A Weighty Experiment

Giddily, a silver-furred deer clenches her fists in glee as she awaits the thing she’s been waiting to see all day. Getting permission from the Medical Research Institute was a dream come true when she proposed her hypothesis on how fat settles on other people’s bodies, and now that she managed to make that a reality with her research, she could positively scream out of joy.

The scientist was a chubby woman with chubby cheeks which were begging to be pinched. Her bust was large enough to overfill her hands whenever she cupped them, and she did find herself staring at them more often than not. Her rump was also just as large, causing her trouble whenever she tried to put on jeans (but when she did, she drooled at the sight of her ass almost splitting the seams apart). Her tummy was also relatively large, pooling over her crotch whenever she sat down, which caused a lot of trouble whenever she was in the mood. Her arms and thighs were thick enough to make any teenage boy want to rut her right then and there, but she was happy she was single. It allowed her to get more frisky whenever she was alone...

Speaking of, she could hardly contain her excitement as she walked towards the door, gripping the handle as she imagined all her subjects in the test. They had all agreed to take part in her studies, and it helped that they were all female since that meant she didn’t have to do two lots of subjects for the studies. The formula was simple; a few hundred millilitres of her fattening serum which boosted appetite and lowered metabolism, and a few tons of food which would make any large family sick, and then her research would be good as done! This was the last day that her subjects was going to be a part of the research, all of them being laid off the day after today. With bated breath, she opened the door, taking in the sight of all of her guinea pigs...

Truth be told, it was breathtaking. To any doctor, it would also be breathtaking. There were four cells, as wide as a large prison cell to give them space to grow and to walk around, and she was surprised when she saw that quite a few of them were beginning to fill that space out, little by little. To save the embarrassment of ripping their clothes, all of them were nude, leaving nothing to the imagination as she wiped drool off her mouth. “Time to find out if my hypothesis was correct or not...!” Whipping out a checklist filled with boxes and spaces to write little details, she set forth, beginning to peer into each cell with a perverted—ah, curious grin.

The first subject was a cat with black fur, yellow-greenish eyes and black hair which reached past her shoulders. Prior to the experiment, she had been a sporty girl, priding herself on all her achievements she got during games of soccer and tennis. However, when she was approached by her for the experiment, she had immediately quit any form of exercise, firing her personal trainers and instantly agreeing to the experiment. When she was asked why, she replied with a few sentences and nothing more. “My wealth can keep me afloat for the rest of my life. I’ve always wanted to do this.” She was a woman of few words, and never said more than she needed.

Which is why it surprised the deer that she was moaning so much.

The athlete was a shadow of her former self, her entire body taking up half the cell’s space because of all her blubber. She was a natural pear shape, her ass being the one body part that sticks out the most; two cellulite-ridden globes wobbling about as the cat’s hands kept groping and jiggling her flesh, her vast thighs quivering as she desperately wanted to pleasure herself and tend to that pussy. Her bust had only moved up one cup size, staying at a C cup no matter how much she ate. Her belly was also relatively small, only a sizable paunch being where most of the fat should have gone. The cat kept suckling on a tube full of heavy cream, her chubby cheeks bulging as she took more and more large gulps of the fattening liquid, moaning and sensually slapping her fat ass all the while. She dared not to open her eyes lest her pleasurable experience been interrupted by real life. “Mmph...”

Biting her lip, the deer hesitantly looked away, disappointed that she had to look away from the fantastic display of gluttony. Adjusting her glasses, she sighs in happiness, before moving onto the next cell, her “excitement” showing via the blushing on her cheeks. Looking inside the next, she damn near squealed as she saw the girl happily suckling on the tube of heavy cream.

The second subject was a patriot through and through. In the country all the characters of this story lived in, she had to be the one that knew every single nook and cranny of every single acre of their land, singing national anthems and adorning their house with the flag. She was a caramel-coloured dog with auburn eyes and brown hair who placed their country before their own, and vehemently opposed anyone who dared to claim it was anything less than the best country ever. When she was asked to participate in the experiment, she was on board when she found out this would have helped her country in the future with any weight-related projects. “Hell yeah! Count me in, dudes!”

By the way she was greedily, practically deep-throating that tube, the deer could tell she was having a good time.

Prior to the experiment, the girl was lithe and rocking a six-pack from many hours of working out to better her country’s image to a near-utopian like level. However, she had disregarded that, her body now looking more like a bloated blubber-filled sphere than a dog. Her ass, compared to the cat’s, was small. It was just as large as two yoga balls, laughably small in comparison to hers. On the contrary, her tits were massive. A G cup causing her to arch her back with each gulp of heavy cream, the deer damn near started schlicking every time her massive bust sloshed with each gulp. Her belly was also favourably large, hanging to her thighs as she tenderly groped it with happy whines and groans of pleasure. Her double chin quivering, the dog looks towards the deer and waved, her flabby arms jiggling and wobbling the whole while, still drinking more and more heavy cream. It was honestly mesmerising to the researcher, a fact the dog took advantage of by winking and slapping her belly, causing the dog to whine out of even more pleasure.

Weakly waving back, the deer wasn’t sure she could take any more of this. She was just going to give up and lose any self-control if she sees one more fatty greedily sucking that tube... “Wait,” she remembers all of a sudden. “If I do, then their concentration will be broken and they might mess up the results! I don’t want that!” Her resolve slowly weakening the more she thought about it, she shooke her head, her perverted grin going strong as she looked into the next cell.

The third patient was a foreigner... Well, to be more specific, an immigrant from a cold country into the north. She spoke fluent English, allowing them to communicate clearly—as a bear, it was kind of needed to get a job in the country. She had brown fur and spoke with a motherly tone despite being the same age as the rest of the subjects, which was 24, and not a day later. With golden eyes and a relatively plump body, she had always carried herself well around others, acting modestly and not daring to hurt anyone around her. She hadn’t had a good supply of food when she was younger due to the cold, so she was instantly hooked as soon as she heard that she would be payed for eating.

This helped her a lot as she kept drinking more and more, years of a suppressed appetite coming back to strike her.

Unlike the other two, her body wasn’t exactly an hourglass shape and it definitely wasn’t anything to note of. Her bust was a D cup, which jiggled around no matter what she did, and her rump was as large as beachballs. Honestly, had it not been for her massive stomach, the deer would have skipped her for not being interesting enough. The bear’s fleshy abdomen was sticking out enough to cover half of the cell, pooling on the ground as it gurgled and groaned for more and more food. She rubbed her blubbery gut, moaning as she kept suckling harder and harder on the tube. She just stared lustily into the ceiling, mentally cheering as she kept thinking that she had almost drained the whole supply dry... Before more heavy cream came into the hose, causing her to close her eyes and just keep sucking. She could have sworn her belly began touching the wall with every single gulp, but it wasn’t there just yet. Disappointed with the revelation, the bear just kept sucking, filling that void with more and more cream...

“God,” the deer mutters to herself as she slowly slinks away, swearing that a dark patch has appeared in her jeans, causing her to bite her lip again. “I can’t take much more of this. I gotta...” Her voice trails off as she peers into the fourth cell, gasping at what she sees. Not out of shock and concern, oh, no. More out of surprise and curiousity at what she sees. It took all of her willpower to not have her knees buckle forward at the sight of the fourth subject.

The final subject was a silver mouse with platinum-blonde hair which was styles in a pixie cut and black eyes. This mouse was actually a good friend of the deer’s, and actually had a fetish for gaining weight. Prior to the experiment, she had been skinny as paper, not being able to gain weight due to her absurdly high metabolism. The deer wouldn’t have admitted it, but she kind of thought she would have looked better as a plump beauty. She had actually approached her first to take part in this nation-changing test, to which the mouse squealed in delight before frantically signing her name and hugging the deer tightly. She wouldn’t have admitted it, but it kind of felt good...

But it sure as hell wasn’t as good as seeing one of her friends as a fat blob, sucking that tube like it was her life force.

The mouse was the largest out of the four, her mass covering the floor and touching the walls as she kept jiggling just from drinking the fattening liquid. Her ass was as large as an elephant’s—no, LARGER than an elephants, quivering as the mouse kept fingering her pussy using one fat arm which was like a large ham. She had forgotten all restraint an hour ago when she first touched the wall with her belly. Speaking off, it was the largest thing about her, its vastness dividing into three rolls and gurgling for more despite being as fat as possible. Her breasts were a double J cup (was that even real? The deer would have to check later), hanging like sacks of lard as they slowly enlarged, and with that, her sexual appetite. Her legs and thighs laid uselessly on the ground, supporting her fat as she slowly spread them further apart with each mouthful. Slowly, but surely, she turned her fat neck towards the deer, staring with lust as she felt herself inching closer to climax, before closing her eyes, and...

When the mouse climaxed, the deer booked it, the dark patch becoming more prominent and more needy. Opening the door to an office, she picked up a letter and began furiously writing into it, finishing in record time and rushing back to her room for a good time. Now, as with all creatures, her privacy must be respected, but the letter can be shared as she would have wanted everyone to read it. Below is the entire letter, which isn’t very long;

“To the Department of Medical Science and the Weight Division,

I humbly request you allow me more time to research the effects of the human body and what happens when the weight limit is reached. As it were, the current results cannot bring me to a conclusion, and I believe this would be rectified with more funding and research. Please consider this, and I am waiting patiently for your answer.

Sincerely,

Lilly”
