Close friends Emi and Ruru head to their master's mansion with smiles on their faces. The training begins as they are made to greet him with naked prostration, their heads crushed under his feet. From there, it escalates without pause—nipple clamps, whipping, inverted deep throat and throat destruction, anal play, drinking urine, aphrodisiacs, forced lesbian acts, and watching others have sex. The two cry out in ecstasy, tears and drool mixing as they reach their peak as slaves in a final, intense double penetration scene.
