Kirishima tried his hardest to be the best friend to bakugou. He loved bakugou a whole lot, so much that he would do anything for him. So when the frustrated boy wanted to hang out after school, kirishima was ecstatic!

When Kirishima woke up to the prickly boy cuddling him, he was slightly confused, but he loved his bro! Any affection Katsuki wanted to give him, he'd be more than happy to take. Bakugou's hand was cupping kirishima's cheek so delicately, and he was looking at him with such sweetness and care. Kirishima blushed. Bakugou was such a manly friend! "Shitty hair...." bakugou's thumb tugged kirishima's bottom lip down a bit. "... You're so beautiful..." bakugou whispered. Kirishima blushed harder. "You too, man!" Bakugou smirked and started to lean in, his eyes fluttered closed. Kirishima was way too confused when bakugou's lips brushed against his slack ones, a pink tounge coming out to lick over his lips. Kirishima whined, pushing bakugou away. Bakugou looked at him so hungrily. "Why'd you stop me, shitty hair?" He growled seductively. Kirishima wiped his mouth shyly. "Y-you... you kissed me..." he was in disbelief. Surely bakugou had to know that friends didn't normally kiss, right? Kirishima had to tell him! But when bakugou's lips pressed against his again, he couldn't find it in himself to make bakugou stop. Kirishima didn't want to take advantage of bakugou's kindness, but he liked the way the boy's lips felt. If bakugou wanted to kiss him, he didn't want to say no.

After that, bakugou was a lot more affectionate with kirishima. Snuggling close to him, holding his hand, kissing him randomly. Kirishima was slightly embarrassed, but bakugou was showing the world how good of friends they were. Bakugou wouldn't dream of kissing his other friends, kirishima was special! That made him feel warm inside. He loved his bro so much!

When bakugou's hand trailed down kirishima's shorts in the middle of one of their cuddle sessions though, kirishima had to say something. He grabbed the hand in it's tracks. "B-bro... what are you doing?" Bakugou looked at him confused. "You don't want to?" Kirishima gulped. Want to what, exactly? Curious, he let go of bakugou's hand and snuggled a little closer to him.
Bakugou grinned as he shoved his hand into kirishima's shorts. He squirmed so cutely as the hand explored his manhood. "Hahhh! B-bakugou!" He whined. Bakugou grinned harder as his hand dipped lower. "Don't worry, shitty hair. I'll make you feel good." That sounded very... dirty. Bakugou's finger pressed against kirishima's ass and kirishima gasped as bakugou pushed in, fingering him so gently. He didn't know bakugou could be so careful. But it felt so good, kirishima didn't want it to stop.
"Do you like that, shitty hair?" He purred. Kirishima nodded, a choked moan coming out.
Bakugou shoved in another finger, jabbing his prostate, forcing pleasure into kirishima.
"A-ah!" Kirishima yelped as bakugou's hand tore out of his pants, coming with the other one to wrap around his waist. He was so, so confused. Bakugou thrusted his hips into him, grinding his black jeans into the soft fabric of kirishima's basketball shorts. "B-baku-" One of bakugou's hands moved from his waist to his mouth, covering it roughly. "Shhhh... don't say anything else, shitty hair. Just enjoy this." He groaned, humping kirishima through their clothes. His other hand pushed kirishima's tank top up a bit, he was getting more violent and feral. Kirishima just helplessly panted into bakugou's hand as he worked his hips back against him. Bakugou bit him on the shoulder to muffle his own groans of pleasure.
Kirishima finally flipped over to face him, dislodging all of bakugou's hold on him, and pinned him down to the bed with a feral look of his own. Bakugou was blushing so much, panting and looking at Eijirou with a look so relaxed and blissful, It looked like he was on the best drugs ever. He spread open his legs under kirishima, to make room for him. Kirishima released a growl, rutting against bakugou. "So... so manly..." Bakugou's legs wrapped around his waist tightly, his arms wrapping around his back as he groaned again. "Yeah, I'm so /fucking/ manly. You just wanna fucking rail me... you wanna bury your fat cock in my manly ass... and you want me to do the same to you, because you want a fucking man to make you his bitch." Bakugou bit down on his shoulder again, groaning louder. Kirishima's back was being clawed by bakugou but he didn't even care. Everything he was saying was true. He always dreamed of serving a manly guy however they wanted him. Bakugou was the manliest, and kirishima just wanted to be used by him, to belong to him. Being his best friend was more than good enough, though. Kirishima didn't want to be greedy after bakugou had given him so much already. His hips didn't stop moving, gyrating into bakugou's. He was in so much pleasure and bliss. He just felt himself getting closer and closer to that wonderful edge.
He was going to cum dry humping his best friend. He swapped between snapping his hips into bakugou's and pressing roughly against him, rutting their cocks together. He could feel bakugou's hands gripping him tightly, his heels trapping him in place, his teeth digging into him. "B-bakugou...! I'm... I'm gonna..." He couldn't hold it in any longer. "C-cum!" He moaned as he released inside his shorts, hips still working into bakugou's. Bakugou gripped his hair and moved his teeth from his shoulder to his neck as his thighs shook. Kirishima, determined to help him, never slowed his pace, ignoring the oversensitivity seeping in. He bit down on kirishima's neck hard, definitely piercing his skin as he grunted so brokenly, cumming in his pants as well. "Eijirou... you did so fucking good. ...Good boy." He stroked his red hair gently. "...Thank you..." Kirishima grabbed his face. "B-bakugou..." "Katsuki" he interrupted. "Katsuki... don't thank me... thank you, thank you, thank you for letting me... make you feel good." He smiled warmly at him. "I fucking love you, shitty hair." Bakugou clashed their lips together and kirishima melted into it. He loved bakugou, too. He was his best friend, after all. In fact, kirishima... might've just had some... feelings for him.

He didn't know if bakugou felt the same though.

Kirishima couldn't hear anything over the crowd screaming. "Red riot, did you see-" He tried to weave his way through people as quickly as possible, but it wasn't so easy when he had people asking him questions, touching him, grabbing him. "Red riot! How do you feel about-" He really didn't mind that much but he needed to see what was going on.
He finally worked his way to the front of the crowd to see his best friend and hero partner on the ground. He quickly ran over. "K- Dynamight!" He hoisted him up by his shoulders and hugged him tightly, prompting an "Awww~" from the crowd. He almost flipped them off for Katsuki.

Katsuki looked up at him and kirishima's breath caught in his throat. He looked so dazed and flushed. "Eijirou~" Katsuki purred, stroking his face. "You're here..." Eijirou gulped. Katsuki sure was showing a lot of affection for his bro, especially in front of all these people. He picked him up and Katsuki nuzzled into his chest, prompting more cooing from the crowd. "I wasn't fucking scared, I knew you'd come for me if things went south... you're so fucking great, Ei." He pulled him in closer, pressing his lips softly against Eijirou's ear. "I kinda wanna make you come for me again, in a different way..." he smirked. Eijirou laughed nervously. "W-what do you mean by that, Bakugou?"
"What do you think I meant? You know how I get when you save the day like this? When you make me look like some pathetic damsel in distress?" Eijirou opened his mouth, arguments already forming in his mind about how bakugou didn't look pathetic, he looked so strong and brave and se- ...manly. ".. Fucking... turns me on. Goddamn, shitty hair... you don't even wear a shirt... you have this..." he ran his fingers over Eijirou's mask. "...Bdsm muzzle... you're a feral animal, huh? Need to be restrained so you don't bite?" Heh. He could talk about himself like that. Eijirou was the strong, collected one, the one in control of the situation. Katsuki was a hot-headed, emotionally stunted mess. He loved him.
"I look hot in your arms, don't I?" Katsuki smirked. "Well? I wanna see you pleasuring the shit outta' me, so let's get to it." Eijirou whimpered when their lips crashed together. By that time, they had walked away from the crowd of people. Eijirou was glad for it. He didn't want Katsuki's hero ratings to be affected because people mistook them as a couple.
Sure they bought a house together, shared a bed, made love in that bed, and talked about some day having kids, but it was like that at UA, too.
Their friendship was deeper than most. Ever since Kamino they had been inseparable, eventually bakugou got touchier, and when Eijirou enthusiastically took everything he gave, he gave more, he kissed him, and eventually had sex with him.

Eijirou was always so insecure about Katsuki maybe someday meeting someone and going on dates with them, of fucking them, of loving them instead of Eijirou. Sure Katsuki would always love him, he told him that every day, but what if bakugou realized that Eijirou wasn't good enough for him, that the other person could give him more? Eijirou had absolutely ravished Katsuki that night, worshipping him, praising him, giving him sweet kisses and whispering "I love you" Katsuki had loved it, but when Eijirou crawled up beside him and whispered a desperate "please don't leave me..." Katsuki had cupped his face so gently, kissed him so lovingly. "Don't be a fucking dumbass. I would never, ever leave you, Eijirou. You're my everything. The world is so fucking tough and hard, but you're so warm and soft... and red. God I love red because of you." Kirishima blushed. He really loved Katsuki...
"No extra could ever compare to you... you're my perfect match. You were fucking made for me... like some Adam and Eve type bullshit. I would never even think of leaving you."
"I..." Eijirou sniffled. "You're my best friend, my other half, Katsuki... I just love you so much... I don't even know what to do sometimes..." Katsuki kissed him again. "Marry me." Eijirou's eyes widened. "Wha-What?" He whispered. Katsuki flipped them over so he was straddling him. "Marry me, Eijirou. Let's have a wedding and rub it in everyone's faces and release some stupid pigeons because you like them and let's get married." Eijirou gulped, shaking. "T-that sounds... so romantic, man..." Katsuki smirked. "It's supposed to." Eijirou's eyes widened in realization. He loved Katsuki so much it burned, he always had, he thought he was sexy and brave and manly and... and Katsuki felt the same way. "I love you..." Eijirou trembled. "I really, really... want that wedding..." Katsuki smirked, pulling off his shirt. "Good. It's non-optional. I love you so much, Shitty husband." He fished kirishima's cock out of his pants and began stroking him. "Round 2, fucker." He smirked. Eijirou just let his head fall back with a whimper.
