To strip! Strip! Strip!

In the end, it was not really a choice at all.

Mary stood up, and despite how shaky and nervous she'd felt before suddenly felt normal again. Perhaps making the decision had made it easier to accept. She turned her back to the classroom and began to fumble with her shirt buttons. Her hands did not agree to her decision, it seemed. Once she had the buttons undone, she pulled the shirt open and eased it past her shoulders. There was a cheer of approval as she handed the garment to Miss Bramski. With her back to the room, she felt emboldened to go for the bra next. Her hands reached up behind her but were even less willing to comply with her now. After a few moments of fumbling, Miss Bramski stepped up and offered to help. Between them they unhooked her bra, eased the straps down her arm and, just like that, Mary found herself topless in her Sociology Class. The other students cheered again, and one of the boys called for her to turn around. She ignored him.

Next, Mary reached for the fastener on her skirt... then stopped. Her knickers were unflattering today; she'd opted for her nan knickers. Best to take them off first. She reached underneath her skirt, hooked her fingers into the waistline of her knickers and pulled them down to her knees. Gravity did the rest, and as she stepped out of them Miss Bramski stooped to pick them up and put them with the rest of her clothing in one of her drawers. There was only one thing left. Closing her eyes, Mary reached for the fastener once again but this time unclipped it. The zip lowering sounded like thunder in her ears. It reached the bottom, and before Mary could stop it the material flopped onto the floor. She heard the 'swish' sound as Miss Bramski picked it up.

"It's a full moon tonight!" the turn-around boy called out.

Mary opened her eyes, and looked down. She felt an odd mixture of panic, horror, and... arousal? She took a moment to position her arm across her enormous breasts and a hand over her crotch, just like Emma had, and then turned to face the class. She kept her eyes firmly on the ground, though. She couldn't bear to look at them.

"Okay then," Miss Bramski said. "I'll bring the two girls back out now, but before I do... we can convince them that it's a lottery situation, where only a few students are required to be naked. But it would help enforce the fiction of a National Nude Day if there were others naked, too. We're not forcing this on anyone, but if we have any volunteers it might make Emma and Jenny's day a little easier if anyone else was naked."
