THTP-080 Forbidden incestuous SM

This work is a collection of submissions from sadistic gentlemen and masochistic women who indulge in incestuous sex and abnormal SM play.
Mirai (alias), the new bride being trained by her brother-in-law, was discovered masturbating while watching SM-themed adult videos. From then on, she began to be trained by her sadistic brother-in-law. Although she has a strong sex drive, she just can't feel anything during normal sex; it's because I have this twisted desire to be a masochist. She thought. It didn't take long for her to fall into her brother-in-law's hands and even start wearing a remote-controlled vibrator in front of her husband. "This is fate," she realized that she couldn't escape the relationship described by her brother-in-law.
