I allowed my instructor to penetrate my tight vagina for a grade

I was struggling with my grades and decided to take a drastic measure. I approached my instructor, a man of considerable means, and offered him sexual favors in exchange for a passing grade. He agreed, and as a first step, I eagerly gave him a deep throating blowjob. He was impressed by my skills and proceeded to penetrate my tight vagina. It was a rough, intense fucking that left me moaning in pleasure. He took me from different angles, including doggy style and missionary positions, all the while thrusting his massive cock deep into my pussy. The experience was overwhelming, and I found myself surrendering to his every desire. When he finally reached his climax, he released his hot load all over my face, leaving me covered in his sticky essence. It was a wild ride, but one that ultimately led to my desired grade.
