Work Text:
Five days into his new school life, Yoon Taemin gets woken up in the middle of the night by his dick. It's hard, and it's not the morning wood, ignore it and it'll go away kind of boner. No, this is so hard that it's now interrupting his sleep. He should be glad that he's got enough warning to not wake up tomorrow with a load in his pants, but it's still really annoying.
It's also unexpected, because usually he's too damn tired to be horny. After the boxing, the restaurant, the bar, the convenience store, he's too exhausted to do anything but collapse into bed and pass out, ready to start all over again the next day. Wasting time jerking off is a luxury he can't afford.
It's pathetic, but he's also not fifteen and so horny that he might die from blue balls, thank fuck.
Now that he's attending school (and just school, not even a part time job, it'd feel like luxury if this was actually his life) only his brain gets exhausted. Even in a body weaker than his own, he's got energy. Enough energy for this body he's joy-riding in to get a stiffy in the middle of the night.
Taemin stares up at the ceiling above him. Should he just ignore it? He still doesn't know where Han Siwon is. If they swap bodies again, it's gonna feel awkward as hell to know he technically jerked Siwon off, even if he was in here at the time. What if Siwon whacks off in his body? The question makes him pull a face, because shit, that's unpleasant to think about it. It feels invasive.
And there's his answer. He doesn't want Siwon to do it to him, so he's not going to do it in Siwon's body. He turns over, onto his side and shutting his eyes. Problem solved. He's just going to ignore it and go back to sleep.
Ignore how hard his cock is, straining against his pants like it's about to split the seams and burst out. How it aches, almost a physical pain that his body is telling him he can't ignore. He's going to try to anyway.
He manages about ten minutes. His body – for now it is, if he thinks about it too much he feels sick, it's easier just to accept he's here for the ride – is demanding that he does something, you fucking dumbass. It pisses him off, to lack the control he usually has, to have his body demanding stuff beyond food and sleep. Damn it, he's so horny he feels like he hasn't jerked off in months. Is it him or this body? Not that it matters, despite his big words earlier. He feels like he's going to die if he doesn't do something about how hard his dick is.
Taemin's eyes snap open, his temper flaring as he grabs his pillow to throw it, before realising the last thing he wants is that dumbass brother of Siwon's showing up if he hits something with it and it breaks. He's never had to beat the crap out of someone for mocking his boner, and he doesn't want today to be the first time. He drops the pillow and throws himself back onto the bed with frustration. Fine. It's not going away, it's driving him absolutely crazy and he's got to take care of it. He'll do his penance once this crazy mess is over.
He reaches down and sticks his hand under his waistband. It's not the first time he's felt this dick in his hand as he cups it, but until now it's been the practical, unavoidable stuff. This is the first time he's felt it hard, and it feels...a lot like his own. The way his body lights up at just a little cursory touch, is pretty much the same too. Maybe Han Siwon's dick is just a little different? Maybe a tiny bit smaller, since he's shorter and all. It's not enough of a difference that it'd cause anyone envy. It's hard to tell, though, because touching himself feels like it always does. So, technically, someone else's dick but all his response.
Fuck. Yoon Taemin, you crazy idiot, why are you even thinking about this? The plumbing is the same. What else matters? He just needs to come and then he can sleep and forget the whole thing. He doesn't mess around, switching from feeling his cock out to jerking himself off properly. Hard and fast so he can get this over with. He curls in on himself as he strokes, the shudders running through him tell him just how long it's been since he last came. Shit, he's not even doing anything fancy and it feels amazing. It's not just his mind though. It feels like this body is enjoying this too, almost separate from himself. Like it's not done so in a long time. He's feeling relief that's not just the fact Taemin is doing something about how unbearably horny he is.
Horny bitch. Slut. The insults hurled at him pop into Taemin's head and he frowns. Just insults, designed to cut someone who couldn't defend himself, or something worse? Something that'd spoil even something as harmless as this.
Life really is a bitch. But, it's all right. He'll take care of this too, he'll come and it'll be for both of them. Wow, he's a weirdo for thinking that, but he's also gonna beat the shit out of those guys when he next sees them so Han Siwon isn't going to have any complaints. Taemin shoves that thought out of his head, because even when he's this horny, those ugly mugs could make him go soft, and focuses on his cock.
The palm of his hand is softer than he's used to, his fingers unscarred by manual labour. His fist feels less rough around his cock and it's stupid but it makes him more delicate than he was to himself. Despite his promise to do this as fast as possible, Taemin slows his strokes down. His body likes it. Really, really likes it. The arousal goes all the way down to his toes and makes them curl in pleasure. When he tries teasing his slit, the pad of his thumb working it in slow circles, it's like lighting up his spine. He pushes his other hand under his waistband to join in, so he doesn't have to stop playing with the head of his cock. The pace of his other hand is slow, too, lingering strokes that are both frustrating and incredibly good.
When he feels his balls contract, it's the same as ever. Just a little more, just a bit more working and teasing of the head, just one more stroke. A gasp he has to bit back escapes as he comes, the sudden tip over from not enough to perfect, brainless pleasure hitting him like it always has. Taemin doesn't think of anything sensible, not even that he really should have got a tissue ready, as he rides out his high before sinking deeper into his bed.
That felt good. Really good. It wasn't cursory, or in a hurry because he's got five minutes before he needs to leave to not be late to work. It was pleasurable. He should probably find it weird that this body feels a little more like it's his home (for now) after coming in it, but he doesn't. Whatever. It felt good. He's got enough to worry about and this is nothing. He'll make his apologises to Han Siwon some other time.
Taemin cleans up, shuts his eyes and falls straight asleep.
