Friendship is Gambling

The sun was setting in the far off distance. Rainbow looked onwards with a tear still sliding down her cheek. It had been roughly an hour since she woke up, and the poor mare was still unable to obtain much more sleep. Still, she got enough to consider herself well rested, but her mistress, Luna, had almost squeezed the life out of her during their slumbers.

Rainbow thought about the race, and how she had been previously bested by the alicorn. All in all, she knew that her Highness had technically won fairly. She had behaved cockily towards the nighttime ruler, too, so right then and there, Rainbow realized that she needed to stop being so headstrong all the time. She understood suddenly that there were better ponies in the world. Most ponies would've thought that she would've figured all this out during her Iron Pony race with Applejack but apparently not.

This most recent incident, though, would be enough to make her finally understand the error of her egotistical ways.

Luna stirred awake, looked around the room for her pet, and saw Rainbow standing by the balcony staring out of the window towards the setting sun. The amber waves of light that slipped coyly passed the transparency forced her spectrum mane to glow much more radiantly than usual. Rainbow blinked as she felt her mistress's hoof wrap around her chest, and smiled when she felt Luna's tongue grace the back of her ear. She stopped for a moment with her aqua-like mane fluttering on her lover's cerulean coat. "Please… Ms. Dash… I'm truly sorry for what I did to you… have y-you been crying all afternoon?"

Rainbow shook her head, and luckily, the tears were slowly coming to a halt while she blinked the last one away. "Yeah, I have, but I'm done now… I know it's not right for me to behave like a little filly… Look, you're still my mistress, and I'll be loyal. It's what I'm best at, after all."

Luna slowly pecked Rainbow's forehead while allowing Rainbow to press against her frame. Several kisses would pass before she finally stopped, and prepared to give her pet a few assignments for the day.

"First," she said. A comb magically brushed by her tangled mane and formed it into the royal shimmers one would expect it to look like. "Second... your attire needs to be cleaned…" With a simple, petite whisk of Luna's enchanting horn, Rainbow felt her entire body light up in a fascinating aura of azure gleam.

Just like that, she was cleaner than she'd ever be. Perhaps, though, she was just a little bit too clean for her overall personal liking. Despite being a mare, she still didn't mind getting somewhat dirty, but the mystical cleansing was relaxing. Her mane was pulled back into a sleek ponytail with small, spiky strands hovering above her eyes, giving her a much more attractive appearance.

Her coat and tail were glossy and pristine just like her mane was. The maid suit almost shined with the last bits of light lines that slid through the balcony glass. Gazing at her treat, Luna squealed in delight while Rainbow just gave this disgruntled moan of displeasure. "Did you really have to make me so… fru-fru?"

Luna smirked and asked in a rather rhetorical tone, "Why Ms. Dash, I thought you said that you're loyal, did you not?"

Rainbow groaned as she rolled her eyes. "Yes, Ms. ... Luna…"

Her voice was unappealing towards referring to Luna in such a way, but with time, she'd learn to obey the norm of sexually explicit manners. "Good. Now then…" Luna began, summoning a bucket and sponge as she went along towards the door. Rainbow followed while the cleaning supplies were levitated next to her mistress. "These hallways are simply filthy. In order to ensure their tidiness, you must scrub the entire tile grounds with this sponge. No, you may not use a mop. To make it more entertaining for myself, I'll be watching you perform this task from afar. Follow me, please."

Rainbow slowly trotted next to Luna, and felt thoroughly agitated. They passed several turns before reaching the end of the hallway where a giant portrait of Princess Celestia hung on the wall. The bucket was then placed upon the floor. As for Rainbow, she warily looked to her right to see some of the nighttime guards. They were finally beginning their scheduled patrol of the palace, and some of them were walking along the corridor.

In the darkness, Luna and her pet could barely be seen. Luna's magic sparked and summoned the final piece of embarrassment that would make Rainbow Dash understand what this 'cleaning' business was really all about. A blue, wireless vibrator slowly floated in front of her eyes. It reflected Rainbow's lustrous gaze abstractly.

It serenely passed down between her fore and hind legs, comfortably sliding into her gap, and stayed there. It remained off for the time being. As it entered, Rainbow let out a few huffs of mental displeasure. She looked up at the grinning alicorn and muttered the question, "Is that… r-really necessary… err, Ms. Luna?"

She didn't say a word, but merely closed her eyes while holding back a jolt of excitement. Walking away from her pet, Luna explained, "I'll be controlling the device from my room. Try and hold out for as long as possible. If you… Well, you know… I'd say more than three times, I'll have to discipline you. After all, this could be considered a training exercise. Make sure that loosely hanging toy of yours doesn't interfere with your work, by the way."

After that warning which seemed more like a threat, Rainbow gulped and began scrubbing the floor with the vibrator still inactive. Suds and soap seeped through the furry hooves of the mare. Every furtive thrust was returned with grunts thanks to the device sinking further in. Rainbow tried hard to ignore the nice feeling she was experiencing along with the embarrassment that was coursing through her. "Why does she have to torture me like this?" Rainbow thought as she scrubbed some blackness away, "I mean, seriously? Is the vibrator really necessary? And those guards… What if they…?"

While Rainbow's mind continued to fluster with lewd imaginings, Luna began to fiddle with the controller. She placed the dial on low for the time being. Rainbow hunched over a coffee stain that some mare or stallion had spilled earlier, and then a sensational wave shot through her lower half. Her eyes widened once it started, and if this was the lowest setting, she feared how powerful it could get from there. Despite the distracting vibes she felt, she concentrated her best to clean the floors, making sure they were polished to a shine.

Finally reaching a roundabout, two other stallions were walking towards her. They both stared at her blushing face, curious if she was alright. The one to Rainbow's right approached and asked, "Are you okay? You look… so heated… Maybe you should take a break."

Rainbow knew he was just trying to be friendly, but stood and said, "I'm f-fine, now leave me alone!"

The other looked at her shaking hooves and speculated on what was happening. He could plainly see liquids smoothly sliding down her hind legs. He could even hear the vibrator humming, and decided to question her about the noise. "What's that sound?" He looked around sarcastically while continuing, "It almost sounds like… a fan…? No, more like a bumble bee…"

Rainbow gulped, and felt the toy increase in power. Luna wanted her to cum then and there, and Rainbow knew it. Rainbow understood this was another game her mistress was casually playing at. She was anticipating, and just waiting for Rainbow to succumb to the pleasure, something that the cerulean pony knew was sure to happen at any second.

Her teeth gritted while she muffled, "I'm… f-fine… Just go, please!" The two guards just looked at one another; stared back at Rainbow denying her request. Instead, they almost giggled at it. Just then, the dial went up a notch, and the potent vibes was finally able to send poor Rainbow Dash over the edge.

Once her legs felt the effective fluxes of the mechanism coyly driving deeper into her, all four legs gave out, and her entire frame lay loftily upon the floor. Her eyes closed as an intensive heat rushed through her. The sensation of being watched while she reached her peak was both arousing and tantalizing all at the same time.

Her moans ringed within the two smirking steed's ears, and for a moment, they felt themselves getting hard. The guards seemed to find the cumming pony very appealing both because she was literally giving them quite the show, and also her looks could pretty much dazzle anypony. Once she stopped after what must've been a whole minute, her huffs and slight moans were matched with applause and laughter coming from in front of her.

"Well, well… Somepony's really kinky tonight." The left guard snickered at his companion. Rainbow couldn't move. Her hooves felt numb, and her mind was filled to the brim with raunchy ideas. Just what were they going to do to her? Luna was going to just allow this to happen to her?

All she really cared about was just how intimidating all of this was starting to be, but fortunately, Luna wasn't going to allow any stallion-on-mare antics and shenanigans that night.

The two steeds' heads began glowing in the same, dim aura Rainbow recognized as Luna's, and slowly, they opened their eyes. They then began to walk off and interrogated each other about what had just happened. Rainbow heard Luna's voice in her head after that, saying, "My, my… Ms. Dash, that was an entertaining display you gave me, and those guards, but I can't have my protectors of the night be distracted with those kinds of thoughts, now can I? The forgetting spell works quite nicely with them, and in the end, it's better this way. Now then, please… Would you kindly return to your cleaning."

Rainbow grunted for a second, and then picked up the slack. She brushed up her own droplets that she had recently poured onto the floor not moments ago. Once she continued down the hall, several stallions passed by, all of which stared at her. Every time they came near her, continuing on their path, Luna would turn up the vibrator more and more, hoping to cause her cute pet to publicly cum yet again.

Soon, the dial was all the way up to sixty percent power, and Rainbow found it all too difficult to take that much teasing. With nopony around, she limped to the nearby wall, put her hooves up on it and breathed more thoroughly. Her eyes dilated as she reached down and slid the trinket further in while smiling.

Her forehead rested on the wall, and she felt herself inching closer and closer to yet another culmination. Her moans could be slightly heard down the hall, but with nopony watching except the Princess, Rainbow couldn't help herself but to let flashes of pure pleasure wash over her entire being. Soon, after a minute of cuming, she had yet another wet spot to cleanse. Quickening her stride, she hastened her performance.

She was almost finished. One more hallway, right after the final turn, and she'd be done, but her mistress wasn't planning on her making it. Right as she passed the final corner, the knob was turned all the way up to one hundred percent, forcing Rainbow to heavenly collapse.

She moaned loudly with closed eyes, amazed by the fact that she had managed to somehow underestimate how much strength the toy actually had. The noticeable sounds of Luna's sex toy could be heard down the hall. She was so close to her goal, but if she came one last time, she'd lose again.

Rainbow squinted her eyes and scrubbed vigorously. She tried her absolute best to do a good job, and just wanted to make it to the finish line before time ran out. Although despite all the effort that she had put in, just inches away from the door, she felt herself unable to continue. The vibrator bested her for the third time that night.

Dropping with a small thud, she wailed and panted with a small, displeased smile spread across her muzzle. Her hoof slammed once onto the tile floor while liquids slid down her legs. Once it was all over, she moaned between huffs and whispered curse words.

If there was one thing Rainbow hated, it was losing, and she had been losing to the Princess just one too many times. Her anger rose as did her body, and Rainbow then saw the door open. Luna exited with a kind smile. Her horn lit up and finished Rainbow's job for her. The aftermath of Luna's enchantment was a sleek, shiny, well washed tile floor.

Rainbow gulped and felt the vibrator reluctantly leave her pussy. As it popped out, she gave a slight moan of exhaustion and entered with a bowed head. Her hooves and wings were beat, and a little sweaty, but regardless of what state Rainbow was in, Luna turned and instructed, "Sit, please."

Rainbow did as she was told, and waited. She looked up at her mistress with worried eyes. That adorable look she made, and the way her ears were lowered while her lips trembled almost made Luna wish to give up the punishment, but that wasn't going to happen.

Her horn lit up in a radical light, and in less than a second, Rainbow felt her whole body flush with bliss. Her eyes rolled back as she collapsed. That cute, moist flank poked up a very little bit above the cold floor, and before Rainbow was able to understand what was happening, she felt a powerful orgasm bathe her lower region.

Four times, she'd cum, all in the same evening. This last one was the longest, though. Her mouth drooped ever so slightly as it ended, and before she could focus her vision on her mistress, everything became one big, and gigantic blur for Rainbow Dash. The worn out pony delved into deep slumber while Princess Luna magically placed her on the plush bed. She happily snuggled up with the ravished pegasus and delved along with her into a sleeping state. She was appreciative towards the maid for not only doing such a magnificent job on the floor, but also because she was so obedient as Luna's friend, too.
