My wife made a vibrator from a mold of my cock a few years ago. Awhile ago she admitted to using it to masturbate when I'm away a lot.

Then she told me that she passed it around to her friends one night when they were drinking at our house. All her friends played with it. It's kind of cool since it is an exact duplicate of my dick. She then told me that two of her friends borrowed it to masturbate with but won't tell me which ones. It's as close as I'm gonna get to fucking them I'm sure.
