Younger Michael likes your hand around his throat, not really choking but enough pressure to hinder his breath. And the look of pure bliss as he sputters for air, you hold just a little tighter as he orgasms, sending him into another world of pleasure for his release, high pitched groan as best he can.
Older Michael would almost be insulted if you were so soft with him, wrap your hand around his neck, choking turns to asphyxiation if he gets his way, strangled groans as he rides out in pleasure, he wants to be seeing spots and if you're too gentle he'll pull your other hand to place it on his neck and make you squeeze.
