"It gets really cold in San Francisco," Sandra told us. "That's why I take three or four hot showers every day in the winter. Well, that's not the only reason. It's where I masturbate. I've tried lying down in bed, but it's not for me. I like the feeling of water bouncing off of my skin, it's relaxing and it helps me cum. I can get off in about five minutes if I'm in the tub. I have to double that time in order to cum during sex.".
