While performing intercourse from the rear, be it anal or vaginal, the male will hock a snot ball up in his throat quietly. As he approaches orgasm he must pull out, secondly letting the spit ball land on the females back, making her think that he just got off. Then as she turns around the male must quickly jack off and spooge in her face to complete the maneuver correctly.
