A group of scavengers discover an abandoned vault in the wastelands, only to discover more than a new home but a new life.


Virile Vault

"You gotta be kidding. A vault? And it hasn't been picked clean?" Big Jim scoffed as he finished his Nuka Cola, then breaking the bottle against the concrete wall behind him like he always did during the group's meager lunches. The four of them headed out into the wasteland hoping to find a place of their own, but for Big Jim it was mostly because he wasn't welcome back home and he couldn't imagine his compatriots being that much different. At 6'11' and 250 pounds of mostly muscle', Jim more than earned his nickname. His brown hair was kept cut short in an uneven buzzcut, and he had taken to wearing a leather jacket with one of the sleeves torn off in a bar room fight that got him and his friends banned from yet another settlement.

"This is one thing I wouldn't kid about," said Roach, prodding what was left of his ration with a fork. He dug a hastily hand-drawn map out of the pocket of his army surplus jacket, showing it off to Big Jim and the others. "See? Two hour's walk from here and it's fully stocked and still running. I scouted the whole place," Roach gestured like he was telling a ghost story, bringing his calloused hands together, then spreading them apart. "Not a soul around."

Roach was the survival expert of the group, priding himself on being exceptionally hard to kill, as evidenced by a winding, crooked scar he kept mostly hidden with his long, greasy black hair.

" The plan is, we break into that can and just hide out for a couple weeks, there's a really nasty dust storm coming this way. "If that catches us in the open wasteland, we're ghosts."

Sitting across from them was Murdoch, who was lounging on a bedroll reading an old, worn Chinese Spec Ops manual, as the group sneak he had already learned everything the book could teach him, it was purely for the illustrations he was looking it over again. He was wearing his usual attire of baggy pants and a hooded jacket, both a sandy tan in color. Beside him was Allan, the group hacker listening to old jazz songs on his pip-boy, a pip-boy he scavenged from a sacked vault before he met the others. They were an odd bunch, having only come together through by chance, which was another reason they were on the run. If someone in the wastes knew who you were and what you looked like, they knew what to shoot at.

Allan stood, casually slipping his hands into the pockets of his weathered vault jumpsuit. "Well, if you girls are ready, I'd like to have us moved into that vault by sundown."

Murdoch closed his manual and slipped it into his pack. "Sundown? You kidding? If that vault hasn't been cracked, there's no telling what kind of security that place has. We'll get mulched if there's turrets, none of us is wearing anything bulletproof man!" He said, his blue eyes squinted at the techie.

"Relax..." Allan said with a coy smile breaking across his oval face. "I'll handle the security. Those vaults all have the same system in their computers, and I've cracked it so many times you wouldn't believe.

Murdoch sighed through his crooked teeth and stood up, gathering up his bedroll and pack as Roach and Jim moved to follow suit, with Roah naturally taking his place in front of the pack. "Allen, you better be right about this." He turned to the survivalist, already leading them off the cracked soil path and on the trail outlined in their map, "And you, Roach... If you get us killed, I'm going to kick your ass."

Roach laughed, his boots kicking little eddies of dust with every step. "You're welcome in advance, then. Come on, the wind's picking up."

And so they went, making steady but cautious pace. Every so often, Roach would order them to take cover just in case, or Allen would check his pip boy map to make sure they hadn't been turned around at the last rock, fallen tree, or burned-out van. It was some two hours, a span of time that felt much longer thanks to Big Jim's insistence on singing along to Johnny Guitar, before they reached their goal. The four haggard men stood before a great, crooked edifice carved out of rock, contrived so that the entrance to the coveted vault was completely obscured by shadow to anyone who did not step inside the shallow little cavern.

Inside, they were greeted with the unmistakable sight of a vault door, marred slightly with rust but otherwise in remarkable condition. The men looked from one to the other, their faces turned from weary hope to excited joy when Allen's deft work at the door control's inner workings prompted the creaking round gear-shaped door to slide open with a thunderous creak of its aged machinery. "Hot damn!" Big Jim said with a grin, turning to high-five Allen with such enthusiasm that the hacker was left with a sore palm, "It'll be nothing but smooth sailin' from here, boys!" And so he rushed inside,with his compatriots close behind him. Inside the steel antechamber, the heard the door creak shut behind them, Roach turned to Allen and smiled knowingly. "Nice thinking, that door should keep us safe in here..." He ascended a small flight of metal stairs up to a gray and thoroughly unremarkable door and slid it open, taking a moment to admire the rare sight of a clean and completely orderly bunker. He turned to the hacker, who followed the other too in, "...By the way, Allen... Better make sure that door doesn't get stuck, a bunker you can't leave is just a crypt."

Allen nodded, and they made their way around the vault, partly to check for any traps left by the now-vanished residents and partly to survey what they have discovered. Their tour revealed bountiful stocks of medicine and water, advanced food replicators, and dormitories full of clean, warm beds.

"Incredible..." Roach said, having already stuffed the pockets of his jacket and jeans with whatever tech would fit in there, "Everything here... we're set for life, boys." He sat down next to Big Jim at a large, square table in the dining area, enjoying a celebratory feast of replicated liquor and snack cakes. Murdoch was part way through a funny anecdote about a one-legged deathclaw when he realized that Allen had not joined them, and indeed was nowhere to be seen.

"Where'd the nerd run off to?" Big Jim said through a mouthful of creme and vanilla cake, "He's missing out!"

"He'll turn up soon, Allen's probably just dicking around on a terminal. You know, sciency types are always so curious."

Then, the shrill howl of a siren split through the climate-controlled air of the vault, sending the lights into a spasm of flashing red. The shock of it was enough to make Roach spit out his vodka, coughing until his face was red. "The hell?! I though Allen disarmed the security?!"

"I did." Allen said, and the three men turned to look at the hacker, leaning on the door-frame to catch his breath. " There's an AI working this whole thing, I tried to crack it but it locked us in here... Until I figure out how to get to the override, we're staying here."

The mood of the room dimmed. Big Jim's jaw hung open for a second before he finally spoke: "You got us locked in?!"

"I didn't do anything, it switched on by itself." Allen said,running his fingers through his frazzled hair, " I'll try to get us out of this but I'll need you guys to follow me to the computer room, I think the security system is on the prowl again."

"Figures..." Murdoch sighed, "The first lucky break we ever get and this happens..." He was interrupted by a feminine, honey-sweet voice came from the loudspeaker system as the alarms died down. At first, it was a wordless tone, almost like a woman sighing after waking from a long, deep sleep, then it started speaking.

"Welcome to Vault M-013, young mothers! We thank you for signing up to take part in this wonderful experiment. When the surface is repopulated, civilization will thank you for your noble, heroic efforts."

Big Jim glanced over at the others, his square, lantern-jawed face wearing an expression of baffled fear. "Mothers? What the hell did we get ourselves into?!"

Allen rushed out of the dining room, with the others in tow as he made his way back downstairs to the computer room. "I don't know," He said, "And we're not sticking around long enough to find out!" The computer room was a sterile white place lined with big square terminals flashing colored lights of indeterminate meaning. Allen plugged his pip-boy into the console as the others crowded around him, trying to make some sense of the programming code and technical jargon that flashed across the screen as Allen frantically tried to find a backdoor into the AI's systems.

"C'mon Allen, you gotta pull through for us!" Roach said, peering over the hacker's shoulder.

"Something's up..." Allen said, taking a brief swallow from a bottle of water Murdoch handed him. "It's been too easy so far, either this is really shoddy security or... or-aaaAaagh!" And then the hacker was interrupted by a flashing surge of energy and a shower of yellow and pink sparks, sending him to the floor in a convulsive heap.

Big Jim grabbed Allen and pulled the hacker up, only to notice patches of soft black-and-white fur growing over his hands and neck. "Allen! You okay?"

Allen moaned, his eyes rolled back in his head. The black and white fur was spreading quickly, already covering his hands in a matter of seconds and moving up his face as his ears pulled out longer and longer.

"Something's wrong... I can't... I can't" Allen's mind was a foggy mess, gazing back at the monitor he could understand less and less of the code. Jim sat Allen down in a swivel-bottom typing chair while Roach got out his first aid kit.

"Hang in there, buddy. You're okay... you got me? You're gonna be okay!" He said to the hacker, almost coaching him. As he unzipped Allen's vault jumpsuit, Roach noticed that the hacker's body was changing quickly, with his waist narrowing and his hips plumping up as the fur spread over his body with the black fur coating his sides and arms while the white fur concentrated on his expanding belly.

Roach peeled Allen's jumpsuit down, trying to make some sense of what was happening to his friend. Allen wriggled and broke free of the survivalist's grip, dropping to the floor and stripping himself down to his increasingly ill-fitting boxers. The fur was completely covering him, his ears growing tall atop his head as his blonde hair reached flowing shoulder length. He kicked off his boots, revealing long, muscular paws with sharp toenails that had already shredded his gray socks. As Allen's belly plumped up, so did his chest. In a matter of seconds, he had developed a pair of perky, fuzzy breasts that went from petite A cups to full and milk-laden double Ds. The former-human opened his...now her mouth in a lusty moan as her face pushed foward into a cute little muzzle, her nose flattening into a little bunny nose as delicate whiskers sprouted from her upper lip.

"Oh god..." Murdoch said, approaching Allen, "Allen, what did it do to you?"

"I can't think straight..." Allen said, "...My... I can feel them inside me... I'm... gonna be a mommy." Allen continued wriggling around on the floor, pulling down her boxers to reveal both a fluffy little bunny tail as well as a puffy, moist and unmistakably feminine slit. This revelation sent the others into a panic, Jim looked to Murdoch and Murdoch to Roach.

"Mommy?! Oh that's what the AI meant! This is a mutagen experiment vault!" Murdoch yelled, wide-eyed. "It's turning us into hybrids of animals with strong breeding instincts!"

"What?!" Big Jim said, unable to believe what the rogue had said, though what he saw in Allen's changed body let him know there wasn't likely any other explanation.

"Jim..." Roach said, crouching down and taking Allen's fur-coated wrist. "Help... help her up, we have got to find a way out of here. Grab whatever you can, because we're finding somewhere else to crash!" Jim lifted the gravid rabbit woman to her feet and clumsily lead her out the door, rushing down the hall in search of something, anything that would facilitate their escape.

They had reached the atrium again, when the same motherly, sweet voice from before spoke again, freezing them in their place.

"Please," It insisted with the patient firmness only a mother could express. "You're in no condition to leave, no harm will come to you if you stay."

"We're not staying for nothing!" Big Jim shouted back, trying not to notice that Allen's litter was stirring visibly in her belly. "You can take whatever voodoo science you're working and shove it!"

The AI voice was silent for a moment, then responded: "I have no choice then, initiating security measures." This incited a yell of panic from Allen, who was still in a confused state of mind, as well as Jim. Murdoch raised his hand to quiet them.

""Easy... see that vent?" He pointed to a loose ventilation grate on the wall opposite to them, "That vent leads back around to the security room on this floor if the floor plans Allen has are any account. I'll crawl through, open the door locks and we can be out of here."

Roach looked over at him as he pulled his hood up and went over to the vent cover, unscrewing it from the wall and tossing it aside where it rattled on the metal floor. "Murdoch, we have to stick together, survival 101! This thing will have its way with us if we split up!"

Murdoch was already in the vent and crawling through it, "I'm not splitting up, you have my word!"

"But..."

Murdoch shouted back. "Roach, this is probably our only chance to get the door open! Do you trust me or not!" The ensuing silence from the survivalist was all Murdoch needed, he reached the other side of the cramped vent, cutting through the thin metal of the grate with his combat knife.

He pulled himself out, finding himself in what was very much a security room, with a single terminal, weapon and equipment lockers, and a small holding cell that he dearly hoped would not see use. He approached the computer, scrolling through the different options in search of the door controls. He had just about made progress when the monitor locked up, then displayed a lockout screen reading: "ACCESS DENIED, PLEASE THINK OF YOUR CHILDREN"

Murdoch yelled in anger at the monitor, he had come so close only for the damned Vault to pull the rug out from under him. He heard the soft humming of robotic joints moving above him and looked up, seeing a pair of arms extending from a slot in the ceiling, aiming what looked like to be a pair of plasma emitters at him. Before he could say or do anything, they blasted him with rays of pink and yellow.

On the other side, Roach heard the commotion and rushed over to the open vent, looking down into it with his flashlight. "Murdoch?!... Murdoch, say something if you're hurt!" Then, he heard the thump thump thump of Murdoch crawling back through the vent, though this time it was louder and the sneak's progress was quite a bit slower. Roach had seen a lot in his time in the wastes, but he wasn't prepared for what came back out of the vent. Murdoch squeezed himself out, panting and moaning in a voice rapidly becoming higher in pitch and more feminine, like Allen's had been.

What was most concerning was Murdoch's face, which was pulling forward into a long horse's snout as his sand-colored hair grew out into a silky mane, with matching velvety fur spreading over his ill-fitting clothing. His jacket hung open, revealing his undershirt straining to hold back a growing belly and a set of tits.

"No..." Big Jim said, still holding onto Allen. "Not Murdoch... What are we gonna do?" "I'm okay..." Murdoch moaned. "I just... need to.." He tried to stand, only to fall backwards onto his plumping rear, his jacket slipping down to reveal his fur-covered arms and shoulders. Allen rushed from Jim's side over to the changing rogue.

"You... Lemme like, help you!" The bunny girl said, tearing Murdoch's clothing off with her bunny paws as Murdoch squirmed in feeble resistance. As more and more of his body was exposed, the faster he seemed to change, with his belly growing heavy and even bigger than Allen's with a pair of healthy foals. With the bunny's help, she kicked her boots off to reveal a pair of equine hooves where her feet once were. Big Jim and Roach stepped back, there was nothing they could do anymore... they had to run.

They ran through the maze-like halls, their pace encumbered by fatigue as well as a growing sense of implacable doom. They were short of breath and sweating when they finally reached the door to the entry foyer, their hearts beating in their chests like drums as they saw the sliding automated door slide down torturously slowly.

Big Jim reached the door first, positioning himself beneath it and bracing his arms against it, gritting his teeth as he struggled to hold it open. "Roach..." He said,"You get out of here... I'll catch up to you if I can."

"No way..." Roach said between breathes. "You... I'm not leaving you behind... I got you into this and I'm getting you out!"

Big Jim's knees buckled under him as the door slid down a bit further, and to Roach's great horror he saw the muscular man's arms narrow, losing their muscle definition to a spreading feminine smoothness. A smoothness that came with black and tan fur... like a dog's fur.

"Jim! Look out!" Roach was too late as he cried out, the door slammed shut and Jim was thrown backwards, landing on his backside. From behind, Allen caught up to them, with a wide-hipped sandy brown horse woman with wide hips in tow, their tails swishing back and forth happily.

"Oh, don't run off!" The bunny said with a pout. "I'd be sad if my babies didn't... y'know... get to meet you!" The horse nodded in agreement, Roach looked upon them with their bright eyes sending a chill down his back. This was the end... there'd be no escape. He turned back to look at Jim, who was sitting cross-legged as he shrank and shrank, slimming down as the fur covered him and his ears grew long and pointed. His face surged forward into a pointed canine snout as a growl escape his plumping lips. His leather pants dipped around his expanding hips and narrowed waist, letting a thin, tapering tail come free, and the moment it did it started to wag... A wagging tail on a dog-woman. Specifically, a doberman.

Jim stripped down, revealing small, pert breasts and a growing baby belly.In seconds, her belly grew and grew as the former male stripped off her undershirt and briefs, revealing a puffy slit that showed that her masculinity had been eradicated entirely.

"Jim!" Roach cried out as he felt Allen and Murdoch grab him from behind.

"Sorry." The doberman woman replied in a meek, female voice. "I don't think I can just... leave and... raise my pups out there."

Roach went into a state of shock, helplessly letting the women escort him back to the atrium. His friends had been changed, not just in body but in mind, a twisted sort of feminine maternal instinct, made them unwilling to free themselves. As they let go of him and gently nudged him into a kneeling position, he looked up at the loudspeaker system mounted high up on the wall.

" This is for your own good," The AI said, the lack of malice in her voice making Roach's skin crawl, there was something basically wrong with something that was capable of doing all this with no ill intent or feeling.

"Fuck off!" Roach yelled back. "I'm not letting you change me!"

The AI was silent for a moment, then replied. "It's not your choice, and you'll need an attitude adjustment."

The others stepped away from Roach as a beam of pink and yellow struck him from above, Roach cried out in shock but it didn't hurt. There was an electrical tingle, but no pain.The tingling subsided, and he felt bloated, not around his stomach but a little farther down. His jacket and shirt felt tighter, painfully so. Roach let out a nervous whimper as he pressed in against his stomach with his hands and in a few short seconds, the bloated feeling kept getting worse and his shirt started to rip. Roach threw off his surplus jacket and peeled his tattered shirt off to find his lower stomach looking swollen in a way that was now very familiar to him, while a large pink circle of flesh pushed its way out, drooping down over the waist of his pants.

"Stop it..." Roach moaned. He was so shocked he didn't notice his nose pulling itself into a bigger, wider shape, turning black. He felt a sneeze coming on, he flinched in anticipation. He held it in... as long as he could...

He sneezed, and the force of it forced his outwards, flattening his big, black nose against his growing snout. The pink mound had gotten bigger, heavier. His paints felt tight around her waist so the white and black hairs sprouting on her chest went unnoticed. Roach pulled his pants off with some difficulty as his legs, especially the thighs and hips, had grown quite fat. His torso thickened as well, he could feel something kick in his belly... His baby kicked.

The spotted fur was making its way over his body and around the fledgling udder; it was already so thick Roach could no longer see his skin under it.

"Don't do this to mmmm-"Roach clasped his hand over his mouth. What almost came out wasn't his voice. It was the moo of a cow. He tried to stand but only fell back down onto his knees. She... no he wasn't used to her... his body being this... thick... this heavy with milk and child. His arms had thickened up. His neck had grown thicker and a little longer too. Then, she felt a jolt to his growing udder as it filled up with milk. Milk for her calf... Roach shook her.. His head. He couldn't let himself be changed... but the calf...

Roach's body quivered as his manhood shrunk into his plumping body, before vanishing entirely into a warm, moist and fertile womanhood. Her backside had filled out into a big, shapely posterior and a long swishy cow tail had finished pushing out from the base of her spine. Roach let out a moo, what was happening was no longer scary... rather pleasurable as her mind grew foggy. Her fingernails had grown thicker and darker, almost jet black. Her toes felt cramped and stiff like they were melding together. Her ears pushed themselves into long, loose things that flopped down below her hair.

She stood up slowly took a shaky step forward on her new hooves with the help of Allen and Jim.

"You're all due in a few weeks. Would you care to retired to your dormitory?" The AI said, Roach looked back up.

"Mmooo?"

"That's right, Rochelle. You, Alice, Jill, and Mandy are in no shape to be so active. You want to have lots of healthy babies don't you?

Rochelle the cow woman nodded, that made sense. A lot of sense actually. She wanted to be a mother, they all were linked by a newfound desire to raise families, large ones. Alice lead her with the others back to the women's dorm. "You could share milk with us!" The bunny said with a giggle as Rochelle's udder jiggled with every step. "Babies need lots of milk to grow up!"

"Yeah." Jill the doberman said, looking down at her own still-small breasts.

When they reached the dorm room, Mandy pushed past them and dropped herself onto the plush bed, letting out a whinny of relief. "I'm so tired..." The horsewoman said with a sigh. "I'll have to stay off my hooves for a while."

Jill curled up on her own bed, delicately stroking her full belly. "I hope I can be strong for my pups, they need a good mother in this world."

"I..." Alice opened her mouth to speak, but the bunny paused, her long ears folding back against her head. She played idly with her hair. "I forgot what I was gonna say but you're right. I'm gonna be the best bunny momma ever!"

Rochelle leaned back on her mattress, feeling her calf kick gently. "Easy, little one" She said. As they relaxed, the AI spoke up again. "Now that this phase of the experiment was a success, we can begin phase two...We'll make the wasteland safe for mothers again"

The mothers listened intently to the voice's plan, a feeling of pride spreading over them to take part in such a noble experiment.

"This vault will be your home for now, we'll need a lot more mothers to complete phase two but you can leave that to me.Your primary concern is your own offspring."

And the former scavengers nodded in agreement, they'd found more than a home but a purpose and a wholesome one at that. The world needed more mothers, and they would rise to the occasion.
