A mystery woman, her dark skin glowing under the dim light, finds herself in a seedy gloryhole booth. She's new to this, but eager to learn the art of deep-throating. Her inexperienced hands grasp the anonymous cock presented through the hole, guiding it to her full, moist lips. She tentatively licks, then takes it in, her gag reflexes testing her resolve. The stranger on the other side groans, encouraging her to take more, to go deeper. She obliges, her enthusiasm growing with each sloppy slurp.
