IESM-035 Hamasaki Rio: Oni’s Grinding – 104 Minutes of Squirt Performance, Planned by Bou Baku

Rio, a married woman blessed with stunning large breasts, decided to undergo extreme discipline for the sake of supporting her husband's work as an S&M magazine editor. However, the intense bondage techniques by the legendary S&M artist Oni Yakuin pushed her beyond her limits. Bound tightly in the garden, she was tormented with electric shocks and rope bindings that turned her smooth, pale skin bright red. Helplessly restrained, she felt a throbbing erection forced deep inside her, climaxing violently as she squirted uncontrollably, surrendering her body completely to brutal, relentless training.
