These two step sisters hold a grudge against their step brother, and when they find themselves alone with him, they seize the chance to exert their dominance. They march into his bedroom, forcibly undress him, and bind him with tape, leaving him helpless. With him completely immobilized, they lay him on the floor and insert a funnel into his mouth. One sister then urinates into the funnel, forcing him to drink every last drop of her piss. Once she finishes, the other sister follows suit, adding to his humiliation.
