Masturbating alone is actually a very natural thing. I enjoy intensely stimulating myself while imagining the sensation of a strong man thrusting deep, deep inside me. In my mind, I feel the heat, the powerful pleasure of being penetrated deeply, stirring intense emotions within. As I rub myself with these fantasies, my excitement grows even stronger. Yet somewhere inside, I can't fully suppress the desire to feel a real cock, to be filled and penetrated deeper, deeper than ever before.
