When I was a junior in college, I had to spend one of the breaks on campus because of my job at the time. If you have been to college you know that on breaks there are very few students, my dorm was a couple hundred students and there were probably 10 or less in the whole dorm during break.
On the Wednesday night I was taking a shower and I was in there for a while, just one of those things where it feels good and you don’t want to get out. I was feeling relaxed and even though it was a public shower, it had curtains that separated the shower heads so I decided to masturbate. I was very horny, for some reason I had cum in probably a week. I was just doing my thing when I heard someone come in. It startled me. I had that instant stomach ache you get when you think you just got caught in something. I was moaning and my stroking was making noise, and I was almost certain this person had heard me. I was pretty sure they were in the room for a bit before I knew they were there.
