“Katsuki, are you hard?” Eijiro asked with an amused tone and a shit eating grin, laying on his side, propped up on on elbow. They were both laying on the same mattress, formal suits still on, after their first hero gala as pros. Katsuki had insisted on crashing at his place since it was closer to the even and he didn’t trust Eijiro to get home safe while drunk. The idiot was too friendly and trusting for his own good.
“Shut up, Shitty Hair, sometimes it happens when I’m drunk” Katsuki was covering his eyes with his arm, lazily but strategically. He couldn’t let him see how fucking flustered he was. His pants were tight due to his throbbing cock. He would just pretend he’s feeling dizzy from drinking more than he should’ve, he just wished Eijiro would drop it after making that embarrassing observation.
Yeah, true, Katsuki got hard because he was drunk, but it wasn’t only that. Having Eijiro so close, dressed nicely for the gala, shirt open, tie hanging loose from his thick neck. Sleeves rolled up revealing his veiny forearms, an inevitable consequence of hard work and diligence. Hair disheveled from hugging almost everyone at the party, even after having spent a good chunk of the afternoon pouring gel to get his hair spiky. That sight for him was heavenly. And his friend scent, a mix of sweat, faint lingering perfume, warm and familiar. Couldn’t blame a guy for getting hard witnessing that.
“It’s alright man, don’t have to be so defensive about it” Eijiro said now looking at the ceiling, arms supporting his head. “Want some help?”
“The fuck did you just say?” Katsuki almost stuttered, his heart racing, he wants the earth to swallow him whole. When Eijiro got drunk, he had even less filter than usual.
“I said, if you need a hand?” he asked again, turning to face him and poked his cheek “hey, look at me” he grabbed Katsuki’s wrist, trying to make him stop covering his face. Katsuki let him.
“Don’t joke with that” Katsuki tried to keep his usual scowling expression, but failed to do so. They were so close, now Eijiro’s index finger hooked on one loop of Katsuki’s pants, tugging playfully.
“I’m not joking, I mean it. Or if you don’t want help you can jerk off in front of me, I don’t care. I’ll close my eyes and pretend this never happened” his finger let go of the loops.
Katsuki run his sweaty fingers through his hair and sighed. “You really mean it? Like what, a hand job?”
“Yeah, I’ll give you a hand if you give me yours. That’s what friends are for”
“I’m not sure friendship means touching each other’s dick” Katsuki breathes out.
Friendship, right. A blurry line they have been walking across since their first year at UA. Lingering looks, crashing at each others dorm and sleeping in the same bed even if they didn’t need to, wearing each other’s clothes, inviting him as his plus one at events… whatever they were now, was a relationship loaded with unspoken desire.
“Relax, you have done something like this before with Izuku, right?” Eijiro asked because he knew almost everything about Katsuki, everything and anything but his sex life. So he made a wild guess, he had seen how Katsuki stayed over at Izuku’s dorm back when Izuku confessed to Katsuki he thought he liked guys too at the end of their third year. But when Katsuki stayed? Silent, Eijiro realized he fucked up and why. “Oh, sorry man, I thought- I don’t think… that was insensitive, sorry”
He remembered comforting Katsuki after Izuku told him his heart was set on Ochaco, and that he didn’t feel much after whatever happened between them. At the time, Katsuki didn’t reveal much and Eijiro didn’t push him. Rejection sucks when you’ve pining over someone for so long, and when you’re finally given a chance, turns out they are not that into you. Why? Simply because you’re not her. So it was still too soon to talk about Izuku, he was still a sore spot for Katsuki.
“Just shut up” Katsuki mutters “just come here” he turns to his side to look at his best friend. Eijiro doesn’t doubt for a second, he scoots closer to Katsuki and reaches for the belt to unbuckle it. “Not going to kiss me first? That’s not very manly” Katsuki teased. Eijiro grins at that, he knows he fucked up when he mentioned Izuku, but apparently not beyond repair. He plants a kiss on the corner of Katsuki’s mouth.
Before Katsuki could catch up, Eijiro resumed with shaky hands the task of taking off the belt, a metallic click, the leather belt undone.
Eijiro had some experience and usually carried himself with confidence and boldness, but now his nerves sobered him up a little. This wasn’t a random guy at a bar, this was Katsuki Bakugo, his best friend, the same person he has had a crush on since they met back at high school. He didn’t want to fumble things more than he already did, didn’t want to loose the chance to show Katsuki how much he liked him. So carefully he slid down the dress pants and asked “Can I?” waiting for permission.
“Go ahead” Katsuki said, still hiding his face.
Before going forward, he wiped his hand against his shirt to dry up the sweat caused from the anticipation. Then resumed to free his friends cock from his boxer. He had seen it before, many times while showering at the locker room or at onsens, but it didn’t compare to this moment.
His cock was thick, shorter than his own, but it was so fucking pretty, soft skin, absolutely perfect, like everything about Katsuki. Eijiro ran his finger across the length which made his cock twitch. He wouldn’t just jerk him off quickly and roughly, no. He would take his time, making sure Katsuki felt really good, thanks to him.
When Katsuki’s hand reached for his cock, he said “no, let me do this for you. After you cum, you can help me out. Now relax.”
With one hand, he stroked his friend’s cock, started slow but with a firm grip running all along the base, and when he reached the tip, he smeared the precum briefly with his thumb. After testing out the rhythm, with his free hand, he started massaging the balls. Focused on the sound the other made to adjust his technique.
“Does that feel good?” he asked and Katsuki hummed.
Who would’ve thought Katsuki would whimper so prettily for a hand job? Eijiro sure didn’t, he always expected him to be more into grunting. He felt his chest warm at the sight, seeing his confident friend still hiding his face. But even if he was feeling shy, that didn’t stop him from buckling his hips ever so slightly, asking for more speed, a faster rhythm.
“Can you kiss me while doing it?” his voice was a bit shaky.
“I can, but you have to stop hiding your pretty face” he whispered adjusting himself to be closer, slowing down his motions a little. And so, reluctantly, Katsuki let his arm down. Fuck, his eyes were glossy, lips parted, a look Eijiro had imagined many times, but never pictured it quite like that. He leaned on and kissed him.
Katsuki pulled from Eijiro’s tie, to pull him closer, teeth clashing against each other, a clumsy kiss. That’s what happens after holding back your feelings for your best friend for so long. Eijiro run his tongue against the other’s bottom lip, and almost instantly Katsuki’s legs and feet tensed, pulling harder from the tie, he cummed without warning.
“Sorry” he said and tried to cover his cock to stop the cum from flying everywhere, but Eijiro kissed him back into the mattress. “Don’t worry, we’ll clean up later” he whispered while giving his cock a few more strokes before letting go.
Katsuki was catching his breath, while Eijiro reached for the tissue box on the nightstand, he handed him a few tissues and used a couple to clean off the cum from his neck, shirt and hair.
“Shut up” Katsuki said.
“I didn’t say anything” he raised his hands in mock offense?
“I know what you’re thinking, I just get allergies in the morning” he huffed while cleaning his stomach with a few tissues. “Sorry about your hair.”
“It happens, don’t worry about it” he leaned down to kiss him again.
This time he didn’t stop Katsuki when he reached for his cock, he laid down and helped him by taking off his pants. A shiver went down his spine when he felt his calloused and sweaty hand reaching under his boxer. He took off his boxer, eager to free his cock finally.
“The hell? Why is it that big?” he whispered, adjusting his hand to grip comfortably Eijiro’s thicker and larger cock. His fingers barely reached around. Eijiro couldn’t stop himself from smiling like an idiot from that comment. “Don’t laugh idiot, or you’ll have to jerk off yourself in the bathroom” the tip of his and his cheeks got red.
“I’m not laughing, I’m just glad you like it” he said looking up at him, holding back his smile.
“Shut up” he muttered and kissed him, now stroking his cock with both hands with a steady rhythm that made Eijiro whimper.
Katsuki wasn’t rough but he liked teasing him, stretching the hand job as much as he could, slowing down the rhythm when his breathing got faster, letting go of his grip when Eijiro buckled his hips.
“Don’t pout, are you going to let me do my thing? Or you just want to fuck yourself into my hand?” when he shook his head, the other gripped back his cock. “Good, let me make you feel good, after what you did, least I can do” he whispered, laid his head on Eijiro’s warm chest. Katsuki didn’t feel shame about having no experience, it wasn’t about that but wanting to do things his way, no help involved. He wasn’t feeling that shy anymore, not after cumming all over his best friend a few minutes ago.
With his free hand, he unbuttoned Eijiro’s shirt, took of the tie and grope his chest. “You’re working hard, huh? It shows” he planted kisses all over his chest, nibbling his skin. A smirked tugged his lips when he saw that desperate expression, feeling proud he was the cause of that.
“F-faster?” Eijiro pleaded, his fingers reaching out for Katsuki’s cock.
“Don’t rush me” he slowed down the rhythm a little “and keep your hands to yourself” then the speed picked up again. Maybe despite his inexperience, reading smut on the internet had really paid off.
“Fuck, Kats, I’m close, where?” he asked breathless, where to cum, his hand reached for Katsuki’s neck to pull him close for a kiss. But before he could either kiss or answer, Eijiro tensed and ropes of dense cum painted the sheets, their stomachs and Katsuki’s hand and arm.
Katsuki wiped the cum on his hand over Eijiro’s chest while smiling. “Hey! Don’t wipe on me” he protested but noticed it. A genuine, playful smile, the kind Katsuki had when he figured something out.
“Tch. Come on, let’s just take a shower or whatever” he got off bed to turn on the shower.
“Together?” Eijiro asked, propping himself up with his arms.
“Do you even have to ask?” he saw the confused look on his friends face and said “Yeah, together, dumbass.”
Katsuki turned on the shower, adjusting the water to be scorching hot, just how he liked it. Meanwhile, Eijiro gathered both of their clothes and let them in the laundry basket in the bathroom.
“You’re coming in or what?” Katsuki asked lathering the soap and cleaning his arms.
Eijiro came in the shower with him, it was small so their bodies touched, the steam made it hard to see much. He was handed over the soap, Katsuki’s gaze on his lips and then quickly back up his eyes. Without asking, he wrapped his arms around him and kissed him again.
“So, are we just friends or?” Eijiro asked, gripping his waist now.
“Can we talk about this after the shower?”
“Please” Eijiro whispered. “answer me, Kats, I’ve been feeling things for you for so long, I just can’t-”
“More than friends” Katsuki cut him off before kissing him again. Before they knew, the water was running cold, but who cares? They could warm each other in bed later.
