In a dimly lit Japanese clinic, a lecherous doctor, Muryo Ero, exploits his position to satisfy his voyeuristic urges. His hidden camera focuses on a 28-year-old OL, her ample breasts heaving as she lies on the gynecological exam table, unaware of his prying eyes. The doctor, his eyes gleaming with lust, performs an unnecessarily thorough internal examination, his gloved fingers delving deep into her warm, wet folds, as he drinks in every intimate detail.
