I have found this... thing , in Ursula's blog comment.
Click here to see it. I will not post the image directly because of what it is.
It is a dildo on a harness strap on the chest... The sight of it boggle my mind quite thoroughly and make me exclaim, in my head, how did the person who make this came up with this idea...
I suppose there must be market for it, after all, it still being sold.
