Beautiful MILF Yumi Kajiyama is concerned about her son's sexual development. He's around the age where he should definitely be very active when it comes to sexual activity, yet she's never found any erotic manga or porn mags when searching his room, neither has she found any porn on his computer or phone, hell she hasn't caught him masturbating even once. Since she's his mom, he never talks to her about these things and it's getting really concerning to her that he might be oppressing his sexual needs. She's been married for 18 years, and she's done a little bit of fooling around every now and then despite the fact that she and her husband have sex more than 3 times per week on a few occasions, which is an impressive number considering how long they've been married. Perhaps watching his gorgeous mom plowed hard and stimulated with toys, fingers and hard cock behind his dad's back will give this young man the desire to touch himself as he should be doing.
