Summary
Dennis is in shock and denial when Mac has a new boyfriend (who maybe looks a bit like Ryan Reynolds). The Gang tries to help with poor results. Series wise: this is a standalone or replace 10pm with it if that's what you like. (Pretty much all of them can be read as standalone).
Series
- Part 3 of The Adventures of Mac and Dennis

Summary
Mac comes out in the brig of the cruise ship and Dennis starts to feel again. He’s not exactly sure what, but it feels suspiciously like something he’s spent decades pushing away. It’s something. And for the first time in a very long time, it might even be real.
or-
Dennis Reynolds is forced to confront his feelings, the vulnerability that comes with them, and the man who’s somehow loved him through all of it.

Where Is Your Boy Tonight? by thnksfrthemilksteak

Summary
Dennis hated Mac McDonald.
He hated him with all the fury of a crazed man.
That's why he craved the warmth of his eyes and the taste of his filthy lips and spending balmy evenings beneath him.
That's why every time the scent of coffee breezed by, every time the night was particularly bright and freckled with brilliant stars, every time he felt a rush of thorny thumps where his heart should be, he thought Mac McDonald.
That's why he couldn't have him within arm's reach.

Summary
Dennis can’t tell if Mac is trying to give him space, or if he’s making some macho attempt to prove that he doesn’t need anyone, not even Dennis. It's frankly ridiculous. Screw him for forcing Dennis to make the next move.

Summary
Prompt - I have another prompt! (no rush to get it done) I was thinking a fic where the gang is arguing about who’s the best kisser. Dennis thinks it’s him, but the others don’t believe him so he has to prove it… he ends up having to kiss Mac in front of everyone. He acts disgusted by the idea, but still does it (anything to prove he’s right) and something just clicks. He can’t stop and they get more and more into it. Where it leads and the everyone’s reactions is up to you!

Summary
They're ten feet deep into the haunted house when a giant plastic bat drops from the ceiling into their faces.
Mac startles (in a very manly fashion), but Dennis fully shrieks, and Mac feels hands wrap around his bicep. Looking to his side, Mac confirms that yeah, he’s not going crazy. Dennis Reynolds is latched onto his arm tight enough to bruise, eyes squeezed shut like he’s some helpless damsel.
Mac is— Fuck, so this is definitely turning him on.
Or: 5 times Dennis uncharacteristically clings to Mac + 1 time Mac characteristically clings to Dennis
