Teacher Visits Me at My House and Tells Me That I Failed His Subject and There Is Only One Way to Pass

I thought he was just coming to talk about my grades... But my teacher had other plans. He looked me in the eye and said, "You have failed... but you can still pass, if you do exactly what I tell you." I couldn't say no. I submitted to his rules, he used me mercilessly and every second was recorded. Dirty sex, total domination, and a student desperate to save the semester.
