Abandoning whatever caution you may have had before, you bring the collar to your neck, slowly wrapping it around your nape until the two ends of its buckle are right next to each other. Well, you’ve come this far already, no turning back now. You let the two electro-magnets snap closed together with a metallic ca-thunk, and as soon as the buckle is well and shut, a small red light turns on. Shortly after the crimson beacon starts blinking in the corner of your eye, the collar starts to emit a soft metallic hum. You feel your thoughts growing hazy as that gentle noise floods your mind.

It’s as if your own body is becoming heavier under the weight of the sound, almost to the point where you consider sitting down before a static-filled voice coming from the collar breaks your focus.

“Well, well,” is the first thing you hear; the voice is poised, and most definitely feminine, “Looks like someone other than me finally found my collar.”

You try to respond but nothing comes out. All you feel is that static hum compelling you to stand there and wait for that voice again.

“Just be a dear and stay there for a moment,” the voice calls out from the collar again, “I’ll be there soon to get my property back.”

That... that sounds exactly like what you want to do. Once again that steady humming makes your body feel heavy and you think you should take a seat some- no, no... that won’t do; you need to lower yourself, and wait for whoever’s voice that was to come get you.

You quickly fall to the ground on all fours; yeah, that feels good.

You wait there for a while, not feeling any need to move from where you are. Resting here on your hands and knees feels perfect. A few passersby give you strange looks, but you can’t really bring yourself to care; all you can really do is wait here on all fours, feeling happy more than anything else.

Only a little more time passes before you hear the same voice you heard from the collar, though this time it’s free of the static from earlier.

“Ah, there you are,” the voice says, causing you to turn your gaze towards what looks to be a human woman. She’s got a very wide set of hips that only draw attention to an even more impressive derriere... along with the enormous bulge opposite that. You move your gaze up past her slim waist and comparatively large breasts, double-Ds at the least, to a jaw-droppingly feminine face: pouty lips and green eyes. Her long, black hair is being kept in a ponytail, keeping it away from her fair skin and the lab coat she’s wearing. All you can feel looking at her is an overwhelming want, your whole body eagerly awaiting whatever it is she has to say.

“Mmmm,” she coos, letting her eyes run up and down your form, “What do we have here?”

You try to speak, but nothing’s coming out of your mouth, your lips refusing to move. No, silence will do for now.

The woman suddenly reaches a hand down toward your head followed by a sense of growing eagerness on your part. You close your eyes in anticipation, awaiting her touch, no longer worrying about that pesky collar; your talented tail even start to wag without you noticing.

Then your cat-like ears are greeted by the gentle clink of metal on metal.

You open your eyes to reveal your mystery woman straightening herself, holding a leash in her hand as you come to the realization that you’ve just been thoroughly collared and tethered; but that’s not really a bad thing is it?

“Unfortunately for you,” the woman says with more than a bit of condescension in her voice, “Before I can take the collar off, I’m going to have to bring you back to my lab and you’re going to have to participate in a few... experiments, but by the looks of things you don’t mind that. Do you?”

No! Of course you don’t mind. You don’t think you could find a way to mind with such a lovely lady holding your leash, and you shake your head to tell her such.

The woman smiles before reaching a hand down to give you a pat on the head, causing a wave of ecstasy to shoot down your spine when her hand makes contact, “Good, then come along, pet.”

You are led around by this wonderful woman around the wabeship that is Uveto station, crawling along the floor until you reach what must be the scientist’s lab.

Finally walking inside behind the scientist, your eyes are greeted by a wealth of scientific equipment: blinking lights and computers, and bundles of wires lining the walls of the small lab. Though, beyond that most of the equipment seems to be related to audio: radios and speakers, various instruments lined up next to microphones, even a row of wine glasses and spoons placed carefully near a group of transceivers.

“Welcome,” the lady-scientist exclaims, extending an arm, “To Accu-Pitch labs, or my lab, if you want to get specific.” She turns around to look down at you, “What you’re wearing there is one of my inventions. I call it the Sub-Tuner. It releases a series of harmonic frequencies that alter brain patterns, making the wearer more submissive and... suggestible, but I’m sure you’ve already noticed that.”

Well, that does explain a lot, but you can’t work up the drive to question anything that’s going on right now. All you want to do is await more orders, so you content yourself to sitting there on your hands and knees, looking up at the black-haired woman with a smile on your face , nimble tails swaying gently.

She grins back down at you before continuing, “The specific collar you’re wearing is one of my latest prototypes, and it has a few new features which you’re going to help me test; isn’t that right?”

Of course! That’s what you’re here for. You turn to gaze up at the lady-scientist, giving her a nod and a big grin.

“Good,” she begins, “I assure you I will have that collar off you once all my tests are complete, but in the meantime, I suppose we should get started.” The wide-hipped woman takes a few strides closer to you, “I’m Belle, by the way, and you... you’re my little pet, for now.”

Belle keeps a tight grip on your leash, tracing a circle around you and stroking her chin. “Hmmm,” she deliberates, “No, these clothes you’re wearing won’t do at all. They’ll obstruct my readings, so I guess we’ll have to get them off won’t we?”

You can feel your mind go blank at that question, unable to feel anything but excitement at that proposition. Quickly pulling yourself together, you give Belle a nod, resulting in a confident smirk from the scientist.

“Alright then, girl, sit up,” she commands.

Without a thought you heed her order, sitting yourself up on your knees, keeping your arms curled up like a puppy’s and looking up at your master with growing eagerness. Belle slips down onto her knees, getting herself close enough to you that you can feel the heat radiating off her immense bulge. She grabs at your equipment and pulls it away until all your flesh is laid bare before her, leaving the lady scientist with a wide grin on her face, “That’s more like it.”

Your new master gazes at your naked form for a long moment before taking up a position behind you, and you can practically feel her eyes scan your nicely-rounded, heart-shaped tush. You don’t turn to face her, though, because a good pet waits for their orders. All you can do is sit there and tremble with anticipation as Belle kneels down behind you, “I suppose you should be punished for taking things that don’t belong to you.”

With that said, a palm caresses one of your lower cheeks, causing you to gasp at the sudden sensation of your master’s warm flesh on yours, “Yes, I think you’ve been a very bad girl, taking my collar without my permission.”

Without a single warning you feel a second hand smack against your bottom with a great slap, making you cry out as your assflesh is reddened by Belle’s punishing strike.
“Bad girl,” she chides before delivering another slap to your more neglected cheek, sending a jolt of pleasure shooting through your spine, “That’s a very bad girl.”

You can’t help but feel some sort of bliss when she does that, her words and strenuous smacks culminating in some burning desire deep within you. Yes, it feels so good to be put in your place. You’re so turned on you barely notice your needy quim leaking fem-lube onto the ground beneath you. Your master notices, though.

“What’s this?” Belle questions, reaching a hand down to trace a finger across your lube-leaking slit, “Are you getting off on this, you dirty girl?”

She gives your ass another rough slap before sending a pair of her fingers into your sodden cunt, spreading your nether lips and drawing a little whimper from you in the process.

The sensations of pleasure and pain leave your body tingling with bliss, with Belle’s fingers thoroughly filling your pussy, drawing in and out of your slick hole until you’re left moaning and whimpering, all the while her free hand delivers ass-reddening spanks to your butt.

“Does the bad, dirty girl like that?” the wide-hipped woman asks, giving your lower-cheeks another firm slap, making you moan.

You’re only able to give the lady scientist a nod and a pitiful whimper, the need to cum overtaking your mind as pleasure burns in your loins, but you can’t cum without your master’s permission, and she knows that. Turning back to face Belle, you give her a good view of your needy gaze and a lustful whine.

“What’s wrong, girl?” she asks, “Can’t cum?”

You give her another nod, barely able to hold back the wave of endorphins trying to flood your mind.
“Good,” she says plainly, removing her fingers from your quivering cunt, leaving you leaking girlcum onto the floor with a whimper, “That means the submission protocols are working better than I could have expected.”

Belle stands herself up again, keeping a tight grip on your leash as she walks around in front of you again. Before she says anything else, the human woman bends down and gives you a scritch between your pointed ears, “Nice job with that test, girl.”

You did do a good job with that, didn’t you? Though, a “good job” doesn’t exactly give your slobbering pussy or your sorely-spanked bottom any relief.
“But,” Belle begins, giving her finger a little waggle and walking towards the door of her lab in a way that makes her booty quake in the most perfect way, “Why don’t we see just how far we can push those protocols?”

You’re not quite sure what that means, but your tails wag eagerly in anticipation for what’s to come.

Belle turns around to look over her shoulder at you, giving you a wide grin, “How about we go for a walk, girl? Really put the Sub-Tuner to the test, how does that sound?”

A WALK?! As if you could say no! You quickly nod your head without any hint of hesitation, ready to heed any command the wide-hipped woman before you has to offer.

Smiling at your compliance, Belle gives your leash a tug and starts to walk out of the lab, “Well then let’s get going, girl. We haven’t a moment of time to lose on this precious research.”

Belle leads you around Uveto station for quite some time, testing the abilities of her collar in all different ways. Sometimes she encourages you to go receive all manners of pets and praise from passersby, only to later chide you for talking to strangers, though, you can’t find yourself upset about it. Your master knows best, after all. Other times she instructs you to provide passing huskar, toves, and other aliens with a show, making you wiggle your butt in the air for them. Some of them respond to your teasing movements with slaps and gropes, but you don’t mind, because being a good little pet is all the reward you need.

At one point, you’re walking through the pathways of the re-purposed wabeship when you come across your own white-haired ausar slut: Anno. She approaches you and Belle with a wide grin on her face, seeing you in a collar obviously being something she enjoys.

“Hey there, boss,” the ausar beauty calls out, causing you to look up at her, “Hope you’re not having too much fun without me out here.” Tossing you a quick wink, Anno turns her attention to Belle, who is just as interested in the snowy-haired pup as she is in you.

“Oh, you must be a friend of my pet then?” she asks, extending a hand and introduces herself as “Dr. Belle Baslocvicz” before she continues. “Your ‘boss’ has been oh-so kind enough to help me with a few experiments here.” Running her eyes up and down Anno’s curvy form for a moment, she continues her introductions, “And I must say, I wouldn’t mind getting your help for a few experiments.”

Anno giggles and extends her hand to shake Belle’s, “Well, it looks like Genny is having fun, so I may have to take you up on that offer.”

The two say their goodbyes, leaving you and Belle relatively alone in the wide open dome of Uveto station.
You feel a small pang of shame at the fact that you were caught in the act like that. Maybe that’ll teach you to not fiddle with weird collars you find on space stations.

It isn’t long before your master decides it’s about time to take a break, propping herself up against a nearby wall and giving you an order of “Sit, girl.” She waits there for a moment, scanning the foot traffic around her before calling you over to her.

Quickly heeding her command, you crawl your way over to Belle on your hand and knees until you’re right in front of her, looking up at her with eager eyes. Without any ritual or hesitation, the lady scientist quickly unbuckles her pants, and lets her package dangle free before you.

Your eyes bulge and your tongue lolls at what you’re presented with: two knotted human cocks, each easily measuring a foot in length, with a nice, plump pair of balls to match, and it all looks so delicious. All you can think of is having both of those wonderful dongs between your lips, shooting their hot load down your throat, but you can only sit here and wait for your master’s next command, like a good pet.

“Like what you see, girl?” Belle asks with a smile, reaching a hand down to cup your cheek while simultaneously yanking your leash to pull your face into her crotch.

The smell is heavenly, so earthy and musky, and paired with the heat radiating off her package and onto your cheeks, all you can do is look up at her and pant in answer.

“Well, come on then,” the dual-dicked woman says, “Fetch.”
That’s all the invitation you need. You dart for her lower shaft almost immediately, taking her cockhead into your mouth and starting to slide your lips down her shaft, barely giving yourself any time to breath. Belle places a hand on your head, letting a pleasured, shuddering breath escape her lips as the molten cockflesh of her upper dong carresses your cheek. Speaking of her other cock, it seems a little neglected, desperately and enviously leaking pre onto your face. That won’t do at all; you need to make sure your master feels as good as possible. Far beyond being able to have second thoughts at this point, you reach a hand up and take hold of Belle’s other cock, gently stroking it as you start bob your head up and down her lower, equally turgid and lengthy rod.

“Ah, yes!” The lady scientist moans, giving your ears a scritch, “Good girl, keep going, just like that.”

You can almost feel the woman’s grip on your leash tighten as you start to move your tongue along the cock lodged firmly in your mouth, tracing all along her shaft and wetting her cockflesh with your saliva. Even though you can’t see it, you can definitely sense a crowd gathering behind you to watch this little spectacle unfold, but you can’t focus on that right now, because all that matters is making your master cum.

Redoubling your efforts, you start to move your mouth and hand faster, striving to bring Belle to orgasm. Your hard work quickly pays off, because soon after you hear a long, lewd groan force its way past the human woman’s pouty lips, her grip on your head tightening. You can already feel her cocks spasm in your mouth and dexterous grip.

You’re rewarded with a big, salty load down your throat, creamy spunk flowing down your gullet as your master rides out her climax, swelling your stomach until you’re feeling quite full and looking positively pregnant. Meanwhile, her other dong discharges all over your face, hair, and hand, leaving you thoroughly covered in hot white terran cum.

Pulling yourself off Belle’s twin cocks as she cums down from her peak, you look up at her expectantly, your face glazed with her seed and your tummy filled with her bountiful load.

“Good girl,” she manages to coo between lengthy breaths, her large chest heaving.

You smile at her words, and why wouldn’t you? You did such a good job making your master cum like that.

“Well, looks like those ‘master first’ subroutines I programmed are working perfectly now, unlike the last time I tried this,” Belle says, pulling her pants back up and taking a good look at the now dispersing crowd, “Come then, girl, there’s just one last thing I need to test before we can get that collar off you.”

Belle walks you back to her lab, keeping a firm grip on your leash in an attempt to avoid any further distractions, although your naked form and cum-covered face draw more than a few lustful looks on the way back. Your master keeps you in line though, all the way back to her scientific workspace.

Once you’re well within the relative privacy of Belle’s lab, the lady scientist walks over to a nearby bench and picks up a small remote, still leading you by your leash.

“This,” she begins, holding up the remote for you to see, “Is the newest addition to the Sub-Tuner, and I’ve still yet to test it. So, you’re going to be the very first person to try out the new ‘heat’ functions.” The green-eyed woman goes to press a small button on the remote before continuing, keeping her eyes fixed on you, “You may notice some... unpleasant sensations.”

Almost immediately after that little switch is flicked, you can feel your cunny slobbering with a want to be filled. Heat flushes through your body, a sign of your hunger that can only be sated by one thing: sex. There’s no doubt about it: you’re in heat, and you need to breed.

You look up to your master and whine, whimpering to let her know of your sexual distress. She responds with a smirk before speaking up again, “Hmm, looks like it’s working.”

Your master circles around behind you, getting a good look at your wet, needy pussy as she kneels down, getting her hands all over your girly hips. Shortly after, you feel a finger run along your nether-lips, gathering up beads of translucent girl-cum as it makes its way towards your taint.

“My, my,” Belle breaths lustfully, “Looks like the heat harmonics might have been tuned a little too high, judging by how wet you are. What do you say, girl, want me to fix that problem for you?”

You manage to look over your shoulder at the human woman and give her a whimper and a nod, with your desire to cum only having grown since your earlier escapades with the lady scientist.

Turning back around, you need only wait a moment before your feel one of Belle’s cockheads press against your juice-drooling slit, and another against your welcoming asshole. The sudden pressure on both of your sodden holes makes you whimper with pleasure and pain. Before you can try to relax, your master thrusts her hips forwards, slipping her twin dongs into both of your holes. You cry out with pleasure as you’re penetrated by both of Belle’s cocks at once, spreading your pucker wide open and leaving your pussy wonderfully agape. Barely giving you any time to recover from her dual-dicks, the lady scientist behind you starts to shove more and more terran cock into you.

It isn’t long before your master’s ever-expansive hips start to move, fucking you like the bitch in heat you are, her knots spreading your supple entrances with each thrust. The feeling of being bred like this, of having your hungers sated, it all feels so good. You moan as loud as you can with each thrust of Belle’s foot-long cocks, crying out as your inner walls hug at her shafts, eagerly accepting her turgid dicks into your waiting holes.

With Belle’s twin cocks punishing your pussy and butthole alike, you can already feel an overwhelming desire to cum swelling inside your heat-addled mind, but you can’t cum without your master’s permission.

In a desperate attempt to reach climax, you turn your head to look back at the human woman fucking you, giving her a whine to let her know of your desires.

“What’s wrong, g-girl?” Belle manages to blurt out, sounding like she’s on the verge of orgasm herself, “Want to cum? Well, c-come on, girl, CUM!”

Yes! Yes! You have to cum now, your master told you too! Your cock-hungry cunt begins to spasm around Belle’s pussy-filling phallus while your loose pucker does the same. You can hear your master groan with bliss as your holes tighten around her dual-dongs, still slamming her wide hips against yours. With climax overtaking your mind, you’re hardly able to notice your master’s own orgasm beginning.

Girl-cum spills out around one of Belle’s turgid terran rods as it spasms inside your cunt, her upper cock doing the same, already dispensing their white, molten loads into both of your holes. With not a moment to lose, the multi-cocked human slams her hips forward, driving her knots into your holes. You cry out as your pussy and welcoming butthole are spread even wider by the balls of cockflesh, stretching your orifices until they finally pop in, leaving you in ecstasy. You whimper as you’re pumped full of your master’s seed for the second time today, feeling her hot cum distend your pudgy middle until you’re feeling and looking full all over again. The lady scientist’s orgasm persists for quite some time, fully emptying her large pair of balls into you until the pressure is so great cum can only dribble out of your sodden, well-used holes. You did a good job making your master cum like that.

You’re left panting under the weight of your post-orgasmic euphoria, with Belle’s chest heaving with every breath she takes. Looking back at your master for some sign of approval, she gives you a slap on your cushy ass along with a tired, out-of-breath “Good girl.”

What a good pet you are.

After giving her knots some time to deflate, your master pulls her foot-long, twin dongs out of your cum-filled, gaping entrances, leaving you there to shudder as you’re emptied. Belle quickly picks herself up and pulls herself together before returning to the matter at hand again: you.

“Before I let you go,” Belle begins, reaching over to a nearby lab bench and grabbing a small, black, rectangular box, “There’s just one last thing I need to give you.”

With that said, the Lady scientist walk around behind you, taking up a position just behind your nicely-rounded, heart-shaped derriere. You’re unable to control your excitement, expecting another treat from your master, nimble tails wagging uncontrollably.

Then you feel plastic press against your skin followed by a light tingling sensation from what you can only assume to be the strange device only moments before Belle pulls herself back with a quiet “There we go.”

Turning your head to try and get a look at what just happened, you’re able to make out what seems to be a barcode on your rump; it’s black, sleek, and more than a bit demeaning.

You gaze back up at your master with a confused look on your face, expecting some sort of explanation from the woman, though, she doesn’t have to answer to her pet.

The woman returns your curious mien with a smirk, “I keep very detailed files on all of my test subjects, and I need one for you, especially.”

Belle goes to grab your leash, giving you and order of “Up, girl” as she pulls your tether taut, and quick to follow orders, you stand up.

“Everything’s working better than I could have hoped,” your master exclaims, reaching to unhook her leash from your collar, “Which means this little endeavor has yielded more potential than I would have ever believed, and I couldn’t have done it without you, good girl.” She scratches your pointed ears, giving you the most profound sense of fulfillment you’ve felt in a while.

Then Belle extends a single finger, and turns your collar off. All your pet-like feelings fade in an instant, dying down until you realize what you’ve been doing for the past few hours, though, you can’t find yourself upset about any off it, as if a hint of the leather ring’s subbiness has rubbed off on you. You also couldn’t deny that all that sex was mind-blowing... even if you wanted to.

At this point you can only give your former-master a blank stare, finding yourself at a loss for words. Belle knows just what to say though: “Hmm, why don’t you keep that collar; no doubt I’ll be working on a new prototype for quite some time. I must say, you’re one of the best subjects I’ve ever had, and it would just be wonderful if you ever felt like running some more tests with me. Don’t worry about that thing turning on, by the way. It’s got a proximity limiter installed, and can’t be activated unless you’re well and deep inside my lab. Well, I suppose you should get dressed and be on your way.”

Yeah, that sounds like a good idea right about now.
