Seracen groaned softly, eyes closed. She felt a little odd, but nice. It was like she was floating on a cloud, mostly weightless with something soft and clingy wrapped around her body. The dragoness’s head was a little fuzzy but somehow that made it better, her slow thoughts comfortable and relaxing. It was so tempting to simply drift off back to sleep and Seracen did, falling unconscious again. She woke up once more an indeterminate amount of time later, feeling a little more clear-headed, but still didn’t open her eyes.

Where was I? Seracen thought hazily. I was…I was out hunting and then…here? The dragoness gave a low huff then froze. There was something in her maw. She hadn’t noticed it before, but she could feel it now, spreading her jaws. It was a long, thick tube, practically reaching her throat and there was a muzzle strap keeping it place. That she could clearly feel, tight against the soft scales of her snout. Breathing more quickly now, Seracen cracked open her eyes, wincing.

She was in a room, a human room, and there were bright white lights above her, throwing everything into stark relief. The luminance stabbed into her eyes at once, causing a headache to emerge, the dragoness’s skull throbbing in time with her heart. She persevered, squinting with blurry vision; everything was indistinct. The room was large and appeared quite medical, scientific even, cluttered with desks and tables and cabinets with machinery scattered around. That didn’t exactly make Seracen feel any better though. The air was filled with the scent of chemicals and cleaning products, but underneath it was something far more worrying.

She could smell other dragons and not just that, but horny, in-heat dragonesses. Her vision getting clearer, the shape of a tube resolved itself. It was attached to the thing in her muzzle and rose up. Tilting her head back, Seracen spotted it disappear into the ceiling…besides two other tubes. Eyes widening, she twisted, giving a small yelp into the gag. The black dragon was between two other dragonesses, both seemingly asleep. The one on her right was white and furred, with black patches around her eyes. This ness was twitching slightly in her sleep, but making no noise.

On Seracen’s other side was a golden-furred female. She was making quiet huffing whines into the gag, hips twitching at the air. All three dragons were reared on their hind legs, something it had taken a few moments for Seracen to realise. There was no strain from the position; normally it would be quite difficult to stand like this for any length of time. Now though, it almost seemed like something was holding Seracen up, though her hind legs seemed to be stuck to the floor in a spread position.

As for her forelegs, the black dragoness twisted, looking down at her body with wide eyes. A tube of latex had been put on her body, forelegs trapped beneath it close to her chest, almost a begging position. The other two females had the same thing. A little panicked now, Seracen strained, trying to free her arms. The latex stretched less than an inch, not even making a sound, before it forced her legs back against her chest. The most she could do was squirm helplessly. Taking in deep breaths, she tried to calm herself enough to use magic, closing her eyes to concentrate.

Seracen breathed in deeply, feeling the magic well inside her…and then nothing. The latex around her seemed to suck it out, prevent her from using her power. She tried to shift instead but even that was impossible and she gave an anxious whine, looking around. Maybe they can help me? The other dragonesses were both asleep, and looking only made Seracen feel worse. There was a pole behind either of them, keeping them upright but that wasn’t the concerning bit. The latex ended right above the dragonesses’ sexes, keeping them exposed to the room. More importantly, they were swollen with arousal and heat.

The golden furred one had a plastic cup sealed around her pussy, for what Seracen didn’t know. It didn’t seem to be doing anything but inside, the poor ness’s pussy was swollen and red, even more than usual. For the ness on the black dragon’s other side, there was an empty bowl beneath her. Nestled in her folds though, right over her clit, was a purplish object. Seracen had no idea what it was, but she instantly didn’t like the look of it. This whole situation seemed ominous and wrong.

She howled through the gag, hoping someone would hear and come to help them. At the same time, she began to struggle, yanking on the weird latex straitjacket while trying to squirm off of the pole. Seracen made enough noise that the other two woke up with a jerk, looking around wildly for a moment. The newly-woken dragons spotted Seracen and looks of concern and sympathy crossed their faces. “Mmmmph,” the white one said into the gag soothingly, her furry tail moving over to rub against Seracen comfortingly. The other dragoness did the same and Seracen stopped struggling with a whine.

“Ah, I see you two have met your new ‘sister’!” a voice crowed, all three dragons jumping, Seracen immediately looking for the source. A human — of course it was a human! — was standing by the door on the opposite side of the room. He looked remarkably unremarkable, with a close-cropped beard and a labcoat.

“Mmmmnnnph!” Seracen growled into the gag angrily, glaring at the human. How dare he kidnap three dragons! And what’s he been doing to them?!

“Ooh, a feisty one,” he smirked. “Always good to start off that way.” The other two dragons whimpered and whined pleadingly as he approached a control panel on the wall, flicking a switch. Seracen watched, wide-eyed and looking between them, as they both moaned and began squirming and twisting on the pole keeping them in place. The hum and buzz of machinery filled the air, quickly becoming background noise. At the same time, something began to fill the tube, dripping down Seracen’s throat. She gagged, but there was no choice but to swallow it, the dragoness blushing; the motion made it seem she was suckling on the gag.

“Don’t worry about that,” the man said, motioning to the tubes. “Just a mixture I make myself. Nutrients, water, a couple of other compounds…proprietary dragon feed, you might say.” He laughed, smacking his leg in mirth. “Keeps you a little weaker and more complacent too, along with some other side effects.

At that Seracen tried to stop swallowing it but she couldn’t, having to gulp it down so she could breath. “So,” the man continued, “I guess I should introduce you to your new friends. The white is Crystal; the tan, Hyrona. And you, I believe, are named Seracen, yes?” The black dragoness growled muffledly, the scientist accepting that as consent.

Seracen growled louder but took a moment to look at Crystal next to her. The furred dragoness was moaning and whimpering, forelegs tugging at the latex covering them as she squirmed. There was a steady dripping sound and Seracen glanced down, blushing powerfully. The purple thing on Crystal’s sex was a vibrator and had activated. The dripping sound was the steady fall of the dragoness’s juices falling into the bucket below her, a small hole draining them away slowly. More than that though, her pussy was beginning to swell like she was going back into heat.

The black dragoness looked to her other side next and moaned again, blushing harder. The cup around Hyrona’s pussy was applying suction, making her folds get even more engorged and larger. Her juices were being whisked away as well but there was nothing that Seracen could see making her squirm and moan like she was.

“Ah, yes,” the man smiled. “An explanation, perhaps? Well, it’s quite simple. Your new friends here are, like you soon will be, being perpetually denied. A dragoness’s arousal has quite a few uses, but it’s better if they are born from denial instead of relief. Hence, neither Crystal or Hyrona have cum since they’ve gotten here, have you, my dears?”

Crystal flicked an eye open, looking at Seracen for a moment with a whimper and nodding slightly before shuddering and moaning again.

“More than that,” the scientist continued evilly, “they’re teased non-stop for sixteen hours a day, and almost all of that edged. Then there’s the heat. Can you feel it yet, Seracen? A little drug in your feed. Quick acting…”

Seracen was straining and growling, wanting to get free so she could hurt this man but at those words, she froze, her only movement continuing to swallow the slow trickle of fluid from the gag. Now that her attention was being drawn to it, she could feel a little warmth running through her body. She groaned into the gag, hoping it wasn’t true, but the warmth slowly settled in her crotch, the dragoness’s sex slowly reddening.

“Ah, there we go. Don’t worry, the need will come soon. I have something special in mind for you, but you should see your sisters’ predicaments first.” He picked up a handheld mirror from a desk, placing it so Seracen could see Crystal’s pussy from other angles. “As you can see, Crystal’s main stimulation comes from this little thing.”

He reached out, nimbly holding the little vibe between his fingers. As he pulled it to the side a little, Crystal made a breathy squeal, hips twitching a little. As the vibe was moved though, Seracen spied that it was a piercing, metal bars moving right through her nub. “As you can probably see, this is attached to her,” the human said, sounding rather proud. “The vibe is smart; it gets stronger or weaker to ensure she never actually cums, but the piercing helps distribute the sensations through more of her sensitive areas than if I simply taped the vibe on, for example. But, she loves it.” At that comment, Crystal whimpered, a splash of her juices falling into the bucket. Already she was beginning to produce more, the drips becoming a steady trickle.

“Oh good,” he said, parting Crystal’s pussy with his fingers. “There are chemicals in the feed to increase you girls’ production, but the edging does wonders. Other than the vibe, there isn’t much that I’ve done to her. Apart from this.” He manoeuvred the mirror again and Seracen say a black circle right beneath Crystal’s tail. “This is a sizable plug. Vibrates too, pretty powerfully. Crystal here can’t climax on anal alone so it never really shuts off or lessens.”

The horror was rising in Seracen and she growled louder, even as her own pussy reddened slowly, the chemicals doing their work. Thrashing made her feel better but she was no closer to being freed and seeing what was being done to these other females… If they haven’t escaped, what hope do I have?

“Ah, and Hyrona!” The man moved over to Seracen’s other side, the black dragoness’s head following him. Her leg tensed as she tried to kick at him, but her paws wouldn’t move from their spot on the floor. Hyrona moaned and humping into the cup, her pussy so swollen it filled half of it.

“This is an interesting experiment. This dragoness’s sex gets much larger under the suction, as you can see, and a lot more sensitive. As you might be able to see, there’s a small ring around her clitoris. That’s magical and prevents orgasm. That way, I can stimulate her as much as I want and not have to worry about her cumming.” A powerful pulse of liquid fell from Hyrona’s pussy to land in the cup, along with a long whimpering moan. Her juices were whisked away at once.

“She does that. It’s not an orgasm, I’ve made sure. More like really needy squirting. Crystal does it as well, just takes longer for her.” His voice got low, almost conspiratorial. “Do you want to know what’s stimulating her? It’s about two dozen of these.” He held up a tiny metal ball. “They’re magical vibrators. Did you know that the female clitoris is actually quite large? The bit you see is only the tip; the rest of the organ extends deep inside; that’s what the g-spot is. Well, Hyrona has had a lot of these vibes implanted into her flesh. Around four just in her folds, near her clit, or the part you can see, and another four around her g-spot. The rest are all along the internal sub-structure.

“It’d be a pleasure so complete and overpowering…she can barely speak when they’re all going. If she didn’t have that ring, she’d cum in a second, and wouldn’t stop. That might be fun…but not what the experiment required. Even if she did get out, I bet Hyrona would come right back…there wouldn’t be any pleasure close to what she’s getting now.”

Seracen whined, looking at Hyrona in horror as the furred dragoness twisted and squirmed, eyes unfocused and wordless pleas and whines escaping her muzzle. Hyrona seemed consumed by the pleasure, unable to even think clearly.

“She loves it,” the man said dismissively. “Should hear her beg when it’s turned off in sixteen hours. All she wants is for it to continue.”

Probably because you’ve edged her for a day, monster, Seracen thought, growling.

“Oh, and this.” The scientist angled the mirror again so Seracen could see the thick plug filling Hyrona’s tailhole. “Modelled after a nice equine cock, just…scaled up. Quite a stretch, but it’s her favourite by far. Here…” He grasped the base and gave it a hearty yank, Hyrona moaning louder. About half of a foot of thick horse cock slid out of the dragoness. So wide… Seracen thought, amazed and horrified. How can she hold it?

“This isn’t even half of its length,” he boasted. He thrust the equine length a few times then pushed it up again until only the base was visible, the rest of the massive length locked away in Hyrona’s tailhole.

With that, he stood back, spreading his arms as if he’d announced a wonderful show. Seracen snarled at him instead, latex stretching and reflecting the lights above as she tried again to get free. “Oh, I forgot,” he said, smacking his forehead lightly. “You’ll want to begin your regimen too, I suppose.” He winked. “I have a few ideas.”

He went to the far side of the room and grabbed a cart, smoothly rolling it over on wheels. The front of the cart was a series of drawers and cupboards of varying sizes, no doubt storing all manner of unpleasant things. Seracen stared at it apprehensively, not knowing what to expect. Considering what had happened and what was still happening to Crystal and Hyrona, it wouldn’t be anything good.

The first few movements were not a good sign. The man pulled out a bottle of thick lube, opening a large drawer a second later. “Might start with a plug,” he mused to himself. His body blocked the contents but he rummaged around for a good minute.

Plug? Seracen didn’t like the sound of that and her tailhole tightened subconsciously at the thought, a whine making its way through the gag. The black dragoness’s tail lashed as the scientist held something up, her eyes widening in not a small amount of concern. The plug he was holding up was a large dragon dildo, one with a healthy knot at the bottom and a line if ridges running along the underside. Even in her sex it would be a bit of a stretch, never mind her ass.

Smiling widely, he gave the lube bottle half a dozen healthy pumps, coating the ‘plug’ liberally with the thick gel. “I advise that you relax,” he said, walking behind Seracen. The dragoness tried to hit him with her tail but the pole was in the way, her tailbase on the wrong side. The most she would do was swat at him with the last third, the weakest part of the limb without any good angles. As such, the human pushed her tail away, setting the pointed tip of the toy against the dragoness’s tailhole.

Seracen groaned, Crystal whining as well as she watched the human add pressure to the toy’s base, slowly forcing it in. As much as the black dragoness tried to clench and keep it out, that caused it to hurt and she had to relax, making it easier for the human to push the toy into her. “That’s it, accept it,” he smiled. Seracen moaned and squirmed as the ridges moved into her one after the other, the entry made pretty easy by the premium lube. Still, it was quite the stretch and she was grateful when he stopped, at least until the dragoness realised that the knot was next.

The dildo was held still for a few moments, letting her adjust. Seracen panted, her body clenching down on it a few times, feeling the tip and ridges deep inside her ass in a way that made her pussy shamefully wet. She moaned in surprise when he human twisted it idly inside her, panting as that seemed to make the warmth in her sex intensify, her heat slowly making itself known.

“Knot now,” the scientist said dispassionately and began to push harder, grinding and twisting the toy. There was still quite a bit of lube on the knot and it began to sink into Seracen, despite her whines and muffled protests. A few seconds later, with a small pop, the knot disappeared inside the dragoness with a sharp stab of discomfort that made her yelp. Now only the base of the dildo was visible. She felt so full; her body immediately tried to expel the toy but the knot was too large. Unless the human wanted it out, she’d have to get used to the feeling of a stuffed tailhole.

“Very good!” the human crowed, before clapping his hands. “Right, so on to the fun stuff. Let’s see…oh, I’d like to use these…”

From a drawer, the human pulled out a bunch of hemispheres, holding them out on his palm. “These are remarkable little machines I invented a while back,” he explained. “Should be very interesting…”

Even Hyrona had gathered herself enough to watch this, though she was still humping and moaning. Crystal was whining, her own hips twisting, both producing large amounts of arousal, fully in heat now. Seracen was well on the way there herself, a fire beginning to burn in her belly and few drips falling from her folds. In spite of herself, Seracen found herself looking at the little devices with a hint of curiosity. They were a light grey metal and all perfectly identical. About a dozen lay on the man’s palm and he took another dozen out of a small box with his other hand.

“Go get her, boys!”

He flung the little things up but they didn’t go far. They all stopped abruptly in the air, levitating magically. Seracen twisted and looked down until the tube tugged on the ceiling, unable to extend any further. Giving an anxious whine, she tried to keep them in sight but that was impossible. They drifted towards her sex slowly, almost as if they knew that the slow progress was making it worse.

Even though Seracen couldn’t see, Crystal and Hyrona could. They watched as a few of the machines merged together, their shapes turning amorphous, like a liquid in freefall. Suddenly, it all shot forwards and Seracen howled, feeling it hit her pussy. At once, the machines, now all merged together, began to spread. They noosed around the base of her clit before enclosing it in a dome, tight against the nub and squeezing it from all directions. Seracen whined at that, humping her hips to try and dislodge it but failing.

The next step was even more invasive. The dragoness howled into the gag, partly in discomfort and mostly in shock as a little bit of the odd material slid into the dragoness’s urethra, not going in far but thick enough that it was uncomfortably apparent. Seracen twisted and gyrated at that, trying to shake it loose but no more successful than before. And still the amorphous toy moved. With her clit covered and urethra filled, it moved to her entrance next, pressing a thin spire into it and extending deep inside her.

The thin length only served to make Seracen more needy. With her heat, she wanted something long and thick, thrusting with ridges and knot inside her until she came explosively. Her pussy clenched around the spire but that only made the heat worse; it was so thin it seemed barely there. Even so, Seracen’s pussy tried to milk it, clenching hard as her walls rippled around it, the spire growing deeper. The dragoness gasped through her nose as it suddenly grew a wide ring inside her. The sensation of being spread in that one spot made her whine, humping at the air before she regained control over herself.

The dragoness promptly lost it again as the thin spire suddenly moved hard against her g-spot, prongs pressing into the extremely sensitive place inside her. When she clenched down, they pressed in even more firmly. Seracen was well and truly wet now but the process still hadn’t stopped. The loudest yelp came when the machines suddenly pushed against the dragoness’s cervix. Her heat made it slightly easier but it was still greatly uncomfortable as they forced their way in, keeping the entrance to her womb spread with a small ring.

“Right, that’s about done by now,” the scientist said, right on time. “Time to set this up. He brought out a funnel on a tube and locked it into a pipe on the floor, right between Seracen’s hinds. Then the human extended the pipe so that the funnel was right beneath her sex, already catching the drips of her juices that were falling. The scientist double checked everything, then nodded to himself.

“Yep, you’re ready,” he said to Seracen with a broad grin. “I have a feeling that you’re going to be an excellent producer, even better than Hyrona!” He winked and picked up a small tablet from the cart, tapping the screen.

Seracen convulsed, howling into the gag. All of the most sensitive points in her body seemed to light up. It seemed a mix of electricity, vibration, and movement that turned into an indescribable sensation. Her clit and urethra were focused on but her g-spot was given almost as much attention. Every now and then the spire would ripple, a portion of a little more thickness running up it. She couldn’t stop clenching around the dildo in her tailhole, wishing it was in her sex instead.

Inside her womb was where the strangest sensations were coming from though. It was vibration and sparks of electricity that made her squirm and moan. The dragoness was unused to all this and so unable to resist it or block it out, especially the feeling from inside her womb and urethra. It didn’t take long before Seracen approached a climax, reaching the edge quickly with the assault inside her. Only…she couldn’t reach it! The stimulation didn’t lessen or change; it just seemed perfectly calibrated to take her to the edge.

She howled, sex clenching as a squirt of her arousal fell into the funnel, more drips and trickles following it. Seracen’s heat was in full force now and she was producing at a steady rate, thanks to the teasing and drugs in her system. The black dragoness joined Crystal and Hyrona in jerking and twisting, filling the air with the sound of their cries and the smell of their heat and arousal. It didn’t take long before Seracen began to ignore the human, too preoccupied with the maddening need in her pussy, and her inability to cum.

The scientist yawned, scratching at his beard. “Think I need some coffee,” he said to no one in particular. He smirked at the three moaning, desperate dragoness’s, noting that the canister behind Seracen was already filling at a nice pace. It wasn’t as fast as the other two, but her body would produce more faster and faster now. “Don’t you girls go anywhere,” he said, then left, roaring at his own joke and leaving the three to their frustrating teasing.
