three headed dragon

The act of oral sex between a man and two women in which one woman lays on her stomach while blowing the man while he is on his back, and he simultaneously eats out a woman who is on her knees leaning forward. It creates an up down shape like the body of a dragon. Hence the name.

Last night I met these two chicks. We went back to my place and made a three headed dragon.
