A secret tryst in the dimly lit room, the stepsister's eyes gleam with lust as she wraps her lips around her stepbrother's thick cock. She takes him deep, her throat muscles adjusting to accommodate his size. She loves the feeling of his cock hitting the back of her throat, her gag reflex kicking in but only spurring her on. She's insatiable, hungry for his release, her saliva dripping down his shaft as she sucks him with wild abandon.
