My petite stepsister learns to ride like a prostitute in my private room

In the private sanctuary of my dorm room, I was about to teach my petite stepsister the art of riding. The anticipation was palpable as I guided her to mount my throbbing desire. With each passionate thrust, she found herself lost in the pleasure, her body rhythm perfectly in sync with mine. As the intensity built, so did the desire to break free from the confines of our dorm. I could feel my climax approaching, and I knew it was time to bring her back to her own room. With a final push, I released my pent-up passion, filling her eager mouth with my essence. The sight of my mother and father in law on the couch below, oblivious to our intimate encounter, only served to heighten the thrill. As I retreated, I couldn't help but wonder if this was just a fleeting moment of youthful rebellion or if our shared desire would lead to more secret rendezvous in the future.
