Eriko treated her son like a child for far too long. One night, after he returned home late from a drinking party, they got into a heated argument and he locked himself in his room. He finally snapped, shouting, "I'm already 20 years old! Stop treating me like a kid!" Trying to apologize, Eriko went to his room, only to accidentally walk in on him masturbating. Caught in the moment, her son said, "I'll make up with you, but only if you let me see your breasts." Unable to resist, Eriko gave in to his demand.
