WTF?! PUBLIC with the STEPSISTER!

I had to take my stepsister with me on vacation and at first I didn't feel like it because she's always such a prude and can't experience anything cool with her. But I was determined to change that! When we were at a cliff, I just kissed her and made it clear to her that I was going to fuck her right here in public! At first she was very scared, but pretty quickly her PUSSY was so wet that she couldn't help but fuck me! What do you think, have I finally raised my stepsister to be a horny slut?!
