Dirty Little Boys Love to Play 3

I was in third grade and our classroom was just around the corner from the boys restroom. One day I had to go to the bathroom so I politely raised my hand to be excused. I went into the restroom and sat on one of the toilets. There were no partitions in this toilet so privacy was hard to come by. I had finished doing my duty when Mr. Green walked in. Mr. Green was in his 50s, about 5'10", and balding. The hair he had left was graying and combed straight back from his forehead. He had steely blue eyes that sparkled when he looked at you. Not exactly handsome, he was a good looking man with just a hint of a paunch.
