How to Give Another Devastating Handjob
Say, “Together, we’re going to discover exactly where your edge is. And Honey, don’t get any bright ideas about letting me go beyond the point of no return. If you cum before I’m ready, I’m going to put you through some good, old-fashioned post-orgasm torture. You know what that is, don’t you? That’s when I don’t stop stroking your cock just because you’ve cum. A man’s penis gets very sensitive right after an orgasm, doesn’t it? And the continued stimulation is almost too much for him to bear. But you’ll have to put up with it, won’t you, because you’ll be helpless to stop me. You’re at my mercy! So you had better let me know when you’re getting close."
(Having made this threat, you need to be ready to follow through if he does cum without permission. The post-orgasm torture (POT) will give him an exquisite sensory overload, and he will thrash in his bonds to try to get away from you, but POT can’t do him any permanent harm, so don’t hesitate to punish his disobedience.)
