Big-breasted mother, Yukimi Kondou. A single-parent household with troubles regarding her beloved child. Literally, a son who can't wean off his mother's breasts. No matter what he does, the second thing he says is 'breasts.' A son in his teens groping overly ample breasts. However, she unintentionally felt pleasure. Then, she was caught masturbating. Since that incident, her son would grope her breasts from behind even while doing chores without any hesitation. "No, don't...!" Her hurried admonitions fell on deaf ears as her son continued to grope... Yes, he kept groping over and over again...!!
