[HUNTB-627] A sister-in-law who only lets me have sex. There is no conversation with my sister-in-law, who is newly living with me. They don't even make eye contact. Only sex forever.

I've been having sex since my sister-in-law invited me to have sex a few days after we met. And even though we live together, I don't talk to my sister-in-law at all. There is no communication as a family. In a relationship where you only have sex. When I asked my sister-in-law what she was thinking, she said, "Because I'm embarrassed ..." It turns out that the attitude that I used to have been toon is a misunderstanding, and I am just embarrassed! Isn't this sister cute! It's even more adorable!
