Japanese Women's Sexual Response Survey: The Reality of Orgasms Who's the JAV actress in this video? Amateur? Name revealed!

A fetish video series for medical enthusiasts by Chart Mania titled "Chart Tsushin." This series is produced by former editor-in-chief of the medical fetish magazine "Chart Tsushin," Junji Futagi, and features experimental footage emphasizing medical perspectives. The fourth installment focuses on a study of sexual responses in Japanese women, documenting multiple orgasms in a female subject in her late thirties. A defining characteristic of this series is its deliberately clinical, detached, and at times merciless approach from a medical standpoint. As such, it contains no sexual acts that deviate from standard medical procedures, nor any sexual contact between medical staff and patients—elements commonly found in typical medical-themed adult videos. [Content] The video centers on medical observations including basic examination, chest auscultation, abdominal auscultation, abdominal palpation and inguinal lymph node examination, breast palpation, collection of nipple discharge, observation of orgasm through masturbation, observation of convulsions during orgasm, observation of orgasm via mechanical clitoral stimulation, observation of orgasm via mechanical clitoral stimulation with cervical exposure, observation of consecutive orgasms via post-orgasm clitoral and vaginal stimulation, observation of orgasm via mechanical stimulation of the clitoris, vagina, and anus, and post-orgasm measurements of nipple diameter and clitoral width.
