Karla's mind drifts to forbidden thoughts as she sits on her bed, her hand wandering beneath her skirt. She pictures a massive, throbbing cock, one she knows she shouldn't crave. She slips off her panties and spreads her legs, her fingers finding her slick folds. She imagines the cock filling her, stretching her, as she fucks herself with her fingers. Her body aches for more, but she knows she must resist. Yet, the taboo thrill only heightens her pleasure, and she can't help but let out a soft moan as she brings herself to a shuddering climax.
