When you are nailing your girl in the ass, pull out and spit on her back/ass (making her think you finished). Then when she turns around, blast her in the face with your actual load, completely surprising her like a fireman with his hose.

Get the Surprise Firemanmug. When you're boning your woman/man doggy style and right before you cum you pull out, pinch off and spit on her/his back. When she/he turns around spray your load in her/his face.
