Back in college, I had a child with my first boyfriend. Despite the opposition from everyone around me, I decided to have the baby. Since then, I've raised my beloved daughter, Kaori, all by myself. I didn't want her to suffer the same hardships I did; I wanted her to be happier than anyone else. When my daughter introduced me to her boyfriend, Shinji, he seemed like a polite, serious, and decent young man. But my relief was short-lived. He took advantage of my daughter's absence and forcibly embraced me. I am her mother, so why... why is this happening? Caught between my maternal instincts and my desires as a woman, I felt a pleasure that was almost frustrating.
