I am married. Going on 5 years this week. I have watched my sister in law grow from a snot nosed 15 year old into a 25 year old beautiful woman. She is at my house almost daily. I love my wife, however I cannot get my SiL out of my head. I feel like I am falling in love with her, or having a deviant fantasy. She has never had a significant other. She is a virgin and I REALLY want to be her first. I know it will NEVER happen, but the thought of it makes me fidget with anticipation. She has plans to move into our house after this summer, however I don’t know if I could stand it. I fantasize about her daily. I feel like I am sick.
