A woman who is a bit cold to me, beautiful but somewhat difficult to deal with, my sister-in-law Nanami. 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 (smile)' she came to my room, and we crossed the line, starting our secret sex buddy life! Is her cold attitude around family a strategy to avoid being found out by her husband? Or is it just shyness? A completely subjective forbidden relationship! Living in sin with an insincere sister-in-law!
