Karina Nishida is a masochist who loves BDSM, preferring ropes over sex. Among the many works she has filmed, this training project holds special significance as her final collaboration with the production team. Born from the crew's desire to "shoot with her one more time," the session begins with friendly conversation before tightening dramatically when bondage master Tetsushin Doyama slaps her. Instantly, Karina's masochistic switch flips on. She screams, "Harder!!", "More painful!!", "Stricter!!", fully embodying true masochism.
