My stepsister entices me to penetrate her tight rear end with my substantial member

My stepsister, a stunning teenage vixen, has been driving me wild with her seductive antics. She's been dropping hints, teasing me with glimpses of her luscious rear end. I've been trying to resist, but her allure is too strong. Today, in the confines of our dorm room, she finally took it a step further. She led me to the bedroom, her eyes sparkling with mischief and desire. She playfully stripped down, revealing her flawless body, her tight rear end beckoning me. I couldn't resist any longer. I took her from behind, my substantial member finding its home in her tight rear end. The sensation was overwhelming, a mix of pleasure and naughtiness. We moved in a rhythm, our bodies entwined, our breaths hitching as we reached the pinnacle of pleasure. It was a moment of pure, unadulterated passion, a testament to our insatiable desire.
