My step-sister's lazy day turns into a steamy encounter

After a long day at the gym, I returned home to find my 18-year-old step-sister lounging around the house with nothing better to do. Seizing the opportunity, I proposed a steamy encounter that she couldn't resist. She's been yearning for a taste of the forbidden fruit ever since we started living together last year. This college-aged beauty, with her luscious curves and irresistible charm, was ready to explore her wild side. As a young, amateur, and slightly self-conscious about her body, she's always been a bit of a mystery to me. But today, she shed her inhibitions and revealed her stunning physique, eager to indulge in some naughty fun. With her big, round ass and toned body from years of being a bodybuilder, she was a sight for sore eyes. The question was, could I handle what was about to come?.
