We're going to play a game. I get to decide how many strokes you get and how long you get to stroke for. When I say stop or you run out of allotted strokes, you stop. Teasing you with my body and controlling your strokes over and over. Until I'm ready for your last 20 strokes. If you cum early, you ruin it. If you can't cum in the number I strokes I allow, you're blue-balled. My game, my rules.
