They both made their way to the gym locker rooms. There were only four girls lined up at the girls door.
"Hmm, seems vampires and witches don't like sunlight" thought Jon.
Ms. Knashford checked off the girls on her list as they walked into the locker room.
Jon was in the middle of the line for the boys locker room. Looking at his classmates, he got to see how they'd changed.
The jock with the ostrich body was there, and the one with the ballerina body. A couple of the nerds were now as buff as the jocks,
"They must've gone to the party as superheroes" thought Jon.
The line started to move forward as Mr. Taleigh checked the boys off on his list, but as Jon reached the door he was stopped.
"What do you think you're doing in this line Jon?" said Mr Taleigh, sternly. "Going to get changed for gym?" said Jon.
"Yeah, not in here your not, get back to the girl's room" he said, pushing Jon towards the girls locker room door.
"Wait, so they do know I'm a girl" thought Jon, walking into the girls locker room, Ms Knashford checking him off her list.
Entering the room, he saw no one was near Karyn, so he made his way over to her.
"Hey!" whispered Karyn in surprise, "You shouldn't be in here!"
"They think I'm a girl" whispered Jon. "And well, I suppose I am." he whispered, gesturing at himself.
"Well just get changed quick, you're as lucky as I am they swapped pool and track day" said Karyn
"Wait!" said Jon, surprised "they did what now?"
"You brought your trunks didn't you"
"Yep" replied Jon
"Don't worry" replied Karyn, "I have a spare set of gym clothes in my locker."
Retrieving the spare clothes for Jon, she continued to change into hers.
Jon got changed as fast as he could, the gym shorts were just that, short, and quite the close fit. Leaving nothing to the imagination, or they would have, had he had his usual equipment.
The t-shirt was also a tighter cut than he was used to, but it still left him looking flat chested.
The track session felt like it lasted forever. But it ended and they got changed back and proceeded with the rest of their days.
The rest of the day was pretty uneventful. At lunch Jon and Karyn got to see more of the altered students.
A group of jocks must've all gone to the party with rubber animal masks on, because their table looked like a farmyard. Two of them had pig heads, there was one with a bull's head, which sported rather large horns.
There were also a few others, but they couldn't make them out through the crowds.
Over in one corner was a small group of nerdy girls, they all seemed to have long cat tails, and cat ears. "Must be into some obscure anime" chuckled Jon.
The ballerina jock was on a table with his girlfriend, who now had a body like one of the members of the school football team. "Hey Karyn, reckon they had a similar bet to us?" said Jon. Karyn looked over at them and giggled.
