Tentacled Hinata

Sakura circled the ooze and its victims three times searching for a visible weakness. The best prospect was a man-sized hard green lump near the things edge. The feelers that gave the ooze its sense of touch - the only sense Sakura saw the green goo use - were missing from the lump, and that alone would give Sakura at least a few seconds advantage.
She circled one more time, careful not to look at Ino or Hinata convulsing under masses of tentacles, and began to move slowly down the surrounding hills. She kept to the trees until she was almost in shuriken range, and dropped to the grass. The ooze seemed occupied. It was pressing Ino and Hinata together and was letting something huge surge between them. Sakura drew a handful of shuriken from a pouch at her waste and took a measured step forward as she threw them.
Sakura hit the ground and the shuriken flew wild. With her face only a few inches away from the grass she could see the lattice of mucus-like threads running through it. The ooze was as large as the others she had seen, most of its mass was spread around it like a spiderweb and Sakura had fallen straight into the trap.
She pulled herself to her knees but could not stand. The tendrils were already wrapped around her hands and her knees. The green ooze was flowing quickly down the filaments and preparing to assault her. Sakura struggled: angry at her carelessness, and afraid of her fate as the sextoy of some amorphous blob, but despite her training she could not free herself from the pooling ooze.
In retrospect she should have run to Sand, found Gaara, and brought help. Stubbornness, a trait that vacillated between merit and flaw, had not served her here.
The ooze cleared Ino's mouth.
"Fuck me, fuck me, fuck me. Oh god Hinata, harder, deeper. Fuck."
Sakura was sure that the ooze wanted to mess with her head before taking her. It wanted her to know what her friends were feeling. The ooze could think, and its tendrils were extending their fine green mesh up her thighs.
Inner Sakura enjoyed the tickle and slight squeezing as they moved. Some of the tendrils were beginning to slide down into her shoes too. Inside the tight space they spread and squeezed around her socks trying to work off the nonporous obstructions - Inner Sakura liked foot massages.
Ino gave up swearing and began to scream. She was arching her back with her head flung backwords and her entire body was tight with the power of an orgasm. The thick tentacles in her ass and cunt never stopped moving. Sakura could see small tentacles tugging at Ino's piercings. She glanced toward Hinata whose slowly distending belly hinted at some greater project of the green things.
The pool around Sakura's feet was now big enough to complete cover her, but the ooze did not try that yet. It had laced its way over and through all of Sakura's clothes and was busy lightly touching or massaging every part of her. The tendrils worked her feet free of her shoes, and several others were beginning to attack her nipples. She admitted it felt almost heavenly, and with Inner Sakura agreeing there was little reason to fight it.
From the pooled ooze to round tentacles slowly took shape. Each was as thick as one of Sakura's big toes. She felt them brushing against her legs before she could angle her head to see them. When she saw them, the smaller tendrils were busy pulling apart her pants and panties. She saw, but did not feel, both tear away. On her hands and knees, she felt the tentacles thrust into her ass and pussy simultaneously. She let out a slight "Ulp" as one hit her cervix.
The tentacles wriggled inside of her for a few seconds until the one in her cunt exploded into a few dozen feelers attacking her insides. Several of the new feelers began to work on her g-spot, another slipped outside to stimulate her clit, a handful of others seethed past her cervix and through her womb to begin directly stimulating her ovaries. Her entire body went ridged from the intrusion, and combined with the gentle stimulation of the rest of her body she quickly came.
She began to try to thrust against the slimy extrusions, and the ooze humored her. The tentacles thrust into her as she thrust her ass against her and rapidly a rhythm was established. With every inward thrust she let out a little pleased groan interrupted only by the occasional orgasm, and after twenty minutes the ooze felt her ovaries give up an egg. At that instant both tentacles let out a geyser of thick green cum. It filled her belly to the brim and then the ooze and its tentacles pulled away. Sakura lay free on the ground.
She sat there panting, confused, and sated. The sky was clear and blue.

Epilogue:
Sakura saw Hinata looming over her. Her belly had shrunk back to an almost normal size, but the mindless lust oozing from her eyes betrayed less visible effects. The girl was, at least, physically free of the ooze. Hinata knelt in front of Sakura, who was still sprawled naked on the grass, and slipped her head between her legs. Sakura did not stop Hinata from darting her tongue inside Sakura's box, but when the tongue kept going her eyes opened wide in shock.
