Voluptuous mature beauty Maki Koizumi plays a widowed mother-in-law who seduces her son-in-law. After accidentally catching him masturbating, her long-dormant desire flares up. She makes her move while her daughter is away, and his hesitation soon gives way to lust. On the dining table she begs him to make a baby with her and cum inside. She gives him a handjob and blowjob in the shower, wraps his cock between her huge tits, and takes a standing-doggy creampie. Back in bed, she begs for even more cum and repeatedly climaxes while hungrily taking the younger man.
