Work Text:
“5:30, I’m approaching my sixth hour,” Cooper spoke into his recorder, reclining in his seat. “I’m about to drink 6 more ounces of water. I’m a bit strained, though, it’s nothing too bad.” He crossed his legs and immediately decided against it when he felt pressure on his bladder. Uncrossing them had the chair making an odd little noise that he hoped wasn’t picked up on the recording.
“Previous attempts at this had me capping out at 10 hours,” He said. He cleared his throat. He reached for the bottle of water on his desk. He took a small sip, his throat suddenly going dry. “But I’ve noticed my tolerance getting better, my last undertaking lasted until the 11 hour mark. I feel like the increased amount of fluid intake may have me ending this much sooner, though.” He thought to himself for a moment, any other thought to take note of. Then, he decided to turn off the recording, having nothing else of importance.
Cooper rested his elbows on his desk, looking down at the paper in front of him. He was stuck in a loop, reading the same sentence over and over again. What looked to be a small glass of water had him feeling uneasy. He decided to just rip that Band-Aid off, and downed the whole glass. He almost immediately regretted it. He sat, his breath going shaky at the feeling of water sloshing inside himself. It settled into a different kind of discomfort after a second. He crossed his legs again, tried to get back to his work. Tried to convince himself he was working.
Another few minutes of mindlessly gazing at words, and he heard a knock at his door.
“Coop?” Harry asked, poking his head in the tiny open gap.
“You can come in,” Cooper said. Harry did just that, stepping inside, and clicking the door shut behind him. “Did you need something?” He asked, head tilting back to keep his eye on Harry as he walked over to his desk. Harry planted his palms on the edge of Cooper’s desk and leaned down to kiss him. Certainly a surprise, definitely not unwelcome. Cooper blinked up at the man.
“Did you need something?” He found himself repeating.
“No, just wanted to say hi,” Harry said, flashing a smile down at him.
“Hello,”
“Hi,” Harry laughed and kissed him again. “What are you working on?” He asked. Cooper had to look down at the paper, unsure of what he was supposed to be working on.
“Reading that updated autopsy report.” He said. Harry nodded and hummed a little “mm-hmm” at him. He stepped back, taking a seat in the chair opposite to Cooper’s side of the desk. Cooper started to feel a sense of unease sinking in. He crossed his legs tightly.
“Something wrong?” Harry asked. Cooper’s discomfort must’ve shown on his face.
“I am perfectly fine,” Technically not a lie, he was okay– but something about Harry sitting across from him while his belly felt tight had him feeling nervous. He squirmed in his seat, his face already feeling flush with Harry’s eyes on him. He sucked in a little breath.
Harry squinted at him. “Are you hard?” He asked, there was a tilt in his voice at the end, but Harry’s face broke into a wide smile.
“No.” Cooper snapped, too soon in their conversation’s rhythm to not be suspicious.
“Well, you look like it.” Harry teased.
“How can I look like it?” Cooper asked. He felt the need to prove himself, standing. “Look- I’m not-” The way Harry looked at him had his stomach turning. A wide grin, hand on his chin, visibly not convinced. He quickly sat himself back down.
“Right,” Harry said, slow, rolling through his mouth and heavy with his drawl. Something about that did have Cooper stirring in his pants. “Well- call me convinced.”
“I’m conducting an experiment,” Cooper started, already regretting his decision to explain this out loud to Harry. He barely even knew what possessed him to start speaking.
“An experiment,” Harry repeated back at him.
“Don’t make fun of me.”
“I’m not, keep going.” He said.
“I’m testing the limits of my body, how long I can go without urinating while also consuming a normal to high amount of fluids.”
“Didn’t realize you were into that sorta thing,” Harry said. “But I’m not shaming you or nothin’ “
“It’s not- It’s not sexual in nature, no,” Cooper replied. The nature of the conversation already had him half-hard. Too damn soon to not seem absolutely ridiculous to Harry— not that he seemed to mind right now. The man seemed to be in his own little mood. He rubbed the heel of his palm between his legs, then fixed his shirt, hoping to disguise the action. He looked up, Harry’s eyes were on the edge of his desk, where Cooper’s lower body was hidden. Damnit.
“So you would be opposed to this if it were sexual?” Harry asked. Cooper thought about it for a moment.
“I don’t think so.” Cooper said. “Are you into that sort of thing?” Repeating Harry’s words earlier. Harry’s hand came up to scratch under his jaw. He was silent for a few seconds.
“Depends. I don’t think I’ve ever really thought about it.” Harry said. “If all that stuff gets you looking like this— I’d say I’m into it, alright.” Cooper’s cheeks went hot. He swallowed, watching as Harry moved to stand. There was the click of his boots as he took slow deliberate steps towards his side of the desk. He sat himself on the corner, used the toe of his shoe to push on Cooper’s shin and turn his chair.
“How long have you been doing this little experiment of yours?” He asked. Cooper’s eyes stared across the room, trained on the clock hanging on the wall.
“Six hours now.”
“Must be a lot for you,” Harry’s voice went all breathy in the way that had Cooper shutting his eyes for a second.
“Is my involvement okay?” Harry asked, leaning over and reaching to trace Cooper’s belly through his shirt. Cooper opened his mouth to speak, then his teeth clicked together as his jaw went tight. He took a deep breath, made a second attempt.
“At this point, I find it to be absolutely necessary.” He heard Harry laugh a little in his throat. Gentle tracing turned into a solid, firm rubbing over his stomach. Cooper’s hands darted to his wrist, both of his hands wrapped around him with a white-knuckled grip.
“Shh,” Harry soothed him. “If you can go that long, I’m sure this won’t be too much for you.” He said, fingers splaying over Cooper’s stomach. He pressed harder, and Cooper had to slide one of his hands between his legs.
“Goodness,” Harry laughed.
“It-” He swallowed around a lump in his throat, “It helps, I find.” Cooper said.
“You find?” There was a tilt in his voice, one that came as he spoke through a wide smile.
“A bit of pressure, it’s distracting.”
“Suppose I could be helping with that distraction.” Cooper felt the breath from Harry’s nose hit his neck before lips met skin. It still came as a surprise to him.
“You’re what I need distracting from-” Chaste kissing turned to Harry’s lips latching under his jaw.
“Oh- semantics.” Harry whispered against the side of his throat. Then, his presence was gone, fast enough for Cooper to open his eyes. He was met with Harry kneeling, shuffling on aching knees closer to Cooper’s front. Harry took his hat from his head, placed it on Cooper’s stack of documents.
“This is a dangerous idea.” Cooper said, a wary edge to his voice. Harry looked up at him, smiling a little.
“I locked the door when I first came in.” Cooper couldn’t help but smile back at the tiny gesture of this being premeditated.
“I mean-”
“I know,” Harry interrupted. “Just don’t piss in my mouth.” Cooper swallowed.
“I feel like,” Harry began to undo his belt, “I feel like that may be easier said than done,”
“Why don’t we find out?” Cooper nodded at that, his eyes falling shut. Harry’s hand slid into his open fly, then through the flap of his boxers. Cooper sucked a breath in through clenched teeth. Open air hit him, just for a second, before scalding hot lips wrapped around him.
“Shit-” His hands scrambled, gripping the armrests of his chair. One hand clawed at the leather before plunging into curly hair. Harry hummed around him, only making Coop’s sanity slip further away from him. His jaw was slack, he hadn’t even realized he was moaning until he felt Harry huff a laugh out his nose. He clenched his teeth shut. His head was spinning, something deeply frustrating about the feeling. Some desperate need for release, for the strain in his stomach to leave him, for Harry’s mouth to be tugging on that cord. It left him feeling like he was fighting for his life to not spill over, every passing second making it harder. He opened his eyes, just for a moment, and catching Harry’s gaze trained on him, it had Cooper feeling like Harry knew all of that.
Suddenly, Harry’s lips went tighter, his cheeks sucked tight around him and- god he did something indescribable with his tongue. Cooper’s body sank, his back bending as he started to slide down into his chair. A gurgling noise left his throat that he didn’t even know he was capable of making. In one absolutely deplorable move, one of the hands on his hips moved to press into his belly again. Completely agonizing— and so damn good. A gasping moan ripped out of him, one that was loud enough to startle Harry. His head pulled off his cock, and he turned to look at the door.
“We can’t be loud-”
“It’s hard when-” He gulped, still trying to catch his breath. He didn’t bother to finish his sentence, instead making a frustrated noise, rubbing one hand over his forehead.
“I know, honey.” Harry’s hands smoothed down his thighs. He thought to himself for a moment, looking at the door again. “We could take my car- head back to my place.”
“Harry- I feel like I’m going to die if we don’t wrap this up soon.” He realized how dramatic it was, only after it left his mouth. He felt Harry kissing the inside of his thigh.
“Then, we’ll wrap this up in the car.” Cooper was frantic enough to not bother thinking that idea over. He tucked himself away, zipped his fly back up. Harry rose to his feet, smoothing down the hair that stuck up wildly from Cooper grabbing it, then placed his hat back on his head. Both men were grateful to have worn long coats to work. Grateful that their interaction was so close to the end of their schedules. Cooper had his coat buttoned around his front, Harry took his folded over his arm, carrying it over himself. The two made their escape, Harry giving an excuse to Lucy at the front, Cooper didn’t pay attention to whatever it was that he said.
The sky was already dark when they left the building. Each took their seat in Harry’s car, Cooper in the passenger side. Harry stole a short kiss from him, pulling back and quickly starting the car. He peeled out, heading towards the backroad that led to his cabin.
Cooper sat, squirming in his seat. He rubbed one hand between his thighs, some desperate attempt to calm his nerves. It had been long enough that he was breaking into a cold sweat, just from having a full bladder. He caught Harry’s glancing at him, how his lips went tight when he stared back at the road. He reclined into his seat, crossing his legs with his hand still on his crotch. He was sure Harry enjoyed the little show, but it still had Cooper hot under the collar, shame broiling in his stomach.
Then, Harry pulled to the side. There was a riverbank, one with a small lot beside it to park. He vaguely remembered this as somewhere Harry took him once, maybe to fish. He didn’t think on it for too long as Harry rushed to turn off the engine. It was pitch black, save for the tiny glow in the sky from a just-barely set sun. He felt the heat of Harry’s breath hanging between them before a hand came to the back of his neck, yanking him into a kiss.
Cooper moaned into Harry’s lips, arched into him as hands came to undo his coat. He felt like he was being pulled around, it had him dizzy, the feeling of being manhandled as Harry shoved his coat off his shoulders. Then, Harry’s mouth was gone. Cooper watched as he reached to open the door behind him, and his mind caught up. He mirrored Harry, opening his door and standing. He tossed his coat on his seat, and moved to sit in the back.
There was a moment where both were shuffling into a better position, interrupted by brief kisses. They settled on an arrangement, Cooper sprawled across the backseat of the car, Harry settled between his spread legs. Hands came up to undo Cooper’s belt, his fly. He yanked Cooper’s shirt to be untucked and leaned down to kiss his stomach. Cooper hissed, the tiniest pressure on his bladder having him try to squeeze his legs together around Harry’s shoulders. He felt Harry exhaling a laugh through his nose. He looked up at Coop, nuzzling his face deeper. His nose buried in the hair that stuck out Cooper’s open fly. Cooper felt him huffing, god did that have his throat going tight.
“Harry-“ He felt lips kissing the case of his cock, the tiny amount of himself that was bared when Harry pulled his waistband with his thumb. Pressure suddenly became unbearable, he felt like every fiber of himself was vibrating with the need to take a piss “Harry I don’t- I don’t know how much longer I can do this.” He said.
“Think you could cum? Like without having to-” Harry trailed off a little, looking up with his head still level to Cooper’s crotch.
“I don’t know,” Cooper swallowed. “We could try,” It was enough of an answer for Harry to bury his face back into Cooper’s crotch. He felt his tongue laving along the base of himself, before Harry slid his boxers back up, pulling his cock through the flap. Almost immediately, he slid his mouth down as far as he could without gagging. Cooper felt himself revert to a state of complete paralysis- or well, the parts of himself that were moving, grabbing at Harry’s shoulders, his hair- were completely out of his control. All of that, with that damn pressure on his inside. He was so close to his tipping point, and Harry’s mouth sucking around him felt like he was having his soul pulled out of him. Then, Harry pulled away.
“Take your pants off.” Harry stated, didn’t ask. Cooper wouldn’t say no to that, and with Harry’s assistance he pulled his slacks down his legs. He watched as Harry sucked on his own fingers, and lifted his hips, spreading his thighs a little further. Harry then spat on him, forcing a little breathy sound from his body. He caught a glimpse of Harry grinning at that, before he felt fingers rubbing at his asshole.
“Please-“ Cooper begged, the word left his lips before he even thought to speak. Something on instinct. Harry smiled, sucked his lips around the tip of his cock, and pushed his middle finger inside. Harry went straight for the kill, curving until his finger bruised into his prostate. Cooper felt like he blacked out, suddenly coming to with both his hands gripping Harry’s hand. He didn’t even realize he was speaking until he heard Harry’s mouth pulling off his cock.
“I got you…” Cooper wasn’t sure what Harry was replying to, if anything.
“Harry-“ Cooper’s teeth felt welded together, his jaw clenched hard enough to hurt. He panted, hissed through clenched teeth. It was painful, damn near torture. Regardless, Cooper felt like he was going to die if Harry stopped. Harry certainly didn’t let up, digging his finger deep into him. On instinct, Cooper’s hands moved to cup himself. God he was shaking. He didn’t even know he was until he caught a glimpse of his legs spasming. He rubbed at himself, body arching into Harry’s hand, jerking himself away. It was good, so damn good. But he felt like was absolutely about to piss himself. Harry must’ve known. He had to know. His hand moved to press on his belly, making Cooper see white as he came.
Even through the haze of his orgasm, he felt mortified at the feeling of hot spray hitting his stomach. Distantly, he heard Harry soothing him. He wasn’t sure what he was saying exactly, only that there was a hand rubbing his hip, the other inside him, working him through as he came. He was mostly sure he didn’t piss himself, mostly. It was hard to tell with the stimuli, with his eyes rolled so far back he felt blind.
There was a second, just when his orgasm faded enough for him to move. He whipped himself around, kneeling, bent over in the back of Harry’s car. His hands stumbled trying to open the door, grateful to any god that existed that his side was facing away from the backroad. He left one leg kneeling on the seat, the other planting itself on the ground outside the car. God it was fucking orgasmic to let himself go. He accidentally hit his head on the doorframe when his head whipped back. He was only distantly aware he was moaning when he heard his voice behind the cracking sound of piss hitting asphalt.
It felt like several minutes to him. He was sure that wasn’t biologically possible, but time felt hazy to him. When Cooper shook himself dry, and collapsed back into his seat, his eye caught on Harry’s hand working himself, his jaw slack. It had been enough time for Harry to pull himself free from his pants, then, at the very least.
“Give me a second and I can-“
“No- no I-“ Harry interrupted him, moaning. “I’m good- I’m-“ his hand worked faster, and he leaned over, curling into Cooper and pressing his face in his neck. Then, his entire body tensed, jerking for a second as he came into the palm of his hand, groaning like he was dying.
Cooper’s hand came up to lazily stroke the back of Harry’s head. He turned, kissing his cheek, whispering to him as Harry’s breathing slowed. Looking down at his own bare thighs, shining with sweat, it occurred to him that this was a terrible idea to do in the back of a car that wasn’t his. Harry lazily kissed his jaw, and the train of thought left him.
“God damn, Coop.” Cooper laughed, and felt Harry smiling against the side of his neck before kissing.
“Suppose there was some success with that experiment.”
“You can say that again— I’ll leave the ideas for further experimentation for when we’re in bed” Harry joked, kissing his neck again with a tired hum.
Right. “Further experimentation.” That already had Cooper’s thoughts racing
