The mother, raising her child alone, harbored a secret struggle—her son couldn't wean himself from her breasts, and she found herself enduring daily groping of her overly voluptuous chest by her maturing boy. No matter what she tried, the word "breasts" always came up in their conversations. One day, her son caught her masturbating to relieve her heated body. After that incident, he began groping her breasts from behind even while she was doing housework. The mother panics, protesting, "No, stop it...!!" and tries to reason with him, but the son refuses to stop. His behavior resembles that of someone completely dependent on his mother's body.
