A tooth too far

Second of my planned three TFTG stories. A regular male human goes looking for a good time, to make his dreams come true. However, he gets more than he bargains for with a specially engineered Sabertooth Tiger and fails to read the small print.


A young man in his mid twenties closed the door to his apartment, looking tired and worn down from work before slumping on the bed. This job had been running him ragged, and he wasn’t the type to go out a lot on days off. Pulling out a pamphlet from his pocket, his hands shook in both nerves and excitement. This weekend he was going to let his hair down and go wild.

A new type of agency had recently started up to cater for specific kinks called Hire a Hyper. Genetically modified animals that were created safe and humanely, and guaranteed to be a night you wouldn’t forget.

He phoned the number and nearly lost his voice when the operator said, ‘Hello, hire a hyper, what would be your pleasure?’

“Uh, um, er, y-yes can I er, see a list of your girls p-please?” he said, causing a playful chuckle from the other end.

‘Of course sir right away, I’m sending you our list on your phone now,’ she said as he got a message and tapped on the link with a trembling finger.

His eyes widened at the selection and variety, as well as how many extinct species there were. ‘We cater for every and all tastes as you can see, all you need to do is select one and then we can get around to billing and time,’ said the operator.

When he tapped on a likely looking choice, his eyes flew wide open at the bill. “Ffffu, I can’t afford this,” he said with a disappointed sigh. “Sorry to waste your time Miss,” he said, about to hang up.

‘Hold on, we can arrange for an alternate means of payment, one that requires no money from you. Just please pay close attention to the contract we send over with the id of a hyper of our selection.’

He was about to say no when another message buzzed, deciding to try the link. Upon seeing his prospective bed partner though, he found himself unable to resist the allure; rapidly skimming through the print before tapping to confirm.

‘Thank you Mr Paul, your hyper will come round to your apartment tomorrow at the given time. I hope you have a nice stay with us,’ she said with Paul shrugging at the odd phrasing.

The next day Paul could hardly focus on anything at home, he constantly glanced at the image on his phone. A large, six and a half foot sabre morph with a cute face, lovely hazel eyes, a body that would be a wet dream and what caught his eyes the most was her breasts. Those giant, massive, eclipsing breasts that hung down past her thighs. Paul had always had a thing for larger than life body proportions, but since leaving school his exact dates were just about nil. He was decent enough, could almost consider him cute. But he had no confidence and nothing that really stood him out from a crowd.

Flopping down to lay on his bed, he pulled his pants down and stroked him off to her image. Glancing down, he scowled at his length, again just average at four and a half inches. He snorted, well tonight all of his dreams would come true and she Had to pleasure him.

The rest of the day passed by with him passing time, trying not to focus on the evening's treat. Eventually his doorbell rang and looking at his phone, saw on the camera a giant, smiling sabre morph.

Instantly he had a full raging erection straining at his trousers. Shooting towards the door, he swept his hair back and opened the door.

“Hi, you must be Paul? My name is Samantha,” she said with a pleasing, gentle voice and accent.

Paul just stood there slack jawed, she was wearing a form hugging custom green dress that did nothing to hide her large hips or those colossal breasts.

“Um, h-hi I’m Pu-Paul,” he stuttered, only eliciting a soft giggle and tail swish from her, only making the poor man blush all the more.

“Aw well aren’t you a cute one, may I come in?” She said with a cute head tilt.

“Um yes, please do!” He said too enthusiastically, stepping to one side as the large cat woman bowed to avoid hitting her head on the frame.

She had to duck to duck to enter through the doorway before looking around and took her custom high heels off, letting her foot flex and the claws extend and retract. “It is nice playing dress-up but I do prefer the freedom of my feet. Guess that is one thing they could never engineer out of us, the freedom to let it all out,” she giggled at his blush.

Paul blushing only deepened as his eyes roamed over her, undressing her mentally before snapping to himself when she knelt down to peer into his face.

“S-sorry, you are just so beautiful,” he stammered, suddenly feeling bashful at having this feline beauty so close to him.

“Mmh well, no need to imagine. I am all yours Paul to do with as you please, just give the command,” she purred and picked him up as if he weighed nothing.

“So, where’s your bedroom in your cute abode?” she said as she looked around the small but neat house.

“Wh-I-in there,” Paul stammered, he was squished right up to her hyper chest, the softness and heat alone making his member throb in his pants but then her scent had him leaking pre already. ‘Fuck Paul this is going to be a pathetic night if you climax soon as she touches you. Come on, man up!’ He thought frantically to himself.

“S-so Sam um, how did they make an Extinct species into you?” he said in a way to distract himself from the sexy feline.

“Oh they bought a fossil of a sabertooth canine and extracted the DNA, they then fused that into an embryo and some other complex stuff, and here I am,” she said cheerfully.

He eventually instructed her to put him down and closed the curtains, shutting out the last of the setting sun’s light. Turning back around, Samantha was already taking her top layer of clothing off, leaving her in just a custom made white bra that did nothing to hide her breasts, each the size of his body and just a frilly pair of black panties covering her pussy up.

Paul stood there just about drooling before quickly and clumsily undressing himself until he was just in his boxers. His form though nothing special was at least well kept, trim and sporting a little muscle.

Jumping onto the queen sized bed, he was just about to lay his hands on her before she put up a cautioning hand.

“I just need to give you this last word or warning Mr Paul, once you lay your hands on me the contract is irreversible. You are aware of that aren’t you?” she said in that cute, soft voice of hers.

Now if Paul had any of his faculties about himself he would have picked up there was something going on here, but currently all the blood was heading elsewhere away from his brain.

He nodded eagerly and once she smiled and took her hand away, he was onto her. Whereas it was true he had a girlfriend once and slept with, this was the realisation of a fantasy come true. His hands hefted each breast, eyes widening at the sheer weight. “Ho-how much do these weigh?” He gasped as his hands sunk into the warm, soft flesh.

“Mmh about 8 kilos last time I checked,” she giggled with Paul's eyes widening.

His hands wandered to her back, feeling the smooth but taut sinew and muscle through her short fur coat. “You’d put bodybuilders to shame,” he mumbled.

“Well, it does take a bit of a toll on us, but thankfully we have genetics and they make sure we are all taken care of and treat well at the complex,” her talk turning into a quiet moan as Paul hefted, squeezed and rubbed, sampling the softness underneath the thin garment.

Paul was only half listening however, he was mesmerised by the sheer soft weight as he squeezed and groped her up, his cock slowly leaking pre inside his boxers, creating quite the wet spot.

“Here, how about you help me out of my bra and panties and I help you with your little friend?” she said in a husky tone, making him swallow audibly, only able to nod as he clumsily tried to unhook her bra. Managing that, he then eagerly whipped both her panties and bra clean off her, suddenly yelping as she had somehow taken his boxers off without him knowing and starting to skillfully stroke him, smearing his shaft with natural lube.

Yes, tonight was going to be a very good night indeed.

Turning his attention back to his prize, he actually drooled at the sight of her giant bare chest exposed, nipples fat and begging to be sucked the size of a cherry.

Just about ramming his face into her breast, he covered the fat begging nipple and sucked and squeezed, his tip running like a tap to her moans and the sensation as Smantha smeared pre all over his shaft. And it only got better as milk suddenly started filling his mouth.

Pausing, he looked up at her in an expression of worshipful wonderment, the Sabre actually seeming to blush under her fur as her tail gently batted against the sheets in her own building arousal.

“Don’t stop there hon, please drink all you like!” She moaned and arched, pressing her chest into his face, “it has been so long since someone drank from me!” She moaned out, her hands roaming and ruffling his short hair as she pressed his face into her soft tit.

He needed no encouragement as he gulped mouthful after mouthful of delicious cream, so rich and filling but the more he drank, the more he wanted and the more the fire of lust blazed inside him. He was in heaven and hoped this would never end.

Pulling his cock out from her grasp, he ground the slippery length over her mound, moaning around her abundant globe with Samantha’s moans matching his. He pulled off briefly to catch his breath, focussing on lining the tip of his shaft up with her wet, soft entrance before swapping breasts and at the same time, thrusted hard into her, the depths easily swallowing his length as Paul eagerly thrusted and drank her abundant milk, gently biting the nipple to make the sabertooth growl in pleasure and spray directly into his eager mouth.

His thrusts picked up as he found himself soon peaking and climaxing, pulling off as milk ran down his chin with a cry of pleasure, blasting his seed and painting her walls before slumping over her.

“Mmh that was lovely Paul,” Samantha purred, looking at him through half lidded eyes, “let me know when you want to go again okay?”

Needless to say, it didn’t take a lot of time before Paul was on her, filling her again, and again, drinking and fondling her, even using her breasts to fuck between her canyon cleavage and spray her in his seed.

They went like this again and again until Paul just simply passed out, not hearing her words, “I hope you have fun with us Paul,” she said softly.

*

Waking up to the smell of sausages and bacon cooking, Paul woke up with a groan. It felt like he had slept half the day away and when he looked at the clock, indeed it was just past twelve in the afternoon. “Nnh, oh man that was a good night. Can’t wait for another…what is going on?” he paused, hearing his voice. It sounded funny, lighter. And his body felt somehow different.

Raising a hand to his face, his eyes widened. His hand looked like a half formed version of Samantha’s, his hand bulking up with pads starting to form and his black, rough hairs turning smoother and softer, starting to form a true layer.

Whipping his phone out he turned the camera on, only to see his face starting to form feline features, holes forming on his face for where the whiskers would grow out and his ears were also changing shape.

A loud scream ripped from his throat and Smantha came running through with a look of alarm on her face. “Paul what is it?” She said, seemingly not seeing what was his distress.

“What is it?” He said quietly, “WHAT IS IT?” He screamed, on the verge of hysterics. “Look at me! Can’t you see what the situation is?”

“No I can’t, you said you had read all the contract and was aware. You were to be sent a specially engineered hyper and the cost for your night was to work the bill off for the month as one of us. My milk once drunk by a human starts to trigger their change into one like myself but to other hypers it has no effect.”

“What? No no, there was nothing there about this!” Paul said before pointing an accusing, shaking finger at her. “You…you and that bloody organisation tricked me! I’ll have you all taken to court for this!” He just about screamed.

Samantha’s caring demeanour changed into an annoyed scowl before pulling up her copy of the contract. There was small print but before he could accuse, she zoomed in. “You said you had read it all, it is here and the fact you didn’t think to zoom in and read the rest is Your fault,” she punctuated that by putting her hands on her hips, pretty much covered by her breasts, and stared at him as though challenging him.

“But, I-I can’t be a…girl! I’m a man, a human man!” He said, starting to shake as he realised more and more that there was no way out. It was in there, he only skimmed through and didn’t give a proper read, no court would accept his case.

“It is only for a month, and your work has been notified so you needn’t worry now, do you want to come downstairs before your teeth start popping out to be replaced by your new teeth and enjoy your food or not?” She said before leaving him to his thoughts.

It was five minutes before he came downstairs with a towel wrapped around his form as none of his clothes would now fit him. He could feel his face ache, so he didn’t have much time to enjoy the ability to eat as a human. He wolfed down the sausage, bacon and a good portion of eggs and bread, surprised at how much he was packing away.

“Your body needs the fuel so you will be hungry, and don’t worry, I also came prepared with some protein shakes whilst your new teeth grow in,” she said to a pretty much mute Paul.

And sure enough, it wasn’t long after he had finished when he was tonguing his teeth before one popped out, then the next followed by the rest onto the table, (along with a good amount of drool,) pushed out by his new forming teeth and large sabre fangs. “You’ll be able to eat in a few hours so don’t worry, the change is pretty rapid so maybe you will want to enjoy being a male for the next few hours? I am under contract to please you until tomorrow morning.”

She saw him just looking down at the table, staring blankly at his former human teeth, seeming lost and numb to the situation he had found himself in.

“Oh cheer up, it isn’t all that bad. You might even enjoy it, give it time,” she said, laying a large hand on a shoulder that was starting to bulk up a bit.

“Vut I vouldn’t ve male,” he said, unable to to pronounce his B’s owing to the missing teeth.

“It will only be for a month, and besides I saw how you were quite eager with my breasts; you’re starting to form some nice knockers yourself,” she said with a playful wink and pointed towards Paul’s chest.

Looking down, he could indeed feel a heat blossoming in his chest, and two soft, furry mounds were developing. “I-I have vreasts?” he said in confusion before gently giving them an experimental squeeze, his cock immediately hardening under the towel at the alien but pleasurable sensation

And so after Paul got cleaned up, they retired to his bedroom where Samantha gave him a skilled blowjob, surprisingly gentle despite the large sabres protruding from her muzzle. She told him to look at how he was changing, making him lift his head up only to see a light cover of fur forcing his groin, including his balls and shaft that right now, looked more felenoid in shape. Everything felt more heightened, sensitive as she got back to work, teasingly running her tongue over the length and tip, making him arch his hips whilst his hands busied themselves.

His chest was now about a D cup and grew at a constant, steady pace, gaining a cup every half hour. His body was slowly gaining more bulk, in both muscle and mass whilst his body became covered in a velvety black coat, the same in colour as his once human hair.

“I, nnh, haaaahh!” He cried out as he filled her muzzle up with his seed, arching and bucking his hips into her as he clutched tightly onto her own forming chest.

Things were starting to feel different below, there was a noticeable tugging sensation but that was overwhelmed as the changing human rode out his pleasure and desires before flopping back onto the sheets, basking in his afterglow.

“Mmhhh, starting to taste like a feline,” Samantha moaned as she licked the salty mess up, cleaning the oozing tip, jerking straight to attention again.

“Holy, wh-why does everything feel so sensitive?” he moaned out, every lick of her tongue had him spurting weakly into her muzzle.

“Mmh because the change heightens sensitivity, the closer you are to changing the more the nerves become inflamed. Meaning that I can get a reaction at just a simple,” she inched her padded finger to the head of his still oozing shaft, “touch,” she smiled playfully, stroking over the phallus head, causing him to grip the sheets as he weakly climaxed again, this time she let him make a mess of her, coating her gigantic breasts in the warm seed.

“Oh dear, looks like you’ve made a bit of a mess of me,” she said, smiling and licking his tangy juices from her before popping a large nipple into her muzzle, drinking her own milk.

The sight had Paul fully erect in seconds as he darted straight for the breast and started to suck, before pausing.

“It is better you drink as much of my milk as you can, the change will happen smoother that way,” Samantha said, gently rubbing the back of his head to encourage him like she would a cub before they were both drinking greedily of her creamy milk.

Afterwards Paul suggested they both shower and wash their juices off their bodies, but then he felt a sudden tugging sensation in his genitals, feeling like something was shifting deep within his core.

“Looks like your body is accelerating with the changes, want me to tease you as you become a female?” she smiled at his gasping moaning face.

“Y-yes please, this burning, I need something, haaaahhh!” He said, quickly becoming a she as his voice became more effeminate and lighter, his four inches starting to pull and melt away with his shrinking balls.

Her muzzle once again wrapped around his length, now just at four inches having already lost half an inch and gently sucked around. Bobbing her head in slow, deliberate motions, she felt and tasted as he came again, filling her muzzle with an increasingly lighter, female taste as his inches and orbs melted.

Reaching her hands above, she gently groped his breasts, feeling at how they were now well on their way to a Z cup and would soon be approaching her own impressive chest size.

Her thumbs traced over the now large nipples, feeling them pucker and almost throb to her touch.

As the final stages of the change kicked in, she pulled off and ran her tongue over the orbs, now the size of small olives as they pulled inside his new pussy, the foreskin having helped form the thickness and the retreating shaft forming a lovely large clitoris.

Gently and carefully, she pressed a finger into her pussy, thrusting it softly into the sodden, new folds and tongued her clit.

Lightning shot through Paul as he climaxed hard, his first female climax as his walls gripped hard around her finger, squirting into her muzzle before slumping on the sheets, panting hard in the afterglow.

“Holy…fff-uck!” she panted before seeming to just notice her own huge breasts, weighing heavily on her and hanging past her hips.

“So Paul, how did you enjoy your first experience of being a female?” Samantha purred as she crawled up the now black sabretooth, both their breasts nearly matching for size.

“Wow…just, amazing,” she panted before pausing then blushing under her fur at the husky tone in her new voice.

“Well, you will be in for a lot more of that with your month’s stay with us,” she said, gently squeezing and massaging one of Paul’s new huge breasts.

“Hey Smantha, do you…think I will be able to produce milk, like you do?” She said in a sleepy tone.

“Now that depends on your choice Paul, see how your stay as a Hyper for Hire goes then we will see,

Epilogue: One month later.

Paul, or Paulina as she had taken to calling herself now, had just visited her last client for the day. She boarded the private car to take her back to the office. Another satisfied client, another satisfying weekend.

Her mind played over what she and Samantha had talked about, they had become very…intimate as they got to know one another. She told Paulina that once the month was up, the effects of the milk would wear off, she would slowly revert back to her normal human form and she would be stuck like that for life. Once the effects wore off, the hormones wouldn’t affect her again as her body would build up a resistance to it.

She walked into their room after checking in with the office before going to their bedroom

“Paul, how did things go with your client?” she asked, dressed in just a loose fitting t-shirt and shorts.

“Well thanks, I think I have as many fans as you do at this point,” she giggled before feeling something in her chest. Looking down, her bra was a little slacker than it had been an hour ago.

“I see the effects are starting to wear off…soon you will be back to your normal human life,” Smantha said, her voice sounding a little choked up. “I guess this is”

“I’m going to stay,” Paulina said with a determined look, conviction in her voice before pulling Smantha on with her and without hesitation, lifted her top up to expose her massive, gorgeous breasts and latched onto a fat nipple. She sucked and squeezed, chugging the milk as if her life depended on it, feeling the hormones work almost instantly as her breasts surged back to their full size and milk began to fill them.

“A-are you sure about this, you can’t go back if you keep drinking from me like this you understand? You will be stuck like this forever!” Sam moaned as her sensitive nipple was nursed from.

“Yes,” Paulina gasped, milk dripping from her muzzle as she lifted her head up to look lovingly in her eyes. “I decided…why do I want to go back to my old human life? I was nothing, no one. Had no one and stuck in a mundane crappy job. I talked it through with my family and though they wonder if I am making the right choice by them, they do acknowledge I am much happier as this, in this line of work…with you,” she said the last part in a whisper.

Smantha pulled her up, angling their heads to avoid locking sabres as they kissed lovingly with each other before pulling away. “Then you had better drink up, drink well and drink from me every day for the week until you truly are one of us,” she moaned.

Paulina was all too happy to comply.

The End
