I was in tenth grade and after my last class one day I stopped by the boy's bathroom to take a leak before heading home from school. I stepped up to a urinal and this really handsome senior who played soccer was standing two urinals down. I knew him because some of my friends played soccer but we were not buds or anything because he was a couple years older than me. I unzipped my jeans and pulled my cock out to piss and just then he said "dammit my dick is so hard I can't pee...don't you just hate it when that happens?" Then he stepped back to show me his hardon, and he must have been packing about 9". I just shook my head and laughed.
But of course I immediately started getting hard. Then he said "is your dick hard too?". I am pretty sure he already knew the answer to that question but I said "yeah, thanks a lot". He laughed, then turned toward me with that massive boner sticking out of the fly of his boxers and started stroking his cock. I turned to face him and started stroking mine then after a minute or so he moved closer and said "hey bro lets stroke em together." So we moved closer until our cocks were side by side touching each other and we rubbed them together and stroked. His dick was so long the head had actually slipped inside the fly of my boxers while we were stroking. After a couple of minutes he said OMG I AM GONNA BLOW! and suddenly I felt a warm wet sensation around my pubes as he pumped several jets of hot cum into my shorts. Then he leaned in and kissed me on the lips. That sent me over the edge and I blasted my load all over his dick and the front of his boxers.
The bathroom had two doors and just then we heard the outer door open and guys talking so we quickly turned back to face the the urinals like we were pissing. Then these two guys, one of whom I knew, barged into the bathroom and seeing two of the three urinals occupied headed for the stalls. One of them said "Damn dude it smells like cum in here!" The other guy said "You moron it is the bleach the janitor cleans the toilets with." BAHAHAHAHAHA!!!!
Soccer stud and I both quickly flushed, zipped up, washed our hands and got the hell out of there before they came out of the stalls. LOL
