It's quite revealing

"Okay!" Sharon said as she shut the fitting room door. "Go ahead and take off your top and we'll get started. Don't be shy, I'm a professional. Oh!" she said upon noticing that Mackenzie was wearing a dress. "I mean your dress, sorry."

Mackenzie began peeling off her sundress, unable to keep a slight blush off her face. Even if it was for a professional, she was voluntarily undressing in front of a stranger! The redhead folded the yellow fabric up and placed it on the small bench beside the mirror. Sharon pulled out a tape measure and began looking over Mackenzie's pink bra.

"Hmm... oh dear no. This is completely the wrong size for you. I can tell." she said. "We won't get accurate measurements with this in the way!

"Are you sure?" Mackenzie asked, though she had to admit the garment wasn't as comfortable as it had been when she first bought it.

"Absolutely! Go ahead and remove it and I'll start measuring your chest."

Mackenzie nervously reached behind her back and unclasped her bra. She slowly pulled the garment off her body, baring her breasts to the woman in front of her. Her nipples stiffened slightly as they were exposed to the open air of the fitting room, and Mackenzie awkwardly looked herself over in the mirror. She fought the urge to cover her boobs as Sharon began draping the measuring tape around her torso.

"See? Nothing to be embarrassed about. Now let's see... 36 for the chest size. And now..." she readjusted the tape, draping it right over Mackenzie's nipples. Mackenzie shivered slightly at the sensation but didn't say anything. "Aaaaand 40 for the bust size. So let's try fitting you with a 36D to start, my dear."

"Wait, 36D?" Mackenzie asked. "But I've been wearing a 36C for-"

"What did I tell you?" Sharon interrupted merrily. "You've been wearing the wrong size and you didn't even know it!"

"Huh. I guess so..." Mackenzie said, recalling how her bras hadn't quite been fitting as nicely as they once did. She began reaching for the bra she had taken off earlier.

"Oh, you might as well leave that off. I'll be right back with a bra for you to try on." Sharon said before eyeing the matching pink panties on Mackenzie's hips. "Oh, and while we're at it do you need any new panties?"

"Oh, no I'm fine on that front." Mackenzie said, still fighting the urge to cover her chest.

"Hmm..." Without another word, Sharon slid a finger into the side of Mackenzie's panties and stretched them out from her hip. Mackenzie stifled a cry as the strange woman began fiddling with the only thing she was left wearing. "Oh no, my dear. These are far too old. Just look how far the waistband stretches!"

"I-it's fine!" Mackenzie said, anxiously.

"Nonsense! Let me get a hip measurement for you." Before Mackenzie could say another word, Sharon looped the tape measure around Mackenzie's hips. "I'll just get these out of the way." she said as she slid Mackenzie's panties down her hips a few inches. Mackenzie let out a small embarrassed squeak as she felt the hands undressing her slightly.

"No need to be nervous! Just us girls in here." Sharon said as she moved the tape to where the waistband had just been. Then, after a few seconds, the panties began sliding further down Mackenzie's legs, quickly hitting the point of return and falling down to her ankles. Mackenzie's eyes went wide as she suddenly saw her bare pussy, clear as day in the mirror before her. She was standing there naked!

"Oh, whoops!" Sharon said, "See, if you were wearing properly fitting ones that wouldn't have happened. Looks like 36 for the hips size. Okay! I'll be right back with some underwear for you to try on. Don't go anywhere!"

Sharon laughed heartily at her own joke as she stepped out of the fitting room. Mackenzie stepped over and hastily pulled the door shut before anyone could see nude body. After a few moments, the redhead picked up her panties and set them on top of her bra and dress. Then, with nothing else to do, Mackenzie began looking at herself in the mirror. She cupped a breast in each hand and gave them a tentative bounce. Maybe they had gotten bigger since she last shopped for underwear. Perhaps she'd be better off buying several new sets anyway. And maybe even something sexy to wear for Ryan.

Mackenzie lightly bit her lip as she thought about her boyfriend and the next time she'd be able to see him. That was when the naked girl started to notice just how many noises she could hear coming from outside the fitting room. Mackenzie soon became fully aware that she was in the middle of a crowded mall, stark naked, with just these four flimsy walls separating her from humiliation. She felt her heart begin to race again as the scenario sent a familiar tingle of arousal through her body. Something about being this close to exposure, but still somehow safe, was what really did it for Mackenzie. Without even realizing it, one of her hands had made its way up to her breast, and was playfully flicking at her nipple. And her other was sliding down towards her womanhood.

What am I doing? Mackenzie thought to herself as she withdrew her hands. Sharon could be back any second now! I can't... be doing THIS right now.

The redhead shook her head back and forth a few times, trying to forget that train of thought. Then Mackenzie continued standing there, still naked from head to toe.
