Makoto scribbled three doors on a piece of paper again. "Okay, so the odds for a door to be the correct answer is one-out-of-three for each door, right?"
"Come on, I don't want to go this again, you know it confuses me." Komaru said with a groan.
"It's a simple statistics problem!" Makoto replied, baffled and hurt that Komaru, who was actively taking a statistics class, still didn't get this. "It's the most famous statistics problem ever! If anything, you should be explaining it to me."
Komaru groaned. The two of them were busy studying at a cafe near their house, with Makoto helping her with her work, since she disliked doing it. "Yeah but I can't seem to wrap my head around it."
"Okay, let's try a different assignment," Makoto offered, digging through his bag and pulling out a pink notebook. "Only one problem with my notes, however."
"What's that?"
Makoto flipped the notebook open and showed that, in several pages, elaborate notes had been drawn over with scenes of incredible sexual depravity. "I know you love drawing, but your drawing practice is covering up my Civics notes."
Komaru snickered, and then when she looked up, she was stunned by the way somebody seemed to be running towards them. "Uh, Makoto?"
Rantaro bumped into the table, steadied it, and let out a long exhale. "Hello, Makoto. This must be your sister, Komaru."
The other male shocked Komaru by leaning down and kissing the top of her hand. "A pleasure to meet you, your brother speaks highly of you."
"U-Umm…" Immediately, the girl became flustered and her cheeks burned. "M-Makoto? Who's this?"
"Ah, Rantaro!?"
"Hey, Makoto, I need some help." Rantaro said.
"W-we're a little busy…" Komaru said, unable to tear her eyes away from the…strangely attractive boy.
"Nonsense, c'mon, sit down," Makoto offered the clearly exhausted underclassmen.
"I, uh, have had a busy week. And a stressful one. You seem like a really nice guy, so I need some advice," Rantaro rambled on, sounding both incredibly energized and a few moments away from passing out at the same time.
"What is it?" Komaru asked.
"Have either of you ever been in love with someone you weren't supposed to be in love with?"
Makoto's jaw dropped.
"Uhhh…umm…y-yes?" Komaru said. Makoto slowly turned to her in horror as Rantaro's eyes lit up.
"Really!? Tell me more, please!" Rantaro exclaimed.
Komaru glanced at Makoto and then cleared her throat. "I-I'm not sure if I…want…to."
"Y-y-yeah…that kind of thing can be very personal-" Makoto was cut off by Rantaro lunging across the table and grabbing his hoodie.
"Please!!! Makoto, Komaru, I am going insane. I've been to three therapists, a chiropractor, a priest, an uncle I only learned existed from a DNA test, and a homeless man who disappeared halfway through our conversation. I need help!"
A barista dropped off Makoto and Komaru's drinks at the table, patiently listed Rantaro's order for a cold brew with eight expresso shots, and marched off.
The boy settled back in his chair a bit. "Sorry for the sudden pressure…I'm a bit…y'know."
"Makoto? Should we…?" She asked quietly.
"We can listen," Makoto offered. "So, who is it?"
"That's the thing…I can't say."
Makoto took a sip of his mocaccino. "So, you see how that kind of puts us in a bind, right?"
"I know..."
"I…um…look." Komaru said. "From my experience, what I've learned is…" She tried to find the right words, "…as long as it isn't…illegal…and you are careful about it…I think it should be fine for you to…love who you love?" Komaru looked to Makoto to see if he agreed or approved.
"Yeah!" Makoto declared, latching onto that bit of seemingly easily positive affirmation. And yet, Rantaro seemed a bit saddened.
"But…what if it isn't?"
"Can you please just tell us? Seriously, we won't judge you. I mean…I barely know you so…" Komaru said. Before he could tell them, the waiter brought his drink over. Rantaro took one major sip, yelped, and fell face first onto the table, motionless.
Makoto reached over and pressed his fingers against the side of Rantaro's neck. "He's not dead, but that much caffeine will have him out for the next few minutes at least."
"Okay, so…do you think he's…the same as us?" She asked quietly, just in case.
Makoto shrugged. "How would we even explain that if he was?"
"I dunno, I just…" Komaru trailed off as Rantaro began to mumble in his sleep.
"Ami…sho pretty..."
"Nobody by that name goes to Hope's Peak." Makoto said, and Komaru waited for if he would say more.
"My pretty little sissy..."
"I KNEW IT!" Komaru cried.
Makoto looked around to confirm that no one else really cared before looking back to Komaru. "Okay, so, what should we do?"
"Um…invite them over and hook them up?" She offered, half-joking.
"No way, just because that happened with Monaca does not mean this is becoming a consistent thing."
"Come onnnn…are you saying you don't want to help out someone with their forbidden love, yet keep enjoying your own?" Komaru asked.
Rantaro's entire body jolted and his eyes shot open. "She's my sister. My little sister. I love her so much."
"Ah!" A-are you…awake now?" Komaru asked, jumping in her seat a bit.
"I am more awake than I have ever been. The doors of infinity have been opened and I see through them like an anglerfish sees its prey in the deep."
Makoto awkwardly chuckled as he got out of his sleep. "I…think you need some actual sleep, Rantaro." Komaru reached over and slapped him across the face. Not super hard, but hard enough.
"Nothing you do can hurt worse than what this love has done to me." Rantaro said softly.
Makoto picked Rantaro out of his chair. "Look, we'll help you."
"REALLY!?"
Makoto winced. "Yes, just, get some sleep. We'll talk more when you're…lucid."
The two told him where they lived, even writing it down in case he forgot, and then awkwardly left Rantaro there in his weird state of being, hoping he would get some good sleep.
The next day, Komaru and Makoto were sitting watching TV when they heard a knock at the door. "Already?" Komaru asked as she stood up. "I can't wait to see his sister. He said little sister, so I wonder how much younger she is. Did he ever mention her to you?"
"No? I'm sure she's, like, a high schooler. Could you go get the door?"
Komaru nodded, walked over to the door and opened it with a smile on her face. That smile froze when she saw Rantaro…and a small child standing next to him.
"Ami, this is Komaru. Can you say hi, Ami?"
"Hi!" Ami, Rantaro's little sister said with a huge grin and a wave. She was a small girl with long green hair that matched her brother's.
"Oh…boy…" Komaru said with a nervous laugh.
"Well, Komaru, let them inside!" Makoto called out.
"S-sure. Um…follow me." Komaru said awkwardly as she led the two into the living room. "Makoto, this is…Rantaro's sister."
"Hiiiii!" She said again as she gave another wave.
Makoto's entire body froze up as his voice squeaked. "Hi-"
"Here, Ami, you can go watch some TV in the other room they set up for you and me." Rantaro explained as he herded his very little sister into the guest room Makoto and Komaru had told him about.
Komaru walked over to Makoto. "Um…"
"She seems older than Monaca…but so much more innocent..."
"She's like half Rantaro's size! That dick would destroy her!" Komaru said, glancing at the girl as she ran down the hall.
"I mean, did you think he was that big?"
Komaru froze as a deep blush ran over her face and she cleared her throat. "I-I…might've been…thinking about him during our…session last night…"
Makoto immediately pouted. "What, am I not good enough anymore?"
"No! I-it's just…" She glanced at the boy, who smiled and waved at her. "He's…really hot."
Rantaro returned soon after, Ami being left behind in her room. "Thank you two so much for this! I don't know what I'd do without this help."
"You…didn't tell us what Ami was like."
"Well, isn't it obvious? She's the most beautiful girl in the world, perfect in every way. I love her more than I could express."
"Right…umm…if I may ask…have you…done anything with her in the past?" She asked apprehensively.
"Nothing, although I think I've loved her since the moment she was born."
Makoto gagged a little. "That's…nice..."
"Look, Makoto, we can't judge too harshly after Monaca." Komaru said, and then turned back to Rantaro with a large smile. "We will do our best to get her to see you the way you see her, starting with Makoto going and having a talk with her!"
"What!?"
Komaru grabbed Makoto and started leading him to where Ami was. "Have a talk with her, see how she feels about Rantaro, don't have sex with her, good luck!" She exclaimed as she pushed him into the room.
Makoto had to concede that 'don't have sex with her' was probably a necessary bit of advice to keep in mind as he approached the petite girl, who was sitting on the bed and flipping through the TV. "Hey, Ami," Makoto cooed in his gentlest tone possible.
"Hi! What's your name?" The little girl asked.
Makoto sat down next to her, carefully putting distance between them. "I'm Makoto, I'm a friend of your brother's."
"Any of big bro's friends are my friends!" She said, moving over and giving the boy a hug.
Makoto shuddered a bit as she held onto him. "So, you really love him?"
"I love him a whole lot!" Ami said with a wide smile.
Makoto started fumbling over his words as the girl refused to let go of him. "A-a-and what would you do for him?"
"Anything!" She said as she squeezed him tighter, not noticing how he was reacting.
"Even if it scared you?"
"Scared me? What could big bro ever do that would scare me?" She asked in confusion.
Makoto rubbed the top of her head. "Well, sometimes you…learn a lot, and what happens all at once can be a bit scary. You just have to trust your sibling, right?"
Ami just stared at him, confused.
"You trust Rantaro, right?"
"Yes." The girl said with conviction.
"Good! We're going to play a big game tonight, and you need to trust Rantaro a lot for it. Do you think you can do that?"
She nodded, and hugged him again, before another look of confusion came over her. "What's in your pocket?" She asked.
Makoto leapt off the bed and put a hand over his erection. "My wallet! Yeah, my wallet! Just, stay here. We have some more prep to do for the game. Understand?"
"O-oh. Okay! I like you!" She said with another wide smile. Makoto smiled at her before rushing out of the room and back to the kitchen, where Komaru and Rantaro waited.
"Were you able to resist her charms?" She asked, smirking. "I guess not." She followed up, seeing the tent in his pants.
Makoto frowned. "She's still Rantaro's, and I can say that for certain."
Rantaro's eyes lit up with almost childish glee, and he rushed across the kitchen to hug Makoto, not minding that the boy's erection pressed into his stomach as he did so. "Thank you so so so much!"
Seeing Makoto's bulge press against the boy's belly made Komaru shudder.
"So, what comes next?"
"Well, the most important part of all of this is making Ami feel comfortable. So we're going to play a basic card game, encourage her to get naked, we'll get naked too, and you can escalate things slowly from there. Does that sound good?"
"We could rig some strip poker!" Komaru said with a bright glint in her eyes.
"You know how to rig a card game?" Makoto asked.
"Rantaro, does she know how to play poker?" Komaru asked.
"I don't even know how to play poker."
"Yeah, Komaru has tried to teach me but usually she winds up jerking me off before we get anywhere." Makoto said.
"Good! That means we can lie to her." Komaru said. "It's just a matter of if she'll play along once we get…you know."
"Okay, let's do it. Just…remember to be slow. She's not Monaca."
"I bet you wish she was~" Komaru teased.
"I mean, Monaca is nice and all, but Ami is cuter." Makoto said.
"Thanks! If she's comfortable with it, you can have sex with her too." Rantaro said with a smile.
"Let's…take that as it comes." Meanwhile, Komaru's smile fell as her joke was completely overtaken.
The game was quickly set up at the kitchen table, complete with Komaru donning a green dealer's cap and Ami needing a custom high chair made of cookbooks. "Alright, Ami, have you ever played this game before?" Komaru asked.
"Nope! I've heard about it though." Ami answered, and Komaru smiled.
"Perfect~" She said, and then, being vague, she started explaining the game to her, trying not to mention specifically which hands would be better than others. Once Ami seemed to understand, they started, and Komaru dealt their hands.
"Straight flush!" Makoto declared as he laid a set of cards on the table that were definitely not a straight flush. Rantaro did the same thing with his 'triple.'
Komaru and Ami laid their hands down, and while Komaru claimed to have a straight, Ami wasn't sure what she had.
"That's a double, which means you have the lowest hand," Makoto gently explained.
"Oh…so what do I do?" Ami asked.
"But…mom and dad said we're not supposed to do that around other people." Ami said, looking at Rantaro.
"Don't worry Ami, the whole reason behind that is so you don't expose yourself to people who want to hurt you. I don't want to hurt you, do you think Komaru and Makoto want to?"
Ami looked over at the two, and after seeing their smiles, she smiled back. "If you say it's okay!" She exclaimed before swiftly pulling off her shirt, leaving her topless, as she was too young to even need a training bra yet. Makoto squeaked a bit. Maybe Komaru was right and he did prefer them flatter than usual.
Rantaro made no illusions about how he felt. "Ami, you look so gorgeous! You're so much prettier than other girls your age."
Ami blushed and smiled. "Thank you, big bro…"
A few rounds went by, with losses evenly divided. Komaru was left in her underwear, Makoto in his shirt and underwear, Rantaro was shirtless, and Ami was down to her panties and a pair of long socks. Komaru, being eager to get naked, as she was turned on by the whole event, claimed her hand was the worst, and quickly threw off her bra, her large breasts bouncing slightly as they were freed, and she discreetly looked over at Rantaro to see how he would react.
Rantaro, to her chagrin, winced a little in response before refocusing on Ami. "So, how do you feel, Ami?"
"YOUR BOOBIES ARE SO BIG!" Ami shouted at Komaru, who blushed deeply. "I want mine big like that!"
"W-well…maybe…you don't…" Komaru said, looking down at her chest as she started to feel insecure.
Rantaro chuckled and leaned over to pet his sister's head. "I think you look beautiful just the way you are~"
Makoto frowned a bit as he saw Komaru's dejection. "Well, next round?" Komaru started dealing the next round, and Rantaro, seeing how things were escalating, quickly got his pants removed, standing up close to Ami so that when his cock bounced free she could see it clearly.
"And Rantaro loses again~" Komaru said at the end of the next round, eager to see the boy's penis even if he had found her breasts disappointing. Rantaro giggled a bit as he wiggled out of his underwear, his average-sized cock bouncing rapidly as he shifted back and forth, pulling the fabric over his legs and tossing it to the side.
Ami's cheeks flushed as she stared at it in awe, though she didn't seem to fully understand why. "Wh-what's that?"
"That's his penis, most guys have them." Makoto said.
Rantaro pushed his hips towards his sister. "You can touch it, if you want."
"U-um…" She seemed hesitant as she stared at the strange organ, her body reacting on its own as her legs twitched and her thighs rubbed together. "I-I don't know if…"
"Hey, Ami." Komaru said, drawing her attention. "Why don't you go sit in his lap. That way, you can get more used to it." At that, the young girl's eyes lit up.
"Okay!" She exclaimed, and rushed over to Rantaro. Without a second thought, she jumped onto his lap and scooted back, his dick resting against her panties and back, which, while it felt a little weird, it also felt warm, reassuring the girl that everything was alright.
Makoto felt his cock aching through his underwear at the sight of it. "Komaru, next round?"
After another round, Makoto was left in just his underwear, joining Komaru and Ami, and once the next round was over and everyone had their hands down, Komaru smiled. "Alright, Ami, you lose~" Yet the girl looked uncertain.
"Are you sure it's okay?" The young girl asked her brother as she shifted on his lap.
"Of course Ami!" Rantaro panted with lust.
"Okay!" Ami said, trusting her brother completely as she stood up a bit to slide off her panties, kicking them to the side with glee. Once she saw back down however, she frowned as she felt his dick slide between her ass cheeks, the head still resting against her back as the skin of her bottom squished against his thighs.
Rantaro reached around to rub Ami's thighs, while also leaning down to whisper in her ear. "You look so gorgeous, Ami~"
Makoto concurred. "Yeah, you both look great!"
Ami shuddered, her face flushing. "This feels…weird."
"Why is that?" Rantaro continued, moving up slightly to her waist and stomach with his hands.
"I-I don't know…I just feel…hot." The girl said as her thighs rubbed together.
Makoto chuckled a little. "Well, if you don't mind putting the card game on a bit of a hold, there's something really fun you can do when you feel that way~"
"I-I think we should finish first!" Ami declared.
"Okay, but Komaru, be careful; Ami is winning!" Makoto declared with faux-shock and a wink.
Komaru dealt the next hand, and when she declared herself the loser, she stood up, facing away from Makoto as she slowly slipped off her panties over her ass, even shaking her hips a little as she did, until they were off, and she pretended to stretch by reaching down to touch her toes before standing back up, and then sitting down, giving Makoto a smirk.
Rantaro was so engrossed in Ami's body he didn't even pretend to play, his entire body shuddering as he stared down at his little sister with wide-eyed arousal and passion.
"Hey, Rantaro? Your cards?" Makoto asked.
"Yeah, uh, two sixes, or something..."
"…I guess it counts, next round."
Komaru felt even more disappointed that her little show hadn't even gotten a reaction out of her brother, and so she started the next round, where Makoto was the loser. Makoto stood up and quickly pulled his underwear down, only blushing slightly as his cock sprung free before quickly sitting back down.
"Alright, last round." Komaru said, sounding a bit dejected. "You guys ready?"
Makoto smiled at her. "Of course!"
"Yeah yeah yeah," Rantaro muttered as he reached up and groped what little 'chest' Ami had.
"B-big bro! Th-that tickles!" Ami said as the cards were thrown out.
"Looks like Komaru loses!" Makoto declared with maybe a bit too childish of a tone.
"And Ami wins!" Komaru said with a small smile.
"Yay!" The small girl cried. "What do I win?"
Makoto reached into the pocket of his pants, unable to suppress a giggle as he did so. He saw this in a video once and could never get the opportunity to try it, until now. When he came back to the table, he had a particularly sizable lollipop in his hand. "You like these, right, Ami?"
Ami's eyes went wide. "Woaaahhh! It's so big~!"
"And, if you still wanna learn some cool adult stuff, there's a special way to lick it. But you have to get off of Rantaro's lap first." Ami did so, excited to see what this 'adult' thing was, and she eagerly watched as Makoto came closer. Rantaro raised an eyebrow as Makoto placed the head of the sucker against the head of his penis.
"Now, Ami, give it a big lick."
Ami's smile fell a bit. "B-but…um…it's…against that…thing…"
"That's the point, it makes it so much more fun. And you trust Rantaro, right?" Makoto egged her on as Rantaro smiled at her.
"Y-yeah…yeah!" She said, her smile returning. "If that's what big bro wants!" Makoto watched as she leaned down and gave it the first lick, her tongue just barely catching the tip of Rantaro's penis and causing the other boy to let out a moan. At the noise, she leapt back. "D-did I hurt you?!" She asked, scared.
"N-not at all..." Rantaro exhaled.
"That's the fun part of doing it this way, you get your sucker, and Rantaro feels good. Komaru, don't you think this looks fun?"
Komaru, who was still salty about being ignored, sighed. "Yeah, sure."
Makoto frowned, but didn't realize the problem. "Here, Ami, you take the sucker and try it yourself. Lick Rantaro's penis, and then take a lick of the sucker."
"Sounds weird, but okay!" The girl said as she took the sucker from Makoto's hand, and held it up to Rantaro's penis as she slowly licked both of them, looking up at Rantaro to see if she was doing it right.
Makoto walked over to Komaru and sat down next to her. "Something wrong?"
"I shook my ass for you and you didn't even react at all." Komaru pouted, watching as Ami flicked her tongue both against the delicious sucker and along her brother's throbbing shaft.
Makoto blushed while Rantaro started panting like a dog on a hot day in response. "Sorry, I got a little focused on making sure this worked out."
Komaru turned away from him, huffing. "No, I get it. You like the flat chested ones more, I see."
Makoto smiled a bit and reached under her arms, roughly groping one breast while pinching her other nipple. "C'mon, you know how much I love you~" Komaru shuddered, but her pout still didn't leave her face. Makoto upped his assault as he craned his neck up to kiss the side of her neck. Komaru could feel herself starting to relent as her body betrayed her, shuddering as her hands clenched and unclenched.
Meanwhile, Ami was making steady progress on both Rantaro and the sucker, and she stopped for a moment to look up at him. "Am I doing it right?" She asked.
"You're doing amazing!" Rantaro gasped as he tried with all of his might to keep from painting his adorable little sister's smiling face.
"Hear that, we could be having that much fun~" Makoto purred as he reached between Komaru's thighs to rub at her clit.
"Nnnng…oh…f-fuck…" She gasped, leaning up against her brother as her chest heaved.
Ami smiled as she kept going, a bit weirded out by how the organ kept throbbing against her tongue, but she assumed that was normal, and kept going, attacking both the sucker and penis with ferocity. Rantaro gasped as his dam broke, a torrent of cum flowing from his cock to land directly on Ami's face, painting her with ropes of semen.
Makoto forcibly turned Komaru towards the sight. "Wow, Ami, great job!"
"AHHHHK!" She shouted, surprised as a bunch of white gunk erupted onto her face. "Wh-what…" She wiped some off of her face with a finger and looked at it. "It looks like snot."
"It's…not. In fact, it's a sign that you made Rantaro very very happy!" Makoto assured her.
"Yeah..." The other boy could only exhale as his body vented the most intense orgasm of its life.
Ami, reassured that it wasn't snot, was still curious about the cum. She sniffed it, finding it had no scent, before sticking it into her mouth and licking it off her finger.
"Well, what do you think?"
"It's…weird." Ami said, looking disgusted. "I don't like it." She looked around at them, looking at Komaru and Makoto. "What are you doing?"
"Oh, just another one of the many games siblings can play together when you love each other so much. Speaking of which, if Rantaro is okay with it, Komaru and I can show you some of them more personally~"
"It's…fine. I need a few minutes to recover." Rantaro said.
Komaru looked unsure, expecting that Makoto was wanting her to actually join in, and expecting to be sidelined if she did.
"Okay! I like playing games!" She said with a smile. "Can I…wipe this off first, though?"
Makoto watched Ami's little butt bounce as she skipped off to the bathroom, before turning back to Komaru. "What position do you think she'd like the most?"
"What?" Komaru asked.
"For having sex? What looks the best?"
Komaru suddenly became angry as she misunderstood. "Oh, so now you're gonna fuck her too?!"
"No, to watch. That's why I said 'look.'"
Komaru took a moment to process this, and then frowned again. "Ohhhhh, I see…you're gonna fuck Rantaro!"
"What, no? I'm not gay. No offense, Rantaro."
"None taken." The boy said.
"Yuta." Komaru said simply.
"That was one time! One time!"
"A time you seemed to really enjoy." Komaru said.
"I mean…it felt a lot less different from being with a girl than I thought it would."
"Admit it. At the very least, you're bi."
"We're not having this argument, back on topic, what do you think she'd find hottest for us to do?"
Komaru opened her mouth, and then paused as his words sank in. "Oh…you meant us?"
"...YES!" Makoto exclaimed.
Komaru laughed nervously. "Right…sorry!"
"Now, since you can't answer, Rantaro, what would look best?"
"Something gentle, romantic even. I want Ami to have good exposure." Rentaro said.
"For that, I think the best if for you to sit down, and I ride on top of you, yeah?" Komaru offered.
"Sure! Plus if she wants to try it out, that's probably the safest position for her." Makoto agreed.
"It took a bit of effort, but I got it!" Ami exclaimed as she returned, a smile on her face still.
"You look so pretty!" Makoto said, and Komaru pinched Makoto's butt. "Yeep!" Makoto squeaked before scowling at Komaru, then turning back to Ami with a smile. "Now, are you ready to see something really fun siblings can do with each other?"
"Yeah!" Ami said.
"Before we get into it, so Ami doesn't get too pent up, Komaru, do you want to show her how to masturbate?" Makoto asked.
Komaru grabbed Makoto's body, and threw him against the chair as she quickly crawled on top of him. "That can wait, it's my turn, alright~" Komaru said with a hint of venom both in her voice and in her smile. Makoto was shocked by Komaru's response, but from the way his cock twitched a little as the words left her mouth, he wasn't altogether opposed.
"Watch carefully Ami. This is something very special you can do for your brother." Komaru said as she lifted herself up, and put Makoto's dick just against her folds, before she began to lower herself down, gasping as it entered her. Ami watched in awe as Komaru pushed herself down, experiencing brief flashes of pain as she moved further and further down, until his dick was entirely enveloped by her pussy.
Makoto moaned loudly, reaching around to grope Komaru's ass. "G-god..." he couldn't resist muttering.
As Komaru lifted herself up and slammed her body back down on the boy's dick, she leaned forward and whispered in his ear. "B-boobs…"
Her brother quickly complied, moving his hands back and up to her chest, groping her forcefully while at the same time thrusting his hips in time with her; pulling out as she raised herself and thrusting as she went down. "B-both partners should be active-" Makoto tried lecturing to Ami.
Komaru silenced him with a deep, passionate kiss, moaning into his mouth, which made Ami gaze at them with wonder. Makoto's eyes closed as he pushed his tongue into Komaru's mouth, pinching both of her nipples and pulling on them as well. The girl wrestled her own tongue against her brother's as she moved up and down on his dick, moaning loudly as she let out all her pent up frustration.
"Are you enjoying, Ami?" Rantaro asked.
"Yes! I wanna do it with you!" Ami said.
Komaru was the first to come, and she groaned as her juices exploded out of her, coating the boy's dick and pelvis with her fluids as her entire body shuddered wildly. Makoto pulled away from her breasts and wrapped Komaru into a hug as he came as well, pumping her full of his cum as they both held onto each other as tight as possible.
"F-fuuuuck…" She groaned, panting and heaving, her breasts moving up and down with her breathing.
Makoto looked up and smiled at her. "Feel better?"
"Y-yes…" Komaru breathed.
"Wowww! You both looked like you really liked it! I wanna do that!" Ami said. Without warning, she ran over, jumped onto Rantaro's lap, and grabbed his penis, shoving it only an inch inside her before she suddenly screamed in pain.
"Geez!" Rantaro yelped as he grabbed her hips and held her up. "You have to take it slow! Komaru is way more experienced than you!"
"O-owwww…" Ami said, tears welling up in her eyes.
Makoto rushed over and lifted her off of Rantaro's lap. "Are you okay?"
"I-is it supposed to h-hurt?" She asked.
"No, but that's what happens if you do it too fast, especially if it's your first time." Makoto explained.
"S-so…it'll…feel better if I take it slow?"
Rantaro smiled as he got on one knee next to her. "Of course, I'll make sure you love it~"
"Okay…" She said, and raised her arms to be picked back up to get back on his lap.
Rantaro picked her up and, for fun, lifted her above his head and bounced her a bit. "Remember when we used to do this all the time?"
Makoto sat down next to Komaru and whispered in her ear. "Does the 'cutesiness' make it worse or better?"
"I'm not the pedophile here, you are." Komaru said with a smirk.
"Yeah!" Ami said, already feeling better.
Rantaro sat down in the chair and rested Ami on his lap, his cock poking against her stomach. "Ready?"
"That's not fair, you were the one burying Monaca's face with your tits." Makoto said.
"…Fair point." Komaru conceded, and watched Ami and Rantaro, seeing Ami nod to his question.
Gently, Rantaro lifted her to her knees and positioned his cock against her pussy. It looked so monstrous next to her, the head alone almost being bigger than her labia, and yet, the sight of it made Ami's older brother twitch a bit. "You're sure you're sure?" Ami responded by lowering her own body down, gently inserting part of the head inside her. She gasped as the pain came rushing back, though not as intensely this time. Rantaro held her in place, gently bouncing her and thrusting mere centimeters in and out of her.
"Y'know, I don't remember the first time we had sex that well," Makoto reminisced.
"Me neither. Though I do know you started it, perv." Komaru said.
"Ahhh…ahhhhhhh…" Ami groaned, the pain slowly beginning to fade as an intense feeling she'd never experienced before shot through her body.
"Do you want me to go deeper~?" Rantaro encouraged.
"Not like you didn't like it," Makoto shot back.
"Yeah, yeah." Komaru said, grabbing his hand wrapped hers around it.
"Y-yes please." Ami answered softly.
Makoto pressed a kiss against Komaru's head as Rantaro eased Ami a bit further down his cock, getting it halfway inside of her.
"I-it…it's so…b-big…" Ami groaned, her entire body shaking.
Rantaro blushed a bit. "If it's too much we can stop-"
"N-no! I want you…to feel good…"
Rantaro let out an audible moan. "Ami, I love you! So much!"
"Were we ever this sappy?" Makoto inquired.
"Nah, but that's fine." She looked over at them, and sighed as she looked down at her and Makoto's clasped hands. "If you…want to join in…"
"Join?"
Meanwhile, Rantaro finally managed to get his entire cock into Ami, the outline of it almost painfully visible against her petite body. "You did it Ami, amazing job!"
"D-do you…feel good?" Ami asked between breaths, her body still shaking.
"If Rantaro will let you…you can join in. Maybe grope her and stuff." Komaru explained.
"Oh!" Makoto exclaimed. "I thought you wanted me to fuck her butt."
"I feel amazing, Ami~" Rantaro cooed before leaning forward to kiss one of her nipples.
"Nah, I don't think she's ready for that." Komaru said. "But yeah, only if you want to."
Ami could feel the pleasure starting to rush through her, as well as a strange pressure in what felt like her belly. Rantaro started bouncing her more vigorously, lifting her up an inch or two on his cock before forcing her back down, each pump eliciting a series of loud moans and cries from her in addition to the smacking of her petite body against his.
Makoto, meanwhile, leaned over to Komaru and put his hand between her legs. "I think you need a bit more attention, you seemed really frustrated earlier."
"Nnnng…" Komaru groaned. "P-please…" She begged softly.
Makoto grinned as he started fingering his sister. "You're really easy to please, y'know that~?"
At the same time Makoto started gently, Rantaro began picking up the pace; slamming several inches in and out of Ami with every thrust and making her entire body shudder every time he did.
"Ahhhhh!" Ami exclaimed. The pain had almost faded completely by this point, and she felt that pressure building up more and more as her body moved up and down. Her body seemed to grasp his dick so tightly.
"Sh-shut up…" Komaru gasped, his fingers feeling so good against her wet pussy.
"Kiss me~" Rantaro implored his sister as Makoto bit down on Komaru's neck, gently. Ami immediately did as he asked, pressing her lips against his, feeling just how soft his were.
"G-god damn it…" Komaru groaned.
Rantaro's thrusts grew shorter and quicker as one hand reached around to grope Ami's ass.
"Feeling close~?" Makoto and Rantaro whispered at the same time.
"Just…a bit more…" Komaru said, while Ami just gave Rantaro a confused look.
"You'll know when it happens," Rantaro reassured his sister as he used his other hand to start massaging her clit.
All Ami knew was that feeling inside her was becoming unbearable, and it felt similar to when she needed to pee, yet unlike that, it felt absolutely incredible as it continued to build and build.
Rantaro slammed her down on his cock and released, flooding his underage sister's virgin womb with cum as his entire body jerked and shuddered against her.
While he was in the middle of cumming, the feeling of his warm fluid filling her was enough to tip her over the edge, and she cried out as she too came, not that she was aware of what she was doing. At the same time, Komaru also came, spraying onto Makoto's hand and the floor as her body twitched and her toes curled, both girls' moans filling the air as they unloaded everything they had, until they were left panting, Ami slumped over Rantaro while Komaru laid back against her chair.
"So, how does everyone feel?" Makoto chirped, on account of being the only person there who hadn't just came.
"Ahhhh…"
"Uggggghhhhh…"
"Jesus..."
Makoto leapt off the floor and started getting dressed. "Fun evening, but I think Rantaro and Ami need to be heading home. Komaru, would you mind accompanying them?"
"S-sure…" Komaru said as she stood up on shaky legs, and then walked over to Makoto, leaning on him for support, leaning in to whisper in his ear. "I'm gonna give you such a damn good blow later…" She promised as Ami crawled off of Rantaro's lap.
Makoto shuddered a bit, but her sudden praise couldn't override his big brother instincts as he picked up her clothes and underwear.
"Did you have fun, Ami?" Rantaro asked.
"Yeah!" She said with enthusiasm, grabbing his arm and holding onto it tightly. "I…wanna do more adult stuff with you at home."
"Looks like it worked." Komaru said, and then gave Makoto a confused look when she saw him carrying her clothes. "What are you doing?"
Makoto whistled as he walked past Komaru and dropped her clothes in the hamper.
"Well, we'll have to plan around everyone else…AH! Speaking of which, no one else can ever know about this! Makoto and Komaru are the only other people you can talk about this stuff to."
"Oh, okay!" She said, not really getting it, but agreeing.
"Are you really gonna make me walk them back naked? I'd rather not get arrested, thank you very much." Komaru said, putting her hands on her hips as she looked at Makoto.
Makoto stuck his tongue out, then fished out her panties.
Komaru raised an eyebrow as she stared at him.
And watched as he then put them over her head.
"What…the hell are you doing?" She asked.
"This is the only article of clothing you're allowed to wear."
"No." Komaru said simply, giving him a look that says this wasn't up for debate. "There's a difference between exhibitionism and straight up being stupid, you know."
Makoto groaned. "You're no fun, but fine..."
As an attempt at compromise, he pulled out her shirt and panties.
Sighing, Komaru snatched them, and slipped them on, but kept the panties on her head as well. Her nipples poked out against the fabric of the shirt as she stood there in just the shirt and the panties, turning to the other two, who were now also dressed. "Alright, let's go." She heard Ami giggle, but just rolled her eyes as she led them out the door, giving Makoto one last glare before leaving.
