You're going to be a Thirty Pump Stoker for me. You're allowed to jerk off but you're only allowed to pump your cock 30 times. And if you run out of pumps before you cum, then you don't get to cum. But don't worry, I'll help you by teasing you with my big, round, bouncy tits and my sexy curves. Make no mistake though. This is a challenge. A very hard one. Can you cum in just 30 pumps?
