This live-action adaptation of Golden Bazooka's forbidden mother-and-son comic features adult performers in an incest role-play. Miyuki is a devoted housewife and mother living comfortably with her successful husband, but her adult son's relentless masturbation has left him at the bottom of his class. Furious, she promises to relieve him sexually if he ranks first on his next test, never expecting him to succeed. Forced to honor the deal, she begins draining his endless supply of semen every day. Then her husband leaves on a business trip, and her son gets on his knees to beg for sex. Daily service has already awakened Miyuki's own desire, leaving the big-titted, big-assed mother to face her adult son's throbbing cock.
