When a precocious boy moves into the neighborhood, the peaceful days of mother and son are ruined. The precocious boy sets his sights on the beautiful mother Asakura, pretends to be her son's friend, and tricks the mother into becoming his sex toy. When her son isn't looking, he gives her a blowjob, rapes her in the middle of the night and ejaculates a huge amount of semen inside her. To top it off, he even takes his son's dick. The mother, who was underestimating him as a child, falls into the trap of the outrageously devilish boys and becomes a lewd, slutty mother.
