A Fertility Shipment Gone Wrong

for BionicDragoon

by Draconicon

Fox McCloud wasn't in the business of shipping things, as a general rule, but with someone new on the team, it wasn't a bad idea to see how they handled something simple before throwing them into the thick of things. He knew that Krystal could fly the team's Arwings surprisingly well, but the fact remained that she hadn't gone through the same combat experiences that the rest of them had. Taking her through a basic guard-duty contract, something that would involve minimal piracy, if any, would give him the chance to see just what she was capable of without putting her in undue danger.

Of course, that meant that Peppy, Slippy, and Falco were staying back with the Great Fox while he and the vixen took the mission solo. There was no need for the rest of them for this. Just him, the larger freighter, and one Arwing would be sufficient for this. Provided that Krystal was as good as she thought she was...and he was able to keep her on a tight leash.

"So, Fox..."

"Hmm?" He looked up from the datapad with the details of their contract. Krystal was leaning over his shoulder, as she had been doing for the last few days, always studying what he was doing. "Yes?"

"Do you think we should examine the shipping container?"

"Why?"

"Just a feeling."

"...Probably, come to think of it." The vulpine pilot sighed, getting to his feet. "They'll try and shave some of the pay off if we bring it in damaged, even if they were the ones responsible for it. Come on."

The blue-furred vixen followed, her jumpsuit pulled tight around her body. Despite his constant efforts at professionalism, his eyes kept going back to her, taking in the sight of her curves, her femininity, her...well, everything. It was hard not to stare, even though she was no longer as near-naked as she had been when they had first met on Sauria. There was something more alluring about the jumpsuit, though, almost like it was intentionally putting her body on display.

One more reason that he didn't want her going into heavy combat, admittedly; he wanted to make sure that she was going to be okay, and that she was ready for all the comments that her state of dress were going to provoke.

They walked across the hangar, the robots going still and freezing the transfer of the shipping container. It hung in space, just a little over two feet off the ground, one end about to go into the transfer ring that would teleport it over to the freighter proper. He pressed his hand against the white-painted side of the container, tapping it. He passed the datapad over to the vixen.

"What are we taking for them again?"

"The contract lists something about medical chemicals. I believe that it says something about fertility clinics, as well. It is hard to...translate."

"Medical terms?"

"Somewhat. Also, legalese is not something that I am used to from my home planet."

"Heh, you should get used to that. It's not going to stop here."

Kneeling down, he lowered his head to the deck to get a good look at the underside. If this was going to a fertility clinic, then there was probably nothing to worry about, but it was never a bad idea to keep an eye on the bottom line. The mere possibility of getting blamed for a bad shipment when it might have been the employer's fault was -

"Oh, goddamn it."

"What is it, Fox?"

"Come here."

Waving her over, he pointed at the underside of the twenty-foot-long container. There was a large crack right along the bottom of it, one that was straining against the weight and pressure of whatever it contained. Whatever they were being hired to take across the galaxy, it wasn't going to make it there in one piece, particularly not in something like this. They'd have found it burst probably within a day, perhaps even within an hour, depending on just how bad it went getting it through the transfer ring and onto the freighter.

Fox shook his head, slowly getting to his feet. He dusted his hands off.

"Well, that's it. Contract's over."

"That's all?" Krystal asked.

"That's it. There's no way that we're carrying this. It's going to burst any -"

What happened next happened so fast that there was no telling just what had kicked off the whole thing. Maybe it was the supervisor coming down to the hangar to see what the hold-up was. Maybe one of the AIs in the robots failed at the wrong time and they pushed a button that they shouldn't have. Perhaps there was a malfunction in the hover-jets that were keeping the cargo pod off the ground, sending some upwards and some downwards.

Whatever it was, someone shouted, the cargo pod creaked, and then the crack turned into a full-blown hole. The pod strained and twisted, and then began spilling its contents everywhere, covering the floor, the loader bots...and Fox and Krystal.

Fox stumbled backwards as his vest and pants were soaked to the skin almost immediately, his eyes going wide as he realized just how soaked he was. The chemicals didn't burn, so it obviously wasn't too acidic or too far along the alkaline spectrum, but it was hot to the skin, doing something else, making him feel something...strange. Something off. Something...tight in his legs and between them, and something heavier and more swollen elsewhere.

"Nnngh...what...what the hell?" Fox grunted, only to grab at his throat. Something was wrong; his voice was going high. Too high.

As he gripped his throat, trying to rub away the strange feeling that something was wrong, he turned to Krystal. About to tell her to get someone from the medical wing, he froze, his eyes going wider as he looked at her.

The vixen was rubbing her chest. Normally, that would have looked almost lewd, wrong for the fact that she was doing something so...inappropriate in public, but this time, it was more natural. Not because she was doing something sexy, but because she was examining a pair of obviously shrinking assets. Her jumpsuit was no longer so tight around her bosom, and it was clearly shrinking in, pulling tighter to her body. Fox's eyes widened as he stared more than he had back when they'd first met, unable to look away as her breasts slowly shrank away.

"Fox? What...what's happening to...us?" She paused, rubbing her throat the way that he had been rubbing his. Her voice had dropped, just as his had jumped. "Oh..."

"Oh," Fox repeated. "Oh, shit."

The company staff finally arrived. Fox and Krystal were pulled away, dragged apart while their vitals were taken. They could still see one another, though, and that made the transformation that they were both going through that much more intense, that much more...strange.

Fox could feel things changing under his clothes. Even as the medical personnel were clearing him, ensuring that he wasn't going to have a heart attack and die out of nowhere, he could feel his chest getting heavier. He'd always had good muscles, and those remained, but there was something different about them. His chest felt like it was swelling, and when he pulled at his vest, looking beneath it, he could see that he had a pair of breasts that were slowly pushing forward. His nipples were more obvious through his shirt, and that menat that he was -

"Nnngh!"

One of the medical staff touched him, barely brushing him, and he gasped at the sheer pleasure that came from getting touched there. He blushed, looking away, and the medical grunt did the same.

Fox tried not to stare too much, but as Krystal changed, it was clear where some of the changes were going. Her shoulders thrust out more, making her look more masculine, and her chest, her breasts, completely flattened out. They were replaced with pecs. Not overdone ones, not huge ones, but the sort that someone like her might have had, well-developed after her time as a more physical warrior. And further down -

Holy...

He stared at the dropping balls down there, the development of a sheath to replace whatever she'd had down there before. He was used to seeing something like that, of course, as he had one himself -

Had. Had had one himself. He could feel it shrinking away, dragging in, pulling towards his insides. He reached down, touched himself as the medical grunts pulled away. He had no balls anymore, he belatedly realized, the pair of them having pulled up inside. His shaft, his sheath, was slowly getting sucked away, pulled into him just like his balls had been, and his cheeks burned as he felt something else, something almost like a hollow space behind where his balls had been, something that was slowly opening up and giving way, only needing something to open up to allow someone to touch it from the outside.

I'm turning...she's turning...

"Fox."

Krystal's deeper voice caught his attention. He looked up, just in time to see that the medical guys were leaving her, too. Leaving Krystal. Leaving him; she was a him. There was no denying that bulge even as her hips were still there, even if they were shrinking away.

"We better...better get back to...the freighter," she muttered.

He couldn't agree more.

Going to their separate quarters was the first thing that they did. They needed to see what had happened to them in full, and Fox needed to see what was going on between his legs. He knew what he was going to see, but he didn't want to admit it. He really, really, really didn't want to admit what he was probably going to see down there, but there was no getting away from it. He had to check.

As soon as he shut the door behind him, he pulled off his clothes. The sight of his breasts, still coming in and well more than a handful in size meant that he was going to need some serious support if this was going to be the new normal. He groaned under his breath, running his hands over the new globes, trying not to touch them too much. They felt so sensitive compared to what he used to have there, and he almost wanted to keep feeling them up, to get off to the feeling of having these things, but the simple distraction of the continued shrinkage down below...

That was important. Too important not to pay attention to. He walked to a mirror, spreading his legs and looking.

His cock had gone from six inches to two, and it was almost gone, now, sticking out over the beginning of a pussy. It wasn't the slit of some alien species, but rather the tight little 'cookie' of a fox pussy down there. He shivered as he watched it continue to swell, growing larger, taking up more space down there, sticking out just enough from between his legs to look like the wild species that they had evolved from. He curled his toes at the sight of his cock slowly getting sucked into that, turning into some kind of clit.

Those chemicals...must have been for...for allowing people to change genders...carry children or have them when they couldn't before...

That would explain the warmth that was rushing through him from down there. There was something in the chemical that encouraged those being changed to want to breed, to get off to it, to enjoy the process and want to start it. After all, if you were going to a fertility clinic to change, you wanted to be able to...to want to...

"Nnngh..."

Despite himself, Fox reached down, running his fingers past his disappearing cock to the forming sex just behind it. It was swollen and sensitive, begging for the touch of someone that knew what they were doing. His fingers were clumsy, had difficulty finding the right spot to touch, but he moaned as he felt something, anything down there. He started to rub up and down along the puffy sex, feeling how it clenched around his fingers, how it wanted more than it was getting. Fox humped forward, slid a finger inside -

"Ah!"

He gasped to himself, almost falling to his knees from the sheer pleasure of having something inside of him, even if he was so tight that it was a little painful at the same time. With his thighs trembling so much, it was a wonder that he was managing to stay on his feet. His toes curled against the metal panels beneath him, and he moaned under his breath as he looked at himself in the mirror.

Herself? Yes, that was probably what the galaxy would think at this point. He was more of a she, a vixen rather than a fox, and she bit her lips as she looked at the way that her nipples poked from her fur, how she felt like...like some sort of breeding girl.

That's not what you are...

But it was what she was being made. She just hoped that Krystal was -

Snikt.

The door opened behind her, and she whipped her head around. Krystal was just as naked as she was, and unlike Fox, Krystal didn't seem that bothered by the changes. The blue fox had a cock that put her old one to shame, and Fox blushed worse as she realized just how much this transformation must have been affecting the new crewmate.

"Krystal -"

"No. No talking. We both...we both know what we need..."

There was a glint in her - no, his, his, with that throbbing, tapered, knotted cock - eye that meant business, and Fox had little hope of pulling back and getting away without getting bred. Hell, she wasn't sure that she really wanted to get away; the need between her legs had grown so hot now that she didn't want to think of anything but the feeling of that big cock buried in her new pussy, stretching her out, giving her what she needed.

Even as her mouth worked soundlessly, trying to find some excuse that would work against the chemicals rushing through their bodies, Krystal grabbed her by the shoulders. Fox was borne backwards, pushed further and further towards the bed in the corner of the room. She fell, landing with a bounce, and then had her legs spread wide, her pussy bared to the world.

"Mmmph...don't...don't...we don't know if this is..."

"I don't care," Krystal whispered.

"Mmmph...you..."

"And neither do you...I know what a woman wants...I was one...and now, you can learn."

Krystal slid himself between Fox's legs, and that throbbing, heated thing that pressed against her pussy was just too warm and too hard to really be real. It felt like something impossible, something out of a simulation, something that would be gone in just a second if she was able to actually focus.

Then the tapered tip found her sex, pushed in, ground forward. She gasped, her eyes going wide as she felt the parting of her inner walls. Something else gave, something that was slightly more painful, but it was so overwhelming that there was nothing she could do or say to slow it down. All she could feel was the pressure, the heat, the warmth of that cock going deeper and deeper into her body, reminding her of how good it felt to get on her back and allow someone else to do the work.

"Ah...ah..."

Krystal loomed over her, the blue fox aggressive, but not cruel. Inch by inch, that throbbing cock pushed into her, and Fox's new pussy took it without complaint. In fact, it took it with wet eagerness, taking the whole thing and wanting more. She arched her back, gasping for breath as Krystal's knot pressed against her pussy sex, about to slide in, about to take her and seal them together...

Only for the blue fox to pull back, dragging his shaft free. Fox gasped for breath at the emptiness that followed, begging wordlessly for it to go back inside.

She got it. She got it deep.

The bed squeaked and complained under them as Krystal hammered home again and again, each thrust stretching out that new pussy, making it feel properly used. Fox's cock had long since disappeared, becoming a tiny little nub hidden away in her new folds. In, out, in, out, each thrust taking her further and further down the road to orgasm, her chest rising and falling, her eyes rolled back in her skull.

There was nothing more to say between the two of them. Huffs, grunts, groans, that was all the language that they had as they explored their new bodies. Krystal's touch was expert, touching and fondling her where she needed it most, and Fox took it, unable to bring forth the will to do more. She was entranced at the taking, submitting in a way that she had never done for anyone in her life.

In, out, in, out.

The pounding kept up, the knot slapping against her pussy, forcing her open as it struggled to get inside of her. A little more, a little more, the pressure from above increasing as the speed of the thrusts slowed. Fox took it, spreading her legs wider, trying to give Krystal the space the fox needed. In, in, in, that knot went, almost at the midway point, stretching Fox's pussy in a way that she didn't know it could have been stretched. It burned, it ached, but it felt so, so good.

Out, then down again, pressing in, almost grinding past the point of no return. Her pussy was wet, the cock was hard, and Krystal, despite being in charge, was moaning as much as she was. They were both lost to the sensations of their new bodies, unable to stop.

Harder, grinding, hotter, stretching -

POP!

And then it was in. Fox gasped, her eyes going wide, and then wider as she felt the pumping, throbbing, pulsing feeling of a cock that had finally given in to the inevitable. She was getting filled, pumped full, hot seed going right into her middle and filling up her womb whether she was ready for the responsibility of cubs or not. She was going to get some, particularly with a load this thick and viscous.

"Ah...ah...ah..."

"You needed that," Krystal whispered. "And I think...I think I did, too."

"That was...amazing."

"You're going to get more of that."

"Mmmph...where do you get off telling me what to do?"

"You were keeping me away from action...now I can do the same to you."

"That's not - mmmph..."

The little twitch and tug of that cock inside of her was enough to stop her protest, and by the time that she had cleared her head, Krystal had slid in bed behind her. They were spooning, that cock locked inside her, pumping a little more cum into her womb, making it that much harder for her to believe that she wasn't going to get pregnant.

"We'll talk," the more aggressive Krystal said. "But I think...I think this could be good."

Fox wasn't so sure, but until they found out what this chemical had done to them, and how permanent it was...well, she might have to get used to it. And from the feeling of that knot down there, it might not be that bad, really. Once she got used to it.

The End

Summary: Fox and Krystal are taking a simple job of delivering some chemical cargo so that Fox can see how good she is. However, the mission's gonna be complicated before it even starts...
