A horny teen boy, left alone at home, decides to indulge in some self-love, but this time, he's curious about something more. He grabs a thick dildo from his step-mom's collection and starts massaging his tight hole, his body tensing and relaxing as he probes deeper. His step-sister, overhearing his moans, joins him, her eyes widening at the sight of his big, hard cock. She takes over, her small hands expertly working the toy in and out of his ass while she strokes his length, their bodies pressed close as they both chase their release.
