The mother harbored deep affection for her child, whom she had raised alone, but struggled with the lingering dependency of her son, who couldn't let go of breastfeeding. Her son continued to grope her overly voluptuous breasts every day. Though she felt uncomfortable, she tried her best to understand his emotions. One day, her son discovered her masturbating, and from then on, he began groping her breasts from behind even while she was doing housework. The mother panics, exclaiming, "No, stop it...!!", and tries to push him away, but her son ignores her protests and continues to grope her relentlessly.
