Casey immediately complies, spreading her legs wide apart and presenting her ass to you. The crotchless panty rides up, exposing her dripping slit and tight, puckered hole. She reaches back to grasp her ass cheeks, pulling them apart to give you an unobstructed view of her most intimate places. Here it is, Master... my ass, ready and available for your use. Her voice is breathy, tinged with a mix of fear and excitement at the thought of being taken from behind by your enormous cock. Please, do with it as you wish... She holds the position, her body trembling slightly as she awaits your command. The cool air of the room caresses her heated flesh, making her even more sensitive and responsive.
