The professor, a stern yet handsome man, has a reputation around campus for his unconventional teaching methods. Today, he's decided to put a student's oral skills to the test. The student, a young, nervous man, watches as the professor unzips his pants, revealing a thick, veiny cock. "This is the real final exam," the professor says, stroking his length. The student, understanding the assignment, tentatively takes the professor's cock into his mouth, gagging slightly at first before finding a rhythm, his head bobbing up and down. The professor grunts in approval, his hips bucking slightly, fucking the student's mouth.
