Princess Teresa of the kingdom of Valdora stomped into her room and slammed the door behind her. “Gods damned council!” she shouted to nothing, stalking over to her three sizes too big bed and falling back on it with a loud fwump sound, and then screamed wordlessly into her pillow. This was the sixth time this week she’d been ‘politely removed’ from a meeting of the king’s council in the last week, them saying that a princess doesn’t need to know the gritty details of governance or international relations. Never mind the fact she’d studied more about the issue of the day than any of them, and may have some informed opinions on how relations with the Dark Kingdom should evolve now that it’s lord had died and the title passed to some previously little known child. Why make her study diplomacy and government, and then not let her be involved in diplomacy or government? 

Of course, maybe her phrasing had been a tad crass. She’d learned a variety of colorful swears from her arts instructor, who had a filthier mouth than any sailor. But who’s fault was it she was so annoyed as to use them? These days it wasn’t just about the ruling of the kingdom so much as it was the related stresses of her brother taking the throne and the council debating who she should marry as if she were a prized breeding mare, instead of a person who might want some input on who they spend their life with. Her father had been insistent that she have input, but he wasn’t around anymore. If she were the heir she might get a word in, but she had the misfortune of being born second and her brother already had children.

And to top it all off, she was frankly tired of being forced to be a proper lady. Her maids often seemed far freer than she was; she had to act proper and princess-like at all times, even in her own home. She had to only have princess-y hobbies and interests, even in private, which had led to quite some talking when her instructor had caught her with some more lurid works from the back of the library. This all boiled down to having done the same things, every single day, essentially from the point she could walk onwards. The courtiers and suitors were incredibly dull at best and offensive at worst. She wanted something to happen, anything. 

Teresa heard the door open behind her, and sat up and brushed herself off. It was probably a maid, and that meant she had to be at least a bit presentable. But when she turned around, nobody was there and the door was ajar. “Hello?” she called. “This isn’t funny, whoever you are.” There was a scratching sound on her sheets, and a gentle tug. Then a hand reached up on her bed. More scrabbling, and that hand pulling a small, strange looking creature up onto the bed. “...What?” she said aloud. Before her puzzlement could resolve into a cry for help, or possibly the use of the nearest heavy object as a makeshift mace, the imp threw a cloud of dust into her face.  The princess suddenly felt very… very sleepy…

    Dark Lord Karxon, son of Dark Lord Karxon Senior, was psyching himself up. His servants had managed to capture the princess of the neighboring nation, as dark lords are wont to do. Of course their king would call for adventurers to rescue her, so it goes, but this dark lord wanted to stand out from the crowd! His father might have disparaged his constant studies, but in them he had found quite the ritual; it was customary for the dark lord to summon a succubus as his bride. Why do that, when he could make a succubus bride, and ensure that the heroes failed to rescue their princess at the same time? It was genius! 

    He thought it was at least. His advisors did too, but he knew better than to trust their words on anything. There’s two reactions to a new dark lord: assassinations or cozying, and the advisors were those that did the latter and tried to tell him what he wanted to hear regardless of the truth. Unfortunately, most of the useful demons, dark knights, vampires, and so forth had tried the former. They had been turned into frogs, clothing, loyal but dull imps, mindless golems, and so forth by the traps he set for everyone who thought a physically weak dark lord was an easy target.

    Honestly, Karxon blamed his father for that. He’d never been quiet about his distaste for the heir’s scholarly pursuits and had made them known. But after most of his obvious enemies were taken care of and his plan worked out, he’d have established his right to rule. He just had to get in there, play the evil lord for a bit, and he’d have all his problems sorted and could go back to reading. 

    Which was so simple that he was pacing in front of the door vacillating about his entrance instead of doing it, huh? Dark Lords are not nervous! Especially not about interacting with pretty girls, or turning them into incredibly sexy demons, or anything like that. Shaking his head one last time, he turned to the door and waved his hand. The door swung open as if it had been shoved by a giant, there was some dramatic misting, and the young man strode through in his dark armor that was definitely not a size too big for him, face shadowed by a dark hood with red eyes peering out. “I trust thee have made thyself comfortable, dear princess - thou should get used to thine surroundings, for-” 

    He had this whole speech ready and it was ruined when he stopped dead with surprise. Far from standing and staring in horror from within the magic circle, the princess was seated at a nearby table, drinking tea with a pair of the imps. She looked at him slightly bemused. “...Tea?”

    Karxon stared for several seconds. “Why…? How…? Imps, explain yourselves!” 

    The imps dropped their teacups and saluted. “Sorry, milord! She was very convincing! And very polite about it!” 

    “You let her leave the binding circle? The crux of the plan?” 

    “She was careful not to damage it milord! And promised to go back when tea was done!”

    The princess laughed a little bit at that. “Honestly, they’re very polite, for demons. I take it you are ‘Dark Lord Karxon’? I thought you’d be taller, and less cute.” 

    Karxon sputtered a bit in response. “I, uh, I… yessss?” Wait, cute-

    The princess nodded and stood, shuffled to the side, and curtsied. “Apologies, your grace. I was not sure when you would arrive. I am Princess Teresa of Valdora. A pleasure.”

    The dark lord stared more. Then he awkwardly bowed. “Uh. Same to you. Yeah.” 

    “Now that the pleasantries are out of the way,” Princess Teresa said, smiling sweetly, “Might I ask what precisely you plan to do with me? There’s a procedure for this sort of thing, and you don’t seem intent on cleaving to it. It is, broadly speaking, considered rather rude to kidnap foreign royalty, especially without a plan.”

    Teresa’s prompt offered Karxon a moment to compose himself. “I, uh, yes. I was expecting the ‘what do you want with me’ to be more fearful but that works.” He coughed and cleared his throat. “It is simple my dear! It is a fine tradition in the Dark Kingdom that the Lord’s Consort is of the demon race! As well, I seek to prevent heroes from coming to rescue you! I shall kill two birds with one stone, so to speak, by turning you into my succubus bride!” 

    Teresa stared for a few moments. Karxon was expecting shock, horror, etc. Which honestly he felt bad about but, well, had to be done right? She walked over to him, getting very close and looking at him very intently. An attack, maybe?

    “Does that mean I wouldn’t have to go back?”

    Teresa didn’t know why she said that, but she had. “Does that mean I wouldn’t have to go back?” 

    The dark lord looked confused. It was kinda adorable, watching him process that. “...Excuse me?” 

    “I wouldn’t be rescued because I’d be the corrupted demon queen right? Right?” Teresa asked.

    “Well, uh, lord’s consort, but yeah? That’s the plan?” he managed. 

    “Consort, queen, same difference.” She paused. “How much freedom does the lord’s consort have? Would I be able to do whatever I want?”

    “Unless someone can stop you, yeah. I’m turning you into a powerful succubus, and I’d be the only one really strong enough...” 

    Her gaze hardened for a moment. “...Do you plan to use that power much?”

    He shrunk away under the glare. “N-No… t-technically you’d be my servant, but that’s sorta just on paper, it’s been more of an equal partnership since my grandmother beat it into everyone’s heads…” Dark Lady Lilith was still alive, Teresa recalled. Probably the only dark ruler to retire rather than die on the throne. She made sure nobody forgot why.

    Strictly speaking, Teresa should have been appalled at the fact she was considering it. But really… what was there to go back to? On the one hand, political webs and backstabbing and being essentially sold to keep an alliance or something, nevermind self-repression. And on the other hand, basically co-rulership of a kingdom, a fairly straightforward political system (Less political backstabbing and more duels to the death, to her knowledge) that she might be able to implement some of her own more radical ideas in, freedom to do whatever she wanted if she was strong enough for it. Also…

    “Just checking. Powerful and sexy right?” she asked.

    “Wait, wha-”

    “And still basically myself, right?” 

    “I don’t unde-”

    “Because if the answer to either of those is no then we’re gonna have to negotiate a bit, those are deal breakers and I’m walking.” Karxon tried to speak, failed, and swallowed. Teresa was pressing very close to him, and he seemed very flustered. Which raised another concern. “And you are going to be able to satisfy me right? If I’m a succubus I can’t be expected to go celibate because you can’t touch a woman.” 

    “I, I, w-” he stammered. One of the imps helpfully gave him it’s cup of tea, which he took with a shaking hand and downed in one gulp. “Y-Yes. That’s all accurate, mostly. S-Sexy is a given for a succubus of high rank, and the spell leaves your identity and personality intact, just thoroughly loosens inhibitions.” He paused. “A-As for the other thing, I, uh, I will make it work, don’t worry... “ 

    Teresa frowned. “...Also, I’m gonna have some suggestions for how things are run. You might be in charge, but I’m expecting you to listen.” 

    Karxon nodded, not sure how else to respond. He didn’t mind that, and had kinda planned on it, but well, this wasn’t how this was supposed to go. “I… uh… is that all?”

    Teresa thought. “For now.” She nodded. Honestly, it felt good that she was having some say in what was happening to her now - it was more than she’d gotten before. ...And the situation was, to be frank, kinda hot to her. Which of course she wouldn’t say, yet, but she had the sense that when her inhibitions got loose enough she would say something.

    Karxon took a step back and coughed. “Right… uh, now that that’s, uh, done, could you step back into the spell circle? Carefully?”

    Teresa finally backed off, and followed the instruction. She stepped back into the circle, thinking about what she might want out of this, and how hot it would be, and also kinda how cute the young lord was when he was flustered. “Now what?” 

    Karxon swallowed hard. “You know I feel so much better about this with you being alright with it… anyway, it’s fairly simple actually. It converts your soul into that of a succubus, and your body quickly follows suit. Most of the difficulty is making it change like you want instead of going wild - the human soul is surprisingly mutable. 

    “Does that hurt?” Teresa wasn’t really afraid, more curious. 

    “Well, if you resist it yeah… if you’re uh, willing, then it should feel… uh…” He blushed, unable to say it. 

    “Ah, I see. Good.” She felt a little warm below already. 

    Right. No more waffling about. Time to start. Karxon cleared his throat, and began to channel the spell. It didn’t require any words - the circle played the part of the focus rather than a chant - but it quickly became clear that something was happening, as the chalk circle started to glow pink.

    It felt very strange, to put it lightly. She had already felt rather warm from some moderate arousal, but now the heat felt different - an outside force, the magic of the circle reaching inside of her and doing… something. It’s difficult to describe what it feels like for your soul itself to change. Karxon hadn’t been lying though. It didn’t hurt at all. At first, there was a feeling of pressure, all around her body. But she didn’t resist it. She welcomed it, and she felt a lot lighter than she had ever before. And also… hornier. 

    The feeling was pleasurable, plain and simple. She felt the magic poking and prodding at her, changing her, and it just felt so damn good. She pulled her dress up a bit with one hand in order to have easier access to her panties, and her other hand plunged inside instantly. She moaned loudly as the touch sent a shock through her system, and pressed in. 

    As she started to play with herself, she looked up to see Karxon staring at her slack-jawed. “Hnn… did I…” she moaned a bit, “Did I say you could stop?” she managed. He managed to pick his jaw off the floor and continued, arms out and a red magical energy flowing from his fingers to the circle. 

    The light flared and increased in intensity, and with it so did her sensitivity. Teresa’s fingers only got more vigorous as it felt better and better, but despite that she simply couldn’t reach the finish. Her clothes felt hot, stuffy, wrong, and so she hurriedly tore them off of herself. If she were less focused on her own pleasure she might have wondered how she was strong enough to do that, or maybe been a bit more gentle so she could reuse them, but she was sure there was plenty of clothes that would fit her new sizes for later.

    It was good she discarded her dress when she did; it was about then that her breasts started to grow in size. She had always had a modest bust before, but that was evidently not going to be the case for much longer. Even as she brought a hand to her chest, it began to glow faintly and grow. The soft flesh quickly filled her hand, sensitive despite it’s size and providing another avenue of pleasure for the changing young woman. In what must have been only a few seconds, but felt much longer to Teresa, she was going from a small B to a generous D in size. While she was never ashamed of her small breasts, she felt an intense pride in the new feeling of weight on her chest. 

    It wasn’t even close to done. She felt herself forced to shift her posture and pose as her figure changed, hips flaring out and waist narrowing, her ass growing nearly as quickly as her bust. She reached a hand around to take a nice firm grip of it, and groaned from the pleasure of it. “Ahh… so good…” she moaned, watching to see how master- how Karxon, she corrected herself, was reacting. And well, he was focusing on the spell, or trying to. He seemed to be having difficulty not being hypnotized by her change. Which to Teresa’s own surprise, she was quite happy about. She was certainly putting on a show, and one that she could tell (from a glance down below his hips) that he was enjoying. Well, if they were going to be together, it was just as well that he enjoy this sight~

    She hadn’t really noticed when it happened, but she supposed the mental changes must have come first. Which made enough sense given it apparently started at her soul. But all it really seemed to do was throw her sexual inhibitions out the window (hence enjoying the fact that Karxon was watching her masturbate) and occasionally thinking of the young man as ‘master’, although on examination he had kept his word and there was no actual compulsion in the magic. An honest dark lord was a rare thing, but definitely one she could work with. When she was done with her efforts to masturbate her own brains out, that is.  

    She had at some point ended up on the ground - the pleasure was too much, and her knees buckled and she fell into a sitting position, still masturbating and making sure Karxon (and the imps, for that matter) saw every little bit of her. As she was touching herself, she noticed her skin around the extremities had changed color from pale peach like she normally had, to a more aggressively pink tone. This caused her some pause. Maybe…

    “H-Hey… master…” Teresa said from her position in the circle. Karxon blinked, his concentration diverted for a second to the girl. She already had the succubus figure, and the change was now more about giving her a distinctly less human body, which was already in progress. ...And she was masturbating vigorously the entire time, which was a sight to see. 

    “I, uh, yes, Teresa?” Karxon managed. Wait, master? Already? 

    “Why pink?”

    What?

    “The skin I mean.” she clarified, “It seems kinda… garish. I’d prefer red. Can you do that?”

    “I, uh, well, it’s supposed to be just turning you into yourself as a succubus, but-”

    “But you can give me some input, yeah? I did agree to this…” 

    Karxon stared. She was being stripped of her humanity, and her concern was not looking overly garish? “I… uh… yeah…?” A lesser mage couldn’t do it, but well… he might not have been physically strong, but he’d had the greatest magic users of history raised from the dead to teach him, so it wasn’t boastful to say he could… “...Yeah.” He made some quick adjustments to the spell, and the pinkening skin started to shade darker away from hot pink to vibrant red. 

    Teresa seemed satisfied with that, masturbating even more as her skin shifted colors. She wasn’t used to succubus stamina - she’d be able to keep going for a while. And even if that wasn’t the case… well, if she was letting the spell have it’s way with her, she’d be rewarded at the end…

    The middle of the circle was a mess when she stood, the less core changes now taking place, like her hair lengthening and a tail budding out of her bottom. “Hnn… mmmh…” she moaned, trying to get something out… “C-Can I make some more requests? I’d like some more requests…” she said. 

    Karxon honestly found it a bit impressive she could still think, having been masturbating for several minutes straight now. So he just nodded.

    “I… I think I want really long hair, I feel it growing but I bet it’s not going far enough… I’m imagining bright pink, like my skin was turning before, and…” She paused for a second, vigorously stroking herself, “Like, floor-length…” 

    “That’s…” 

    “What I want, and what you’re giving me, master.” Teresa finished for him. 

    “...What you want, and what I’m giving you.” Karxon said. He just… couldn’t really stand up to her. 

    Even as her hair grew, she had more demands. “I want my tail to be really mobile and easy to control I think… maybe ending in a heart-” she said, and as she talked that tail grew out. She looked around herself in amazement, flicking it a few times… and promptly brought it around her body and slotted it in where her fingers had been. “FFfffffuck-” she moaned, having evidently not expected it to be sensitive too.

    “Oh, and the wings-” she said, looking over to where they were already growing, “Can I have the ability to tuck those in or move them? I sleep on my back…” It was like she was getting used to the pleasure from touching herself, able to be mostly coherent in speech, if interspersed by some moans. Karxon nodded. At this point, he was mostly trying not to make a fool of himself by having too… intense, of a reaction to Teresa’s show. Sure, she was going to be his consort and they’d… do things… but he was embarrassed! 

    It continued in this fashion with the horns, the long nails, the shapely legs; respectively, she wanted them to be cute and curled like a ram but not too heavy, long enough for attractiveness but not like claws, and not so ridiculous as to force her into a weird walk. Over time, it had shifted away from browbeating and more to cooperation, discussion on what would look nice on her. She was looking almost full succubus now, and Karxon was ready to finish up the spell. Even with his reserves, an hour long ritual took a lot out of him… and so did the fact she had been touching herself for that entire time.

    “One more thing…” she said. “Lust crest. You know, the thing above the crotch that all succubi supposedly have?”

    “I mean… it doesn’t do anything, are you sure?” Karxon asked. 

    “Hell yeah.” Teresa said - she had gotten progressively less refined in speech as they talked. “A princess with a tattoo? Unthinkable. So I wanna go as hard on it as I can. And it’s sexy!” she said, and as she talked a black crest was apparently burned into her bright red skin. She rubbed it and moaned loudly. “Yeah… that’s hot…” 

    For a few moments, they stayed like that. The ritual was in it’s winding down phase… which meant that Teresa’s pleasure was growing. It felt like her whole body was on fire. Once more, her knees buckled and she collapsed into a moaning mess, tail rapidly plunging in and out to pleasure her, hands kneading her own breasts, as finally she could stop being on the edge - as finally she was allowed relief. She shrieked with pleasure as she reached two kinds of completion. 

    The light faded, and Karxon blinked the pink out of his eyes finally. The imps had vacated the room, leaving him alone with the new succubus. After she took a moment to recover, she looked up at him, gold eyes and black sclera staring at him. Then, she grinned. “Well, master, husband… what do you think~?” she said. 

    “...what do you think~?” Teresa asked. She felt better than she had in… well, ever really? Her new form felt so right. And seeing the stiffy that Karxon had, well that just made her feel very attractive in a way she hadn’t before. Karxon found himself unable to speak for a few moments, and mumbled his response. “What was that~?”

    “...Hot.” he said, a bit louder, and blushing beat red. It was around this time that the imps came back in, with a black silk dress that looked like it wouldn’t hide very much at all. They offered it to her, but she waved them off for now. 

    She stood, now the same height as Karxon and looking him in the eye. “Well… is there any formalities here, or do you just… say I’m the queen or something?”

    Karxon pointedly looked away. “I think I just say it… nobody will say no, when they see you.”

    It was kinda adorable. But Teresa knew what she wanted. “If there’s nothing that needs doing first… why don’t we consummate the whole thing, hm~?”

    “Consum-” he started to ask, but he was interrupted by Teresa pulling him into a kiss, sloppy and with a lot of passion and a lot of tongue. She waved the imps away as she started dragging him to the ground right there. 

    “Does this look right, you think?” Teresa asked Malachiel the Imp, as she checked herself out in the mirror. The fine black dress hugged her curves and made sure to show off the goods properly, which she just loved, and was accentuated quite well with the spiky collar and wristbands. She thought she looked great for her first day in court, and her Imp assistant agreed with a vigorous nod.

    It had been a week since she became the Dark Queen (a rename of the “Lord’s Consort’ role to reflect the more equal partnership she aimed for). There had been 4 assassination attempts in that time, the results of which had been the mirror, the dress, the spikey collar and wristbands, and Malachiel; she thought she’d feel bad about it, but apparently transformation was a far more common punishment than execution here and to be frank, they’d had it coming. 

    She walked out of the dressing room and down the short hall to the court, where Karxon waited on the throne, trying to look imperious but mostly looking uncomfortable. When her tail wrapped around his hand, he looked at her and seemed to relax a bit with a smile. They had met only recently, but after the first twenty four hours of sex had discovered quite a number of shared interests, particularly those scholarly in nature. Even if she hadn’t turned into a demon, she was quite certain they’d have been into each other anyway. She took her seat in the slightly smaller throne at his side. “Ready, love?” she asked. 

    “No.” he admitted, “To be honest, I don’t really know how this works… dad mostly just looked at them and decided whether to give them the request or execute them for wasting his time without actually listening.”

    “I’ve sat at a bunch of this kind of stuff.” Teresa said, “I’ll help you through it.” She clasped his hand in hers, and gestured for the guards to open the large door. “Court is now in session!” she shouted, echoing down the halls.
