There's a thread over at Reddit of people describing getting caught masturbating. Just in case you're still finding it too easy to study and need some more quality procrastinating, here's the link.
A sample from the person that started the thread:
A few weeks ago, I had some alone time and was strategically using it to my advantage. It was early on a Saturday morning and no one was around. sitting on my bed, laptop beside me, I put on my headphones and began to performing articificial sex on my phallus.
Progress at close to 90%, I began to get "in the Zone" and failed to hear a person knocking on my door. I was so entranced in fact, that I didn't even break my concentration when the door began to open and on of my lady friends burst into the room with Dunkin' Doughnuts in hand. She then supposedly sat down in a chair and just started whistling. About thirty seconds later my "alone time" came to fruition, sexually satisfied noises and everything.
Taking my headphones off and turning my attention away from the laptop. I heard a voice say "That was entertaining." I then said, "Well, this is awkward..." to which she replied, "It's only awkward if you make it awkward." She then promptly stood up, and promptly left..
This interaction was never spoken of again.
That was my story, Reddit, what is your best caught masturbating story?
