They bring in a virile and strong, territorial tiger male for you to spar with. But this time, it's not a partially transformed person half human or anthro like you or the others.. This one seems like they're on all fours, with a full beastly feral quadruped frame. Their penis is long, thick, red and barbed and a gifted 12 inches long. Their body is lithe, agile, and yet still smaller than those bear sized tigers, but still like 1.5x the size of a big sized dog like a german shepherd, but not quite a hulking bear sized beast. They seem on the youthful transformation side as they eye you. Their balls also hung and producing powerful hormones as you sprout their crimson barbed cock drips as they turn their snout and curl it into a snarl at you. You instinctually return a growl as you return the same, you're still not fully transformed, but armed with feline claw, and fang, you feel good.. Even if your lower half might still be a area of weakness. your front seems strong enough to stake a fight.
And the tiger lets out a deep threatening growl as he steps towards you in animal stance. He leans forward, curling his mouth with teeth bared and his lips extended to smell you as his claws stretch and extend, growing outwards and pinning you to the floor. You both growl and scuffle and fight, you're able to push him off, but not before his throbbing penis spreads itself and your legs betray you, the rod slipping in for a moment as your legs yelp. Your eyes growing keen of a new burning heat.. You pause.. Pushing him off.. Then suddenly he leaps and impales himself on you. Despite being inhumanly fast you only manage to grab his leg.
He then kicks at you, pins your arm to the floor and flips you onto your back, he licks his muzzle, eyes rolling into predatory beast, looks up at you then reaches forward with both claw and mates you. His Long crimson penis extends once again, parting the inner walls of your muscular thighs. he plunges himself into your muscle and loins of flesh. A hot moist heat begins spreading throughout your abdomen, reaching upward and dragging up along your backbone.. It mixes with the arid morning air. Reaching into your nostrils he then darts his tongue at you, sniffing deeply.
His tongue poking you and leaves its venomous saliva coating the inside of your nose. You cough, but struggle. "Oh, please don't!... Don't!!.... " But then the images begin washing through your mind, flashing past like frames from a film, his cock stretching you wider as you lift a leg and he takes hold and fucks you hard. You try to close your eyes, and not feel it and not allow the idea to occupy the thoughts of repelling this beautiful creature who's fucking you.. So soon after giving your body for a cause.. how could this be research? Maybe needs your help.. On accepting animal semen?? How does it make sense?!??"
"I'm already doing this," you think desperately, "how does taking the dna from them mean I should fuck them?" But the cock is making you quiver and moan as you rock and roll against it.. You close your eyes in shame and pleasure. "No.. Please, don't force me..." As he thrusts himself within you, you give in to pleasurable pain.. His barbed cock rakes and opens up your new pussy as it bleeds as he breaks open your cervix and your womanhood, smashing through your inner walls and tearing open your insides as he tears you open to drain out the white hot acidic discharge he spurts and comes into you, shooting through your womb and stretching your insides out, seeping into your now tigery feline insides, spilling a creamy substance inside you that makes you even more aroused.. As he fills you completely. Hot and steaming your insides as he fucked into you wildly and left you broken in and dominated.
He slides slowly out and pulls out and pinches your neck with his clawed paws, you scream and curl up and writhe. He growls and bites you on your upper throat and back, pressing into you and forcing his wild seed deep within you and bringing out the agony and pleasure of getting splattered with his sticky sperm which slides down along your skin, coating every inch of your insides..
Feeling weak and whimpering, because if you haven't been beaten already, you are now.. as the gush flows along your face, filling your senses, smelling like fresh cum, wet and slippery, salty with the taste of his fresh saliva, this wild savor of a new experience, an unrivaled sexual encounter as he ejaculates this foreign fluid deep into you, mixing it with the rich slop of the hormone and the barbed spunk that filled you. his tail slumped between his legs, just staring at you and leaving his secretions and cum dried onto you and coagulating into ropes and strings along your ass and thigh, seeming still slightly erect.
You're still shaking and disorientated and don't know how to handle this.. The hybridization that happened to you was so unexpected.
You wondered what would happen, you'd only taken a little piece of their natural DNA to form something new. Maybe you've finally done too much...
And now here he sits before you in his beastly form, staring back and back at you while this milky liquid from his penis lingers upon you.. Gazing upon you adoringly as his huge claw-fanged paws lightly rub at your now glistening torso as your once flat breasts are popped plump and full as he kneads at your chest as the buttons on the shred of your former clothes pop free as swelling multi breasts grow out. There was something mesmerizing about his gaze as his big blue eyes watched over you like a puppy guarding a toy with beaming pride, with the most delicate and proud gaze.
Towards you..
Like he was looking at someone of significance.. or very special. And something was tugging at your heartstrings.. In spite of yourself, tears welling up.... Was it one of the original beasts for the project? Had they started out as a human like any other, or a beast from the start to extract, to be used, for profit and experimentation?
Even though you knew your feelings were wrong, there was something so endearing and sweet and sincere..
"It's okay... You are...not alone anymore..." Your voice cracks a little.
He licks at your muzzle, orange striped fur matted to thick stripes of pale white cream. And then he bites at your earlobe, pulling it. He rubs at it with his muzzle, licking at it. You moan as he pulls your ears into a tufted and curled putty. His fangs gnash and snap at it gently as he licks and bites at it softly. You shiver a little.
He crushes his tiger striped dappled coat into yours and nudges it with his sharp teeth.
"We'll go together." You whisper.
You look up at him gazing lovingly as his yellowed eye rims shine and sparkle, gazing at you. He curls his forepaws under your arms as he steps up and wraps your front paws around his ribcage and grips at your muscles. He licks each your face affectionately, holding each other closer.
Then his barbed penis painfully rakes your pussy as he pushes the black lips of your vagina open as he squeezes tightly inside you, pressing all twelve inches of long pointed barbed cock barbs into your hole. He presses his erection back inside you forcefully as you fight to regain your composure.. Once he's stuffed to his limit, he grinds his cock into your belly and bounces once, breaking the top of your now swollen womanhood, planting his barbed sex baster as deep inside as possible.
His inner cock massages the muscles of your interior as he strokes and pumps inside you, stretching you, beating and pounding you with his cock which stretches the tight walls and hardens inside you.. You shudder, whining softly in distress, your fingers fisting in the coarse gray hair of his body.. You're being worked on, abused like a cow in the market until slaughtered and sold as beef.
You tremble in painful shock and ecstasy.. Pulling his shaft hard and pressing back against him as he tugs on your tufts of pubic hair and your inner thighs as he beats you with his ramming weapon, while his wet tongue licks at your pulsating rim.. He feels good..
His hips pump back and forth, pounding into you, bending you over, banging against your cervix while you squirm, attempting to take it all, trying to take every last inch of this monstrous thing that fills you.
"Ohhhhhhh GOD!!" You gasp and moan.
And you feel yourself slowly surrender to him, feeling your insides bloom and swell, warm and sticky like flowers.. His tail slips out and wiggles itself across your pussy lips, rubbing against them softly as his long barb pricks you ever so slightly, another slit emerging on your clitoris.. It stirs and dances, stimulating you and growing larger as you continue to get pounded in, squirming against him as you lick your plump lips hungrily. His tail curves and spreads wide, pushing aside your labia and becoming thicker and wider and reaching behind, curving down your vaginal walls, digging into your pliant flesh and caressing your tender nether folds. You lift your ass up off the floor and bury your ass in the air as he pounds you, sliding up your clit with each movement, fucking up your asshole and working you over and flooding your vagina with a different kind of cum than his usual inside the endless pit of your belly.
"Take me..take me all!" you whine hoarsely, feeling more on fire than you could ever remember, and closing your eyes, willing your cunt to work harder, begging it to let him in, making your finger curl and spread your labia, slipping between them, playing with your puffy clit as you felt the manning's barbs dig and spread your opening. You are excited beyond belief, as a river of white creamy juices comes flooding from your wet womb and tickles your sensitive skin, leaking out through the edges of your pussy, dripping down your labia and running onto the bench underneath.
But it has an end. Soon your orgasms wrack your body. Giving yourself into pleasure and pain, but in this room of flesh, in the safety and warmth of the laboratory this one moment, this is your escape. Your only option. You surrender to the sensation and let go of it. You have no choice, no alternative but pleasure.. When finally it begins to subside and he pulls himself out, growling and dripping precum..
You return to the other male, and begin panting.. Pleasure faded away to flustered indignation and the giggling eyes at the females watching you take a cock make you fire up and growl, searching to reassert yourself. Growling deeply and aggressively at him as your tail brushes, blushing a crimson angry red. You lunge forward and try to growl.. but the splatter of his cum in your growling muzzle almost makes you devour his milky essence, almost causing you to cry out in surprise as he buckles under you.
You lick your fangs.. And then.. The injection stirring in your loins from his semen urges transformations like a new injection. You howl out as your human legs sprout and snake back into tiger length. You jump on top of him, raining hot breath across his vulnerable head, reaching down to claw at him, pulling apart his hooded snout and tearing at his delicate cheek. His lip turns back into a sharp sharp razor tip, fangs and jaws snapping at you as your fangs bite into his leathery lips and scrape and tear..
As your teeth reach and wrap around his throat... Not to kill.. But to claim.
You feel powerful, untamed. Instinctual. Fierce and ferocious as you rip his fleshly nape just a bit, cutting deep and ripping just the tip of his nape cheek with your sharp growing teeth, exposing his eyes as red light glows from behind the tiger eye.
You get ready to mount.. Before you start feeling confused and yowling in your own confused turn. Urges to mate.. pin and assert dominance with getting bred.. Are conflicting with the soft wet.. Feline pussy dripping between your thighs where the injection took place, fur spreading down from your thighs down to your very legs as you start to feel your feet slowly start curling up into paws as the semen leaks through.
You spend only a few seconds gawping, but it's enough for the confused also exploring Tiger to get a smile as he struggles and shrieks, biting down on your penis as you howl and jizz before you growl and become a more dominant alpha, gaining experience and realizing their fully feral body is still way stronger than you, even if they're a smaller tiger in their youthful adulthood than most, they're still the size of a full grown cougar, even if your human mind is still ahead of them, so while still definitely winning.. This competitive edge, is making you battle ferociously to maintain your dominance over them.
Your tiger claws have curled and sharpened like talons, and now both your feet and your hands have rounded into tight felines pads. Your abdomen's breasts continue to swell, popping through the top of your navel slightly, moving lower and pulling together, and forming as plump and tight as possible at your crotch area.
Long spotted stripes cover your skin, overlapping as the snow leopard serum spreads like butterfly wings down your own body's chest and sides, your musculature and busts both increases dramatically, making you look more and more as strong as a alpha beast, but as plump and filled out as a she beast. Even though it's partly due to this experimental serum.
Still, with this wild hunger, this impulse.. You're taking your rivalry too far, wanting to prove you're alpha.. It's too much.. Even if it's with your own genes as well as those of the hybrid you created in your drug induced haze.... You yelp as the complications of getting mounted spread with the injection. You're now longer pure male.
Instead.. A tiger-she devil mix of lust and dominance and nature of domination grows in you as you become hard, as you become.. Something needier.... With your core still going through the initial stages of transformation. Eager to mate again. All of this heightening arousal with so much desire and competition is scaring you. Despite all the physical change..
Tears of frustration slip down your nose, your black hair waving a little more as you try desperately to grip onto your power as an alphas. Growling and clawing at this opponent with such ferocity.
Your tiger mouth gapes wide as the Tiger gets caught up with his own instincts, and mating begins. Your own wildness and beast pushing the spark to combustion.
You're becoming softly almost addicted to feline DNA and semen of any kind now.. The snow leopard dna now, it makes you feel better. Comfortable. As you breathe heavily across each others' faces, roaring and fucking and clawing at one another in eager heat, sweat coating your bodies. Screaming.. Sometimes climbing atop the Tiger and growling until you smash into each others backs, locking your jaws together to help keep your own fangs as long and sharp as they can be, maintaining your position atop the other feline sex god.
And then, when the storm passes, you fall and roll off the small table to land on your bottom, panting loudly, losing your ability to roar for a moment as your transformed voice changes and quietens.
You know you can quit any time and kick it, but it just feels right.. It's like a caffeine injection of energy and wild vigor.. Without it, you fall into a slump and you'd be fine.. But it feels so good to get that mild fix.. You feel almost content, almost like you could last forever, you look into their eyes and raise your paw to maul your own. To bite your muzzle playfully. Your forelegs twitch forward and you squirm with contentment and desire, and you fall forward like a lioness falling on her prey as you snap your jaws down and tussle with your their muzzle, playing like children as your tiger cub falls off and rolls as he munches on your lips.. Not quite content to submit fully.. You move into a 69 like position and start to suck the tiger's cock with idle curiosity while offering him your cock and pussy.. Chattering happily in love with this ritual playtime as your jaws release each others' inner fur-covered orifices.
Now your pulse beats faster and more violently, the idea of joining your fingers and plunging them deep inside of something.. Being filled so deeply is such an exciting thing.. Your snow leopard and leopardess crossed dna feels proud to be such a successful specimen of species, to have gotten so far as you have.. It thrills you to think that you may well go on to have a litter with him.. Of kittens who will live to see the future in this world..
Of healthy reborn endangered species kits with majestic plush snowy fur and leathery flesh covered with multicolored stripes and spots running along the length of their sleek muscular bodies. Of hunting skills and predatory habits that set them apart from the other felids. They'll eat meat, deer and buffalo as well as the occasional small game bird, skunks, and sometimes carrion from settlements as well as snow mice and ferrets. You'll name your litter after the moon and stars that currently graces the night sky..
As you roll in pleasure from your contact with this tiger as he bites into your arseholes, sinking his fangs into you teasingly.. And finally giving him a blowjob.. The taste of sperm washing down your throat. And swallowing it down hungrily. Your face starts to push out, transitioning from partially feline to full on anthro leopard, before another gulp flushes the last remaining whites of your eyes as your body becomes a feline snow leopard from head up, and soon your paws follow suit as you lose your once nimble dextirity to fall on all fours like a animal
"Oh fuck," You moan happily at your animalistic instincts taking over, "Fuck, I'm going to be breeding you! Fuck!"
The tiger doesn't say anything. He just pounds into you to celebrate the success of mating with you. And when you cum he drinks your semen eagerly. You're at ease and happy to let the tiger take over, mating with you entirely, only coming to a climax when you finally allow yourself to recover fully, your brain returning to its human consciousness again. You still breathe heavily and pant as you pull your feline form back to kiss the unconscious Tiger. You crawl up and snuggle him close to you before turning around, pleased that you were able to enjoy yourself.
Soon one of the girls can't wait and Zenevia strokes your cock while the tiger mounts you and you lose yourself, and mount her turning it into a threesome orgy at the researcher's request. You don't even notice the camera's recording you, or the little robots recovering all the spelt semen.. Only that it feels so good to be a animal so satisfied after submitting so hard to just being used as a submissive toy by many different animals before finally being fucked for everyone to record.
