caught cumming in online class

I had a habit of jerking off during online classes every other day and I got pretty good at hiding it even though we had to have our cameras on. I would have a porn vid on the screen and jerked it under my desk without moving my shoulder in a way that aroused no suspicions. My cock points upwards so I really have to push it down under my desk and I had no trouble doing so for the past weeks. Most times I just point my cock to the downwards and ejaculate on the floor without making an orgasm face. Something about jerking in front of everyone without them knowing it was thrilling and turned me on. However, one day as I was edging for about two hours before morning class I felt cum rising up my shaft and wrapped my dick with two hands to stabilize myself. Close call. I give it a few more strokes over the head and I let out a moan as I felt my semen rise up even higher than before. Just as I think I'm in the clear I let go of my cock. Right as I let go my taint unexpectedly squeezes and I've reached the point of no return. It was too late.. I was ejaculating. I couldn't help but make an orgasm face. My cock sprung back into its upwards position, flinging semen all over my shirt, hair, stupid face, and the wall behind me. Twelve or so spurts of hot white cum appeared across the screens of my teacher and class of 32 students. I quickly left the zoom meeting and never came back. One of the most legendary cumshots in my life just happened and the load shot higher than ever before. I guess the thrill of jerking off in class made me shoot especially hard. Thankfully this was just two days before I graduated so I didn't have to face much backlash. Fuck... it felt so good so no regrets haha
