“Tea, Tracy?” Tracy looked up from where she was awkwardly playing with her hands. “Ah, no, thanks. I’m not a fan.” The other girl, “Lilith”, nodded, pouring out a cup for herself and for her partner, “Damien” - real names not forthcoming. Tracy had met them online, part of a group for people who happened to like a particular thing, and then on top of that they had turned out to live startlingly nearby. They got on well, shared many of the same interests, and now after a series of rash decisions here she was, sitting self-consciously in their living room and trying not to think about all that too much. They looked normal enough - her tall, pale and graceful, with long black hair completing the impression that she could pull off a Morticia Addams look if she’d particularly tried (she hadn’t, thankfully, keeping things a bit less intense for the first meeting), while he was a little shorter, a little scrawnier, with fiercely bright eyes hidden behind thick round glasses. They seemed nice enough, they both very much liked pet play, and online they’d offered to give Tracy some tips and show her a few things. For her part, Tracy just felt really… normal. Average build, average height, average brown hair of about average length. But she’d decided that for once in her life she was going to go out and experience something a little bit un-average. And so, here she was. “So...”, Lilith said, draping herself back into an armchair, “shall we get started then?” Without waiting for a response she turned to Damien next to her, adding, “be a dear and fetch it for me, will you?” He nodded happily, slapping his hands on his knees as he stood and marched off deliberately. Tracy’s eyes widened a little in trepidation. ““Uh, get… what?” “Oh, don’t worry”, Lilith responded with a wave of her hand. “Just his collar. I suppose that’s tip number one - always make him get it for you.” Tracy nodded. Should she be like, taking notes? While she was still casting about for anything to write with, Damien returned. In his hand he held a simple black leather strap, from which dangled a small silver tag. If it said anything Tracy couldn’t read it - on the whole it seemed more symbolic than ornate. Without pausing he kneeled down in front of her, looking forwards as he raised the back of his scraggly black hair. It wasn’t necessary - his hair wasn’t long enough to get more than a few scraps in the way of his bare neck - but it felt like a ritual that had developed back when it had been necessary, and now there was weight enough to the tradition that it was part of the process of willing submission. Tip number two, a small part of Tracy noted. Lilith took the collar as it was offered in Damien’s other hand, reaching down to clasp it firmly around his throat. He smiled in response; a warm, blissful, drifting smile as a slight but visible shudder ran through his body. Then it he suddenly tensed, a slight groan escaping him seemingly involuntarily. “Ssh”, Lilith whispered soothingly, moving her arm to pet him gently on the head, fingers digging lightly into the curls of his hair. “Just relax and let it go.” Tracy watched enthralled as he drifted back into her again, head tilting backwards as his eyes fell closed. Parts of his body were still tensing even despite the look of serene relaxation that swept over his face, looking down Tracy could see his hands flexing against the carpet, his fingernails pulling grooves deep enough that some homemaker part of her worried they might damage it. Her attention however was soon snapped back upwards as he started making another noise. This time it was urgent; a fierce, powerful growl emanating from deep within his throat, spilling past his teeth despite his best efforts to hold it in. “There we go”, Lilith continued, her voice that same soft, comforting note, “go ahead and let it on out.” He juddered. It seemed like - somehow he was increasing in size, mass, more like - it was as though the muscles were straining beneath his skin and desperately pushing their way to the surface. He began panting, thick, rasping breaths to draw in more and more air as his frame bulged and expanded, his hands digging noticeably into the carpet as Tracy realised they were now tipped with sharp claws. He shook his head, and as he returned to sitting under Lilith’s calm attentions Tracy saw that fur had begun cascading down his shoulders, with every gentle pet she gave him more and more of it seeped downwards to envelop his body. He fell forward suddenly, panting heavily into the ground as he lay on his hands and knees, and from his new position Tracy could see a bulge pressing urgently at the rear of his shorts. His panting soon melted into a desperate, wordless whine, and with an exaggerated eye roll Lilith leaned down over him. “Silly thing, you’ve gotten yourself caught up again, haven’t you?” She hooked one hand into the waist of his shorts, pulling them all aside in one practiced movement, leaving Damien to gasp in relief as his long shaggy tail finally slipped free. But, more than that, Tracy immediately realised that wasn’t the only thing that had come loose. His cock was now also urgently free, straining out in front of him as he resumed panting heavily. One of his hands - now little more than a thick paw with a vestigial thumb - made its way inexorably towards it, wrapping around his shaft to the best of his clumsy ability. Immediately he began working himself over, his face pushing outwards as he did so, almost as though the fiercer he pumped his cock the more eagerly his face slid into its new muzzle. Soon his tongue fell out of his mouth, dangling freely as it too slowly became longer and more animalistic. There was barely a moment’s pause as his shirt gave way, ripping in an uneven line along the centre against his heaving, bestial body. Lilith moved to stand directly above him, drawing one hand firmly along his back, petting and freeing him from the remains of his clothes at the same time. “Good boy”, she said lovingly, causing him to whine happily and drive himself forward into the carpet in response. “Who’s a good boy?” She was speaking to him like a dog, Tracy thought as she stared with wide eyes, but he didn’t actually look much like a dog. He was covered with shaggy black fur, and the tail that stood out proudly behind him looked like it could belong on some breed or other, but overall he simply looked far too hulking, too large and powerful to resemble something as benign as a dog. And yet the way he pawed at the ground and melted back into the strokes of her hand affectionately, even as he worked urgently at his startlingly large cock - if nothing else, he was certainly as obedient to her as a dog. “Et, voila!” Lilith turned, acknowledging Tracy directly for the first time since all this had started. “Here we have a perfect pet. Although...”, she made an exaggerated pout, as though considering it for the first time, “that is rather an advanced technique.” Lilith may have been finished with him, but Damien clearly was not yet finished with himself. He seemed to have settled into his newly-bestial form, but he was still urgently working over his straining cock, paws clenching against the carpet as he desperately chased his release. When Lilith spoke to Tracy he also seemed to register her presence again, looking up and regarding her with his startlingly intense eyes, still slightly hidden behind his now wildly incongruous glasses, their frames flexing awkwardly around his reshaped face. His eyes narrowed for a second, and then in an instant he was on the move, leaping up in one powerful motion and knocking her bodily back against the couch. Tracy found herself pinned helplessly, the sheer weight of him was more than enough to keep her down, and that was without his startling strength actively holding her still. “Aww, he likes you!”, Lilith said from behind him. “-!”, Tracy answered, any further response prevented by his pressure on her chest. Thankfully that was alleviated somewhat as Damien shifted, moving to hold her down with only one arm. While that did afford her a little more room to breathe, Tracy soon realised the purpose behind the change as his remaining paw fell back down to his cock, bringing himself back up to full stiffness in moments. Before she could react any further he bent his head downwards, his long tongue sliding out to lick wetly across her face. Despite the initial shock, the sensation was somehow perversely comforting - with her eyes reflexively closed she found herself sinking into it, almost enjoyed the situation despite the absolute absurdity of it all. From somewhere in the distance she heard Lilith speak again, this time with a little stronger edge to her tone. “Alright, that’s enough boy. Can’t go scaring the new girl too much, can we? Finish up and get off.” Immediately, Tracy felt Damien tense. Lilith had just enough time to add quietly “oh, that was a poor choice of words, wasn’t it?” Damien threw his head back, and then he came, clutching at his dick urgently as his hips thrust forwards again and again, his cum shooting forth, spraying wildly over Tracy. He felt his heavy paw curling against her body as he jerked and spasmed, each twitch sending another spurt of cum out against her skin. In seconds her face was coated, with a large amount spilling downwards to flow down over her chin, pooling inside her ample cleavage. Her eyes were long since closed, thankfully, but her mouth had opened when his claws dug against her flesh, and more than a small amount slipped between her lips before she could think to close them. The taste was… intense. It wasn’t bad, it wasn’t good, it simply was; distinctive and overpowering, filling up her mouth with the flavour despite the small amount she actually tasted. She genuinely couldn’t tell if she needed to spit it out or hungrily swallow it, but that decision wound up being made for her as Damien climbed off, the sudden release of his weight making her swallow as she inhaled reflexively. By the time she stopped gasping and had opened her eyes again, Damien had padded back over to be sitting obediently at Lilith’s feet. Before she could do anything else she felt something above her eyes, and instinctively wiped her hand across her brow to clear it away. She drew it back slowly as she realised what exactly it was she was wiping - somehow in that half-second moment she hadn’t quite realised - looking down to stare at the back of her hand. It was green. The thick, sticky mess that coated her skin, and, by extension, her face and a good portion of her chest, was a bright, contamination-hazard-looking green. Her eyes widened. “Oh, don’t worry”, Lilith said, from somewhere a million miles away. “It’s perfectly safe. Here, if you want I can get Damien to clean it off of you.” Out of the corner of her eyes, she saw Damien look up, licking his lips in anticipation. Tracy declined. She left in short order, unsurprisingly, barely pausing to accept the towel Lilith offered as an alternative cleaning method and wiping herself off hastily before she got the hell out of there. She wasn’t sure exactly what had gone down in there, but whatever it was wasn’t something she felt particularly comfortable sharing with virtual strangers. She was again thankful that she lived nearby - that being one of the reasons she felt comfortable enough to agree to the meeting in the first place - so it was only a few minutes before she was safely back at her place. She closed the door behind herself with a sigh of relief, leaning up against it for a moment in order to catch her breath. She had to go have a shower, she’d been promising herself one the whole ride home - she was sure she could still clearly smell the… whatever on earth that actually was on her - but it took her some time to manage to finally lever herself away from the door. It wasn’t that she didn’t want to have a shower, she really, really did, but just that… she somehow couldn’t make herself want it enough right now to actually get up and do it. It was like being really tired but unable to make herself go through the process of getting ready for bed. Thinking about that made Tracy realise - she was suddenly really tired. She wasn’t sure if it was a result of the nervousness of the upcoming meeting coupled with the bizarre, dreamlike result (it had been some sort of theatrical effect, surely. It couldn’t have been anything else, and already Tracy’s mind was working at softening the edges so it could fit more easily into her head), but suddenly all she wanted to do was lie down on the couch and rest. She’d started drifting over towards it without thinking, the idea of just taking a break abruptly overpowering. She flopped heavily onto her back, her knees arched over one armrest as her feet dangled freely, asleep almost before she hit the couch. Tracy dreamed. She was sure she had a dream, but she couldn’t place what exactly it was, almost even while she was in it. All she knew was that she was hot, unbearably hot, and it left her biting her lip while one hand snaked its way beneath the waist of her pants. There was a need so burning and fierce it was almost a physical pressure, driving her fingers irresistibly down against her bare skin. It wasn’t something she registered consciously - the urge was absolute, and she reacted to it without thinking, before she could think. By the time she woke up her fingers were already inside herself, massaging at her folds slowly but urgently. She woke up only reluctantly, her head lolling from side to side in absent bliss. But eventually she passed some internal tipping point, and enough of her thoughts had gathered to begin to register the situation. She was masturbating - frenziedly, even - which was not a normal way for her to wake up. Even that might have been within the bounds of acceptability except for the fact that she realised she still had some of the… results… of the meet-up clinging to her face., he cloying scent of it was absolutely filling up her nostrils, and yet- She didn’t stop. There was a recognition that she should, some sensible part of her mind informed the rest that the situation was thoroughly wack and needed to be stopped immediately, but still, she didn’t. She slid off the couch, falling to her knees on the floor. She was trying to get up, trying to go… somewhere, as though she could just walk away from the problem, but even despite that she still could not stop pressing her hand urgently inside herself. She put out her other hand to try to push herself off the ground, but the change in position just led to her getting a better angle, and then it only felt even more overpoweringly wonderful. It was- she didn’t want to admit that she couldn’t stop, so she let herself pretend that she just didn’t want to, that this was perfectly normal and it was a completely rational choice she was making to raise her ass into the air as she worked herself over, abandoning all pretense of stopping as she gave in to the unyielding goal of getting off. Without thinking, Tracy’s tongue slipped out and licked across her face. She only realised it was happening after the fact, and she knew she should be horrified, but somehow she felt only a massive increase of lust. The taste of what was left of the cum on her skin - of course it was cum, it had to be cum - made her shudder with pleasure. She- she needed more, needed more cum on her, but more importantly inside her, needed more to taste and to swallow and to fill her up. With a start she remembered that some of it had slid down between her breasts, pooling in her cleavage in a way that meant she hadn’t been able to get to it with the towel earlier, and was one of the main reasons she’d been so looking forward to a shower while she was driving home a million years ago. Rearing up onto her knees to free up the hand she was supporting herself with, she tore at her top in a series of rapid, awkward jerks, eventually pulling it aside enough to expose her breasts. Then she loving slid her hand inside her cleavage, withdrawing it to find with great satisfaction that it was amply coated in thick green goo, still wet enough to drip slowly down her wrist. Wasting no time she pressed her hand between her lips, licking hungrily at its delicious slickness. She came. Whether it was at the taste, the sheer debauchery of it, or as a reward for the treat she had been craving Tracy couldn’t tell, but the effect was the same regardless - her body locked up as she shuddered powerfully, her other hand quickly becoming equally wet as she orgasmed emphatically. After several long, blissful moments, she was for some reason compelled to withdraw that hand from her crotch and bring it up to her face, inspecting the results of her efforts. It was covered with a thick layer of dripping green, more than her other hand had ever been, despite never having been anywhere near where the Damien creature had coated her. This was from her. This was something her own body was producing now, and she could feel it sliding unstoppably down the inside of her thighs even as she realised that. She crammed that hand in her mouth instantly, desperate to taste more of the wonderful slickness, while her other hand shot down below her waist to guide her through another series of powerful orgasms. She couldn’t stop orgasming, now it wasn’t about masturbation, she didn’t have to do much more than clutch desperately at herself as her body came again and again automatically. She couldn’t stop, she could feel the slickness of it sliding all the way down her legs, pooling onto the floor beneath her, covering her hand absolutely on the way. She came, her feet skated out beneath her and she came, her toes curled and her hands twitched and she howled in frantic ecstasy as she came over and over again, and it all felt so powerfully, unstoppably good. At some point she fell backwards. She didn’t even register when exactly, all Tracy knew was that at one point she was kneeling and then she was flat on her back, writhing against the increasingly wet floor with both hands back to massaging her needy sex. Somewhere in the absolute cacophony of sensations she was going through she felt an array of extra pressures, pulling and pushing at her somehow from inside. She curled up slightly as her body tensed, even as her hips still thrust forward absently to the rhythm of the constant stream pouring out of her. Suddenly she felt something else give inside herself, some extra piece of release that she had somehow not yet attained, and with a visible jolt her body swelled, bestial muscles of her own growing into place. She was becoming like Damien, she managed to realise, even as her mouth filled up with sharp, pointed teeth. Her hand flexed as her new claws grew in, managing not to hurt herself as she still grasped urgently at her body only as a thick layer of protective fur swept over her flesh. She grunted, then a low moan spilled out of her involuntarily, finally giving voice to the rampant needs and desires that were engulfing her. “Ffffuuuuu...”, she started, eyes screwed shut against the absolute sensation of it all. “...uhhhhhhh…” The tone of her voice had begun to change. She could hear it herself, but she couldn’t stop it, couldn’t make herself want it to stop. “Uuhrrrr…” There was a sudden change at her crotch. She felt her folds suddenly slide smoothly closed, while at the same time her clit surged dramatically, becoming long and large as her paws transferred their attention automatically. She grasped around the steadily growing shaft of it, and then with a dramatic shudder she felt something else slip free from within her, and in moments her other paw was cradling her new balls as they surged with thick, urgent cum. “Rrrrrrrrr!” she roared triumphantly, her tail sliding out behind her as she came emphatically through her new cock, arching the resulting stream of bright green cum backwards to fall against her heaving chest. For some time her hips twitched energetically, sending spurt after spurt of cum back against herself, until finally, after what felt like hours, she was still. It was some time before she got back up. For a long while was content to simply lie there, licking contently at the puddle she’d surrounded herself with, enjoying the roughness to her tongue and the long rumbling purr that echoed in her throat. But eventually she found herself being driven back to her feet, standing unsteadily at first on her new paws. It was becoming increasingly clear that even such an emphatic series of orgasms were only a temporary respite - she needed more, urgently, and a bestial lust was rising up in her again unstoppably. Her hand dipped down to her cock, already straining upwards again as she ran one clawed digit along it teasingly. She looked up, seeing her reflection in a nearby mirror for the first time since everything had happened. She looked like a big wolf, some sort of human-wolf-girl with the notable addition of her dick. It was green. She was green - she hadn’t really been looking before, or hadn’t noticed given the intensity of everything that had been going on, but her dick was bright green, with the rest of her fur a slightly darker shade. Her coloration was enough to hold her attention for a little over five seconds, until she instinctively licked her lips and felt how her tongue left them stained with dripping green ooze, and the sight of it sliding down her face was enough to make a corresponding bead form on the tip of her cock. And with that the distraction was finished, what she looked like was irrelevant, what she was was the only important thing, and she was an animal that needed to fuck and to take and to spread, to take the powerful green fluid she was brimming with and infect others with it. She needed to- she needed - she hadn’t realised her thick paw had closed around her cock and was sliding up and down against it urgently until she trembled slightly under her attentions, but she knew that wasn’t going to be enough. She needed someone. WIth considerable effort she managed to open the door to get back outside, loping off in a four-legged run out into the fading light and towards the park. Penny jogged later than most people. She worked late, and so exercising earlier wasn’t normally a possibility, and the dangers of a small town park in twilight held little terror for her. So like most nights she seemingly had the park to herself, listening to music pumping in her ears as she rounded yet another bend. There was movement. Penny’s body reacted by itself as something sprang out from the bushes, dropping her automatically into a self-defense stance. She dropped as it jumped at her, one leg sliding backwards to prop her up while her hands pushed upwards, flicking her assailant up and over her with its own momentum. Something hit her in the face as it went past; something hard but also slickly wet, and Penny definitely felt the impact of it as she spun around to face her attacker. Her assailant, whoever they were, landed somewhat awkwardly on the gravel path behind her, winding up on all fours as their feet skated for purchase and their tail- what. Penny blinked. The creature rounded on her, flowing gracefully from its four-legged stance to be standing on two, seemingly enjoying revealing itself to her in full. It was a she, if her sizeable breasts and curvy body was anything to go by, although as Penny’s wide eyes looked it up and down she soon noticed that it was also sporting an unmistakably masculine erection. The creature’s cock was bright green and dripping with a thick, equally green fluid, drops of which were smeared across the rest of the creature’s crotch. Drops of… Penny quickly touched a hand to her face, finding it sticking to her skin slightly as she wiped downwards. Pulling away, her eyes flicked off her opponent for a second to look, seeing long green strands connecting her hand to her face. Oh, she thought. Somehow, nothing more than that seemed to be immediately forthcoming. It was further movement from the creature that snapped her back into the moment. She dropped back into her fighting stance reflexively, but the creature seemed content to stay where it was rather than move in towards her again. Instead it simply moved one of its paw-like hands down to its crotch, wrapped it around its shaft, and began quietly masturbating. Within a few moments, its other hand reached down too, lazily cupping its balls while the stroking motions slowly began to increase. Then the creature looked at her, the almost-human face looking her directly in the eyes. And it grinned. Penny considered her exits. The path continued behind her and reached the edge of the park in short order, it wouldn’t be too hard for her to outrun the creature long enough to get back to the road where other people would see them. But making a break for it would mean turning her back on the creature, and that didn’t feel like a good idea. She tried taking a step backwards, her guard still raised and her eyes still fixed firmly on her opponent. It responded by taking a step forward too, but only one - keeping the distance between the two of them constant, and all the while continuing its dedicated masturbation. Penny’s lip curled. This wasn’t going to be as easy as she’d hoped. She had to either get away or go through it, but it looked like it had vicious claws and she couldn’t just turn away and where was that smell coming from that was filling up her nostrils and she had to get away but she couldn’t look away and she had to go but she couldn’t and she had to... Behind her, her foot slid out slightly against the gravel, causing her to drop a few inches in her stance. She felt… tired, all of a sudden? Or was it- there was something, she couldn’t place what it was, but it felt like her head was spinning and full all at the same time and that creature was still grinning and still masturbating and she couldn’t look away and suddenly she realised that it wasn’t just the slickness it had left on her face but she was drooling, she was drooling somehow because she wanted it so badly and her foot slipped again and this time she lost her balance entirely, falling down to her knees with a jolt. The creature approached her slowly, a sway in their hips carrying all the way down to her tail. Penny couldn’t bring herself to even try to back away, she needed the nearness, needed them - her - to be closer. There was no foreplay, no delicate initiation. As soon as the creature reached Penny she simply pressed herself forward, sliding her cock inside Penny’s mouth without a word. For her part Penny accepted it hungrily - already it was perfectly slick with more of that wonderful green goo, and the feeling of that thoroughly coating her lips was enough to make Penny tremble with bliss. She felt the creature’s heavy paws land against the back of her head, claws flexing out just a little as she pulled Penny forward, pressing her down until her cock was buried to the hilt. Penny didn’t struggle - she couldn’t struggle. She needed this, she’d always needed this, even if she hadn’t known it before, but now in this moment she knew absolutely that the only thing she ever wanted to do was be used and taken absolutely by this beautiful creature. It was like a switch had been flipped inside her and she had suddenly come to some great epiphany, and even though it sounded insane she knew that she would be happy so long as she was allowed to suck this wonderful cock, to present herself and be filled at every opportunity. The creature was pulling her slowly backwards and forwards, using her to masturbate with with no input from her, and that was perfect, utterly perfect. The thought of being a mere object for sex, a simple plaything designed solely to give pleasure to her mistress, was so wonderful that her body shuddered involuntarily, causing a blissful slickness of her own to slide slowly down the inside of her thighs. Above her, she began to hear a low growl; quiet at first, but quickly rising in intensity. Penny felt her heart beat faster in response, knowing what was happening and willing it on desperately, needing to be taken and filled utterly. Tracy’s eyes snapped open. She was riding her urges entirely now, lost to her bestial lust, but now some new need opened up within her. She withdrew abruptly from the girl beneath her, much to her seeming dismay, although she didn’t resist as Tracy followed up by pressing one of her hind paws firmly against her chest, tipping her over backwards onto the ground and ensuring she stayed there. By this point Tracy knew she was close, the desperate need for release boiling within her, but somehow more important than that was the need to… spread - she had to take this girl and convert her, change her, corrupt her, and she knew instinctively that this was the best way to do that. It felt so good to give in to that need, to know that she was going to take this random girl and make her utterly hers; Tracy only barely recognized that a steady stream of green drool was dripping over her chin and onto her chest in anticipation. “Rrrrr I’m gonna make you… mine”, Tracy rumbled, words tumbling awkwardly from her mouth as she masturbated furiously. The woman below her answered instantly. “Yes! Please, I need it I n-” Tracy came. She roared wildly as her body tensed and released, her balls surging as arc after arc of thick green cum launched out to land over the other girl’s body. Tracy panted openly as she aimed her still-ogasming cock lazily, ensuring she coated as much of the girl below her as possible. For her part, the recipient of Tracy’s attentions could only writhe and moan, seemingly caught up entirely in utterly rapturous release. Looking down with one eye open, Tracy was pleased to note that the girl seemed to be orgasming in sympathy; her own slick fluids mingling deliciously on the inside of her thighs with Tracy’s thick green coating. With one last shuddering spurt, Tracy finished. She paused briefly, looking down with a satisfied grin, before dropping quickly to the ground herself, placing one heavy paw firmly on the center of the other girl. She pressed her weight down on it steadily. The message was simple - stay. It was about control, about ownership, and the submissive look she received in response told Tracy that she had been understood. Then, achingly slowly, delaying long enough that the other girl could feel the huffs of hot breath from her muzzle against her skin, Tracy lowered herself down, and began licking the girl’s face. Penny felt her hands clench involuntarily against the gravel beneath her. This feeling, even just the weight of her mistress on top of her, the dedicated, intense focus of attention she was being given - all of that was already enough to leave her moaning insensibly, her eyes screwed desperately shut. But now, this added dimension of her tongue dragging across her flesh, lapping eagerly at the coating she had just been given, but - there was more to it than that. There was a response, a movement - she felt her skin pull against that rough tongue, and then somehow not snapping back into place once the it had moved on. She- she was being changed, reshaped; moulded into something new at the specific command of her mistress, and her body couldn’t help but respond. She came again, she couldn’t help it - it was a release just to realise what was happening, realise that she was being converted utterly into a toy for her new owner, a lustful beast that could only suit her desires. She felt her face push outwards into her new muzzle, and she was so happy that her body responded by itself, a tail sliding out to give her the only proper way to express her joy. Fur chased behind the tongue rasping across her flesh, slowly wrapping over her body as she writhed under the lavish attentions of her mistress. Her breasts swelled, bursting free of her top as she became the visibly slutty pet that she needed to be, her own tongue lolling from her mouth as she panted desperately in insatiable lust. She had no concept of time, and only the barest measure of how many orgasms had carried her along throughout the process. Finally she felt the pressure on her chest recede, and had a dim awareness that her owner had stood back up away from her. Penny opened her eyes again slowly looking up in an expression of absolute submissive happiness. She got to her knees, noticing on the way how her hands were now much closer to paws - her whole body had been thoroughly altered, leaving her some mix between dog and human, although her owner’s firm grip on the top of her head assured her she was definitely something less than the latter. Her fur was green too, albeit a somewhat duller shade than that of her mistress. Aside from the color, she looked like some sort of humanoid border collie, her shaggy tail wagging even faster behind her as she looked herself over in awe. She was interrupted as the pressure on her head shifted, sliding into a powerful grip that pulled her upwards. She responded automatically, drifting obediently to her feet to leave her standing face to face with her mistress. She looked away instinctively, not wanting to appear to challenge her dominance for a moment, but then she was swept forwards, locked into a passionate and all-consuming kiss. She felt that same rough tongue press its way between her lips, circling hungrily inside her mouth to seek out any remnants of the cum that had been missed. Once her mistress was satisfied she pushed herself away, leaving for a few seconds a thin strand of green delicately connecting the two of them. Finally, for the first time, she spoke. “You can call me… Mistress”, she said, her voice so rich and commanding that Penny felt her knees instinctively go weak. “And you”, she continued, fixing her utterly with her mesmerizingly green eyes, “are Pet.” Blushing enough to show through her fur, Pet nodded. The next day Tracy arranged to meet up at Lilith and Damien’s house again. She brought her Pet with her, indeed, she found it difficult to go anywhere without her; without the constant, eager source of relief she found it difficult to keep her head together, and ran the risk of sinking once again into wild, animal lust. She had managed to find a leash for her though, walking her on all fours up to the front door of the house. Pet tried to open it herself, trying desperately to be a good girl and clear this obstacle from her owner’s path, but in practice all she could do was scramble with her awkward paws against the wood in a vain attempt to manipulate the handle. Laughing, Tracy leaned over her, rapping sharply against the door. It was opened after a few moments by Lilith, looking almost exactly as she had the night before. She raised a single eyebrow at the scene before her; taking in the two of them with apparently little more than mild curiosity. “Well well well”, she said softly, “you have come a long way, haven’t you?” Soon they were all in the living room, Lilith and Damien back in the same position as they had been before - Lilith on an armchair across from Tracy on a couch, while Damien stood behind his mistress and Pet sat obediently at the feet of hers. Sitting there, in the same place as it all had started, with the rich smell of decadent sex filling her muzzle, Tracy felt her unstoppable lust rising, threatening to overwhelm her ability to keep her composure. With a quick, rumbled growl of command she attracted her Pet’s attention, pointing with one lazy claw down towards her cock. She needed no further encouragement, leaping up happily and setting her mouth to work eagerly servicing her owner.Tracy finished quickly - some small logical part of her mind suspected that this setting was responsible, getting her far more worked up already than normal, but for the most part she was far too absorbed in grasping the back of her Pet’s head against herself and cumming repeatedly. Lilith and Damien looked on quietly, some mixture of pride and approval on their faces, as though they were watching a friend enjoy a fine meal they’d prepared. Eventually Tracy pulled Pet back lightly, giving her the signal to slide herself free and moving her body upwards, giggling as her breasts brushed against her mistresses but keeping going until the she was level with her Mistress. She then fell forwards; kissing Tracy passionately but, more importantly, allowing her to transfer back the delicious cum she had saved, thrilling as her owner purred happily at the wonderful taste. “Ah, I remember that stage”, Lilith said from across the room. “Don’t worry, the unstoppable addiction to cum will fade before too long.” Tracy pushed Pet away for a moment, licking her lips lightly before responding. “Is there a way that it could not?” She laughed, and Lilith laughed, and Damien and Pet laughed (even if she wasn’t sure she got the joke), happily and together for some time. “No but seriously, this is rad as heck”, Tracy added.
