A Slight Conundrum... for Science!
"Huh," Twilight mused as she looked at the box curiously. One, which upon first glance, had no real significance... it was just a box. With the Royal Seal Princess Celestia herself sent to Twilight. It infuriated her not to know what was inside, an untold mystery. Along with the box came a scroll, and the scroll read: "Have some fun with this, I know you will..."
Is this a good idea? Probably not, but there's only one way to find out.
Twilight opened the box, and inside it was a book. Not just any book, but a spell book. One filled with the arcane magics that made Twilight go into deep observation mode. One that needed to be examined further, and for its magics to be used. Twilight hummed a little tune to herself as she casually strolled down to her basement.
Twilight locked herself downstairs, in order to not be interrupted by Rainbow Dash again, or Pinkie Pie whilst trying to figure out what this mysterious book's secrets were. Was it a book with knowledge that nopony had seen before? Or was it magics that had long been forgotten? It certainly had a "musty" look to it. The pages were slightly dusty, the cover had a thick coating of dust making the title unreadable without cleaning it first, and the binding was slightly falling apart.
"Why would Celestia give this treasure to me?" Twilight pondered.
"Summoning: A Comprehensive Guide to the Ethereal Realms"
"Chapter 1: Simple Summoning"
Twilight promptly read this chapter, and decided she had already known most of the knowledge here, and also read the next 5 chapters before stumbling upon the final chapter:
"Chapter 6: Carnal Castings and Final Words"
She fumbled back a bit, and started thinking of all the things that could go wrong if she tried any of the things in this chapter. All the rest of the things she had summoned hadn't been all too bad, but these could go horribly, horribly wrong. She could be incapable to send these back to where they came from, and unlike the other summonings, they could also control her and use her to breed with every mare (and stallion) in Ponyville!
Despite her many doubts, Twilight decided to give one a whirl anyways.
"For science, right? What could possibly go wrong?" Twilight exasperated.
She looked at the first summoning in the chapter: Tentacles. She gulped and thought to herself, "Why would this be in this book?" She created the circle required for the summoning, and her horn lit up as she said the incantation: "Erusaelp lanrete rof ,em nommus!"
The incantation and the magic combined had caused the circle to glow and animate, and Twilight shrunk down in order to not be near the circle in case the tentacles decided to do things without her consent. However, only about 7 or 8 tentacles were there, and they were all relatively tiny.
"Hey little guys!" exclaimed Twilight, "I have summoned you, and I would like for you to acknowledge this fact."
The tentacles then nodded in synchronization, recognizing Twilight Sparkle as their temporary Master.
Twilight then heard a mysterious voice in her head saying, "Come closer... we won't bite..."
Twilight was drawn in by their mysterious means of communication... then suddenly, she felt 4 of them hold upon her hooves. Twilight gasped and fought back, but the tentacles wouldn't let go. Their grip was too strong for even the Alicorn's magic, for the tentacles could not be targeted by magic of any kind (Dark, Chaotic, or regular old magic), for their powers were of Tartarus, the realm of all things sexual and lust-induced. Not wasting any time, more tentacles appeared, some as big as Twilight's hooves, and some shaped oddly like drills. Twilight, herself, was confused about this development, but soon realized it too late.
The tentacles soon grasped Twilight all over her body, surrounding her torso, her wings, her hooves, her horn, and her tail held high. She blushed as she realized her compromising position, seeing as her entire nether region was available for the using. Twilight was glad she had locked the door, because if Spike had walked in, sweet Celestia that would've been awkward. As the tentacles took hold of Twilight, she felt one of them poke against her marehood, waiting for her to calm down, as they sensed that Twi, true to her looks, was a virgin. As the tentacle slowly pushed into her marehood, another drill-shaped tentacle came close to her virgin ass as well. Seeing as how it was planning on shoving itself into her full-force and then start rotating, it gave Twilight shivers and caused her to tense up. Seeing as how Twi had just tensed up, the tentacles applied lube from itself, preparing to give Twilight her very first anal and proper fucking.
"No, please don't do this to me, I was waiting for my -"
Twilight was cut off by a very large tentacle boring its way into her mouth and deep into her throat, causing Twilight to gag upon the intruder and clenching down upon the two at her rear entrances. The drill-shaped tentacle started rotating and pumping itself in and out of Twilight's ass, causing pleasured moans to come out of her as the tentacles began to fuck her harder in the ass. The one in her pussy pushed in slowly, as to make the pain of breaking her hymen as painless as possible. Twilight knew this, and she thought she would have at least a stallion take her first time, not just some stupid little tentacle! However, she could do nothing about her current predicament, and succumbed to the pleasures assaulting her ass, pussy, and mouth all at the same time. The tentacles, sensing her relaxing, took on a more ruthless form of fucking, pushing in and pulling out faster and faster, causing the mare they were pleasuring to moan as if she were in heat.
Soon, as if on queue, the tentacles were reaching their climax and so was Twilight due to her first time ever having sex. As Twilight's peak was incoming, the tentacles in her mouth and marehood started squirting their juices down her throat and pussy. The liquid coming from the mouth tentacles was an aphrodisiac, in order to keep her aroused for a round two, and the one in her marehood preparing her for the incoming plan they had for her: a host for their eggs. As Twilight came, the tentacles began to lay their eggs into the recipient of their fucking, despite Twilight never even noticing whilst being upon her first orgasm with something in her pussy. Her ass and marehood clenched down upon their intruders, and she let out a lusty moan. Why in the name of Celestia would aforementioned pony send me this? Twilight pondered as she was overtaken by bliss, and a new wave of lust as she noticed she was being pumped full of eggs. As the second, third, fourth, fifth, and sixth eggs were pumping their way into their mother's body, Twilight was getting nothing but pleasure. She felt full, and also started to look pregnant already with six eggs already inside her body. However, there was much more that the tentacles were planning to do upon their "willing" victim. As Twilight felt the two tentacles leave her body, the one in her mouth gave her more fluid that sent her world spinning and set her marehood on fire.
Another tentacle, similar to the one just in her vagina, slithered its way into her abused asshole and started smearing fluid all along the inside of her ass, preparing it for the insertion of even more eggs. As the eggs slid into Twilight's ass as well, she decided that she would give up thinking and just enjoy the pleasure of the eggs sliding inside her. Her rational mind was screaming that this was a terrible thing, but her lust-filled mind backhoofed her into submission and said to shut up and enjoy this. Twilight's stomach inflated to look like she was ready to birth triplets with all the eggs she was carrying, and the tentacles deemed they were done here. They tapped into Twilight's magic, closing the portal through which they entered, leaving Twilight in an awkward position with her womb and ass filled with eggs, and Spike upstairs. After feeling the effects of two orgasms in a row, Twilight was slowly dozing off...
How in the name of Celestia am I going to get away with this? Twilight wondered, and slowly fell asleep downstairs.
Little did she know, she was being watched very intently by somepony that already knew the pleasures that this book could bring...
