“I choose transform” Jen whispered.
Sam began. “You have the ability to completely conceal yourself. This also affects anyone you touch or anything you’re holding.”
Just as she finished, they heard the deadbolt release. Sam quickly shoved their backpacks into her hands then held onto Jen’s arm. Jen tested her new ability as the door creaked open. The principal walked in with the janitor close behind.
“Who’s in here.” He said, surveying the room and noticing Sam’s panties on the floor.
Sam and Jen were practically holding their breath as they watched him pick them up. He repeated himself to the seemingly empty room then tucked Sam’s panties into a pocket on his suit jacket.
“I’m not going to ask again.”
Jen’s ability had worked. He was completely oblivious to the two of them standing only a few feet to his right. He pushed open the stall doors, but found each one as empty as the last.
“Must have been some prank... How do you suppose they managed to lock it from the outside?"
The janitor shrugged and guessed that someone managed to pick the lock. The two of them left the room, disappointed to have found the room empty.
Sam let go of Jen, then realized that she could no longer see her. “Oh shit... It works against me too.”
“What?” Jen asked.
“I can’t see you at all.” Sam replied.
Jen reappeared.
“I can’t believe that works so well...” Sam marveled.
“I’m impressed too, but we’d better get the hell out of here before someone else shows up.” Jen urged.

Thinking about her underwear made her remember the penis that hung below. In the excitement, it had gone limp and shrunk partway back into her pussy. It still felt unusual against her labia and thighs, but she didn’t have a chance look before Jen pulled her towards the door.
“I’ll buy you new ones... Lets go!” Jen insisted, pushing one of the backpacks into Sam’s hands.
“Wait... You’d better go invisible again.” Sam suggested, laying a hand on her shoulder.
“I planned on it...” With a thought, Jen placed them both under her cloak and pulled the door open...
