Overview

Immediately after his sudden turn of events, his mother remarried and he suddenly had to live with his stepfather and sister-in-law. When her older sister Mai saw her servant for the first time, she was stunned. She said, ``I never heard that he was going to have a younger brother. I thought he would be around the age of a student.'' She may have been worried about living with such a big brother. I felt a little sorry. However, after a week had passed, perhaps because we were living together, my sister started wandering around the house wearing a housecoat that looked like underwear and had her big butt sticking out. "Don't stare at me. I'm at home, so it doesn't matter how I dress, right?" No, no, I can't stand it if you dress like that! I was defenseless and suddenly got an erection in my ass, so I hurried back to my room and masturbated. My naughty older sister, who knows about my sexual situation, shows off her erotic ass every day. My older sister was napping on the sofa in the living room with her butt exposed...I accidentally touched her older sister's big butt...it was so soft...it looked like it would become a dangerous habit...I was massaging it in a frenzy when my older sister noticed it. I woke up. "Hey, what are you doing? Stop...we're sister and brother, aren't we?" I know that...but my rational mind is gone...I'm sorry, Mom! But I can't back down anymore! ! I bury my face in the soft butt meat, rub my crotch against the crack of the butt, and insert it completely from behind... It's crazy... I can't stand the feeling of this butt meat rippling... It feels so good that it pistons furiously! Without thinking about the consequences, I injected a thick layer of semen deep into my sister's vagina...I did it...incest...The family was destroyed...The next day, my sister was calm. I didn't feel bad for my parents...Maybe they didn't like me? I got carried away by her and started chasing her older sister's butt, stealth from her parents' eyes...
