PRESTIGE exclusive actress Umi Yatsugake undergoes intense training in this secret recording, depicted as a pet being raised through discipline. The session begins with her on all fours, a collar around her neck connected to a chain. Disobedient pets are punished with spanking, each strike echoing with the clink of cold metal and lewd moans. When a hard cock is forced into her mouth, she swallows it with teary eyes and drool dripping down her chin. Grabbing her long, beautiful black hair, her master takes her from behind, and she grinds her hips on her own, chasing orgasm. As the relentless thrusting continues, her body surrenders completely to inescapable pleasure. A combination of restraint, foot worship, deep throat, and other forms of domination push her deeper into masochistic ecstasy. As a candidate fully accepting every act, Umi crosses new boundaries, becoming the perfect obedient pet.
