The Curious Tale of Dr Shine and Ms Sparkle.

Mirage woke up startled, panting heavily. He looked around and found himself in an unfamiliar room.

“W-Where am I?” He asked himself, “By the moon what a weird dream I had last night.” Mirage looked around the room, and found it to be a small room. It was bare and lightly furnished, if Mirage was to take a guess he assumed it was a guest room. There was a knock on the door, and Mirage wondered who could it be?

“C-Come in?” Mirage spoke up, and his long time rival entered the room, “D-Dusk? W-where am I?”

“At the library.” I said simply, “You had a bit of an episode earlier, pretty much like I did when I first changed.”

“T-That wasn’t a dream?” Mirage panicked, I gave him a raised brow and mentally noted it for later.

“No it wasn’t a dream Mirage.” I explained, “That all happened,” I paused for moment, “And I’m sorry to say it won’t be the last time you change either.”

“W-What are you talking about Dusk?” Mirage looked confused, “What change?”

“The one that’ll happen at random for the rest of your life.” There was a tone of finality in my voice, “You’ll change gender just like I do, and there’s something else you need to know.”

“W-What?” Mirage asked, “What else is there?”

“You’ll eventually lose control, if you go without changing for so long.” I explained, “The change is like an addiction, you felt it right? That warm tingling feeling you get just as you change...and it doesn’t stop there.” Mirage gave me a frightened look, “Eventually you’ll start to crave the change more and more.”

“T-There’s got to be a cure right?” Mirage was practically begging, hoping I’d have some solution.

“I’m sorry...” I shook my head no, “But this is permanent, and it’s something you’ll have to live with...but I can at least offer some help...it took some doing but Mac and I have come to an agreement.”

“W-What agreement?” Mirage asked, “What did you two have to agree on that could of possibly help me?”

“...” I blushed, “Well, the main thing about the change is that it...well renders us in a state of arousal.”

“W-What?” Mirage looked at me dumbfounded, I sighed.

“In other words, the change makes you horny.” I grimaced over how crude that sounded, “And well...dealing with it is kind of awkward.”

“Just great.” Mirage groaned, “If you’re offering what I think you are, then sorry I’m not interested in you like that.”

“Really?” I folded my arms and gave a raised brow, “Trixie seemed to have other ideas.” Mirage gave me an unamused look.

“Look...” Mirage continued, “I don’t know what happened earlier, but that wasn’t what you think it was!”

“It took me sometime to admit it myself.” I replied, “I’m only trying to help you cope. This is indirectly my fault after all.” Mirage sighed and shook his head.

“No it isn’t Dusk, my own curiosity got the better of me once again.” He admitted, “I know it was stupid of me...but I just couldn’t help myself.” I sat down beside Mirage, and gave him a small smile.

“I’m not blaming you.” I reassured him, “I’m more concerned by who dropped those notes on your doorstep.”

“Uh-huh...” Mirage seemed distracted by something, he couldn’t bring himself to look away from his rival’s face, the soft glint in her eyes and how soft her lips looked.

“Mirage?” I tilted my head embarrassed, “Are you okay? You’re kind of spacing out.”

“W-Wha? S-Sorry I kind of zoned out there.” Mirage blushed, I sighed and frowned.

“Look I’m offering to help you...and maybe help you get this under control.” I blushed, “I-I mean I’m with Mac romantically, and Fluttershy...well I guess you can say we’re friends with benefits of sorts.” I giggled, “Relationships with multiple partners aren’t that rare in Equestria after all.”

“Just what are you getting at Dusk?” Mirage groaned.

“What I am getting at Mirage...” I said with a seductive smirk, “Is that I’m going to fuck you...”

“What?” Mirage looked at me with a confused expression.

“You can feel it can’t you?” I continued, “That small tingling warm that builds up inside you?” Mirage nodded slowly as he backed up against the wall, I followed suit and straddled him, “See I can’t help that feeling as much as you can...and it drives me crazy, if I don’t sate that desire often enough.”

I grabbed Mirage’s hand and placed it on my breast, he looked at me confused and I could tell he could feel my heart quicken, and my breathing getting heavier. I could see it in his eyes that he was starting to feel the same way to.

“I can see it Mirage, and I want to help.” I continued, “But I need to show you that this isn’t something to be ashamed of.”

“I-I feel hot...” Mirage moaned, I kissed him, “Oh fuck...this feels so good!”

“I know...” I let my hands drift down and caress his withdrawing member as it became a sensitive wet marehood, “It feels wonderful doesn’t it. It’s becoming a craving...and I...oh fuck....I-I want more...”

I could feel my hips expanding and swelling, oh it felt like heaven. I love the way my tight ass got bigger and plumper with the change. I cooed and groaned in bliss as my breasts began to grow in size as well. Mirage was in the same state I was, and he or rather she was doing her best to stifle a moan.

“Heh...” I grinned, “It feels wonderful doesn’t it? Here let me help...” I giggled as I removed her pants, exposing her wet pussy. I buried my head in between her thighs and began to tease that clit of hers with my tongue.

“H-Hah!!” She let out a cute moan, as I licked and sucked on her clit. I looked up to see her groping her growing breasts with one of her hands, the other gripping on the blanket, “D-Dusk...Oh....Hah-ahh!!”

I let out an amused chuckle, as I got up and stripped off the last of my clothing and Trixie tossed her remaining clothes aside on top of mine. My breasts continued to grow and swell further as the last of the changes began to set in.

There was a big difference between mine and Trixie’s figure. While I was big and curvy, she was slimmer but she certainly had a nice tight ass on her and her breasts were around a D cup if I had to guess.

“Now my dear Trixie...” I grinned, “Are you ready to play? Because Twilight’s going to show you how to enjoy yourself as a mare.”

Trixie nodded slowly, and I pulled her into my embrace. I kissed and caressed her neck, I briefly wondered if I should mark her with as mine. Trixie let out a cute moan as she felt something insert itself in her wet pussy, I snapped my fingers and a barely audible hum could be heard.

“Hahh! Fuck...FUCK!!!” Trixie cooed and moaned, as she trailed her kisses lower and lower until she was kissing my moist lower lips.

“Oh...fuck Trixie!!” I groaned, as Trixie licked, sucked and nibbled on my on sensitive clit, “Oh by the stars...” I tossed my head back and bit down on my lower lip. I focused my magic on the dildo that was currently in her tight pussy and began to move it back and forth, thrusting it deep inside her again and again. Each thrust causing her to throw everything she had into eating me out, “F-Fuck...fuck...OH FUCK!!!!”

Trixie turned around and wiggled that cute backside of hers. She whimpered cutely as I grabbed her ass and gave it a firm squeeze causing her to squeal in pleasure. I rubbed her clit with one hand and groped and teased her breasts with the other, kissing the back of her neck as the dildo continued to fuck her tight cunt.

“Oh T-Twilight...” Trixie shivered and moaned, the pace of each thrust getting faster. I conjured up another dildo which set itself in my own wet pussy and began thrusting at the same pace.

“Oh f-fuck!!!” Trixie pulled me into a kiss and soon we were fighting over who was on top, each kiss became more and more heated as we fought for dominance over the other. Trixie teased, and I responded in kind. All in all we had left the guest room in quite a mess.

Mac didn’t doubt what all that noise was, and he was debating on checking up on them just to make sure they were alright. He couldn’t believe Dusk had talked him into this.

“What did Ah do to get wrapped up in all this?” He muttered to himself. It was quiet for a moment, and against his better judgement he decided to see what was going on up there.

Mac walked in on me pinning Trixie against the wall, squirming and groaning as I mercilessly teased her clit as she got closer and closer to her climax.

“Ahem...am Ah interrupting something?” Trixie and I glanced at Mac, and an evil gleam in our eyes. Mac felt a cold sweat as he stepped back out of the room.

“Come here lover boy!” Mac found himself thrown and pinned on the bed, stripped of all his clothing. Trixie and I stared hungrily at Mac’s cock, and both of us began teasing his stallionhood. We took turns sucking and jacking him off, and it soon turned into a competition over who could suck him the hardest.

This continued back and forth between us, Mac grunted and groaned as we both gave him a blowjob he wouldn’t forget anytime soon. We were rough as we could be, as we kissed and sucked him. It guess the sight was too much for him as he came all over both of us, and us soon after considering those didlo’s had gone into overdrive with out desire and brought us both to our climax with a loud scream.

Trixie and I both collapsed on the bed exhausted and our faces and breasts covered in Mac’s seed.

“You know...” Trixie panted with a grin, “I could get used to this...”

“Beats losing it and fucking some random stranger.” I added, “Gender is fucking overrated anyway. I’m still gonna find out who took those notes one way or another.”

“Count me in...” Trixie agreed, “I want to have a few words with that bastard myself.”
