“So what’s the catch?” Tom asked.
Vi furrowed her brow, orange eyes glaring at him. “What do you mean? This isn't a scam.”
He raised his hand to indicate their surroundings. The kitchen of the apartment was less than ten years old and had appliances that looked like they just walked out of a catalogue. It was clean, there was no deathly racket from a heavily trafficked road or railway, and there were no bullet holes in any of the windows.
“This is way too good for the rent you’re charging. Something’s gotta be wrong.”
She laughed. It was a pleasant sound, despite her menacing appearance. Her skin was dark red, with glowing orange tattooed chains going up her body, ending at a pair that wrapped around her wrists. Her horns added half a foot to her 5’8 height, making her technically taller than Tom. She looked every bit the scandalous seductress of many a cautionary tale, though this effect was blunted by the fluffy pyjamas with little pictures of white whales and a metal band T-shirt.
“Oh, I see. Just because I’m a demon means I’m trying to snare you into some kind of Faustian pact?”
“No, no, that’s not what I meant! I have plenty of Infernal friends.” At the eyebrow she raised, he clarified, “Sorry, that slipped out. I’m not anti-demon or anything. I’m just naturally suspicious. It’s impossible to get affordable housing in this city.”
“That’s fair. I was just teasing you. Yeah, this place isn’t bad. Previous owners gave it to me for a song after I dropped some gold medallions I’ve been saving since the 1500s. But...there is a slight...complication that makes my asking rent so low.”
Tom visibly choked down a ‘I knew it’ before nodding for Vi to continue. The kettle whistled before she could explain. Vi took her hand off the heating element, shaking off the last few embers of pyromancy, and poured two cups. She took them both, teabags added, to the kitchen table. A warning gesture let Tom know both were too hot to touch yet for human hands. Vi steeped the bags of shimmerroot before continuing.
“You may have heard that there are many varieties of demon. Some have special gifts that allowed us to perform our work, before our Chains were broken. Mine is a transformative aura that permeates the area immediately around me.”
Tom blew on the cup in front of him. “This isn’t one of those things where I’m driven mad, is it?”
“Not anymore, no,” Vi said with a straight face. After taking a sip of tea, she laughed at his horrified expression. “Sorry, I just really enjoy winding humans up. The aura is malleable. It’s transformative in nature, but what you turn into is up to me. Brief encounters are fine, I can hold myself back. But if you chose to live here, your physical body would slowly alter. The longer you’re exposed, the more alteration occurs.”
He looked down into the cup. The reflective surface offered a glimpse at his appearance. Curly blonde hair slid halfway down his forehead. He’d have a decent jawline, though he was getting on the pudgy side due to his unhealthy eating habits lately. Working overtime to get the money for a new apartment had eaten into his ability to cook for himself, leading to a lot of late night pizza runs and burger lunches. Not a hunk by any means, but he didn’t look terrible. Well, objectively, he didn’t look terrible. He wasn’t a fan of himself. But everyone hated their own reflection, right?
“Turn me into what?”
“Your ideal self, of course,” she said as if it was the most obvious thing in the world. “I can’t set it to Not affect you, not until you’ve built up a natural immunity to my magic at least. That ought to take a few months. But if you have to change, why not change into something pleasant?”
Tom tried to picture what his ideal self would look like. He pictured actors, bodybuilders, the kinds of guys that guys are supposed to look like. None of it quite fit. The idea that he might get fit without having to work out or eat healthily sounded awesome, though. It couldn’t hurt to try.
“And after that time is up, I can go back to what I look like before?”
She nodded as she sipped, steam sliding up her cheeks. “You bet. The only way to make it permanent is with a Seal. So long as you don’t get scalded with any Enochian binding spells in the near future, consider this a fun little adventure. I promise to help, if you need it.”
Tom chewed over the idea. In the end, he picked up the cup of tea and clinked it against Vi’s own.
“You got yourself a roomie.”
***
The move-in hadn’t taken long. Aside from his clothes and his computer, he didn’t have much to bring. The breakup had been difficult, and his partner had gotten everything. Even the couch. He’d loved that couch.
Unbelievably, Vi said that she had enough furniture to cover him. He got a bed, an end table, and a chest of drawers for his clothes. They were all made of a strange, black wood that reminded him a little of those petrified forests he’d seen while on road trips with his family back when he was young. The mattress, however, was nothing so unique. It was sturdy enough to support his back while balancing out the softness so that he didn’t feel like he was sleeping on a wooden board when he turned in for the night. The only thing strange about it was a dribbling of candle wax around the edge of one of the corners. But, if Tom had to be honest, it was nowhere near the worst mattress he’d ever slept on.
He looked one last time in the mirror, making a mental check of everything he had. He took a picture with his phone as well, to remember if he needed to tell Vi to adjust his appearance. Sleep came easily after an arduous moving day. His last thoughts before drifting off were speculating on just what his ideal self would look like. No matter how hard he tried, he couldn’t quite see who that guy would be.
***
Tom’s eyes cracked open on the morning of the first full day in his new place. He took stock, feeling up and down his body for changes. He half expected to have exploded out of his covers with muscles. Nothing so obvious, but he did feel rested. That was a pleasant change after months of miserable nights spent ruminating and fitful sleep in a bed with someone drifting apart from him. He sauntered over to the shared bathroom for his morning routine, wearing nothing but his boxers. As he put his toothbrush to his mouth, he caught sight of his reflection in the mirror.
“Wha da fwu?!” he screamed, launching toothpaste everywhere. A knock at the door jolted him out of his stunned stupor.
“You alright?” Vi asked from the other side.
“My eyes! They’re...red!”
“Not enough sleep?”
Tom opened the door, then turned back to the mirror to show what he meant. Vi turned his face back to her and examined his eyes with her own. His bewildered expression held a pair of bright crimson irises.
The kind you’d find on a demon.
She leaned up to examine them, tilting his head down with her hands to get a good view. “Looks like you’re changing alright. Though it’s not usually the eyes that go first.”
“Why are they red? I thought you were turning me into my ideal self?”
She shrugged. “I don’t choose what your ideal self looks like. Maybe you want to look more...demonic?”
Tom searched his feelings on that. He definitely appreciated Vi’s looks. But the idea that his subconscious self wanted to look like her confused him deeply. He wasn’t some kind of demon fetishist!
His new eyes widened as he realized how weird this might make him seem to Vi, specifically. Her new roommate’s body changing to look more like her felt like some kind of boundary-crossing that he couldn’t articulate. He stumbled through a series of verbal false starts, unsure whether he should be mad or apologetic for what his subconscious was doing to him. But she put a hand on his bare shoulder, and his stammering halted.
“It’s okay. I’m not offended or anything. They look cosmetic, at least for now. Doubt they’ll give you The Sight. Small mercies; lots of wild shit beyond the veil. How do you feel otherwise?” she asked.
He took a moment to calm himself, realizing he was in his boxers in front of someone he’d only met a few days ago. “Aside from the shock...I feel pretty good,” he turned to the mirror once more, looking at the rest of his body. He could see that he’d lost some weight while he was sleeping. The body hair on his chest had faded to wisps around his sternum. Also not a big deal. He hated having to shave constantly ever since he was a teenager. The only real outlandish change, so far, was his eyes.
“Alright. Keep me up to date if there’s anything else you’re concerned about. I’m sorry you have to go through this, but...yeah. Can’t really help who I am.”
The moment she’d said that, he felt this burst of empathy in his chest. Like he could feel the ages of lament that those words concealed. Tom turned around and hugged Vi. He squeezed her gently, though not quite knowing why. He just felt the impulse to reassure her. To let her know that what it was alright. And that he was alright. He broke the embrace, almost as surprised as she was that it had happened.
“Sorry,” he said. “You just...sounded like you needed a hug.”
Vi rubbed her shoulders, as if feeling the imprint that the hug had left. “I didn’t mind it. Heaven, I kinda liked it. Not too much casual affection in my life now that I’m on Earth. Appreciate it.”
They shared a smile, then went back to their morning routines. Tom finished brushing his teeth, though he couldn’t drag his eyes away from the peculiar pair reflected in the mirror.
***
Days dragged by. He tried to stay out of the house while he job hunted, but Vi told him that would only make the process take longer. He’d always have to come back to sleep, after all. He was a passenger on this journey. All he could do was watch as every day, his reflection changed just a little.
Some of them were great! His appendectomy scar was gone, as were any miscellaneous nicks he’d received over the years. His hair, receding in places despite not being out of his twenties, came back in full force. And not only did he have more energy, but he was stronger. Even though it looked like his muscle mass was shrinking, his ability to lift objects or do push-ups only increased. He exercised just to marvel at the feat of not getting tired after ten crunches.
Other changes were less welcomed. His hair hadn’t stopped at growing back. Its growth had accelerated, darkening to a brown colour as it poured down his head by half an inch every day. He’d quite liked his natural sandy blond and was sad to see it go. As the hair on his head exploded, the rest of it below his neck had vanished. Running his hands down his legs and arms was an interesting if unsettling experience. Indeed, his bare skin was a lot more sensitive to the touch. Stubbing his toe shot wild bolts of pain through him that he had to bite down a scream to hold back, while washing himself in the shower had developed into an inadvertently erotic activity. Somewhere between the warm water and the gentle, slow circle of the washcloth or hand left him choking back an entirely different noise altogether.
And that led into another primary change, one he wasn’t sure he liked or not: his libido had shot through the roof. Where he’d be content to go days without fantasizing or even thinking about sex, he was having a hard time keeping the tabs of his browser from overflowing into salacious content of every description. He detailed every change he’d experienced to Vi except this one. She was already a woman sharing an apartment with a guy. Telling her that he had to masturbate three times to get his dick soft enough to not look like a pervert walking out of his room to make breakfast sounded like a terrible idea. He didn’t want to look like one of those gross guys who couldn’t keep their hands to themselves around demons.
Tom didn’t want to be THAT kind of guy.
He was cooking dinner when Vi arrived home. She set her purse down on the cute little breakfast nook table and her keys in the shattered upturned horn that was mounted on the wall.
“What a day!” she said. “What’re you making? It smells great!”
“Pasta Al Fresco with a little bit of that habanero chicken you like,” he replied. Removing his apron, he scooped out portions for the both of them and placing them on the table. The last few weeks had been...interesting, but he was beginning to come to terms with the changes. The purple skin had been his next surprise, but the only person who saw him was Vi. She coached him through it, watching the amethyst spread until it had taken over his entire body.
Vi slumped into one of the chairs with chicken in front. “Tom, dear, thank you. You’re a lifesaver.”
“Anytime, anytime.” He sat down with his own and they dug in. Some masticating later, he sensed an opening for some table talk. “So...I was wondering what you did before. In Hell, the whole aura thing. If that’s okay?”
She swallowed a long noodle before responding. “Oh, right. Umm...it’s not really good conversation for the dinner table. I was Chained, I did what I had to do.”
“Right, right. That’s okay. Again, don’t have to say anything if it’ll make you uncomfortable.”
Silence held sway for the rest of dinner. Tom hoped he hadn’t put his foot in something by asking about her past.
“Any changes lately?” she asked as they cleared plates.
He poked a pair of bumps on his head, moving his hair out of the way so his roomie could get a better look. “I got these this morning. I think they might be horns.”
Vi took a gander. Sure enough, two nubs on his forehead had broken through the skin.
“Do they hurt? I was born with mine so I don’t really know.”
“A little? It’s more itchy than anything. I still don’t get why my ideal self is a demon. That’s...that’s why I was asking before. You sure it’s that? You sure my inner self is some kind of twinky demon?”
She grinned. “You have slimmed out a lot. Well, in most places. Your butt’s still decent.”
Tom blushed. “Thanks? I guess? But how does it work? How does it know my ideal self from, say, a passing fantasy?”
She ignored the obvious question of ‘you have fantasies of being a demon?’ to her credit and tackled his query head on. “The self is not something that can be denied, nor is it something that can be faked. Human bodies are imperfect vessels, formed by biological happenstance and environment as much as who they truly are. It’s difficult to explain for someone without The Sight to understand, but we all have a deeper, truer self image. Our soulself. Sometimes they’re close to how others see us, and sometimes…sometimes they’re far removed from how our physical bodies appear.”
“The Sight….wait, you said you had that, right? Can see what I’m turning into?” he asked.
“I could tell you,” she acknowledged. Vi closed her eyes, and when she opened them again, they burned with heatless flame. “But that would ruin the fun, wouldn’t it?”
***
“Okay Vi, something is definitely wrong.”
The demon looked up from her laptop. One month in and Tom’s old clothes hung limply off of him, like they were hand-me-downs from an older brother. His horns now curved over his hair, sweeping back like two adorable sickles. He’d lost a lot of the belly that’d he’d had when they first met. Some of that had redistributed itself, however, moving to his thighs and hips instead. He was shirtless, so she could see the hairless chest that he was pointing to.
“What’s the matter? I think you’re looking swell.”
“I’m growing TITS, Vi!” He pointed at his nipples, indicating an itty bit of mounding.
She squinted. “You sure those aren’t just tiny pecs?”
Tom laughed bitterly. “Yeah, pretty sure. Cause as those get bigger, my-“ He cut himself off mid-sentence, blush arising on his purple cheeks.
That made her close up the computer. “Oh dear. Is something else getting smaller? Something rather important?”
His blush deepened. He nodded, but he didn’t look her in the eye.
“I see. I knew there were some humans like this, but I’ve never met one in denial before.” She stood up, picking up his hands into hers and squeezing them sympathetically. “It’s okay, sweetie.”
“Denial of what?”
Vi offered a wan smile. “Any idea why your ideal self would have feminine characteristics?”
Tom yanked his hands from hers. Decades of mental armour meant for self-defence slamming into place. “That’s bullshit. I’m not...no. no, this is some kind of trick. You’re a demon and you’re tricking me into THINKING that I want to be a girl. Is this a fetish for you? Is this how you torture people?!”
The smile on the demon’s mouth faded. “That’s...not a thing. Why would we punish someone for wanting to change their form? It’s the Other Side that wants bodies to be immutable.” The minor bout of outrage she had experienced at being accused gave way to genuine sympathy. “Oh, Tom dear, did you really not know?”
He sputtered, trying to come up with a logical reason behind this. He had to be dreaming this all, or there was a mistake! How could his ideal self be a woman? How was that even possible?!
He’d asked himself whether he was trans lots of times and always the answer was no. There were many reasons, and he’d gone over them so many times that he could recite them from memory. No, obviously, because he liked male-coded things that women couldn’t possibly be into. No, obviously, because he didn’t know from an early age or crossdress (more than a couple times that didn’t count). No, obviously, because that would mean he’d been lying to himself and that strange twinge in his chest when he saw a cute outfit or heard someone else get called a pet name wasn’t some aberration.
He must have looked like a short-circuiting automaton, because the moment he snapped out of his digressive thought, Vi had him wrapped in a hug.
“It’s okay. You’re okay. It’s okay to be-”
The iron door in his mind slammed shut before she could finish the sentence.
“No.” He pulled out from the hug. “There’s something wrong. There’s...I don’t...there’s something wrong. I can’t do this.”
He shuffled back into his room and locked himself inside. When he was sure he was alone, his back slid down the door and cried. He cursed his weakness. He willed himself to stop sobbing. But much like the rest of his body, it was no longer under his control.
***
The changes didn’t slow down after his conversation with Vi. If anything, they increased. His hair moved from brown to an unnaturally black colour that pulled light from the air around it. His miniature breasts grew in size until they reached a tiny handful, then stopped. They were incredibly sensitive to the touch, though Tom tried to brush against them as little as possible. He banished anything but the loosest shirts from his wardrobe, at least for the moment. He also went bare chested on occasion, something he felt increasingly uncomfortable with doing. Vi had offered him a bra, but putting it on left him buckling and his hand clamped over his own mouth to keep from crying out from the mix of pain tinged with an unmistakable spike of pleasure.
It wasn’t just his growing tits that were sensitive. It was like his whole body had become a live wire. Even feeling a breeze from a fan on his skin was getting to him. He sat on his bed, scrolling through information about demons on his phone. How their bodies work. How their magic operated. His room was sweltering, but he dared not open a window or turn on a fan. Sweat poured down his face, tingling his pores and making him shiver. None of that mattered. There had to be some way of figuring out what was Really happening to him.
Tom had talked with Vi a few times after his blowup. He’d calmed down, but he refused to acknowledge that his ideal form might be female. Their exchanges were terse and one-sided. He felt like an asshole. He didn’t want to be mean to Vi. She’d told him, up front, what was in store for him if he chose to stay there. This couldn’t be what it seemed. It was just a fluke. He just had to wait it out, like a magical fever. Then he’d have a super-cheap place to live and a hot roommate.
And Vi was hot. So hot. Tom imagined her in front of him, naked and horny. Her blazing orange eyes. Her confident smile. Those tits...His diminutive member rose to life, poking at the fabric of his underwear and reminding him of how much size he’d lost. Barely three inches there now, down almost half from his original length. It felt like he’d retained the same amount of nerves, however, and it was difficult not to give into his urges and start stroking off right there. He gave his stiff member a few cursory squeezes through his boxers.
“Oooh,” he moaned. Moaned. It sounded like the kind of exaggerated noise you’d expect in a cheap porno, and it had come unbidden from his mouth. What was happening to him? What was he becoming?!
Three knocks on the door shot him to his feet. He’d been locking it more often than not, so he needed to walk over to the door. Before he did, however, he realized he was essentially naked save for his boxers. His smooth, purple skin still looked otherworldly, and he’d needed to cinch up the little strings on his underwear to keep his pants from falling down as his size bent to match new proportions. His erection was still visible through his underwear, but it rarely if ever went away these days. He decided to just hope she didn’t notice.
Tom opened the door a crack.
“Hope you don’t mind me checking in on you,” Vi said. There was genuine concern in her voice. He gave a shaky nod.
“I...I think so. The changes have slowed down, as far as I can see. Though I still don’t understand...I look like...” He couldn’t say it. The words lodged in his throat coming out.
He looked like a girl. A cute demon girl, to be precise.
“Can I come in?” Vi asked.
Hesitation, but eventually he accepted. There was nothing in there that she likely didn’t know already. The room was dark, smelled of sweat and Tom’s unwashed body that was starting to smell feminine too. Whatever hormone balance that was in charge of that swinging hard, making his transformation almost complete.
She sat down on the bed, hands running through her hair. Tom joined her, leaving a little space in between.
“I’m sorry I put you through this. A lot of humans enjoy the changes, and I thought you would too. But when you have feelings buried under the surface...”
His old reflexes triggered. “I don’t have...how can I be...not a guy?”
“Do you like being a guy?”
“Of course!” he responded without thinking. When all he got was a quizzical look back, he amended his statement. “I mean...it’s not really something I put a lot of thought into. I don’t want to be a guy, I just am a guy.” He indicated himself with a sweep of his hand, but his body didn’t look particularly masculine at the moment, so his point that he was obviously male was somewhat lost.
“You ever have dreams about becoming a woman, or fantasize about it?”
A long, long list of questionable pornography choices rolled through his head like a montage of evidence presented at trial. “That’s different.”
“It’s not. Men don’t wish they weren’t men.”
“That’s...that’s...” The sea of emotions roiled in his mind. He felt like he was about to burst again. He clawed control back with anger, springing to his feet. Tom’s body shook, his adrenaline spiked as if his life depended on the next few moments. He sputtered out responses, excuses, each dying in his mouth before he could give it voice. He waited for a coherent response to form. A roar of defiance. A statement of outrage at this terrible fate. Anything! But it never came. Tom’s mask fell, slipping through his fingers like mist.
He, whoever he was, settled back into the mattress. “Oh. God. I’m not a guy? I’m not a guy. What the fuck do I do now?”
The first thing Vi did in response was hug her close. She didn’t break free from this, instead leaning into the embrace. She needed this. She needed this bad.
“Well, what do you want to do? If you’re going to be a demon, the first thing you have to learn is that you cannot operate on someone else’s commands. You have to choose for yourself your path. All I can do is help.”
She nodded, though she didn’t feel any clearer. “Well...Tom’s not right. I don’t feel like a Tom. Not very demonic at all. What are demon names like? Is Vi your full name?”
“It’s Leviathan,” she said, then shrugged. “I know, I know. It’s a bit of a mouthful. Vi fits better on coffee orders.”
He picked up his phone from his night table and scrolled through the entries on Vi’s real name. “Oh...what if my name was Tia? Like Tiamat?”
“I love it! I knew a Tiamat once, but I’m sure you’ll be a much better dancer,” she said. Her eyes caught sight of a peculiarity. The obvious bulge poking out of Tia’s underwear. “Looks like one place stopped transforming.”
Tia grabbed the blanket and covered herself. “Fuck, fuck, I’m so sorry. It’s inappropriate, I know. We’re just roommates.”
Vi wrapped her left arm around her roomie and moved the blanket out of the way with her right. “You look cute too, y’know. Don’t think I never noticed the noises you made while you jerked off. Demonic hearing is very good.”
Tia’s face would have turned scarlet had she still had her human pallor. Instead, it was more of an eggplant colour as she cupped her face in her hands. “Oh fuck...I’m so so so sorry I didn’t-“
“Shh...you think I’m not as horny as you?” Vi asked. She stood, shucking off her clothes and revealing the sight that Tia had been fantasising about since they’d met. Though she certainly hadn’t added one special detail in her lurid imagination.
Vi had a cock too.
She stroked her massive red prick to life, though it was clearly already half-awake. It had at least two inches over Tia’s cock before she started to transform, making it more than double her current armament. The transformed human gulped at the sight. She’d never had an experience with another person with a cock before. She didn’t know what to do! But it wasn’t a turnoff. Far from it, the sight of that firming dick matched Vi’s personality perfectly.
“Demons are sexual creatures, Tia. It’s fine. There’s no shame in it. Show me how you’re feeling. And be honest.”
It felt like something burst as she let her thoughts go in a rush. “Oh God oh fuck I’m so fucking horny,” Tia wheezed, throwing herself back on the comforter. She writhed, hands groping her breasts and shrunken dick through her underwear, making uncoordinated pawing motions. The heat. The need. It burned in her like a furnace.
“It’s the heat, right? That fire in your body? You get used to it.”
The bed jostled. Vi straddled Tia, the fresh demon moaning as her wrists wrists were pressed into the bed. The demoness’ strength incredible even after the boosts to Tia’s own. Not that she wanted to break free, of course.
“Tia. Sweetie. How about we take your new body for a test drive?” She slid one hand down, keeping both of Tia’s pinned in the other. With a single, casual display of strength, she tore the boxers off Tia’s body.
“You won’t be needing those anymore, I’d imagine,” Vi said, and leaned in for a kiss. Tia gladly reciprocated, feeling a tingle as their lips touched. Even kissing was better as a girl! When she pulled back, the woman on the bottom felt that familiar uncertainty arise.
“Do you really want to sleep with me? I...I don’t want this to be pity sex or anything.”
Vi laughed. “There’s nothing to pity. Those days are over. You, dear, are a source of envy. Of desire. You are a beautiful woman. And to my Sight, you always were. If you’d like to have some fun, I’m on board. But if you’d rather wait, I-”
“No no no no no can’t wait, ungh, fuck~” Vi’s hand drifted lower to cup her partner’s junk gently, causing a gush of fluid to spurt from the cutie’s little package. Vi coated her fingers in the release, noting that it was the perfect consistency of a lubricant. How convenient. “Ah~ There’s…there’s so much! Why is there so much?”
“Horny girls get wet, silly. They need to be drained,” Vi explained. Before Tia could say anything to the contrary, Vi had her finger pressed up against her roomie’s ass.
“W-what? Ngh...but...” Tia managed in between inarticulate moans. Those only increased in volume when Vi plunged her finger inside, using a practiced motion to lightly brush against the other woman’s prostate. Another spurt of watery pre slid out and down Tia’s diminutive ballsack.
“Wow, you ARE pent up. A whole lifetime of being in the wrong body will do that. We might need a bigger tool to get all that lust out.” Vi spread out her roommate’s legs, sliding herself in between them. She let her enormous cock flop down, the size comparison almost laughable. It was like they were two different organs. Tia’s gaze made it clear, however, that she had a hunger for one. That she yearned to be split by something so powerful yet so indisputably feminine. Vi guided her tip to press against Tia’s tight hole, allowing the steady flow of fluid from her partner to do the rest of the lubrication.
Tia knew what was coming. She’d had the occasional curious moments of playing with her ass in the shower. But this was far and away more than she’d ever done! But something told her it would be okay. She gave Vi a nod and braced herself.
Vi sighed as she slid in. Tia’s ass being a lot warmer than the recent human bodies she’d been used to. Demon sex was often literally hotter than human sex, after all. She only got a few inches inside before Tia’s muscles strained against the intruder. Against this strange, alien sensation.
The dominant demon cupped her submissive’s cheek. “Relax, Tia. It’s okay. Relax.”
Tia did her best. The strange feeling didn’t go away, and it took her a moment to find the muscles she needed. But when she did, it was heavenly. Giving in felt natural. Felt right. Vi sunk in deeper, and the diminutive demoness groan sounded feral, almost animalistic. She was sating a need she’d never known she had until now. The handful of other partners she’d had hadn’t felt this good. Even her last girlfriend, there’d been something missing in their sexual compatibility. This. This had been it. She was using her cock all wrong. It wasn’t for inserting, it was for stroking while she got enormous slabs of girldick shoved deep, deep inside.
Vi’s pace was slow at first, but that didn’t stop the seemingly limitless flow of juices from Tia’s nub. She moaned, uttering profanities as the bliss strode close to the limits for her still hypersensitive body. Her squeezable tits jiggled with the impact, sending more overwhelming sensations to her overloaded nervous system. Tia momentarily ignored her cock in favour of gripping both breasts, squeezing them and getting every last ounce of enjoyment from this altered form.
It had only been a minute, but this had been the best sex she’d ever had by far. It was partly because she’d been in the wrong role. She was born to be a submissive. But she was also born to be a woman. Everything felt right. Tia felt whole.
“What happens if I were to move away?” Tia asked.
Vi paused her thrusts. “Ngh…fuck, sorry, what?”
“The changes, do they revert?”
With a lot of the blood normally in her brain inflating her dick, it took a moment for the thoughts to register with Vi. "They’ll take a while to fade, but outside my aura, the changes’ll be temporary yeah. Why?”
Tia nodded. “I want to make it permanent.”
For the first time in their relationship, Vi was the one dumbfounded. “Nobody’s ever asked for that before. I’d always done it...to punish.”
Tia spread out her arms and legs over and over like she was making a snow angel. “Do you see this? I finally feel free! Like I’ve been wearing the wrong size shoe for years and I finally get my measurements right. Please, at least for a little while, let me keep it?”
Vi nodded. Her fingernail sparked into orange light, the same colour as her eyes, and she dragged it gently along Tia’s taut tummy. Letters in a language whom no mortal could speak lit up as they appeared in full, forming a circle of concentric letters. When she was finished, the whole thing glowed on its own in an ominous red.
“There. That will hold for a month or two away from me. But if you want a stronger hold, we’re going to need some energy.”
“Energy?” Tia asked, rubbing the strange glowing tattoo. It didn’t hurt. Rather, it felt like a pleasant warmth. “I don’t know if I have any of that to give...I’m not very magical.”
Vi smiled. “Oh, I vehemently disagree. Anyone can be magical! But in this case, we’ll be needing a powerful emotional catalyst. Like, say, perhaps...an orgasm?”
Tia’s breath caught. She spread her thighs wide, showing off her still gaping ass.
“Then do it! Fuck me! Make me a girl forever.”
No encouragement was needed. Vi shoved in her red cock right to the deepest point she’d reached. Tia’s ass was perfectly accommodating. It occurred to her, briefly, that she’d probably need to ask her subconscious at some point why her ‘ideal self’ had an ass that could be easily trained for anal, with a cock that dribbled fluids perfectly suited as lube.
Vi felt it stretch out her ass and press against her over-engorged prostate. Colorless cum immediately resumed its flow out of her adorable dicklet at a steady pace. Wet slapping noises joined the shared chorus of pleasure as they threw away the gentle rhythm and got straight into the hard fucking. It didn’t take long for Tia to feel an at once familiar and strange sensation build up in her body.
“I’m close...so close!” Tia cried out.
Her partner paused. “The moment you cum, that’s it. You’ll be a woman. Or rather, you’ll look like the adorable, sweet, wonderful woman that you always were inside. Are you ready?” Vi asked.
Tia nearly knocked herself out from the whiplash at how hard she nodded. “Yes, yes!”
Vi pressed Tia’s legs forward and dove straight into a mating press, vigorously pummelling her ass and making all that weak cum jiggle and slide. The neighbours were surely aware of what was going on thanks to both women’s voices being unrestrained. Tia’s babbling for more dick and Vi’s atavistic grunts as she shoved her demonic dick farther inside her partner’s ass than the traditional understanding of anatomy would allow. Every motion rubbing against that draining prostate, bringing Tia closer and closer to her climactic end.
“Gonna cum, gonna cum, gonna…aah!” she chanted, body quivering. Vi took the hint and slowed pace, only to make each thrust a hard slamfucking that pounded jets of precum out of Tia’s cock. It took her five swings of her phallic battering ram to break down her walls and make the former human into a demoness for good. Thick spunk shot into her face and open mouth, giving herself the first facial she’d ever received. The orgasm didn’t stop at her waist. It radiated in waves throughout her entire body, finally settling on her belly where the Seal resided.
As the muscles of her ass opened and closed spasmodically with her orgasm, they milked Vi’s prick as efficiently as any pussy ever could. Soon both women were gushing their loads, though the red demon’s cream shot directly into the body of the girl pinned underneath her, filling up her ass with thick, scalding cum that warmed up the body good as it settled in. Being inseminated felt like the most rewarding, most affirming experience she could have felt.
It was done. The energy of both their climaxes slid into the Seal. The sigil on her belly burned white hot for a moment, then settled into a pleasant warm glow. The letters faded into vaguely luminescent tattoos. Tia was busy having the orgasm of her life to notice fully, but as the last dregs of her seed dribbled out of her half-hard cock, she examined the Seal.
“Is it done?” she asked, fingers tracing the path of the design.
“Phew! Huh? Oh, right! Yes, the Seal is complete. So long as you don’t break it with, say, another tattoo, that Seal should keep your form looking like this for a good long while. I can teach you how to sustain it on your own, if you want.” Vi flopped onto the bed next to Tia, who quickly wrapped her up into a cuddlehug.
“Thank you for coming into my life,” Tia said, punctuating the statement with a smooch.
“And you’re not the worst roommate I’ve ever had,” Vi retorted, which got her a floppy pillow to the face. “But seriously...the feeling’s mutual. I know you’re a demon now, but you’ve made me feel at home on Earth like nobody ever as before. Thank you, Tia.”
They cuddled for a while. A light brush of the thigh brought Vi’s cock back to life, and Tia’s own libido never quite vanished even after her orgasm. Soon the snuggle was turning into shameless humping. Vi mounted the other woman again.
“Wanna try a Round 2?”

“C’mon Tia! We’ll be late!”
Vi opened the door, grabbing her purse and slipping on her heels. She looked back to see her new girlfriend, in more ways than one, standing board stiff just inside their bedroom. Her body fit the fabric of her white dress perfectly well, but her body language invoked the awkward girls at their first prom.
“Do we have to go out?” Tia asked, rubbing her elbow. “What if they don’t see me for who I am? What if someone recognises me from before?”
Vi walked over and grabbed Tia’s hands into hers. “You are exactly who you feel you are. Nobody can ever change that. For the record, you look wonderful. It’ll be a fun time! Just a few of my friends from Hell. They’re really cool! Well one of them’s intense but you know how lawyers are. You’re gonna have a great time.”
“You promise?” she asked in a small voice.
“Promise. Upside-down Cross my heart. If you don’t, we can go straight back here for a night of passionate sex and that ice cream with the fudge in it. Sound good?”
Tia laughed. “Deal.”
They walked together to the door, where they shared a kiss before heading out of their apartment and into the hall.
