I have always enjoyed watching a man tease his cock in front of me. There is something powerful about sitting in a chair dressed in my heels and hose. Telling a man that he needs to stroke his cock slowly while I enjoy watching his face change shape. Bringing my man right up to the edge of orgasm only to tell him to move his attention to his testicles. The struggle as he wants to keep going knowing that will only make me upset. He wants to keep me happy so he makes the decision to do what I ask of him.
It is not just about me though I also like to watch a woman tease herself. With a woman, it is easier to control her orgasm unless she is like me. I have learned how to let my anticipation build inside so I can explode in orgasm when I desire. You can tell how much a person masturbates by how well they can control their own masturbation.
The playful side of masturbation is what I enjoy. I want to tease and deny until my playmate is begging to be allowed to explode all over. If they are a good boy or girl then I will probably allow that to happen. There have been times when I wanted to let someone orgasm but life would get in the way so they were left needing but unable to be satisfied. Sometimes I have to admit this can be a lot of fun in itself.
