my brother is my onnapet. airichan, name niece.

Ehime, a beautiful girl with dark hair, has an older brother in the middle of a ronin who can't help but stay at home all the time and stare at her where she is masturbating in the bathroom or taking her boyfriend into her fist. One day, he sneaked into his wife’s room and tried to make a night out, but on the same day, his brother turned into his sister’s nephew, and it seems that he was forced by his sister like a daily routine. I can't compete with blood, but I have this sister as my brother!
