I was interested in Roger's post about going into public loos with his girlfriend and watching her masturbate. I was particularly interested that she told him she often did it in there as I have been doing it on the loo all my life, ever since I started when I was at school.
My reason for doing this is that I discovered early on that if I masturbate with a full bladder the feeling is intensified. What I do is wait until I really need to pee, then go into the loo, sit down with my knickers down and legs spread wide and rub my clitoris hard and fast. As I cum, which happens very quickly, I invariably have to let go, and I pee as I am having an orgasm. For me this really adds to the pleasure, and the only drawback is that my orgasms are so intense that I have great difficulty keeping quiet, which can be awkward when there are other women in nearby cubicles.
Like Roger's girlfriend I keep my ears open when I am in a public loo, and from time to time I overhear the unmistakeable sounds of someone making herself cum a few feet away from me, so I know for a fact I am not the only one getting a lot of pleasure from a trip to the ladies!
