Chapter 1 - I Only Wish The Good Times Would Last A Little Longer
Kyoka was already wearing nothing but her uniform skirt as she sat around the dorm lounge in the first place. Just a coincidence, idly sucking on Koji's cock while she listened to some new tunes, nothing major. It was just how she felt comfortable and ready to hang out. Nobody lasted more than a month at U.A. without having their standards and boundaries eroded a little bit. Between the nudity, the casual free use sex in the dorms at all hours, the way that every part of the school except for classrooms was just a low-key fuckfest at all times, even people who didn't get too involved became numb to it, and by year's end nobody was really above getting down and dirty wherever they pleased.
But when All Might arrived at the dorm lounge to say proudly, "It is the birthday of one lucky girl, and I am here to pay her a visit," suddenly being in nothing but her skirt was a good thing. She looked up in surprise, having already paused her music and pulled away from Koji's lap with his cum dripping from her mouth. Her eyes widened. "Miss Jiro."
Everyone looked at Kyoka with delight. As much as people had grown numb to all the sex happening at all hours, there was something to be said for the appeal of seeing All Might visit the dorms. He was usually too busy to fuck students the way other teachers did, and more excitingly, his visits to the dorms on girls' birthdays to fuck them in front of everyone and then lead a train of all the boys onto her pussy was something that everyone was happy to get all kinds of worked up for. Only days earlier, he'd done the same with Mina, and with fond memories of the hours-long fuckfest that ensued fresh in everyone's minds, his arrival now to fuck Kyoka had people excited.
Sure, in any given day, Kyoka had most of her class using her holes. But how often did they get to fuck her in a sloppy seconds orgy overseen by the number one pro hero in Japan?
"Yes, it's my birthday," she said, unable to keep from cracking a smile as she drew toward him. All Might took his seat on a nearby couch, right in the middle of the room, the center of all attention. She followed, standing by him with a smile as he got one of his big hands around her waist, slipping it up her skirt and jamming a finger into her pussy as his other reached into his lap, getting his pants out of the way and seeking to indulge in her body. "And I can't think of any better way to celebrate than getting my brains fucked out by you."
All Might's smile was big and it was greedy. He was happy to see Kyoka all worked up and needy for him as he pulled out his thick, waiting cock, guiding her into his lap, lifting up her skirt and getting her primed for his touch, greedily seizing hold of her and starting in hard on the pleasure that awaited him. His grip on her tightened as he tugged her onto his cock, impaling her down with a firm, swift motion, her legs settling against the ground and against his hands as she pushed her butt down hard against his lap and met the commotion eagerly. There was no restraint. No sense. No time to hold back. Just pleasure.
The feeling of All Might's big cock sinking into her ready hole was an absolute delight for Kyoka. Vocal and wild, she found herself hit by pleasures that she couldn't have been happier to meet, all eyes on her now as he filled her, and her hips didn't need guidance to begin their feverish descent. With greedy motions up and down, Kyoka began in earnest, heaving up and down his cock with rocky, frantic gestures of wild lust. "Mina's been moaning about how big you are for days, and now I feel why!" she gasped out, proudly proclaiming with delight and shaky lust for everyone to hear. Her body was ready now, given to raw desires and to the idea of letting go completely.
"You're tighter than she is," All Might groaned. Going from the thicker moth girl and her wide hips to this slender punk rocker was a joy, his body tightening up as he held strong and prepared himself for the wild commotion that followed, pleasures high and wicked. He didn't shy away from any of what began to take him, his body lit up with wanton delight and a pleasure too strong to hold back. It was just pleasure. Just feverish, focused delight. He didn't need to do much, but he was happy to guide her in her wild motions along his shaft.
Kyoka's skirt did a bit to obscure the penetration, but there was nothing decent or sweet about the fiery and reckless bliss that took them all by storm now. Her moans and the heaving of her otherwise naked body as she took on this pleasure and fucked herself down with greed and joy onto his meaty cock were all so blatant and so reckless that nothing about this was even remotely normal. The senseless pleasures were there for everyone to see. Mina had dealt with All Might naked, but the tasteful obscuring of her pussy only added a sweet sort of thrill to the whole situation, a depraved mystery that still did little to leave anyone doubting that they knew precisely what was going on underneath that skirt.
Her face twisted in all manner of aimless pleasure, showing off just how helpless and shaky Kyoka was, how much the big cock thrilling her took a toll on her, and in turn it became all the simpler for her to completely melt under this mess, struggling to find some semblance of reason and control as she kept riding harder. She was fitful and shameless, giving in to every feral pulse of desire and hunger all at once, not caring how aimless and frazzled she felt, not for a moment concerned with what she was doing, but caring only about letting herself go.
"And to think, after I'm done fucking you, all these boys are going to use your body, too." All Might gave her ass a smack through her skirt, making her shriek and heave as she kept racing through all this senseless delight. It was overwhelming in the best of ways, Kyoka happily inching closer toward indecent, unraveling ruin as she took the meaty cock, as her normal slutty indulgences spiraled into something even more over the top through the satisfaction of letting herself succumb. She wasn't subtle or chaste or restrained in any of this, falling deeper into the raw confusion and desire that felt too shameful and too dizzy to believe.
As her riding drew more intense, Kyoka spread her legs out. Her skirt rose up, exposing the sight of the huge cock pounding her tight teen hole, eyes shaky as she pushed on faster and needier, unable to resist the crushing desires continuing to take her by storm, and she was unable to resist all these needs. The pleasure was getting to be too much, and there felt like nothing she could want more than to let it rule her. Feverish motions back and forth kept up, driving her hard over the edge and demanding that she succumb fully.
But before she could cum, All Might did. He groaned, holding her down by the hips onto his cock and pumping her full of a hot, gooey mess. "I am here!" he screamed as he came, because All Might sincerely did repeat his catchphrase while creampieing students. Nobody was sure if it was a joke or not, but as he filled her with his cum, Kyoka didn't really care. Shaky, thrashing, shit her own orgasm, spine arching back and her surrender coming on with maddened desire. But in that moment, something else happened that she was in no way ready for.
Cumming really hard had a tendency to make Kyoka lose control of her bladder. She wasn't ashamed of it. Enough perversion happened around U.A. that watersports had become an almost normal, commonplace kind of kink. But still, she didn't exactly mean to start pissing on the floor while she came from getting creamed by the top hero in the country, and as she whined and emptied her bladder on the floor in confusion, she found herself leaning back against him, struggling to save face by moaning, "Pee in me," and hoping she could find some way to redeem this mess.
And All Might did. With his cock buried inside of the teenager, he too let go of his bladder and began to flush out the pussy he just fucked with his own hot piss, a sensation that made Kyoka's face twist into even more delirious and dizzy shows of fever than she'd shown in getting fucked. It was wild, messy, and she found herself simply unable to care about restraint. She just let herself go, pushed to another orgasm from being peed inside of, the most delightfully twisted and slutty of all surprises to reveal herself capable of.
By the time their bladders were empty and the pleasure was at an end, everyone in the room was on edge and waiting impatiently for their chance to fuck her, too. "Okay, students. It's time to make sure the birthday girl gets what she deserves." He lifted her up, still impaled on his cock, and guided her onto a table nearby, and in a flash, boys were rushing in to get a piece of her. All Might's cock pulled out, leaving piss and jizz to spill out of her as she writhed in delight, only to have another cock ram into her pussy and start to hammer away. Two dicks shoved into her face, and she was about to start jerking them off, only for them to both begin hosing her face down with urine too, leaving Kyoka to open her mouth in delight and explore the realization that her little accident had just set the tone for the gangbang to follow.
She couldn't have been happier. This was the birthday treat she needed.
