MEYD-155 While you're away at work, I'm being tied up and trained by my master... Azuma Rin

Just once...Looking for excitement, beautiful wife Rin casually met a man on a dating site and had sex in a hotel room. After that, they met several times, and the man even started showing up at her house. Tied up and verbally abused and trained, Rin eventually became obedient to the man, and a master-slave relationship was born. Rin, who has a masochistic nature, finds pleasure in obeying her master, and her body becomes unable to escape the pleasure of being tied up!
