My stunning stepsister demonstrates her dance moves in a skirt, and all I can focus on is her ample derriere swaying

I'm a lucky guy with a smoking hot stepsis who's a total stunner. She's a college student and my roommate, and she's always flaunting her killer body in the shortest skirts. I'm not kidding, it's like she's trying to drive me wild! The other day, while my dad was out, she decided to show off her moves in front of me. She started dancing around, swaying her hips and shaking her ass. I was completely mesmerized by her. She's got a big, juicy butt that just kept getting more enticing as she moved. I couldn't help myself, I had to have her. I took her from behind, slamming into her tight little pussy. She moaned and writhed in pleasure, loving every second of it. After a few rounds of hardcore sex, she even let me take her from behind, stretching her out with my big cock. She's a total ass fucking slut, and I'm the luckiest guy alive to have her as my stepsis!.
