Yurika Aoi is a good woman but she's straightforward and has a strong personality. She's been married for years with a husband who's always on business trips, so they haven't had sex in years! During summer vacation, her son, who was retiring from his club activities and staying home more often, started to notice his mother's body and appearance more and more, eventually masturbating with her panties hiddenly! The mother noticed this and started to feel concerned about her son's erection. One night, the son couldn't hold back anymore and took the mother to his room and pushed her onto the bed! The mother's body naturally excited because it was a long time since she felt that way! The physical compatibility between the mother and son, who crossed the forbidden line, was surprisingly excellent! Even though they promised it would be just once, of course, they couldn't stop and fucked a lot! They were consumed by their uncontrollable libido and creampied anywhere and anytime in the house multiple times!
