I always had a thing for my stepsister, especially when she's being naughty. Today, she surprised me in the outdoor toilet, and we got carried away in a steamy public encounter.

I had to use the restroom while out at a restaurant with my stepsister. We snuck out to the outdoor toilet, and the sight of her using the bathroom ignited a fiery desire within me. I couldn't resist the urge to watch her, and she seemed to enjoy the attention. The thrill of getting caught only added to our excitement. As she finished, I wasted no time in taking her from behind, my hands gripping the toilet for support. The sound of her moans echoed through the empty restroom as I thrust into her, the cool tile beneath us adding to the sensation. The public nature of our encounter only fueled our passion, and we gave in to our primal urges. After a few intense minutes, we reached our climax, the release overwhelming us both. We cleaned up and returned to our table, our shared secret adding a new layer of intimacy to our relationship.
