Large-breasted M-type woman tightly binds her son, a music university graduate returning from abroad, in a secret room. (Lotus Water Bell BBTU-087)

A pianist, a graduate of a music academy and a returned overseas student, met a stunningly beautiful woman with enormous breasts online. The woman, named Ren Shuiling, claimed to have a masochistic fetish and volunteered to be bound out of curiosity. A bondage game ensued in a secluded room in Tokyo. Ling shyly said things like, "My breasts can feel it," and "I want to be choked." First, she was stimulated by her own shame, kneading her breasts and being ordered to open her vagina—a shameful yet erotic masturbation posture, a manifestation of her masochistic fetish. Her large breasts were tightly bound, ropes were wrapped around them, further arousing her desire, and she was constantly played with. The lustful Ling begged for a penis, diligently serving it while bound. She even cried and moaned in response to the torment of deep throating. Then, during intense throat sex, the ropes played a melody. Tied to the bed, her breasts were stepped on, lubricated, an electric massager was fixed to her vagina, and a wooden stick was used to strike her hot and painful masochistic breasts, leading to a frenzied orgasm. Bound by shells, thighs bound with ropes, nipples played with, pleasure lashed with a leather whip. A huge penis inserted into a bell filled with love juice, pounded on huge breasts, deep inside the vagina with a fleshy rod for thorough stimulation, creating a magnificent performance of pleasure and harmony.
