Author's Note

The Two Twilights is the first Challenge story that I've written. My first Blind Box pulls were a regular Alicorn Twilight Sparkle and a Black Alicorn Twilight Sparkle...oh this is gonna be fun... Anyway, this chapter contains scenes of a sexual nature without there being actual sex, and will include Bondage, Chemical/Drug use, Forced Impregnating and Questionable Use of Science. If you have no problems with that, then read on, otherwise, you clicked on the wrong chapter.

First Pull: The Two Twilights

The Two Twilights

Twilight Sparkle slowly regained consciousness as the room spun back into view, her memories starting to come back. She had been returning from the market after an experiment failed in her lab at the castle, she walked in the door and then…everything went black. Looking around, the lavender Alicorn quickly identified the room she was currently in, she was back in her laboratory, deep in her castle’s sub-basement. All of her personalized equipment that had been painstakingly salvaged from the old Golden Oaks Library and meticulously repaired by her own hoof was within her sight, all in their proper place. That fact brought some calm to the young mare’s mind as she started to get up from where she lay, and found herself unable to.

“What? What’s going on? Spike, is this some kind of joke?” Twilight carefully tested her every limb, but she was firmly bound to an examination table with magically hardened metal shackles around her fetlocks, ankles and wings. Further investigation revealed additional restraints around her neck and just under her ribcage, ensuring that she could not move a single inch. She attempted to light her horn, but the feedback she got when the attempt failed suggested a magic suppressor ring, indicating that she was completely helpless. With her limbs in a spread eagle position on the tables, the Alicorn also realized that she was completely exposed as well, and what calm she was feeling quickly evaporated, despite the order and science that surrounded her. “Spike! This isn’t funny!”

“Spike can’t hear you right now Twilight, he went over to Carousel Boutique about an hour ago to assist Rarity with her dressmaking..” Twilight froze the new voice spoke. It sounded vaguely familiar, but she was having trouble placing it. The voice sounded like it came from a mare, her tone was condescending with just a hint of snark and far from being warm or friendly as it continued to speak. “So for the time being, it’s just you…and me…” the table Twilight was bound to began to tilt upward to a forty-five degree angle, letting the lavender mare see her captor for the first time. The mare’s coat was dark, practically black, save for her mane and tail which were very familiar to Twilight and made her realize why this mare’s voice sounded so familiar. Her mane was a three tone purple, exactly like Twilight’s. Even the mare’s Cutie Mark was identical

“You’re…you’re…!” Twilight felt her eyes widening as she tried to find her tongue to give voice to her amazement. The other mare simply nodded.

“I’m you, well, not quite you. I’m from what you might call an anti-universe to your own, the result of your little experiment earlier. You may refer to me as Twilight Shadow, or for the sake of convenience, simply Shadow.” The now named Shadow walked slowly around the chamber that contained Twilight’s lab, almost marveling at the crystalline architecture. Twilight, meanwhile, was marveling at Shadow’s admission, still, the mare’s manner was disconcerting.

“So, what do you want? Why did you…?”

“Tie you down like a specimen in your own lab? It’s quite simple Twilight, because that’s exactly what you are right now. I have a little experiment of my own that I’ve been meaning to conduct. I simply required the right test subject to see if my theory was correct, and then you opened a breach into my world by sheer accident and gave me the opportunity I required.” Shadow was smiling at her now, but it was a cold smile, and it made Twilight almost feel dirty the more she looked at it.

“W-what exactly do you mean? What theory and what is your experiment?” Shadow regarded her for a few moments, still smiling that cold smile, before she finally answered.

“To understand my theory, a little background is required. You see Twilight, everypony in my world is completely sterile, and incapable of breeding. We have survived only because we developed the magic and technology to clone ourselves and manipulate the DNA of those clones, literally building our own foals from the ground up. Only now, many of the DNA samples in our cloning banks are beginning to degrade and become unusable, so we face something of a crisis.” Shadow trailed off as she began to gather a few objects beyond Twilight’s sight, before coming back into view again. “I had the theory that it might be possible to breed a solution to the problem, literally rewriting our genetic code. The main problem I encountered was that the cloning tanks couldn’t handle growing the new life form that would be required to alter us, so I thought, why not take a more…natural solution? Of course, this would mean finding a mare who could not only withstand the about of raw magic that was required, but also one who could breed.”

“But you said that nopony in your world could breed! That would make your efforts completely pointless!” Twilight sympathized with Shadow’s plight to a degree, but she still had no idea what this Dark Mare was planning.

“You are right of course, no mare in my world can breed, and even if we could, I deduced that I was probably the only pony who could even hope to withstand the sheer level of magic this experiment would require. That is why I was quite pleased to be brought into this world, you have an ability that I do not and cannot possess. You are exactly what I need to save my world’s ponies from the death of genetic fading that has all but destroyed our cloning banks.” Twilight's eyes widened again as she realized what Shadow was saying, connecting the dots faster and faster before Shadow even spoke her next words. “You will be the mother to our saviour.”

“WHAT?! I…I can’t! There’s too many variables, to much that could go wrong, not to mention that you haven’t exactly conducted yourself in a manner that’s even slightly trustworthy!” Twilight started to struggle against her bonds again, even knowing that it was useless. “I’m too busy to be a mother! And too young besides, let me write to Princess Celestia and maybe we can find another wa-“

“There is no other way Twilight, and I wouldn’t trust Celestia in a million years after what she did to my world. I will perform my experiment, save my ponies, and you are going to help me do that…” Shadow began to set up some kind of equipment around Twilight, magically stuffing a ball gag into the lavender mare’s mouth and tying it in place as she did so. Before long, Twilight had what appeared to be a long, ribbed shaft on a piston connected to the base of the exam table and aimed at her marehood while Shadow attached some kind of canister filled with a thick white liquid that glowed with a faint indigo light. Despite the situation, Twilight couldn’t help but wonder about the fluid and the apparatus that Shadow was using, as well as what her method of testing would be. Shadow, perhaps noting her interest, began to explain.

“Based on my research of this world, I’ve tried to design this experiment to at least be pleasant for you, or as pleasant as I can make it. The shaft is my best approximation of what would not only sexually stimulate you, but serve as the delivery medium for the mixture in the canister, which is an amalgamation of Spyke’s potent Dragon semen, Gryphon semen acquired from the Gryphon Emperor, and both my and Queen Luna’s Alicorn magic. After you are adequately prepared, we can begin…I might even take that gag out so you can comment and provide feedback if you promise to cooperate.” Shadow picked up a syringe filled with a faintly glowing yellow fluid and a fairly long needle that made Twilight stare for a moment. Shadow glanced at it in answer to the question in her eyes. “Oh, this? This serum is one of the preparations I was talking about, it will be injected directly into your ovaries to trick your body into thinking you’re in heat. An additional injection into your mammaries to induce lactation will further this and supplement the child you are to conceive.” With that said, Shadow proceeded to do exactly as she proposed, her magic easily holding Twilight still and locating the exact spots on her belly to inject her serum into the lavender mare’s ovaries.

For Twilight, the experience was…uncomfortable to say the least. The secured mare was completely helpless to stop the needle from penetrating deep into her body however, or the emptying of half the syringe’s contents into each of her ovaries. The process with her modestly sized udders was the same, though the needle wasn’t as long. Some minutes later, Twilight started to feel the effects of the two serums, her udders felt suddenly heavier and had grown a little larger, as well, her marehood had begun to drip with arousal in her induced heat. Shadow nodded in satisfaction as soon as she saw the effects and turned on her apparatus, pressing the phallic substitute into Twilight's marehood. The young alicorn had to admit that it didn’t feel that bad to be penetrated this way, Shadow had done her research well in that regard. Twilight’s body even gladly accepted the invader and the pleasure it was bringing her, anything to satisfy the now needy mare’s sexual drive. The fact that the shaft was starting to inflate some kind of ‘knot’ seemed to only heighten her pleasure every time it bumped into her pussy lips every time it was thrust into her body by the piston. Shadow increased the speed of the piston’s thrusting slightly as Twilight neared her orgasm, the pleasure all but overwhelming her mind before the fully inflated ‘knot’ of the shaft was slammed into her pussy and triggered her climax, causing Twilight to scream her pleasure as loudly as she could.

A minute later, as she rode out the bliss of orgasm aftermath, she felt the first jets of the semen and magic mixture being pumped into her womb. It brought an odd smile to the tired mare’s lips. Perhaps it was just the orgasm talking, but Twilight somehow knew this would make her become pregnant, and she was coming to terms with that. More and more of the mixture was pumped into the mare, bringing a warm feeling with it even as her belly began to balloon with the sheer amount. It was an odd feeling, having her body already looking about four months with foal, then five…then six…but Twilight’s mind didn’t seem to care at this point. Maybe she would have more time to study it after the baby was born…
