Reading a story on creaming in my underwear reminded me of a Mechanical Drawing Exam some 50 years ago. I don't recall what we were drawing, or even that it was of an erotic shape, but under the pressure of the clock.
My system apparently went into overdrive. I soon felt this wetness in my pants, but both hands were on the drawing board, honest. Fortunately, I was wearing dark jeans; so, the wetness didn't show through. I don't remember either, what I got on the exam.
