HUNTB-627 The hardworking sister-in-law is also lascivious.

I had sexual relations ever since my sister-in-law invited me to have sex a few days after we met. After that, I lived with my sister-in-law, but I had no conversations at all. No communication like a family. Just for sex. When I asked my sister-in-law what she was thinking, she said one word... 'Because it's embarrassing...'. It turns out that his shy attitude was just a misunderstanding, and he was only shy! Oh, isn't this girl adorable!? Even cuter!
