A Penis-Vagina-Cock (or P.V.C. for short) is a mythical creature that is half penis, half vagina and all rooster. This beast is the result of an unfortunatecombination of man, woman, and cock. Closely related to the Basilisk, the Penis-Vagina-Cock has been rumored to hunt down and rape these creatures.
Nathaniel: Holy crap Bob! Is that a cock with a penis and a vagina?!
Bob: Yep. That's just one of those Penis-Vagina-Cocks I was telling you about. I've been breeding them in my spare time. Sexy creatures, aren't they?
