Chapter Text
Dennis is in an awful situation. A pretty fucking embarrassing one as well. He's stuck in traffic, Mac in the passenger seat next to him, jamming along to the godawful music he had picked because it's his day to pick the music, completely oblivious to Dennis's slightly less than obvious issue. He's doing his best to hide it, but his best is bad, so he's hardly hiding it at all. His leg is jittery and he's clenching and he can't sit still worth shit, so he eventually puts the car in park so at least he won't accidentally slam into the unmoving car in front of him. Or maybe he wants to do that. Except that doesn't seem like much of a solution.
Unfortunately, nothing seems like much of a solution. Except pissing himself like a child, using Mac's jacket to cover up, then cleaning his car once they get back to the apartment, whenever that'll be. But that's an awful idea-- barely even an option. Possibly his only option.
Fuck, he's fucking fucked. Mac still has yet to notice. He's not sure he wants Mac to notice. It's embarrassing as shit, sure, but Mac may be able to help, and it's not as if they haven't done plenty of gross shit before. In fact, he can guarantee both of them have cleaned their couch after Charlie has stayed over. Or maybe both of them have flipped over the cushions and called it a day, even though it most certainly was not a day, and he's sure the cushions have been flipped enough times that it makes no difference except for whichever side is the freshest.
The traffic doesn't budge. He can't stop moving his legs. Mac seems unbothered.
"Shit, dude, I gotta piss," Dennis says, deciding to tell Mac before he can get it in his head that he doesn't want Mac to know. Mac's not going to make fun of him, he knows that, even if it is embarrassing.
"Yeah?" Mac questions.
"Really badly. This traffic's not helping."
They haven't moved in at least thirty minutes. Not even an inch forward.
"Are you gonna piss yourself, dude?"
"Yeah, I might," Dennis replies, truly believing he might. Beer runs straight through him, doesn't it everybody? He's also had some wine, which is just as bad as beer, if not worse, and quite a bit of water, because he's trying to stay hydrated through all the beer and wine. He hadn't had to piss when they left the bar, but it's been getting worse and worse, making the traffic jam progressively more frustrating
"That's pretty gross," Mac says. "What do you think is with the hold up?"
"Probably an accident. People can't drive for shit. Do we have a bottle anywhere?" He knows there isn't, but he has to ask unless he wants it to lay heavy on his mind. Mac knows they don't as well but he looks around for Dennis's sake, to give him an illusion that this is a fixable situation outside of an accident.
"No. Nothing," Mac emphasizes, so Dennis won't ask him to look for a plastic grocery bag or something similar next.
Dennis groans and grips his crotch. "Fuck," he hisses.
Mac stares at him, unable to look away from his crotch, but also desperate to stare at his face. He's seen Dennis in many different situations in their thirty year tenure, but he's not sure he's ever seen him desperate to piss. At least not this desperate. He hadn't paid attention to him for ten minutes or so, and now he looks already ready to burst.
"Why don't you just go to a gas station?" Mac suggests. Dennis looks at him as if he's the dumbest person he's ever met giving him the dumbest suggestion he's ever heard.
"If I do that, then the traffic is going to move, and you're going to drive off without me."
"Traffic hasn't moved in thirty minutes. I think you can risk it."
"No, I don't want you driving off with my car."
"So you'd rather piss yourself?"
"Yes," Dennis says, resolute.
"That's ridiculous," Mac says. It sounds ridiculous to Dennis now that he's said it, but he has to stick to it now or otherwise Mac will never shut up about it.
Mac keeps going, keeps bugging him about it, because of course he'll refuse to shut his mouth. Dennis should've known telling him was a bad idea; should've known Mac would just push it to its breaking point. "So, you'd rather piss on the interior of your car?"
"Would you rather I piss on you?" Dennis snaps. Mac shrugs, nonchalant, but Dennis can read him, and he obviously isn't a huge fan of the idea. Although, there's no clear disgust. Interesting.
"You've done it before," Mac says, unwilling to express his distaste.
It distracts Dennis enough that he chuckles, mostly to himself, remembering how desperate for his approval he managed to get Mac to want that day. Not that he isn't always desperate for approval, but that day was extra bad.
Unfortunately, the chuckle does nothing to ease the stress on his bladder. He tenses again.
"You're going to piss yourself," Mac says. He won't look away from Dennis, but Dennis can't figure out if he likes it or not.
"Traffic will let up soon, I'll be fine once we're moving," Dennis reasons, but it's practically a lie, to himself and to Mac, because he knows he won't be better if they are moving. It'll probably get worse the closer he is to their apartment and the idea of relief, not to mention that once they start moving he won't be able to grab onto his dick like he is now.
"I doubt it," Mac says, because he's incapable of keeping anything to himself.
Desperation shoots through Dennis and he makes a pathetic noise, leaning down until his forehead is on the steering wheel. He manages to catch himself before anything comes out, but only barely.
"You're not gonna make it, dude," Mac says. Dennis grinds his teeth together, then in a moment of frustration, honks the car horn a few times in succession. This sets off a chain of people honking their car horns, all hoping to accomplish something, knowing they won't.
"I'm gonna make it," Dennis grinds out through his teeth. His legs are crossed again, his thighs pushing against eachother hard.
"A hundred bucks says you won't make it. This traffic's not gonna move."
Dennis hesitates. He's not gonna make it, he knows this, but he doesn't want to agree with Mac, so it comes down to whether or not he'd rather waste the hundred, or take a hit to his pride. He figures that they basically share their money, anyway, and he'll probably end up giving Mac that money for something stupid, so he might as well take the bet and save as much pride as he can. Besides, it gives him another reason to not piss himself, as if he needs another reason other than being a full grown adult.
He probably needs another reason. He was three seconds away before Mac made the bet. Now he's at least fifteen minutes.
"I'm gonna make it," Dennis repeats.
"So you're taking the bet?"
"I'm taking the bet."
"This is gonna be the easiest hundred I've ever made."
Dennis sneers at him, then slides his hand in between his thighs so he can grab his crotch again. He truly does feel like he's seconds away from bursting. It's beyond uncomfortable, beyond borderline painful, it is painful. Even if they weren't stuck in traffic, or he was willing to walk to a gas station, he wouldn't be able to make it. Standing up would be enough to make him let go. He's happy that the Range Rover's interior is leather, so it'll be relatively easy to clean, because he's going to have to clean it.
"I've never had to piss this badly before," Dennis claims. Mac smiles at him, obviously teasing, obviously finding this amusing.
"Just let it go, dude. You're gonna give yourself an infection."
"Shoulda told me that before a hundred dollars was on the line. I'll use the hundred to treat the infection."
"It costs more than a hundred dollars to treat an infection."
"Whatever, bro. I'm winning that bet."
He's not. But now it's fun to act like he has no clue how his own problem is going to play out, while Mac does. It's a form of tricking Mac, he justifies. As if Mac is smarter than him, and he's not.
Dennis gets distracted enough that he relaxes too much, some of the piss escaping. He manages to stop the flow after less than a second, before it can get out of hand. It doesn't show on his jeans, but he can feel it in his boxers, making it all that slightly bit more uncomfortable. He undoes his pants, pulling the fly down, just for that little bit of relief on his bladder. Mac watches him, letting it happen, which is good because Dennis doesn't know what would happen if Mac told him he couldn't. Still done it anyway, but would have had to fight for it.
He stretches his legs out, feeling them pop in various parts, then recrosses his legs and pulls himself straight up on the seat. Immediately after settling, he uncrosses his thighs, then crosses his ankles, tucking his hands between his thighs. He's just moving from position to position at this point, but whatever works is what he's going for. Unfortunately, nothing is working at this point. He's staring down at his legs, his eyes closed, completely focused.
"Dennis," Mac says. Dennis doesn't respond, too focused on not letting anything leak. If he could, he would stop listening to Mac all together.
Mac repeats himself. Dennis still doesn't listen.
"Bro, look up, traffic's moving," Mac says now, instead of just saying his name again.
Dennis looks up, his heart jumping with excitement. It falls back down quickly. Mac isn't lieing, traffic is moving, but only by a foot or so, the car in front of him steadily inching forward. At least it's something and the prospect of relief is enough to make him not as desperate, even when he has to uncross his ankles in order to drive.
It comes to another standstill at one of the corner lights. Mac points across Dennis at the gas station to his right.
"I will forfeit the bet if you go use the bathroom," he says.
Dennis balks. "No way. Not now that traffic is moving."
"Suit yourself, bro, but don't say I didn't give you an out."
"I'll keep that in mind while I'm pissing myself," Dennis shoots back.
They make it past the light, only after being parked in the middle of the intersection and getting plenty of pissed people unable to go around them. When they honk, Dennis honks back. Mac lets it happen without a word.
"Are you saying you're going to piss yourself?" Mac says, at least five minutes after Dennis admits to it.
"Yes, I'm going to piss myself!" Dennis whisper-yells, as if anyone can hear them. "Don't act surprised."
The traffic is clearing out and now they're managing to make it past five miles per hour. It'd be a miracle if it wasn't forcing Dennis to move his legs and give most of his attention to driving. They have yet to drive past the cause of the traffic, meaning at any second they could get stuck again.
"If you know you're gonna piss yourself, why don't you just do it already?"
It's not the worst question Mac has ever asked. As each second passes, it gets more and more tempting.
"Because if there's a slight chance I can use a toilet, I'm going to take it. We're only three minutes from the apartment."
"Yeah, and it's only a ten minute drive from the bar to the apartment. We've moved half a mile in an hour."
"Shit, Mac, you won't let me have that?" Dennis accuses as if Mac stole something from him. Mac grins.
"I want my hundred dollars."
"And I want relief," Dennis slips out. He winces when he hears himself say it.
"So go!"
"No!"
Mac sighs. "You're only hurting yourself. Look, we're not moving anymore."
"Don't remind me."
They haven't moved in at least five minutes. They had made considerable progress, at least.
"Have to admit, I'm thirsty as shit," Mac says. "I was thirsty before we left the bar, but I was just gonna wait."
Dennis hates that he's thirsty too. It makes sense, considering all the liquid is in his bladder, but it's definitely still a type of torture.
Dennis ignores him, doesn't want to let his thirst slip. If he does that, Mac may jog to the gas station and force him to drink a bottle of water, which will give him a bottle to piss in, but the cons outway the pros. No more liquid.
Traffic moves a couple of yards. They're so close to the apartment. Dennis has no idea how he'll get himself to the elevator and in their room, but it still feels nice to be this close.
"I don't know how you've lasted, dude," Mac says. Dennis is too focused on continuing to hold to brag about it as much as he would like to brag about it, but he still manages to say something about having complete control over his body. Mac makes a noise of dismissal. "I would've let go by now, that's for sure. I'm honestly impressed. 'Course, I wouldn't want to give myself a bladder infection, but you don't seem to care, huh? That's strong. You're strong."
Dennis doesn't pick up on what Mac is doing until Mac's hand ends up on his bicep and he jerks away, which causes him to leak. This time the flow is harder to stop, but he manages to do it. His boxers had dried, but they are definitely not dry anymore, and it's uncomfortable. Once Dennis gets under control, he glares at Mac.
"Were you trying to flatter me into wetting myself, dude?"
Mac groans. "Yes! I wanted to distract you."
"That's cheating!"
"When was that established to be cheating?"
"It was implied with the bet."
"Implied? That's not good enough. It's gotta be stated."
"Since when was that the rule?"
"Since I made the bet."
"Oh, fuck off," Dennis exclaims. "Look, we're only a turn away and we're moving."
"Are you really going to be able to get out of this car and walk?"
Dennis grimaces. This wouldn't be as big of a problem if he was still young. He used to be able to drink a lot of beer before having to piss. Getting older is a sham.
He makes the turn into their building's parking lot and parks the car, turns it off. Mac looks at him with a raised eyebrow, waiting for him to make the first move.
"I think once I start walking initially I'll be fine."
"Uh-huh-- sure."
"What does that mean?" Dennis snaps.
"It means I know and you know you won't make it."
Dennis sneers, then undoes his seatbelt and opens his door and swings his legs out and clamps down because he can already feel some leaking out and he can't afford for it to get any worse, and not only does he not want to lose a hundred dollars, he also doesn't want to have to walk through the lobby with soaked pants. This situation has ruined a lot of his self respect, but it's not gone completely. So far only Mac has seen his desperation and he'd like to keep it that way.
He shimmies out of the seat and onto the ground and after looking quickly that no one is in the parking lot, he grabs his dick through his pants and holds it.
Mac is at his side and gently pushes him out of the way so he's able to close the door. "Lock it, bro," he says. "You wanna get to the toilet, right?"
"Don't say that word," Dennis demands through clenched teeth. He manages to lock the car without letting go of his dick.
"What? Toilet?"
"Yes!"
"You are not going to make it, dude. I'd give up now if I were you. Look, I'll even give you my jacket." Mac goes to take it off, but Dennis's arm shoots out and holds his bicep, keeping the jacket in place.
"No," Dennis says, then takes his hand from his dick and starts walking towards the entrance of the building. He's walking quickly and Mac has to jog to catch up, then match his pace. They get to the door and Mac opens it for them and Dennis still doesn't slow down as they get into the elevator. He's dancing around and it gets much more noticable once the doors close, but he has to stop and hold himself again the moment it starts moving. Mac is watching intently as this happens, but, despite not wanting to admit it, he's impressed with Dennis's resolve.
The elevator opens and Dennis is rushing to the apartment before Mac has even realized the doors are open. Mac is willing to unlock the door, but Dennis is already fumbling with the keys and putting it in the lock, it taking forever to turn because he's dancing around like a little kid. No one is in the hallway with them, but it seems like Dennis isn't too concerned with saving face at this point.
Dennis barely waits for Mac to get into the apartment before he's slamming the door shut and suddenly he isn't moving, his legs collapsing underneath him, his hand clutching his crotch like his life depends on it.
"I can't make it to the bathroom," he grits out. "I can't. I just can't."
"Come on, dude, you got so far," Mac reasons, but Dennis snaps and glares at him.
"I know, Mac! But I'm barely stopping myself now! I can't walk. I'm just going to stay here forever."
"That's ridiculous. Just let go, then."
Dennis has his eyes screwed shut and his legs are trembling and he's leaking for real now and he can't stop. "Go get me a bowl," Dennis demands.
"Hell no, dude, that's gross. We'd have to throw it away. We'll just clean the floor."
Dennis can't fight him, but he sure as hell wants to. "Fine," he says, and that's literally all it takes for him to stop trying to hold it in. It comes out slow at first, from the long time he tried to hold it in, but once his body gets the idea that it's okay to release, it speeds up. Dennis has never looked more in bliss. The furrow of his brow smoothes out and his mouth hangs open with a pleasant noise, his hands relax and his body goes limp. He's putting all his weight against the door.
Mac has to admit, it's pretty hot to see Dennis like this. Dennis is helpless and vulnerable and, despite all his talk of being the golden god, susceptible to basic human issues. If seeing him piss himself on the apartment floor isn't proof enough that Dennis is as human as the rest of them, then nothing is.
Dennis is still going. It's making a very audible hissing sound and a puddle is starting to spread. There's no clear sign that Dennis is even close to done. How much urine can one man hold? A lot, apparently.
Mac watches the puddle for a few seconds, then moves his eye sight to Dennis's crotch, where he can clearly see the liquid flooding out of his jeans. Mac bends down to Dennis's level and Dennis blinks at him wearily, relief still written all over his face. It's that look that kickstarts Mac into kissing Dennis, having to get into the puddle in order to reach Dennis's lips, but he doesn't care. Dennis makes a cut off noise when their lips connect, but he melts into the kiss easily. When Mac undoes Dennis's jeans and takes his dick out, the stream doesn't end and Dennis doesn't react past a moan falling out of his lips. He pulls Mac closer to him, Mac practically falling into the puddle and his pants are now soaked, but it's nothing compared to how Dennis is still pissing and Mac is directing it upwards onto both of their chests and even though he hated when Dennis pissed on him at the zoo, this feels different. It feels better, like he's in control of Dennis's mess.
The stream stops abruptly and Mac takes it as his chance to start stroking Dennis's dick. It twitches with arousal and a burst of piss shoots out, making Dennis's hips jerk. He's clutching onto Mac's back and digging his nails into his shirt like his life depends on it and their kisses are so messy and uncoordinated and he can't help but release small streams of piss before he has nothing left and the entirety of this situation is ridiculously hot.
Mac is trying to find friction in his jeans but failing miserably at it. Everything is so wet and it's genuinely getting hard to move, not to mention that how tight his jeans are is now becoming a painful problem. He decides in a split second that taking his jeans off is the best course of action, but it's hard when Dennis refuses to let go of his mouth. He's chasing after Mac, begging him to stay, to fuck him, to do anything.
Mac stands up and holds his hand out for Dennis and Dennis takes it without a care to the piss on it.
"Bedroom?" Dennis asks.
"Bedroom," Mac confirms.
On the way to the bedroom, Dennis manages to lose his shoes and struggle with his very wet jeans, but he ends up stopping halfway there just to frustratedly shimmy them off. Mac takes the chance to get his own jeans off and relish in how nice it feels once his dick isn't restricted anymore. He only manages to get his pants off before Dennis is grabbing his hand and pulling him so fast to the bedroom that he almost falls.
They're falling onto the bed before Mac realizes they're in the bedroom and Mac is on top of Dennis and he is reminded just how wet he is. The smell of piss still permeates the room, poignant and stinging and oddly so insanely arousing.
Dennis makes quick work of removing Mac's underwear and getting his hand on Mac's cock and the simple touch sends Mac's stomach rolling and he moans.
"Jesus Christ, I'm so hard," he says as he tries to hold himself above Dennis on shaky hands.
"I can tell, baby boy," Dennis mumbles, stroking his hand up Mac's cock and resting his palm on his cockhead. "What did it? Me losing control, the smell of piss everywhere, our clothes soaked because I couldn't stop? Or was it making out with me while smelling my piss on yourself, feeling it cascade down your chest? Tell me, baby, I'm desperate to know."
Mac is at a loss for words for the longest time and he disguises it by getting Dennis's lips back between his own, then kissing down his jaw until he's at his neck. The entire time, Dennis has not moved his hand and it's making Mac's hips twitch.
The distraction doesn't work. Dennis's grip tightens and Mac gasps onto his neck.
"Answer me," Dennis demands.
"The first. I couldn't stop myself from touching you."
"I'm irresistible to you, even covered in my own piss. Pathetic, Mac."
"Shut up, I'm not the one who pissed his pants."
"I'm not the one who got off on it."
"Oh, really?" Though Mac is already having enough trouble holding himself up, he holds himself up with one arm and uses his other to grab Dennis's bulge, which causes Dennis's breath to audibly hitch. "Then what's this?"
"My gift to you."
"You're an arrogant asshole," Mac says, taking his hand off his bulge.
"Fuck my asshole."
"Gross, dude, don't say it like that."
"Shut the fuck up," Dennis says and Mac does. He stops so he can take off his shirt and then does the same for Dennis. He has an exposed chest to play with now and he wastes no time to kiss down his chest, not noticing until halfway down that the unusual taste he hadn't been able to place is piss and he thinks he should be mortified and disgusted but he's not sure he's ever been more turned on.
It's at that moment that he decides he needs to suck Dennis's dick or he's going to die. He may never again be able to taste him like this, so raw and open and trusting and Mac needs it, needs to know Dennis will let him keep touching him after showing so much vulnerability.
He reaches the bulge and almost cries because he had forgotten that Dennis still has his underwear on. But since he's impatient, he puts his mouth on the bulge anyway and is pleasantly surprised when he's reminded that fabric absorbs liquid and the taste is so much more potent here. Dennis gasps and his hips shoot upward and his hands fly to Mac's hair and Mac takes some time just to taste and, god, it tastes like nothing else he's ever tasted. People describe it like asparagus and Mac gets it, he truly does, but it's also nothing like asparagus. No matter what it can be compared to, it tastes like Dennis and that makes it absolutely perfect.
Mac is content to keep playing with Dennis's cock through his underwear, but eventually he pulls Mac's hair and forces him up and grits out, "Take them fucking off."
Mac obeys and is immediately on his cock the moment it springs from his underwear. He takes the head in his mouth first, cleaning whatever leftover piss is on the slit, then slowly putting the rest in his mouth, licking and cleaning it until he can't taste piss anymore, can only feel the saliva in his mouth.
Something hits him in the head and Mac pulls off, mumbling an ouch and rubbing his head.
"Sorry, I didn't mean to hit your head. Just, finger me, now. My stamina ain't shit anymore."
Mac takes that as a challenge. He finds that what hit him was a lube bottle and he squirts an overabundance on his hand and then realizes Dennis is in an awful position for fingering, so he repositions him, puts more lube on his hand, then takes Dennis's cock back in his mouth, down as far as he's able to. He lets it rest on the back of his tongue while he circles a finger around Dennis's hole, teasing it while also prepping it.
This isn't the first time they've fucked, far from it actually, they've done it a countless amount of times, but it's been a while. Mac has no doubt that Dennis has gone and fucked other men since they last fucked, the man is insatiable, but that doesn't make prepping him any easier.
He's begging Mac for more, talking again about his stamina, but Mac isn't buying it this time. He doesn't want to cause any pain, so he takes his time. However, he lets go of Dennis's cock so it can rest upon his stomach, and he focuses all of his attention on his hole.
Dennis isn't easy to stretch and he's been fingering him, making sure to scissor him, for at least ten minutes once he decides he can put in a third finger. Dennis hisses as he does it and suddenly he wraps his legs around Mac's back, the heels of his foot slightly resting on top of his ass.
"I haven't been stretched in so long," Dennis says, already out of breath.
"Yeah," Mac says.
"I want you to fuck me so hard," Dennis continues. He's usually not the most talkative during sex, but Mac isn't going to claim he dislikes it.
"How hard, Dennis? So hard you can't talk anymore?"
"Harder."
Mac twists his fingers and Dennis gasps.
"So all you can do is scream my name because it's all you can remember?"
"Harder."
"Hard enough you fucking piss yourself again? All over your bed, on the matress, so you can never fully clean it?"
"Yes, fucking yes, baby, that hard."
Mac removes his fingers. Dennis makes the filthiest noise Mac's ever heard, including the noises he's heard on the sex tapes. The hottest girl, the girl with the biggest boobs, the one with the nicest ass can't pleasure Dennis as well as Mac can. If that isn't the hottest thing to ever happen to Mac, then he doesn't know what is.
"Condom or no condom?" Mac asks because he's more than ready to just fuck Dennis already.
"I don't give a shit," Dennis responds. Mac hates wearing condoms so he isn't going to give up a chance to fuck him raw. He uses more lube though, has probably used half the fucking bottle, but he doesn't care.
Mac goes in slowly. Dennis is making a keening sound and doing his best to shove Mac in further with his legs, but he's forgotten how much stronger Mac is. Mac takes his sweet time to bottom out, pulling out slightly and going back in with each inch. Eventually though, after it seems like Dennis is going to kill him, Mac is all the way in. He rests for a second, mostly to tease Dennis than anything else.
Dennis tightens his grip around Mac's back.
"I hate you," Dennis grits out.
"You wish you did," Mac shoots back.
"I do! I hate you!"
"You want to keep arguing?" Mac threatens, fighting against Dennis's legs to slowly pull out.
"Don't you dare," Dennis says, and Mac smiles. He wants it to be mischevious, but he can tell it isn't. He knows it's because he loves Dennis too much. And because of his love, without warning, he slams into Dennis as hard as he can. Dennis absolutely howls and his back arches up, but Mac doesn't keep going at that pace. He's slow now, loving, he rubs his hands across Dennis's chest, running his hand up his cock. Dennis seems to be more satisfied with the consistent pace, even if it isn't hard and fast. Yet.
Mac knows what he wants to do. He's never done it before, but he's always wanted to. It's going to take time, but he has time. Dennis is going to bitch, but Mac doesn't care. Dennis wants it hard, Dennis will get it hard. Just not yet. Right now, Dennis is going to beg.
Mac takes his time finding Dennis's prostate, then he drags across it a few times, enjoying the sounds Dennis makes. It goes on like that for a long time before Mac drapes himself over Dennis and he repositions them both so that he doesn't have to pull out while he makes out with Dennis. It's hard to focus equal amounts of attention on kissing and fucking him, but the pace makes it slightly easier. Besides, Dennis seems to be thoroughly enjoying this. He's meeting Mac in the middle with everything he's doing, exerting as much energy as Mac is exerting himself.
"You're so good at fucking me," Dennis says, breaking apart the kiss to do so. He's out of breath and he has a dazed look on his face. A happy look.
"I know," Mac says, and kisses him again.
"You can go faster. You won't kill me."
"I know," Mac repeats, and true to the repetition, kisses Dennis again.
"So go faster."
"No. Not yet."
"What?"
Mac hasn't changed his pace throughout this whole conversation. He's barely pulling out before pushing back in as well.
"Well, I'm gonna make you cum like this. Then, I'm gonna fuck you fast and hard until you cum again, then I'm gonna keep going until I fill you up." Mac finishes his sentence with a particularly hard thrust that forces a breath of air out of Dennis.
"I don't think I can handle that."
"You can. You will."
"Fuck," Dennis swears.
Mac smiles.
He loses track of how long he has to fuck Dennis like that, making sure no hand gets on his cock, before Dennis starts acting like his orgasm is about to hit. He's gasping and twisting around and begging Mac for more, knowing he won't get it, and he keeps trying to wrap his arms around Mac's back, but Mac's just a little too far away, and so he has to settle on gripping Mac's biceps, digging his finger nails in as deep as he can, wanting to leave marks.
It's sudden once Dennis finally cums. He makes his already messy chest even messier, another fluid to dry on his skin, but Dennis hasn't even noticed because Mac is still fucking into him with no care to let him recover. He's begging Mac to give him a second, but Mac isn't listening, and on top of it, his speed picks up ever so much.
Mac adjusts his hold on Dennis, rests a hand on the pillow next to Dennis's head. His pace is increasing every few seconds, grunts escaping his lips, and Dennis is not sure he's ever seen Mac focus this hard, especially not while fucking. He'd tell him as much if he were at all capable of coherent words.
His second orgasm hits him just as he was wondering when Mac would finally let go himself. "Fuck, Mac," he screams. Mac doesn't respond. He pulls out and flips Dennis over so he's now laying on his stomach then he pushes back in all the way, letting himself and Dennis rest for a second as he kisses along Dennis's freckled back.
"You enjoying this, baby?" Mac says. It's muffled against his skin and he can barely make it out, but eventually, it sets in.
"Yes," he gasps out, but at the same time, Mac moves, shoving the side of his cock against Dennis's prostate, and Dennis is enjoying this, but he seriously can't take anymore.
"I'm very close. Gonna leave you leaking," Mac says.
"Gross," Dennis says.
"It's hot," Mac responds, then pulls out and positively slams back in. There is no possible way for Dennis to stop the whine that comes out of him.
The pace Mac sets next is ruthless. Nothing like he's done before. He's going at it so hard that Dennis can't keep the air in his lungs as he scrambles at the bed for any type of purchase, his legs tensing and his fingers clawing into the sheets. He's making choked noises everytime Mac shoves all the way in, his stomach is aching, and somewhere in his sex addled mind he thinks he's about to have another orgasm.
Mac's balls are slapping against Dennis's ass and it's echoing across the room so loudly that Dennis's camera and microphones are certainly picking up the noise. The noise becomes louder as he focuses on it, but Mac is thrusting harder as he tries to near his first orgasm and Dennis his third. Mac bursts first, filling Dennis as far back as he can push, and the pressure is enough to send Dennis over the edge again, and suddenly he can't see and he can't hear, all he can feel is the burning pain in his stomach and Mac's front draped over his back, pushing him down into his bed, and then he feels warmth around his stomach, but nothing he's doing is registering. He hiccups as he tries to catch his breath and calm his senses down without letting the weight of Mac crush him, but he also would rather die than make Mac remove himself. The monotony of Mac's lungs expanding and deflating across his back is helping calm him down, his heart rate evening out, the tears in his eyes drying and, unfortunately, the fluids around his crotch drying.
Once his mind is clear, it doesn't take much reasoning to figure out he pissed himself again after his last orgasm. His bladder hurts and is strained and he's not sure he's going to be able to properly hold his piss in for the next few days, but if pissing himself is what gets Mac to fuck him like that again... maybe he'll just have to do it more often.
He's half asleep and fully relaxed, Mac soft inside his ass, their breathing even with each other, when Mac moans against Dennis's skin and shifts his head to the side as he lays soft kisses across Dennis's shoulderblades.
"You know," he mumbles, "I kind of have to piss too."
Something in Dennis's stomach pinches and his mind starts to race. He's silent as he mulls over what Mac is suggesting.
"On me or inside me?"
Mac shifts and his dick twitches. "What do you want?"
Dennis has never done much with piss. He's always thought the concept interesting, and he's had at least one girl asked to be pissed on, but to be pissed inside of, to have his body used so disgustingly, to punish it for all the pain it's caused him... Who is he to deny Mac such a pleasure of feeling his own warmth around his shaft?
"Inside. I want you to piss inside me."
Mac moves up and places his lips against the back of Dennis's neck, gently kissing it and causing Dennis to shiver in his afterglow and expectancy.
"Are you sure?" he asks against Dennis's clammy skin, lips moving against the baby hairs on the nape of his neck. He's so rarely touched there, but he'll be dammed if it doesn't feel amazing.
"I can handle it," Dennis says.
"Okay." Mac leans up, leaving Dennis's neck cold as his hot breath leaves. His hand makes it's way from the top of Dennis's shoulderblades to the small of his back where he starts to gently message. His other hand wraps itself around Dennis's hip, his fingertips digging into the thin skin and pushing into the bone. He spends a while willing himself to relax and stay soft, as hard at it is, but eventually he feels his bladder start to release its contents, the heat spreading across his dick and making it basically impossible for him to keep his interest at bay as his dick starts to harden and his flow tapers off as his body prepares to ejaculate again. Without thinking about it, he starts to thrust again, feeling the liquid slosh around inside Dennis, and he never thought he'd fuck into a body filled with his own piss, but with how much he enjoys this, he doesn't think it'll take him long to finish. Which, judging by how Dennis lays bonelessly pressed against the matress, he's not going to be able to take much more. Mac sets a slow and uncoordinated pace so as to not overstimulate the man worse than he already is.
Barely any time passes before Mac has another orgasm, his hips twitching upwards into Dennis. He breathes heavily as he comes down from his second, unexpected, high, spreading his fingers out on Dennis.
"I should pull out," Mac says the moment he's able to catch his breath enough to do so. Dennis manages to hum something that could be words if his mouth wasn't smushed against the mattress. Mac is gentle when he leaves Dennis's body, slow and careful, but he can't help but, with his thumb, push in the various fluids that leave his ass with Mac's cock.
He falls next to Dennis, on his back, and allows his eyes to shut. He's almost asleep when he feels Dennis start to shift until he's on his side. He drapes a leg over Mac and wraps his arms around Mac's chest. Mac, eyes barely cracked open, looks at Dennis's relaxed face, his mouth slightly open to take in and let out air, and Mac smiles.
"You're going to leak on your bed," he says.
Dennis doesn't bother opening his eyes as he responds, "We'll shower soon."
"Together?"
"Yes. Then we'll clean up our tremendous mess."
The prospect of cleaning their mess doesn't intimidate Mac. All he can think of is showering with Dennis, washing his hair, running soap over his smooth skin, watching water droplets trail down his body. Something he's never had the pleasure of doing, but has wanted for years.
"Let's do it soon," Mac suggests, but by the lack of a response, he's sure Dennis is already asleep.
Before Mac is asleep, he reminds himself to get the hundred dollars for the bet from Dennis.
