On patrol day in the city, the heroes, as always, would do their routine surveillance in case of possible crimes, although the day was quite calm in terms of crimes, it was not exactly a normal day. That particular day was the day of teaching young hero apprentices, children between 5 and 7 years old would have the opportunity to accompany one of the main heroes of the city on patrol, obviously, they had tried to solve most of the dangerous crimes the days before, and the children had been put in charge of the higher ranking heroes.
 
One of them, Mirko, had been in charge of one of the most important girls, Eri, who accompanied her by her side as they both walked through the streets, the dark-skinned and muscular heroine explained to her how the patrol worked and how they responded to emergencies, Eri listened attentively and curiously, but honestly... Mirko hated this particular day. The first few times it had been fun, but when it started to become a monthly thing, it got tedious very quickly, having to explain the same things over and over again drove her crazy. She wasn't a teacher, she didn't like it and she hadn't trained to be one, she had trained to kick villains' asses dammit!
 
To top it all off, it seemed like she was always given the worst job, always the "young promise", always the most important girl, they always asked her to be extra careful and to explain everything in great detail, it was torture, and to top it all off, she couldn't take time to eat lunch because the schedule for all this nonsense was tight.
 
Eri asked her the same questions as all the other kids before "how many villains have you defeated?, who made your costume?, do you like being a heroine?", Mirko used answered those questions even bragging about her achievements the first few times, but now, she just answered half-heartedly, giving vague answers or the first thing that came to mind.
 
"ah....yeah, I defeated like 200...my costume was given to me by the association...yeah I looooooooove being a heroine, sure" As she answered, she noticed that Eri had taken a sandwich out of the lunch box she was carrying hanging like a bag and was eating it in front of her while listening... this damn brat! Really? Mirko hadn't even been able to eat breakfast because she had to pick her up in the morning, she couldn't even eat lunch because she had to follow a stupid schedule to explain everything to her, and now this piece of shit litle girl was eating in front of her as if it were nothing!?. Mirko kept a poker face as best she could but she was furious, thats it, she had to find a way to put an end to this young heroes patrol nonsense, or at least get her ass off the list of those in charge.
 
As they continued walking and Mirko continued with her explanations, in her mind, she was thinking of a way to get out of all this...what if...what if she proved that all this patrolling was not as safe as the Hero Association thought? Maybe if a girl got lost they would cancel it...or at least stop doing it on a monthly basis. After all, they are heroes, it's not unreasonable for something unexpected to happen in the middle of the patrol, and the association is assuming that risk right?.....but wouldn't she be in trouble if something happens to Eri....nah, why would she be, this wasn't her idea in the first place, but the association's, she's one of the top heroines in the city, who would criticize her, who would even dare to doubt her, and of course they wouldn't punish her, especially if she makes it look like they had been attacked....
 
A smile appeared on Mirko's face for the first time all day, if everything went well, she would even get something to eat.
 
"Eri-chan, I think I heard something over there in the alley, I don't think it's anything too dangerous, would you like to accompany me to investigate it?" Mirko said with a happier voice than she had spoken all day, while Eri nodded with curiosity and excitement for being able to help a heroine, Mirko for her part, quickly reported something strange through her communicator to the association, so that she could use it as an alibi.
 
They both entered the alley, turning down one of the hallways where no one else would see them. Mirko pointed ahead, telling Eri to look for anything strange. She didn't explain what, nor was it necessary. The brat was so excited to help that she didn't even notice the lack of explanation. For her part, Mirko jumped up onto one of the fire escapes at the side of the alley. She had to make this look like a fight scene, so she unceremoniously ripped off her heroine costume from head to toe, tearing it into pieces, making it look like someone had attacked her as she stood naked and barefoot in the dirty alley below her.
 
Eri had no idea what was going on above her head, she was too distracted in her little fake mission, looking for clues about a villain that was never there, while the chocolate bunny above her, positioned herself ready to literally pounce on her prey, Mirko raised her bare feet onto the railing of the fire escape, crouching while she pointed her ass and calculated the distance between her and her target. When everything was ready, the heroine jumped from her position, raising her legs and spreading her buttocks, revealing her large black anus for a few seconds before falling on her target. Eri raised her head for a second to see the source of the sudden shadow over her, but all she saw was a pair of brown buns and an even darker hole right in the center.
 
She didn't even have time to scream, Mirko fell perfectly on top of her, engulfing her entire body inside her huge ass in a second, the heroine let out a small moan, but it was silenced by the sound of the pavement breaking beneath her ass, followed by a fart of pleasure that came out just after the last of her small prey entered her anus. *FFFFFFFFFRRRRRRRRRTTTTTTTT!!!*
 
"Uffff that hit the nail on the head, I should have done that from the start instead of dealing with you brats" Mirko said as she felt Eri writhing inside her rectum, the poor girl crying and begging for help. "Miss Mirko! Help! Please, the villain caught me, it's hot, heeeeeeelp!". Mirko's bunny ears heard her perfectly, but that only made the whole thing more fun, even so, the heroine thought it was better to end this so she could report the "attack" to the association and return to the real heroic activities that interested her and not babysitting. Mirko's powerful anal muscles tightened around Eri, as the heroine began to bounce on her toes like a bunny, warming up her body with the exercise, while her rectum crushed Eri from the inside, crushing her bones mercilessly, making the poor girl scream and beg louder.
 
Mirko's ass didn't even bother to suck Eri in any further, her body, used to dealing with villains, was already turning her into shit right there in her rectum, Eri screamed in desperation and pain while Mirko just hummed as she finished her off mercilessly, sweat splashing from her sexy naked body with every jump. After 5 minutes of warming up, Mirko thought that would be enough, spreading her ass with her hands, the chocolate bunny pointed her anus at the wall, and with a powerful fart, she shot the remains of the girl against the wall without any consideration, no shame.
 
*PPPPPFFFFFFFLLLLRRRRRRRRTTTTTTTHHH!!! Mirko stuck her tongue out lasciviously as she felt the shit coming out of her and hitting the wall, a good part of it sticking along with the bones "Oops, looks like I got you out too soon, meh, nevermind, I like it when they're still hard when come out" Mirko laughed, while Eri's small skull shot out at the end of her avalanche of fresh and steaming shit, the power of Mirko's ass was such that when it crashed against the wall, the skull shattered into pieces.
 
Mirko finished depositing out the shit she had turned Eri, ready to call the association with a fake message for help, giving herself a big slap on the ass as a gesture of victory at getting rid of the brat...but the moment she did...something happened, she felt her ass full immediately, as if a whole shit had just appeared out of nowhere, the surprise made Mirko release another fart, followed by whatever had suddenly appeared inside her rectum...and to an even bigger surprise, what fell from inside her anus, onto the small mountain of shit on the floor...WAS ERI HERSELF.
 
Mirko was speechless, she was sure that she had turned the brat into shit, that waste and those poop-stained bones were the girl's without a doubt... then how... that was when Mirko remembered, she had read something in the report before starting the patrol, she really didn't give importance to any of the information about the brats, but the quirks were at least interesting, and Eri's said something curious... rewind...
 
So it was that... apparently the brat could return to an intact state thanks to her ability... but how could she do it even after dying? Was it really her who activated it... or was it Mirko?... well, there was only one way to find out, and also, an immortal anal toy and snack? Mirko wouldn't pass up that opportunity!. Eri was completely disoriented and scared, she remembered being crushed and digested in a dark and sticky place, and now she was back outside...naked...and on a pile of shit and...bones? She looked up at the chocolate heroine, searching for an answer, but all she found was a cruel smile as she was lifted by the hair.
 
"Well well, I was thinking of finishing you off quickly so I could get out of this nonsense of being your babysitter...but it seems like we're going to be spending more time together today whether we want it or not Eri-chan" Mirko said in a threatening and mocking tone.
 
"Now, I think it would be a good idea for you to start by cleaning up the mess you left on my ass when you came out like the piece of shit you are, that is if you don't want to take a full trip through my insides now".
 
Unfortunately, Eri wasn't exactly in a state to respond, the fear and trauma she had been through only left her crying and begging for help... which quickly ended Mirko's patience again, who didn't think twice before putting the little girl inside her mouth, her size didn't make it difficult for her to swallow her completely, her terrified and crying face as she was sent once again into another dark and humid tunnel, which this time was Mirko's throat, could be seen perfectly from outside the stretched meat, as it descended into the heroine's stomach.
 
The poor girl was greeted by the already ready stomach acids of the heroine, if she thought the digestion in the rectum had been bad, this was even worse, but Mirko had no mercy, as she tightened her abs to begin to crush Eri once again, speeding up the digestion, putting her through hell once again for the second time that day in less than an hour, until again, the brat was gone...for now. Mirko felt the shit filling her rectum again, but she still didn't let it out, she waited... she waited and waited a little more to see if Eri would rewind again inside her anus, among the shit... but nothing happened... The rabbit heroine thought for a moment what she had done before the quirk activated the first time, then, raising a hand, she gave herself a powerful spanking on her fat ass again, and immediately felt how the brat began to fill the insides of her anus. Mirko smiled, relaxing her pucker, and letting Eri be "born" once again, falling to the cold floor of the dirty alley, and crouching down to be face to face with her new toy.
 
""Well, well, it seems I have a new ability, that means you're just a useless brat now Eri-chan" Mirko said cruelly holding Eri painfully by the hair. "But don't worry, even a quirkless girl like you can be good for something, so first, like I said before, shove that cute little face between my butt cheeks and get to cleaning up your mess!"
 
With that, Mirko stood up again, and without another word, forced Eri's face between her big, sweaty and dirty brown butt cheeks. The girl was greeted by the shit stuck all over the inside of Mirko's buttocks, which quickly soiled her cute face and hair in the brown filth, Eri tried to use her small hands to push away the heroine's fat ass, but they only managed to sink into the fat of the buttocks, and her disobedience was punished with a powerful fart. *PPPPPFFFFFFFHHHHHLLLLRRRRRRRRTTTTTTT!!!* The disgusting miasma made Eri cry, but also made her understand that she had no say here, she had to obey if she didn't want to be punished again...and after being digested twice...the pure fear made her stick out her tongue and start licking that black, shit-covered pucker like a good girl.
 
Eri tried her best to clean that dirty anus, but all she managed to do was spread the shit around with her little tongue, however, Mirko enjoyed it, as shown by the farts she casually let out between licks. *PPFFFLLRR* *FFRRTT* PLLOORRPPP* Good Eri-chan, not bad for a newbie, but just licking isn't enough, a TOILET has to SWALLOW. Those words chilled Eri's blood, "a toilet? Oh god no, she didn't mean it..." but yes, Mirko meant exactly what Eri feared, and she proved it shortly after. Opening her anus widely, and holding Eri in place with one hand, Mirko let out a huge chunk of hot shit right into the girl's mouth, forcing her to stretch her jaw painfully at the size, the bones scraping her throat, and the volume of the shit not letting her breathe, what's worse, Eri realized, that shit was her, it was what her body had become after being digested for the second time...and now she was being forced to swallow it.
 
Mirko let out moans and Eri let out cries as she was forced to eat and swallow more and more of the massive shit, the register of poop bulging her throat and going down to her stomach, beginning to inflate it rapidly, making her feel heavy and dizzy. But the nightmare didn't stop there, as the shit entered inside her, Mirko began to push Eri's head harder, deeper between her buttocks... and beginning to enter her hot anal prison again, the girl tried to protest, but it was useless, not only did she not have the strength, but her pleas were muffled by the shit made from her own body inside her mouth.
 
Shit came out of Mirko's ass, entering Eri's body, while Eri's body entered Mirko's ass, ironically putting the shit back into Mirko's body. The poop that wasn't being swallowed completely covered the girl's body, dyeing it a color more brown than Mirko's skin, while it was swallowed once again by that hungry ass, her small body, even swollen with shit, entered without problems, and in a more pleasurable way, stretching the heroine's anus, and slightly stretching her insides, almost imperceptibly, no one would know that Eri was there, no one would know that the poor girl was traped there like a anal toy unless they looked very closely, and if they tried, they would earn a kick from the heroine.
 
As Eri's feet finished entering the dirty tunnel once more, Mirko rubbed herself right on the spot where her new anal toy was located, in the end, that day hadn't been so bad, she now had a new immortal pet in her rectum and a new quirk. Mirko proceeded to call the Hero Association, putting on her best performance of desperation over an attack by a villain with a Quirk that allowed him to eat people. The news covered the incident, lamenting the loss of the girl with such an important Quirk. The Hero Association cancelled the youth patrol program until further notice, and gave Mirko a month's leave for her to recover from the traumatic experience. Her plan had worked out perfectly...although she really didn't like being taken out of action for a month so she could "recover"...but on the plus side, she now had a new permanent anal pet, a buttplug, food, a toilet, and everything else she could think of to make use of poor Eri-chan.
 
No matter how loud she screamed or fought, she couldn't do anything inside the hot, sticky, disgusting tunnel that was Mirko's shit-filled rectum, doomed to be there like a buttplug between the shit that was each of her former bodies, until Mirko decided to let her out only to use her in other horrible ways, sometimes just the two of them, and other times with other heroines who were close friends of Mirko, all enjoying her new permanent toy together. No matter what they did to her, no matter how many times she was turned into shit, one spank on Mirko's big ass was all it took to bring her back and continue those twisted games, Mirko's friends usually begged to let them spank her, like a lewd reset button to bring Eri-chan back, reborn from that juicy, sexy brown ass, covered in shit, and ready to be used in the worst and dirtiest ways once again by the "heroines" of the hero association...
