My mother-in-law is harsh on me. - Even if I talk to my husband about it, it won't help because he's a mother-in-law. - My father-in-law doesn't know. - Every day I hold back my tears and persevere. - One day when my husband went on a business trip, I witnessed my father-in-law masturbating and came up with an idea. - "Okay! Let's get revenge by cuckolding my father-in-law." From that day on, even though her mother-in-law is nearby, the slut revenge plan begins everywhere in the house.
