Sunset hung upside down off her sofa groaning. Her body was drenched in sweat, dripping down her body from every pore and pooling in a puddle at the top of her head. The thin shirt she wore clung to her flesh skin tight. Her arms hung above her head surrounding her in the smell of her rank pits, she could close her arms, but that would expend emergency as well as only heat them up again. The AC in her apartment was busted yet again, leaving the only respite from this heat wave in the form of an oscillating fan. Just outside clear wavy ultra violet waves bombarded the surface. Clear waving lines where visible and insects buzzed.

“Unnggggg” she groaned “It’s sooooooo hot!”

The collar of her shirt looked like she dumped water on her face. Already her shorts where gone, displaying her panties to anyone who would walk by her window she contemplated just taking off her clothes and spending the rest of the day nude. Just then her phone beeped. She sat up and grabbed it off the coffee table, it was a group text from Rarity.

Rarity: “This heat wave is simply unbearable in my opinion. Who is up for a day at the beach?”

Sunset was about to reply when all of her friends in the chat started to before her.

Pinkie: “BIKINI BEACH PARTY!?! Count ME in!”

She also sent a gif of an alligator in a party hat with repeating confetti raining around it.

Rainbow: “I could go for some waves. Just let me finish my work out first.”

Apple: “After I make my deliveries I’ll meet y’all their.”

Fluttershy’s bubble started typing, then disappeared. Then reaped again. Then went away. Finally settling on sending a single thumbs up emoji.

They all seamed to unanimous agree to going to the beach today. Well almost everyone...

Twilight: “I can’t I need to study for midterms.”

Sunset raised an eyebrow and typed: “Aren’t Midterms months away?”

“Never to early to start studying.” she responded.

“NEEEEEEEERRRRRRRRRRRD” texted Dash.

Sunset rolled her eyes and typed: “I would LOVE to go but all my swim wear is in the wash. :(“

Twilight: “You could borrow one of mine.”

Sunset: “No offense Twilight but we aren’t the same size.”

Twilight: “The other me has a spell for that. Just send her a book message and I’ll meet you at your house at 8:00 today.”

Sunset: “Will do, see you then.”

Sunset rolled off her couch cracking her curved spine and made her way to the journal writing a message to Twilight explaining the situation. Princess Twilight soon replied back that she’ll be at Sunset’s house around the same time as human Twilight. Sudden Sunset realized something. She was about to see both Twilights at the same time. That almost never happened, the last time she could think of was months back. She wished she got to hang out with both of them more often. They where both adorable in their own ways, Twilight’s dorky glasses and cute snort along with Princess Twilight’s clumsiness in her human body. Sunset just wanted to snuggle up close to both of them and just... (No. No. No, bad Sunset.) She thought to herself. (Now wasn’t the time to fantasize about what it would be like for their purple skin to rub against her— Dang it! No! Stop daydreaming. Their your friends. You can’t jeopardize that be suggesting that they start dating.)

Sunset looked at the clock 7:28. Just thirty minutes and she could go to the beach. She just needed to keep cool for thirty more minutes.

Twilight Sparkle knocked on Sunset’s door. Along side her parallel dimension counterpart. The two Twilight’s had caught up on the recent events of their respective worlds on the way. Princess Twilight was very interested in the Equestrian magic leaking through the portal to her dimension, but didn’t really have a way to stop it on her end, though she would look into it after the coronation. Sci Twi was also interested in the lands surrounding Equestria, particularly the Kirin, but Twilight couldn’t answer many of her questions.

Sunset opened the door a funky odor wafted out, assaulting the Twilights nostrils. Sunset was soaking head to toe in sweat and barely dressed her clothes damp. She looked like she had just run a marathon.

“Sunset what happened?” Asked Sci- Twi.

“My AC’s busted, but don’t worry I have a fan and plenty of water.” Sunset responded

Both Sci Twi and Princess Twilight where wrinkling their noses. They couldn’t blame how little the fire haired woman was dressed, the inside of her apartment was practically an oven. Various empty water and Sparkle Cola bottles where strewn among Sunset’s uniform and some towels. The fire haired teens shirt clung to her skin in a way Sci Twi found incredibly erotic. (Ughh, no bad Twilight).

“So why didn’t you just bring a bigger swimsuit?” Sunset asked.

“I want to see what this gem can really do.” Twilight responded holding up said gem.

“Princess Twilight thinks I can use it as a conduit for spell casting.” She nodded over to said princess. “I’ve been looking for an excuse to test it out.”

“Is this safe?” Sunset asked.

“Of course,” Princess Twilight responded, “Expansion is the third spell I ever learned. It’s perfect for beginners.”

Twilight pulled out a white swimsuit from her bag and laid it out on the table. It was a blank two piece that indeed was too small for Sunset, but likely fit Twilights petite body to a T. Princess Twilight began to draw ruins with a piece of chalk on Sunsets table.

“Hey what do you think your doing?” Sunset shouted interrupting the alicorns preparation process.

“I’m drawing focusing ruins so the magic doesn’t go wild.” She explained. “Can’t be too carful.

Sunset remembered her days from magic school. Focusing ruins where mainly used for new magicians to help stabilize their magic. Think the training bumpers on the sides of a lane when you’re bowling. With no further objections Twilight sketched out the rest of the patter. Thought Sunset was annoyed that she would need to clean it up later, she stepped back away from the two purple skinned girls.

Once the circle was completed, Sci Twi pulled out a piece of yellowed paper and began reciting the spell. Listening to it put Sunset back in time to when she was Princess Celestia’s student. Though something was wrong. Sure she hadn’t cast a verbal spell in almost a decade now if Equis and Earth’s orbits where the same. But she was pretty sure Sci Twi was mispronouncing a good chunk of words. Before she was done the ruins began to glow.

“Wait.” Said Twilight “Why are they glowing?”

“Are they not supposed to glow?” Sci Twi suddenly stopped the incantation.

“No, their not.” She explained “The thaumaturgical energy is anathema to the posit—“ before she could finish lightning began crackled across the ruins just for a second.

“That supposed to happen?” Twilight asked taking a step back. Suddenly a swirling yellow and blue tempest formed. Sci Twi tried to run, but was slowly sucked in. Sunset was in utter shock, unable to move at the sight of the vortex of power in her own home. Twilight tried to push her counterpart out of it’s path but wound up getting sucked in as well.

~~~

The two Twilight’s tumbled around and around in the storm. Yellow lightning surrounded them. Surely by now the storm has swallowed at least a city block! But they where the only ones inside. A bolt of energy passed through them both, tingling energy wracking their bodies.

As the two Twilight turned around in the storm they felt their bodies stretching. Their organs and bones were flattened by the pull of gravity. Their clothes where torn to shreds by the storm. They felt their skin become even smoother and stretchy as their forms continued to change. They screamed as their spines arched back and their legs and arms reconnected to their bodies and fused in loops. They felt a tingling even more intense as all their hair was sucked into their bodies. Soon their mouths and eyes fused shut, however they could still see the swirling blue and yellow void around them as they tumbled around like clothes in a dryer. That description became more and more accurate by the second as more and more their bodies grew to resemble clothes more and more.

Particularly Princess Twilight became a bra and Sci Twi became panties. After a few more seconds they fell.

~~~

Sci Twi opened her eyes first. What she saw was a ceiling. Surprisingly Sunset’s apartment was still standing. However it seamed to have grown somewhat. She tried to rise up but found she couldn’t.

(Twilight, you alright?) Twilight asked.

(Yea I’m good.) Sci Twi responds. (What happened?)

(Well this is just a theory.) began her counterpart (But I’d say the ruins sucked in our souls into the clothes along with the unfinished spell.)

Twilight looked over and saw Sunset Shimmer. Hands covering her mouth in shock.

(Sunset this is important, I need you to go and start working on a counter spell.) Twilight began (There should be notes in other me’s back pack. If we don’t hurry... Sunset?)

The fire haired woman began slipping off her shorts and tank top exposing her shapely nude body to the two nerds. She then licked her lips and grabbed princess Twilight.

(Sunset we don’t have time to mess around.) Twilight ordered. (If we don’t hurry, ohhhh) Twilight experienced something like the back of her head being nestled between Sunset’s bosom and felt immense satisfaction as her hooks at the ends of the straps where secured snuggle to Sunset. Then the orange skinned hands enveloped her as she adjusted her breasts. As she did Twilight could taist the sweat on Sunset’s body as if she where licking her. It felt wrong but at the same time she began to heat up with pleasure as more and more of the salty liquid was absorbed into her body.

Sci Twi was next, she began to panic a little as Sunset lifted her up, folding her perspective to her own body. Then she felt the giant step inside her, trailing up Sunset’s legs, she felt her body expand as the nerd passed over those thick thighs till eventually reaching a soft stopping point between her thighs. It felt so wrong, yet at the same time there was a part of her mind assuring her that this was where she was meant to be. She could only imagine her counterpart was experiencing something similar.

She felt Sunset begin to walk slowly the back of her head rubbing against the former demons cleanly shaved crotch. She could almost taist the sweat soaking into her with every step.

Then she stopped in front of a full body mirror.

“It’s peeeeeeeeerfect.” Sunset purred pulling Twilight out of her butt crack, thankfully she couldn’t taist from that end, but she could taist from the front.

(Sunset this isn’t the time to fool around.) Twilight pleaded. (We don’t know if this becomes irreversible after a certain time limit or not.)

(I don’t think she can hear you.) Panties Twilight observed.

Princess Bra Twilight sighed.

(You might be right,) she admitted. (I really am sorry you’re stuck down there after casting your first spell.)

(It’s not so bad.) Sci Twi responded. (At least Sunset shaves down here.)

Princess Twilight blushed hot red. Although it seamed like her fire haired friend didn’t notice.

(Lets just pray this wears off soon.)
