An unfamiliar man enters the room, and stands in front of you. He speaks in a softly yet authoritative tone..
"We are entering the second portion of testing. These portions will test your physical endurance, mental capacity, durability, pain tolerance and more.
This is going to be an adventure.. Or horrifying, you can never tell.. They pull out a syringe, dripping some clear fluid into your thigh.. Holding your leg by the crook of your knee as they prepare the needle.. Pulling back, you start begging, so horrified and helpless. You feel a spike in pain as the needle pierces your skin, stinging, and blood flows out of the entry point as they pump in the experimental stuff, in your now lubricated muscles.. Hissing deeply.. You're put in charge of keeping yourself still, you need to control your legs so they don't jiggle or kick you as you don't want them making you bleed further. You brace for the unknown.
With determination, a sense of urgency, and focus.. The ride lasts hours as the liquid seeps in your muscles.. The increasing pain combined with the stimulation makes you feel weak and vulnerable. Deep breaths and breathing techniques bring you back to life, eventually. They stop pumping the serum into your thighs and find a large bag filled with ice wrapped in towels.. Draining you of the warmth and putting you in a chilled state.. During all this, your jerking, twitching.. Attempting to keep control.. You gasp as the hand gently presses against your pelvis.. Between your legs.. You feel small soft hands slide your balls in and fill with cool gel.. Then they massage it between your glans as they hold your entire package together.. You realize its coldness, gel dripping onto your bare bottom.. Glancing over and realizing they use those dark rubber type materials. What on earth is going on? Now its fucking cold against you.. Swallowing and trying to catch your breath, every noise so frightening.
"Time is precious my friends.. We'll give you 10 minutes.. That's enough time for you to become accustomed to your surroundings. You'll sleep while we take measurements and test all that's possible. I think you will need our help before this night is done..
You feel them opening your body as they bind your head and lips. Pushing a water bag in with a straw sticking out and give you mouth suction cups to suck on.. Taking long timed drafts. Lifting the water bag again to refill, noting their glances to your thigh as it fills.. Next, check under your arms and down towards your hips.. They lightly massage the pressure points, applying warm oils and some lubrication for a comfortable journey..
Suddenly, you feel an unexpected stream of liquids dripping down your butt cheeks. You jerk, frightened. They remove the cloth bound bag, attached with many other similar bags, and the scientist who was doing this looks pleased. Opening a box of lubrication jellies he drizzles some on the center of your mound, soaking it deep with the glove touching you..
He moves your lower half upward so he can spread the jelly in place with a medical stick.. Hand still gripping the test tube as the other rests with both palms on your waistband and pushes the stick straight in your belly, pressing downwards.. Pressing against the outer skin, gasping and squeaking as you feel the wet fluids soak deep in your insides..
Suddenly they start bringing in a weird, glass tube, contraption with a white bag of cum and cameras. An artificial insemination machine.. Filled with.. Your nose scents.. With a gulp.. Human cum. From a donor.
"Your donor for this project has been very generous and very specific. Now.. Don't worry.. We've made sure it's all safe and you won't have to worry, all of you are completely sexually healthy individuals and we even cured a few other miscellaneous conditions you both had.. He's paid for this fun with you. Now be a good little dear, and struggle. He said he wanted it to be
pleasant, so why would we disappoint him.. Make you enjoy this?"
They begin pulling the bag out, and lets the sperm roll out into a shot glass, a gallon jug full of semen..
"See, how nice.. It's all squeaky fresh and oozes like spunk.."
They squeeze the fresh cream into your two waiting globs.. Strange noises leak out your throat and when they hit the floor, all toiled up and rolling out a huge slick tube of raw and sticky sperm is injected to your newly formed pussy folds. You quiver and try to fight, but you're bound too tight as you scream and chitter.
Your hole is invaded. Its pressed open, drenched with the new cum, and a steady drip of slippery rich paste trickles out.. You sigh loudly, inhaling deep gulps of air as they inject you twice more.. fluids being sucked back out, getting lubricated by saliva, before starting all over..
They watch you and your squirming.. You're begging for mercy and not allowing the bucket with your pussy being breached to drop back to the floor. You struggle and fight as best you can.. Frustrated.. Breathless, eyes glued to the mirror. Looking past the men.. Seeing nothing beyond themselves and a couple others in lab coats watching with plastic boxes in their hands. A handful taking notes.. Telling one person they need to look at your ear in the mirror because he just keeps running his hands in that direction. You hear his question about the ear and are looking back in the mirror at them in panic.
"Whoa.. Look at that ear!" exclaims the one man as you step back in horror.
"What happened to that?"
"Oh my god. I saw the symptoms earlier. And you look exactly like some pictures online.."
"Excuse me?!?"
"That research I signed off on a few years ago!!"
You moan as you howl out as they continue to breed you with the donor's semen.
You're in heat and its hot.
Your mind is split with hatred, betrayal, shame, and lust.. It feels good. But it's not what you wanted.. You whimper, it burns.. You.. You n... need it.. Everything was getting tighter and tighter until finally, suddenly the expanding pool of cum started to bulge against your held pussy folds as you clentched, the cum stretching and contracting to a larger and bigger size as it took shape. There was nothing to hold the sexual fluids back from sliding in, causing its bulge to lengthen and pressing on the engorged nub of your clitoris, massaging it in their sperm as the juices leaked
You hear footsteps as someone approaches your cage. But they've gone silent, you can only hear the snap, click, whirl of camera lens. You shudder when the door opens with the weight shifting and sliding across wood. Reaching into the cage, grabbing the long chain attached to a collar that snaps right onto you. Your collar... you whimper as you realize you're becoming a bipedal sexpet for someone..
Cuffing you in it with the clink as you try to bite it and fight free. Realizing you can't, you arch your back and let out a high pitched wail as they enter the room, yanking the chain to drag you along with them. You whimper as they push you to a metal table, shoved with your wrists tied behind it.. Hands checking, eyes searching as one raises your pants to check your pussymound. Noticing a different hair color. Looking confused, raising the waist band and seeing another brownish thick patch of fur.. Another one already present, lower than before. Eerie, stroking it, gazing, noting the glossy shine.
"But.. But.. This isn't mine!" they mumble
"Yes. Of course. It's yours."
You're completely naked from the waist down, feeling exposed and vulnerable as you stand before these people who examine you and talk about you as if you're less then human..
"They were supposed to have a cock.. Weren't they?"
"Well. We don't know what causes that. How they lost, or gained such a growth." One says skeptically, "Maybe with the mass addition of the arm growth.. it decided a non vital organ to diminish was unnessecary, and sucked away the penis to make more mass for essential muscle growth and agile legs? After all. Cheetahs are known to be king of speed, and for athletes, females are known for lower body strength and running. Maybe the serum adapted and didn't see breasts as necessary to performance, and sucked their cock away to make what it thought would be the most aerodynamic. A cheetah cunt male, without bulky breasts, but 8 feline nipples and a very tight and compact slit.. Their cock is still there.. Only just as tiny as a clit.. and just by habit and force of being sucked in.. he almost has a fully functional vagina now, although his dna is still biologically male. Anatomically.. It's a infertile psuedo pussy that leads no where. But this next injection should correct that, and restore all biological reproductive function" they mumble, rubbing the new sprouting fuzz, "Why does it appear so...Suburban? Dense?"
"It must be natural causes. Maybe from sperm in the area that stimulated the increase.." another adds
"What could do that?!..."
"Don't look so shocked. Our own experiments have led us to believe that.. Incubation effects might happen in a local habitat with extreme rainfall and humidity. We injected male cheetah DNA, for all rights and purposes.. They should be male.. But maybe their body still thought it needed to adapt to provide a orifice for breeding"
"So far we've seen only the increase in length of your tails and ears. Other organs should have been effected.." the second one remarks rubbing your short sunny spotted hairs, pulling out and smelling them.
"Maybe a condition, possibly something we missed in our research?" the first continues..
"We may just run tests on samples of sperm collected directly from their furry cunt. Perhaps we'll see something.."
"Perhaps...." they mumble.. And then they proceed to grabbing the next instruments.. What will happen next?
