MEYD-589 [Uncensored Leaked] Meguri: Living with a Tsundere Sister-in-Law Who Acts Cold in Front of Her Brother, But is Actually a Sex Friend

My sister-in-law Meguri is beautiful and busty, but she's a bit cold towards me. One day, while I was watching some adult video, she suddenly came into my room (lol). And for some reason, she didn't leave and we ended up watching the adult video together! That night, she came into my room and said, "You have to take responsibility for keeping me up at night (lol)," and we crossed the line and began our secret life as 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 whatever we want from a completely subjective perspective! Living together in an affair with my brother's wife, who can't be honest with me!
