Kyouko’s feet were pounding the track beneath her, and despite the harsh sun burning her skin and the sweat stinging her eyes, she couldn’t wipe the grin off her face. The adrenaline shooting through her veins, the cheers of the crowds in the stands, the elation whenever she passed another runner-
And she had many to pass as she made up the ground Pinkie had lost at the beginning of the race. But that’s why she had been the one to start things off.
So that the others could close things out.
Kyouko could honestly say that she didn’t give a rat’s ass about the sports festival, really. She didn’t care if their class won or lost. There was no price, no reward, no punishment…
But it was a different story when Kyouko was directly competing. She didn’t care about winning collectively, but she was planning on winning every event she participated in. Including this relay race.
Madoka had started them off as the weak link in the chain. Honestly, she wouldn’t have been included, but Homura had said she wouldn’t participate unless her girlfriend was included, and Homura was the third fastest runner in the class.
She’d easily made up the distance Madoka had lost them, and now, it was up to Kyouko to actually create some distance with the pack. And then, Mami would close things out.
So, that was what Kyouko was focused on. Pounding the track, and Mami in the distance, waiting for the baton pass.
But to be honest, most of Kyouko’s attention was swallowed by Mami’s figure in the distance, quickly being closed in on.
The blonde barely managed to fit in her gym clothes, her large tits stretching her white t-shirt to its limits, her shorts being eaten up by her phat ass, especially as the blonde put in some last minute stretches. It was a tad too late for them, but Mami probably needed them, given what she was lugging around while running.
Kyouko was panting as she ran, and not just because of exertion. She was already imagining Mami’s tits bouncing as she ran, and her cock throbbed in her pants at the image.
Yeah. Her cock. Some remnant of a particularly lewd Witch’s Labyrinth that wouldn’t go away even after several days. She was stuck with it, as were Madoka, Sayaka, and Homura. Mami hadn’t been able to make it, which was probably a good thing, even though the blonde felt differently.
Only Mami could see avoiding growing a cock as failing her juniors, but what else was new. The girls had quickly grown used to their new appendage. Though it sometimes got in the way, Kyouko didn’t care much, to be quite honest.
The worst bit was that Kyouko’s new cock really liked Mami’s body, and it liked making that fact known. And usually, that was a feeling Kyouko either fought or pretended didn’t exist.
But right now, Kyouko saw an opportunity. Rather than fight that feeling, Kyouko embraced it. She used that arousal and desire to make her legs pump faster, make her mind more focused as she stared at Mami’s straightening form, preparing herself for the baton pass.
And it was working. Kyouko was leaving the other runners in the dust as she ran toward Mami, her heart pounding blood into her hardening cock, the organ somehow not impeding Kyouko’s sprint none even as it pushed against her bloomers obscenely.
But Kyouko didn’t even notice. Her focus was absolute. So absolute, that she also didn’t notice the way the dormant Witch’s magic was slowly but surely being stirred by not only Kyouko’s arousal, but also her acceptance of that arousal. Her use of that arousal as it fueled her legs, making them pump faster and harder. And as the magic was roused, so was its influence.
Kyouko’s world narrowed with every step. First, the crowds and their cheers in her peripheral vision vanished, soon followed by the other racers. Then the track beneath her, and even her own body, meaning she was completely unaware of the way her cock was slowly but surely growing and stretching out her bloomers obscenely, as if its size was directly proportional to the Witch’s influence.
Her whole world was vanishing, leaving only her objective untouched.
Mami.
Kyouko was staring at Mami’s lewd body like it was the only thing that mattered in the world, which it was to her thanks to the Witch’s growing influence.
Mami!
She was panting, running as fast as she could, not even caring that her bloomers had finally given up the ghost and been ripped apart by her erect cock, pointing directly at Mami’s backside like a spear.
“MAMI!”
Mami straightened herself back up after having finished her stretches and took her position. She wasn’t used to participating in these kinds of events, always too distant or too busy with Magical Girl business to really carve herself a spot in her class, but she was more than happy to do so now that she had the opportunity to! Especially since it was so clear how much Kyouko wanted to win. And she couldn’t let her cute kouhais down, could she?~
That’s why she was ready (and eager) to give it her all-
Mami blinked as she felt her Soul Gem react in her ring. A Witch? Here and now!?
No, the reaction was too weak, too weak even for a familiar… A Kiss then? Maybe, but she wouldn’t usually be able to feel a Kiss without actively looking for it… Not that she could actually pull out her Soul Gem and start a search in front of everyone.
She looked all around her anyway, trying to find the source of the dark magic with her regular senses, to no avail. Everything seemed normal as far as she could see-
“MAMI!” Kyouko cried, making the blonde jump. She was still in the middle of a race!
She started running as she realized how close Kyouko’s voice had sounded, and hurried to retake the proper position to receive the baton pass, just in time to feel the aluminum slap against her palm.
She grinned, and started running in earnest-
“MNGHOOOOOOOOOH!~”
Before crying out whorishly as her guts were suddenly stretched out!
A huge weight had landed on her back as Kyouko had pounced on her, clinging to her like a monkey. But the real shock was Kyouko’s cock being sheated into Mami’s pussy, having easily torn through her bloomers and speared into her cunt.
The only way for Mami to not suddenly faceplant from the increased weight was to keep running and carry her forward momentum, which was only possible thanks to her Magical Girl nature. That was also the reason she could take a foot of cock punching into her womb and only feel mind-melting pleasure rather than collapse in pain.
“K-Kyouko, what are you doiiing~” She mewled, panting as she struggled to carry Kyouko on her back as she ran. For a moment, she was worried that people would see what was going on, but given that Mami could feel her Kouhai’s balls nestled tightly against her ass, she doubted there was anything to see except Kyouko demanding a piggy-back ride at the worst possible moment.
The redhead was panting madly in her ear, moaning softly with every one of Mami’s steps. “Ha~ I can’t TAKE it anymore, Mami~ Your slutty fucking body teasing me every damn day!~” She cried, her hands dipping to grab onto Mami’s tits through her shirt, nearly tearing the white fabric as they dug into the fat like her boobs were a mix of stress balls and handholds. Mami’s legs buckled for a second as pleasurable lightning shot up into her brain, but only just managed to keep her balance.
If she fell, not only would they both eat dirt, but they would also lose the race!
For some reason, that still seemed important to Mami, even as she felt other worries fade into the background, eclipsed by Kyouko’s voice in her ear and her cock in her pussy. Worries like her still shining Soul Gem trying to warn her about something that she couldn’t care less about with her kouhai’s scalding hot cock throbbing against her insides~
“This is your responsibility, Mami, so take care of it!” Kyouko cried, before beginning to hump into Mami, her hips shifting barely an inch of two back and forth, sawing into Mami’s rapidly-growing-drenched pussy, and making the blonde moan, stumbling again, but she refused to fall.
Yes~ This was her responsibility for having such a slutty body~ She managed to avoid being cursed by that Witch, so it was her responsibility to take care of her kouhais~
The thought crystallized in Mami’s mind as she ran as fast as she could, easily accepting Kyouko’s desperate relief-seeking as normal.
The blonde was panting in both pleasure and exertion, but despite her best efforts, there was no way she could actually keep the lead Kyouko had given them.
Runners passed them one by one, but Mami refused to give up! Her kouhais were counting on her after all~
She forced herself to pick up the pace, and Kyouko moaned lewdly as Mami’s cunt clenched around her cock, not that that did anything to slow her thrusts. What it did do was convince her to rip Mami’s shirt and start groping her chest directly, her fingers digging into the milky fat eagerly and making Mami’s eyes roll into the back of her head for a moment.
Fleetingly, Mami felt a lance of shame and worry as her chest was exposed, but she barely had the time to acknowledge it before it vanished, replaced with the pleasure of Kyouko’s touch and cock and the eagerness to win.
She kept running, and soon managed to somehow catch up to the next girl running the relay race.
For a moment, the runner’s head turned slightly to see what was approaching, only to do a double-take as she saw Mami’s bare tits held in Kyouko’s hands. She gaped for some reason, making Mami blink-
Only for her to look away as the girl fell to the ground with a moan, her eyes rolling into the back of her head as her hand dove into her pants, frantically masturbating as Mami passed her.
Mami didn’t even notice the girl’s cry of pleasure, too focused on her own pleasure-
But mostly, the next girl in front of her.
That one already had a hand down her bloomers, no doubt frantically fingering her pussy, shooting looks back toward Mami, but soon, the blonde had caught up to the struggling girl.
Her eyes went from Mami’s pale tits to Kyouko’s hands on them-
Kyouko growled in Mami’s ear, and her humping turned into full-on fucking, her hips slamming against Mami’s ass as she hollowed out her pussy, before stretching it out again on the next thrust, making her howl, soon echoed by the other runner as her bloomers exploded off her body, her hard cock erupting like a geyser all over the floor, before she fell to her knees, panting like a wild animal, already jacking herself off before her previous orgasm faded.
Mami had managed to make it back to second place, even though Kyouko’s cock kept somehow stretching her more and more with every thrust. You’d think that Mami’s pussy would already be snug as a glove around Kyouko’s cock, but no! It was as if everytime she thrusted, Kyouko’s cock was bigger than it had been on the last thrust!
Mami moaned whorishly as she stumbled past the girl that had been in the lead, ignoring the way she was kneeling on the ground, sucking on the head of her own cock as she jacked it off desperately, her front already covered in her own cum- not that it stopped her eyes from rolling into the back of her head as she blasted another thick load of cum into her own mouth.
Mami could barely see in front of her as she did her best to walk straight, stumbling and staggering with every one of Kyouko’s womb-destroying thrusts, pleasure shooting through her mind as if her cocky kouhai was fucking her brain directly~
But stagger she did. One shaky step after another, she ate the race track inch by inch, until she stepped over the ribbon indicating the end of the race, discarded to the floor by the girls who were supposed to be holding it. They were too busy sucking one another off to care about it.
And Mami was too busy cumming her brains out. She collapsed to her knees as Kyouko bloated her womb with her oiling hot seed in victory. She gurgled happily as Kyouko’s feet finally found the ground, which allowed her to fuck Mami properly, completely unimpeded by the fact that she was actively cumming inside the blonde.
Mami smiled as the rest of her team swarmed her, hard cocks bobbing up and down as they ran. Even Sayaka was here to celebrate,even though she wasn’t on the relay team~
Madoka didn’t waste a second before jumping into Mami’s arms, making the blonde shiver as the pinkette’s cock slid over her exposed stomach. “You did it Mami-senpai!” She cried happily, her hips thrusting against Mami’s stomach, poking at the bottom of her boobs as she did.
Mami blinked for a moment- Madoka was quite hung, yes, but was she supposed to be able to reach her chest like this?
She looked down at herself, only to find that her boobs easily reached half-way down her stomach. She didn’t know how she had managed to fit them into her shirt earlier-
Mami moaned as Sayaka joined into the hug, her own cock slapping against her chest as she did. “Good job carrying that lug across the finish line, Mami~” Sayaka said cheekily, not that Kyouko noticed- she was much too busy doing her level best to impregnate Mami, her full balls slapping against Mami’s pussy with every one of her thrusts.
Sayaka frowned at being ignored, but was almost immediately distracted by Mami’s heaving chest, grabbing onto it and hefting it, making Mami whine as she was manhandled.
“You really are a cow, huh Mami? How long until you start lactating?” She asked teasingly, pinching Mami’s nipple and making her cry out.
“I’m not a cow~” Mami protested weakly. She would’ve been much more convincing if she wasn’t trying to fit those words in between her gasps and moans as Kyouko fucked her into Sayaka’s grip.
“She’ll have proper udders soon, given that there’s no chance Sakura-san didn’t impregnate her.” Homura said calmly, her voice barely hitching as she masturbated her own cock, standing a small distance behind the other two girls.
“N-Nyooo~” Mami tried to protest, but it was useless-
She whimpered lewdly as Madoka’s small fingers quickly found her free nipple, and started tugging on it.
She giggled happily. “C’mon, Mami-senpai, give us some milk!~” She demanded as she toyed with her boob, and Mami’s mind went- fuzzy.
Her cute little kouhai wanted some milk. This was her responsibility.
In moments, Mami’s already large breasts engorged with milk, making them visibly inflate with the pressure, milk already pearling from her nipples to Madoka and Sayaka’s audible enjoyment.
She didn’t even have a moment to consider this development before the pair of them brought the heavy tits to their mouths, and began suckling on her nipples eagerly, making Mami’s brain somehow even foggier with pleasure as she was pressed between the three girls. Instinctively, her hands found Sayaka and Madoka’s cocks, and began jerking them off.
This was her responsibility after all~
She moaned as the two nursing girls began feeding even more eagerly at her touch, moaning into her nipples in response to the pleasure, but somehow, through the haze blanketing Mami’s mind, she managed to see Homura, still standing apart from the group, still idly masturbating by herself.
Mami licked her lips. That too, was her responsibility.
Homura blinked, and then blinked again, her sharp amethyst eyes growing slightly hazy for a moment. Her cock throbbed with arousal as her masturbation accelerated but that was no good~
That cock was Mami’s responsibility.
Homura blinked rapidly, before taking a shaky step forward, her head slowly swiveling on her neck, as if trying to take in her surroundings, and failing.
One hesitant step at a time, Homura approached the blonde, still looking confused and uncertain. She opened her mouth, a question on her lips, but it was too late.
The moment the futanari took a step too close, Mami lunged forward, and swallowed Homura’s cock in one fell swoop. Her kouhai’s cock fitted perfectly down Mami’s throat, and the blonde didn’t waste a moment properly taking care of Homura’s arousal, as was her responsibility~ Whatever Homura’s question had been turned into a lewd moan, and her confusion became pure arousal as her hands fell on Mami’s head, grabbing onto her locks, and beginning to thrust into her mouth, using it like the sex toy it was~
Mami fell into a haze of pleasure as she was pinned in place between the four girls, and with every passing moment, her entrapment only grew more and more apparent.
Kyouko’s cock felt like a pleasurable stake in her guts, pinning her in place. Sayaka and Madoka’s cocks were obviously growing in her hands with every mouthful of milk they hungrily dragged out of her tits, and Homura was apparently trying to meet Kyouko in the middle, every thrust in and out of her throat taking more and more time.
And Mami couldn’t be happier~
Or so she thought!
Because when Homura’s cock ripped itself out of her throat in one fell swoop, it was quickly joined by Madoka and Sayaka’s cocks as they stood up once more, the three girls jacking off side by side for a moment-
Before unloading a torrent of boiling hot cum together onto her face and chest.
Mami gasped as she was blasted with her kouhais seed- not to mention how Kyouko was apparently eager to join the festivities, unloading another load into her unprotected womb and inflating it even further somehow.
Mami’s gasp left her mouth an eager target for the girls’ cock to aim for, and aim they did, filling Mami’s moaning mouth with their musky seed, and before she could even think about it, she closed it, swallowing her reward greedily, before opening it again for another round, which her kouhais eagerly supplied.
By the time Homura, Sayaka, and Madoka’s orgasms petered out, Mami’s features were completely unrecognizable under the heavy glazing she’d received, not to mention her chest. The milk her tits were still leaking was completely camouflaged within the thick cum covering them.
Mami’s brain was slowly trying to recover, trying to come to terms with what she had just done. Somehow, the reprieve she had received as the four other girls came to a pause around her let her think clearly for a moment. Something was wrong here…
Mami could hear the crowd in the stands frantically fucking, moans and cries easily reaching her ears as the spectators fell upon one another- sometimes in pairs, sometimes more, like a pack of wild animals in heat. Something was wrong- She reached for her Soul Gem blindly, distantly remembering something about it from earlier-
But whatever order she had managed to assemble in her mind was knocked down when she heard some wonderful news.
“I’m taking Mami-senpai’s mouth next!” Madoka exclaimed cutely, clapping her hands together in excitement, her hard cock bouncing eagerly as she did, the middle bending under its own weight slightly.
“Fine by me- I want to fuck those udders~” Sayaka said, her cock slapping against Mami’s chest, easily piercing through the cleavage that should’ve easily swallowed it before Mami’s latest growth spurt.
“Fine. Move around, Sakura-san. I’m taking her ass.” Homura said calmly, but Mami could easily hear the note of arousal in her cold voice.
Mami’s sand castle of worries was washed away by a wave of happiness and arousal.
Her lips stretched into a smile- but only for a moment before Madoka began fucking her face in earnest.
And as she was used for her kouhais pleasure once more, she let herself be carried away by the bliss of cock, cum, and duty.
She needed to take care of her kouhais. Nothing else mattered~
