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
