MEYD-589 A cold sister-in-law in front of my brother, but actually a fuck buddy. Living together with this tsundere roommate.

A woman who is somewhat cold to me, beautiful and big-breasted but a bit difficult to handle, my sister-in-law Meguri. One day, while I was watching AV, she suddenly entered my room (sweat. And for some reason, she didn't leave and ended up watching AV with me! That night, 'You're responsible for keeping me awake' (smirk) my sister-in-law came to my room, and we crossed the line, starting our secret sex life together! Is her cold attitude around family a strategy to avoid getting caught by her husband? Or is it just shyness? A completely subjective, forbidden relationship of constant sex! Living in sin with my insincere sister-in-law!
