Summary
Mac and Charlie have always been by each other's side, but ever since Dennis left; they’ve truly been stuck by each other's side (and Mac has been working out) a lot more.
It’s just another regular movie night, that is until tension rises more and more between the two; impulsions take over.
Movie night suddenly becomes less about the movie and more about the time with the one you love watching with you; it can be hard to keep your eyes on the screen when everything you desire is in your arms. Some may like it, some may fear it; but change is inevitable. Sometimes it’s quicker than the mind can process… especially when you’re having so much fun.

Summary
“Can’t.” Mac mumbled. “Charlie doesn’t– doesn’t want me anymore because I’m a girl.”
“What?” The annoyance in Dennis’s tone faltered the slightest bit, but he still sighed tiredly. “Mac, how much have you had to drink?”

Charlie Goes Rogue - Starring: Dr. Nut and Poor Judgment by im_not_proud_im_just_horny
Fandoms: It's Always Sunny in Philadelphia

Summary
Charlie Kelly isn’t exactly renowned for making intelligent decisions, much less for making such decisions on his own. This principle will be demonstrated tonight, as he attempts the already Mythbuster-tested Coke-and-Mentos trick – in his stomach. Dennis Reynolds isn't exactly renowned for being the most considerate sexual partner, much less so when he's dealing with Mac and Charlie. This principle will also be demonstrated tonight.
Or - Dennis Reynolds forcibly understands the power of the soft dom by making an ass out of himself.

Summary
Prompt: creampies
He moaned around their cocks, his body already having forgotten its last lesson; though, how could he ever really forget when they fucked him like this? His body bowing to their every wanton whim, his cunt certainly remembered this sensation.
His cunt had craved this, each and every night that he'd spent with the waitress. He'd found no satisfaction in the toy between his legs, no satiation in the flush press of silicone against the flesh. She'd taken him with such little enthusiasm, her little grunts and groans falling pale in comparison to this. In cramped back offices, fucked against the dirty carpet, it didn't matter when or where; Charlie had been fucking aching for this.

Summary
Prompt: free use
All it took was a casual command, to take him wherever they pleased, to warm their cocks inside his soft and pliant body. They'd fucked him behind the bar, in the back office, on the couch that he shared with Frank when they settled for the night. They would shame his body for its eager response, the wetness gushing to meet their fingers and tongues, and praise him for it in the same breath. They'd take him whenever they decided he was worth fucking.
It was how he had ended up here, on his hands and knees against the dirty carpet, cunt bared and mouth hanging open.

Summary
Charlie quickly crouched low behind a blackberry bush that was within the parameters they had set in advance. He could just barely see their orange cone about five metres away. His breath was harsher than he wanted, his legs burning from running. He took a few moments to deepen his breathing, hoping it would quieten.
Or, Charlie is being chased through the woods by his Hunter.

Summary
Prompt: threesome
His frame was smaller than theirs, lean and wiry between their sweat-soaked bodies. He had always been a good bit shorter than everyone but Frank, always had curves in places that other boys didn't, but Dennis and Mac never made him feel weird about it. There would always be things that he'd be insecure about, always be things that didn't look right, weren't masculine enough. But between the palms of his friends, his almost-lovers, he found no shame, no humiliation.
Not yet, anyway.

Dennis Reynolds and Vicarious Living by im_not_proud_im_just_horny
Fandoms: It's Always Sunny in Philadelphia
04 Sep 2025
Tags
Summary
Truthfully, Dennis is all too fucking happy to see Charlie plump up. It’s a kind of vicarious living. Watching Charlie get bigger and bigger makes him feel smaller and smaller, which, as it turns out, is a sickening power. Something about seeing his little hamster cheeks puff out with food goes straight to Dennis’ cock- and Charlie’s so eager to do it, too. Charlie loves food, and Mac loves Charlie, and Dennis loves watching Charlie ruin himself. It’s a simple system, really.
Or - Dennis plays hardball, Mac plays softball, and Charlie couldn't give less of a shit what game they're playing; he just wants to eat.

delusions of a walking corpse by donthuffglue

Summary
"I know you think you're dead, and this might not help at all, but do you want to have violent, desperate sex? Does death rid us of our ability to be intimate, or can I still visit your bones over and over again? Will it help to know that your skin feels warm against lips and even if your limbs won't work, you're still my best friend? I don't care if death is meant to do us part. Love is cold, cold like a corpse, and I want to hold yours. I want to make yours. I wish you'd hold mine. I wish we were capable of touching without the hardened steel and the scent of decay between us."

Summary
Then, he hears it. A shift in the night, leaves rustling, a branch breaking. All sounds that have become entirely familiar, ones that paint him a perfect picture in his head: Charlie, late on his schedule, attempting to scramble up the tree just outside of Dennis' window as quickly as possible.
Suppressing a smile, Dennis opens his curtains. Let the fun begin.

An alternate universe, in which Charlie stalks Dennis rather than The Waitress.

Summary
“Wait!!” Charlie managed to cry out as Dennis maneuvered him to lay in the center of the bed rather than on the edge. “Wait, guys—guys,” Charlie stumbled over his words, pressing his thighs together to keep the two boys away as he spoke.
Mac and Dennis froze for just a moment, ready to listen to what Charlie had to say before they devoured him whole.
“I-I don’t want to do this with you guys. We’re friends, I-I don’t want to make things weird,” Charlie stammered, the sweat on his forehead making his hair stick to his face, dampened from all the moisture.
“It’s not gonna be weird, Charlie,” Dennis had a menacing look in his eye as he crawled atop Charlie. The omega felt his heart pounding in his chest. Normally, he trusted Dennis. Right now? He wanted to get as far away from the man as possible.

Aka: Dennis and Mac find Charlie in heat. What else are they supposed to do?
