It was supposed to be a simple D-rank mission.
A strange letter was sent into the admissions office, requesting that a team of chunin with good tracking skills would find a rare creature for a local friend of the Fire Daimyo.
Naturally, Team Kurenai was selected for this task.
Kiba, Shino, and Hinata moved out and scattered around the area where the creature was last spotted, but as they finally separated, several strange ninja attacked the group.
"It's a trap!" Kiba growled as Akamaru clamped onto the right arm of one of the ninja, who was about to throw a kunai at Shino's backside.
The two finished off the ninja quickly, but then they heard a scream.
"Hinata!" the young men cried as they rushed towards Hinata.
As they approached the clearing where Hinata was standing, three ninja fired letterbombs attached to kunai at the girl.
A large eruption engulfed the Hyuga heiress, sending the rougue ninja flying.
Kiba and Shino dropped down to the small crater that the ninja were all standing around. They all turned to face Kiba and Shino, swallowed, then collapsed, their mouths foaming.
"Poison pills." Shino commented. "They thought of everything."
"Hinata!" Kiba frantically cried out as Akamaru howled in despair.
Kiba, unable to grasp the obvious, sniffed around for Hinata's scent, only finding the occasional scrap of her clothing. After he finally accepted his teammate's downfall, he broke down and cried.
Even the usually emotionless Shino shed a few tears.
A pair of ANBU investigated the battle site a few days later, confirming that Hinata had, indeed, perished in the peculiar attack. Nothing else was found that might have suggested otherwise. Hinata Hyuga was listed as Killed In Action, and the entire Hyuga family, Neji included, wore black armbands until Hinata's 19th birthday, several months afterwards.

Neither Kiba nor Shino had eyes fast enough to see how one of the "letterbombs" has hit Hinata in the leg a split-second before the other projectiles detonated, causing the girl to vanish in thin air before the explosion that supposedly claimed her life erupted.
Nor did anyone note the peculiar aspect of the "ninja" who attacked her, who were actually local homeless men and women, who seemed to be possessed by some sort of mind-controlling jutsu.
Furthermore, the only other common garb that the "ninjas" wore, other than the black bodysuits, was a strange purple collar that detonated upon the wearer's demise via a small letterbomb on the back of the device.
And no one definitely didn't see Hinata's return coming...

Hinata woke up inside of a strange, black workshop, lit only by the barest amount of lighting.
"Where am I?" she asked aloud, before wincing at the pain emanating from her left ankle, where a recently sealed gash throbbed in pain.
"One of Orochimaru's many hideouts. In fact, this one was his primary laboratory." A familiar voice answered from behind Hinata.
She turned to see a familiar face. A seemingly young woman in her mid-20s with long blonde hair, brown eyes, and a small purple diamond on her forehead. She was clad in a very skimpy outfit made from what seemed to be black latex, complete with black gloves and boots, that not only enhanced her already enormous cleavage, it also revealed the ex-Hokage's vagina, which was covered in latex.
"Lady Tsunade?" Hinata was shocked at the former Hokage being in this secret laboratory. The Hokage lapsed into a coma during Pain's attack on Konohakagure and only recently awakened about six months ago, upon which she kidnapped Shizune and fled the village, never to be seen again.
Until now.
"What's going on? Why am I he-"
Tsunade clasped her latex-clad hand over Hinata's mouth.
"Shush, child. Calm down. I'll explain everything in good time."
Tsunade then slowly removed her hand from Hinata's face, but the girl managed to blurt out "Where's Shizune?" before the hand came back over Hinata's mouth.
Tsunade simply answered "She's on guard duty, which is pretty much the only thing she currently does nowadays."
She then cried "Shizune!"
A few moments later, Shizune walked into the workshop, but the Shizune that was standing next to Tsunade wasn't the Shizune Hinata remembered.
Shizune now had on a uniform similar to the one that Tsunade wore, but whereas Tsunade has on gloves and boots, Shizune's gloves and boots were part of her. In fact, her entire body was coated in the black latex-like substance, with the exception of her eyes, which were now white, colorless orbs. Due to the nature of the latex, it was hard for Hinata to discern where "uniform" ended and "skin" began. Shizune's face was an emotionless mask, and her hair was now streamlined to simply show her bangs and the curve of her hair's crop, which seemed almost helmet-like. The woman also wore a short katana made out of latex, and a dark-purple collar with a glowing symbol remarkably similar to Tsunade's seal. The new look also revealed Shizune's pussy, which was also coated in the latex-like substance.
Shizune then bowed to Tsunade.
"You called, mistress?" she asked in a monotone version of her own voice.
"Strip our guest, restrain her, gag her, then place her against the wall." Tsunade ordered harshly, then smiled. "We'll be converting her shortly."
Shizune did as she was told, first gagging the Hyuga girl to prevent her from protesting anymore, then Shizune whipped out her short sword, and expertly slashed at Hinata's clothes, slicing them to shreds, leaving the girl in only her bra and panties. Before Hinata could react, Shizune bound Hinata in latex straps produced from the latex ninja's hands, which then were placed on the nearby wall, with Hinata looking at Tsunade with a look of pure terror on her face, unable to escape her restraints, since they stretched, then constricted with her every struggle.
Tsunade then began what every villain stereotypically does when they think they are succeeding: she started a monologue.
"I know what you're thinking. Well, I don't right now, but I will once I place my collar on you. But I can see it in your eyes: What am I going to do with you?"
"I think you know the answer: I'm going to make you my slave, like I did to Shizune, and like I plan on doing with many others."
"You see, when I awakened, I found myself in a world in which I was the enemy. Danz? was about to send some of his assassins to kill me. He has branded me a traitor, and I'm now at the top of the Bingo Books."
"But Shizune cared for me in my weakened state, and we fled the village to Orochimaru's old hideouts."
"We found this one by accident, and it is here that I found one of my old friend's experiments."
She then whipped out a vial of the black latex-like substance.
"This is 'Chakratex', a latex-like substance derived from the chakra receivers Pain used to control his other bodies. It replicates itself upon contact with anything with chakra, draining the chakra from the item it covers."
"Orochimaru was trying to use this to make an immortal body, but he couldn't control the latex, and it almost consumed him."
"But I discovered that the same type of chakra used in medical jutsu can be used to 'nudge' the stuff into forming shapes, and, eventually, I learned more properties about this miraculous liquid."
"I can prompt it to send chakra from one body of the goo to another, allowing me to receive and store the chakra it drains, then I can send impulses to the masses of latex to control it like a puppet."
She then whipped out a collar similar to the one that Shizune had on her, which Hinata realized that Tsunade's belt was also similar to the collar.
"You recognize this? It was on your attackers. It acts as an amplifier, letting me manipulate the microscopic receivers from virtually anywhere. Orochimaru planned on giving this to Pain before he defected from Atastsuki."
"It also gives me the ability to enter the mind of the wearer if I have the matching master belt here, letting me have another layer of control over my slaves." She patted her belt as she said this.
"Finally, he discovered a jutsu that prevents any sort of thoughts of disobediance, effectively lobotomizing the recipient to the caster, making them slaves that will do anything for their master."
She then leaned in close to the terrified Hinata.
"Now, I'm going to free the latex binding you, letting it consume you, like it did Shizune, as Shinzune begins to cast the binding jutsu, forcing you to become my slave."
The latex bindings began to slowly ooze down Hinata's arms and up her legs, turning her hands into gloves while transforming her feet into boots. The latex not only constricted Hinata where it touched her, but it also fused with her skin, making its cold, rubbery surface part of Hinata.
"Yes, the latex will become part of you as it drains your energy." Tsunade gloated.
Hinata's arms and legs were now coated in latex, and she felt her energy slowly being sapped away as some sort of "uniform" was starting to form. The latex passed over Hinata's panties and bra, but it seemed to dissolve the material, leaving her naked.
"The latex will also absorb anything that's attached to your body, like your body hair and clothes." Tsunade explained as the latex began to tentatively prod at Hinata's labia. The latex then forced itself into Hinata, making her moan in both shock and pleasure as the material coated her insides, stopping at the cervix to form a sort of pocket inside of Hinata's now latex-coated, aroused pussy.
The latex then started to cover her breasts, but as it stopped just below the bottom of her mammaries, the latex started to overlap onto itself, building up and making her cleavage bigger. When the goo was done, Hinata's breasts had increased a full cup size.
"By the way, the latex will send special impulses to your body, fooling it into a near-death state where most of your bodily functions will cease, but the chakra I produce and transmit into your system will preserve you, keeping you alive."
Then the two waves of latex merged near her belly button, which was absorbed and simply became nonexistent.
Finally, the goo climbed up her neck and started on her face. By this time, Hinata was not only very horny, but extremely fatigued. She knelt down as her face began to solidify. Tsunade leaned in to finish taunting Hinata.
"Now, you'll be my slave, forced to do my bidding."
"But...where are you getting...all of...this...chakra?" Hinata struggled to move her jaw before the latex finished with the inside of her mouth, creating a latex-coated throat all the way to the voice box, as well as coating the inside of her nose, removing her ability to breathe.
Tsunade simply answered by sending some of the latex that formed her "bra" away, revealing several dozen diamond-shaped chakra seals, including a new one forming in an empty spot.
"From here, of course. I built up a lot of chakra while I was out, thanks to Shizune!"
As Tsunade gloated, The latex had sealed off Hinata's ears, as well as stopping short of the eyes, but then they sent a small, translucent layer across her eyes, protecting them.
The latex also moved over her hair, forming a helmet-like shell, but keeping most of the original shape intact.
With Hinata's transformation complete, Shizune cast the binding jutsu.
"Oath of Loyalty Jutsu!" Shizune cried as Hinata's expression of sexual bliss turned into a blank stare.
Tsunade motioned, and Shizune brought over a collar and a latex katana.
Shizune placed the collar around Hinata's neck, and instantly, Tsunade knew everything her new servant was thinking, which was mainly love and devotion to "Mistress Tsunade" and simple sexual arousal, which Tsunade decided to relieve later.
The katana slid into a small, barely visible slit behind Hinata's neck, allowing her easy access to her new weapon.
Tsunade commanded Hinata to rise, which she did, silently.
"Who are you?" Tsunade asked.
"I am Hinata." Hinata emotionlessly responded.
"Whom do you serve?"
"I serve Mistress Tsunade, rightful Hokage and leader of the Dark Desire Clan."
"What is my dark desire?"
"To get revenge on Danzo, the current Hokage, and to bring peace to the nations."
"And what is your dark desire?"
"To serve you loyally, no matter what the task, so that I may experience your good graces."
"Good." Tsunade grinned at Hinata's own words.
She then turned to Shizune.
"Shizune, go on watch. My newest slave needs to be broken in."
"Yes, Mistress."
Tsunade motioned, and Hinata followed, half moved by Tsunade's controls, half moved by her own desires.
Tsunade led Hinata to her chambers, and closed the door behind the slave.
