BS-47 Kawakami Tsuvaki: Masturbation Hell – 6 Ejaculations in 2 Hours, M Men Squirting Under Dominant Woman’s Control, Planning MAXING

A masturbation-focused adult video featuring instructor Kawakami Tsuvaki pushing an M man to his limits. It starts with an explanation of 48 different masturbation positions, followed by hands-on practice. Even those who climax quickly will be trained here—this is the true ground zero of masturbation mastery. Through relentless handjob techniques, continuous stimulation leads to repeated ejaculation. After intense forced orgasms, the man is driven into a state of mental exhaustion, then subjected to extreme 'milking' to forcefully extract every drop of semen. This is followed by powerful ejaculation from prostate stimulation, and yet again, more forced climax. One man is made to ejaculate six times—this is ultimate masturbation torture. Handjobs are a form of SM!
