It was one thing to wake up in the same room with your best friend sleeping in a bed nearby. It was something else completely to wake up with her snuggled in tight against you, your body still awash with the glow and lethargy of intimate times spent together. Twilight tilted her head and nuzzled Applejack's mane. She spread a wing over the still-sleeping mare and felt her squirm a little at the attention.

They were pressed belly-to-belly and, even as she was processing how good it had been to spend the special time with her friend, she realized something different about herself. "Oh my gosh, I'm a mare again!"

"Huh? Apple Bloom?" AJ stirred a little, her mind not fully processing that she was in a very different bed to her normal one, nor that she was certainly not alone. "Wha? Hay, Twilight what… oh…" Blush was the first reaction, the memories flooded the orange mare. "Did we… we did… was I…"

Twilight kissed the flustered Applejack's snout. "We did, you were, and, if you have any more questions, this should help." She pressed her lips firmly against her friend’s, watching as dawning surprise appeared and then faded into enjoyment. Both of them closed their eyes together and Twilight had just worked a forehoof between them, trailing it down toward her PFF's belly when the door burst open, Mayor Mare jumping in.

"Your Highness! Your Highness! We are all back to normal!" She had thus-far managed to not notice Applejack. "What did you do? This is wond-"

Words stuck in Mayor's throat as she noticed that the Princess of Friendship was not alone on the bed. Her eyes started to go wide and, very quietly, she turned and walked back from the room with stiff legs.

"Well thar goes any hope a this being a secret." Applejack gave a sight and tilted her head back up, kissing Twilight again.

The alicorn made sure it was a shorter kiss. "You really wanted to keep this a secret? This is Ponyville."

"Ah yer right. Hay Twi, you're a mare again!" Applejack blushed even as she nosed down there, past where the thick stallion length had been last night, to the soft folds of her friend. It was very different from using a hoof on herself, and indeed the mound was different from her own. It was Twilight's, though, so it meant that Applejack considered herself safe to explore. She sniffed it first, smelling musk. Carefully, she snaked her tongue out. It tasted musky too, odd, not bad. She licked again, and again.

Twilight didn't want to startle her friend but as her tongue worked more and more, Twilight couldn't stop the little moan from sneaking past her lips. Applejack paused and looked at her. "What? You can keep going." The alicorn grinned and turned herself so she got nose-to-tail with her friend. It took only a little nudging and nuzzling to get her own snout down and under Applejack's tail. "Apple," she kissed those dark orange lips, "thank you for telling me."

Applejack blushed hotly, that kiss was certainly a lot more interesting than the ones earlier and gave the mare the encouragement to explore more, licking and nibbling, gently playing and hearing Twilight respond to her investigation. Then it really sunk in, she was in bed, with Twilight. 'In-bed' in bed, at that.

Then Twilight did something with her tongue and AJ trembled, it was some kind of spiral just inside her that made her want to cry out, to buck a hundred trees. She sank her snout in deeper, hoping to get her best friend to feel the same way.

Gel slid, slowly, from Octavia. He had fed so very well not just from them but from the other ponies in the castle that he just wanted to split up and… no, he wouldn't be dividing anymore, things got too confusing. "You two hungry?" He stretched and looked over at the two mares who seemed to have had not only an insatiable appetite for sex, but also each other. Vinyl and Octavia, woken by his movements, had started up again. "Oh for… come on you two, wakey wakey! Rise and shaky!"

Vinyl tilted her head up from her mate's nethers. "Oh come on, what time is it?" Her green eyes went wide a moment and she moaned as Octavia found just the right spot.

"It's almost midday. I am going to cook some pancakes, you-" Gel blinked, two mares standing beside him, looking not the least like they had just been snout-deep in each others' vulva. "You like pancakes?"

"You bet." Vinyl nodded.

"Of course." Octavia agreed, her eyes dancing with suppressed comedy.

"Okay then, to the kitchen!" Gel started the procession and led the two out of the room and into the hall. A few other, confused-looking ponies were milling around. "Pancakes!" The procession grew until, by the time they got to the dining hall, there was nearly every party-goer from the previous night present. "Now, for pancakes! I need two volunteers…" Gel reached out and stretched his hoof, forming a pair of cute black collars around Vinyl and Octavia. "Perfect, please, my mares, this way."

"Did he just call us 'his' mares?" Vinyl looked to Octavia but saw it was a lost cause, the mare was giggling and trotting after the departing stallion. "Oh for… okay, coming!"

Twilight stepped into the room full of ponies at her tables, all of them talking and a few gave her a wave. "What's happening?" She looked around and felt a bump from the side as Applejack came in beside her. Eyes turned, a lot of eyes. AJ kissed her cheek.

The cheer nearly knocked them both back through the doorway. "What 'n tarnation is going on?" Applejack looked around but instead of an explanation Pinkie Pie appeared from nowhere and gave both her and Twilight a tight hug.

"I would just ignore it, they are being silly." Twilight didn't struggle against Pinkie's grip, she had learned just how strong her pink party pony pal was. "What did you get up to last night, Pinkie?"

"Oh, it was just the best party ever! I woke up and was a stallion, so I came up here to get an explanation and found some cute mares instead!" Pinkie was dancing from hoof to hoof. "Oh, and then Vinyl needed help with her speakers and all of us helped bring them up and then the real party started!"

Twilight looked a little dazed. "Well, I guess everypony needed to unwind a bit…" Something was biting at Twilight and she realized what it was. Having so many ponies in the castle felt… good. Everypony was just being friendly and having fun, the whole castle felt like it was alive.

Applejack watched as Twilight lifted a hoof up and bopped herself on the forehead. "What's wrong Twi?"

"The Castle of Friendship. I am the Princess of Friendship… I can't believe I missed this for so long… I need to find Vinyl Scratch." Twilight began to look around.

"In the kitchen silly, she and Octavia are helping Gel make everypony breakfast." Pinkie Pie was already serving cake that nopony could really work out the origin of. One moment Pinkie had been there, the next she had produced a huge multilayer cake.

"Thanks Pinkie." Twilight used her magic to scoop up some cream off the cake and smear it on her lips before she kissed the pink mare on the cheek. "Next time, we have a private party."

Pinkie just about vibrated through the floor with excitement. The last time she had partied with Twilight, Gel had gotten involved and Muffins too. She began making mental plans for the next time and served cake to her friends.

Twilight pushed the door to the kitchen open and stepped in. Inside, she saw Octavia, both back legs spread wide while Gel was doing something to her that had her… leaking… "Do I even want to know?" Twilight stepped around to help Vinyl with cooking the actual pancakes.

"We are out of syrup and… well, she is sweet." Gel gave a shrug, he had one hoof lifted up and under the mare's tail, pressed firmly against her plot and eliciting soft groans and whimpers from the cellist.

"Wait, really?" The revelation intrigued Twilight who stepped up and looked at the dripping fluid. Tentatively, she grabbed a spoon from the bench with her magic and dipped it under the stream. Bringing it to her snout she sniffed. It sure smelled sweet. "Okay, this has to be some kind of joke…" She put the spoon in her mouth and her eyes went wide. "Pretty good… but she will dehydrate if you keep this up. Get her something to drink, Gel."

"Good call Twi." Gel lifted a big jug of water up to the 'milked' mare's lips.

"Vinyl, I need to ask you something." Twilight returned to the other unicorn, then froze. Vinyl was completely ignoring her! "Vinyl?" Purple magic lifted the headphones off the mare's head. "Vinyl!"

"Oh, hi Twilight. Rocking party." Vinyl took back control of her headphones and settled them at her neck. "We will have breakfast ready soon, you can wait back-" Vinyl didn't get any further, she had an alicorn princess hugging her tightly. "Whoa, okay Twi, what's up?"

"You, silly. How often would you be good with to have more of these parties here?" Twilight grinned.

"Wait, you mean, regular like? But then I would have my own gig… I could…" Vinyl stopped and took a deep breath. "Your Highness, if you provide the space, I can have this place shaking every week."

Twilight beamed in delight. "That would be perfect!" As she trotted back out, her spoon nabbed a little more of that 'syrup'. "Wow this is good…"

"Hear that Tavi? I got my own club!" Vinyl did a quick shimmy-dance and pumped a hoof into the air. "Uh, Tavi?"

Octavia could only groan and moan, her body being pushed by the strange changeling to fill a whole bowl with her oddly-sweet mare-musk.

"I'll take that as a 'yay'." Vinyl slipped her headphones back on, grinning widely as she attended to the stove.

Spike woke slowly, feeling very full of… something. The wings folded over him told him, without waking, what it was. But then an extra set unfolded and the stallion sat straight up. "What…"

Stormwalker, once more as a mare, was stretching above him. "Morning." She sounded cheery and, despite himself, Spike couldn't disagree. Memories started to slowly filter into his head of the night before. Of needing to get Cloud Chaser to 'safety' and ending up getting him back to the castle and into his bedroom with the help of Storm. Things got a bit cloudy for Spike there, but there was definitely a memory of having two stallions at…

"Oh. Uh, good morning Storm." Spike looked so lost with what to say Stormwalker reached up and rubbed the stallion's head.

"Look, don't worry about it, I will be gone before your hunk there wakes up. It was just one night." Stormwalker smiled and, going on instinct, leaned in and kissed Spike's cheek.

"No!" Spike barked it loud enough Cloud started to rouse. "I mean, you can stay if you want. Not like we exactly have any secrets left…"

"Spike, not every time you bed a stallion or mare has to be pure and perfect love. We all had fun last night, we should leave it at that." Storm settled her plot down on the bed. "Honestly, it was good fun too, never realized how things would feel as a stallion, but he is yours, and you are his."

"Mmm, but you aren't bad… for a mare." Cloud reached a hoof over, barely catching the conversation enough to follow it, petting the other pegasus' tail. Spike nodded at the sentiment.

"Did anypony work out what happened? I don't think we were the only ones who got hit by it." Storm had decided to at least stay and talk, spending the night screwing her best friend and his boyfriend, then running out on them the next morning, just felt wrong.

"Think half the town got mixed up, most ended up here and… well, I think there was a good-sized party going on. I wonder if they have any breakfast going?" Cloud started to lift his head, wing pulling on Spike, tugging him to move as well. He surprised even himself when his other reached out around Storm. All three ponies blushed hotly and went silent.

"Well, it was fun, and I should…" Stormwalker looked to the door.

"And we should…" Spike did too, trying not to look at the mare.

Cloud looked between them, the sexual tension was practically thrumming in the air. "And we certainly shouldn't…"

"No!" Both Spike and Storm said it at the same time.

"What if I want to?" Cloud looked from one to the other and saw shoulders seem to lose all their stress and tension.

"Maybe." Spike nodded, grinning a little.

"Sometime." Stormwalker agreed. She immediately and silently cursed herself, she swore she wouldn't hook up with anypony in Ponyville, it was meant to be a short stay and then back to Cloudsdale. The best laid plans...

Author's Note

Ugh, waking up the next morning after a party can be horrible, but not if everypony wakes up with you and the party keeps going!

Also, Twilight realizes something very important about the castle and why it feels terrible when it is so empty.
