Chapter Text
It started out innocent enough, Gavin was a stubborn shit that didn't want to go pee, and Michael was just an innocent bystander. Sooner rather than later though, Michael started to take notice. REALLY take notice. Gavin would go out with the group for bevs, drink too many, and end up next to Michael wriggling and gnawing on his bottom lip because he didn't want to be bothered with going to the bathroom. Michael developed an obsession with the flush that would blossom up on his cheeks, the little whimper he would let out when he finally had to give in and get up to pee. At first he had wondered why he enjoyed this, but then in the very Michael-like manner, he said 'fuck it'.
He did feel kind of bad once he started exploiting Gavin's little quirk for his own pleasure. It was him, Gavin, Ray, and Kerry at Michael's house one evening for pizza and video games. Gavin was drinking and Michael started giving him water between drinks under the pretense of 'not wanting to deal with his hungover ass the next morning'. As the night went on they decided to put in some new to Netflix movie and just chill. Ray and Kerry sat on the floor and Michael was snuggled with Gavin on the couch. It was their thing. Platonic cuddles. Right? Maybe. Neither of them had the time to look anymore into it than that. Michael was just waiting for it, and sure enough, as soon as the first scene ends, Gavin starts to squirm. Shift, shift, wiggle, grind. This is his pattern for the first fifteen minutes. Michael pretends not to notice, just draws Gavin in closer, resisting the urge to press against the lower part of Gavin's stomach where he's so full. Michael shudders at the thought and tries to calm his brain down. If he pops some wood he'll lose the squirmy shit sitting next to him.
Gavin hits the point of having to pee where the urge calms down a bit. Michael's a bit disappointed, but he knows it will come back even stronger in a few minutes, so he tries to focus on the movie he's been ignoring for the past however long. The first little pant sends a shock wave down his spine. He glances over at Gavin, who isn't even looking at the screen anymore. His eyes are squeezed shut and he's biting his bottom lip. Letting out tiny squeaks every now and then. His rhythm is long gone. All that's left are long grinds to try and ease the ache. Michael doesn't let go of him, doesn't tell him to go, just watches as Gavin's hand twitches by his side. He's about to resort to the squeeze maneuver, a sign that he's long gone. Michael is just gazing at the sweat starting to bead up on Gavin's temple when Ray swears and pauses the movie.
"Jesus Christ, Gavin, just go to the fucking bathroom," Ray turns to glare at Gavin, who thanks him and tears out of Michael's arms, doing a little skip-run to the bathroom. Michael looks after him and tries to imagine the face he'd make. How he'd throw his head back in pleasure as he hauls his dick out. Maybe he'd let out a quiet moan to echo along with the splashing. Maybe he let a little go in his pants before he made it. Michael has to bite his lip from letting out a tiny sound and crosses his legs to hide the little-more-than a semi he has going on. Gavin comes out of the hallway, zipping up his fly as he does so, a glazed look in his eyes.
"Thanks, X-Ray," he murmurs and collapses back into Michael's arms on the couch. Ray rolls his eyes.
"Just go pee when you need to dipshit. This is the only scheduled intermission though," he un-pauses the movie and Gavin goes back to cuddling up close to Michael, his eyelids droopy from the strain and release.
Michael is so fucked.
It's after work and Gavin catches a ride home with Michael, but not before chugging the rest of his redbull and the glass of water on Michael's desk. Michael notices this and grins to himself. It's a good twenty minute drive to Gavin's house. Thirty if he stops for gas, and forty if traffic is bad. He bets on Gavin needing to pee in ten. Michael's assumption is right, and ten minutes later, just as they pull out of the gas station, Gavin starts to fidget. Michael notices the need escalating pretty quickly. He passes two more gas stations and Gavin doesn't say anything. He merges onto the highway and glances over at the person making all of the quiet shuffling sounds in the car. The red is starting to rise on his cheeks, and something else is starting to rise in Michael's pants, but he ignores it. Five minutes later while they're still on the highway (Michael may have taken the long way around) the panting starts. Gavin is sucking in air, wiggling, panting, repeating. It's driving Michael fucking insane. And when did he turn from a straight, laid back dude to the creeper that jerks off at night to his friend being a stubborn little shit? He decides not to dwell on that and instead nearly jerks them off of the road when he sees Gavin start thrusting into the air. They pass an exit with a rest stop. Gavin grabs his crotch a squeezes, too lost in the pressure now to care about Michael hearing his little whimpers.
His eyes are shut and his mouth alternates between gaping open and sewn shut with his teeth. Michael almost takes the next exit out of pity, almost. He figures when Gavin wants him to stop he'll say so. But now the other man is bouncing and whimpering with a new gusto. It leaves Michael breathless. He's struck again with the overwhelming urge to push down on Gavin's bladder and see the man's eyes go wide at the extra pressure. Gavin finally swears and chokes out a few breathless words.
"Michael, please, oh my god, pull over I'm sorry I can't hold it anymore I-" he squeaks and Michael looks over to see a tiny wet patch on the denim of Gavin's jeans. He swerves over onto the side of the road violently and watches with a full mast erection as Gavin flings the door open and hauls his dick out, tiny beads of light yellow on the tip. His knuckles are white and he lets out the most satisfied moan Michael has ever heard as he leans to the side and lets go. The sound is perverse, wet against the rocky asphalt on the side of the road. Gavin is shuddering like he's just had a mind-blowing orgasm. Michael makes sure to save every detail of this in his memory. He's going to need it as soon as he gets home. Gavin finishes and slumps back against the seat. His lips are raw and his hair is damp against his forehead. His soft dick is resting against his jeans next to the small wet spot and he blindly reaches for the door to pull it shut. He gives Michael a sheepish smile and shuts his eyes, body lax. Michael gets back onto the road and finishes the drive. Glancing too much at Gavin's dick still sitting just outside his pants.
When Michael gets home, he immediately heads to his room and shucks his pants. He takes his aching cock in hand and furiously strokes it. He comes into his hand on the memory of Gavin's terrified face when he leaked. He feels filthy, but in all the right ways. He cleans himself up and wanders into the living room to play a game. He wonders if he and Gav will ever fuck. Would he understand Michael's kink? God he hoped the answer was yes.
"Hey, Micoo," Gavin's voice whispered in Michael ear and his arms wrapped around the mans waist. Gavin was obviously drunk, but so was Michael. They were in the happy space, not too drunk to be stupid and sick, but drunk enough to where everything felt warm and fuzzy.
"What's up, Gavvers?" Michael kissed the Brit's messy hair and chuckled when he felt the telltale sign of Gavin squirming against him.
"Just chugged my beer and Geoff made me drink a bunch of water," he leaned his head against Michael's chest and they tried halfheartedly to sway to the music playing over Burnie's surround sound. Gavin's wiggles got progressively worse and Michael got progressively more turned on. Normally he would at least try to hide it a little, but fuck it. He was tired of being sneaky. Plus Gavin was right there all warm and pliant and filled to the brim. "I need to pee," Gavin murmured into Michael's chest, but made no move to break free of his hold.
"Go pee then," Michael made no move to let go of him.
"Gonna hold it for me?" Gavin nuzzled against him. Michael's brain tried to process that sentence, died, rebooted, and came back to life with a burning desire.
"Fuck yes," Michael let Gavin lead him by his wrist to the bathroom. Michael lifted Gavin onto the sink and came into his personal space, checking for a signal that this was okay. Gavin smiled and leaned in to capture Michael's lips with his own. Michael let out a surprised moan and leaned into Gavin, finally, FUCKING FINALLY, pressing his hand against the Brit's swollen abdomen. Gavin violently bucked his hips and bit down on Michael's lip. Gavin pulled back, his pupils blown. He was still shifting his hips against Michael.
"Gonna have to jerk me off, get rid of this," he led Michael's hand to his prominent hard on, "so I go. I need it Michael," Gavin buried his head in Michael's neck and started nibbling. Michael just moaned and stood Gavin up. He lead him to the toilet and popped the button on Gavin's jeans. He fit his own clothed erection into the curve of Gavin's ass. He kissed Gavin's neck as he pulled hard flesh from it's confines and started slowly stroking, using some of the precum to wet the way. Gavin threw his head back and groaned, grinding into Michael's hand. Michael used his other hand to press against the bulge in Gavin's abdomen, causing the other man to cry out and shudder against him. Gavin was beautiful like this. Filthy and desperate.
"You're so beautiful like this," Michael voiced his thoughts.
"I bet I'm even more beautiful bent over your bed. Might have to get new sheets though," Gavin hissed through the pleasure, "Fuck, thought I would have to piss on you for you to get the hint," he let out a long moan when Michael bit his neck harshly.
"You knew?" Michael growled.
"You're not exactly sneaky love. I could see your boner from space-" Gavin's sentence was cut off in a whine as his hips stuttered. Michael sped up the pace and Gavin shuddered. Michael felt the cock in his hand twitch and watched white blend in to yellow as it hit the toilet bowl. Michael rutted into Gavin's shuddering form until he heard the stream stop and saw Gavin turn around, still dripping a little. He sucked in a breath as Gavin sunk to his knees and pulled Michael's dick out of his jeans. He gave him a good few pumps before wrapping his lips around the head and slowly sucking back and forth. Michael bit the back of his arm to stifle his moans, one hand fisted in Gavin's hair.
"Maybe you could blow me next time, figure out how it tastes," Gavin came up for air. The image punched Michael in the gut and he hauled Gavin back onto his dick, fucking into his face as gently as he could without upsetting the other man's gag reflex. He came with a muffled shout and felt even more arousal try to burrow its way into his stomach when he saw the dribbles of cum on Gavin's chin. Filthy. That's how to describe the sight in front of him. Piss stained jeans, dick out, sex hair, glazed eyes, and cum running down his chin, Gavin Free looked like the poster boy for the word debouched. Michael grinned and helped Gavin off the floor, kissing away the remains of himself. He flushed the toilet and tucked Gavin's dick back in his jeans for him. They laced hands and opened the door to a line of three angry people, each of them a little chagrined. Michael gave an apologetic smile and Barbara just rolled her eyes.
"Fucking mavin."
