Mia had always been a bit of a brat, but I had to admit that her confidence and sassiness were traits that I admired. She knew she had a great body, and she wasn't afraid to show it off.
Bratty Sis - Step Sister's Perfect Ass Bouncing...
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.
"Hey, sis," Mia said, turning to me with a mischievous grin. "Want to watch a movie with me?"
"Sure," I said finally, settling in to watch a movie with Mia.
