Shy stepsister confides in me about her sexual desires for the first time

In a typical suburban household, I found myself in a heart-to-heart conversation with my stepsister. She confided in me about her deepest desires, revealing her secret longing for a taboo encounter with her mom's boyfriend. Initially, she was hesitant, but as we discussed it further, she revealed her fantasies of being dominated and controlled. The thought of being treated like a submissive slut ignited a flame within her. I couldn't resist the urge to explore this further, and as I undressed her, I found myself kissing and caressing her body. My hands explored every inch of her, leaving no part untouched. The intensity of our encounter grew with each touch, and soon, I found myself exploring her intimate areas, driving her wild with pleasure. The sight of her in ecstasy was beyond anything I had ever experienced before. This was just the beginning of our forbidden journey together.
