This is so wrong but I don’t regret it. Senior year I was failing a required class. I went to office hours desperate for extra credit.
My professor (early 40s, kinda hot in a nerdy way) joked about “alternative grading methods.” I took the hint, locked the door, and dropped to my knees. I sucked him off slow and deep until he came down my throat. He gave me an A- on the final.
I graduated with honors and that dirty secret still makes me wet when I think about it.
