Part 1: The Initial Host

The night sky was dotted with numerous shimmering stars, Hinata sighing contently as she watched them from her vantage point upon a hill above Konoha. The young Shinobi woman had grown fond of her stargazing point, a place she and her recent husband, Naruto, often frequented when they were both present in the village and not out running missions. And even though Hinata was alone tonight, the ring on her finger reminded her that her love would soon return to her. It had been just over a year since the two had gotten married, Naruto's most recent assignment causing him to miss their anniversary. Though she didn't mind...he'd more than make it up to her when he got back.

Hinata gasped as she saw something hurtling through the sky; a shooting star. She stood up, watching as rather than passing by it began to speed up and descend to the ground. She stood up, quickly figuring out where it would land based on its descent angle and speed. Hinata grabbed a nearby satchel and quickly dashed into the tree line behind her, carefully watching the object as it descended, before leaping up into a tree. She then quickly moved from branch to branch, tree to tree as the object neared the ground. Then it struck, and with a thunderous howl of wind, Hinata was sent flying backwards. However, the kunoichi was able to quickly flip while airborne, landing on a solid tree trunk with her feet, her chakra allowing her to stand in the otherwise impossible position. The wind subsided as quickly as it came, Hinata remaining firm upon the trunk until it had. She then looked once more in the direction of the crash, using her Byakugan to scan for the chakra of anyone nearby. Seeing that no one had been caught in the impact, Hinata resumed her approach.

A minute or so later, she found herself standing at the edge of a crater, no more than twenty meters wide and five meters deep at its center, with a small mound of upturned soil ringing around it while broken trees and branches were scattered around the edge of the newly formed clearing. Hinata leaped atop the ring-shaped mound and looked into the crater; at its deepest point, the center, she could see a black stone, jagged and loosely shaped like a football. Hinata quickly slid down the slope of the crater to the center to get a better look; it gleamed a little as she approached and once she stood next to it she could see similarities to a gemstone. In the years following the splitting of the Moon, numerous fragments had descended to the planet...but none of them were like this. Hinata smiled, reaching down and grabbing it. It was surprisingly cool to the touch, Hinata quickly depositing it into her satchel. She turned and quickly leaped out of the crater, her feet carrying her back towards Konoha.

She'd just found the perfect anniversary present...

...

Hinata stood patiently in front of the jewelers, the sun well into it's ascent as Hinata held her satchel, a small smile on her face. A matching pair of bracelets, or perhaps some necklaces...the stone was plenty big enough for her needs with plenty left for the jeweler to turn a profit on the deal. She quickly reached into the bag to feel the gem, her finger tracing along the stone surface, the cool sensation soothing to the touch...then she felt something cold, squishy and recoiled with a gasp...just as the door opened. Hinata quickly turned to see the store assistant walking out. Hinata calmed down a bit, even if only to save face.

"Oh, Morning Mrs Uzumaki," the assistant greeted, "You can come in if you want!" Hinata nodded, quickly following the assistant into the store, dismissing her earlier experience. Once inside, she was surrounded by glass cases filled with a variety of jewels and chains made of a variety of precious stones and metals. The assistant quickly dashed behind the counter, Hinata striding forward and reaching into the satchel again. Her fingers wrapped around the stone...it was cool and smooth as before. The store owner emerged from a doorway behind the counter, smiling at Hinata.

"Good Morning, Mrs Uzumaki," he warmly began, "What can I do for you today?" Hinata quickly pulled the stone out from the satchel and placed it onto the counter. "Oh wow," the owner exclaimed, "I've never seen a diamond that large!" Hinata looked down, gasping at what she saw. The stone...it was different now. It wasn't black anymore...it was a shining white color, glittering more radiantly than anything she'd seen. "Where on Earth did you find it?" he asked.

"Th-that's the thing...It's not from Earth..." Hinata answered, at a loss. The owner nodded, studying the stone.

"A Moon Diamond, eh?" he replied, "This'll be worth a fortune! I could make the finest jewelry in the entire Land of Fire!" He looked at Hinata, his eyes gleaming with possibilities. "How much do you want for it?"

"W-well, since you're asking," Hinata answered, "I was wondering if you could make a pair of necklaces." Hinata looked up. "If you make them...you can keep the rest for whatever you want!" The owner smiled enthusiastically.

"Certainly, Mrs Uzumaki," he responded, "I'll make you the finest necklaces I've ever fashioned!" He gripped the stone tightly. "Come back in three days time," he continued, "I'll have them ready by then." Hinata nodded, bowing before turning and leaving the store. She sighed as soon as she left, her thoughts wandering to how to explain the stones change. She wasn't a scientist but she'd heard tell that some stones from space had strange properties, like changing their composition. Changing color wouldn't be that far fetched. She began to walk home, humming quietly. In three days time, she'd have the perfect gift for Naruto.

Unbeknownst to Hinata, she was bringing more than just the clothes on her back and the satchel at her side home with her...

...

Hinata sighed as she sat down on her bed, clad only in a plain cyan bra and panties, her ample bust barely contained by her nightwear. She yawned, stretching her arms back as her sense of ease built up. The strange events of the morning were a far cry from her mind, her thoughts drifting only to her fantasies of laying once more next to her beloved husband. She laid back, fantasizing about bringing him home, giving him the necklaces she'd ordered, cooking up a delicious dinner...before ripping off his clothes and then-. She blushed furiously...only to shoot awake when she heard a pot smashing in the living room. She leaped to her feet, her Byakugan activating reflexively, as her gaze turned to the living room. It was faint, but she could detect a strange source of Chakra.

She slowly walked out into the living room, palms ready to strike as she scanned the room for the intruder. Her trained ears heard a wet, sliding sound as she slowly turned to ensure she would not be attacked from behind. She had yet to determine whether she was facing a Jutsu or some kind of transformed intruder...until she stood in something wet and sticky. She looked down, her feet planted onto a strange black ooze...Hinata's eyes widening in alarm as she recognized the shade; it was the exact same as the stone when she'd found it. And the sensation...it was the same from the morning. As Hinata's mind raced with this revelation...the ooze twitched, Hinata flinching and stepping back...the ooze clinging to her foot. Now she gasped, falling back and landing on her bottom. The ooze twitched again...before quickly surging forward onto Hinata. She screamed as it quickly covered her right leg and spread to her torso...her panties ripping apart at its advance. She shrieked as she felt the cold substance running along her bare skin, her nerves tingling as it began to cling to her, almost like an invasive second layer of skin.

Hinata refocused herself, concentrating her chakra and releasing it against the substance; an altered version of the standard Genjustu counter. She had to get this...thing off of her, or at least stop it from completely overtaking her until she could get some help from Tsunade or Sakura...maybe even Shizune. The ooze retreated somewhat, reversing it's spread...before moving again, more voraciously this time as if it recognized Hinata's attempts at fighting it. She repeated the move from before, and once more the creature retreated. The ooze brushed past the opening to Hinata's pussy, her gasping in response to its cold against her nethers. The creature paused, seemingly stunned...before quickly growing and reshaping, a tendril forming and snaking around menacingly. Hinata attempted the technique a third time...but she was interrupted as the tendril dived between Hinata's legs and into her womanhood. Hinata gasped as she felt it quickly penetrating deep within her, before the main body resumed spreading.

And then the tendril slid out of Hinata's pussy before thrusting back in, withdrawing and then diving deeper again, Hinata unconsciously moaning as the tendril filled her private regions as the creature tore through her bra. The tendril continued sliding in and out as Hinata moaned, first with panic...and then with pleasure. Her hips betrayed her, instinctively responding as her lower half was completely covered save for the area around her pussy. She tried to fight, tried to focus even as the creature spread and her mind filled with images, thoughts that were not her own. Her hands reached for the tendril that even now fucked her into submission, a last ditch effort to fight as the creatures thoughts began to overcome and subsume her own. Her fingers wrapped around the tendril, attempting to pull it out of her...but one more thrust later and she came, her thoughts of resistance fading as her womanhood sprayed out her love juices. Hinata panted, her tongue hanging out as her mind filled with the creatures thoughts, the creatures drives...and they became her own. She spread her legs wider, her right hand sliding down to her pussy as her fingers spread it open wider...allowing the tendril to fuck her more freely, her left hand adding to the **** of the thrust as she bucked her hips.

The creature, a Symbiote whose kind had long been sealed within the Moon, congratulated itself on capturing a powerful host. This woman was strong true, and her mate was one of the strongest heroes of their age...as evidenced by his fight one year prior wherein the Symbiote was freed. She would make a capable host, once properly domesticated to suit the Symbiotes wishes...and then the symbiote would claim her mate for its plan. Hinata moaned dreamily as she came again, the tendril hitting her sweetest spot, her will to resist fading almost entirely. The Symbiote gloated, guiding Hinata to her feet and back into the bedroom, the Kunoichi bowing to the Alien's every whim while panting ecstatically. As she moved, the Alien reshaped and spread around her, covering her utterly as a sign of its dominance. Her hair hung freely and two large white eyes formed on her new face. Tonight, it would reshape her further to meet its desires...and then the next phase of the plan could begin...
