Since the husband returns home only a few times a year, the son spends most of his time at home alone with his mother. One day, the mother catches her son masturbating in the bathroom and, overcome by the urge to pleasure him, begins giving him handjobs and blowjobs. Later, while her son is asleep, she seduces him, craving pleasure for herself as well. This fully original production features four stories starring Iku Kondo, Rika Fujishita, Shino Oishi, and Mari Kikukawa, each showcasing their unique charm in explicit incest-themed scenes filled with handjob, blowjob, and masturbation acts.
