#breeding trials

[crispysnakes]

A nice little litter of 10 dropped early Saturday morning, 5/16/26.

From a KRP Sunglow keywest arabesque x IMG sunglow motley.

Check out the lineage here.

I've been imagining being part of a breeding experiment and after all the medical checks, I get injected with a sedative that completely knocks me out. When I come to. I'm wearing an oxygen mask and completely naked, floating in a cylinder tank full of a translucent blue slime. Doctors stand all around me, staring up at me with their pens hovering over their notes.

The slime begins to move around me, and I feel it pressing into my ass and pussy, filling me completely in moments, squeezing into my womb, stretching me open. I try to close my legs, fighting the abrupt and aggressive force of the slime, and it pushes against the glass and forces my legs apart. I can see the doctors taking rigorous notes as the slime fucks me and I scream into my oxygen mask, trying not to cum in front of all these people. But then something solid pushes into my pussy, and then another, and I realizes it filling me with hard jelly eggs. I can't help but cum then, the little round eggs falling into my womb and making my stomach bulge and grow heavy until I'm shaking and cumming with every new egg.

The slime finishes filling me with eggs, and instead begins pouring its cum into me. When the eggs are packed tight with warm slick cum, the slime pulls put of me and releases me. A doctor flips a switch, and the slime drains from the tube, leaving me kneeling on the grate floor. Another switch, and a sickly sweet gas fills my mask and makes me absolutely dizzy and my clit begins throbbing, as if I didn't just finish being fucked senseless already. It must speed up the gestation period, because I feel the eggs split and small clusters of slime squirm out of my pussy. There must be at least fifty, and I can't stop cumming as they drip out of me one by one, shuddering with every orgasm as the doctors watch.

The last one slips through the grate, and I'm ble to catch my breath finally, just in time to notice something coming up through the grate and prodding at my holes as one of the doctors announces "begin the second trial."

I need more of your breeding trials content xD

It just makes me so wet reading it. Thanks for sharing it ^^

Hope this wasn't too out of the blue or rude !

Oh I'm happy to!!! Tbh I've been looking for an excuse to continue them.

Not every trial takes place in that tank. At one point, Im escorted down a hall and given a bath. Im still too exhausted to wash myself, so attendants gently wipe away various creatures cum and help me relax and eat. Im not given anything to cover myself, because what would be the point? And instead I'm left completely naked and led into what appears to be a large lush terrarium with some sort of thick trunked tree in the middle. I think perhaps this is to help me rest, surrounded my such beautiful plants and so comfortably warm under the heat lamps. Something to help ground me after the toll taken on my body perhaps. I'm given no instruction, except to explore this new area and promised that nothing inside is dangerous to touch. So I walk, tracing my fingers over the thick rubbery leaves, studying the massive flower buds that are bigger than me and must make for the most incredible flowers. The ground is soft, sinking under my steps and cradling my legs anytime I kneel to look at something closer. It feels like the whole place is begging me to lie down and rest.

I search the entire tank, which isn't small but ot still only takes a few minutes to see everything, and feel somewhat disappointed that none of those large buds have bloomed for me to see. I study one of them a little closer, touching the sturdy petals and trying to sniff for any sort of fragrance. There is one, something heavy and sweet, with a touch of something like sweat, and when i lean close to the buds, I see the scientists outside the glass begin writing in their notes.

Something creaks behind me, and I turn to see a new bud emerging from one of the thick vines that hangs off the tree. I walk to it as it opens, and I'm greeted with that overwhelmingly sweet smell, and I have to lean closer to inspect this strange new plant. I dont even notice the other vines descending around me, the ones leaking anhoney colored sap and pulsing softly. The flower shudders, and I recoil as pollen floods my senses. My clit begins throbbing immediately and I feel overwhelmingly dizzy, I find myself tanging in the vines, which are already smearing hot sap across my body as they writhe and try to find where they can force their way into my body. I manage to start to get away, or at least I think I do, before one of the vines suddenly forces itself into my pussy. I keep trying to drag myself away, but the bulb on its tip pushes into my womb, and I feel it open inside of me, rendering me unable to pull away as hot sap gushes into my womb.

The pollen is taking a real toll now, making me lose any interest in fighting. The more sap I feel pumping into me, the less I care about getting away. The vines caress my body, and i let out a moan as one pushes deep into my ass and pours out more sap. I let them drag me back, my cheek sliding on the soft ground, lifting my back half and pulling me into something I can't see. One more vine presses past my lips, squirming its way into my throat, pulsing gently and making me swallow that sweet intoxicating sap that makes my whole body burn and ache to cum.

I realize I'm being pulled into that massive flower I watched bloom, and that thin vines wriggle all along its petals, carressing and fucking me any way they can. I watch the scientists as the flower closes around me, plunging me now into a fragrant darkness, and the thin vines grope me, binding my wrists above my head, curling around my throat, pulling my hair, rubbing my clit, squirming inside me alongside the thicker sap filled vines. I cum easily enough, moaning weakly and nearly choking on sap. I think that will be it, but instead, more vines push their way into my pussy, one of them latches around my clit and begins pinching and massaging it. The more i struggle, the harder they fuck me, milking orgasm after orgasm, apparently emboldened everytime they make me cum. The sap changes, turning almost salty, tasting more and more like human cum, and its effect grows stronger until I cum from its influence alone. When I no longer need the vines to make me cum, the ones iny pussy withdraw, replaced by a star shaped smaller flower like appendage. It latches itself between my legs, sucking out my cum, a thin tendril burrying deep in my pussy to coax my cum onto what I can only describe as a mouth. The vines in my ass and mout continue filling me, pumping me with that cum like sap that makes it impossible for me to stop orgasming, even as my consciousness fades.

Hours later, I wake up to the vines finally slipping out of me. My belly bulges with sap, and a few vines curl around my midsection and squeeze me to send it pouring out of my holes. The flower opens, and i tumble forward into a thick puddle of the sap, along with a few other test subject who look just as exhausted as I am. I still cant move, and the residual sap still makes my pussy clench as I cum a few more times before I finally go limp on the ground, and a couple scientists carry me put of the tank to study my body im the aftermath of the plant's merciless use of my holes

More breeding trials content? Please? 🥺🥺🥺

After some rest, I wake up on my stomach, my arms and legs straddling a sort of bench that keeps my hips elevated. Im unable to move, but I feel something being eased into my pussy while something else is positioned against my clit.

"Good, you're awake," one of the doctors says. She lays her hand on the back of my head, "the next creature is too dangerous to let breed you directly, but it needs its eggs fertilized in a warm environment," she strokes my hair, "and you're nice and empty." She pets my cheek. "We've given you a paralyzing serum so you cant hurt yourself, but you'll still feel everything, and I'll personally supervise the experiment, just us two." She grips my chin, "you can trust me to take good care of you."

She snaps her fingers, and whatever is being pushed into me stops. "I can take it from here." I listen to the other doctors leave, and then I hear a switch flick. After a moment, th device against my clit begind to vibrate softly. "You're such a slut. I mean, agreeing to this is proof enough, but one of the other doctors told me how you came all over her cock." I feel her hand grab my ass, "I want a turn filling you up with cum too. I know you dont mind, you're here after all." She walks forward and fastens a mask over my mouth and nose, "lets get you nice and pliant for those eggs," she whispers. A gas pours into my lungs, making me dizzy and making my clit throb. I try to pull against my restraints to spready legs more. "Aw, poor thing, you want a nice cock inside you, dont you?" I nod desperately. "Good girl. You take all those eggs, and I'll take this mask off and you can show me how much you love my cock in your throat. You'd love that, wouldnt you?" I nod again. "Good. Lets get started." I hear another switch, and something presses against my pussy. I groan as the first egg pushes slowly into me, sinking deeper until it meets my cervix, but it wont move deeper. I whine, trying to grind against the vibrator.

"Oh, is it too big?" She steps behind me, and I feel her adjust the vibrator, "I really dont want you to get to cum, I think its more fun that way, but I guess you have to if we're ever going to get you relaxed enough for these." Another egg is already sliding into me, and the building pressure makes me gasp. I still cant move, even as she turns up the vibrations and I want to pull away from the intense buzz. I cum easily, and as my body siezes and goes limp, the egg slips inside. I immediately feel its weight, and the next is rapidly sinking into me too, while another presses against my hole. She leaves the vibrator on its high setting, and stands in front of me again, I can see her bulge through her pants, and she slowly unzips them so I can see it straining against her underwear.

"You want my cock so bad, dont you dear?" I groan as more eggs spill into me, "oh you're such a pitiful little slut, I'm so glad you found us." The machine shuts off as the last egg forces it's way into me, and she gently undoes my restraints and turns me onto my back. Above me, I see two clear tanks, absolutely filled with something thick and white. "Its an interesting creature, fertilizing its eggs inside a host to maintain a comstant temperature and keep them safe. Once they're fertilized, the host's body naturally pushes the eggs out." She removes the tube that previously delivered the eggs into my womb, and replacesnit with a new machine after thoroughly coating it in lube and olacing the tip just inside my hole. "It takes a lot of cum to fertilize the eggs through," she gestures to the tanks, "its okay of it doesn't all fit inside you, but we need you stuffed to the brim with cum for at least an hour. So I'm going to make sure you're nice and full, I'm sure you'll love that, wont you?" I nod absent mindedly. "Good girl. And, while you take all that cum, I'm going to fill up you're throat with mine." She turns on the machine, and I feel it begin to thrust into me nice and slow, working me closer and closer to orgasm.

She moves back to my head, and carefully adjusts me so my head hangs off the edge of the bench. Her hands shake as pulls out her cock, and I can see it twitch as she strokes it. I open my mouth, practically on instinct now. "Good girl," she says breathlessly, "good little slut. Pretty cock whore, you just need something to fuck your holes at all times, dont you?" She doesnt wait for an answer, just pulls off the mask and forces her cock into my mouth. She groans, and i feel her thumb press against my throat, feeling her own cock sink in and out of me. She holds the mask over her own face, breathing the aphrodisiac in deep, before fucking me harder, desperately, practically feral in her need to cum in my throat. Despite her roughness, she praises me, telling me what a nice soft mouth I have, how I'm just made to take girl cock, I look so good with cum dripping out of my holes, and she loves watching me be bred by all the creatures, seeing my pleasure, and knowing she helps cause it.

I choke when she cums, bit she doesn't pull out, "swallow it. Every drop, whore. You dont want to leave any evidence and get me in trouble, do you?" She grits her teeth as she thrusts and shoots more cum down my throat, "Other girls cant take advantage of you like this if I get caught, and you want us to keep using you, dont you?" I nod, too dazed to disagree, and in far too much pleasure to want to disagree. "Thats a good girl. Taking all this cum, just like she's supposed to," she leans over me, and her fingers touch my clit, making my body spasm, "so sensitive!" She laughs, and slowly pulls out of me, wiping my mouth clean for me. "Lets keep it that way." She readjusts the vibrator against my clit amd turns it up, and I scream as I cum, and she just sits and watches, making occasional comments that make my pussy clench as she forces me to cum over and over uncontrollably.

When the tanks are empty, the excess cum drips in streams down my legs and onto the floor. "Wow," she laughs, "you took it all already, good job." She removes the machine, and quickly forces in a thick plug before too much of it gushes back out. "Now just relax," she turns the vibrator up, "and I'll be back in an hour to help you get those eggs out."

She leaves me, twitching pathetically with every orgasm. A few doctors step in to check on me, but none of them turn off the vibrator or speak to me, only admire the bulges in my stomach and the thick pools of cum on the floor. A couple of them touch me, running theor hands over my breast or stomach. One of them gives the plug a teasing pull that makes me shudder, and then she laughs amd leaves me again.

When the supervising doctor returns, she adjusts the bench so I'm more upright, but still restrained with my legs spread. "The others want to fuck you so bad," she whispers, "no one would even stop us, least of all you." She runs her hands over my body, "you're just a breeding whore, you exist to be filled amd fucked and used, amd you love it, dont you?" I nod, weak and barely conscious anymore. "I thought so. Lets get you emptied and cleaned up for the next thing to fuck you, shall we?"

She pulls out the plug, and I'm grateful for the restraints keeping me upright as cum gushes out of me and I let out a long moan. The eggs come next, just as thick amd difficult as they were going in, but she uses her fingers to spread me open and coax them out, making me cum between each one to help them ease out, whispering praise as she gropes me and tells me how excited she is to fuck my holes again soon, until the last egg drops into the bin she positioned below me.

"Good girl," she kisses my cheek, "someones going to come clean you up, and you'll get to sleep in a nice bed for the night, but in the morning, we have all kinds of fun new experiments for you." She laughs as she leaves me, and sure enough a nurse comes in to help me to the showers and bathe me, though she undeniably takes extra liberties pushing her fingers into my pussy to help clean put the excess cum. Im taken to a soft bed and given food, and the second I lay down, I fall into a deep sleep, all in preparation for another long day tomorrow.

[feral-and-or-horny]

I'm interested!

After the last trial with the plant creature, I'm inspected by a small team of doctors, who had me laid down with my feet in sirrups and my legs spread, the cold air makes my pussy clench and I can't stop whimpering. They only discuss the trial, both my experience and those of the other subjects, and occasionally one of them will push their gloved fingers into me and then pull them out to show their colleagues the mix of cum and sap.

I learn that the plant feeds on the cum of any creatures it can capture, and alters the chemical makeup of it's sap to suit its victims and uniquely make them cum. Its apparently one of their favorite subjects to experiment with, and they jokingly talk about hopping into the terrarium after a long stressful day.

One of the doctors, whom I assume is in charge, is the only one who ever looks at me in the eye. When she pushes her fingers into me, theres a slow deliberate pace to it, and she curls her fingers inside me before pulling them out. "You have to wonder about the people who signed up for these trials," she says, "volunteering for a series of sex experiments with strange creatures and asking for no details? What kind of person agrees to something like that?" The other doctors snicker, and a couple of them glance at my twitching pussy. The head doctor dismisses them, saying she wants to have a private conversation with me. She gets a cool wet cloth and begins carefully wiping the sap and cum off of me, being so gentle I immediately relax. "Why dont I turn these cameras off," she smiles, "then you can have some real privacy, no one looking at you but me, would that be alright?" I nod eagerly, just glad for some vague semblance of privacy for the first time since I came here.

"You're doing very well," she tells me, wiping away the sap on my breasts, making my nipples stiffen as the cold air hits them again, "not everyone could handle these experiments," she stands between my legs, wiping down my arms and smiling at me, "it takes a particularly disgusting whore to do something like this." I feel restraints tighten on my wrists, "you barely fight these things when they're breeding you, and you let all of us watch you?" She sets a row of vials on the table beside my head, "what a good little slut you must be. If you like all those monsters cocks filling you up, I'm sure you wont mind mine? I have a few experiments of my own I'd like to try." She holds up a vial, and I recognize the now milky sap inside it. She dabs some on her finger and rubs it into my clit. I immediately convulse, cumming violently and practically trying to thrash off the table.

"What a good girl," the doctor coos, and I hear the sound of a belt being undone, then the head of her cock presses against my hole, "lets see if you can make me cum from your orgasms alone. If you cant, I'll just get more sap and we'll try again later, how's that sound?" I start to protest, but she pours a vial in my mouth and then clamps my mouth and nose shut, forcing me to swallow it all. The orgasms come in violent waves, one right after another, making me clench hard around the doctors cock now buried in my pussy. She groans through my first several waves, her hands exploring my body as she calls me her good little whore. When my orgasms slow down, she forces me to drink the next vial. It goes on like that for several minutes, but she hasnt cum yet and only one vial is left. Her veneer of sweetness is gone as she takes the last vial and whispers, "I'm not letting you leave til I've bred your pussy enough for every momster to smell it, little whore." She drinks the last vial, and pulls my hips flush with hers as she cums in me over and over. She leans down, kissing me and forcing some residual sap down my throat to make me cum too. Her nails dig into my skin as her cum gushes into me, filling me nice and deep, helped along by her shaky but hard thrusts. When she pulls out of me, I hear her cum slosh out and spill on the floor as my pussy clenches around empty air. She watches me, and I hear her laugh softly. "You'll make a good cum dump for me," she begins cleaning me up in earnest this time, "I'll use your mouth next time, but until then," she undoes my restraints, "its time for some more monsters to use those pretty holes of yours."

[feral-and-or-horny]

more breeding trials? 👀👀

The next trial has me strapped onto a breeding mount. Ive stopped bothering with questions by now, knowing I'll only be answered with laughter or teasing, but I still try to eavesdrop. I learn little, other than that they expect I'll be able to hand a couple more experiments today after this one. I decide to simply relax, knowing better than to panic at the pack of information. Some of the creatures seem to enjoy when I panic, with how it makes my body tense and tighten around them and gives them an excuss to force me roughly against the ground.

"So thats the one Im using?" I assume the woman I hear is another doctor, one who's going to take advantage of the lack of witnesses who care.

"It is," another one answers her, "she's handled plenty before, so Im sure she'll take you without too much trouble." Two fingers press into my pussy, pushing deep until her fingertips brush my cervix.

"It's not deep enough," the first woman sighs.

"She can handle some force. She's done it often enough now, we stretch her to her limit almost daily." The other doctor sounds proud as she reports my progress, "besides, wont such a tight fit feel good?"

The first woman curls her fingers inside me, not answering as she slowly works her fingers inside me. "Alright, I'll use it." She wipes her fingers on my thigh, and I feel her body weight settle against my back, warm and soft and heavy. When I see the hooved legs bracing on either side of me, I realize she's not another doctor, and the massive cock brushing against my ass is all the more proof.

The doctor who was talking to her walks around me, and i catch the word "centaur" on her clip board. I think, briefly, that being used by a more humanoid creature might be a good thing, perhaps she'll be gentle, she was comcerned that she was too big for me after all, so maybe–

My mind goes blank as she bottoms out in me on the first thrust, my vision going white and my breath leaving my lungs for a long second. When I can think again, I know the centaur woman wont be gentle. The doctors may have seen me as nothing but a breeding whore, but at least they recognized some previous humanity in me, thats where their delight in using me came from. But the centaur woman? I was a thing to empty her cock into, as feeling as the breeding mount I'd been strapped to.

Her hand gripped the back of my head for leverage, pressing me into the thick material of the mount as she fucked me, her cock struggling fo bulge through my stomach where it rested on the mount. Each thrust came with brutal force, without a bit of hesitation or mercy, her only interest was cumming. When she came, it was overwhelming, torrents of hot cum filling my womb and leaving me choking on the shock.

"Im not done, can I use it's other hole?" The centaur woman asked already rubbing her cock against my ass.

"Thats fine," one of the doctors answered, "just give us a second to prepare her." A few of them walked behind me, and fingers covered in cold lube began stretching my hole. I tried to beg, to tell them I couldn't take it, but I was ignored. Slowly, I felt her cock begin to push slowly into my ass, still accompanied by fingers helping to stretch me open.

The doctors finally leave her, and the centaur woman grips my shoulders to fuck me properly herself. I keep begging, telling her and to doctors that I can take it, she's too big, her cock is going to break me, but the longer I beg, the more excited the doctors look.

When she cums this time, i think i might pass out. I can feel it pooling deep inside me, overflowing my tight body, and gushing out when the centaur woman pulled out, giving my ass an almost affectionate pat as she left.

"We'll just keep her strapped in, there's no point in getting her down when something else is just gonna fuck her again," one of the doctors says, "clean her up for the next trial."

[feral-and-or-horny]

Any more breeding trials thoughts at the moment? They're always so good😊

Im not given any real rest after the centaur, only cleaned up for the next monster. The monster they bring in is a reptilian woman, and she is less passive towards me than the centaur, and she delights in holding my head up by my hair and rubbing her twin cocks against my cheek as the doctors talk to her. When she positions herself over me, she drags her serpentine tongue up my spine before forcing her cocks intoy pussy. I gasp at the sudden fullness, and she forces my head back and takes advantage of my open mouth to slip her tongue down my throat, fucking me with it as deftly and eagerly as if it were her cock. She drools over my open mouth as she fucks me, her tongue writhing in my throat, slithering as deep as she can go before she leans back and licks up the mess around my mouth. I can barely keep up with the overwhelming sensations of her cocks twitching inside me as her tongue explores my mouth over and over, utterly ignoring my choking and pleas to slow down.

She jerks my head up, forcing me to look at the small crowd of doctors watching us as she cums deep inside me, laughing as I cum too, shaking hard beneath her and clenching around her cocks.

"You can go again if you want," one of the doctors tells her, and she launches into another round without hesitation. She grips my throat hard with one hand, as the other digs its claws into my thighs and she continues throat fucking me with her tongue. When one of her cocks slips put of my pussy and into my ass instead, she just laughs and fucks me harder, squeezing my throat until I cum and coax another orgasm from her cocks again.

When she finally pulls out of me, she pauses and I feel her tongue lick and suck her cum out of me, sending me into one last shaling orgasm before Im left alone again, and prepared for one last trial.

[feral-and-or-horny]

hi i keep thinking abt ur breeding trials and being one of the scientists. maybe next time we drop the pretense and just strap you to a table. 'the next trial is to see how fast you can make me cum.'

Okay but being strapped down by a lone doctor, only to hear what she's using me for and try in vain to call for help, only to be silenced as her cock slides into my throat. When she cums, I stupidly think that'll be it.

"I think we can do better," she says, and I gasp as her cock sinks into my pussy. My poor body is conditioned beyond rational thought, and I cum so easily on her cock. "I knew you'd have fun, slut," she laughs as I whimper through my orgasm, "let's find out which hole is best for cumming in."

She cums in my pussy with a long groan, and I shiver as I feel it filling me. She doesn't wait long, and I feel her cock in my ass next, stretching me slowly, smearing my cum still coating her cock inside me. She grunts her praise for my holes as she fucks me, telling me I'm so soft and warm, I feel so good around her cock, I'm made to be a whore, aren't I?

When she finishes, she doesn't pull out. Instead, she lays over me, idly continuing to fuck my ass as she holds her phone in front of my face to show me the video she took of her cock filling my pussy then my ass, making me watch it as she keeps fucking me, panting in my ear and flooding my ass with her cum all over again.
