I think he hopes for spontaneous and risky locations/situations if trevor is involved, but complains the next day when his ass, back, and knees hurt. If he had it his way he'd be clapped lying back on a bed without lifting a finger, but he definitely secretly likes when trevor folds him in half on his is back and makes it hard to breathe. or doggy and pushes his face so hard into the mattress/countertop he has similar problems. But all together?? I think any position is his favorite if theres a risk of being caught. Like if theyre currently running from the law and trevor parks haphazardly into an alleyway and forces Michael into the backseat for a quicky while they can hear the cop radio chatter?? Hes gonna bitch and moan but its gonna be the best railing of his life.

Of them together? Hmmm.. i think Michael likes to buy "ugly" clothes for trevor just because they remind him of him. (Sometimes ugly means genuinely hideous, other times its somthing like the pussycat shirt where Michael's kinda /hoping/ he'll wear it).
I also love the idea of M hiring Trevor to do his "lifestyle guru" thing (its canon as of an online update i promise im not insane) on set to scare the actors into staying in-line.
I also think if theyre in public together theyll openly mock and bully people around them. Like singling out one person to just make snide little comments to/about until it becomes genuine harassment lmao

Aaah, thank you so much?!! And oh man, thats an answer that can go so many different ways. I think Trevor would prefer anything where he could see Michael's face, but he's not too picky because sex is sex. He'd probably also go for the more wild positions in spur of the moment situations like butterchurner, or anything where he can bend Michael into a pretzel.
Michael -depending on how repressed hes feeling- would probably prefer anything where they cant look at each other lmao. Once he gets over himself, I think itd be a lot of normal stuff like missionary, or being riden/riding while sitting down. But again, sex is sex. He'd probably never admit it, but he likes the spontaneous weird sex positions Trevor gets him caught in.
Id love to hear your input and thoughts though, there's so many ways it could go with these assholes lmao

Oh man. You cant ask me that, theres too big of a list and im gonna forget most of em. Uhhh... degradation, praise, leather, fighting, choking, piss, breathplay, somno, battling for dominance, painplay, prostate milking, ball torture (light, michael is a coward), trevor likes ruining michaels expensive clothes and in return michael likes seeing trevor in suits, sweat, musk, armpits (those are all givens but), knifeplay (Trevor mostly. M was more into it when they were younger), gunplay, cumplay, roleplay (dirty cop, "revenge", young actor and sleazy movie producer, theres a lot that i think theyd both get a kick out of) exhibitionism, adipophilia on Trevors side, bondage, pet play but only kinda, cross dressing, uh. Theres more, im sure. But its like 8am so
