My father remarried three years ago. He had a daughter who was five years younger than me, and she lived under one roof with my father, mother-in-law, and sister-in-law. My father and mother-in-law wanted to have children of their own, and the sounds of sexual intercourse echoed through the house at night. When she woke up in the middle of the night to use the bathroom, she peeked into her parents' room and saw her sister masturbating.... After that day, my sister came to me and said, "I want to do you, big brother..." She showed her young body to me and seduced me.... I can't keep my rationality, and I end up having sex with my sister without telling my parents.... My sister's love for me became more and more distorted day by day, and she started to manage my ejaculation once every three days....
