my beloved sister-in-law, who I grew up with instead of a parent, was taken to bed by the worst friend... Sasao HATAKEYAMA

Tatsuo and I are not real brothers and sisters. my father was married again, and the child with him was jealous. After that, he lost his parents and lived together with his brother and sister. Now, the young Kaoru who was so small grew up to be such a beautiful woman. i liked such a sisterinlaw... Only Kenichi, his only best friend, confessed to such forbidden love. But that was a mistake. Kenichi got to know my feelings and had a hard time with me, showing me sex that seems to be insanely jealous at our house.
