I had a friend Sherry S. from Loveland, CO. that would do this for me so I could watch. We'd fuck a couple of times then I'd try to talk her into doing this for me. I bought her a penis shaped vibrator like this. She's never had one, didn't know what to do.. Once I showed her, she enjoyed it. When she would, It was a great turn on for us both and we'd fuck some more.
