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.
