Story:
Part 02
----

Finally, after days of wandering around the forest Dea, a self proclaimed botanist and alchemist, found the tree of Foedus, particular type of plant unknown to the science but a famous among legends and tales.

The Pale Tree seemed odd compared to lush flora that surrounded it, everything was blooming, thriving in this sunny weather except for Foedus. A bit disappointed to see that the plant appeared to be dead, Dea moved closer in order to examine it, perhpas there was something she could salvage. After few steps a breaking sound echoed through the forest and the very origin of it came out the tree. Excited to see that the tree wasn't all dead Dea stopped and observed. Slowly small cracks in tree's bark began to appear, and from the crevices slippy tentacles crawled out. Aimlessly writhing, they quickly began to fall to the ground under their own mass.

Dea stood there, in front of the plant, watching it closely; eventually it seemed like the tree felt her presence - the tendrils were moving at her direction, but as such slow pace that they were quite harmless, pathetic even. One of the thinner, smaller tentacles managed to get close to her face and, from what it felt like, stared at her for quite a while before eventually collapsing under Dea's paws. "Oh, you are really in a bad shame" she commented as moved on, even closer to the plant.

Eventually all the tendrils were barely crawling around Dea’s paws. Some of them trying to touch her, wrap around her legs but without any success – they were harmless.

Dea touched the plant, gentle stroking it’s dry bark “Oh you poor thing” she whispered. Being fully aware of what was causing tree’s bad condition. More importantly she knew ways that could restore the plant to its former glory.

Unlike most of the flora, Foedus doesn’t feed through photosynthesis. It isn’t predator either, despite its dangerous looking tentacles. The plant gives sympathy towards other living creature, or at least seems to and if one is willing to feed it the Foedus will generously return the favour But this one was desperate, climbing on Dea’s leg further, up her body. “Well, if you insist..!” Dea giggled, caring only slightly about tree’s attempts.

Part 04
----

Eventually one of tentacles climbed onto Dea’s chest, barely able to cling onto her. Dea reached for the tentacle and held it gently, the tree didn’t seem to resist and let her move the tendril quite freely.

She directed the tentacle down, towards her crotch. The plant must have caught the suggestion as it slowly moved the tentacle towards her pussy. Dea gasped in excitement as she felt the plant studying her body, brushing against her most sensitive spot. Seemingly the tree understood her on some level, or at least her body language. It kept moving the tentacle back and against her clit, causing Dea to moan in pleasure, the sensation was quite something.

After few minutes of this foreplay the tentacle curved a bit and easily inserted itself into the canine. Trying to support herself, Dea leaned against bark of the tree, and looked up. In between one of her moans she noticed as the tree began to blossom. “S..so it works, like in tales..!” She thought.

Part 05

According to some ancient tales, certain tribes use to live and prosper alongside the Foedus trees that provided their self proclaimed cultists with a plethora of food. However, how the symbiosis between the plant and its fanatics worked is was conveniently omitted as it's rather unpleasant for most common folk.

Once a year a young female would be chosen to "make a pact" with the plant. After weeks of celebration, the time of the ritual eventually came. While lasting for days, it was both physically and mentally draining for the chosen female but the process wasn't lethal. Honoured the female could return to her community, enjoying the everlasting glory.

The Foedus tree is rather sympathetic towards other living creatures, providing them with its leaves that are edible and surprisingly quite nutritious. However participating in the ritual leaves the female infertile for the rest of her life, but it seemed like a small price to pay for food for the whole community.

Part 06

The tree seemed alive now, it’s tentacles began moving faster but still carefully - not to hurt Dea. The canine leaned against the tree and let the plant do it’s thing while she enjoyed the sensation.

The tendril itself was covered in layer of lubricant, so it effortlessly slid in and out, however each time it moved further, deeper into her. Minute by minute the tree seemed to grow stronger. Other tentacles started to appear all around her, another was coming dangerously close to Dea’s tailhole.

Part 07
----

Relentlessly the tentacle pushed further, eventually settling inside of her, examining the canine. Once the plant made sure it was in the correct spot, the tip of the tentacle split open, releasing its "tongue" that easily moved past cervix, looking for something deeper inside.

Meanwhile the tentacle kept moving slowly, massaging the insides of Dea, sending wave after wave of pleasure. Focused on the blissful feeling she didn’t mind whatever plant’s true intentions were. Only thing she noticed was the leaves were getting plentiful and more vibrant in colour.

Part 08
----

Eventually the second tentacle penetrated her, slow and gentle at first but seeing that the canine responded rather well to this sort of stimulation, it forcefully pushed itself deeper into her.

Dea responded with a blissful moan, the tree seemed to know the exact right spots, as if it was made to please her. As the plant applied more pressure she slipped and fell on her knees but that didn’t stop the process at the slightest. Instead, each time the tentacle retreated just to shove itself back into her moments later, she pushed her butt against the tendril.

Part 09
----

Another tentacle appeared before her, as if looking for her mouth. Knowing the plant’s nature it probably intended to feed her, however the food had certain... qualities that didn’t go along with Dea’s plans. She moved away her head from the tentacle, still the plant had complete control over her body, using it as it pleased. Eventually one final thrust pushed Dea over the edge, making her scream in ecstasy as she was experiencing such an intense orgasm causing her to squirt all over the grass below.

Part 10
----

And once she came the tentacle quickly pulled itself out of her, leaving both her pussy and asshole gaping as she was trying to recover from what the plant has done to her. She rested there on the grass for a few minutes as the tentacles were slithering off her body. She thought that was the whole process, the plant was done with her, but little did she know.

Part 11
----

After a moment the tentacles stopped their retreat, remaining wrapped around her legs. The awkward stasis lasted for a good minute or two. Dea was unsure how to proceed next - to all the knowledge the plant - after being feed - should just let her go... However That wasn't the case.
With newfound strength the three grabbed her firmly, coiling it's tendrils not just her legs but her whole body. As her pussy and asshole were spread open wide once again she gasped, both because of fear and excitement.

Part 12
----

Seconds later Dea was held against the tree’s bark, tentacles grabbing her firmly and pressing closer, almost into the tree. The plant that seemed to be barely alive just minutes ago now could easily toy with adult canine; each moment more and more tentacles appeared, all slimy, lubricated in their entire lengths.

Now, that the tree found it’s feed, it wasn’t going to let it go easily. Dea’s knowledge failed her as she didn’t expect the dying tree to be so desperate – the tree tasted her and wanted so much more; and as the tree had her in the right spot, one of the tentacles was starting to poke against her pussy again, this time in to establish a much longer “connection”.

Part 13
----

With all her limbs controlled by the plant Dea was defenseless. At some point she stopped fighting - the bonds loosened a little - and watched as the plant took over her body. After one of tentacles pushed against her pussy few times it retreated and what followed was a palm sized leaf that covered Dea's crotch. At first she didn't feel much, but as seconds passed she noticed her knees getting weaker and her pussy aroused. At this point she desired plant's intimate attention and it didn't take long for the tentacle to penetrate her, effortlessly.

The tendril going in so easily and rapidly took her by surprise she didn't fight, instead, she let it go, allowing the plant to do it's part as he was rewarded with pleasure that was beyond anything she experienced before. She felt the plant constalty going deeper, inch by inch and instead of retracting and pushing in again it just pulsated, sending wave after wave of pleasure. While in normal circumstances Dea would be scared, she couldn't muster herself to protests, even if it all seemed unnatural.

Part 14a

Hours passed and Dea offered no resistance, the tree slowly pushed her inside itself, right into the gap between the parts of the bark that seemed to match the shape of canine's body perfectly. Despite the rough texture, the whole process was delightful. She felt no pain or discomfort, on the contrary, when doubts appeared in her thoughts, the tree seemed to instinctively move its tentacle and all she could do was groan with pleasure.

Too focused on pleasure, she did not realize what the tree was really trying to get from her body. Merely holding her down and bringing her to more was just a mean to an end. Indeed, a tentacle deep within her body felt the insides of the female. The tree, of course, made sure Dea couldn't feel it. Over time, however, the thread found its target and slowly crept into her ovaries. The tentacle shuddered forcing another powerful orgasm, in its own way rewarding the females for thinking "cooperation."

Part 14b
----

Knowing that Dea would be a suitable "partner," the tree tightened its bonds and extended another tentacle that swiftly wrapped around her face, - it's destiny was to provide the prisoner with food for as long as it was needed - of course, the tree's intent wasn't to kill the poor canine, however, which in the absence of intervention from other parties their symbiosis could go on for years.

While the tree freely used Dei's body - leaving the tentacle always inside her and drawing from her only when it got hungry - fruit slowly began to bloom on its branches.

Part 15
----
Days, weeks, months passed ... maybe even a year? Dea certainly couldnt feel the passage of time, intoxicated by the gas pumped into her nostril by tentacle that was wrapped around her mouth. She lived as if half asleep and only occasionally regained consciousness only to be assulted by another wave of orgasms, shortly followed another forced nap.

Over time, the branches of the tree began to bend under the weight of the fruits that profusely began covering the grass around the plant. Along with them animals began to appear that feasted abundantly. The tree did not pay attention to new potential candidates, after all, it had Dea all for itself, keeping her in state that was supposed to last for years, decades.

An exceptionally large amount of wild animals was quickly noticed by the local hunters, although the tree was far from the settlements, they ventured further and further, excited by the abundance of the forest. Although this was not Dea's goal, her "sacrifice" allowed her to feed many people.

Months passed until one morning one of the hunters encountered a rather peculiar tree. huge, wide for a few adult males, and its leaves so dense that it was impossible to judge the height. Surprised, the wolf circled the tree until he saw the female embraced by the plant. As he approached few tentacles launched themselves at him - trying to grab his legs and arms but he was too quick, effortlessly he sliced them. Moments later he was by the female, grabbing the tentacles off her.
