"D-Dusk? What the hell is going on?!"

Mac and I turned to the source of the voice. I was still feeling hot all over, as the changes continued. I was only half aware of who it was...I ignored him and focused my attention back towards Mac, nuzzling and kissing his neck.

"Ah...s-suggest..." Mac tried to get out, "Y-yer shut the door Spike..."

Spike did what was asked and silently wondered what his adoptive older brother was going through. Spike just seem hypnotized by watching Dusk's hips and back side fill out. He briefly wondered why Dusk’s cheeks were stained with eye-liner and why he currently was dressed like a mare. Despite his young age Spike was a lot smarter than he let on, and knew for a fact Dusk was getting off to whatever was happening to him.

"Just what's going on here Mac?" Spike asked, trying to distract himself...only to be cut off by a blissful scream from his brother now turned sister.

"I leave for a day or two and now I find you being necked by Dusk!" Spike pointed to my panting form, I was practically glowing as I was slowly coming down from an addictive high. "You two been dating behind my back or something?"

Mac just shot the young dragon a confused look, he fully expected a far different question to come from Spike. Mac took a quick look at Dusk’s now female form and immediately understood where Spike got the impression they were a couple. Dusk, or rather Twilight was a very attractive mare...he admitted that much. He wondered if Dusk held some sort of attraction to him which made Twilight act out on it.

"Yer not gonna say something about Dusk the whole jumping the gender gap thing?" Mac asked raising a brow.

"I was getting to that!" Spike shouted embarrassed, "What is going on with Dusk?"

"Ah ain't got a clue." Mac answered simply, it wasn’t the complete truth but Spike didn’t need to know about their previous encounter, "This seems to be happenin' at random...Ah don't think Dusk is even aware of it."

"It would explain the black outs, and his strange behaviour lately." Spike concluded, Mac’s ears pricked up showing Spike had caught his attention.

"Strange how?" Mac inquired curious.

"He's been acting more like...well like a mare." Spike answered, "He doesn't even realise it." Spike just looked on at me. I let out a content sigh being cuddled up against Mac's chest. "How long til we can get some answers."

"Just give her a bit." Mac replied simply, "She'll calm herself down in little while."

"So how did you find out about this Mac?" Spike asked, Mac just glared at him causing Spike to flinch a bit. "Okay-okay I won't ask..."
A few moments of awkward silence later I stirred from my contentment. I looked around only to be met with a very handsome stallion.

"To what do I owe the pleasure this visit Mac?" I kissed his cheek, "Did I leave that much of an impression?" Mac just remained silent and pointed towards Spike.

"Oh hey Spike when did you get back?" I asked unaware I was missing something.

"Just now Dusk..." Spike sighed.

"Twilight..." I corrected.

"Fine Twilight..." Spike groaned, "I just came back now, I made a stop at Rares..." Spike stopped speaking the second he noticed the dark look I was giving him.

"It would be best if ya'll didn't mentioned her Spike..." Mac explained, "Jus' don't ask...it would be better if ya didn't know."

"Well Twilight." Spike decided to change the subject, "Could you explain the whole gender swap thing I just watched?"

"Oh that..." I said sheepishly, "That was all Duskie, I don't know what causes it to happen." This seemed to unsettle Mac a bit upon hearing this. He could have sworn Dusk was somewhat aware of what was happening during the start of the change.

"Right so...your a different person then?" Spike tried to reason.

"Nope." I answered, "I'm still Duskie, just without all the awkwardness and shyness." Spike just groaned.

"Maybe it would be best to get the princesses involved." Spike suggested. “This is far too serious of a problem for it to go unchecked Twilight.”

"NO!!!" I yelled, "Please Spike don't tell them, Celestia will go nuts over this!"

"And why shouldn't I?" Spike argued, "Surely the princesses would be able to cure you of this? Dusk this isn't you!"

"..." I went quiet, and mumbled something under my breath. Mac heard what I had said giving me a shocked look.
"What was that?" Spike asked.

"I said..." I muttered quietly, "I like being like this..." Spike had heard what I'd just said and just sat down sighing. “I-I can’t help how I feel like this, deep down Duskie feels this way too, even if he doesn’t admit it.”

“How can you be so sure?” Mac asked. “I thought you said Dusk can’t remember anything when you change back.”

“That’s true.” I confirmed, “But like I said we’re the same person at the end of the day. I-I’m still Duskie, despite all the differences between us I act on my desires while Duskie is afraid to.” Silence filled the room for a moment after admission, “I’m not a bad person, I just want to live my life and be happy.”

“So all that flirtin’?” Mac asked curious.

“That’s just how I am.” I replied, “Maybe I’m a bit too forward, but I do try to be friendly.”

"Fine..." Spike groaned rubbing his temples, "I'll keep this to myself, but so help me could you at least try to be a little more...private about this?" He said pointing to both Mac and myself, "Whatever this is?"

"I'll try..." I promised, "I can't really help myself when the change comes."

"Just out of curiosity, does Dusk recall any of your antics?" Spike asked, I shook my head.

"No he doesn't." I explained, "And I'd rather it stay that way. It'll be better once Duskie figures it out for himself."

"Okay would you mind going over Dusk's notes on that project of yours and explaining it to us. It might shed some light on what's going on." Spike recommended, I nodded and got my research notes from the basement lab.

"So...You and..." Mac just shot Spike another glare.

"Shut it Spike..." Mac replied with utmost seriousness.

I put the research notes on the table, and began explaining what was going on.

"The basic premise was to use a crystallized catalyst as a binding agent for an enchantment of my own design." I explained happily.

"And the enchantment was to do what Twilight?" Spike demanded to know. I blushed slightly from embarrassment.

"It was...a confidence booster..." I explained sheepishly.

"Dusk's shyness..." Mac face palmed and groaned, "Of course."

"But what about the ingredients for the catalyst?" Spike inquired looking at the list of ingredients amongst the notes, "Some of these ingredients are dangerous Twilight, remember what happened when Applebloom got her hands on some Heart's Desire?"

"I remember Spike." I countered, "but Applebloom used pure Heart's Desire straight from the flower, I distilled it and ground it up into a powder. I even used the same method Zecora does. I did the same with the Crystallized Lust and Liquid Courage."

"So it's not the ingredients then?" Mac inquired.

"If anything crushing and distilling the ingredients removes the negative side effects, and the crystallization of the catalyst would have removed what was left entirely." I continued, "The catalyst exploded when the moonlight hit it which overloaded it causing the explosion. I never even got the chance to start binding the enchantment."

"She's right..." Spike explained to Mac, "If she did the enchantment would have used her in place of the catalyst when it was destroyed."

"See...I would have bound the enchantment to myself." I added in, "The catalyst was destroyed anyway, without the need for the spell. It's common knowledge that performing alchemy or enchanting super charges any magical property it hits."

"So what's bringing on these changes?" Mac asked me, "This has been going on since yer project failed, right? So there must be more to it."

"Well..." I theorized, "If there was something more the level moonlight would have made whatever is causing these changes permanent. Methods like the one I was using was intended as such." Mac and Spike a knowing look at each other.

"So there's no way to remove this?" Mac asked, "And ya'll be stuck goin' back and forth between Dusk and yerself."

"Yup." I confirmed, "That's pretty much the gist of it."

"Just how thorough is this transformation?" Spike inquired, "Can you get pregnant or the go through everything else a mare goes through?" Mac just blushed even redder than he normally was. He and I both knew how thorough this transformation was.

"It's thorough enough..." I explained simply. "Let's just leave it at that." I took the research notes back down to the lab, leaving Mac and Spike alone once again.

"So...what are you going to do about all this." Spike asked Mac,

"Keep mah mouth shut and a very, very cold shower." Mac replied, "And maybe try to do some damage control...Jus' keep this to yerself Spike...for Dusk's sake." Mac got up and headed to the door. "Ah'm got something to attend to Spike, tell Twilight I said goodnight."

"Sure thing." Spike responded, "Best of luck to ya man." Mac just nodded and left. I came back into the living room wondering where Mac had gone.

"Mac said he had something to take care of..." Spike explained, "Something about damage control..." I just stared and turned to the front door...part of me missed him already.

Mac stood outside the front door of the Carousel Boutique, knocking on it. He needed to have a little chat with Rarity about what happened.

"C'mon Rares open up!" Mac called out, "Ah'm just here to chat." The door opened up revealing a rather distress looking Rarity. She looked like she had been sobbing her heart out.

"Rares?" Mac raised a brow, "Ya'll okay?" Mac already heard what had happened from Dusk.

"I'm fine..." Rarity answered mutely, "I just did something completely and utterly foolish. I'll explain inside Macintosh." Rarity led Mac into her living room.

"..." Rarity was dead quiet, "I-I suppose I should start explaining why I'm in such a state."

"Dusk?" Mac said simply, "Ah know what happened Rares. Ah'm not here to judge jus' to get yer side of the story."

"...I see." Rarity replied in a sullen tone, "I-I lost control of myself, when I saw Dusk all dressed up like that I couldn't help myself. Oh it's so shameful for me to admit this, but the thought of shy awkward little Dusk dressed up and looking so vulnerable...I-I just couldn't resist."

"Ah know how yer feel about him Rares." Mac commented, "Yer ain't the only one..."

"Oh look at me..." Rarity continued, "You'd think with a body as gorgeous as mine I'd be able to snatch up any stallion I fancied..." She let out a sigh, "Dusk's been the kindest gentlecolt I've ever met, and there I blow it all away by being too forward...Dusk must think I'm such a utter slut."

"Rares Dusk think like that." Mac reassured her, "Ya'll know how shy he is..."

"That's just it though..." Rarity continued on, "I said and did such lewd and uncouth things, I came on too strong Macintosh...oh for...I titfucked him, sucked him off and got him to cum all over my breasts for crying out loud! I don't think he'll trust me with Spike anymore." Mac was surprised it wasn't often you heard Rarity use such crude language.

"Rares..." Mac spoke up, "Dusk's going through a really hard time right now, Ah'm not sayin' what yer did was right but it was poorly timed." Rarity just looked at Mac. "Like yer said Rares, Dusk's not the kind of stallion who would go out braggin' about gettin' yer in the sack. Jus' give him some time...Ah'm sure he'll forgive ya."

Rarity just stared at Mac taking in what he had said.

"I really hope you're right Macintosh." Rarity spoke up hopefully, "I love him too much to hurt him like this."

"..." Mac said nothing, "It's gettin' late Rares so Ah'm gonna shoot off back to the farm."

"T-thank you...Macintosh," Rarity replied, "Thank you for taking your time to listen to me..."

"Not a problem Rares." Mac answered back, "G'night."

Morning rolled over, I wondered what happened last night I clearly remember what happened with Rarity, as well as the chat I had with Mac about what Rarity did...after that was a blank though.

"Did I black out again?" I rolled onto my stomach, hugging the silk covered pillow. "Why couldn't I remember?" The last exact moment I remember was staring at Mac's face, how concerned he was over me.

"Urgh I have enough on my plate as it is!" I groaned to no one in particular, "C'mon Dusk pull yourself together! You haven't even made a start on finding out who this Twilight Sparkle is." I sighed, "Maybe it would be best if Celestia called in my big brother to help..."

If I keep blacking out like this, I'll never get anything done. I'm literally out for hours at a time, and each time I'm blacking out for longer periods. I got up, got cleaned up and dressed. Breakfast was a simple affair though I felt a little shorter...

"Morning Dusk." Spike greeted, "How are ya feeling?"

"Spike?" I asked curious, "When did you get back?"

"Oh I er got back last night," Spike hesitated, "I found you out cold on the couch, Mac says you just blacked out again. You had him really worried."

"Figures..." I groaned, "It happened again back at the farm, when I was alone with Mac." Spike seemed to raise a brow, as if he was trying to figure something out.

"Would it help if you asked around?" Spike suggested, "Maybe you can find out some info regarding this Twilight Sparkle everyone's going on about." It wasn't a bad suggestion, it certainly would be a start.

"Maybe I'll get on that today." I agreed, "That's not a bad idea Spike."

Spike just got on with his morning chores, and kept himself busy. He was deep in thought at what he had saw the previous day. He was worried about Dusk, and about everything that has been happening to him.

“Sorry guys but I’ve got to tell the princess about this.” Spike muttered to himself, “I’ll send the princess a letter once Dusk has gone out.” He hated breaking promises but this was for Dusk’s sake that he had to do this...
