"You sure you wanna head down there right now...?" Polaris asked, rubbing his snout as he looked across his desk to the princess.
The purple snout in front of him only scrunched even further, and she fluttered her wings as she said "Yes! I'm fine! Doing research into a never-before-seen species of pony is something worth ignoring some issues for, okay?"
"Twilight, I know you're in heat" he said with a faint smirk.
The princess began to turn even redder, but she shrugged as she said "I know, I've studied your magic enough to know that..."
The blue unicorn chuckled, but then he shrugged, saying, "But go ahead, just, be aware that Tenti is gonna smell the heat too..."
"I will!" She squeaked, her scrunch half traded for a smile as she quickly darted back out of the room.
Polaris waited for her to be out of earshot before he looked to his daughter, saying, "Yeah, she's..."
The AI giggled, saying, "Oh yeah, she's after an egg".
✩｡:*•.──────────.•*:｡✩
"Oh, Twilight! Hi again~!" cooed the melodic voice of the plantling queen, as she stood up from her loaf position to trot over to the princess and give her a tight hug.
"Y-Yeah!" Twilight squeaked meekly, hugging the bug in return. The queen's tentacles joined in on the hug like usual, and Twilight tried her best not to shiver too much as she felt them.
Tenti was an odd mare, an odd Queen. Centuries ago, a forgotten cult of ponies had used their magic to combine a captured changeling drone together with a Tentilus plant, producing Tenti, who was then sealed away in a crystal until the day Polaris discovered her.
The poor bug spent her time struggling to keep her energy up, as she needed not just love, but also water and sunlight, the last of which she could only soak in through the tentacles sprouting from her back. One of which, by the way, was tipped with a cock, just like the one between her legs.
For some reason, Polaris and Tenti were secretive as to how they began searching for ways to help Tenti. Regardless of the why, Twilight knew the how; the changeling gathered as much love as she could, before sealing herself into a cocoon with Polaris' help, inside of which her body was metamorphosised into what Twilight knew her as.
The queen was nearly the size of Chrysalis, but her body was less skinny and more curved. The tips of her hooves, snout, ears, and even her cock were all the same dark gray that could be found on other changelings, however all of her limbs had a gradient from that dark gray to a bright green, her body now comprised of some sort of softer, more plantlike chitin that was able to absorb sunlight while still being as strong as a changeling queen.
Now, her tentacles looked like they belonged on her body. The holes in her limbs had been filled, and most importantly, her eggs had become fertile. Tenti had been able to lay eggs before, but it wasn't until after the changes that they began to hatch.
And learning how they worked was oh-so-intriguing to Twilight.
Thankfully, Tenti seemed to be avoiding the issue at hand as she talked to Twilight. The two had become friends over time, and Twilight's research sessions had become less and less formal over time. By this point, she found herself laying on Tenti's soft goo-bed, right there in her private chambers, with the bug laid down right next to her on the bed, while they talked about how her eggs worked as if they were two school-fillies gossiping about their day.
Of course, Tenti couldn't just ignore it forever. As she explained to Twilight how she created the eggs, how they felt inside of her, and how she only laid one egg- one big egg- at a time... Twilight grew more and more aroused.
If asked, Twilight would assume that she was hiding it pretty well. Her hind legs were clenched together, with her tail pinned against her rear... sure, she could feel her arousal forming a puddle beneath herself, but Tenti didn't seem to notice, right?
Oh, but she did. By the time Tenti was approaching the time to describe the actual process of breeding an egg into a mare, the queen's cock was rock-hard and throbbing beneath herself, trapped between her belly and the softness of her goo-bed.
"S-So, I... I guess you just... seduce mares, then...?" Twilight meekly asked, as her magic held a pencil aloft above her notepad. It was half-filled with her meticulous notes, something that not even Estrus would be able to interrupt.
Finally, Tenti decided to broach the subject. "Okay, Twi... I... I could try to explain it to you, but it's not easy..." She watched as the princess' ears began to fall, and Tenti slowly snuggled closer to the princess, tendrils lazily curling around her in a loose hug as she 'innocently' nuzzled Twi's neck. "But..." she whispered, her voice faint as she brought her snout close to the purple mare's ear. "How about I simply breed a big, soft, fertile egg into you, and fix that nasty heat of yours that's filling the air in my hive...~?"
Twilight choked on her words as she sputtered for a moment, her cheeks turning a hot red as her ears flopped down. "T-Tenti! I... b-but I... w-we can't just...!"
Tenti let out a faint whine, and she lifted one of her hind legs, partially moving herself overtop of Twilight as she snuggled even closer to her. The mare shivered below her as Tenti's throbbing cock pressed firmly against her flank, making the princess bite her lip for a few moments as she felt her needy marehood wink. "P-Please, it's so hard to ignore..." Tenti said, her voice starting to shake a little.
Twilight's hesitations weren't going away, but... Tenti was her friend, and the strain in her voice made Twilight feel hot with confused arousal and perhaps even a little bit of guilt. The poor bug sounded so pent up, and it was all Twi's fault... and, well, she did really, really want an egg.
Twilight opened her mouth, closed it, then opened it again, and she shuddered a little as she felt her pussy clamp down onto nothingness again. Quivers ran down her spine as Tenti nuzzled her neck, and she quickly huffed a soft "Y-Yes! G-Give me one of your eggs, I-I want to know everything about how it works, a-and first-hoof experience is a good way to gather data on-"
As soon as she heard a yes from the princess, Tenti shuddered as she set to work producing herself an egg, and once that was set into motion, all she had to do was mount the princess. Her throbbing shaft was dragged along Twilight's flanks as Tenti smoothly slid herself on top of the mare, before she stood up overtop of Twilight. Two of her tentacles wrapped around the Princess' hind legs, and she forced the mare to stand up, spreading her hind legs open so she could properly mount her.
Tenti's belly was stating to bulge, and that meant she was already crafting a nice big egg inside of herself. As the queen began to mount her, Twilight could feel Tenti's belly pressing softly against her back, smooshing against her a little thanks to the egg she was crafting. "S-She's already starting to bulge with the egg...!?"
Two more tentacles coiled around the Alicorn's front legs as Tenti slid atop her, and the cock-tipped tentacle coiled gently around her neck. The drooling vine hung near her snout, but it didn't try to make it inside, not yet. And most importantly, the purple mare would soon feel the slightly-flared, drooling tip of the queen's thick shaft smoosh against her folds, splurting a gush of slippery precum, half of which made it inside of her. As the fluid squirted into her marehood, flooding her tunnel, the princess faintly gasped as she felt a rush of magical warmth sinking into her, sending tingles from the tip of her snout all the way down to the tips of her teats. And then on down to her hooves, too.
Tenti shivered a little, then she began to push, her cock squishing against the mare more firmly, grinding against her lips, until... it popped inside, letting Tenti happily coo with pleasure as the flare was buried inside of tightly squeezing mareflesh. She smoothly rocked her hips forwards, and the queen's twitching shaft slowly sank into the mare. Tenti didn't make Twi wait, either. She just kept pushing, stuffing her medial ring inside, working her cock all the way inside until she felt her flare smoosh against the entrance to the mare's womb.
Twilight was left struggling in desperation to handle the sensations coursing through her, as the Queen's shaft sank deep into her folds. The cock was huge, but it was also... squishy? It stretched her open in a different way than a huge cock normally would, and something about the way it filled her to the brim felt three times as pleasurable than any of the toys the purple mare owned.
Tenti gave the princess one more gentle thrust, and she shuddered with a blissful groan as her flare squished into the mare's womb, her cervix loosened by Tenti's special precum. As it slipped inside, her womb was flooded with a thick gush of precum, just as Tenti's sheath kissed the mare's lower lips.
Now that it was all in, Tenti's heavy nuts were pressed against Twilight's ass, heavy and swelling with the queen's slippery precum. Or was it simply cum? The mare's nuts only produced her thick, sweet, love-laced lubricant, and lots of it. The eggs, of course, came from deeper within her body, and she could route them either through her cock, or through her cock-tipped tentacle, if she wished.
Now that Tenti was hilted, she began to adjust her tentacles. The tentacles coiled around Twilight's hind legs adjusted, tightening their grip, but they also snaked themselves upwards, making Twilight squeak as she felt them wind around both of her teats. They gave her boobs a firm squeeze, then they both pressed against her nipples, before slowly opening up and enveloping each of the heavy mounds. The princess helplessly squirmed as her teats were sucked into the tentacles, where Tenti could massage and suck on them, both things that she started doing almost right away.
To the mare's surprise, she quickly felt milk begin to pour out of her teats, turning the two tentacles white as the fluids were routed into Tenti's body. Tenti gave the mare an affectionate lick on the neck as she snuggled close to her and wriggled her hips, making her cock shift and twitch inside. The tip of her cock consisted of petals that briefly opened inside of the Alicorn's womb, briefly brushing against her inner walls, a small hint of what it would feel like when they later locked themselves inside of her to make way for a big, heavy, squishy egg.
Now that she could feel every inch of it, Twilight was certain that Tenti's cock was far different than that of a normal stallion. it was thicker, longer, but also squishier. If the mare clenched, she could briefly compress Tenti's cock down to the size of a normal stallionhood, but then it would simply stretch her open again~. Whenever it twitched, either on its own or from Tenti flexing it, it would harden somewhat, shifting and grinding against Twi's slick inner walls.
Now that she was being milked, Twilight began to squirm and whimper, panting heavily as she gently rocked her hips back against Tenti. She barely even realized what she was doing, her mind struggling to comprehend more than wishing that the cock inside of her was moving.
Thankfully, she didn't have to wait long. Tenti adjusted her stance as she ground her cock down into the princess, then she planted her hooves on the bed, nuzzled her snout close to Twi's neck, and pulled. With a lewd, wet schlick, Tenti's cock escaped from Twilight's gripping depths, sliding out of the Alicorn as she whined in desperation and clamped down tightly around it.
Right as the medial ring escaped, however, Tenti began to slow down, before she switched her momentum around and began to thrust back inside. Without hesitation, she sank the full length of her cock back inside of Twilight, letting her flare squeeze into Twilight's womb again to bathe it with another warm gush of her seed.
Before Twilight even had time to beg for more, Tenti pulled back for another thrust. Her rhythm started off shaky, but soon enough she began to give the princess a proper rutting, using her tentacles for extra grip and stability as she rocked against the purple mare beneath her.
Twilight was struggling to handle the intensity of the rutting she was getting; not because it was rough, but because it was loving. Tenti wasn't just plowing her into the bed mindlessly, she was making every thrust count, pumping into her firmly enough to shake the goo bed, but not enough that it was overwhemling.
She stayed close to Twilight, moaning in sync with her, enjoying every last soft plap as their hips smooshed together again and again, complete with the softer, more gentle plaps of Tenti's heavy balls coming to land on Twilight's soft ass at the end of each deep thrust.
Every single time Twilight recalled that the end goal of this fantastic rutting was to have her womb filled with an egg, she would clench tightly around the cock inside of her, and her orgasm would jump closer. She struggled to hold back, but the more she tried not to think about being bred, being a broodmare, her belly swelling with another mare's young, all because of the thick marecock pumping into her...-!
Twilight let out a loud, shaky, "AaahhhhnnnnnIIIIILOVEYOUTENTIIII~!" as the thoughts built up too far, sending the purple alicorn into a messy, noisy orgasm as she began to twitch and squirm beneath the queen.
Tenti felt her cheeks turning a hot red from Twilight's cry of ecstasy, and she found her own mouth opening as well, her own orgasm rushing to join Twilight as she let out a softer, but still loud "I-I love you too...~!" She shuddered amidst her thrusts into the slightly smaller mare, her cock gushing more and more of her slippery fluids inside.
Until... she couldn't take it anymore. Tenti began to thrust harder into the orgasming mare, but Twilight's marehood was repeatedly and tightly clamping down onto her cock, trying to keep her inside so it could milk her, and aid in her quest to breed the purple pony princess. Her harder, audibly-plapping thrusts only lasted a little while before she collapsed against Twilight, rammed her cock as far as it could reach inside the mare's strongly orgasming pussy, and tightened her tendrils around the princess to pull her close.
That wasn't all- as Tenti's petals opened inside of the mare's womb, they sealed it shut, both magically and physically, locking the two mares together. As Tenti's orgasm overwhelmed her, the mare's almost-forgotten cocktacle suddenly plunged its way down Twi's throat, filling her with cock at both ends.
Because, as the Princess would soon find out, when Tenti came, she came from both ends. Her thicker, larger cock lodged inside of the mare's squeezing pussy erupted with fat gushes of slippery cum, and the cock-tipped tentacle began to pump some more of the fluids down the mare's throat as well.
But then there was the egg. The bulge in Tenti's belly began to shift inside of her, making the queen squirm and twitch as she felt the egg begin to squeeze down into her cock...
Quite unexpectedly, the flow of cum was cut off from the bug's shaft, as Tenti's cock began to swell inside of her... Twilight's orgasm began to taper off, which left her hyper-aware of what began to happen as Tenti's egg began to emerge. She felt the Queen's shaft begin to bulge, starting at her outer lips and sinking into her body. It was the egg, squeezing its way inside of her!
The egg was huge, but very squishy, which meant that while it was being laid, it would spend a while being inside the wombs of both ponies at once. As the egg began to emerge into Twilight's womb, it was still mostly held within Tenti's egg chamber, though her cock and her body was slowly, and pleasurably, pumping it through into Twilight.
It seemed that even though her cock wasn't pumping cum into her anymore, Tenti was still cumming. The cock buried in Twilight's throat was still gushing small amounts of cum, and Twilight slowly pulled on it with her hooves until she managed to get it out of her throat, but still within her mouth. It allowed her to get a taste of the mare's cum, and it let her swallow it herself which felt extra arousing and... and hot.
As Tenti's egg slowly squeezed into the princess, the queen weakly humped against her, which made her cock shift and grind against the mare's stretched, slick inner walls, but at no point did it ever pull out, even a little, as the petals of Tenti's cock had glued themselves to the inside of her womb. Even though Tenti had stopped filling her with cum, the tentacles holding onto Twilight's teats continued to massage them, sucking firmly on each one to continually drain milk from the mare. Perhaps to replenish something, but what?
With Tenti humping against her, gradually filling her with an egg, Twilight struggled to focus on the sensations instead of focusing on the plrasurable sensations. Even worse, she could feel another orgasm approaching! It was all so arousing, so pleasurable, that she began to worry she was going to be cumming all over again before she got to feel the egg pop inside all the way. Unknown to her, the egg finally squeezed its way out of Tenti's womb... but as it began to slide down her cock, the queen's shaft continued to maintain its thickened, bulging state. Even as the egg was sliding down the tip of her cock, filling the mare's womb, Tenti's cock stayed thickened inside of her.
The princess would find out why as Tenti grew quiet, her entire body tensing, right as the egg finally sloshed its way into her womb. The feeling was indescribable, for both parties. The egg didn't just slip inside- it was pushed inside, by a torrent of thick, slippery cum that was backed up behind the huge, softened plantling egg.
As the egg was fired into her womb, Tenti loudly cried out with orgasmic ecstasy as all of the backed-up cum audibly splurted inside, making her belly bloat out even further as the queen's orgasm was revitalized. Twilight squirmed as the egg finally finished its journey, and as Tenti flooded her already-stuffed womb with more fresh cum, the princess had no choice but to give in to her orgasm as well.
Tenti made cute little gasps and squeaks of pleasure as she humped against the princess, unable to stop herself from grinding into Twilight's pussy as it began to squeeze and milk her cock. Twilight was hungrily sucking on the cocktacle by this point, and she moaned as it plunged even deeper down the her throat , just in time for little bulges of her cum to begin traveling down its length and then down her throat.
Tenti was held there, twitching and moaning with pleasure, as both of her cocks pumped the broodmare full of her cum. It was out of her hooves by this point... her body and her instincts were in control, and they were breeding the needy broodmare that was ensnared within her tendrils, trading her milk for gush after gush of thick, slippery plantling cum. It wasn't until Twilight's belly was swelled even further with the queen's fluids that the bug's orgasm finally began to fade, leaving her panting softly and shivering against the princess.
Tenti was clearly different when it came to changeling breeding... the princess was left with just one egg, but it was huge, squishy, and very fertile. All of the cum pumped into her womb had given the egg an insulating layer of fluid to keep it safe and warm, and all of the cum pumped down the mare's throat was laced with love and nutrients, filtered from the cave's natural mineral water, to keep both the egg and the new broodmare healthy and fed for a while.
Tenti, of course... the queen had expended a lot of water breeding the egg into her friend, and as she sagged against her on the bed, she unwound one of her tendrils, slithering it off of her bed and over to one of the little streams of water running through her bedchambers. As she began to pipe fresh water into herself, drinking through the tendril, she slowly pulled the cocktacle free from the mare's maw, while covering her neck in kisses.
She let the mare take in a deep breath, but then Tenti pulled her into a brief, but warm kiss, right on the lips. Only then, after breaking the kiss, would she softly whisper "T-That was amazing... I-I haven't laid one this big in so long..."
Twilight didn't even know what to say. All she could manage was a weak, shy little "T-Thank you, s-so much..." as she felt her body slowly starting to untense. She was thankful that Tenti slowly rolled over onto her side, bringing Twilight with her. The movement made her cock shift and grind against Twilight's insides, but she managed not to moan as she snuggled back against Tenti again.
The Queen slid a hoof over Twilight's belly, and she slowly rubbed the purple mare's swollen belly, sending a faint shiver through both mares. Her cock gently throbbed, and she quietly said "T-This little drone might not even need a week before they're ready..."
"R-Really...?" Twilight weakly said, unable to resist entertaining her desire to learn more, even as she began to drift into a warm, snuggly afterglow.
"Mmhmmm... the drone will hatch inside of you, absorbing what's left of the egg... it will crawl out on its own when it's ready, so it's more akin to giving birth, but... easier, than it is for you ponies..." Tenti quietly hummed, though her tone was unmistakably... motherly as she spoke to Twilight, slowly rubbing circles into her cum-filled belly.
"Amazing..." Twilight whispered, as her eyes drifted halfway closed. Still, her horn flickered to lift as she brought her notepad close, starting to write in it once more as Tenti curiously watched over her shoulder.
To the queen's surprise, Twilight's writing slowed down until the pencil was suddenly dropped, startling her just slightly. She soon found out why, as the purple mare she held close let out a quiet, but somehow happy sounding snore. Tenti giggled a little bit, then she gave Twilight's neck another kiss, whispering a soft "love you, Twi...~" as she snuggled herself close and closed her own eyes.
✩｡:*•.──────────.•*:｡✩
"Hey, how come I don't smell that heat anymore?" Polaris asked, gracefully bowing as he held open the door for Twilight to enter the garage. The alicorn wore a hot blush and a scrunch, and yet... there was a faint smile hidden beneath it all, too.
"Oh, just..." she softly said, "Studying doesn't always have to be boring..."
The blue stallion chuckled a little, saying, "Yeah... but... also, I wanna say thank you... I uh, it's kinda hard actually, to find ponies that Tenti trusts... like, really trusts, because there's a difference between me trying to introduce her to someone that I trust personally, and someone that she puts her own trust in, you know?"
Twilight knowingly nodded along, her scrunch mostly gone as she smiled in return, though she looked a little bashful as she said "Well, I'm... I'm glad to help, she's really cool to be around, and I love learning about her, and all of her drones..."
Twilight watched as another changeling trotted up to Polaris' side, his mane tied up in a ponytail this time. This bug wasn't as unique as Tenti, but he was still interesting, as he refused to visit Thorax's hive and undergo a reformation. She didn't blame him; he lived with Polaris, a damn near infinite source of lust (and love), so much so that he had been able to patch the holes in his natural form and give himself a proper, silky mane.
And frustratingly, he could be just as teasing as Polaris always was. "So, after this one hatches, you gonna take another one of Tenti's eggs~?"
With all of the thought she'd put into studies and thinking about the current egg, Twilight hadn't even thought about it. And yet, as her snout burned a hot red, she- and the two stallions in front of her- already knew what the answer was.
