Natsumi Asakura, who has done outdoor masturbation, been fondled by a beautiful senior in the library, and visited a women-only sex service, visits the editorial department saying she wants to know more about the SM world. She says she hates pain and embarrassment but will do her best if her partner wishes it. With a collar around her neck, she is ordered to obey absolutely, and the play begins. Her fresh body is thoroughly examined, and she winces with shame. She blushes at being smelled during anal torture and screams lewdly during restrained genital expansion. Then, with clothespins and whipping... she is tormented with the things she said she hated. As she endures the pain, her face becomes more beautiful with tears and drool. This work captures the budding M nature of Natsumi Asakura.
