[Reducing Mosaic]DASD-753 My mother-in-law pisses me off to no end. A brilliant idea for a vengeful young wife. 'Can I mess with my father-in-law's crotch as much as I want?' Morihiko Jiku

My mother-in-law is hard on me. Even if you talk to her husband, it's useless because he's a mother's boy. Her stepfather pretends not to know. Every day I endure and endure tears. One day when her husband went on a business trip, he witnessed her father-in-law masturbating and had an idea. "Okay! Let's take revenge by sleeping on my father-in-law." From that day on, even though my mother-in-law is nearby, the slut revenge plan begins everywhere in the house.
