Ayako is a single mother who has raised two sons. However, while the younger brother has grown up to be popular, the older brother Ichiro has become gloomy and unpopular with the opposite sex.

Although it is an unforgivable act, Ayako, who has been away from sex for a long time, climaxes many times with her son's hard cock. Before she knows it, she has become an obedient masturbation pet, wetting her crotch and begging for penetration... #ChiefP
