A sand vagina is much like a regular vagina but instead the flesh is replaced by sand, do not head south of the clitoris on a sand vagina, or you'll find yourself at the pee hole and thats just not fun. If you somehow get bored with the sand vigina, you can keep moving south, there you will find the corn hole, just remember, what goes in, must come out
Hey Look! over there, on the bay!
Its a Sand Vagina thats wants to play!
So jump in friend you good ol' pal!
Or everyone will call you a homosexual!
