I was in my stepsister's room, helping her slip into her favorite blue dress. The tight-fitting number accentuated her voluptuous curves, particularly her ample assets. As I zipped it up, I couldn't help but be drawn to her alluring backside. The sight of her in that dress ignited a primal desire in me. I found myself unable to resist the urge to explore further.Her eyes, filled with surprise and anticipation, mirrored my own as I began to unzip her dress, revealing her luscious curves. I took advantage of the situation, indulging in the forbidden pleasure of her company. I took her in my arms, feeling her luscious body against mine as we shared an intense moment of passion.The dress became a playground for our desires, as we explored each other's bodies in a way that only the heat of the moment could inspire. The sight of her big breasts and firm ass, clad only in her boots, was a sight to behold. The climax was nothing short of explosive, leaving us both breathless and satisfied in her bed.
