Another story in the parasite infestation series, this little tale shows what happens when Ailsa goes to the doctor and has a few ideas of how to expand the hive. Lots of little worries there, if she can make sure that she doesn't get caught by the military...and maybe that doctor might be useful, too.

An Opportunistic Exam

For Kacacarrotcake

By Draconicon

The apartment block was not as well-populated as her host remembered, but Ailsa managed to collect two more hosts on her floor that afternoon. It wasn't as much as she had hoped to get, but in hindsight, it was better to take her time and collect them one by one than to try and convert the entire building and likely get caught by someone passing by. The way it went, she had been able to infest two people over time, silently, and nobody else had been any the wiser for it.

The stingray had returned to her apartment, still getting used to the feeling of the new body. Though she had changed most of it to reflect her preferred state of being, there were still a few small bits and bobs that were off from her original body. She was still shorter than she had been, and there wasn't quite as much mass in her chest and ass as she'd like, but it was better than nothing.

The sting in her tail was still missing, too, but that was something that she could live with. Better to use it as a secondary means of infecting people at the moment, rather than to use it as a defense.

Ailsa shut the apartment door behind her, leaning against it and taking a few deep breaths. The sense of things wriggling around inside of her, of the new parasites starting to bulge in her belly and exploring the inside of her hollow shell made her smile, and the sight of a few bulges running along the inside of her throat made her grin all the more.

It was working. She was gradually becoming a good queen again, breeding more of the parasites. She'd taken in some of the new swarms that the first guy - the dolphin - had created on the way back from her second convert, and he had filled her with another ten parasites. He'd probably be burned through before too long, his body eaten away by the rapid breeding of more of the hive, but that was an acceptable loss if it replenished the hive properly.

She ran her hand down her belly, feeling the parasitic creatures inside swelling upwards, following her touch, the hive mind that they shared reminding her of her duties as the queen. Another reminder that they followed because they chose to, a reminder that she could be replaced if she did not give them what they needed.

I will, I will, she thought at them. The hive will rise again. The colony would grow.

Not all of the other hosts that she had set up during their get-away had come back to life. There had been some parasitic swarms that had managed to come to life again, but most of them had been consumed by the insides of their hosts before they could come back. She had very little to work with...

But there'd be enough. She hoped.

Ailsa sat down on the couch, shaking her head -

Ring ring. Ring ring.

"...Who the hell..."

She had almost forgotten that phones were a thing, and she had to look around to find it as it kept ringing. The stingray eventually found the button for it under the couch cushion - must have slid down there somehow - and pressed it. A hologram popped up, and a light shone under it, indicating that she was being video-transmitted to the other end.

"Hello?" Ailsa asked.

"Confirm identity, please," the voice on the other end requested.

"...Hanna," she said after reminding herself what her host's name was. "Hanna Thompson."

"Identity confirmed. Please hold."

You called me, and you don't even have someone waiting on the line? She shook her head. People never change.

Thankfully, she was only on hold for a few minutes before someone replaced the static blue hologram. It was a male husky, one that looked like he had been running to the phone and dressed in a white doctor's coat, one that ran down the length of his body.

It suddenly made her aware that she was still naked, and she held the communicator up a bit higher, just to make sure that it didn't go below her neckline and show off her breasts. A doctor might actually see the lumps in them and know what they meant.

"Hanna, good to see you again," the husky said. "I got a note from the military saying that you needed to get checked out. Something about an infestation thing?"

Shit. She'd thought she'd gotten away easy, but she should have known that the administration wouldn't just let this go. And this doctor seemed to know her host better than just a standard caregiver. She searched through the host's memories while responding.

"Uh, yes. I was at the spaceport during the...incident. I guess they want to make sure that nothing happened to me."

Infestation. That would mean they found something. Maybe something big enough to blow my cover, but if I can keep this quiet...

There wasn't much information in the host's brain, unfortunately. She'd done too good a job at scouring it to make sure that it didn't bother her, and it had left too many blank spots. She did have a name, though.

"I must have done something to my head, though, because I'm feeling...weird. Dr. Vesi, can you remind me how to get there?"

"Sure. Let me send that over..."

Getting the ping of a file arriving, Ailsa resisted immediately opening it to verify her journey. She knew better than to look paranoid and too forgetful. That would only encourage this 'Dr. Vesi' to give her a closer examination, to go deeper. If she didn't keep control, he would find things that she definitely didn't want him to find. The breasts and ass and tail were going to be hard enough to explain.

"I'll be there as soon as I can."

"You sure? The military did offer an escort -"

"No, I'll be there myself. No need for them."

Ending the call perhaps slightly quicker than she should have, Ailsa got to her feet and walked over to the far side of the room. The stingray looked down from the window, feeling the fading sunlight on her breasts, the warmth of the evening fading towards the coolness of the night. It was a lovely feeling, and it made her wish that she could stand there, showing off to any idle viewer for hours.

But if she didn't go to this appointment, if she didn't get cleared by the doctor, then she would be more than pressured. She would be arrested, quarantined, and eventually - not quickly, but eventually - discovered as the queen of an alien hive of parasites. The minute that they figured that out, the moment that they had proof, she would be destroyed, and so would the colony and hive that she needed to protect.

No, she had to get this done properly...and if she did it right, she might just have a whole new potential set of converts.

Her lips turned up in a smile as she spun about, collecting her clothes so that she could arrive in a less shocking, inappropriate state.

The ride from her apartment to the doctor's offices was an uneventful one, though a bit of a hair-raising thing considering that she kept having to pull memories that were half-destroyed from the depth of the host's mind. There were bus routes that would take her hither and yon, but she didn't have time to learn them. Nor did this particular host have a vehicle of her own; the planet had done away with many of them in the time since Ailsa had last been planetside.

As a result, it took her far longer than it should to reach the white-metal building that the doctor kept his offices in, leaving her almost late. Several soldiers stood outside the building, their rifles held up at their chests, but their eyes were sharp and hard as they looked at her as she passed by.

They're here for me, she knew. Just in case I didn't show up. Just in case I'm dangerous.

She entered the waiting room, which was completely cleared. Another sign that the military were involved in this particular examination, she knew. There was no way that any clinic would be this empty on a weekday, not when there were always people that were sick or injured.

The stingray walked up to the receptionist, a mousy rat that looked up through glasses that were too thick and dark for her to see through to the other side.

"Name?" the rodent asked.

"Hanna Thompson."

"Don't see any Hanna last name."

"...Thompson is the last name, Hanna's first."

"Ah, right, right. Sorry. Misunderstood. Sit down. Doctor will be with you shortly."

In other words, the same as always, despite the fact that she was the only one here. Ailsa shook her head, taking the seat nearest to the door further into the clinic. It wasn't ideal, but it would look better for her to be antsy to be examined rather than itching to leave.

Still, her tail twitched behind her and the gills on her neck flared slightly before she forced them back down again. The stingray queen reminded herself that there was nothing that would come up on a scan, and she would likely be alone with the doctor for some time. The military could only do so much to control the situation.

Just remember to check the room for bugs, she thought. If they spot anything that you do, then the whole plan is foiled.

The stingray took a few deep breaths, feeling the creepy-crawlies sliding around inside of her. Some of them were dropping down to her slit, running along her inner walls, while others were sliding into the base of her dicks, starting to swell them and push them forward. Clamping down on that to keep from getting a pair of erections that she wasn't supposed to have, 'Hanna' pulled her hands together over her lap and closed her eyes.

A few minutes passed, and the doctor finally appeared. The husky was a taller canine, standing about a head over Ailsa's host, and he looked slightly chubby compared to some of her other partners. He smiled at her as he turned, his coat pulled tight to hm, almost more like a flowing jumpsuit than an actual coat.

"Hanna?"

"Yes?"

"Come with me."

He nodded over his shoulder and she stood up to follow him.

More signs of the military's interference could be seen in the other rooms. All the doors were open, and while there were people in them, it was clear that they weren't doctor and patient. The way that they were staring at her, the way that the eyes followed her everywhere she went, told her that they were just undercover folks, people meant to make this place look like it was a functioning clinic while still keeping an eye on her.

The more that she was around this Dr. Vesi, the more that she realized that he was nervous, too. Not in the way of someone that was lying, but in the way of someone that didn't know what was going on.

Heh...perhaps I should enlighten him if there's enough privacy...

They finally reached the exam room, and the husky held the door open for her. A quick glance around the room - and a bit of echo-location from a few surface-level parasites - confirmed that there were no bugs stuck to the wall or just behind them. There might be others, but she doubted that they'd be strong enough to pick up what she was doing.

Looks like they're relying on the doctor screaming his head off...or they're looking to find evidence of what I am after I take him over, she thought, puzzling out what she wanted to do as she got up on the exam table in the room. If I do this right, I get an ally. If I do this wrong, I expose myself. Careful.

Ailsa-Hannah leaned her head back, looking up at the ceiling before Dr. Vesi cleared his throat. She brought her head back down, cocking it to the side.

"Yes?"

"Could you, erm, pull your shirt up? We'll start with checking your heart."

"Heh, sure."

She knew that she was being slightly more flirty than Hannah would have been - or she guessed she was, considering the look that the husky was fixing her with - but she couldn't quite help herself. It felt good to show off.

As she pulled off her shirt, she lingered with it over her head, letting the doctor get a good look at her enhanced breasts. Considering that she hadn't bothered wearing a bra, she guessed that he was getting something of an eyeful. No screaming, either, or any pushing for her to cover herself. Either he was enjoying it, or he was pushing himself to stay professional.

When she was able to toss her shirt to the side, she leaned back a bit further, not quite in the way of a porn star, but definitely showing off more than she had to.

"Is that good, doctor?"

"Uh, yes, um, very...very good."

He fumbled with a stethoscope - something of a holdover from the old days - and pressed the cool metal to her chest. She smiled at him, leaning forward with a sultry grin, letting his hand slide along her bare breasts. He felt nice.

And he was getting something of a hard-on, which was even nicer.

Chuckling, she reached down with one hand, rubbing his crotch. It was something that Hannah never would have done, she knew, but the doctor didn't pull back as she squeezed his bulge.

"What's the matter, hmm? You look rather...tense."

"This is...very inappropriate."

"Yes, but you like it."

"Hannah, are...are you okay?"

"Hmmm, for the most part. Just..." What would be good to say? Oh, yes. "Just feeling a bit...needy, after that near-death experience."

"Well, that's, um, that's completely understandable..."

He was nervous, too, very nervous, and only the natural libido of a normal person kept him standing where he was. She imagined that he wanted to know what was going on, and that need to know was warring hard with the need to get more attention down there.

She pushed her luck a bit, flicking at the button of his trousers, letting his cock flop out. Knotted and tapered like a good doggy dick, it bobbed in front of her. He blushed, starting to take a step back, but she hooked two fingers around the base of his knot, pulling him back to her.

"Ah ah. I didn't say you could leave."

"Hannah, this is...this is extremely inappropriate. You should be dating or something, not doing this with your doctor."

"Oh, would it be that bad for you to take a bit of fun?"

"You're still at risk. You could be carrying -"

"How about I make you a deal, doc?"

The stingray smirked, turning around, getting on all fours on the exam table. She could feel his eyes watching her, feel him staring at her ass as she rolled it about in her short skirt. Her tail lifted just enough for the doctor to see that she didn't have any panties on, that she was holding herself back from the world with just that barrier of cloth.

Then she looked over her shoulder at him, seeing his cock bouncing like a dog eager for a treat. She chuckled.

"I'll make you a deal. If I'm clean, then you give me what I want. And if I'm not, I'll give you a show, hmm?"

"..."

"Do we have a deal, Dr. Vesi?"

"Tempting..."

"Heh, we can even make it an after-hour deal, if that'd make you more comfortable."

"That...would..."

"Then it's a date. Check me out, doc."

He gestured for her to lie back, and Ailsa did just that, spreading her legs and letting them rest on the far sides of the table. Her willpower was the only thing that kept her cocks from jumping out and revealing one of her secrets, but that was fine.

She had a prize coming, and she was going to earn it.

When she was released from the clinic, she was left alone for a while. Not long, not much more than five minutes, but it was enough for her.

Ailsa smiled as the doctor left the room, probably hurrying down the hallway to clear his head, likely to be ambushed by members of the military that wanted a full debriefing of what he had found out. She knew that he wouldn't mention their little 'date' to the soldiers. Not without risking losing his own position for abusing doctor/patient privilege.

At the same time, she knew better than to trust someone to keep their mouths shut. Better to get out as soon as possible...after seeding the place.

The stingray backed herself up to the corner of the room, right under one of the ventilation ducts. She squatted down, her tail up, her cheeks spread, her hands rubbing along her thighs and over her pussy as the little worms came.

They were little more than little maggots of things, tiny and short, but there were dozens of them sliding out of her, the parasites immature and needing a place to grow. The warm vents and the spacious darkness above would give them all they needed, she was sure.

They wriggled as they slid out of her, coming down over her pussy and out of her ass before dropping to the ground. She moaned and hissed at the feeling of their ridged bodies wriggling against her, out of her, and she sighed happily as she felt each one pop free, sliding out of her depths and into the real world.

It was scarcely more than three dozen of them that came out, but that would be enough. The little ones would find hosts when the doctors and nurses came back to the clinic, and then they'd have the chance to start spreading the hive among patients that were here, trusting their doctors to have their best interests in mind.

The hive would grow.

She had barely gotten back to her feet, her skirt smoothed down before Dr. Vesi returned to her. The husky smiled, slightly red-faced as he nodded at her.

"You're free to go. Shall I walk you out?"

"No, I can find my way."

"You sure? I don't mind."

"I'm sure." She smiled. "But you can give me your number."

"Oh, right. I had, uh, I had forgotten that."

He pulled out a little pad, scrawling on it in the way of doctors since time immemorial, and then tore it free to hand to her. She pocketed it between her breasts, which only seemed to make him blush that much more.

"I'll see you later, Doctor."

"Uh, yeah, uh, I'll see you too."

She smiled, giving him a pat on the cheek before leaving the exam room.

Whatever other staff members had been around had obviously been cleared out by some command from higher up. Ailsa didn't know what had happened, but it seemed that they had cleared her, too. Nobody tried to stop her, and she didn't feel anyone staring at her at any point as she left the building.

Maybe that'll be all I need to do...

Somehow, she doubted it. The obvious surveillance was probably pulled, but she imagined that her phone lines and other methods of communication would be tapped for some time to come. If she wasn't careful, then they would still get the evidence that they needed to pull her off the streets.

But she was a hive queen. She was getting used to being careful.

She left the building, caught a taxi, and took it to one of the public parks that littered the city. Part of a greenery initiative to bring some of the natural beauty back to the planet after a great deal of it was destroyed during the colonization rush, it was little more than a big lawn with a tree perimeter. The one good place that it had was the hedge maze, and that was browned from lack of care.

Still, it had cover there, and it was all she needed for her plan.

Ailsa made her way to one of the public phones, dialing Dr. Vesi's number. The husky took a few rings to pick up, but when he heard her voice, he was eager enough.

"Come down to the park. First one east of your office. There's a hedge maze. Meet me in there."

"Uh, okay. Are you sure that this is a good idea? I mean, if you're even slightly worried about this -"

"I'm not. Just get your ass down here as soon as you can. Besides, it's more fun doing it in public."

"I...I'm not going to argue there..."

She hung up, the stingray chuckling as she walked towards the hedge maze. It wasn't just good for hiding. It was good for making something of a nest.

After all, she could always do better than keeping just one host.

The stingray let more and more of her creatures run free, worms and slithering creatures running from her holes, and legged things pouring from her mouth. She stripped herself of her shirt and her skirt as she walked, letting the creatures pour free from her nipples and her fingers, from her nostrils and her gills. Any orifice that they could find, they used, and she was happy to let them do so.

Soon, she was completely naked, barefoot and exposed in the center of the hedge maze, and all through the dead plants, she could hear, feel the different members of her hive finding their places. Some wove webs, others created nests of slime. Some perched themselves on branches, waiting to strike in quick, painful ways, while still others created little roofs of greenery, or hatches in the ground, waiting to pull down those that came by.

All of them were ready for hosts of their own, eager to expand their little colony, make it bigger, better.

But Dr. Vesi was hers. She made that very clear in her whispers to the various parasites, and the parasites allowed her the decision. She was the queen still, after all.

They subsided as the sound of someone approaching could be heard. Ailsa was informed at the center of the maze that it was their husky visitor, and that he was alone. The hundreds of eyes and feelers and antennae that littered the maze were feeding her information at an astounding rate, and she grinned as she 'saw' the doctor as he walked in.

He had changed to jeans and a t-shirt, little more than casual street wear, with boots that covered his feet. Not combat boots, but something that looked like them. She didn't mind that. It would be all the more fun to rip it all off of him.

Oh, and he was bulging, still. He must have remembered the way that she treated him back at the office and hoped for more. Well, she was certainly happy enough to give him that. The stingray leaned back on the stone table in the middle of the maze, her legs already spreading in anticipation, the scent of her need already filling the closed area of the maze.

The husky never new the danger in which he lay. He didn't know that there were hundreds of parasites that wanted his body, that wanted him. Oh, they would have ripped him apart, stuffed him full, and then sewn him back together if Ailsa had let them...

But she didn't. Not now, at least. She had plans for him, and those plans couldn't be completed if he was ripped apart.

Closer and closer he came, and she heard his voice calling her name. Quietly, of course, never more than a whisper. He obviously was worried about being fooled, about being overheard. It was rather cute, in a way. He was so nervous that she almost felt bad about consuming him, filling him, taking him.

Almost.

She spread her legs as far as they could go, still suppressing her cocks as he entered the middle of the maze. He paused, staring at her, his eyes wider than she had realized a husky's eyes could go.

"Hannah?" he whispered.

"Mmm?"

"You...you..."

"Heh, you want it, I know."

"I didn't know...well...I didn't know that...you did..."

"I always want this sort of attention. Why don't you come a little closer?"

There was no question of whether or not he was under her spell. Perhaps it was still a hint more her beauty than her pheromones, but he was obviously having a hard time resisting her. Perhaps he didn't even want to.

As soon as he was within reach, she lashed out. Her tail slapped against his legs, pulling him closer, while at the same time grabbing him by the mouth. The sudden scream was muffled against the palm of her hand, and she smirked up at him as he squirmed, trying to pull back.

"Oh, you poor man...did you think you were going to be on top?"

Her smile twisted as the parasites pulled themselves up to her mouth, finally giving her back her many tongues. They pushed past her lips, twisting, writhing, squirming against one another in an attempt to get at the doctor before she pulled them back.

Wait your turn...after I have him...so shall you.

As he kept trying to scream, she turned him around, forcing him down on the stone table. Her fingers curled, tentacles and parasitic worms pushing free of the tips, working their way forward and using their mandibles like claws, ripping through cloth and denim until the husky was stripped of all his clothes.

He was naked, naked as the day he was born, and he had quite an ass to be showing off. She licked her lips at the sight of it, smacking one cheek and watching it jiggle.

"Mmm, you should have let me examine you."

"Oh god, what are you? What the fuck are you?"

"I'm...complicated."

She chuckled, letting her cocks finally pop free of their hiding place. The sound of them coming loose from her tight flesh was probably louder than it needed to be, but it was probably the touch of the hard, hot rods that got the husky's attention. He whipped his head around, looking behind him, and his eyes looked like they were about to pop right out of their sockets.

"Oh fuck, oh fuck, get those away from me!"

"Not a chance in hell."

She grabbed them by the base, pushing them together with one hand while her other extended more powerful, longer parasites like tentacles from her fingers. They wrapped around and about the husky, keeping him from getting up, keeping him from running away.

The temptation to thrust one down his throat was there, but she decided against it. This deep in the hedge maze, there was no one to hear him scream. And besides, it would be more fun to shove her parasites up his ass rather than down his throat. More...fitting, in a way.

Smirking, she tapped the tapered tips of her cocks against his asshole a couple of times, feeling him clench, feeling him trying to pull it further in so that she couldn't access it so easily. She didn't give up, pushing further in, feeling his hole clenching and sucking in on itself, his whimpers filling the air as he continued his futile attempts at escape.

Though she could have savored his struggles for hours, she knew better than to push her luck. On the off-chance that the military was still directly following the doctor, she needed to have him under her control, now. She grabbed him tighter with her parasite tentacle fingers, pulled him back...

And felt the soft pop of his ass accepting her twin dicks.

She groaned as he screamed, her breath coming faster, her many tongues hanging out of her mouth as she felt him squeezing down on her cocks, pulling at them, sucking them into his hole. Oh, he was still trying to push them out, still trying to wriggle off of them, but there was something intense about the way that he was doing it. Little wriggles, tight squeezes, hot walls rubbing all along her shafts...

Yes, that was what she missed. That was what she hadn't had in all too long.

The stingray thrust herself into him, feeling him gasping beneath her, breaking, shifting, cracking. He grunted every time that she bottomed out inside of him, feeling him groaning, shivering. His back arched as her cocks found his prostate, and she made sure to spend some time there, grinding away, pushing him, nudging him with pleasure that he didn't want.

In and out, in and out, each thrust opened him up that much further, and Ailsa's cocks were teased and pleased in entirely different ways. She gasped every time that the husky clenched down on her, moaned under her breath every time that his fat ass jiggled and caressed her cock in a different way.

"Yes...that's it..."

She smiled as she leaned forward, almost laying over him as she fucked him. She wrapped both her arms around him, holding him down, holding him to her. Her breasts squished against his back, and her nipples spread - spread so painfully pleasurably far - as more of the creatures slipped from her.

"Give in...give in to the pleasure...give in to me..."

She smiled, wrapping her tongues around his head, two diving down his ears, others holding his muzzle shut.

Give in to the hive...

Two, three, four more thrusts, and she could no longer hold back. Her balls pulled up on the inside, and she came, her seed mixed with the worms and the maggots that would start spreading the parasitic infestation through the doctor. He groaned, squirming under her, and she could tell that he was trying to fight it.

That was fine. She had plenty more where that came from, and by the time that she was done, she would have a drone doctor that was more than capable of infecting everyone else that came in contact with him.

The hive would spread.

The End
