Exhausted, Cory lay panting on the medical bed. His body was completely worn out from hours of effort. Though the fog of mental fatigue he considered how his life had come to this. How he had found himself in this place; possessed of female genitals and having done something with them that no male human ever had. He had just given birth... to five babies... and they were wolf pups!
The father was his current owner, a crazy wolf scientist he had heard others call “Doctor Black”, but he was told to refer to him as “Master Mace”. Somewhere in his mind he still grasped at the idea that this was all just a dream, that the last months had all been a dream...

“And here we can see the new pups. The genetic tests just recently came back confirming that these are 100% feral wolf. We’re planning to captive-raise this batch and then try and set up a more progressive breeding program. In time we can even potentially expand to other, more critically endangered species.”
“Amazing Dr. Black!” exclaimed the bunny-woman who bounced alongside him, “And all with one human male as the template! All I wonder about is how you got the wolf DNA.”
“Archived donors,” Mace replied coolly, “We ended up using a lot of samples to get it to take. Fortunately this means we can use any of our own reproductive material, combine it with humans, and get a feral creature out of the deal. It has to do with my Anthropodetranscriptase enzymes, a labor of many years you understand.”
“And the genital deformation?” she continued.
“A side-effect of the genetic compatibility serum. I still need a lot of future experimentation, but I’m certain once this process is perfected that we can work to restore the ecological balances of old.
Mace walked along with his interviewing student, Mellany, pointing out portions of the minutia behind his research. As a biotechnology student she was brilliant, full of intuition and promise, but seeing her hairless, wasted form pulled at his heartstrings. For a moment he wondered if restoring rare species had been the right direction. Perhaps had he gotten a different start, he could have been the one to cure cancer.
“And what is the next step of your experimentation?” asked the young student, her energy and enthusiasm belying her condition, “Will you continue with wolves or will you expand to other species?”
Mace snapped out of his worries. This crazy young bunny, pink as the human he had used to father his latest branch of science, was more excited for his research than worried about herself. The realization filled him with determination... and no small amount of lustful thoughts. After a minute clearing the thoughts from his head, he responded.
“I need to be certain this is not simply a one-time fluke. I intend to repeat the experiment, both with the original and try it in control studies.”
“Sounds like... a lot of work,” she said in a manner that Mace couldn’t be certain wasn’t flirtatious, “Say... where’s a good coffee shop around here? Wanna get some?”
Mace considered for a moment... there was no doubt now. She totally wanted him. Best of all, he thought, she wasn’t even his student!

Cory walked onto the brightly lit stage, squinting at the shadowed crowd before him. He was lead out by his master and wrapped only in a bedsheet. If he had ever been this embarrassed in his life, he certainly couldn’t remember. Luckily, he thought, at least with a crowd he wouldn’t have to worry about Mace trying to mount him. THAT would have been embarrassing.
“Esteemed colleagues,” the voice of his master boomed across the lecture hall, “Welcome. I am Doctor Mace Black, and my seminar today is on the use of human stock to restore endangered species populations. I also will be showing you today my research and results of human chemical transgendering and fertility. I warn you that some slides may be a touch graphic, so I ask for your discretion in these matters. And now, without further ado, may I present the first example of a fully fertile transgendered human male, Cory!”
The sheet was pulled away, leaving Cory standing completely nude on stage. His first reaction was to attempt to cover the feminine abomination between his legs, but as Mace had warned him against such things, he merely covered his face and prayed for it all to be over. His ears picked up the gasps of awe and surprise. He could feel the glare of the floodlights on his skin, the gaze of dozens of anonymous scientists upon him, the cool of the air conditioned room... but all he could feel inside was shame; the desire to shrink into a corner and never emerge again.
“That’s right!” Dr. Black crowed to the crowd, “We have had chromosomal modification technology for animalists for years, I have now made it work for humans as well! This hereby ends the problem of diminishing females. And on top of this, I will show you how it can be applied to any human to produce viable feral offspring.”
The black wolf watched eagerly as the few dissenting scientists excused themselves. To his delight, there were fewer than he expected. The remaining eyes stared back at him, demanding silently that he continue with his presentation before they ran him out of the halls of academia. Squaring his shoulders he gave them all a superior wolfish grin and launched into his computer slides.
Cory stood there, eyes closed and obedient, as Master Mace jawed on minute after excruciating minute, detailing the things he had endured at his master’s hands. Gratefully he excluded the bit about Mace repeatedly screwing him, pumping load after load from his crazy dog-cock into Cory’s heat-swollen canine-shaped pussy, fertilizing him, making him want it! At that moment the embarrassment melted away, replaced by anger beyond his ability to express.
Mace continued on to explain how his long-word-named chemical was able to remove the human aspects of an animalistic person’s DNA by extracting the sequences from the human “mother”, further adding to Cory’s inner rage. Soon after he was showing comparison slides, defining the physical difference between a feral wolf cub’s paw and an animalist child’s hand. He showed slides of the labor... 
“That’s IT!!!” Cory shouted, stamping a foot down on the stage. He jabbed an accusing finger at Mace, who stood by calmly with his finger hovering over the shock collar, “You might own me, you might have changed me, but WHY are you showing THAT?!”
Mace said nothing. Infuriatingly enough, he simply waited as if Cory was nothing more than a common heckler.
“I would have served you... I have served you! You... you inseminated me!!! You bred me like some common bitch! You made me have those... those THINGS! But I’m not an experiment! I’m not a female! I am a MAN DAMNIT!!!”
With that, Cory collapsed to his knees and sobbed. His cheeks were hot with embarrassment and spent anger. In one outburst he had gone against all the training he had endured to make him subservient to his animalistic masters. Above it all, Mace still stood completely impassive. After a moment to let the tension out of the room, he took back his microphone bead.
“Well... I hope that casts aside a few doubts as to the validity of my experiments. You can’t fake that kind of fervor. I’m sorry you had to see that, but I assure you it was necessary that you see the actual specimen. Especially since I was just about to proceed to the pelvic exam.”

“The puppies are nearly eight weeks sir,” said the caretaker, “They will begin the most receptive phase of their development in a few days. I have my staff ready with the training room. With any luck, they will be able to teach their own offspring if they are found to be fertile... that should take at least a year.”
Mace tapped his steepled fingers as he listened to the wildlife biologist’s review. He considered carefully this information, even though it was far from the forefront of his mind. The overwhelming approval of the science board had demanded results... and waiting for results was making him impatient. Moreover, Mellany had since broken up with him after her recent round of checkups and college reviews, saying that she was going to move to a different city to pursue her dreams. The result had left him a bit on-edge. These thoughts fresh in his mind, he gestured to the young cockatiel nurse down the panel.
“Your subject, Cory, appears to be recovered completely,” She chirped, “Additionally, thanks to his youthful vigor he seems to be well enough for the next round of tests. I find it amazing how quickly and easily he has recovered from his ordeal. I hypothesize that it is because of the small size of the offspring that...”
A black-furred hand silenced her with a wave, “Thank you,” Mace said firmly, “That will be all. You may return to your tasks or simply take the day if your departments are satisfactory. Please turn in your reports to Mrs. Hall by Monday morning. I have... a grant proposal to write, so don’t expect me around for the next few days. If you need anything, an email is best.”
He waited until they were gone. While they had attended their tasks well and were full of dedication... but none of them could resist an early weekend. Tension heavy upon him, he stalked the dim halls of his laboratory complex. Not even bothering to look, he made his way to a certain room on memory and scent alone. Unlatching the door and swinging it open, the scent of blood and heat wafted over his face. Arousal swelled within him, sending the wet tip of his hungry cock slipping free of his sheath.
Cory lay whimpering on his bed... whimpering like a bitch in heat Mace thought eagerly.
“Damnit... Damn you...” groaned Cory, “I knew you’d come for me again.”
“The reports say you are recovered enough that we can run a repeat experiment.” Mace replied darkly, “I think it’s time we got started.”
“I... I... I hate you... But... oh God I need you!” Cory rasped, his words nearly beyond his control.
“Don’t worry. Your days as a sideshow freak are nearly through,” Mace added sinisterly as his pants fell away, revealing his long tapered shaft to the needy human, “I just need a repeat with you and then we can expand our efforts to the rest of your race.”
Obediently, Cory crawled over to his master on hands and knees. Though his cunt ached for cock, he knew that his master needed a good sucking off first. Taking his master’s slick cock into his mouth, Cory wondered at a future where he would not be paraded around in the nude to show that a male human could grow a pussy.
“And just think how lucky you are,” Mace groaned as he felt the human’s small tongue swirl over his shaft, “I treat you better than most humans could dream, sex aside, and you’re fed well and have a comfortable bed.” He paused for a loud groan as Cory swallowed his cock deep down into the human’s throat, “It could be worse still, though. The science directorate is talking about replenishing the numbers of things like rhinoceros and pandas next. Just imagine one of THEM tearing that twat of yours apart.”
The moan that vibrated his cock told him that Cory was thinking of it, but not in any negative way.
“Alright, enough,” he commanded, “turn around. Time to start the next experiment.”
