I went to one of the standalone unisex bathrooms to coom in private and a teacher walked in on me even though I thought I’d locked the door.

I dunno if the lock was broken or what but it was right at the point where I coomed. I covered up as quick as I could but I think she could figure out that I was jerking off.

I feel so embarrassed. Should I worry about her telling someone? Is there a rule against it?
