For "Science", of Course!
Sunny Starscout carefully climbed over a rotten tree as she made her way deeper into the depths of Bridlewood Forest, wincing as a stray branch snagged in her mane. Swatting it away, she took a breath to calm herself, glancing around at the twisted trees. "Calm down Sunny, Alphabittle said he saw Izzy head this way plenty of times, so this part of the forest can't be that dangerous... right?" She mused to herself as she climbed over a fallen log.
It seemed like ages before she found anything, a path veering off to the thicker part of the forest... which eventually led her to a massive, twisting cavern of tree roots. Taking a moment to collect herself, Sunny carefully entered the cave, navigating, treading lightly as she looked around for anything that might be stalking her. "What is Izzy even doing in a place like this?" She whispered to herself as she nervously walked through the cavern, unsure of where she was.
She was brought out of her thoughts, however, when she heard the sound of somepony… singing?
Arching a brow, Sunny made her way towards the sound, the tunnel eventually leading into a sort of cavern, several vines were hanging from the ceiling, and a stream of water flowing from a small cave near the top and flowing into a lake at the very center that was roughly the size of a large pool. As Sunny carefully entered, the singing got louder and louder, her curiosity overcoming her fear as she took in the scenery.
Sunny took a step forward, about to call out to her… only for the Unicorn to stop singing as she stood up… and casually started removing her clothes.
Sunny felt her cheeks heat up as she watched Izzy strip off her top and her skirt, she let out a quiet gasp as she watched her friend flaunt her rather voluptuous body, leaving her in nothing but her silken bra & panties, and it wasn't long before she removed those as well.
The trail of clothes she left behind made Sunny shiver as she watched her friend jump into the lake naked, happily kicking her feet and splashing water everywhere. 'Huh... so she just came here for a swim?' Sunny thought with an amused smile, watching in silence as her friend swam about in the lake. 'And here I thought it was something weird-'
Suddenly, the sound of rumbling echoed throughout the cavern, snapping the Earth Pony out of her thoughts. Bubbles started rising to the surface of the lake, Sunny found herself hiding behind a large root as she watched from afar, the water continuously bubbling as several creatures rose from the depths of the lake. First was a single lime green vine with a closed bulb on the tip, then four larger vines rose around the swimming Unicorn, who seemed completely oblivious to the danger she was in.
Feeling uneasy, Sunny took a step forward, ready to utilize her magic to save her friend from this strange creature...
"Hey, sweetie!" Izzy playfully called out as she stopped swimming, giggling as the vine with a bulb slithered towards her. "Didja miss me?"
Sunny blinked in surprise, did Izzy just...?
The vine affectionately wrapped around Izzy's left hand and started sucking on her finger, the Unicorn letting out an adorable giggle as she kissed the bulb on the tip. “Aww, I missed you too! C’mere..” She cooed as the bulb opened, revealing several smaller vines inside, each one slipping into the Unicorn’s mouth as she opened wide, welcoming the creature’s embrace as it latched onto her mouth, while offering no resistance as the four remaining vines quickly wrapped around her limbs and lifting her out of the water.
The Earth Pony was barely able to process what she was seeing. What were these creatures? Why were they so familiar with Izzy, to the point where they were willing to touch her without a second thought? How was Izzy so… comfortable in her predicament to the point where was basically inviting the vines to embrace and molest her?!
However, her more curious side started to surface as she continued watching the two "making out". Throughout all of her time researching the various species of Equestria, no book she'd read had ever covered a creature such as this! In fact, the only creatures remotely close to the one Izzy was interacting with… were the fabled Plunder Vines from Ancient Equestria!
'Could this be some sort of subspecies? A distant descendant perhaps?' Sunny mused to herself, watching as some of the vines gently caressed the Unicorn's legs… only for Izzy's magic aura to surround them, pulling them up to her thighs.
Part of her was tempted to call out to her friend, to put a stop to this before things got a little too raunchy… however, this was a species that had never been seen before, and it appeared to be on friendly terms with her friend. 'It doesn't appear to be forcing itself on her. If anything Izzy seems to have complete control of the situation… which makes this a golden opportunity to study the creature from afar!'
Her curious yet nervous expression was quickly replaced by one of intrigue and excitement as she quickly reached into her satchel and pulled out a notebook and pen. The Earth Pony carefully crept closer, taking care not to make any noise as she knelt behind one of the bigger roots and started writing, secretly hoping that Izzy would coax the creature into giving her as pleasurable an experience as possible…
Purely for scientific purposes, of course!
The two vines keeping her arms bound carefully slithered up to her shoulders and under her breast, the Unicorn letting out a pleasure-filled groan as they playfully teased her nipples.
"Mmmwaa~" The Unicorn gasped as the bulbed vine ended the "kiss", giving her a playful boop on the nose as a second bulbed vine rose from beneath the surface of the lake. "Oooohhh, hungry are we?" She giggled as she shook her breasts teasingly, almost begging the two to suckle on her nipples… and shivering with glee as both bulbed vines complied with her wishes, eagerly latching onto her nipples while the ones that had teased them prior settled for gently massaging her breasts.
"EEE-Hehehe~!! Oohhh yeah-GLULK!" Izzy started to giggle, but was cut off as a thinner vine emerged from the water, and took the opportunity to push itself into the Unicorn's mouth. "Hmm? Mmm~" Surprised, yet not remotely bothered by the new vine invading her mouth, she happily suckled and slurped on it, allowing the vine to gently slide through her closed lips, slither over her tongue and burrow to the back of her mouth before diving down past her esophagus and down her throat.
The moment Sunny witnessed this she almost dropped her pen in astonishment, judging by the size of the visible bulge in her neck, that vine had dived nearly ten inches down Izzy's throat on that first push!
And if the Unicorn's muffled giggles were anything to go by, she was enjoying every second of it!
'Does this mare even have a gag reflex!?' Were Sunny's first thoughts as a few more vines rose out of the lake. Shaking her head, she quickly decided that was a question for later and continued taking notes.
Meanwhile, Izzy breathed slowly through her mouth, gently stroking the vine with her tongue while sucking and slurping on it. The vine then started moving back and forth in and out of her mouth in response, allowing her to bob her head up and down the vine, humming gently as she continued to suck off the creature, taking its vine deeper into her gullet with each bob.
However, after a few minutes, Izzy's eyes widened as she glanced down at the vine practically lodged in her throat, which had started twitching. Opening her mouth a little she very gently bit down on it, seemingly giving a signal to stop. Not wasting a second the vine complied, pulling itself free from Izzy's mouth… with some purple fluids speaking from its tip.
"Y'know, you don't really need to use so much of this stuff sweetie." She cooed, giving the tip another kiss and licking some of the excess fluids off of her lips. "I'm already horny enough~" She added, giggling as the vines continued stroking and caressing her body.
'I see, so the creature usually injects a potent aphrodisiac into their receptive mate…' Sunny mused as she wrote down more details. '...this appears to be only for the sake of preparing their mate for copulation, but does not appear to be a mandatory process. As shown with subject Izzy's willingness to engage in intercourse.'
As the Earth Pony continued to write, however, an oddly potent aroma caught her attention, prompting her to sniff the air for a moment. The scent reminded her of a garden… yet at the same time had an enticing allure, as if a door had been opened within her very mind…
'Is this… some sort of… airborne version of the aphrodisiac…?' She thought as she turned her attention back to her friend… and saw several bulb-tipped vines dangling from the ceiling, with some of the same fluids slowly dripping out of their tips. 'So that's where it's coming from, must be some sort of instinct or reflex once the creature becomes… becomes…' Sunny shook her head, attempting to clear her thoughts. However with every breath the Earth Pony took her mind became more addled, her heart started beating faster, and her nether regions suddenly became uncomfortably warm.
In the intensely aroma-filled cavern, Sunny's body started to feel more sluggish as her mind was enthralled by the aroma, her muscles relaxed as her arms fell to her sides, with her notepad and pen slipping from her grasp as her head swam… and her left hand unconsciously slid between her legs and underneath her skirt and panties.
The Earth Pony eagerly started fingering herself while using her right hand to squeeze her breast through her shirt, her body quivering as she found herself unable to look away, her gaze transfixed on Izzy as she let the vines ravage her body without a care in the world. 'This is… this is for research…' She mentally told herself as she slowly inserted her middle and index fingers into her marehood, biting her lip as she used her free fingers to tease her quivering outer lips…
"Now now, Sunny…" A familiar voice chimed in. Sunny blinked in confusion as she turned her attention away from the creature ravishing her friend… and saw a familiar Earth Pony Stallion spreading her legs. "Let me take care of that for you~"
"H-Hitch…?"
"Alright big boy, enough teasing. I'm ready for some real action~" Izzy smiled, giving the creature a seductive wink, her toes wiggling with anticipation as she felt the two slimy vines holding her legs slithering up to her nether regions while spreading them as wide as they could, forcing Izzy into the spread eagle position.
Both vines then lined up with her pussy and anus… and plunged into the Unicorn without a moment's hesitation.
"Oh-HOOOO F-F-FUUUUCK!!" Izzy screamed as she arched her back, pleasure coursing thru her as the vines pushed themselves further in before they started to pump in and out of her holes, lubricated with both Izzy and their own fluids. "D-don't… don't stop…" The Unicorn gasped as she felt the utter pleasure coursing through her, struggling as much as she could while the vines shoved themselves further inside her holes with each thrust. "Yes! That's it!! Shove them in me, please! Fuck me! Fuck me, fuck me, FUCK ME!!!" She cried out as her vaginal secretions dripped down the vines, aiding their fluids with lubricating her holes as they continued to violently thrust in and out of her.
Izzy's eyes rolled upwards as she started instinctively bucking her hips. "M-more! Oh sweet Faust, m-more!" She begged as the vines continued to piston in and out of her ass and pussy in an alternating fashion, pulling back and slamming back into her, again and again, and again as they continued to fuck her as roughly as possible. "M-M-MORE! F-FUCK ME MOOOORE!" The Unicorn panted and gasped, writhing in pleasure as the vine in her marehood continued pumping in and out of her, her hips, in turn, thrashed and pushed back against the vine probing her anus, causing her pleasure to flare up and making her drool with excitement at the feeling of both vines invading her body.
After a few more minutes, both vines slowly and agonizingly withdrew themselves from the Unicorn's marehood and anus. Izzy shuddered as she felt her inner walls tugging at them both, her body desperately trying to keep them inside of her, each pull earning a blissful moan from the Unicorn as she squirmed in their grasp. "Y-Y-Yeeees… pluh… pluheese… d-d-dooo it~"
The creature complied, waiting until it was one tug away from exciting both of Izzy's holes… before slamming both vines into her, pushing even deeper than before. Izzy saw stars as a nearly unbearable surge of sexual pleasure shot through her entire body, opening her mouth as wide as possible in an attempt to scream again. "AGAAAHHH-GLURKK!?"
However right as she did, another vine thrust itself down her throat in one swift movement, cutting her off.
Behind the massive root, Sunny shuddered as Hitch hovered over her marehood, her eyes drawn to his impeccable abs, as well as that massive throbbing monster between his legs. "Oh Sunny… you're so beautiful…" The Stallion smiled, bending down and giving her pussy a gentle lick, sending waves of pleasure throughout her body.
"Yeh… yeeeesh…" The Mare tried to reply, but ended up slurring her words, her thoughts clouded by lust as she gave in to her desires and Hitch's advances, any semblance of rational thought she might have had vanished as she felt Hitch's stallionhood pressing against her entrance. And it wasn't long before he slid his shaft into her completely, filling an emptiness that Sunny didn't even know she'd needed to be filled. "Ah! Ahhhhh… heheh… ee-he-he-he…"
In reality, however, the mare was lying against the root staring up at the ceiling with a relatively goofy and dazed look on her face, her eyes glazed over as she slid her fingers across the sensitive surface of her clitoris, her body shuddering at the feeling.
Sunny had seemingly ended up stuck in a sort of entranced daydream, completely unaware that the handsome stallion before her was merely a figment brought about by the fumes from flowers above her combined with her own unsated arousal.
"Mmm… Ohhhh Hitch… that's it, right there~" The captivated mare sighed as she toyed with her nether regions, sending waves of pleasure through her body, her legs quivering as she arched her hips against her own moving fingers, Her fantasy deluding her into believing her friend was repeatedly pumping his shaft into her, over and over again. "Harder… oohh yes! H-Harder! Yes… ooohhh YES~!"
Back above the lake, Izzy was in heaven as the vines continued to fuck her nice and hard. The Unicorn writhed in pleasure and moaned in pure bliss, her eyes rolling to the back of her head as the vines pumped in and out, lubricated by their unified fluids and fucking all of her holes in unison. "Mmmphh, mmmhmhmm~" The Unicorn groaned around the vine, shuddering and squirming as she was practically impaled by them with each thrust. Her whole body felt amazing, with the way the vines rubbed against her stretched walls filling her with a sense of utter bliss.
"Mmmmhmhmpphhh!" She giggled as the three vines squirmed deeper into her sensitive body, her hips twitching and jerking as she bucked and ground against the thick vines. The bulbed vines latched to her breasts eagerly tugged at her nipples, causing her to squeal as her body tensed and squirmed, the vine pumping in and out of her pussy shifting into a new rhythm, ensuring her orgasm was imminent. Izzy's vision began to swim as wave after wave of pleasure spread throughout her body, the vibrations of the vines intensifying as they ravaged her holes, the Unicorn's breaths becoming more ragged and labored as the vines pounded deeper into her body.
Her body was stretched to the maximum, her chest heaved up and down as she breathed loudly, her eyes beginning to roll back as she slowly and deliciously collapsed against the vines, giggling as she shifted her hands to run her fingers across the grapevines intertwined in her arms. Even the smallest touch was enough to send shivers down her spine, sending more sensations of pleasure through her body. "Mph! Mph! MMMMPHH!!" Izzy moaned as she began to shake uncontrollably, throwing her head back as the vines fucked her harder and harder.
And then suddenly, the vines stopped moving.
At first, Izzy was confused, only for the vines to start twitching as small bulges traveled through each vine towards her vulnerable body. The Unicorn knew what they were and what was happening.. and eagerly awaited it. Izzy's juices were already flowing, her body tensing in anticipation as she felt the first load traveling up the vine and into her ass. "Mmmhm.. oooohhh gggoooowwwwwnnnn… Ohhhhmhh!" Izzy shuddered with excitement and lust at the sudden intrusion, her cheeks flushed while eyes rolled back in her head, her thighs squeezing tightly around the vines in an effort to prolong the pleasure. The vine in her ass was the first to fully climax, its seed erupting into the deepest recesses of the Unicorn's ass, their juices spurting out around the vine and coating Izzy's twitching anus in its fluids.
The vines in Izzy's vagina didn't last nearly as long as the Unicorn felt another bulge pushing its way into her marehood. She grunted loudly around the vine as her body jerked wildly, it felt so good to have her marehood being stretched! The Unicorn felt her mind quickly becoming overwhelmed by the sensations as her vaginal walls contracted around the vine. "Oohhhhhhhmmmmmhh!" Izzy groaned as waves of pleasure crashed throughout her body, the walls of her pussy tightening around the vine, almost as if her marehood was milking it for all its worth, her legs trembling as she finally came, her entire body vibrating with pleasure as the fluids of the vine erupted within the depths of her pussy, her body succumbing to the intense pleasure they were putting her through.
At the sudden release of the vine's seed within her pussy and ass, Izzy convulsed around them, her mouth getting stretched wide as the final bulge was forced into her mouth and down her throat. "Mmmoooong!" Izzy breathed heavily as she slowly opened her eyes, staring at the massive vine as she happily swallowed it down, and looked down to see her belly starting to bulge outwards.
…and she loved it!
Eventually, the vines in her pussy and mouth finally stopped cumming and withdrew, the one in her stuffed ass was pulled out next, plopping out of her and back into the lake.
The Unicorn happily hummed in delight, the taste of the vine still lingering in her mouth as she was gently lowered near the edge, leaving trails of saliva that lingered on her body. She felt the vines down her stomach harden, pushing the large bulges further into her. "Ohhh.." She sighed as the vines positioned themselves in a less obvious way, roughly pushing them into her. "Mmphh.." She panted as the vines began slowly pushing into her. She continued to groan as the vines began pressing further and further into her, her marehood squeezing harder and harder. "Mmmmmmmmmm" The Unicorn happily hummed in delight, the taste of the vine still lingering in her mouth as she was gently lowered near the edge of the lake, trails of their seed leaking from her marehood and anus as she staggered towards one of the roots. "Mmphh... he-he-heee… oooh that was nice~"
"Mmmm… ooohhh~"
Coming down from her orgasmic high, Izzy blinked as she looked around the cave. She could've sworn she'd just heard moaning…
Within her lust-fueled daydream, Sunny's tongue was hanging out the side of her mouth as "Hitch" slammed his shaft into her over and over again.
"Yes… oohhh Hitch… I-I need this…" The mare cooed as she wrapped her legs around Hitch's hips, her vaginal walls squeezing his stallionhood every time he buried it in her marehood. She could feel it pulsing, twitching, and expanding with each thrust…
In reality, however, the Earth Pony furiously plunged her fingers into her winking slit, thrusting them in and out as she arched her back. Shallow breaths escaped her lips as she kept moaning in rapt anticipation, the very thought of "Hitch" cumming inside her made her body warm all over, her hips pushing against "his" thrusts.
"H-H-Harder Hitch! F-F-Faster!!" Sunny gasped, her fingers were soaked with her pleasure fluids as she started furiously rubbing her clit with her thumb as she felt her own climax fast approaching, inching closer and closer to the peak of pleasure.
Then, as shriek echoed throughout the cave as she experienced her own climax, the blissful sensations shot through her body as she bucked her hips, pulling "Hitch" closer and forcing him to bury his cock as deep inside her as possible. "OH YES! OOOHHH F-F-FUUUUCK YEEEEES!" Sunny screamed, leaning back against the root and squirting her juices all over her fingers as well as the ground as she "felt" the stallion's seed erupt inside her, the explosion of ecstasy strong enough to make her hips spasm and her legs quiver as she gasping in ecstasy.
"Sunny…"
Then finally, with her fingers stained with her juices, Sunny shuddered as the blissful afterglow took over her senses, her thoughts filled with nothing but pleasure.
"Sunny?"
"Hey Sunny. Sunny?" Izzy called out, snapping her finger in front of the Earth Pony's face. "Waky-waky~"
"Uhh… h-huh…?" Sunny yawned as she slowly came to, her blurry vision clearing as she stared at her friend. "Oh, hi Izzy... IZZY!?" The Earth Pony yelped, snapping out of her orgasmic high as she staggered to her feet, her face red with embarrassment. "W-Who? What, where-"
"Didja enjoy the show?" The Unicorn giggled, her sex still oozing with sticky juice, her shorts stained with her juices as well.
"I uh… n-n-no, I didn't…" The Earth Pony finally managed to answer, her voice sounding weak and broken.
"Ooh really? It sounded like you wanted nothing more than to ride your stallion ~" Izzy giggled, shaking her head in amusement. "I gotta say, I'm surprised you and Hitch haven't gotten it on yet-"
"IZZY!!" Sunny snapped in exasperation, cutting her friend off before pointing at the remaining tentacles hovering behind the Unicorn. "What. Is. That?"
"Oh, just a friend I made sometime after we got our magic back." She casually explained as the creature handed her her discarded clothes. "He was really pent up, and I hadn't gotten any in a while... one thing lead to another and..." Izzy planted a kiss on one of the tentacles, her voice dropping into a seductive whisper. "...we came to an understanding...."
Sunny shuddered in response... and then remembered that vision of Hitch she'd witnessed. "Wait, why did I see-"
"Your not-boyfriend?" Izzy interrupted with a smirk. "Yeah, that might have something to do with the fumes you inhaled. My friend tends to let a lot of that stuff out when he gets really horny." She explained, levitating Sunny's notebook and looking through the pages. "Personally though, if you wanna study him that badly, I'd suggest a more hands-on experience..."
The Earth Pony took a step back, her cheeks heating up again. "You... you're not-I mean, I don't-" She stammered nervously, while the Unicorn before simply giggled in response.
"It's OK Sunny, there's no need to be afraid, everything you saw back there was 100% consensual." She explained, tossing the notebook over to her friend and grabbing her clothes. "He'll never do anything you don't want him to~"
While Sunny tried her best to think up a coherent response, the Unicorn playfully skipped past her towards the exit. "Oh, and you might wanna think up a safeword~" She giggled before disappearing into the forest.
Now alone with the creature, Sunny looked in the direction of the cave's exit… then back to the creature, its remaining tentacles were just hovering there, seemingly waiting for her response. The Earth Pony picked up her belongings and carefully made her way towards the exit, occasionally peeking over her shoulder just to make sure the creature wasn't following her… however, to her surprise it wasn't. In fact, it seemed to be retreating into the lake…
Then, just as she reached the exit, Sunny stopped, looked over her shoulder one last time, took a deep breath… and turned around.
The Earth Pony unbuttoned her shirt, kicked off her shoes and socks, and strutted towards the lake in nothing but her bra and panties, tossing her belongings to the side as several of the creature's vines slid out of the water and slithered towards her body. Sunny bit her lip, shuddering as two of them slid up her legs, another two wrapped themselves around her arms as the other two slid up to her waist, and one more wrapped around her waist.
With her firmly in its grip, the vine around her waist slid between her breasts and up to her face, revealing itself to be one of the bulbed ones that suckled Izzy's nipples, now hovering directly in front of Sunny mouth. It carefully opened up and pressed itself against her lips, her mouth opening and welcoming all the smaller tentacles inside.
As the vines began to pull her towards the lake, many more Vines erupted from the depths. Sunny simply closed her eyes and relaxed, ready to experience all the creature had to offer…
For purely scientific purposes, of course…
