Karlito and Katsuki were like a pair of twins. They were in the same class at UA, a hero school. They wore the same kind of clothing, and ate the same food. They both enjoyed war games, and they both wanted to be heroes.
They were just alike. Karlito and Kacchan were brothers. Being African American, Karlito was adopted of course. Even then, Kacchan had never said anything about it. With everyone asking about Karlito's past, Kacchan shut them down. Sure, he was pretty angry most of the time with other people. But with Karlito, he was just chiller. He barely talked, much less cussed.
So there they were, chilling on the patio behind their house. Katsuki's dad had made it before...he left to go sleep with the town whore. Katsuki's mom never talked about it, but she was hurt. She was so nice to let Karlito stay here after he exchanged from America. When he and Katsuki bonded really well, she decided to just adopt him. She liked having him around, and even loved him like a son. (Or maybe more.)
On the patio, they sat on the bench, hand in hand. They both had a lot of stuff going on with them, but they dealt with it together. Karlito was sitting there, his afro feeling good in the breeze. Katsuki's blonde hair was fluffier than it looked. Karlito reached to massage it, which made Kacchan purr. So he did it again and again.
After some time, the two went up to Kacchan's room to play Madden. They didn't really like it. They just bought it because it was five dollars.
Karlito put the controller down after some minutes. "This is boring." Kacchan nodded in agreement. They both liked sports, but it was boring to play on the game. "Let's go over Kirishima's." Kacchan suggested. "We can't. They are out of town."
So they were out of options. Karlito just sat down on a beanie in Kacchan's room. Katsuki locked the window, so that no bugs got in. To Karlito's curiosity, he also locked the door. Maybe to be safe. Karlito lay back on his beanie, relaxing after an hard day at school.
That's when he heard the voice in his ear. Kacchan was there, suddenly licking his ear. He kissed the inside of his ear. Karlito wasn't homosexual (At least in this multiverse.) but he couldn't lie and say he didn't enjoy it. Even so, he pushed Kacchan away. "What are you doing, Kacchan?"
Katsuki cleared his throat, gathered his courage, and spoke. "I like you, even though your my brother. I know this so forbidden, but I really want to do it with you."
By it, Karlito was sure he meant sex. He asked anyway. "Do you mean sex, Katsuki." "Yeah-h." Karlito giggled a little. Even though he had been living in Japan for some months, he was still defiant of the of the orderly ideals. And, he wanted to have sex with Kacchan. That sounded so gay to him.
Karlito looked at Kacchan and said, "Yeah, I wanna do it~" Kacchan looked showed, as he didn't expect him to say yes. And now that he did, he wasn't sure what to do. Kacchan had dreamed about this moment since the beginning of the school year, but he never thought that it would work.
Karlito looked at Kacchan. "Are we gonna do it? Mrs Bakugou isn't home."
Katsuki didn't respond. Instead, he grabbed Karlito's hand and jerked him up. Both standing, Kacchan kissed Karlito. It felt really good. They both kissed for a long time, before Kacchan pushed Karlito down on the floor. He lay on top of him. Karlito merely giggled, this being his first kiss. The same was for Kacchan, but he was afraid. Katsuki just kissed Karlito some more.
"Are you just gonna kiss me?"
Karlito laughed as Kacchan grabbed his arms and lifted him up. He took off Karlito's clothing, so that he was only in his underwear. Kacchan kissed his cheek, then his neck. He bit on his neck, making a small mark. Kacchan groped Karlito slightly as he kissed his pectoral muscle. Karlito moaned softly, biting his lip. This felt good, but he wanted Kacchan to be more aggressive.
"Harder. Harder, Kacchan!"
Katsuki did as he was told. He bit on Karlito's nipple. "Wha-at?" Karlito said as he moaned sand gasped. Who new that this was this good? Kacchan moved down, kissing Karlito's chest and stomach. Karlito moaned uncontrollably. Kacchan pulled his own clothes off, all of them. He slowly pulled down Karlito's underwear.
"Why are you stalling, Katsuki?" "I'm not. This is called foreplay. So I can prepare you for what's next. And vice versa." Karlito didn't know what that meant, but couldn't ask after Katsuki grabbed his penis. Karlito moaned as Kacchan counted his length. "Three, Four, Five, Six, Six and Three Fourths, Six and Five Sixths. Pretty impressive, considering you are only fifthteen, and still growing."
Karlito chipped. "Considering you said it like that, I suppose your really better?" "You'll just have to wait and see." Kacchan then started to love his hand up and down on Karlito's phallus. It felt really good, then dry. "Make it wet, Kacchan." Kacchan nodded and slobbered all over his hand. He then slapped it onto his phallus. Those lewd sounds that it made turned Karlito on even more. So, he got harder.
Kacchan started to go a little bit faster. He wouldn't lie, he felt really good doing this. Seeing his brother's face as he did it made the joy even better. Call it what you want, but there it was. Karlito gripped Kacchan's hand and moaned. "Suck, it Kacchan!" With no hesitation, Kacchan started to suck on it. He swirled the head in his mouth, but soon found out that Karlito was sensitive in his whole penis.
Kacchan started to go up and down, bobbing his head. "Oh, Kacchan, I'm really close." Kacchan pulled it out of his mouth and jerked it off. Karlito finally came, spraying sprout after sprout of semen. Kacchan even tasted some. It wasn't bad. Kacchan then sat on the end of the bed. "Now, it's your turn. Do me, Karlito."
Karlito stared at Kacchan's member. He stroked it softly until it was really hard. "Can we do it now?" "Yeah, but let me lube it." Karlito responded. Karlito spit a lot into his hand. Then, he dripped it on Kacchan's member. Once it was properly lubed, Karlito stood. "Lay down, Katsuki." Kacchan did just that. Karlito crawled over him, then sat on his pelvis, right in front of his penis. He then rubbed his butt against Kacchan's member.
He wasn't having second thoughts. He wanted to do this. So did Katsuki. Once Karlito was hard again, he put his butthole right over his member. He got a nod from Kacchan and dipped straight down. The pain was instant. It hurt really bad, but not bad enough to quit.
He waited for a minute, then moved. It was starting to feel good, and there was no blood. Kacchan's member was spreading his insides, and it felt great. He moved up and down, to the rythym of Kacchan's heart, under his hands. Karlito moved faster, all while Katsuki moaned. Kacchan pushed up, matching his pace. Karlito was really close, but wouldn't cum unless Kacchan was there. Karlito was in bliss.
Suddenly, Kacchan started moving up and down. "I'm close." was all he said. Karlito didn't protest when he flipped him over and drilled into him. Karlito laid his arms down and let him do his worst.
Karlito came. It was a lot of semen, a lot of loaning and cursing. Kacchan pulled out, and Karlito fell of the bed, onto his knees. Kacchan shoved his dick into Karlito's mouth. He didn't protest. In fact, he let Kacchan fuck his mouth. Soon, he came. Karlito spit up semen and drool as Kacchan pulled it out.
Karlito was the first to speak. "Wanna go again?"
Katsuki smiled. "Hell yeah."
