Life wasn't fair was a phrase a lot of people said when something wasn't going their way. Not a single day passed in which someone somewhere in the world wasn't saying that, but they were almost all wrong. Life wasn't unfair—it was simply bad at anticipating how it should be fair. And that Saturday morning twelve years old Katsuki had declared it with all his youthful conviction.
"Do I really have to go?!"
The boy had whined after his mom had told him he would spend the day, the entire day and night at his uncle's place. She clearly didn't understand a boy his age had better things to do with his time, like playing videogames all day long and browsing the internet for funny pictures to share with his friends.
Although he wasn't actually his blood uncle, his mom and uncle were childhood friends and practically grew up together, always looking out for each other. In fact, his uncle was his mom's best man, and when his father died, his uncle became the only father figure in his life. But that didn't mean he didn't like being with his uncle.
His uncle Izuku didn't own a computer, or even Wi-Fi for him to use his laptop. In fact, Katsuki wasn't even allowed to use his phone too much. "Kids those days need more activities than looking at a phone" his uncle would always say, as if he was so smart and knew what the youth wanted.
Of course, the idea was a terrible one, as any adult's ideas are to kids, but what was worse was the fact he couldn't do anything about it. Not only the man was completely out of touch with what kids liked, but he was also a pervert.
Katsuki was more than aware about it, given how every time he visited his uncle's house, he would undress the boy with his eyes, smack his ass as he walked by, or get him to do things like laying on his belly so he could massage his back.
And not only that, but uncle Izuku had two friends who were just like him, and would tell Katsuki things like how cute and handsome he was, how much they wished they were his age again, asking if he already had a boyfriend or if he ever kissed someone, making him sit on their laps and make him pick up stuff they purposely dropped so the boy would have to bend over.
Katsuki had tried to tell his mom about this, about how those perverted losers only wanted to do all kinds of nasty stuff to a poor innocent boy like him, but she would just reply. "Your uncle is just a single man trying to be a good father figure for you. You should be more accommodating to him. He will enjoy having you around more of what you could imagine"
So, Katsuki would be stuck with those perverts until the end of the day. And it wouldn't have been that bad if not for the fact he had planned to play online with his friends. It wasn't like his mom would let him play anyway, she was always going on and on about how he should get off the computer and get some fresh air, but still, that plan was better than hanging out with the old farts. But that was life: unfair, but not in the way people think.
It was a sunny day, as almost every day of summer was, and there was no need to get a coat. Katsuki's mom drove the car along the highway, and after a good forty minutes, they finally arrived to the house where his uncle lived. It was an old one- story house with a white facade. It was a nice place, with a nicely kept front lawn and a back yard large enough to play around.
As the pair exited the car and approached the front door, Katsuki could feel the sweat starting to gather on his body. Summer was the worst time of the year, and not only because it was the hottest. Summer meant he had to wear regular t-shirts and shorts.
He didn't like shorts as they conflicted with his style. He liked baggy pants and long loose t-shits and hoodies even if his mom said those clothes looked ugly and made him look like a hobo. He tried to explain to her about streetwear and why it was so cool but she wasn't having any of it.
"Now, be a good boy, okay?" his mother said, patting him in the head as they reached the porch.
"I'll try" he gave a defeated sigh.
She smiled and knocked on the door. As they waited, Katsuki could already feel his heartbeat faster and his cheeks redden. The thought of spending a whole day with his uncle, who was a huge pervert, and his pervert friends, was making him want to go back home even if he had to walk for hours.
The door opened and Katsuki saw his uncle Izuku. The boy always though he looked like the typical image of a fun uncle from a tv show: an man wearing a flannel shirt and jeans, his hair green and his face sporting a light beard. If only looks could be deceiving, because while the man's face was the definition of warm and friendly, his intentions were anything but that. "Hey Kacchan!. So happy to see you" Izuku said, extending his arms.
The boy tried to hug him, but his uncle had a different idea. He wrapped his arms around him and squeezed him tight against his chest, and to the boy's surprise, he planted a kiss on the top of his head. That wasn't so bad, at least he didn't grope him in front of his mom.
"Hi, uncle" the boy replied, pulling away from the man's grip.
"I'm glad you came" he said.
"I'm glad too. At least, I guess..." the boy looked away.
"Aw, come on, little buddy" his uncle put his hand on his shoulder, giving him a firm squeeze. "You know your uncle is always happy to have you around, right?"
"Yeah, yeah" Katsuki waved him off.
Izuku took a good look at his nephew, whom he had not seen in about a month. The boy was growing fast, but he was still an absolute beauty. Katsuki had inherited the best qualities of his mother Mitsuki: the same red eyes, the same cute face, the same pink lips and the same ash-blonde hair. The only thing the kid had gotten from his father was the shape of his hair.
Other than that, his skin was still smooth as a babies, without a trace of hair anywhere except for his head. The boy was wearing a black shirt and caqui shorts that fit perfectly on his petite body. Even with his clothes on, the man could tell he had a beautiful figure, and the fact his legs were exposed, made his blood boil.
The man was sure the boy had the most perfect ass in the world. He could only imagine how good it must look naked, his small bubble butt sticking out and waiting to be touched. If things went well, he would be able to see it as often as he wanted from now on, he thought.
"Katsuki, be a good boy and give your uncle Izuku a kiss" his mother said, nudging him gently.
"What?" the boy's eyes widened.
"Go ahead. Show him how much you missed him"
Katsuki didn't wanted to do it. Kissing his uncle wasn't his idea of a fun day, and besides, the man had a weird grin on his face. Katsuki whimpered and walked towards his uncle. He stood in front of him, and the man got on his knees so the two were eye to eye.
The boy leaned forward and planted a kiss on the man's cheek. The man's beard tickled his skin, and the sensation of it made him shiver. He pulled away, and the old man ruffled his hair, making the young boy protest at having his hair being messed up.
"I missed you" the boy lied, forcing a smile.
"Thank you, Kacchan" Izuku grinned, showing his grin.
"I've got to go now. See you tomorrow, son" his mom said, and after kissing his forehead, she walked back to her car.
As the engine roared and the vehicle started to move, Katsuki sighed. He didn't like his mom driving off and leaving him behind, but the thought of spending the entire day with his pervert uncle and his pervert friends was even worse.
"Now, I've got some lemonade ready for you" the man said. "We will have fun today! I'm going to fire up the backyard barbecue and cook some nice steaks. My friends Shouto and Eijirou are coming over to hang out and watch the fight later."
Katsuki sighed again. Of course, those two were going to be there. It was never a peaceful day with the three of them. They would stare at him like hungry dogs and make him feel like a walking piece of meat. But his mom had told him he should be nice, so he would have to go with the flow for once.
He thought about what she had said. About how one day his uncle was alone and just wanted his paternal figure. The thought gave him a sting of pain he could not think possible given how he felt about him. His uncle was a perverted weirdo, but he was still family, and deep down, the boy didn't wanted him to be sad.
"Let's go inside, want to help me set the table, Kacchan?" the man asked.
"Yeah, sure" Katsuki said, shrugging.
As the boy followed his uncle, his mind wandered back to his friends and the game they were supposed to play that day. He wondered what they would think when they logged on and saw he wasn't around. Would they wait for him? Or would they just give up and level up leaving him behind? Either way, it was a shame. It was one of those rare occasions in which he could log on.
The backyard was as nice as always, and Katsuki thought that if anything his uncle knew how to keep the place in a nice state. They had a round glass table and a big grill, and the backyard was large enough to run around or play ball. There was a hammock near the garden and the boy remembered how good it felt to sleep on it, letting the breeze gently sway him as the warm sun caressed his skin.
"So, here we go" the man said, serving Katsuki a large glass of lemonade.
The boy took a sip and felt the refreshing liquid go down his throat. The drink was cold and had a slightly sour taste. He took a seat at the table, and the old man sat in front of him.
"You've gotten taller" his uncle pointed out. "But you're still such a cutie"
Katsuki looked away and took another sip.
"Are you excited for summer vacation?" the man asked.
"I guess" the boy replied.
"Why is that? Don't you want to hang out with your friends and play games and watch movies?"
"That's not a problem. Mom is always nagging me, because she doesn't understand the things I like. She even wants to sign me up to some boy scouts thing!"
"Maybe you should give it a try. Fresh air and sun. You'll get a nice tan. And then you'll be even cuter" the man laughed; his voice rough.
"Can we not talk about how I look?" the boy's cheeks reddened.
"Sorry, Kacchan. Your uncle just wants to chat."
They continued setting everything up, and Izuku even allowed Katsuki to lit up the charcoal, which the boy enjoyed, feeling like a man of the house for a minute. Maybe the day wouldn't be so bad after all.
Then his uncle got up from the chair where he had been sitting and walked to the shack at the end of the backyard, where Katsuki knew he kept his gardening tools. He came back with a blue box and what looked like an air pump. Then as Katsuki watched from the other side of the yard, Izuku took out a small inflatable pool from the box and began to fill it up.
"What is that?" the boy asked, confused.
"What's what?" the old man pretended not to know.
"What is that thing? What are you doing with it?"
"Oh, this? This is an inflatable pool, Kacchan" the man explained. "It's not big, but I think it'll do for today. Besides it is just for you"
"For me?" Katsuki raised an eyebrow.
"Yes. I thought you could use some fresh water on such a hot day"
Katsuki shrugged and kept watching. The pool was indeed small, and Katsuki thought he would barely be able to splash inside, let alone actually "swim". It had a pattern of colorful balls printed all over it and he could tell it was meant for a kid younger than him. Katsuki was about to protest when he saw his uncle start filling the pool with a garden hose.
"Hey, that is really small" the boy said, pointing.
"It's enough. Like I said it is just for you to cool off, and maybe even splash around" the man said.
"I'm not a baby. I'm twelve, uncle. You should know."
"Oh, come on, don't be like that. It'll be fun. I even bought you a swimsuit!"
The boy looked at the pool, then at his uncle, those words echoing in his mind. The weirdo had bought him a swimsuit? A new one? Why didn't he just ask his mom to bring his swimming trunks? Then, as if on cue, Katsuki knew the answer to his question.
It was because his uncle was a perverted grown up and wanted him to wear a brand new bathing suit he probably had picked out himself. And not just any bathing suit. The man was an absolute creep, so he had probably bought the most ridiculous and embarrassing thing he could find.
"Uncle, please, don't do this" the boy begged.
"Don't do what, Kacchan?" the man looked confused.
"You know what. Don't make me wear something...embarrassing"
"You'll look great! I bought it for you, and I'm sure you will look adorable on it"
"Please, no..."
"And you'll be nice and cool. It's going to be a great day! So please go inside and get changed. I left the swimsuit on my bed so you can change"
Katsuki was about to protest again when he heard the doorbell, and he knew it was Shouto and Eijirou, uncle's friends. Izuku grinned and spoke to his nephew as he walked towards the house.
"Oh, they are here. You just go change so you can splash around while I cook, and we talk boring adult people stuff"
Izuku laughed like he had said the funniest thing in the world, and soon Katsuki was alone in the backyard. The boy's stomach churned, and he could feel the lump forming in his throat. He was going to have to walk into his uncle's bedroom and change into the swimsuit he had bought for him. He remembered again his mom's words. Be accommodating, she had said. He could try, at least. With that in his mind, the boy got up and started walking towards the house.
Katsuki reached his uncle's bedroom and looked around, noticing a small red bag on the bed. It was that type that was made of paper and had two shoelaces for straps. But the first thing Katsuki noticed was how small it was. He slowly opened it and pulled out what was inside. His eyes opened wide, and his face turned red as a ripe tomato as he held the tiny bits of fabric between his fingertips. Not even in his worst nightmares had he expected something like this.
It was a two-piece swimsuit, a bikini. A micro bikini. A microscopic bikini. It was pink and was so small Katsuki couldn't help thinking of three Dorito chip sized triangles of shiny pink fabric held by dental floss. It was so revealing he couldn't imagine this thing could even exist. Then he saw the printed receipt in the bottom of the bag and the price he saw there almost made him fall backwards. $150 for a tiny pink bikini? For him? He was a boy, why would he need a two-piece bikini? Why would he spend so much money on something so insane?!
Katsuki was about to head out of the room and leave. He would walk out no matter what his uncle thought. He would walk home and then tell his mom about how uncle had gone mad, and they needed to put him in an insane asylum where he wouldn't be able to do things like this. But then his mom's words echoed in his head again.
Be accommodating
He is just alone and wants company.
She had told him, and she would be very mad if he just went away and didn't do what his uncle had asked him. He had to stay there and endure it, for man's sake. Even if that meant putting on the most revealing, tiny and expensive bikini he had ever seen. Also, he thought about the price.
His uncle had spent so much on that thing, it would be extra ungrateful to at least not try it on, and Katsuki wasn't an ungrateful brat. His uncle always bought him the birthday and Christmas presents he wanted, and refusing this one would be wrong. Very wrong. Finally, he couldn't help but feel something strange deep within him as he looked at the skimpy thing between his fingers. Something he couldn't describe. Like it wanted to be worn by him.
Katsuki whimpered and began to undress. He took off his shoes and white socks, his t-shirt and then slid down his shorts. The boy's body was thin and lovely, with smooth skin and just the right amount of baby fat on his hips, thighs and butt. His legs were silken and hairless, and his armpits were bare. His belly and chest were also free of hair, and his pink nipples stood out beautifully, large and puffy.
His penis was still tucked away inside his underwear and Katsuki felt it throb as he stared at the skimpy, tiny bikini. It was so small and tight, and he knew he was going to have a hard time putting it on, especially the part that was meant for his crotch. The boy gulped and slid down his briefs.
Katsuki's member was soft and small, cute with smooth looking balls. There was no trace yet of any pubic hair, and his entire lower body was a smooth surface without a single hair on it. His penis was the cutest thing, with a cute tip and pinkish color. As Katsuki looked at his boy bits, the boy noticed something weird.
There was a tiny bit of wetness at the tip of his cock, a tiny drop of sticky liquid. It was something he had seen before when he accidentally looked at lewd pictures on the internet, and the boys in those photos were always doing things that made their penises drip, like touching and rubbing and licking and sucking. He didn't know why, but his cock was dripping wet as well now.
The boy ignored that and started putting on the tiny bikini. The top was the easier part, and after sliding the dental floss up his smooth arms, the triangular bits of fabric were covering his nipples, barely. He still felt weird wearing a bikini top, but he still put it on.
Next came the bottom. He slid the dental floss between his legs, and his cock and balls were barely covered, with the sides of his balls peeking out. Then he pulled the dental floss up and between his ass cheeks and adjusted the stringy material until it fit. He knew that from behind he was completely naked, and anyone looking could see his little hole if he were to bend over. But he wouldn't bend over no matter what, he promised himself. But even he could see that self- promise starting to crack as soon as he finished saying it.
Finally, the boy looked at the mirror in his uncle's wall and his heart skipped a beat. The bikini was a perfect fit, and he looked absolutely stunning. He stood there, eyes opened wide at what he was seeing. He had seen many pretty boys when he looked at lewd stuff on the internet at night, but he couldn't believe he was one of them.
The tiny bikini was a perfect match with his young, petite body, and the boy felt like he was looking at someone else. He had an adorable figure, and the tiny bikini made it even more noticeable. I am a man magnet, the boy thought, and the image of himself, so beautiful, so stunning, almost made him cum.
Then he remembered his friends. If they saw him like this, they would never stop staring. They would ask him questions and demand pictures and ask him to send nudes. And he would have no other choice but to say yes and send them nudes, posing any way, they wanted. Then, he would be just like those boys in the lewd pictures. The image of him wearing a bikini like this, his tiny cock and balls on display, his smooth butt exposed, was too much. He would need a towel. Yes, a towel. A large, white, fluffy towel. To cover himself with, for now.
Katsuki looked through the drawers and found a perfect towel. It was large enough he could wrap it around his whole body, and no one would notice he was wearing a tiny bikini underneath. He took a few more looks in the mirror, then, feeling a strange warmth down his loins, the boy went back outside, his bare feet touching the grass.
Katsuki stepped out and saw his uncle, Shouto and Eijirou already sitting in the backyard table, sipping beer and eating steaks. His uncle had put on a pair of shades. His friends were no different, both looking like typical blue-collar workers. All three had their eyes on him, with Shouto and Eijirou staring in disbelief. His uncle had a different expression though. A knowing smile that Katsuki could only describe as someone who had won a great victory.
"Here he is" his uncle said.
"Well, look at you!" Shouto exclaimed. "Lookin' like a little hottie like always, boy."
"Nice towel, but what are you wearing under?" Eijirou added.
"So, how about you go have some fun on the pool?" his uncle suggested.
"Y-yeah" Katsuki replied.
Katsuki was feeling very weird. He didn't know why his body was reacting the way it was. He could feel the throbbing between his legs, his tiny cock was starting to get hard, and his nipples were puffy and erect. He tried to ignore that and walked towards the pool. He put his feet on the water and the cold sensation made him shiver. It wasn't very cold, but it was still fresh. He sat on the edge and let his legs sink in the water, which came up to his knees. Then he took a deep breath and pulled open the towel.
As soon as he did, his uncle and his friends let out a gasp and a whistle.
"Fuck" Shouto muttered.
"Damn" Eijirou followed.
Katsuki was completely aware of how his body looked. How his nipples were poking through the bikini and his penis was almost visible and how the fabric was showing the outlines of his dick. There he was, 98% naked in front of the three grown men, all of them ogling him with lustful eyes. And somehow this made Katsuki even harder.
The boy knew he was getting a hard-on, his erection stretching the dental floss of his micro bikini. It felt strange, but also good, and the boy couldn't help but wonder if those feelings were because he was wearing such a revealing outfit or because the men were staring.
"Wow, that is...that is something else" Izuku said, adjusting his pants. His two friends continued staring, mouths open in surprise.
"You look so beautiful, boy," Shouto said, his eyes wide and a smile on his face.
"That is...you're a sight for sore eyes, baby" Eijirou added, biting his lip.
"Why don't you splash around for a bit? You'll be cool in no time" the man said.
Katsuki nodded and dipped his hand in the water. He started splashing around and the cool water did feel nice. The air was warm, and the water was cool, and the contrast of the two was amazing. Soon, he was laughing and giggling, letting the water soak him. He could still feel the eyes of the three grown men on his body. Previously he had hated this sensation, but now he felt the warmth on his belly, and he enjoyed it.
The boy continued to splash around, and his friends continued watching him, their pants tented already. Katsuki was a sight, an absolutely, impossibly, deliciously irresistible beauty.
"You look so damn good" Eijirou said.
"Thanks" the boy replied, not making eye contact.
"That's the hottest thing I've seen" Shouto added.
"I think we can agree this was worth the money" his uncle smiled, adjusting his sunglasses.
"So damn worth it" Shouto repeated.
"T-thanks" Katsuki repeated, and blushed.
Katsuki wasn't sure, but he thought he could feel a strange pressure coming from his crotch. It was then that his uncle's friend Eijirou walked closer, picked the hose and began to splash Katsuki with it.
"Eek noo!" the boy squealed and tried to deflect the cool water with his small hands. He realized Eijirou was aiming with the hose to some specific parts, the jet of water landing on his barely covered dick, on his nipples or in the crack of his butt. Katsuki didn't care though. Something had changed and now he was enjoying it, even if the water was cold and his erection was obvious to everyone.
"Hehe" the boy giggled and tried to hide his hard cock.
"It's cold, isn't it?" his uncle said.
"N-No. I mean, yes. A little bit" the boy stammered.
"A little bit" Eijirou laughed and continued to douse him with the hose.
"Damnit" Shouto chimed in. "This is the best show I've seen."
Katsuki kept giggling and then bent over, his hands together to cup some water and throw it back at Eijirou, who gasped and looked at his wet clothes. He knew well Uncle Izuku and his friend Shouto had a perfect view of his ass as he did so, his pink hole covered only by that dental floss thin string.
"You brat!" The old man laughed and before Katsuki knew it, he felt two strong hands grabbing his hips and lifting him up, moving his wet, glistening body away from the pool and onto the lawn, were he felt the grass against his back and nearly naked butt. Eijirou began to tickle him, and Katsuki exploded into laughter.
"Ah! Noooo!" the boy giggled. "Please no! Hahahahaha!"
The two men watched with a smile as Katsuki was tickled by the third one, his nearly naked body squirming and trashing as he tried to escape from the man's grasp, his toes curling against the grass and his tiny cock hard and poking the bikini bottom, the small pink fabric stretching against the shape of his erection.
Katsuki kept laughing and squirming, but soon he noticed Eijirou wasn't just tickling him, instead his hands were toying with the strings of his bikini, trying to get them off. "Oh no, what is this?" the man teased.
"N-no! Ahahaha!" the boy giggled . "I wonder what happens if I pull on those?"
"Noooooo don't! Ahahah!"
"Maybe they are so small so I can take them off more easily"
Katsuki's brain registered those words, but he didn't protested. He didn't ask Eijirou to stop or called for his uncle. He didn't know why, but he just wanted to play along. To see where it all lead to. Still giggling, Katsuki replied.
"No, they are meant to...hahaha...to stay on me!"
"Well, too bad. Because I'm going to take them off"
"N-noooo" the boy pretended to protest, and his laughter increased.
"Too late, babe"
And with that, Eijirou slid his finger under the dental floss and began to slowly pull it away. Katsuki pretended to resist and kept giggling, the sound of his laughter mixing with the approving "damn!"'s coming from the other two men, who were staring at the scene. His top was pulled off, revealing his stiff, puffy nipples. Then Eijirou proceeded to do the same with his bottom.
Katsuki could only close his eyes as the old man grabbed the dental floss covering his groin and started pulling it, his tiny erection throbbing in anticipation. The man pulled slowly, dragging it across his smooth legs and thighs. He felt the fabric caress his legs and his pretty feet until finally it was off. His uncle and his friends were staring at his naked body, at his stiff nipples, his cute cock and his bare, hairless ass. And the boy couldn't help but like it.
"He's so fucking hot, I knew it" his uncle said.
"Fuck" Shouto followed.
Eijirou kept tickling Katsuki, but soon the tickling turned into caresses as his rough hands roamed the boy's naked petite body.
"So smooth" the man whispered.
"Ooooh" Katsuki managed to reply.
"Damn, look at you" the man said, cupping the boy's chest and pinching his nipples. Katsuki only moaned, squirming slowly in the grass. Eijirou began to kiss Katsuki's neck, his facial hair tickling the boy's silken skin. Katsuki giggled and squirmed, his heart beating fast and his tiny cock throbbing. He was so small, and the man was so big, it was like his entire body was being covered by the man's touch.
The feeling of his lips and tongue kissing and sucking on his skin made him feel so good, his mind going numb. He didn't even notice when he had wrapped his slender arms around Eijirou's neck, his hands stroking the man's hair and his back arching to meet the kisses, or when his lovely legs locked around his waist, pushing him against his naked body.
"Oh...oh...o-oooooh" the boy moaned.
"Damnit" his uncle whispered.
"Fuck, they're actually doing it" Shouto followed.
"I bet you're liking this" Eijirou said, pinching Katsuki's nipple again and tugging a bit "I bet you've been waiting for this all day."
"Uh...uh..." was the only thing Katsuki managed to say.
"You are the cutest, the hottest thing in the world. You're making a poor man so hard, so horny."
Katsuki looked at the man, and he could see his bulge, and he was indeed very hard. Hard because of him. Because of his body, his nakedness, his tiny cock. His instincts were kicking in and now, he knew why he had leaked that sticky liquid when he saw those dirty pictures online. Why he had put on that bikini. Why his uncle had pushed him to discover the truth. The truth that boys like him were meant to be naked and be touched and kissed and fucked by big, horny men.
A few seconds later man and boy were locked in a passionate kiss. It wasn't like the kisses his mom gave him. That was on the cheek or forehead. No, it was different. This was a real kiss, and Eijirou's tongue was deep inside his mouth, exploring every corner and making the boy moan louder.
They pulled away after a while, and then the man went back to kissing his neck and his chest. Katsuki's head was spinning, and the feeling was too good. He could feel Eijirou fumbling to undo his belts and release the iron hard beast that awaited inside.
Katsuki knew what was going to happen next. He had seen it on those pictures, he had heard his friends talking in hushed tones about how the janitor at the school would take boys to his broom closet and fuck them, making them moan and beg. He knew this was sex. And he was ready for it.
Eijirou's dick was huge, and Katsuki had to reach back and spread his ass himself to help it enter him. His tiny, puckered hole was too small, but he did his best to let the huge, throbbing monster in.
"Uuuuhhh" the boy moaned.
"That's it, boy. Just like that" Eijirou grunted.
"Oh...oh...aaaah!"
"Just like that. Relax your little asshole. Let this big old dick in."
"Ah...ah...yes! Oooh!"
"Good, good, just like that. Let it all in."
Katsuki's moans were joined by Eijirou's as his ass slowly enveloped his big cock, and soon the man was fucking the boy on the grass, his hips pounding the young beauty like a jackhammer, his huge dick reaching deep inside his body. Katsuki was a mess, moaning and panting, his tiny hard cock oozing pre-cum.
He felt he was going to lose his mind to the pleasure, but instead he found himself reacting to each trust, enticing the man to fuck him more. His legs squeezed his waist, pulling him close. His hole tightened and relaxed with every time Eijirou's huge dick slid in and out of him, and his mouth began to speak lewd, obscene things, coaxing the man to ravish him.
"Oh yes! Yes! Oh my god, oh my god! Uhhh! Ah! Fuck me! Fuck meeee!"
"You like that? Huh, bitch?!"
"I doooo! I love it! F-fuck my asshole, please, fuck me!"
"Yeah, you're a slut, aren't ya?"
"Yes, I am! I'm a slut! Uhhh, a little slut! Just for you!"
"And what do good sluts get? Huh? What do they want?"
"They want your cum, uhhh. Give me your cum, please! I want it so bad! Cum inside me, please, pleeeease!"
"Yeah, take this. Take my cum, little slut. Take it, take it, take it!"
The man came inside Katsuki's ass and the boy squealed, his cock shooting tiny strands of cum. His first anal sex orgasm. Eijirou collapsed over the boy, their sweaty bodies rubbing against each other.
As the man panted, Katsuki's felt his cock abandon his little hole, and soon he could feel a stream of cum drip from his anus, the warm liquid sliding down between his cheeks, pooling in the grass below. He felt so good, his brain couldn't process anything. He was about to speak when he felt another weight on top of him, and another hard cock prodding his gaping, leaking asshole.
"My turn" he heard Shouto whisper, and the boy was about to say something when he felt his insides stretch again.
Shouto fucked him harder and faster, his dick drilling his little hole, and the boy just lay there, moaning and begging for more. Shouto was a taller man, his large body pressed against Katsuki's naked body, something the boy found himself greatly enjoying.
Soon, he was being filled with a second load, and he could feel even more cum leaking from his ass. His cock was spent, and his body was limp, but the pleasure was overwhelming. And then the last of the three, his uncle, took Shouto's place and began fucking him.
Izuku's dick was the biggest, and it filled Katsuki up even more. But the boy was now experienced, and he began to rock his hips back and forth, enticing his uncle.
"Oh, your cock is so big! please fuck me, uncle! Make me yours!"
"Y-yes, that's it. Take this Kacchan. You like it, don't you, whore?"
"I love it! I'm a whore! A whore for your cock!"
"Yeah, that's right. I knew you would be a slut, boy. You were born to take a dick. You just were born to be bred"
"Yes, yes, yesssss! Breeeed me, uncle! Breed your slutty nephew!"
And Izuku did that. He bred Katsuki's asshole and fucked him hard, his hips slapping against the boy's ass cheeks. His thrusts were wild and fast and soon he was dumping his seed inside the boy. Katsuki couldn't even think straight anymore. The three men had taken turns and now he was laying on the grass, cum leaking from his fucked, stretched, used hole.
"Fuck" his uncle said, panting.
"D-damn" Shouto added, looking at the boy.
"Fucking damn" Eijirou finished.
"I need a drink" his uncle said.
"We all do" Shouto followed.
The three of them got up, leaving Katsuki alone on the grass, his ass full of cum and his little cock dripping the remains of his own orgasm. Katsuki got up a bit later, feeling that delicious soreness from rough sex he would grow to love.
He picked up his little bikini, something that had become his new favorite clothing. He would need a shower, but first he wanted to enjoy the water in the pool. He didn't put his bikini back on, though, not even when the sky began to darken and the men and him went inside to watch the fight.
Katsuki had never cared for MMA, but that evening he did his best to watch as he was passed around from lap to lap, sucking dicks and getting fingered while the game was on. He was lying across the couch, sucking Eijirou's dick while feeling Shouto's finger slide in and out of his well-used hole, when his uncle's phone rang. It was his mom, who called to ask how the afternoon had gone. Katsuki could hear her voice on the speaker, asking if everything was alright, but his uncle only replied with a grin.
"Everything is fine. More than fine" he said.
"Really? How so?" she asked.
"Let's just say...uncle Izuku has found a new way to bond with your son"
His uncle smiled at Katsuki, whose mouth was still busy around Eijirou's dick.
"I'm glad, can I speak with Katsuki? "
The boy left the cock as his uncle moved the phone speaker near to his face. Shouto kept fingering his boyhole though, and Katsuki did his best to not moan while speaking to his mom.
"Hi, honey. How's it going?" she asked.
"O-okay" he said, and gasped.
"How was the pool?"
"It was..." he whimpered. "It was very n-nice"
"Did you have fun today?"
"M-more than you think" he squealed.
"Good, I'm glad you are having a good time."
"Yeah, I'm haaa...having a good time" he moaned.
"Are you okay?" his mother asked.
"Yeah, it's nothing. The...the fight is a little intense."
"Okay, well, be a good boy and don't give your uncle any trouble, alright?"
"O-okay, I will" he said and gasped loudly as Shouto's fingers hit a particular sweet spot inside him.
"Okay, good night, baby" she said.
"N-night, mom"
Katsuki managed to say before being Eijirou pushed his head down to suck his dick again.
"I'm happy you two are bonding" she said before hanging up.
"Yeah, me too" his uncle laughed, and the man hung up the phone, throwing it on the couch.
Katsuki smiled, and continued sucking his uncle's friend, the three men taking turns using him as the game continued. He sucked them all off and realized how much he loved to have a dick in his mouth. He sat on their laps as they caressed his naked body, pinching his nipples and groping and jiggling his ass in their hands.
They slid in and out their fingers out of his hungry boyhole, and at one point Shouto took an ice cube from his soft drink and pushed it inside his ass, making the boy moan and squeal and letting it melt and then lick the water that leaked out. Around eight Shouto and Eijirou left, and Katsuki was left alone with his uncle. They were in the living room and his uncle was sitting on the couch while the boy was kneeling, his mouth full of the man's cock.
"Such a good, obedient boy" the old man said, stroking the boy's hair.
Katsuki just moaned in response, and he heard his uncle's voice, deep and commanding.
"How about if we go to bed early tonight, baby? Would you like that?"
The boy nodded, focused on the cock inside his mouth.
"You and me, all alone in my bedroom, just us two. I'm going to fill that little hole up and fuck you until the sun comes out, what do you think about that, my little whore?"
"Mhm-mmhmmm" the boy mumbled, his mouth full.
And Izuku did just that, he took his delicious naked nephew to his bed and fucked him several times throughout the night, breeding his little hole with his seed until Katsuki could barely move. Then kissed every inch of his young body, starting from his neck, down across his chest and tummy, across his inner thighs and ending in his feet, where he sucked Katsuki's toes, making him squirm.
They slept snuggled together, and Izuku made sure to give the boy a passionate good morning kiss and a few squeezes on his bare, smooth ass. His mother came to pick him up by ten in the morning, and Katsuki left his uncle's house but not before hugging him tight. Then he walked to his mom's car, his eyes still dreamy.
"So, are you going to tell me what happened yesterday?" his mom asked as they drove away.
"W-what? N-no, nothing happened" the boy stammered, his cheeks flushing red.
"You are acting really weird, sweetie. Did you have fun with your uncle Izuku?"
"Of course. I had the best time."
"Great! He only has us, so you need to spend time with him and make him happy, alright?"
"Yeah, I will, mom."
"Good. Now let's see if you can log in to your game when we get home, hm?"
"Okay" Katsuki replied, and hugged his bag where his laptop was, and where he had hidden his new bikini. He would be sure to wear it under his clothes next week when he went back to visit his uncle and his friends.
He couldn't wait.
