Underage sister-in-law flirting. iin?
My sister in law moved in with my wife and me not too long ago. I have always seen her as a little sister / daughter, very protective of her and always there for her if she needed my help. Recently though, she has matured and is starting to say things and act differently when my wife is out of the house. She'll wear a low cut shirt or a short skirt. Not too long ago she was in the shower and she knew I was going to use it after her. She walked out of the bathroom in just a towel, crossed the hall to her room, and left the door opened a crack. All these little "hints" or "signs" only happen when her older sister, my wife, is out of the house. She's 15 and I am doing everything I can to ignore her while she does these things and am finding it hard to be alone with her. My brain says NO! DON'T BE FUCKING MORON!... But that other part of my brain telling me to act is getting louder and louder.
Thoughts?
