I never thought I was a mother from the beginning. ...I couldn't believe it. I was horny when I stole Kotomi's underwear. She peeked at Kotomi's changing clothes and indulged in masturbation.

That day, when I had just finished my father's funeral, I ran out of the house after attempting to rape Kotomi.
