A Sloppy Froppy

Tsuyu Asui left the hero dormitories early one afternoon, promising she would be back soon with the aforementioned groceries for cooking and baking that week. As she entered the store a while later she double checked the store to be sure no one, save the security cameras would take notice of her suspicious activity. Tsuyu began to walk towards the incontinence and medical needs aisle, looking for a particular package on the shelves within. Upon eyeing the package, a curled grin came up over tsuyus face as she grabbed the large plastic packaging. Quickly stuffing the package into a hand basket, she continued on, towards the groceries and the baking ingredients her friends requested. After placing everything in the basket Tsuyu began to approach the counter, pretending her purchases were completely normal and everything was commonplace. The cashier simply took the items out of the basket, scanned them, making Tsuyu nearly visibly groan when the plastic package of adult diapers were scanned. Finally, the cash was exchanged and Tsuyu bid the cashier thanks and scurried out of the store, making sure to cover her package with another bag to prevent anyone knowing the contents. As she scanned her ID and entered back into the dormitory area, Tsuyu was greeted by Ochako Uraraka, her classmate and the one who had sent her to get the groceries. Tsuyu bid her hello, handing the bags of groceries and cooking ingredients to Ochako and beginning to walk away. Ochako eyed the other covered plastic package Tsuyu had and asked her, causing Tsuyu to nervously but calmly state, this was a gift for someone and wanted to keep it under wraps. Ochako just smiled and nodded, and went into the dorms, Tsuyu following behind but immediately heading for her dorm room, closing the door and nervously breathing and listening to the outside walls. She was alone now, and she knew it was just a couple of her classmates in the dorm, Iida, Ochako, Mina, and Todoroki at this time of day, so she would be left alone for a few hours if no one came to ask her about dinner. Tsuyu simply smiled and locked her door, and grabbed a couple of soundproofing foam pads to pad up near her door. Alone and quiet, she figured. Tsuyu nervously grabbed the package out of the plastic bags, the label reading Extra Absorbent Night Time Incontinence Briefs. However, Tsuyu had surmised, these were far more than briefs, these were diapers, and she had pondered and fascinated over how they would feel to be worn. A devilish grin and a low "Kero" were said as Tsuyu slipped her panties off around her legs and threw them into her laundry basket. She tore open the plastic packaging and grabbed one of the diapers, feeling the texture and feeling the desire to finally experience this strange idea she had been desiring. Tsuyu pulled the diaper open, and observed how to properly tape one onto her body, as well as her picking an adult diaper that fit snugly around her frame. As she lay on her bed, Tsuyu remembered a vital part of being diapered, as she had younger siblings she took care of, was to apply powder and lotion before putting on a diaper, and so Tsuyu pulled open a drawer of lotions and oils, and pulled out a bottle of baby powder and baby lotion. She squirted some of the lotion on her hands and actively began massaging her groin and her anal areas. After acknowledging her accomplishment, and feeling a bit of pleasure from the experience, Tsuyu began to powder herself. The lotion and powder on, Tsuyu pulled the front tapes of the diaper up over her groin, and taped the 3 tapes on each side snugly to her waist. She hopped up off the bed, dusting off residual powder and examined her waistline in the mirror. For her first adult diaper, Tsuyu thought she did an excellent job and the tapes were snug around her sides. After a bit of cleanup, Tsuyu began to experiment rubbing the front of her diaper, the plastic front, calming and smooth pushing against her clitoris gave her chills. She then realized she needed to use the bathroom, and Tsuyu smiled and looked down patting the front of her diaper as she let herself pee into it, the stream swelling up the front and bottom of her diaper well and the warmth plastic swelling under her hand, she moaned softly with a faint keroooo as this process ended, and knowing she had just wet herself, in a diaper, for the first time. Tsuyu felt incredibly naughty, and wondered how much more she could push this diaper out. Push. She then stood up, squatting down and feeling her abdomen tighten up, as Tsuyu pushed and allowed the warm, mushy substance fill up her backside, immense waves of relief and pleasure surged through her, nearly sweating and tongue hanging out of her mouth. Tsuyu, crouching, remembered what her younger siblings did and sat in their own mush, waiting for a change, and Tsuyu would oblige that notion, as she fell onto her bottom, the warm mess mashing itself along her ass and spreading it's warmth through her diaper. The surge of pleasure was unbelievable to Tsuyu, and she lay back and began to frivolously rub the front of her loaded diaper, feeling the urge to cum with each buck and surge. Finally, she released into her warm diaper and Tsuyu laid back, comfortable, tired, sweaty, and ready to rest. Hours passed and her sleep was abruptly awoken as her door was opened up, by Ochako. The expression on Tsuyus face was one of terror, surprise, and incredible confusion. "A gift huh, for yourself." Ochako merely smiled, and produced a pacifier from behind her back, popping it into Tsuyus mouth. "You think you're the only one who wants to pamper themselves every once in a while?" Ochako smiled and pulled the top portion of her sweatpants down, revealing to Tsuyu a decently soaked adult diaper with pink faded circle patterns. Tsuyu started crying and Ochako, closing the door behind her, came to the crying frog girls aid. She tenderly pulled another diaper out of the package and lay it beside Tsuyu, now sucking slowly on the pacifier with tear streaked face. Ochako pulled open Tsuyus cabinet, looking for a package of wet wipes, and produced several wipes to clean up the dirty baby girl. After a few minutes and a balled up diaper, Tsuyu sat up, a new diaper around her waist, and hugged and kissed Ochako on the cheek. "A secret between girl heroes, we've got to keep our weaknesses under wraps, right?" Ochako smiled. Tsuyu then pulled a pair of pajama pants out of her closet and pulled them over her fresh diaper, looking back at Ochako and noting what to do with the messy diaper. "Don't worry, Asui. The bin chute is right down the hall, the other girls won't notice." She smirked and walked out, back down to the kitchen to have dinner with her friends, and Tsuyu, noting her new-found best friend, tossed the diaper into the trash and no one was any the wiser. The coming weeks Uravity and Froppy the hero spend a lot of time together after classes, always looking more reserved and bubbly, and even Deku was curious. However that is for another story...
