I encounter my slender stepsister in the bedroom and she initiates foreplay to vigorously penetrate me anally and ejaculate on me

I stumbled upon my slender stepsister in the bedroom, and we found ourselves engaging in some steamy action. Despite the initial shock of our taboo encounter, we quickly got down to business. She was insistent on taking me anally, and I obliged, eager for a wild ride. Her big, luscious ass was a sight to behold, and I couldn't resist giving her a good pounding. As she squirmed beneath me, her tight hole enveloping my throbbing member, I could feel waves of pleasure coursing through my body. The sensation was unlike anything I had ever experienced before, and I found myself losing control as she continued to ride me. When she finally reached her climax, she released a torrent of hot, sticky cum all over my body, leaving me breathless and thoroughly satisfied. This was one encounter I wouldn't soon forget.
