Input: Text: where the fuck do i begin. no, this was not from today, but i had just found this subreddit and this story needs releasing from my soul. 

so i'm a sophomore in high school, and i'm a horny 15 year old kid who does nothing when he gets home but jerk it to porn for hours straight and then pass out with mom wondering why i was asleep during dinner time. pretty typical millennial teenage kid i guess, right? 

well, one day, horny me decided it was a good idea to have wanky time in the middle of our classroom. we had this super fucking hot teacher with massive boobs and a great ass, we'll call her ms.ackson. ms.ackson taught digital info management and it was in this big computer lab that was set up in rows. i was in the row that was right by her desk. i'm talking to my friend, we'll call him chris, at the time and i notice that mrs. ackson is wearing these tight jeans that look so fucking sexy on her and a nice super low v neck sweater that just hugged her boobs ever so gently, i have a vivid image of it. my monkey was hard and ready to stroke, but the thing was, i couldn't stroke. 

15 year old me also happened to be this skater kid who wore skinny jeans a lot, and let me tell you, skinny jeans provide the best tension around your dick for sliding forwards and backwards and essentially jerk you off. well, chris decided he was going to talk to me about something and i continued to have a conversation with him while i was staring at mrs. ackson's ass. i slide back and forth in my jeans, pretty much jerking off my dick as i do so, and keep talking to chris just to make it seem like i'm not doing anything like that. well, it's time for the ol' banana to release it's juice, and i realize that if i cum, it'll be all over my black skinny jeans. fuck it, goes my 15 year old brain, it'll be super hot i thought. 

i cum and i close my eyes and drop whatever was in my hands (pretty sure it was my phone) on the keyboard and everyone turns to look around at me. chris i guess was still in the middle of a conversation with me and goes "dude, what the fuck?!" and i look down and the cum literally seeped through the threads of my tight fucking boxers and my skinny jeans and was literally there on my leg while my erect cock was basically blanketed by my jeans and fully outlined. chris is one of those kids that has an obnoxiously loud voice and laugh and shouts "dude are you jerking off?! ahahahahahahaha" in the loudest fucking voice possible. i quickly shove the cum off of my jeans which is now partially on my hand. mrs.ackson is like "do you need to go to the bathroom, ford_f150?" i dont even say anything, i just sprint out of the classroom and nearly break my dick by doing so, and go to the bathroom. 

i get to the bathroom, and not only are my boxers soaked, but my dick is completely chafed on multiple areas due to rubbing up against denim with high friction for so long. 

needless to say, i was known as that creepy kid who jerked off in the middle of class for the rest of the year.
