the piece (of you) i wish i had

Summary:

"You can't even take this, hyung?" Viper grins at him, his twenty-one-year-old alter ego flashing him a cruel smile full of teeth.

Dohyeon squeezes his eyes shut, biting down on his lip to stifle the moans his younger self keeps puncturing out of him. Can't even struggle with his hands helplessly pinned to the bed by the younger's strong grip—Dohyeon's never willingly gone to a gym in his whole life, but he remembers how he used to wrestle and tackle Lijie during their EDG days so of course Viper has that edge over him. And it's frankly embarrassing.

What's more embarrassing is how his twenty-one-year-old self is the one with his dick inside Dohyeon, ramming himself home with a loud smack of their skin slapping against each other every time.

How did it even get to this?

EDG Viper comes to pay BLG Viper a visit. Of course, the first thing he does is fuck the daylights out of the older version of himself.

Notes:

in honour of BLG nearly giving me an aneurysm <3

update (22/3):
in honour of BLG giving me an aneurysm and still winning fst anyway <3

"You can't even take this, hyung?" Viper grins at him, his twenty-one-year-old alter ego flashing him a cruel smile full of teeth.

Dohyeon squeezes his eyes shut, biting down on his lip to stifle the moans his younger self keeps puncturing out of him. Can't even struggle with his hands helplessly pinned to the bed by the younger's strong grip—Dohyeon's never once willingly gone to a gym in his twenty-five years of life, but he remembers how he used to wrestle and tackle Lijie during their EDG days so of course Viper has that edge over him. And it's frankly embarrassing.

What's more embarrassing is how his twenty-one-year-old self is the one with his dick inside Dohyeon, ramming himself home with a loud smack of their skin slapping against each other every time.

How did it even get to this?

That question keeps looping in Dohyeon's head the longer this goes on. From the moment Viper's cold hands began to roam around Dohyeon's soft skin, squeezing and kneeding at his flesh as if entranced by the way it gives to his touch. As if this literally isn't his own body, just five years in the future. Unless the being standing before him is a succubus, then Dohyeon has no clue why Viper would be so raptured by his own body—he definitely doesn't remember having that high of an ego.

Viper's next thrust hits the spongey spot inside Dohyeon that makes him see stars, curling his toes from the jolt of pleasure that runs down his spine. He throws his head back and without his hands to muffle the sounds escaping him, he moans unabashedly loud against his will.

"So loud," Viper snickers, leaning down to nip at Dohyeon's ear. The change in angle sends his dick deeper inside, grinding against the sensitive glands there, sending electrifying shocks through Dohyeon's delicate nerves. Viper sees this and deliberately slows down his pace, a shit-eating smirk decorating his red, kiss-bitten lips. "Hyung wants everyone to hear? Hyung wants his new teammates to know he likes getting fucked rough and raw?"

"Stop calling me th—" Dohyeon cuts himself off with an involuntary gasp, his whole body jolting from the pain of being bitten right next to his jugular. Viper's teeth sink into the sensitive skin on his neck, clamping his lips down on the patch of skin there as if he's a vampire trying to drain Dohyeon of his life source.

"Maybe they should know," Viper says darkly, returning to his earlier vicious pace, uncaring to the way Dohyeon writhes around and whimpers. "Serves you right for leaving."

Dohyeon wants to roll his eyes, but he feels like he's lacking entire autonomy over his own body. Which is an apt way to describe today's events, seeing as a clone of his younger clone suddenly appearing in the middle of the night and fucking the living daylights out of him would constitute as him losing autonomy over his own body.

The hickey Viper keeps sucking on is only one of many, Dohyeon's pale neck now a canvas for mottled purple and red bitemarks, rings of teeth that are painful just to look at. Same goes for his chest because Viper has some sick kink with lapping at Dohyeon's nipples. (Dohyeon definitely doesn't know where that comes from. He's definitely not thinking about a certain ex support of his.) Viper's not leaving a single inch of his skin unmarred, bruising fingerprints stamped on Dohyeon's waist from how hard he's gripping him with one hand while the other turns his wrists red.

Most people who were close to him back during the early years of his twenties would call him chaotic and energetic, but never cruel. In fact, he remembers both Siwoo and Tian Ye had agreed that he was a good kid if not a chaotic one. Dohyeon frankly can't remember if he was ever this horny either. Is it from the sexual repression? Dohyeon remembers that.

When people say Viper's a beast, Dohyeon's pretty sure they don't mean in bed. He was still a virgin at twenty-five for fuck's sake and he's only losing his virginity now to a younger clone of himself.

Viper starts gnawing on his skin, pulling it back with his teeth and watching with half-lidded eyes as Dohyeon cries out from the sheer pain of it. He meets Dohyeon's glare with his own dark gaze. "What? Stop thinking about other people. I'm right here."

I was not this possessive, Dohyeon hisses to his own mind. For once, he gets to bite back verbally without being interrupted. "How do you know I'm thinking about other people?"

Viper gives him a look that reads are you fucking serious which Dohyeon thinks is completely unwarranted, but then he starts fucking into him without mercy again and Dohyeon can't really do anything about it. Pulling back from Dohyeon's neck, Viper briefly lets go of his waist to grab Dohyeon's cheeks, forcing his jaw straight so that they're making eye contact when he drawls, "We're one in the same. You're thinking of Tian Ye, aren't you?"

"So you're—" Dohyeon bites back a moan, a cacophany of ah ah ahs that he knows would only stir that shit-eating grin into making a comeback. "—thinking of—ah fuck—Tian Ye?"

His efforts are fruitless. Viper's shit-eating grin returns to his face anyway.

"Are you trying to use that as leverage against me, hyung?" Viper snickers, squeezing Dohyeon's cheeks until the pads of his fingers press against the outline of his molars. Dohyeon tries flinching away, but that only makes Viper grip his jaw tighter. And where else can he go when his wrists are held tight in one hand and the rest of Viper's weight is pinning him down to the mattress? "That probably means you never got to fuck him, then?" Viper's mouth falls into a mocking oh. He cooes, feigning pity, "That's so sad for you, hyung~"

Dohyeon wants to strangle him.

He can't, of course, and isn't even allowed to indulge in the thought when Viper starts talking again. Dohyeon also doesn't remember himself being this mouthy.

Maybe it really is a succubus.

Would that make things better or worse?

(Losing his virginity to a succubus is slightly less embarrassing than losing his virginity to a younger clone of him at least. Just slightly.)

"Who did you end up fucking then? I doubt you got over cutie Tian Ye that easily," Viper says after another particularly punishing thrust that makes Dohyeon squeeze his eyes shut again. He lets go of Dohyeon's jaw to trail his fingers down the length of his neck, rubbing his thumb against the curve of his Adam's apple with just enough pressure to make Dohyeon feel it in his throat. "Siwoo-hyung? Oh, don't tell me. It's Yechan, isn't it."

Jokes on him, but Yechan's still stuck in a never-ending cycle of leaving and coming back with their ex jungler.

"Oh." Somehow, Viper takes Dohyeon's silence as its own answer. He goes still, prompting Dohyeon to reluctantly open his eyes and be greeted by the smirk on the other's face growing devilishly wide. "I'm your first, aren't I?"

Nevermind. Dohyeon closes his eyes again, inhaling deeply through his nose and exhaling out his mouth. Seungyoung once taught him a meditation technique that was quick and easy enough to do during the breaks in between games, and it feels a little like bastardising the idea, but surely Seungyong won't mind if Dohyeon tries it out in the middle of being fucked—

Viper snaps his hips against Dohyeon's slick thighs harshly, then does it again and again and again, drawing out a series of broken moans from the older man. "Stop thinking about other people—again," Viper hisses through his teeth. He doesn't sound at all threatening, but the dick hammering into Dohyeon and the suffocating presence keeping him caged to the bed keeps him from voicing that particular thought.

"You're so possessive—" Dohyeon's voice is barely above a strangled whisper, punched out of him like his weak whimpers. "—and for what?"

He gets a scoff out of Viper. "We're one in the same," he says again in that same low drawl, a mocking tone most people would easily dismiss, but Dohyeon would know his own voice better than—

Oh.

(It hits him like a blunt dagger skewered into him, or a baseball bat to the head. Dohyeon doesn't know what to feel about it, but he knows that it's a painful, sinking feeling.)

"Who would know you better than I do?" Viper murmurs against the column of Dohyeon's throat, the words stamped across his marred skin. "Who could reciprocate your feelings better than I do? I'm sure you remember your particular obsession with Deft back when you were my age. Five years later, you're still the same, aren't you?"

Dohyeon bites his lip. Doesn't want to admit it.

Not that he still has an immature obsession with Deft—that would be more than shameful—but Viper's right about one thing. One thing that no one's ever really clocked him for. Wangho always had that look in his eyes, but he knew better than to voice it, so Dohyeon could've stayed forever blissfully ignorant of his own desires had it not been thrown in his face just now.

It's simple. Dohyeon's not used to getting what he wants because he never asks for it. He's content with what he's already been given, content with watching from afar, content with blurred lines and undefined relationships. In a way, it's also a preventive measure. If he never had it to begin with, how can he end up losing it?

(...Maybe he can see why Yechan and Lijie are stuck in their ouroboros cycle.)

Viper licks a long stripe down the curve of his throat, his teeth catching at Dohyeon's flimsy skin, almost teasingly. Without warning, both his hands go to Dohyeon's waist and flip him onto his stomach with his dick still inside, the change in position making Dohyeon swallow back vomit. He forces Dohyeon's head down, muffling his guttural moans with a pillow, and keeps Dohyeon's hands pinned behind his back. Like this, all Dohyeon can do is lay there and take it, crying into the soft pillow. But it only makes it worse when all he can smell is the heady scent of sweat and sex. His room is usually lathered with soft and sweet scents from his diffuser and aromatherapy sticks, so he's overwhelmed by Viper's powerful musk.

It's not the bad kind of overwhelming.

Dohyeon feels like a rabbit held by its leg, caught in a trap, helples to whatever predator decides to turn him into their next meal or decoration, but really, he's not fooling anyone that was here to witness the showdown between him and his younger clone. He was the one whose eyes jumped to the other's lower region first. He didn't fight back when Viper grabbed him by the neck and kissed him senseless, or when Viper tore his clothes off and pushed him down onto the bed. He's a willing victim. The most willing.

"No wonder you're so fucking tight," Viper scoffs, rutting his hips against him like a wild animal. Their bodies entwined like mating snakes, fangs pointed at each other and locked in a desperate embrace. For when you think about it, a bite can count as a kiss too. "I could practically feel your guts stretching to accomodate just one of my fingers."

"Shut up," Dohyeon tries to whine into the sheets, but it only ends up sounding unintelligible even to his own ears. Was he really like this? Was he ever this into dirty talk?

Doesn't matter. Can't Viper just keep his fucking mouth shut?

"You don't actually want me to shut up," Viper abruptly says, and Dohyeon's hit with the dread that the other man can read his mind—which, granted, he should've seen that coming from the start. Clone telepathy. Yup. "You like this, hyung~"

Embarrassingly, a full-body shiver runs through Dohyeon. Viper obviously doesn't miss it, snickering like a deranged clown while mercilessly grinding against Dohyeon's prostate. Slick fingers grab a fistful of his hair, pulling his head back until his mouth hangs open uselessly.

"Do you want me to call you gēgē too?" Viper teases dangerously.

But now that Dohyeon has free rein over his mouth, he turns his head back slightly to glare at Viper when he retorts, "If that helps you think of me as Tian Ye."

Viper rolls his eyes, moving his grip to his jaw and silencing him with a kiss, smearing Dohyeon's words and the rest of his resolve all over his lips. Beyond the taste of sweat, there's a faint hint of peach soda Dohyeon remembers intimately of. He used to love that particular brand of peach soda, bought it every day that the managers at EDG had a personal supply for him in the practise room refrigerators. Tasting that on Viper's tongue throws him back four years into the past.

A big part of Dohyeon won't ever get over 2021. He can still feel the visage of glory at his fingertips, warm arms engulfing him in cherished hugs, the line between teammates and family going blurry. Their base and dorm building, that noodle restaurant; places that will forever hold those beloved pieces of his youth.

And Viper still gets to live in those memories.

In some bastardised version of yearning, Dohyeon hopes Viper won't immediately disappear once he gets his fill.

He's not sure how it works, but maybe if he makes Viper keep wanting more, then maybe he'll stay—and maybe Dohyeon will get to keep a piece of those treasured memories with him forever.

Dohyeon almost forgets that they're still kissing until Viper pulls them apart for air, cursing under his breath about how he's close. Dohyeon drops his head against the pillow, lets Viper fuck him until he comes, too dissociated from reality to realise that his dick squished between him and the bed already went limp from post-release sometime ago. He's twitching from the overstimulation, but the sensation is distant. Somehow, the past seems closer than the present.

A couple rough thrusts later, warm liquid fills Dohyeon up to the bim, Viper collapsing on top of him like a ragdoll.

"I'm not leaving anytime soon," Viper says quietly after several long moments of silence passes between them, sounding reluctant to even voice it out loud. "When I do leave, I'll bring a friend with me next time I visit."

Dohyeon lets his eyes close on their own, blinking back the sleep threatening to pull him under. His chest rises and falls with the rhythm of his lungs yearning for an air more intimate than oxygen. The kind that can be perceived by all five senses. An 'oxygen' that sounds like joyful laughter, feels like summer-warm hugs, and tastes like peach soda.

"Can you get off me now?"
