[Ape TF, Cock Growth, Filth, Farts, Scat]
Niijima Makoto was an overachiever. There was a reason why she had become Class President after all. But that, combined with her workaholic older sister weighing down on her day in and day out thanks to how much she projected on her after every long day at work, combined with how much work went into being a class president, and she very much wanted a way out of this life of hers.
It got to the point where she outright just wished for her life to be simpler. Not unlike the kind of life that the monkeys lived. She had seen them peacefully idle around during her study, through watching a nature documentary to try and gather a few notes. If her life was like that, where she didn’t need to worry about anything and just had full control over the pace of everything… Then she’d be happy.
However, as she fell asleep that day, that wish was perverted thanks to a certain entity hidden deep within the subconciousness of mankind. An entity that wanted nothing more than for all of humanity to fall under its control. And if it were to grant a little wish that would make her blissful in exchange for being one of its pawns… Then surely she wouldn’t complain, right?
As she snored away, the wish at the core of her being slowly came true, as stray hairs of fur started to grow along her pelvis…

“Niijima. I know you’re a filthy fucking ape, but keep your behavior to the breaks. I know it’s hard, but you’re disturbing everyone when you act like this.”
Makoto blinked as she snapped back to reality. What was her teacher talking about, exactly? What had she been doing to prompt that kind of lecture? Surely there had to be a mistake, she would never act up in class…
*BRAAAAAAAP*
The Class President’s cheeks flushed the brightest red they ever had, as she became dangerously aware of the bioweapon-like gas that left her cheeks. And the voices of all of her classmates gagging in response to the awful stench. What… What just happened?
“God! Okay, fine, don’t bother trying to fix yourself. You’re way too stupid, I should’ve known.” The teacher, the ever-sexy Sadayo Kawakami, just sighed as she rubbed her temples. She was going to need a lot to drink later tonight before her nightshift.
“W-Wait, there has to be a mistake-“ Makoto tried to speak up, only for her ass to spread itself far apart and for her donut to make its way out from between those cheeks as it let off yet another powerfully and horrendously scented fart, a powerful blast of green covering the room as her fellow students groaned and bemoaned their current existence.
“Stop talking!” Kawakami said as she slammed her fist against the blackboard for but a second, bringing silence to the classroom. Beyond the extra fart that left the uncouth girl’s cheeks. “Thank you.” And just like that, as if the fart had served as some sort of approval, she went back to drawing diagrams on the blackboard.
Makoto was in distress as she looked at herself. Why was she farting like this? Why was everyone acting like it wasn’t out of the ordinary for her to fart this badly? And more importantly, why weren’t they doing anything to stop it?
The first of those answers were simple. She had a very upset stomach because she had eaten something bad. Apes like her did that rather often, which was why she always ended up making a horrible mess of the room she was in. The second was because she had been an ape for quite some time. Ever since she had been flown to Japan after they discovered that she was sentient and able to converse with humans, she had been given preferential treatment, even though she really didn’t deserve it because she was dumb as bricks. And finally… Well, it really wasn’t out of the ordinary. As an ape, it was utterly impossible for her to be in control of anything she did. So they just accepted that it would happen while they housed the country’s most pampered student.
Of course, Makoto could tell that there were quite a few things wrong with all of that information. Namely that she hadn’t been an ape for more than a few minutes as most. She was certain that she went to sleep as a human. But her body disagreed, as another violent fart vocalized its exit from her bowels with a sharp *PRRRRFFFTTT*
Trying to argue against the world and her body was a lost cause. So instead she probably just had to try and figure out what exactly was wrong with her. And that came in the form of looking at her body and really taking in just how much of an ape that she had become. That way, she’d at least understand what she had to do.
Makoto grimaced as she looked at her body for the first time ever since she woke up. She was covered in deep black fur. Like, not entirely to the point where she had turned into an outright animal, but just enough that she couldn’t see her skin. Only by looking in a mirror she casually swiped from a fellow female student, her mind not processing that stealing was a bad thing, did she realize that her face was thankfully still human. Hell, most of her head was. The transformation was mostly localized below her neck, leaving her with such a pretty face and yet such an utterly disgusting body that it was a wonder that she ever became a student in the first place.
Hell, just looking at her body, beyond the fur that made her look like a dirty animal who couldn’t keep her farts in check, she could see and feel the muscle that covered it. As filthy as she was, she was almost just as strong. Like, she was pretty certain that she could break at least a couple boys’ skulls with a punch. Maybe even lift a building. Buildings weren’t that heavy, were they..?
Makoto shook her head. Even just trying to think was making her head hurt, and she was making really dumb observations. There was no way that an animal could lift a building, no matter how strong it was. And if she had really turned into an ape, then she wouldn’t be able to lift something like that.
As the students around her did the best to try and ignore her, despite the shotgun of gas that her ass had become as it pumped out more and more farts the more she tried to think, her thoughts slowly but surely drooled their way down the drain inside her mind. Making it harder and harder to… to…
Makoto started drooling normally as she looked down between her thighs. And she saw something that should disgust her, yet the ape part of her brain was winning out a little bit more than it was.
There was a fat black cock between her thighs. Just as jet black as her fur, yet the skin itself was black. It made it look ready for a good fuck, and…
N-No, she shouldn’t be enjoying the idea of having a cock. She was a girl! She was a human girl, who didn’t have the strength of an ape and the cock of an ape and the appetite of an ap-
*splurt*
While her mind tried to argue against her current state, her hand had done a good job for her. She had wrapped her fingers around that shaft, stroking and panting as she felt her body trembling. It felt really good to play with herself with a hand this big. Every little wrinkle of her stronger body strapping that thick shaft between them, giving her the experience of a lifetime…
God she just wanted to cum real bad. She wanted to cum inside her teacher, like she had done so many times before, or inside Ann or one of the others, or…
“Niijima! Outside!”
She heard the Teacher calling for her, and she started blushing as she snapped back to normal. Even when reality had changed this badly, it seemed like she wasn’t allowed to cum in class. What a shame. She had just gotten real nice and hard too, now she was going to waste her stiffy.
Makoto climbed out of her chair, and like the ape that she was, walked on all fours. Using her knuckles to push herself out of the classroom, all while everyone kept watching her and the gassy trail that left her cheeks as she finally left them in a relatively calm state thanks to all of her farts being filtered out by the windows opening just a few moments later.
Kawakami sighed a little and grit her teeth. Damnit, that dirty ape was wasting her first filthy nut of the day. She promised her that one…

Makoto was having quite the experience today. Not only had she started masturbating in class, but she was pretty sure that her ass was like a living swamp. Every few seconds, even when she walked, a bubble popped inside her disgusting hole and an equally horrid smell started to leak out. It was starting to become a problem, and it wasn’t just because everyone was being disturbingly uncaring towards the sudden change in odor in the air.
She had to do something to stop this. Stop walking on her knuckles. Stop acting like a filthy fucking ape. But most importantly, she needed to do something about the painful erection between her thighs. That fat black-colored cock of hers, so shiny and black like it was almost inhuman, was becoming a problem as it throbbed. It was making her pant and groan, because her heavy balls were begging for release. Not only that, but she could physically feel a bit of the dirty cum from the last few days stuck inside her urethra. She needed to get rid of that cum first, then she could cum properly instead of just squirting out little pitiful droplets.
“Makoto? You came to see me this early? You shouldn’t have, you’re the best girlfriend a girl could ask for.”
The furred ape with the beautiful face blinked as she looked at the source of the voice. And her cock started drooling a trail of pre down the length of it, because one of the most beautiful girls she had ever seen decided to greet her.
Okumura Haru. She was… A friend would stretch it, but an associate was right. So why was she implying they were girlfriends..?
Oh, of course. Because they were the best lovers. In fact, she was the one that had funded the ape’s travel to this country. And the second the two met, the ape went to town on her. Pinning her down with her powerful hands and slamming her cock deep into that fat pussy. It was such a rough fuck that it wasn’t surprising to see the girl still a bit out of it, to the point of wearing the same stockings that had been torn during that first encounter. And a subtle growth on her belly, the sign of their first brood developing healthily despite their constant fucks.
Makoto panted as she looked at Haru. She was doing her very best to avoid giving into the more beastial parts of her brain at this point. But it was hard. Especially when she was faced with such a pretty girl. Ah… She just wanted to fuck her so badly. She wanted to empty her dirty nutslop straight into her womb and use it as a dumpster for her piss too…
Haru smiled as she saw the desperation on the cute and not at all girly ape as she slowly started squatting down. “You know, I’ve been trying to think of a way to get you in the mood, and… And I think this is the way…” She muttered as she started groaning and pushing, her panties starting to shift and twitch in turn. Why did she even wear those when her leggings were torn to allow her girlfriend easier acc-
That question was quickly answered as a fucking fat turd pushed out of her cheeks and left her gasping and panting as she blushed as brightly as possible. The most dignified and rich girl that the ape had ever laid her eyes on… Shat herself and made her panties bulge out, almost as if she was just as undignified as any other animal. All while panting, her nipples poking through her sweater…
At that moment, Makoto lost her fight against the ape that held her name. The neurons inside her ape brain activated, and she grabbed ahold of the girl with the shit-filled panties. She slammed her against the ground and mounted her, just like when they first met, howling like any other ape would when excited to the core…
Haru felt only slightly disgusted as she was forced onto the ground and the seat of her panties was forced against her ass. That fresh hot shit smeared across her cheeks was enough to make many puke, but she endured. Because her dear Makoto loved it. Why else would she go so crazy when she saw her defecate herself..?
Makoto howled as the wild animal inside her went loose. She used her grip on the plump-hipped sheep-haired girl and slammed her cock straight into her used pussy. The only cock that could fit that cunt at this point was hers, as she rapidly plapped it as quickly in and out as she could. There was no way that she was about to let this opportunity slip her by.
The two lovers moaned in unison, their intimate union being unlike anything else. And everyone around them just ignored them, because this was something completely ordinary to them. An ape like Niijima making love to Haru was like the other Niijima fucking somebody in court, an all-too-common occurrence…
Just as quickly as they had started fucking, because Makoto was a pitiful quick shot, the ape let out a painful groan as she climaxed. The hardened pieces of her old cum fired off into the sheep-haired lover’s womb, while a stream of thick and yellowish cum poured right in as well, completely drowning anything that might be in there. At least, anything human. Apes like her would be able to survive, and so would their children.
As Haru let out her own orgasmic cries, Makoto ignored them. She just raised her ass in the air and started defecating just like her lover had, except her fat serpentine shit was just as big as her arm, and it fell down onto the ground instead of harmlessly inside a pair of panties. It’d be up to somebody else to clean up her mess, that wasn’t her problem.
All that Makoto did was listen to her instincts. And when it wasn’t telling her to make a complete mess of things, it was telling her to breed and then relieve herself. And once she had relieved herself, she was ready to fuck again. The cycle would continue, and the pile of shit underneath her would grow as the minutes ticked by, people growing more and more discontent in the process all while the two lovers had their filthy fun.
This was a normal day in the life of Niijima Makoto the Ape. Once she finally tuckered out, Haru would bring her home so she could stay in her apartment, together with her sister Sae. And then they could take turns ruining her further, like they always did. This was how reality had changed…
And in the end, it was what Makoto had wished for. A simple life, just like those monkeys she had seen on TV. She just never realized how filthy they could really be.
