The locker room echoes with the sound of her stepbrother's heavy breathing as she drops to her knees, his massive cock already in her hand. She licks her lips, tasting the salty pre-cum beading at the tip, before taking him deep into her mouth. She bobs her head, her tits bouncing with each thrust, until he's groaning her name. She feels his cock pulse, and then he's filling her mouth with his hot cum, some escaping her lips and dripping down her chin.
