I was at a party not long ago, and there was a group of girls talking about that very instrument....they were all raving about its abilities and how ergonomically correct it was...its a hit supposedly...
I had a toy once...i forget what its name was....but.... it was white rubbery something or other.... had 2 silver bullet vibrators on each end and a huge hole in the middle for the penis. At one end it had a clit stimulator too. I never used it. It kind of creeped me out. Paid 50 bucks for it too.
