The double virginity is something I discovered in the "Elven Maiden vs. Human Barbarian" game. basically it seems that elf maids have the normal hymen like any other girl but they also have another hymen that directly protects the cervix. The idea being that elf men aren't normally long enough to break the second virginity and so human babarians, when they rape the elf maids(even mature ones) find the deep virginity. Plus, since elf girls are smaller, the barbarian cock gets all the way past the cervix into the womb and presses against the back wall which is also attached to the diaphragm. In this way when the barbarian fucks into the little elf maid he can push against her diaphragm forcing all the air out of her lungs, in essense forcing her to breath only when he allows it. very very sexy for those of us into the rape side of things.
