My [f]irst sexual experience was also my [m]aths teacher, and helped me discover my love for humiliation and bjs.

This story took place a little under a year ago while still at school. One of my classes were math and they were held by a man in his forties (maybe late thirties?). I have always struggled with math and near the end of the year my grade was dropping seriously hard so I was called into a meeting with this teacher to talk about how we could improve my grade.
This teacher was amazing and easily one of the best I’ve had the luck to experience. He was helpful, understanding and incredibly funny which made his classes much easier to follow.
So there I found myself, talking to this dude about my grade and what not and he cracks a joke per usual. I can’t really remember what it was about, I just remember it was so hysterical I bursted out in uncontrollable laughter. It was awkward but I could not stop myself. You know how it it when you try to stop laughing and it just makes you laugh harder? Yeah.
Now I suffer from struggling to control my bladder. Whenever I experience strong emotions or physical sensations I tend to “leak” a little. And as I sat there laughing my ass of I could feel it coming, except this time it wasn’t just a little, I full on pissed my pants in front of my teacher. I so vividly remember that moment because it was so humiliating. My face felt red with laughter and my ass and thighs became warm with my own piss. You could hear my pee as it hit the floor under my chair. Naturally as I was unwillingly relieving myself I managed to finally shut the fuck up because of the extreme shame I was experiencing. And oh boy was it quiet. I didn’t say anything as I was completely frozen in shock and my teacher just sat there staring with a blank expression on his face, probably processing what the fuck just had happened. I can barely remember what I said, but it was something along the lines of rambling sorry over and over again before scrambling to get to the closest bathroom. And now ladies and gentlemen, comes the fucked up part of my story. The moment that would reveal my love for cocks and humiliation. Because as I got up from my chair, and the way we were seated, I could see him from behind his desk with a full on raging boner. At the time being I was a virgin (late bloomer club yay) and didn’t have much experience with cocks and their antics. I remember being entranced at the sight of his bulge. The way it pressed against the fabric of his slacks. It.was.so.fucking.hot. And also, what the fuck my teacher got hard from watching me piss myself. I don’t really know what got into me, maybe it was the combination of being a horny young adult and for the first time in my life experiencing another person showing something resembling attraction towards me but I went over to him where he sat behind his desk and got on my knees in front of him. I remember just looking at him not really sure of what to do but placing my hand on his thigh. When he didn’t try to stop me I went further and took out his cock. As mentioned I was a virgin at the time but I was well read in erotic fiction (oof) so I managed to awkwardly fumble myself through my first blowjob – soaked in my own piss. And I enjoyed it so much, feeling him grow and fill my mouth, tasting him, hearing his breathing and moans get heavier as I went to work and finally got him all the way in my mouth. He seemed to enjoy it too, because he was trying to control himself from bucking his hips and gagging me. He got more comfortable after a little while, and started directing my head with his hands, and explaining what felt good to him. I was so turned on by the whole thing – him being much older and my teacher, me going from being so humiliated to so turned on, the smell of piss and his cock (romantic, right?). I felt desired, and filthy. He ended up spurting his load so hard it hit the back of my throat, and I gagged so violently it got all over him. After this I just got up and went to clean up, and we didn’t talk about it for weeks. Ended up sucking his cock a few more times (should I write about that to?) I still think about him all the time. And for those wondering, yes my grade went up, albeit from efforts other than mathematical equations.
