My brother and KAORI sister-in-law are a couple who are on good terms from my point of view, and my sister-in-law treats me very well. However, after seeing my sister-in-law having sex with my older brother's junior, my sister-in-law noticed it and suddenly gave me a blowjob, invited me to take a bath, and seemed to enjoy seducing me... If that happens, I can't take it anymore...!
