My step sister joins me in the shower for a steamy encounter

After a long day at work, I was craving some self-pleasure in the bathroom. As I was about to indulge, I heard the shower running. To my surprise, it was my step sister, hiding behind the curtain. Initially, I was taken aback, but the sight of her bubble butt and luscious curves was too enticing to resist. We struck a deal - she could join me for a quick rinse if I promised not to tell anyone. We started chatting, and soon enough, the tension escalated. I couldn't resist the urge any longer and unzipped my pants, revealing my massive member. She was intrigued and eager to explore. With her oiled-up body glistening, she took my throbbing shaft in her hand, skillfully stroking it. The sight of my cock being worshipped by my step sister was intoxicating. We continued our steamy encounter, lost in the moment, until we heard footsteps approaching. In a rush, we quickly got back to our usual routines, leaving the bathroom with a sense of shared secret pleasure.
