A Princess is brought to heel

"Oh I’m not stupid enough to say, only that we should get to the rest of the harem now.” Spike replied, causing their mouths to fall open in outrage. “Maybe you two could figure it out together.”

The two realising what he was implying, smirked at each other. "If that's what Master wants."

"Then that's what Master gets."

They switched positions forming a 69 position, but Spike turned to Rarity as his attention shifted. His lovely fashionista lover embraced him as he turned, letting him take a good feel of her new cutie mark with his hands. A response that earned some lustful giggles of pleasure to sing from Rarity's throat.

"So enjoying your dream?" Spike asked, again there was no true need for his power. The answer would be yes either way.

“I am indeed Master, if Luna is watching us then I never want to wake up,” she replied, eyes staring into his with gentle but passionate love.

“I could make her mine with just a question you know. Or the entire world if you want, if it would make you happy.” Spike offered, giving her ass a firm grope, causing Rarity to let out a large moan of arousal.

"Perhaps later, after all we still have two Princesses here," Rarity pointed out, gleeful eyes turning to the alicorns in the room. "And I've heard a rumour that nopony can satisfy Cadence. I've always wanted to see if it's true."

Hearing her name being mentioned was enough to cause Cadence to perk up, and look hopefully at the two. Spike too saw the great opportunity to fuck the Princess of Lust herself, and he began to see her in a new light. Before as much as Cadence claimed otherwise she had always been the one guiding things.

Now thought he realised how hot it was, how sexy she was. Here was one of the Princesses of Equestria, an alicorn of unimaginable power, adored and looked up to by every pony in the Crystal Empire, an heiress to incredible wealth and power, and yet she desired nothing more to be his sex ****. His bitch. His fuck, with no desires of her own but to serve him. How far would she go?

“She was my first **** you know. The day that you told me about your fantasy, and the day I got the root she was the first one I ran into.” Spike explained to Rarity as they both looked to Cadence.

Cadence herself seemed to be excited but almost debating something, Rarity thought was intrigued. With a sly smile she asked: “is that so Master? And how long was it until she became your sex ****?”

“It was the same day Mistress,” Cadence explained, her voice becoming tinged with something unrecognisable.

"You certainly didn't wait for long Spike, and hear I was being told that I would have to convince you to embrace this power of yours, but it seems you've been playing the part of a Master for much longer than you said." Rarity teased, strolling up to Cadence.

"She came onto me, I didn't change her," Spike protested but all this did was elicit a grin from Rarity.

"Is that so? Does that mean that our resident Princess of Love has a secret submissive fetish?" Rarity asked, her eyes staring down Cadence like a hawk. Cadence for her part was almost melting under the gaze. "She's certainly hiding something Master."

"She is?" Spike asked, with genuine shock. Cadence herself could only flinch when called out, "how can you tell?"

“Applejack‘s not the only one who tell a liar dear. So Cadence what secret have you been keeping from our Master?” Rarity demanded Cadence, looking down at her.

In response Cadence placed herself onto the bed, stripping naked and offering her beautiful body to them. The body worthy of a goddess knelt before them, with a perfect hourglass figure, angelic wings spread out behind her as huge tits swayed enticingly. “Perhaps Mistress my secret is quite simply that you are not the only submissive in the world. Nor the only one obsessed with the Spike the Great and Glorious’s dick.”

“Well in that case dear we should see if you can serve your Mistress as well as your Master,” Rarity suggested, teleporting herself onto the bed and spreading her legs, her blue clit on full display. “Dig in dear.”

Cadence wasted no time, crawling over to the beautiful fashionista’s legs, delicate fingers wrapped around her thighs, they almost burned to the touch. Cadence and it seemed was capable to having a much greater heat than any other pony. She pushed the thighs apart, and her tongue rolled across her lips.

“I live to serve Mistress,” she purred as her tongue began to press against soft, smooth, white skin. Tempting and teasing her Mistress’s skin, making her way to the main event. Threading just smallest amount of her magic through her mouth and into her veins.

Soft mewls escaped Rarity’s lips, and her pussy started to get to work. A sweet smell like blueberries came from it as the cum began to leak outward. Cadence could feel her mouth salivate at the thought of her Mistress’s snatch.

“What do you think Master? Do you think I’ll be able to be one of the few who can satisfy her?” She asked, as Cadence wrapped her lips around Rarity’s cunt, exploring through her thin slit, searching for every creek and crack, hunting for the golden G-Spot.

“I don’t doubt you and me are the only ones who could satisfy her, right?” Spike asked with a raised grin. Rarity could hear only a muffled sound of panic escape Cadence’s lips as the Princess realised what was coming.

Rarity’s hands brushed through Cadence’s mane, as Spike towered behind Cadence. Something the dedicated slut didn’t realise, as her attention from just serving her mistress. “I bet that for her eating a pussy, or sucking a dick is as pleasurable as being right?”

Spike’s question elicited a moan of shock from Cadence, before a shiver of arousal rippled across her. The sound of gentle licks gave way to muffled moans, and dedication gave way to passionate excitement. Her previously steady body began to squirm in arousal, as her ass began to wiggle enticingly in Spike’s direction as her cunt grew tense from arousal.

So very tempting for a certain dragon, who also would not be satisfied even after fucking so many in his harem. The way her tail swished like an eager puppy was just irresistible for the dragon. Across on the other side Rarity, who was screaming in sexual joy with her hands clutching chunks of Cadence's mane, was only able to catch a small glimpse of what Spike was going to do. She gave the briefest nod to her dragon Master.

Spike plunged both of his dicks into Cadence, one in the ass and one in her pussy. Cadence could not keep herself focused, and was **** to break away from Rarity's cunt as she howled in pleasure. Frantic unicorn hands clutched Cadence's cheeks to prevent her from escaping. Sapphire lips muffled Cadence's screams as she brought the **** back under control.

"So if just one of us is enough to bring the Princess of Lust to heel, what will happen if she has to deal with both of us?" Spike asked, ramming into her behind, loud slaps of flesh against scales pierced the air.

Pulling away from Cadence's lips, Rarity gasped: "An excellent question Master. Cadence get back to it."

Despite being an alicorn of godly power Cadence found herself as weak as putty in her Mistress's hands, and could offer no resistance as she was pushed back down and Rarity's pussy was thrust back onto her lips. Nor did she intend to, addicted as she was to the taste of her Master's most beloved ****. To her it was as if Spike was fucking from two directions, pleasure rippling through her body in two directions like two waves in an ocean. Crashing into each other in a splash of ecstasy, even to the great Princess of Lust she was being pushed to the brink.

"I think she's about to burst," Spike commented, smiling triumphantly. Cadence gave another grunt of confession, much to Rarity's amusement.

"Poor little Princess, I guess everyone has limits," she cooed, a gentle hand pulling Cadence's head off her pussy by chin. Once the Princess's **** eyes looked into Rarity's, the fashionista's eyes sharpened and her mouth twisted in a scowl. "Well tough."

Cadence's eyes widened in shock, left on the edge of orgasm could only let out of soft mewl of betrayal. Spike himself was shocked, and found his pace halting in his track. Half of his cock still buried, the other half exposed to the elements, Cadence's cum dripping from it to the floor. "Rarity?"

Rarity's horn lit up, the same spell Cadence could use to block orgasms was done to her. Keeping Cadence on the top of her burning inferno of lust, **** tears rolled down her face as her legs wrapped around Spike’s waist. She tried to push herself onto his cock to bring herself to relief, but it was all in vain. "Why?"

"You my dear are still keeping secrets from us," Rarity pointed out, giving her a firm slap on her ass as punishment. "Until you tell us you tell us the truth, you'll be kept as drooling, **** little degenerate. Am I understood?"

Cadence's eyes widened with horror, even as Spike and regained his passion began to pick up speed. Turned on by Rarity's dominance, "she has a point you know. You can't be a true sex **** if you're keeping secrets from your Master."

Gasps and grunts of lust and disappointment broke out of Cadence's lips as her face fell onto mattress of the bed. Her limbs sapped of all strength as her blood carried only the lust of an orgasm denied. **** eyes pleaded at her Mistress, but she was unmoved. Instead ivory hands were placed around her checks, a mockingly gentle smile was sent her way, and Rarity channeled Cadence's own spell back at her. "Now dear please start opening up to your betters."

Cadence's eyes darted back to her Master, but he wasn't going to stop her Mistress, she could feel the pleasure overwhelming her. She needed to cum, but it was if her cunt had been welded shut. She needed to but she physically couldn't. She had ****. "I've been manipulating our Master."

She had cried it out in a moment of weakness, as if she had confessed that she had killed somepony. A silence permeated the castle as Spike stopped and every pair of eyes were drawn to her.

"Explain." Rarity demanded coldly.

She told them everything, the whole truth from the day she was made into Spike's sex **** to this very moment. How she had carefully schemed and plotted to corrupt his harem, piece by piece, one corrupted soul at a time. How she'd abused and tricked Spike into using his power, how his accidental question that made her believe everything she said was true, and how she was the one with the Root of Kindness. She confessed to it all.

"Well that's good to know I guess. Rarity will I always be able to see through Cadence's lies from now on?" Spike asked, and Cadence felt her heart sink in shame.

"I'm sorry Master, I had ****. It was important you embraced Mistress's dream, that you used your power to make your friends into your sex slaves. Do what you want to me, but don't undo Mistress's dream Master. Enjoy your harem and with our Mistress at your favourite." Cadence begged him, she thrusting herself onto Spike's dick.

The two lovers looked at each other, Rarity seemed amused, Spike didn't seem too angry. This all being a ploy to get him a harem of sexy sex slaves did wonders to his feelings of forgiveness. It was Rarity who spoke up first.

"I think I have a way Cadence can make up for her deceit. We need not punish Cadence, not when she can earn her way to redemption, and solve one of our prevalent issues." Rarity explained, a devilish smile on his face. Through Cadence's frazzled mane she could only look upon her Mistress with hopeful confusion, Spike gaze was simple confusion. "When she returns to the Crystal Empire she'll be out of reach for you to fuck, but should she employ a new hobby. She does have quite the figure for pornography after all."

"Well watching a few videos of Cadence entering porn sounds hot, but how does this relate to anything?" Spike asked his lover.

"That depends on you Spikey. If nothing else this ensuring you can enjoy this Princess's luscious body wherever, and whenever you want. But we could also publish it, and you may reap the profits. With a word you could make this an accepted profession, or you could ruin her reputation as punishment. But all things considered all she has done is fulfill our dreams, but it is your choice Master."

A/N: Next chapter will be a montage of Spike fucking the rest, as otherwise we'd never get to the rest of the story. So that also means next chapter will be a vote chapter. They'll be a poll both as where we expand the harem to, and for which background character should join the harem. Feel free to post suggestions, and give thoughts as to whether Spike should make porn an acceptable career or not.

When a new setting is voted on, it won't mean we'll abandon Ponyville or Ponyville options aren't available but Spike and Rarity will move to the setting and if we vote for a Ponyville character they'll have to be sent to the new location. Depending on things I might have Spike and Rarity's OC daughter come back to manage Ponyville when that happens.
