Heartbeat

Summary:

“Wait–where's the women?” Dennis grabbed Mac’s arm, stopping him in his tracks.

“I lied.” Mac smiled. And just before Dennis could go off on him, he was distracted by Mac getting uncomfortably close, breath puffing against Dennis as he leaned in. For a moment, Dennis thought Mac was going to attempt to kiss him again; instead, a hand reached into his back pocket, stealing his keys. “You’re staying, better find a way to entertain yourself! Love you, bro!”

Mac convinces Dennis to go to an orgy, but once he discovers this is an all gay event, he sits and waits for Mac to be finished. And discovers a way or two to keep himself entertained as he waits.

(AKA, Mac gets a train run on him, and Dennis watches while seething with jealousy.)

Notes:

Wanted to write more Mac triple penetration, it's a shame I'm the only one so far that's written him being triple penetrated. (As far as I'm aware.) But I don't ship anyone else with him besides Dennis, so unnamed men that are barely mentioned besides their cocks it is!

(See the end of the work for more notes.)

Work Text:

“Dennis, please! It’ll be fun, and I don’t want to go alone!” Mac whined as he trailed behind Dennis, making the process of brewing coffee so unbelievably insufferable.

“I already told you, I’m not gay! Why would I want to go to some weird gay sex party?” Dennis scoffed—it’d been years, but he still remembers the orgy he and Frank went to, all disgusting old fat people just eating food half naked. The only way he thinks that situation could get worse is if they were all old, fat gay guys, and Dennis, being fit and younger than anyone there, would be hit on a disgusting amount.

Mac got uncomfortably close, and Dennis knew he had more of a motive for inviting Dennis than just not wanting to ‘go alone’. “There’s gonna be girls there, I’ve seen some of them, they’re hot.”

“I don’t know if I trust a gay man’s opinion on what girls are hot or not.” Dennis rolled his eyes as he poured his coffee, making sure to turn and intentionally smack the burning hot pot against Mac’s arm.

“Dude!” Mac yelped, and that made him back up quickly. “Come on, just try it out, you might like it.” He whined again; that tone of voice drove Dennis crazy, and not in a good way. He hated when Mac used it on him, and he hated that it was beginning to wear him down.

Dennis wasn’t doing anything tonight, and he was long overdue for a hook-up—maybe this wouldn’t be so bad, if he could avoid all the gay guys. “If I agree to check it out, will you leave me alone?”

“Yeah! Wear something sexy, okay? You don’t want to show up in jeans and a button-up.” Mac punctuated the sentence with a small slap to Dennis’s ass; there it was. Mac’s motive. Ever since coming out as gay a year or so ago, he’d become so fucking bold, coming onto Dennis at any opportunity he could. Dennis couldn’t count how many times Mac’s tried to kiss him, how many times he’s succeeded.

“I’m always sexy,” Dennis grumbled, taking a slow sip of his black coffee—he liked cream and sugar usually, but if he was going to be naked in front of a group of people, he wasn’t going to be bloated.

Mac bit his lip, looking Dennis up and down; he wasn’t even trying to hide it. “I’m not having sex with you, I’m going for women,” Dennis added, and Mac quickly nodded, even if his face was saying that he wasn’t believing Dennis’s very clear rejection.


The car veered into the wrong lane for the third time during this drive; Dennis would blame it on the alcohol mixed with the dark roads if Mac asked. But truthfully, Dennis found himself oddly distracted by Mac’s outfit. Tight mesh shirt, and the shortest shorts a man could possibly buy without them being from the women's section; it made Dennis feel overdressed. His old jorts that he’d kept after all these years, despite never wearing them, looked like capri pants in comparison to Mac’s, and his shirt didn’t reveal nearly as much as Mac’s shirt did–if it could even be called a shirt.

“So, what’s the point in dressing up if it’s all going to come off anyway?” Dennis questioned, using all the force in his body to draw his eyes off of Mac’s beautifully pink nipples peaking from the mesh and back onto the drab road.

Mac shrugged. “What’s the point in plating food all fancy if you’re just going to eat it anyway? It’s about presentation, Dennis. Gotta make them hungry first.” For a man who managed to barely pull anyone pre-coming out, he seemed to suddenly be smart about attracting lovers. Maybe he truly did hate banging women all that time. Even if Dennis had his doubts, he couldn’t look past the facts; Mac’s had more partners in the past few months than Dennis has probably had his entire life, and that’s saying something.

“They’ll be hungry when they see my seven-incher,” Dennis commented, being rudely spoken over by the Google Maps mid-sentence.

“Bullshit, you are not seven inches,” Mac scoffed. “Don’t act like I haven’t seen it a million times.”

“I guess you would have a lot of experience in telling cock sizes, wouldn’t you?” Dennis bit. Mac could bang as many people as he wanted, Dennis didn’t care, but it got to a point; he was overly compensating for not being gay all these years, it was desperate and degrading, but maybe Mac liked that.

“You can’t slut shame me when you’ve brought a million barely legal girls back to our apartment!” Mac shouted.

“Hey–They’re not ‘barely legal’! I just don’t bang old women, unlike you, remember when you fucked my mom?” Dennis was already getting fired up; he wasn’t going to have fun at this party with Mac riling him up like this–maybe he’d have some beautiful woman to fuck his anger into, some girls like it rough like that.

“Yeah, yeah, whatever makes you sleep at night…Pervert.” Mac mumbled, snark being quickly replaced when Dennis grabbed at his arm and clawed.

“Have fun being presentable with a big ol’ scratch on your arm, asshole.” Dennis slapped his hand over the wound to spread that burning heat up Mac’s arm, taking satisfaction in the way Mac breathlessly whined, attempting to mouth something but failing.

The ‘you’ve arrived’ rang out from Dennis’s phone; shockingly enough, the entire driveway of the house was full, and most of the road–Dennis had to park his rover across the street. “I don’t want your gay friends thinking I’m one of you, so we’re splitting up—I don’t know you.”

“Okay, whatever, dude,” Mac replied, nervously pressing at the scratches on his arm, wincing at every touch. “That really hurt.”

“Good.” And with that, Dennis was getting out of the car; he still wasn’t super excited to discover just how ugly these women were, but anything was better than chills going up his spine from Mac’s whiny voice.

Mac quickly caught up, joining Dennis’s side despite his comments about not knowing each other. When they entered, Dennis was surprised; pleasantly for a moment, seeing as there wasn’t a buffet surrounded by half-naked guys in masks. But suspicion flooded him when he had a hard time spotting anyone feminine, let alone a woman—he mistook a twink with long hair for a woman at first glance, but so far that was as close as it got.

“Okay, well, I’ll fuck off,” Mac whispered in Dennis’s ear, and it made Dennis jump. That deep whisper tickled his ear in a chilling way; it shouldn’t cause blood to flow straight to his dick, but he felt a little throb just below his shorts.

“Wait–where's the women?” Dennis grabbed Mac’s arm, stopping him in his tracks.

“I lied.” Mac smiled. And just before Dennis could go off on him, he was distracted by Mac getting uncomfortably close, breath puffing against Dennis as he leaned in. For a moment, Dennis thought Mac was going to attempt to kiss him again; instead, a hand reached into his back pocket, stealing his keys. “You’re staying, better find a way to entertain yourself! Love you, bro!”

And then Dennis was alone, standing in a room full of mostly naked gay guys; he felt like a gazelle dropped right into a lion's den with the eyes peering at him curiously. If he were really determined, he could walk home or beat Mac’s ass and grab his keys back, but it all seemed like too much effort for what was going to be a quick one-and-done. Mac would bang some dude, and then want to leave because he’s forty and can’t possibly get it up again fast enough.

Luckily for Dennis, there were a few seating options in this living room, though it seemed most of them had been moved out or rearranged to make it more ‘sex-friendly’. He felt like a cuck, sitting in a love seat off in a corner, staring at Mac chatting up a random guy; at least he’d already found someone, and this would be over quickly.

What Dennis didn’t expect, though, was when Mac started removing his shorts, another man came up behind him—two at once? Dennis tried his best to avoid Mac’s sexual endeavors once he came out, had absolutely no interest in hearing about Mac banging dudes, so he was clueless about Mac enjoying multiple partners at once.
It seemed fitting, seeing as Mac was such a slut; usually Dennis stuck to his room when Mac had men over, but he’s heard a thing or two, and maybe he should have guessed there was more than one man in Mac’s room.

There was this awkward feeling in Dennis’s gut as he got a full view of Mac’s ass; it shouldn’t feel wrong, Mac invited him here knowing full well he’d get naked in front of Dennis at some point, yet Dennis still felt his breathing pick up. Mac had been working out lately, more so than he usually does; he still had that cute full face, but Dennis had taken note of the way his arms filled out ever so slightly, and it seemed his ass had gotten a bit of that definition as well.

Pleather peeled from the armrest, sticking to Dennis’s sweaty skin; why was he sweating so much? There was definitely an air conditioner somewhere in here; it didn’t feel particularly hot, yet his face felt flushed.

A possibility flashed in Dennis’s mind, a disgusting nonsense reality that didn’t align with how Dennis had presented his entire life—it could be Mac making him feel flustered like this. He really shouldn’t, he never has before, save for the rare few times he and Mac got oddly flirtatious before he came out, but that wasn’t often.

“You want a popper, sweetheart?” One of the men asked Mac, and Dennis narrowed his eyes, making sure what they held up to Mac was just a popper. It’s not that he cared all too much if Mac got given something stronger; knowing their track record, Mac would probably want to. But part of Dennis felt the instinct to protect Mac, if not only a little bit.

Dennis might have the wrong notions about Mac's sexual preferences, because the man standing behind him was pouring lube on his hand, not Mac’s—for someone who topped women for decades, Dennis would have assumed that’d transfer here.

When Mac sniffed at the small bottle in front of him, Dennis could see the shiver overtake his body; though upon further inspection, it didn’t seem to be from poppers alone.

“Not interested,” Dennis immediately blurted out when a man tried to join him on the love seat; he had one man on his sights, he didn’t have time for an experiment. It wasn’t weird that he was watching so intently, that’s what Dennis told himself as he eyed the two fingers entering Mac.

It was simple curiosity, Dennis wasn’t one to shy away from taboo subjects–even if he had so many times when it came to Mac. This time was different, though; something about Mac’s panting, flushed face drew him in like someone seeing the Mona Lisa for the first time. He was a work of art while moaning, and Dennis never knew until now.

At first, it was easy to ignore the other men's existences, but as they maneuvered Mac onto his knees, it was getting harder to pretend it was Mac and Mac alone.
The moment a cock was gestured in front of Mac’s lips, his mouth dropped open, so obedient without even being asked. Dennis had to uncomfortably shift his legs around as he watched, crossing them to hide his boner even though there were numerous people around him having full-on sex. It didn’t feel right, being so turned on by seeing Mac getting a mouthful of cock, and yet he kept his eyes locked on.

Mac’s back curved, arching that gorgeous ass up as he took the dick deeper in his mouth. A flicker of something hit Dennis as he watched that, the way Mac’s mouth spread to accommodate it, his look of content as he stared up at the man, even the gentle way that stranger held Mac’s chin, guiding him. Flickers of feelings, ones of which Dennis never gets and didn’t quite process in the moment, kept hitting at every action. Worsening when the man behind Mac pulled his hand away, quickly replacing it with his dick.

Tears pricked up in the corners of Mac’s eyes, struggling to keep up as both men buried to the hilt, that is, until he flicked his eyes around the room, finally landing on Dennis. It was like a switch flipped in Mac, tears blinking away as he locked onto Dennis.
That stare was disgustingly intimate, and even with a cock shoved to the back of his throat, Mac attempted to smile, the gesture barely making it past his propped-open mouth.

That look, like he knew Dennis was staring for more of a reason than just simply looking around the room, was affecting Dennis. It stayed locked on Dennis, glaring into his soul, until a gag wracked his body, and then he was locked back onto the man in front of him, like he’d just remembered he existed. It served the bastard right; he shouldn’t be giving Dennis flirtatious glances while getting deep-throated by another man's cock.

Mac himself had invited the staring, ‘find a way to entertain yourself’, well, he’d found it. There were people having sex independently, of course, other bodies to stare down, but Dennis's eyes stayed plastered on Mac.

He’s never seen dick sucked from this angle before, and he had to admit it was a thrilling one; from the side view like this, he could see Mac’s throat contract with every movement, moans catching in his mouth from every thrust in his ass. And when Mac suddenly let out a loud groan, Dennis’s eyes snapped right back to his mouth—that dick was buried right to the hilt, Mac’s nose scrunching from being shoved into his pelvis, and from the way his throat bobbed repeatedly, the man was finished.

Dennis was almost disappointed at that, as much as he wanted to leave, part of him wanted to stay and watch Mac being fucked like this for longer; that sight of the man pulling back, leaving obscene strings of spit and cum snapping down onto Mac’s chin was one Dennis wanted tattooed on the forefront of his mind, replaying like a favorite movie. If he had been smart enough to bring a camera to this, he’d have rated Mac at least three stars, four if points hadn’t been docked for the fact Dennis wasn’t the one fucking him.

Now that his mouth was free, Dennis could hear his grunting more clearly, body lurching forward with every rough thrust–these men weren’t nearly as gentle with Mac as they should be. He paraded himself with that macho persona, acting like he could take on anything, but Dennis knew him; he knew this was way too intense for Mac.

And maybe he was doubting Mac’s strength, because it seemed like he was the life of the party. Another man was making his way in front of Mac, where the previous had left, and Mac greedily opened his mouth without even looking up to see who was trying to get their cock in his mouth. And who could blame them? Mac was the most attractive man here, and that’s not Dennis being biased.

In his completely professional opinion, most of the men weren’t hideous, but they didn’t have the same long eyelashes framing perfectly down-turned eyes, none of them held a little extra fat in their face from being overweight, filling out their cheeks in the cutest way–even if some of them were fat, it didn’t look nearly as good as it did on Mac.

Dennis blinked. Was he really admiring Mac? He was starting to question if the drugs people were doing had gone airborne, because this wasn’t normal. Bros could admire bros, but Dennis was doing it with a boner and a slight tinge of jealousy as he watched Mac’s cheeks suck in around that dick.

Hands were suddenly wrapping around Mac’s waist, drawing him in close as the man behind him shoved up against him—were none of them wearing condoms? Dennis didn’t like condoms all too much himself, but Dennis also wasn’t getting came in. When that cock pulled out, dripping just a bit of cum onto Mac’s ass, most of it having ended up inside, Dennis feared for the safety of his Range Rover; Mac better clean himself up if he expects Dennis to drive him home.

Dennis almost got up and put a stop to this when two men who were previously jerking each other off took note of Mac, making their way across the room–Mac needed to be finished, there’s no way that he can bang five men in one night. If Mac wasn’t going to be a voice of reason in this, then Dennis would have to be for him.

But as Mac pulled the cock from his mouth, eagerly looking up to hear what the men were saying, Dennis found himself staying plastered in place. If Dennis were in this situation, he'd be intimidated, uncomfortable even. But as the two men got closer, whispering things to Mac, he seemed excited. A smile began to form on his face as he nodded in agreement.

Something in Dennis kept him there, a sick desire to see that look of utter excitement to slut himself out on Mac’s face; if anything, he wanted to get up now just to take Mac for himself—What’s wrong with him? Dennis smacked the side of his face; he was burning hot, shockingly, the blood pumping to his crotch hadn’t forgotten to melt his face as well.

“Oh, please, of course I’ve done it before,” Mac scoffed as he stood up. His voice sounded scratchy, for obvious reasons, sending chills down Dennis’s spine. For a moment, Dennis had the innocent assumption that one of the men would be waiting, considering Mac only had two holes.

Mac instructed one of them to lie on the floor, quickly climbing on top of his waist; it reminded Dennis of a position they’d been in before, attempting to pin each other down mid-fight numerous times, only Dennis hadn’t ever considered that Mac could be lowering himself onto Dennis’s cock while they did that.

Someone's talking from Dennis’s side buried the beautiful moan Mac most definitely let out, head rolling back as his mouth popped open. And Dennis would have turned to punch the person if not for his remembering he was at a ‘party’ and Mac wasn’t the only one there, even if he was the only one Dennis’s eyes could focus on.

Mac has never been as attention-grabbing as he was right in this moment; it’s like he had a certain sparkle to him, which shouldn’t be the case, no man should be this beautiful while being fucked. Apparently, Dennis was too naive when it came to gay sex, because the other man was, in fact, not waiting.
When Mac got down to the base of the first cock, the other lined up behind him; that’s all they were to Dennis, spare cocks, they didn’t matter as much as Mac did. And if Dennis acknowledged them more than the amazing faces they were drawing out of Mac, he might scream out of some weird mix of sexual frustration and jealousy.

Never once has he felt jealous over Mac, but then again, he’s always had Mac to himself. He was safe in the way he didn’t have an option other than Dennis, always taking Dennis’s sloppy seconds, never really pursuing.
And when he did, Dennis wasn’t up close watching someone else reap the benefits of Mac. The only times he’d seen Mac be sexually pleasured, it was from Dennis, whether it be him trying to be sneaky about masturbating to Dennis’s ass on the tapes, or him full on watching Dennis while he banged a chick. Maybe Dennis wasn’t so weird for watching after all.

There was that flicker of intimacy, though. Because when Dennis had sex, he never looked at Mac, but here Mac was, eyes drawing back over to Dennis as he let out a groan. A hand ghosted over Mac's neck, presumably the man currently stretching Mac beyond his limits–god, Dennis has never had the pleasure of encountering such a whore.

With every thrust, Mac shook forward, a new moan escaping his lips; he had to be doing that on purpose to drive Dennis crazy. His suspicions were confirmed when Mac sat up straighter, thrusting himself right back onto the man hitting him from behind; his stupid hand rose, giving a small wave to Dennis, he was doing that on purpose.

Dennis looked away momentarily, and with his eyes tracing the stained carpet, he could push away the feelings. In, out, in, out, he puffed his breath heavily, trying to expel emotions from his body with each exhale, but all the in and out visualization in his head was making him think of Mac’s situation.

Another hand made its way to Mac’s hair, guiding his face back to the cock that’d previously been in his mouth; three at once, Dennis had definitely underestimated him. That hand gripped his hair so tightly that Dennis was sure they were going to pull strands of that precious, deep brown straight from his scalp.

Sure, Dennis had a knack for being rough during sex, but this felt different. Instead of degrading a random girl, this felt like Dennis’s personal property was being vandalized; he didn’t own Mac, but there was always that layer of commitment between them, something Dennis wouldn’t just let be tarnished and treated so roughly like this.

Mac didn’t seem to mind, though, allowing himself to be guided forward; his eyes never left Dennis as he darted his tongue out, giving a slow, sensual lick to the underside. Even while surrounded by other men, Mac was flirting with Dennis.

It was almost exhilarating the way Mac was focused solely on him. None of those guys knew Mac was putting on a show for Dennis, distracted by a man not even practicing rather than the ones literally inside of him. No one would ever have Mac like Dennis did, which gave him a little solace. Mac was wrapped around his finger.

He’d humor it, if not for his own sanity. Dennis lifted his shaky hand, giving a small wave back, and at that, Mac’s eyes widened, suddenly denying the little flirtation.
Any eye contact was severed when Mac jolted forward, eyes suddenly squeezing shut as his mouth dropped; Dennis couldn’t appreciate that desperate moan racking him because the man in front of Mac took that as an opportunity to thrust inside. Mac’s moan hadn’t been something in passing; his hands shook as they darted up to the man’s hips, and Dennis could see the lines of white shooting on the man below Mac.

Dennis dug his nails into the armrest, Mac came, and the bastards didn’t even give him the satisfaction of touching him. It wasn’t long until the man thrusting into his mouth had his load join the firsts, straight down the back of Mac’s throat. Did they all have to do that? Apparently, Dennis wouldn't have to order dinner tonight, seeing as Macs swallowed enough semen to make a thousand children.

After pulling out, Dennis didn’t have a moment to appreciate Mac’s panting mouth, the man quickly leaning down to kiss Mac, getting his disgusting face in Dennis’s perfect picture.
His nails scratched deep. Whoever owns this chair was going to be pissed because he was destroying it with the seething anger of watching another man french Mac. That is, until a new person came up behind them, catching Mac’s attention—six.

Fucking—six? Dennis was pulling the plug on this. Mac clearly wasn’t thinking straight if he was just going to sit there and let a sixth man enter his body in what…an hour? Not even, it’d been like forty minutes. His legs felt tingly as he stood up, and his boner was clear as day in his shorts, but he made his way over regardless.

“He’s done, fuck off,” Dennis bit, shoving the two men away from Mac’s face. “Get up.”

“Wha–Dennis-” Mac stuttered, and the two men in his ass were giving him such a look, as if they had the right to use Mac like this. Dennis grabbed at Mac’s arm, rough enough to pull him right up and off of the men below and behind him; this time, Mac’s moan was so clear.

“Dennis! Jesus, dude! What’s your deal?” Mac huffed, wobbling to his feet as Dennis forcefully helped him up.

There were numerous voices of complaint from around Dennis that he couldn’t give two shits to hear out. “Get on your shorts, we’re leaving.”

Mac gave him an odd look, but grabbed his shorts and underwear off the floor anyway. “I need to…use the bathroom.” He mumbled, and Dennis tried to ignore the wetness that was most definitely dripping down the back of Mac’s thigh.

“Yeah, whatever, okay,” Dennis whispered in return, and off Mac went, so fast—has he been here before? Just how many times had Mac been fucked like that? Dennis felt his eye twitch a little; he didn’t want to think about that.

“Hey, dude, you don’t own him.” One of the guys said, and Dennis didn’t even give him the pleasure of eye contact. He knew nothing, and he was simply an extra in this anyway–Dennis didn’t care enough to acknowledge his existence. Background characters don’t talk to talent, and Mac was the star of this room; they needed to learn their place.

Finally, Mac emerged from a hallway, dressed, but still so messy. His face was flushed, hair all tossed up, Dennis felt his boner stay full pressed against the zipper of his shorts, Mac was enchanting tonight in a way he didn’t get.
Before any man could convince Mac to stay, Dennis grabbed him by the hand, quickly walking him outside; he tried not to take note of the way Mac stumbled over every step, grimacing a little, clearly struggling to stay upright.

“Slow down, dude!” Mac whined, and for once, Dennis would listen. Only because they had already made it outside, and Dennis no longer had to worry about sharing. Even if Mac was willingly following, Dennis kept their hands locked together until they reached the car. It was a nice reminder Mac wasn’t actually into any of those men, because he didn’t hold hands with them.

The drive home would be even more dangerous than the ride here; he’d sobered up slightly, but his eyes only wanted to follow Mac. He was shifting in his seat, clearly uncomfortable sitting, yet he had this crude look of satisfaction on his face. As he looked over Dennis, that look only furthered, a smirk pulling at his lips.

“Did you enjoy the show?” Mac questioned, hand clutching at his stomach even as he tried to stay flirtatious. Dennis felt his face heat up at the acknowledgement of his perversion.

“I didn’t enjoy watching a ton of men having sex, no.” Dennis tried to keep his eyes focused on the road, but Mac was making it so hard. His breath hit Dennis’s neck as he leaned closer, reminding Dennis of the warm, inviting mouth on him—so fucking experienced now.

“I saw you watching me, Dennis. You weren’t eyeing anyone else in that room,” Mac whispered, sending a chill down Dennis’s spine. “And you’re telling me that boner on you means you didn’t enjoy it?”

Dennis was moments away from crashing them into a tree when Mac’s hand ghosted over his bulge. “I didn’t fucking enjoy it, seeing you being covered by other men, why would I enjoy that?” Dennis bit.

“You’re jealous!” Mac beamed, but even with the realization, he sank back in his seat, taking his hand away from Dennis’s crotch.

Dennis bit his lip. Suddenly, the road felt compelling, better than admitting that he was so damned jealous. He wanted to be the one making Mac feel like that, because no other man deserved Mac in the ways Dennis did. That’s what it took to make Dennis realize he didn’t want Mac going after anyone else? Seeing Mac being penetrated by numerous men? You’d think he’d have figured that out without having to see the ways Mac would degrade himself for satisfaction.

“Don’t get all mad, I’m too tired for a fight.” Mac punctuated with a yawn. “It’s cute, though.” That little added mumble released something in Dennis; he wasn’t sure if it was butterflies in his stomach or anger rushing back through him.

Mac didn’t get to do that; he didn’t get to enjoy Dennis’s feelings. If not even Dennis could enjoy them, Mac sure as hell shouldn’t. The apartment couldn’t come soon enough, but it also seemed to fast; it loomed over him, and Dennis knew it was a bad omen. He’d have to confront whatever this was, and confronting it meant doing something with Mac, which he’d so adamantly denied; Mac didn’t seem to be complaining with his little flirty looks, though.

When they started walking in the building, Dennis grabbed at Mac’s hand again. He didn’t care if they were the only ones in the lobby; he needed some sort of proof that Mac wasn’t going to run off with someone else.

“I’m not hiding any men in my bedroom; you can stop being jealous now.” Mac attempted to sever the contact when they reached his door, but Dennis wasn’t having any of it. Confront.

Dennis shoved Mac up against the door; unlike the men at that party, he didn’t ask first, because he already knew the answer. There wasn’t any sort of discussion needed when Dennis already knew Mac inside and out, so disgustingly close in a way none of those men could understand. He almost wished they were still at the orgy, so Dennis could slam his lips against Mac’s mouth like this in front of all of them. Show them just who Mac belonged to. ‘You don’t own him’, bullshit, as if Mac hadn’t been Dennis’s since the start.

It didn’t take more than a moment for Mac to reciprocate, legs like jelly as he grabbed onto Dennis to support himself. That’s all he was, putty under Dennis’s touch, melting in a way he hadn’t for anyone else. Dennis might just be stroking his own ego at this point, because he’d only seen Mac having sex once—maybe he always melted like this. It was a bold assumption, but what was Mac if not bold? Dennis was simply matching his energy.

Dennis worked his tongue in, giving the deep kiss a go for a moment before pausing; that taste–. It’s not like Dennis hasn’t kissed someone after they’ve eaten or forgotten to brush their teeth before; he wouldn’t care that much, but this was different. He was most definitely tasting another man's cock right now—or rather another man's semen.

He pulled back, eyeing Mac’s mouth with slight disgust. “Go gargle with some mouthwash.”

It was a good show, but that flavor was a not-so-gentle reminder that Dennis was just taking the sloppy seconds–thirds—forths? Fifths, that sounded right. Dennis hadn’t been paying all too much attention to the men fucking Mac themselves, and even if he’d been counting before, he’s mostly blanked them out of his mind. He only cared about one of the men there, and it was a certain puppy-dog-eyed slut.

Mac blinked, practically having sparkles in his eyes as he stared at Dennis breathlessly. “What?” He seemed to be snapping back into reality, too caught up in kissing Dennis to have even fully processed what was happening.

“Your mouth tastes like cum, idiot.” Dennis smacked the back of his head, and Mac grimaced with embarrassment before quickly making his way to the bathroom in Dennis’s room; perfect placement, seeing as it’s where Dennis wanted him anyway.

When Dennis peeked into the bathroom, he could see Mac vigorously swishing mouthwash, so desperate for Dennis’s kisses, and if that wasn’t doing something for Dennis. “Hurry up, Mac.”

Mac quickly spit—which was a change of pace from the rest of the night–and made his way back to Dennis’s arms, where he rightfully belonged.

“You wanted to make me jealous, didn’t you? You’re such a piece of shit, you know that, right?” Dennis questioned as he shoved Mac onto his bed, drawing a little pained gasp from him.

“So what if I did? At least it finally made you realize how obsessed you are! You’re always fucking–ah!” Mac cut off his sentence with a whine when Dennis crawled between his legs, giving a mindless thrust against his clothed ass.

“What was that, Mac?” Dennis was taking advantage of the soreness to cut off Mac, but that seemed to determine Mac even more, voice rising with the next go.

“Always manipulating me! You ran away with your stupid fling to North Dakota just to come crawling back because you’re obsessed with me,” He panted out, each word having to force its way past a whine as he attempted to squirm away from Dennis’s movements.

“You’re one to talk!” Dennis huffed, pinning Mac’s waist down with one hand, using the other to unbutton and tug off his shorts.

Mac’s ass looked nice like this, even more so than it had before, lying under Dennis rather than being touched by other men. Dennis didn’t waste time tugging down his own fly, popping his cock through the hole.
Considering he had three men in his ass, Dennis assumed Mac prepped enough; still, when Dennis spit in his hand and made haste getting inside the pinned man, Mac still let out a loud groan.

“Fuck, Den! Slow down!” Mac repeated for the second time this night, and maybe Dennis needed to go easier on him, a man would be sore after taking so many damned cocks—at that thought, Dennis didn’t want to consider slowing down anymore. He wanted to give Mac that same rough treatment he so despised in the other men, show him how a real man does it, show him who owns him.

“You sure as hell weren't telling those other men to slow down,” Dennis huffed in his ear, wrapping arms around Mac’s waist to pull him as close as he physically could; he wanted Mac to forget all about how those other men felt, overload his senses with just Dennis’s touches.

“That's different! They weren't you—I want to actually savor this!” His hands slid onto Dennis’s shoulder blades, nails digging into Dennis’s shirt, punctuating each word with a sear of pain across Dennis’s skin.

At that request, Dennis nearly stilled. That’s what he needed to hear; all those quick fucks were meaningless and quick until it came to Dennis. “I want you to block whoever invited you to that,” Dennis instructed, and he could feel Mac’s stubble scratch his face as he nodded.

“Okay—ah-yeah, I’ll do that.” So obedient, it was just in Mac’s nature to submit, wasn’t it? Basically any man that came his way could get him to his knees, and Dennis probably shouldn’t be going at this raw, considering. But he’d be damned if he didn’t prove himself better than the other men as soon as possible.

A yawn followed Mac’s words, and Dennis began to notice just how lazily he was holding on–no wonder it was hard to hold his waist up, his legs were practically limp. “They really wore you out, yeah?”

“Mhm,” Mac mumbled in return, a hand letting up on the scratching to instead thread into Dennis’s hair. “I didn’t rinse out my mouth for nothing, kiss me.”

Dennis got in close, not quite sealing their lips. “Am I better than them?” It’d sound insecure coming from anyone’s mouth but Dennis’s.

“Way better,” Mac whispered back, and when his head leaned up to try and capture his reward, Dennis pulled away. “Please.”

“Say you’re mine,” Dennis demanded; Mac could have what he wanted after he gave Dennis a little something, the prize being Mac himself, complete and undivided just for Dennis.

When Mac failed to comply, Dennis sat up fully, getting a good look at Mac’s face. Untrusting, suspicious of Dennis in a rightful way, this was quite the change of pace, at least verbally. In a way, Dennis has always thought like this.
Mac was his second half, more of an extension of Dennis rather than a separate being. Or maybe Dennis was the extension of Mac; it was hard to see where the lines blurred between them. He really thought he was making a clear cut and solid line by abandoning it all, but if anything, it’d only furthered the distinct melting of them.

Dennis held his hand over Mac’s throat, not applying pressure, simply holding him captive. A possessive action that had Mac whimpering. “I’m yours.”

“Good,” Dennis acknowledged, and for that, Mac could be rewarded. He captured Mac’s breathy whine, pulling it into his mouth with the kiss, reaping the vibrations caused by his praise right across his tongue.

Dennis returned both his hands to Mac's waist, and with his nails digging in, he wished he had more precision. If he weren't so shaky, jostling both of them with each slow thrust, he'd be more artistic with the marks. Clawing in a 'Dennis' right along Mac's hip bone, maybe leading to his penis, anything to show Mac's next hook-up that there would always be someone else on his mind, even if he was banging them.

In all honesty, he didn’t even have to claw it in. Mac could be easily talked into marking himself just for Dennis; he was so susceptible to Dennis's words. If he prompted, Mac would probably add his name to his collection of shitty tattoos.
At the thought, Dennis pressed his hips closer, dragging his nails down until they left marks all the way down to Mac’s thighs; the loud whine of pain that erupted from Mac was like music to Dennis’s ears.

“If you try to fuck another guy, they’re going to see that you’re mine,” He began, rubbing a finger up one of the scratches, a beautiful reminder of why Dennis kept his nails a little pointed.

Mac reached a shaky hand down, grabbing the one irritating the wounds. “Why would I ever fuck another guy if I have you?”

Right, Dennis had forgotten that most other guys were simply a temporary replacement rather than a permanent part of Mac’s life. None of them were so consistent in his life like Dennis was. Dennis didn’t have a chance to reply, instead pressing his hips as close to Mac as he could, a desperate attempt to meld them together like they had been for years, only physically this time. He hoped he reached deeper than anyone else as he came in, Mac, purposefully tugging Mac’s thighs up to get the deepest angle he could manage.

Mac grabbed Dennis’s hair roughly, and Dennis would reprimand him for messing up his curls if not for the kiss he was being tugged into. A pathetic attempt at a kiss, that is, lips connecting and disconnecting as both of them moaned into it; it seemed Dennis wasn’t the only one finishing. In the end, Mac had managed to fuck six guys in one night after all, Dennis hadn’t prevented shit.

Having sex with that many people didn’t come without its faults, it seemed. Because when Dennis pulled out and sat up straight, Mac was practically limp against the mattress, shuddering breaths the only movement coming from his body.

“Go to sleep, okay? I’ll clean you up.” Dennis would treat him gently, in spite of what he’d just clawed into Mac’s hips; he still had to prove himself better here, and he could guarantee none of those guys Mac hooked up with cared to perform aftercare.

“Hm,” Mac simply hummed in acknowledgment, stretching out to get comfortable on Dennis’s bed.
Dennis made haste with grabbing Advil and a washcloth—being away from Mac’s heat felt like torture against his quickly cooling skin. When he got back, Mac was already passed out, snoring in a way Dennis would usually find annoying, but right now it was almost endearing.

He quickly wiped Mac down, discarding the pills to the bedside table in favor of not waking Mac.
That mesh shirt was already leaving imprints of fishnets across Mac’s pecs, so Dennis carefully pulled it off for him; Mac looked so soft like this, abs defining nicely, but soft, at peace sleeping in Dennis’s bed.
In the darkness of the room, shielded by Mac’s exhaustion, Dennis leaned in, planting little kisses across his torso, taking careful watch of the way Mac’s breathing picked up ever so slightly. He was cute, really, and Dennis was sure that was the first time he had thought that of Mac.

“Mine,” Dennis whispered against one of Mac’s pecs, the word vibrating against Mac’s skin in the best way. Dennis grabbed at his hips, pausing when Mac stirred and whined in his sleep; he’d forgotten about the scratches. Softly, this time, he pushed at them until Mac was turned onto his side, quickly lying behind him to tug him close; it was intimate in a way no other guy would dare to show Mac.

The red flickering light from Dennis's camera shone from above them, and he'd probably regret this in the morning. But right now, that jealousy-fueled possessiveness felt too good to deny, so he kept his grip as tight as he could while he fell asleep behind Mac. Four stars didn't sound justified anymore; Mac could be a rare five, it's not like he ever went through Dennis's tapes anymore.

Notes:

I'm being the change I want to see in the world. Waiter, waiter, more Mac being a raging filthy slut, please! This was so self-indulgent, but gotta put this out there for the fellow freaks in the world, hope you freaks enjoyed this. (author is open to hearing about dead batteries or whatever)
