Soon after the magic lesson Rarity had returned herself to normal, as erotically sexy as her extreme form might have been it wasn’t practical for normal life, and truth be told it was far too extreme even for sex. Best kept as a secret weapon, for the times she and Spike really wanted to go all out. Or at least that was what Twilight thought.

Seeing Rarity off however she could tell that her friend was trying to hide her eagerness at the body changing spell that Twilight had taught her. Leaving Twilight to relax at the map of Equestria, satisfied with a job well done.

She wasn’t left alone for very long however as soon the doors of the palace was thrown open, to reveal a very happy and very satisficed Princess Cadence. Seeing her happy caused a smile to spread to Twilight's face as well, for this could only mean one thing.

“Good news?”

Cadence nodded, trailed her tongue across her lips. “The best. Rainbow is now part of our harem along with her new girlfriend Gilda. She’s promised to train our harem, with a little question from our Master her skills could expand to include teaching our slave how to fuck our Master all the more.”

"And Gilda?"

"Our hitwoman. Any men too nosey or too jealous to know what's good for them we send her to sort them out." Cadence explained, punching a hand into her fist.

Twilight nodded with a grin. "With Fluttershy, Rainbow and myself now made into Spike's personal whore, even if Fluttershy doesn't know it yet that leaves just Applejack and Pinkie Pie if we don't include Rarity. Applejack should be in Appleloosa but she'll be back soon enough."

"So I guess that means that that our next target is Pinkie then." Cadence noted. "She shouldn't be too hard."

"Oh I wouldn't underestimate me." Pinkie said causing the two Princesses to jump out of their seats. As Pinkie jumped out from underneath the table wearing a simple T-Shirt and shorts along with a wide smile on her face.

"How long have you been there?" Cadence asked the party pony, who tapped her chin in thought.

"For a while I think, since Twilight's turned Rarity into a living blow up doll." Pinkie explained, causing the two Princesses to glance at each other in shock.

"Why didn't you say anything?" Twilight asked her friend who shrugged.

"Oh it was interesting, so I wanted to watch. Also it looked like you were having a discussion and I've been told I interrupt people too often so I decided to wait patiently instead." Pinkie explained, causing the two to blink. The words patiently and Pinkie were rarely associated, it was to their horror that they would come together right now, in what was possibly one of the worst time.

"How much did you hear?" Cadence asked, her voice unnaturally cold and subdued.

"Oh tonnes Cadence. Like how Rarity has a kind of fantasy where we're all sex slaves, and how you and Twilight are way into it." Pinkie said with her usual chirper upbeat attitude which one couldn't tell was completely accurate to how she felt or a bold faced facade. Pinkie being Pinkie both and a thousand other possibilities could well be the answer. Then Pinkie started rambling. "Oh and you used Spike's power to make Rainbow and Gilda that way, I guess you two are trying to make even more ponies into Spike's sex slaves and have been keeping it a secret from him and Rarity so us and all our friends can convince them together."

Twilight's jaw dropped in shock, Cadence’s reaction was more subdued. She simply gripped the side of the chairs in the room. Twilight didn't know what Cadence would do to Pinkie if she was a threat to their dreams, whatever she did Twilight knew she would support the Princess. Even if they had to resort to drastic measures, Twilight wanted more than anything to be a slut just like Cadence, she’d do what was necessary no matter what it was.

“How did you find out?” Cadence demanded, like an officer interrogating a criminal.

"Just a hunch." Pinkie said with a shrug, leaving the two gapping like two fish.

"H-how does she-" Cadence asked thought Twilight simply sighed.

"Don't try to figure it out, I've tried it before it didn't work out." Twilight admitted with a groan, before collapsing onto her seat. "Well Pinkie you know now. What are you going to do?"

Over Twilight's shoulder she saw Cadence's horn lighting up as if ready to cast a spell on Pinkie, but her eyes glazed over. A sign that Twilight had learned meant that Cadence was using the Element of Kindness to read Pinkie's mind.

"Huh isn't it obvious Twilight? I'm going to join you as one of Spike’s sex slaves obviously.” Pinkie said, her head turning slightly. As if she was the one confused by Twilight’s lack of immediate acceptance.

Twilight glanced at Cadence whose magic dissipated as there was apparently no threat, and her eyes returned to full focus, having finished scrying Pinkie’s mind. Shooting Twilight a glance that told her that Pinkie wasn’t trying to trick them, she was completely sincere.

“You want to be Spike’s sex slave Pinkie? Why?” Twilight asked to which Pinkie seemed confused.

“Well why do you want to be Spike’s sex slave?” She asked, Twilight who blinked in shock.

“Because it’s my dream to be a slut like Cadence, more than anything. And if that means being a sex slave like her, and turning all the most beautiful women in Equestria then so be it.” Twilight admitted, but even as she explained herself she began to wonder if she had always been like this, or had Spike's power changed her. But that thought quickly faded as she came to a resolute decision. "And I don't care if I have to abuse whatever power exists in Equestria to make it so."

Behind Pinkie Twilight saw Cadence give her a proud smile, causing a fountain of lust, joy and achievement to burst out inside her heart. "I'm glad to hear it Twilight, I was worried you'd have limits. You're well on you way to being a slutty sex slave like me."

Twilight smiled, clutching her heart in joy. "T-thanks Cadence."

At that moment Pinkie took the opportunity to wrap an arm around Twilight's neck, slam her body against her side and have her free hand point at Cadence and Twilight in turn. "See being Spike's sex slave makes you happy, and it makes Cady happy, it'll make Rarity happy and Spike will be REALLY happy with a whole harem of sex slaves for him. Are Rainbow and Gilda happy being hypnotized into sex slaves?"

"They most definitely are." Cadence confirmed with a smirk. "Along with Fluttershy, Starlight and Sweetie Belle."

"Exactly." Pinkie exlcaimed, shooting Cadence a thumbs up. "So wouldn't it make all those beautiful and sexy mares happy? And me too?"

Twilight simply was stunned by her friend's logic, unable to keep up, she could only stutter a weak protest. "But-but they were hypnotized."

"But they were happy! Oh wait you wanted to hypnotized me? You wanted to twist me into some role like Rainbow and Gilda right?" Pinkie Pie hoped to one of her seats in the table, and squirmed impatiently. "Maybe you want to use Spike's Root of Honesty right? Or maybe your own? Or good old fashioned hypnosis? Maybe I could be a stripper and all my parties like orgies? Or something like that? Any ideas?"

Author's Note

Pinkie won, I'm not surprised since she was the only member of the Mane six on the list. I've received some great suggestions for what to do with Pinkie Pie, but any more would always be helpful.

The straw poll as to what people would ENJOY regarding the husbands are here: https://strawpoll.com/polls/QrgeVN6VRZp/results

But I realised that that straw poll was incomplete, because I also need to know what people are UNCOMFORTABLE with, so I've made another straw poll with that in mind. Link here: https://strawpoll.com/polls/jVyGJBRD9Z7

Again this is a survey, not a vote so nothing is guaranteed but if something has more people uncomfortable than enjoying it that would definitely influence my decision. So make sure you vote.
