A curious and horny teen, alone in her room, decides to experiment with her body. She starts by sliding a thick, black Sharpie into her tight ass, grimacing at the initial discomfort but soon finding pleasure in the unique sensation. Her pussy, already dripping, begs for attention. She moves the Sharpie in and out of her ass while rubbing her clit with her other hand, her moans echoing in the room. The contrast of the cool plastic and her warm, wet pussy drives her wild.
