In the dimly lit gloryhole booth, a black chick tentatively reaches out to grasp the unknown cock that slides through the hole. She's never given head before, but she's eager to learn. She starts slow, licking and sucking the tip, her inexperience clear. But she's a natural, and soon she's deepthroating the anonymous cock, her spit and saliva dripping down her chin. She gags slightly, but she loves the feeling of being used, of being a good little cocksucker. She swallows every drop with a proud smile, her black lips glistening with cum.
