It's Not The Same Now

One day about two years ago, I went home to my parents to visit. My wife was going to meet me there in a couple of hours. My parents were not home, but my stepsister, who was in college, was home for the weekend. She was in the bathroom taking a shower. She did not realize I came there while she was in the shower. She came out of the bathroom stark naked and walked down the hall to her old room. She didn't see me at all! The door to the bedroom was still opened a crack, and my curiosity got the best of me. I strolled down the hall and peeked through the door. She was sitting on the edge of the bed rubbing herself between her legs. I couldn't believe she was masturbating in the middle of the day at our parents' house! I couldn't help myself, so I started to masturbate also while watching her. I got so out of control that my hand slipped off and hit the door. As it swung open, she jumped off the bed and looked at me. I'm standing there with my stuff hanging out and she is plumb naked. I saw her eyes glance down at my package and then back up at me. I guess, because we were so caught up in the moment, we just continued with each other. I know that was crazy. She is married now, and at family get togethers, we can never look at each other the same now.
