“I’m really grateful that you came with me Mac.” I thanked Mac, “I’m surprised that you could find the time to, I know how the farm keeps you really busy.”

“Don’tcha worry yerself about it Dusk.” Mac smiled, “Besides Ah reckon AJ can handle it herself. Ah’m surprised we have to go all the way to Canterlot for the Hospital though.”

“Well that’s where my family doctor is.” I explained, “I can just imagine what she will say when she see’s me now.” I sighed, “It’s been one hell of weird week for me.”

“Really? Twi hasn’t gotcha in to any trouble has she?” Mac asked raising a brow. I wasn’t sure how to explain this to my coltfriend.

“Well aside from Luna becoming my new mentor.” I hesitated, “I kind of figured something out about my changes Mac, and it worries me.”

“And what’s that Dusk?” Mac inquired, wondering how this could worry Dusk that much.

“I need to change often Mac, if I go without changing for so long...” I hesitated again, “I lose control and go into a lust driven frenzy.”

“Does anypony else know?” Mac asked, “Ah mean that is very serious.”

“Only my brother, Cadance, and Luna know.” I explained going bright red from embarrassment, “Luna is the only who can help though, and maybe you...now.”

“Why not Shining and Cadance?” Mac asked out of curiosity, I remained quiet out of shame, “O-oh...r-right...”

“I-I hope you don’t think less of me for what happened.” I said quietly, Mac just kissed my forehead.

“Nah Ah kinda get it, AJ and Ah are the butt of all the incest jokes from the ponies that don’t like us.” Mac explained, “Best one Ah’ve heard is that they think Applebloom is mine and AJ’s kid.” He let out a snort of amusement because of the utter stupidity of someponies.

“I’m glad you don’t think less of me because of all this.” I stated, utterly relieved, “I think Luna will be able to help me keeping that under control.”

“How so?” Mac raised a brow, “She got some kinda spell that stops yer losin’ it?”

“Umm.” I hesitated, “Luna had to take me on as a lover, for me to be her apprentice. Apparently sex is a big part of some of the rituals of the night, it’s just part of the apprenticeship and nothing more...I-I swear.”

“Oh really?” Mac got a devilish grin, “Well maybe Ah might want to see what she has to teach yer.” I blushed as he whispered that into my ear.

Canterlot was quiet given the time of the morning, I was worried we might run into my parents. I don’t think I’m ready to explain my appearance to them just yet, never mind the fact I’ll suddenly jump the gender gap at random.

We finally arrived at Canterlot central hospital. The reception was huge, much larger than I remember it being but then again it has been a few years since my last visit.

“Hello...” I greeted the receptionist, “I have an appointment to see Dr Rainheart.”

“Could I get your name please so I can let her know.” The receptionist asked in a polite friendly tone.

“D-Dusk Shine...Dr Rainheart is my family’s doctor.” I replied, the receptionist did a double take. I could take a good guess what she was thinking...she was clearly expecting something else.

“Is the stallion beside you going in with you?” She asked, I nodded blushing, “Okay than I’ll let the Doctor know you’re here to see her.”

We waited in the reception, I couldn’t help but notice the glances I was getting. Should I have worn something different? I was wearing a pale yellow summer dress, a matching scarf and maneband, and a light amount of make up.

“Dusk yer okay there?” Mac asked, concerned about all the glances I was getting.

“I-I’m just a little nervous...” I replied, “There’s a lot of ponies who know me by my reputation alone, I should have figured I would have attracted a lot of attention.”

It was somewhat of a long wait, before the nurse called me and Mac into Dr Rainheart’s office. She was going through my medical file, as she greeted us not fully paying me any attention.

“So Mr Shine how can I...help you...?” The doctor looked up at me slack jawed, “I-I’m sorry miss but...o-oh my...” The doctor finally recognised me, “Oh my Dusk take a seat please.”

Mac and I sat down, and I explained what had happened, even the parts about Twilight though I left out the parts about all the sex. The doctor listened intently to my problem.

“Right would you mind following me Dusk, I need to give you a full examination before I come to any conclusions as to what should be done.” I followed her into a private examination room which was in the next room over. “Right Dusk I’m going to need you to strip down out of your clothes.”

I did what was asked until I was completely nude, out of shyness I covered up breasts and...that thing...between my legs that marked me as a stallion. The doctor raised a brow, but said nothing.

“Right Dusk, I ‘m going to take a few measurements alright?” I nodded, and she did exactly that much to my embarrassment. A few moments later she had finished, “Well you’ve obviously lost some height, but the wider hips and the development of breasts is something to be worried about. I’m not detecting any magic that shouldn’t be there...so you don’t have to worry about changing any further than you have, other than this transformation you told me about.” I felt a little reassured hearing that, “I don’t doubt you could reverse this with magic, but it would be pointless as your body will just revert back to this over time.”

“Is the magic doing this that strong?” I asked.

“Dusk I’m sorry to be one to say this but you’re going to be like this for the rest of your life.” There it was, I know I have heard it before but I hoped there was some way to undo all this but the cold bitter truth was something I didn’t want to hear.

“N-no...I-I don’t want to be stuck like this!” I cried, “T-this isn’t fair...”

“Dusk I know you didn’t want to hear that,” The doctor continued, “but it’s the truth. Just because you look like a mare isn’t something you can’t learn to live with, you’re still a stallion.”

“...” I said nothing, my silence echoed throughout the room.

“Dusk?” The doctor gave me a worried look.

“...I-It’s not that...” I said quietly, “I-I don’t want that thing between my legs, I just feel so confused right now I know I’m a...s-stallion, but I’m just as much a mare as you are.”

“Dusk...” The doctor spoke up, “How long have you been feeling like this?”

“...” I hesitated, trying to word my thoughts carefully, “Ever since I became an Alicorn. Everpony notices the princesses, but I’m a prince and no one pays me any notice unless I screw up in the most major way possible. When I’m Twilight everypony pays attention to her, I could walk by and nopony would notice. The only reason ponies here in Canterlot know me is because I was Princess Celestia’s student.”

“I see,” The doctor stated. “Now Dusk...I have to ask how many sexual partners have you had, even as Twilight?”

“...” I paused for a moment and blushed, “Four...technically five, but that was something that went too far. All but one was as Twilight. Mac is my current partner.”

“I’m sorry to say this Dusk, but there’s really nothing I can do...” The doctor explained, “For all intents and purposes you’re perfectly healthy, but, should something happen, here’s my private number. Please let me know as soon as possible.”

“I will doctor, thank you.” I got dressed and left the hospital with Mac.

On the train back, we got a private carriage and Mac was worried about me, as I hadn’t spoke a word since we left the hospital.

“Dusk yer okay there?” he asked concerned, “Yer’ve been awfully quiet since we’ve left the hospital.”

“I’m just thinking...” I answered, “The doctor said I could reverse the change with magic, but I would eventually revert back to what you see now. It’s more or less pointless to even try it.”

“Ah’m sorry yer had to hear that.” Mac stated, “At least it can’t get any worse right?” I nodded in confirmation.

“Mac...” I asked going bright red, “All the times we’ve...you know...I was always Twilight wasn’t I?” Mac nodded, not sure to what I was getting at, “Then just this once, could you let me do this...”

I pulled Mac into a kiss, silently pleading that even it was just this once I wouldn’t change into Twilight like I usually do. Mac was surprised as I was, as my hands drifted down to his crotch and began to message him through his slacks. I could feel his stallionhood getting harder by the moment, and I made my way down and unbuckled his belt, and undid his fly freeing him.

“D-Dusk...” Mac groaned out, as I rubbed his throbbing cock against my cheek. I kissed, licked and nibbled his shaft before taking it into my mouth. I teased him a much as I could, awkwardly bobbing up and down as I sucked him.

Mac looked down, knowing full well who was on their knees giving him a blowjob. He wondered if Dusk always looked so sexy, and was silently surprised he hadn’t turned into Twilight. Mac knew most mares back in Ponyville would kill to be doing what Dusk is currently doing, and not one of them interested him, how could they after what they did to Fluttershy.

“Mmmphf...mmm!” Mac groaned as the cute and sexy feminine sounds Dusk was making was driving him insane, as Dusk was going to town on his shaft, “Mmphf...mmm! Mmmphf!!”

To Mac Twilight was pretty much a sex goddess incarnate, but Dusk? Mac was definitely sure he could give Twilight a good run for her money.

“H-haah...by the stars...” I panted getting my breath back, “F-Fuck you’re so big...I can feel your cock throb while it’s in my throat.” I took his shaft in my once again, determined to make him cum for me.

“D-Damn...Dusk...” Mac groaned again, “D-do yer know how many mare’s would kill to be where yer are right now?” I let out a muffled giggle, and continued worshipping that cock of his, “Oh f-fuck...Dusk...” I could feel his cock build up and throb in my mouth, he was getting so close which only served to make my suck him all the more. I gave his balls a gentle squeeze which drove him under the edge. With a roar of pleasure, I could taste him as he exploded in my mouth, I swallowed as much as I could until he finished. “H-holy fuck...” Mac panted, “D-Dusk...?”

Mac looked down and was greeted with the sight of me crimson faced, my mouth wide open showing him how much he came in my mouth before I swallowed it. Mac looked at me wide-eyed in surprise.

“Do yer have any idea how much Ah want to rut you right now Dusk?” Mac groaned, I gave him a teasing smile.

“Maybe some other time...” I grinned, “We’ll be arriving in the next couple of minutes.”
