An abnormal submission video depicting a twisted relationship in which a real mother and daughter, both masochistic slaves, greedily pleasure each other under their master's commands. This footage compiles submissions sent to the SM magazine Maniac Club, revealing complex human relationships intertwined with sexual dependency. The man, a cousin of the mother, has been training both the mother, Mayumi, and her daughter, Akiho. According to him, he didn't initially consider this case special, but after inviting fellow sadists for mutual exchange, the mother-daughter dynamic was regarded as rare, prompting him to document it. The backstory reveals that the mother's biological uncle once inflicted excessive corporal punishment on her. Now, the man treats the mother and daughter as his complete property, recounting this history. He also claims the daughter developed an interest in BDSM naturally, without instruction, and that her fantasies became reality thanks to his guidance. The recording captures his enjoyment of perverted domination as he takes the mother-daughter pair to a seaside villa. [Recorded acts] Include vibrator insertion, beachside walking, daughter observing mother's vaginal speculum examination, mother-daughter blowjob cumshot competition, gangbang rape of the daughter in front of the restrained mother, double-headed dildo penetration linking mother and daughter, and bit-gag dildo cowgirl masturbation, among numerous extreme BDSM scenes.
