a.k.a. "The Magic Bullet" - Have a girl wear a blindfold while she is giving you head. At the same time, have a friend sneak in behind her and pleasure himself behind her. Both of you let 'em rip at the same time and nail the skank with goo from both sides of her head. She will always question if there was a second shooter or it was just a magic load.
I think my boyfriend had a friend of his help him JFK me last night. But he insists on a "single bullet theory."
