MEYD-561 Nanami Kawakami lives together with her sister-in-law who is cold in front of her brother and is actually a tsundere with a sex friend.

Nanami, my brother's wife, who is beautiful but a bit cold to me, is kind of cold towards me. - One day, when I was watching an AV, she suddenly came into my room (sweat). And for some reason, she didn't go out and decided to watch an AV with me! That night, she said to me, ``You should take responsibility for not being able to sleep.'' - She crossed the line with her sister-in-law, and started a secret sex friend life! Is her awkward attitude when she's with her family a way to hide her shyness from her husband? Be honest! - Domestic affair living together with brother's wife who doesn't exist!
