I 19m work at a local school as a maintenance worker, and most of my shifts happen at night which gives me plenty of time to myself to do pretty much anything I want. Yesterday, I was doing some risky dares with a girl I met online and she told me to get fully naked in a classroom and lube a marker and fuck myself on the teachers desk which I happily did. But then after that she told me to go from class room to class room sneaking down the hallway to where the janitors are and to follow them all while I have a marker in my ass and jerking off. Eventually though after some time of me jerking me cock I had to cum and it happened wt the first possible moment. As I am about to cum in this classroom I hear the female janitor walking towards the same room that I am currently in. Having no choice but to run and hide in the back of the room where there is a table with long black cloth that I can hide under. However, as I am running I begin to cum and watch as it hits the ground and stand out on the dark hardwood floor. Eventually she walks into the room as if she definitely heard me and I squeeze my cock as hard as I can to refrain from cumming everywhere and giving up my hiding spot. She then ends up finding my trail of cum leading to the table and my heart is pounding and my cock is throbbing that it hurts. But she doesn’t end up looking under the table and insteads takes her sweet time cleaning up my cum which makes me even more horny but I end up hiding there until she leaves the room and shuts the lights off before hurrying back to my clothes and leaving as fast as I could. I can’t wait to do it all over again next week
