Watching My Step-Sister

I came home unexpectedly one weekend from college. There did not seem to be anyone home, but then I heard noises from the family room. As I peeked around the corner, there was my step-sister and her future husband making out on the couch. I know I should have said something to them, but I just watched. I never told them I had watched them, but I must admit it is an image that comes up from time to time.
