Work Text:

But I feel something inside of me
It's running deep I don't know
What it is, but I'm pretty sure
I better keep it hypothetical

Vegas had, truly, in his opinion, been on his best behavior last night when he happened to find his cousin Kim getting absolutely shitfaced at the same bar he was at. It would have been so easy to bother him, to get in his head, maybe find out why he was downing the alcohol anyways. 

Instead he’d kept his distance and watched as the bartender hailed him a cab and sent him off his way. This morning, however, was an entirely different game. 

Maybe his reasoning was to at least make sure the man hadn’t died, maybe he had an agenda, or maybe he was just too damn curious to turn away. Something had him sneaking in at the early morning hours just to check in on his favorite cousin. 

The sight he’s greeted with upon entering the bedroom was an unexpected delight. Vegas bites his lip, that serrated knife of forbidden curiosity twisting itself somewhere near his groin, body starting to warm up instantly. 

Kim was laying there, sprawled out like an offering, one leg bent at the knee, laying him open. Vegas almost would laugh at the haphazard way he’s got his pants hanging off the lowest part of his calf on the other side, as if the effort to undress was too much and he’d just passed out like that. He would laugh, but his eyes are too busy greedily drinking in every exposed inch of golden skin. His mouth waters. A familiar surge of aroused adrenaline kicks in. 

Kim hadn’t woken up in the slightest yet, just groaning a little in his own slumber, one hand scrubbing over his eyes clumsily while the other remained pressed high into the pillow above his head, stretching his arm in the most convenient way to allow his naked chest to be revealed.

“Well don’t you look delicious served up on a platter for me like this…” Vegas practically purrs. Kim still doesn't stir. Can Vegas really be blamed for this further indulgence of his curiosity? His lower body now comes fully to life, aching in his pants the longer he looks at his cousin just on display like this. 

Kim was so fucking handsome and yet also, so pretty. Vegas had wanted to play with him for a long time, but his cousin was too morally aligned to let that happen. Maybe now was his chance…

Glancing around, he finds exactly what he needs. “Oh baby, you’re making this too easy for me…” Vegas taunts with growing delight, strolling around the room to the other side where a robe was conveniently hung on the back of the door. He tugs the sash out from the loops and comes back over to where Kim was, somehow, still asleep. 

His movements were quick, effective, years of practice in the art of tying someone up serving as his advantage. This was the first time his captive would be enjoying his torture just as much though. 

After tying up both wrists and then attaching them to the bedpost, Kim now lays there with his arms high above his head. He does make a slight noise now, eyebrow furrowing in pained confusion. The hangover would be more brutal than Vegas’ plan of attack, probably. 

Vegas pats him on the cheek with a slow grin. “Good boy.” His smirk was dark. It’s all fun and games to him, especially now. Having his cousin bound meant he could explore, view, touch

He doesn’t hesitate to indulge now, eyes raking over slowly, appreciating the way he can see Kim’s pulse quicken in his throat. Vegas presses his hand against it, wanting to feel the sensation. 

His gaze travels down lower, watching how the muscles in Kim’s abdomen start to twitch as if knowing there’s attention there, subconsciously. Another groan, sounding like Kim was starting to be a lot more awake as Vegas just keeps roaming his skin…

That’s when Vegas sees it; standing proudly as a testament to how much, at least physically, this treatment was enjoyable. 

Kim was hard. 

Vegas smirks with pride. Whiskey dick didn’t stand a chance against his powers, it seems. He’s got a mission now for sure, crawling to place himself astride his cousin’s thighs. “Well look at you…someone must be having a damn good dream.” He croons, leaning in to whisper in Kim’s ears, attempting to get even more of a reaction. 

“Why don’t you wake up and tell me all about it, hm?” as he’s teasing him, his hand slides down pointedly, beginning to palm at the bulge over the fabric of Kim’s strained boxers. 

 

Vegas’ voice and sudden touch seems to do the trick. Senses going on high alert despite fighting the heaviness he can surely feel everywhere, Kim jolts awake with a gasp. 

Eyes flying open, he instinctively tries to tug on the restraints, wincing when he realizes he’s got no use of his arms. “Vegas…?” Kim croaks. As if delayed, he fully registers now the hand rubbing at his clothed cock. “What the fuck?!” Kim starts to thrash now, anything to get away, but he’s only slowly coming to the realization of just how trapped he was. Shit. 

His head was still throbbing from the alcohol last night, everything was a little blurry, but his cousin was on top of him and his hand was now slipping into his boxers. 

“Stop. What are you…ah.” Kim can’t even speak past the genuinely welcome feeling of a hand around him. He cuts himself off with a betraying moan, eyes flickering away from his cousin and his smug face that would surely turn into a smirk from knowing he caused that. 

“You don’t want me to stop.” Vegas accuses, voice sharp like a razor edge cutting right to the point. Kim would rather die than admit it though. 

“Fuck you.” He spits, groaning at the way it makes Vegas tighten his grip. 

“Is that any way to talk to the person saving you from pathetically chaffing yourself in desperation this morning?” Vegas taunts, not missing a beat. “Besides, I want to know who you were dreaming about.” He leans forward, grinning, hand only moving torturously slow over Kim’s length. 

“Who says I was…?” Kim tries, the words coming out on a heated gasp as Vegas swipes his thumb over his swollen head. 

The sneer on Vegas’ face shouldn’t look this attractive. “Your dick had a lot to say about that, actually.” he counters, glancing down again. “Getting all excited despite being doused with alcohol all night.” He leans in, his face inches away from Kim’s own, breathing harshly as his gaze lingers on his cousin’s lips. “Who was it?” 

“Fuck…” Kim gasps, vision beginning to swim. He’s aching, pining, wanting more things than he can voice right now, even though Vegas was kind enough to let him remain ungagged. Admittedly, that was a little bit of a surprise, considering he’s dealing with a sadist. He rips his head away before the idea of closing that gap got even more treacherously enticing. 

After a moment, Vegas laughs, dark and sinister. “Tell me, sweet cousin, and I’ll let you cum.” The threat was a death blow, knocking all the remaining air out of Kim’s lungs and making him feel winded. He swallows, strains against the bindings on his wrists. In any other situation he could get out of them, but not when Vegas was the one making the knots. Kim sighs, giving up on wasting his energy. 

“What if I said it was you?” He challenges, using the only weapon he had left. It didn’t matter if there was truth to the words or not, he needed Vegas to believe there was…

Vegas just tuts, but the flash across his features was a combination of emotions that screamed his own vulnerability, if only for just a moment. “You’re just telling me what I want to hear.” Kim knows him well enough to recognize the fact that he was, surprisingly, hopeful about this being true. 

Kim had run the hypotheticals in his mind before. It wasn’t just about being cousins, though that was a large part of why it was ‘wrong’. It was more about the fact that he knew how dangerous giving Vegas this power was, and he knew how addicted he might become to letting him have it. 

“So what if I am?” Kim, finally, manages to smirk back at him. There’s danger dancing in the look between them right now, as if they’re on the precipice of a much bigger cliff than either can realize. 

Accepting his farce, Vegas grins back, giving another torturous squeeze around Kim’s cock. “Perfect. Works for me.” He starts to stroke a little more now, allowing the friction to happen naturally instead of cutting it off to drag the pleasure out. Kim appreciates it even as his mind goes blissfully blank. 

Somehow Kim knew he’d end up here one day, being mercilessly tortured by his cousin for the sake of his own twisted pleasure. What he didn’t expect, though, was to also be getting off on it.

“You get a reward for that.” Vegas chimes suddenly, sliding down Kim’s body. Before he could even register what his cousin was about to do, there’s lips on his skin, trailing down. “Vegas, please don’t…” Kim hisses air through his teeth as the man goes on, undeterred in the slightest. 

“I love when you beg, baby.” He croons in a low hum, just reaching his target now as he takes Kim’s length into his mouth eagerly with an obscene hum.

Fuck….Vegas…” He should be mad, should be cursing Vegas’ name at being accosted like this, not shouting it in the throes of desperation. What a fucked up twist of fate this was. 

It doesn’t take much. He’d been straining, dying for release since the first languid stroke had begun. At the sensation of a hot mouth enclosing around his throbbing cock, Kim had damn near cum on the spot. Once Vegas actually starts to suck him off with fervor, he’s a goner, spilling hotly down his throat not moments later.

“Oh god…” Kim gasps, legs trembling underneath his cousin’s weight, his body sagging right back down into the mattress. His wrists ache from being bound so tightly. The pleasure floods his system, making him even more pliant. 

Kim pants into the air, waiting for the moment when Vegas finally pulls off of his spent cock to finally speak again. As Vegas rises up, triumphant grin in place, looking at Kim like a predator would his ensnared prey, Kim admits defeat. 

“Kiss me.” He moans. 

Kim can’t pretend any longer that this moment of weakness wouldn’t completely undo him. Years of careful composure flying out the window along with his willpower to stop the downward trajectory of any of this. It was toxic and they both knew it. That was probably why Vegas craved it so much. 

As his request was indulged in and their tongues dance with the aftertaste of pleasure and the heady increasing arousal in both of their veins, Kim reminds himself; It would never be love, it would always be the shell of something. All he could give were crumbs of attention when he knew damn well Vegas would always want more. He would become obsessive. 

Maybe it would just be sex, but it would consume them both. They absolutely couldn’t go down this road, together, and yet, here they were.

When strings are tied up
I never tried to cut loose from you and you
Now, I'm burning all my veins and it's back again
Can't hold back no more, push me through
Now, I'll never keep it hypothetical

Notes:

No promises that this wont end up somehow becoming a chaptered little monster on me... oh well~
