Twilight whistled happily as she skipped down the stairs of the Royal Research Academy's Botany Division. Normally, only the ponies involved in ongoing research were allowed into the laboratory and containment section of the academy, even being the Princess’s student hadn’t gotten the young mare access. Today was different; Twilight had been granted official researcher status as part of a gift from the princess for her fourteenth birthday. She had already passed all of the requisite classes at that point any ways as well as the sixteen hours of safety briefing and now had access to the entirety of the vast academy as well as its tools and resources...as long as she used them responsibly.

With all of that responsibility in mind, Twilight was on her way to find something small to start her research with. Something to get her hooves wet as well as get used to the facilities. Botany didn’t normally hold that much interest for her, at least compared to things like astronomy and arcana, but when she stepped into the Flora Librarium her breath was stolen away.

Rows upon rows of hard wood shelves stretched across the massive room, each holding dozens of different plant species stored in magical stasis. Behind the shelves was a large open space filled with patches of different soil with several different plant specimen growing in them. The whole room was lit by the open glass ceiling and each soil patch had a plate of magical glass suspended above it, that could independently change the amount of light the patch got.

Twilight couldn’t help but hop from hoof to hoof as her eyes travelled from each row to the next. She started trotting along the outside of the shelves and peering down the aisles. With no clear destination in mind she was careful to mentally catalog each plant stored in the aisles. When she reached that last row however, all of the dormant plants were placed in cages. This was probably the most exciting part of the whole room and Twilight hummed happily as she started down the aisle.

All of the plants kept in this isle showed varying signs of mental awareness and had to be secured so that if the magical stasis wore off they didn’t try and run away, or in the case of the Logiticus Lotus and Argumentum Arborialis, argue incessantly and very loudly. These plant were the pride of the Flora Librarium and Twilight couldn’t wait to get her hooves on one of them, but which one?

She read each tag extensively in her search. The Logiticus Lotus sounded intriguing but according to the description, though it was able to hold highly intellectual discussions, its attitude was condescending and rude. The Berry Bombidaris also looked neat, the fruit perportedly being very tasty, but she wasn’t sure if she was ready to deal with the bush they grew on trying to literally shove the berries down her throat. Of course nothing in this area was truly dangerous, all of those plants were sealed off in the vault deeper in the Librarium along with the Black Lotus, Red Lotus, Orange Lotus and Green Pear, but Twilight still wanted something a bit more laid back to experiment with.

When she found the Aphromia Tentacus though she paused. The description was very short, reading only “Very Affectionate,” though some pony had taken red marker and added “I hate you Sun Gazer,” much to Twilight chagrin. Ponies should have more respect then to vandalize state property. Regardless, the plant seemed easy enough to deal with.

As Twilight undid the latch and carefully removed the large container housing the plant from the shelf a thick trottingham accent accosted her.

“I wouldn’t take that one is I were you,”

Twilight turned to see a beautiful white flower pointed at her and wrinkled into a frown.

“Oh what would you know?” a slightly foreign voice replied from a slowly shifting miniature tree.

“I know she doosn’t want any of that.” the lotus returned.

“Oh yeah, is that right?”

Twilight didn’t let the Argumentum Arborialis finish as she replaced the stasis spell on the two arguing plants before calmly walking away. Now that she had a subject, she just had to find a lab room and since it was saturday, a day most pony’s had found that they were allergic to working on, it didn’t take long.

The laboratory was a roughly ten foot by ten foot room with a patch of dirt in the middle and a skylight with various gardening tools lined up along the outer walls as well as a water line. Twilight placed the container on a counter off to the side and gingerly removed the top from it. Inside was a large open flower with a closed bud at its center.

Quickly, but smoothly, Twilight removed the flower from the container and began replanting it in the soil at the center of the room. Then with the utmost care, she removed the stasis spell from it. As time returned to the plant, the dull gray color of its petals turned a bright reddish bronze that faded to pink at the edges and the bud at the center became bright white.

Happy with the transplant, Twilight picked the information card up out of the container and began to go over the more detailed fact sheet. She stopped though when a whimpering sound came from the flower. Curious, Twilight carefully made her way over and leaned in to inspect the plant. When her nose got close to the bud, the Flower sprayed a fine pink mist into Twilight’s face, causing her to cough and wheeze as she stumbled away from the plant.

Twilight rushed over to the information card to see what she needed to do to protect herself, but where the card mentioned the mist, all it said was that the discharge was not dangerous in any way. With her fears assuaged, Twilight returned to the plant, not noticing that the room had gotten a little bit warmer. As she continued to inspect the plant, she noticed that the mist had left a sweet aroma in the air and as she took a deep breath of it a slight blush appeared on her face.

She didn’t waste too much time enjoying the fragrance however and began gently prodding the plant in order to elicit a response, she was a little disappointed as the smell of the flower faded though and more than a little excited when the flower, not in her face this time, released another spray of the pink mist. The amount that it sprayed out was far greater than before and the entire room took on it’s aroma.

Twilight was starting to notice her increased body heat, but figured that the room must just have been heating up as the day wore on. What she didn’t notice, was that she was unconsciously raising her tail up a little and partially exposing her marehood. She hummed merrily as she made observations while enjoying the pleasant atmosphere. Something about the fragrance made her excited and energetic and as she continued to work, the blush on her face became a deeper red. When she bent down to get a probe from beneath a counter, she instinctively flipped her tail to the side and pushed her butt into the air, exposing her pussy lips completely. When the slight breeze from the ventilation system blew over her moist marehood, Twilight sucked in a breath. She looked beneath her body and watched with rapt attention as a single drop of arousal fell from her nether lips.

The excitement of science had kept her distracted from it before but as Twilight accessed herself, she quickly wrapped her tail between her legs and backed herself into a corner of the room. She closed her eyes and took several deep breaths to calm herself. Twilight was not very experienced when it came to sex, she had only had her first heat last spring and even then had only pleasured herself reluctantly. She was well read on the biology of it of course, but that didn’t do her any good now.

She tried to clear her head of the encroaching desires but unlike her heat, which had been a battle between the needs of her body and her mental trepidation, she actually wanted to feel sexual stimulation now. Arousal and conscience clashed inside her head until she finally gave into her desires. Like anything else though, Twilight was not going to be caught unprepared. She trotted over to the door of the lab, rubbing her thighs together all the way, and put up the Testing in Progress flag.

None of the laboratories had locks due to safety concerns but it was a rule that unless it was an emergency, ponies were not allowed to interrupt experimentation in progress. With that done, Twilight sat down on the dirt patch in front of the flower and spread her legs apart. She wasn’t absolutely sure why, but being closer to the source of the amazing aroma made her feel better.

Twilight took a moment to look down at her exposed labia. Some young ponies thought that a pony’s private parts looked gross but Twilight had always thought that every part of a pony was a beautiful piece of biological artwork. She gently ran the tip of her hoof along her slit, gasping quietly as the parted slightly, allowing more of her liquid arousal to run free adding the slight smell of her own musk to the aroma in the air. With her other hoof, she gingerly pulled her nether lips apart before pushing the tip of her hoof into her passage. She moaned as the sensitive walls parted and gently pushed her hoof tip in a little deeper before massaging herself in a circular motion. Her movements were inexperienced and jerky but all the same, the sensation and pressure began to build inside her. Twilight pushed her hoof as deeply into her snatch as she could and began to lightly rub her clitoris with her other while letting out little squeals and moans until finally the damn burst.

She shuddered and clenched her eyes shut as waves of pleasure flowed through her before rebounding and concentrating in the spasming walls of her pussy. She arched her back and pushed her hooves desperately against her mound as they were soaked with marecum. Twilight continued to roughly rub herself until the liquid that had built up around her pussy finally caused them to slip off her mound.

When the pleasure finally subsided and she had recovered her breath, Twilight slowly allowed her eyes to open. In front of her face, directly level with her eyes, was a bluish green tentacle. Twilight followed it down and found that the bud of the flower had opened up and several other tentacles had emerged from the flower as well. She looked back up at the tentacle in front of her face and gave it a questioning stare. The tentacle ignored her curiosity though and pointed itself at her mouth, which was still open as Twilight was still breathing hard. Before she could react, the tentacle shot some pink liquid directly into her mouth.

Caught off guard, Twilight was about to spit out the liquid, but before she could, it had mixed with her saliva and become sticky and warm. Unable to rid herself of the goo, Twilight took a moment to calm down and realized that the sticky substance was actually very tasty. She swallowed the goo down and before even thinking about it, opened up her mouth again. The tentacle immediately sprayed more liquid into her mouth and Twilight again happily swallowed it down. When she opened her mouth a third time, the tentacle moved forward and rested itself on Twilight's tongue before spraying more nectar.

Twilight wrapped her lips around the tentacle as gently sucked on it, sighing as she was fed more of the nectar. As this went on, Twilight’s body began to heat up again and before she knew it, her hooves had returned to her pussy and she moaned as she pressed into her walls. She rapidly chased after another orgasm, her pleasure building up faster this time as her lower lips and passage were already pleasantly sensitive from her previous climax. She was soon shuddering as more waves of bliss flowed through her.

She was somewhat disappointed however when the climax ended but that was quickly taken care of as the tentacle poured more nectar into her mouth and with it, Twilight’s arousal burned brightly again. Before she could resume masterbating however, Twilight felt something press against her needy folds. Looking down, she saw another tentacle was brushing up against her soaked nether lips. Normally, she would have hesitated, but with how very horny she was, Twilight pulled her lips apart in invitation.

The tentacle pushed forward easily into her well lubricated pussy and Twilight moaned as it stretched her walls around it. The tentacle continued to push into her until it rested snugly against her cervix, making Twilight sigh in satisfaction at the feeling of fullness. Before she could become too comfortable though, the tentacle pulled out to her entrance, leaving her feeling empty inside, and then pushed back inside much faster than before. Twilight gasped and bucked her hips forward as she was filled again and again, the tentacle falling into a steady rhythm.

Before long, Twilight was pushing into each thrust and gasping every time the tentacle brushed up against her inner barrier. The feeling of the tentacle scraping against her walls, deep inside her, made the pressure of her building climax so much greater and before too long, Twilight was moaning and squirting her essence all over the tentacle and the soil beneath her. The tentacle continued to squirm inside her even as her walls clenched down on it, prolonging her climax making her squirt again and again.

As she came down, the tentacle inside her pussy sprayed nectar into her and as it absorbed into her pussy walls, her arousal returned and grew. Twilight happily sucked on the tentacle in her mouth and patiently luxuriated in her growing horniness. The feeling of liberated sexual desire was thrilling and intoxicating in in of itself but Twilight didn’t complain when the tentacle started moving again. She rolled back onto her back and mewled as the better angle allowed the tentacle pounding into her to speed up and thrust more roughly. Even as her next climax was building, a third tentacle pushed itself up against her puckered anus and forced more of the aphrodisiac nectar into her rectum.

Twilight squirmed as back door became uncomfortably empty and pushed herself against the tentacle rubbing her sphincter. The tentacle took its time though in order to make sure that it didn’t cause Twilight any pain and Twilight let out a long moan as her muscular ring slowly submitted to the new visitor. When the tentacle finally pushed all the way in and sandwiched her sensitive flesh between it and the one in her pussy, she gave a muffled scream and convulsed in bliss as she submitted to another orgasm.

As she began to return from the throes of pleasure, something the the tentacles were doing there very best to delay, Twilight realized that she was not any more satisfied; that her desire for sexual stimulus had not declined at all, even without any more of the nectar. She wondered if the plant was changing her, or at least her libido but it didn’t matter that much to her in the long run. The ever present warmth and horniness, the constant desire that was burning inside her, felt divine. She couldn’t wait to walk around the halls of the castle, tail raised as she displayed her dripping pussy to everypony around her. She wanted the princess to blush when she smelled the scent of arousal coming off her student.

As Twilight fantasized about masterbating even while doing her research in the royal library, the tentacles filled her with more nectar and she shivered as her body became even more needy. The tentacles rapidly pistoned in and out of her alternatively making them scrape against each other deliciously through the thin barrier that separated them and in minutes Twilight was climaxing unfettered again. When she came down this time however, all three of the tentacles retreated from her body.

Twilight groaned in protest but when one of the tentacles poked her flank, she propped herself up and looked at the flower. At its center was a plain looking brown seed.

“Is this for me?”

The tentacle moved up and down in the facsimile of a nod.

Twilight eagerly lifted it out of the flower with her telekinesis. “I’ll take good care of it.”

Twilight was preparing to put the flower back in stasis, but before she could recast the spell, the tentacle poked her flank again. Twilight paused to let the flower do what it wanted to. The tentacle quickly shot deep into her pussy, all the way to her cervix, and shot a big warm ball of nectar deep inside her womb.

She sighed in appreciation as the the liquid added to her constant lust. Twilight finished casting her stasis spell and then returned the flower to its container. Her pussy pulsed distractedly but it didn’t take long for the intelligent young mare to find a solution. She would have to hide the seed anyways. Celestia forbid somepony think she was stealing from the academy. Without hesitation, Twilight bent over and gently inserted the seed into her passage. She clenched down on it several times to make sure it was snug, and to enjoy the pleasant fullness.

Careful to clean up the lab before set back out to return the flower to the librarium, she put away all the instruments and closed up her notebooks and put them away. She also opened a window to let some of the smell fade. As she walked along the halls, she savored the feeling of each step shifting the seed inside her pussy a little bit, causing her to clench down on it with her over sensitive walls a little and happily swished her raised tail back and forth, helping to spread out the scent of her musk coming off her soaked hind quarters and dripping snatch.

She couldn’t wait to get home and plant her very own flower.

Author's Note

Hey everyone. Thanks for dipping into this. I already have another chapter written and I just need to go over it and make sure I am happy with it. Unfortunately, the second chapter will be a little lacking in tentacle fun but will include exhibitionism, public masturbation and several other masturbation scenes with lots of detail. Tentacles will return in chapter three though along with lesbian tentacle sex. This story likely won't run more than four or five chapters. Thank you again and feedback is always welcome.
