Once in the gym, Jon lined up in his usual spot for roll call. The rest of the class, however, wasn't nearly so punctual. One by one, or in many cases two by two, they sauntered out wiping their faces, hands, or cocks with a paper towel. A trashcan was strategically placed to gather the refuse.
Other than everyone being naked, the gym class itself wasn't terribly strange. First came sprints, then a few calisthenics, then volleyball for half the class and badminton for the rest. The strange part, at least to Jon, was the way most of the boys ogled each other. It reminded Jon of the way guys usually looked at girls.
With ten minutes left in the period Mr. Flecks blew his whistle again and sent everyone to the showers. Joseph, Adam, and Jeff, and a couple of other boys all propositioned Jon but he told them all he was sore.
When the bell ran, everyone nonchalantly left the locker room stark naked. Jon stood watching them until he was alone, then followed the last boy into the hallway. Nothing, of course, could have prepared him for the scene he discovered.
Every single male, student or teacher, was naked! And every single girl or woman was clothed!
