Work Text:
Eijirou is annoyed. Katsuki has been wanting to fuck like rabbits all week. It was incredible throughout the weekend, it was fun on Monday, he put up with it on Tuesday. But now, now he needs to work and Katsuki needs to work but it's like his mate has an itch that hasn't been scratched.
Over the week, he's been sweet, aggressive, doting, savage, cycled through all the different moods he can pull during sex. He's indulged all of Katsuki's wants but it's not enough. And he knows he's going to snap soon.
Denki and Mina would laugh at him if they knew he was irritated about this, but for fuck's sake, could he get through this sludge of paperwork so they can enjoy the coming weekend? If Katsuki was just a little patient, Eijirou would keep him tied up and happy the whole time.
He has locked himself up in the study, skipped dinner so he can have some peace and quiet, and type out damage reports from when he tossed a jeep at a villain. It was necessary but the jeep is beyond repair and it cracked the pavement where it fell.
It's aggravating work and he can't wait to be done with it. Because. Because when he's done, he can finally fill out the forms to buy out the agency he and Katsuki have been working at.
It's a little surprise he has for his mate. Katsuki's been working so hard, he deserves this. Everyone will say it's too early, they should get more experience but he knows in his bones that it's the right time. Together, they can do it. Katsuki's an unstoppable force and Eijirou is the immovable object right behind him. Katsuki shouldn't have to hold back for his sake.
He sighs as he finally emails the damage report. He really needs to take a piss but he knows if he leaves this room, Katsuki will be on him. No matter, it's just one more thing to dredge through. He pulled up the ownership documents he was supposed to hand over on Monday.
He is halfway through reading the fine print when he hears the lock jiggle. He only has time to pull up the damage report on the laptop and shove incriminating papers in the bin before Katsuki bursts in.
He quickly schools his face of the panic he’s feeling. (He's never been good at keeping secrets.) and looks up at Katsuki, eyebrows furrowed.
"Katsuki, the door was locked," he keeps his tone serious, displeasure clear.
"I'm going to be the number one hero, Eijirou, it's a fucking lock, I figured it out." Katsuki huffs.
Eijirou closes his eyes for a second, trying to remain calm.
"Sweetheart, I locked it because I wanted some privacy."
"What the fuck do you need privacy for? You didn't even have dinner!"
Eijirou thinks the shouting is a bit unnecessary but who os he kidding, he knew what he was getting into when they got together.
"Kats, I just got caught up finishing some work, what did you need?"
"Some work!? That's what the assistants are there for! You know so we can have some fucking time off to live our fucking lives."
Eijirou can feel himself reaching a breaking point. They have had this argument multiple times. Katsuki knew his side and usually let it be.
"Katsuki. What. Do. You. Need?"
"What do I need? What do I need!? What I need is to suck your dick, Eijirou! You haven't touched me all day, I just wanna give you a blowjob," the blonde's voice tapered off towards the end.
Any other day, Eijirou would've felt bad about how needy he was acting, he would've pulled Katsuki into his arms, kissed him slow and deep and slid his cock down his mate's throat, and kept it there. Not today. He slams his hands on the desk, chair shoved back as he stands tall.
"You broke in here because you want, no, you need to suck my cock? Are you a deprived little slut? Didn't get full enough yesterday?"
Irritation pricks at Eijirou when he realizes Katsuki's eyes are already glazing over. He storms over to his mate and grabs his chin. Even with his chin pulled up, Eijirou has to look down to meet Katsuki's eyes.
"Oh no, you don't get to slip so fast, baby. You have been a fucking brat all week. Is this what you want? For me to keep you tied up for my pleasure? Have the world know the great Dynamight is out of commission because what he truly wants is to be a plugged hole for me to take whenever I want?"
"What the fuck, Ei?" Katsuki whimpers.
Eijirou pushes him down on his knees. He goes easily, looking up at him with hunger and devotion in his eyes. He is such a brat, probably thinking he’s getting exactly what he wanted as usual.
He unbuckles his belt and unzips his trousers, then pulls them down just enough that his cock can be free. He raises an eyebrow at Katsuki and he immediately scrambles to pull his boxers out of the way.
Eijirou lightly kicks him away and tuts at him to only use his mouth. Katsuki gulps but nods, he knows better than to argue today. He gives his cock a soft kiss over the boxers to placate him then gets to work removing them with his teeth.
It takes a few humiliating attempts but Katsuki finally manages, getting thwacked in the face as Eijirou's heavy cock finally comes free. His cheeks turn pink in shame and it doesn’t help that Eijirou laughs at him as it happens.
Katsuki frowns realizing Eijirou is completely soft.
"What? Did you think your pathetic display was enough to get me going?" Eijirou mocks, "you're not down there for a blowjob. But if you're good and do what I need right now, I might let you blow me after. See, I've been locked in here all day and haven't gotten a chance to take a leak."
"Y-you don't want me to - you can't be asking me to..." Katsuki splutters, too embarrassed to finish.
"C'mon Kitty, what's that big brain for if you can't even figure out something this simple. And I'm not the one asking. You're going to ask me."
Eijirou pauses. He knows Katsuki will safeword if he needs to but he’s just staring at his cock, expression unreadable.
"Or you can walk out and go make me dinner," he adds, letting Katsuki have another out.
Katsuki shuffles closer, pressing his face into Eijirou's thick thigh. He mumbles from there, "don't make me ask."
Eijirou yanks him back by his hair so he can see his face, "ask me, Kitty."
Katsuki's whole face is flaming. But his steely determination is back. He gently removes Eijirou's hand from his hair and takes off his shirt. He looks up, up, up at Eijirou through his lashes and tries asking,
"Ei-jirou, can I, um, will you let me, I want to -"
"What's the matter, sweetheart," Eijirou taunts, "can't even ask me a simple question, can you? Maybe I should've shoved something up your ass. You probably can't think straight, being so empty and all."
Anger flashes in Katsuki's eyes. Good. He is still present.
"Eijirou, will you piss in my mouth?"
Eijirou chuckles, "only because it's so much easier than going to the bathroom, baby."
Katsuki grumbles something under his breath but leans closer, mouth wide open.
Hot air wafts over his cock head and then it’s in Katsuki's mouth. It is so wet and Eijirou loves the silky texture of his tongue and turned-in lips. He probably would be hard already if the need to take a piss isn’t so strong.
Katsuki moans, happy to finally have his mouth full. He laves his tongue all over the head, trying to taste him properly. Eijirou has to yank his hair again and remind him,
"This isn't a blowjob. You haven't earned that yet."
Katsuki blinks at him, his lashes already a little wet. He always cries so easily.
He relaxes his tongue and starts taking him in properly. He has to stretch his jaw and open up his throat, even soft, Eijirou is going to be lodged deep in there.
Eijirou lets him set the pace, he isn’t that cruel, and honestly, nobody pushes Katsuki as hard as he pushes himself. Within minutes, his nose is stuffed in Eijirou's cropped, black pubic hair.
He slips his hand back into Katsuki's soft blonde hair, "ready?"
He gets a little nod and then he just lets go of his bladder. He groans in relief, shoving himself deeper into Katsuki's throat. He’s so far in that the hot stream pours straight down into Katsuki’s stomach.
He keeps going and going, he's been holding it in all day. The pleasure of finally relieving himself and the way Katsuki's throat works in rhythmic little contractions every time he swallows is amazing. Why didn't he do this a long time ago?
Katsuki is docile under him, letting himself be used. Eijirou pulls back from his throat as the torrent slows. He wants Katsuki to have a taste. His baby is smart and immediately seals his lips so nothing leaks out.
He spills into Katsuki's mouth, looking down at him now that he has some control over himself. His cute little nose is scrunched up, eyes closed in concentration as he obediently drinks it all down. He keeps coaxing more and more out with his tongue, Eijirou can’t stop even if he wanted to.
He watches with half-lidded eyes as Katsuki eagerly gulps it all down. Katsuki opens his eyes to meet Eijirou's as the piss dribbles to a stop.
"Good boy, you're such a good boy. Drank it all, didn't you?" Eijirou murmurs, scratching Katsuki's scalp.
Katsuki moans openly and traces his tongue around the head, cleaning him up. He looks at him with needy eyes, silently begging for permission.
"Yeah baby, go ahead, you've earned it."
That is all Katsuki needs. He immediately starts sucking and slurping, sitting on his knees and bringing his hands up to fist Eijirou's trousers. He bobs his head up and down until he’s deep throating again.
He hums and moans until Eijirou gets the hint and takes control. He fists both hands in blonde hair and starts jackhammering into Katsuki's pliant mouth. He is too riled up, there is no building up to this. He’s going to come soon.
He is honestly surprised the pissing hadn't ended in him spurting cum but there is no way he can hold off his orgasm anymore. He brutally slams deep into Katsuki's throat, feeling his balls pull up as they get ready to empty themselves.
He realizes it’s a big load, Katsuki has already drunk down so much of his piss but his mate never gives up. He swallows and swallows it all down. Eijirou pulls him off his cock as soon as he’s done.
Katsuki falls to the wooden floor with wet, desperate hacking coughs. Eijirou falls right beside him, feeling all his energy drain away. They lay there trying to calm their heartbeats.
"Holy shit." Katsuki breathes out, always the first to recover.
"You good? That was a lot." Eijirou reaches over so he can pull Katsuki into his arms.
"I'm fine, you big sap. That was really hot." Katsuki says with a roll of his eyes, its impact lessened by how he intertwines his fingers with Eijirou's.
"Still, we probably should've talked that out."
Katsuki turns to face him, "Ei, are you mad at me?"
"What!? Sweetheart, Katsuki, that was a sex thing! I would never disrespect you like that. Oh god, did you not want to?"
Katsuki cuts off his rambling by covering his mouth with his hand.
"Not this. I told you, this was hot. You know I'd safeword and I know you'd listen immediately. I mean, you haven't been around."
"Babe, we fuck every day?"
Katsuki sighs. "Yeah, but you're not talking to me. What did I do?"
"Hey, you know I hate it when you assume it's all your fault."
Eijirou hugs him, he hasn't realized Katsuki is acting out because he feels ignored. Sex is his way of initiating conversation but instead of their regular sweet after sex talks and cuddles, Eijirou has been falling asleep or rushing to work to finish up the paperwork.
Katsuki sniffles into his chest. He always gets so soft and snuggly after an intense session. "So you're not mad at me?"
"Love, you should be mad at me, you feel neglected."
"I haven't been letting you work. I should have just asked if I can help instead of being so needy."
Eijirou makes a mental note to bring up their kink list later on. He hasn't realized Katsuki's insecurities were getting this bad again and he could've easily triggered him with what he said earlier.
"I love you, Katsuki. I love when you want my time and attention. You're not needy. I've been a little distracted and you picked up on it subconsciously. I wanted to surprise you but I've been hurting you instead."
"Surprise me?"
Eijirou chuckles. "Yeah, I guess I haven't been talking to you as much because I was afraid I'd let something slip. I've been a bad partner, haven't I?"
Katsuki pushes him down and sat on top of him, his clothed ass rubbing nicely against his still free cock. Eijirou notices the wet patch on the front of Katsuki's pants. "Babe, you came? You liked it that much?"
"Shut the fuck up, Ei! Don't change the topic. What surprise?"
"Can I tell you when it's done? I'm almost there. I really wanna do this right."
"Tsk. I'll give you two days. That's it. Then you're telling me or I'll go hunting for it myself."
Eijirou smiles sweetly at him. "You got it, baby. Can I give you a bath?"
"No. You have to finish your work. I'll just shower."
Eijirou pulls him down to kiss his forehead. He can’t wait to reveal his big surprise. He is almost sorry it has caused so much trouble but grateful for the lessons they learned, both in communication and sex, through it.
