Jun Mizukawa finally enters full-scale BDSM, revealing a level of masochism that even the director praises. Rope master Tesshin Doyama puts her through serious slave training with slaps, spanking, forced deep throat, nipple torture, a rose whip, stomach punches, upside-down suspension, hot wax, and hemp-rope bondage sex. Every punishment is real, her masochistic orgasms never stop, and she squirts so violently it has to be seen to be believed. Widely regarded as one of Shisui Usuba’s finest works.
