Memories Of School.

In my last year of high school I got caught showing off my large cock to a girl who had the hots for my dick.
Sent to the headmasters office, he didn't have the time to deal with me, so I got sent over to Mr D, our physical education teacher.
He had a reputation for being tough, but when I gave him the letter from the head master and he'd read it, instead of punishing me, he had me remove my trousers and boxers in the gyms changing area.
At first I thought it was to try and humiliate me, but when he stepped closer and began stroking my cock making it hard, I knew he wanted something different.
Kneeling in front of me I received my first gay blow job. And trust me Mr D was extremely good at sucking dick.
Telling him I was cumming after only a couple of minutes, he just carried on until my cock exploded in his mouth. And my gym teacher swallowed every drop of my spunk.
Standing up, he smiled at me, had me kneel down and watch as he took out his cock.
It wasn't as big as mine, but it was thicker. Pushing it between my lips, I opened my mouth and tried to copy what he'd done to me.
He lasted much longer than I did and for some time I was taught how he liked his cock sucked.
When he came, Mr D gripped my head and told me not to let any seep out of my mouth.
His cum tasted weird, but not bad as I swallowed his load and thought to myself it actually felt good sucking his cock.
When he withdrew, he pulled me up and we went into his office.
He said the head master had told him to find the appropriate punishment, so he came up with each time he had a free lesson or at lunch times, I'd attend the gym.
Over the remaining time I spent in high school I had sex with Mr D.
Some days he'd suck me dry, other days I'd be on my knees draining his balls.
But after a few weeks he took my anal cherry.
It was an awful wet afternoon and he was extra horny. He used hand cream after first tonguing my arsehole, then slowly entered me from behind as I knelt on the changing room bench.
It hurt at first, yet I wanted him to fuck me and soon enough it began to feel amazing.
From then on each time we got together he'd fuck me, and each time I'd spend the rest of my school day with his spunk leaking out of my arse.
For about a year after I left passing my exams, Mr D and would meet up at different places and we'd have sex.
One time we got caught by a male dog walker as Mr D was fucking me in the woods.
The guy just stood there watching and wanking until he shot his load all over the floor.
This was all forty years ago and Mr D is no longer with us. He passed away several years ago and I attended his funeral.
I'm now in an open marriage, one where my wife has lovers and I go cruising for cock.
We both except each others needs, and it works for us.
The reason I'm confessing this, is forty years ago I took my last exam at this time of year.
Mr D had me visit him at his office next to the gym before I took my history exam. He fucked me over his desk and sent me on my way with his semen deep up my arse.
Half way through the exam his spunk leaked out and I had to scurry along once the exam finished.
