From the missionary position, about to cum a man pulls out and pins the women's arms down with his knees then sprays her face with cum. Her thrashing head and pinned arms resemble a pterodactyl in flight. Her screams add to the effect.
Background: Snoop's song "step yo game up" ..at the end it was a little confusing to figure out what he was saying.
Mike convinced Jessica that it is a sex position.
Definition: When a girl is on her back with her legs spread open like a pterodactyl and the guy is fucking her with his backside facing her and as they are fucking her legs flap like a pterodactyl. It ads more force and depth to the penetration. Screeching is optional..but recommended.
