Collared and eager, a bound beauty kneels before her mistress, eyes locked on the throbbing cock inches from her face. Her tongue darts out, tentatively tasting the salty pre-cum beading at the tip. She's a natural, taking the entire length down her throat, gagging slightly before finding her rhythm. Her saliva coats the shaft, her lips glistening as she bobs up and down, her bound hands clenching and unclenching with pent-up desire.
