During the end term exams of my ninth class, the teacher was checking everyone's pocket for chits. Well that day I had come to school without any underwear and to make matters worse, this thought also gave me a hard on. The teacher reached my seat and due to my suspicious behaviour decided to check my pockets thoroughly and put a hand in my pocket. Guess what, the teacher felt my hard-on through the thin material of my pocket for a few seconds before realizing what it was.
And yes the teacher was a SHE. I looked at her and she had almost become red with embarrassment.
Well not for me but definitely for her it was one of the most embarrassing moment of her life and never again did she check any pocket in the future.
