This is a variation of the Danny Glover and the Donkey Punch. The man must get his member good and dirty with feces while anally plugging his partner. He must pull out and whip her ass with his shit covered cock. This makes her ass
black like a black horse and you have now
whipped her like a race horse jockey would. After her buttocks are good and
black the man re-inserts his member into anus. When he is close to climax he pulls the ole Donkey Punch by punching her in the back of the head.
