We made a mold of my penis, then filled it with "liquid skin" and inserted a vibrator. It came out a very good replica, except half an inch short, being as that we poured all the stuff in and it only came that high in the mold.
She was very excited. She sucked my real cock while I fucked her with it, and she had the most explosive orgasm I've ever witnessed her having. That's what Christmas is all about, I guess. If one of us gets a digital camera under the tree, I'll post some pictures of the original and the duplicate, for comparison.
