Myself (21) am an undergrad student. Like anyone, I also discovered masturbation by myself when one random stroke felt good. From that moment it has been my go-to stress reliever tool.

This happened during my finals for database management systems and was shocking for me at first. Prior to the test, I had gone for a few days without jerking as I was caught up in its preparation. I didn't feel like busting a nut as I was so stressed about it. I was having a hard time understanding different queries and numerals related to them to the point that my brain was fried. With lots of effort somehow I was able to prepare well.

On the day of the exam, as I was giving my test I had a random boner pop out of nowhere. I had worn tight fitting pants which made it worse as my penis constantly rubbed against the fabric and the fact that I haven't busted a nut for more than a week alleviated the sensations. I knew if I didn't take care of it I won't be able to concentrate. It was an agony that I wished I could get out of asap as time was running out. The only option I had was to fucking cum to relax myself and I could simply do it in the washroom but the coordinator was strictly refusing saying it was against the rules of the institution to let someone out of the room as the test already started. I had no other option but to sit throughout the test with a bulge in my pants trying not to cum in a class full of peeps. I was so tense as I had already lost some time with this. All this time I could feel a weird sensation down there as if something was getting bigger in my groin. This feeling started growing till I involuntarily started tensing my muscles down there. Thinking back I don't even know what I was doing at that moment, it was like my subconscious mind took over me, or the adrenaline I don't know. This sensation only grew as I tensed my muscles down there and within a few seconds, I could feel I was so close and busted a huge load in my pants. I dipped my head as it happened to save myself from the embarrassment. Without even touching I could say my underwear was soaked as fuck and a stain had formed on my pants. I was discrete so I don't think anyone noticed but the wetness in my pants was evident. I had to sit there with them for an hour to get out for clean up. I was so fucked at that moment and was shit embarrassed. It was quite a shock for me to even think that I came while writing an exam of all places.

Sorry for being too graphic and detailed, thinking back this incident still makes me kinda horny.
