Slave is extra horny after a full week in chastity and being denied. And today I want to see how much he can handle. That is my entertainment after all- Just getting him super close, as often as I can.. Helplessly bound and exposed- I shut him up with my ass on his face, and start teasing him in some amazing soft latex medical gloves..  I dictate when he's allowed to cum, but it's not time yet.. I edge him over and over again and frustrate him.. He wants to cum so bad I psych him out with two countdowns. The first countdown I don't squeeze his cock very hard at all, and the smooth soft gloves make it impossible to cum as I get closer to zero.. He think's he's missed his chance.. Then he gets a second, really slow countdown- which leads to one of the longest lasting ruins I've ever done.
