With a female friend years ago. She explained up front we would only masturbate ourselves but I could watch her and she wanted to watch me.
I was a little surprised when she went first. When I was going to start she suggested I sit on a suction cup dildo on her tub. I was shocked but really turned on so I gave in.
I ended up riding a dildo and jerking off while she watched and I found out later that she had a hidden video cam.
