You need to gain better control over your body. You've gotten stuck in such a loop of horniness, stroking, cumming. You're out of control. Controlling your cock is not solely my responsibility. Though I do delight in ruling you with a strict iron fist, you need to do your part in your behavioral training as well. Only a malleable slave is a valuable slave. You must learn not to get hard so easily, for everything. Your boner does not rule you. I do.
