God, I think I’ve written these guys doing just about every kink under the sun. OH! I know…
"Omegaverse…" Phil reads from the tablet in his hands, and Clint freezes. Phil must have picked up his tablet by mistake. He can’t just dive across the living room and grab the thing, that’d make it too obvious, so he just hums noncommittally, as if he didn’t hear.
"What is this?" Phil says, clearly still reading. "There’s tabs and tabs of this stuff…"
"Oh, that? Uh, just. Some dumb stuff I was looking at." Clint shakes his head and pulls a face, like he’d just been looking something up and hadn’t closed the tabs. No big deal.
Phil looks at him, guilelessly curious. “Is this fanfiction?”
Clint looks away guiltily. “Kinda.”
Phil swipes at the tablet and raises his eyebrows as he reads whatever it was Clint had been reading last time he’d gone down that particular online rabbit hole.
"Are these about us!?"
Clint groans, grabbing a pillow to cover his rapidly reddening face. “Yes,” he says from behind it.
There’s a silence as Phil undoubtedly reads more, sees just how weird Clint is. He has a few dozen bookmarks of stories that are much the same - himself written as this needy ‘Omega’ who goes into ‘heat’ at the most inopportune moments and Phil as his trusty ‘Alpha’, destined to be ‘bonded’ to him forever more. Knowing Phil, if he reads much, he’ll start asking about knotting and self lubricating assholes. Time to man up.
"Do you think I’m the weirdest person ever?" Clint asks from behind the pillow.
When he pulls it away from his face it’s to find that Phil’s put the tablet down and is smiling at him in amusement. “No, and I’m sorry I picked up your tablet by accident. Do you want to talk about it?”
"Not really. Well. Maybe another time? When we’re in bed. Maybe when I’ve drunk a bunch, or you’re almost asleep."
"I have some reading to do."
They talk eventually, after Phil’s managed to read just about every fic he can get his hands on. He nerds out over the fact that people write stories about him, when he used to write stories about Captain America (and Clint rolls his eyes so hard at that because of course). He doesn’t offer to do anything too weird, though he does jokingly show Clint an honest to god knotting dildo on the internet one evening. Clint explains that it’s not that he likes the idea of that whole business (women getting periods seems bad enough, this whole heat business sounds like a nightmare) but he likes the thought of Phil being that important, more than just a choice but a destiny. He rolls his eyes at himself at that, because when did he become such a damn sap?
