Summary
Prompt: outdoor sex
So he took him where he had no excuse, where no one could hear his screams and cries of sheer fucking ecstasy. Mac had arranged this whole trip with one hope in mind. He wanted to fuck Dennis Reynolds.
As Mac deemed them far enough, he tossed his pack against the ground and turned to face the object of his desire, the prey beneath his teeth. Eyes darkening as his gaze caught hold of Dennis, jaw tightening with the slow realization, the implications settling against the base of his skull. Swallowing down hard on his bile and his pride, he straightened his shoulders, feet turning at the heel to run.

Summary
'It doesn’t mean anything when they find themselves entwined like this; Dennis always makes sure to make it clear. It’s just easier this way. They don’t have to put any effort into seducing another person like this. It’s simpler, more accessible, and uncomplicated.'
Or in other words: Mac and Dennis 'pal-ing around platonically in the bedroom' or however they worded it.

Summary
Dennis breathes, haggard and pointed. Mac can see the inhibition gnawing at him, chewing him up, disintegrating him and waiting to spit him out. He won't be able to go to sleep and live through tomorrow as though this never happened. No, the marks and bruises will remain as a loving reminder that Mac took care of him, that Mac adores him enough to do this.
Mac will deliver when he's asked to, and he will do it well.
or, mac ties up dennis.

cut through red tape, shine like glass by aesthetichomo

Summary
“Baby boy,” Dennis coos, releasing Mac's hair in exchange for his chin, holding it between his thumb and index finger. “Pathetic little thing.”
Mac's eyes flutter shut and he whines again, and Dennis takes a moment to appreciate the dark navy stain on the front of his light blue boxers. He wonders how long Mac's been hard, let alone hard enough to be leaking like he is. It is pathetic, truly, how Dennis can tie him up like a dog and Mac will still lick his hand and wag his tail to say thank you.
or, dennis has a new hobby, and mac gets wrapped up in it.

saving all my summers for you by fatmacsbarbie

Summary
“Single room?”
The stranger- Mac, shrugs again, his eyes strangely fixated on Dennis’ name tag, raking slowly up in his chest, his throat, finally meeting his eyes once more.
“Sure,” he smiles at him, “Unless you have a better idea, sweetheart?”
Or, after getting expelled from college, Dennis and Dee are forced to work at Frank's vacation resort for the summer. As if that wasn't punishment enough, Dennis also has to deal with a handsome stranger with terrible flirting skills. Not that he's attracted to him, or anything.

Summary
"When have we ever palled around in my bedroom - or any bedroom for that matter?" Dennis threw his arms in the air.
"Oh, actually, I have an extensive list pertaining to that very topic in my notes app - wait, lemme find it," Mac said and scrolled through his phone, oblivious to the extreme eye roll Dennis produced in response. Mac began reading out loud, his voice clear and formal - like he was presenting a project in high school in front of the class:
"Top 10 MacDennis bed-sharing events - in no particular order-"
...
Just a vampire slayer and his old vampire lover palling around in the bedroom. Dennis just needs some convincing first.

Summary
“Do bodybuilders have soft guts like this? Where’s your six pack, Mac?” Dennis questioned.
“It’s—I don’t have one. But-”
“But nothing, if you were lean there’d be a six pack here, instead there's fat pushing against my face.” At the end of his sentence, Dennis leaned closer, pressing his face up against Mac’s stomach. It was warm, fuzzy, so inviting in a way it shouldn’t be; Dennis was supposed to hate this.
Mac and Dennis fight again, also Mac is fat.

Summary
Prompt - I’ve been dreaming up a fic where Dennis can’t help but act out at the focus group dinners but knows he’s gonna get in trouble with Mac once everyone leaves. That probably makes it even better for him? Maybe he’s acting out because he wants it?? Writer’s choice on where to take it. Slutty and smutty as you want (the more the merrier)

Summary
“You look beautiful.” Mac sounded breathless, and it was partly from the physical activity, but also from the sheer beauty lying beneath him. Those angry eyes softened at the compliment. He was so palatable like this, submissive in a way that allowed Mac to fully take in how lucky he was to have Dennis. Usually, he can’t appreciate him as much through the constant insults and abuse.
More tears escaped Dennis’s eyes, staining the nice sheets black as they dripped off the side of his face. “I–you–fuck you.”
Upon request, Mac breaks all his moral codes to give in to Dennis's wants. In the end, they both have always needed something to hide behind, an excuse to act out on what they both wanted.
