Introduced to a massage parlor by her older brother, the younger sister—dreaming of becoming an anime voice actress—naively accepts the treatment without suspicion. Sensitive areas are coated with oil, causing her to gasp and tremble. Drawn in by the therapist’s words, she begins masturbating as instructed. Blindfolded, she writhes under intimate stimulation, her vagina growing wet as she accepts a penis and convulses in ecstasy. Unaware that her brother has taken the therapist’s place, she continues moaning in pleasure. The incestuous scheme slowly unfolds. To fulfill the client’s request, Kurikey Takefumi takes action. The entire act, secretly recorded: the full truth of the consanguineous incest plot captured on camera.
