The cloud of flour that had filled the room was starting to settle down and Spike could finally see the outlines of the other two ponies on the other side of the room. He started moving towards them, and so did Pinkie judging by the sound of hooves splashing behind him.

They were staring at something behind him. He walked up next to them, and turned around to see Pinkie Pie following closely, still covered in flour. The room behind her was a complete mess. The large pool of bodily fluids covered almost the entire floor, and there was flour absolutely everywhere. At the back of the room lay the sorry remains of the flour sacks, and soaking in the puddle on the floor was the wooden board that had been part of the peculiar bucking device. Pinkie Pie joined them, and turned towards the flour sacks as well.

For a moment, Spike wondered what was going on. He could see they all had weird smiles on their faces. Finally, Pinkie Pie’s smile started quivering and she burst out laughing. The other two could no longer contain themselves, and burst into laughter as well. Spike could see the humor of the situation, and with the three ponies laughing hysterically next to him, he soon burst into laughter as well.

For several minutes, they rolled on the floor laughing, until their sides ached. When the laughter subsided, Luna stood up, a wide smile on her face, and said in a quivering voice “Oh my sister! I have seen many things in my lifetime, but never before have I beheld such an unholy mess!”.

Spike was surprised at how ordinary she sounded when not using the Traditional Royal Canterlot Voice, or speaking in the Royal We. Apart from the noble and slightly unusual way the spoke, she sounded much like any other pony. Apparently she had been practicing since her last appearance in Ponyville.

“I know, right!” said Pinkie Pie, tears of laughter in her eyes, as she got up.

Fluttershy said nothing, but was looking at Spike and smiling sweetly, her wet mane hanging down and dripping onto the floor.
As he looked towards her, their eyes connected.
He felt himself starting to blush, and quickly turned away.
This, when he thought about it, was a bit weird, considering that less than an hour ago, she had been riding him in a frenzy of lust, using him as a living dildo.

Pinkie Pie opened the door, revealing a hallway outside the room, and disappeared into one of several side rooms in the hallway, returning shortly thereafter with a garden hose.
All the ponies started to take off their leather suits, revealing the wet messy fur underneath, and began to hose each other down, washing away the worst of the flour and urine residue from their coats. When they were done, Pinkie Pie gave Spike a hosedown as well.

“Come on!” said Pinkie Pie cheerfully, and signaled for Spike to follow her.

He followed the three ponies, still dripping wet, through the hallway and up the stairs, all the way up to Pinkie’s penthouse.

“What we need now is a nice hot bath!” proclaimed Pinkie Pie, as she started to draw a bath.
While the tub was filling up, she darted out of the room, disappearing for a short while, before returning with a bucket of ice cubes containing a bottle of wine and four glasses.

She climbed into the tub, and looking at the others, said “Hop in!”.

It was a bit cramped, but somehow all three ponies managed to get in the tub, and sat down with their backs against the wall, with Luna on the left, Pinkie Pie in the middle, and Fluttershy on the right. Spike climbed in, and seated himself against the front wall of the tub, facing them. He felt the wonderful warmth of the bath water spread through his body, rapidly counteracting the coldness of the hose water.

Pinkie Pie poured them each a glass of wine, and spoke again. “I’m sure you have many questions, Spike, but first I must say this.”
After a brief pause, stretching her front hooves up in the air and spilling a little wine into the tub, she continued “Welcome to the Ponyville S&M Club!”

Spike did indeed have many questions, but wasn’t quite sure where to start.
He took a sip from his wine glass. “So, this is wine.” he thought. “Tastes like crap, but if the others drink it, so will I...” his mind went on.

“So...” he began. “This S&M club... is it just the three of you?”

Pinkie Pie quickly answered “Actually, Luna here” she indicated Luna with her hoof “isn’t a member of our club. She has her own S&M club in Canterlot, and only occasionally comes to visit us down here.”

Luna herself interjected “I especially chose to come down here today out of curiousity. We have never had a dragon attend our parties in Canterlot.”. “Especially not one as well-endowed as yourself.” she continued, giving him a flirty wink.

Pinkie Pie spoke again “We do have a few other members though.”.
“There’s Bon Bon, who used to come here a lot. She hasn’t been attending as often since she started dating that unicorn musician Lyra, though.” she went on.
“I hear Lyra is also into watersports.” she added, grinning.

“Watersports?” Spike asked.

“Urinating during sex.” answered Fluttershy, and then, realizing everyone was looking at her, continued “Um... I mean...”. She started blushing and slowly lowering her head into the water.

The others chuckled, turning back to Spike.

“Yes, what she said.” confirmed Luna.

“Oh, and there’s Big Macintosh” continued Pinkie Pie. “He used to come here all the time, but he hasn’t been attending as frequently lately. Not since he got injured in the accident.”
She squinted her eyes, and looking at Spike conspiratorially, added in a lowered voice “... and you didn’t hear this from me, but I’ve heard rumors he’s got it going on with his sister Applejack.”

Spike choked on his wine, spraying it all over Pinkie Pie’s face. “Big Mac and Applejack!?” he repeated, almost not believing his own ears.

“Sssh. Not so loud.” said Pinkie Pie, and dipped her face in the water to wash away the wine.
The other two ponies chuckled at his outburst. “We don’t want the entire town to know, do we?” she continued, her face and mane dripping with water.

“Then there’s Golden Harvest.” said Pinkie.

“Who?” Spike wondered.

“You may not have spoken to her before. She’s a yellow earth pony with a curly orange mane, and three carrots for a cutie mark.” Pinkie went on.

Spike instantly recognized the description. “Oh, yeah, I’ve seen her around. So that’s her name...”.

“Anyway, she has a bit unusual tastes. She likes to use a carrot as a dildo!” Pinkie continued, then added “She couldn’t attend today. Her loss!”

Spike found it rather ironic that Pinkie would accuse anyone else of having unusual tastes after what they’d just been through, but didn’t say anything.

“And then there’s that mysterious brown stallion with the hourglass cutie mark who refuses to tell his name. He calls himself ‘The Doctor’.” Pinkie resumed. “He’s not officially a member, but he once appeared in a strange box-shaped thingy during one of our get-togethers.” she went on. “Said it was an accident, but he seemed to enjoy himself, and has continued to occasionally show up since. We don’t mind, as it’s much more fun with a male present!”

“...and that’s why you invited me?” asked Spike.

“Yes! Fluttershy said she heard a rumor that you were VERY well-endowed. Which turned out to be true!” replied Pinkie.

Fluttershy blushed again, and tried to hide her face in the water.

“I have to ask... why all the shenanigans? Drugging me with a cupcake, chaining me up, and wearing those ridiculous suits?” Spike asked. “You could have just asked me.” he added.

“Oh, silly, where’s the fun in that? We just had to give you a bit of a scare!” Pinkie answered, giggling.
“We don’t always wear the suits, but when using the whip, they prevent it from leaving scars.” she added in a more serious tone.

Spike thought about this, and decided not to inquire deeper into the matter.
“What about you?” he asked, turning to look at Fluttershy. “What was the deal with that personality change of yours?” he continued.

Pinkie Pie opened her mouth to answer, but was cut off by Fluttershy herself. “Um... I don’t really know. It just happens sometimes, when I get very excited.” she said, blushing. “Especially... um... well... especially when I see...” she paused, blushing even more deeply, before continuing “...blood.”.

“So, you get excited when you feel pain and see blood?” Spike summarized.

She nodded, lowering her face into the water again, obviously deeply ashamed of herself, her breath creating bubbles in the water.

Spike didn’t want to make her feel any more uncomfortable, and turned to Luna instead.
“How were you able to pee for so long?” he asked her.

“It is something that comes with being royalty. With our busy schedules, toilet breaks can be few and far between.” she answered. “As for the force, that is practice.” she added, smiling.

“So, your sister can do that too?” he wondered, suddenly thinking about Celestia.

“She has had a thousand years of practice, even when I was imprisoned in the moon. Her bladder would likely be even bigger than mine.” Luna replied.

“What about that strange machine you chained me to?” he asked.

“Do not look at me. That was Pinkie Pie’s idea.” replied Luna, throwing an accusing glance over at Pinkie Pie.

“It was just something I whipped up in my spare time!” Pinkie continued.
“It seemed like a good idea at the time!” she shrugged, adding “It would have worked too, if that dumb board hadn’t come loose.”

Spike sighed. It was just like Pinkie Pie to come up with something crazy like that.
He turned to Fluttershy, who by now had resurfaced from the water.
“Why did you say all those mean things to Pinkie Pie when she was tied up?” he asked her.

The answer came from Pinkie Pie instead “I’ll explain that!”. “Remember last year, when I forgot about my own birthday, thought my friends didn’t like me anymore and had a mental breakdown?”

Spike nodded. He remembered all too well how she had tempted him with a bowl of delicious gems and forced him to lie in order to get them.

“Well, that got me curious, so me and Fluttershy did a bit of experimenting.” Pinkie went on. “And by some concentration on my part, and a lot of practicing for her to be as nasty as possible to me, we were able to reproduce it!”

“And it gets better...” she continued. “When she finally got me off, I had the bestest most incredible orgasm ever!”
She stretched her hooves out excitedly to indicate the greatness of the orgasm, beaming at him.
Fluttershy was blushing and trying to submerge her face again.

“You’re crazy, you know that?” Spike said to Pinkie Pie, rolling his eyes.

“I may be crazy, but I get to have the best orgasms ever!” she replied, grinning widely at him before taking a big sip from her wine glass.

“So... about the S&M club... am I a member now?” he asked.

“If you want to!” replied Pinkie, and adding “It’s so hard to find reliable male members!”.
“I’ll let you know whenever we’re getting together!” she continued.

“Does that mean I have to get whipped?” he asked nervously.

“Not if you don’t want to!” she replied. “I’ll get you a leather suit too, and you can whip us, kick us and call us nasty things while ramming your dong in our plotholes!”

“And ride us!” Fluttershy interjected excitedly, then blushed upon noticing that everyone was looking at her.

“Yes, that too!” Pinkie continued. “We do have some special saddles as well!”

Spike was intrigued by the thought of this. He’d never thought about riding a pony as anything sexual. He rode on Twilight’s back all the time, and she didn’t even wear a saddle. Nevertheless, the thought of riding Fluttershy was turning him on.

He grinned. “I’ll do it!”

Time passed quickly, as they continued to chat about the S&M club, their friends and the recent goings-on in Ponyville while enjoying the warmth of the water, and the wine was starting to affect them all a little.

A sudden yelp from Pinkie Pie broke their conversation, and the head of a small cute alligator surfaced over her crotch, staring blankly into the air. “Oooh, itsh jusht Gummy.” she slurred. “I peed a little!”

“Speaking of that, we require relieving of the bladder ash well.” Luna interjected, a slight hint of drunken slur in her voice.

“Um... I have to pee as well.” Fluttershy said.

“I know! Let’sh make it a contesht!” suggested Pinkie Pie. “We pee underwater, and whoever createsh the longesht jet winsh!”. “Shpike will be the judge!” she added.

“Ash if you mere mortalsh could posshibly beat ush!” laughed Luna.

“Hey, that’sh mortalisht!” Pinkie Pie retorted.

“Whatever! Let’sh do it!” replied Luna.

“Fluttershy will go firsht! Ready Shpike?” said Pinkie Pie.

Spike sighed and dove under, and after his vision became accustomed to the water, stuck a hand up to signal that he was ready. He could see Fluttershy spreading her legs a little, as a yellow jet erupted from the slit between her flanks and started to dissapate into the water. It went on for a while, before slowing down and finally stopping. He surfaced to get his breath back.

“It’sh my turn now!” said Pinkie Pie.

Spike dove down again and fixed his eyes on Pinkie Pie’s crotch as she spread her legs and started producing a yellow jet. It was darker in color than Fluttershy’s but slightly shorter. The bathwater was beginning to take on a slight yellow hue. After she finished, he surfaced again.

“That’sh nothing! We will show you how it’sh done!” said Luna.

He dove down once again, staring at Luna’s slit as she prepared herself.
At first, she produced a normal jet similar to Fluttershy’s, but as she pushed harder it grew to an enormous size and length, engulfing Spike and pushing him back against the wall of the tub.
She went on much longer than the other two, and there was little doubt as to who the winner was.

He surfaced again, to see that the bathwater had turned almost completely yellow.

“So, who’sh the winner?” Pinkie Pie inquired.

“Luna. No doubt about it.” he replied.

Luna celebrated the victory with a hoof pump, until a mildly annoyed Pinkie Pie prodded her flank.

Suddenly, Spike remembered that he was probably supposed to have been home a long time ago. “Hey, guysh! What time ish it?” he asked.

They either didn’t hear him, or ignored him, as they were too busy trying to prod each other in the most sensitive areas possible. The sight would have aroused him, but his balls already ached from having too many orgasms before. He sighed, and climbed out of the yellow water. He found a towel in a nearby cupboard, wiped himself dry, and headed downstairs towards the exit.

When he finally reached the library, he found Twilight waiting for him. He wasn’t surprised.

“Spike, where have you been all day?” she asked in a worried, slightly annoyed voice.
“It’s well past midnight!” she added.

He was tired, and wasn’t in the mood to argue with her at this point.
Explainations could wait until tomorrow, and in any case, he had to come up with one he could actually tell her first.
“Yesh mom!” he replied sarcastically, and walked past her.

“Spike, are you drunk?” she inquired.

He ignored her, and continued up the stairs to his basket, where he threw himself down and fell asleep almost instantly.

Twilight came up shortly after, and pulled a warm blanket over him.
“Good night, Spike.” she said quietly, before climbing into her own bed.
