My cute little sister was taken away by the neighbor's brat... and I was powerless to stop it. (Miyazawa Suzu NTR-053)

Miyazawa Rin and her brother had been annoyed by the noise of the neighborhood kids for a long time. One day, when her brother was not around, they actually took advantage of her body and fucked her. When her brother came home and saw what happened, he was so shocked that he couldn't move. He even got a big erection from seeing his sister's lewd posture. This made his sister gradually fall in love with being slept with!
