"Hi everyone, I'm Emily, welcome to the Theater club! We're glad you could all join us. First let's go around and have everyone say their name." As everyone was going around the circle introducing themselves one by one, Mackenzie sighed in relief as she didn't recognize anyone who showed up. Hopefully this meant that she could make a good first impression on them without the stigma of the Shy Streaker over her head.

"Great, now that everyone's done introducing themselves, we're going to do a fun little ice breaker. I'd like everyone to go backstage and pick out a costume, put it on, and come back to me on stage." With that, the group of about 20 or so students went back stage and began rummaging through the chest full of costumes. Mackenzie ended up last in line, and as everyone began pulling their chosen costumes over their clothes, and headed back out to the main stage, Mackenzie was left with just a tutu at the bottom of the chest. Mackenzie quickly tried to pull the tutu over her clothes but realized that the tutu was made for someone much smaller and much less endowed than she was. By this point, almost everyone had gotten their costumes on and had left the backstage area, leaving Mackenzie to panic.

"Anyone left in there?" Emily called out.

"Just a minute!" Mackenzie replied shakily.

Shit, what am I gonna do. Mackenzie really didn't want to make a bad impression on a new group of people, but there was no way she was getting the tutu on over her clothes. As a last resort Mackenzie quickly whipped off her shorts, and shirt, leaving her there naked, as she had been out of underwear ever since the scavenger hunt incident.

"Need any help in he.." Mackenzie turned her head to see Emily as she opened the curtain, with her ass pointed directly at her as she was beginning to pull on the tutu.

"Oh, um, never mind," Emily said turning to go back to the group.

Well Great. At least it was just Emily. Mackenzie eventually hiked up the tutu and headed to the stage back to the circle where the rest of the group waited for her. Mackenzie sheepishly made her way across stage, not because of what had just happened between her and Emily, but because the tutu was showing off way more than Mackenzie was comfortable with. Her large breasts were straining against the top of the tutu, but she was unable to adjust without showing off more of her ass, which was already peaking through under her skirt. Without underwear, it was certainly a sight, one that the boys in the group took in a little too closely.

"Great, glad you could join us Mackenzie, I was just explaining to everyone the improv exercise we were about to do. Since everyone picked out a costume, I thought it would be fun to have everyone act out a little scene as the character the costume they wore associates with. For example, I'm dressed as a pirate." Emily proceeds to act like a pirate for about 30 seconds before giving a curtsey to some light applause. "Alright, why don't you go next Mackenzie?"

"Um, sure." Mackenzie, like her unwanted alter ego the Shy Streaker would suggest, was a little shy, but this was something new, there was nothing to be embarrassed about. So Mackenzie decided, as she was dressed like a ballerina, to do some ballet moves. Mackenzie started a bit stiff but eventually got carried away in her act, trying her best to mimic the delicate, and graceful moves of a ballerina, but although Mackenzie had an athletic body, she wasn't the most agile. Mackenzie decided to finish her act with a spin, but in doing so, got her feet tangled up with each other, and she ended up falling face down, with her back to the group.

"Holy shit!"

Mackenzie turned back to see the shocked faces of the other students, before remembering her state of dress, realizing everyone had just gotten an up skirt view of her shaved pussy and ass. Mackenzie quickly got up, pulling the tutu down to cover her bottom, but in doing so, she pulled a little too far down, leaving her boobs in view for a few seconds before realizing. Mackenzie, red in the face, adjusted again, covering herself as she had before, and sheepishly gave a curtsey of her own. The group stood in silence before one of the boys began clapping enthusiastically, to which the rest of the group broke out of the trance and followed along.

"Uh, thanks Mackenzie, that was a great." Emily said before quickly prompting the next person to begin their act. Thankfully for Mackenzie there was little interest for the rest of the meeting before it ended.

"Alright everyone, I really enjoyed meeting you all, I'll see everyone at the next meeting. Don't forget to put your costume back!" Mackenzie waited for everyone to finish changing and leave before she began to undress for obvious reasons, but as she was doing so, she realized her clothes were missing. How does this keep happening!? Exasperated, Mackenzie knew she couldn't keep the tutu, as there was no way anyone would forget it was the costume she had worn, and not wanting to be kicked out of the club for stealing, Mackenzie eventually stripped, and made yet another nude dash back to her dorm.
