"You really need to work out with me sometime, y/n," Kirishima said. It was after hours at school and you had been discussing your workout routines to each other. "See if you're stronger than me."
You laughed and rolled your eyes at him. "I'm definitely stronger than you, dummy. I'll prove it too!" You teased.
"Carry me up a set of stairs then," he dared.
"Are you serious?"
"Come on, let's go!" He stood up off of the desk he was sitting on. You laughed nervously and held out your arms, which he promptly jumped into. You strained to hold him at first, but you gathered your strength and stood up straight. You started running, and you found a close set of stairs. You huffed and let out a battle cry as you ran up the stairs as fast as your body would allow. Once you got to the top, you let him fall quickly. You heaved, staring at him triumphantly. His eyes were wide and so was his smile. He patted you on the back and gave you a thumbs up.
"I know you could do it. That was amazing. My turn to prove my strength!" He exclaimed. You laughed and let him pick you up effortlessly. He smiled at you and walked down the stairs, and then ran back up them quickly. It seemed to be much easier for him than for you, though.
"Good job, macho man." He laughed and smiled his toothy grin. There was this way he made you feel, once which you would never admit. When he smiled or laughed, you couldn't help doing the same. Butterflies practically lived in your stomach ever since you met him. He never failed to surprise you, and that was something you liked about him. He challenged you in a way that made you stronger. And for a while now, he had felt the same way. You were good at reading him, so you knew there was something between you. You would flirt back and forth all day, only to go home alone. Bakugo couldn't stand it, he said your eyelash fluttering and his muscle flexing made him want to throw up. He usually left you two alone, which was perfectly fine with you. You liked being alone with Kirishima.
He ceased laughing, but a small grin remained. The realization of how close your faces were came upon him, and made him blush slightly. You followed suit, blushing along with him. He was still holding you, like you were merely a bunch of balloons. He kissed your forehead softly then smiled widely. His heart pounded in his chest like a hammer against a nail. Through it all, he was still that shy, timid boy underneath his confident exterior. He gazed into your eyes, hoping you could see his heart. He lacked the words to express how he felt towards you.
"Kirishima, you can put me down," you chuckled nervously. A blush rose to his cheeks as he set you down softly. You intertwined your fingers in his gently. You could feel his pulse in your hand, proving to you how nervous he was. He started leading you down the stairs again, his hand grasping yours tightly.
"Come on," he laughed. You smiled and followed him down the hallway.
"My favorite place in the whole school!" He exclaimed. You quickly understood when you came to the weight room.
"I should have known," you followed him inside, watching him stretch.
"We're really gonna see who's stronger now," he grunted, practically bending over backwards.
"Hey, don't start without me," you said, joining in on his stretching. He laughed, trying to outstretch you.
"Why are you copying me?" He joked, bending over and touching his toes.
"You're acting like you created stretching. Get off my back, Ei," you retorted. His face went red from your little nick name, butterflies floating in his stomach. You and him had this back and forth game of flirting going on for the past several months, and he loved it. He planned to tell you how he felt someday, but he truly enjoyed being your crush. He hoped that eventually you would be his girlfriend and he could talk to you confidently, but he doubted that day would ever come. Even after all this time, he felt scared to talk to you. He always said such stupid things around you, which you found cute. He thought it was devastating.
"Alright, I'm done stretching. Let's do this for real," you huffed, picking up a 45-pound bar (20.4 kilos) and put several sets of heavy plates.
"Woah, you sure you can handle that?" He said, raising an eyebrow. You scoffed and laid down on the bench.
"You'd be surprised," you remarked, before pushing it up with great effort. You pumped it up and down several times, before setting it down. To Kirishima, that was the hottest thing he had ever seen. She can bench press more than my whole body weight. Damn...
"You're so strong, Y/N!" He exclaimed, helping you stand up by pulling your hand. "That was-" he started, before catching a glimpse of your eyes. They were smoldering, almost to the point of making him melt. "Amazing." He almost wanted to kiss you, but he quickly decided against it. He put more weight on the bar, then lay down on the bench, ready to show you up. You stood behind him to spot him.
He pushed it up and down, his whole face nearly as red as his hair. "Hmm!" You mumbled. He struggled to push it up one last time, so you helped him out. "Nice, Ei," you complimented.
"Thanks," he panted. He stood up, nearly toppled over, declined your helping hand, then passed out. You stood there, staring at his body on the floor.
Suddenly you started to panic. "Kiri? Kiri are you okay?!" You yelled, shaking him. You ran to get a water bottle, then splashed a little on his face, which didn't wake him up. You felt his pulse, which seemed normal. He was breathing perfectly fine as well. "You're not... playing with me are you?" You surmised. You poked his ribs, which would normally make him giggle, but he didn't wake. After some vigorous shaking, he woke up.
"Hey..." he mumbled. "Did I pass out?" He seemed worried.
"Just for a minute. Are you okay, Ei?" You worried.
"I'm okay. I just need to go to my dorm," he said quietly. He was extremely embarrassed that he had passed out in front of you. He just wanted to prove how strong he was.
"Here, let me help you," you offered. He put his arm around your shoulder and let you stand with him. You walked him to the dorm buildings slowly, making unrelated small talk the whole way there. Now and then you glanced up at him, noticing how upset he seemed to be. His hair had fallen from its usual form, and his cheeks were flushed. Once you got there, you offered to help him even further.
"Do you want me to hang around for a while to make sure you're okay?" You asked. He thought about it for a while, holding the door to his room slightly ajar. He didn't want it to seem like he has ulterior motives other than just getting your help, but in reality he just wanted to spend time with you. He was slightly thankful for his sudden illness as he gave his answer.
"If you want to, that would be great," he sheepishly stated. You smiled and waited for him to enter. You slowly followed behind him, admiring his manly decorations. It almost looked similar to your room.
"If you need to shower or something I can just wait here for you," he said. You shook your head and crossed your arms.
"No way, I'm not leaving you alone after that. You seriously scared me!" You scolded. He laughed lightly and rolled his eyes.
"I probably just got lightheaded or something. You don't need to worry so much about me," he said.
"I don't care, I'm not letting it happen again."
"Why were you so worried about me anyway? You have such a cool head," he joked, sitting on his bed. You sat down next to him, reclining to a comfortable position.
"You know why." You took your hair down and fluffed it out a little bit, suddenly surrounded by the smell of your shampoo.
"Don't make me guess, Y/N," he said seriously.
"Ei, I'm not the only one of us who has noticed something between us recently, right?" You reluctantly tried. He pursed his lip and tilted his head at you.
"No, I noticed it too. Huh. So what are we gonna do about this then?" He asked. You didn't reply, you just sat there and stared at him. He stared back, not knowing what to say. He wanted you to say something along the lines of 'We should date' or 'Be my boyfriend, Kiri,' but you didn't say any of that. You slowly crawled up to him, and kissed him. His hand ran through your hair gently, reveling in the softness of it. You pulled back, then locked your lips with his again. He pulled you to sit in his lap, holding your waist tightly.
Your finger traced his jaw before landing on his hair, messing it up with your fingers. Your chests touched each other, melding your hearts into one. You ran your fingertips up and down his back lightly, a shudder escaping him. For the first time ever he was holding you as more than a friend. His excitement was all too obvious beneath you, poking you stiffly. You didn't want to make him feel embarrassed, but you would like to see what his intentions tonight were.
You moved your hips back and forth over his crotch, eliciting a small noise from him. He seemed embarrassed, but he didn't say anything. You continued to rub on him through his pants, creating a pleasurable friction for both of you. He pulled your shirt off, and you did the same to him. You tore off your sports bra and let out small moans as his hands touched your chest lightly. His teeth grazed your neck, leaving small marks along your skin. He licked your collarbone and kissed your neck again, blowing a cold breath on it. You moaned, your pussy throbbing for more. You ground yourself on him hard and rhythmically, sending him over the edge. He needed more than this now.
"Stand up," he whispered politely. You did so, and watched as he pulled off his pants. He sat back down on the bed. You pulled down your shorts and underwear, then took his member in your hand. You stroked it slowly, examining his face. His cheeks were bright red, flustered to see your whole body like this. He bit his lip and furrowed his brows, apparently enjoying your actions. He didn't know if he was supposed to say something or keep quiet.
You kissed the tip of him before taking his cock in your mouth, holding the base with your hand. He let out a low moan, making you aware of your skill. He brushed your hair to the side so he could see your face. He smiled, wondering how he got so lucky. "You're beautiful," he stated, grinning widely. You blushed, looking up at his face. You wanted to make him feel great. You twisted your hand and increased your pace, making him lose all sense. He hit the back of your throat, making you gag. He couldn't help but thrust a little into you, the pleasure was more than he was used to.
You removed your mouth, stroking him a few more times. You knew what you wanted, it drove you to do something daring. You crawled up so you were hovering over his lap. "May I?" You inquired.
"Please do," he laughed. You proceeded to sit on him, taking him all in slowly. You bottomed out on his lap, wincing from the size. You kissed him once more, before starting to bounce up and down. He guided your hips with his big hands, making you go faster. You moaned his name into his ear, running your teeth along the edge of it. He sighed a sweet reply into the air, filling the room with love. You wrapped your arms around his neck, holding him close. You continued to make out with him while riding him faster and faster.
He flipped you over onto your back, taking over control. He placed his hand over your clit while he started to thrust quickly. "Cum, baby," he commanded softly, implying he was waiting until you were finished till he would.
"Okay, I'm so clo-ah fuck fuck, Ei," you moaned loudly, forgetting where you were. He pounded into you hard and quick, watching your face contort and your back arch with admiration. He loved seeing you like this. He would definitely be doing this to you as often as he could. Your eyes squeezed shut and your knuckles whitened as you grasped the sheets.
He was starting to feel close as well, but he was determined. He held it all in as long as he could. You let out a long moan as you finally came, running your fingernails down his back in the process. "Oh god," you groaned, laying your head to the side, panting. He took that as a sign to finish, so he finally let himself.
He grunted as he pulled out and came on your stomach, making it just in time. He was panting as well, exhausted from the exertion. He kissed your lips softly, then got a rag from the bathroom to clean you up. He threw on some basketball shorts, then tossed you some of his clothes to wear.
"I don't suppose you wanna wear those anymore," he chuckled. You laughed and opened your arms so he would lay down next to you. His warm body met yours once again, his strong arms wrapping you up.
"So, do you want this to be a one time thing?" You asked nervously. You obviously wanted to be with him, but with teenage boys you couldn't tell if it was a hookup or something else.
"No, unless you were thinking that."
"I was hoping we could be together? Like you're my boyfriend and I'm your girlfriend," you proposed. He smiled and nodded.
"I want that too." He kissed the tip of your nose, and then your lips. He snuggled his head into the crook of your neck lovingly.
"I feel better now, Y/N," he said.
"Good." ~next day at school~
You walked into the classroom and took your seat, right next to Izuku. "Hi Y-" he started, before examining your neck. Uncanny. Those marks look like kirishima's teeth-WAIT! He screamed in his mind.
