<human>: This was from a few years ago but I thought it was a fuck up enough to share.

We've all gone through our teenage years. They're really confusing times where you can be mega horny at any time of the day and be turned on by anything. Thus, school can be a really confusing time for some guys. Our schools' uniform didn't help, the girls wore white blouses so you could often see the bras underneath then. This led to teenage me getting fairly horny in lessons sometimes, especially boring ones where the teacher would just make us watch a DVD or lecture for the entire thing.

So anyway, I found out in several lessons that there was a way you could sit in the chairs at school and have a boner and you'd just need to tense a few muscles to get it rubbing against the fabric of your trousers and it'd feel good. I would usually do this in a couple of the more boring lessons where I was situated at the back of the classroom and it'd be a sort of quiet, lecture type environment, namely Geography or German.

Anyway, one of these boring Geography lessons we were made to watch some DVD about third world countries or some boring stuff. It was a dull winters day and very overcast, and I was on a table on the back row on my own. My crush was in plain view and she was wearing her trademark lacy black bra that I could see under her white blouse. So naturally being a horny teenager, I started my little routine.

This time, being an hour long lesson I may have gone a bit too far, and I built it up, looking at my crush for about 40 minutes before exploding in my pants. Right in the middle of the lesson. I'm pretty sure she turned round and looked at me at some points of it too.

Anyway, bad decision because now I had a sticky mess in my pants and serious leakage. I instantly regretted it but had to continue the day at school with this white mess in my pants. I'm sure someone in the class must've noticed it but I'll never know.

Can you provide a brief rundown of the text in within 3 sentences?
<bot>: jerked it in school to my crush, had to walk around with sticky pants all day after. oh the shame.
