In a comfortably furnished office in the highly-successful Kei Corporation, a petite pastel blue bunny sat behind a desk looking at the two seated before her. The bunny was dressed in a more work-casual way today; white blouse with a ribbon around her neck, black skirt that hugged her hips in all the right ways, sheer black stockings fastened in place with a garterbelt and heels. With her long, floppy ears tied behind her head and the thin-rimmed glasses on her cute nose, the bunny looked like the least intimidating employer in the world. Almost like she was trying the 'sexy librarian' look but not having the right proportions. The bunny was short, barely five feet tall and while she had quite the cute butt in that skirt, she lacking quite a bit in the chest.
Still, the skunk and colt sitting before her desk were in awe and fear of the bunny. They were in an interview, after all.
"Good morning," the bunny chirped with a cute, beaming smile and very feminine tone. "My name is Katie, feel free to call me by my first name. 'Mrs. Hopskins' sounds a bit too formal for me. Oh, I hope you don't mind I interview you both at the same time. If we're going to work together I feel it important to get to know your coworkers."
The colt and skunk looked at each other and shrugged.
"Great!" Katie said with a clap of her slender paws. Now let me hear a little about yourself, hun. You're Keiko, right?"
The skunk stood the moment his name was mentioned. "Y-Yes, miss," Keiko said in a high, girlish squeak. He was a femboi, about the same height as Katie with girlish proportions and dressed in a way to make those features more apparent. Keiko looked like a raver, in tight neon blue bootyshorts (that cupped his very small package nicely) and a matching mesh top that did nothing to hide his pink nipples on his perfectly flat chest. A decorative choker with a little pink heart charm dangled from his neck and his short white hair was clipped in a poofy pixie-cut. His tail stood out the most, a huge, fluffy tail that looked like it would feel soft as a cloud; Keiko clearly kept that perfectly groomed.
"What made you want to explore a career in potion-brewing?" Katie asked sweetly, her glitteing green eyes focusing on Keiko's own brown eyes.
The skunk waffled a moment before blushing and sinking knock-kneed into his chair; even his mannerisms were eccesively girly to the point of being a fetish. "W-Well... I've used a lot of Kei Corp's potions and, well, I had ideas on new ones to make. I know I need to be a tester before I can make new potions but... b-but I've always wanted a job like this, testing Kei Corp products!" After the last line, Keiko clamped both paws over his muzzle and blushed. "S-Sorry, I get nervous in interviews..."
Katie smiled again and nodded. "No worries, hun," she said soothingly and turned to the colt. "And what about you, Sasha? Same question."
Sasha didn't stand but crossed his legs. He was a femboi too but a different type thanks in part to his equine nature. Sasha was taller than Katie and Keiko but only by a few inches, the flowing dress shirt and slacks he wore giving him the air of a playboi who knew how to make the most of his looks. His chesnut coat and sandy blonde mane only helped this look, his mane looking every bit as silky soft as Keiko's tail. Every now and then, Sasha would give a little toss of his head and let his mane sweep from one side to the other.
"Similar answer," he said in a smooth soprano and another toss of his mane. "I'm interested in the 'alteration' side of things, you know. I figure I can make some great changes to how somet things are run."
Katie's smile didn't waver as she stood and walked around to one side of her desk. "A guy with big plans?" she giggled and surprised Sasha when she sat on his lap, gently straddling him and resting her thin arms on his shoulders. This had the desired effet as Sasha's 'too cool for you' attitude cracked away as his eyes went wide and he blushed deeply.
"I-I, you know," he stammered, his voice raising a little as he tried to look away. "I wanna try new stuff too... n-not that I have to work here for it."
Katie giggled at that. "Wow, a little tsundere, huh?" she tittered and gave the colt a kiss on the cheek before standing and moving back to her desk. Reaching into a drawer, the bunny continued to speak. "Well, you both have the attitude for this job, but there are two tasks I need you both to perform as part of this interview."
"What's that?" Sasha and Keiko chirped in unison as Katie sat back in her chair with a little blush on her own cheeks.
"Undress each other." Both bois blushed and said nothing as Katie went on. "Working in this field requires that you be more than comfortable with each other. The potions we test must be tested on each other to ensure we get the best results. Keiko, I picked you because you're adaptable and can roll with anything we throw. Sasha, you have the attitude of a secret kink that will help us further research and development here. So, please undress each other."
Soon, Katie's blush seemed burned into her cheeks as she gazed at the nude fembois before her. Keiko's outfit had been so revealing that only the exposure of his cute butt and tiny package was of any surprise. Sasha was another story. To go with his height, the colt was very fit and possessed the professionally fit body of a runner or dancer. Or both. His thighs were amazing and he had the hint of a six-pack, but despite the muscle he was still so lean and feminine... until you got to his own package. Sasha was properly hung, a thick equine sheath twitching as the colt became aroused by Keiko's nudity.
They would both go far in this job.
"Very good," Katie moaned, not even hiding the fact that she'd been toying herself the whole time. Her two new assistants seemed to notice as they both began to grow differing erections. "Show me how well you can work together, please... oooh... <3"
They knew what to do and their roles were clear the moment they were in each other's arms. Sasha was the dominant one here, embracing Keiko and kissing the girly skunk boi tenderly, slender hands reaching down to stroke and squeeze anyplace that made the skunk squeak. Before long the two were embraing before Katie, gasping into each other's muzzles as their vastly difference cocks rubbed against each other. Fully erect, Keiko was a mere three inches long while Sasha sported a generous eleven inches. Their frottage reached a high point as they started frantically rubbing against each other until Katie stepped in.
"W-Wait! Don't cum yet!" she squealed and stood up, racing around the desk at once with two vials in her paws. Both Keiko and Sasha stared as the trembling, panting bunny stood before them, whimpering as the surprisingly long and thick toy she'd been using slipped free and dropped from beneath her skirt to the floor. "D-Drink these... then fuck me. Please!"
The colt and skunk obeyed at once, each downing the offered potion. Without waiting to see the effects, Katie knelt down in front of Sasha and eagerly started licking and kissing his cock. The surprised colt could only blush and moan as his soon-to-be employer took him into her muzzle with surprising ease. Keiko was moaning for a different reason as his unique potion took hold and he watched his own miniscule cock grow into a healthy eleven incher just like Sasha's. 
"Whoa... this is so cool!" the skunk squealed and stroked his new huge, sensitive length. "The balls are a bit too big for me, but it's neat having a nice big cock. <3"
"Mmmhh... <3" Katie moaned around her mouthful of horsecock. Reluctantly, she pulled off with an audible slurp and stood up, bending over her desk and wiggling her skirted rump at them. "P-Please, fuck me!"
They moved as one, reaching out to yank down the skirt and lacey black panties beneath, only to stare in amazement at their employer's true gender. Katie was a femboi too! The toy she had been using had prepped her perfectly for the two and they both took positions on either side of the desk, Sasha with his cock ready to push into Katie's eager tailhole and Keiko already giving the bunny a good facefucking.
The three rumped like that for a while, spitroasting Katie over her own desk with her pathetic little pink cock flopping uselessly. After what felt like forever, the skunk and colt stopped and pulled out. Before Katie could whimper or beg theyput them back, Sasha was acting fast and pulled the bunny into his arms. Katie was now facing the gorgeous colt and felt Keiko's slender arms around reach from behind to help support her. When Katie felt the two broad cockheads press together at her tailhole, Katie nearly squealed with excitement... but they didn't push inside.
"Wh-What's wrong? P-Please give me the cum! I need it!" she whined and looked into Sasha's gorgeous amber eyes.
"Hire us," the colt ordered softly, never breaking eye contact.
"What...?"
"Tell us we got the job and we'll pump you full. We don't want you to use us and then toss us out. You get cock when we get hired."
There wasn't a moment of hesitation. Katie immediately kissed Sasha as passionately as she knew how, tongues dancing together before she pulled back enough to cry, "You're hired! <3"
They puhed in as one and Katie's mind went white as she came. THen she came again. And again. The feeling of those two big cocks pushing into her together drove Katie past her limits as her little cock splashed Sasha's chest again and again. Soon they were on the floor with katie sandwiched between them, pumping and thrusting until finally both skunk and colt reached their limit and let loose with a torrential flood of cum into the bunny. The potion Katie had given Sasha became apparent as the colt came longer and harder than he ever had before. When all was said and done, the three were lying next to each other with a very full bunny between them.
"H-Hey, your stomach's shrinking," Keiko muttered as she watched the swollen cum-filled tummy of Katie's shrinking and deflate little by little.
"I'm absorbing it," Katie said matter of factly. "It's one of the things I can do. Cum is a source of nutrition for me so... I really did need your cum. This is something you needed to see for yourself: long-term testing of potions left me with this and a couple other unique abilities. While processes have been changed there is still the risk of a permanent alteration to your body occuring if you work as a tester here. Are you both sure you want to pursue a carreer here knowing the risks?"
There as silence for a moment before both Sasha and keiko rolled over to put their arms around Katie. "There's no question," Sasha said softly and kissed Katie's cheek. "My original statement stands. I want to try new stuff and make new potions, no matter what happens to me."
"I think it'll be even more fun," Keiko giggled and the three hugged together for a goodly amount of time on the office floor. When Katie's stomach was narely back to its normal flatness, Keiko asked, "So, what were those other abilities?"
Katie smiled and blushed. "Well... these were from training and not potions but I can take so very big insertions and even still breathe with my throat full. Right, Sasha?  Didn't you like my blowjob? <3"
"Y-Yeah... <3"
"Anything else?" Keiko asked eagerly and Katie shivered once before taking their paws in each of hers and moving them down to feel between her legs. "No way..."
"Did you just...?"
Katie nodded. "That's the one other ability: I can swap gender at will." There was a moment of silence before both bois were scrambling to be the first at this new orifice before Katie stopped them and lay on top of the desk with legs spread wide to reveal her glistening bunny cunny.
"There's super-elastic Kei Corp condoms in my desk. First to get theirs on gets to be first. Ready... set... go. <3 <3 <3"
