I couldn’t wait to be 18. Everyone kept telling me how much fun I would have at that age, but I didn’t believe it until my stepdad and stepsister got me my birthday gift. Now that I’m a woman, I’m old enough to be a part of their little secret. Apparently, they’ve been hooking up for a long time, and now, I was finally able to join them. I didn’t know if I was going to like fucking, but the second my stepsister took my top off, and my stepdad put his fingers inside my tight pussy, I knew I was about to have the best birthday ever. They even got me a butt plug! I’ve never had anything inside my ass, but my stepdaddy knows better, so if he thinks I’ll love it, I’m sure I will. Besides, I want to get my butthole ready for his dick. I’ve heard anal sex is the best gift someone can get.
