Nasty Sub, collared and bound, is presented with a daunting yet enticing task: to deepthroat the enormous BBC brought before her. She begins, her tongue lapping at the head, her lips stretching wide to accommodate the thick, veiny shaft. She takes it slow, inch by inch, her throat convulsing as it's filled. Her Mistress encourages her, "Take it all, slut. Show me you can handle it." Nasty Sub, dripping with arousal, pushes on, her eyes watering, her makeup smudging, but her resolve unwavering.
