One morning, Yuri Uesato, a mother, went to wake up her son and accidentally caught him masturbating to suppress his morning wood. Seeing that he kept ejaculating yet remained erect, she became so aroused that her panties got soaked. Unable to control her rising desire, she used her son's morning erection as stimulation and indulged in masturbation. That evening, the son noticed his mother's behavior and confessed that his penis had stayed erect all day long. The mother, equally excited by her own persistently hard, super-stimulated milf cock that hadn't gone down since morning, gave in to temptation, and right there, a new, incestuous relationship began between mother and son.
