Kyouka Jirou, a promising young lady with a talent in not only music but general empathy and combat intelligence, was spending her days just like many other girls in the academy. She had always wanted to prosper not only as a musician but also as a hero, doing her best to improve in every regard possible to fulfill her ambitions regarding her future. Sadly, she came to learn that there is only so much that can be done by a lone person. She was not alone entirely, having close ties with her friends in the same class, however she had problems that could not be so easily expressed to many of them. She had strong legs and a very plump, juicy set of ass but basically no upper body muscles or even tits. Her tits looked young, perky and pink. Though that wasn't a bad thing, they felt insufficient compared to her muscular peers with heavy, bouncing jugs. Kyouka never had any issues with her body until she started training to become a hero and learned that her one sided proportions made it difficult for her to be athletic. She could not even walk at a good pace without her super fat buttocks clapping and alerting nearby enemies in any mock combat scenarios. Her leggings would always be worn down or even busted under the pressure and friction of her gorgeous globes of ass and thick, fat thighs rubbing together. She knew that she had to somehow add more muscle to her frame or workout enough for her fat thighs and ass to get slimmer. But she was lost in thought about who could possibly help her.

During one of her usual pondering and empty-headed walks around the school, Kyoka spotted a familiar face doing squats in the middle of the track field. Kyouka always admired Uraraka's confidence and intense desire to always improve. Motivated once more by her friend, Kyoka considered opening up to her about her troubles regarding her fat ass, but she felt too shy. Kyouka could not explain to one of the girls that she made up her mind to either lose her fat ass or build up muscle on her frame, she would be ashamed to even explain something like this one of them. Plus, she felt like her friends had bodies far stronger or balanced than hers, no matter how good they were to her; she felt like she would be judged. Talked about behind her back, shamed or laughed at. However, Kyoka thought it might be fine with one of the boys as her training coach since the boys were always straightforward about this sort of stuff. After some thought, Kyouka finally decided on Deku, since he was always so kind and honest. It also helped that he was dedicated to building up his body to become stronger. With her mind now set on her goal, Kyouka headed to the gym, the clapping of her fat buttcheeks basically announcing her departure to everyone around.

Deku was using the precious free time that he had outside of his studies to workout in the gym. He was spending more time there than anyone else. Deku's body was forged through his intense and relentless effort, most of his body at least since his huge cock was just a natural born gift. Sadly for Deku, that blessing was also one of his greatest burdens, he had always worn crotch guards in class and during his hero duties just to prevent his huge dick from flopping around. Due to often being alone in the gym, Deku felt comfortable enough to go around without wearing his crotch guard, letting the beast roam freely inside or sometimes, peeking outside his shorts. Deku did not know that Kyouka was currently watching him around the corner as he was curling some dumbbells with the tip of his huge dick touching the floor.

Kyouka did not expect Deku to have such a huge cock, nor did she expect to accidentally see it. Plus, even if her eyes were closed, she was sure she would notice the smell of the humongous cock. The smell was filling the entirety of the large gym's air, possessing the

noses of ones who smelt it, making their minds go weak and blurry against this pungent musk. At least, that's how Kyouka felt, it wasn't odd that she didn't hate the smell...right? Kyouka felt that she could not just peep on him after all the nice things he had done for her so far. Kyouka slapped her own puffy cheeks and shook her head from left to right vigorously to muster up some courage before speaking up to draw his attention.

''Oi! Izuku, you sure are working hard, huh?''

Jirou did not draw attention to Izuku's huge cock peeking out of the legs of his shorts. She simply hoped that he would notice it and do something about it, but it seemed like he simply did not care about it as he stood up and started walking towards her with his huge cock leaking sour smelling precum all over his shoes with each step. Jirou could clearly see his huge and meaty cock slapping against his legs as he walked. Izuku spoke calmly and kindly as if all of this was normal.

''Oh, hello there Jirou. I am just warming up so that I can get to doing some serious exercise later today. What brings you here? I am not used to seeing you around the gym.''

Jirou felt like she could just ignore the fact that his huge cock was out there and visible simply because of how kind and calming Izuku was. She smiled, thinking that she chose the correct person to get physical fitness advice from. Jirou spoke with a hopeful smile on her face.

''Well, I wanted to get some help from you regarding my body. I don't really feel fit enough to do all of that athletic stuff when my thighs and butt are so big... I was wondering if you could help me either work some of this fat off or add more muscle to other parts of my figure. Can you help me with any of that? You are basically the only person I can go to, Izuku...''

Jiro could swear that Izuku's smile turned into a predatory grin for a moment after she said that, a look that he didn't have even in the toughest of his fights, but she could not be sure. Izuku spoke after he got even closer to her and started touching her upper body. Jirou's patience was being pushed to her limits, the scent had gotten stronger and so did her urge to mention the giant 'elephant' in the room. But she resisted.

''Wow, not even your forearms or shoulders have any real muscle on them... I would expect you to build up some muscle from just playing music, but you have nothing up here... Even your breasts are a bit...''

Jirou was glad that Izuku was kind enough to not say what he was thinking to her face. She knew that her breasts were absurdly small, especially compared to the size of her incredibly large ass. She was desperate to get some honest opinions regarding her body, so she tried to stop her nervous shaking and she swallowed her pride as she spoke.

''You can just say it as it is, Izuku... I know that my tits are small. I am not expecting you to help me with that, but just help me with my workout...please?''

Izuku had to think for a while but then spoke with a confident smile, though Jirou felt like that confidence was mixed in with some lust and perversion, her thought settled in more when

she realized the already large cock was growing and throbbing a little bit. When Izuku finally responded to her words, his hands were around Jirou's slim waist, slowly sliding down to her super wide childbearing hips.

''I understand you, Jirou. I will make sure that your body is put to work. You will be sweating buckets when I am done with you.''

Izuku's cock seemed to be slowly getting bigger and stiffer, but Jirou was more focused on his words than his monster cock. Finally, someone that was willing to help her! Jirou quickly replied with excitement as she ran to the dressing room to put on her training clothes, though she had her fears regarding her training tights, since her ass had gotten even bigger in the recent weeks.

''Thank you so much, Izuku! I will go get dressed and come back in a jiffy!''

Izuku sat down as he watched Jiro's super fat, soft and bouncy ass jiggle and clap as she jogged her way to the dressing room with utmost hurry. Izuku's dick was getting harder and harder as he imagined putting his cock between those fat buttocks and cumming all over her bare back. Izuku had all the intention to empty his balls using Jirou today, her fat ass and flat chest actually suited Izuku's tastes. For some reason, Izuku felt like Jiro's musical abilities actually helped her when it came to keeping a pleasant tempo with the clapping of her buttocks. However, Izuku's arousal reached a new high when Jirou came back with an unbelievably small crop top and extremely tight fitting tights. Though small, Jirou's tits were incredibly well shaped. They were like large, squishy and perky tear drops, sitting on her chest and begging to be handled. The small crop top was revealing them slightly and giving Jirou a tasty underboob. Izuku couldn't wait to get his hands on these soft tits. Izuku was nearly foaming at the mouth when he saw just how tight fitting Jiro's workout leggings were, he could basically see every detail of her pussy from her cameltoe and her buttocks were individually visible and were still clapping against one another with a greater degree of visibility than ever before. Now the mountains of tasty ass were shining under the material of the tights, they looked tastier than ever. Izuku managed to restrain his urge to tear apart her clothes and fuck her right then and there and listened to her speak instead.

''Well, it has been a while since I wore these tights last time... I may have gained some weight since then... I can go change back if you think they are distracting.''

Izuku was quick to respond in denial, despite not making any effort to hide his gargantuan cock progressively getting bigger and harder resulting in his shorts being stressed beyond measure.

''Ah, it is fine Jirou. Everything is okay. We should just start with some simple stretches... We don't want you injuring yourself, right?''

Jiro responded positively and jogged in her place out of excitement, making her fat buttocks once again clap with a rapid pace and jiggle seductively.

''Yes! I would be delighted with finally getting some progress done even if it is just stretching. But, Izuku, I don't even know how to stretch properly, can you show me how?''

Izuku would be glad to. He walked up to her and held her fat thighs in his rough and strong hands before speaking.

''I am going to lift these up slowly, don't worry about a single thing. I am not going to make you stretch more than what you can handle.''

Jiro could feel a sinister tone in Izuku's voice, combined with his smile getting progressively more evil and his cock getting harder and harder. Despite all these signs, Jiro also felt like Izuku was going out of his way to help her while she did nothing but worry about useless stuff. Choosing to believe in Izuku's good intentions, Jirou nodded her head as she spoke.

''Yeah, thank you for all of this Izuku... I am sorry for making you bother with my heavy thighs when you should be focusing on your own training right now. I am such a burden...''

Izuku was quick to press his face against her neck as he lifted her left leg upwards slowly. He knew that he had to just take advantage of this situation and pump her pussy full of cum before she left this gym. Jirou was freaked out with him pressing his face into her neck but kept quiet, thinking that he was not doing it intentionally. However, she could not understand Izuku pressing his crotch against her ass as he lifted her leg up. Jiro decided to finally speak up, but made sure that she was speaking kindly so as to not accidentally offend him.

''W-well... Izuku... Could you just maybe slow down? A-aw... My leg is already super stretched and... Y-your thing is pressing against my butt. C-can you stop maybe?''

Izuku was smiling even as Jirou complained about the situation, he started humping against her massive ass cheeks as his huge cock grew larger and larger. Izuku spoke with his usual kind voice that did not fit his actions as he lifted Jirou's leg up to a perfectly 180 degree position. He acted like his cock was a separate being from himself, as though he didn't notice what he was doing.

''We are just starting with your stretches, Jirou. I am just making sure to get some stretches in myself. Should I really just stop? Don't you want to make some progress with your training?''

Jirou wanted to keep being kind but her patience was running out, especially how intense the musk and the feel had gotten between her ass cheeks. she replied with a clear message in mind but with a kind and muted voice.

''W-well... I-I would very much like it if you just stopped here, Izuku... I can feel your cock humping against my butt, it is too big to really mistake it for anything else...'' She didn't want to add the fact that the throbbing veins and the layers of foreskin surrounding the wet tip could all be felt against her ass cheeks but suffice to say, this cock couldn't really be mistaken for anything else, it was a being of its own.

Izuku kept his kindness in his voice but his actions and words did not really fit his tone at all as he pulled down his shorts and also tore apart Jiro's tights.

''Too bad, I am feeling horny, Jirou. I can not let that fat ass go without having my way with it. I will still make you sweat a lot, alright? I was not exactly lying to you, Jirou. You are going to get an exercise, just not in the way you thought of before.''

Jirou's ass cheeks and fat pussy mounds jiggled vigorously after finally being freed from the tights. So much so that they even managed to clap and make lewd noises even with the presence of Izuku's huge man meat between them.

'What… is… happening?!' Jirou screamed in her own mind. It was like she had no control over anything including her own body. Izuku was holding her so tightly and strongly around her waist that she couldn't walk away or even stagger although she was standing on one leg. The power Izuku's musk had over her was more than the power she had on herself. This odd but tantalizing smell was filling up her nostrils, clogging her pores, filling into her ass and pussy holes and making them tingle with a weird sensation. Jirou didn't know what that was, it was unlike anything she felt or smelled before. Whatever it was, it was like a potion, a spell… cast to make her mind go weak and let her arousal take the place.

While dribbling and failing to move her body, she tried to resist with her words:

''L-Listen… Izuku…I t-thought you were… g-going to, h-h-help me! This is n-not h-help!!'' Now was the first time Izuku's evil got mixed into her tone.

''Oh trust me Jirou.'' he said. ''I'm doing you the biggest-''

''AAH!!'' she yelled in shock as Izuku suddenly stuck his giant fuck stick between her pussy mounds.

''-favor you can ever think of.'' Izuku finished his sentence with an ominous grin.

'This is bad...so bad!!' Jiro thought. The rough hands that held onto her waist before were now clenching her by her massive ass cheeks as the other one stretched her left leg to its limit. Jirou felt like she was about to split in half. To make matters worse, there was a huge cock grinding against her pussy, trapping her in a different way, leaving her conflicted with her own desires. She knew she had to run away, scream, squirm, do everything in her ability to escape this situation but her hungry pussy was stopping her. The more that monstrous cock rubbed against her clit, the more she felt fulfilled. The deeper Izuku pushed his cock, the more she wanted to embrace it.

Izuku could see Jirou's confliction and wanted to encourage her naughty side while oppressing the other one.

''There you go, look at you grind on my hungry beast, you're a natural slut Jirou!'' He spanked Jirou's ass cheek as hard as he could at the end of his sentence.

''AAAA-AH! W-W-WHAT A-ARE Y..OU..!'' Jirou couldn't even make up her sentence. She just felt so much pain and tingling all throughout her body. Her fat cheeks were still jiggling and clapping from the force, wearing the red hand mark of Izuku like a badge of sluttery.

''Your nasty pussy juices are starting to coat my mighty cock, you like this don't you Jirou?''

'No!!' She said under her breath but… did she? Or was it just her body's reaction to the intensity of this situation, it was just because of shock… even Jirou herself didn't know anymore. She knew that Izuku was right though, when she looked down, she saw that her sweet juices had glazed her fat mounds, thighs and Izuku's throbbing cock. She was even dripping squirt and creating the tiniest pool on the gym floor. The mark on her ass cheek burned, did it burn bad, did it burn good… she didn't know. Her mind had been fogged up by the tantalizing musk at this point.

Jirou's confusion was stirring up Izuku's sex drive. He could feel her losing her balance and shaking under his arms, this must be all new to her, he thought. Izuku believed that he could turn her into his personal breeding bitch. The slut was already starting to dribble cum and coat his cock in that sweet pussy juice. She was in the perfect state to take Izuku's cock. His cock couldn't wait any longer too, now that it was erect, it was as hard as a rock and standing tall, almost at the height of a person. The base was sliding between the pussy mounds and being embraced by them while the nasty tip was almost going to reach Jirou's face. Not being able to see Izuku, Jirou almost forgot that this was a part of him and not a mighty being by itself. There was no way this cock was going to fit inside of her although… there was a small, kinky side of her that wanted to try. 'It's probably the stench… that's why I'm thinking of things like this… right?' Jirou thought while her eyes were watering with the incredibly pungent smell. It was especially strong on the tip, where her face was close to. A thick, yellowish paste could be seen between Izuku's foreskin folds. 'Is that what they call… dick cheese?' she asked herself. She had heard her girl friends talk about it and got disgusted with the image of it but she didn't think anyone she knew had them… especially Izuku…

Just as she was escaping to her thoughts to avoid her situation, Izuku's cock thrusted in her as a stern reminder. Izuku had to go back and position his massive donkey cock with both of his hands just to stick in Jirou, but the effort paid off as soon as he heard Jirou's helpless, confused and aroused screams.

''MHMM-MMH!..! IT'S S-SO-h… b-biig!...''

Jirou jumped in her place as soon as she realized what she had just said. She sounded like she wanted this ugly, stinky cock, what was going on with her!

It was almost like the cock was taking over her. First she was captured by its smell and now her insides were being punished by it. Jirou thought Izuku went all in and stuffed his massive cock in her completely, but when she looked down and saw that not even the half of it was in, an instant fear struck her body. How was she going to survive this?

Jirou started to jump with her one leg and somehow get away from Izuku's captivation. She noticed that she was slowly giving in to him and her nasty desires. She had to run away for the last time before she became Izuku's total breeding slave. No matter how much she jumped, squirmed and whimpered in her place, Izuku didn't let go. In fact, he saw this as a dash of 'spice' to their love making.

Jirou couldn't move at all, Izuku's hands were almost pinned to her slim waist. He was skillfully using them to direct and ride Jirou however he wanted. It had become too late for Jirou. She was beginning to give into her senses and the demands of her hungry pussy. Though she didn't want to admit it, this was the best her pussy had ever felt. Izuku's dominance machine was filling her completely and pushing her walls to their limit, every

sweet pleasure spot inside her were being penetrated at the same time. Her pussy walls were clenching around the cock and embracing it as much as they could. Now, Izuku had pushed a little more than half of his cock in. Jirou was already fulfilled and pushed to her limit, she was both afraid and also excited for what was to come.

Her tiny tits were jiggling and bouncing in her place. Her pink nipples had gotten so erect that they made her small crop top ride up, revealing themselves adorably under the short cloth. They were so sensitive that even the air around them caused them to flinch and hurt whenever Jirou's body moved with the thrusts. Jirou didn't know there was a kind of pain that could feel good… but this was it.

At the back, Izuku was fucking Jirou as hard as he could without breaking her. He had to hold back so that he could use his full strength to make her his bitch later. He felt like a wild monster that was handling a dainty flower. At any point, Izuku felt like she could split in half. Izuku could see this from how far stretched her tiny hole had become. At first, it was shyly gaping in and out, blinking and Izuku. But now, it was getting wrapped around his cock, getting stretched to the point where her pussy was about to become one with her pink asshole. Izuku didn't expect Jirou's pussy to be this hungry, it was dripping with squirt and cum everywhere too. Every time Izuku pulled his cock out a bit to stick it back in, he could see white, bubbly cum and squirt pool between his throbbing, purple veins. The smegma between his foreskin folds were unfurling inside Jirou's pussy and getting rewarded with her tasty pussy juices. Izuku felt like he was in his own personal heaven. Now, he needed to secure this heaven by asserting his dominance over her. So he pushed his stinky cock, all the way in this time, and started being rough with Jirou.

''OOOOHHHHHH G-GOOOOD!!!!!'' Jirou screamed at the top of her lungs as Izuku pushed his cock to its base. Jirou could feel his heavy, low hanging balls hit against the wet mounds of her pussy and make repetitive sounds. As well as the loud clap of her ass cheeks and her short, pain and pleasure filled moans. This was like the song of her downfall. She began feeling the rhythm of Izuku's thrusts all over her body. It was captivating, almost manipulating… she was getting sucked into pleasure and being drowned in it. As she was getting lost in these sounds, she was pulled out by Izuku's devious, calm voice. He still sounded the same way he did before all of this.

''You have no idea how much your nasty pussy is gripping on my dominant cock, Jirou. What happened to all the times you complained? You seem to like it now, don't you, you bitch!''

''AAAHHH!!!!'' Izuku slapped Jirou's fat cheeks with his strong hands. A new hand mark was added to her soft skin even before the previous one disappeared. Jirou's jiggly cheeks were flushed red, just like her cheeks, tits and lips. The adrenaline was too much for poor Jirou, she felt like she was about to faint.

''You said you came here to work on those tiny tits of yours-'' ''I d-didn't say th-at!!''

''Who gave you permission to speak?!''

*SLAP*

Once again, Jirou was punished and startled by the huge hand spanking her soft cheeks. This time, she felt like she got used to it or maybe… even… liked it?

The adrenaline rush was keeping her body awake under all this crushing penetration and she was craving more and more of it every time. Her lower body was sexily bouncing and shaking without her noticing, it was inviting another spank.

''Look at you, you are already asking for more! You are such a dirty slut aren't you?!''

*SLAP*

Izuku had no mercy in his slaps, they were almost hard enough to draw blood from Jirou's fat cheeks. They seemed to be enjoying it though, jiggling around enthusiastically.

Izuku couldn't hold himself back anymore, he could feel the warm, thick batch of swimmers swim up to the tip of his cock. His tip was throbbing against the force of Jirou's clenching walls and his whole body was shaking with excitement. He decided to give his last pushes into Jirou and take the first biggest step of owning her completely.

He tightened his grip against Jirou's leg and wrapped the other arm around her waist. The grip was so strong that Izuku's hands had formed a red ring around Jirou's leg. But she was too far gone in pleasure to notice. The only feeling she had was on her tits, pussy and fat cheeks. She believed that her only reason for being was for pleasure.

Izuku pulled himself back and without any warnings, thrusted into Jirou's pussy as hard as he could.

''AAAAHHH!!'' Jirou felt an immediate rush of arousal, she had been cumming non stop all this time but this one push was enough to get her pleasure juices going again.

Jirou's pussy walls tightened and began throbbing with Izuku's cock. Izuku, pleased with the reaction he got, prepared himself for another thrust.

''OOOOOOHHHHHHHHHHH!! I'M CUMMMIIIIING!! I'M CUMMMMIING LIKE A DIRTY SLUUUUUTTT!! OOHHHH!!''

White, stinky baby batter started gushing into Jirou's womb. In no time, her womb was filled to the brim completely, owned by and coated with Izuku's swimmers. They were so thick and stinky that Jirou could feel the stench coming from her womb and deep inside her pussy.

She didn't know if it was the overwhelming pleasure or the pungent, eye burning smell; but either way, she felt another wave of pleasure in her crotch, leading to multiple orgasms. The smell she despised once she entered the room was now the smell that gave her bitch pussy orgasms, the one she had become addicted to. With a dazed look, she opened her mouth and breathed in the smell from her nostrils, as hard as she could. She wanted to taste the scent, to feel like her tongue was swirling around the base and tip of that amazing cock.

Just as she rolled her tongue out from her mouth and made her lips into a sultry 'o' position, the cum that had been building up inside her walls and womb finally gushed out. A fountain

of cum started gushing and spilling on her thighs and juicy ass melons. Jirou couldn't believe that Izuku could cum that much, and from the warm spill she felt on her left cheek, he was still cumming! He marked every nook and cranny of Jirou's insides with his dominant stench and swimmers, leaving no place for another man. He filled her baby making box to the brim and still kept on marking her on her ass. As she fell to her knees after the huge load, she caught a glimpse of the cum spilling from her, the small puddle she started forming twenty minutes ago had turned into a huge, sticky puddle of cum and squirt. With shame and arousal, she fell to her knees.

Jirou was both impressed and incredibly turned on. She was now laying down on the gym floor, her shirt covered in cum and sweat... She was too far gone in pleasure to think how she came to be in that situation, or her fat cheeks, or anything else other than Izuku and his mighty cock… She just felt fulfilled in knowing that she belonged to him. Everything proved it, from the markings on her ass to the trails of cum in her pussy walls.

''!!'' Jirou came to her senses when she felt Izuku's manly hands on her cheeks. He was spreading them and kneading and playing with them as if she were a toy. Jirou could feel the sticky cum between her cheeks form long, thick lines as Izuku tried to separate them.

Though it had been some time since he came, she could still feel the warmth of his cum. She got embarrassed and buried her face into her arms. Even then, she couldn't escape the realization of her sluttery. The stench of her cum covered shirt hit her hard like Izuku's hand on her ass cheeks, and reminded her of her one and only purpose: pleasure.

''I told you didn't I… you would thank me. You don't believe that you are a naughty breeding slave. But I do… I know.''

His hands had started to get rougher and rougher. Jirou's cheeks were getting pinched and kneaded, she felt as if she was getting tenderized. The parts Izuku had previously hit hurt the most but somehow, that made them feel the best.

''Tell me you whore, how does it feel? To be dominated by your classmate's stinky cock, to like the putrid stench that disgusts others, to enjoy being dominated, bred and used as a fuck toy, tell me!''

*SLAP*

His spanks were almost like exclamation marks at the end of his sentences at this point, he would spank hard and make his question heard loud and clear.

Jirou's ass cheeks rippled under the heavy hand, the waves of force were travelling through her soft flesh just like the waves of pleasure did. She couldn't dare to raise her head from the arms she was burying it in and she just nervously began thinking.

'What should I say, I shouldn't say that I like it, right? I should be angry, I should be… yelling and stomping my feet! But I am not, I like it… Why… Just why do I like it? I don't know what to say anymore, I don't know what to feel!'

''I said, tell me!!''

''AAAAAHHHHH I'M SORRY! S-SORRY MASTER! I-IT FEELS GOOD! IT FEELS SOO

GOOOOD!'' Jirou, who had been hiding quietly between her arms, spoke like a parrot with the help of Izuku's merciless slap. She didn't even know which cheek it was on at this point, as both of her ass cheeks were burning in pain and tingling. She didn't know what to focus on, her pain or the fact that she said all of those things! She didn't even think for a second, she just rambled and outed her submission to Izuku, and 'master'?! Jirou's face was almost as red as her ass cheeks, she buried herself deep into her arms and accepted her faith, her faith as a mindless breeding slut, a pet who serves the sexual needs of her mighty master. Her identity had been washed away along with his common sense and ability to think, all that was left was her instincts.

''Good, good. Good job you dirty girl, you spoke the truth.'' Now, Izuku began massaging the ass cheeks instead of hurting them, it was almost like he was training her into becoming more submissive. Another thing she needed training for was being Izuku's bitch, Izuku was just about to work on that.

He looked down at his crotch and saw that his cock got hard again, he had a raging boner. The sweet juices of Jirou seemed to be good for the cock, although it just came gallons on cum, it seemed ready to splurt another batch.

''Get on your knees and bend over.'' Izuku demanded. Jirou didn't think for a moment and obeyed her master. When she got on her knees she realized that her shirt was completely soaked and dirty, she felt guilty for looking like this while serving her master, so she timidly turned her head around and asked:

''C-Can I… take my shirt off?''

Izuku smiled, she was finally getting the hang of the dirty talk and asking for permission. ''Yes, yes you can my slut.''

Jirou slowly took her shirt off and revealed her gorgeous, young tits. The cum went through the shirt and made a gorgeous glaze on her tits. Izuku wondered how nice it would feel to tease them.

Just as Jirou was about to throw her shirt off, Izuku had a devious idea. ''Wait.''

Jirou looked up curiously.

''Put it in your mouth and bring it to me.''

''?!'' Jirou was confused, what did that have to do with anything?

''I said what I said.''

Jirou was nervous, she had definitely done more shameful things with Izuku today, but… this felt like another low point.

Though, she did want to know the taste of Izuku's smelly cum. The cum that was so strong that it filled up the entire gym, the cum that could be the reason behind all of her manipulation…

She had her mind set, she was going to do it. She put the dirty cloth in her mouth and slowly walked towards Izuku. Immediately, she was struck with the odd, strong taste. It was hitting all of her taste buds at once and making her knees go weak. Who knew that after carrying all that ass for so long, cum would be the thing that made them go weak…

She started sucking onto the cloth to get more of that taste, it was so addicting, she couldn't get enough of it! She even walked slower to have more taste.

She couldn't hold her arousal in and let out a small burst of cum dribble from her pussy, she felt pathetic. She was cumming on the taste of Izuku alone! But how could she stop herself, it was just so tantalizing…

After bringing the cloth, Izuku nodded gently and told her that he will be giving her a reward soon. Jirou excitedly got back to her position and bent over. She had lost all of her shame at this point.

Izuku's cock was violently throbbing at the sight of the spread ass cheeks. He didn't waste any more second and put his large cock between Jirou's fat melons. The juicy ass cheeks instantly embraced them and rippled around the meaty cock. Izuku could even feel Jirou's blooming asshole gaping in and out, gripping onto the base of his man meat.

Jirou was just as excited and impatient as her ass made her to be. She was licking the corners of her mouth to eat the leftover cum from the shirt and also imagining her cheeks getting covered with that same delicious cum. She wanted to please her master in the best way she could, so she raised her ass and squeezed her ass muscles to give a good grip to Izuku. She began moving and skillfully jerking the cock off, going with the rhythm of Izuku's slow thrusts.

''Oh...that's my bitch, keep going…'' Izuku's cock was enjoying Jirou's warm embrace. The muscle and fat she had gained over the time kept adding to her ass cheeks, making them the perfect candidate for fucking thoroughly. Plus, her thighs had to get stronger to carry those huge mountains, so Jirou acquired thick, soft and silky smooth thighs. It felt amazing to stick the base between those thighs. To make the grip tighter, Izuku grabbed Jirou by her legs and crossed them.

''O-Oh!!'' Jirou moaned lightly in surprise, she didn't realize it until now but she must have felt like a feather to Izuku. He crossed those legs with no warning and effort. His masculinity stirred up Jirou's sex drive.

Izuku's cock was now completely buried between Jirou's thighs and ass cheeks. Even though she had the fattest cheeks he had seen, they weren't enough to fully cover the girth of Izuku's fuck stick.

Izuku grabbed Jirou by her waist and moved her to his liking. The squeaky floor was making noises and joining the noises of Jirou's clapping as cheeks. Jirou's knees were rubbing on the floor and getting rashes, but she was too drowned in pleasure to notice. Plus, pain that's inflicted by her master has become pleasure, she accepted and embraced it at all costs.

''How did you get these cheeks to be this fat Jirou? Have you been whoring yourself before me, huh?''

Jirou nervously answered, she would never do that to her owner!

''No, never! Y-you are the only ones who can fuck them and breed them as much as you like!''

Izuku smiled. ''Good, good… you know your place.''

Gaining even more confidence with Jirou's words, Izuku started pushing his cock harder. The tip of his cock was travelling between the cheeks and Jirou's smooth back. The thought of his tip slapping against that back and spurting cum everywhere made him go crazy, he had to make it into reality. His tip was unfurling and covering everywhere it touched with thick, smelly, yellow dick cheese. It was leaving thick trails and signs of his ownership all over Jirou's back and ass cheeks. Jirou's nose felt the creamy delight on her back and started moving it like an excited bitch. The smell was like a concentrated version of Izuku's cum, Jirou's nose was celebrating.

Izuku started squeezing and spanking the ass cheeks to increase the tightness, plus, the more his bitch yelled in pain, the closer he got to his orgasm.

''AAH!!'' Jirou moaned and yelled with the hard spank. She figured he was finally about to cum! She moved along with his thrusts and tried her best to behave, but her tingly pussy was making it difficult.

''AAAHH! Y-YESS..!!'' Another spank landed on her juicy, fat melons.

Finally, Izuku started releasing his thick, warm cum. He glazed the fat cheeks as if they were two, soft donuts, he filled the crack of Jirou and made it overfill to her thighs and all the way down to her legs. He aimed his tip at the back of Jirou and let his baby batter roam all over the place. Jirou was being marked all over.

Meanwhile, she was squirming and shaking in cum, releasing her sweet juices all over herself. Though she tried to be stable and allow her master to coat her, she was still shaking from immense satisfaction.

Izuku's cock was still erect, if not more erect than ever. He was ready to totally own Jirou and make her his personal breeding slave. It was time.

Izuku was silently and ominously gazing at her, so much so that Jirou turned to him and asked:

''D-Did I do anything w-wrong?'' She was more scared of his predatory eyes than the answer he would give.

Suddenly, he grabbed her by her legs and brought them up to her head, revealing her naughty, wet pussy.

''I-AAAHHH..!!'' Jirou was about to apologize for what she thought was a mistake but she immediately got silenced by the fat cock thrusted into her. Thanks to her pussy juices lubing her pussy walls beforehand, half of Izuku's cock slid right in. Izuku's eyes were almost burning marks onto Jirou, they were gazing over her body with hunger, almost lighting a green shine ominously. Jirou felt honored to be desired by such a manly man like Izuku, she was desiring him too, more than she could admit. Her whole body was burning with desire, so much so that the hand marks on her ass had become redder and bright with the flush of adrenaline filled blood. Her cum covered ass cheeks were slapping onto the ground and making wet noises, Jirou could feel her asshole gape in and out with desire. Everything from her erect nipples to the constant tingling in her pussy walls, she was ready to be fucked and bred thoroughly.

Izuku began thrusting roughly into Jirou's fat pussy. Knowing she was now under his control and already been fucked once, Izuku showed no mercy. He could feel his tip push against her womb and stretch her insides to the limit but he wouldn't stop. He would slowly make sure that there wasn't a part of his long cock, that wasn't getting embraced by Jirou's tight walls.

Jirou started hyperventilating to keep herself calm, if not, she would scream in agony and pleasure. This was the most stimulation she ever had in her life, her body didn't know how to react, she didn't know how it was still intact. She could see the girthy, meathy behemoth enter her tight pussy and reach up to her stomach. She could even see the clear outline of Izuku's cock from her stretched out stomach. Jirou was dumbfounded by the sight, at one point, her mind went blank and she felt like she was either fainting or reaching another state of being… even she couldn't believe these were all because of one cock.

Seeing the large bump stick out from Jirou's stomach was turning Izuku to a pussy hungry beast. There was nothing like power for a dominant man, it was the source of and power of all lust, the power of being able to break a bitch's mind and at this point, body with his cock, made Izuku absolutely crazy. He had just been able to get all of his cock into Jirou but he couldn't wait another second before increasing his speed.

''OH GOD….OOH.. GOOOD!!'' Jirou started screaming and begging to God. Breathing didn't work anymore, this much stimulation was making her lightheaded. Every other part of her body was starting to go numb, all of her senses and stimulation was focused on one place: her pussy. She could feel the previous cum covered places gush inside of her with the fast thrusts, she stopped counting her orgasms at this point, she was being engulfed by Izuku's cock and getting trapped in constant pleasure.

Both Izuku and Jirou were ready to burst into cum, their bodies were impatiently quivering and squirming in their place. The floor was covered in Jirou's squirt and Izuku's previous cum. So much so that whenever Izuku thrusted, Jirou's cum covered back was sliding on the gym floor. Her ass was sore and throbbing with pain, her nipples and small tits had swollen to twice their size, they were just as bright as the rest of Jirou's worn out body. The rhythmic slaps and wet noises of skin, ass and genitals clapping against each other were echoing through the large gym. They both couldn't take it anymore.

Izuku started pulling his cock out to do his last thrusts. His behemoth was so long and massive that it took a couple of seconds to pull out, he stopped at the tip and took long breath.

''OOOOOOOHHHHHHHHHHHH!!!!!...!!'' Jirou's long wail filled the gym as Izuku pushed his cock back in. He pulled it out once more and pushed it in again.

''OOOOOOOHHHHHH… I… CAN'T TAKE IT ANYMOREEEE AHHH!!'' Izuku's veins were

purple and grotesque, he too, couldn't take it any longer. So he pushed his cock in last time.

''OOOOOOOOOOOOOOOOOOOHHHHHH!!!!! I'M CUMMIIIING DEKU!!!! FILL MY BABY MAKING BOX WITH YOUR THIICK SWIMMERS!! YESSS OHHH..!!!''

Finally, a white stream of cum started flowing in and filling Jirou's womb. Instead of pulling his cock out, Izuku let it fill the womb to its breaking point and make sure Jirou was getting all of his swimmers.

''OH! OH GOD! IT'S GROWING, YOUR SWIMMERS ARE FILLING MY WOMB, AAH!!' Jirou

yelled in excitement and awe as her stomach got larger and larger with the thick cum. After a minute of Izuku cumming, she looked like a pregnant woman, she felt all of the cum sloshing inside her and marking her womb.

Izuku finally pulled his cock out and let the remaining cum gush out from Jirou's pussy. It was a mixture of her sweet pleasure juice and Izuku's smelly cum. It was the proof of Izuku's ownership along with his marks and his invading swimmers.

Izuku finally achieved his goal.

He made Kyouka Jirou his breeding bitch.
