Karyn caught up to Jon on the way to school.
"Hey Jon!" she said as she ran up to him.
"Hey Karyn, am I ever happy to see you! Did you bring the stone?" Jon asked.
Karyn said "No, I left it at home, to be safe, but I have a plan."
Jon replied "What? Oh man, what are we going to do?"
"Don't worry - is there somewhere in the guy's change room where you won't be seen by the other guys?" she asked.
"Yeah, I can go into one of the toilets, but there's not room to change in there." Jon replied.
"No problem. I'll find you in the guy's locker room." she said.
"What? How?" Jon asked, but they had arrived at school and had to go to their separate classes.
Karyn pretended to be sick in her homeroom class, and asked to go to the nurse's office. As soon as she was out of the classroom, she ran to the closest girl's bathroom. She pulled on the ring, and turned invisible. She took off her clothes, so she couldn't be seen at all. Suddenly, she realized that she needed to stash her clothes somewhere. She pulled the garbage bag out of the garbage, and stuck her clothes in the bottom of the bin, then put the garbage bag back in. She threw a couple of paper towels in to hide the lump at the bottom. Perfect!
Then she slipped out of the washroom and ran straight to the boy's locker room. Jon would be heading there right after his teacher took attendance, and she needed to get there first so she could help him. Running through the halls, completely naked, was strangely erotic for Karyn. Even though she knew that nobody could see her, she found herself getting really turned on.
Karyn got to the locker room just as the boys were getting there. She saw Jon near the back of the group, so she ran up behind him and whispered "Jon, I'm right behind you!" into his ear.
Jon jumped in surprise, and bumped into Karyn, nearly knocking her over. She giggled, and a couple of the other boys looked around. Seeing only Jon, they laughed to each other and kept on walking.
"Just keep going, I'm invisible" said Karyn. Jon relaxed a bit, and Karyn followed him into the locker room.
Karyn whispered "Let's go to one of the toilets, so I can get you fixed up".
