Chapter Text
He wakes up as Jimin again.
It’s highly inconvenient.
It’s happened before a few times, that they randomly switched bodies overnight with each other. They’ve always been able to switch back in a day, but it’s been two days now.
The others don’t know about it, so they decided to keep it a secret since it’s absolutely unexplainable why and how it happens.
But now, it’s a little bit of a problem.
“Can you find anything about it?”
Jimin asks, looking at himself in the mirror.
Jeongguk sighs, looks at Jimin, at his own body. It’s quite weird to see himself from Jimin’s perspective. He looks taller, for some reason more handsome than how he sees himself.
They haven’t figured out how it works anyway, if it’s even both of them being able to do it, maybe just one of them, or if it just happens by chance. Maybe some fucked up alternate universe paradox.
“No, I mean, no one on earth has this problem, it’s not like we’re just going to find a cure on Google. The only hope I have comes from fantasy books.”
“You’ve got anything from that?”
“No.”
He lies, ears burning up.
He’s read multiple times that sex is a common way to swap back. Sometimes just a kiss will do. But he doesn’t dare bring it up, it would make things awkward between them. They’re just good friends..
though he’d like a little more.
He’ll never tell Jimin that though.
“So, we’re just going to wait then? Pretend we’re each other until we swap back?”
“I think that’s the best course of action. I mean, last times it happened we switched back after a day or so right? It’s only been 2 days.”
Only..
Jimin looks at him with doubt, but then shrugs.
“Sure. Let’s try that.”
———————
It’s been a week.
They haven’t swapped back. It’s getting a bit more worrying now.
Miraculously, no one really notices it. After all, they’ve lived together for a long time, they know each other very well. But it gets tiring for both of them. They can’t do what they want to do, can’t talk to the people they want to talk to, can’t go places with family or friends.
And maybe this is just his own problem, but he can’t touch himself.
Because it wouldn’t be touching himself, it would be touching Jimin’s body. And that’s weird.
But after a week of not jerking off while usually doing it twice a day, it gets to him. He’s done his absolute best not to look at anything when he takes a shower, not to invade Jimin’s privacy. But there are things that happen that he just can’t ignore.
When he washes himself under the shower and brushes over one of his nipples, his cock twitches. He’s never had that himself, his own nipples aren’t sensitive, but apparently Jimin’s are.
It makes him blush profusely.
He does not need to know these things about his best friend. Just like when he watches a series and two guys kiss on screen and his cock twitches.
Though he’s always suspected Jimin to like guys, he did not need to find out like this. He stays half-hard for long as well, and at some point he just can’t help it.
Is it weird to be curious?
They joke about it all the time, who has the biggest and smallest. They joke about Jimin having a small dick, but whenever he feels it twitch it’s.. it’s kind of heavy.
And it’s not like he’d do something to Jimin’s body, so it shouldn’t matter to take a quick look at it. He’s sure Jimin has done it too by now. He must have. Right?
His cheeks burn when he stands up, walks to the full length mirror in the corner of the room.
Jimin’s body, his eyes, nose, lips, they’re all so doll-like, so pretty. He takes off his shirt, looks at the nevermind tattoo inked on his ribcage, brushes his fingers over it. always liked this one the most.
When he reaches the last letter, his eyes accidentally drag up to his nipple. Jimin’s are darker than his own, and they’re sensitive. He catches his bottom lip between his teeth, stares at his reflection, guilt rushes through his veins when he brushes a finger over one of them.
“Mmh.”
Fuck, yeah, they’re sensitive. Established that, shouldn’t touch it any longer. This is not his body. Not his to play with.
He watches his small hand, rubs his nipple between his index and thumb, the sensation surges through his veins, he can’t bring himself to stop. When he looks up, his eyes are glazed over, lips bitten red, cheeks flushed.
Fuck.
Jimin looks so pretty when he’s turned on.
His cock twitches as he keeps rubbing over his nipple. It catches his attention, eyes traveling down to his crotch. It slowly grows hard in his sweatpants, tenting in the fabric under a minute.
Fuck, he shouldn’t. He shouldn’t do this, he’s breaching every line there is.
Curiosity takes the better of him, and he hooks his fingers into his sweatpants and boxers, pulls them down over his hips, lets them drop to his ankles.
He closes his eyes for the first few seconds, hates that he can’t stop. Jimin would scold him so much, would be so embarrassed if he knew what he was doing to his body.
When the initial shock passes, he looks at Jimin’s half-hard cock. It’s pretty, shaven. Not as small as they always joke about. And he’s not even fully hard.
He swallows.
Well, he’s seen it now. Curiosity has been fed. He can just let it go now, pull his pants back up and never think about it again. But he just stands there, marvels at Jimin’s body, still playing with his nipple.
In a way, he’s just taking care of him really.
In a way he’s just making sure Jimin’s body stays healthy while he’s in it.
Touching yourself is good for your health. And since Jimin can’t touch himself, Jeongguk is just doing it for him.
For his health.
He leans in a little closer to the mirror, examines Jimin’s pretty face, touches his lips, wets them with his tongue.
Fuck, he’s hot.
He dips one of his fingers in his mouth, sucks on it, obsessed with the way those plump lips wrap around it.
it’s obscene.
He’s got a really good mouth. Such a good mouth. He pushes another finger in, tests how deep he can go, for no particular reason.
He slowly thrusts in deeper, cheeks burning up, eyes stinging a little with tears.
Jimin would look so good taking cock.
He shakes his head, shouldn’t play with Jimin’s body like this. said it’s only for his health, but what he’s doing now has got nothing to do with that.
So he pulls his fingers out of his mouth, but his dick twitches when he looks at the string of saliva still attached to his lip.
Fuck..
His eyes drag down again, that pretty cock now standing up straight against his stomach.
He slowly curls a hand around it.
It’s definitely not small. He’s got a good length, and it’s quite thick, a nice girth. His small hand can almost not close around it.
Ah, he shouldn’t be doing this, it’s not ethical, he’s breaking Jimin’s trust, his privacy.
He bites on his lower lip, strokes himself once, slowly.
“Ah..”
Sensitive. He loosens his grip a little bit, slowly pulls down the foreskin, looks at the head of his cock, all flushed.
Fuck, Jimin really is pretty everywhere. He’s thought so many times that he’s charming, but he’s also shaped perfectly. With his mouth slightly agape, he rubs his two wet fingers over the head of his cock, sucks in a sharp breath.
It needs to be wetter.
He spits in his hand, then coats his cock in it, ears burning with shame. Getting off in Jimin’s body feels so different, he’s sensitive in different places, feels pleasure differently.
Usually, in his own body, he feels it in the pit of his stomach. But when he tugs on his cock, he can feel heat flare up his chest and neck, his balls tighten.
When he cups his balls he feels pleasure run down his spine, a quite loud moan escaping his lips. He clasps his hand over his mouth, looks at himself in the mirror.
So, Jimin is loud.
He takes a deep breath, gently touches his balls this time around. He can play with his own as much as he likes, they don’t feel quite as sensitive as Jimin’s. One gentle tug and he feels like he could burst.
Compared to how long it takes to get himself off, Jimin seems to not need longer than 5 minutes. He’s just a little jealous of how sensitive Jimin’s body is. Wants to know what else new there is to discover, where else he’s sensitive.
When he dips his finger between his cheeks, it doesn’t surprise him how he arches into the touch. It doesn’t surprise him when his cock twitches in his hand as he presses a finger against his rim.
Would Jimin finger himself?
He swallows as he takes small shameful steps back towards the bed, mind racing as he thinks of that one drawer of the nightstand that Jimin told him not to look into.
He can’t help himself.
Already breached all his privacy anyway, what’s another little thing?
He crawls onto the bed, peeks into the drawer, finds what he already thought would be there. Lube, condoms, tissues, and a realistic dildo.
Fuck.
The thought of Jimin fucking himself is.. it’s driving him insane.
He’s never felt the need to touch himself like this, but when he rubs over his rim he can feel his body aching for it. Like he’s made for it.
He needs to know. what it feels when he fingers himself, when he fucks himself.
So he grabs the lube, the dildo, can’t believe he’s actually doing this but he is. He can’t turn back anymore, he’s already gone too far.
He coats his fingers in lube, keeps his eyes on himself in the mirror from the edge of the bed, grabs one of his cheeks and exposes his rim.
He gasps, feels all types of wrong when he rubs his lubed up finger over his rim, watches himself do it.
It feels so good, so familiar. When he pushes a finger inside, it’s like he was waiting for this. Like his body craves this touch like it’s a routine he’s gotten used to. It feels just as good as the hand around his cock.
“Fuck-“
He watches with lust-glazed eyes how his finger easily slides in and out, made to take it.
The longer he watches the more he wants to push that dildo in already, impatient to see how it will fit inside of him, to feel what it’s like.
But he fingers himself thoroughly first, watches his every move. God, Jimin is flexible, can put his leg so far up, doesn’t hurt a bit. He makes a show out of it, fucks his fingers inside of himself, spreads his legs wide. He loves clenching around them, body running hot.
And then he finally takes the dildo, coats it in lube quickly, no wasting time, though he needs to be careful with Jimin’s body.
He thinks.
Does he?
Is Jimin usually careful with it when he rubs the dildo against his rim? Does he finger himself thoroughly? Or does he have no patience at all, does he just fuck himself after the second finger, does he like the feeling of his rim stretching around the silicone..
He bites back a moan, watches the dildo in the mirror, pushes the head slowly past his rim.
“Fuck- fuck-“
He doesn’t know if it’s the feeling or the sight that’s better, but both send him to heaven. The way his hole sucks in the dildo looks mesmerising.
What he would give to fuck Jimin himself.
It’s dark for a second, as if someone turned off the light switch—
Oh fuck, this only happens when they switch bodies.
A second later, he’s in his own room. One hand around his cock, one hand around a phone, recording it.
He blinks once, twice, tries to adjust to his surroundings but he’s so—
Damn, he’s so close.
“Oh..”
Heat rushes up to his face, he keeps stroking himself, completely disorientated, looks at his dick through the camera and it only now clicks.
This is Jimin’s phone.
Jimin was just in his body filming this. Recording him getting off.
Wow.
He takes a few deep breaths, should probably stop but that heat in the pit of his stomach is dizzying, and the idea that Jimin was doing something quite similar sets him on fire.
“Fuck—“
He bites his lip, moves the camera a little closer for Jimin, catches how he jerks off, that hot, wet sound each time the foreskin rubs over the head.
If Jimin wants to see this he’ll give it to him. Rubs his thumb over the slit, coats it in precum, and runs it down his length.
In the bottom left corner of Jimin’s phone he can see the most recent picture, another dick pic— Jesus Christ.
Did Jimin just— create an entire folder for himself? Has he been taking pics and videos for when they switch back, so he can get off on this?
His eyes roll back, low moan rumbling through his chest as he nears his climax.
It’s hard to keep filming, but he fucks his hand harder, tilts the camera so it captures his torso as well, and then with a few more strokes all of his muscles clench, that pleasure in his gut spreads through his veins, and cum shoots over his stomach and chest in slick, white ropes.
“Fuck— Jimin..”
He groans, that sight of that dildo pushing inside burned on his retina. Sweat drips down his temple as he strokes himself through it, the arm holding his phone up trembling a little.
He brings it down, captures the slow, last strokes, the last bit of cum seeping from the head, dribbling down his length.
Then he pans the camera to his face.
“Hope you liked that.”
He breathes out, can’t help the small smirk that appears on his lips before he stops the recording.
It’s gonna be so fun giving his phone back to him.
————————
fuck— he’s gonna hate himself for this later. but after all the pictures he already took— what’s a little video anyway? As long as Jeongguk doesn’t find out it’s fine, and he’s so horny— it’s impossible not to.
ever since they swapped bodies the first time, he’s been way too curious. Jeongguk has always been so handsome, so even though they agreed not to look or touch their bodies in weird ways, he broke that rule the first time it happened.
Jeongguk’s body is so healthy, so strong, he’s tall, he’s broad, and he’s hung.
He only took a good look the first time, to quench his curiosity.
The second time, however, it was an accident really; he was watching a series on his phone, and when the protagonist and love interest kissed, his dick twitched.
Usually, his own body, it’s not that reactive, but Jeongguk’s body is different. Maybe it’s because he’s a late-bloomer, or maybe it’s because he’s a bit younger, but he gets hard from anything.
The brush of his hand, his pants being too tight or too loose, simple kisses on tv, the wind.
So, eventually, he couldn’t help it, he looked.
That was really the beginning of it all.
The sight of Jeongguk’s hard cock, so pretty against his toned stomach.
His years long unanswered crush was finally starting to go away, only for the universe to throw him an uno reverse card, waking up in Jeongguk’s body.
And now; well..
Some good dick pics of Jeongguk for his stash.. it’s unethical, yes, but after years of fantasising about what it would be like, he just wants a little something for himself.
So a recording.. it’s not that bad, right? Pictures are hot, but a video— he could treasure it for years, his secret folder, for when he’s really desperate.
He bites his lip, jerks off a little faster, loves the feeling of it in his hands, so thick— so hard.
What he would give to just.. ride it once.
The light switches off. He looks around but everything is black.
Oh no.
Oh fuck no.
This only happens when—
He blinks, and his surroundings change, suddenly he’s in his own room, looking at himself in the mirror.
Shit they really had to switch back now?
What is Jeongguk gonna think? Fuck, how can he even excuse what he was doing? What is—
..
There is a dildo halfway up his ass.
He’s holding it, he’s literally looking right at it in the mirror.
If they just switched..
Then.. Jeongguk was doing this to his body just now.
Jeongguk did this to him.
Heat rushes up to his cheeks— because not only is he fucking himself, but he’s sprawled out in front of the mirror, completely naked, watching himself, watching the dildo push inside.
Of all times he’s fucked himself he’s never once looked in the mirror, but Jeongguk— fuck.
The thought of Jeongguk using his body this way sets him on fire. His dick twitches against his stomach, and instead of rushing to Jeongguk’s room to confiscate his phone, he just pushes the dildo in all the way.
In comparison, he knows what he was doing is probably worse, but still, they’re both clearly past the rule of not touching.
So he pushes the thought aside for a while and just fucks himself with the dildo. Done it so many times it feels familiar, loves the shape of it, always grazes his prostate just right when he pushes it in.
And.. if Jeongguk was doing this to him then.. maybe the concept of them fucking could become a reality..
Right?
He hopes so.
Hopes Jeongguk was thinking about it when he pushed the head past his rim..
The image of Jeongguk’s dick is still fresh in his mind, and naturally, he imagines that’s what he’s sinking down on right now. That pretty, big dick, nice and hard, with that flushed, wet cockhead—
“Nngh..”
He curls his hand around his dick, jerks off as he thrusts the dildo in harder.
Too bad he couldn’t get to see that cumshot. Wished their bodies hadn’t switched back in the middle of it— maybe then he could have.. tasted it on his tongue, Jeongguk’s cum.
“Ah.”
Heat coils in his gut, and he wonders how long Jeongguk had been playing with his body before they switched, because his nipples feel a little sensitive too.
God fuck..
Part of him wishes Jeongguk would just walk in right now, come and see what he’s doing with himself— that he’s finishing what he started.
Another part of him is wallowing in shame knowing the state in which Jeongguk came back into his body.
The stash of dick pics in his phone.. the recording.
It’s all going to be deleted.
He bites his lower lip, eyes fluttering shut, his stomach muscles contracting, hole clenching around his dildo.
Jeongguk’s dick is bigger.
His ears burn up as he pushes the dildo in deeper, to replicate what it would feel like, a bigger dick pushing in.
How would Jeongguk take him?
maybe hard and fast as a punishment for what he did..
He swallows, pulls the dildo almost all the way out, then rams it back in.
“Ah— Jeongguk.. sorry..” He moans, but doesn’t stop, pushes the dildo in harder, faster, until the wet smacking sound fills the room. “Nngh—“
Pleasure builds up in his gut, and he flicks his wrist a little harder even though he doesn’t deserve it yet— but oh— he’s gonna come. His toes curl, and he moves back on the dildo erratically, chases his high until all that pleasure bursts, and cum shoots from the head of his cock, lands on his stomach, slick and sticky.
“Ahh fuck.” He groans, jerks himself through his orgasm, rides the dildo slowly until the pleasure settles. “Mmh..”
He pants, looks at the ceiling, pure satisfaction running through his veins.
It’s only after he pulls the dildo out, and wipes the cum off his stomach, that he realises he’s going to have to ask his phone back.
——————————
Oh it’s one of the worst moments of his life.
He’s done everything in his power to delay this moment from coming, but at some point it’s inevitable, he needs his phone back.
It feels like a walk of shame to Jeongguk’s room. Even though Jeongguk was doing a similar thing to his body before they switched back— documenting everything is just a little bit worse. Just by a tad or so.
He’s sweating when he knocks, throat already tight.
Jeongguk opens the door, and instead of shock or anything along those lines, he just sizes him up slowly, the smallest smug smile curling on his lips.
Fuck.
He keeps his head high.
“You.. still have my phone.”
Right? Not addressing it is better. Skipping over the whole: we touched ourselves in each other’s body
“I do.” Jeongguk looks over his shoulder, as if it’s somewhere back there, but doesn’t go get it. Instead he turns back, leans against his doorframe. “Want it back?”
Oh. He’s not just letting him have it..
Heat slowly creeps up his neck. The look Jeongguk gives him; so knowing. It’s embarrassing.
“Yes I want it back.”
He averts his gaze, anything to avoid the way Jeongguk stares at him.
Nothing is worse than this.
He’s been taking pics and videos of Jeongguk’s dick— on the very phone he’s asking back right now. Of course Jeongguk is all smug about it. Even though he shouldn’t be. Jeongguk was putting a dildo up his ass for god’s sake— he is just as bad.
And yet.
When he looks back up, Jeongguk just hums, a glint in his eyes, runs his tongue over his lower lip piercings.
“Fine.”
Jimin just stands there as Jeongguk goes to get it.
There’s nothing clever he can say, nothing comes to mind— he doesn’t want to ask either, it’s too embarrassing. Because for all he knows, Jeongguk was just horny that time, playing with his body because he’d been stuck in it for a week.
But he— he recorded it. So Jeongguk knows that he’s interested, that he likes guys, that he would fuck him if he had the chance.
So, Jeongguk walks back with his phone in his hand, stares him down all the way with that twinkle in his eyes. Doesn’t even have to say anything, everything just screams: I know what you did, I know what’s on your phone
He gets his phone planted in his hand, Jeongguk’s fingers brush against his.
He clears his throat, quickly puts his phone in his pocket, wouldn’t be surprised if he was bright red.
“See you at practice later.”
“Mmh.” Jeongguk nods slowly. “Have fun.”
Have—
Have fun?
The tips of his ears burn, and he quickly turns, doesn’t grant Jeongguk the satisfaction of his expression, just quickly scurries down the hall to his own room.
Ah, this is a nightmare.
He already had a hard time without Jeongguk knowing about his crush— and now Jeongguk is fully aware, even teasing him.
How is he going to survive any of that?
He’s out of breath when he slumps down on his bed, takes out his phone right away like a habit, the screen lights up—
“Oh my fucking god—“
He throws it on the bed, but it’s still staring at him.
Jeongguk’s dick.
It’s his screensaver.
The pic he made, right there.
Jesus fucking—
He quickly grabs it, opens his phone, goes to his gallery— everything is gone. All the dickpics he made, the video, it’s all gone.
Well, of course it is, why would Jeongguk just let him have that? Not only is it a complete invasion of privacy, but it’s also just way too risky to have that.
But.. ah.. that video.
He hovers his thumb over his deleted folder, clicks it shamelessly. They’re not there either.
As if Jeongguk wouldn’t check.
It’s fine. He didn’t have the right to have them anyway.
Except his screensaver.
He locks his phone, looks at it again. The length of Jeongguk’s cock takes up the entire screen, the vein along underside of it visible, head of his cock flushed, pretty.
He takes a screenshot with burning cheeks, if that’s all he can have he’ll take it. and then he quickly changes the background to an unassuming default picture.
Nothing to see here.
———————
Dance practice is awkward when you’ve swapped bodies and played with your band member’s dick and also filmed it. A concept, he supposes, uncommon to normal people.
To him, a sad sad reality.
Especially when Jeongguk wears those loose sweats where everything kind of just dangles.
Is he not wearing underwear?
Forgive him for looking.
It’s been a week of radio silence, they haven’t swapped bodies, they haven’t talked. Jeongguk is just insistent on staring at him with that smug little smile from across the room.
As if he didn’t play with his body as well, as if he wasn’t fucking himself with a dildo in front of a mirror before they swapped back.
It gets to a point where he just can’t take it anymore.
“Can you stop staring at me like that?”
He asks after everyone’s left the practice room.
Jeongguk drinks from his water bottle, sweat still glistening on his skin, from his face to his neck, black hair sticking to his face at the ends, those dark brown eyes catching his own.
He’s pretty.
Jeongguk brings the bottle back down, that sleeve tattoo on display.
“Like what?”
“You know what I mean.”
“Oh.”Jeongguk tilts his head. “Like you took pictures and videos of my dick when you were in my body?”
Fuck.
He quickly looks at the door— still fucking open, immediately goes to close it. When he looks over his shoulder Jeongguk just gives him that same insufferable smirk.
“Did you like your screensaver, hyung?”
This guy.
He bites his tongue, tips of his ears burning, a flash of Jeongguk’s dick on his retina.
“You were playing with my body too.”
He tries to keep his voice down.
Jeongguk just huffs out a soft breath, shrugs.
“Yeah, but I wasn’t filming it.”
“No, you were just watching.” He reminds him. “In the mirror.”
“You were stashing pictures of my dick. Jerking off on camera, to watch later.”
Shit.
He’s definitely worse.
Jeongguk knows it too, just gives him that long stare, that: tell me I’m wrong
And well, he’s not.
“I— I just like filming myself— but I happened to be in your body. I was gonna delete all of it but we switched back in the middle.”
Excuse of the century.
“Sure.”Jeongguk chuckles, then walks over to the bench and grabs his sweater. “You were not keeping that for later at all.”
“I would— I wouldn’t do that. I’m not like that.”
He’s so like that, but he has a smidge of hope that Jeongguk might have some faith in him.
Jeongguk pulls his sweater over his head, looks at him right after, hair a little messy, playing with those pretty silver lip piercings with his tongue.
God, he’s hot lately.
Should have filmed that instead.
“Yeah, would you have deleted them if I hadn’t already?”
Jeongguk asks.
“Yes. It’s the filming itself that’s a turn on, but I wouldn’t just keep that on my phone.” He’s so desperate for Jeongguk to believe it, anything to make it more bearable. “I— I do that in my own body too, just— film it and delete it.”
“Mm.” Jeongguk looks like he doesn’t believe a second of it, gives another slow nod. “Right.”
Fuck.
He can’t lay it on any thicker, can’t say anything else. His entire body is burning with the lies, never really been too good at it.
Jeongguk walks up to him slowly, taller than him despite it only being a few centimeters, that small smirk grows on his lips, and then he just walks past him.
“They’re in your hidden folder.”
Jimin blinks, the words only make sense when the sound of the door closing behind Jeongguk echoes through the room.
