Norika, a demure Japanese OL, is the unsuspecting star of Muryo's hidden-camera fetish. Today, her menstrual cramps bring her to the 'doctor,' giving him the chance to 'investigate' her beautiful, milky tits. He manipulates her soft flesh, his fingers pressing into her sensitive nipples, as he asks about her symptoms. The camera, hidden in the room, records every intimate detail, from Norika's modest blushes to the doctor's growing erection, visible through his tight pants.
