I set the shaft rotating, and pushed it in and out, as near as I could to her like I would penetrate her naturally. After a few minutes I switched the clit buzzer on slow. After ten minutes she began to writhe on the bed. And very soon had a massive orgasm, frantically kissing me like when we were first married. As it subsided, I reversed the rotation (and repeated this every five seconds or so). She quickly had another massive one, and was in tears of ecstasy.
