This live-action adaptation of Natsume Benkei’s popular incest doujin stars Yuria Yoshine as a massively busty mother torn between parental guilt and love for her adult son. In this adult mother-and-son role-play, the sexually frustrated son becomes so obsessed with her breasts that he commits an act of groping. Hoping to prevent further offenses, she decides to let him fondle her K-cup tits for release. His appetite only grows, progressing from handjobs and titjobs to raw penetration. Though she knows a mother must never cross that line, she cannot reject him and ultimately has secret creampie sex she can never reveal to her husband.
