My History teacher suggested a little roleplaying porn for me to make up my failing grade in his class. He was very persuasive in how our reenactments would certainly guarantee me a better sense of History and a passing grade.
So the scene was for me to stay after class and do a little Cheer as I listed off the 50 states and their capitals. Well, whenever I got one wrong I had to perform some extra credit. I managed to get 25 wrong so he decided I needed to do 25 minutes of servicing his cock.
My starting point was on my knees in front of Mr. Todd and performing falacio. I sucked his cock and licked it until he spilled a load in my mouth. I was pretty good and so there was still 20 minutes left. I think you need to tell me I should continue the remaining 20 minutes.
