Kurea Hasumi, the queen of a lewd sensual shop, suddenly marries a pathetic, submissive older man and becomes the stepmother to his sons. She provokes the eldest son into lewd masturbation, while giving the younger son intense blowjobs, nipple torture, relentless footjobs, and intricate handjob techniques. Unfazed by her husband running away, Kurea indulges in incestuous threesome sex with the two brothers. Riding them with sensational cowgirl motions, she repeatedly brings them to the edge only to deny release, driving both brothers to scream in ecstasy as they're overwhelmed by ultimate pleasure and erupt in massive ejaculations.
