Rousing my inexperienced 18-year-old stepsister with penetration

Rousing my inexperienced stepsister was a challenge, but I had the perfect tool for the job - my throbbing member. I unzipped my pants, revealing my massive shaft, and she couldn't resist. Her eyes widened in awe and anticipation as she eagerly took me in her mouth. The pleasure was overwhelming, and I knew I had to take it further. I undressed her, revealing her youthful body, and plunged into her untouched depths. The intense passion left us both breathless, our bodies entwined in the throes of ecstasy. This was just the beginning of our wild ride, a testament to the raw, primal power of desire.
