[Sissification, Genderswap, Chastity]

"So, this is your grand plan? Capture those that you can't kill, so you can grill them for information? That's rich, even for something like you!"

The loud voice of one Ironblood Heavy Cruiser, Deustchland, echoed out through the holding cell she had been tossed into after she was forcibly captured by the Sirens following a skirmish against them. She had been caught out of line trying to take down the fleet's leader, but being captured wasn't enough to tame her spirit. Far from it. If anything, being caught was just making her feistier. And if she had her rigging, she would've probably let the violent constructs try to eat away at them to serve as a piece of food for her.

"Still as feisty as ever." The Siren assigned to keep an eye on her, Tester Beta, giggled a little as her piercing golden eyes peered straight into the ocean-blue eyes of the Ironblood girl. "But you won't be singing to that tune for long. You'll know your place. Because you, and the rest of your kind on those seven seas... You'll learn what it means to obey. And you'll follow the specifications we've laid out for you. You will all fall, and you will be made into little more than a loyal minion of ours. Not that you haven't been one ever since you were made according to the Ironblood specifications."

Deustchland listened to the words leaving the Siren's mouth, before laughing from the depths of her heart. "Loyal minion? To somebody like you? What, do you think we'd just obey you because you and your awful friends decided to lend our country the tiniest hand? You are nothing but an asset for us. Once you cease being useful, we'll toss you aside. Even I would be tossed aside eventually to give way for somebody stronger. You're wasting your time by trying to strongarm your way into our graces, because you'll be left as nothing more than blood in the water once we've consumed all the meat off your body."

They were two directly competing personalities. The sadistic Tester and the fiercely loyal Deustchland would never be compatible, no matter what the former would try to do to get under the latter's skin. Which posed quite a problem, considering what she had been assigned to accomplish. Her main goal was to convert the Ironbloods to their cause, so that they could more appropriately serve as their main attack force. But if they all acted so ferverously loyal towards their country, they needed to take drastic measures.

Of course, the Sirens never came unprepared. Thanks to the technology at their disposal, they could keep running simulations to figure out how to deal with these shipgirls and their rebellious attitudes. And though they sacrificed a few of their ranks to carry out these simulations and experiment with the results of their alterations, they did manage to learn a few things in the process, including how to completely and utterly subvert somebody like Deustchland.

"Those are big words for a mere peon of the Ironbloods. But no matter." Tester said as she stepped closer to the bound girl, putting her hand on her chin as she lifted it ever slightly. "I would've preferred to test this new piece of equipment out on a Destroyer, rather than a Heavy Cruiser like yourself... But I'd be lying if I said I didn't want to see the results unfold. Could you imagine what would happen if this went wrong, what would happen if I broke you completely when I intend to merely subvert you and make you one of ours?"

Deustchland's response to this was to spit in the face of the pale-skinned golden-eyed Siren. "You won't win me over with words. Besides, what could you have made that could possibly break the Fatherland's spirit? If you can't convert me, you have no hope against the others." She flashed a jagged grin, thoroughly intending on resisting whatever this awful woman had in store for her.

Tester slowly wiped her cheek clean. Ah yes. She was completely and utterly justified in frying this awful girl's brain by the time that she had converted her. Not that she needed her thoughts to be anything but scattered. She was just going to act as a loyal minion... A loyal converter.

The Siren snapped her fingers, and a hole opened in the ceiling as a pink-colored torpedo barely the size of her fist landed on her palm with a soft *thud*. "This, my dear Ironblood peon, is what I've prepared for you. A little piece of equipment that'll make you think as we want you to. A piece of equipment that will make you more than agreeable with our methods, our wants, our needs... And indeed, it'll make you turn against your peers for the sake of our grand design. Something that you won't be able to refuse, once I've loaded it into your cannon."

Deustchland just laughed at the sight of the tiny thing. It didn't even seem like it had been properly armed. "If this is your idea of a joke, Siren, then I can't believe you actually have a sense of humor. You plan on equipping me with something as useless as that? Don't make me laugh! What's a tiny thing like that supposed to accomplish!?" She laughed and laughed, not at all taking the threat in front of her serious...

Tester's response to the mocking laughter coming from the girl's mouth was to simply put the equipment to the test. The bindings that kept the Heavy Cruiser pinned down forced her to spread her legs, exposing her panties and the slit hidden behind it in the process. Not that the Siren cared about the garment, merely jamming the torpedo through the fabric and into the girl's pussy, with the front end of the torpedo poking its way out of the slit.

The Heavy Cruiser let out a powerful and shrill moan as she didn't expect something like that, her cheeks quickly flushing bright red in shock. "T-The hell are you doing!? W-What exactly do you accomplish by defiling me in this manner!? Are you insane!? Are you mad!? W-Why would you do something like that!?" Her charismatic and bratty behavior melted into nothing but rage as she tried to jam her arms forward to wrap them around the Siren's throat and squeeze the life out of her right then and there. But she couldn't break free. All that she could do was tremble as the equipment integrated itself with her body.

"Please, if you want to enjoy this, I recommend that you stay calm. You don't want to blow your load too early, do you now?" The mocking voice of Tester echoed all around Deustchland as her world started to dark around her. All because of the equipment jutting out of her pussy. The annoyingly tiny thing that was on the verge of pissing her off so badly that she'd rip her arms off trying to get free. She'd tear out that woman's throat if it meant that she'd get rid of this humiliation..!

Then, a tone echoed through her mind. And she felt something tugging down below. Something powerful. Something that was trying to pull at her crotch, as if it was trying to pull everything out of her. She tried to struggle against the tugging, but all that she got out of it was the tone repeating in her mind, and an incapacitating shock of pleasure pouring through her.

Deustchland kept on struggling, kept on moaning, all while the tone pinged away her attempts to struggle. The more aroused she got, the more the torpede bonded with her on a fundamental level. It was feeding into itself. The pleasure was making her try to act out against it, but the acts against it were feeding into her pleasure. And yet despite how much she climbed up the proverbial ladder of arousal, the release that would make it all come to an end was unreachable. She couldn't... she couldn't cum...

She wanted to cum. She wanted to cum. She wanted to cum. She wanted to cum. Let her cum. Let her cum. Let her cum!

Tester giggled as she watched the desperation wash over the Ironblood girl's face. This was a much better result than she could've hoped for. Altering the parameters of the equipment used to convert a shipgirl into a loyal minion so that they craved a climax, and that only they could give it to them... It would keep them loyal and prevent them from converting them in the process. A far cry from the original tests that Purifier conducted within the simulations.

Deustchland's need to cum completely consumed her as she started drooling uncontrollably. The tone inside her mind kept ringing. She wanted it. She needed it. And she'd do anything to cum. She'd even play with her cute cock... Her... cute... cock..?

She struggled for a brief moment as she looked down at her crotch. And she finally understood what that tugging motion down below had been. Why it felt like she had to be pulled inside out. Because from her crotch, an adorably tiny pink cock drooped. Her pussy was completely gone. The only thing that remained was that pitiful looking sissy cock.

The tone rung out through her mind once more. And she could see her cock growing erect at the same time. It was... It was programmed to grow erect in tune to the rhythm of the tone. M-Maybe if she gave in and thrust her hips forward, it would let her cum? T-That seemed right, y-yeah.

Deustchland abandoned all sense of self-preservation as she tried to inch closer to her climax, using the little power in her hips to thrust forward. And at the same time, she saw something shoot out from her crotch. It wasn't cum... It was the torpedo that had been forcibly inserted into her pussy.

At that moment, she realized just how badly she had screwed up. Right before it exploded in her face, and Deustchland's existence was wiped away with one potent *SPLAT*

The Ironblood girl let out a powerful moan that was quickly muffled as her body was wrapped in its entirety. Thick pink rubber covered her from head to toe, encapsulating everything and making her look like a drone. But it wasn't done after wrapping around her. No, the torpedo had more to do. Namely by pressing against her most feminine aspects, nullifying them to make sure that she wouldn't stand out and look like a girl.

He wasn't one, after all. There were no breasts on his chest, his hips were only wide enough to deal with his secondary weapon, his fat ass, and his cock was still drooling that very same liquid that he had just fired off. He was a boy... A Sissy, in fact. Not just any Sissy either. He was Sissy Union HC245. He didn't have any designation besides that. Because he didn't need one.

Sissy Union HC245's body slowly freed itself from its rubbery prison, leaving his face completely covered by a mask adorned with his number, while the rest of his body was as pretty as a Sissy should be. A cute bikini that emphasized his cute nipples and his nullified bulge, plus a set of long rubber gloves and boots that made him all-too-slippery in combat. And yet so sticky whenever he needed to convert somebody.

It took time for a Sissy Union's 'Torpedo' to be reloaded. Until then, the Sissy Union's 'Cannon' was replaced with a squishy bulge. It would give all the pleasure that his 'Cannon' could provide, but with one of the orgasm. After all, only loyal Sissy Union units were allowed to cum. And only when they had properly converted their targets. Until then, they were only allowed to squeeze and play with their nullified bulges...

Sissy Union HC245 obediently saluted his commanding officer, the Siren that had converted him, all while squeezing his bulge. He was ready to serve. Obediently, and cutely, like the Sissy that he was.

Tester giggled, and kissed the rubber-masked Sissy's cheek. It was time to put him to good use, and see how many he could convert before he returned to the bottom of the ocean.
