i only keep myself this sick in the head ‘cause i know how the words get you (off)

Summary:

“Ahaha, so sorry. Would you prefer me to be nice to you? Do you want me to call you a ‘good boy’, Keiji?” Shin asks, clearly amused.

God, at this rate he might as well be the detective with all these fucking questions.

Even as Keiji feels his face heat up, he isn’t going to give in just yet. “I’m no dog, y'know,” he responds lazily.

Shin raises his eyebrow, seemingly unimpressed by his response. “Well, they’re big, dumb, and obedient. Sounds just like you!” He caresses his cheek gently, quite contrasting to his harsh insult.

Wahaha, now I’ve got nothing witty to say to that.

Work Text:

Keiji can tell every move Shin makes is intentionally slow. Painfully slow. The asshole wants nothing more than to torture him, dragging everything out until he can’t take it anymore. There was the way he slowly unbuttoned his shirt and vest in between kisses. He was used to his chest being admired, but Shin’s eyes thoughtfully scanning over him usually suggested danger. Or, there was the way he took his sweet time to throw a leg over his waist and handcuff him to the headboard, “unintentionally” grinding against his groin to “adjust” the restraints. Before Keiji’s hands got even a second to explore the other man’s body, Shin dangled a pair of leather handcuffs in front of his face with an innocent smile. Like usual, he couldn’t resist a challenge. 

Shin sits in his lap, straddling his waist. Keiji looks him up and down, trying his best to predict the other man’s next move. Despite his best efforts to stay focused, he gets easily distracted, rightfully so. Since Shin has already discarded his hat and scarf, Keiji takes the opportunity to get a good look at that dangerously pretty face. 

He’s got nice and soft features, too bad he likes to hide ‘em. 

He leans in closer to him, wrapping his arms around Keiji’s torso. “Ahaha, the ex-detective caught in handcuffs? How ironic…” He says just barely above a whisper.

Of course, he’s not all that nice himself.

Sure, he’ll let Shin have his fun. But Keiji isn’t going down without a fight. Truthfully, both men crave this game of back and forth; the struggle to get on top. Literally.

“Haha, well, I suppose cruel irony is nothing new to me,” he remarks. 

So much for biting back, all you did was make yourself sound even more lame.

Shin turns his head and smirks. He then grabs onto his chin, squeezing his face a bit. He has a surprisingly firm grip that makes a quiet grunt escape Keiji’s lips. He giggles, “You really are pathetic, aren’t you?” 

Although he spoke in a slightly condescending tone, Keiji didn’t feel like it was an insult. If anything, it seemed like the idea thrilled Shin even more. While this certainly isn’t the first time one of his lovers referred to him as pathetic, it was perhaps the first time it was said with such excitement. Typically, it would be listed as one of the many reasons why they couldn’t stand him. 

“Ouch, you really know how to hit a guy where it hurts,” he chuckles, flashing his signature smile — the one that was usually an attempt to appear composed and totally not nervous at all. 

Shin leans his head down even further, his lips just barely an inch away from his ear. “You bet, and I can make you hurt even more,” he whispers in a low and seductive tone. There was no way Shin didn’t feel that traitor down below twitch against his ass. He giggled once more, meaning Keiji guessed correctly. 

Lucky me. 

Keiji suddenly feels a bit vulnerable as he watches the other man’s eyes drag over his body. With his arms being pinned above his head, he can only watch. Shin drags a finger up his arm, seemingly tracing his muscles. 

The blond closes his eyes, trying to recall how he got himself into this. Some play-fighting led to some making out, which eventually led to Shin harshly shoving him on the bed and climbing on top. Not exactly an uncommon situation for Keiji to find himself in, as the other man was pretty wild during sex.

It was funny, really, how being handcuffed to the bed like this makes him feel a mix of both fear and arousal. Perhaps the running joke of Alice and Reko calling him a masochist for ‘willingly being with someone as evil as Shin’ wasn’t so far off. 

“Yeesh, and here I thought you’d be a little nice to me, considering how much of a disadvantage I’m at right now.” Shin’s hot breath tickles Keiji’s neck as he exhales at his comment. He’d love to be able to scratch it right about now. 

“Me? Nice? Now that’s funny,” Shin says as his lips get dangerously close to his neck. When they finally make contact, Keiji for some reason expects some gentle kisses. Perhaps his nerves jumbled up his brain and made him forget the odd nature of his boyfriend. Instead, Shin slowly drags his tongue up his neck. It catches him off guard, causing his whole body to shudder. 

“R-Really? You — god, you freak,” Keiji barks before he can even think. There was no concealing the crack in his composure after he stumbled over his words like that. Shin would surely have a field day teasing him for his reaction.

“Tch, how rude! What was that about being nice?” He leans back and smiles, a manic look in his eyes. There was no doubt Shin relished having power over him. It didn’t take Keiji very long to realize that even when he was the one with his hands around Shin’s neck, the teal-haired man always seemed to be in control.

“Ah, I suppose I was a being a bit mean. I didn’t intend to tease you, Keiji.” Before he can even open his mouth to call bullshit on that, Shin starts to grind his hips down against his erection. Keiji groans at the unexpected friction. In embarrassment, he turns his head away and yanks at his restraints. He wants nothing more than to pull him close and end this tortuous wait for skin-to-skin contact. He can feel those blue eyes watching him closely, remembering the time Shin described in detail the enjoyment he got from watching his muscly arms struggle when restrained.

“Ahaha, so sorry. Would you prefer me to be nice to you? Do you want me to call you a ‘good boy’, Keiji?” Shin asks, clearly amused. 

God, at this rate he might as well be the detective with all these fucking questions.

Even as Keiji feels his face heat up, he isn’t going to give in just yet. “I’m no dog, y'know,” he responds lazily.

Shin raises his eyebrow, seemingly unimpressed by his response. “Well, they’re big, dumb, and obedient. Sounds just like you!” He caresses his cheek gently, quite contrasting to his harsh insult. 

Wahaha, now I’ve got nothing witty to say to that.

As if Shin could read his mind, he finally shows mercy and crashes their lips together. The impact is rough, and the kiss ends up messy overall. If he weren't so lost in the taste of Shin, he’d probably feel stupid wondering how desperate he looks right now. The teal-haired man truly is cruel by not allowing him to grab onto his waist and explore every inch of his body. Shin leans on his knees and hovers over him, still not breaking the kiss. His hands find his face and Keiji has no choice but to tilt his head back. He’s fully aware he’s playing a dangerous game by displaying just how badly he wants the other man. Shin laughs into the kiss and gradually pulls away. Keiji instinctively chases after his lips until they are too far to reach. 

The blond doesn’t have the strength left in him to argue and is seriously contemplating begging. He highly doubts Shin can resist something like that. Fortunately, he reaches down to unbuckle Keiji’s belt before he has to bring himself down any lower. The teal-haired man makes eye contact with him, wrapping a hand around his dick. All that built-up tension finally gets to him, and he lets out a desperate sigh.

“See, all you had to do was be good and wait patiently,” Shin whispers as he holds his face with his free hand. His hand slowly moves up and down just as Keiji opens his mouth.

“Shut u-ughh,” he cuts himself off before he can embarrass himself any further. Well, Shin does always tell him he should learn when to shut his mouth for his own good. Maybe he should listen to that advice just this once.

“Aw, relax, I’ve got you,” Shin says innocently. I’ve got you? That sounds like something you’d say after saving someone from falling. However, this situation feels more like Shin is smiling wickedly right before letting him drop off a cliff. 

His hand gradually picks up speed, sending sparks of pleasure throughout his body. He starts to breathe more heavily, feeling himself shiver from the simple touch.

“Unghh…Shin,” Keiji groans as he drops his head on the shoulder of the man in front of him. Just when he thought he couldn’t look any more pathetic. When did he get like this over a fucking handjob? Keiji wishes he could say he hates the power this other man has over him, but then he’ll be just as much of a liar as Shin himself.

While still moving his hand, Shin lifts up his chin and captures his lips in a kiss. He moans into it, feeling more desperate with every intensifying moment. Suddenly, a sharp pain in his lip drags him out from the depths of his thoughts. He winces and pulls back to glare at his attacker, who smirks and smears the blood across his lip with his tongue. No matter how many times they have sex, Shin still manages to surprise him.

It feels like they’re only just getting started and Keiji already thinks he might lose his mind. He’s getting stroked even faster and won’t be able to last much longer. “Fuck, Shin I-,” Keiji stammers.

Shin whispers as he strokes his head, “You can keep going after, right?” 

How nice of him to ask. 

“Ah — yeah.” He barely gets his words out before he’s sent over the edge. His moan is low, and his whole body shudders. He squeezes his eyes shut and pants heavily as he shoots out into Shin’s hand. Riding out his final waves of pleasure, he lets himself melt into the feeling of the other man’s warm body pressed against his own. His arms no longer strain against the cuffs but rather hang in the air in defeat.

He can’t even keep up his usual calm and collected demeanor. Truthfully, it was relieving for him to give up control like this. In most situations, he felt the need to be in complete control. Letting someone else take the lead was like a weight off his shoulders. 

“You’re really trying to kill me, aren’t you?” Keiji asks through pants.

Shin grabs his chin and lifts it to meet his eyes. “Ahaha, only ‘cause I love you,” he purrs. Funny enough, it didn’t require much “detective work” to see the other man wasn’t lying. He’s looking at Keiji with more love than he’d seen all day. Or, maybe he had been looking at him like that all along. Usually, the embarrassment of it all made it difficult to meet Shin's gaze.

He kisses him once more, placing both hands on his face. This time around, it was slow and deep. Keiji can tell the other man is getting eager, as he begins grinding against him. Just like the cruel man he is, Shin breaks the kiss once more and puts on an innocent smile. He drags his fingertips along his bare chest, humming like he’s deep in thought. His unusually sharp nails graze his abs, sending a shiver down his spine.

“Hm, I almost feel bad ‘cause of that sad look on your face, but you’ll just have to watch for this part,” he tells Keiji as he crawls off his lap. He raises his eyebrow, unsure of what he’s referring to. In front of him, Shin sinks to his knees and pulls up his shirt over his head. He smirks while unbuttoning his pants, slowly pulling them off. 

After undressing himself, Shin lays on his back. Still not breaking eye contact, he knows exactly what he’s doing to Keiji. He pulls down his underwear before placing his fingers in his mouth. He pulls them out after what feels like forever to Keiji, bringing them down between his legs. 

Goddamn it.

He really is just going to make him watch as he opens himself up. His helplessness in this situation is concerningly intoxicating. Shin has him wrapped around his finger and he can’t bring himself to care. He is completely and utterly fucked.

Moving his fingers in and out of himself, Shin closes his eyes and bites down on his lip. Quiet moans escape his lips as he starts to move his fingers faster. Keiji still struggles despite how pointless it is. 

“Shin, just…just let me touch you.” He knows he won’t be able to convince him otherwise, but at least he can tell himself he tried. 

“Be quiet, or I’ll blindfold you and you won’t get to watch at all,” he huffs. He closes his mouth without a second thought. 

Well, that’s one way to shut me up quickly. 

“Ah- oh god,” Shin whined. Keiji felt his dick twitch in response to the noises he was making. He can only stare at the look of pleasure on the other man’s face as he’s working himself open. His free hand grips the bed sheets tightly as he seems to be getting closer to finishing,

But, Shin stops suddenly, announcing, “Alright, I think you’ve been waiting long enough…” He removes his fingers from himself and a quiet whimper leaves his lips. Flipping back over, he crawls his way back into his lap. Keiji has to hold his breath as he prepares for the moment he’s been waiting for. 

Shin yanks both his pants and underwear off completely in one swift movement, discarding them on the floor with the rest of their clothes. Keiji lets out a relieved chuckle as he watches carefully. Shin rolls his eyes, yet still laughs quietly too. He reaches over to the nightstand and grabs the lube, squeezing some onto his fingers. He starts to lather it on, although Keiji can tell he’s moving more hastily than before. Shin seems to notice this as well, locking eyes with him.

“God, the way you were watching me before….it was just driving me crazy. Just that look alone almost made me give in and ruin my own little game…”, he trails off, almost sounding a little embarrassed.

Keiji grins, “Wahaha, well how could I not be entranced by a show like that?” 

Shin widens his eyes a bit, clearly caught off guard by that comment. If it wasn’t for the many times he’d studied that face before, Keiji might not have noticed.

“Tch, don’t think you can get on my good side with your cheesy one-liners, Keiji,” Shin teases. Falling back into their banter once more, it takes a moment for the two to refocus on the task at hand. 

After a moment, Shin removes his hand. Keiji quickly misses his touch. He lifts himself on his knees and lines his entrance with Keiji’s dick, placing his hands on the other man’s chest to steady himself. He lowers himself down slowly, taking in a little at a time. “Ahh…f-fuck, Keiji…” Shin gets close to his ear, knowing how much his tendency to be loud turns the other man on. He finally sits down and Keiji can feel the tight, warm inside of his lover. 

They both groan at the overwhelming feeling while pressed closer together. Neither had truly allowed this kind of vulnerability to be shown to anyone but each other. 

Shin wraps his arms around Keiji, clinging onto him like he’s making sure he won’t be going anywhere. Not like he’d want to be anywhere but right here. Unable to wait any longer, Keiji thrusts up into him and earns a breathy moan. Shin throws his head back and starts to move ever so slightly. 

Without stopping, he reaches for Keiji’s hair and yanks his head back, forcing him to look up at him. He couldn’t help but groan, smirking back at Shin. They both had much more fun when things got rough.

“Don’t forget who’s calling the shots here, Keiji. You’ll get your fun when I say so,” Shin purrs, continuing to ride him slowly. 

“Ha, well-” Shin cuts him off by biting down on his neck. “Ack, you fucker…" he growls. He probably intends to leave a few marks too, just to get back for all the times Keiji had done the same. 

Shin moans before laughing at him once more. He would probably look insane to any other person, constantly snickering or grinning during sex. On the other hand, Keiji can’t get enough of it. 

“K-Keiji, you feel so good,” he whines, losing himself to pleasure. Keiji moans as the other man bounces on top of him, unable to think clearly. Shin picks up speed, chasing his climax. He starts to ramble and curse to himself as he gets closer.

“Shin-Shin…let me….” Keiji can’t even finish his sentence, yet he still understands what he is trying to get out.

“F-Fine,” Shin stutters, clinging onto him tightly. 

Keiji fucks up into him again, working to get them both over the edge. His arms ache from being restrained for so long, yet he possesses more energy than ever before. He can tell Shin is enjoying himself, as he’s moaning loudly and erratically moving up and down. He loves it when he gets like this, not concerned about how he looks and just getting lost in pleasure.

“Fuck, I can’t-“ 

He feels an intense orgasm building up once more, and seeing the teal-haired man enjoy himself so much was the last push he needed. 

Shin leans toward, placing his forehead on Keiji’s. It's a rather romantic gesture, especially when compared to all of their previous teasing and banter.

“I-I know, go ahead,” sounding like he’s getting close too. 

With those words, Keiji comes inside the other man. He clenches his cuffed fists and lets out a deep moan. His whole body shakes intensely against the embrace of Shin. 

Shin follows soon after, sent over the edge by the sight of his lover’s pleasure. Multiple high-pitched moans escape his mouth, making him go red in the face. His fast-paced movements slow down as he rides out the last of his orgasm. He lifts himself back up and sinks his body weight onto the blond, clearly all out of energy. The room falls silent and only the sounds of their heavy pants can be heard. 

“Mmm…Shin?” Keiji finally says after a beat.

It takes Shin a moment to register he was speaking before he asks, “Yeah?”

“Could you uncuff me now? My wrists are starting to hurt,” He jokes.

“Oh, aha, right,” Shin grins, using the last of his strength to free his poor boyfriend from his restraints. He tosses them on the nightstand and lays down, ready to pass out. Keiji sighs and rubs at his wrists, causing Shin to roll his eyes at his dramatics. 

“Oh, stop it. Come here,” he says as he holds his arms out. Keiji wastes no time and finally gets up from his position, laying his head on the other man’s chest. Shin strokes his hair as he listens to his heartbeat. 

“Um, I wasn’t too much, right?” Shin questions. He sometimes needed reassurance, despite how many times Keiji could tell him otherwise. The blond quietly laughs against his chest. 

“Wahaha, not exactly. If anything, you could turn it up if you’d like, give me a good slap,” He laughs a little harder, at his own joke nonetheless. 

Shin huffs, always making it too easy for Keiji to irritate him. “Ugh, we should probably clean up.”

“Mhm, sure. Just gimme a minute.”

Yeah, no one is getting up anytime soon.
