If only I had talked some sense into him back then… After my son caught me masturbating, I accepted the demanded erotic act to keep him quiet. Shiho (Akiyama Shiho) regretted it deeply. Since then, my son's desires became uncontrollable. He would latch onto my breasts, drink my milk, and demand sex. Resigned, Shiho agreed under the condition of 'just the tip.' She thought that if it was just the tip, she wouldn't have crossed the forbidden line.
