I, a university student, seduce my non-related stepsister after her European trip with intense sex leading to orgasm

As a young university student, I've always been intrigued by my stepsister, who's not even related to me biologically. The thought of her has been consuming my every waking moment, especially after her recent return from a steamy European trip. I've been fantasizing about her voluptuous curves and the secrets she might be hiding. When we finally found ourselves alone in my dorm room, the tension was palpable. I couldn't resist any longer, and I made my move. Her initial shock quickly turned into desire as I revealed my plan to explore her sexually. Despite being an amateur, she was more than willing to learn. As we engaged in passionate lovemaking, her moans filled the room, a clear indication of her pleasure. The intensity grew, and she soon found herself on her knees, begging for more. The climax was explosive, leaving her in a state of ecstasy. The experience was unlike anything I've ever known, and I'm left craving more.
