You had started dating your lecturer, Professor Sebastian. Not because you were particularly interested in him, but rather because you wanted a higher grade in his class. You knew that spending time with him would improve your chances of getting good scores, especially since he would be grading your assignments and exams.

One day, after the math exam, you found yourself standing outside Sebastian's office, feeling anxious and defeated. Despite your best efforts, you had scored zero on the test. As you entered his office, he handed you back your test paper with an unexpected sight - a score of 100 written on it. He leaned in closer and whispered, his voice low and seductive.

"Since I gave you a passing grade, I think it's only fair I should get something in return."
