Stepsister's big butt makes it hard to hold back

As I returned home from work, I was greeted by my stepsister lounging on the couch. Her voluptuous curves and enticing bubble butt were impossible to ignore. In my mind, I envisioned a forbidden fantasy of taking her right there on the couch. But, as I approached, she revealed her true colors, not the innocent stepsister I thought I knew. She was a shameless vixen, ready to indulge in a taboo family affair. Her dark, alluring eyes dared me to explore her forbidden fruit, and I couldn't resist the temptation. Our encounter became a wild, lustful ride, filled with intense passion and raw desire. The sight of her ample ass bouncing as we made love only fueled my insatiable hunger. The climax of our encounter left her covered in my hot, sticky cum, a testament to our steamy rendezvous. But, as quickly as it started, it ended. She returned to her demure self, leaving no trace of our erotic escapade behind.
