Work Text:
Mina Ashido had a pep in her step this fine Monday morning, after a relaxing weekend she was ready to get back to another five days of heroics education! Well... she was ready to hang out with her friends again. Hopefully they weren't too upset about last Friday. They shouldn't be, she was basically holding in all her good farts!
The pink girl whistled a tune to herself while she walked along the sidewalk, backpack slung over her shoulder casually. This was gonna be a good day, she could tell already.
With a swivel on her heel, Mina turned right at the front gates of the illustrious U.A. High School. Every time she passed through them, she looked up at the big gold letters and thought of all the amazing heroes that have come out of such a fine establishment.
Then she‘d think about that time she hotboxed Jiro in the girls' bathroom and snicker to herself while walking onto the campus.
And no sooner then she stepped onto school grounds could she feel a dark, disturbing presence quickly approaching from the side.
"Hey there, Mina! You're looking sexy as ever today." Mineta struck, scurrying over on his two little legs to the girl's side, an unearned smug grin on his face. "Where ya goin', beautiful? Didn't you hear about class today, we're g-"
Mina didn't even blink before she sped up enough to step in front of Mineta. The grape boy couldn't comprehend it, it was all such a flash. In an instant, Mina had lifted her skirt up, presenting her two fat pink cheeks, half-covered by a pair of black panties. If he had enough time to realize what was going on, Mineta would've made sure to burn the memory into his mind, but alas. Life was intent on stomping this grape into wine.
FRRRBBLBBBBBBBPPPPTTTTTT!!!
Mina didn't stop whistling, even as she jutted out her ass and blasted a cloud of absolute stench over the pervert. Almost immediately, Mineta felt like he had been plunged into a scorching sauna, the warm blast of eggy smells blowing over him with no mercy.
The Alien Queen was in such a good mood, she didn't bother checking back on the boy when she heard him thud to the ground. She kept on with her strut into the school itself. This was gonna be a good day, no amount of perverts would stop that.
The door to Class 1-A slid open and closed right after as Mina stepped inside, her whistling coming to an abrupt stop.
"Where, uh..." Mina's raccoon eyes blinked as they scanned across the classroom. "Where is everyone?" She laughed nervously as she was confronted by significantly less people than she expected.
In the class, staring her down, were people she would've been happy to see if they weren't giving her such stink eyes. Tsuyu Asui, Momo Yaoyorozu, Kyoka Jiro, Toru Hagakure and Ochako Uraraka all sat at desks close to the front of the classroom, their notebooks all open and confusingly enough in their hero costumes..
"Am I late or something? It's only like, 7:30, isn't it?" Cautiously, Mina took a step forward, extremely unnerved. But that growing tension was instantly paid off as the door loudly slid open behind her, scaring the heroine out of her pink skin.
"Alrighty, ladies! Are you ready for this special little lesson?" Mina was busy making sure her heart didn't beat out of her chest, but she could recognise that voice from behind.
"M-Ms. Midnight!" She laughed, panting slightly as she lowered her books down onto a clear desk. "You scared the crap out of me there!"
"I'm glad you could make it, Ms. Ashido." Midnight stepped past Mina, dressed in her usual shockingly-tight costume. Mina was pretty sure she liked dudes, but every time she saw the sway in Ms. Midnight's hips, she had to double think herself. Not to mention the pure size the pro hero displayed. She thought Momo had the biggest butt she had ever seen, but Midnight made sure the rich girl was actually a distant second.
"Now, as you all know, Mr. Aizawa has taken the boys out for a bit of extra training, at my request." Midnight strutted her big fat ass up to the front of the class, keeping Mina's eyes glued to her as the troublemaker sat at her desk. "Which means that today, we're having a very special, ladies' only lesson."
Mina was, admittedly, starting to get worried. Sweat began to drip down her forehead, hissing as it dropped against her desk, burning a hole through it. Why didn't her friends say a word about this to her? Were they meant to study for this? Are they still upset about what she did on Friday?! It was just a prank! A joke!
"And in this lesson, we are going to be learning about..." Midnight began, humming as she began to write on the blackboard. Her rear wobbled like twin bowls of jello as the Rated-R Hero bounced up and down - it was so distracting that Mina didn't even realize what she was writing until the woman moved to the side.
The pink girl could've died then and there.
Written across the board in chalk, it was quick and to the point. B U T T S .
" Shiiiiiiiiiiit ." Mina groaned, slumping down in her seat.
"Ah, close, Ms. Ashido, but you didn't disrespect your friends quite that badly." Midnight corrected, cocky smirk on her masked face. Then, nonchalantly, the pro hero tossed the chalk up into the air before she span around and popped her ass out with perfect timing. The chalk pinged off her fat cheek, flying right into Mina's forehead like a bullet from a sniper rifle.
It was a perfect shot, the projectile knocking Mina right out of her seat and down to the ground below.
"Your classmates told me all about your funny little prank, and really, I'll give you some props. I used to do the same thing when I was your age. And also when I was in college. Aaand last week." Mina blinked slowly as she groaned, rolling back and forth on the floor. She could only just make out what Midnight was saying, too discombobulated by the chalk shot.
Not that she had time to be confused as with each blink of her eyes, she could see more and more of her friends begin to surround her downed form. None of them looked happy. Then, to complete the 18-karat run of bad luck Mina was having, Ms. Midnight joined in. The smuggest of smug looks on the teacher's face as she placed her hands on her hips.
"But do you wanna know the difference between you and me?" The woman crouched down to get more on Mina's current level. "My farts were so bad, people didn't even dare to try and get revenge on me." With that reminder finished, Midnight popped up, entire body jiggling from the sudden movement.
"Alright, girls, aim up!" She snapped her fingers and, on cue, the five girls all span around to turn their backs to Mina. "Put that early breakfast to good use! Nice and orderly, like we practiced. Make your teacher proud!"
Mina really didn't like the sounds of that.
"W-Wait, girls, we don't have to do this! I was kidding around! I-I didn't want to hurt anyone's feelings or anything! Really, it was a jo-" None of the girls cared to listen, to the point Momo decided to shut the pink girl up the only way that'd work.
The rich girl went into a freefall, collapsing right onto Mina's face, crushing the Alien Queen under rear. And what a rear to be crushed under. As mentioned, Yaomomo had one of the thickest rears Mina had ever seen, certainly the biggest of any student in UA by a big margin.
Momo adjusted her twin beachballs to and fro on Mina's face - usually it's size wasn't something she took pride in, quite the opposite. But in this case? She had to admit that her big ass was going to come in handy.
"I really didn't want to have to do this, you know I have problems with my flatulence already." Momo bit her lip as her stomach grumbled lightly. "But, what you did to us last week was really mean, Mina. And this is the only way you'll learn your lesson, so-"
PPRRRLBBBMMMMMHBBbBBbbBBBBBBBBBBuurrrmmmmpplblblbblpPPHBBBBTTTTT!!
-"Mina, this isn't a punishment. It's... an intervention." At least, that's how Momo was going to justify doing such unsightly things, it was like helping a friend! Naturally, Mina didn't see it that way. In fact, she didn't see anything besides blackness on account of Momo's giant ass squishing her entire head down.
It's sad that deprivation of one sense can amplify another, and never had that been more true than this situation. With her eyesight completely blinded, it allowed Mina's sense of smell to ascend to unforeseen heights.
This was a very bad time for that.
The rip roared all over Mina's unwilling face, rumbling with a force not even her own gas could compare to. It was so powerful, Momo's asscheeks wobbled from side to side, like it was slapping Mina to make sure she didn't pass out just yet. Which was necessary since the only air going into the pink girl's lungs at that moment was tainted with an unspeakably wretched stink.
Momo indulged a bit in her breakfast that morning, swallowing down a cartoonishly large stack of pancakes which, in hindsight, wasn't the best idea. As sweet and fluffy as they were going in, coming out it was a whole different story.
The pink girl kicked and screamed, throwing an absolute fit under the huge ass. This was repugnant, disgusting! What kind of monster would do this to another person?!
FRRLMBMBBBBBBOOOOOoOOoooLLLLRRPppPPPpppPPPPPPPPPPTTTTT!!
"J-Jeez." Momo winced, blushing as she lifted one of her heavy cheeks enough for that fart to fully slap out.
"Hey, not bad kid." Midnight chuckled, placing a hand on Creati's shoulder. "Keep eating like you do and maybe you'll be able to outfart me some day! Just kidding. I'll be dead before I let that happen."
"I wasn't exactly planning on it anyways." The thick student laughed back nervously, face a bright red as she climbed back up to her feet and was about to walk away when-
" Ahem ." She frozen mid-step when her teacher coughed. "I think you're taking something that isn't yours." Momo almost didn't want to look, she already knew what happened. One check over her shoulder confirmed her suspicions. There was a tuft of pink hair sticking out of her cheeks. For a girl that thick, it was the equivalent of getting gum stuck on your shoe.
"H-Heh, sorry." Momo reached back and pulled Mina back, peeling the girl out of her deep crack. "Sorry, Mina."
"Ah! No need to apologize, did she apologize for what she did last week?"
"Kero, kero. She didn't even feel a little bad for it." In a shockingly angry tone, Tsuyu stepped forward, shooting her tongue out and wrapping it around Mina. " Ehh'll ayke er fra ew ."
"Pardon?" Momo questioned, but Tsu was in no time to give answers, recoiling her tongue back with force and snatching Mina away. The Alien Queen was sent spinning like a dreidel towards the frog girl, before being stopped suddenly. She was grateful for a moment, until her head stopped spinning and she realized that what ended her rotation was a pair of big, green basketballs.
"Fu-" Mina was censored in the most humiliating way possible.
BRRRRMMMMFFRRBBBBBLBLBBBTTTTT!!
Swampy. Just like the one she gave Tsu last time. Turnabout's fair play.
Mina's nose rubbed against the latex of the frog girl's costume, which was disturbingly moist after only one fart. Tsuyu wasn't wanting to play nice at all, wobbling her cheeks back and forth on her victim's face. She felt a gloved hand grip her hair before the wet muscle locking her up slapped back into her mouth.
"That was really gross sounding, kero. Too bad I don't care." Mina very much did care, on account of the thick miasma of smell attacking her cringing face.
FRRRRRRPPPPPBBB BLBLBBBBTTT!!
If Mina had to guess what dunking her head in bayou water would smell and taste like, this was it. A humid, disgusting waft of thick, chewable air carried right over and slapped it's way into the regretful girl's nose and mouth.
And that was when Mina had just about enough.
" Sorry, Tsuyu, but I've had enough of smelling your nasty ass beefers! " Mina didn't want to do this but she was pushed to the edge. She activated her quirk, which was especially powerful now since Froppy's farts were making her perspirate even faster.
Mina slammed her hand down onto Tsuyu's ass cheek, and she could hear the heroine take a sharp breath. Immediately, her acid burnt straight through Tsu's hero costume, revealing her sweaty bare skin. Mina was hoping that she'd pull away before she had to do any real damage but the frog was holding her ground.
" Sorry, Tsuyu, but I- " Mina's inner monologue was interrupted as she felt her feet slowly lift off the ground. " What the hell?! " The Alien Queen was quickly knocked out of her dominant position as she removed her hand from Tsu's cheek - now it was flailing around like the rest of her body.
"Ochako!" Mina spotted the culprit, having spun right around in the air and coming face-to-upside-down-face with the girl puffing her cheeks out. "You better let me down right now! You're all acting crazy!"
Uraraka stood her ground, eyes narrowing as she held her breath, fingers pushed against one another.
"F-Fine! I'll make you drop me!" The upset pink girl began to swim towards Uraraka. Or at least, she attempted to. No matter how hard she tried, she was still floating higher and higher until-
"Ow! Ochakooo! I just hit my head on the roof! This isn't funny anymore! And- wait, what are you doing?!" Mina was distracted enough by her head smacking the ceiling to notice Uraraka getting into position below her.
And then she released. In two ways!
Mina screamed as she was dropped from high up, wincing her eyes shut as she fell right into two pillows. Two giant, rancid pillows. Her nose slipped right in between the black cheeks, pressing against an already blowing pucker.
Because the second Uraraka stopped holding her breath, her ass began exhaling.
BBBBBLLLLLOOOOOOOMMMMMPPPPPRRBBBBBTT!
Mina fell into it at around the six second mark, and it kept going to double, then triple that length. She could feel how the gas bubbled beneath Ochako's suit, inflating out the rear of it slightly before the weight of Mina's head pushed down on the nasty air and spread it out across her entire body.
If only the smell stayed inside too.
But no, plenty of fart particles snuck their way out of Uraraka's suit and smuggled their way up Mina's nostrils. A heavy eggy odor forced its way inside, filling every single Planck it possibly could. She would've put her money on them being meatier-smelling but, that may only be because of how chunky Uraraka's cheeks were.
The pink girl tried to lift herself out of the ass when she hit a roadblock. Her fluffy hair smacked right back into something soft and jiggly and - it was an ass, of course it was.
"Uh-uh, you aren't going anywhere." And it was Jiro. This wasn't Mina's day.
The sound heroine dropped her weight down, slamming Mina's face right back into the crack it was in just a few seconds prior. And now she had become the meat in an ass sandwich.
FFFFWWWOOOOOOOMMMMPPPPPPPPFFFFFFF!
Jiro's gas was, more than anything else, booming. Even Midnight covered her ears and winced at the ringing force. Thankfully, Mina mostly avoided the smell but that was mostly at the cost of having to snort Ochako's crack instead. Speaking of which.
FRRRMMBLBLBBBBOORRPPPPppPpPpppPPPTTT!!
Damn those eggs. Uraraka's ass responded to Kyoka's, grumbling out an equally long bubbler to match Jiro's deafening bomb. They had Mina trapped in a dutch oven made entirely of ass fat.
She could barely think. By the time one fart ended-
BBBBBBWWWOORMMMMBBBBFFFFFTTTTT!!
Another one began.
BPBPbpppbllblbbbbbooOORRMMMBBBBPPHBBBBTT!!
Like a see-saw of gas, Jiro and Uraraka took turns blasting opposite ends of Mina's face, blowing her hair in changing directions with each rip. It was a game of tennis, except they were trading Mina's ire. Not that she had much anger left, she was mostly just defeated at this point. Each rip further breaking her spirit until she went limp between the two asses. She wasn't unconscious, but she wished she was.
"You feeling any struggling back there?" Jiro asked callously, giving her rear a quick grind back and forth.
"No but, I'm kind of scared to break the seal. I think it's gonna smell really bad." Uraraka blushed, although she knew she had to do what she had to do.
"Alright, fine. Yo, Yaomomo, can you hook us up with some clothespins or something? Then it'll be Pinky here's problem." Shy as she was about the whole thing, Momo couldn't disagree that Mina could probably serve to wallow in a bit more stink. It didn't take more than a few seconds for her to produce a share of pins and noseplugs, tossing them out to the ladies as necessary.
"Oh, no need. This isn't anything I can't handle." Midnight shook her head when offered, confident smirk on her face. Truthfully, it was pretty horrendous in there but, she wasn't about to give these girls an ego boost and let them think it was affecting her .
Jiro and Ochako put the smell-blockers on and took deep breathes - more to prepare themselves than to get in any last vestiges of clean air, since there really wasn't any left. And with that, they broke the seal.
Jiro stood up and immediately a green fog began to quickly leak out in all directions. The floodgates having truly opened and letting the joint stench of the two girls spread all over the classroom.
"S-Sorry, Mina, this is gonna hurt." Uraraka apologized, more so for the sake of her conscience than because she felt bad.
The gravity heroine span around so she was facing the ceiling, but Mina didn't fall out of her cheeks. No, her face was properly wedged in there, it wasn't going anywhere. This made it a lot easier when Uraraka stopped holding herself up and allowed her full body weight to SLAM down onto Mina, crashing the pink girl into the ground with a clunk. A bit higher up and Ochako may have indented two craters in the ground.
BBRRRRRRRMMMMMPPBLBBBBBBBBRRRRPPPHBBBBBBBBTTTTT!!!
Uraraka was caught off guard by what roared out of her backside. Even Midnight raised an eyebrow at the expulsion. The sudden drop wasn't good for the bubbly girl's gut, obviously. Before she could realize it was about to release, it was firing out of her backside.
The relief Uravity felt in that moment was so overwhelming, she couldn't even reognize her surroundings. The powerful fart practically took control of her entire body, until her only thought was to start pushing out more, extending its length into the minute plus range.
Mina would've said it was more like an hour, but that's only because she took the brunt of the release. The never-ending stream of gas filtering into her mouth and nose, gallons and gallons of the stuff - to the point where, if it was water, she would've drowned seconds into it.
But luckily (or unluckily), it wasn't water. Just putrid, wallpaper peeling gas. A rancid stench, rich in rotten eggs and ancient cheeses - and it was all for Mina to revel in.
"S-Sorry." Uraraka meekly moaned as the 1:11 of gas finally reached it's climax. The rosy cheeked girl gave her rear a gentle waft, as if they could accommodate for the fumigation she gave the room. She lifted her rear up once more, having to reach back and complete the arduous task of spreading her heavy cheeks to free Mina.
By the time Mina's head stopped spinning, Uraraka had made her distance. She was confronted by her friends all standing across the classroom from her, a mix of reluctance and satisfaction on their faces. Perhaps they took it a bit far...
"Momo... Tsu... Jiro... Ochako..." Mina began, crawling towards the four as she panted for air. "You guys are my best friends. I-I'm sorry that I did all those pranks, really. You four mean a lot to me." The Alien Queen had truly been knocked down a peg. Her hair was frizzled and messy, her face drenched with sweat, she even had a few scuffs on her face from the punishment.
"Without you guys, I'd- mmph!" Mina was stopped in her tracks, her face colliding with something. She tried to pull back but she suddenly felt something pushing on her head, keeping her in place. What was going on?! It didn't make any sense and what's with that glove on the ground and-
Shit, she forgot about Toru.
But make no mistake, Toru had not forgotten about Mina.
"Toru, wait! That's your bare butt, stop!" Momo was the first to notice the major hole (pun intended) in this aspect of the plan. "That's just gross!" Says the woman who was shaking the room with her gas moments prior.
"No way! I wasn't even going to do it until she forgot me!" Toru grumbled as Mina felt what she could only presume was the invisible girl's thighs lock around her head. That mistake was going to cost Pinky dearly.
Everyone went silent, you could hear a pin drop. But what you couldn't hear was the near-silent hiss of gas escaping Toru's ass and forcing its way up a very unwilling pair of nostrils.
Mina kicked and screamed as her nose hairs were singed clean off from the pure olfactory offensive. The awfully acrid smell puffing its way up to the prankster's brain. Fitting given how all she could sense in that moment was Toru's ass.
But even with the smell, the most damning part of the invisible girl's expulsion was just how long it was. It may not pack the punch of a Momo or Uraraka rip, but it wouldn't end. Past the minute mark, past the two minute mark, ending right before it would've passed the three minute one.
It didn't have the strength to knock Mina out, but it still packed enough of a punch to be consistently painful to the senses. It's like comparing being mauled by a lion to being bitten by a million ants. Basically - both suck.
And don't think the smell wasn't still horrific, that would be naïve. The pungent aroma finally delivered that meaty, rotten pork scent to complete the breakfast buffet the girls had run through.
As the SBD squeaked to its end, Mina felt the legs keeping her in place finally release her as Toru stood up and joined her friends across from them both. If that didn't teach her to stop pranking them, nothing would.
Without Toru's ass keeping her in place, Mina collapsed forward, face hitting the floor as her ass was up in the air. She barely moved, only slight twitches implying she was even still alive as the shock of what happened washed over her.
Groaning, Mina began to lift her head back up, just in time for two high heels to step in front of her.
"Good work girls!" Midnight clapped, smile on her face. "I think you taught Ms. Ashido a lesson she won't soon forget. Now then, you can all go join the boys outside... I'd take showers first though." The dismissed students all walked off, murmuring to themselves as they left.
"D-Does that include me?" Mina asked hopefully, although she knew the answer before Midnight laughed it out.
"Yeah, no." The teacher span around, giving Mina one last look at her jiggly ass as she turned. "Not bad though, you actually survived that. Those girls can eat ."
ggrrrggll
"But then again, so can I." She chuckled, placing a hand on her stomach. The pro hero didn't bother turning around for what happened next - she knew she didn't have to for it to be effective.
FRRRLBLBLBBBBBRRRRMRPPPPPPFFFFFLBLBBBBBBURRRRRPPPPPPPPPPTTTTT!!!
Without seemingly any effort, Midnight casually upstaged all of the girls with a fart that rivaled them all in sound, power, length (minus Toru's SBD) and definitely smell.
Even with the teacher facing away from Mina, the powerful rip still blew her pink hair back. Immediately the classroom was filled with a thick dark green smog, a single fart from Midnight able to do more damage than the five girls combined.
"Oops, sorry. It slipped out." She shrugged, beginning to shake her hips to really waft the smell out. Not that that was necessary. The beefy miasma was attacking Mina already, and hard too. Not to discount the 1A girls' assault but this fart made Momo's best work smell like flowers.
Mina hacked and gagged on the monstrous fart, collapsing flat on her stomach. She couldn't even find the strength to lift herself up any longer.
But not this was enough to make Midnight stop. The teacher lowered her ass down until she was in a crouch, hovering her plump cheeks just in front of Mina's face.
"Please, Ms. Midnight, I-"
ffffrrssslblblbbBBBBLLRRRMMMPPPPPHBBBBBBBTTTTTTT!!!
It had the familiar hiss of a softer, airier fart, but this was no little snake - it was the mightiest of anacondas. And fittingly, it's smell was constricting Mina's ability to breathe with the tightest of vise grips.
Mina couldn't even comprehend what Midnight had for breakfast. The smell had mutated that far past anything conceivable. Unless the Rated-R Hero had a hearty bowl of burning rubber and washed it down with some raw sewage.
"Really, honestly , I like you a lot." Midnight began, casually talking as she swiveled her rear. "You've got a lot of, nnf -"
FFRRLLBLBBBBRBMMMMMPRRBLBLBBBBBBTTTT!!!
"-spunk. But, don't think you're ever -"
BBRRRRMMPHBBLBBBLBBLBBBBBBBOORRMMMPPPTTTT!!
"- EVER -"
PPPRRRRRLLLLOOOORRRRRMMMMBHBBBLBLBBBBBRRRRMMMMPPHHBBBBBBBBTTTTT!!!!
If the last two farts were the stretches to get ready, then this bomb was the sprint they were prepping for. One could hear how long this fart burnt for, but it wouldn't compare to the sensation of experiencing it. A written description can only do so much to paint a picture, and there are no words that could describe gas on this level.
Midnight didn't only rumble the classroom, her influence stretched out to cover the entire building, rattling the schoolgrounds stronger than most earthquakes could. Yo Shindo, eat your heart out.
Not that anyone's appetite would be able to survive any kind of prolonged exposure to such a release. In fact, if anything, they're more likely to lose their lunch than down any.
"-going to take my title away. I'm the gassiest pro hero there is, and I'm the gassiest pro hero there ever will be. Settle for second place, alright?" Midnight didn't realize yet but she wasn't really talking to anyone by that point. Mina was long since knocked out, that last explosion makde sure she wouldn't be waking up for a long time.
Many hours later...
"Huh?!" Mina shot up from her lying position, panting for air as she looked around. The lights were off, the sun was setting, and there was no sign anyone had even come to check on her. "Hello? Anyone?"
She was about to stand up fully when she noticed something - a note, tapped to her chest. Maybe it would be an apology from Momo for going to far. Or maybe she'd get a week off school for suffering through that! Today had taught her nothing about being so hopeful.
With a teeaaaar! , Mina pulled the note off and read it.
Her smile and optimism, gone.
" Because of your outstanding work in class, we are giving you a free two weeks of work under a real pro hero! You will begin your work under Mt. Lady (Yu Takeyama) effective tomorrow . Be sure to have fun and learn lots!"
Mina collapsed back on the floor.
