#1 of Lab Rats


(My first story ever! Bare with me on the crappy Word formatting too.)

Sandy sighed a bit, the large white-furred rat leaning forward in her office chair as she scanned the email in front of her for what must have been the tenth time since she had received it. She had been working on a fertility enhancement regiment for nearly three years now, with limited results.

'....we regret to inform you that clinical testing for your most recently proposed drug, PXT-010915, has been rejected. We feel that there is not sufficient evidence based on the trials provided to justify the cost of moving forward with phase 2 trials. If additional studies provide evidence to support....'

"Bah!!"

She blurted out, covering her mouth with a clawed palm before looking around shyly, though it was already 6pm at the small research and development company and there was likely no one around to hear her outburst. The rodent gave another grumble, slowly trailing one of her red-painted claw tips along the surface of her desk, making a light scratch mark. Additional studies? Not likely, there was no more funding for this project, and she was so close! She knew her formula worked, but testing it on lab animals just wasn't producing the results she wanted...there was something missing from the equation. Suddenly though, as if out of nowhere an idea seemed to pop into her head.

"Hm...what if....the missing piece has to do with the feral nature of the test subjects?"

Tapping her chin lightly in thought, yes that could be it. They had done so many tests on those small feral lab rats, a mixture of effects seemed to manifest, but none mirrored the results they had been expecting and hoping for. The treatment was never designed to be used in a feral after all; this was something for the two-legged population of her world. Just then the female slammed her fist down onto the desk, a slight smirk forming across her lips. The plan had already been hatched in her mind, she had plenty of the drug laying around from her various studies....definitely enough for dosing a larger animal, 65 kilograms or so should do it.

With that she set to work, standing up slowly from her chair as the rodent's large and plump bust pressed out against the rather snug material of her shirt under her unbuttoned lab coat. Her long thin tail swung back and forth through the air, whipping slightly against the door frame as she walked out through the door into the wet lab. She would spend the next few minutes scribbling notes onto a pad of paper, calculating various weighs and measurements while leaning over to the side and tapping a fine powder onto the scale in front of her. The powder was added to a small beaker before being filled with water to dissolve the mixture, quickly forming a milky white suspension before her eyes. Sandy gave a slight lick to her plump lips at the devious nature of her little experiment, no doubt the last she would ever be conducting at that company if anyone caught wind of her little plot! She would need to come up with a cover story...hmm perhaps some spilled into her drink? The amount was not that much so that her story would be un-believable after all.

Several minutes later the fluid in that beaker began to turn clear once again, the white powdery particles having dissolved into the water. It was done, the ticket to finally proving that she was a true expert in her field sitting on the lab bench before her. She felt slightly giddy at this little excursion, just what would happen after all? Would everything go just as she had expected in her calculations? This was no time for regrets or hesitation though, and with that the beaker was quickly snagged into the firm grasp of her paw, tilted up to her muzzle and thrown back with a few deep gulps.

The liquid was slightly salty, but also had a tone of sweetness to it... some of the chemicals in the concoction having a similar molecular structure to that of dextrose after all. Sandy licked her lips a few times to get off every drop before sitting back onto her stool, setting the empty beaker into the glass wash machine and turning the power on; just one step to cover up evidence that she had done any wrong-doing in the lab that evening. The next would be to tear out that page of notes and calculations from her pad of paper, folding the piece and stuffing it into her shirt pocket before giving it a few light pats.

"They will never notice that quantity of chemicals missing, we went through a hundred times the amount on our last study alone!"

She thought to herself reassuredly, cleaning up the lab bench and tossing a few paper towels into the trash before wandering back across the hallway to her office. The rodent settled down into her seat slowly, pulling out the keyboard drawer as she started to tap away at the keys; Sandy still had quite a bit of work left to do after all....she had been brooding away the last few hours over the final rejection letter received from that pharmaceutical company.

Half an hour later Sandy gave a slight grumble, she had not noticed any effects at all from the mixture ingested shortly ago...wondering if there was going to be any at all. She sighed a bit, resting her head down onto her desk as her large rodent ears flicked and swiveled around on her head, vibrating slightly in the air. It was certainly warm that evening, didn't they ever turn on the air conditioning in this place? Sandy thought to herself, sitting up in her chair and standing to slowly remove her lab coat...she was wearing clothes underneath it and was not going to be in the lab any more that night after all.

Sandy slowly walked over to her door where she hung the coat on a coat rack standing beside it, a full length mirror adorning the back of said door. She couldn't help but smile a little as her form was revealed in her none too revealing attire, a simple blouse and skirt that came down to around her knees. Her head shook a few times, letting long silver hair brush back and forth across her shoulders. Large, full breasts pushed out against the fabric of her top, jostling and jiggling slightly with every movement she made through the office. One clawed finger would tease down along her side as she admired her own reflection in the mirror, her slightly plump frame filling out the material of her outfit quite well...she was certainly no skinny little rat after all! That same paw moved to brush across her stomach, a bit of her silky white fur exposed to the air by her movements. Wide hips would work to strain the material of her skirt as well, slightly plump thighs hidden under it. Lovely long legs would follow those hips, trailing down to dainty little foot-paws which were held in low heels.

"Mmm...not bad...."

She smiled, continuing to admire her own reflection; though the room seemed to grow even warmer even after shedding that extra layer of clothing. Sandy walked over to the corner of her desk, switching on a small fan as a cool breeze washed over her face, causing the rodent to murr happily in appreciation. Still though, that pesky heat only seemed to persist on, her ears laying back against her head and giving another buzzing motion. The female pulled her chair around so that she could sit in front of that powerful little fan, letting the cool breeze wash along her body now, giving a contented sigh as the air teased along her fur. The clothing seemed to still be too much for her at this point, hot under the single layer of fabric covering her form. She looked around before smirking lightly to herself.

Why not? No one else was around after all....

She would giggle slightly, the female running her paws down along her blouse as she slowly worked to unbutton it, pulling her arms through and letting the material fall to the floor. Next was her skirt, unzipped and pulled off from her wide hips and slightly heated fur. Both articles lay in a crimpled pile on the floor beside that curvy little rodent, now clad in only her silky black bra and matching panties, covering up those delicious heated treasures. Sandy had a nice view of herself in the mirror from this vantage, sitting back in her chair and grinning widely as she watched her own movements, slowly trailing one of her fingers up and down along the silky fur covering her long leg.

"Yes yes, not bad indeed. Even lovely I might say..."

She complimented herself, though she would be damned if that heat did not persist even through her removal of clothing and position in front of the fan. In fact, as she watched her own nearly nude form wiggle around in front of that mirror the rodent only grew more and more heated, starting to pant slightly with her tongue hanging from the side of her muzzle. Every touch along her frame seemed even more...intense than it normally would have been, slight shivers of heat running up and down her spine, down to the tip of that long thin tail. If just a simple touch along her fur felt this good to the rodent, how would even more feel? She giggled at the thought, though let out another heated huff into the air at the intensity of it all.

Ever so slowly the rodent's long finger slipped under the lacy material of her panties, the tip coming into soft contact with her heated little folds under the covering. Instantly she shivered as a tremendous wave of pleasure ran through her body, the rat's toes curling as she clenched her teeth together, an almost feral hiss filling the air around her. Those waves of pleasure continued from the simple act of touching a finger to her heated sex, moments later a thick splash of heated and scented juices squirting against the lace of her panties and dribbling down along the fur on her thighs.

Sandy looked down a bit puzzled, still huffing lightly in pleasure as scented fluids continued to slowly drizzle down along her thighs, prompting the rodent to stand and slowly remove the now soaking wet material of her panties. She would step closer to the mirror in order to get a better view of things, looking down to those swollen and puffy sex lips, radiating heat into the air and still drizzling with moisture. Had she cum that easily, just from touching herself? What had gotten into her?

With a slight whimper she would again explore her fingers down along those heated folds, using two this time as they slowly curled and pushed between her glistening lips. The two digits pushed up to the roots as she sank them into her obviously needy sex, though the rodent may not have been prepared for what happened next.

"Mm..mmmphhh... fuckkkk!!!"

She screamed out, thankful that no one was around this late into the evening. Forced to lean back on her desk against the paw that was not stuffed between her thighs, the rodent's back would arch sharply as her ears flicked in pleasure. Thick feminine juices squirted out from around her fingers, splashing out into the air at the same time they drooled and drizzled down excessively along her thighs, a few patters being heard as droplets hit the floor beneath her. A slight shift of the paw between her thighs caused yet another bolt of pleasure to rush through her body, that second orgasm overlapping with a third and fourth. Sandy's body twisted slowly as her plump little rear sat down against the desk now, panting and huffing lightly before raising those juice-coated fingers to her lips, licking the slender digits clean.

Just then she would shift forward slightly, a heavy weight against her chest. Just now noticing that her silky bra felt abnormally tight, the material strained and stretched around those heavy globes on her chest. Without a second thought the rodent reached back and flicked open the clasp holding her bra on, a loud snap echoing through the room as the elastic flung open and flew around to the front. Off would come that strained material, falling to the floor below and revealing the rodent's heavy chest to the mirror in front of her. They were definitely bigger, she thought, stiff nipples poking out through her thin fur.

So delicious...she thought; the paw not stuffed between her legs raising up to press against the side of her chest, though that plump breast would not fit entirely in her small paw even before their growth. The rodent could only guess that once her perfectly rounded DD's had grown several cup sizes, maintaining their lovely shape all the while though. Two fingers worked to slowly tug at a thick sensitive nipple now, tugging lightly and rolling the sensitive nub between her fingerpads. She needed more, and right now. Laying back onto her desk as various papers and objects were tossed aside carelessly, the rodent tugged harder at her plump little nipple....all the while her other paw would go to work between her thighs, stuffing three fingers now into her hungry little sex.

"Ahh...ahhhh yes!!!"

The rodent growled now, pleasure flooding her body as a slow trickle of creamy white liquid squirted out from her teased nipple, raining back down onto her muzzle moments later. Sandy arched her back sharply on the desk, kicking her legs as another wet spray of slick feminine juices drizzled from between her thighs, running down the edge of her desk and onto the floor below...the thick smell of sex prevalent in the room, a sexual haze shimmering in the air around her.

And still, she needed more...it was going to be a long night in the office.

Finally, the last three years of work was going to pay off....

To be continued....?
