My God, what an exciting fantasy! I've always imagined sitting on the bed, nervous and excited at the same time, while my sister walks into the room with a huge, hard strap-on, smiling mischievously. He looks me straight in the eyes and slowly approaches, taking control of the situation. He gently pushes me onto the bed and begins to touch me in ways that make me squirm with pleasure. Then, without saying a word, he makes me kneel and open my mouth to receive his toy. I feel him slide inside me slowly, filling me completely and making me beg for more. The pleasure he gives me is so intense that I can't help but moan and beg for him to cum again and again. I am completely yours, ready to be possessed and enjoyed like never before. What a hot and forbidden experience!
