The classroom door locks behind them, sealing in the illicit, charged atmosphere. The student, his heart pounding, unzips his professor's pants, revealing a thick, veiny cock straining against his briefs. He runs his hands over the professor's length, feeling the heat and hardness, before taking the tip into his mouth, swirling his tongue around the sensitive head. The professor, his eyes closed, enjoys the sensation, his student's eagerness evident in every sloppy, wet suck.
