“Oh sweet heavens my head...” I groaned, wincing at the morning light shining on me, “This...is new?” I stood up or rather tried to and stretched. I turned to see why I couldn’t move, bits of torn clothing scattered everywhere and Mac and Luna were asleep naked beside me.

I looked down and saw the mess Luna and I must of made the previous night, the last thing I remember was having a few drinks before I began to feel funny.

“Yer okay Dusk?” Mac spoke up groggily, “Yer had quite the night, last night.”

“Mmm...” Luna seemed to purr as she woke up, “Best giantess sex I’ve had in ages...We really need to do that again Dusk.”

“W-what?” I stuttered, “Is this what Cadance meant by Alicorns and chocolate not mixing?”

“Hm?” Luna raised a brow, and giggled, “What the heavenly feeling of growing larger and curvier? Or how good it feels to just cut loose like that?” Luna yawned, “That first time is always so intense...”

“So chocolate equals a very horny and sexy giantess...” Mac stated, “Good to know.”

“MAC!!!” I shouted, “I can’t believe you said that!”

“Dusk...” Mac continued, “Ah got witness mah marefriend and princess Luna get bigger and curvier than any mare Ah’ve ever seen, get hot and heavy with each other...and yer expect me not to be turned on by that?”

“Um...I er...” I grinned sheepishly, “You’re not going to be gentle with me later are you?”

“Nope...” Mac stated in his usual fashion, “Yer ain’t gonna be walkin’ straight after Ah’m done with yer.”

“You have a thing for big curvy mares don’t you Macintosh?” Luna smirked, “Can’t say I’m surprised, you’d be surprised how often I’ve heard ponies fantasise about bedding me and my sister.”

“...” Mac said nothing, he knew fine well what she was getting out.

“Mac!” I shouted, “Don’t tell me you’ve thought about the princesses like that!”

“You’re just as bad Dusk...” Luna smirked playfully, “Me and my sister together like that...and Cadance as well.” Luna tutted, before letting out an amused chuckle, “Can’t say I blame you though, you and your brother seem to share a princess fetish...”

“Luna...please don’t bring my brother into this...” I blanched, remembering what happened the last time I had saw my older brother.

“Alright then...” Luna teased, “How about the one of Mac rutting you like crazy from all those months ago?”

“...” Mac looked at me in shock, “I-is that true Dusk?” I just nodded sheepishly, god this felt so awkward...

“S-so what exactly happened last night?” I asked hoping to change the subject, “I don’t remember much...”

“Our drinks had chocolate in them...” Luna explained, “Though I doubt Sunrise actually knew that at the time, I brought us here and then we indulged in a lot of growth, expansion and lesbian sex...Macintosh here seemed to be enjoying himself in between our breasts.”

“I kind of noticed...” I pointed to my chest, it still felt sticky from last night.

“Ah don’t regret nothin’.” Mac grinned.

“We really need to do that again...” Luna smiled at the thought, before giggling, “We would totally make all those other mares jealous.”

“Jeez what happened to the shy Luna I know?” I grinned, “Then again...that did feel really good last night...”

After a while of banter about the previous night we all got up, and stretched. I still felt a little groggy from waking up and my nethers still felt a bit sore, I let out a happy moan when my thighs rubbed together. I still felt so wet from the thought of last night.

“!?” I froze in place, and I reached down between my legs...and felt something moist instead of what was normally there.

“Dusk?” Mac asked, “What’s wrong?”

“I see that magic caused her change has had an unexpected side effect.” Luna used her own magic to give me a quick run over, “Well this is interesting, it would seem you body has finally finished changing Dusk...”

“What? But what about Twilight?” I demanded,

“Oh you’ll still change.” Luna reassured, “But as far as you’re concerned, the magic that caused you to grow last night must have finalised your transformation.”

“What how?” I cried, “I thought I wasn’t going to change any further!”

“You decided it actually.” Luna sighed and explained, “An Alicorn’s magic is more tied to our person than a regular unicorns, it’s like a part of our body which is why our magic affects us the way it does when it goes out of control. It only does so because we go out of control when we are overwhelm by our emotions. In a way our bodies reflect our magic.”

“...” I remained silent, this was a lot to take in. Was this why Twilight looks the way she does when I change? And was I fully a mare now because I desired it so much now? After everything that happened I had grew to resent that thing between my legs because even if I didn’t want to say it I was that much happier being a mare.

Granny Smith and Twilight Velvet sat in the living room happily chatting away, sharing stories of the antics their children had gotten themselves into.

Mac, Luna and I carefully snuck past them as best we could, thankfully we had found something to cover ourselves up to hide our embarrassment. We got halfway up the stairs before we heard my Mother yell at us.

“Dusk Shine! Macintosh!” Mom raised a brow at the other mare with us, “Luna? Why are you all naked under those blankets?”

“Um...” I hesitated, by the stars how do you explain to your mother that chocolate turns you into a horny giantess.

“Mac? What the hay is goin’ on here?” AJ asked as she stood at the top of the stairs behind us wrapped in a blanket, “Just what in tarnation happened to you two last night?”

“Jeez come back to bed AJ!” Was that Rainbow I heard back there? “It’s too early in the morning and I’m not done cuddling with you yet!”

“U-umm I would appreciate it if you came back to bed Applejack.” Wait was that Fluttershy? Oh god what the hell happened last night after we left.

“AJ get that sexy booty of yours back to bed now! It’s too early to be having a party right now...” AJ went bright red with embarrassment, well at least Mac, Luna and I wasn’t the only ones having fun last night.

“Ah swear you lot make the biggest racket Ah’ve ever heard!” Granny laughed, “Ah can understand RD but the other two?”

“Flutters can be really persuasive when she wants to be.” AJ answered awkwardly. Wow I didn’t realise Fluttershy had it in her, I guess it’s true what they say about the shy ones.

“That don’t explain the ground shakin’ last night.” Granny continued, “Ah swear Ah could have sworn it was a light earthquake.”

“Seriously though you two...” Mom scolded us, “What are you thinking sneaking in here like that? What kind of example would you be setting Applebloom if she saw you like this?”

“Um...can we discuss this later, Mom?” I grinned sheepishly.

Celestia stirred from her sleep, and for once she was happy she had the opportunity to sleep in for once. She noticed the sun was already up and assumed her magic did it’s own thing out of instinct.

She let out a content moan, her nethers felt so sore from the previous night. She grinned recalling how rough she was with herself last night, it had been so long since she had grown like that. Her bed was soaked, and the room smelt of her sex. What was left of her clothing was scattered on the messy wet floor.

“I really needed that...” She mused, she hadn’t felt this good in such a long time, “The first time this happened I ended up having sex with my sister...” She groaned at the memory.

Celestia noted to herself that this was a good way to cut loose and relax, and she had been unbelievably stressed lately. She mused that letting herself cut loose sexually would be a good way to unwind.

“Maybe Luna was right...” Celestia chuckled, “I need to get laid more often...” It just occurred to her she had a pony to fry, then again he did decide to trash her student’s home.

Celestia snapped her finger and in a flash all the mess had vanished, she showered and gotten dressed before making her way to the throne room.

Celestia had asked the guards to bring Iron Lance to her, she would have words with Flint Spark later but this matter needed to be sorted out as soon as possible.

Once everypony had gotten dressed I had to explain to my mother what had happened last night...minus a few details. I couldn’t help but giggle over how content Rainbow seemed to be cuddling up to AJ.

“Are yer gonna be like that all day RD?” AJ asked embarrassed,

“You’re comfy...” Rainbow muttered tiredly. By the stars Rainbow was so adorable right now.

“You two make a cute couple.” I smiled at AJ who blushed in response.

“Yeah who would have guessed RD would be such a cuddler.” Luna quipped, “You’re just as bad Dusk...” AJ laughed as I went red from embarrassment, Mom couldn’t help but chuckle at the banter.

“Oh boy...”
