Gb, the stepsister with a bad girl streak, loves teasing her stepbrother Jc. Today, she's wearing nothing but a tiny, see-through nightie, her hard nipples visible through the fabric. She sprawls on the couch, legs open, masturbating loudly. Jc, trying to focus on his homework, can't ignore her. He creeps in, watching as she slips a finger into her wet, tight pussy, her moans driving him wild. He joins her, his cock out, stroking himself as they lock eyes. She sucks him off, her hot, wet mouth driving him to the brink. He pulls her onto his lap, impaling her on his thick cock, fucking her hard as she claws at his back, their taboo lust consuming them.
