“Hm... shit.” Lance murmured, stifling a groan. Ever since he came back, after being struck by that weird lightning bolt, Lance had been feeling odd. He felt flushed, bothered, and was barely getting any work done.
His whole body just felt hot all over, not to mention how tight his clothes felt. He loosened his tie and popped the collar open, fanning himself, before stealing a glance upwards. Was the a/c off, he pondered, before the visible green light confirmed his fears: it was indeed on.
“What the hell is going on...” Lance mumbled, turning back to the monitor.
Try as he might to focus on the report filling his screen, he couldn't, the heat seemingly gathering around his chest and groin. Looking down, he noticed a prominent bulge tenting his pants. It was starting to get unbearable, so he leaned back and took a peek around. Everyone was too busy on their own tasks, maybe he could...
“For fuck's sake...” Lance muttered before taking a bundle of tissues and popping his belt and pants open, releasing his manhood and gripping it.
As he jerked off and the euphoria took hold of his mind, he failed to notice the changes his body was undergoing: slowly but surely, his figure filled out and patches of fur began sprouting all over his body. His chest inflated into a generous bosom, popping open his shirt and sending buttons flying. His trousers burst at the seams as his lower body swelled, his legs fattening up and taking a more womanly shape.
Throughout this all, Lance remained oblivious to the metamorphosis, even as his shaft began to shrink and his balls were pulled inwards, instead trying hard to be as quiet as possible and not draw attention to himself.
Keyword, “try”.
He failed, of course, when his chair cracked and broke under the increasing weight, Lance felt his very meaty posterior impact the floor with a loud thud. And yet, he still carried on with his ministrations, a hint of confusion crossing his face as he struggled to find his shaft underneath the massive gut that covered his groin, pawing and reaching frantically.
Lance sat up, even as his face stretched into a muzzle and his ears migrated to the top of his head, vaguely aware that his member had vanished and in its place was a puffy and very wet vagina. On his, no, HER shoulders two lumps formed and swelled, quickly growing hair and developing identical features to Lance's canine face.
“N-need... release... mhm, s-so horny!” Lance's three heads groaned and panted intermittently, as she fondled her heavy bosom and pinched her sensitive nipples.
By now, folks were starting to notice the odd noises, musky smell and rising heat coming from Lance's cubicle, some even venturing out to take a peek inside. But before they could do so, out stepped a creature that stopped them dead in their tracks: standing at 7'3 feet, with a massively fat body covered in dark grey fur, a pair of humongous boobs and most striking of all, with three canine heads all giving them a sultry and hungry leer.
“Hey, guys” Lance's right head greeted, her mouth drooling, “do any of you feel like helping me with a teeny tiny little problem of mine?”
“You see, I've a bit of a conundrum to solve, and it's giving me a fair bit of difficulty” the left head explained, licking her lips and showing off her fangs.
Before any of her coworkers could say or do anything, Lance reached out and grabbed the nearest pair, bringing the struggling man, Roy, and the woman, Marcy, up to her right and left heads, respectively, and sloppily kissing them much to the confusion and fear of everyone present.
Lance's middle head grinned sultrily as she felt her two captives slowly cease their struggles and their figures became heavier in her meaty arms. “After all, we're a team here.” she said to the workers, “Like a pack. We gotta work together.”
Dropping Roy and Marcy, Lance chased after her fleeing coworkers, determined to spread her affliction. Despite her considerable bulk, she was fast, and was soon joined by the pair she had molested, their Cerberus transformations complete. They pinned, grabbed, fondled, licked and nibbled anyone they could grab, before moving on to the next victim, the previous one rapidly swelling and changing into a lustful pile of Cerberus flab.
It wasn't long until every man and woman on that floor was a naked, horny and quite fat Cerberus female, with Lance enjoying a rough threesome with Marcy and Roy, now her lovers, and she wasn't the only one. All around her she could hear a cacophony of pants, moans and howls of other Cerberuses, equally as engrossed as Lance was in relieving their carnal urges in every possible position and manner. Cubicles were broken, desks were turned and the floor was covered in debris and pools of sweat and cum.
As Lance snuggled up to Marcy and Roy, the trio basking in the afterglow, she had a thought, one shared with her two other heads.
“Guess I don't need to bother doing that stupid report anymore.” Lance's middle head chuckled.
“I know, right? We got bigger and sexier things to worry about!” guffawed her right head.
“Quite so, but for now, let's just savor the moment for a little while...” her left head agreed, nuzzling Marcy's right head, getting an appreciative giggle in return...
