A horrible multi-stage sexual act. In the first stage, milk is procured from a lactating woman. Then, the woman is anally fisted until she has attained anal width sufficient to receive the insertion of her own breast milk. Then, she is ass fucked until the milk turns to butter. The butter is then extracted and served over toast (serves up to twelve. For double servings, use two fists ((or two women))
