Heh, reminds me of a book a read not too long ago which had a chapter where two girls play chess on a giant board in a big elegant room with lot's of men in suits and all that. Two men directed the girls to move the pieces they desired and they would stand on the table and pick up the pieces in their vagina's then drop them down in the correct place.
The rest of the book wasn't so great though. Lol!
My problem with erotica (assuming it is)... It seems being a bit mad is the norm!
