MEYD-518 — A Tsundere Cohabitation Life With A Cold Sister-In-Law In Front Of Her Brother, But In Reality She's My Sex Friend Airi Kijima

My sister-in-law Airi is beautiful but a little hard to get along with and is cold towards me. One day, while I was watching an adult video, she suddenly came into my room (lol). And for some reason, she didn't leave and we ended up watching adult videos together! That night, she came into my room and said, "You have to take responsibility for keeping me up at night///" and we crossed the line and started living as secret sex friends! Is her cold attitude when she's with her family to avoid her husband finding out? Or is she just trying to hide her embarrassment? A forbidden relationship where we do it all from a completely subjective perspective! An affair within the home with my brother's wife who can't be honest with me!
