I got to know Rinka Hasumi, a pianist and returnee who graduated from a music university and has super beautiful big tits, through SNS. She revealed her masochistic tendencies and expressed her desire to experience bondage play out of curiosity. To fulfill her wish, I set up a private room in Tokyo and carried out the bondage play. Although she was shy, she uttered words like "my big tits are feeling it" and "I want my neck to be squeezed," and allowed me to fondle her big tits in a way that aroused her humiliation. She was further asked to spread her pussy wide open and, while being shy, she performed a humiliating masturbation filled with lust. Stimulated by the rope binding her big tits, and being tormented by her protruding big tits, Rinka, who was getting aroused, begged for a dick. In a state where her freedom was taken away, her desperate dick servicing was the epitome of her masochistic tendencies. She was subjected to deep throat torture, tears streaming down her face, and sobbing as she gave in to pleasure. Then, she was given intense throat pistoning while shaking her big tits, and the rope's melody was played. Rinka, who was lying on the floor still bound, had her big tits stepped on, and lotion was rubbed all over them while an electric vibrator was fixed to her pussy. Red candle wax was dripped on her, and her big tits were tormented mercilessly. She was further hit with a rose whip, and as she felt the heat and pain, she was led to a state of frenzied masochistic big-titted ecstasy. She was subjected to stockade binding and thigh rope torture, and she indulged in pleasure with nipple clamps and spanking. As she was overflowing with vaginal fluid, a huge dick was shoved into her, and while her big tits were slapped, her vaginal depths were thoroughly pounded, producing a rich amount of pleasure. It was a scene where a magnificent harmony resounded.
