Izuku was sitting between his boyfriend's legs, resting against his chest as they watched training videos on Izuku's laptop as part of their hero basic training homework. As exciting as learning CPR was, Izuku's mind was elsewhere.  "Kacchan?" Izuku looked up as the video ended.  Kastuki hummed and turned to see what Izuku wanted.  "Can I top tonight?" Izuku asked quickly with a light blush. "Eh?" The question caught Katsuki off guard.  Izuku started to explain, "Well you know you always do it to me," Kastuki rolled his eyes because heaven forbid Izuku use the word fuck, "and it feels really good and I want you to feel good like that too- Ah um not that you don't already feel really good when you're doing it to me but this is a different kind of feeling good I think and I thought maybe you'd like mmf-" Izuku was cut off when Katsuki kissed him to shut him up, a method the blond had found to be effective when they started dating. Katsuki pulled back with a huff. He had to admit he was curious what felt so good about being fucked in the ass but still he didn't know if he was willing to let Deku be the one doing it. Something about that just didn't sit right despite having known him almost all his life and having been the one to ask out the idiot in the first place.  Izuku shifted so he was facing Katsuki and put on the cute face he knew his boyfriend was weak to, "Please Kacchan can we try? If you don't like it we can stop and you can do me like usual." Katsuki sighed. If Izuku liked it so much it shouldn't be a problem for him to get fucked like that, "Yeah alright, but you better make it good." He threatened teasingly.  Seeing Izuku light up with excitement and hug him tightly made Katsuki think this might be worth it just for this.    ===============================================================================   Maybe this wasn't going to be worth it after all, Katsuki thought as he looked up at Izuku, who was smiling excitedly. Both of them were already naked, that part didn't bother him considering he'd been naked with Izuku dozens of times now, but seeing the weaker boy over him like this and knowing what was going to happen was starting to make him nervous. Which was stupid because Katsuki could handle anything stupid Deku could handle after all.  "Well?" Katsuki raised an eyebrow questioningly at his boyfriend, who hadn't done anything yet but look at him.  "Ah sorry!" Izuku seemed to snap out of whatever daze he was in and blushed, "I was just trying to decide what I should do..." Katsuki snorted and reached down to start stroking himself, "Just get straight to it, I don't want you teasing me all night." Truthfully he just wanted to get this over with but he figured Izuku would view it as him just being impatient.  Izuku gave a quick nod and sat back, grabbing the lube. He covered his fingers with more than was probably needed and rubbed it around so it wouldn't be cold. "Tell me if you want to stop ok?" Izuku said as he slowly inserted the first finger.  "yeah yeah don't worry so much," Katsuki said trying not to cringe at the feeling. It was weird but didn't hurt or anything.  "Can't ya kiss me or something while you do it or is that too much for you?" Katsuki complained after a few moments of Izuku just wiggling a finger in his ass. He would like something else to focus on. "R-right," Izuku moved so he was over Kastuki again while still being able to finger him. He stared kissing Katsuki gently, and Katsuki gripped both hands in his hair and deepened the kiss, attacking Izukus mouth like he usually might.  Izuku took this as an opportunity to insert a second finger and Katsuki inhaled sharply at the intrusion. However he quickly resumed making out with Izuku before the other boy could comment on it. This wasn't anything he couldn't handle if Deku could handle it. The distraction worked well enough until Izuku decided he was ready for a third finger. Kastuki bit his lip to stop any noise from escaping at the feeling of being stretched even more. He wasn't seeing what Deku liked about this yet because while it wasn't painful it wasn't exactly comfortable either.  "Is this still ok?" Izuku asked, stilling for a moment as Katsuki pulled away from him.  "'s fine." He didn't need concern and especially not from Deku.  When he didn't start kissing Izuku again, Izuku decided to play with one of his nipples, licking and sucking at it teasingly. Katsuki shivered. Sure he did this to Deku sometimes but he still thought of it as something girly that mostly girls liked. Why would a guy want to have his nipples played with after all?  Deku was just weird for liking it and was kinda girly anyway. Katsuki wasn't a girl and he refused to like the feeling of Deku teasing him like this. He felt tears start to form in his eyes and blinked them to try and stop it.  "Just hurry up already!" He bit out. It felt like Deku was taking forever prepping him. He wasn't weak; Deku's dick wasn't going to break him.   While Izuku stopped playing with his nipple, he didn't pull out his fingers just yet, stretching him a few more times just to make sure he really was ready. Finally he he pulled them out though and Katsuki let out a breath of relief that he hoped Deku didn't notice.  "Do you want me to wear a condom Kacchan?" Izuku asked hesitantly. He looked up to see Izuku looking at him with a mixture of want and uncertainty. They typically didn't use one because they were both clean and for fuck's sake he wasn't gonna get pregnant after all so why was he even asking? The only times they did was when Deku didn't want a mess to clean up and he knew Katsuki didn't care if they made a mess.  "No," He growled, irritation clear and trying to hold back more tears. Unfortunately Izuku was starting to notice, "Kacchan you don't have to-" "Will you just fuck me already!" He yelled, accidentally setting off a few tiny explosions and burning the sheets as a few tears escaped and rolled down his cheeks. At this Izuku scrambled to lube himself and grab Katsuki's hips to line himself up. Still a bit unsure, he made sure to go slow in pushing himself in and carefully watched for any signs that he should stop.  Katsuki bit his lip and held back a sob at the feeling of Deku inside of him. This stretch was uncomfortable but still nothing he couldn't handle. He kept telling himself that Deku could do this and he was way stronger than Deku.  "You feel so good Kacchan," Deku moaned as he bottomed out, "Just tell me when its okay to move yeah?" "Stop treating me like I'm going to break!" Kacchan sobbed, unable to hold back any more. "I'm not weak and I'm not a girl! Fucking fuck me!" Izuku was taken back and debated just putting a stop to this and pulling out, but he wasn't sure if that would just upset Kacchan even more. So instead he started to move in slow gentle thrusts, starting to look for the spot that he knew would make Kacchan feel better.  Katsuki let out more frustrated explosions, "I said fuck me!" He cried. He didn't care if it hurt or Deku was rough because he wasn't weak and he could fucking do this. Who was Deku to treat him like this when he was even weaker than himself? He started crying harder. Izuku hardened his resolve and grabbed one of Katsuki's legs, lifting it so he could thrust at a better angle. He started moving faster and harder, trying desperately to find it.  Finally he hit it and Katsuki arched with a gasp. "That do that!" He cried because finally something felt good.  From then on Izuku tried his best to hit the spot with each thrust until they were both desperate for release and making Katsuki forget about his feelings of being weak.  "Deku please," Katsuki sobbed needing to cum. Izuku hummed and started to stroke Katsuki in time with his thrusts.  Katsuki cried out when his orgasm hit him and he felt Izuku follow, the hot liquid releasing inside of him. Carefully Izuku pulled out and looked over Katsuki to make sure he was okay. He reached up to wipe the tears away and Katsuki let him, too fucked out to care anymore.  Izuku struggled for a moment, thinking of what he should say because an apology probably wouldn't go over well, before settling on, "Thanks Kacchan." Katsuki pulled him down into a chaste kiss before rolling them over so he was on top again. "Yeah whatever. I think I like you better this way though." He tried to sound as if he hadn't just been crying and only partially succeeded. Izuku smiled softly and brought Katsuki down for another kiss, "I'm okay with that."
