Nikki's heart races as she enters the public restroom, knowing what awaits her. She positions herself in front of the gloryhole, her breath hitching in anticipation. A colossal, black cock pushes through the hole, pulsing with desire. Nikki moans, her pussy clenching as she leans in, opening wide to take the BBC into her mouth. Her head bobs, her tongue swirling around the sensitive tip, tasting the pre-cum that leaks from the slit. The cock grows harder, swelling in her mouth, as Nikki's enthusiasm intensifies.
