This had started life as a near 6-8k word long mess. Between sleeping on it and getting help from folks, especially GMJ, I was able to pair this down to just under 3.5k words and focus it better. I hope it entertains.
Nyx opened her eyes and found herself kneeling. Around her body was a magic circle containing runes that told her she had been summoned for the purpose of a contract. She gazed up and saw the one that called her standing in what looked like a bedroom.
It was a girl. Well more of a young woman. Twenty-three in fact. Given name Tanya Roseway. Third year art major with a very strong inferiority complex. Nyx didn’t even need her succubus powers to tell her that much. The way Tanya held herself spoke of a general lack of confidence. With how the young woman’s eyes were glued to Nyx’s curves with a palpable jealousy, it was fairly clear that one of the main sources of her inferiority was of physical lack.
Nyx’s body was built like a muscle MILF. Not massively buff, but clearly strong. Even without her tail or horns, her 6’8” tall body was huge inside the runic barrier and summoning circle she knelt in. Her very presence oozed sensuality and sex.
The poor girl was small, maybe 5’2” at best, with nearly no curves to speak of. To be fair, the short cutey was wearing a nice set of comfy pajamas with a plaid purple, lavender, and black pattern that could have been hiding some of whatever she did have. But even then, it couldn’t have been much.
The jealousy wasn’t the only emotional energy coming off the woman. Lust. Lust in waves. Tanya might be jealous of Nyx’s body, but she was also hungry for it as well. Lesbian or bi? Mmm.
Well, the contract wasn’t going to progress with her just taking stock of things. Nyx finally spoke, husky and honeyed tones were coating each of her words in an arousing sweetness so strong that she could have read the phone book and made this woman cum on the spot. She did not put her all into it for fear that she might melt Tanya’s brain too quickly. They did have business to work out first. “Greetings, Mistress. What desire have you summoned me to fulfill?” Despite saying ‘Mistress’, Nyx felt no actual submission beyond the magic forcing her hand to perform for the woman
“I… Um.. that is….” The woman whimpered and rubbed her thighs together.
“Mistress, you have summoned me. It is a simple transaction. You ask me to do something your heart desires, and I make it happen. Keep in mind, it must be something that can be done tonight.” Nyx was more amused than impatient with her ‘mistress’.
“R-right,” Tanya firmed up her resolve. “I want you to make me a desirable and sexy woman.”
“That’s it?” Nyx was both amused and a little sad that it was such a simple and basic request. “And you do know what I require to perform such a service?”
The woman looked uncertain. “The book said that it just required a sacrifice of some of my magical power, right? Haven’t I already done that?”
“Oh no, Mistress. The meger energy you have made in offering only powered the summoning itself. Let me be clearer: I am a succubus and I hunger. Now, I do not have to be given the offering of magic through sex specifically, though it certainly is the most satisfying option. But a payment must be made for services rendered.” Nyx felt her arousal grow at the idea of spreading this woman’s legs open and eating her out as playment.
The blush that had been warming Tanya’s face since laying eyes on the demon blossomed and burned her whole head and down over her shoulders. “I… um…. that is…” She tried to grasp at anything to distract from her arousal, “Will it hurt? Taking my magic, that is?”
Nyx shook her head, the tone of her voice switching from tempting warmth to a teacher's lessons, “Not at all. Once, ages ago, wizards and the like crafted the exact magic you used to call upon me. But the price for our services would often leave them weak for several days or more. This, as you can imagine, is not a problem for people in the modern era. Few of you realize you even have real magic potential. Only a handful are like you, perform a single spell and before moving on with your life.” Nyx looked around the circle still holding her in place. “Of course, if you wish to summon me or one of my sisters again, you will have to wait till your magic rebuilds. Being that you haven’t exercised or trained in magic much, it could take several weeks. Say the next full moon.”
Tanya, trying to shake off her desire to have this demon spread her legs and just take her already, found herself becoming suspicious. “You are being awfully forthright about things, Ms. Nyx. What’s the catch?”
Putting her hands on her hips while her tail lazily swayed around her, Nyx felt a delicious amusement. “Naturally, as you have clearly guessed, we succubi are very much like the Genies of old and will have our fun interpreting a request in ways potentially beneficial, certainly damning, or at least entertaining. Though, there is something about you that I like. I’ll even give you my word I won’t twist your wish this time. Won’t make promises for next time, nor will I speak for any other succubus you might get instead of me.”
Seeing another question already on Tanya's lips, Nyx cut the query off at its root. “We could talk all about the nature of demons and how the contracts work till dawn if you would like, but unless that is your desire, I think we should move on to actually granting your wish, don’t you think, Mistress?”
Tanya blushed again before nodding emphatically. “Y-yes. I… As I said, I just want to be beautiful.” Something about how she said that caused her to elaborate, “Not for any of those types of things you see in the old movies. I’m not looking to get more attention from just anyone or anything. I can admit to it being partly to do with my jealousy of my sisters and how good they look. Its more that I just want to look sexier for my girlfriend. She loves me dearly as is, and I love her back for that. But I don’t just want her love. I want her to lust after me.” As Tanya spoke, her words became bolder.
“Now that I can work with,” Nyx rolled her hand out palm up while pointing, the rest of her fingers lazily curled in punctuation to her statement. She grinned before switching to a firmer tone. “Mistress, your desire is to be sexually pleasing to your beloved. I will grant this for the offering of a month’s worth of your magical reserves, given your current strength and ability. Is this acceptable?”
Tanya nodded, “I accept.”
The circle surrounding Nyx burst into an array of runes that flowed and encircled her wrists, ankles, and neck, binding her to the contract they had made. While she was duty bound to perform at least the letter of the agreement, if not also the spirit, she could now move about freely.
She stepped forward, easily backing Tanya against the edge of the bed. “Now, I could just snap my fingers and make you a sexy slut of your lover’s dreams. But neither of us would be satisfied with that approach, now would we?”
Tanya shyly shook her head ‘no’.
“Alright, let's see what I have to work with. Strip,” Nyx commanded firmly.
Tanya’s lips quivered, two words almost on her lips, but a thought distracted her. “C-couldn’t you just make my clothes disappear?”
“I could. But then I might forget to return them. And those really are cute pajamas.” Nyx’s smile was soft for a moment before her dominance turned full force on the smaller woman. “Now, strip.”
“Yes Mistress.” The words just fell from Tanya's lips without a second thought. Both of them knew who the real submissive in the room was. Nyx could see the sexual nature within Tanya, that of a lustful little slut willing to bend over for her girlfriend any when and any where. But she felt so inadequate that it affected her confidence. And even a submissive slut needed enough confidence to project her willingness to be sexually available.
Honestly, give the girl a few years to put some more distance between her and her high school years, and she would find her confidence on her own. And Nyx got the distinct feeling that Tanya’s love would stick by her side all the way.
But she could also understand the desire to just be that person already. That and who didn’t love to have a bit more tit on their chest?
Without much fanfare, Tanya quickly shucked her clothes off, leaving her nude. Nyx’s gaze made her even more self conscious, but the demon was having none of that. “You know, you are rather beautiful in your own right. We are going to make you a lot hotter, but I just wanted you to know that I would happily bed you right here and now, contract or not. Succubus or not. And I imagine your girlfriend feels the same.”
Blushing and shyly turning her face away, Tanya slowly nodded. “I… I know. but I want this. I want to be my girlfriend’s fantasy. I want to be the whole package for her. She deserves so much for everything she has done for me.”
Cupping the smaller woman’s cheek, Nyx smiled warmly. “And that is why I’m not going to twist your desires this time. We are going to make you such a delicious treat for her. Aren’t we, my pet?” Something in being called ‘Mistress’ freed Nyx from her previous address. Rather than just pushing the woman onto the bed and going to town, Nyx felt it right to clarify things. “One last thing before we begin: you are aware of how I desire to both transform you and take my payment, right?”
Tanya nodded, still blushing all the while. “You are going to fuck me. Amy knows. We discussed it and she actually loved the idea. She wished she could be here to join in, but her part-time job called her in. Since it felt like a full moon night would be the best time to cast the summoning, she told me to just go ahead rather than wait another month.”
Nyx caressed the smaller woman’s cheek. “See, if more humans were like you two, this world would be so much a better place. So kind, so honest and genuinely loving. Humans care for each other more than they are told. I will admit to a mild disappointment because twisting the wishes of more deprived fools is an absolute turn on for me.” She bent down close. As their lips brushed against each other, Tanya’s were already beginning to warm and swell. “But I absolutely love little precious darlings like you.”
Their lips pressed together and the heat that started on Tanya’s lips spread out through her body. Down her spine, over her nipples, tingling at her finger and toe tips before it all rushed right between her legs. The arousal already building blossomed into a full orgasm. The small woman found Nyx’s other hand bracing at the small of her back, holding her up while her body quaked with the pleasurable release. With a graceful move, Nyx lifted her new toy and laid her on the bed, kneeling down between Tanya’s twitching thighs.
The succubus broke the kiss, leaving her pet gasping and moaning as the orgasm continued longer than it should have. “M-mah… MIS… Mistresssss… so … so horny… won’t stop… I… mmmah…oooh”
“It started, my pet, my project. You are now like clay to me. An idea I can tell you are well acquainted with.” Nyx glanced at the shelving around the room and all the clearly custom pottery on display. The idea of her lover performing that famous scene from ‘Ghost’ drew a teasing twist to Nyx’s lips. She was more than positive they had to have already done it at least once before.
Nyx sat up on her knees, looking at what she had to work with. The poor dear was barely more than skin and bones really. She gripped Tanya’s right ankle, lifting up her leg. Her other hand caressed the sorry excuse for a calf she found. Okay, it wasn’t a lost cause, there was muscle there. Likely from running to class a lot. But it was still too lean and wiry for her or Amy’s tastes.
She knew little else about this ‘Amy’ woman at the moment, but the request told her exactly the sort of sexual partner she lusted for through both Tanya’s own memories, as well as the threads of lust throughout the room. Nyx became aware now that she was in the bed the lover’s shared, that she could see and know the sort of sex life that Tanya and Amy had. And yes, Amy loved Tanya dearly, completely, in a healthy and powerful way that would last years. But the poor dear did want a bit more girl to fuck.
“Let's make you sexy for Amy, shall we?” She teased as she kissed the bottom of Tanya’s foot, drawing the orgasmic energies from Tanya’s pussy down her leg to meet Nyx’s lips. As she rubbed her hands over the tiny foot, it grew a few sizes. All the better to give support to the new shape her pet was going to take as she massaged Tanya’s foot and then down her leg. As she pushed her fingers into the muscles, she felt more and more resistance as the fibers strengthened, gained definition and grew. After a minute of feeling the right leg all the way up to Tanya’s now larger glutes, she repeated the process for the left.
Once both legs were buff and well worked, Nyx let them lay over her thighs while she rubbed down from Tanya’s hips, over her knees, and to her ankles. Each time, the human’s legs stretched longer. The effect pulled the bulging thigh and calf muscles inch by inch until Nyx was happy with her work. Now, instead of bulging like a bodybuilder, Tanya’s legs looked toned and graceful like a supermodel’s.
Moving up past Tanya’s tiny titties, instead, Nyx focused on her pet’s arms. Repeating a similar process of kissing, this time on Tanya’s palms, before massaging her muscles into bulky bulges before stretching out those arms to make the muscles fit the new frame.
Her pet bucked and moaned while she slid her hands down and pulled at Tanya’s hips, stretching them to a baby bearing width before rubbing over her waist, pushing and forcing her abs to flex and gain a bit of form. Her hands returned to Tanya’s abs, this time pushing upwards, forcing her whole torso to extend. Gasping her breaths, Tanya found her lung capacity grew as her ribs expanded to fit her growing body.
Leaning back again, Nyx grinned at the work so far. The frame was complete and once the poor dear was able to stand again, she would find that she had graduated to the tall girl’s club. She would easily hit 5’9” without heels, and most of that was her new sexy legs.
But this body needed to be more than just a frame.
An idea occurred to her and she bent down, brushing her lips against Tanya’s as she spoke. “I got a neat trick to show you. I would warn you to brace yourself, but I don’t think you can really hear me at the moment, can you?”
The woman whimpered as the climax had yet to ebb away.
Nyx kissed her pet’s lips. Then her throat. Sternum, abs, and finally the top of her mound. She had moved her body back to allow her to get her head down between Tanya’s quivering thighs. She pressed her mouth against Tanya’s dripping folds, enjoying the flavor for a moment before she took action.
Rather than licking those pussy lips, Nyx blew into Tanya like forcing air into a balloon. Tanya’s body expanded, primarily in her thighs, ass, especially her tits. The bug bites bulged out rapidly, a pressure building behind each nipple as they stuck out and throbbed with her heart beat. The clay woman arched her spine while her eyes rolled back in her head. Her voice was stuck mid-gasp while her mind went completely white.
Was a human capable of having two overlapping orgasms at the same time? Never say never. But even if it was impossible, it was happening to Tanya right now. As her pussy gushed into Nyx’s mouth, the demon drank in the nectar, and all the magical energies the fluids contained. She suckled and licked her pet to a chain of several more climaxes until she was satisfied.
Nyx sat up, looking at the still quivering woman, fully transformed into a living wet dream. Not quite a full bimbo look, and not merely a supermodel. Tanya would wake up tomorrow morning refreshed, renewed, and if Nyx had anything to say about it, inspired.
She crawled up over Tanya, their tits pressing against each other pleasingly, “Pet, when you awaken, you will find yourself every bit the sexually liberated slut you and Amy dream yourself to be. But I know the artist’s heart. You will lose none of that passion to your new lusts. In fact, you will continue with your pots and vases. But I would encourage you to pursue fertility idols as well. With your potent lusts, they just might even work.”
Nyx giggled at her own suggestion before her body floated away from the room in a gentle flow of twinkling lights, like fireflies scattering to the winds.
Those fireflies gathered back together in what was a guys room. She was still kneeling, totally naked and happily licking the pussy juices away from her lips when the energy did not stop glowing.
Her body shrunk in on itself. Muscle mass, breast size, even her height was melting away rapidly. The change forced all her arousal to focus between her legs with a sudden orgasmic bliss bursting from her clit as it swelled out. Balls dropped down between her legs as her pussy lips pressed closed. Her horns and tail shriveled to nothing while her skin took on a more human hue.
In seconds, what had been a muscle mommy of a succubus had become a pretty average guy. He just stayed there, on his hands and knees, panting from the womanly orgasm that had tore through his body.
Danny wanted to deny what happened. He desperately needed to deny it. The whole episode scared him.
It had never happened before. Suddenly tonight, under the light of the full moon, he had startled awake and found himself being pulled through a portal. At the same time, his male form had been turned into a very feminine succubus.
*She* knew everything to do and say as if she had been doing it for years. How the summoning worked. The rules for the contract. Even how to transform that woman into a full on wet dream.
And yet, Danny knew nothing of how it all came to be. Why him? Why tonight? Was it going to happen again? It was going to happen again, wasn’t it?
He was scared and he needed it to be a dream. But he could still taste Tanya’s pussy on his lips. His cock was still erect from his demonic orgasm.
He could feel the magic he took from Tanya sitting warmly somewhere in whatever one could call a ‘soul’. He could feel it. But if that was the case, could he use it? Did it require him becoming a woman again? Could he become a woman? Or did he have to go all the way to being a demon? Far too many questions and he wasn’t even sure if he wanted the answer to half of them.
He was scared because what if this kept happening? What if it was a man that summoned her next time?
What if he liked it?
