#2 of Smut

It's been a long time since I wrote anything transformation related and I've never written anything futa related, so this story might be a bit rough (even after proof-reading and editing).

FYI: Luna's one of Shadow's daughters (the other being Saleen). Shadow is a weredragon, and both Luna and Saleen inherited that particular trait, whilst their demonic heritage comes from their dad, who is JD.

Luna looked out of her office window, watching the hustle of the streets below. It had been five years since she had opened her captured asteroid to the public, and since then it had gone from strength to strength. It had gained in popularity so much, so fast, that she had had to once again hire another mining ship with the capabilities of capturing and towing such massive objects. So far, that second asteroid, whilst smaller than the first, was lashed securely to its new sister and was currently undergoing some serious internal terraforming. Rockscaper units, produced by the Synthenoid Empire, were busily chewing away the rock and ore, reforming the detritus and slag into a mush that would be laid down as roads and applied as strengthening layers for the multitude of tunnels and chambers they were boring into it. They were much like insects, using what they could to build hives. Except this hive was to Luna's exacting standards and made of far different materials. Once that asteroid was complete and ready for inhabitation, she would open the main transport tube that was just one of several flexible tunnels linking the two asteroids. Right now, though, said tunnels were still bundled up in their component parts down in storage. They would only be installed once Asteroid-2's hydroponics and environmental systems were in full swing and the barren lump of rock and ice was as colourful as the one she was standing in.

The crimson and black demoness rolled her shoulders and rubbed at her temples. She ached all over and she grumbled. Whilst she loved her mother very much, she just wish she hadn't inherited certain aspects of the dragon's genetics. A pair of strong hands landed on her shoulders and Luna sighed as the tension oozed from her muscles under powerful fingers and thumbs.

'Morthran's House has been shut down indefinately and your Enforcers have hauled him to the nearest airlock.' Kirsi said as she massaged Luna's shoulders.

'Mmmhm. Good riddance to bad company. I will tolerate most things except for people trafficking.' Luna murmered. She leaned back against the ice demon, and Kirsi gently slid her arms around Luna. She kissed the top of her head, between her spiraling ram's horns and sparks fluttered into the air from the smattering of runes carved into them. 'Was his death slow?'

'It was miserable, too. Captain Dushan let his subordinates have some fun before Morthran went for a space walk without the correct equipment. One of my orbital patrols is tracking his body and will collect him before he crosses into the main traffic lane. Y'know, so that anyone who sees his worthless carcass gets an idea of what's in store for them if they fuck up bad enough.' She said, 'Damn, you're tense. What's the matter? Need to Change, again?'

'Mhm. But I also need sex, too, and I'm not sure which one should come first.' Luna replied.

Irritation clipped her words and Kirsi laughed lightly, stroking Luna's bare arms. Luna shuddered as Kirsi traced the tips of her fingers down her arms, leaving tickling pinpricks of ice in their wake. Luna brought her tail up between Kirsi's legs and wrapped it losely around her diamond-tipped tail, and started stroking. Kirsi's hands slipped across Luna's stomach and she felt her way up to her large breasts. Luna's plump lips parted slightly as Kirsi circled her nipples through the fabric of her thin shirt, squeezing gently as they became erect.

'Now do you know which you need more?' Kirsi purred into the back of Luna's neck.

'Oh yes...' Luna sighed as Kirsi traced light, frosty kisses around her neck. Luna turned around in the other demon's embrace and kissed her softly, her forked tongue probing at Kirsi's cool lips, slipping beyond to move slowly against her own, sharp tongue. Kirsi moaned deeply as fire trickled down her throat, into her belly and started a slow, inexorable spread through her body. 'I need you right now.'

Luna pulled away from Kirsi, turned to her desk and pressed a button on one of the many control interfaces there. The broad, wall-to-wall, floor-to-ceiling windows went from tinted to fully opaque, leaving Luna's lushly furnished office bathed in the warm glow of her antique reading lamp and the heatless flames that flickered in the iron sconces that lined the room. Kirsi cocked her head slightly as Luna moved across to the otherside of the room, shrugging her leather vest off and pulled her halter neck top off, discarding it on the floor with the vest. Kirsi licked her lips as she watched the fire demon move, biting her bottom lip as Luna rolled her hips and stretched with a pained groan, reaching both hands towards the rocky ceiling, the soft glow of the sconces highlighting her curves and hard muscles. Her heavy breasts swayed gently as she arched her back, tail curling up. There was a series of pops and cracks as she stretched, then she pulled her belt off, tossing it aside. He hands slid around her hips and she grabbed her backside, sinking her nails in and she looked coquettishly over her shoulder at Kirsi.

'Help me out of my jeans, sweetie?' She purred. She looked Kirsi up and down. The ice demon was stood rigidly, glued to the spot, staring hungrily. A cool mist rolled from her twisting horns and a few, small snow flakes gusted up into the air from the runes that coated her glimmering blue crystals. She reached back and pulled her silver hair from its tight braid and shook her thick locks out across her shoulders.

'It would be a pleasure.' She replied huskily and stepped forward.

She pulled Kirsi into another kiss before letting her undo her jeans. Kirsi slid her three middle fingers into Luna's jeans, hooking her pinkies and thumbs over the tops and slid them down, crouching as Luna sank back onto the plush sofa.

She lifted her feet up, 'You forgot my boots.' She grinned.

'Doesn't matter. They can stay on.' Kirsi said as she stood up again.

She undid the buckles and clips on her armoured vest and let it fall to the floor with a heavy thud. Luna looked on, her eyes ablaze as she watched Kirsi slowly slide down the invisible zipper on her smartweave shirt, watching with baited breath as the line became a slowly widening V that exposed Kirsi's considerable cleavage and revealing the beginning of abs that made Luna salivate. Kirsi was far older than Luna, verging on a thousand years and her figure showed it physically and her aura hinted at the power of the harshest ice storms imaginable. The ice demon looked as if she had been carved from an ancient glacier, with white skin that glistened the purest of blues when she moved. She was curvy, also, with breasts that overshadowed Luna's. She was a 6'11'' killing machine with a lifetime of hard combat in every environment imaginable. And she had the best cock Luna had ever had. Kirsi smiled slyly as if she knew what Luna was thinking. She peeled the smartweave shirt off, finally revealing those glorious, heavy breasts that glittered with frost, her blue nipples rigid.

Kirsi ran her hands up her abs and cupped her breasts, hefting them and pressing them together. 'These what you want to see?' She purred as she rolled them in her hands. 'Or is it this?' Her hands slid back down and she undid her belt, un-buckling the thigh holsters for her two heavy blasters and her array of combat and throwing knives. She lay them carefully on the low coffee table and undid her combats, reaching into the waistband and pulling out her semi-flaccid cock.

Luna stared at it, gnawing on her bottom lip, her left hand sliding down stroke at her pussy as her right toyed with her breasts. Kirsi' cock throbbed in her hand, growing in size as she became hard and her glacial eyes were aglow with lust as she watched Luna frantically bring herself to a loud, moaning orgasm. The haze cleared from Luna's mind and she licked her fingers clean, her gaze sliding back to Kirsi. Kirsi approached, tugged her pants down some more and turned Luna around on the sofa, so that her knees were on the cushions, thighs parted, her elbows resting on the back.

She wriggled her butt teasingly. 'Hurry up and put it in.' She said breathlessly.

'Or, how about I just stand here and jerk off all over your arse?'

Luna swore at her and wriggled some more, her barbed tail weaving a languorus pattern in the air. Kirsi gently pressed the tip of her index finger against Luna's clit. Luna cried out in surprise as ice tingled like cold lightning through her pussy, down her thighs and across her stomach. She twitched and writhed, gripping the back of the sofa as Kirsi continued tracing her swollen folds with her magic. A faint steam clouded between them as demonice and demonfire collided. Luna came, crying out, sagging onto the sofa. Kirsi grabbed her hips in a firm, commanding grip and pulled her back up. She pressed the tip of her ridged cock against Luna and slowly pressed into the convulsing heat, her girth spreading Luna wide. Luna groaned, gutteral and long as Kirsi pressed deeper into her with a foot of twitching ice.

A sigh escaped Kirsi's lips as her hips pressed against Luna's firm buttocks. Luna's heat was volcanic and addictive, and she started moving, pulling back several inches before slamming her length back inside the squirming fire demon. Kirsi wove strands of magic as she started an even pace, always pulling back several inches before slamming back into her lover. She wove tendrils of magic into existence and guided them around Luna's body, ethereal chains made of snow and ice wrapping firmly about her torso, curling around her pendulous breasts and tickling her nipples. Kirsi ordered the magical tendrils to keep it up until she was spent.

Luna moaned as the slivers of cold slowly seeped in through the heat flowing from her body and curled sensuously around her, one wrapping around her waist, two more curling around her shoulders and down her arms, one had draped itself around her neck and was stroking seductively at her lips whilst two more had wrapped themselves tightly around her breasts and were squeezing, massaging and tickling. She opened her mouth to let out a moan of approval, but it got caught in her throat as Kirsi slammed back into her harder than before. Luna thrust herself back to meet her as best she could with a grunt, but the ice demon had her held fast in her powerful grip. All Luna could do was enjoy the torment.

'All I need is a blindfold.' Luna gasped hoarsely. She could feel another orgasm racing up on her already, goaded on by the thick, cold, twitching cock that moved deep inside her and by the magic that had wrapped itself around her tightly.

'I'll tie you up properly next time.' Kirsi grunted. She groaned. Luna's heat, the tightness of her pussy, the twitching of her back muscles and swaying of her heavy breasts... It was all becoming too much for Kirsi to handle.

She twitched deep inside Luna. Gritting her teeth, feeling the fluttering spasms and tightening of muscles in her abs and thighs, she fought back an orgasm as Luna came, her body convulsing hard around her, squeezing and gripping at her cock. Kirsi was rigid, almost going crosseyed as she fought back the urge to let go. She let out a steadying breath and looked down at the black lips that twitched and glistened with liquid silver. Kirsi started thrusting again, slowly at first, then harder and faster as Luna begged her to fuck her. Kirsi reached forward, grabbing a fistful of Luna's jet mohawk. Her hair was soft, downy to the touch and it was perfect for pulling the fire demon's head back enough to cause just the right amount of pain. With her other hand still firmly gripping Luna's hip, she ordered her snowy tendrils to tighten their grip a fraction as she pounded hard into Luna. Kirsi started to moan, softly at first, then louder as her desperation climbed. Luna was calling her name in a strangled, lust-fueled voice with each thrust and it urged Kirsi onwards, and she pounded into her wildly.

Kirsi knew she could hold on a while longer, had the resolve to stave off her orgasm for another three minutes at the most. Until she felt something warm questing between her legs, tickling at her soaked labia. Kirsi's movements faltered fractionally as the heat parted her lips and slid inside her. She felt as if she had been spread wide. Luna chuckled. She was using her magic as Kirsi was using hers. Except Kirsi now had a deliciously warm cloud of embers prickling playfully deep inside her, whilst a smouldering ethereal finger circled her clit. She moaned and forced herself to keep moving. Luna was sent over the edge again as Kirsi redoubled her efforts, both physically and magically, her breath coming short, turning to lustful groans as Luna forced her to the very edge even as she herself came again. Kirsi relentlessly worked at Luna, letting out a short, joyful laugh as another orgasm shook her lover. Another was hot on its heels and soon Luna's orgasms all merged into one, long, writhing cacophony of ecstacy.

Between the rolling orgasms, Luna managed to utter a single word. She grinned, grinding her teeth together as another orgasm sleeted through her. Kirsi moaned, long and deep, her hips twitching, her cock pulsing hard, spurting her thick, cold silver cum that mader Luna's pussy overflow. Luna felt it spurt and ooze out of her, trickling down her thighs. The spell they had woven for each other broke and Kirsi pulled out, staggering back to admire her work, gasping for breath. Luna was shuddering and full, her face buried in her arms as she leaned against the back of the sofa. Thick silver strands slid tantalizingly from her twitching pussy, oozing gently over her clit to form glistening droplets of seed that pattered onto the leather cushion.

'How d'you feel now?' Kirsi gasped. She lowered herself into a chair, relaxing into the plush cushions.

Luna flopped down onto the sofa, laughing. She reached down, undid the buckles on her boots and kicked them off. 'I still feel like hell.'

She wriggled out of her jeans and panties, kicked them to the floor and stretched out with a grunt. Kirsi watched her, admiring her curves and the hard planes of her muscles, wanting to take her to bed so she could make love to her... Luna flashed a coy smile, her gaze lingering on Kirsi's exposed crotch.

'As much as I 'd love to go for a round two right now, I really must retire to my lair. My inner dragon will wait for no one, not even an ice cold goddess like yourself.' Luna said. She swung her legs over the edge of the sofa and pulled herself to her feet. She swayed on the spot a moment, spots dancing before her eyes for a few seconds before clearing. A lance of sharp pain ricocheted around her body and she almost doubled over with a series of short, sharp cramps. Kirsi bounced from her chair and steadied her.

'Come on. This is my fault you've delayed it so long-'

Luna waved her words away, 'No it's not. If I hadn't wanted you to fuck me, I would have said so. You know that.'

Kirsi planted a gentle kiss on Luna's head. She zipped herself back up and helped Luna towards a door that was hidden at the back of the room, behind one of many heavy drapes and tapestries. Luna pressed her hand, fingers splayed, against the digital reader that was hidden within the door frame and they stepped through into passage hewn from the rock and ore when it slid open. Kirsi helped her down the winding, stone passage that was softly lit by spidery veins of a pale blue crystal that had been discovered in this this particular section of the asteroid. It was also the main reason why Luna had chosen this section as her workplace and home. She deemed it far too beautiful for those that her enterprise attracted. Finally, after what felt like long, painful hours of scurrying down stone passages, twisting back on themselves and ocassionally walking in the opposite direction, the two demons pushed their way through a large oval blast door that had been camouflagued with a holographic image that made it blend seamlessly into the rock.

They had stepped into a giant cavern, almost big enough to be called a valley. The ceiling was swathed in a magical darkness that glittered and swirled with the glow of distance stars. A game trail led from the outcropping they were on, winding down the steep slope, through clinging vegetation and vanishing into the cloying, muggy darkness of the forest below. Somewhere in the distance, Kirsi could hear the waterfall that had been the first thing Luna had installed to get the hydroponics of the place underway. Birds sang to each other, fluttered through the air and the mournful bleats and honks of prey animals could be heard in the distance. Somewhere in here, in this massive, homemade forest, was a large meadow seeded with wild flowers that Luna regularly plucked for selling at the bazaar. The meadow itself was surrounded by meres that were fed by the winding river that snaked out of the depths of the forest.

Kirsi inhaled deeply, relishing the scent of the vegetation that surrounded her, clearing the scents of busy, enclosed streets from her nose.

Luna slid from Kirsi's side and sat down heavily beside a small pool of luminous blue water, the basin lined with crushed amethyst. She doubled over with a sharp gasp, looking at her pained reflection in the water, her fists ripping up clods of dirt and moss as painful spasms wracked her body. She gritted her teeth, feeling them slowly lengthen, sharpening as her body forced the issue of transformation.

'I'll wait for you in the cabin.' Kirsi said and turned to make her way up a wooden path to the stone cabin that was nestled within a stand of trees, thick emerald vines draping across its slate roof like a spider's web.

'You don't have to.' Luna uttered between pained groans. She turned her eyes from Kirsi, her face heating with embarrassment, 'You've always been curious... And I don't mind. We've done far worse things together.' She tried cracking a sheepish grin but instead cried out as her bones creaked and wings started pushing their way out of her back, stretching her flesh as new bones, muscles and tendons grew into being, the existing ones growing or shrinking, depending on how the shift in anatomy demanded.

Her tail started thickening, growing longer and her nails lengthened, swelling into black talons. Her spine stretched, head being pushed forward, away from her body as her skull shifted from humanoid from draconic. Scales grew from her skin, bright as polished ruby and obsidian. Muscles bulged, bones snapped and she pushed herself upright, onto her all-fours as the pain subdsided. She tested her broad wings, flexing each long finger, one after the other. Her sinuous, whip-like tail lashed down into the ground, sending up a gout of dirt, vegetation and shattered stone. Kirsi stood back, looking up at Luna, her eyes wide, mouth open. A deep, rumbling purr vibrated up from the weredragon's chest as she stretched and flexed the last of the kinks from her body, luxuriating in the fresh surge of energy and strength, basking in her draconic heritage.

'You're beautiful in this form, too...' Kirsi said softly as she took in Luna's appearance. She was 10'' at the shoulder, with an 8'' neck. Kirsi judged her to be almost 30'' from snout to tail-tip and her wings just as broad. Crimson scales coated her powerful body and larger, black scales lined her belly, wings, shoulders, snout and thighs. Rows of vicious looking black spines lined her back and the runes in her curling horns glowed fiercely. Luna turned her smouldering gaze upon Kirsi, head held high, wings spread. She blew a smoke ring at the ice demon, turned and kicked off of the ledge, beating her wings hard as she soared into the darkness above with a thundering roar.
