Jimin could sleep through an earthquake. He's been told this by almost everyone who's ever had the displeasure of waking him up in the morning. It's not that Jimin doesn't want to wake up, he just sleeps so hard that it's difficult to shake. He really can't be blamed for this particular fault of his. 

And yet, something – something – is finally working so well that Jimin feels excited as he slowly comes to, a tight delightful feeling in his chest, as if his body knows something his mind hasn't quite caught onto yet. 

"Good morning, sunshine." 

The voice is deep and low, a pleasant rumble that Jimin would know anywhere, anytime. He smiles and cracks his eyes open, finding Taehyung hovering over and gazing down at him. 

"Mmm'mornin." 

Jimin turns over in bed and scoots closer to Taehyung. He smells faintly like shampoo from the shower they had shared before bed. Unlike earlier in the day, it was as family friendly as a shower between cousins can get, much to Jimin's disdain. And they went to bed as they always do. 

But now there's something in the air, something in Taehyung's eyes too, that says things are shifting again. Taehyung still looks sleepy, like he hasn't been awake very long himself, but there's a very blatant life to his eyes as his gaze scans down Jimin's half-covered body and then back up, landing on his lips. 

"What's on your mind, Tae?" 

They haven't talked about yesterday since it happened. They had joined their friends, received a few judging glances (and okay, so maybe they earned those), but thankfully it seems that a few hadn't quite caught on and so their little secret stayed hush hush… unfortunately, it also stayed hush hush between them as well. 

"I didn't sleep all that great," Taehyung says quietly. "Kept waking up. Had to pee." 

Jimin's heart sinks just a little. It's not that he really thought Taehyung was just going to piss down his throat first thing in the morning, knew that Taehyung was probably just talking in the heat of the moment, but it's still a bit of a bummer to hear that Taehyung definitely went to the bathroom multiple times during the night and Jimin wasn't that bathroom. 

Jimin's skin breaks out in goosebumps just thinking about it. 

"Oh? Sorry, Tae. I told you not to drink so much before bed, but you never listen to me," Jimin says with a small giggle. Taehyung offers a lazy, unfocused hint of a smile. He's still entirely zeroed in on Jimin's lips. 

"Yeah, about that…" Taehyung mutters, and then he shifts slightly, almost like a squirm. "I never…  got up." 

Jimin blinks at Taehyung, his tired brain still processing that his cousin has even spoken, nevermind what the words mean. And before he can get there, Taehyung is rolling Jimin onto his back, and Jimin yips in surprise. Taehyung is quick to clamber on top of him, until his knees are on either side of Jimin and he's looking down at him with his hair still messed from sleep. 

Oh. 

Well. 

This is perfectly okay with Jimin. He rests his head back into his pillow with a shaky laugh, the weight of Taehyung on top of him is suggestive enough to kickstart his brain into high gear. 

"Well hey there cowboy, what're you doing up there?" 

"Nothin," Taehyung whispers, but his eyes are dark and there's a hint of a smirk on his lips that makes Jimin smirk back. 

"Liar," he accuses, wiggling around and watching as Taehyung sways. 

"Stay still," Taehyung laughs. "Just wait for it." 

"Wait for what?" 

Jimin stills, curious as to what Taehyung is planning, and then… and then there it is. Taehyung sighs softly and what follows is a warmth that spreads where they connect.  It seeps through Jimin's pyjama pants and touches his skin, and Jimin sighs just as softly, just as relieved at the man peeing in his lap. 

"Tae…" Jimin moans quietly. "That feels nice." 

It feels even better when the wetness reaches the sheets and begins to spread there too. He feels the wave of warmth ripple under his body, slowly inching inwards until he's laying in it completely. He's soaked. 

And yet Taehyung keeps going, an ode to his words the previous day, it just keeps going and going and… 

Taehyung pushes the front of his wet pants down just enough to pull his cock free and the stream hits Jimin's naked chest immediately. It goes up and up, leaving a trail of burning hot in its wake. Jimin closes his eyes as the stream splashes off his skin and around him. 

"Open your mouth," Taehyung husks and Jimin does so fast, he feels a blush rise to his cheeks. 

Piss slut. Taehyung's piss slut. That's what he is, and he knows it. He knows it, and now Taehyung knows it, too. 

Warm piss fills his mouth and, because he's laying on his back, it's hard to swallow and he coughs, choking on it. He turns his head to the side to breathe. Every inch of Jimin is soaking wet, but he feels on fire in the best way possible. 

Taehyung is still going, a truly remarkable thing. 

"You're wasting it," Taehyung snips, and Jimin feels a jolt of arousal spike through him. He's not sure where this Taehyung came from, maybe it's the early morning lack of inhibition, but Jimin hopes he comes out to play more often. 

Taehyung is right, he is wasting it. And a good little toilet never wastes its gift. 

Jimin grabs the back of Taehyung's thighs and guides him forward, and Taehyung scoots up his body until Jimin can properly lift his head and drink every last drop Taehyung has left to offer. 

It's utterly euphoric, the way it fills his mouth, sits on his tongue, glides down his throat. It has a distinct taste that Jimin will never find anywhere else, and he hopes to god that Taehyung never makes him look. 

God, he wishes he could jerk off right now, but Taehyung's body sits between him and his cock, so he settles for just grinding upwards in short, weak little movements that jostle Taehyung only slightly. 

He swallows down Taehyung's piss like the perfect vessel he is and a whine leaves his throat when it's gone and Taehyung is done. Jimin suckles on the tip of Taehyung's cock with wide, hopeful eyes cast upwards as Taehyung pats his cheek affectionately. 

"You look good with my cock in your mouth," Taehyung comments, moaning softly as Jimin swirls his tongue around Taehyung's cock. 

Jimin pops off with an audible sound, and heaves a great lungful of air. His tongue darts out to lick his lips, the taste of Taehyung's piss hitting him again. 

"Fuck me," Jimin whispers. "Please, it'll be so good, please Tae." 

Jimin can see the hesitation in Taehyung's eyes, and it's kind of funny to him. Here Jimin is, willingly drenched from head to toe in Taehyung's early morning urination and it's penetration that Taehyung is trepid about. 

"Jimin…" Taehyung starts. 

"Nobody has to know, Tae. Please ." Jimin runs his hands up Taehyung's thighs with a shaky exhale, his eyes zeroing in on Taehyung's cock in his hand. Despite being hesitant, Taehyung still strikes it in thought and he's growing harder in his palm. "You can have me however you want." 

Taehyung's eyes meet Jimin's gaze. "Anyway I want?" 

"Yes," Jimin breathes. 

Taehyung swings his leg over Jimin, who watches his cousin stand at the side of the bed and gives Jimin one last glance before he pushes his pants down his body. 

And this time, his glance shows no hesitation at all. It's dark and hungry and Jimin pushes his own pants off just in time for Taehyung to crawl back onto the bed, his heart racing with excitement.

"Turn over. On your knees," he says, tracing his fingers along Jimin's bare shin. The sheets squelch under their weight as Jimin does exactly as he's told, and Taehyung maneuvers behind him. 

"Jimin?" Taehyung says quietly. 

"Yeah?" Jimin responds, sliding his arms along the wet sheets and below his pillow, where he rests his head atop. Taehyung trails a hand over the swell of Jimin's ass, and Jimin swears he hears him swallow. 

"Are you sure? There's no coming back from this." 

Jimin chuckles softly, and retracts his hands, reaching behind him to pull his asscheeks apart. He feels the cool air on his asshole, still damp with Taehyung's piss. Taehyung groans behind him, and Jimin feels a whole lot of pride. 

"I'm sure, Tae. Wanna feel you. But if you're not– ah ." 

Taehyung's cock pushes past his rim slowly, and it burns. The waves of pain wash over him, but he moans nonetheless. That's Taehyung's dick stretching him, thrusting into him, bottoming out inside of him, and that thought alone is enough to overpower the lack of prep. 

Jimin is finally getting Taehyung is almost every way possible. 

Jimin's hands clench in the damp sheets beside him, teeth gritting and jaw clenched as Taehyung stills and Jimin's body works overtime to accommodate the intrusion. 

"Fuck, Tae," Jimin groans, "no warning, huh?" 

Taehyung drapes himself over Jimin's back, and hell, if that isn't doing something for Jimin, then nothing will. He's so full of Taehyung, in and around him, and it's setting his entire body alight like wildfire. 

With a soft kiss to the back of Jimin's neck, one that makes Jimin feel hazy and fuzzy and fond, Taehyung moves inside of him just a little bit, just a small thrust to test the waters. 

"I wanted it, too," Taehyung says, and yes. Yes. Yes yes yes. That's what Jimin wants to hear. He whimpers softly, grinding his hips back against Taehyung, encouraging his cousin to fuck him properly. 

And Taehyung does. He grabs Jimin by the hips and he thrusts into him with a desperation that has Jimin's stomach swooping violently. It feels so good to be so full of Taehyung, but knowing that Taehyung wants it just as bad makes it that much better. 

He feels dirty, in so many ways. His skin is still damp, especially where it touches the bed. He's covered in piss, moaning his cousin's name, mind already zeroed in on whether or not Taehyung will come inside of him like he really wants. 

"Fuck, harder Tae ," Jimin pleads, fingers digging into nothing as Taehyung picks up speed and jostles him around, each hard thrust pushing him forward. 

When Taehyung comes, it's sudden and with a loud moan that surely has the potential to wake up the rest of their guests. He buries himself into Jimin, clutches at his hips like a vice, Jimin's name slipping off his tongue. 

Jimin reaches between his own legs and jerks off with a whine as Taehyung fills him with dirty, immoral cum. He's so hard and his cock is leaking, dripping down to the wet sheets below. 

Taehyung doesn't pull out, and Jimin thanks whatever god is listening for that. He's so close now, and all he wants to do is come on Taehyung's cock. Even if it's just once. He fists his cock with fervor, panting " don't move, don't move, not yet " into the air. 

And then he feels it. He feels a new warmth emptying inside of him, and for a split second he furrows his brows in curiosity and then it hits him. Taehyung is pissing again, inside of him, and it's so much more than Jimin could ever have asked for, and Taehyung is giving it to him. For free. 

Jimin's eyes roll into the back of his head as his jaw hangs open in a silent moan, and he comes so violently that his vision goes black and splotchy. Taehyung holds him on his cock as his piss fills Jimin up to the brim, until Jimin is squirming with the sheer pressure of it all. 

He feels like he's made of jelly as the tension rushes out of his body, begging to be dropped back down to earth. But Taehyung is still there, holding him steady and up. 

He pets down Jimin's back affectionately. "How's it feel?" he asks, and Jimin can't help but smile at the genuine curiosity in his tone. 

"It feels really fucking good, Taehyung. 'M so…" 

"Wet," Taehyung chuckles. 

"I was going to say full, but that too." 

Taehyung hums with another small laugh and then he inhales deeply. "You ready?" he asks, and Jimin doesn't need to ask for what. He clenches around Taehyung's cock and nods. If they don't do this soon, Taehyung will go soft and it will be another missed opportunity. 

Taehyung pulls back and slips out of Jimin, and even though Jimin does try to clench himself closed (for science), it's futile. Piss and cum rushes out of him and down his inner thighs, joining the already ruined sheets below. Jimin is moaning again, can't possibly imagine a better feeling. And Taehyung is making some sort of noise behind him, pushing two fingers inside of Jimin just to watch it gush around them. 

"Fuck Jimin, that's the hottest thing I've ever seen," Taehyung groans, and if he leans forward to dip his tongue in Jimin's gaping, wet hole, well, that's just for them to know about. 

Jimin squirms with a breathless giggle. "Taehyung… stoooop." 

Taehyung pats Jimin's ass gently and then he's rolling Jimin over onto his back. Jimin smiles fondly up at Taehyung. "I'm disgusting." 

"That you are," Taehyung mutters with a cheeky smile and Jimin reaches up to swat at his cousin with a laugh. 

"Not like that! I mean I need a shower. We need a shower. Everyone's gonna wake up soon." 

Taehyung glances around the bed with a cringe, and Jimin's eyes follow the trail. "I think we need to burn this bed," Taehyung whispers, a sheepish smile blooming on his face. 

Jimin's hands drag along the wet sheets, and he has to remind himself that he's not allowed to get aroused again. Which, in his defense, is hard for him when he's laying in a bed drenched with his cousin's piss. It's starting to cool. 

But he does concede to getting up, and he and Taehyung clean up as best they can. Taehyung is right, the bed is as good as trash; they really need to be proactive next time.

The two cousins shower together in the early morning hour and manage to make it to the kitchen, clean and inconspicuous. And when their friends join them, fresh from sleep, it would appear that no one suspects a thing. 

No one except for Jungkook, who narrows his eyes across the breakfast table. 

"Why does Jimin look like he won the lottery?"
