I shagged my step-sister before school

So there I was last Wednesday morning about to go to school. I couldn’t find a clean uniform shirt anywhere so I went to the laundry room. I was about to walk in when all of a sudden I saw my Step-Sister Half Naked looking for clean clothes. She looked so fucking sexy standing there with her bare back to me. When she took off her panties and smelled them to see if they were clean, it was the hottest thing I’d ever seen. I couldn’t help myself and I started to jerk off right then and there. After about thirty seconds I was about to shoot my load all over the floor, but my step-sister turned around and busted me. At first she freaked out and yelled at me, but once she got a look at my woody, she got turned on as fuck. We Banged like wild animals for the first time and I shot my load deep inside her tight hole. Good thing it only took me a couple of strokes, because Step-Mom walked in right as we were getting dressed.
