Alright, since enough people asked, here you go!

Piper's heart beat inside her chest at this predicament she suddenly found herself in. The wet wipes that had Annabeth had put inside of her Underjam had warmed during the car ride from the mall back to Piper's Malibu house, but now the wipes suddenly felt just as cold as when Annabeth put them there.
Piper had told Jason before about her secret kink, and he had made it clear that he wasn't going to be wearing any diapers/pull-ups, using any diapers/pull-ups, and he was not going to be changing any diapers or pull-ups, but he also hadn't told Piper she was a freak or a deviant or a pervert or anything like that, so it kind of evened out. Because of that sentiment, Piper was in a little bit of shock right now.
Piper looked at Annabeth for an explanation as to what was happening, but all she saw were crossed arms and a stern look, not unlike a mother who was disappointed and angry at her toddler for peeing and pooping their pants when they knew to ask for the potty. However, Piper, did see the amusement glittering in Annabeth's eyes.
The daughter of Aphrodite looked back at her boyfriend, this time with a clearer mind, and saw that his eyes were likewise glittering. Actually, Jason looked like he was trying to keep it together, with the corners of his mouth trembling as he tried not to smile.
They were still roleplaying, Piper realized. Annabeth was still being her Mommy and now Jason was her Daddy—which made Piper wonder about her state of mental health and whether this was a betrayal of Percy on Annabeth's part. You know, Piper had a dad, one she loved very much and who loved her very much back; what sense did it make to refer to Jason as her Daddy, even if it was just for roleplaying? As for Annabeth, if she was Piper's Mommy, typically a role assumed by a dominant lesbian, did that mean that in some way, she was cheating on Percy?
Piper decided that these questions were too complicated to waste energy on trying to answer. Right now wasn't the time to figure out the rightness or wrongness of the situation—right now was about having fun and letting go of the stresses of high school and the demigod life!
Piper shifted on the balls of her feet. "I'm sorry, Daddy…"
"Sorry does not cut it, young lady," Jason said sternly. "You are four years old and will be starting kindergarten in the Fall, and the school has already told me that they do not accept little girls who still tinkle and go poo-poo in pull-ups. Just yesterday you peed in three of your Underjams, and pooped in two of those, and only used the potty once because I made you sit on it for thirty minutes. Today, your mother has told me you've had three tinkle accidents again, another poopy one, and that you used one of your Underjams as a substitute for toilet paper and it had a big poop stain in it. That is unacceptable."
Jason let out a mock sigh. "What are we going to do with you, Piper Grace McLean?"
Piper didn't know, but all that talk about pooping her pants was kind of ironic. Besides her potty-training days, Piper had only pooped her pants twice: the first time was to get back at Jane, her dad's mean secretary, and she left her messy Underjam in the woman's office in a place that was never found, letting it stink up the whole place for days on end, and the second time Piper pooped herself was because of Drew Tanaka, the former councilor of the Aphrodite Cabin and Piper's half-sister.
It was back during the construction of the Argo II. Drew used her charmspeak on the nymphs and satyrs to spike Piper's food with stuff that left her constipated for three days, and then on the fourth day had the nature spirits spike Piper's food with powerful laxatives and stool softeners. Piper had been in the middle of talking with Annabeth in Bunker Nine when the cramps hit her like a freight train. She was able to hobble about five steps towards the toilet when another cramp hit her, and her bowels gave way right there in front of the blonde.
Piper sobbed in Annabeth's arms for almost an hour, her shorts and panties ruined, her personal atmosphere foul and putrid.
What added insult to injury was when Leo had come back from whatever he had been doing, sniffed the air, recoiled, and then made a fart joke at the girls' expenses, making Piper cry even harder. Leo was of course filled with the utmost regret when Annabeth told him what the source of the smell was.
After they got Piper calmed down and functional again, Annabeth helped her get cleaned up and deduced that it was Drew who had done this to Piper in an attempt to take back control of the cabin by making Piper look inept and stupid. After all, who would want to follow a cabin leader who pooped her pants like a baby?
Anyway, the girls got back at Drew with Leo's help. The son of Hephaestus rigged the Aphrodite cabin's toilet while Piper and Annabeth pulled a similar chemical trick on Drew that she pulled on Piper. Through the laxatives, Drew had needed the toilet, and through Leo, after Drew had finished expelling all of her waste, the toilet water all yellow, and her loose, watery poop all floating on the surface of the water like moss, and before she could even reach for the toilet paper to start wiping, mechanical arms had come out of the toilet, lifting Drew up and dunking her headfirst into the toilet filled with her own filth.
The arms had dunked her up and down like a toilet plunger at first, then held her under for a few seconds before flushing, giving her one of the nastiest swirlies in all of history, and then the arms dragged her head around the bowl like a toilet brush, using her hair to clean off the remaining stains from the porcelain before flushing one more time.
Adding insult to injury to all this was that while she was being subjected to her chocolate swirly, another set of arms had a hold of her pink lace tanga panties and were alternating in dragging the fabric back and forth through her nethers like a saw; a squeaky clean wedgie, as it was, but it was a squeaky clean wedgie with her nethers having yet to be cleaned from the most recent round of pee and poop that just came out of her, and so her panties were getting used as toilet paper.
Literally squeaky clean.
After the final flush came the final insult. The arms pulled Drew out of the toilet, sopping wet and trembling, ripped her shorts off, and then put an outrageously thick cloth diaper on over her stretched underwear, followed by a pair extra crinkly pink plastic panties with designs all over it of baby items, like rattles, bottles, pacifiers, stuffed animals, etc. The arms finished Drew's new look with an over-the-top baby bonnet with a big, wide, lacy, frilly pink and white brim, and an oversized pacifier was shoved into Drew's mouth and then secured around her head with ribbons, the nipple having been previously dipped in lye soap, making the teenager's mouth burn.
That's when Piper had stepped into the bathroom, waving her hand in front of her nose. "Pee-yew! What a stinky baby!"
Drew was totally mortified, staring at Piper with wide eyes, her whole body shaking like a leaf.
"Yeah, I know it was you that spiked my meals, and congratulations, you did get me to poop myself. Consider this to be simple retaliation. I've got the whole thing on video, so if you ever think about usurping me again, especially in the way you tried, this video doesn't just go viral…your new look becomes permanent, you little cutie pie."
Piper winked and left Drew alone with the residual smell of her filth, leaving her by herself to figure out where to go from here.
The Hero of Olympus was broken out of her reverie when she felt the side of her Underjam come undone, the flimsy material ripping apart because it was unable to handle the tension of her teenage body and all the wipes weighing down the seat.
"I don't know…" Piper said quietly in response to Jason's question, just like a petulant child.
Initially shocked to actually find this happening to her, Piper got right back into the swing of things.
"I suppose the first thing we can do is make sure we don't have to worry about any Underjams for a while, since you don't seem to want to use the potty like a big girl anyway."
Piper's heart skipped a beat when Jason said that, the implications making her excited and not a small amount of hot under her collar.
Jason walked over, grabbed her hand, and lead her through the house to her bedroom. He shut the door behind them, and what Piper saw on her bed made her heart really start to beat, and made her lopsided Underjam start to feel moist and damp between her legs.
Without asking for any kind of permission or giving out any instructions, Jason yanked Piper's skirt down to her ankles, snorted at the bulging, stressed-out Underjam that was about to come apart at the other side and just completely fall off Piper's body, and finished the process by tearing the bedwetting diaper off, leaving Piper naked except for her Hello Kitty tee and her socks and shoes.
Jason had never been this dominant or assertive before, and Piper could honestly say she was really enjoying it, being handled like naughty little girl by her cross Daddy.
Hm, maybe she had Daddy Issues after all.
Jason grabbed Piper's hand again and marched her to the bed, pushing her onto it. Piper thought he just gonna take that big pink diaper and put it on her, but instead her pushed her legs apart and licked at her privates, making her let out a surprised squeak in conjunction with a lewd moan as her hot girlhood received attention from the son of the sky god, who might as well have been the god of sex with how much he got around.
Piper was on Cloud Nine. She and Jason had only been on second base before today, and today was only supposed to entail engaging in a bit roleplay at the mall with Annabeth, and now here she was, finally getting her pussy eaten with a big, thick diaper awaiting her. Sure, Underjams were Piper's all-time favorites, but she did appreciate a comfy diaper.
Jason licked and licked, using his thumb to stimulate Piper's clit, swirling his tongue in a way that Piper was sure was the alphabet, and before long, not even a full four minutes into it, Piper's virgin body reached climax. She felt her muscles clamp around Jason's tongue as her cum went gushing from her. Thick, milky, and tasting of sugar, Jason lapped it all up, panting.
"Well…won't have to worry about you making any big girl messes for a while."
"Gods, Jason," Piper gasped, her body still rocking with pleasure. "That was amazing."
"We're done yet," Jason smirked, his lips still glistening with Piper's fluids.
He picked up the pink diaper, plastic-backed and super loud and crinkly, unfolded it, and with Piper's compliance, got it under her and into place. That's when he held up a pink object that looked like it had a button on the bottom of it. Piper realized what that was and she felt her asshole quiver.
"Want to?" Jason asked.
Piper eagerly nodded, and so Jason easily slipped the vibrating buttplug into place, Piper gasping as her anal muscles were gently pushed apart by the toy and then held like that due to the silicon. Jason applied a generous amount of baby lotion and baby powder, making Piper jump and flinch due to how sensitive she still was. Jason brought the front of Piper's diaper up and taped it snuggly in place.
"There, no more potty for you for a while. Not that you were using it in the first place."
Jason picked Piper up and settled her on his hip, making her wince and gasp because his arm was supporting her weight by sitting under her butt, driving the plug in a little deeper. Jason carried Piper back to the living room, where Piper discovered that Annabeth had set up a playpen, put some baby toys therein, and had the house's 100-inch flatscreen will full surround sound on and set to PBS, just in time to catch Sesame Street.
"Aw, what a cutie!" Annabeth exclaimed at seeing Piper in her t-shirt, diaper, and shoes.
Annabeth came over and pinched Piper's cheek. "Who's a cute baby, huh? You are! Yes, you are!"
Piper flushed.
Jason set her down in the playpen, and Annabeth handed Piper a pink sippy cup that had a wrap-around portrait of the main Disney Princesses on it.
"You be a good girl," Jason commanded. "Your Mommy and I need to go pay bills, so when you need your diaper changed, scream like a baby."
Piper gave a thumbs-up, and the two adult demigods left the living room. Piper had a passing worry that "pay bills" translated to "have sex," but she shook her head. Annabeth was too loyal to Percy and Jason wouldn't do that anyway. Piper considered it a monumental achievement on Jason's part that he took the initiative to eat her out without her having to ask or drop hints or just be naked in the bedroom for him.
Piper took a few sips from her sippy, finding the chocolate milk to be absolutely exquisite, making her wonder what Annabeth had done to make it taste so wonderful, when the plug inside her ass suddenly went off, vibrating like mad. Piper moaned and flopped over, driving her hand into her diaper to rub at the vibrating plug. She hadn't known it was remote operated!
Then it stopped.
Piper let out a pitiful whine and pouted, figuring that this was the new game. Jason was going to keep activating the plug at random times, driving Piper into a pleasurable haze of ecstasy, and then he was going to rip her out of it by hitting the off button. Piper huffed and grunted at this new arrangement, and let out a sizeable stream of pee into her diaper.
Nowhere near enough for a change for a diaper this thick and thirsty, but it certainly would've been enough for the capacity of a simple Underjam.
For as long as the Sesame Street episode went on, Piper would drink from her sippy cup, moan when her plug turned on, and then whine when it went off. Each time it did come on though, Piper could feel herself getting closer and closer to another orgasm.
Hm, orgasming due to a vibrating buttplug…did that make her a slut? Cumming from anal? Piper didn't know, and she decided not to worry about thinking about.
After another episode of Sesame Street, Piper's diaper was still only halfway filled to capacity with tinkle, and she was almost there. Probably just one more round of vibrating would be enough for Piper. Her sippy was empty, and she had played with all the toys during the commercial breaks. Her ADHD was starting to catch up with her, and she was beginning to find herself getting antsy and anxious being stuck in this playpen.
It wasn't like she couldn't get out, as this was only a baby-sized pen, but still. Piper had a feeling she wasn't supposed to get out. She was supposed to be a naughty girl right now, in trouble for going potty in her Underjams and not in the potty….Hang on.
She was supposed to be a naughty girl right now. Naughty girls didn't do what they were told. Besides, her stomach was starting to feel the telltale pressure of an impending bowel movement, something she couldn't perform due to her ass being plugged at the moment, and Piper didn't really fancy the idea of pooping in her diaper. She had to be in the right kind of mood to consider making a mess of her pants, and right now she was not in that mood.
Piper crawled out of her playpen to go sneak to the bathroom to take her diaper off and her plug out, when Jason came thundering around the corner.
"Piper Grace McLean!" came the booming voice of angry Daddy Jason, making Piper flinch so bad she stumbled and fell to her butt, making her squeak and her bladder release once more.
Jason grabbed Piper by the arm, hoisted her up, and brought her over to the couch, throwing her over his knee. Piper yelped when Jason's powerful hand came on the back of her thigh, a place unprotected by the thick padding of her pink, swollen, discolored diaper.
"You—do—not—get—out—of—your—play—pen—with—out—mine—or—Mommy's—permission, young lady!" Jason said, punctuating each word with a powerful spank, leaving Piper's legs blistered and stinging since Jason could really pack a wallop when he wanted. "Do you understand me!?"
Just to make matters worse, it was revealed to Piper that Annabeth was the one with the remote to the buttplug, and the blonde had turned it on just a little after Piper's spanking began, and so the daughter of Aphrodite was left a blubbering, incoherent mess from the vibrations of the plug and from Jason's spanking.
Piper tried to say "Yes, Daddy," but all that came out of her mouth was "Guh-guh-duh-blugh," because Annabeth hit a button and Piper's plug went off at its highest frequency, driving the usually dignified daughter of Aphrodite into a state comparable to that of a sex-crazed whore.
Piper's face screwed up and her tongue fell out of her mouth in the perfect ahegao face as the pleasure of orgasm ripped through her. She collapsed over Jason's lap, her diaper soaked with piss and cum, and the only keeping it from being totally filled to the brim was the buttplug that Annabeth had benevolently shut off when she saw Piper cum.
"Time for this one to go nap-nap," Piper heard someone say from Io, the largest moon of Jupiter.
She was vaguely aware of being picked up and carried, then set down on her bed and under the covers. She barely registered the stretch of her ass vanishing, and the pressure in her tummy disappearing in tandem with the feeling of something warm and lumpy sliding into the seat of her diaper, making it expand and grow just a little tighter around her hips.
Piper's last conscious thought before she fell asleep was that of a nasty smell wafting into her nose.

Piper would be woken up a little over an hour later, and by that time the poop in her diaper had become solid and stuck to her. It was also by that time that playtime was over for the day, and so after Piper showered and her filthy diaper disposed of, she put on a pair of big girl undies and greeted her father when he came home a little bit later from a day on set.
Jason and Annabeth bid Piper their goodbyes, and all three of them were left eagerly anticipating the next time they could get together and play.

That's it for this story.
I think I'll pick up work on the Artemis Punishment next.
