This is sick and twisted, I've never heard of a case like this, even a suspected case.

My husband has only one brother and he is younger. Out of all my husband's siblings, I am closest to my brother in law because he is the most decent, friendly and doesn't engage in backstabbing behavior. He and I can talk for hours on end and joke about random things, he is like the little brother I never had growing up (he is my younger sister's age). We have the same taste in movies, same views on a lot of things, similar interests but despite all this I always observe hijab in front of him, no exceptions, and have never had physical contact, not even a handshake because he knows I am very strict about this. I don't think I've ever even sat on the same couch as him! Suggesting anything similar to the OP is sickening!

As for my husband and my little sister, it's a typical annoying big brother/annoying little sister relationship. They pick on each other all the time, smack each other when the other's not looking and shove ice down one another's backs.

Neither my brother in law nor my sister are married so I don't have a bhabi yet and my husband doesn't have a whatever-his-SIL's-husband-is-called.
