Defrosted Cavewoman, by DragonMasterX.

The cold surface of a metal bed jolted her awake. Her eyes had to adjust as the second they opened an excessive flash of light forced them shut again. The place smelled fresh yet stale, an overbearing scent reminding her of peppermint lingering in the air. Gradually, her green eyes opened and she took a long good look at her surroundings. The pristine white and grey room full of curious gadgets, tools and shapes she had never seen before made her anxiety rise. Everything was unfamiliar.

All she could remember was her name. It was Ellie. Ellie's memories were gone and what little she could recall were fuzzy images of her walking with several animals of different shapes and sizes. She remembered being huge and most animals being smaller than her save very few exceptions.

A familiar looking tube-shaped appendage curled up and she crossed her eyes to look down at it. The tip of that long extremity bent backwards, showing Ellie the nostrils of her own trunk. To the right and left, she saw long, curved tusks projecting ahead of her cheeks, coming out from the corners of her mouth. Light brown, orange-ish fur covered her body, with a generous, darker tuft decorating her collarbone. Ellie could also see the same shade of dark orange in the form of short hair bangs hanging just over her forehead.

Limbs weren't properly responding, her arms and legs held back by strong bindings. She could feel her fluffy tipped tail squished underneath her; paining her back once she became aware of it. Ellie realized how uncomfortable she was, but she realized one other, more important thing.

A woolly mammoth! That was what she was. But she wasn't huge right now. She didn't feel she was as huge as she was supposed to be. Her body felt weird, too. Her extremities were much thinner, lighter and more articulate than she remembered; but with the bindings tying her down to the metal bed, she couldn't test them. Ellie was convinced, however, that she should be seeing her flat feet outstretched above her instead of feeling five long curly things at the end of each arm.

Everything was weird; wrong. Ellie knew she was Ellie, but at the same time she was not Ellie. This conflict of thoughts and clashing memories combined into such a source of unrest that her mind began to race. "Nnghhaaaa...!" Cries out in frustration shot out of her mouth like fireworks, the strange woolly thrashing against her bindings with all of her might. Her struggle, as spirited as it was, however, turned out to be vain. "Where?!" she yelled out loud, smacking the sides of her bed with the tip of her fingers while kicking however much her bindings allowed her. "Why?!" she demanded to know.

Through privacy glass, several men in white coats observed Ellie. "She is speaking our language already."

"Not bad for her first wake."

"She is too violent right now. I doubt we will get anywhere if we attempt to communicate right now."

"Better let her expend her energy," the scientist closest to the privacy glass leaned in, "Though I am impressed the compression worked this well. Body mass has been reduced to roughly 47% of its original value. The procedure seems to have been a complete success."

"Indeed. The splicing of human DNA to this woolly mammoth's genome made compression an easy task. The instruments show her to be significantly denser than projections, however."

"The projections were ambitious. She can speak, and clearly at that. That should be enough for the board."

"Gentlemen... I think we're due for a bottle of expensive champagne. But first, contact that useless intern. We must arrange the interview with the ancient as soon as possible."

"We have time. She still needs conditioning... When she's calmed down," the scientist at the window said, pointing out Ellie was still struggling, albeit less energetically now. "Once she's worn out, we'll begin with trust exercises. We must prepare her for questioning."

Days went by. Ellie saw strange people coming and going, her fragmented memories letting her know these were humans. She remembered them differently for some reason. Ellie called out to them more than once, and to her relief it seemed like she got their attention, but they seemed to be choosing to ignore her. All they did was come close, offer her delicious food and water from time to time and something with a strange item in their hand before leaving again.

Slowly, the woolly felt her strength returning. But the bindings were too strong for her still. "Am I going to stay here forever...?" she thought to herself one day. Before she could reach the point of despair on that same day however, Ellie met someone.

That someone was dressed differently than the other humans. From the shoulders heading down, he was covered in blue, black, light blue and a little bit of dark brown. His expression was different from the people dressed in white. He looked at her and said 'Hi' each time they saw each other. From that day on, he was the one bringing her tasty snacks and drinks.

The young looking human introduced himself to Ellie as "Brian", getting her name in return. Brian told Ellie she had been asleep inside a big chunk of ice and the people in white had brought her here to treat her. That he worked for them and needed to ask her questions.

The people in white made Ellie nervous. But Brian was different. He was talking back to her and explaining things to her. "Big chunk of ice...?" the woolly continued to review the sentence in her head. Who were those other animals in her dreams...? They all appeared blurry, except for the one walking side by side with her. She felt at peace when she contemplated that one.

Brian snapped her back from her daydream, "I'll be back tomorrow too. Do you have any favorite snacks, Ellie? I could ask the guys to bring you more of those."

"The dark ones are really sweet. But I'd also like more fruit, please," Ellie replied, shaking a little. Her green eyes glanced left and right at her uncomfortable bindings.

"Oh right. Should be fine to tell you. Starting tomorrow, we'll be moving you to a different room," Brian said, taking the candy bar wrappings Ellie had pointed out off the table to remind himself of what she had asked for. "It'll have a table and a chair we can sit together at to talk. Would you like that?"

"It would be a lot more comfortable," Ellie replied, her cheeks lifting into a smile mostly hidden by her mammoth trunk. "Thank you."

"Thanks for talking to me, Ellie. You're helping us a great deal!" Brian grinned, giving her a small wave before leaving for the day.

From what little Ellie had learned, she understood she owed these people her life. But what life did she use to have? It didn't matter whether she was awake or dreaming, her memories were difficult to interpret. The fuzzy images did very little other than tell her she had been traveling with some companions. "How long did Brian say it's been since I've been asleep in ice...? Twenty thousand years?" she reviewed the information she had been given. It had been so long. She wondered if her companions were even around anymore. She was the only one left it seemed. "Maybe if I cooperate I can ask for help..."

The scientists were happy with how quick their intern had gained their subject's trust.

"Just getting her name in the first week has propelled the project by leaps and bounds, sir." One of the scientists in the observation room remarked.

"The strategy of generating contrast between our professional staff and the "friendly outsider" has been a success. All that is left is to begin the interviews."

"We're close, gentlemen," the project director announced in a voice louder than the others, "It won't be long before our window to the world of the past is open. This is history in the making! Offer the intern a better position if he manages to get our "Ellie" to divulge information in the coming days. We all need our incentives."

The next time Ellie woke up, the complex looking machines that had been surrounding her were all gone. Instead, she now was in a very different room. Instead of dull white and metallic grey, a colorful palette served as the backdrop for bright, flowery designs in a smaller yet cozier looking chamber. Despite still being strapped to a bed, Ellie felt inexplicably exuberant. The brighter colors such as red and orange were stimulating her while the softer ones like yellow and green brought tempering peace of mind. It occurred to her that other than Brian's clothes she had almost forgotten what colors were like. Her memories, after all, were still fuzzy and hard to interpret, fading between black and white constantly.

A door opened and in came a pair of the people in white. "Employers" and "Scientists", Brian had called them. The scientists came do their usual thing, using some strange looking devices which they pointed at her, waited for a sound and then left. This time however, Brian came in right after them. He was dressed in his usual getup, which brought certain comfort to Ellie. Her green eyes went over the sweets-loaded basket he was carrying in his arm. Her heart jumped at the idea of more chocolate and peanut butter candy bars.

"Hey Ellie. I got you some more of your favorites!" the short, dark-haired young man said. Ellie could feel her tail twitching under her, the tuft at the tip brushing along the table.

However, something odd happened this time. Before Brian made it to her, the pressure at her wrists and ankles began to soften until she felt it leave completely. With the inclination of the metal bed, she felt her body sliding pulled down by gravity. Surprised by the sudden freedom, Ellie moved her arms with surprising agility and gripped the sides of the bed to stop herself from dropping off.

Brian had been told ahead of time they were going to release Ellie for the first time with him in the new room. He put down the basket on the white table by two chairs before rushing to the anthropomorphic woolly's side. "Hey, are you okay?" he asked, scanning the lithe mammoth with concerned blue eyes. He sighed when he realized she was keeping herself still, relieved she seemed to be okay.

"That was exciting," Ellie sarcastically said, turning around on the table and dangling her legs out. She took a pause as her world seemed to spin for a moment, her perspective brusquely shifting after having held the same position for a week since she had first awoken. She realized too late the feeling in her legs felt weird to her. It was almost like her body had been expecting her to make the attempt to land on all four of her limbs, but another part of her saw it fit to get her to only use her feet. The conflict between what was nothing more than two different genetic memories made her begin carefully measuring each movement.

"Do you need help getting off the bed? You've been lying down for a while," Brian offered a hand, which Ellie curiously looked at. She let her instincts take over for the moment, feeling it right to take the human's helping hand. "There we go. Take it slow. I'm surprised you're even trying to walk this soon!"

Shimmying her hips in preparation, Ellie slid off the bed and her feet made contact with the strangely warm floor under them. She could feel the weight of her body on her legs now, standing upright to her six feet tall height. She only beat Brian by exactly one inch. "This feels much better already," the mammoth's trunk moved to the left, coiling around Brian's arm in a tug. "Thanks for the help."

At first, Brian tensed up feeling Ellie's trunk around his arm. But it actually felt like some sort of embrace instead of a grip. He wondered if she was expressing her gratitude. With intimidatingly large tusks like hers, it was hard to think of a mammoth using anything in their head other than to bowl over, pierce or smack around with. "Your English is getting really good too," he mentioned, "You were so quiet the first few days. I guess the lab guys really did their job well, huh?"

Slowly, Brian led Ellie by the hand to the table, where he showed her a seat at a white chair. He unwrapped the candy bars and told her to help herself to as many as she wanted. Ellie didn't wait long to begin digging in, and amidst energetic chewing she asked: "So what is it you want to know, Brian?"

"Well," Brian paused as he sat down across Ellie, getting caught off guard by her availability, "You know, the reason they brought you back was so that we could learn about the past. We humans didn't have as many tools to record History as we have now. And learning about what came before is useful, right?"

Shrugging, Ellie gave her interviewer a nod before helping herself to more candy.

"Like I told you a few days ago, woolly mammoths like you used to roam the land. Sometimes with humans of the past." With the mention of other woolly mammoths, Brian inadvertently elicited melancholic thoughts from Ellie's mind. She realized one of her companions had been another woolly mammoth. The silhouette in her fragmented memories was becoming clearer. "Since then, woollies haven't been around anymore. We thought we had lost your entire species, but these guys managed to bring you back."

"Hey Brian," Ellie interrupted, dragging a finger over her mouth to stick more chocolate on her tongue, "I feel like I should've asked this earlier. But I keep seeing myself walking with larger, stubbier feet instead of..."

"Hands," Brian helped, and then proceeded to answer: "Well Ellie, I'm not as smart as I think I am. But from what I understand, you're here looking the way you do because the same procedure that brought you back mixed your body with human gene..." the blank stare on the woolly told Brian to slow down, "...made you part human."

"So that's why I have um... fingers, and thumbs, and stuff, right?"

"Yeah! At least as far as I can tell, that's the reason. Looks like it was necessary to allow you to speak our language. The whole point of this is for me to be able to talk to you after all, haha!"

A small giggle left Ellie. She was still thinking back to that clearing image. It was still making her head hurt, but at the very least she now knew what a proper woolly mammoth looked like.

The unobtrusive cameras in the room fed the interview to the scientists compiling and sorting data. "Small talk is working. But I notice a divergence in brainwave patterns." One of the scientists said.

"How severe?" another asked.

"It's negligible at best, but this has never happened in the last week. Should we tell the director?"

"Just keep a close look on those readings. Compare them to earlier samples and get back to me." The supervisor leaned into a microphone before opening the communication channel directly to Brian. "Interviewer, continue talking about woolly mammoths. It seems to be stimulating her memory center. This could be the key to getting more data faster."

Tapping on his ear, Brian nodded to himself and opened with a new question: "Hey Ellie, I know you've told me you don't remember much, but do you mind if I ask what being a woolly mammoth was like?" he asked while tapping the button on his ear communicator again.

Ellie pondered the question, taking her time to swallow the candy in her mouth. "What was it like being a woolly mammoth?" she repeated out loud, glancing at her lithe yet fluffy body. More contradictions surfaced in her mind, reminding her how compact- how tiny she now was. "I think I used to tower over everybody. When I didn't look like this I mean. But for some reason I feel like I didn't enjoy my size for some time..."

"Because it was inconvenient?" Brian followed up. Ellie looked back at her interviewer and gave him a slow nod. "I would also be a bit worried if I was 11ft. tall. Humans don't grow that big so we don't make buildings with ceilings that high! But yeah, that's how big your kind used to be, Ellie."

"But..." she put a hand over her right tusk, trailing a couple of fingers over it as if doing a pensive stroke of the cheek, "...I think I met one as big as me. And then I started feeling really good about myself."

"You mean another woolly mammoth, Ellie?"

"I don't know. I mean, I think that was it. But it's hard to think about it..." Ellie held her head with another hand. "I'm feeling a little woozy."

"Huh. Do you want us to stop?" Brian raised his concern, glancing back at the candy, "You've been eating lots of candy, too. Don't you want more fruit?"

Eyeing a sliced watermelon on the basket, Ellie calmly grabbed it before cramming it whole in her mouth without thinking. Brian was left dumbfounded, but he quickly decided her mouth was bigger than it appeared; most of her face was covered by her thick trunk after all. "Thank you. I'm alright now."

Up above, the scientist monitoring Ellie's vitals was having his own case of being dumbstruck by the information he was seeing. "There's a substantial increase in inner temperature. The subject doesn't seem to be exhibiting any other abnormal symptoms, however."

The supervisor had been standing by the neural scanner, being briefed on their subject's gradual yet steady increase in brain activity. When he heard the news from vitals, he left for the other station. "What is going on? Will somebody give me a straight answer? Is the experiment in danger?"

"Sir," vitals responded, "The subject is physically fine. In fact, she seems to be better than ever. I don't think there's any danger of her condition worsening. However, coupled with the elevated brain activity..."

"...we're seeing neurotransmitters firing at highly unpredictable intervals," the scientist at the neural scanner said. "It's possible that the subject's returning memories are having physical effects. But before I can determine what those effects are..."

"Bigger," the supervisor mouthed off.

"Ah, right," the scanning scientist continued, "It might be possible to gain bigger accuracy if we just..."

"No, you fool," the supervisor barked, standing right next to the one-way glass of their observation cabin with a look of contemplation. "She is getting bigger."

Brian was so caught up in the interview with Ellie being so up-close that he didn't realize what was going on. It was subtle at first: The woolly was already pretty tall for a human female, so the first inches she added hardly made a difference. As their discussion went on, however, the changes became more and more pronounced.

It started with her chest. As a result of compression, Ellie's new body hadn't shown emphasis on her bust region. But that shortcoming was gradually turning into a thing of the past as her mammary glands began developing and pushing out.

Thanks to the generous tuft of fluff extending from the woolly's neck, Brian wasn't yet privy of what was going on. In a world with fragmented memories where she kept feeling weird new sensations every day, the tingling in her chest and a sudden sinking feeling from them didn't feel that alarming.

However, the chair the anthro woolly was sitting on was certainly feeling the constant additional weight. Ellie was sliding up against the back of the chair as she continued inching taller. Her feminine looking hips were starting to expand to even wider proportions, her thighs and buttocks plumping up in response to the extra space.

As questions and answers bounced between interviewer and interviewee, Ellie felt a rising amount of warmth coming from deep within. She was looking in Brian's direction, but her eyes weren't looking at him. She was seeing something else, someone else. She wasn't hearing him anymore, but listening to somebody else's voice. A harsh and stubborn voice; but a voice which also had an air of familiarity, dependability and attractive masculinity to it.

"Ellie." The voice said. "Come on Ellie!" it repeated, "We're going and that's final!" and after the harshness, a contrastingly softer: "It's you and me, Ellie."

With emotions like crashing waves in her heart, Ellie wasn't sure how to feel anymore. Her emotional vulnerability was causing her growth to accelerate and Brian couldn't ignore it any longer.

"Hey, Ellie?" Brian tried, but the interviewee seemed to be in a world of her own. His voice fell on deaf ears as he watched Ellie's body expand before his very eyes. "Are you guys seeing this? What do I do?" he asked via transceiver, but in his nervousness held the button so much he turned it off. Before Brian could look into his communicator though, a sharp grinding made him flinch.

The woolly was growing so large she was already towering over Brian by at least two feet. The increasing weight of her enlarging hips and hefty backside was starting to push back the chair, causing it to scratch its legs over the floor.

As her thoughts recalled her partner, she too began to remember more details about her life with him. With images ranging from saddening, to angering, to romantic, to loving and finally to lewdness, Ellie's loins began to warm up in response to arousal.

Bigger the woolly grew, the small bumps in her chest growing until furry mounds start poking out through her silky chest fur. Instinctively, a blushing Ellie brought her right hand up, experimenting with the expanding breast on the opposite side. She gave it a moan-eliciting grope, shivering all over as she felt her legs burning up. Her thighs plumped up with muscle and fat, attaining additional thickness which was mimicked by her inflating buttocks.

The intern couldn't believe his eyes. The shock was so great that even though his mind was screaming at him to escape the room, all he could do was stare at the moaning anthropomorphic mammoth. His eyes followed her free arm as it traced the curves of her relatively diminutive waist, heading all the way down to her overly proportional hips. Brian could see the chair legs buckling under Ellie's increasing weight with the sides of her extra thick behind starting to spill off her seat.

"Why can't I stop staring? This is dangerous. This is so dangerous and crazy," Brian told himself, his feet rapidly tapping the floor as his anxiety skyrocketed, "Woolly Mammoth brought back to life using human DNA. Mad scientist stuff. This? This is Twilight Zone BS!"

"Her size has increased by roughly 80%!" one of the scientists at the observatory informed.

The supervisor was on a direct line with the project director. "Sir, are you seeing this?"

"Risk of containment failure?" the director's voice quickly asked.

"Although steadily on the rise, her mass appears to be slowly increasing after the initial, explosive growth. According to our calculations, the effect might be slowing down."

"Remarkable... our subject's body has found a way to undo its compression. Going by that line of thinking, her growth should be stopping anytime soon."

"Sir?" the supervisor protested, "How can you be so sure...? Oh!"

There was a loud crash coming from the room downstairs. The poor chair which had been so far supporting Ellie had finally come to terms with the impossibility of the task. When one its four legs bent and finally came off, the others followed suit. The woolly's immense behind had already made the white chair invisible, but as her fattened up 'cheeks hit the floor she made any evidence of there being a chair in the room vanish.

"Mmm..." Ellie cooed in delight, ignoring the sudden brusque shift in position as she held her firm, round breasts over a palm, as if weighing their size. Each was now roughly the size of her own head without taking the trunk into account. They looked firm, capped with lovely, glossy, dark greyish nipples begging to be suckled. They had an unnaturally perky shape, as if held up by their own gravity, squeezing together into an inviting cleavage.

While the relatively undisturbed, amazon-sized Ellie checked herself out, Brian was working on sitting back up. When Ellie's chair broke, one of her huge legs accidentally kicked the table up and forced Brian's addled brain to make rapid judgment to avoid getting his head blown off by the flying furniture. He had shoved himself back a little too hard, skidding backwards on his chair which kept going, collapsing with him on it and causing him to land on the ground with a rough tumble. He felt fine, but one glance at that that female woolly's killer curves glued his ass down and robbed him of words again.

Ellie had grown even larger, and Brian understood the scope of her new height once she began to stand back up. She had to be almost twice Brian's size, utterly looming over him. That exaggerated, curvaceous figure was doing things to Brian that he didn't know he could've wanted. Green eyes charged full of lust, bosoms like ripe fruit begging to be taken, that curved in waist and the flaring out hips. But what truly stuck out were those massive hips. Ellie's behind had inflated to absurd proportions and Brian could swear he could hear the flesh of each glut smacking together with every obscene jiggle.

"Sir, we're ready to breach. All tranquilizer rounds loaded just as specified," the security leader was being accompanied by five others in his unit. All the armed guards were right in front of the door to the interview chamber, "On your order."

"Stand down, captain," the supervisor said.

"Sir?"

"The subject isn't growing any bigger. She seems to have stopped. And what is about to happen is going to provide us with a wealth of unexpectedly valuable data. I repeat, stand down."

The captain exchanged looks with his lieutenant, but one glance inside through the one way glass windows told the summoned squad why they had been stopped after getting called only minutes ago. Something wild, something not found in any biology textbooks was about to happen inside of that room.

Ellie felt right at home in her position. Once the fog had left her eyes, she saw a much smaller Brian sitting spread-legged before her. One glance at his groin told her he was hot and bothered much like she was. Her human impulses and latent instincts were mixing with her primitive ones, letting Ellie understand just how turned on her interviewer was. "Whatever just happened to me made me feel so good. I'd forgotten how good I could actually feel..." the woolly thought to herself, tantalizingly dragging a finger over her left tusk all over to the tip before dragging the digit down and circling back to one of her massive breasts. "Who knew these human-like breasts could feel so good? He seems to like them..." she began to smile as she cast a hungry gaze over Brian.

"Ellie...?" the young man trembled, intimidated by the buxom amazon looming over him. He dragged himself away as she began to step forwards, her jiggling curves accentuated by the natural sashay of her hips. She was walking like a total seductress whereas only hours ago she had been taking her first few steps. "What's going on with you?"

Ellie couldn't answer his question had she wanted to. Distant memories of the past had finally resurfaced, and albeit the details were still unreliable at best, the heat and passion of lovemaking had left a strong imprint in her mind. Perhaps her expansion, which had physically wreaked havoc with her hormones, had to do with it, but she was feeling bold. A lot less interested in finding about herself and more interested in taking care of the fire burning her loins, Ellie continued her seductive approach towards Brian.

"Ellie, puh-please, talk to me," Brian finally found the strength in his legs to stand back up, but he still was slowly backing away so she caught up to him easily. Her prodigious bust soon was like an overhang casting a shadow over him, further cementing the size difference now that he couldn't even see her eyes. "This is unusual, I'm not used to you ummppphh..." the interviewer's words became muffled as Ellie leaned down, putting her hands on his shoulders and her hefty rack on his face. Brian's head became swallowed by her deep cleavage. He didn't dare move a muscle as he felt her trunk slithering down his back, curling around his waist and rubbing over his stomach.

The mammoth was certainly feeling flirty. Now that she was big, she could effectively throw her weight around and it was easy taking charge. She displayed her affection by patting him down with her trunk, but was quick on the uptake with her potential mate's likes as well. "Hush, Brian. Enjoy yourself. I plan on doing the same," Ellie cooed, overtaken by her worsening arousal. She was fully aware of how he had been staring at her massive tits, so she made sure to rub her chest all over his face while she felt his body with her hands and trunk.

Brian had a sturdy, if small-ish human frame. Ellie could immediately tell she would have to be careful now that she was almost more than twice his size. She was moist and eager, her sex aching for action after so many eons. She was like a primordial cavewoman in the shape of a sexy woolly mammoth, wanting nothing more than to break her man's pelvis. But Ellie wanted to be a little more considerate than that.

Before he knew it, Brian was on the ground again. Ellie easily pushed him over, forcing him to fall flat against his back. The heft of her breasts on his face had been making him go blue; he had been having trouble breathing with so much fluff and mammary flesh in the way. Thankfully however, the shift in position allowed Brian's lungs reprieve, but soon his lower body was threatened when Ellie sat down on his legs. He felt an overwhelming amount of softness over his quads, knees and most of his lower legs as that fat mammoth ass rested on him. Fortunately for Brian, the way Ellie had decided to straddle him her knees were pressing down against the floor to his sides, so he hadn't been carelessly pinned down.

Many questions floated in his head. Chief ones being why his employers had yet to storm in to get him out of his predicament, and how had he not been utterly and physically crushed yet. Ellie was being considerate, he had to guess. The way she was straddling him again had those titanic boobs hanging above him, her abdomen looming over him. All he could see of her head were those mighty tusks unnerving him and that thick trunk stretching downwards, coiling around his waist and tightly hugging him. In a paradoxical manner of thinking, Brian felt like there was no safer place to be. Perhaps he didn't want to get rescued.

"I'm so horny..." Ellie grunted, fighting her instincts to start humping as she eagerly explored her new lover. She could feel her cunt dripping with juice, but she also knew she needed more than just her own sex to feel good with her partner. She decided to tease him more, her hands groping her breasts to give him a show while her trunk continued to explore him. As she breathed in through its nostrils, her trunk inevitably found a source of masculine musk under the human's shirt. She investigated.

Enthralled by the show above him, Brian didn't pay much attention to the tip of Ellie's trunk acting like a gripper, pulling his shirt and pants away until she had effectively freed his member. With the scent growing stronger the more his dick was exposed, Ellie had no problem adapting to the conundrum of finding her inter-species partner's own sex.

Brian's penis was rigid already, and Ellie could remember how good playing with it could feel for both she and her partner. The trunk encircled the seven inch human shaft like a snake coiling around its prey, giving it a squeeze which elicited a groan from the interviewer. "Uhh-Eh-Ellie... that feels... gew-good..." his stammers were full of confusion but also arousal.

The young man had been entertaining the thought that he might have been asleep, overworked by all of his recent efforts with the revived woolly anthro and his sexually charged brain had decided to give him a particularly raunchy wet dream. Spurred on by the growing horniness he felt, Brian convinced himself. The only way these events made sense to him was if it all was a dream. That swollen mammoth vulva drooling juices over his pants was only further evidence that he should go along with it. "Ellie, fuck, you're making me feel so good...!"

Proud of herself, Ellie gave him a few more pumps. Regardless of her intentions to have some foreplay however, the yearning for coitus was simply too much for her. She liberated her breasts which rocked and jiggled against each other and put her hands down. Her palms slammed down beside a widely grinning Brian's head. He was barely flinching now, even at the cracks on the tiled floor.

Ellie's trunk released Brian's turgid flesh. She could feel wet pre-seminal fluid running down her trunk and before it reached down to her nostrils she curled the appendage and sank it inside of her mouth. She sucked the shaft of her trunk, thoroughly cleaning herself before coiling it back out with a coat of saliva. The taste of pre tickled at her memories further and her snatch begged her to do the deed already.

"Brace yourself, Brian!" Ellie fired her one and only warning, scooting up while barely lifting her hips off the young man. Brian seemed cocky; relaxing with his arms behind his head as he expected this was where his dream got interesting.

"Oh fuck...!" the intern yelped as he felt himself slide into that yearning pussy. The amazon pierced her womanhood with his shaft at once, spreading her entrance with his adequate intruder. Brian clenched his eyes shut with Ellie, their shared pleasure a result of their sudden oneness. "Yuh-yeah... oh fuck yeah this is tight. This feels so real! Do it. Fuck me!"

Made desperate by the memories of breeding with her past partner, Ellie replicated movements she didn't know she knew. Her human genes complemented basic instincts, allowing the horny woolly to deliver eager humping while gliding her fat ass cheeks over the human's legs and hips. "This is... ahh... this is just... nnghh... what I've been wanting...! It's been so long...!"

Brian couldn't talk anymore, only moan as his cock was getting milked by that hot mammoth pussy. He barely had any agency and now understood just how coincidentally accurate he had been in telling her to fuck him. The human had no chance against that cavewoman, she was humping his brains out whether he wanted her to or not. And there was a strangely attractive if slightly suffocating appeal to it.

He ignored the pain of his back sliding to and fro against the floor, Ellie's cowgirl thrusts so powerful that she wasn't merely humping his hips, but his whole body with her unbelievable strength. His eyes became glued to her bouncing tits, which she grabbed and squeezed on occasion just for him. "Yeah, squeeze those tits. Damn they're so big! I didn't think fucking a dream mammoth would feel this good. Fuck yeah...!" he moaned. "More! I'm so close already...!"

And Ellie was close too. At first, squeezing her breasts had been something she had been engaging in simply to satisfy her partner, but the more she played with those huge mammaries the more she grew fond of their softness and how pleasurable attention to her nipples was. She bounced her immense 11ft. tall body up and down, hearing noisy, wet slaps coming from down below. She was going to get that human's seed inside of herself; Ellie couldn't believe just how much she needed it inside of her. She was beginning to burn up again. Release was close for them both...!

And then they came, together. Brian shot his load inside of her vaginal tunnel, but a large portion of his semen was expulsed by Ellie's concomitant squirting, juices pushing out so hard the vaginal contractions sent spooge dribbling out between the crevice of her pussy and his dick.

"Nnnghhaaaa...!" Brian yelled as he creamed himself inside of Ellie, his body spent after the intense sexual encounter. Without the weight of thinking of the reality of him having just been fucked by a revived animal from 20,000 years ago, he gladly allowed his consciousness to fade, falling contentedly asleep under his fantastic lover.

"Ahhhhh...!" screamed a sex-crazed Ellie, experiencing her first orgasm in ages. She felt like something had exploded inside of her, and she was sure that Brian's small human dick hadn't ejaculated that hard. She was still warming up, and a familiar tingling was suddenly taking over. Instead of being distracted by her past memories this time, Ellie could appreciate the sensation in full.

She could feel her curves expanding alongside the rest of her. Her muscles tightened for a moment before distending in an involuntarily flex as she felt herself suddenly growing again. Only this time she was enlarging significantly faster than before. Surging upwards, the woolly hit her head on the ceiling while still kneeling, which forced her to bend over and finish covering the unconscious Brian under her immense rack.

"Whu-what is this strange sensation?" she thought with a pleasant shiver while doing her best to lift her chest off the small human to avoid crushing him under the weight of her breasts. "This is so wrong. I feel like I'm much bigger than I should be right now! And yet... it feels so right! It feels so good. I could barely feel it before I got all hot and bothered, but now..." her thoughts were interrupted as she let out a squeak when something sharp hit her from behind.

When she glanced back, Ellie's view was mostly blocked by the flare of her monstrously large hips. But over the contour of her rump to the far right she could see the outcropping of a cylindrical object.

"Direct hit, captain!" came a voice from behind Ellie, which prompted her to shift and extend her glance to the entrance of the room. She counted five heavily bundled up humans, all of them holding a kind of tool that looked like an overly detailed stick. "The target is... uh... wobbling?"

"She's three times the size of a human, the tranq dosage isn't working!"

"Fire again, second shot!" the security team leader ordered, and all five rifles fired again. They heard a confused Ellie squeak out in surprise as the needles prickled her on her excessively wide back target. Impact from the projectiles did very little other than surprise the woolly, that extremely thick bubble wobbling dangerously as she shook her hips as if she had been stung by a group of large mosquitoes.

"What are you doing?" Ellie asked, causing the five humans to take a wary step backwards. She frowned, annoyed at the prickle at her tremendous backside. She was about to reach back to remove whatever they had struck her with, but her body began to rumble. "Oooh...! Ooomph... mmnngh...!" she shook and jiggled, elbows cracking the tiled floor as she began to stretch in all directions.

The security team was caught unawares as Ellie's feet suddenly shot towards them, her legs sliding across the floor with blinding speed as instead of becoming knocked out by the drug specifically tailored to tranquilize her, the already giant mammoth became even larger. "Look out...!" the guards tried diving out of the way, narrowly escaping being razed off the ground by the giantess' rapidly advancing feet.

Her body swelling uncontrollably, Ellie could only moan as she felt her breasts inflate even larger. She could feel her cleavage overtaking the sleeping Brian, who was inadvertently captured in-between her boobs as she became huge enough to hit the ceiling with her back. When she felt her feet hit the walls to her south, Ellie involuntarily spread her legs to take advantage of the extra horizontal space.

However, she kept growing, bigger and bigger, and her hips weren't excepted. Her ass ended up growing against the wall and its fattening gluts pressed up against the shocked guards, pinning the team between the wall and the soft tautness of her spherical buttocks.

"We're trapped!" one of the soldiers lamented themselves. "Why is she still growing?"

Another guard yelled: "Why didn't the tranquilizers work, damnit?!"

"And why is this so soft and comfy?!" a third couldn't help but observe.

Ellie wanted some answers herself, but her brain was too overloaded with her senses being stimulated by her rampant expansion for her to engage in critical thinking. The bigger she got, she more sensitive her woolly skin became. Her billowing curves were awfully receptive of the way they squished around surfaces and the squirming guards who had failed to escape her.

But above all, Ellie couldn't ignore that unnatural tingling sensation welling up from her very core and extending to the tips of her tusks, ears and digits. Ellie could feel power coursing through even an individual hair strand on her head. "This definitely... ahhh..." her moans grew in volume as she rapidly filled the small room out with her increasingly larger frame. Much like when she was unbearably horny, she was now getting insatiably hooked into the feeling of growing bigger. "...feels good. So strange, but so good, I feel like I'm going to... going to..."

"...explode!" the supervisor yelled in the cabin as he watched the madness unfold, "I'm going to explode if nobody tells me what's going on with the subject! Our security team was equipped with twice the necessary formula to knock her out for an entire day. You!" he pointed at one of the nervous lab coats.

"We thought she had been somehow fighting our genetically induced compression, sir!" the scientist in question tried explaining, "But this goes beyond the amount of mass we stripped her of with the treatment. We thought cellular growth had slowed down after the initial spurt but now..."

"Now what?!" the supervisor demanded with eyes so piercing he could have punched a hole in one of the computational servers. But the supervisor hardly got a response from his frightened team. Initially, he thought his stress had gotten the better of him and he was fulminating the already pressured scientists, but one look at where their eyes were looking told him his fury was the least of their concerns. Slowly turning around, he saw a pair of massive green eyes looming over them through the one-way glass window.

The supervisor knew Ellie couldn't see them, but that didn't matter when her trunk, now thicker than any of them, was pressed up against the glass. Those green eyes closed and they could hear her whimpering through the mics as her face smooshed up against glass. Cracks webbing out alongside the cabin's windows finally made them all realize that Ellie was truly out of their control now.

"Eeep... uhh-eeh-evacuate. Evacuate the building immediately!" the supervisor managed to say, and one of the scientists rang the emergency bell right on time. As the alarm system started blaring, glass shattered and Ellie's face crashed into the cabin. Her tusks punched holes in the concrete wall, emerging from the sides of the window to the noise of shorting circuitry.

Ellie was shifting constantly now. Running out of space meant her body was starting to grow into neighboring areas. After bumping her face into what seemed to be an outcropping at the highest corner of the room, she was shocked with what little resistance it offered with her head going clean through.

The weight of the giantess' mammaries became so great the walls under didn't hold up very long, either. Those fluffy wrecking balls exploded out into the hallways, making a couple more scientists who had been attempting their escape join Brian in Ellie's cleavage. Behind her, the walls were also crushed by her ever expanding ass, each delightfully buxom glut now twice the size of her own torso. In an attempt to straighten her involuntarily split legs up, Ellie clamped her lower limbs together in a scissoring motion, sweeping a couple of chunks of the building while snagging more people in process of evacuation with her thick wool. As she grew ever larger however, this move made her feet rapidly crash past the walls opposite to the hallway going into the room she had filled up.

Blaring alarms meant very little to certain personages in those laboratories. The lead scientist in charge of studying the extinct saber-toothed squirrels was hardly paying attention to the evacuation order. Its pristine skeletal specimen had been perfectly preserved in the act of reaching out for a now fossilized acorn caught in the same block of conserved ice.

Despite the cold temperature necessary for conservation, the lead scientist was hugging that large block of ice like his life depended on it. "I won't leave my precious! What's with all the fuss about the woolly mammoth anyway?! Saber-toothed squirrels are superior, the grant should have gone to me, ME!"

"Yes professor, whatever you say," one of the zealous man's undergrad students found himself pulling at the obstinate old researcher, "But right now we have to LEAVE! If we don't we'll be..." But before the kid managed to finish his sentence, the wall next to the lab's entrance broke apart with a gigantic foot crashing in and bowling over all counters and equipment. The fluffy, woolly leg attached to it was fast approaching, wide enough to take up a good chunk of the room. "Gah! It's here already! We're still in the first floor, let's jump out the window!"

"I'm not leaving my darling...!" the saber-tooth squirrel scientist cried out before he got yanked by his student. In his arms was a ripped chunk of ice holding the fossilized acorn. As the professor and student jumped out one of the lab's windows, the ball of that gargantuan foot finally hit the ceiling. The resulting tremors knocked sent such strong vibrations everything was further destroyed inside the lab.

And the large chunk of ice broke off one more time, this time the saber-tooth squirrel's frozen jaw bones falling down. The lab was then quickly overrun by the giantess' foot and ankle.

The building had erupted into pure chaos. Try as they might, most of the scientists trying to escape the giantess' rampant growth couldn't keep up with her. Ellie was growing in powerful spurts and all of her body seemed insistent on invading every horizontal sector in the labs. Already passing 30ft. tall, her back crashed past the first floor, currently working on filling up the second. Her victims were fortunate her hefty form was covered in voluminous, wool which gently trapped them without worry for being hopelessly crushed.

Even Ellie's insanely developed curves had crevices that worked to scoop people who couldn't get out of the way in time. She could feel their squirming bodies struggle against her rumbling, ever swelling form. By herself, Ellie was equal parts concerned and overtaken by her continuous growth. The magnified sensation of uninterrupted enlargement brought her pleasure which was tempered by the reality of her spatial constraints. Her surroundings were failing spectacularly at containing her, but the feeling of her hands, arms and elbows carelessly bowling down walls while her legs and knees slid across the ground made her consider how truly massive she was becoming. And yet for all of her concerns, Ellie didn't want to hold her moans of lewd bliss back.

The truth was Ellie had come to adore the growing feeling inside of her. Ceilings uselessly crumbling against her back and extra thick behind made her curls her toes in excitement. Her excitement redoubled when her feet wiggled outside with fresh air stroking her naked tootsies. The gigantic woolly clenched her teeth, wiggling and smashing her hips into several walls due to her uncontainable earnest.

More scientists fell from the second floor onto those perky buttocks, sliding into her crack with no less than half a dozen other 'victims' currently treated to the incredible softness of those wobbling ass cheeks. A similar number of people currently swam through Ellie's tuft of chest fur, either lost in that silky jungle or otherwise immobilized in-between her sloshing knockers. They had all been evacuated into the comfort of her supersized woolliness.

And the process was only making things worse for the three and half story building. Ellie was rapidly running out of space to grow into as her wiggling feet outside evidenced. Fissures extended all around the surface of the edification, its structure beginning to fail. Her shoulders soon dug holes into the concrete of the rooftop, her tusks lifting an entire wing as they hooked through the walls and also came outside. Those standing clear of the building could see her cleavage thanks to the chunk of building being suspended several feet above the ground floor.

"Bigger..." Ellie murmured as she tilted her head back, her tongue lolling out. Her cheeks were just as red as when she had felt that overpowering need to breed earlier. But now it was more than just her pussy aching for a stuffing; the female mammoth needed this expanding sensation to bring her over the edge. And she knew for that to happen the only way was up!

As if talking to her own body, Ellie repeated: "Bigger...!" in monotonous yearning, "Bigger, bigger, bigger...!"

And bigger she grew. Windows exploded with raining crystal, bricks falling off as walls continued to crumble around the swelling creature's bulk. It wasn't long before the labs fell apart, debris rolling off Ellie's impervious form as she swelled ever greater. "Yes....!" She yelled out with need, excited for more. The flared up greatly and soon demolished the entire building with her growth.

The people witnessing this unusual spectacle were treated to a major dust cloud kicking up when the inner demolition job concluded. And when the dust settled, they could all see the once proud research installations had been replaced with the world's largest mammoth. At over 60ft. tall, Ellie was more than half the size of the biggest mammal in the planet: The Antarctic blue whale.

"Mmm... what a rush!" Ellie panted with half-lidded eyes, the glint of afterglow in those emeralds. She gently wrapped one of her head-dwarfing breasts with her trunk, careful to not crush any of her little fans trapped in her cleavage or her chest fur. She gave herself a tantalizing squeeze while trailing a finger over her curvy waist and up the amazing well of her tremendous hips.

Onlookers watched with disbelief as the giantess seductively laid on her side. When her finger reached her hip, the saw her smack her fat ass with a loud spank, her thick ass cheeks wobbling so much they engaged in meaty clapping. Her tail snapped up into the air as she played with her eager labia with a couple of fingers; she was still drooling with desire down there.

By a stroke of fortune, other than minor injuries, no serious bodily harm had come to those who had failed in evacuating the building during that commotion. And although Ellie's growth seemed to have grinded to a halt, her sexually hungry eyes said it all: that woolly giantess wasn't done. "Bring me your biggest male," she demanded.

If the ice age had made woollies extinct, then it was her duty to bring them back, after all.

The End.
