How could they not? (They're a club)

As Anna came down from her high, she eventually caught her breath, and glanced around her. There was a lot less steam now, many of the shower heads seemed to be off. All of them besides her own. That was when Anna realized, there were still a bunch of naked girls all around her. Only, she was seeing the front of their intimates, rather than their backside.

Anna's face began to redden, as she slowly looked up and saw all of the girls staring at her. A few looked very embarrassed, some confused, some baffled, and a one of them even seemed impressed. Reality sunk in. Anna had just masturbated in front of all these girls, and they knew she did it.

"I... um... didn't think you would notice?" Anna gave a weak explanation.

The girl who looked impressed smirked, and lent a hand to Anna to help her stand. "You have no idea how lucky you are. You did that in front of us. Anybody else would have gotten you in serious trouble."

Anna blinked twice as she took the girls hand. She stood up, and placed an arm over her breasts and another over her womanhood. "I'm sorry, what?"

"We're... sort of a club, a secret club." the girl explained. "My name's Sarah," she started. "And this whole club is for girls who are into keeping their clothes off. It's an exhibitionist club." She said, moving her hair out of her face.

"Exhibitionist?" Anna repeated. "I'm sorry, um, my name's Anna, nice to meet you?" She said, feeling her heart race as all eyes were on her naked form.

"Basically we like getting naked and getting off!" Sarah explained. "Think you might be interested in joining? You were brave enough to do that in front of us, I'm sure you'd love it!" Sarah seemed genuinely comfortable being naked around all the other girls, a stark contrast from Anna.

Anna blushed fiercely. "I sort of meant to um... finish... before you all got here..."

"Oh you poor thing, you wanted privacy like Kelly?" Sarah said, gesturing towards the shy girl who was in the corner, covering herself more tightly than Anna was. "Well you know, if you want privacy, we're pretty well organized about how to find it," Sarah said, putting an arm over Anna's naked shoulder, and leading her towards the exit of the shower.

"U-um, what are you doing?" Anna asked with a shaky voice.

"I have a folder I want you to see," Sarah stated, looking back at the other girls, seeing a meek, yet pleading look on Kelly's face. "Kelly's new, give her a little space everyone. We'll show Anna what we're all about in the locker room."

The rest of the naked girls, aside from Kelly, all followed Sarah and Anna out of the shower room and into the main area of the locker room, none of them bothering with the towel rack. Anna felt very aware of her nudity and that she was being looked at by all the other girls. Even though she just had an amazing orgasm, she could still feel her heart pumping.

Sarah opened up a locker and reached inside her bag for a red folder.
