There are few positions in which someone can be more vulnerable than when they are getting fucked on their back.
It can help to remind your faggot, from time to time, that this vulnerability isn’t “hypothetical.” He chooses — actually fucking CHOOSES — to be put into a position where you can do anything to him.
Your hands wrapp tightly around his neck, your open palm violently slapping his face, or even — if you are feeling particularly cruel — your fist connecting directly with his jaw — all serve to send the point home.
Your faggot should know exactly what he’s asked for. Not some fiction, but a very real vulnerability that allows a Real Man like you to do ANYTHING and EVERYTHING you want to him just to get off and for no other reason.
