Chapter Text
Reigen’s studio apartment is tiny and the paint is peeling, but it feels lived in and cozy. Sure, it reeks of nicotine, but so does Reigen so Serizawa’s used to it at this point. There are potted vegetable plants crowded up near the window, some of which have dirt spilling out of them and onto the floor. The couch is small and angular with an office water cooler next to it, and the TV is old and flickering; Reigen proudly tells him he got it for free at a garage sale.
When Reigen asks him what he wants to watch, Serizawa doesn’t know what to say. Sure, he’s watched movies and TV shows before, but always alone. So Reigen just flips through a few channels until he finds some crime show that looks vaguely interesting.
It turns out not to be, and within 10 minutes they wind up making out.
Kissing Reigen is good. Serizawa is pretty sure he’s not yet good at it, but it feels good. He’s learning to experiment with kissing Reigen in other places: his cheeks, his nose, his ears, his neck. Reigen seems to really like having his neck kissed, making a high pitched keening noise that he tries to cover up with a cough. So Serizawa does it again, this time sucking a little bit.
Reigen sounds breathless when he says, “D-don’t, ah, don’t leave a mark, okay? Not anywhere that customers can see.”
So Serizawa undoes Reigen’s top button, then the second one, kissing his way down Reigen’s neck as he goes.
“Moving a bit fast there, aren’t you Kah—Serizawa?”
Serizawa freezes. Is he? He just wants to keep kissing Reigen’s neck, wants to lick at the hollow of his collarbones. Carefully, he looks up. Reigen is red-faced and grinning, smoothing his hands along Serizawa’s back.
“Do you want me to stop?” Serizawa asks, pulling himself up to look Reigen in the eye.
“Ah,” Reigen glances away, then back again. “Not really. I just thought you might want to take this slow, since, you know, you haven’t done this before.”
“Why would that make me want to take this slow?” Serizawa asks, kissing him quickly. “I already know what I want.”
“And what would that be?” Reigen asks. Despite the teasing tone, Serizawa can tell the question is genuine.
“You,” he says, because it’s the truth.
“Fuck,” Reigen says, screwing his eyes shut for a second. “Okay. Alright. Lean back.”
Serizawa tries to get comfortable against the arm of the couch as Reigen stands up and goes over to dig through a drawer. When he comes back, it’s with a condom, and that immediately gets Serizawa’s attention. He’s hard in his slacks, and he ignores the impulse to cover himself with his discarded suit jacket when he sees that Reigen is in a similar state. Reigen kneels on the couch in front of him, pushing Serizawa’s knees apart. When Reigen kisses him now, he slides his tongue into his mouth, which is something Serizawa is still getting used to, and he’s not sure he likes it all that much. Reigen’s tongue also tastes…kinda gross, probably from cigarettes, but Serizawa doesn’t want to tell him.
But Reigen is untucking his shirt and sliding his hands up under it, and that’s something he’d much rather focus on. Reigen leans back for a moment and asks, “Is this okay?”
“This is very okay.”
Reigen huffs a laugh, then kisses the underside of Serizawa’s jaw. He unbuckles Serizawa’s belt and undoes his button and fly like it’s the most normal thing in the world. Serizawa has to lift his hips up for Reigen to pull his pants down but Reigen gives him a questioning glance when he hooks a finger into the waistband of his briefs. Serizawa exhales and nods.
Serizawa is aware that his cock is a bit longer than average. By how much, he’s not actually sure, considering his only frame of reference is the communal showers at the Claw gym, and he’d avoided looking at anyone else there. But that hadn’t stopped others from looking at him, and one day he’d gotten a slap on the back and a ‘congratulations!’ from Shibata who was looking directly at his dick. On the list of strange interactions Serizawa has had, that one is near the top.
So he isn’t sure how Reigen will react when his briefs are pulled down, or what the general etiquette for seeing your partners genitals for the first time even is. What he gets is a pair of raised eyebrows and a sharp intake of breath, and Reigen’s hand on him, slowly pumping up and down.
Reigen looks up at him. “If I do anything you don’t like, tell me and I’ll stop.”
Serizawa tries to keep his breathing steady. “I don’t think there’s anything I won’t like.”
Reigen just shrugs as he stops for a moment to tear open the condom. “You never know.” He rolls it onto him, and it feels weird as hell, though not to the point of wanting to stop. Then, in one fluid motion, Reigen pushes back his hair before sliding his mouth down around Serizawa’s cock, and, shit, it feels like nothing else. Even just the sight of Reigen alone, head bobbing up and down, would be enough to do Serizawa in, so he quickly starts thinking of other things, a paper, he has a paper to work on-
Reigen does something with his tongue and Serizawa can’t stop his hips from jolting a bit. Reigen hums a laugh around him at that, pulling off of him with a wet pop. “You can relax,” Reigen says with a smirk, lips red and wet, “I’ve got you.”
So Serizawa does, trying to let all the tension fall out of his shoulders like he’s been practicing. This time when Reigen takes him in his mouth he holds eye contact and moans. The noises he’s making now are sloppier and louder, moving a bit faster. He bobs his head back up, swirling his tongue around the head, then going back down. Reigen moans again, looking up at Serizawa with a blissed out expression.
With a start, Serizawa realizes that Reigen is acting. He’s pretty sure that’s a bad thing.
But he also doesn’t really want to ask Reigen to stop. He feels himself flagging as he debates if he should comment or not. On the one hand he wants Reigen to feel good, on the other hand there’s a part of him that still worries that this won’t happen again.
Reigen seems to be able to feel his hesitation, because he pushes down further until his nose is starting to press against Serizawa’s pelvis and-
Reigen jerks away suddenly, coughing. Serizawa bolts upright, hand on Reigen’s back. Reigen is spluttering, coughing into his elbow. “Do you want water?” Serizawa asks, and Reigen nods with tears in his eyes.
Serizawa quickly grabs a mug off the coffee table and cranes around to fill it up at the water dispenser, briefly wondering if those are common in apartments. Maybe he's supposed to get one, but right now he’s to busy worrying that Reigen pushed himself too far, and for Serizawa, of all people.
Reigen has stopped coughing but he hands him the water anyways. Reigen accepts it with a nod, closing his eyes as he drinks deeply, not looking at Serizawa. When it's empty he gulps down air and lets out a final cough.
“I’m sorry,” Reigen sighs, putting the mug back on the table, “I used to be able to do that, but I guess it’s been a while now, you know?”
Serizawa just nods. He doesn’t know, actually. He finds himself curious about Reigen’s past partners but decides against asking, not wanting to seem jealous. And if it’s been some time, then it doesn’t seem like there’s anything to be jealous of.
Instead, Serizawa asks, “Do you want to keep watching the show?”
“Nah, I don’t even remember what the crime was.”
“A murder, I think? They found a broken vase and a bottle of chocolate syrup at the crime scene, or something.”
“Still,” Reigen says with a yawn, “There are better things to do.” And then Reigen is looking at him again, with heat in his eyes. Then he’s kissing him, starting to pull at the buttons of Serizawa’s shirt.
“Stop,” Serizawa says, and Reigen does, pulling away with wide eyes. “I’m not sure I want to do this right now.”
Reigen looks hurt and Serizawa doesn’t know what to say to make that hurt go away. He’s not like Reigen in that regard; he doesn’t have any real experience with helping people, but that’s literally Reigen’s day job. Sure, Serizawa can exorcize actual spirits, but he’s still not very good at making the people feel better. Then Reigen smiles at him and that’s worse because Serizawa knows it’s not a real smile.
Reigen slides back on the couch, gesturing as he speaks. “Well, it is getting late after all, we can call it a night.”
“Can I take the condom off now?” Serizawa blurts out, and Reigen laughs.
“Of course you can. Honestly, I don’t think we really need it, considering that I’m clean and you’re a virgin—“ Reigen looks at him curiously. “You, uh, are a virgin, right?”
“I am.” Serizawa isn’t exactly ashamed of it, but it still feels weird to talk about.
“Good, good. Well, not good, I mean, but not bad or anything, I just was worried that you had sex sometime while you were at Claw, but everyone there was pretty terrible, so that would be kind of bad. And then I’m pretty sure the only other time you could have had sex would have been when you were a kid, so that would be bad too.”
As Reigen rambles, Serizawa peels off the condom and levitates it over to the trashcan, then picks his briefs up from where they’ve landed under the coffee table.
“You can crash on the couch, if you want,” Reigen says, in a way that Serizawa hears as ‘I want you to stay, but I don’t want to ask.’
So Serizawa says “Sure,” and starts putting his briefs back on.
He cleans up under the fluorescent light of the bathroom, scrubbing at his face with warm water. He needs to shave and brush his teeth, but he's not sure if Reigen has an extra toothbrush or razor, so he skips it for the night. When he comes back into the main room, Reigen shoves a blanket and a pillow into his arms.
“Night,” Reigen says, giving him a quick kiss on the cheek as he passes by to go into the bathroom.
“Good night,” Serizawa says, wanting to reach out, and the door clicks shut.
The apartment suddenly feels too dark and too quiet. For a moment, Serizawa feels like he’s back there, in the same place again, but the distant sound of cars and the feel of the heavy blanket in his arms keep him in the present. Then he hears a muffled bang from the other room and Reigen swearing.
“You okay?” Serizawa calls over his shoulder.
“Just stubbed my toe!” he hears through the wall, and smiles.
He settles in for the night, finally taking his shirt off all the way and pulling the blanket over himself. The couch is too short for his legs and the wooden frame digs into his spine in all the wrong places. He shifts over onto his side and pulls out his phone, trying to curl up and get comfortable.
If he can't sleep he might as well do some reading.
