Veteran G-cup porn star Satomi Suzuki enters the Spence Breast Development Clinic, where the so-called G-spot of her breasts is forcefully stimulated with specialized equipment. A breast-sensitivity expert gives her a first breast orgasm so intense that she climaxes into unconsciousness. Nipple-teasing sex, toy play that makes her leak urine, heightened-sensitivity titjobs and repeated full-body convulsions complete the session.
