A shy sister turns her webcam on, intending to practice her masturbation skills in private. She slips off her clothes, her hands exploring her body, her fingers finding her clit, rubbing it gently. She's lost in sensation when she hears a noise. Her brother has been watching, his cock hard and throbbing. She freezes, then, emboldened by her newfound exhibitionist side, she continues, pushing a dildo into her pussy, fucking herself for his eyes only. The room fills with the sounds of her wet pussy, her moans, his heavy breathing, until they both reach their climax, their bodies shaking with release.
