Rarity moaned contently as a spa pony placed sliced cucumbers over her eyes before moving over to do the same to Fluttershy, who fidgeted, trying to get her wings into a comfortable position in the mud, without much luck.

“I say, Darling, it’s this luxurious? Just devine in how the mud gets into every nook and crevice of one’s body.”

“Uhm, it’s not too bad, I guess. I enjoy the, uh, color.”

“Fluttershy!” Rarity snarked, “I’ll not have such talk, this is imported from across the realm, there’s no reason to love only the color, which is quite garrish and… dark. It’s about the minerals and whatnot.”

“Yes, it’s nice and all, but I don’t like how it gets, under my tail,” she said blushing.

Rarity used her magic to lift one of the cucumbers off her eyes to glance at the blushing pegasus with a smirk.

“Say, Fluttershy… I was meaning to ask, since we’re essentially alone, how has it been?”

“Oh, well enough I suppose,” she replied finally sinking into the mud with a sigh as the weight pressed against her chest; she let her wings and forelegs sink as well into the warm embrace, “Mister Bird has a slight cough, Angel is taking care of it while we’re… I’m out, and-”

“No, no, no,” Rarity said with a haughty laugh and removal of both cucumbers, setting them aside, “I mean your relationship with Pinkie Pie! Darling, I imagine she’s quite the hoof full; what with her boundless energy and impatience. It must be terribly exhausting.”

“Oh, uhm… No, it’s actually really nice to be with her. She helps me to,” she hesitated, “relieve stress and I help her feel things she always wanted to feel but didn’t know how.”

Rarity laid back with a sly grin. “Oh, do enlighten me.”

“Uhm, well it’s just kind of pretty private, and I wouldn't want Pinkie to, well you know.”

Replacing the cucumbers she insisted again. “Fluttershy, I may be able to help if you’re having troubles, and a nice comparison couldn’t hurt. Celestia knows I’ve gotten quite a few tales of my exploits while traveling the country.

“I’ll start. There was a stallion in Manehattan that was simply perfect, save for a slight malodor that one couldn’t ignore. It didn’t stop us from having a time, or perhaps three in a broom closet before and after the fashion show. If he hadn’t surpassed me, I imagine we might have at least had dinner the same evening, but I digress; your turn, deary.”

Fluttershy blushed and gulped while beginning to breathe heavily.

“Fluttershy, are you alright?”

“Y-yes. F-f-fine. Um, when I was a filly-”

“No, Fluttershy, I mean… Oh,” she stopped and listened.

“Um, when I was a filly a couple of stallions would stay with my mother and… well, Pinkie helps me with that.”

“Oh, Fluttershy. I’m so sorry, I had no idea,” Rarity pouted and sank deeper into the mud. “Is there anything, perhaps, I can do to help you?”

Fluttershy grinned slightly. “Can you wear a collar?” she asked confidently.

“Wh-what was that?”

“Oh! N-nothing… I was just, um-”

A shout came from the other side of the spa.

Fluttershy and Rarity gasped slightly as they felt their chests obtain a warm sensation.

“Oh, certainly they’d keep riff-raff out of here. Anyway, what were you saying about a collar?” Rarity asked blushing lightly as she took the cucumbers off her eyes to look at the happy grin on Fluttershy’s blushing face. The noise had drawn the other spa ponies away, leaving them alone.

“Oh, I was, um… Do you know what a collar is?”

“Certainly I do, and,” she glanced around before leaning out of her mudpit and closer to Fluttershy, “I’ve been known to use them at times,” she whispered before fiercely meowing with a hiss after it.

Fluttershy sat up and the cucumbers on her eyes fell into the mud. “Wh-what? Y-you… too?”

“Uhm,” Rarity laid back and blushed again nodding, “on rare occasions I like to have my dates, or I, wear one with a,” she glanced around as her heart raced at the thought of telling her best friend her sexual secret, “leash. I-I don’t think we should talk about this here. Perhaps, you can come by the shop later and…”

“O-oh, maybe. Sh-should I bring my Pinkie?”

Rarity’s breathing quickened as her vision narrowed in anxiety. She nodded slightly as she sank to her chin in the mud with a whimper. “Y-yes, maybe tonight at eight, then?”

“Then, um… call me Mistress when we come by,” she finished as she gulped and got out of the mudbath, “and remember,” she looked intently at the head of the unicorn next to her, “maybes are for babies,” she finished and grabbed a towel, wrapping it around her mane before wrapping another over her back and beginning to clean herself.

“Now, meet me in the sauna so we can sweat this mud out of our fur,” Fluttershy said firmly, turning to the bathroom, wings open slightly to let the air pass by her.

Rarity gulped and trembled in nervous excitement, quickly following Fluttershy’s actions.
