Unbeknownst to their parents, two sisters harbor a dark desire: to degrade and humiliate a submissive male by urinating, defecating, or vomiting on him. Currently, they have found a willing participant, and they are determined to satiate their perverse cravings. After undressing him and inscribing obscene words on his skin, they command him to prostrate himself on the ground and open his mouth. The sisters take turns squatting above him, relieving themselves onto his face, and ordering him to devour the filth immediately.
