Innocent Crystal, new to the world of adult play, takes a deep breath as she positions herself on all fours, her tight, uninitiated asshole on full display. She tentatively reaches back, teasing her puckered entrance with her fingers, feeling the unfamiliar sensation. Her boyfriend, Jimbo19800, watches, his cock hard and throbbing, as he lubes up her virgin hole. Crystal gasps as the cold lube touches her, her body tensing. Jimbo slowly pushes the tip of the anal plug against her, feeling her resist. With a deep breath, Crystal relaxes, and the plug slips in, stretching her asshole wider than it's ever been. She moans, a mix of pain and pleasure, as Jimbo slowly fucks her with the plug, preparing her for more.
