HUNTB-627 My sister-in-law only lets me have sex. My new sister-in-law who started living with me doesn't talk to me at all. She won't even make eye contact. It's always just sex.

After meeting and having sex with my sister-in-law just a few days later, I've been having sex with her ever since. Despite living together, there's no conversation between us as family. Our relationship is purely sexual. When I confronted her about what she was thinking, my sister-in-law simply said, 'Because it's embarrassing...' It turns out that her cold attitude was a misunderstanding; she's just shy! How cute is this sister of mine! I've grown even more fond of her!
