Twilight seemed to vanish from Withania’s daily life as quickly as she had arrived, leaving the earth pony to carry on pottering around her garden and selling her produce as she always had done.

It was a relief to feel normal. Granted, she was eating virtually nothing, surviving mostly on sunlight, and occasionally a pony spotted her strange pale-green mouth and gums - but that wasn’t the strangest thing in Ponyville these days, so she received no grief for it. Her dangerously alluring breath seemed to have greatly lessened since going all the way with Twilight, but only time would tell how long it would take her to cycle back around to her ‘catch stage’ where her body would be doing its best to attract prey again. At least she was aware of it now, which meant she could carefully control where she breathed while talking, and any other time, not breathe at all.

In the mid-week, a letter arrived from the princess by way of dragon fire - almost scaring Withania to death as she feared her greenhouse was about to catch alight. It read:

Dear Withania,

Many thanks for your cooperation during our little ‘experiment’. I hope you didn’t feel pressured into doing anything you were uncomfortable with, and I am most grateful for the unique experience you gave me.

I am eager to investigate further into your incredible nature, but duty calls and I must put this investigation on hold for the time being. I have every faith that you are growing accustomed to your new self and have gained better control of your ‘involuntary’ desires. That being said, if you find yourself in trouble you can always turn to either myself or another pony in the know and we can resolve more or less any predicament.

I will be in contact again once I have the free time for our next experiment. I would be most grateful if you could continue to take notes on your own findings - all of your existing work has been incredibly useful!

Your friend,

Twilight Sparkle

“I should probably be grateful to her for saving my rump when I got carried away with those pegasi,” said Withania aloud in the greenhouse. She put the letter down on her desk and shrugged on her apron, adorned with mini sheers, a trowel, and other gardening tools. “But I’m fairly sure Twilight isn’t interested in turning me back into a proper earth pony.”

Although it does seem less urgent now, she thought. What had initially seemed like a grave condition was becoming much less of a hindrance now she understood it better - and it seemed that there were no more hidden tricks to her new form to catch her by surprise now either.

Her musing was interrupted by the clink and squeak of the garden gate opening. Withania blinked and walked to the greenhouse door, and saw Rose nudging the gate shut with a head-butt.

“Hey Rose!” she called to catch the pink mare’s attention, “This is an unexpected surprise…”

“Good afternoon! Uh... I wanted to come and see if you were okay - me and the girls have been worried about you…”

“Worried?” said Withania, taken aback slightly, “I’m okay… just here, doin’ the gardening…”

Rose looked incredibly sheepish for a moment, shifting her hooves awkwardly and clearly embarrassed about what she wanted to say. “Umm… well, it’s just… last time you and I spoke, uh… things got a bit weird…”

Withania froze eyes wide open as she suddenly remembered the afternoon in the flower shop, her perfume-breath on overdrive, and Rose pinning her down...

“And then after that happened the next thing we heard was something about you heading into the Everfree Forest and not coming back out, and then Princess Twilight was looking for you, and then we heard nothing for another two days…”

“Oh… Yes. Um, let’s step inside for a moment…” replied Withania slowly, then turning to lead Rose into the bigger greenhouse. She offered Rose the chair and sat down on the crate.

“Withania I’m so sorry- I didn’t mean to jump on you like I did, I don’t know what came over me-” went on Rose, but Withania cut her off.

“No, Rose, stop a moment- it was my fault. I’ve… I’m… Something happened to me last week and it… changed me.”

Rose looked at her with a confused look on her face. Withania wasn’t sure exactly how much she wanted to reveal - it was all too embarrassing in front of long friends who she didn’t really talk about lewd things with. But Rose deserved to know the truth if she’d been guilting herself over what had happened in the shop.

“I was doing an experiment with a giant flower, and it… Well it transformed me into mostly a plant.” To illustrate her point, Withania opened her mouth to show off the pale-green interior, and then quickly closed it once it was clear that Rose had seen it. “And now I have some kind of weird plant behaviour, the most relevant of which is that at certain times my breath is a perfume of sorts that completely knocks a pony for a loop. And that was what hit you in the flower shop last week.”

Withania expected Rose to recoil in horror and disgust, but to her surprise, she didn’t. In fact, she looked alive with curiosity.

“Wooah,” replied Rose, “I knew you grew some wild stuff here, but that’s… wild.”

“Yeah, I’m sorry Rose, I didn’t mean you to get caught up in this, I’ve got a grip on things now - thanks to Princess Twilight - but last week I was out of control.”

Rose stood up from the chair and looked closely at Withania. She definitely looked like a normal earth pony, but seeing flesh that would normally be red as a washed out green was a dead giveaway that Withania was serious.

“So that’s why she was looking for you! You’re not in trouble, are you?”

“Thankfully not, which is surprising, all things considered. It turns out that Princess Twilight is uh… surprisingly open-minded to… well she’s more interested in the scientific discoveries.”

“That’s kinda relieving to hear,” said Rose thoughtfully, “And well… at least you and I have broken the ice on… you know, having fun.”

Well, that certainly explains how easily you went down on me last week, thought Withania. True, Rose had been under the influence of what was essentially an aphrodisiac, but she’d still been far too practised in her movements to have never gotten frisky before.

“So uh, do you still have that knock-out breath?” asked Rose, and almost enthusiastically leaned forward and inhaled deeply.

“No!” said Withania, surprised at her advances. Is she trying to get hit by it again? “I mean, I do, just not as bad as last week… and I kinda don’t need to breathe like a normal pony anymore, so I can just hold my breath all the time.” Rose looked almost disappointed at this, which just posed even more questions in Withania’s head. “I suppose I can probably breathe a bit of it out if you’re curious, but I’m not sure why you would be…”

Rose was holding her forehooves over her mouth, clearly trying to work up the courage to say something, but not getting the conversation where she wanted it to be. She took another deep breath, this time more to steel herself than trying to sample Withania again.

“Imagine… imagine if you could just skip to the fun part,” she said hesitantly, “And just lose all your inhibitions in an instant without being judged for it? That… was what it felt like last week. I just got this sweet smell in my nose, and suddenly I felt like you’d just told me to throw myself at you, and… and that would make you happy, and it would feel good for me…”

Withania knew that rose meant well with these words, but all she could hear was someone saying that she had brainwashed them or something. “I understand what you’re saying, Rose, and I appreciate it… but things kind of escalate further than I’ve said, and I feel like I’m taking away people’s free will-”

“Withania it’s fine,” Rose continued, cutting her off, “I liked it. I want to feel it again, and if you say it goes further then let’s go further! I want to make you happy, no interruptions…”

Withania fought with temptation, and lost. Now she knew that neither she nor her partner would come to any real harm, it was difficult to pass up another chance at the pleasures she could unlock. They were in a safe environment and both consenting - what was the harm in a little fun? She’d be lying if she denied thinking about the afternoon with Rose in the flower shop while she was in bed these past few evenings.

“When are you next working?” she asked.

“Day after tomorrow. This is my weekend.”

“Okay. But look, if it gets too weird for you, just say and I’ll stop things alright?”

“You’re doing a poor job of talking me out of this,” said Rose, placing one hoof on Withania’s muzzle to stop her. She then pressed her body up against the green mare and kissed her deeply, tongue diving straight in to find that enticingly sweet taste again.

Withania braced herself against the workbench as Rose invaded her personal space, but accepted the kiss. She held her breath, thinking it would be better to at least try and keep things under control, but her heart was racing with anticipation. Strangely, her initial reluctance had put her in a more submissive mood. Having Rose come onto her like this was thrilling, she would be quite happy to let her do the legwork, so to speak.

“Mmmmmm,” Rose moaned into Withania, “you’re delicious… come on, give me that breath, I promise I’ll be gentle this time…” Withania gently exhaled a little, watching Rose’s reaction carefully. The other mare pulled out of the kiss and drew her breath with her eyes closed, relishing the familiar scent. Unlike last time, there was no obvious change in her eyes, the clear mania that Withania was casting on others previously was absent. Was her breath less potent today, or was it because she was being more careful? “Ohhhh… it’s even better than last time. Let’s move onto the floor, I want a drink of your flower again…”

Rose wrapped her forelegs around Withania’s neck, prizing her away from the workbench as she kissed her again, and slowly lowered her onto the flagstone floor of the greenhouse, warm with the afternoon sun beating down through the glass. She then swung her hind leg over the green mare and lay atop of her, so she had free access to the sweet honeypot between Withania’s legs. Withania was presented with Rose’s moistened folds and quickly returned the favour, nuzzling her nose into the damp passage and lapping at her peeping clit. She gasped as Rose ravenously ate her out as if she had been starved for days.

This is crazy, she thought, If this is her idea of gentle, it’s a good thing I stopped her last week.

That being said, she had to admit that the slightly rough treatment was just turning her on even more. After being in the dominant position for her last few times it felt incredible to let someone ride her. Rose was breathing heavily, her breath and tongue hot against Withania’s folds as she lapped and sucked away at the sweet ooze coming out. In response, Withania couldn’t help but let out a muffled squeak, her lips pressing just a little too hard onto Rose’s bud and making her gasp at the same time.

“Mmpf, sorry!” said Withania, pulling out again, “This is just a bit more intense than I expected my day to be!”

Rose laughed, taking a breather herself. “Oh honey, I’m just getting started! We’ve got the weekend, and you keep alluding to ‘weird things’, and I want in on it!” She got up off of Withania and turned about whilst licking her lips, then interlocked her hind legs with Withania so that both of their flowers pressed together. Holding one of Withania’s hind legs up against her chest and grinding against her crotch, she pressed her forehoof into Withania’s nightshade cutie mark. Withania felt Rose’s fluids mix with her own, and just like before she could almost taste it, driving her to more pleasure.

“You’re thicker on the hips than you used to be as well,” Rose panting, pacing herself, seeing Withania’s climax building up. “Lot of pudge in only a week. What else have you been up to?”

Withania didn’t respond, she was getting close, very close - and could feel the wave starting to build inside her as Rose compressed her clit against hers. A good poker face was something Withania definitely didn’t possess, and Rose could see her racing for the finish line. She pulled back slightly, pleasuring herself with her other free forehoof, but leaving Withania laying on her back unattended.

“Nooo! I’m so close!” moaned Withania, her eyes darting up to Rose’s devious smile. She could see what the tan mare was thinking, and being left on edge like this was torturous. “Okay okay, but don’t say I didn’t warn you!”

“Yeeees?” prompted Rose, pressing their crotches together again, but holding them both still.

“The Tegmen Flower that I grew traps animals and feeds off of excess nutrients in and on their body then releases them again, which is how I ended up getting turned into a hybrid - oh stars please, Rose I’m so close…”

“Keep going!”

“Urrrgh! I’ve got the same kind of ability now, I can eat an entire pony and regrow them as a seed afterwards, and the other way around as well!”

Rose slowly started rocking her hips back and forth again, rebuilding her rhythm and getting Withania back into sync. She leaned down over Withania and kissed her, tasting her own fluids still on the green mare’s lips. “Like, whole? How? Could I do it?” she asked, teasing Withania with light kisses to her mouth and neck.

“It’s… it’s a lot easier than you’d imagine,” continued Withania between gasps, “I can tell - aaah - I can tell you more later, let’s just do this first…”

“Withania, let me eat you and I will give you the best orgasm ever. I want to try it, right now.”

Withania’s eyes shot open wide as Rose plunged in for another deep kiss involving a lot of tongue, tasting her golden sweet salvia. Her sex-addled brain was trying to make sense of how Rose could be this much of a dark horse, but her body - specifically her pussy - was screaming: Yes, we like all of those things just say yes!

“Mmmm-hmmm!” she mumbled into Rose’s mouth, nodding at the same time. Rose finished the kiss, and then pulled back, stepping off of Withania entirely. For a moment, Withania thought Rose was up to something and looked anxiously down her chest at the tan mare, but Rose had retreated to Withania’s crotch and this time assumed a proper position for oral, practically diving into Withania’s sopping flower with gusto. She put one foreleg under Withania’s hip to hold herself in place and dug her muzzle in between the honeyed folds, then used her other forehoof to stimulate Withania’s clit at the same time.

Withania lay back and bit her lip, her own forelegs spread wide as Rose performed the most spectacular oral sex she’d ever felt, reaching deep into her passage while pleasuring her button in ways only another mare would know how. Withania’s orgasm built a broke like a tsunami, her partner expertly alternating between slurps and breaths, completely able to continue her onslaught while Withania rode to cloud nine on a rocket.

Once Rose felt Withania relax from her tension, and the flow of honey-like nectar ceased, she pulled out, panting and licking her chops. “So how does this work? How do I do it?”

“Aaahh… wow…” sighed Withania, flabbergasted. “Okay start at my hind hooves, we’ll do it rump first so I can talk you through it. Make sure you catch your breath first, once you start, you have to go all the way before you run out of breath…”

She spoke tonelessly, but not unhappily, nerves and senses on overload. She wasn’t looking, but she felt Rose pick up her hind legs and felt the warm heat of a mouth around her hooves. There was a pause, and the sensation of quicked breathing up the inside of her hocks. “That’s it, now push forward, just go for it, trust me you’ll stretch…” She felt drool and Rose’s tongue just above her fetlocks, and then a slight snort of determination. Then Rose pushed forward as directed, and Withania felt the familiar sensation of her hind legs slipping into a warm, wet gullet that hugged them together, tugging and convulsing to coax more of her inside.

“That’s it, you’re doing it!” she said encouragingly, imagining the scene vicariously in her head, rather than watching Rose and making her feel self-conscious. “Now push again, this time right up to my butt, then rest, then a big swallow to get my hips down.”

Rose did as instructed, not waiting for her lungs to run out of breath, but committing to the deed. She found Withania’s thighs were already slick with a mix of her own fluids and Withania’s addictively delicious nectar, making the act easier as she went. She couldn’t believe it, but her jaws and throat kept stretching, just as Withania said they would and within moments her muzzle was at the green mare’s pussy again, only this time on the outside. She could feel Withania’s stocky, and slightly pudgy legs all the way down the front of her chest, poking into her stomach. Now she realised she could go all the way, her arousal only grew with the seemingly unreal idea of swallowing a pony whole. Her own flower ached for more attention, trickling down her thigh - she had held off from her own orgasm to speed Withania to hers, but she sensed that she would be just as well rewarded for the wait. Her tongue lapped the errant nectar matted in Withania’s coat around her crotch, but conscious of her aching lungs, she knew she had to press on. She pushed again, Withania helpfully bracing herself so that she wasn’t pushed back, and the plush green hips slipped into her engorged mouth. With a slightly painful, but immensely satisfying swallow, Withania’s entire lower body dropped through her neck and down to her swelling belly.

“Aaaaah, perfect,” said Withania, wallowing in post-orgasmic bliss mixed with the sensual feeling of being enveloped in the body of another. “Now lead back, look up and straighten yourself. I’ll thread my forelegs in, and then just let gravity do the work, I’ll slide down into your throat, and all you have to do is keep swallowing until your mouth is clear.”

Rose lifted her head up, lurching somewhat. She’d been expecting to have to lift a lot of weight, but most of Withania was already in her middle, so her centre of gravity was only slightly off. Withania deftly tucked her forelegs into Rose’s mouth, expertly pressing into her own body to avoid discomfort on Rose’s part, and with nothing holding her up, she began to slide inexorably down, Rose’s muzzle filling her vision more and more.

Rose was grateful that the hard part was over, as her lungs were starting to burn. She swallowed hard and surprised both herself and Withania slightly by gulping her friend’s head down in one go, the entire mass of the green mare plopping down into her belly with a glorp.

“Hooooooo!” she gasped, taking giant gulps of air. As her brain cleared, the sensation of being incredibly full set in, but not in the same way as though she’d overeaten. Her belly moved as Withania shuffled inside her and righted herself. She could feel another living pony rubbing and stimulating her from the inside, and it was unlike anything she’d ever dreamed of. She clambered onto her hooves and felt her huge belly wobble under her, dragging on the flagstones of the greenhouse. It felt like she was attached to it, rather than it to her.

“Withania? Oh my stars this is something else… Are you okay?” For a moment there was a stab of doubt in her mind as she remembered that she’d literally devoured her friend alive, but Withania had seemed so calm and collected. She would know what to do next, right?

“Mmmm, Rose you’re a natural…” came the muffled voice of Withania. Rose sat down again, pressing one ear down against her belly. She could hear her thumping heart, the gurgle of her belly, and other muffled noises of Withania moving inside her. “I’m fine, Rose, well… I won’t be in a minute, but that’s the best part…”

“Are you gonna digest in there? I’m not sure this was such a good idea!”

Withania could her the slight panic in her voice as it resonated all around. She pressed her hoof up against the top of the stomach, rubbing the wall where she could feel Rose’s head pressing against it. “Don’t worry I’ll be absolutely fine, just remember this; when you see the seed, plant it in the garden. Just plant the seed and everything will take care of itself!”

Rose sighed with pleasure. Withania’s reassuring words pushed the doubt away and left a gap for the sensations to flood back in. She got back up and took a few experimental steps. Walking was difficult, but possible. She wanted to find a place to settle down for a while. Withania was quite indisposed now, and her house was empty. The thrill of just waltzing in entered her mind and she set off determinedly.

Withania lay back in the pooling liquid of Rose’s belly, wriggling and letting it seep into her coat. If she got her timing right, she might be able to get a second orgasm in here before her hooves softened up beyond use, and she wanted Rose to experience the sensation of having prey get off on being digested. She felt Rose get up and start moving, her enclosure rocking and sloshing about. Judging by the motion, she could tell that they’d left the greenhouse and gone up the step in through the back door of her house.

Heh, well… my house is your house for tonight Rose… she thought to herself.

Rose passed through the kitchen and headed for the stairs. These were a task, given she was carrying the weight of two, but her own earth pony legs were up to the job. Once on the landing, she quickly located Withania’s bedroom. It wasn’t a big house, but it had its charm, and Withania’s bed with its duvet and blankets bundled up like a nest was enticing.

“Sorry if I make a bit of a mess Withania, but this seems like a fitting place to finish this off…”

Rose climbed onto the bed, the slats creaking under the weight of her belly, and suddenly realised that she had a problem. She couldn’t reach around her belly to touch herself. For a moment she despaired, but then while attempting to reach behind her back, she felt Withania’s bulk in her belly press up against the base of her crotch between her legs. She grinned, the pleasure of discovery adding to today’s other delights. She slowly began to grind her hips against her grumbling belly, the pressure just enough to press her pussy and squeeze her vaginal walls together, and after a few seconds of finding a rhythm, she was greedily humping her huge midriff, feeling her host inside her being smushed and squashed about.

Withania had no complaints, loving the sensation of being kneaded inside a belly, and was already hard at work on her clit again. She was being tossed around as if in a laundry machine, but the perks of not having to breath meant she had no problems with this either. Knowing that Rose was getting off on digesting her down in her own bedroom and on her own bed was somehow even hotter, and she quickly got herself up to steam.

Rose panted as she steadily worked her pelvis against the quickly-softening bulk under her. She could feel the lumpy limbs of Withania become soft and malleable and felt a thrill of power play. She was breaking down the other pony, turning her into mush to be absorbed as food, and getting off on it. She held her breath and wrapped her forelegs around the smooth pudgy belly as she finally hit her orgasm, translucent fluid squirting from her dripping pussy and dripping between her legs.

“Mmmmmm, good night Withania, my sweet treat!” she murmured into her stomach as she slouched down over it.

Oh it's always the ones you least expect, isn't it? And there's more to this mini-arc too, and it won't be far behind, don't worry!
