Wtf?! Public with the Stepsister!

I had to take my stepsister with me on vacation and I didn’t feel like it at first, because she is always so prudish and can’t experience anything cool with her. But I had firmly resolved to change that! When we were on a cliff, I just kissed her and made it clear to her that I was going to fuck her here in the middle of public! At first she was very scared, but pretty quickly her pussy was so wet that she couldn’t help but fuck with me! What do you think, did I finally raise my stepsister to be a horny bitch?!
