A pair of twins, previously subjected to their stepfather’s tyranny throughout their upbringing, seize the opportunity for revenge now that they are independent adults. They visit their stepfather at his residence and quickly strip him of his clothing. One of the twins mounts his face, satisfying their long-standing desire to dominate him. She urinates into his mouth, forcing him to swallow mouthful after mouthful. Once she is unable to release anymore, her sister takes her place, first allowing him to taste her own vagina before urinating into a glass and having him drink it. She then urinates directly into his mouth, only stopping when she has nothing left to release.
