If a Mistress really wants to get a slave worked up once they are tied and can not escape take a condom and put about 1 teaspoon of rubbing alcohol in it. Jack the slave until he is hard and put the condom on him. Slowly keep jacking them off until the alcohol has covered his dick completelyand keep going slow. It feels GREAT at first and then the burning begins. If the Mistress is nice she may let him cum, if not he will be burning a while. Jodie has done this to me and it works.
