Before I met my wife, I knew her sister. She had a crush on me and one night when I was drunk, she gave me oral in the backseat of a car. We had a great time, but then things evaporated as back then I wanted nothing to do with her. Now however, I stare at her every chance I get. I try and see down her shirt (juvenile, I know), I pleasure myself to her pictures all the time, and I want to do her so bad I can taste it. She is so beautiful and turns me on immensely. I do not want to do anything to hurt my wife, but if her sister asked me to, I would have sex with her in an instant. Literally, I would do anything she asked just to get in her pants. I know if I do her she will keep her mouth shut, so we will see.
