When I was a senior high school boy I was failing history class big time, as well as not doing very good in the rest. My first day there I had been made a bitch to this younger black kid, and between taking his dick, as well as a lot of his friends, I couldn't concentrate on studding. The history teacher was an older black guy, and one day when I handed in my test, he glanced at it, and asked me to hang around after class. History was last class, and I walked home, so I stayed. He said you know if you fail this test, you loose a credit, I said yeah I know, he responded with, well I know that you are Tyron's bitch, that made my face get hot. But he said Tyrone told me you really knew how to please a hard dick. He added that if I were to please his dick, I would get a good passing score on this test. So he locked the door, I got him hard, and while he sat in his chair, I straddled and rode his dick till he came in me. I got a c on the test, for some reason, my other class tests started to improve, I'm sure he had something to do with that also.
