My wife does this to me sometimes. When she does, she teases me to the breaking point, over and over, until I'm squirming on the bed, begging her relieve me; but, she won't! She'll stop at that point, and tell me that she'll do it "later." I go along with that because I know she will, eventually. But not for three or four days in a row. She let's me masturbate during that time, but not come. That's HER perogative, she says. She doesn't actually care,but that's the game she plays with me. I love it, too!
She knows whats good... that should be an educational video for every woman!!!
