There was only one thing my Math teacher had going for him, I thought, and that was his fantastic ass. That butt kept me going through Algebra; every time he bent over I seemed to find new energy, all over. Of course I never expected anything to happen, I knew teacher/student relationships were wrong, he could lose his job.
He was around 45, married, with a few grown up children I assumed. A shortish man, but quite slim. Dark hair, dark eyes, pretty cute for a 45 year old man I guess, but nothing special.
I was pretty normal too. An average body, shaggy brown hair, just finishing my last year of high school.
It was a pretty warm afternoon in May, I had Algebra last thing and it was pretty boring, aside from my teacher. I thought I had imagined it, as I probably had several times before, but I thought I caught his eye. He seemed to smile, but turned away straight away. I blushed a little, but put my head down and carried on with my work.
A few minutes later, I heard him talking to the girl in front of me. I looked up, his butt was right in my view. He had a perfect ass. Beautiful round cheeks that I just wanted to squeeze. I would give anything to have thrusted my dick up that butt at that moment, it was so hard and I was so turned on. I eventually calmed myself down, I wasn't going to walk out of that class with a full blown erection.
As he let the class out, he casually called me back to discuss some work, or so he said. He was sitting on the edge of his desk as I walked over, and I noticed him undo the top button of his shirt, he was relaxing. I smiled at him.
"Yes, Sir?" I said, pretty innocently. I had perfect grades, there was no real reason to keep me back.
"Oh it's nothing, I've just noticed that you've been pretty distracted in class lately. I don't want those grades to slip, that would be upsetting." He said, his voice seemingly earnest. I smiled.
