load of cum into my mouth, and closing my eyes as she pulled out, only to suddenly be woken to morning light and an insistent pussy being rubbed against my lips.

"Wake up, li'l toilet, I need to pee!" A teenage girl, maybe fifteen or sixteen, held the back of my head with one hand, and let loose her golden stream as soon as I locked my lips around her pee-hole. She had a small girl cradled in her other arm, maybe a year or so old, greedily drinking from one of her heavy breasts - it wasn't until I realised her other nipple was actually a six inch cock that I realised that year-old girl was giving her dick-nipple a blowjob. The teenager knelt down and shoved the other nipple into my mouth, letting me slurp away at it. When she came, her cum tasted like fresh, richly creamy milk. I drank every last drop eagerly, and the girl gave me a smile as she walked off.

The day went by fast. A rush of people in the morning used me, and my body swiftly bloated back out. I resolved to get myself a proper waste disposal mod, after a group of older women had to shoo off a few potential users just to get me flushed again. One fun thing I noticed though was that I was starting to get a taste for the things people had been eating and drinking earlier - fizzy energy drinks and bitter coffee made for sweet, dark pee, while a heavy, greasy Saturday breakfast made for some large dumps that retained some of that meat-and-eggs flavour. I played a little guessing game, trying to identify more flavours - the taste of fruits in a girl's load of cum, a thick, milk-flavoured log of poop from a jogger's protein milkshake, it all played along my tongue and gave me the most wonderful kind of breakfast.

In my womb, I could feel my daughters growing. It would still be a couple days before my pussy could be unsealed, but I could feel them growing bigger with every hour.

By the end of the day I was bloated out again. My stomach was so heavy with waste that it was nearly touching the floor, the skin showing the brown of my waste-filled bladder and stomach through the flesh. It was more than I'd ever held inside me, my own weight in cum, poop and pee stuffed into my holes like a soft bed for my unborn babies. Of course, my babies weren't the only ones enticed by my shit-filled condom of a body.

The first person to decide to use my overflowing backside was a jogger, shortly after sunset. She had a toned, sweaty body and a foot-long cock that bounced between her legs as she jogged down the road. I spotted her before she spotted me, and watched in delight as she immediately got hard. By the time she got over to me, her member was slapping up against her abs, and she gave an impressed whistle at the size of me.

"Whew, been a while since I saw a toilet overflowed like this!" It was starting to get to the quiet part of the evening, so no one else was using me. "Well, can't let this go to waste."

She went around behind me, and I felt her dick rubbing around my stretched open asshole. With one hand on one of my ass cheeks, she leaned into me. The strangest part was, I could barely feel her. The jogger was definitely thrusting inside me, pulling me up and down her cock, but I couldn't feel her shaft against the inside of my asshole. It took a full minute before I figured it out - she was having sex with the poop inside me!

"Do you like poop?" I asked, overjoyed.

"Huh? Oh, yeah, love it. Feel's great around my cock, especially when there's a belly full of it. You mind tightening up a bit?"

I did as I was told and clenched. Normally that would have shot a fat log of all those strangers' shit out of me, but with the jogger's crotch in the way it was all kept inside. She stayed with me for an hour, occasionally stopping to cum deep into the mass in my stomach, even as other people came up to use me as a cumdump or toilet. She only stopped when her phone began to buzz - strapped to her arm, she held a conversation with a friend on loudspeaker.

"Hey, where are you? I've been waiting for ages."

"Huh? I'm just using a sex toy down in the shopping district. There's a few little kid toys out, but this one's absolutely stuffed with shit, so I couldn't help myself."

"... you were meant to be here fourty-five minutes ago."

"Fourty-- crap! Damn it, I lost track of time. Hey, kid, do me a favour and poop into me - I wanna save some of this for later."

She pulled out of me. I couldn't see her, so I simply did as I was told and squeezed out as much as I could. With my asshole as stretched as it was, my logs were as thick as my thighs, a beautiful mix of lots of other people's re-digested turds mixed with their cum and pee. My jaw dropped when the jogger came around in front of me on her way past, and I saw that both of her balls were the size of basketballs with a deep brown tinge - she had made me poop down into her dick! The jogger sprinted off, completely unbothered by her new weight.

About an hour later, I noticed that I was starting to get a lot more users again. My asshole was cleaned out enough from the jogger that, despite my bloated belly, most people were more than happy to use that hole as well as my mouth. After a bit I figured out why people were here on a Saturday night - it was all people out to eat at the restaurants or go to the nearby movie theater, lots of happy families walking by. My personal favourite part of the families was when I was lowered down to be used by a kid closer to my age - my belly would squish onto the floor as I greedily ran my tongue inside a five-year-old girl's pussy.

Then, came my second poop-admirer.

"Mummy, look! Poop!"

A little girl a year younger than me ran over. She had an erect six-inch penis and short, messy blonde hair. Her blue eyes sparkled with delight, and I noticed that her soft belly was slightly round to match the chocolate smears at the corners of her lips. I also noticed that one of her fingers had a small silver ring. When her mother leaned down to scoop her up, I saw an identical ring on her. Despite the woman being somewhere in her thirties, and despite being the girl's mother, it seemed the two of them were married.

"Is my poop not good enough for you, honey?" The mother squeezed her daughter/wife into her heavy breasts, each as big as the girl's head.

"She's got lotsa poop. Can I play?"

"Oh, okay. But just for a bit!"

"I love you lots, mummy!"

After a deep, passionate kiss, the mother put down her little wife, and the girl ran around behind me. The woman lowered me right down onto the ground and slipped her thick ten-inch cock down my throat. "Remember, just for a bit - you can play until I'm done, alright?"

"Mm." The girl didn't seem to care - she was licking at the poop sticking out of my urethra, her little lips slurping and sucking at it. The girl was like a vacuum, sucking up piece after piece, her small hands tugging my urethra open wider and wider. She quickly reached my maximum wideness, and stuck both of her hands into my bladder. I thought at first that she was just going to pull more of the poop inside me out to eat it - instead she grabbed onto a handhold inside me and began to climb inside.

I'd never had another person inside me. I'd been stretched open and filled heavily, but the feeling of another human being entering me was amazing. My whole body shuddered in intense orgasm with every movement, even as the girl's hips slid inside me. She lifted one leg in, stretching me wider than I'd ever stretched before, and if it weren't for my mouth being full I would have screamed in pleasure as her soft little feet pressed against the fleshy edge of my urethra to propel her entire body into me. It was utterly uncanny, and it's a feeling I've still never quite gotten used to. The little girl had completely submerged herself into the waste-filled bath inside my bladder, and I could feel her slurping up her fill of shit stew as she masturbated vigorously.

"Hey, are you gonna use her urethra?"

The mother, still fucking my mouth, had slowed momentarily to talk to someone.

"Uh, yeah, I was gonna - is there a problem with it?"

"Just that my wife's in there. Don't want to shock you if she starts sucking you off, she's fairly fond of waste."

"... Huh. Never used a toilet with someone inside before. Thanks for the heads up!"

Two hands gripped my waist, and I felt my body raise up as the chains pulled me back to a regular height. Even as this other stranger slipped her cock inside my urethra, I could feel the full weight of another living body pressing down on my bladder. That body shifted and shimmied, and given the sounds the woman behind me was making, I guessed the girl in my bladder was ravenously slurping on her cock.

"Fuck, your wife is so good!"

"Isn't she? She's been sucking me off since the day she was born - we've been in love since day one! We actually got married on her first birthday - nothing says 'you may now fuck the bride' like spearing her all the way through in front of my whole family!"

"Daaamn... maybe I should get me a kid bride. You mind impregnating me?"

"Sure!"

The mother fucking my mouth pulled out, leaving my throat frustratingly empty. I heard her walk around me, and the tell-tale sounds of ass-slapping sex echoed out from behind me. It was easily the hottest sex I'd ever had in my life up until that point - a woman was fucking my waste-filled bladder while receiving a blowjob from a little girl who had crawled inside me and was even younger than I was, as her mother and wife pounded that woman from behind and impregnated her. I was just so happy to be a part of it all, that when the woman pulled out of me I called out to her.

"Thank you for using me, and I hope you get to have lotsa sex with your baby-wife!"

"Whew, best toilet stop ever..."

The woman left, satisfied in more ways than one, but the two wives were still there. I could feel the small girl inside me, licking the insides of my bladder clean.

"Okay honey, time to come out."

"Don't wanna! Can I stay?"

"What? No, you can't stay in there - she's not a bed. I'll let you sleep in my womb tonight if you come out right away, okay?"

The girl very quickly pushed both of her hands out of my bladder, and I cried out in surprise as I was wracked by another orgasm. The woman plucked her out, and I heard the slick sound of a cock sliding into a hole that wasn't mine. When the two came around the front - at the girl's insistence that she say thank you - I could see that the mother was gently fucking her daughter's pussy. A solid little lump went up and down on her round belly, and the girl peed on my face as her mother held her there.

"Tank you!" The girl waved with both hands at me, her body stained from head to toe with the slick former contents of my bladder. I could feel the hole gaping open heavily, and the roundness of the girl's belly insisted she had taken quite a bit of waste with her.

"Thank you for using me! Come again any time!" I smiled back. I would have waved, but, y'know, I was a bit tied up at the time.

That was two days down ... I still had five more to go!

Chapter Text

Day three of my being tied up was the day I made a friend.

... Well, okay, that's kind of a silly statement. Everyone who uses me is my friend, and it's not like we shared a deep heart-to-heart about our lives, but we were certainly together for a while. You'll see, when we get there!

Sunday morning went fairly uneventfully, though. I woke up to someone having sex with my throat as they had a chat with whoever was peeing into my asshole. I was quickly growing used to this feeling, of waking up to someone fucking me - the moment I realised what was going on, I got to work running my tongue along the shaft that was sliding in and out of my mouth. There wasn't much moving I could do, but I made a fine seal with my lips and bobbed my head where I could, all to make this stranger orgasm just a little faster. My reward was a warm cum breakfast, deposited onto my eager tongue.

A little later, my mums showed up. They checked on me, made sure to flush me, and both used me - Mama's thick cock in my asshole was just the wake-up I needed to start the day, and mummy's familiar cum taste really had me in a good mood.

"Thank you, mummy and mama, for using me!" I smiled brightly after mummy finished cumming down my throat. She began to pee on me, and continued peeing while we talked.

"Having fun, Riley?"

"Mhm!" I held my mouth open to drink up what I could, letting her warm, delicious gold fluid splash down my face and across my lips when I spoke. "It's lotsa fun being fucked all day!"

"And how are our babies doing, hm?" Mama put a hand on my belly - even after getting flushed out, there was a bump there. "A couple more days and we'll be able to unseal you, huh?"

"Then my babies can play too! Mummy, how's Andrea?" I looked up at my dear mum, the picture of innocence even as her piss splashed down my cute li'l face. "Did you fuck her yet?"

"Straight to the point, huh?" Mummy laughed, wiping the last few droplets of her pee off in my hair. "We... fooled around a bit."

"A bit?!" Mama chuckled as she slowly fucked my ass. "Gloria, we both sucked her cocks, then you bent her over the couch and pounded her for two hours while we watched a movie."

"Yes, but I think that's a bit tame compared to what Riley gets up to out here." Mummy ruffled my hair and leaned down to kiss me. "So, yes, I did fuck your sister. She quite liked it! I told her that her friends were more than welcome to join, but Andrea got a bit grumpy and told us not to tell them. She's so silly sometimes."

"I think Andrea wants to have pee-pee sex with Shay."

My mums looked at each other. "... Huh. I wonder who would be receiving...?"

"We have got to get those two together. Andrea with Shay, huh? What a cute couple they'd make!"

Both of my mums said goodbye to me, chattering about setting up Andrea as they wandered off. I was so glad to hear my family was getting along well while I was away, and that they weren't entirely missing having a living toilet and cumdump around. Even if I was tied up for the rest of my life, I got the feeling that they'd be okay... especially after I gave them my babies! They weren't even fully formed in my womb yet, and I could already tell they were going to be lewd girls like me.

As I was thinking about the contents of my womb, I saw a girl approaching me. She looked to be about 13, with small breasts and a tall, slightly curvy figure for a girl her age. She had a very long penis, as long as Shay's, and it waved back and forth precariously as she walked. Apart from her sneakers and socks, she was only wearing one more item of clothing - a red cloth belt, tied around her waist.

The cloth belt was a very distinctive one - bright red, with the text 'FREE' repeated over and over again in black. This was a sign where we lived that the wearer was happy to have sex with strangers. There were lots of different kinds of these belts, but it wasn't uncommon to see people wearing them from time to time. There was a yellow one to say the wearer didn't mind being a urinal, a brown one for someone with full toilet-related dietary preferences, a green one that meant they were happy to have sex with people who asked. The red one was slightly uncommon though - you didn't need to ask someone with a red belt whether they wanted to have sex or not, you could just use them. They were for people who wanted a similar lifestyle to a free-use sex toy, but without the commitment of having to be like that all the time. I hoped more and more people would wear them - after all, even if trading your life away to get to have constant sex wasn't for everyone, it was still an enjoyable experience to spend a Sunday getting plowed by strangers!

"Hi there!" The girl walked up to me and knelt down in front of me. Our faces were barely an inch apart, and her lips brushed mine as she talked.

"Um. Hi! Are you gonna use me?"

"Mhm!" She ducked forward ever so slightly, and gave me a quick kiss. "But, I thought I'd join you, too! You're a trainee, right? Is this your first time?"

I wiggled my head forward just enough to kiss her back. "Yes. It's so much fun!"

"Isn't it?! Well, when I heard there was such a small and cute girl just down the road from my house, I knew I had to come have some fun with you for the day! I'm Becky. Nice to meet you!"

"I'm Riley!" I smiled up at her as she stood up. "Are you gonna let people use you--"

Becky cut me off. The tip of her cock slipped inside my mouth, and it rapidly slid down my throat as she stepped forward. Her dick travelled down inside me, into my stomach, where she stopped momentarily to relieve her bladder. As much as I enjoy tasting pee, there's something satisfying about the feeling of your belly filling with warmth without ever touching your throat. After a minute of urinating, Becky moved forward again. Her dick pushed down into my intestines, my bowels wrapping around her cock as they squished and realigned to make that straight passage right back out the other end. My asshole slid open, and the head of Becky's dick pushed its way out with a couple inches to spare.

She wasn't done yet, however. I felt her weight press down on top of me as she crawled up onto my body - the clever design of my bindings preventing any discomfort at all. Becky threw her legs over the chains and bent her belly over the top of my head, resting her body against my back. Of course, she was a fair bit taller than me, but the contortion she had to do to fit around my head made us a much better match. Becky had draped herself over me, her heavy balls covering my face, leaving her own lower holes exposed above my head. I felt her lips press against my asshole, her tongue sliding inside to lick at her own shaft as she sucked herself off, her hips rocking gently against me as she fucked the inside of my entire body.

Becky was not joking when she said she was going to spend the day with me. The next time a person came up to use the sex toy, Becky was happy to let them have the pick of her holes or mine. It was an uncanny feeling, having the teen draped over me as she got fucked - I could feel whoever was inside her through the skin of her belly, or feel them grabbing at my hips as they fucked her mouth. I wasn't unhappy, even though it meant less people were having sex with me - after all, every time Becky got fucked it forced her cock to slide around inside me. The best part, however, was when people used her cock.

For the most part, this meant people penetrating her urethra - sliding their dicks into hers. It felt a bit like when the girl fucked my poop the day before, but a lot more tangible - the cock in my ass doubled in size where someone else was having sex with it, and every time anyone thrust inside Becky's cockhole the girl shivered and moaned in appreciation. When someone peed or ejaculated into her urethra I could feel that warmth travel down my body. There was even one person who used Becky's urethra to shit in, an unending log sliding directly out of her asshole and down her long cock, widening her tight hole and expanding her cock. I was even able to feel with my tongue as pieces of that delicious turd went down into the base of her dick, and dropped piece-by-piece into her balls.

There were also those who let Becky's cock slide into theirs as they fucked my asshole, and Becky always came buckets whenever that happened - it was so uncanny to feel someone having sex with me, only for the warm semen to be flowing back the other way. Of course, my urethra was still nice and popular - there were plenty of people coming over to use me just because of how small I was. By the time the sun set again, my bladder was filled right back up with cum and waste.

Every now and then, if no one had come by in a few minutes, Becky would start to fuck me as hard as she could. She was always constantly moving, her cock filling my throat and asshole simultaneously, but when she was under stimulated she would brace herself and start going as hard as she could. If there's any experience I can recommend you try, as soon as you can be a cute little girl with a rubbery body like mine, it's being absolutely pounded by a girl with a cock that's bigger than you. Every muscle inside me tensed around her shaft, milking out her orgasms, my own body shivering with pleasure the whole while - when she came, I could feel her balls tense, a wave of warm cum pulsing through her dick and through me to spray out all over the ground behind me.

When night fell and people stopped coming around, with all the shops closed on Sunday night, Becky still stayed with me. Even when there was only one or two people an hour, the girl was still happy to have sex with anyone who came by - and to fuck my body like an oversized onahole while she waited. I grew so used to having her inside me that I even managed to fall asleep, my eyes falling shut under the rhythmic pattern of her constant whole-body fucking. I had a wonderful dream that Becky had unchained me and had walked home with me still impaled on her dick, and that I lived as her cocksleeve for the rest of my days. Unfortunately, when I woke up, she was gone. I mean, it was a Monday - she probably had school and stuff!

Speaking of Monday, that day and Tuesday went by with very little excitement. Sure, I spent those entire days having my mouth, asshole and urethra fucked and filled with people's cum and waste, but there wasn't anything terribly amazing by sex toy standards. Apart from the occasional visit from my mums and Andrea, the only really interesting thing that happened was when a very serious-looking businesswoman decided to have a serious business conversation while using my asshole as a snack bowl. A whole business meeting, complete with all the dramatic and boring parts, while she routinely stuffed her arm into my anus and chewed on wads of strangers' piss-and-cum-soaked poop. If there was anything to be taken away from my first time being tied up, it was that a surprising amount of people actually enjoyed waste!

On Wednesday, it rained. It was really surprising - at first, I was shocked! I hadn't even thought about what would happen if I was caught out in the rain, but it wasn't a problem at all! In fact, it was the first proper cleaning I'd had since I got put up there. The only downside was that most people didn't want to brave the rain just to have sex with a cute little girl. Most, that is - during the busy morning and afternoon, when everyone was passing through the area, I was still constantly filled with someone's cock, hands or waste.

Thursday morning was the most exciting day, however. Clear skies, the morning sun pleasantly warm on my skin after yesterday's constant rain, I woke up not to the feeling of being fucked but to a sensation of movement inside me. Even ignoring the overnight accumulation of waste in my bowels and bladder, my babies had grown large enough to start moving around. It was the only time I struggled against my restraints - I was overwhelmed with the desire to pat my belly and say hello to my children.

"Good morning, babies!" I was absolutely beaming, grinning ear to ear. I could feel them, so ready to come out and join the world. I don't know how, but I swore I could sense them in there - they were happy too, happy to be alive, with their sisters ... and they were so horny. They weren't even fully grown, still absolutely minuscule babies not quite ready for the world, and I could tell they were already touching themselves in there. That's what they were doing, wiggling around - they weren't kicking, they were masturbating! Of course, it's not like I could see in there, but I was pretty sure my four babies were fondling each other. That's right - four of them! Even though I specifically took a medicine to give a baby to each of my mothers and my sister, I had one extra! I didn't know why, but I was overjoyed.

My babies being big enough to move and think and act also meant that it was now safe again to have sex with my pussy. A little bit after I woke up, the lady who put me on the pole came over to speak to me.

"I'm going to unseal your vagina now. Those kids of yours will have inherited your bio-mods - the new technology in them is pretty incredible - so it won't matter even if your womb gets flooded in the usual stuff." The lady explained all this as she had me lick her pussy and drink her morning pee. I'd grown to love the rich, heavy taste of people's first piss of the day, all their golden juice left overnight to get even tastier. Of course, once she was done and I had licked her clean, I was eager to ask questions.

"Will my babies get to drink lotsa pee?"

"Mhm!" The lady gave me a nod. "Well, if they want to. Given how your belly keeps wiggling about, I'd say your active little bubs are more than eager."

"And they can eat poop, too?"

Another nod. "They sure can. Even without teeth, you can still swallow poop. I suspect your girls might quite like it."

"And they can drink yummy cum, too!"

"Yes, yes, Riley!" The lady chuckled. "Eager little toy, aren't you? Going to have your babies working just as hard as you before they're even born! Let's get this thing opened up, then."

She moved around behind me and removed the sticker and plug. It felt really odd to have movement in my pussy again, even if the plug wasn't very big. I suddenly felt like my pussy was missing something - though I knew it would be for very long. The lady put a new sticker on me, right on one of my ass-cheeks - it said 'BABY ON BOARD - BE GENTLE!' with a cute little smiley face. Not that I knew at the time, but I hadn't even considered how rough things might get in there if someone didn't know. Not that my babies would ever be in trouble, one way or another. We're resilient people over here, even before we're born!

Not even five minutes after the lady left, my as-of-yet unused hole had its first customer. It was just a bit before the morning rush, with the early birds coming by to relieve themselves on their way to their jobs or schools. I was too busy getting my mouth fucked by two cocks at the same time to see who was the first one to poke her dick into my pussy, but I certainly felt it. I'd gone long enough without having my pussy fucked that I felt all tingly and sensitive all over again - as the stranger's cock slid down into my hole and poked at my cervix, I shivered and moaned, even through the double-penetration in my mouth stretching my throat wide.

My babies could sense it too. They wriggled happily in their warm womb when a spray of cum poured in through my cervix, and were just as happy when a wave of urine started to fill their cozy little home. Still, it was cum that really set them off. Whenever someone blew their load in there, they all kicked and wriggled in joy. I could even feel tiny tongues licking against the inside of my womb - my babies weren't even born yet and they already had a taste for semen.

By the middle of the day, my womb was full of people's cum and waste. I wasn't sure if it was just because I was off-limits for so long or if people truly preferred it, but nearly everyone who used me used my womb that day for everything they did back there. My babies were literally floating in people's waste, swimming in piss and cum and eating chunks of shit without a care in the world. I wondered what it might be like to be inside the womb like that, and hoped one day to find out.

"Riley! Is it open yet?"

Mummy came to see me, a little after what I guessed was lunch time. I was pretty busy at the time, but once she realised my womb was open she dutifully waited her turn in line. Once she got to my backside, she stuffed her cock straight into my pussy, the head of her dick passing through my cervix like it belonged there. Which it did! Something really strange happened though. I had a vague sense for where all my babies were inside me - they tended to float freely and aimlessly inside me, occasionally bumping the walls or swimming their way up a bit if there was something going on. But when mummy's dick pushed its way into my womb, I felt one of my babies swim eagerly up to the surface. It was the most directed I'd ever felt them, and mummy squeaked in surprise.

"Oh my gosh...! Riley, she's... our daughter's sucking my dick!"

It wasn't exactly something I could feel very well, but I could follow along with mummy's descriptions. My baby - our baby, definitely mummy's one - was leaning right up against the entrance to my womb, suckling on an adult's cock like it was her mother's teat.

"She's got about three or four inches in her. Wow... I've never had sex with an unborn child before, let alone my own. I mean, your mama carried Andrea, and she kept out of the way. I know you got excited when mama was fucking me, so maybe I should've seen this coming, hey?" Mummy giggled. I couldn't exactly talk to her - lunch rush, remember? My mouth was currently full of the second foot of an unbroken log of some lady's poop.

"Oh, Riley, our daughter's so eager. I can feel the inside of her mouth, her tiny tongue licking at my shaft, her little throat wrapped around the head of my dick. She wants my cum so bad, Riley!" Mummy grunted, and I felt her hips begin to move against my backside - tiny little thrusts, just enough to fuck our daughter's mouth. It barely took a minute for mummy to cum from the twin pleasure of my tight five-year-old pussy and the mouth of an not-even-born-yet cock sucking slut. I could feel mummy's dick twitching wildly as she came, giving our daughter her first take of the kind of mother's milk she would almost certainly be growing up on. After all, she had my stretchy mod and my digestion mod - this was a girl who could literally live on shit and cum from day one, and never eat a meal that hadn't come out of a human body in her whole life.

Mummy wasn't done yet. She was so rock hard from the feeling of a tiny mouth around her dick that she kept fucking me - but our baby was on the move.

"She's let go... is she all done drinking, you think?"

I didn't think so, but again, a mouth full of a stranger's cock - some young teenager probably skipping class, helpfully pushing all that shit from before down my throat - stopped me from answering.

"Huh? I can feel something... o-oh... Oh!"

Mummy and I came to the same conclusion at the same time. Our daughter hadn't left, and she definitely wasn't satisfied yet - instead, she had spun around, and pressed her backside against the other side of my cervix. She instinctively wiggled herself into the right position, and mummy gasped as her dick slipped into a tighter, smaller hole. My mummy had just slipped the tip of her dick into our unborn daughter's pussy.

"I'm... Riley, I'm having sex with our daughter! I'm inside her... if I thrust a bit more I can... unfh! I can feel her cervix!"

"Woah, are you really fucking her kid?" The teen pissing down my throat finally clued into what my mummy was rambling about.

"She's my kid too, and she's so horny! Mm, I think she was waiting for her mum, you know?"

"That's, like..." the teen thought about it for a bit, "So ... romantic, you know? Like, she wants to have your kid or something, even though she's not even born?"

My eyes widened at that thought. Could my own baby have a baby too?! Even if it was only a temporary effect, my womb had been modified to be ultra fertile and quick to gestate - that modification had to have passed on to my unborn children, even if only a little bit. I somehow knew in my heart that my daughters absolutely could get pregnant, and possibly even without such modifications.

I was brought out of my thoughts by the clap of my mummy's hips smacking into my ass-cheeks. A rapid plaplaplaplap of small, rapid-fire thrusts rang out behind me as mummy fucked our unborn daughter. I could almost sense our baby's lust, radiating out through me. All of her pleasure was being shared with me, and I was a shivering mess.

"Th-thank- guh- thank fors- th-thank- gnnhh!"

As the teen wiped her cock off on my face, I couldn't even finish mumbling out my usual thank you. My baby's pleasure was mine, which added onto the fact that I was still getting pounded by my own mother - I was experiencing two orgasms at once, and even my other babies were happily touching themselves to the feeling. Mummy was similarly incoherent.

"My baby's baby! Mmgh! She's so tight! Fffuck! I'm fucking her! I-I'm gonna fuck a baby into her! My o-own grand-daughter's gonna be a pregnant before she's even born! C-Cumming!"

Just like that, my baby was pregnant. My mummy, her grand-mummy, filled her tiny cunt full of warm cum. It was way too much for her tiny womb, the liquid overflowing into me. Down below her, in the huge, heavy bulge that was my waste-filled belly, her three sisters eagerly masturbated to the shared sensation of this impregnation.

My mummy eventually pulled out of me, panting heavily. As soon as her cock was out of my womb, our daughter sunk back down into the mess, back to sleep as she finished her rapid growth to full newborn baby size. The four of them inside me were already hugely bulging me out, even discounting that my ground-scraping belly was largely full of people's pee and cum - I was going to be huge by the time they were ready to come out of me. And they were coming out tomorrow. I was uncontrollably excited.

After mummy left, it was back to my regular day. I had partly expected Mama and Andrea to come by and see me, but I was on the other side of town from where we lived - that was a long way to come just to visit a sex toy! And they would see my babies tomorrow when we were all released. Thinking about all of us, at the time I wondered how my friends were going ...

Luckily, I was given the chance to hear from some of my friends from back then about what they remembered! They were all so excited to hear that I was telling you about our first times being tied up in public, and having our first kids.

First, I heard from Yumi. She's was the eight year old girl with the angelic face - a perfect cover for her truly devious love of having sex with everyone around her! She told me this:

The girl who impregnated me? Ah, that was just one of my classmates at the time. Honestly, I don't even remember what her name was, but I remember having fun with her. I'd spent the entire last week 'accidentally' touching her, feeling her up, unlocking the horny potential inside her. She can't have been the brightest bulb in the box - how many times can you fall for, 'Sorry, I accidentally licked your cock up and down as a joke'? When I told her I needed someone to knock me up for my lessons that Friday, she was so excited for it! She fucked me like her life depended on it, and she visited me every single day through the week to check on her baby - even though it was just going to be a soulless kid. I honestly think she just showed up to fuck me - maybe I did too good a job making her horny? Oh well!

I was placed in a public urinal stall by the park, so it wasn't too crazy-- oh, more detail? Okay. A public urinal stall is a special wall that's about half as tall as an adult, with individual compartments for holding a free-use sex toy. My arms were held tight against my body in the small gap in the wall, so that my face and chest were exposed on one side and my entire lower half was free on the other. There's a variety of tools on the back half for holding open holes so that you can freely pee into them, but you can also just have sex with the sex toy installed there. The spot I was in was fairly popular - it was on the main walking track to get from one side of the park to the other, so I was constantly being used by joggers, people out on leisurely walks, and especially kids. The stalls feature a fold-out step-ladder for using horizontally installed girls, so even the little ones could come up and pee into my open mouth.

Given that my baby was soulless, once she was grown enough for my womb to be unsealed, people had lots of fun trying to have sex with her inside me. I had to clamp down my cervix to stop her from accidentally getting taken away on people's dicks sometimes, given that she was so small that someone could just impale her on their length. I kinda regret only having one my first time - it looked like you had tons of fun giving birth to all four of them, Riley!

After Yumi, I heard back from Darla. Same age as Yumi, but with massive tits, remember? Huge breasts, two cocks - if I was anything less than perfectly happy with my beautiful little body, I might've been jealous! Here's what she had to say:

Wow, so, you probably saw, but those three kids that were with me were my little sisters! You're the same age as them, aren't you Riley? They've always been pretty horny little blighters ever since they were born - in fact, they started on the program the year after you started, right into the advanced course like you! Aaanyway, my sisters were the ones who knocked me up. I was going to ask my mum, but my sisters begged and begged, and then they argued over who was going to be the one to give me a baby ... well, until my mum said, "We can just get you a breast pregnancy mod, Darla!"

Total genius move. I mean, these big tits of mine were practically a sign that I was meant to be a breeder, so why not make them breedable? While we were there at the clinic, I got the rest of me done too. So, breasts, bladder, balls, even my stomach - that last one was new tech at the time. It still requires a pretty extensive overhaul of how your stomach works, but it makes a safe space for a baby to grow even if someone ejaculates down your throat or into your asshole. I mean, you probably saw when we all gave birth the next day, but I had loads of babies. I did make sure to give my sisters real kids though! They impregnated me every which way, leaving me with tons of soulless onaholes, but my breasts and womb got a real baby in them each for my sisters. Of course, the mods I got included a safe pregnancy add-on - all my holes were safe to use the entire time. I wouldn't make a very good sex toy if all of my holes were occupied just because I had a baby in them!

My installation? Yeah, I got put in the cafeteria of the local high school. Even though I had babies in there, my breasts were still producing plenty of milk - I got put in a combination dispenser and toilet set-up. People could come up and milk my breasts or dicks for something to go with their food, or just use me normally. I remember I was sooo surprised to find out that some teens love having sex even with my breasts and dickholes. I thought only the weird kids would want my cum-tainted breast milk or my semen that was mixed with other people's pee and poop, but it was more popular than expected! Not everyone was into it, but a lot more than I thought, for sure! I got way more popular once my kids were big enough to come out of their safety shells, especially my livelier ones in my womb and breasts - those girls were sucking and fucking from the moment they were even able to move!

The next person I got to talk to was Kim. At the time she was 12, the slightly skinny one of the three older girls, who had been streaming her impregnation.

I remember back then pretty well! Honestly, that was when my streaming popularity really exploded - who knew all you needed for streaming success was to let one of your fans impregnate you as part of an orgy with your schoolmates, all broadcast live for the world to see? Honestly I think that day was why I'm so popular now! You probably remember, but your fans- sorry, readers won't know - on that day I got impregnated twice. Cleo, Fey and I agreed that we should each have each other's kids, but Cleo and Fey wanted to give their first babies to their mothers. So we came up with a plan - we got a bladder pregnancy mod and had our babies there! All real babies too. Our little girls are doing great, I'll introduce you some time! When I asked my mum if she wanted to impregnate me too, she suggested I use it to hype up my stream - she's so clever!

During that week I had a stream marathon! I streamed the moment I got home, with me getting stretched on my toys while I did stream stuff, then left the stream running overnight. I got this crazy-cool automated fucking machine that could get bigger and faster if you set it, and someone helped me set it up so that when people put a tip on my stream they could make the thing fuck me in my sleep! So, a bunch of people bought raffle tickets, and this one girl won after buying like, five hundred tickets. So crazy! Her name was Melanie, and she came halfway across the state just to impregnate me! Of course, I gave her a real baby too - apparently they got married, like, a month after the kid was born. I still get lots of photos and Melanie's still a regular on my streams. Though, somehow, I never have a single photo from them where they're not having sex. Those two fuck like rabbits! They're, like, so compatible it's crazy - no wonder they got married so fast.

Ah, yeah, my installation. They had me on my back at one of the local playgrounds, strapped to a bench. I even got special permission for Melanie to help set up some of my streaming kit so that my entire week could be filmed - once again, my views skyrocketed from that. I mean, my viewers have some pretty particular tastes, and a livestream of me getting used as a toilet at a playground was gold for them. I don't need to spell it out, do I? Being at a playground meant that I was constantly being used by little kids and their parents. Almost all of the people who used me were younger than me, and the bench was low enough that even if some little toddler wanted to crawl up and use my open mouth as their toilet she could do just that.

Of course, I've gotta send you the clip from the stream of the highlight of the whole thing - this was on Thursday afternoon, right near the end. I hope your readers like it! ... Wait, they won't be able to watch it. Well, just tell them what happens, okay Riley?

Yes, unfortunately, I'm not capable of sending you the footage across the dimensional barrier. And hey, you'd probably get arrested in your crazy world if you had it! So, I'll describe it.

Kim was lying flat on her back on the park bench, her legs spread and fastened underneath along with her hands. Her belly was a pretty big lump, though her cock stood proud and tall against it. A little girl, maybe about three or four, was giving her clumsy kisses all over her face and licking away at some smeared poop while Kim giggled. Then, Kim's body suddenly went stiff and she gasped loudly - another girl was between her legs, shoving her arms inside. That girl was maybe five or six, blessed with a massive foot-long cock. She had a determined look on her face as she wrenched open Kim's pussy lips, and it became clear what she was up to the moment she shimmied forward and stuck her head inside. It took a couple of minutes of wiggling, but in no time at all the girl had crawled entirely inside Kim's womb.

Kim's belly bulged out even more than usual, and the tightness of her skin against this new intrusion meant that it was possible to see what was happening. The outline of a tiny baby pressed against the side of Kim's womb was suddenly joined by a pointy lump as the little girl slid Kim's unborn baby onto her long cock. On the side of the screen, the chat box is going wild - hundreds of people are typing all sorts of silly phrases and posting little excited faces, so fast that I can barely read any of them in time before they vanish. Everyone was going crazy! I was excited too, just watching it later - this six year old girl had been so excited to have sex with Kim's baby that she just couldn't wait. For the next five minutes, this little girl fucked the unborn baby at high speed, pressing her against the inside of the womb while she shook her hips.

A pulsing lump in the skin showed that the girl was cumming, her cock passing all the way through the tiny baby's body to blast the inside of Kim's womb. But, she wasn't done there - the girl curled up into a new position and grabbed the baby by the hips before using her like an onahole. She moved her little arms up and down as fast as she could, turning the inside of this unborn baby's shithole and mouth permanently into a massager for her cock. At the ten minute mark, the little girl's mother came looking for her, and was surprised to find her daughter inside a sex toy.

"Ginny! What've I told you about crawling inside girls? Finish up and come on out, or you're not sleeping in mummy's bed tonight!"

Well, finish up she did - by the time little Ginny was done, it was impossible to see what was going on inside Kim's body. She had cum so much that she ballooned out Kim's womb, giving her plenty of space to fuck her new toy. Fortunately for our little birthing fest on Friday, the girl's mother was able to convince her to leave Kim's daughter inside her womb, though Kim could do nothing to stop the small wave of cum that poured out when Ginny slid back out of her pussy.

Kim told me that one moment had made her one of the most popular streamers on the website she streamed on for a whole ten minutes, blasting past everything else that anyone else in the world was doing right then! I don't know much about streaming, but that sounds really impressive to me!

Now, unfortunately, I'm out of time. Buuut, next time, I'll tell you about a few more of my friends ... and what happened after we were let loose! Bye for now!

Chapter 10: Tied Up (Part 3)

Summary:

Okay, I swear, this is the last one! ... Well, for being tied up, that is. Stick with me to the end, and enjoy the birthing party! Lots of big, happy families today!

Notes:

Apologies for the delay! Other writing projects and life stuff keep me. I don't actually know if there's any way to be notified when someone posts stuff on Ao3, but, uh, if there is, do that! Then you'll know!

(See the end of the chapter for more notes.)

Chapter Text

I managed to hear from more of my old friends from the school program, and their time during that week we first got to try being tied up. For certain reasons that I'll get to eventually I wasn't able to hear from Dana, but I did manage to hear about her time tied up from her mother, Alba.

Did you know that there was a full-blown argument in the town hall about who was going to get Dana? Because her cum was so high-class, any business that had her even remotely nearby was going to get a bunch more visitors, so there was a bunch of debate over who should get the privilege. In the end, they came up with a slightly unique solution - Dana got installed in a movable cart and was transported around the town between different places during the week.

The cart was a really clever idea. Dana was laid on her belly on the top, arms and legs tied back to the sides of it. She had her head dangling back over one side, and her balls tucked neatly behind the cart. With her head back, her mouth was very accessible, and her balls hanging down underneath left her cute little ass and pussy open for playing with! The cart was modified so that her belly could grow down into the space underneath her. You could even reach down under there and grab one of her cocks to play with!

As predicted, Dana's cum was extremely popular. She started her first day inside a local cafe (and then out the front when they closed for the night), and the employees were constantly being asked to add her 'cream' to the drinks they were serving there. Because of how Dana's condition worked, the more she got stimulated the more she needed to cum - which was good, because she was providing litres of cum hourly just to keep up with demand! As word got out of this cute little sex toy with rich, creamy 'milk', there were lines going out the door for her.

The next place she ended up at kept her outside, just so the waves of people wouldn't clog up the store. And just because she was getting used as a dispenser didn't mean she wasn't getting used as a sex toy. A system ended up working out that followed her for the entire week, where two lines formed up around her - when the person who wanted some of her cum got to the end of the line, they could use her mouth or asshole while they waited. There were plenty of people who just wanted to fuck her cockholes too, and over the week her cum started to take on a different flavour.

Even though she was producing so much cum, there were hundreds of people pissing, shitting and cumming into her cockholes daily. All of it churned together, and her cum took on a really distinct taste. It had the deep, rich notes of different kinds of poop, with hints of chocolate and nut, as well as a tangy aftertaste from litres of other peoples' urine. The mix of other people's cum served to give her rich seed some really wonderful breadth to it - honestly, it was some of the best I'd tasted before, and I'm Dana's mother! I had basically been living off of her cum since she got big enough to need regular milking, and I was surprised by how much better it was when everyone pitched in. I mean, it's even better now that they've really perfected the formula - hey, why don't I send you and your family a couple buckets as my treat?

Charli was the last one I got in contact with. She was 8 at the time - the blonde-haired girl with the big, soft lips. Would you believe she ended up dropping out of the program? Well, not immediately - she found she rather enjoyed the freedom of the red sash after... well, you'll find out! Charli actually came and told me this one all in person, which made reliving some of the acts as she told them even more fun!

It was my mum who knocked me up. She actually had me pretty late - her parents were super conservative, so they wouldn't let her have a kid until she was 20. On her 20th birthday, she knocked up every single one of her friends, and ended the night with her womb so full of their cum that she couldn't move! Somehow she only ended up having one kid from that crazy orgy - me! It was pretty much a sign, I think, that I was gonna be way horny to make up for my mum's late blooming.

We actually got married when I was five. I know this isn't about the whole 'being tied up' thing, but bear with me! You see, when I was five I got really interested in my mum's cock - I loved playing with it, tasting it... well, one night, I wanted to try a thing I'd seen on TV, and I gave my mum a blowjob. Seeing how happy it made her, I totally fell in love. She asked me if I wanted to get married, and I said yes! It was so romantic - I had a lacy, see-through dress for our wedding ceremony, and mum pounded my ass right in front of all of her friends there at the party! I had no idea which one of them was my mum, but I certainly ended up getting used by my other mother that night, and filled fit to bursting.

I was in the basic program for a while - not everyone's as stretchy and crazy as you, Riley! - and was really proud when I got into the advanced program. Honestly I was only there to learn how to serve my mum better, and I learned so so much. But being tied up was really something else, and definitely showed me how much I loved my mum.

You see, it turned out that I wasn't as excited about having sex with a stranger as I was with someone who was related to me. Having sex with my mum was always the best, and I really liked getting used by my mum's friends - and their daughters, almost all of whom are my sisters! It took getting plowed for a week by countless strangers to realise that I was a total incest maniac! Still, it wasn't all bad. I got a really unique experience, because I was strapped up in the playground of a preschool!

My body wasn't just a toilet for all those little kids, or a cumdump for the parents and carers and other strangers wandering through the place - my holes were like a fantastic playground for all sorts of little girls! It didn't take long for them to realise they could stick their hands inside my urethra or my asshole, and that really fascinated the little ones. They could reach in and splash their hands around in my bladder, or pull out my poop to play with. Then one kid got the bright idea to stick both her legs into my asshole. She must have been two or three so she wasn't super big, but she really stretched me to my limit ... until the next time she did it, and her hips slid inside me too. And before you know it - slip! She fell into my asshole! None of the carers saw her slide inside me like that at the time, but when they couldn't find her there was a bit of a panic.

Some of the carers thought one of the strangers must have taken her - it's unlikely, but not unheard of, for a stranger to visit a preschool to find a lover she can take home with her for a time, and though there's meant to be forms to fill out to make sure kids aren't just lost it's also not unheard of for people to just run off like that. Still, the carers turned the place inside out looking for this girl - and then realised about an hour later why my stomach was giggling. A carer reached both of her arms all the way up my asshole and pulled her out, covered in my poop and everyone else's waste, giggling happily as they returned her to her waiting mother.

After giving birth myself, my baby actually lives pretty much entirely inside me, just like that girl! It was that moment that gave me the idea - my little girl only comes out to say hello sometimes, and spends the rest of her time in whichever of my holes she likes. She's inside my bladder right now - wanna crawl in and say hi? She's got a dick like her other mother, so she might have some fun with you!

Although that was all I managed to hear about the fun my classmates had during their week tied up, the fun isn't over yet! The very next day was when I sadly had to stop being a tied-up sex toy and toilet - back to being the regular kind of untied-up sex toy and toilet. However, it was also the day I was going to give birth! All of my babies were really excited, as though they could sense how eager I was to give birth. I was so excited to be a mummy, even if I was only still little myself!

I woke up to the sensation of sex. Not like usual - it was still so early in the morning that no one was coming by to use a public toilet. Instead, I woke up to the feeling of sex inside me - I knew straight away that my babies were having sex with each other! As they rolled and tussled and changed positions, I could tell that all four of them had penises, and that they had all just discovered how to properly fuck each other. I so wished I could have looked inside my belly to see what they were doing - I could only imagine the four of them gathered around, sliding their unborn shafts into each other's mouths, assholes, pussies and bladders. As they day went on, the four of them would not stop - though they did seem to find a position they liked. I even managed to work out what was going on - three of my daughters were ganging up on a fourth, desperately fucking her all over, slowly bloating her with cum. Not even born yet, and they were already having an incestuous gangbang orgy! Those girls of mine were really something else, truly horny little imps like me!

When the morning crowd started coming through, I got several happy remarks as anyone penetrating into my womb felt tiny hands, lips and tongues on their cocks. One jogger, a woman who had come by to use me at the same time every day, excitedly told me that she could feel three very eager tongues slurping against the head of her cock, trading places to suck her off. I figured the fourth mouth was a bit occupied, with one of her sisters' shafts. I quivered with orgasms just thinking about my precious babies. By the time it came to get me down, I was a shivering wreck, consumed by the need to see my daughters and pleasure them with my own mouth too! These four girls would grow up knowing their mother gave birth to them in an incestuous orgy, that their mother is a cum-slut public toilet, and that they were addicted to the very same incestuous, child-fucking gang-banging that brought them into this world! My family tree was already getting pretty weird - these girls were more than happy to make it a tangled knot.

Then, it finally happened. Mika, my free-use sex toy program instructor, walked up to me shortly after the morning rush with a stretcher bed on wheels.

"Sorry ladies," she waved to the handful of people waiting to use me, "I've got to take her back now. If you'll give me a moment to flush and remove her, I've got her replacement ready to go."

After the double-cocked lady slam-fucking my throat finished up, I was able to look over and see Mika readying my replacement. She was a fairly curvy woman about mummy's age, a proper and experienced sex toy! She gave me a smile and a wave as Mika bound her up. The flushing devices did their work, making my floor-scraping bloated belly return to a more manageable, if still enormous quadruple-pregnant roundness. With four babies in my womb, even with most of the waste flushed out of my holes, my belly was still as big as I was.

Mika lifted me off the chains, and my world span for a moment as she gently plopped me on my side on the stretcher. I was left bound for a moment, getting used to the strange feeling of being sideways instead of face-down and suspended, as Mika put my replacement into her place. Noticeably, a few of the waiting women decided to just use the regular toilets - I assumed they only wanted to use me because I was small, and I could hardly blame them! After all, being so small and cute is a privilege, and getting to have sex with a five year old girl freely is still a bit of a treat.

Once Mika was done, she freed my arms and legs, then helped me sit up. I thought I might fall over at first, but the sheer weight of my belly kept me leaning forward. The first thing I did once I was unbound was to run my hands across my belly - to feel my children inside my womb desperately fucking each other. I wondered why they were so insistent on having so much sex in the womb - after all, they were going to have plenty of time outside of me to have lots of sex, and I wasn't going to stop them from trying to crawl back in!

"How've you been, Riley? Damn, you're huge." Mika put a hand of her own on my belly as she carted me away.

"I had so much sex! And my babies are having lotsa sex too, Mika! They're having sex right now!"

I couldn't help but touch myself as I thought about them in there, my hands squeezing down under my hefty belly to furiously rub at my clit and churn the entrance to my sopping wet cunt.

"Who would've guessed it! Your kids, horny even before birth! Oh, Riley." My instructor gave a laugh. "Your mums are gonna really have their work cut out for them helping you raise them. And I suspect I'll be seeing them in my program in a few years, no less."

I nodded my head. I could just tell. All of my girls would be sex toys, one way or another. There was no way these little ones of mine were going to take up a chaste life, not after this amazing welcome to the world. And the best was yet to come! As Mika loaded me into a small van, she drove me back towards my school - to the birthing ceremony that was about to take place.

Mika had already carried a few more of my classmates back from their assignments, those girls waiting for me in the school gymnasium. I still needed help moving around - Amy brought out a special wheelchair to carry me over as Mika drove off to get the next person. The gymnasium was set up just like before, with all the beds across the floor. In the stands, waiting and watching, were the other free-use group - their eyes bulged and their jaws dropped as they saw me, with my wiggling belly as big as I was, carted over to a bed and gently placed down.

Looking around, I waved to my friends. I spotted Yumi first, separated by an empty bed between us. She had a nice round belly, her sweet angelic face plastered with cum and her straight black hair tangled and messy with people's waste. Unsurprisingly, she was vigorously masturbating with one hand, though her other hand was jerking off the still supremely embarrassed girl who had impregnated her a week ago. She had the exact same reaction to seeing my belly as the other sex toy class did, her cock squirting a spray of thick cum across Yumi's already painted-white flat chest.

Cleo, Fey and Kim, the trio of 12-year-old girls, were predictably together on a set of three adjacent beds as they gossiped and chattered about their week. All three of them were rapid-fire stroking their cocks as they talked, having to reach under their odd double-lump bellies to do so. Kim's strange friend, the greasy girl who won her stream raffle, was there filming them all as she too jerked herself off - she seemed to be enjoying the fact that the three girls were ignoring her, even as she sprayed ropes of cum over their pregnant bellies.

Charli was there already, in her mother's lap - despite her heavy baby belly, Charli was eagerly bouncing her 8-year-old ass on her mother's cock. Both of them looked super happy, and I swore I could see the outline of Charli's baby jerking herself off inside the girl's womb.

Dana arrived a bit after I did, in a similarly bloated state to me. But it wasn't her belly that was super bulged out - though she definitely had a sizeable baby lump, with at least one kid in her womb. Both of her testicles were massively inflated, filled to the brim with her yummy cum and more. Her balls were so big that when Amy carted her in, she had no choice but to sit the tiny cutie right down on them. Dana sat on her own testicles like a throne on the bed beside mine, though she didn't exactly look the part of a queen. Desperately rubbing two cocks with her hands while she suckled on the third, Dana looked ready to have her birthing done so she could cum up a storm.

Last to arrive of the students was Darla. Even I had to gasp in surprise as Darla was brought in. Darla had a pregnancy in every hole - her belly was heavy with a baby in her womb, bladder and stomach, both of her testicles hung low with the clear outline of newborn babies, and her usually large breasts were now hanging heavy and leaking milk as little lumps of moving baby pressed against the inside of her flesh. Incredibly, she walked in by herself, barely needing Amy to help walk her over to her bed. Both of her cocks were hard and ready to go, and I eagerly awaited watching her giving birth.

Not long after, everyone's family members started showing up. My mums ran over to me and cuddled me, kissing me deeply - I was almost surprised at the passion behind mummy and mama's deep tongue kisses, but even more shocked that Andrea gave me one too. There was a bit of roundness to her belly, which I later learned was because she had been letting our mums use her womb as a temporary toilet when out of the house - all of their morning pee was sloshing around inside her baby-maker, though my initial thought was that she was pregnant too. Both my mums distracted me away from that by rubbing my belly.

"Riley, you're so full up!"

"Our babies are in there, aren't they?"

"Are we really gonna ... have sex with them?" Andrea was shivering slightly, her dicks hard as she stared at my belly.

"If they wanna," I told her. "I think they wanna!"

"Mhm!" Mama put an arm around Andrea's waist, groping one of her ass-cheeks. "If you slip your dick into Riley's pussy while she's giving birth, if your daughter wants to have sex with you, she'll slide herself on!"

Andrea just stared at my belly, a twitch of pre-cum squirting out of the tips of her dicks and onto my face. I licked it up eagerly.

"Ladies and sex toys, may I have your attention!" Mika spoke into a microphone, cutting through all the chatter. "We are now ready to commence the birthing ceremony!"

A cheer went up among all the people watching and waiting, especially us girls who were ready to give birth.

"So that everyone can watch each other's first births, we're going to have you all perform one at a time, with our special cameras to catch all the highlights!" Mika pointed up behind us, to a giant set of TV screens positioned so everyone in the room could see them. I hadn't noticed before, but there was a little stage with some mechanical arm cameras surrounding a wide bed, just behind Mika. Amy hopped up onto the platform with a little box in her hand, and shook it up.

"It wouldn't be fair to us to pick who goes first, so we've got a raffle!" Amy waved at everyone. "Hello everyone watching at home! I hope you're ready to learn a lot, cum a lot, or perhaps both! The birthing ceremony will start with ..."

All of us girls looked at each other in open excitement as Amy ruffled around for a ticket. I didn't expect our live birthing shows to get broadcast out for people to watch, but it did make it a bit more exciting for me!

"... Charli!"

We all turned towards Charli, who was still bouncing on her mother's cock. The blonde-haired eight year old looked suddenly very sheepish.

"Um... I think she wants to, um, stay inside me. Maybe she'll come out to say hello?"

There was some chatter among the crowd, but Amy didn't seem too bothered. "That's perfectly fine! A lovely lesson there, folks - sometimes when a baby gets introduced the world in such a beautiful way, she doesn't want to leave her safe little womb! However, I think your mother has something that could tempt her to come out, just a little bit!"

With a grin on their faces, Charli and her mother stood up and made their way up onto the stage. Charli laid down on her back, and her mother leaned over her. If it weren't for the cameras, we wouldn't have been able to see a thing - but all the special angles made it super easy to see. The TV screen showed a close-up of Charli's slightly-gaping pussy, right as her mother slipped her cock inside. Surprisingly, the older woman didn't start fucking her daughter. Instead, she slipped her cock in as deeply as she could and wiggled it around like fishing bait.

"I feel a little mouth! There's my sweet girl!" Charli's mother cooed and encouraged her youngest daughter as she slowly slid her cock out of Charli's pussy - and bit by bit, the lump in the blond girl's belly shifted downwards. Suddenly, Charli's pussy lips began to part, and two tiny hands were revealed gripping onto her mother's dick. As Charli's mum pulled further back, a head began to crown - with half of her mother's cock down her throat. The tiny little girl slipped out halfway, leaning out of Charli's cunt to eagerly suck her own mother's dick.

"And there she is!" Amy pointed, bouncing on the spot. "Wow, she must be so comfy inside your womb, Charli! But not so comfy that she can resist her grandmother's cock, huh? Look at her go! A cocksucking professional from birth!"

Charli's mother simply held onto Charli's thighs as the tiny baby sticking out of her daughter's cunt sucked her dry. All the rest of us watched, masturbating eagerly, as the woman blew a load down the newborn's eager throat. No sooner was she done did the baby slip back inside with a quiet little squelch.

With her child refusing to come out fully, Charli's birthing was declared completed - her little girl was born, then unborn again! I held a hand on my belly, and wondered if one of my girls might choose to stay inside me.

Next up was Yumi. She dragged her 'partner' onto the stage with her, and took over the microphone from Amy.

"This onahole inside me is for my good friend here," Yumi put an arm around the girl whose name she couldn't recall, "Grown from her seed just for her! All you have to do is stick your dick in me and pull it right out!"

Yumi didn't lie down on the bed. She bent forward, pointing her ass in the air - slightly embarrassed to be seen on camera, the other girl quickly slipped around behind her and thrust her cock inside. In one clean motion, we all watched on camera as she pulled her dick out - along with a newborn onahole. A soulless baby, she barely struggled at all even as her first moments of life were as a cocksleeve for a girl who fathered her. The baby was small enough that Yumi's partner had thrust into the onahole's asshole and had the tip of her cock sticking out of the girl's mouth. The entire birthing process had barely taken thirty seconds, leaving Yumi's 'friend' standing there stunned at the new accessory on her dick.

"Go on, jerk yourself off! That's your new toy, now! Off you go!"

Yumi reached over and gripped the onahole by the waist, using the tiny newborn baby to jerk the other girl off. The girl shivered, nodded, and ran off stage to eagerly pump her new little toy - Yumi followed her, whispering encouraging words into her ear the whole while.

"Well, that has to be one of the fastest first births I've ever seen!" Amy gave a clap, and we all politely clapped along too - even though Yumi had already moved on, and had moved to the side of the stage to continue teasing her friend. Amy reached into her raffle box, gave it a shake, and picked a new person.

"Next up is... Kim! Come up, Kim!"

"Hey, I was wondering," Kim grinned, "Can Cleo, Fey and I all give birth at the same time? Because we each impregnated each other as well, so our kids can all be born together!"

Amy thought for a moment, and Mika laughed. The instructor gave a thumbs up, sending the three 12-year-olds into a giggling huddle impeded only by their bulging bellies. Kim gave a big grin and a few quick words to her camerawoman, and all three girls went up to the stage - along with Fey and Cleo's mothers, and Kim's lucky stream watcher Melanie. They each took up positions in a row beside each other before lying down on their backs and spreading their legs wide. The girls locked hands in the middle, and everyone else moved into position.

"We're gonna let our mums - and Kim's friend - have their babies first!" Cleo gave a thumbs up.

"Are you ready, mummy?" Fey grinned brightly.

"Everyone at home, cheer me on as I give birth!" Kim gave a double peace sign to her filming 'friend'.

Then, the three began to push. As you could probably already guess, the babies came out quickly, easily and painlessly - given the lust-filled moans from each of the girls as their pussies stretched open, I had to guess they orgasmed from the experience. I was already masturbating vigorously while awaiting my turn, but if I could have gone any harder at that thought I would have! The cameras caught every motion as the three girls expertly squeezed a baby out of their wombs - three darling little girls, into the waiting arms of their other mothers.

Cleo's mother, a short, curvy woman with a thick, average-length cock, held up her darling baby and looked her over with stars in her eyes. The little baby had a cock like both her mothers, already two inches long and hard. The woman, a lady in probably her mid-30s, lowered the happy, healthy baby down towards her dick. Like in your world, babies can't exactly talk, but we all instinctively understand sex - by lowering her baby down, Cleo's mum was asking the baby for permission to fuck her. Her baby said yes in the only way she could, by latching on with her mouth to suckle at the tip of the woman's dick. Cleo's mum held her darling daughter/grand-daughter there, allowing her to have her first meal of semen outside of the womb.

Fey's mother was much the opposite of Cleo's mum in many ways - tall, slender, with a foot-long skinny cock, she slipped her dick straight into Fey's pussy before the baby could come out. The other way for a baby to give consent was to either get on or avoid a dick in their way when they are being born - given that Fey's baby came out with her lips wrapped around their mother's long dick, it was safe to say she was eager to be fucked. Fey's mum didn't wait for the baby to be fully out before fucking her, her hips rocking back and forth through the insides of a baby so fresh she wasn't even out yet. When she finally came out, Fey's mum sat back and held her new baby upside-down by the hips, the tip of her cock poking out of the baby's tiny asshole as Fey's mum worked her up and down the shaft.

Kim's baby got an even more zealous welcome. Melanie had apparently set up the stream so that it was just using the official cameras for a bit, while she slipped her dick into Kim's pussy. However, she also stuck her hands inside, fisting Kim deep as she rearranged the baby that was already sliding out. With her baby coming out legs first, Melanie let the tiny baby slip pussy-first onto her cock, blessing her fresh womb with dick before she was even halfway out of Kim's body. When the girl finally slid all the way out, the greasy-haired woman held her baby under the arms, her cock bottomed out and bulging out the baby's round belly. The two locked eyes, and I could have sworn they had hearts in their eyes from first sight! Melanie doubled up and brought the girl's lips to hers, furiously making out with her new daughter and girlfriend as she pounded the kid's belly full of cum.

After a few moments, Amy got the two mothers and Melanie to clear off the stage for the final part of the trio's birthing. Cleo's mum cradled her new joy with a serene expression, even as her balls pumped a fat load down the tiny girl's throat. Fey's mum had settled into a more consistent, almost nonchalant mouth-fucking with one hand on her baby's waist. Melanie could barely be coaxed to move anywhere without being guided, as she was wholeheartedly fixated on making out with her soon-to-be-wife.

Fey, Cleo and Kim shuffled around a bit to face each other as they prepared to give birth to the girls who were waiting inside their bladders.

"So, who has whose baby?" Amy leaned in, curious to see.

"I've got Cleo's," Fey smiled, "And Cleo has Kim's."

"And I've got Fey's!" Kim smiled right back.

"Looks like everyone's having so much fun with their babies - do you think ours will want to have sex too?" Cleo asked her friends, an almost wide-eyed innocence in her excitement.

"Uh, duh!" The other two replied in unison. Kim added, "They're our kids. Of course they're going to be super horny!"

"Alright, let's count down!"

"One ... two ..."

The girls moved their hands down so they could catch the baby that belonged to them as soon as they came out of their friends' urethras. With a nod, they all said "Three!"

One interesting thing about bladder pregnancies that differs from womb pregnancies is that they're very quick. While the vagina has a bit of distance for a newborn to travel, there's not as much room in a bladder - the baby's head is often pressed right up against the other side of the urethra. As soon as the girls started pushing a squirt of pee splashed out between them, shortly followed by crowning heads. A slick coating of piss let each of the babies slide out with ease, right into the hands of the girl who fathered them.

As soon as the babies were out, each of the girls held their child up to their cocks. Even with both their vagina and urethra hanging wide open, all three of them was able to carefully hold their girls there to let them decide what they wanted to do. Predictably, the girls all leaned forward and locked lips with the heads of their other mothers' members. The three girls sighed happily in relief and pleasure as their respective babies calmly suckled, holding their new lives carefully in place.

"Isn't that beautiful, everyone? All these sweet little babies, getting along so well with their sex-toy mothers!" Amy gave an applause, and the crowd followed suit.

Of course, my clapping was more 'furiously masturbating and making the squelching and slapping of skin sound like applause', but that surely counts, right?

Once the girls were cleared off the stage, I noticed Kim scoop up the camera that was being used to film her, picking up her stream like it was nothing. The three older girls were in their own little world, enjoying their moment in the spotlight with family new and old. I couldn't wait for my turn!

However, I had to wait. Amy's next raffle ticket had Dana's name on it, and her mother Alba went up with her. Amy had to help Alba lift Dana up, her massive balls so heavy with cum that they greatly outweighed the little girl who they belonged to.

"Now, if you don't wanna get splashed, I'd suggest retreating back from the stage! Though, I don't think anyone here's going to get away without a bit of a coating!" Mika laughed, running a hand across one of Dana's massive balls. The girls from the other class looked slightly nervous, but also very excited - even though they were far away from the stage, who knew how hard Dana was going to cum when she gave birth?

Alba carefully pulled Dana's dicks out of her hands and mouth, bringing them down so that they faced forward towards the crowd like a triple-barreled cannon. Dana's dark chocolate nipples were rock hard on top of her heaving chest, the girl looking like she had been running a marathon - a pearl of white slid down from the corner of her mouth, and cum oozed from the ends of her cocks.

"Shall we get these emptied first?" Alba grinned. "Are you gonna keep them in, or ...?"

"I wanna ..." Dana panted, "Wanna fuck 'em. Wanna fuck their little assholes first, then we can put 'em back. Mummy, I wanna fuck them so bad!"

Dana's hands clutched at the base of her cocks, and Alba giggled. "We can arrange that. Okay everyone! Dana's gonna give birth to some cute little soulless toys first! They've been growing up nicely in her balls, and making her cum even tastier than usual! Open your mouths wide for this tasty stuff! It's normally pretty expensive, so this is a rare treat!"

Alba leaned in and over Dana, bringing herself into a slightly awkward position to rub all three of the little girl's massive cocks with her chest and arms. While there, she slipped her dick into Dana's mouth - the camera caught little Dana's head becoming a blur as she instinctively suckled on her mother's shaft. Poor Dana was on a hair-trigger, too - barely seconds after Alba started stimulating her, all three of her cannons were hosing down the audience.

Huge sprays of cum blasted out of her, a constant stream that pulsed in intensity as Dana's balls clenched. The hardest sprays splashed as far as the stands, and the girls of the other class either squealed in surprise or caught whatever they could with their hands and mouths. Closer to the stage, everyone else was simply plastered with sprays of cum - myself included, my flat chest catching a spray squarely that covered my round belly and face in one blast. Then, after about a minute of Dana's fire hose ejaculation, her sprays suddenly stopped. I cleaned the cum out of my eyes and watched closely on the big screens as three solid lumps worked their way up the foot of each of Dana's cocks. She was giving birth straight out of her balls!

Unlike a bladder pregnancy, which can come very quickly out of your lower urethra, a testicle pregnancy has to come out of your cock (unless you've been specifically modded otherwise!) so it can take a fair bit longer if you've got a big dick or three. As Dana's balls clenched in attempts to blast out heavy ropes of her premium cum, the lumps were pushed every so slightly up. There was still a bit of cum pouring out of the end of Dana's cock heads, the reason for which became obvious when the little soulless toys' heads popped out of Dana's cock holes. The cum was splashing out of their mouths, the sheer pressure pushing it through their assholes and back out the other end.

Alba carefully moved to slip each of the girls out of Dana's cock holes before they could be launched out. The first one she pulled out was accompanied by a huge spray of cum that splattered all over Alba's body, though the blast was muffled as Alba dropped the soulless toy's anus down - the girl who had just come up out of the dick now had that same dick sliding into her, and Alba slipped it right down to the base of Dana's cock before repeating the process with the other two. Once all three of Dana's new living onaholes were in their rightful place, Alba moved out of the way and began to reposition Dana.

Where Dana had been laying on her back against her own balls, Alba moved her so she was on her hands and knees atop them. Dana moved with a shivering urgency to grip the hips of one of her new toys, pumping her up and down her shaft for a few seconds before moving to another. Dana was so caught up in fucking her new toys that she didn't realise that she was already pushing out her other baby - her real baby, going right into Alba's hands. Alba didn't bring the child down to her dick like the others - instead she brought the healthy little tot around to Dana's front.

"Dana, look, it's our baby! You gave birth to her, my sweet girl!"

"Mmngh! I wanna fuck her too! Mummy, lemme fill her belly with my cum, and knock her uuup! FUCK!"

Dana swore loudly as her cocks blasted out another huge spray - her balls were starting to empty out, bringing her down closer to the floor even as the area in front of the stage was flooded with high-quality semen. Alba just smiled and brought the baby near the firing line of high pressure cum - and, understandably, the tiny baby reached up and locked lips with one of Dana's cocks.

The reaction was immediate. Dana reached up and grabbed her baby by the hips and mashed her down, bringing her lips in contact with the soulless toy already impaled there. We all watched and cheered as the tiny baby's belly filled and filled before splashing out the other end as litres of cum was sprayed through her. Dana was up there for several minutes before her balls were small enough to let her touch the floor. Alba set down the inflated cum-balloon that was her newest daughter before turning to help Dana one last time.

"Okay, before you go soft, lets get these girls put away." One by one, she grabbed the soulless toys off of Dana's cocks before stuffing them head-first back in the way they came. Dana shuddered and moaned, almost entirely insensate by now as her cockheads merely dribbled out their loads. Once they were all back in, Dana's balls looked heavy - and a bit lop-sided. Part of me hoped that she would get another baby in there to even things out!

Now, of course I was left for last in the birthing. Like as though I was meant to be the grand finale, after Dana's cum explosion. It was going to be a tough act to follow ... but I was more worried about being outshone by the only other girl left - Darla.

I was so impressed with Darla at the time, and I still am. She's one of the youngest girls I've ever seen have a pregnancy in every hole at once, and doing it as her first time giving birth? She was really brave! Her little sisters, triplets about five years with hard ten-inch dicks, waited eagerly on the sidelines. Once she got up on stage, Darla began almost straight away.

"I thought it'd be fun if I tried each kind of pregnancy, so here we go! I'm gonna get all my soulless toys out first, so if anyone in the audience wants an onahole, help yourself!" Darla gave a big smile and held her double cocks ready. A few girls from the other class came down from the audience, and even Mika came forth to get ready to claim one. Her first births were cock births, just like Dana's - except Darla's dicks weren't as big as Dana's. Both of her cocks expanded massively as huge lumps slid up her dual shafts, each revealing a sweet, tiny baby-shaped onahole. Mika took the first one and immediately impaled her without a second thought, stroking the newborn cocksleeve up and down her huge shaft. Another girl around Darla's age that I hadn't seen before tentatively took the other one and slowly began to fuck her as she walked back to her seat.

Darla then turned around and bent over, exposing her butt to the air. Her urethra slid open with a burst of piss, another soulless toy dropping into a stranger's waiting hands. Then her asshole followed suit - though the tiny girl's head came out first and seemingly got stuck. After a few moments, the onahole's mouth opened and a thick brown log began to fall out of her mouth - Darla was pooping through her baby sex toy! With part of her log still trapped inside, another girl took the treat-filled onahole and turned her upside down, thrusting her tongue into the baby cocksleeve's asshole to eat what was inside.

"Okay, time for my real babies! Ginny, you're up first!"

One of the triplets hopped up from her seat, rubbing her oversized dick as a head crowned out of Darla's exposed pussy. Ginny held her daughter as she emerged in a sweet hug that quickly turned into sex - the moment Ginny's daughter wrapped her legs around the five-year-old girl that fathered her, Ginny slipped her cock inside the baby's baby-maker and went to town. With her pussy cleared and all three of her lower holes hanging wide open, Darla turned around and parked herself on her butt.

"Minny, May, your turn! You remember which one's which?"

The other two triplets hopped up and stood either side of Darla, running their hands on the young girl's overly huge breasts. They each lined up the heads of their cocks and slipped straight inside, a picture-perfect nipple fuck like they had practiced. Both of Darla's fat tits began to wobble on their own as the little bundles of joy contained in each got herself ready to be penetrated. The two triplets eagerly fucked their big sister's nipples, fucking their own daughters at the same time - Darla bundled her arms up to squeeze her breasts, forcing the babies out. In a matter of moments, a splash of cum and milk heralded the birth of two new girls, eagerly bouncing on five-year-old cock. Minny and May went and joined Ginny, happily fucking their new daughters as Darla shakily stood up and took a bow. We all clapped loudly and cheered - Darla was incredible! Even with all of her holes gaping wide, she was still strong enough to stand up and walk off the stage, ushering her little sisters off so she could greet her new kids.

Which meant ... it was my turn. I gulped.

"Riley, up you come! Last but not least, our final set of births for the ceremony!" Amy waved me over, and with my mums' and Andrea's help I was able to get up on stage. I was laid down on my back, my legs spread wide for everyone to see while mummy held me up. Everyone staring up at me made me so excited, and I smiled back at everyone.

"Wanna say something, Riley?" Amy leaned in.

"Yeah!" I gave everyone a big wave, especially towards the cameras. "My name is Riley Evergreen! I'm five years old an' I've got a baby with both of my mummies and my big sister! An' I'm gonna be the bestest! Sex-toy! Ever!"

I'm not gonna lie, even little me had a flair for the dramatic - I had been quietly planning that with the scraps of brain-power I had left between orgasms. Speaking of orgasms, I started to push. All my practice giving birth made it super easy to let my first little girl slide out of my womb, her head coming out. My horny little weasel of a first child wasn't going to come out normally though - I could feel her tongue licking at the inside of my cunt, her hips bucking her hard cock against my inner walls as she was pushed out. She even moved her head to suck on my clit until my pushing brought her away from it. Her face was just like mama's - we knew immediately it was her baby, and Mama took her up.

"Oh, Riley! She's so precious! Heh, she looks a bit like Andrea, when she was born!" Mama held my darling little baby girl up in her arms, then lowered her down to her fat cock - that same cock that took me weeks of practice and a bio-mod to take comfortably. Of course, my girl opened her mouth and slid the head of mama's dick right in without trouble. And she slurped eagerly, so eagerly that Mama had to reposition her to let her take all of her thick dick right down her baby throat.

"How does she feel, mama?" I reached up and held Mama's hand.

"Amazing, sweetie! Oh, she's sucking so hard! Ffff...! She wants my cum so badly! I'm gonna fuck her... I'm gonna fuck my newborn daughter!"

Mama clasped both of her hands around my baby's waist, sinking one of her thumbs into the folds of her little pussy to rub at her miniscule clit. She lifted our baby up and slid her back down, slowly at first but then with such speed that, if I didn't know any better, I would have worried it might have hurt her. My mama was fucking my baby, my freshly-born slut of a daughter. Our daughter! The tiny thing wasn't so much as fussing, because she wanted her first experience out of the womb to be her face getting fucked by a cock as thick as her torso. Did I mention that part yet? Mama's cock is so thick, and my baby was so small, that her tiny little throat and neck was as wide as her shoulders. Mama wasn't long enough to fuck her all the way through, but she was wide enough to wear her like a thin condom.

I was so excited, shivering from post-birth orgasm and watching my mama face-fuck our baby so savagely, that I didn't notice that my second baby was already crowning. This next one looked just like mummy, so of course it was hers.

"Hehe, like mother, like daughter! She's the spitting image of you, Riley!"

Just like before, mummy's daughter licked and sucked all the way out of my warm cunt, even going as far as to wriggle around to run a tiny tongue against my asshole. If I hadn't been pumped earlier, I might have even had a treat for her to taste. Mummy held her up for me to see, and my baby reached out for me. I reached back and brought my lips to hers - through instinctive understanding, I pushed my tongue into her mouth and felt hers slip into mine as I made out with my second daughter. After a few moments mummy began to lift her off, a bridge of saliva joining us for a moment as we both panted.

"I love you," I smiled at my baby. Then, feeling silly, I looked over at my first daughter - still wrapped tight around mama's all-too-eager dick, and said the same thing.

"Woah, someone seems thirsty!"

I looked up, and saw mummy's daughter squirming in her hands to lock lips around mummy's dick - as soon as she obliged, the baby's lips slurped and sucked eagerly at the head of mummy's cock.

"Think she wants something to drink straight away - guess our daughter will get to have some pee!"

Mummy gave a soft sigh of relief as she emptied her bladder right into the stomach of her newborn daughter. From this angle I could watch as waves of piss were eagerly swallowed down her throat, and after she was done peeing mummy slowly lowered her down to get the tip of her dick right into our daughter's stomach. Not quite as rabidly eager as mama, mummy slowly fucked the tot's throat.

"I can see a little lump, Riley. Your daughter is already showing signs of pregnancy!" Mummy smiled at me, and I beamed back. "Guess the bio-mod passed down a bit, even if it was temporary. Probably won't take her more than a month or two to be a mummy ... wow, a baby with her own baby! Ugh, but that'll make me a great-grandmother! Then I'll sound super old!"

Mummy laughed, and so did Andrea and I. Mama was way too far gone, emptying her balls with a loud moan into our baby's stomach as she prepared for a second round. But, with mama and mummy's babies delivered, I only had two more - and they were probably both Andrea's. How could I know? Well, two cocks, two babies? It made sense to me at the time!

Andrea slipped her dicks into me, my pussy still hanging open from my last two births. "I wanna see if they'll slide onto my cocks! Mum already told me how she had sex with that one when she was in your womb, and I wanna try it too!"

Both of Andrea's dicks pushed into my womb, and my remaining two babies squirmed up to greet them. Andrea gasped.

"Th-they're sucking me! Both of them are sucking me off! W-wait, they're moving still?"

Sure enough, one of them was flipping herself around - my babies were so acrobatic, even by the standards of our world! Going by Andrea's descriptions, my baby slipped one of Andrea's dicks into her pussy, and after her sister moved out of the way she got the other cock-head into her tiny asshole. Andrea put her hands on my belly, feeling the vague outline of our baby through my flesh, and eagerly fucked her through me.

"Riley... Riley! My baby! Our baby!" Andrea's moans were loud, a more excited voice than the usually gloomy-faced goth gave. "Ffffuck, Riley! She's so tight!"

"Andrea, kiss me!" I held up my arms, and my sister didn't even protest - she simply leaned in and began to make out with me, even as her cocks pumped fresh cum into virgin, unborn holes. I know for a fact that Andrea impregnated her daughter then and there, with her arms wrapped around me and her tongue inside my mouth.

"O-okay... c'mon, Riley, give birth to her! I wanna see my baby already!"

Andrea shimmied back, and I squeezed - my baby went ass-first, her legs folded up as she traveled down my pussy and back onto Andrea's cocks. Even while I was trying to push her out, Andrea couldn't help herself - she eagerly double-penetrated her baby, even while the girl was being born. It made it take twice as long to get her out, as Andrea was inadvertently pushing her daughter back in as she pounded her. Still, after a couple minutes of pushing, my big sister had a little daughter eagerly cooing in her lap.

The girl looked a bit like Andrea, and a bit like me, though it was always a bit hard to tell with babies. Still, she had my sex-drive - she reached down to a pair of cocks as thick as her tiny baby arms and eagerly began to jerk them off. Andrea couldn't believe her eyes as her own daughter sprayed a tiny shot of cum onto her belly. I almost cried, watching how excited all of them were! My family had grown so big in the last several minutes ... but I still had one more to go!

However, when I pushed, my sweet little angel didn't want to come out.

"C'mon, baby!" I encouraged her. "Come out and greet your family!"

My mums and Andrea stopped their baby-fucking and looked. I could feel her inside me, curling up against herself - not in a birthing position at all! Maybe she was shy? Or maybe...

I thought back to earlier, to Charli's baby! She was so comfortable in Charli's womb that she didn't want to come out. I remembered even earlier how all of my babies seemed to be having an incest gangbang with just one of my girls! They were so eager to fuck her, like they wouldn't get to do it in a while... it all made sense!

"I'm all done giving birth!"

"But Riley--"

"My last baby is gonna stay riiiiight here! 'Cause she loves living in my womb, 'specially when it's fulla cum, and pee and poop! So there's one for mama, one for mummy, one for Andrea ... and one for me!"

I sat up and hugged my pregnant belly. I could feel and hear her inside me, wiggling around in a very specific way - I realised after a moment that she had to be sucking her own dick! I giggled happily, knowing my babies were all exactly where they needed to be.

My mums pulled their daughters off their cocks for a moment, two loud slurps followed by cranky baby noises. As soon as both girls had cocks put back inside them - mama's thick member utterly filling her baby's womb and mummy's long cock sliding up through her baby's asshole - they quieted down, content once more.

"What're we gonna name them all, Riley?"

I thought for a moment, really furrowed my brow and everything. I hadn't thought about it at all, but an idea sprung to mind.

"Why don't we all name our own?"

My mums looked at each other, and Andrea rolled her eyes. "You're way too clever, li'l sis. Well, you go first, genius!"

"Hmmm..." I ran my hands across my belly, thinking about my baby inside. "I think I'll give her a really, really good name, to say what she is! I'll name her ... Cumslut!"

Notes:

Hi all! Enjoying yourself? I love to hear from you on what you're enjoying, and don't forget to tell your (appropriately horny) friends! Have you had a good day? Did you remember to drink water, and have something to eat? Have you been taking care of yourself?

I'm thinking of writing some different stuff, unrelated to Riley's adventures. Probably with a different focus. I'd love to write something that's a bit more vore-centric, though I also have a fun fantasy setting with a living onahole girl that I'd love to commit to writing. Tell me what you think!

Chapter 11: Big Happy Family

Chapter Text

After the birthing ceremony, we went home.

It felt weird sitting in the car on the way back home, like it hadn't all quite sunk in yet that I was a mother now. Of course, being a mother didn't mean quite the same things for me as it does for people in your world, but it didn't make it any less exciting! Sitting in the back seat of the car, I was able to enjoy the sights and sounds of my mothers and sister enjoying their babies.

Inside me, Cumslut had fallen asleep. All the excitement of the birthing ceremony had worn her out, and now she was curled up tightly in my womb with her cock in her mouth. Next to me, Andrea was still slowly fucking her daughter, while my mums merely held their new daughters on their cocks. Mama was busy driving, of course, but her baby felt so comfortable being wrapped around a cock that was as wide as she was that she too had fallen asleep. Mummy's baby was cheerfully babbling, and going by mummy's excited shout and the sound of liquid trickling, I guessed the sweet little thing had started having her first piss - no doubt Mummy's own pee that the girl had drunk the moment she was born.

Once we were home, the eight of us sat in the lounge room together. Mama had walked into the room without even needing to hold up her baby, the girl so firmly snug on her erection that Mama could just wear her like an accessory. Mummy had pulled her little girl off her cock and spun her around to let her suckle at the tip of her cock.

"Alright," Mama smiled around at all of us, "How about we get these names out of the way?"

Mummy nodded. "Mhm! Did any of you have a clever idea already?"

Andrea was still sliding her daughter up and down her twin shafts, slightly distracted. Still, she looked up at the rest of us. "Um, can I name mine like how Riley named hers?"

Our mothers shared a grin.

"That's a fun idea," Mummy agreed, Mama nodding along with her. "How about we all give them nice, slutty names? These born-horny whores deserve fitting names."

"W-Well, um..." Andrea blushed, holding her daughter still. The baby wiggled her cute little hips, urging my big sister to keep fucking her. "I mean, I said that, but... It's a bit embarassing to say."

"That's understandable," Mummy grinned. "I remember it wasn't long ago that you were shocked at the sight of me bending Riley over the kitchen bench. Now you've got a newborn baby, and she's a born slut that needs her mother's twin dicks inside her. I think we're past the point of judging, sweetie."

Andrea gave a wobbly nod. She turned her head so her dark fringe could cover her face, and murmured out a name. "Th-think I'll call her Fuckhole. S'what I'm gonna use her for, anyway."

Mummy gave an encouraging nod. Mama flashed a thumbs up. Still, something worried me about all that. Wait, if my sister and mothers have greedy holes to have sex with ...

Mama's voice cut through my thoughts as she moved on.

"Fuckhole's a great name, sweetheart! Make sure you get used to calling her that, so she can get used to it too. I was honestly struggling to think of a good name on the drive home, so I'm glad you suggested we give them these kinds of names - 'cause this little one is clearly a Cocksleeve!"

Baby Cocksleeve stirred slightly as Mama twitched her thick cock, the outline of her shaft clearly visible through Cocksleeve's skin. Despite the massive penetration, the girl was still fast asleep. She really is a born-natural cocksleeve! I'm kinda jealous ...

"So we've got Cumslut in Riley's belly," Mummy pointed with her free hand, the other cradling her baby down by her dick, "Fuckhole for Andrea, and Cocksleeve for mama."

"Only one left to name, honey!" Mama gripped Cocksleeve by the waist and began rapidly pumping her up and down - the girl awoke, slightly disoriented, before falling back asleep even as she was jerked up and down on a cock the width of her torso.

"Let's go with Urinal."

Andrea raised an eyebrow. "Why Urinal?"

Mummy just laughed. "Honey, she's been sucking down my pee basically the entire time. I don't think she can get enough!"

Great, I thought, not only are they going to be fucking only their own daughters, they've even got a toilet! At this rate, I'll...

"Riley?" Mama waved a hand at me. "Earth to Riley? What's with the grumpy face, kiddo?"

"'M not gwumpy," I frowned, crossing my arms over my bloated belly.

Mama stopped pounding Cocksleeve, pushing her back down until her tiny ass reached the bottom of her wide shaft, before crawling over to me. Mama scooped me up into her arms and cradled me like a baby. "Someone's a bit jealous!"

Andrea snorted with laughter, and Mummy suppressed a giggle of her own as she said, "Stop teasing her!"

"'M not jeawous!" I grumbled back. I couldn't keep a straight face for long, though - Mama began tickling me rather viciously, sending me into a fit of giggles. Just as I was trying to catch my breath, she pulled my face right up to hers and began to make out with me. For a full minute straight, Mama's tongue explored the inside of my mouth as she furiously rubbed my clit. It wasn't enough to make me cum, but it was enough to make me calm down. As she broke away, a trail of saliva between our lips, Mama fixed me with a stern look.

"Is happy Riley back now, or are you going to tell me what's wrong?"

I squirmed for a bit - I could feel Cocksleeve under my butt, rubbing her head against me as Mama's cock twitched. "If evewyone's got babies to fuck an' use as toilets, then no one's gonna use me as a sex toy or toilet any more."

Mummy cooed and stroked my head. "Oh, that's not true, Riley! These little daughters of yours might be colossal sluts, but they're not going to replace you!"

"Yeah, kiddo." Mama put me down gently, and I wobbled under the unfamiliar weight of standing with a full baby belly. "After all, who's going to be their toilets? And we'll have to blow plenty of loads inside you to keep Cumslut happy and fed too."

I nodded, rubbing my belly, but I was still a bit upset. "But... you aren't gonna fuck me just 'cause you wanna?"

To my surprise, Andrea spoke next. "Riley, I love the feeling of Fuckhole here around my dicks, but if I want my dick sucked there's only one insanely-slutty five year old I think can do the job."

"Really? You like my blowjobs that much?"

Andrea gave a big nod. "And my friends love fucking you too. And all your friends at school, it sounds like. And what if Fuckhole doesn't want to have sex? She's a person who can turn me down - you're still a person for now, but there's no way you're gonna stop me from pounding your ass inside-out."

After hearing everyone's encouragement, I just couldn't stop smiling! I ran over and hugged Andrea as hard as I could, though I discovered that hugs with a big pregnant belly were quite tricky - I settled for a quick, sloppy, passionate kiss with my big sister instead.

With our naming and encouraging done with, our lives very quickly returned to normal. Mama hopped up and began to make lunch for us all, with Cocksleeve still napping happily on her dick. For lunch we had big, delicious sandwiches - though mine were filled with Mama's fat logs of shit, which she pooped directly onto my plate. At the same time she filled a tall glass for me with her piss, her golden stream pouring out of Cocksleeve's mouth as it passed entirely through the girl's body.

Mummy let me sit on her lap while we ate. She gripped me under the armpits and lifted me up, letting her dick slide straight up into my womb - Cumslut eagerly wriggled around to start sucking her dry. Halfway through one of my shit-filled sandwiches, as I watched Andrea and Mama use their babies as onaholes to cum all over my food, a thought occurred to me.

"Mummy? Where's Urinal?"

"Wanna take a guess? She's closer than you think."

I looked up at her, frowning in confusion. Urinal was definitely not on her dick, otherwise she would have ended up inside me. She could be lying on Mummy's bed or something, but then she wouldn't be very close at all ... where would Mummy put her piss-obsessed baby, then?

Leaning back a bit, I felt an odd lump in Mummy's belly. It was almost the right size for a baby, but weirdly low... "Oh! She's in your bladder?!"

"Clever clever!" Mummy gave me a pat on the head before grabbing me under the armpits to start fucking me. "She kept trying to pull me open, and ... well, I got a few biomods of my own while you were tied up. Rather than buy cribs, Mummy got her holes made stretchy enough to have babies sleep inside!"

I hadn't really thought about that before - I had a fully grown baby inside me, but of course a piss-loving toilet slut like Urinal would love to take a nap completely submerged in her favourite substance.

"Oh. Yeah, I didn't think of where the babies would sleep." Andrea looked startled. "I kinda just thought I'd keep her on my dick."

"You can if you want, sweetie. Or we can get you modded too, and make a crib of you."

Andrea looked down at Fuckhole, cum dripping from her mouth and bloating out her womb. "That might not be so bad... I could keep her inside me while I'm at school, too."

"I'd be tempted to do the same," Mama added, "But I think Cocksleeve is quite content on the outside, don't you think?"

Sure enough, the girl in question was once again fast asleep, more than comfortable being worn as a cock accessory. My jealousy flared up just a little, but I kept it in check as much as I could - after all, if Mama was going to keep Cocksleeve there as much as possible, there was every chance that the girl would end up back inside me, one way or another. I'd already had a much larger girl crawl inside me while I was bound up in public - getting fucked with a baby cocksleeve was no problem at all.

I was definitely happier having lunch with my family doubled in size, though. Sitting on Mummy's lap as she gently fucked me, eating my shit sandwich, and feeling Cumslut living up to her name by desperately attempting to drain my mother dry while inside me, I soaked up the atmosphere of a life full of sex. It wasn't quite a sex toy's life, but it was nice all the same. There are plenty of times where I miss those nice days with family, but nothing compares to being a sex toy! Even lovey-dovey, calm and quiet moments of sex that would be utterly depraved by the standards of your world!

After lunch, Mummy and Andrea used me as a toilet. Seeing as I had just had my share of Mama's poop and pee, I thought it best to let them fill my womb with my waste to feed Cumslut. I laid on my back next to the couch and flipped my legs up onto the seat before pulling my pussy open as wide as I could. Mummy went first, squatting over me and letting a thick turd slide free from her asshole and straight into my womb.

"Y'know," Andrea looked down at me with a grin, "I didn't mind being a toilet for our mums while you were gone, but I'm glad you're back. No more hefty, piss-and-shit filled belly for me!"

"Oh, really?" Mummy's hefty chocolate log dropped smoothly into my waiting toilet of a cunt. "Says the girl who asked us every night if we needed to use her before going to bed!"

Andrea blushed, hiding her face with her fringe as she tried her best to keep her cool composure.

"I-I was just... J-just making sure you didn't wake me up, is all!"

"Sure sure, sweetie. Toilet's all yours, by the way."

Mummy stood up, shuffled forward slightly and dropped her asshole down to meet my face - I quickly stuck my tongue inside, licking her clean as quickly as I could. Once she was satisfied with my service, Mummy hopped up and walked away without another word. I was all ready for Andrea to take her place, but my sister stood there with a slightly puzzled expression.

"How exactly am I gonna pee in you like this ... ?"

Andrea had a hand around Fuckhole's waist, slowly dragging the tiny baby up and down her twin shafts.

"What's wong, Andrea?"

"Well... If I take my cock out of Fuckhole, she'll get grumpy ... and I don't mind peeing through her, I did that before, but I don't want to fill her womb with my piss."

"Hmm..." I thought about it for a bit, before hitting on the obvious solution. "Why not fill her, then squish it outta her belly into me? Easy peasy!"

Andrea shrugged. "S'pose that works. You're way too clever, and horny, for a five-year-old."

Squatting down, she pressed Fuckhole's mouth to my open womb. With a grunt of effort, Andrea pressed her hips forward and let our daughter's face sink into my lips until her entire head vanished into me. I squealed in delight at the feeling of being stretched out, like I was giving birth in reverse, and I could feel Cumslut wriggling up from her self-fellating position to meet her sister. I wasn't sure exactly how I could tell, but I knew both of my daughters were kissing, Cumslut's head pushing out of my cervix far enough to lock lips with Fuckhole as the pair passionately made out. Andrea didn't seem aware of the exciting reunion going on inside my cunt as she let loose her stream of gold.

Warm, delicious pee flowed through Fuckhole's body, pouring up her neck and into Cumslut's mouth as she chugged every last drop down. At the same time, Andrea's other dick slowly rounded out Fuckhole's belly as her womb filled with piss. By the time my big sister was done peeing, Fuckhole's sloshing womb nearly obscured her entire chest. Andrea gently wriggled her head back out of my cunt and sat back on the couch, extracting her daughter from her dicks to drop her pussy lips down to meet mine. Even before she could reach my hole, Fuckhole managed to leak her hefty load of urine, splashing all over me as Andrea positioned her. I reached up and pressed on the baby's belly, delighting in the feeling of another torrent of pee pouring into me. I could feel Cumslut, now fully back in my womb, sucking the pee directly through my cervix. As soon as she was done being emptied, Fuckhole went right back to where she belonged - stuck on Andrea's twin dicks.

Andrea hopped up from her seat and began to walk away, stopping briefly to look back at me.

"Thanks, Riley."

"Just doin' my job!"

"Well, if you really wanna do your job as a toilet, well..."

Andrea gave me a mischievous smirk, and I raised my eyebrow.

"Mm? What? Tell me!"

"It's just ... with our mums using me as a toilet, I didn't have anyone to use myself, so ... there's a bit of excess in my room. Maaaybe, a cute little toilet could come and clean it all up?"

I scrambled to my feet, moving as fast as my legs could take me with a pregnant belly full of other people's waste and one very horny baby, racing a giggling Andrea to her bedroom. What I saw before me would look to anyone else like a disaster zone - to me, it was a treasure trove.

"Th-there's so much poop!"

Everywhere I looked were signs of Andrea relieving herself without a care in the world. I could almost imagine my big sister starting off the week trying to keep it vaguely tidy, like the way she piled her favourite shirts on a chair in the corner, or let her homework make a dusty stack on one side of her desk. However, by the end of the week, Andrea was certainly beyond the point of keeping things clean. On her bed and under her desk was the majority of her waste, though there were long, trailing piss stains across the floor, on some of the walls and, yes, even all over the shirts on the chair.

"Ah, yeah," Andrea looked a little bashful, catching me staring at the damp garments, "I couldn't decide which one I wanted to wear, or if I wanted to wear one at all and, uh, by the time I finished choosing I realised I'd kinda just peed all over 'em. I actually kinda like the smell now, and so do the girls, so ..."

Still, my eyes kept drifting back to those two hotspots of activity. Clambering up onto the bed, I inspected the situation. The sheets were drenched with pee, likely from our mums coming into Andrea's room in the night and urinating on her while she was asleep, or even Andrea just letting loose in her sleep. The scent drove me wild - I grabbed a fistful of the sheets and sniffed them deeply, enjoying the comfortable scent of my sister and the powerful musk of my mothers' urine.

All across Andrea's pillow were the remains of our mums' nocturnal visits, fat logs laying across the pillow, most of them half-eaten or at least broken in half from where they had been deposited on Andrea's head ... or were squished under her as she slept. Halfway down the bed was a massive pile of shit, almost certainly sourced from Andrea herself. Given the amount of poop my mums must have been stuffing her with, she was likely more than happy to let it all slide out constantly as she slept.

I stuffed myself under the blankets, taking the poop-covered pillow with me into the dark, damp cave of Andrea's toilet of a bed. My eyes blinked as I tried to adjust to the darkness, but my hands and mouth were faster - the huge mass of shit under there acted almost as a bed of its own, still retaining much of the heat of Andrea's body and giving me enough space to literally recline in it even as I shoveled bits into my mouth. Even though I was full from lunch, and Cumslut was almost certainly just as filled up with the shit I had in my womb right now, my urge to do my duty as a professional sex toy and toilet drove me to eat as much as I could.

... at least, that's what I told myself. You see, I had made a rather critical error crawling in here. It was dark, warm, and comfortable lying in this warm mass of my sister's shit, and the overwhelming sense of comfort and safety quickly met up with the fatigue of giving birth earlier that day. I hadn't slept in a bed the entire week, my body restrained and fucked constantly. I managed to stuff a fat log of shit into my cunt and another down my throat before my eyes grew heavy, and by the time I had filled my hands again I was completely asleep.

After the biggest week of my life, five-year-old Riley Evergreen crashed in the way only a girl that small can. I don't remember much more of that night, except for some brief flashes of consciousness - cocks sliding into me to use my holes as a toilet, Cumslut eagerly sucking herself off inside my womb, a fresh layer of warm, chocolate-rich shit finding its way onto my head as my sister slept above me ... then, morning.

When I woke up, I didn't feel groggy-eyed or tired - I was completely awake from the moment my eyes were open. Suddenly aware of my surroundings, it took my brain a moment to catch up to where exactly I was, for all the context of my life to fill in what was going on. I remember distinctly lying there for a few minutes, enjoying the sheer comfort of my situation. Cumslut woke with me, my horny little daughter rubbing her cock against my insides.

A log of shit was working its way into my mouth at an extremely slow pace - looking up, I realised that Andrea was still fast asleep, her asshole wide open around a piece of waste she had likely been emptying into me all night. I gulped up that log, realising that I had emptied my own bowels of waste straight back into the pile on Andrea's bed to make room. Thinking nothing of it, I did what I was trained to do - I cleaned my sleeping sister's asshole with my tongue, before crawling out from between her legs and back into the waking world.

I realised after a moment something was missing. Looking back at Andrea, I tried to figure out what it was. I drank in the sight of her thin, scrawny body, the way her chest rose and fell as she slept, the creeping erection of her twin cocks as they prepared for the day... a-ha! That was it! Fuckhole was missing! None of Andrea's body was bulging out, and I knew she hadn't been modified to have the girl inside of her yet, which could only leave one place for my daughter - with my mums.

Careful not to wake my sister, I crept out of Andrea's room and into my parent's room. It must have been quite early, both of them fast asleep and happily tangled together. I wormed my way into the blankets at the foot of their bed and shimmied my way up, using what little light I had filtering through the blanket to find where my daughters were sleeping.

Both of my parents were curled up close together, my Mama playing big spoon to Mummy's little spoon. Mama's thick cock was buried deep inside Mummy's pussy, rock-hard even in her sleep. Looking closer, I realised a small set of legs were sticking just out of Mummy's pussy lips, and I realised I'd just found Cocksleeve. My beautiful cock-accessory of a daughter had been so content to continue being a part of Mama's cock that she had been used almost like a condom, just an extra bit of texture to enhance Mummy's pleasure. On the other side, Mummy's soft cock laid in a pool of nearly dried cum, the pearly liquid splattered across the lump on her belly and down her unusually distended testicle.

Getting closer, I ran my hands across both of those unusual lumps. As expected, I could feel the shape of Urinal where Mummy's bladder was - I expected the girl had decided she had her home for now, and only the promise of more solid food would be enough to entice her out. The bloated testicle was also not exactly a surprise. Andrea must have decided to leave her daughter with our mums, little Fuckhole more than happy to squirm down Mummy's enhanced dick to spend the night in one of her balls. I stared for a long time, gently stroking my daughter's head through the skin of Mummy's balls, thinking about how wonderful it must be to live in there. My thoughts drifted to my school friend Dana, and her heavy balls full of incredibly delicious cum. I wondered to myself, if I ask nicely enough, will she let me live inside her?

"Riley...?"

Mummy's voice snapped me out of my thoughts.

"Hi, Mummy. I'm saying good morning to the babies."

My mother graced me with a soft, dreamy smile. I didn't quite understand the expression at the time, but I do in hindsight - my mother was thinking of her big, happy family, how it had grown suddenly so much bigger... and how it was soon going to get even larger.

"Mm... Riley, let me use your pussy, sweetie."

I did as I was told, crawling further up the bed past Mummy's stiffening cock to flop onto my side against her chest. With my back to her, I made an even-smaller spoon to the already big and little spoons on the bed. Mummy hugged me softly as she slipped her cock straight up and into my womb. Cumslut shuffled around inside me as soon as she realised Mummy was peeing into me, slurping up her morning drink and getting in position to catch the impending wave of cum. Mummy fucked me softly and slowly, enjoying the feeling of Cumslut licking the end of her shaft, the tossing and turning of Fuckhole in her balls, the eager slurping of Urinal in her bladder, and even the simple presence of Cocksleeve stuffed all the way up into her asshole. When she came, Mummy gave a soft, sighing moan and stroked my head.

"I love you so, so much, Riley. You're going to make an excellent sex toy."

"I wuv you too, Mummy."

Later that day, we made a trip to the doctor. Just because our birthing ceremony had been a little unorthodox compared to the sorts of things in your world didn't mean we didn't need to have check ups on the new babies. They had to be registered, checked they were healthy and, possibly more importantly, to see how many of my own modifications has passed to them. The entire family made the trip too, if only because we were each a parent to at least one of the children present - Andrea grumbled about having to cancel on some plans, but she happily made use of Fuckhole's enthusiasm for incestuous sex on the entire car ride over, and for the entire time we were stuck in the waiting room.

Oh, the waiting room! We were certainly a sight - do I need to remind you that this is not a common way of having a family, even here? Sure, marrying a child and even having a kid with her is uncommon but not anything to gawk at, but we were something else. Before we left, Mummy had returned Fuckhole to Andrea by ejaculating her out. That was a process I didn't mind helping with - I gave her one of my bestest, super strong blowjobs, my head bobbing as fast as it could go, before her balls squeezed and a baby-sized lump started pushing its way up Mummy's cock. Mummy's cockhole hung wide and open for nearly half an hour after that, slowly returning to its normal size.

Cocksleeve was happily awake and babbling on Mama's shaft, and Fuckhole was bouncing on Andrea's lap, but Mummy realised that she was going to have to remove Urinal too. Squatting in the doctor's waiting room, I slurped up my mother's excess piss as she attempted to push the baby out of her bladder. There were a couple of other families there too, and one girl a couple years younger than me wandered over to see what was happening.

"What's that?"

The tiny girl, naked except for her curly brown hair cascading over her chest, pointed at the slowly moving lump passing from my mummy's bladder to her cock. Mummy's pee had been entirely blocked up by Urinal coming out, so I was able to take my mouth off her cock to explain.

"That's my daughter, Urinal! She was taking a nap inside my mummy, but now she's gotta come out an' say hi to the doctor!"

"Baby? Woaaah!"

The girl started shouting as Urinal's head crowned out of Mummy's bulging dick, and I caught the tiny, soaked baby in my hands. She looked around, blinking and confused, her arms stretching out to hold my fingers as I cradled her. Then she started crying.

"Why's she sad?"

"Urinal really likes pee, but she can't stay in Mummy's bladder forever. That's where your pee is, your bladder!" I tapped the girl on the belly, where her bladder was, so she could understand.

"I can pee! Don't cry, baby!"

Gently, far more gently than I expected from such a young girl, she pulled my hands so I could lower Urinal to her puffy pussy lips. Urinal seemed to get the idea, locking her mouth onto the toddler's urethra and slurping up her golden nectar. I couldn't help but notice my daughter's belly was quite round, and she sloshed a little when she moved - my greedy-guts of a daughter was crying even with a full belly of piss!

The doctor called us in not long after, and I said goodbye to the nice little girl. I watched her head back to her mum, a woman a little older than Andrea who had been gently masturbating a foot long shaft to the sight of it. I caught the start of a conversation before I headed into the doctor's office.

"Mummyyyy, I wanna baby!"

"Sweetie, I don't have anyone to have a baby with right now. I-- woah!"

"Baby in me, mummy! Gimme!"

"... Oh, geez, fine. I suppose if that family's knocking up their daughters so early..."

The doctor saw me first - or, really, she wanted to see the baby still inside me.

"It's been a while since I've seen a case of birth reluctance in a girl your age," the doctor smiled at me, pressing a cold stethoscope to my round belly. "It must be very comfy in that womb of yours, huh?"

"Mhm. Cumslut loves it, 'cause I'm a sex toy so she gets lots to eat and drink."

"Cumslut, was it? Certainly an... interesting name. I'll get that written down on the birth certificate while you hop up onto the examination table, okay? Oh, and I might have to look inside you a little bit, is that okay?"

With mama's help, I clambered up onto the padded table, and looked up in awe at all the strange machines around me - things with buttons and gizmos, flashing lights and tentacle-arms, all the kinds of things a doctor might need to look over a five-year-old girl and her baby who refused to be born.

"Mm, I'm real stretchy," I answered the doctor's question. "'Cause I'm a sex toy. Well, I'm gonna be a sex toy, when I finish my training!"

"Oho! That'll make things easier. I was going to send my machines inside, but that can be a bit delicate ... would it be alright if I poked my head inside your womb, then? Hands too."

If the woman had suggested that she crawl her entire body into my womb, I would have agreed instantly. I probably wouldn't have survived that kind of insertion as I was then, but I would have agreed to it. The doctor tied up her hair into a special plastic cover, scrubbed her hands clean and turned me around so my legs were dangling over the side of the table. I think I realised just how much bigger the doctor was compared to me as she sat there, preparing all sorts of little tools and bits - growing a bit nervous, I held Mama's hand as the doctor prepared to dive inside me.

She started off with just a few fingers, like she was fingering me. Slowly rubbing my clit with her thumb, she moved in a way that reminded me of the lady from the start of my journey to being a sex toy - careful, always checking I was okay, ready to stop at a moment's notice. When she figured I was suitably lubricated, her hand slid inside me ... and that's where the comparison to my first sexual experience ended. The doctor seemed far more acquainted with the kinds of limits a girl like me might have, her hand sliding straight up my birth canal and into my womb. Cumslut stirred, curious. I could see the doctor's hand, feeling around inside me as she inspected my daughter, and as Cumslut inspected this strange intrusion right back.

"Arms and legs feel okay, healthy amount of movement... slight swelling in the abdomen. Vagina is... pliable, as is the anus. Wow, she's very active!"

I couldn't help but nod. "Cumslut's super horny like me! She loves being touched, lots!"

"I can tell... Riley, I'm going to crawl inside you now. If you need me to come out or if anything starts hurting, just shout out - I'll hear you."

Little Riley Evergreen, invincible size-queen, nearly rolled her little eyes. "I'll be fine. Go inside me!"

And go she did. She pulled me open so far that I went cross-eyed, orgasming on the spot... and then pulled me open more. Any normal girl would have been torn in half - my training and modifications helped me immensely. Taking several tools with her, the doctor shoved in her other arm first, before prying open enough room for her head to fit cleanly inside. I was pulled open nearly as wide as her shoulders, my pussy a tight, thin ring around the doctor's neck and arms. I could see her moving around inside me, spraying her bare back with my pee as I uncontrollably orgasmed from the entry. But I didn't shout out - it felt so good to have something so large inside me. I was seeing stars in my vision, but my dreams expanded well beyond them. If I could fit her inside me, what else could go in there...?

The doctor spent a full ten minutes inside me, her arms shuffling around to inspect Cumslut inside and out. Through our nebulous connection, I could feel the doctor testing her with all kinds of strange equipment. She even shoved her fingers inside Cumslut's holes, testing her responses to various sexual stimuli - things I saw more clearly on my other daughters, but could feel more viscerally on Cumslut in my womb. When the doctor emerged, my pussy hung wide open - but I could feel my cervix slamming shut, protecting Cumslut from the light of the outside world.

"She's perfectly healthy, Riley. Or, should I say, grandmother."

It took a moment for me to realise what she was saying, but my face blossomed into a smile so wide my cheeks started to hurt.

"I knew it! Cumslut's pregnant, mummy!"

"And, all of her holes are well-used. If I had to guess, likely by her siblings."

The doctor looked around at the rest of my daughters, at the hard little cocks all three of them sported. I knew, though. That's what they had been up to, the day before the birthing ceremony - making absolutely sure their sister was pregnant before they all left on their own journeys.

"It'll take a while for the results of the modification inheritance survey to come back, so lets have a look at the rest of them, shall we?"

Fortunately - or unfortunately, depending on your preferences - the doctor did not need to crawl inside anyone else to get a look at the rest of my daughters. Andrea and Fuckhole went next. My daughter/niece was rather well-behaved as she was lifted up off of my big sister's dicks to be inspected, blinking in curiosity as the doctor prodded her here and there. I got to watch what had been done to Cumslut inside me, the doctor shoving her fingers into Fuckhole's pussy, her anus, even her urethras, all to inspect how easily her hands slid inside. She used a variety of tools, fed data into her computer, and turned back to us. She confirmed for us what anyone with half a mind for cause and effect could have figured out.

"Little Fuckhole here is also pregnant," the doctor smiled brightly at Andrea. "The pregnancy won't be affected by any further sexual activity, so feel free to continue having sex as much as you both like."

Andrea had turned pale.

"W-Wait, I'm gonna be a mother again with my own daughter?"

"Tell me, young lady, just how much have you been cumming in her womb?"

"U-Um..." Andrea looked down, suddenly sheepish. "Like, hourly? I've been fucking her constantly since she was born..."

"And there you have it! If you both would like to not have any further children, we can sort out a modification. Otherwise, you've got another little bundle of joy on the way."

Mama laughed.

"Oh, Andrea, having a kid with your own daughter isn't that bad!"

We all turned at looked at Cocksleeve, still napping soundly around Mama's dick. Andrea grizzled and groaned at the rest of us laughing, but I could tell she didn't mind. Especially with the way her cocks twitched, eager to be back inside Fuckhole's tiny body. To cover for her real feelings, she invited me over to sit on her lap - I let one of her cocks slide up into my womb for Cumslut to play with while I massaged my sister's shaft. I even figured I could sit astride one of Andrea's legs and help Fuckhole with her never-ending quest to slide up and down her own mother's thick cock. The steady rhythm of bouncing my own pussy up and down as I used Fuckhole's little asshole as a sex toy let me turn my thoughts back to the other two of my daughters as they got their inspections.

Surprisingly, Cocksleeve wasn't pregnant. Maybe it was the fact that Mama's cock barely left room inside the tiny girl for another life, or how Mama had only really been using her daughter's asshole and mouth. But, what we did know was that Cocksleeve hated being parted from Mama's dick. The moment it slid out of her fully, the girl started to cry - the doctor tried her best to calm her, but realised that the only thing she wanted was to have her entire being converted into a warm, tight wrap for a dick nearly as big as her. Instead, the doctor hurried through her tests before gently returning the wailing baby to her rightful place.

"Your daughter is perfectly healthy," she smiled, petting Cocksleeve on the head. "In fact, going by the readings I was getting, her body has adapted itself to your penis."

"Adapted?" Mama frowned. "What do you mean?"

"It's usually only possible with extensive modifications, but a combination of her modification inheritances and the fact that she has spent so much time wrapped around you like that has led to her body altering itself. In fact, as she is, she could live out her entire childhood with your dick inside her without any physical issues. I suspect she might even prefer it!"

Mama grinned, holding Cocksleeve in her hand as she slowly jerked herself off. The tiny girl looked so peaceful and content, completely dwarfed by the sheer thickness of Mama's powerful shaft - I think Mama liked that idea too.

"I'll think it over. What do you think, honey?" Mama turned to Mummy with an almost ridiculous grin. "Cock enhancement modifications for her birthdays, to keep her on for longer?"

Mummy laughed. "I might enjoy that too, you know?"

Last but not least, Urinal was inspected. The doctor made a few jokes about the fullness of the girl's belly - my sweet little sister/daughter was still absolutely sloshing from all the pee inside her from earlier, even after having flooded Mummy's chair and the floor around her with the excess. But, by the end of it, Urinal was pronounced healthy again... and changed, just like her sisters.

"I'm starting to get back the modification inheritance results, and there are some surprisingly variable results here. It seems little Urinal got a somewhat enhanced version of her mother's waste processing modification - the girl can derive her entire nutritional needs purely from urine, though she's also capable of processing feces, in addition to normal food for a girl her age. In addition... her lungs have been altered to process oxygen from urine! That's not a standard modification, not by a long shot - in fact, it's a rather surprising mutation. She doesn't just drink urine to live, she can also breathe it!"

The doctor was starting to look quite excited - I didn't understand it at the time, but she was finding something more exciting than a bunch of horny kids today. The itch to understand had completely overtaken her, and she turned to me for answers.

"Riley, out of curiosity, did you eat, drink or take anything strange before you were impregnated-- before everyone had sex with you? An odd food or drink, a new medicine...?"

The gears turned in my brain as I mentally tracked back through the entire week of excitement, but Andrea got there well before me.

"Oh crap! The multi-partner solution... solution!"

It took me a moment, but I remembered it. The strange drug I had taken so that my mums and sister could each impregnate me separately. I hadn't thought much of it, but Andrea was now realising just how strange the whole thing was - the sketchy, hand-written note about signing up to 'trial' it, the unusual website, everything. Andrea took over for me, explaining to the doctor everything. The doctor took us very seriously, even when I chimed in to say that it was 'super duper cool' and 'my mummies and my sister had babies with me, not just one!'

After everything, the doctor handed my mums a business card for a colleague of hers that would be interested in studying my daughters and their strange modification mutations. Personally, I thought they were amazing, the kinds of things that everyone should have. The doctor agreed.

"If we can understand what happened," she explained, stroking my head as slid her cock down my throat, "Then lots of other girls who want to live just like your daughters can get modified to be just like that too! I don't know where you got that drug, but my friend would be super happy to talk to them, to help out with making things like this a reality!"

I nodded, attempting to voice my approval as the doctor used my sex-toy mouth for its intended purpose - I meant to say something like, 'That sounds amazing, what a fantastic idea, can't wait to let girls the world over experience such amazing abilities like being able to live their lives impaled on their mother's fat cocks or submerged in someone's bladder'. Instead, it came out something like, "Mmmph! Mm-mm!!"

She got the idea, and my stomach got filled with a nice helping of warm cum. All in all, a fantastic trip to the doctors, and a wonderful way to welcome my daughters to the family. But even a young mother of four like me couldn't avoid reality. As soon as the weekend was over, it was time to go straight back to school. To take my heavy, pregnant belly back to my regular classes, and my special sex toy classes too.

I couldn't wait.
