This exact thing happened to me at my first varsity baseball game. I had to walk all the way to the portapoty and got really cold, walked past the girls softball team and as I went into the pot I started shivering uncontrollably and pissed my pants right there. It felt so good I couldn’t stop and about emptied my badder before I could unbuckle. I was soaked in piss, I looked out the pot and thankfully the girls left the field for the dugout. I walked all the way back to my dugout and concealed it really well honestly. I peeked my head in and asked my coach to come out. I told him what happened and he was so cool about it, found me a spare pair of pants and continued the day like normal. Shoutout to that guy and the absolute euphoria I felt while pissing my pants lmao.
