My friend and I were seniors in high school at the time. On this particular day, we had gym instead of our study hall. We both chose kickball as our gym activity for the second half of the final semester, so we could stay together in the same class. After we all changed and attendance was taken, the game was on. We were lucky enough to be on the same team. After a little while, I felt like I needed to pee. Then, my friend quietly told me that he has to take poop. We were the last two in line to kick, so nobody could hear our conversation anyway, since we kept a little distance from the rest. Instead of asking to go to the bathroom, since we were close to the end of class, we just toughed it out for a bit longer. During the final position change, we both decided to sneak off the gym floor and into the locker room area. We decided now would be a good time, since we really wouldn’t be seen with everyone moving around. Normally, the locker rooms are kept locked to prevent theft, but our teacher forgot to lock the doors that day. We were able to go and do our business. My friend then blurted out once we got inside “man, if we didn’t leave now, I would have pooped my pants”. I then said, “why don’t you?” He paused for a minute and said “why not?” He paced back and forth for a moment, stopped in front of the lockers, and started pushing. He got this contorted grin on his face, as I could hear him grunting under his breath. I was getting hard watching him, which was making me want to pee even more. After he was finished, he told me to pee my pants, since I knew I had to pee, and the fact that I don’t really poop in public. Of course, I did what he had asked to somewhat even up the score. I think he was getting hard too. After that, he took off his gym shorts and turned around to walk into the stall, and I could finally see the load he released into his boxer briefs (I think he was wearing American Eagle, but I don’t remember, exactly). It seemed like he might have been constipated or something, as it looked fairly big to be a typical daily poop, and that was the day it was coming out (he never did say, nor did I bother asking, so I’m just guessing). Watching him limp to the stall with that giant poop in his underwear got me hard again. After we both got cleaned up, we changed into our regular clothes. I ended up going commando for the rest of the day, but because my friend runs track, he had his compression shorts as his disposal (I figured that because he was brave enough to poop himself in front me, I wouldn’t force him to go commando too). Then, we just stood by the gym doors and waited for the bell to ring. To this day, nobody we knew ever found out.
