It had been a few weeks since James had become Jessie due to a mix-up with the local ReNewU spa. They had been implementing several new systems over the past couple of years using the latest in bio-transmutation-technology, including a melting spa. Long story short, James was accidentally melted down and reformed into the same body as her now-girlfriend, Evie.

Despite the confusing experience, it didn’t take Jessie long to become accustomed to her new body. It helped that someone who had experience with her own body was there to help her.

“It actually kind of scares me how quickly you got used to being a girl all of a sudden.” Evie said.

“It’s not that bad. I mean sure it took a lot to explain at work, and even longer to explain to my parents… mostly because my mom fainted halfway through…” Jessie replied, “But it’s not that much different, really.”

“…being the opposite gender.”

“Other than the boobs, which totally get in the way. How do you women live with these things? I mean, yours are bigger than most but…”

“Hey. They’re yours too now, missy.”

“Sure, rub it in why don’t you.” Jessie groaned. Evie grinned, and stuck her hand down Jessie’s top, rubbing firmly. “Hey, quit it! I’m driving here!”

“You said to rub it in.” Evie laughed, “Besides, that’s my body you’re using. I technically have full legal rights to do anything I want to it.”

“Myeh myeh myeh!” Jessie mocked, “It sucks how many people mistake me for you though.”

“Can you blame them?” Evie asked, “I told you to cut your hair short so we’d look different!”

“But I like long hair.” Jessie pouted, twirling a lock in her fingers. “Especially yours.”

“Do you know how hard it is to fight with you when all you do is indirectly compliment me?” Evie sighed, in mock exasperation.

“We’re here.” Jessie pulled into the parking lot of the ReNewU Spa.

“How can I help you today?” the receptionist asked the twins walking in. “Ahh, two of my favorite customers.” She smiled at Evie and Jessie. “The standard two melting saunas?”

“That would be great, thanks.” Evie said, handing over her membership card. The receptionist scanned it in, looked up at Jessie, and scanned it in a second time.

“You know, you really should just get your own card.” The receptionist sighed at Jessie, “I’m not technically allowed to do that.” She handed it back to Evie.

“But it’s so much easier this way. We’d have the same photo, and use the same mold anyway…”

“That’s not the point. You’re skimping out on an entire member’s monthly fee! If you don’t sign up, I’m eventually going to have to ban you both.”

“Why both of us!” Evie protested.

“Because no one can tell you two apart.” The receptionist stated matter-of-factly.

“Fine, I’ll sign up on my way out.” Jessie sighed. The receptionist smiled in response.

“Oh, by the way! We’re trying to find people to test our new group saunas.” The receptionist suddenly perked up.

“Group saunas…?”

“Yes, it’s just the same as the ones you’re used to, but you can do it in the same place. A little less lonely, if you would.”

“That’d be nice.” Jessie said, looking at Evie, who nodded.

“We’ll give it a try.”

“Excellent!” the receptionist clapped her hands together, and offered Evie a different key. But before she could accept it, she held it back. “Oh, I have to warn you. It is a prototype, and we’re not sure we have all the bugs worked out.”

“Isn’t that kind of dangerous?” Evie said, showing worry.

“Well, that’s why we need testers. I’ll need you to sign these release forms, actually.”

“You’re kidding.” Jessie said, staring at the small book of papers the receptionist put on the table.

“We don’t want to be held responsible, obviously. But it shouldn’t be anything dangerous, all bio-transmutations are reversible under the right circumstances…”

“Ahem.” Jessie cleared her throat.

“…yes, um… Almost all… the point is, you’ll be safe. And should something happen, we’ll compensate you to the best of our ability.”

“What does that entail?” Evie asked.

“Well, for starters it’d be free… since you’re doing us a service.”

“Done.” Evie stated, signing off her name to the stack of papers.

“Wait, what? Evie!” Jessie exclaimed, “We don’t-“

“We’re getting free stuff, who cares? Come on.” Evie laughed, grabbing the key out of the receptionist’s hand with one hand and Jessie’s hand in the other, dragging her off.

“Happy melting you two!” the receptionist called after them.

“…Is this it?” Jessie asked, staring at the hole in the floor. The room they had been directed to was similar to the melting saunas they were used to using, but instead of having a glass booth in the floor, it was at least four times larger, and had no glass covering. “It’s like they just made a hole in the floor and called it a day.”

“Well… it’s the same material as the booths.” Evie said, poking it with her foot. “And there’s the control panel.”

“But… I thought she just meant there were two or more booths in the room. Not one large tub.”

“Yeah, me too… Oh well.” Evie said, starting to strip.

“Wait, but if we both use the same one… won’t we uh… get mixed up?” Jessie said, worried.

“I’m sure they’ve thought it through.”

“…alright, but I’m staying way over on my side.” Jessie gave in, peeling off her shirt. “We probably shouldn’t touch each other at all, in fact.”

“You worry too much.”

“Considering what happened the last time I did something here without thinking?”

“…a fair point.” Evie hopped into the tub and crawled over to the control panel. “Now get in here.”

“Fine.” Jessie pouted, stepping out of her panties and into the tub.

“Now, how about a nice, slow, long, melt.” Evie suggested, flipping through the options.

“Uh… I’m used to quick ones, to be honest…”

“Well, all the more reason to try something new.”

“Aren’t we already trying something new?”

“Yes, but if I don’t force you to you’ll never try things like this. Remember how long it took to get you down here in the first place?”

“Oh, alright.” Jessie said, sitting down on the bench-foam of the tub. “Start ‘er up.”

“Gladly!” Evie smiled, punching the big red button. It wasn’t long before the both of them began to feel a familiar warmth spreading through their bodies as they began to melt.

Evie looked up at Jessie who was lying more or less perfectly still. “Is that how you use the personal booths too? Just lying completely still?”

“Yeah, what of it?”

“Booooring.” Evie snorted. “You’ve been here how many times and you still won’t try anything interesting?”

“You say interesting, I say weird as hell.”

“It can be both!” Evie exclaimed indignantly. “Besides, I chose a long melt so that we could mess around longer!”

“Fine with me, do whatever you want. I’m content to sit here and relax.” Jessie smiled. “Though it is taking awhile… I still feel pretty solid.” She lifted up an arm to inspect herself, there was barely a drop on it.

Evie frowned. “That’s because of how slow I set it. You can speed it up y’know.”

“How’s that?”

“Adding your own heat. Physical movement, etcetera.”

“What do you mean?” Jessie asked, quizzically.

“Like this.” Evie began rubbing her ankle vigorously with her hands. Jessie noticed her hands were beginning to wear through her ankle as the rubbed flesh melted faster.

“Oh.” Jessie said, watching Evie continue to melting her ankle.

“Voila!” Evie exclaimed suddenly, as she pulled her hand away, disembodied foot with it. “See, I purposely melted my ankle so that-“

“No, yeah, I get it. Great, so you severed your foot, so what?”

Evie continued to rub her foot in her hands, slowly wearing it down into nothing but a blob. “Well for one, it feels like an actual massage, plus the melting. So that’s nice. For another…”

Jessie let out a yelp as she leapt onto the floor to dodge the incoming projectile. Two soft splats were heard, one of the remains of Evie’s foot hitting the side of the tub, and another of Jessie as she splattered across the floor. “Are you crazy!” Jessie yelled as she tried to stand up, failing to as she slipped on her own splattered flesh. She settled for a sitting position.

Evie giggled. “What?”

“What if you had actually hit me? Who knows what would happen if we mixed?”

“Oh relax. I’m sure they’ve thought of it. There’s no way they’d set this up if they didn’t have an idea of what to do.” Evie said, crawling her way on all fours to where Jessie sat, cross-legged on the floor on a small puddle of herself. As she approached, Jessie tried to scramble away, but soon found her back melting up against the wall. “And if not, they’ll have to have some way of fixing it eventually so they can actually use this thing. So either way, we’re safe.”

“So let’s have some fun!” Evie exclaimed, suddenly leaping at Jessie.

Jessie quickly fumbled to the side to dodge Evie’s lunge. As she splattered and slid across the floor, she managed to scramble to her hands and feet to see Evie slide face-first into the wall of the tub. As Evie peeled herself off the floor, Jessie couldn’t help but stifle a laugh at her smushed up face. Evie tried to talk, but couldn’t get anything intelligible out due to the lack of a real mouth.

“That’s what you get” Jessie laughed.

Evie visibly shrugged as her hand darted up to her face and rubbed, melting the rest of it away. She flung the excess flesh that used to be her face down into the puddle below her before climbing to her feet and stumbling out to where she thought she heard Jessie, hands outstretched.

Fortunately for Evie, Jessie couldn’t keep herself from laughing. “You’re like a zombie!” Jessie guffawed as she dodged around the tub to stay away from Evie, “A melting, faceless zombie!”

“Whoops!” Jessie suddenly exclaimed, suddenly losing traction on the slippery floor and falling flat on her back. As she struggled to get up, she realized she was too far melted and stuck to the floor. Evie, possibly hearing this, clambered her way to Jessie.

“No, Evie, seriously, don’t, we don’t know what will happen…” But her cries fell on deaf ears as Evie’s hand poked Jessie’s side. Elated to have found her mark, Evie pumped a fist into the air, and started pawing at Jessie’s body, feeling for something.

“Evie, stop! That tickles!” Jessie laughed, as Evie grabbed her hand by the wrist and pulled. Jessie’s eyes widened as Evie yanked her melting hand clean off her arm, and followed suit with her other. “Oh god, you really are like a zombie, you’re even tearing me to pieces.”

Jessie did not know what Evie wanted with her disembodied hands, but she did not expect her to press them up against her melting breasts. “Oh.” Jessie squeezed lightly, enjoying the feel of Evie’s melting flesh in her hands. “Soft… are my breasts this soft when they melt too? I’ve never tried… oh. That’s why you’re doing this…”

Evie’s faceless head nodded as she released Jessie’s hands… which were now stuck firmly to her chest, having melted together. Jessie could only watch as Evie’s hands descended upon her head, and after getting a firm grip, ripped it off her neck. “Oh my god! My head! You decapitated me!” Jessie screamed, before realizing she was still okay. As okay as a melting girl could be, she reasoned. As Evie held Jessie’s head up in a dramatic fashion, she recognized that Evie was probably mentally quoting Hamlet. “Very funny.” She snarked. “Can I have my head back please?”

Evie nodded. Jessie swore she could almost see the evil grin on her non-existent face as she did so, however, and she froze in terror as Evie brought her hand up to her face. “No, don’t. I like my face!” Jessie wailed, realizing what Evie was doing. It wasn’t long before Evie had literally wiped Jessie’s smile off her face. Jessie’s eyes darted around wildly, noticing that Evie had only erased her mouth. Jessie wrinkled her nose in an attempt to make sure it was still there. Her eyes widened in horror as she watched it drip off her very face due to the attempt.

Meanwhile, Evie was doubled up in silent laughter. She plopped Jessie’s head down on the floor across from what remained of her body, giving her a great view of the things Evie was about to do to her.

Jessie watched helplessly as Evie reached under her breasts and simply scooped upwards, cleanly detaching her breasts from her chest. She pressed them against her own body, below her own melting breasts, and massaged them in place for awhile, as they slowly melted and deformed under the pressure. Jessie would have moaned if she still had a mouth to do so with. As Evie let go, Jessie’s breasts clung to her body, giving her the appearance of a four-breasted woman.

With that out of the way, Evie reached down to Jessie’s crotch. It wasn’t long before she had scooped out her vagina in her hands. She glanced over to Jessie’s head, her eyes closed in silent pleasure. While Jessie (and Evie) had certainly made use of her new assets, Jessie had refrained from playing with herself in the melting booths, making this the first time she ever experienced anything like this. Jessie silently, and somewhat begrudgingly, noted that it would not be the last. On the other hand, Evie, being a trained veteran of melting, knew all about what she was doing to her girlfriend. Which is why she started squashing, stretching, and molding the pliable pussy in her hands, and why Jessie’s eyes suddenly rolled up to the back of her head, wracked in sensual delight.

Still playing with the little mixed up ball of delight, Evie decided to lie down, draping herself over what little remained of Jessie’s melting body, to melt over her herself. Half expecting her to try to push her away, Evie was not expecting to be met by Jessie’s outstretched arms.

In the fight to pleasure Jessie, Evie had restrained from abusing her own body, so as to not meltdown before she could get Jessie to. That was tossed out the window now, as Evie rolled around the puddle of Jessie’s body, mixing and melting into it herself, as Jessie herself did her best to mix Evie’s rapidly melting flesh into her own.

It wasn’t long before all that was left on the floor of the tub was a thick puddle of flesh. A computer beeped out, “SESSION COMPLETE: COMMENCING DRAINING”. The interior of the tub suddenly began sloping downwards towards the center, where a small drain hole had opened up, and Evie and Jessie were now being poured into.

As they felt the familiar sensation of being funneled into a large chamber, Jessie’s concern over their separation only grew, as she could still feel herself mixed with Evie. As for Evie, she was only just beginning to develop the same concern.

Suddenly, the chamber they were in whirred to life, as another robotic voice rang out “ATTEMPTING SEPERATION”. Needless to say, the word ‘attempting’ was not reassuring in the slightest to the mixed up lovers as they felt themselves begin to swirl around. As they whirled around in the chamber, they felt the cold intrusion of another liquid, which seemed to be water.

After what seemed a dizzying eternity, the whirling came to a sudden stop, as they felt themselves slam against two separate walls of the chamber, and abruptly fell down shafts that opened up below them into a pair of molds.

Due to the dizziness, it wasn’t until they had mostly filled both molds that they realized they still weren’t separated, and that the machine was simply funneling half of each of them into each mold. Unable to protest in their liquid state, they were helpless as their bodies formed in the cold metal molds.

In a few moments, the molds cracked open, and the pair stumbled out, dizzied and confused. Once they had gathered their thoughts, they could only stare at each other.

“Oh… god, what did they do.” Both girls said simultaneously, looking each other up and down. “We’re really mixed up now…” Again, simultaneous. “We’re both sharing both bodies?” they yelled. A hand shot up to each of their heads as they rubbed their temples in frustration.

““Okay, okay. Let’s go talk to the receptionist… maybe she can help us.”” The girls wrapped themselves in towels and went to retrieve their clothes from the tub room. After a brief kerfluffle  over which body would wear which clothes, they headed back out to the front desk.

“Oh, hello, Evie, Jessie!” the receptionist greeted them enthusiastically, “I see everything went smoothly then!”

“”Not at all!”” they yelled. “”Your machine didn’t separate us after we melted together, and now we’re all mixed up in each others’ bodies!””

“Um… you already had the same body-“

“”No! We mean we’re literally both in both bodies! It’s… really disorienting!””

“Can you please not both yell at the same time?” the receptionist winced.

“”Not really, no!””

“Oh. I get it now. You’re literally mixed up…” the receptionist finally realized. “Well… good to know our separation mechanism isn’t working properly… better get the lab guys on that.”

“”What about us!””

“Um… well, sorry, but until we get a fix, you might be stuck like that for awhile.”

“”What!””

“Sorry.”

“”No! Fix this! It’s really, really weird!””

“Look, we can’t. And you signed forms.”

“”I didn’t! Er… Jessie didn’t!””

“Well, you’re both Evie, aren’t you? And Evie signed forms, therefore…”

“”…you’re serious.””

“Yep. Legal loopholes are kind of my business. Look, I’ll call you when we can separate you, but for now, please bear with us. And each other.”

“”But how are we supposed to do anything like this? We’re too in sync! It took us like 10 minutes to decide who was wearing whose clothes!””

“Try… not moving one body, and letting the other use it?”

“”…okay. Uh, so Jessie gets the body with Jessie’s clothes and Evie gets the body with Evie’s clothes. Sounds simple enough.”” They echoed. “”Evie won’t move for now, so Jessie can try to move.”” Then, both bodies muttered, “”This is so weird.””

“…well?”

“Um.” Jessie’s body said. “Oh! I guess this-“

“-works. Damnit!” Evie’s body said. “Jessie, stop using my mouth to talk.”

“It totally defeats the purpo- ugh, now I’m using your mouth!” Jessie’s body finished.

“…wow.” The receptionist said. “You really are in sync.”

“”Duh!””

“Okay, try actually moving. That might be easier. Evie, you walk around.” The receptionist motioned specifically to Evie’s designated body. “Jessie, try not to move.”

Evie’s body took a step forward, then tripped and fell flat on their face. “”Ow!”” they both winced. The receptionist helped them up. “”Okay, so we actually both need to coordinate to move…””

“That’s… more complicated than I thought it would be.” The receptionist said, glancing out the window. “Look, I have customers coming in soon… I’m terribly sorry you two, but you’ll have to sort this out on your own. I’ll call you the moment I hear from our lab technicians, and I’ll submit the report as soon as you leave.”

“I guess we have no choice…” one of them said, “We’ll just try to keep ourselves straight.” The other finished. They left in a huff, walking to the parking lot in perfect sync. ““I think the best way to deal with this is to force some sort of separation between our bodies.”” “Well, someone’s got to drive.” “Not it.” “”Actually… don’t we both have to drive?”” “Oh, yeah.”

Both girls reached for the driver’s seat door handle at the same time. “”Um…”” “Look, I… we have the keys, so we’re driving.” ”That works.” “”Yeah. Uh. I’ll go lie down in the back.”” “Good thinking.” “Yeah, the difference might let us sort out who’s who.” “”I know, that’s why we’re doing it.”” “This is giving us a headache.” “”Two headaches, actually.”” They laughed at their own stupid joke as they started up the car, “”This is going to be an awesome few weeks.”” they both grinned.
