"Sure," I said finally, settling in to watch a movie with Mia.

As I walked into the living room, I couldn't help but notice my step-sister, Mia, bouncing around in her tight-fitting yoga pants. Her perfect ass was jiggling with every step, making it hard for me to focus on anything else.

As we sat on the couch together, Mia's bouncing ass became a distraction I couldn't ignore. I found myself stealing glances at her, appreciating the way her body moved with every shift in position.
