Cadence was smiling as she looked upon the erotic lesbian display before her. Spike’s carelessness has proven fortunate for her, her Mistress and one day her Master’s dreams. Certainly she had no desire to keep Rainbow and Gilda as simple lesbians, excluding their true Master nor would she permit them to be monogamous. But she knew that to the male fantasy there was something appealing about breaking a lesbian couple on their dick, and being the exception to their tryst.

"They were just having a fight over Soarin asking Gilda out, and I kind of stupidly asked if they could kiss and make up." Spike admitted, his back turned to the erotic display. As he tried to cover his ears so he wouldn’t hear their erotic moans. Such a gentledrake, such a noble and kind dragon. Much to be admired, but a trait that was holding him back from the fantasy coming true and him living the life of a dream.

But like all men there was a perverse side that enjoyed it, it was a side to Spike that Cadence very much enjoyed. A side that was causing her dick to harden, that wanted to turn around a jack off to the sight or ask a single sweet question that would bring the two women into his harem. Peeling one of his hands off his ear, and leaning in close so her sweet musky perfume was wafting through his nostrils like the smoke of a fire. And her hot breath teased his scales. "For now Spike why don't you ask them to take this somewhere private."

Cadence highlighted her point by pointing to the crowd of ponies who had gathered around the two girls. Unnoticed by Rainbow and Gilda cameras had been taken out and recordings taken.

“Right of course. Rainbow, Gilda. Do you want to take this somewhere private?" Spike asked the two. Who immediately paused as if just now realizing that others were watching.

"Yeah." Rainbow laughed, as if she was only mildly embarrassed by the events. “That probably would have been smart huh?”

“I don’t know, I was getting quite into it Dash.” Gilda teased her, hands not ceasing to grope Rainbow’s tits.

“G stop. I’ve got a rep to protect.” Rainbow squealed, as they walked. Naked with their clothes being levitated alongside them. “Oh I’m not never going to live this down… unless Spike.”

“Huh?”

“Can you please make it so all these guys forget about this?” Rainbow asked and it actually took Spike a moment to realise what she was talking about.

“Oh right… will all the ponies except us four forget about seeing Gilda and Rainbow naked and having sex. Oh and will their phones delete any images or recordings they made of them?" Spike asked, for once using his power in an intelligent and mature way. Much to Cadence's disappointment.

"Come on girls, me and Spike know a great motel to fuck in." Cadence promised them, leading them towards the motel that she had taken Spike's virginity in when he'd first made her desire to be his sex slave. On the way she used the opportunity to read the minds of the Griffon and Pegasus to understand what was going on.

Seems like this was all started by a simple love triangle, over that simple Wonderbolt Soarin. Such a silly waste in Cadence's mind but alas young ponies could be so immature when it came to their romantic issues. Ridiculous in the Princess's mind, after all there was a much simpler solution to the problem, the same one that the Princess had found to her Master. Not to mention Soarin wasn't a pony deserving of these two women, only her Master Spike deserved the two. But to Cadence she was certain she could fix this problem.

As they checked in to the motel the two lesbians immodestly began to return to their affections. Rainbow found her fingers digging into Gilda's cunt. “Now where were we?”

“I have a few ideas.” Gilda said, reaching around her ass.

As Cadence watched the display with rapt attention Spike took the opportunity to leave only to be interrupted by Rainbow. “Where do you think you’re going Spike?”

“Huh? I was going to step out-"

"What you don't want stay to watch?" Gilda asked with a sense of disappointment in her voice.

"Yeah you're both invited." Rainbow added, with a smirk on her face. Cadence looked at Spike with a look of delighted lust who returned with a look of utter confusion. Cadence immediately realised that when Spike that he when he said to 'take this somewhere private' he'd implied including himself and Cadence. But Spike didn't need to know that.

"It appears Spike we've got front row seats." Cadence said with a grin.

"But why? I never asked anything like that." Spike protested to Cadence even as Rainbow and Gilda continued their erotic displaying. Rolling onto the bed, with their tongues wretched down each other's throats as fingers began to explore the cunts of each pussy. Wings wrapped around the other.

"Perhaps Spike they just like you watching. Maybe that's always been true." Cadence whispered into her Master's ear.

"But they're not supposed to be lesbians." Spike said, now unable to keep his eyes from the display. Cadence's hand on his shoulder fueling his arousal helped highlight that.

"Then I suppose we should start fixing it, but we don't want them fighting again."

"Indeed." Cadence said, considering her words carefully, ready to manipulate Spike to his own fantastical ends. "To begin with we should make sure they're not going to start arguing again. So ask them if they're willing to share any man they're interested in, without jealously."

"That sounds like it would be wrong, changing them like that." Spike pointed out, Cadence responded by tripling the arousal she was feeding him.

"It would be hot though, wouldn't it." Cadence whispering, pulling him in close and pressing her own tits against him. "And wouldn't it be better if they could just get along and share? Isn't that better than them fighting?"

"I suppose that makes sense. Rainbow, Gilda would you two be willing to share any stallion together without being jealous of each other or any other girls?" Spike asked, his dick raising and hardening through Cadence's actions, her hand shifting from Spike's shoulder to her waist.

The two girls stopped and pulled away from each other looking at each other with a cheeky grin. "What do you think. Get Soarin together?"

"I don't care Dash, but right now I just want you." Gilda responding tipping Rainbow onto her back and spreading her legs.

"Can you do something about that?" Spike asked Cadence, who now could only turn her head in confusion.

"You'll have to be more specific."

"Twilight told me you could make ponies fall in love, isn't that right? Can't you also make them stop loving each other?" Spike whispered to her, and Cadence couldn't help but beam at what Spike had unwittingly done. Twilight being so young at the time must have been mistaken the nature of her powers, she couldn't do anything unless there was already an attraction. Or at least she hadn't been able to.

"I can indeed Spike." Cadence whisperedwith a glint in her eyes, cracking her knuckles as she got to work.

“Perhaps it’s best you step outside Spike, I'll handle these two. Privately I think some private details might come out." Cadence whispered to Spike. "But don't worry I'll be certain to invite you back in if there's any more action."

Spike blushed, as his hands tried in vain to hide his erection as he made his way to the door. At this point Gilda had her tongue buried into Rainbow Dash's snatch, bringing the Pegasus into a bright red blush and her eyes rolled back into her skull.

"He-Hey where did-ah where Spike go? AHH" Rainbow gasped as her arms reached around Gilda's head pulling her in. Cadence for her part simply smiled.

"Oh he just needed to step out for a while." Cadence lied effortless. "Toilet you see."

"The young kid probably had to jerk off, couldn't handle the pleasure." Gilda boasted with a proud grin.

Rainbow smirked. “Guess our sex is too awesome for him, his loss.”

Cadence couldn’t help but feel outraged on her Master’s behalf. He was being noble and chivalrous and how dare these bimbos not fulfil their purpose.

"That's enough." Cadence declared, her voice now wielding the spectre of a threat. Silencing the two girls in fear, both women now gazing upon Cadence in fear.

"That's-that's not funny Cadence." Rainbow stuttered out, with a weak worried smile.

"What's got you so pissed?" Gilda asked, pausing in in fear.

"You two do not know your place." Cadence growled, her horn glowed soundproofing the room. "If our Master Spike needs to be pleasured you rush to please him. To have him fuck you, as is your place as his slaves."

"Master Spike, Cadence what are you-" Rainbow asked, but Cadence's magic fused her lips shut. Her fingers touched the lips that refused to move. "Now listen to me."

Her horn lit up in a bright red light, beams like the thorns of roses tied around the two as petals bloomed along their skin. "You do not love Soarin, either of you. Instead you love Spike and always have done. More than that you love the thought of being his sex slave, of serving his whim and fancy. You will love for him to have every luxury and privilege in the world. And you love the thought of being a lesser slave than Rarity. You love the thought of being his sex slave and to bring the world under his domain.”

Cadence didn’t know whether Spike’s power of love could dictate what they loved, but she supposed she’d find out. Specifics could be decided later.

Author's Note

You know I don't even ship Rainbow with Gilda, much more of an Appledash shipper myself. Anyway next chapter will be a vote chapter so any additions to the vote roster will be welcome. Since I have specific plans to save Applejack until after Pinkie, and the CMC to be after Rarity they'll be removed from the list.

If there are any further ideas on what roles Rainbow and Gilda should play in the harem now would be a good time to share them.
