Showing the vaginal area.
I saw these chicks flashing trucks on the highway, they had spread beavers!
When a girl spreads her cunt (labia, flaps, vulva) completely apart with her fingers to show ALL of her vagina. This is commonly done in Penthouse magazine.
1. There is plenty of spread beaver in Penthouse.
2. The stripper spread her cunt apart and the crowd cheered and taunted her spread beaver.
3. The whore loves to show her spread beaver.
