Hidden behind the partition, the teen's heart races as she hears footsteps. A thick, uncircumcised black cock slides through the gloryhole, and she eagerly takes it into her mouth. She's never seen one this big, and her inexperience shows as she struggles to take it deep.

She swallows it all, her eyes watering, a sense of accomplishment washing over her.
