<p>My mother-in-law hit me hard. Even if I consult with my husband, it is useless because it is a mother's complex. My father-in-law doesn't know. Every day I endure tears. One day my husband went on a business trip, I witnessed my father-in-law's masturbation and came up with it. "Okay! Let's take revenge on my father-in-law." From that day on, even though my mother-in-law is nearby, a filthy revenge plan begins everywhere in the house.</p>
