Infiltration

Over one of the roofs, Naruko was crawling on all fours, her petals were spread out above her as they collected the sun's rays heat. Vines were slippery and slithered around her limbs, Naruko squirmed within her binds. The vines and flowers were on her skin like some odd decoration. Naruko felt alive, as she moved further, crawling fast on the roof while whipping out vines to propel herself towards the next building. Naruko landed against the wall, holding her weight with her claws. Naruko looked around and noticed the lack of vegetation, instead through the windows there were pots of plants, restricted by the pots they could not grow.

{Humans with their wooden handled, steel-tipped digging tools, rip us from the ground; Our roots severed, their child buds torn from their stems. Captured and imprisoned in a big wooden box; no light, slowly dying} Echidna whispered to her.

"I can't wait for them to nurture our gardens, their musky fluids will feed our bushes and flowers," Naruko whispered as she used her leg muscles to leap onto the roof of the building. Naruko landed on her feet, exposing her chest to the sun, and feeling the energy absorbed. She arched back and felt the delicious warmth on her skin. She cupped her fair-sized boobies in her hands and gently squeezed them. The sensation only drove her sensuous mood higher. The four puffy slits on the sides of her torso began pulsing and drooling slick fluids onto the floor.

Naruko slid her hands down her smooth body, teasing the vines on the way until her fingers reached two of the four slits, spreading them wide. Naruko purred as her stamens emerged from inside her, they had their foreskin which covered their bulbous head. The bulbous glans ended with a narrow tip with a hole as wide as a pen's circumference. Naruko moaned softly as she wrapped her fingers around the upper two, and slowly began pumping her stamens. The lower two coiled around thighs, massaging her butt as they were aiming her crotch, brushing it up and down.

"No, not now..." Naruko smirked when she sensed the disappointment on her stamens. "We must go and reach the Hokage Tower..."

{Why the rush? Don't let others dictate us, our body desires to sow our seeds NOW} Echidna said when suddenly she felt dozens of small anthems fondling her breasts, releasing a dense cloud of yellow pheromones into the air. {Find humans, feed and sow our seed} The anthems playing with her breasts squeezed tightly. Underneath her undergarments, the thousands of vines collected further inside. Naruko could feel the end of the vines pressing firmly against the end of her love tunnel, the pressure light, but consistent. She could feel every single one. Her body was arched in a graceful curve, her hips tilted forward, inviting the fullness. When suddenly, they began to suck her fluids, drying her out and feeding themselves with chakra.

"Ahgg..." Naruko moaned as she fell to her knees. Naruko panted softly while her claw hands slid down. Thrusting her hips against the undergarments, even though they were draining her chakra, she desperately sought more of it.

Naruko's skin was on fire, waves of pure ecstasy were emanating throughout her body when suddenly her stamens uncoiled from her limbs and writhed the air around her. The stamens were trembling, spasmed, and pulsed, throbbing in life. The appendages were growing firmer and fuller, filling with pollen.

"Ah, why they are sucking so much of me" Naruko panted. They were drinking and feeding from her chakra. Naruko was moaning, but now it was in pain, she had not experienced this before, and all of her vines were desperate to drink every single drop of her.

{The stamens are filling up with pollen} Echidna whispered. {Follow your base instincts at all times} Echidna murmured.

Waves of electric rushes washed over her body, and her muscles clenched when the stamens spurted and shuddered before a larger much more impressive fountain of thick, hot pollen erupted outward. Naruko's body boiled and seethed in pure ecstasy while thousands of vines formed through the seeds. Vines of varying thickness sprung up and whipped at the air like they were flexing. They ranged from the thickness of her little finger to the thickness of her forearm.

"Go...!" Naruko smirked on her knees.

Thousands of vines crushed into the concrete and slithered through, breaking the structure slightly, as they moved through the walls. They slithered down, towards the roads. Others preferred to stay close to her, wrapping themselves around her naked torso, arms, and legs. The vines are covered in sharp thorns. As they wrapped around her limbs, she can feel the thorns biting into her soft flesh. One vine moved to the vicinity of Naruko's mouth, brushing its partially exposed tendril against her lip like a tickling feather. As she breathed, a gap formed between her lips, and the tendril slipped inside her mouth gently. She kissed, licked, and circled her tongue around the tip of the vine as its tendril played inside her mouth, tangling itself around the back of her tongue in delight.

"They love me..." Naruto thought, she was so pleased with them.

Her moans and pants were soft, but the mist of yellow pheromones was so dense that no one could see her. The yellow mist rose and reached the attention of a couple of Jonins in the area: Kurenai and Asuma. Both of them had some idea of what they were against, so they pulled from their pocket oxygen masks and plugged them into their mouths. Kurenai checked Asuma, and Asuma nodded back. Soon they were reaching the area.

(Months before)

Tsunade had analyzed the corpse of Misuki found a few weeks back, and the different research facilities found out the possible cause. Mizuki's body was dried out, it appeared he had been sucked out from his crotch. This is due to the several wrinkles that were around his crotch area. The wrinkles reached up to his abdomen and around his hips. When they dissected, he had several thick wounds around his torso. Medic shinobi inspected what appeared to be several seeds that had been pierced into him, which grew and consumed the calcium of his bones, gaining their strength, and then absorbed the tendons and ligaments gaining their flexibility.

When the medic inspected Mizuki's lungs, they were oversaturated with a yellow compound. The compound was absorbed and found in all of his tissues, especially in his heart. The compound was found to be highly aphrodisiac, it was not lethal if it was inhaled, but harmful if it was directly in contact with the bloodstream. This is because the compound in its pure form would interrupt the normal heart rhythm making it go wild and rapidly fast, causing it to implode inside the victim.

A second medic was inspecting the waist area where the wrinkles were, it was obvious there was an intercourse at the time of death. It was not any intercourse, this one absorbed every stamina and energy this person had left. The sudden absorption caused all the fats and carbohydrates to disappeared therefore leaving the body such in low body mass.

The team of doctors was busy analyzing the corpse when suddenly the doors open in the operating room facility, with several lamps and instruments around. One of the doctors noticed that it was Tsunade. They all stopped working on the corpse.

"So...?" Tsunade asked for an update.

"It's Echidna," Danzo said at the back, even though he had crazy and unethical experiments, in these times there were no more options.

"Echidna?" Tsunade asked. Danzo instead threw at her an old research report.

Echidna was illustrated on the papers as a large flower with four purple petals filled with thorns, from their center, it had four stamens and several anthems. Echidna was a seed that came from the goddess' womb, their mission was to preserve the nature of Elemental Nations, but as time went by humans were conquering and gaining terrain, destroying the beauty of vegetation. Echidna turned sideways.

"Aren't these just legends?"

"No, they are not, the flower always existed, but it was unknown were. Moreover, it was also unlikely the flower to be active because it needed a host, and not any host. It must be female and have the stamina for the permanent and deep covenant"

"Covenant?"

"Yes, the flower will feed from the host's chakra through lustful ways, it is so hard the host must be young and full of chakra reserves to survive. Most hosts die in hours because they cannot satisfy the flower's needs." Danzo said.

"The needs? Are you talking about...?" Tsunade said with her eyes wide open.

"Indeed, the desire for reproduction is so much not many humans can withstand it," Danzo mentioned. "Echidna needs to constantly be on heat because her organism is producing seeds constantly inside her torso," Danzo said.

"But, humans cannot have the energy to be fully at the edge all the time, the heart rate stays at higher beats per minute during intercourse," another medic added.

"Precisely why the host would need lots of energy reserves, lots of chakra reserves. The moment the heat subsides, Echidna consumes the host completely and becomes dormant," Danzo said.

"You mentioned she is producing seeds in her torso?" one of the ninjas mentioned.

"Yes, her seeds are the birthing of very vicious vines and flowers, they formed inside her, absorbing her own juices and chakra. This process takes a toll on her, she needs lots of energy and she needs to find it somewhere, therefore she releases pheromones that are very..." Danzo said.

"Aphrodisiac," Tsunade said as she looked at the compound's report from the lab.

"Precisely, the pheromones are strong, that much that even affect her. However, they are only reactive to organisms by breathing them. Most humans would be painfully on the edge, it would be quite reactive after a few breaths" Danzo explained. "That's when they fell on her grasp, she won't need to do much fighting, she will grab them, and play probably with her victims before she sucks them dry"

"You mentioned she would be a host, so is this a symbiotic relationship?" one of the medic-nin asked.

"Indeed, Echidna provides her with a pistil so seeds form inside the host, and in exchange the host's hormones and the host's fluids nourish it. The host's sexual heat creates the necessary environment for the seeds to form healthy and be driven out through the stamen." Danzo explained. "Echidna will force her presence in the host mind, darkening their thoughts, and nurturing their hatred towards anyone that does not support the cycle"

"Why don't we capture her and seclude her," Tsunade asked.

"The longer Echidna and the host have been on covenant, the more seeds they have sown, therefore even if the plants are miles away, they will all come for their mother, it won't be easy." Danzo. "She is also no longer human, she might have tricks we don't even know about"

"Poor victim," one of the medics said while analyzing the corpse. "The vines and arteries were shrunk, the wrinkles were dramatic, and it felt as if he was sucked dry, leaving only a few remains of the bones left"

(Back on the roof)

"Go, go and explore, feed..." Naruko roared at them, the vines were slithering and forming simultaneously, ensuring their nerves and ligaments were working properly before they rushed down to the narrow alley between the buildings.

In the rush of the day, humans were cutting through the alleys to reach their jobs or schools, and a couple of guys walking by were the first ones to notice the numerous dark green vines crawling from the roof. The cloud of yellow mist was hard to miss, it smelled sweet and musky and reacted quickly, the first guy moaned as his nipples grew painfully hard. He was sweating, he put his hands on the wall for support.

"What is this smell?" He wondered while the tingling spread through his chest, then his limbs…

"What are those?" His friend pointed out when the vines were coiling around the hand he had on the wall.

The other guy did not notice when the vines were crushing the soil and encircling his ankles, coiling up around his legs. His friend was going to help him but suddenly a few vines leaped in the air and winded up around his legs, making him fall. Suddenly vines slithered from the ground and grabbed their arms, pulling them against their back. They both fight to loosen from the massive grip but their wrists are held down with what feels like the weight of a thousand bricks. They tried vigorously to free their arms but the vines were too thick and powerful in their grasp.

Both soon felt their hearts pumping more and more blood throughout their bodies, more pleasure than they ever had felt in their life ripped through their brain, burning synapses. Their pants tented while they panted harder, bringing in more and more of the pheromones into their lungs. They squirmed and writhed as the vines slithered across their waists, compressing. The vines crept under their pants and up their shirts, slithering across their stomachs and chests.

Meanwhile, amidst the pleasure and pain, Naruko crawled. Moving one hand and foot over the other, she moved forward towards the edge of the roof and jumped off, landing on the alley below. Naruko landed on her feet. The both of them were no longer trying to struggle. They looked up at Naruko with eyes glazed by lust, between her purple petal wings, there was a vividly feminine, tall, mature creature with deep green skin that showed off a stunning body. Her large breasts and wide hips formed a perfect hourglass shape. Below her firm breasts, there was a leafy corset that was tightly hugging her body while connected down to a low-cut thong that hardly covered her body. Vines continued to bind her, tightly slithering and roughing on her skin.

"Ah, the hunger is unbearable," Naruko said when she moaned after thicker pheromones spilled out from her chest, the yellow mist was denser than before.

Naruko smirked and with a subtle movement of her fingers, the vines pulled them both against the wall. Naruko leaped towards the wall, using her talons she hold her weight. She humped and pushed her chest towards the first one. "I wonder what your name is..." She whispered. "Ta... kumi," he replied. Naruko leaned down to his face, kissing him passionately as the tremendous slopes of her breasts swept and slid along the contours of his chest. The several vines off Naruko's body made sure to tear the remaining clothing off Takumi's body. Takumi panicked even more when he heard her voice in his head, while her tongue was still buried in his mouth, making moans down his throat as the soft, dewy flesh of her bosom finally mashed into his bare skin.

"Can you feel it? Your body is responding, soon it will give me spurts of your life and your whole body will be given to nature," Naruko whispered when she then crossed her legs around his hips. Naruko cut the kiss, as she arched her back when then a last cloud of pheromones released. Naruko licked his face feeling his body spasming and twitching, gurgling in pleasure. Naruko felt her undergarments, twitching and exposing her.

"Ahg..." Takumi gasped.

"Sto-" Kurenai was interrupted when one vine reached up and wound itself around her foot. "What the hell?" she thought as she found herself unable to advance. "Damn" She reached down and sliced the vine with a kunai, but another vine coiled around her wrist, and yet another around her other leg. "Oh, shit," she thought. The rest of the vines swiftly rose up, snagging both arms and both legs. They wrapped around her limbs, all the way up to her shoulders and thighs, and hauled her up off the ground into the air, pulling her into a spread-eagle position.

"We have company," Naruko murmured.

"Don't... Don't leave me," Takumi said.

Naruko moaned softly as she jumped off the wall, towards the other wall. The vines were rapidly, whipping and slashing towards both shinobi. It was hard to fight. However, Asuma did his best and reached where Naruko was. However, Naruko was quite agile, she dodged his attack and kicked him on his head, throwing him away. There was not much to think, the vines were fast. He was backing away.

"Are you OK, Kurenai?" Asuma asked.

"They are so strong!" Kurenai said when the vines were only slicing up her clothing. Soon her underwear was uncovered, and then both her bra and panties suffered the same fate, falling away from her body in pieces. It took off just enough to leave her fully exposed in the front and between her legs.

"Don't worry about her" Naruko said as she was in between Asuma and Kurenai.

"Noo...!" Asuma said when he released a huge cloud of smoke, pushing away the pheromones from the alley. Suddenly, he bit his mouth and a huge cloud of fire rushed in.

The fire rushed, but when it disappeared, the vines remained. Their chakra-aloe slime protected them against the fire. In the middle, Naruko was inside her purple petals when suddenly she released hundreds of thorns. Asuma dodged most of them, and Naruko leaped towards him, stretching out her right arm when suddenly vines emerged towards him. The vines were whips that crushed the rocky pathway, when Naruko pulled the vines back, the vines coiked around her. Asuma just barely dodged them.

"Ahg," Asuma said while Naruko leaped forward, landing on all four, with her petals feeding from the sunrays. Naruko moaned softly as she leap and attacked.

Naruko reached to kick him on his head, but he dodged and aimed to hit her on her belly. However, the four stamens pushed him off a few yards from her, to the ground. Naruko was using vines to slash where he had landed, but he rolled quickly. Nevertheless, he didn't realize a small vine rushed and pulled away his oxygen mask. Asuma had to react so he backed off, but more vines pulled him closer to her. Meanwhile Kurenai could see through an orifice from all the vines holding her captive, she knew it was too late.

Naruko smirked, and rushed to where he was, landing on top of him. The four anthems were coiling around his limbs, squeezing harder. Naruko moaned softly before pheromones spilled over from her blossoms. It all happened fast, Naruko kissed him deeply and her petals enveloped all of them. Kurenai could just see the sudden movements.

"Ahg..." Kurenai managed all of the strength she had, but it was futile.

In moments, Naruko emerged from consuming Asuma, he had just become a void for vines to reproduce. Naruko crawled and swung towards Kurenai. Naruko landed in front of her. Kurenai felt her hands gently press against her belly. She moaned softly at Naruko's touch. Naruko's hands slid up her womb and softly grasped Kurenai's breasts. She gasped sharply, not expecting the woman to grab her. Lightly massaging her orbs. Naruko's vine revealed Kurenai's face again, and Naruko came closer and used her mouth to remove the mask Kurenai had, spitting it away.

"Breathe..." Naruko said as her blossom spilled out a fresh wave of pheromones.

"Ahggg...!" Kurenai did a jutsu, hiding away from the walls. Kurenai was cautiously dodging all the vines when she grabbed her oxygen mask and plugged it in. With the few rags of clothes, she managed to cover most of herself.

Kurenai was rushing towards Naruko, she saw her back and how her firm glutes were exposed. Kurenai dodged the vines stretching like spikes toward her, she dodged and bent her body. Naruko turned back, but before Kurenai could reach her, she was suddenly was trapped. Naruko smiled when the vines in her body were uncoiling and exposing her full body while she jumped to where she was. Kurenai tried not to stare at the exposed crotch. Naruko grabbed her oxygen mask but this time crushing it on her hand.

"What... What are you going to do?" Kurenai was shivering in fear.

{We want HER} Echidna loudly claimed in Naruko's mind. Echidna reached into Naruko's mind with inky, gooey, rubbery green vines of thought and was rewarded with a rush of images and sensations.

Naruko dropped on all fours, her right hand reached her dripping sex, spreading them with her slender digit. Kurenai's eyes widened as something emerged from Naruko. Naruko purred as a deep green organ slid out of her. Kurenai couldn't separate her sight from her this organ as it slowly pulsed up and down. It was a veiny organ that had its own foreskin which covered its bulbous head. The bulbous glans ended with a narrow tip with a hole as wide as a pen's circumference. The sight of the appendage sent a powerful bolt of lust through Kurenai.

"You seek purpose in life?" Naruko said

(Lemon Warning)

Kurenai was soaked, her sex crying out for something to slide deep inside and fill that terrible void. Her breasts were aching for attention too. Kurenai whimpered and rubbed her thighs together. She had to run. Something was very, very wrong. She had to run. She had to drop to her knees and-no, run! Naruko's eyes locked on her own again, and the dark-haired girl gasped in shock when a third eye opened on Naruko's forehead. It was Echidna's sight.

Unlike the others, this one was arranged vertically with black a black sclera and a golden iris. The pupil was a thin, black slit.

Kurenai began to stumble back, wobbling uncertainly as if drunk. The moment that third eye had opened she felt a strange pressure in her head, as if something was pushing against her mind.

"Don't be scared." Naruko whispered, a cheshire grin on her face. She followed her prey until the girl had backed herself up against a wall and placed a hand against it next to Kurenai's head. Naruko already had her second hand pumping her appendage. Naruko let her off her appendage and wrapped her arms around the dark-haired girl and pulled her closer until they were pressed together. The vines did the job of removing any left clothes hiding Kurenai's skin. Her bare body was entirely pressed up against the gorgeous plant girl and Naruko was so warm and her skin so soft.

In contrast with feeding, Naruko remained on her back, while the petals, slowly enclosed them. Naruko dropped on her back, while Kurenai was above her. Naruko's apendage was flexible and moved underneath Kurenai's pelvis, aiming to the prohibit entrance. Naruko's stamens coiled around Kurenai's arms reaching to her gloves. Kurenai moaned in pleasure, feeling her breasts squeezed and sucked on at the same time. The last two stamens moved and coiled around her legs, spreading them wide and flexing them at the same time.

Lastly, Naruko used her hands to guide Kurenai's head over to hers. Naruko opened her mouth, letting her thick prehensile tongue like organ extend. Taking the hint, Kurenai opened her lips and gasped as the slippery organ slid into her mouth. Tightening her lips over the thick tongue, she began sucking on it. Her eyes rolled up as she felt the Naruko's nectar leak more onto her tongue. She moaned when she felt the tongue begin to thrust on its own in her mouth, spreading the syrupy stuff all around inside her mouth. She muffled on the undulating tongue inside her mouth.

Naruko was feeding her, for what was about to happen. Suddenly her appendage plunged into Kurenai. She muffled on the undulating tongue inside her mouth as she felt the organ rapidly moving inside her. Naruko gripped Kurenai's hips and slammed her down onto her hot member. Kurenai screamed while the tongue filled her mouth. Naruko narrow tip penetrated through her cervix, allowing the Naruko to pump her directly into her womb. Kurenai's eyes widened as she felt her daughter's tongue slide down into her throat.

Kurenai gasped as her body began to glow the same shade of green as Naruko, before it began to change. Fat melted away to make room for muscles until her untrained body was suddenly very lean with well-defined biceps and abdominal muscles. Her thighs and ass both grew thicker, tingling wonderfully as they expanded and her breasts began to swell.

At the same time the petals enclosed the two, in a wet but rocking embrace.
