By day a female college student, by night a popular hostess at a high-class Ginza club, Tsugumi struggles behind the glamorous facade—burdened by debts and pressured by wealthy clients demanding expensive gifts. To relieve the mounting stress, she reluctantly agrees to shoot a sex video, crying as she does so. Despite mentally resisting, her body betrays her as she experiences repeated vaginal orgasms. Her sensitivity becomes so intense that her pussy tightens uncontrollably. After receiving a creampie, the shy and embarrassed Tsugumi bursts into tears and rushes to shower, revealing her deeply vulnerable side.
