Sumire Mizukawa (MEYD-758) fucks her neighbor's wife in a brothel where sex is prohibited.

The haughty, beautiful housewife who lives in the same building always looks down on me like I'm a slave and prioritizes herself above all else. Every day I get yelled at for trivial things, with things like, "It's infuriating to see someone like you, a nobody." What's with that awful woman? To relieve this stress, I went to a massage parlor, only to find out it was my neighbor, that housewife, who turned out to be me. From now on, it's time for my revenge.
