HETR-016 - My Father-in-law's Personal Sex Toy: A Married Woman's Secret

Tsubasa hides a dark secret from her husband: she is being kept as a personal sex pet by her father-in-law. While her husband sleeps, she is forced into degrading acts, and even during dinner, she's toyed with via remote-controlled devices. Once her husband leaves for work, she is leashed and trained like a dog, eventually breaking down and begging for her father-in-law's rough, relentless satisfaction.
