Sensual encounter with step sister in nylon while she was tidying up

Step-sis visits, tidies up, and teases with her alluring nylon-clad legs. Unexpectedly, she's taken from behind, indulging in a forbidden, kinky encounter with a man claiming to be her non-existent brother.

I had just gotten back from the gym and was about to head upstairs to my room when my step sister walked in, seemingly out of nowhere. She was busy tidying up when I decided to strike up a conversation with her. As we chatted, I couldn't help but notice her shapely legs encased in nylon, making them even more alluring. My curiosity got the best of me, and I asked her if she would be willing to show me what she had underneath. To my surprise, she agreed and proceeded to lift her skirt, revealing her perfectly shaped ass in those tight nylon pants. The sight was enough to ignite a fire within me, and I couldn't resist the urge to take her right then and there. I pushed her up against the wall, pulling off her panties and thrusting inside her. The sensation of her soft cotton jeans against my skin only added to the thrill of the encounter.
