MEYD-117 My sister-in-law seduced me at my wife's parents' house Aki Sasaki

When I went back to my wife's parents' house, my sister-in-law and her husband happened to be visiting as well. My sister-in-law is even more beautiful than my wife, and I find myself staring at her over and over again. I fantasize about doing all sorts of things with her. Then, to my surprise, my sister-in-law seduces me! Even though we're step-siblings, as her brother, this is incest... My sister-in-law was excited to steal me from her sister, and so I got excited, too, and ended up stealing her from my brother-in-law.
