"Yesterday, when I got scolded and slapped... I couldn't stop thinking about it..." Giving in to her extreme masochistic urges, student Kishi Nagomi shows up at his place uninvited. Trembling with nervous anticipation, she pleads to be disciplined. Starting with choking, he then gives her a finger deep throat, watching her drool as she wears a blissful expression. Turned on intensely by her reaction, he takes her to bed and begins brutal deep throating. He gropes her voluptuous, curvy body, choking her while ruthlessly dominating her. The days of after-school BDSM lessons that begin today will shake her mind even further.
