Putting Down Roots [Shamir/Catherine Alraune TF]

[This story does not contain spoilers for any route of Fire Emblem Three Houses]

"H-hi, Catherine," Bernadetta greeted shyly as she entered the monastery's greenhouse. "I'm here now, just like you asked. You said you wanted my h-help choosing a plant?"

"Ah, Bernadetta! Thanks for coming!" Catherine flashed her usual cheery smile. "I want to give Shamir a nice carnivorous plant for our quarters, and thought you could help me pick the best one."

"Ah! I can do that!" Bernie smiled, glad that her adoration of carnivorous plants could be of help. "Why do you want a carnivorous plant specifically?"

"Well, don't tell anyone…" Catherine lowered her voice as she ensured nobody else was in earshot. "Shamir has a phobia of creepy crawlies. Mostly spiders, but other bugs too. Our room gets its fair share of the little things, and they distress her. Poor Shamir's gotten really good at managing her fear - in public, at least. But at home? Having one wake her up or otherwise startle her in the one place she lets her guard down still hurts her."

"Ohhh, I see. I can help you choose the right kind, but the monastery doesn't have any in here… as much as I wish there were…" Bernadetta mumbled to herself. "We'll need to get a merchant to find some. Well, unless… maybe we could ask Petra to bring some here from Brigid next time she goes home!"

—

A month later, Bernadetta had a handful of wonderful, carnivorous plants delivered to her thanks to Petra. The colloquial species name was "Tropical Sweetvine Pitcher Plant.” They were an odd looking plant, mainly featuring leafy funnels, but also thick vines drooping over the sides of their pots. Having a hyperfixation on carnivorous plants, Bernie of course kept a couple for herself. But as promised, she gave a pot to Catherine, who excitedly carried it home.

“Hey Shamir, it’s here!” Stepping through the door to their quarters, Catherine called out to her wife.

“Finally. Let’s get it in place right away.” Shamir said, a silver bow held tight in her grasp.

As she stepped in, Catherine saw an arrow nestled in the wall which was skewering a motionless wasp. The walls were riddled with little holes and imperfections from countless arrows shot at bugs, some larger than others, and even a few with arrowheads still lodged too firmly to pluck out.

“This one should be honoured, it was felled by the mighty Shamir’s best bow!” Catherine commented.

“My practice bow finally broke, and this was the closest one in working condition,” Shamir said as monotonously and confidently as ever, despite her evidently recent encounter with a rather large flying bug.

“Well I think you just took out our new roomie’s first meal!” Catherine said as she placed the pot on a dresser.

“Our new… roomie?” Shamir asked, unimpressed.

“Well, yeah! What else would it be?”

“Catherine, that’s a plant.”

“A plant that’s doing us a service! The least we could do is give it a name,” Catherine grinned, yanking the latest arrow from the wall. “Here you go little guy! Your first meal in the Nevrand household!” She carefully slid the wasp off the arrow, dropping it into one of its funnel-like openings.

“I hope it doesn’t expect all its meals to be hand-delivered to it like this.”

“Bernadetta says its spouts hold a sweet-smelling liquid that draws bugs in, so I trust that ol’ Cassander here will work just fine!”

“...You’re naming it your deadname?” Shamir said, genuinely shocked.

“Just as long as nobody precedes its name with ‘Thunderbolt,’ it’ll be fine,” Catherine said with a forced smile.

“Honey…” Shamir’s tone lifted as she placed a hand on her wife’s shoulder. “You’re doing this for a reason, but I can’t think of what it could be. Want to talk about it?”

Catherine sighed. “I just thought… If I named it that, maybe I could get used to hearing it a bit more. Maybe, next time someone says my deadname, I’ll think of the plant. You know, instead of my mind jumping to other memories…” Catherine looked long and hard at the plant. “It’d be nice for this mental image to come to mind when I hear my deadname. It’s an adorable little plant! I can see why Bernadetta has such a fondness for them.”

“Cute? Really?” Shamir almost let out a giggle.

“What, you don’t think this is just the most adorable thing ever?” Catherine smirked.

“Not when you’re standing right next to it~” Shamir flirted, interlocking her fingers between Catherine’s as she pecked her wife on her blushing cheek.

—

The next day, while Catherine was on duty, Shamir took a seat in front of Cassander and simply observed it for a while. The rays of sunlight peering through the nearest window pierced through the plant’s leaves, giving the illusion that it was glowing a brilliant jade green. She could see the darker parts of its spouts where it was filled with its sweet, alluring juices. Its chonky lil’ vines flowed out and over the edges of the pot, the longest of which rested on the wooden surface below.

“Maybe Catherine was right… you are a cute one in your own right, aren’t you?”

Shamir, of course, got no response.

“Don’t tell Catherine I said that or I’ll never hear the end of it.”

The plant made no promises.

Idly feeling one of Cassander’s soft, almost fuzzy vines between her index finger and thumb, Shamir noticed a light warmth spread across her hand. Instinctually pulling away her arm, the heat disappeared after a moment. Curiosity, however, got the better of her as she again allowed her skin to brush up against the comforting surface of the vine. The warmth again appeared, but this time Shamir didn’t withdraw. The intrigued woman felt a bond of sorts form between herself and Cassander.

“Huh…” She exhaled, her interest piqued.

As odd as it seemed, Shamir felt that a channel had opened up for her to communicate with the pitcher plant. Both woman and plant allowed each other into their hearts, beginning what was possibly the strangest conversation of Shamir’s life. No words were exchanged, as none were required: each of them could feel the other’s thoughts and desires.

The first shared thought was that of mutual appreciation: Shamir was glad Cassander was there to eliminate pests, and Cassander was happy to be in a place where it could experience many new meals.

The second shared thought was even stranger: Cassander expressed that it could give Shamir a new, floral lease on life if she so desired. It gave Shamir all the knowledge she needed to make a decision, and Shamir accepted.

Withdrawing her hand and ending their link, Shamir wondered why she had accepted the plant’s offer. She wasn’t regretting her decision, but she found it curious that she decided so swiftly to transform into a plant woman. The war was over and she was happily married, yet there was a certain appeal to the life of being a simple little plant… Of being Catherine’s simple little plant.

The warm sun outside never felt as good as it did when Shamir set foot out in the nearest courtyard. After slipping off her boots, she allowed the soft grass to graze her feet with each step. She hadn't allowed herself this simple pleasure since childhood out of fear of being seen as childish. But now, her worries melted away as she felt the gentle blades of grass tickle the arches of her feet and slide between her toes.

She found a bare patch of earth for her to settle on, then planted her toes into the squishy soil. She was ready.

Shamir let the transformation begin, and immediately felt her feet begin to warp and reshape themselves. The cool earth relaxed her nerves as the inexplicable - but not unpleasant - sensations spread deeper into the ground, proving that she really was sprouting roots. Where her feet once were, there now was a small, but growing, basin formed by thick plant matter.

"Woah…" Shamir said breathlessly. "This is… This is strange. I can feel a… bowl? …growing at my feet…"

Green colouration gradually spread further up her legs, making soft, vine-like material from flesh and bone. Her balance momentarily faltered as her body felt as wobbly as jello, but regained composure before she had the chance to fall. It fortunately took only a split second for her motor functions to catch up and adjust to the transformation as it progressed through her body.

As green reached her nether regions, Shamir felt the overwhelming desire to strip out of her clothes, reveal as much skin as possible, and soak in the divine and welcome sunlight. Off came her rather short coat, her silver-adorned choker, her leather gloves, her form-fitting top, and her plain black bra. Realising she could no longer slide out of her tight leather pants, Shamir pulled a utility knife from her belt and sliced open each pant leg. She then cut free her little black panties, finally rid of her favourite outfit.

Looking upon herself, she watched as her pubes shifted from a thin bed of blue hair to a single dark green, star-shaped leaf. Underneath, her pussy was much greener than it was before, and almost twice as sensitive! The slightest breeze over her clitoris made her shiver in excitement.

Shamir imagined Catherine would be quite pleased with how much softer her body was now. Oh how Shamir enjoyed being Catherine's own little thing to cuddle and hold so close - and having Catherine as her play thing, too. Shamir was hit with the strongest urge to wrap her vines around her wife as they embraced, folding her leaves up and around them both to protect them in a secure bulb… despite not having vines or leaves of her own quite yet.

Where she once had feet, Shamir found a still-expanding basin which was filling up with gooey green nectar. At the edge of the basin, giant person-sized leaves sprouted and drooped gracefully in a circle around the transforming woman. Shamir experimented, mentally commanding one of said leaves to wave as if fluttering in the breeze. To her surprise, the leaf not only did precisely as she instructed, but it felt as natural to her as moving an arm or a leg. Her giant petals created even more surface area for her body to absorb the magnificent energy from the sun, sending warm ripples throughout her body: from the tips of her fingers to the ends of her roots; from the top of her head to points on her leaves; from the tips of her vines to the-

“Wait, vines? Already?” Shamir exclaimed, taken off-guard by the fact her vines materialised without drawing her attention. She had been expecting vines thanks to the information planted in her mind by Cassander, but she had expected a much less subtle transformation process.

By the time her attention returned to the more humanoid part of her being, Shamir noticed that her entire body from the shoulders down was green and plant-like. Her now-viridian nipples had gained the same boost in sensitivity as her clitty, feeling the air’s gentle touch and the sun’s warm light with distinct clarity. At that moment, her cute little tiddies rapidly gained weight as their form stretched out larger and larger. Her nipples began to leak out the same sticky nectar which was slowly rising at her legs. Fondling her own breasts felt better than it ever had before, turning her on in an unfamiliarly powerful way. Unsurprisingly to her at this point, her now-wet pussy was also dripping with nectar, slowly running down her legs and joining the rest of the goo pooling below.

As her head joined the rest of her planty body in its now-green hue, Shamir explored the new additions to her form: she could feel the nectar submerging her legs from the shins down as if it was connected to her nervous system; her vines had sprouted from the bottom of her legs, growing out from the nectar and articulating much like tentacles on an octopus; her giant leaves felt stronger and thicker than any she had ever seen before, yet remained incredibly lightweight; and finally, her roots began to extract the earth around her of its moisture, providing a refreshing sensation as if she had just taken a sip of the cleanest spring water. A strand of her blue hair drooped over her eye, showing that the transformation had spared a little colour for her besides just green. Her body emanated a sweet aroma, not unlike that of Cassander, yet definitely distinctly her own. Shamir hoped Catherine would like her natural perfume… Well, she hoped Catherine would like all of her new planty personhood, for that matter. One thought sizzled in the back of her mind: if only Catherine doted over her as much as she had with Cassander, then she would be a very happy plant indeed.

But it was too late to second-guess herself. She was an Alraune now, and quite a stunning one at that. Deep down she knew that Catherine loved her regardless of her outward appearance, but her doubtful tendency still reared its ugly head, as per usual.

All she could do while waiting for her wife was sit back (or rather, keep standing up) and enjoy the sunlight.

[Main Ending]

Catherine walked through the stone brick halls of the monastery towards her quarters after a day of guard duty. Turning a corner, she anticipated the same old empty courtyard which she passed through every day, but instead found a sight she would have never expected.

“Hey honey!” Shamir greeted warmly, her fibrous skin practically glowing in the golden hour sunlight.

“Sh-Shamir!? What on Earth-!?” Catherine gaped, rushing to her wife’s side.

“It’s alright Catherine, don’t worry. I’m just a plant now.”

“I can see that…”

“I chose this, it’s alright. I touched our new houseplant, and we… connected. It’s conscious! And it’s magical!” Shamir was unreservedly joyous, a side of her that even Catherine rarely witnessed first hand.

Catherine studied her partner’s new - and quite naked - body. It was evident how pleased she was with her new form. “Darling, you’re gorgeous… And happy! You seem so happy, and that makes me happy!” A tear ran down her cheek, and she extended her arms inviting a hug.

Shamir gladly accepted, holding Catherine in a tight, loving embrace.

“Shamir, are you controlling these vines?” Catherine asked, eying the tentacle-like appendages coiling around all different parts of her body.

“Oh!” Shamir quickly withdrew. “I’m so sorry honey! I didn’t even realise I was doing that… they just feel so natural to me already.”

“It’s alright, I actually enjoyed being wrapped up in you~” Catherine winked. “I’m just surprised you can control them, that’s all.”

“Well then how about you step in here so I can wrap you up properly?~” Shamir playfully bit her lip.

Seeing Shamir’s clothes in a pile on the ground, Catherine followed suit, stripping out of her protective gear. She slid a foot in her wife’s basin of warm goop, then another. Now face to face with her lover, she gently shut her eyes and leaned in for a smooch. Shamir swung her arms over Catherine’s shoulders, holding her close as they shared a loving kiss.

The person-sized leaves at Shamir's base erected themselves, stretching up as they encapsulated the pair in a hollow bulb. Sunlight filtered through the bright green walls around them, giving everything a greener hue.

"There, now we have some privacy~" Shamir said. Her voice dropped to a whisper: "What if I held you here as my prisoner?"

"What kind of prisoner would I be, willingly submitting to your captivity?~" Catherine whispered back, garnering a sarcastic glare in response. "I mean, 'oh no, this incredibly sexy plant lady has ensnared me in her vines! What ever shall I do?~'" She said coyly.

Shamir coiled her vines around her prey’s ankles and wrists, pulling them taut. Yet more vines tangled themselves around her waist, torso, chest, and neck, securing her comfortably in place. Catherine was completely under Shamir’s control, right where she adored being.

“What an incredible specimen that’s stumbled into my grasp~” Shamir grinned as she placed a hand on Catherine’s face, and another on her hip. Pressing her naked body against her lover’s, Shamir felt Catherine’s cock rise between her legs.

Shifting her stance, Shamir nuzzled her wife’s neck and made gentle love bites as she slid her hands up and down her back. She pressed her thighs together, gently squeezing her partner’s hot, familiar phallus.

“I love you, Shamir… Oh! Ahhh… You feel so wonderful… never let go darling, please…” Catherine rasped as she let her body’s movements match those of her alraune captor.  “I need you…”

“Don’t worry my sweet little thing, you’re not going anywhere…” Shamir breathed between kisses she placed on Catherine’s warm body. “How about I give something for your mouth to do, hmm?~”

A vine arose to Catherine’s blushing face, gently sweeping across one cheek before lingering over her lips. Catherine kissed the sweet tentacle, then let it slide into her salivating mouth.

Shamir gradually worked downwards, kissing her partner’s neck, then her chest, then her right breast, and finally her nipple. She kept one hand rubbing Catherine’s back while using the other to fondle her left tiddy. The plant girl could tell her wife was pleased by the increase in muffled moans she let out.

Eventually, Shamir noticed something unexpected: Catherine’s nipple was seeping nectar! She immediately released her grasp and withdrew all her vines. Looking at her legs, she could see that her wife was also becoming a plant! “Oh gods, Catherine, you’re becoming a plant too! I can feel your roots joining with mine! I didn’t even realise I was converting you!”

“That’s wonderful!” Catherine smiled wider than she ever had before.

“Wait, really? You’re ok with this? We can stop if you want to reverse this-”

“Shamir.” Catherine interrupted her panicking wife. “I want this. Breathe a second, and you’ll feel it. I can already feel parts of you, including… your desire to be joined to me like this, forever…” Catherine blushed. “Soon, you’ll feel me too. You’ll feel that I desire the same~”

“R-really?” Shamir stuttered.

“Of course,” Catherine whispered. “We can share in each other’s pleasure, now and forever. There’s nothing more I want in life than that.”

“Oh Catherine~” Shamir cooed lovingly. “I want that too…”

Changing her tone from sincere back to playful, Catherine subtly held out her arms. “‘Oh my! The plant lady’s grasp has faltered! If she’s not careful, her play thing could escape~”

“Mmm, we wouldn’t want that now, would we?~” Shamir picked up where she left off, subduing her willing captive with her vines and returning her attention to the lactating boobs in front of her. Without thinking, each of her vines that weren’t already preoccupied with another task began dipping into the pool of nectar below and lathering it over Catherine’s body.

Every inch of skin the goo touched instantly converted to plant matter, increasing in sensitivity and relishing the pleasant heat created in the process.

Shamir once again migrated her kisses down Catherine’s body, kissing her underboob, then her soft, ticklish tummy, then her waist, then her pubes, and finally the tip of her twitching girlcock. She began with gentle little pecks, but her kisses slowed to let them both savour the stimulation to their erogenous zones. Shamir grabbed her wife’s wonderfully soft glutes, pulling her closer as she slid her wife’s beautiful dick into her mouth. Sweet, gooey precum commanded her attention as she slid her tongue over Catherine’s welcome, familiar member: Already she was leaking nectar just like Shamir.

The pair felt each other grow closer in body and mind as they gradually became two parts of the same plant. They could both feel each other’s thoughts and emotions clearly now, and even communicate without making a sound. Catherine felt Shamir’s body as if it were her own, and vice versa: Shamir felt the sensation of having a cock, let alone having a cock sucked off; and Catherine felt her own ass through her partner’s soft hands. They were both figuratively and literally sharing in each other’s pleasure.

‘I adore you, Shamir,’ Catherine communicated through shared thought, her mouth preoccupied with a vine. ‘I love you so much- ah!- I love you my beautiful thing~’

‘I love you too~’ Shamir thought back, her mouth also too full to speak normally.

‘I can control our vines now too, darling~’ Catherine responded, brushing a couple freshly-grown vines against Shamir’s pussy lips. After Shamir mentally signalled her consent, the newly assimilated plant woman gently slid a vine past Shamir’s sopping labia as she used another to service her lover’s clitty.

Both women were experiencing brand new sensations: Catherine enjoyed the feeling of having a pussy, while Shamir basked in the sensation of having a throbbing member approaching its bursting point. One immediate benefit they could both sense was that they’d always climax together at the same time from now on.

‘Honey, I’m gonna cum!’ Catherine expressed reflexively despite no longer needing to do so.

Shamir experienced her first ejaculation, while Catherine got to feel a clitoral orgasm and the sensations of warm, nectary cum flooding her mouth.

Both women collapsed in exhaustion, falling to their knees and embracing each other.

“I’m so glad we’re together like this Shamir,” Catherine breathed.

“So am I,” Shamir added, gently squeezing her wife’s hand with her own. “I love you. We’ll be together forever~”

[Alternate Ending]

Catherine walked through the stone brick halls of the monastery towards her quarters after a day of guard duty. Turning a corner, she anticipated the same old empty courtyard which she passed through every day, and at a glance, it was precisely that.

“Hey honey!” Shamir greeted warmly, her voice barely audible.

“Shamir?” Catherine called, unsure where her partner’s voice was coming from.

“Down here! In the courtyard!”

Soon enough, Catherine spotted her: a little potted plant with a humanoid form sprouting out among vines and petals - a miniature little alraune! “Shamir!?” Rushing over and kneeling before her shrunken wife, Catherine was left agape.

“It’s alright Catherine, don’t worry. I’m just a plant now.”

“You’re also tiny…” Catherine figured the humanoid part of her body must have been around fifteen centimetres tall, at most.

“I chose this, it’s alright. I touched our new houseplant, and we… connected. It’s conscious! And it’s magical!” Shamir was unreservedly joyous, a side of her that even Catherine rarely witnessed first hand. “I turned into a plant, and then I shrunk down like this! Now I can be your other little plant to take care of!”

Catherine studied her partner’s new - and quite naked - body. It was evident how pleased she was with her new compact form. “Darling, you’re gorgeous… And happy! You seem so happy, and that makes me happy!” A tear ran down her cheek.

“Come on, let’s get you back home~”

—

Catherine set Shamir's pot on their bedside table, then began to undress herself after a long day’s work.

"C-cock…" Shamir droned, watching as Catherine's brilliant member broke free from its panty prison. "Dick… Catherine, I need your dick…"

"You alright honey?" Her wife asked, noticing the unusual entranced tone in her voice.

"I'm still ch-changing…" Shamir's back arched as another transformation began. "Feel… weird… Feel so… empty…" The potted plant girl unwittingly stretched out her arms, trying desperately to grab hold of Catherine's alluring meat despite being well out of reach.

“Honey? Are you sure you’re alright?” Catherine asked worriedly.

“Y-yeah, just transforming again…” Shamir was drooling at the sight of the magnificent, beautiful dick before her. It was growing increasingly difficult to think clearly as the idea of sucking cock overtook her mind. “Cock… C-Catherine, please let me suck you off… Need… cock…”

Her body began to convulse as the humanoid portion of her body began to lose the features that made it humanoid in the first place: Shamir’s legs fused together as her pussy disappeared, leaving her a stalk with breasts instead of a torso; her arms flattened out and lengthened into twin little leaves on opposite sides of her stalk; her head inflated as her eyes and nose sealed over; and finally her lips puffed up as her mouth lost its teeth and stretched outwards into a long spout.

“Sh-Shamir!? Shamir! What-!?” Catherine stuttered, but soon lost her train of thought. A sickly sweet scent reached her nose, grabbing her attention quite effectively. Shamir, now a succplant, was releasing a captivating aphrodisiacal pheromone.

Shamir’s mind finally broke, succumbing to newfound instincts and obsessing over phalluses - or, specifically, her wife’s phallus. Despite no longer possessing sight, smell, or hearing senses, she now had a secret sense that detected when a suckable dick was nearby. ‘Dick! Cock! Dong!’ Her mind rang out as she instinctually leaned towards her prey’s genitals.

“Nnng… Sh-Shamir, you make for a hell of a sexy plant…” Catherine was standing at attention, deeply aroused by her intoxicating succplant wife. “Come here, darling, Catherine needs you…” The entranced woman grabbed the potted succplant and sat on her bed, allowing Shamir’s needy mouth to all but pounce on her prick. “Ah! Mmm! Nnng! Muh-more!”

Shamir’s smooth mouth tightened around Catherine’s entire length, sucking and squeezing to the same rhythm as the cock’s pulses. Her mouth was salivating with sweet nectar, which seeped into Catherine’s firm cock, strengthening her muscles and boosting her sensitivity. The more nectar entered her system, the more Catherine wanted the keep fucking her plant wife like this endlessly. She was displeased to feel her climax rapidly approaching, wishing it could last forever.

“I’m gonna c-cum!” Shamir moaned just before splurting her load into the horny plant that had attached herself to her member.

To her astonishment, her climax didn’t end. The nectar was bolstering her fortitude and locking her in perpetual orgasm. Wave after wave of hot girlcum rushed out of her and into Shamir, quelling her infinite hunger for dick, cum, and love.

“AH! AH! AH! NNNG! MMM! AH!” Catherine was incapable of forming words, let alone sentences. The most intense and exhilarating orgasm of her life was now a permanent feature of her existence.

But Shamir hadn’t finished transforming yet. Her vines reached out to Catherine’s pulsing body and wrapped around her waist and thighs. She then severed her stalk from her roots, lifting herself out of the pot and holding herself in place at Catherine’s nether region. One of her vines pressed into her wife’s tailbone, merging up into her spine and intertwining their nervous systems. Catherine could now feel her own cock from the nerves in Shamir’s busy mouth, further solidifying her eternal bliss. Shamir’s stalk, leaves, and vines then pressed firmly against Catherine’s skin, transforming into a pair of panties made of tightly secured plant matter. Shamir retained her succplant head underneath the exterior, continually sucking off the permanently-erect cock she was sealing away.

—

Lucky for Catherine, she was scheduled for two consecutive days off after the transformative events with her wife. She had had time to grow accustomed to her new existence, and could now maintain her composure. From that day on, however, everyone around her sensed that something had changed - and not just from the bulge permanently fixed under her clothes. Shamir was nowhere to be found, but that didn’t matter to either of them. All they wanted now was to acquire more of plants like Cassander to give to everyone and spread the pleasure around the monastery~
