"Stop fucking squirming," Roy orders, gripping Jamie's hip to hold him in place while Roy's fingers slide into his arse.
"Sorry," Jamie says, huffing a laugh into his arms. "I've gotta take a piss. Couldn't tell 'til we'd started. I'll just be two ticks."
He starts to lift up, so Roy removes his fingers to pin him down with both hands. "I didn't say you could go."
Jamie turns his head to the side, his eyes wide and wild when they meet Roy's. "Huh?" Jamie utters, half distracted, but his breath catches when he sees that Roy's serious.
"Roll over," Roy commands, smacking Jamie's arse and getting a grunt for it.
"C'mon, Roy. I'll be right back," Jamie huffs, as if he's reasoning with him. He falls onto his back with little grace and presses his legs together. "We don't even have to stop; you can stand behind me and grind on me. Might mess up my aim, but it'd be hot."
"You're not going anywhere," Roy says forcefully, making himself abundantly clear. He reaches down to rub two fingers just under the head of Jamie's cock, but just as Jamie starts to react, he reaches further to press those fingers down hard against his bladder.
Jamie inhales sharply, curling in on himself. "Ah, fuck. Roy," he says, an edge of pleading in his voice.
"You can't really be that desperate," Roy reasons aloud, "or we wouldn't have got this far." He stretches his hand out to press flat against Jamie's abdomen, making Jamie whine and squirm.
"Please," Jamie gasps, scrabbling for his dick and squeezing it. "I am, I am that desperate. Please let me go. I'll make it up to you, it'll be so good, swear down."
Roy studies him for a long time, easing up the pressure of his hand, but Jamie continues to fidget in obvious discomfort. "I think you can wait," Roy finally decides, grabbing at Jamie's hips and urging him back onto his hands and knees.
Jamie's surprise is evident, but he follows Roy's orders. "I ain't kidding; I really do have to piss."
"Hold it," Roy tells him, then pushes his fingers back inside.
Jamie moans and squirms some more as he settles back into position, trying to get comfortable. Roy watches him carefully for signs of distress, his own dick twitching as he feels how tense Jamie is against him.
"Fuck," Jamie breathes when Roy's fingers brush his prostate. "This feels—fuckin' dangerous."
Roy licks his lips. Jamie sounds fucking wrecked, like they've been doing this for hours instead of just barely starting. "You can take it," he says, his voice coming out rougher than he expects. He curls his fingers again deliberately and feels Jamie trembling. "There's a good lad."
"This—this ain't like you telling me not to come, babe. It's eventually gonna happen whether I want it or not."
"But not yet," Roy says, going for soothing. After a moment, Jamie agrees. "You'll tell me if it gets that bad."
"Yeah," Jamie says shakily.
Roy skims a hand up his back, feeling the heat radiating off of him. "This is really doing it for you, innit?"
"Fuck off. It's easier to hold it if I'm turned on."
Roy smirks. He nudges another finger in alongside his other two, pulling a gasp from Jamie. "It's fucking sexy, seeing you all desperate. Knowing if I pushed you, you'd piss all over our bed."
"You won't actually make me do that, though, right?" Jamie asks.
Roy grins and doesn't give him an answer. He takes his time fingering Jamie, slowing whenever Jamie visibly tenses, letting his free hand slide over Jamie's quivering thighs as he struggles to hold in his piss. It's always fucking heady how Jamie will give over control of his body to Roy, but this is some next level shit. "Think you can take my cock like this?" he asks eventually, shifting up to press his leaking cockhead between Jamie's cheeks.
"Fuck me." Jamie shifts his weight on his knees. "Yeah, I—I think. Go slow?"
Not like Roy has any choice, with Jamie tensing every five seconds, but it's worth it to feel the grip of him. The heat, fuck.
Once he's halfway inside, though, the mood shifts sharply. Jamie goes from needy moans to urgent whines, and Roy stills.
"Sorry, I can't—I don't think I can—I really don't wanna piss our bed, Roy, please," Jamie rambles, frantic.
Roy doesn't let his alarm show in his voice. "Shh, you're alright. I'm gonna pull out now."
"Slow," Jamie pleads.
"Slow," Roy agrees. He feels Jamie's body relax once the cramp passes, but still honors his word and eases out. He tries not to feel disappointed that nothing came of this, but at least Jamie's not calling him a freak and shoving him over to get to the toilet.
"Fuck, 'm sorry," Jamie says, rolling onto his back and biting his lip as he squeezes his dick. "It just got really bad there for a second, and I panicked." He blinks up at Roy, eyes pleading. "I don't wanna stop, though."
Roy feels as if he's had the breath knocked out of him. Not even this had been enough to freak Jamie out. He wants to keep going. Roy clears his throat as he stretches out next to Jamie. "How bad is it?" he asks, skimming his fingers over Jamie's hip, toward his abdomen. Jamie immediately goes red as his breath catches.
"Not sure," Jamie admits. "When it hits, it takes all my concentration not to piss all over meself. But with you inside me, it feels so fucking good at the same time. And then when it passes, that's fucking mint, too."
Roy lets his fingers drift over the bulge of Jamie's bladder just to see him squirm. He doesn't press down, but Jamie's blush spreads so prettily while Roy teases him. "D'you think you could stop yourself, if you started to lose control?"
"I could try," Jamie says. "What're you thinking?"
"I want you to ride me," Roy decides in the moment. "I don't mind getting piss on my chest."
Jamie shudders. "Fuck, that's fucking hot." He takes a second, squeezing his legs together, thinking it through. Roy lets him take his time, stroking his own dick as he waits. He didn't expect this to be such a thing when he'd given the quick command to wait. But fuck if it wasn't turning out to be one of the hottest things they've tried together. Jamie eventually nods to himself. "Alright, think I'm good."
Roy hadn't considered the view when he suggested this particular switch-up, but he finds himself completely captivated as Jamie lowers himself onto Roy's dick, gasping at the pressure it adds while his blush spreads down his chest.
"Steady," Roy says as Jamie grabs for his dick, biting his lip raw as he holds himself back again. Roy reaches up to rub at his nipples, hopeful that a distraction will help. "You're doing great. So fucking sexy, taking my dick like this. Bet you feel so full right now."
"Fuck, yeah—full. That's it," Jamie says reverently. He sinks down another inch, rolling his hips a bit. Roy has to fight not to fuck up into him, feel his heat gripping him tight.
Jamie lifts himself up again, then sinks back down with a roll of his hips, a long stretch of what they'd usually do as if it's being played in slow motion. "Yeah, that's it," Roy says encouragingly. He doesn't even mind the slow drag, not with the picture of absolute ecstasy on Jamie's face.
Jamie repeats the motion, gaining confidence until he gives two sharp gasps in a row, the sound going straight to Roy's dick. A spurt of piss hits him directly in the chest as Jamie clutches at his dick, trying to stop himself. He gets himself under control without going completely still, and Roy's chest expands with pride. "Fuck, Jamie. You're so fucking good. Making your body obey me."
Jamie lets loose a loud moan and grows bolder, bouncing on Roy's dick with as much abandon as he normally would. Roy curses and grabs at his hips, no longer able to stop himself from thrusting up to meet him.
He's not surprised when another warm gush of liquid hits him in the chest, but he is surprised—and impressed—by how quickly it stops while Jamie keeps up his rhythm.
Roy's aware that they can't keep this up for long, but Jamie's thighs and arse clench around him so nicely when he holds himself back. But after one wave that has Jamie's eyes going wide as he struggles to stop leaking, Roy urges him to slow down.
"Think we should probably relocate," he suggests, tilting his head towards the ensuite.
"Yeah?" Jamie asks, wiping his sweaty hair back from his flushed face. "You'll keep fucking me?"
"Like I'd deprive you after all this," Roy says, sitting up to squeeze Jamie's arse as he lifts himself up. "'Sides, I wanna know what it feels like when I finally tell you to let go."
"Fuck. Why is this so hot?" Jamie asks as they step into the shower together. Roy pulls him into his arms, knowing they'll need time for a proper cuddle once this is over.
"Because you like being desperate for me—almost as much as I like making it happen."
"It's fucking embarrassing, though," Jamie mumbles, pushing his face into Roy's neck.
"Fucking right it is," Roy says, pulling Jamie against him with hands cupped around his arse. "Couldn't hold your piss long enough for us to fuck."
Jamie gasps as Roy grinds into him, the pressure making him lose control immediately. But he curses into Roy's neck and stops himself again, clutching onto Roy the whole time.
"Good boy," Roy praises, squeezing his arse again before stepping back. "Turn 'round for me."
Jamie inhales sharply as Roy pushes into him in one smooth thrust, a stream of piss shooting from his cock immediately.
"Ah, fuck, Roy," Jamie cries, leaning against the shower wall for support as Roy pounds into him. "Please, can I—? I don't think I can hold it much longer."
"Not yet," Roy says, thrilled at Jamie's needy whine. He knows Jamie's body, and even if this particular activity is new, he knows when Jamie's having a good time. And right now, Jamie's delightfully overwhelmed, pushing back to meet Roy's thrusts, so Roy lets himself take his pleasure, feeling himself getting closer to the edge.
Similarly, he feels when the tension in Jamie's body gets to be too much. He slows down, reaching around to hold the base of Jamie's cock as Jamie grits out, "Fuck. It hurts."
"Let go for me," Roy murmurs in Jamie's ear, rolling his hips so Jamie can feel him.
Jamie lets out a huge breath as his hips stutter, but it actually takes a second for his body to respond. "Oh fuck," he says as piss gushes from his cock, leaning into the shower wall again to push back against Roy even harder. "Keep moving, please."
Roy swallows as he complies, feeling himself get overwhelmed as Jamie gives in to his desperation. There's just so much—the sounds of it all, Jamie's piss hitting the tile in spurts, the wet slide of Jamie's hand stripping his cock, the drain engaging as Jamie wets the floor enough to reach it. Not to mention the sweet grip of his body over Roy's cock, the way Jamie sags against him in relief even though he's far from empty.
"Fuck, I'm gonna—" Roy says, barely managing the few words before his cock is pulsing in Jamie's arse, filling him with his come.
"Oh god, I don't think I've ever been more turned on in me life," Jamie gasps, his stream steadily slowing to a trickle.
Roy reaches around him, pressing hard over his bladder as he takes over stroking Jamie's cock in his other hand. That gets him another one of those sweet gasps, like Jamie's gulping in air, as one final strong stream pulses out of his cock. Jamie babbles and begs as Roy jerks him off, his body twitching as he comes, barely seconds after he's done pissing.
Jamie sags against him further once he's spent, moaning as Roy's cock slips out of him along with some of his come.
"You're a proper mess for me," Roy mumbles against the shell of his ear, and Jamie huffs a laugh.
"Wouldn't have it any other way," Jamie replies, turning his head to the side for a lazy kiss. Roy indulges him, holding him up, knowing they'll need to get the shower running soon. But for now, he's content to live in this moment, supporting the body of the man that he belongs to, that's his in return, and be grateful for it.
