How long had she been here? Had it been only a few hours? Had it been days? Weeks? Months? Even years?

In this environment of hazy green light and darkness, she could never tell. There was no sun or moon to guide her, and even so, her sleep sessions hardly followed any sort of schedule anymore.

It was always wake up in her pod, drink from the tentacle that always stayed in her mouth when she was able to make it, serve and be serviced by the plant, and then fall asleep when it became too much to bear.

She knew she had been lasting longer and longer, though. That alone made her feel fulfilled. The longer she could serve, the more she would receive, and the more she received, the more fulfilled she felt.

At the moment, however, Twilight was simply waiting patiently in her pod for the plant to do with her what it wanted.

The last few sessions had felt different. Last time, the plant had even taken her out of her pod for the first time since she was put there, just to let her down in the pool in its center to drink her fill directly, as much as she wanted. While she really wanted the plant to fill her like it always did, she knew that there would be a time for that, and drank her fill.

This time, when she had woken up, she hadn’t felt in need of nourishment at all. Perhaps she had simply drunk enough to keep her satisfied for a few sessions. In any case, she had no way of alerting the plant to the fact that she was awake.

But that was fine. She knew it would send its tentacles eventually.

Secretly, she was a bit thankful that even the tentacle that encircled her neck wasn’t there, comforting though its presence was. It allowed her to look down at her swollen belly. Whatever was there had stayed exactly that way since it had first been implanted in her however long ago.

It didn’t seem to be growing or shrinking, or doing anything, really, but that was okay. It meant a part of the plant was with her wherever she went. Even though “wherever she went” so far only meant “within the pod and the pool of nectar.”

A sudden sucking sensation overcame her lower body, and she looked down where the two tentacles were attached to her teats. The plant had noticed she was awake, and was milking her before they began.

Not too long after she had first been placed within the pod, the tentacles that had attached themselves to her teats had started to get more out of them than just her pleasure. She theorized it might have had something to do with the thing within her womb, perhaps tricking her body into lactating, and the plant was drinking it up. Perhaps the plant survived on a mare’s milk?

The milking didn’t take long. Her teats were never that impressive in size, and the constant milking meant that they never filled to capacity or beyond, and even if they did, the only place for the milk to go was into the tentacles.

Twilight sighed contentedly as she leaned her head back against the mass of plant material behind her, closing her eyes as she focused on the suckers pulling gently at her, not yet pleasuring her like she knew they would eventually.

Her butt clenched reflexively at the thought of the new heights of pleasure the plant would send her to, squeezing the vines in her ass and vagina, even when she was sleeping and they weren’t servicing her. This left her with the feeling of fullness constantly, to the point where when the plant had taken her down to the pool, they had left and she had felt more than a little depressed without them.

Yet they never seemed to feel as though they were any looser within her than they were when they first went in. They had not grown in size, which meant that her ass and pussy, despite the stretching and pounding they received daily, were still as tight as they had been when she had first been led in here.

She felt her smile widen. It was very comforting to know that the plant’s nectar could rejuvenate its recipient this way. Her body was kept without any wear or tear, which made her wonder if it would prolong her lifespan, all so she could stay here and enjoy the plant’s embrace.

A sudden shifting down south got her attention, and she looked down, past the tentacles still draining her teats, to the tentacle within her marehood, as it seemed to be pulling out of her.

She felt a gasp catch in her throat. Had she done something wrong? Was it punishing her for something?

But even as these thoughts went through her head, the one in her ass gave a gentle thrust, almost as though it could read her mind, and was reassuring her that it still had many plans for its thrall.

Even as the tentacles milking her seemed to stop their milking ministrations and return to their usual sucking and massaging, she relaxed again as the plant made it quite clear to her that it wasn’t going anywhere.

The membrane of the pod around her shifted, once again opening up to reveal the outer cavern, where down below the pool of nectar lay, enticing other ponies that were fortunate enough to catch a whiff of the wonderful smell into coming and joining, even though as far as she was aware, it was still just her.

Or maybe not. She had not seen another pony, but that didn’t mean there were not others in other pods.

Almost apologetically, the tentacle in her anus slowly slipped out of her. As it did, the ones on her teats also let go, and the one around her horn released its grip, leaving her there, supported by the vines binding her legs to the back of the pod.

But not for long. Another couple of tentacles approached her from outside the pod, sliding behind her and curling themselves around her as the vines around her arms and legs began to loosen.

Was it going to let her bathe and drink in the pool of nectar again? Or was she going to be servicing the plant in some new way?

The new tentacles made sure to wrap themselves around her without squeezing her pregnant belly, taking care to support it as they bound her securely, before lifting her up and pulling her out.

She glanced around as she exited, trying to spot where they were headed, but with the green haze, dim light, and inability to shift far around, she had limited success. However, when the tentacles began to take her upward, she felt herself growing excited. What was in store for her today?

When she was finally able to, she managed to get a good look at the ceiling of the room, where she noticed the plant mass clinging to the top of the cavern were shifting.

In no time at all, a small passageway had been opened, and it was from this passageway that the two tentacles had descended from.

Just how big is this plant? she wondered. How far down am I?

Was there some kind of massive plant topside within the Everfree Forest that this plant culminated in?

She was lifted into the opening, the plant mass shifting again to close it behind her, and her ascent continued, bit by bit, until a short while later, she was directed sideways into another passage.

It’s like a large anthill, she thought. Passages upon passages. How many different sections does this plant have? Will I visit all of them? Are they all for service?

Another shift in plant mass got her attention and she craned her neck just in time to see a rather small round enclosure open up, in which the tentacles deposited her, the walls/floor squishing slightly under her hooves as she was set down.

As soon as she was down, the tentacles left, and the wall shifted to close off, leaving her alone in this rather small room, and giving her time to survey it.

It wasn’t perfectly round, as there were little inverted grooves that ran from the center of the bottom of the room up to a hole in the top. She reasoned that it was probably so more tentacles could enter the vine, but more interesting was that there was a similar hole in the base. Try as she might, she wasn’t able to see down inside. Whatever it was, it would reveal its purpose when it was ready.

And it turned out, “when it was ready” wasn’t too long after she was deposited.

A number of tentacles sprouted from the bottom hole, but unlike the ones within her pod, they didn’t immediately move toward her. Instead, they simply seemed to contentedly sit there, waiting for some unknown trigger.

This, of course, gave Twilight time to survey them too. There were only two of them this time, but they filled up the hole and sealed it shut due to how small the hole was. One of them seemed to have a much more pronounced sucker shape, and she wondered what its purpose was, while the other one seemed no different from the other countless tentacles within the plant.

*pip*

Twilight blinked in surprise as something dripped on her. The same sweet scent as always suddenly invaded the room, and she looked up, where the other hole seemed to be leaking some kind of liquid. A quick taste of the liquid that had landed on her head confirmed that it was, indeed, the same nectar, and quite happily, she started to lap up the dripping nectar, even as it started to increase its rate until it was a steady stream, pooling at her feet, before it started to continue to fill the room.

Even though it had long been completely disregarded, the logical part of her brain was telling her that she needed to find a way out or she would drown in the sweet heavenly sustenance, but the scent calmed her down as it always did. The plant would provide.

From some unseen slits in the ceiling of the room, two incredibly tiny tentacles slithered down toward her, only catching her attention as soon as tehy dangled in front of her muzzle.

What are these for?

They answered her thoughts by aiming themselves at her nostrils, and then pushing their way in without waiting for her to relax.

She jumped in surprise-- the tentacles weer rather cool, and the sensation was incredibly surprising-- but simply stood still and let them do what they were supposed to. She could feel the cool tentacles push deeper and deeper down her esophagus, until they branched off and seemingly entered her windpipe. Her breathing suddenly became restricted, much to her alarm, but before long, the tentacles had made their way into her lungs.

As soon as they had made it that far, the tentacles swelled, until her nostrils were completely plugged up, depriving her of the smell, which caused her heart to wrench. She loved that smell… what would the plant take it away from her? But as they swelled, air began to flow in and out of her lungs through the tentacles in her nostrils once again.

The nectar was now halfway up her thighs, and it was now that one of the other two tentacles in the room began to do their job. The normal one shifted and moved behind her, and before she could turn to see its intent, it had pushed its way into her ass, the entry made easy by her sphincter having accustomed to having a tentacle there. But unlike that tentacle, it didn’t stop once it had burrowed its way in.

It kept going, pushing further and further into her.

Twilight again felt herself quiver in excitement. It was going to use all of her! It took some time before she could feel it in her tummy, and then it began to push its way up her throat. The nectar had reached her chin by this point, and the stream of it had become almost a full deluge.

Where does it get all of this? she thought dimly as she felt her pussy start to moisten as the plant pumped the aphrodisiac into her lungs.

And with that, she felt the tentacle emerge from her throat, gently push her jaw open, and push out. And just in time, as the nectar started to cover her face. Some of it inadvertently splashed into her eye, and for a moment, she clenched it shut, thinking it could damage it, but then it turned out the nectar was harmless to it. Yet another impossibly amazing quality of the plant, it wasn’t denying her eyesight.

Once the nectar had completely submerged her, she watched the upper level of it continue to rise as it approached the very top. As it did, she felt the tentacle push even further out of her mouth, reaching toward the upper hole and causing her head to crane with it.

Just as the surface level of the nectar had reached the entry hole, the tentacle reached up and plugged it, embedding itself firmly in the ceiling, and preventing any more from entering.

It was hardly a tight seal around her mouth, but her throat was completely closed off, preventing her gag reflex from causing her to let any nectar accidentally in. But the plant wasn’t done pushing into her. More and more of it, for just a moment longer, until finally, she wasn’t forced to look directly at the ceiling. Now, she had enough tentacle to relax her neck just a bit. Her hooves had been lifted off of the ground, and she was in an upright position, suspended by the tentacle currently impaling her.

And now the other tentacle went to work. It swam over toward her mound and with the suction force of a vacuum, attached itself around her vagina, held in place by the sucker ending. Once firmly there, she felt her lips curve ever so slightly as a tentacle pushed its way into her pussy and started to thrust.

Thank-you, she thought as the plant serviced her, bringing her to orgasm in mere seconds. She screamed around the tentacle in her mouth, the tentacles in her nostrils vibrating from the effort as not a sound escaped her lips, but the plant kept going.

And in seconds more, she orgasmed yet again, and again, and again.

Finally, she was once again in the state of endless, unceasing orgasm as the bolts of energy shot up and down her spine while the plant relentlessly fucked her until she had nothing left to hold her up, and she fell limp, held up only by the tentacle within her.

And even then, the tentacle in her pussy kept going. But she noticed it seemed to be growing more erratic in its movements, as though it were a stallion preparing to orgasm.

Inside me! Please, inside me! Give it to me!

The plant heeded her silent plea, the tentacle pushing right to her cervix, swelling to plug her pussy, and ejaculating within her. With nowhere to go but in, the ejaculate, whatever it was, was forced into her womb, where much like herself in this circular chamber, it completely submerged the object within her. Her belly swelled ever so slightly with how much of the liquid was being pumped into her, and for several moments, all was right.

As the tentacle in her pussy shrank and slid out of her, however, so too did the liquid with it, and she felt a sudden twitch in the muscles of her vagina.

It… it’s coming!

Her womb was now trying to expel the thing inside of her, and unlike what she had once read about labor and birth, it didn’t seem to be particularly painful. Indeed, it only felt like it did when she had to evacuate her bowels, only in a different part of her lower abdomen.

Her thighs clenched, and she groaned in exertion as her pussy walls clamped, as though they were trying to push a cock out of her, but the thing in her womb didn’t seem to be budging one bit.

I WILL get it out! I will! The plant wants me to! I can do it!

With a great clench, she was able to get it to push out of her somewhat. It wasn’t much, but it was heartening, and she quickly continued her clenching and pushing. Maybe if she got it out as soon as she could, the plant would reward her.

With that thought to motivate her, she clenched as hard as she could, groaning with the exertion. With every last fiber of her being, she pushed.

And for half a heartbeat, it didn’t seem like it would be enough.

But then something gave, and the thing inside of her was pushed out, sliding out of her pussy and into the waiting maw of the sucker attached to her mound.

With deep breaths of the air being fed to her by the tentacles in her nose, she relaxed, reaching a hoof up to brush at her mane in the nectar, and then overcome by a moment of curiosity, feeling her tummy, which almost felt like it were made of jello from how deflated it was.

Maybe the plant had brought her here to birth the object, and then let the nectar do its restorative work, returning her to the way she was without a single stretch mark or other blemish.

Either way, for a long moment, she hung there, tired and pleased with herself, waiting on whatever was going to happen next. She reasoned the plant was probably taking the object someplace safe for whatever its purpose was, but she didn’t care. She had done her job, and hopefully, she had done it well enough.

The feeling of a tentacle sliding into her pussy again told her that, yes, she had done well enough, and a sigh of relief was released. Just like before she had managed to birth the thing, the tentacle resumed fucking her relentlessly, sending her yet again into an endless orgasm as it saw to her every need.

And after several minutes of this bliss, she felt it slow and swell again as it began to pump more and more of its ejaculate inside of her, sealing it within her by swelling as before, but unlike before there it stayed, continuing to push more and more into her. She looked down and saw her belly swell up again as it had before, before a wave of exhaustion overcame her, and she fell asleep in the plant’s embrace once more.

Author's Note

It's about goddamn time I got this out. I had the idea of giving it a bit of plot as a way of explaining how the stallion gets caught (because I do want to do that still), but I'm trying to decide if I want to keep this PWP or actually give it a bit of story.

Anyway, keep your pants dry, your dreams wet, and may flocks of pegasi wings stroke thee to thy orgasm.
