The saleswoman barges into the changing room

Yuki had just been picking up a pair of shorts when she was interrupted. Two quick knocks were followed (with barely a half-second pause) by the door to the small room bursting open.

"Hey there!" the woman from earlier said as Yuki awkwardly moved the shorts in front of her underwear. "I figured you might want to try out some things from our athletic line, too!" She held up a few black and gray garments.

"I-I'm kind of getting changed!" Yuki blurted out, embarrassed but also still utterly surprised that an employee would barge into an occupied room like that.

"Oh don't worry dear, I don't mind at all!" the woman said cheerfully, as if that settled the matter. "Say," she said, her eyes honing in on Yuki's chest, "you have GOT to try one of our sports bras! I speak from experience when I say they're the most comfortable ones I've ever worn!" The employee set the rest of the athletic clothes on top of the pile of clothing before thrusting a folded up sports bra towards Yuki.

"Uh, sure, fine," Yuki said, snatching the bra and using it to partially shield the bra she was wearing. "Can you just leave?!"

"Oh, sure! I'll just leave you to it, then!" she said with a smile before zipping out of the room. Yuki immediately slammed the door shut behind her. Much to her dismay, it seemed like there was no locking mechanism on the door whatsoever.

"Some people..." Yuki mumbled, letting her embarrassment slowly dissipate. She set the sports bra on top of her sundress and began sliding the shorts up her legs. They fit wonderfully, much to her delight, framing her bubble butt quite a charming way. And the fabric felt... interesting. The beige shorts felt softer than most she was used to. And, interestingly enough, there was no fly or button on them. Instead the waistband of the shorts seemed to be able to be stretched slightly. Yuki experimented and tried stretching out the rest of the shorts, and found that the entire garment had a reasonable amount of flexibility to it. "What is this stuff?" she mused to herself.

Next, Yuki had been planning to try on a black tank top she'd selected, but the sports bra the saleswoman had been so adamant about caught her eye. Yuki didn't exactly need a new sports bra, but what was the harm in trying one on? She shrugged before unclasping her bra and shrugging out of it. She pulled the black and gray bra over her head and adjusted it until it was in place. And, Yuki had to admit, it was quite comfy. She jumped in place a few times, testing the bra out, and found it did a fantastic job of keeping her girls in place.

Damn, she thought, I might actually end up buying this too!

With any thoughts of the overbearing saleswoman banished from her mind, Yuki eyed the pile of clothes, deciding what to try on next.
