I've been having sex since my sister-in-law invited me to have sex a few days after I met her. Since then, I haven't talked to my sister-in-law at all even though I live with her. There is no communication as a family. In a relationship where you only have sex. When I dared to ask my sister-in-law what she was thinking, my sister-in-law said, "I'm embarrassed ...". It turns out that the attitude that I had been toun until now was a misunderstanding, and I was just shy! Isn't this sister cute? It's even more endearing!
