Is it normal to fantasize about sister in law?
Recently, I have been fantasizing about my wife's sister. I love my wife and I will never ever think of doing anything to hurt her, and i do not like her sister for a relationship or anything, she is just not the kind of girl I would ever comsider dating. But whenever she comes over I cannot stop looking at her cleavage or legs when she wears shorts. I think it is just the idea of someone younger, she is 19 and i am 22. In any case, i do feel horrible for having this thoughts, mostly because i worry that is only me having them and that makes me a horrible person.
