Momomi Sawajiri witnessed her parents' BDSM play during high school, an experience so shocking it remained etched in her memory. Even after entering the adult video industry, the recollection never faded. Now, she finally steps into a full-scale BDSM training session. From outdoor rock-holding torture and triangular wooden horse punishment, to whip flogging, single-leg bondage vibrator sessions, tightly bound suspension with candle wax and whipping, and tightly restrained milk enema injections—each scene weaves an erotic pleasure that gradually consumes Momomi, drawing her deeper into submission until she reaches climax. Every moment pulls her further into the abyss.
