Akira is drawn to his friend's beautiful mother, Reiko, visiting her almost daily just to see her. He slips sleeping pills into her son's drink to make him drowsy, lures Reiko out, and forcefully rapes her. Initially resisting, Reiko gradually succumbs to the pleasure, eventually obeying Akira according to her own desires. She is intensely dominated—deepthroating while her son studies nearby—then things spiral out of control as Akira's friends join in. Repeatedly violated by young, rough cocks, Reiko writhes endlessly in pleasure.
