Minako Komukai makes a surprise AVOP appearance in the Spence Breast Development Clinic series. Refusing to believe that the Spence glands are the G-spots of her breasts, she undergoes intensive development by a specialist and experiences her first breast orgasm. The pleasure leaves her rolling her eyes and losing bladder control, followed by nipple-teasing sex, toy stimulation and titjobs that press the cock against her most sensitive breast tissue.
