Shane pored over all the documents on his desk. For the last six months, the shark had been tirelessly collecting every report about a kidnapping or “forced gender shifting” in his home area and every state and country surrounding it. He had gone online to every discussion forum and server that he could think about, and he had asked there too; did they, or anyone they knew, know anyone who had been kidnapped?

Then, if they said yes, he asked a few more questions.

Did they end up imprisoned in a highly technical bunker with machines and sex toys?

Did their kidnapper indicate that she believed she had some sort of higher goal, that she was a kind of punisher who would set things right?

Were they forced to participate in some kind of challenge that was impossible or nearly impossible to win, regardless of how strong or smart the participants were?

Did male victims end transformed into females? If already female, were they impregnated against their wills?

Then there was the most important question, the one that truly determined whether or not Shane took a closer look at the case, unless everything else fit perfectly:

Did the kidnapper wear a mask, possibly of a zebra?

Seven months ago, Shane and his two best friends had been in that situation. The kidnapper who he called the “Zebra-Mask Zebra” – owing to the fact that she was most likely a zebra wearing a redundant zebra mask to conceal her true identity – had somehow captured him and his friends and subjected them to a sadistic challenge.

She had tied them all to chairs that would eventually make them cum. The challenge was to not cum, but there had been no way that Shane could perceive for all three of them to escape the challenge, making the orgasmic failures inevitable for at least two of them.

Victor, the donkey, had been the first to cum. She was now known as Victoria, and though she harbored some bitterness over what had happened, she was happy as woman, and would soon be ready to deliver her first child.

Then, there was Milo – now Mila – the bear, and the second to cum. He had just as mercilessly been transformed, and she, too, was surprisingly fine with what had transpired. Though she had been angrier than Victoria at first, she had quickly noticed that she liked all the attention her thick, curvy, voluptuous body brought her.

“Don’t particularly mind, really,” she had told him. “It’s much easier to get laid like this. ‘sides, I’m pregnant already, so there’s no harm in it, is there?”

They were both probably pregnant after Shane had been forced to fuck them with cum-filled dildos to prevent them from forcing themselves on him. Though, as one would expect of an inexperienced woman “getting laid” a lot and enjoying all the men she could, Mila had just about ensured that she was.

Shane, though he had been released once his friends had lost, was the only one still furious about what the Zebra had done. She had told him that it was punishment for his alleged misdeeds, for some sort of misogyny that he was supposedly guilty of despite him having no idea whatsoever. The self-righteous attitude infuriated the shark, but more than that, he was traumatized. The experience had left him with a twisted determination to chase after the Zebra, to catch her and to unmask her for the world to see to get some justice for her victims.

The problem was that he was nearly unique. The Zebra had some sort of skill in picking her victims. Almost all of them were happy or at least okay with the results. Their lives had turned out better, or so they said. Maybe it was a result of whatever she used to transform them, or just biological satisfaction over being impregnated. That made finding information extremely difficult.

Thankfully, a few victims had reported the events to the police, less because they wanted her punished, but more out of an ingrained desire to help justice. Even if they were happy, after all, they couldn’t presume that everyone else also would be, so they helped.

Not that they had much to say. The Zebra appeared to have excellent operational security. Nobody had, or so they said, seen her without the ever-present mask. Nobody had seen where exactly her secret bunker lair was, either, beyond that it was in a leafy forest, and that it was somewhere in the countryside, going by how long it had taken for her to transport her victims, Shane among them. He had been kidnapped on a Friday night, so the trap had been sprung on Saturday, and he had been returned home that same Saturday, which was also when he became aware of time after being tranquilized on his way out.

That said, he had bought a paper map, and on it, he had placed a pin in every location where a matching kidnapping had been registered. They formed a somewhat uneven circle around one of the smaller major cities of the area, and that was the biggest lead Shane had found during his stint as a newly minted private investigator out for vengeance. As cliché as that was, he was determined to see it through, and it didn’t feel like a cliché. Nothing did, when you were the victim.

In that particular city, there was a club. And sure enough, that club was very close to the pub where Shane remembered being with the friends who were now known as Victoria and Mila. He had been a little too drunk to remember the events of the entire night, but that big, popular nightclub was as good a place to look as any. If he was lucky, he’d catch the damn Zebra there. At least, assuming that she was a zebra.

Shane sighed. He rubbed the bridge of his nose, fighting back the feeling of somnolence. He hadn’t slept well recently. Many nights, he dreamt he was back in the Zebra’s trap, and every time he dreamt about it, he lost whatever the challenge was. The worst part was that losing felt amazing. Getting transformed into a woman and then knocked up against her will. It had become a love-hate fetish fantasy for him, and that perverted appeal might have played a role in why he was so hellbent on finding the zebra. He needed to confront her and see her brought to justice – real justice, not the twisted kind that she sought – to free himself of those fantasies.

So that night, he found himself at that club. It was either today or tomorrow, if the Zebra was currently stalking for victims. It might be that she wasn’t. That she had sated her hunger for “righteous” revenge on evildoers and retired.

But Shane didn’t get the feeling that she would.

There was another risk, one very present in his mind as he joined the crowd, moving to the beat as one living organism among the many colorful lasers sweeping over it. There was the risk that he’d get kidnapped again, and there wasn’t a whole lot he could do about it if the Zebra saw him first. He did have a backup plan; his phone, hanging around his neck, was recording everything, and would be until the battery ran out.

On the other hand, if he saw her first, it’d be a different story. Pound for pound, he was fairly sure that he could wrestle her down and hold her down until the police arrived.

The music was fantastic. It resonated through him as he quietly swayed along with the rest of the crowd, scanning one direction and then the next. Somewhere in back, he saw two shapes grinding together. The Zebra might choose them to punish but he saw no Zebra. It was difficult to see anyone in the crowd, even with him being almost a full head above the average.

He felt like he was being watched. But then, someone brushed against him in the darkness, his right shoulder. Shane spun around immediately and found himself standing face to face with a zebra. Not one in a mask; a zebra, plain and simple, with a long raven-black mane and purple eyeshadow. She had a mean grin on her face, the kind that immediately told Shane everything he needed to know about her. This was her. This was-

-he let out a pained yelp as a needle pierced his neck, at the same time as a pair of rough hands grabbed him from behind. The Zebra had helpers! She had helpers, she-

-Shane was out like a light, off to the dark land of unconsciousness in which, at least, he was spared from those dreams of transformation, as he was carried out of the club. Too drunk, his “friends” told the bouncers when they asked, and nobody asked the Zebra twice. The ones who did, found themselves becoming part of her experiments in justice-seeking very quickly, and those who didn’t, well. They knew those who did.

But for Shane, none of that mattered for a few quiet, blissful hours that were more restful – despite the drugs – than any natural sleep he had been blessed with since that first time in the Zebra’s trap. The one where he’d soon be again, reliving the same nightmare, only now it was reality once more.

When Shane opened his eyes next, it was in a dreadfully familiar room. The same circular shape, the same mechanical arms and the same monitors. Only this time he didn’t find himself with two of his best friends, but with a woman. A rather curvy ferret whom Shane had never met before, but who was just as naked as the shark, and sitting in a chair just like his.

“Not again, not like this!” Shane shouted, and just as he moved his arm as if to struggle, he realized that he wasn’t tied to the chair. An oversight? No, that was unlikely. He stood up and dashed the door regardless, and as he had expected, it was closed. Locked. Whatever the trap was simply didn’t involve him being tied down, which meant it had to include the ferret.

The ferret, for her part, had been woken up by Shane’s loud voice and the sound of his fists banging on the solid steel door. She looked scared, which was entirely understandable, but she summoned the courage to speak, regardless.

“Um… where are we? Who are you?” she asked, in a voice a little huskier and deeper than her small – but indeed, voluptuous – form would’ve suggested.

“We’ve been kidnapped by a psychopath who will use us for her entert-” Shane exclaimed, angrily, but just then, the monitors on the central pillar of the room flickered to life. On each, the Zebra’s redundantly masked face.

“Ah, I’m glad you’re both awake. It’s high time for our next little game. This one will last a week,” she informed them. A week? Shane wanted to yell at her, to tell her that he knew who she was, or at least what she looked like, but he knew that the video was merely a recording. “A week of you two trying to resist the urges that caught my attention to begin with. You’ve both been judging others who enjoy their carnal pleasures…”

“What the fuck are you talking about?” the ferret yelled.

“It’s a recording, she won’t respond even if she hears us,” Shane told her.

“You, Shane, hold a grudge against your friends, for surrendering the last time you found yourself here. For failing. But what choice did they have? No man lasts forever,” the Zebra-Masked Zebra spoke, in her usual malicious but measured tone.

“And you, Sandra, you didn’t like how your best friend let a man you don’t like knock her up after enough seduction. But isn’t it natural for women to do so? We shall see how you handle the same temptations,” she continued.

There was a hiss, above them. Shane looked up. A faint purple gas was filling the room.

“A little aphrodisiac to get you both in the mood,” the recording told them. “There are also condoms that will be delivered daily. It’s up to you if you want to use them, or if you simply want to roll the dice. Or if you want to face your own weaknesses and surrender. Either way, should you fail, there is a punishment in store for you both, or perhaps, a blessing, given how sweet surrender can be…”

The Zebra was a lot more vocal than last time, Shane noted. She must have gotten more confident with success.

“If you, Sandra, end up pregnant – that’s it for you. You will never meet this man again, and will get to raise your new child alone, as punishment for submitting to the same risky desires that your friend did, that you judged her for.”

She raised a finger, though unfortunately one covered by a black leather glove.

“And if you, Shane, do knock her up, you will end up as a woman yourself. Just like the friends that you judge for losing your last challenge. Just like you have been dreaming of. And then you can, at your leisure, get yourself saddled with a baby as well, because we both know you won’t be able to resist.”

She paused for a moment.

“But you will both get a fair chance. After all, I have provided condoms,” the zebra laughed. “You will also get fed. Don’t think of me as a cruel mistress. I’m merely a teller of truths, here to help you understand yourselves better.”

All at once, the monitors went dark.

“I see what you mean with… psycho-” the ferret – Sandra – whispered quietly, before she began to cough. “F-fucking aphrodisiac? I hope you’re not planning to do anything.”

“I’m not, I’m not. I survived one of these sick games before,” Shane replied. He looked at himself. He was still a man. He would remain a man. Broad frame, muscles, his two cocks. He tried to commit that self-image to memory, in case it was to change. “I promise you, we’re not going to do anything,” he reassured the ferret.

“Good,” the ferret replied, her voice sounding like a sigh of relief more than anything, though she was squirming on her chair. The gas was already getting to her.

It was getting to Shane, too. Both of his cocks were growing hard. He chose to pay that no mind. He was not going to let the zebra win. He had to get out of here so he could expose her. His phone had caught her real face, and no matter what his captor did, she couldn’t delete that footage, or even find it. From the phone, yes – by destroying it. But from the online backups? She wouldn’t even know about it.

First, though, he had to work out a plan to get out. The easiest was simply to last a week. He sat down in the chair that had held him prisoner six months ago with a heavy sigh, deliberately ignoring the throbbing of his cocks, and the fact that Sandra kept stealing little glances of them.

“How are we going to make it?” she asked.

“We just don’t fuck. Or if we do, we use a condom,” Shane growled. The aphrodisiac burned in his lungs, soaking into his blood and fueling all those fiercely masculine desires in his loins. It felt like his balls were in overdrive already, churning to produce the cum that the Zebra expected him to fuck Sandra pregnant with. He knew that just masturbating wouldn’t even take the edge off, and so did she.

“But you… you have two cocks,” the ferret squeaked. “Sorry. Sorry for looking.”

“I do, so wh-” Shane replied, and then went quiet. Fuck. He had two cocks. Cum erupted from both when he came. There was only one condom. That meant any sex would result in him, at a minimum, splattering Sandra’s lips with his seed. That was too close. And why was he even entertaining the thought? “-let’s eat. Please? Take our minds off… this.”

Eat they did. There were two trays of food, both delivered by a perfectly quiet and unseen figure through a slot in the door, one that could only be opened from the outside. It was plain. A bowl of potato and carrot soup with chunks of meat – it tasted like some cheaper cut of beef – and a slice of dark bread. It was neutral, very neutral in flavor, with only the slightest hint of spices, and Shane cursed the Zebra under his breath. Of course it was plain, so that they’d both have to seek pleasure in each other to stave off boredom.

The gas had stopped flowing, but the effects persisted. He could smell Sandra’s wetness and feel his own arousal. The ferret sat there, eating slowly with a far-away look in her eyes. The shark couldn’t tell if she was thinking or trying to fight the urges the gas had sparked.

Gods, was she beautiful, though. She had those kind of perfect teardrop breasts, heavy and full, that drove Shane wild just to glance at. She had a flat, well-trained belly that had undoubtedly never experienced the scarring swell of pregnancy. Shane fought back the inevitable fantasy of making it happen, and then the thoughts about how she would look pregnant with his child. Every now and then, he caught Sandra glancing at him, probably ridden with similar thoughts. How could she not be?

“Do you really think we’ll make it? I’m not ready to become a mother,” the ferret finally spoke. “I have a whole college education I need to finish, and…”

She trailed off, realizing that she was pleading with someone who wanted to fight their captor just as much as she did. “…and I- I’m-”

“Yeah, I know, me too. The Zebra always cheats. The aphrodisiac isn’t fair, and I’m pretty sure the food is laced with it too,” Shane sighed. There was a warm glow suffusing his body from his stomach. Maybe not another aphrodisiac, but some kind of anxiolytic to make him feel like it wasn’t such a big deal. The worst part was that it was working.

But what choice did he have? He couldn’t not eat for an entire week.

There was, as one might’ve expected, only one bed – or mattress, rather; it didn’t deserve to be called a bed – in the room. Everything was distinctly chosen to force the two of them closer. Shane noticed a chill in the air, as well. No doubt so that they’d have to be close together to keep warm during the… night. Whenever night was. Shane got the feeling that it was probably late in the evening, though he couldn’t put his finger on why he thought that. It might as well have been early morning.

She seemed to be hovering somewhere between despair and anger. The shark couldn’t figure out what her expression meant, but he left her to her thoughts for a moment as he stood up to examine the room. The chairs were still there, but all the mechanical arms were inactive. The sex toys were gone, no doubt to deny them the chance of easy masturbation. Above them, there were vents, probably for both air and the aphrodisiac the Zebra was using to “prove” her twisted point. Too small to do anything with.

The door was far too strongly reinforced to pull open, even with all of Shane’s muscle. He was strong – another thing he’d lose if he got transformed – but not that strong. Nobody was that strong.

There was a tiny room that had a toilet attached to it, thankfully. And then there was the mattress. Nothing else.

Shane tried to hang on to the anger but whatever was in the food was relaxing him, no matter what he wanted. His thoughts drifted from righteous fury to places he didn’t want them to. And he was hard. Painfully hard. There was no getting away from that either; he didn’t look down, but he could feel his precum oozing down his shafts. Between the aphrodisiac and his natural libido, abstinence wouldn’t really be an option. Maybe he could grind against her without slipping in. But what if he did? Would he be able to stop?

He turned back towards the ferret, who seemed to be breathing heavily, just as affected as he was.

“We’re not gonna have the slightest chance, are we?” she whimpered. “I’m so… so fucking horny.”

Hearing her say that made both of Shane’s cocks throb. He was leaking, too, which was spreading his own pheromones in the air where they mingled with the ferret’s fertile scent. It turned her on more, and she turned him on more in turn.

“We could just fuck,” he suggested, quietly. “With the condom on. And me trying to not go… inside.”

“Yeah,” she huffed. “Really unlikely that anything would happen, right?”

“As long as the Zebra didn’t sabotage the condom,” Shane pointed out.

“Fuck, you’re right. But even then… my friend had to try for like, a year before she got pregnant?” Sandra argued, again pleading with reality to perhaps accommodate the growing, burning need between her legs.

It felt good to think of it that way. How many couples struggled to have kids. Maybe none of this was such a big deal. Except Shane knew it was a big deal.

Still, he inspected the condom. It looked intact, but would he even have been able to see the hole left by a thin needle? It’d be plenty big enough for his swimmers to get through even if he couldn’t.

But he couldn’t hold it. He was going to explode, or Sandra might pounce him unprotected if he didn’t do something. She actually looked even worse affected, and Shane knew from experience that feminine arousal could be even more overwhelming than what he felt. He told himself he had no choice but to do it as he unwrapped the condom and rolled it over his upper cock.

“Just try to… not move, I’ll try to thrust gently, so the rubber doesn’t break…” Shane panted as he knelt between the curvy ferret’s legs. She was soaked, and in visibly desperate need. It looked so incredibly hot. He was almost as wet, and the both of them had left little pheromone-laden pools of arousal where they’d been sitting.

He carefully placed his latex-covered tip – already with a visible droplet of his precum caught by the end of the condom – at the ferret’s entrance, and, with a gentle thrust, he pushed into her. The heat and tightness were both amazing, and the shark couldn’t help but groan. Yet, as he tried to thrust deeper, the tip of his other cock – the bare one – brushed against the ferret’s slit as well, smearing his slick masculine lust over her folds, and that touch was even more intense and electrifying.

But he couldn’t let himself enjoy any more of it. Each touch of precum might have sperm in it, and he might slip deeper and lose his self-control. With a frustrated grunt, Shane pushed his second cock down so he could thrust a little deeper and enjoy the feeling of Sandra’s slick sex engulfing him. The pleasure was almost blinding even if it was woefully incomplete. It’d be enough to make him cum, and that’d take the edge off. Her, too. The ferret already had her striking green eyes screwed shut as Shane softly rutted into her. Careful little bucks of his hips. He kept almost sliding in with his second cock. Couldn’t let that happen, no matter how good it’d have felt.

Still, his pleasure grew and grew. Sandra’s heavy breasts bounced with every motion, and Shane couldn’t resist grabbing one, squeezing it softly in his hand. Her nipple was stiff as a little diamond against his palm, and she was already shivering with deep, carnal pleasure with each little buck of Shane’s hips.

It didn’t take her long at all to cum. Something, though Shane couldn’t tell exactly what, excited her a lot about their current predicament. Convulsively, Sandra moaned as she wrapped her legs around Shane’s waist and came like a firecracker, thrashing and squirming underneath the shark with such enthusiastic passion that he could barely keep her in place. And her inner muscles milked him towards his own orgasm at a rapid speed. Before Shane even knew it, he’d passed the point of no return.

Fuck. His second tip rested against Sandra’s lips again. It kept returning to that position unless he was actively holding it down, it seemed. But he couldn’t do anything about that with her legs squeezing around him like a vice, or he’d be pulled in deeper. Nor could he stop the firehose of cum that erupted from both cocks at once, fueled by the aphrodisiac and flooding the condom – and the other half splashing against Sandra’s pussy with enough force that he was worried and perversely excited by the idea of it going inside her. But the orgasm itself was beautiful, even if it took fighting his own body to not thrust both shafts deep into the ferret’s fertile depths.

“Y-you didn’t… didn’t, right?” Sandra asked him as their mutual orgasm ebbed. Shane shook his head; he still felt the condom around his cock, though it was bloated like a ballon with his cum.

“I didn’t. But you should clean up. Quickly,” he groaned, forcing himself to pull out again and then rolling over onto his back to pull the condom off. He felt better than he had in years, perhaps owing to the simple satisfaction of relieving the sexual hunger that the aphrodisiac had caused, and he had now sated.

Sandra quietly wiped herself off, fretting about how deep inside her Shane’s cum might’ve gotten. But she, too, was deep in the post-coital glow, and combined with the drugs from their meals, it felt very difficult to truly worry about it.

They both quickly fell asleep after that, still sticky with each other. But at least the crisis had been averted. She was astronomically unlikely to have gotten pregnant, Sandra thought as she drifted off into dreams. Though having the shark’s risky, sexy, thick, and hot cum splash against her slit was certainly an intoxicating feeling, almost making her very womb twitch as she imagined it going even deeper. Perhaps pumped there directly by both of the shark’s cocks.

But she didn’t want to get pregnant, she reminded herself.

When Shane woke up, it was apparently time to eat again. It was so easy to lose track of time with no natural light and nothing to tell what time it actually was, either. Sandra was already awake, slowly eating her soup spoonful by spoonful. When she noticed that he was awake, too, she blushed.

“Um… thanks for… last time?” she said. “We probably should- I mean, shouldn’t risk that again?”

“I think we’ll have to,” Shane replied as he sat down to examine his food. It smelled like normal, but he knew that eating it would dull his ability to assess risk, remembering yesterday. It’d feel acceptable to slide inside the ferret again, to risk some errant sperm spilling into her. It’d probably feel great to just let it happen, too. Without a condom. To fully roll the dice and toss caution to the wind.

And then keep doing it until he was a woman and could also get bred.

Shane closed his eyes. He had to eat. His stomach was growling at him, hurting from how empty it felt, and if he didn’t eat, he’d be far too weak to fight when they were let out. And so, he slowly began to spoon the flavorless, drug-laced soup into his mouth.

Above then, there was that familiar hiss. Shane didn’t fight it as the aphrodisiac gas filled the room and his cocks quickly responded, swelling up to full hardness, and his mind began to fill with those unwanted fantasies, as his pulse quickened.

“D-did we get another condom?” Sandra asked.

“Yeah,” Shane replied. There was one on his tray. It looked exactly like the last one.

The ferret looked at him with that same charming, intense blushing on her snout. “Let’s use it,” she suggested, her voice barely more than a whisper.

“What if we need it later today?” Shane asked.

“We can… reuse it? It’ll be fine,” the ferret whimpered. She was already rubbing her thighs together. “It won’t break that easily. They test them with like… liters of water…”

Yeah, but rubber weakens quickly, Shane reminded himself. Still, he moved almost on autopilot to roll the condom on and once again push his covered cock into the ferret.

Just like last time, he managed to first fuck her, and then himself, into orgasm, without his second cock slipping into the ferret’s fertile sex. But as before, his cum splattered Sandra’s labia, leaving the ferret trembling as she tried to wipe it off without applying any pressure with her fingers. But they were, at least, satisfied for a few hours. It seemed whatever was in the food also made them more tired, because soon both were asleep again, huddling up against each other to keep the cold out.

For a few more days, they continued like that. They woke up, ate, fucked – Sandra wiped his cum from her crotch with post-orgasmic clarity – and then spent a few hours staring at the dead monitors, anxiously expecting the Zebra to pop up and announce their failure. Yet, she didn’t. It had to have been at least five days of that.

On what might have been the sixth morning, there was no condom on the tray.

Shane was the first to notice that, as he began to eat his drugged meal. Apparently, the Zebra had lied about providing them every day. It didn’t initially seem like a big deal, with the food taking the edge off his anxiety. But the more he thought about it, the more he realized that it meant he couldn’t fuck the ferret. Didn’t it? If he fucked her without a condom… that was that. She’d almost certainly get knocked up, and that was kinda hot- wait, he couldn’t let the damned Zebra win!

Sandra had noticed what was wrong at that point. She bit her lip as the aphrodisiac flooded the little room again. If Shane was struggling, she was worse. She was already coming up with excuses for why it wouldn’t be that bad to get fucked bare. Or if not bare, then reuse a condom. They did test them thoroughly, that wasn’t a lie. It should be fine, she told herself. It was a stupid excuse, and she knew it, but the shark’s cocks felt amazing, and she had been fantasizing about them almost constantly since their first time because of the aphrodisiac spray.

“We shouldn’t,” Shane grumbled, remembering what the ferret had suggested yesterday, but the glassy-eyed stare in her eyes suggested that she wouldn’t be very receptive to reason. “It’s not safe.”

Safe or not, he needed it too, badly. The ferret was incredible in every way, though maybe that was the aphrodisiac speaking. Or the anxiolytics. He almost felt like he was in love, and he wanted to hear her moan again, wanted to make her feel good, as hazardous as it’d be. The Zebra’s master stroke had been to get them used to fucking and then… withdrawing what little safety they had, leaving them with the addiction.

“Please? I just… I can’t,” Sandra groaned. “It’ll be fine, right? It’ll be fine.”

She had the disposition of a woman in heat. Maybe that was the trick. The gas had triggered her heat rather than merely arousing her, meaning she would be extremely fertile, and rather incapable of basic risk analysis.

Shane glanced at the condoms they’d used. He had tried to squeeze out his spent seed from each of them into the toilet after each use, and cleaned them with the limited water they got, just in case Sandra lost control, or the Zebra tried anything, but they were weakened regardless. It was his turn to gnaw on his lip. Leaving a woman in heat without any relief was too dangerous. If it came to it, he could just… no, he didn’t want to hurt her, either, or he’d be no better than their captor. So, what was there to do except what she wanted?

“Fine,” Shane replied in a hushed, serious tone. “But if you feel it break, you have to tell me, right away.”

He wasn’t expecting to notice it himself, if it happened, with how much he had to focus to not accidentally thrust his second cock in.

“I will, I will, now just please fuck me, it’s like I’m b-burning up,” Sandra groaned. Her thighs were matted with juices. “I w-won’t even blame you if you… if you fail.”

There was one of those excuses again. A subtle carte blanche for Shane to breed her, if he wanted. As she might have subconsciously wanted, at that point. Sandra refused to think about what she was saying, instead watching intently as Shane rolled on one of the used condoms, the one he thought seemed least stretched.

The rubber, as he sank back inside the ferret’s welcoming sex, felt thinner. Less safe, certainly. But the feeling of her squeezing around his protected shaft felt heavenly as ever, and that was when a perfect, dirty idea came to the shark. He could use two of the old condoms and finally fuck the ferret the way he was meant to. The idea was so erotic it almost made him cum on the spot, but Shane resisted the urge, instead grabbing another one of the used and cleaned rubbers and pulling it over his second cock, which he finally pressed willingly against Sandra’s folds. He was still leaking like a faucet, just as wet as she was, in a sticky show of his desire.

Then, in one fateful, smooth, and deeply instinctive thrust, he sank fully inside her soaked body. Sandra moaned out in ecstasy as she was stretched wide, and with the rubber in turn stretched so think that it felt twice as intimate as before. Almost like he wasn’t covered any longer. As if the friction of his first thrust with both cocks has torn the latex. But Sandra didn’t say anything. She didn’t know, and even more so, she refused to think about it. And it wasn’t a big deal even if it happened. She absolutely couldn’t bear the thought of her clenching pussy being left empty again, even if it meant the shark unwittingly squirting every drop of his seed into her.

Shane huffed and moaned. Just moving slowly was taking all of his willpower. Every fiber of his being was screaming at him to fuck the living daylights out of the ferret, to rut and breed her, but if he gave into that primal side of himself, there was a very real chance of the condoms tearing, worn as they were.

All of this was too risky. Too risky. The thought echoed in his mind, but he couldn’t focus on it. He was doing exactly what the Zebra wanted him to do, he was being manipulated with simple chemicals like some sort of animal teased into breeding another and ignoring the consequences. Why did it turn him on so much?

Fuck. He kept thrusting. The vents above hissed again, coating the two half-willing lovers with another dose of aphrodisiac. Shane could feel it clouding his mind, and yet he felt like a stallion, horny and powerful and… single-minded. The more aroused he became, the more his thoughts flowed sluggishly like molasses, or cum, or not at all. His world was entirely just the white-hot squeeze of the ferret’s cunt around his cocks, feeling her slick heat caressing his shafts, milking them for his seed.

He tried to focus, regardless, in a heroic effort to pay attention to how the penetration felt, in case something did go wrong, while also picking up the pace and fucking the helplessly heated ferret in firm, powerful thrusts that rocked her entire overstuffed body.

Did it feel like she was a little too warm? Or rather, that he felt her heat with a little too much intensity?

Like her wetness was coating his bare shafts?

He kept moving, thrusting, fucking her while trying to sluggishly put two and two together. Could the condoms have broken?

Fuck. The shark tried to will his hips to stop, just to take in the situation and decide on the next step, but even that felt like an enormous effort. Pulling out of the ferret was almost unthinkable in the feverish haze of the double dose of aphrodisiacs. Like crawling out of a warm bed on a cold morning. Impossible. Each little thrust felt so good, with Sandra’s inner muscles caressing every inch of both of his cocks. It was no big deal, anyway, was it?

No, that thought was preposterous. She’d end up pregnant if the condoms didn’t hold. That’d change her life, maybe ruin it, all for a moment of pleasure, however intense it might be. And he would end up a woman. The Zebra would win! He recognized all these facts, and they swirled around in his head like leaves on a fall breeze, but they failed to register emotionally, or at least, not as important as their mating.

Sandra was begging for it. She was squealing, moaning, panting in sweet sexual bliss, and her soaking wet cunt felt like it was suckling on Shane’s twin cocks. She was completely lost, which meant that even if he didn’t want to, the shark had to be the responsible one. Where emotions failed, drowned under the raging torrent of lust, he tried to rely on raw intelligence instead. The same focus that’d saved him that one day so many months ago.

“We have to stop,” he huffed. “I think the rubber tore.”

“Nnnooo, just keep fucking me, please,” Sandra whined. She was breathing heavily, squirming as if just on the edge of orgasm.

“I c-can’t, that’s what she wants us to do, and we’ll both lose,” the shark replied, his voice such a low growl that Sandra could feel it. “I have to pull out.”

“It- it’s okay, just… you can cum inside me, it’s worth it, I don’t care, just don’t stop!” the ferret pleaded, clenching her inner muscles around Shane’s twin shafts and making him moan out.

Gods, more than anything, he wanted to do just that. If he were in any other situation, he would’ve. But not here, not now, not while that sadistic Zebra no doubt watched them struggle with malignant glee.

Shane gritted his teeth and pulled out. Or he would’ve done, if Sandra hadn’t hooked both of her legs around her hips and squeezed, pulling him back into herself. The sudden spike of panic was enough to clear Shane’s mind enough for him to realize what was going to happen.

“S-stop, I’m g-gonna- I can’t hold it!” he grunted. It felt like the cum was already rushing from his heavy balls and up his shaft, and Sandra kept wiggling to ensure it’d happen.

“No! Breed me!” she begged, a glassy-eyed lusty stare, almost manic, accompanying those fateful words. “I wanna- wanna get pregnant!”

“I d-don’t want to be a wom- f-fffuck,” Shane groaned as he came. It wasn’t as if he could do anything, at that point, not with both cocks inside the ferret’s wildly clenching warm pussy. Anyone would’ve succumbed, and he was no better.

His world went white as instincts and muscle memory took over. He thrust himself as deep into the ferret as he could, aided by her squeezing, strong legs, and prayed that the condom wasn’t actually torn.

But of course, it was. Inside her, as his cocks bucked and jerked, the first rope of cum sprayed through the broken tatters of the two condoms, both torn apart by the friction of latex on latex. Had he only used one cock he might’ve been safe. With two, he was now pumping his seed deep where nature – and his captor – had intended, into the ferret’s fertile depths, each drop splashing against her cervix with nothing either of them could do.

For all the risks they had taken and skirted without misfortune, this was one that nature hadn’t let them dodge nor escape.

Sandra moaned in dissolute ecstasy as she was seeded and then, quickly, fertilized. It didn’t matter what the consequences were, for her; only the gushing ecstasy of her loins and ultimately, her entire body, mattered. And for that blissful moment of sealing his own fate. Shane could only agree; it felt so glorious that the feeling had to be worth anything, any price that his captor would exact from him.

And so, he remained inside the ferret until his cocks had finished doing their duty, perhaps for the last time ever. Only then, as the ferret – satisfied to the point of being insensate, in a deep unconscious or perhaps dreaming state – finally went limp, her legs slackening around Shane’s hips, did he pull out and roll onto his back once again.

He had a few minutes to try to comprehend what had happened, but he didn’t, in that moment, feel any kind of urgency to get up. His whole body felt like it weighed a million tons, and each limb was still as lead. It was only when the room’s thick metal door opened that he stirred, clumsily struggling up on his feet, and in doing so, he found himself standing face to face with the Zebra-Mask Zebra.

She was holding a rifle, and the business end of it was pointed at him.

“I did tell you what’d happen, didn’t I?” she asked, and although the mask hid her face entirely, Shane could hear the smirk.

“No! I don’t- ngh!” Shane groaned as the dart struck his arm. He fell backwards just a few seconds later as the paralytic, transformative venom filled his veins. “F-fuck you, I’m… I’m still gonna-”

“No, no, you’re just gonna enjoy this,” the Zebra smirked. “Like her. See? She’s happy, despite initially thinking she didn’t want to get pregnant yet.”

She gestured towards Sandra who was still lying on the floor, apparently having fallen asleep or at least unconscious from the sheer satisfaction and pleasure of finally getting bred.

“You’ll probably get knocked up soon enough too. Can’t control those urges at all, can you? You could’ve just eaten her out and handled not getting any relief yourself. But no…” the Zebra mused. Shane couldn’t see her expression under the mask, but it sounded like she was smirking.

And then he was changing. His body seized up, everything seemingly happening at once; his muscles tensed and then relaxed in a flood of indescribable sensations as muscle definition began to melt away, even his bones filling with a dull ache as they reshaped themselves into something more feminine. Not just that; the sensation was an almost glowing one that engulfed his whole body, a softness spreading over every inch. Of course, his breasts swelled, into tender A-cups at first, and then bigger, into very feminine mounds that’d be difficult or impossible to hide, as the zebra gloated.

“Mhm, doesn’t that feel nice? Just like your friends. You should be happy I’m not putting you in heat like your friends. Turns out you’re no better than them,” the Zebra taunted him. Or her. Increasingly, though Shane’s mind remained the same, he- she felt like thinking of herself a woman felt more correct, if only to avoid the jarring mismatch between thought and feeling. She felt warm. Good, yes, but in the same way that being drunk felt good. Forced chemical happiness. Transformation euphoria that left his cocks leaking even as they slowly shrank.

The Zebra picked up the broken condoms when they were too small to stay on Shane’s cocks. “I could just knock you up with your own cum,” she laughed cruelly.

Shane squirmed. She couldn’t move much, and the pleasure radiating through her changing form was too much to fight. The moment her two proud cocks shrank into mere nubs and the transformation deepened into her, she groaned and came. It felt altogether different than any previous orgasm; something shaking, shuddering, shattering that surged through her entire body, from the tips of her fingers to the spasming and deepening slit between her legs, and her wetness gushed out so hard that Shane felt it soak her trembling legs.

The transformation was, at least, mercifully quick.

She felt empty, in a strangely desirable way. There was an immediate, instinctive desire to be filled, too; a ravenous desire to have someone stuff her full. The Zebra, chuckling as she no doubt recognized that feeling from her other victims – or perhaps from herself – leaned to press a canine dildo against Shane’s new, slick folds.

“It’s the one that knocked up your donkey friend,” she mused. “Hold on, my bad; it’s the one you knocked her up with.”

It wasn’t connected to anything. But Shane’s newfound pussy still clenched at the touch of it, as her body slowly reshaped itself into a much more feminine figure. “You know, you had a chance. In your previous test, two of you had to fail,” the Zebra told her. “You just screwed up.”

She forcefully thrust the dildo into the paralyzed shark, all the way down to the flared base. “And just like that, you’re a good little cocksleeve. Almost feels like you wanted this.”

The Zebra thrust the toy into her a few more times, and quickly, Shane – still very, very sensitive from the aphrodisiac and drugs – came again, with that weeping pussy that had taken the place of her cocks eagerly milking the zebra’s toy. She couldn’t speak, only moan incoherently, with the pleasure easily overwhelming the seething hatred that she felt for the Zebra in that moment of degradation.

“Yep, just another slut. I was hoping that you’d put up a little more resistance. You know, I’ll know when you get knocked up. Might even send flowers,” her captor laughed. “Ah, well. As much as I’d like to keep punishing you, there are other guilty souls that deserve it. Enjoy being a woman. Think of me when you spread your legs next.”

Shane mouthed the words fuck you, but the Zebra ignored her. She leaned down and stuck another needle into Shane’s neck. Within seconds, she was out cold, not having had any real chance to figure out where the Zebra’s base was – but she fell unconscious with a smirk. Her captor took that to convey pleasure, but as consciousness left Shane’s head, she was thinking of that secret trump card she had ensured she’d have, even if she lost.

When Shane woke up, she was still a woman, and at her own home. She didn’t like how things had worked out. However, it didn’t feel terrible. It was a little shameful to admit, even to herself, but she’d absolutely explore her new body a little more, later on. Maybe with a friend. Or two. But most importantly, the Zebra had, as she expected, missed her triple backups of the clip her phone had recorded, even though the phone itself had been destroyed. On that brief film, the zebra’s face was plainly visible.

It was Shane’s turn to smirk as she, after spending a few days called in sick from work, sent that clip to the police. And then, after a moment, to every news agency she could think of.

Good fucking luck hunting for victims now, asshole, she thought. She might’ve lost her masculinity, at least until she could figure out how to get it back, but she had dealt a heavy blow to her captor in turn.

Further, if there was a chemical that turned males into females, the inverse probably existed too. She’d just have to corner the Zebra individually, separately from the authorities, and force her to share it. Perhaps with a trap of her own.

Now, she just had to avoid getting pregnant. At least that part would be easy.

…right?
