A curious brunette, hungry for knowledge, finds herself face-to-face with a dominant black cock professor. He towers over her, his thick, veiny member already hard and ready. She looks up at him, her eyes wide with anticipation, as he begins his lesson. He teaches her to worship his cock, guiding her hands, her mouth, her tongue. She learns quickly, her body responding to his every command. The final exam comes as he grabs her hair, fucking her mouth roughly until he spills his hot load all over her eager face, marking her as his student.
