I met a beautiful, super-endowed pianist who is a returning foreign student (likely from a music conservatory) through SNS. Her name is Rin Rensui, and she claims to have an M (masochistic) personality and volunteered to be bound out of curiosity. We immediately went to a private room in Tokyo to engage in bondage play. Rin, while shy, expressed a desire to feel her large breasts being bound and her neck being choked. We started by teasing her shame, encouraging her to touch her own breasts and spread her legs. Despite her shyness, her self-pleasuring session, fueled by shame and desire, was a perfect example of a true M personality. Her sensitive vagina was then bound with her beautiful large breasts, further intensifying her arousal. She became even more aroused by the ropes engulfing her breasts, begging for a penis. Despite being restricted, she diligently served the penis, her desire overwhelming her. She endured intense throat stimulation, crying and gasping in response. Her bound breasts created a rhythmic motion during intense throat thrusts, as if playing a melody on the ropes. Rin was then laid on the bed, her breasts stomped on and rubbed with lotion. A dildo was fixed to her vagina, and a red wax candle was dripped onto her breasts, causing further arousal and pain. She reached orgasm from the intense sensations, whipped with a rose whip, feeling the heat and pain, her M nature taking over. She continued to indulge in pleasure through turtle binding, vaginal rope play, nipple clamps, and spanking. A large penis was then inserted into her, overflowing with lubrication. Her breasts were pounded, and her vagina was deeply and thoroughly penetrated, creating a symphony of intense pleasure. Please note that the content may vary depending on the distribution method.
