Mami Nagase, known for her high sensitivity, takes on the challenge of enduring up to her absolute limit. In the morning makeup room, she suddenly grabs a vibrator and begins masturbating, only to have the director snatch it away right before she climaxes. An enraged Mami is furious. During sex with a male actor, she's tormented with sex toys and forced to suppress squirting, but a mishap occurs when the man cums just before she reaches orgasm. Pushed to her breaking point, Mami secretly attempts to masturbate again in the makeup room, only to be denied once more. Finally, in the last sex scene, her pent-up desire explodes. The film captures Mami torn between restraint and raw eroticism.
