46-year-old Minami Yamabuki has been sexless for three years since her husband changed jobs five years ago, when he started working overtime and going on business trips, which he had never done before. With no one to cheat on her with, Minami has been satisfying her sexual desires with masturbation, but when she found out about mature women's adult videos, she applied through a website and was cast in one. She bought some corrective underwear on a TV shopping channel and her breasts have gotten bigger, and they are so sensitive that she cums just by having her nipples sucked!
