My step sister's disbelief of my large penis size

My step sister disbelieves my massive member until I show her. She's mesmerized and eager to try it. We engage in passionate, sensual lovemaking, with her eagerly taking me deep into her.

After a grueling workout, I found myself in a heated exchange with my step sister. She was adamant in her disbelief of the size of my manhood. As a man of honor, I decided to prove her wrong. With a devilish grin, I unzipped my pants, revealing my impressive package. Her eyes widened in disbelief, but I knew she was intrigued. The challenge had been set, and it was time to prove myself. I watched as she slowly approached, her petite frame trembling with anticipation. She took hold of my massive member, her small hands barely able to wrap around the girth. Her eyes were filled with awe and desire as she began to stroke me. Soon, her luscious blonde locks were cascading down her shoulders as she sank to her knees, taking me deep into her mouth. The sight of her eagerly sucking on my monster cock was enough to drive any man wild. Her tight, hairy ass beckoned me, and I couldn't resist. I plunged into her, my large cock filling her completely. The room was filled with the sweet sounds of our pleasure, a testament to the size of my cock.
