An Explanation

"What the HELL just happened?" Spike shouted, his hands falling to knees as he stared daggers at the alicorn. Rarity too looked furious as she tried to comprehend what had just happened.

"You kidnapped us, **** us into this future, rallied those villains to stop us, and kidnapped me only to tell us that you want to be part of our harem?” Rarity shouted, eyes staring daggers.

“I admit that it’s a bit complicated-“

“You don’t say!”

“-but I do have an explanation. If you’d let me explain.”

“This isn’t some kind of trick, right?” Spike asked as a precaution, Flurry Heart simply shook her head.

“Even without the root that wouldn’t be the case,” she said, levitating over three large rocks. “Would you like a seat, Master?”

“Don’t-don’t call me that right now,” Spike sighed, collapsing onto the offered rock.

“Just start talking before I get angry," Rarity spat, enough that Flurry Heart recoiled noticeably. The alicorn took a deep breath and began talking.

"Do you remember that time when Twilight came from the future to tell herself not to worry for the next week?”

Spike thought back to that day all those years ago. "Yeah since she had an eyepatch, a crazy hairdo and a black outfit she thought she was from an apocalyptic future."

"Yes well, Twilight at that moment knew that Twilight would come from the future that would appear. It became history that a Twilight with an eyepatch, the hairstyle and a black outfit. And that Twilight assumed it was all because of some Pony Armageddon. Now what happened every time that Twilight tried to prevent that future from happening?"

"If I recall correctly everything she did only caused it to happen. Trying to do nothing caused her mane to get burnt, and when she tried to monitor everything she blinded herself and needed an eyepatch. Every attempt to stop it just ended up making Twilight look more like her future self," Rarity remembered, a finger pressed against her cheek.

"Exactly, now my past, and now your past has a Flurry Heart that came from the future. That Flurry Heart tried to prevent our harem from being formed, tried to rob the power from you, and kidnapped Rarity. Tell me what would have happened if we tried to prevent those events from happening at all."

Spike gestured for Rarity to answer since the Root of Honesty made it dangerous for him to ask those sorts of questions. "I suppose dear that anything we would do to stop it would only cause it to happen, just like with Twilight."

"Exactly, there's a stable time loop involved here, it’s history now. And because of that nothing could stop a Flurry Heart from heading back in time determined to bring an end to your dreams and stop you from bringing Equestria into your harem. And any attempt we make to prevent it from happening would only cause it to happen," Flurry Heart explained, "but while you can't prevent the future, or your past, you can trick it."

"Trick it?"

"You'll recall that pony Armageddon didn't happen in the end right?"

"Yeah, that was because that Twilight was only back in time to warn herself not to worry about the next week, but ended up being cut off by her past self. More of that trying to prevent the future causing it to happen."

"Yes but because it still APPEARED that a Twilight from Pony Armageddon came from the future the events still played out the same but no apocalypse needed to happen."

"Okay but how does that explain your overly convoluted plan?"

"Well because a Flurry Heart APPEARED to come from a future where she was determined to stop your harem, was neglected and miserable we had to make it so it only looked way. And up until a certain point history appeared at that point to be the same. Then that future, just like the Pony Apocalypse doesn't need to happen, if we didn't do that a Flurry Heart would still come from the future only that one would probably be doing it for real," Flurry Heart explained. "So basically we had to engineer a bootstrap paradox."

"And how exactly did you do that?"

"With mind control. You see Spike despite what my past self said, she was actually just a false persona. One I created with mind control, who had every bit of the intent to stop you. Who may have believed that she was neglected and miserable. But ironically she was the mind-controlled puppet, whilst I’m the Flurry Heart who acted with free will,” Flurry Heart explained, “and that real Flurry Heart the one with free will has no problem being part of your ever so sexy harem Master. It’s just like Auntie Pinkie said, the more people who are happy the better.”

“I don’t think Pinkie’s the best source for stuff like this Flurry Heart,” Spike said but the alicorn just shrugged.

“Eh, I’m not really too concerned about the whole morality angle of this. But the harem is my family, a horny family but my family nevertheless, and I’m not giving it up,” Flurry Heart said.

“Well despite how things turned out what you said before was right. We are doing something wrong here,” Spike sighed but he found his hands being embraced by his unicorn lover.

“Darling let’s be honest we were doing something wrong for a very long time, I threw out my morality when Sweetie Belle became my sex ****,” Rarity reminded him, “I suggest that we both take Discord’s advice.”

“Which is?”

“Just embrace it darling. I think we should both admit we’re the bad guys now,” Rarity told him an evil glint in her eye. “I think that’s something you secretly want too. We don't need to be cruel but let us be greedy.”

Spike looked at his girlfriend shocked, but he could tell that she was resolute on this. Almost scarily so. A part of him wondered if he should find those friends that Flurry Heart was talking about and remove the power. But yet another part of him was overpowering that instinct, one that was admittedly villainous and wrong. Yet it was a part of himself that Rarity could not help but love, and if he was honest it was a part of himself that enjoyed embracing. "I know it's wrong but I don't want to give this up. Especially when it makes you happy."

“I wouldn’t worry too much Master, it's just like Discord said. If we are to embrace this fantasy let us admit what we've become, ” Rarity told him, nuzzling her face against his arm.

“So now what?” Spike asked the two ladies.

“That’s up to you Master, the world is yours. Should we stay here Master? Perhaps explore this time period a little, or should we head back to our own time? Perhaps we’ve can catch up on our personal family time, I’ve missed you after all,” Rarity purred, her skin growing ever warmer as she grew ever more aroused just considering the thought. "Or perhaps this slut over there needs to be broken in a bit.”

Spike’s eyes shifted to Flurry Heart who pressed her breasts together enticingly, her body truly was beautiful. She had inherited the best aspects of both her parents, while her sizeable breasts were certainly nothing to sneeze at. Her hair sparkled like light reflecting against water, accentuating her beautiful hourglass form. Spike found her eyes exploring the Princess’s body and Flurry Heart found herself reciprocating, running her hands along her body enticingly.

“For now let’s head back to our own time,” Spike said pulling himself to his feet.

“As you wish Master,” Flurry Heart said, lighting up her horn and a hole in the fabric of time, not unlike the portal that Starlight had once opened up.

Rarity's hand wrapped around Spike’s with a smile. Before she turned to Flurry Heart. “I guess we shall have to think about what we’ll do with you darling? What role you’ll play, assuming you don’t already know.”

“I do, and trust me Mistress I’m looking forward to it.”

A/N: A lot of people were confused by the previous twist, so I hope this chapter helps explain it. It’s basically a bootstrap paradox though.

On another note I realised that I had been neglecting to update the tags on fimfiction with the fetishes. I’ve done that now, though I likely missed some so if anyone catches any feel free to comment below.

Also feel free to post any further suggestions on what should happen to Flurry Heart now.

Still need an editor, though I doubt there are many that can keep up with my schedule.
