I constantly fantasize about my mother-in-law. The thing is she's really not all that attractive, but I simply cannot stop thinking about her. My biggest fantasy is us being along in the house and me seducing her. I love my wife, however when we have sex the only way I can get into it is if I imagine it is her mother. As soon as I close my eyes and imagine her there, I can't contain myself. I honestly believe that I would be happier if I left my wife and ran off with my mother-in-law.
