I was practically skipping while travelling through Twilight’s Castle corridors, not being this happy in months, if not ever. The image of a naked Starlight is burned in my brain. I felt my dick harden as I remembered her voice. “Best day ever!” I cheered happily before I slowed down to look at my map.

“Turn to the left in the intersection, big door gives it away, got it.” I said to myself as I read the note about the library. After doing as specified, I found a very big set of double doors, almost big as the castle entrance. Inside was a lot bigger than I was expecting, dozens of bookshelves nearly reaching the ceiling, having numerous mobile ladders to reach the upper sections. There were circular wooden tables with crystal-framed couches, long crystal tables with numerous instruments on them, some looking straight out of an alchemist lab, while others looked more sci-fi, with glowing rune buttons, flickering lights and pulsing crystals. A white board is also there, but without any marker holders.

Twilight was operating one of these more advanced machines. It is a white wheeled monolith with my height, a metallic black screen that Twilight is using, many lights and a crown-like device connected to it. She mumbled to herself before she stopped and turned towards me.

“Ian, y-you’re already here!” Twilight seemed a bit surprised at my presence.

“Yeah. What is this thing?” I asked while pointing at the machine that she was using.

“N-nothing! I-I mean, we are going to use it later, but not now!” She nervously laughed before clearing her throat, “I need to do some tests with you after the class- I mean, a-after teaching you the basics of my world and-”

“Don’t need to sugarcoat it, Twilight. School wasn’t cool to me, but at least you’re a hot teacher!” I happily said to her while taking a seat as I chuckled at her blushing and sputtering before she stopped abruptly to sniff. She closed in on me, sniffing harder before her horn glowed and a wave passed over me.

“D-did you and Starlight have sex?! I can smell her on your body and your Aura is disturbed! T-this is going to complicate things…” She exclaimed with a few of her hairstrings popping in disarray. She mumbled a bit before they returned in place, “Don’t worry, I have something that might fix things…”

“What do you mean-”

“I said don’t worry!” She said firmly before taking a breath to calm herself.

“Okay! Let’s get started.” Twilight's horn glowed again, the whiteboard starting to display images, specifically a world map, full colors. There are three continents, a distorted America, a distorted Europe with some parts of Asia missing, and a larger continent under them. There are also many isles. “These are the main land masses of Equis. We are currently in Equus, and the nation of Equestria.” She used her horn as a laser pointer on the first continent, “To the north we have the Crystal Empire, one of our biggest allies. Northwest is the Changeling Lands, we are in a cold war with a ceasefire treaty.”

“The second one is the continent of Griffonia, with the biggest kingdom being the Griffonian Empire, the home of the Griffon race. The third is Zebrica, the biggest nation is the United Zebrican Tribes, the home of the Zebra race.” She said while pointing at the respective masses.

“Now, on to the different races that are commonly found in this world.” The images changed to five mares. A unicorn that looked like Starlight, a generic pony without any special trait excluding her broader frame and muscles, a slim pegasus, a weirder pegasus that had bat wings instead of feathered ones and prominent canines, and an alicorn that looks like Twilight.

“These are the three main tribes, the lost tribe and the Alicorns. Unicorns are ponies that can cast a broad choice of magic using their horns, having s-slightly more gifted assets than the rest. Earth Ponies are stronger and sturdier, being able to break rocks with bare hands and cast earth-related magic, even for farming. Pegasi are slimmer and faster, being able to move at sonic speeds and cast weather and wind related magic, they normally control Equestria’s weather.” She explained before her voice turned a bit saddened, “The lost tribe are the Thestrals, commonly called Batponies. They can fly like pegasi, but can’t cast their normal magic. Instead they have shadow-related magic and are able to feed on meat. They splintered from the other tribes after a tragic incident with the Moon Princess, Luna.”

Her voice took a more happier and majestic tone, ”Alicorns are the fusion of all three main pony tribes, having their powers on a much heightened scale. Their lifetimes are nearly immortal, some don’t even age, and their...breasts and rump are bigger than all ponies. There are only five living alicorns, and no prior records of more. Me, Luna, Celestia, Cadance and her daughter Fluffy Heart, all are considered royalty as Princesses. And no, there are no male alicorns. It was a miracle that Cadance had a daughter by using an experimental potion with her wife, and my sister, Gleaming Shield.”

“Princess Celestia and Luna are considered deities due living for an entire millenium.” I was shocked at this fact being revealed, “They move the Sun and Moon every day and night, although,” Twilight moved closer to me, “It is actually a lie. Equis moves around the Sun and the Moon moves around Equis, don’t tell anybody about this, especially the princesses.” I grinned, motioning a zipper on my mouth.

“Continuing on!” The images changed to five creatures. One looked like a pony, but with bug wings, a crooked horn, many holes on its legs and wings, and being fully-black with bluish eyes. The second is a woman with wings and cat feet, her hands looking a bit like a bird leg, and she stood nearly as tall as an alicorn. The third looks like a dog woman with dark blue skin, dog ears on top of her head and a spiked tail. The fourth is a Zebra looking like Zecora. And the last is a dragon woman, but she is taller than an alicorn.

“Changelings are a very curious race. They can fly and use magic like unicorns, with a very special magic of transforming into other races and mild mind manipulation, making them perfect infiltrators. They also feed on other races' emotions, like a parasitic species, especially focusing on love and lust.”

“Gryphons are an omnivorous race with a very low capability for magic, and an insatiable lust for gold and treasures. Making up for their lack of magic, they developed a unique style of enchantment. Dragons are similar to them in the aspect of greed, but they are able to breathe multiple elements, most commonly fire. Some are capable of using magic. Spike for example, can teleport letters using his fire.”

“Diamond Dogs are also similar to the previous two, although they are more loving of crystals and gems, having an incredible strength focused on digging and excavation with their cities being mostly underground. Zebras are a distant cousin of us ponies, but they are incapable of using magic, making up for the production of powerful potions, charms and amulets.”

“And before you ask.” She changed the images to a single one, a world with waves flowing through and around it. I was surprised that she could do animated pictures. “All races draw magic from a fundamental force called the Thaumic Field. It is a flow of mana that comes from the planet and beyond, flowing through us all.” The image changed to a crystal and something that looked like a geyser, “Sometimes it can crystallise into gems or flow in a more focused way in the form of vents, generally spewing many gems before disappearing.”

Twilight changed the image to a unicorn mare with similar waves flowing through and out of her, “This is called a Thaumic Aura. It’s how the Thaumic Field interacts with your body, letting you use it in different ways; like casting spells.” The image moved to the mare levitating a crate, before returning to the idle one, “Although it can be affected and interacted with in a myriad of ways, such as enchantments, training, potions and the emotional state of the user, more specifically, t-the person’s desire and libido, or h-her sexual state.” The image changed to the mare fingering herself, the waves erratically moving around her, “The l-lust can make you more vulnerable to spells and attacks, speaking of which.” The image changed to another mare wielding a sword, swinging at the first mare. The sword phased through her, and the energy waves rippled and slowed in movements. “Any movement that means harm to the user instantly changes to the Thaumic Aura as damage. If you take too much damage, you will be incapacitated at the mercy of your opponent.” The image turned into the second mare attacking until the unicorn fell on her knees exhausted, then the mare proceeded to sixty-nine the unicorn without resistance. Twilight quickly dispersed it with her face red like a tomato.

I was a bit out of words, to say at least. I wasn’t just teleported into a fantasy world full of hot women, but a fantasy world full of hot women with magic directly related to sex and without violence. Twilight continued in a very serious tone, “I have a thing to tell you about where you come from. This doesn't leave the room, don’t even tell Starlight, understand?” I nodded with a serious expression.

Her horn glowed and she locked the library door loudly, the image turning into multiple circles with small lines connecting them, “These are the Planes of Existence. We currently reside in one of them, and you came from a very different one.” One of the circles was much more distant to the rest, with very faint lines connecting to others. “You can see them as alternate dimensions. This isn’t general information, but the following is ultra-secret, for Celestia's and Luna's eyes and punishable by banishment to another Plane.”

“There is an event happening with all Planes. We don’t know how it started, or who made it start, or how to stop it. The Planes' connections with each other are strengthening, causing unknown races to teleport between them. Sometimes it's random like your case, but… some aren’t. This event is also changing each Plane, one after another. It starts small: violence starts to decrease, magic starts to appear, females start to become more frequent than males, their height and assets become bigger. Then, the Aura and Field of each Plane starts to distort, the general libido of everyone heightens, and sex cults start to appear. After this, the Planes connections start to become stronger until permanent portals open.”

“The second stage can make entire Planes fall into lust and depravity, and sometimes races want to spread it to other Planes. They start to use the portals, or even force them open to invade other people realms, to rape and steal their males, or even females. Celestia and Luna had suffered some of these invasions, even I heard about one in my lifetime. They made some kind of barrier that diminished the libido of the populace to a less extreme level, alongside shielding against invaders. But it seems like this barrier is starting to wane.” She illustrated everything with the images, before setting in a figure. She looked like a generic succubus, with bat wings, spaded tail and horns. “This is one of the races that invaded us, calling themselves Demons. They wielded magic that directly affected people's lust, and preached the word of a ‘Demon Lord’ and her gifts, being members of a ‘Cult of the Demon Lord’. Celestia said that they are heralds of the event, which they called as ‘The Sundering’.” She explained before dispersing the images, “That is all that we know.”

“This is why we can’t help you directly to return to your home Plane. You could open a hole for this Cult to invade yours and mine dimension. I-I’m really sorry..” Twilight said in a sad voice, tears forming on her eyes.

...No, I will not let them.

I used my finger to wipe away her eyes and give a brief kiss on her lips, she squeaked in surprise. “Don’t be sad, Twilight… I…I kinda like it here. I want to try to settle in first.” I whispered to her before continuing, “I’ll not lose hope. We need to find another way to return to my dimension, but without an army following behind me. I don’t want to lose my possible new home.” She and I smiled warmly before we kissed once again before quickly separating.

“T-thank you Ian…”

“No problem.”

I looked around, “What do we do now?” The room had become a bit somber at the serious information that Twilight gave to me, but it quickly brightened with my kind act.

She smiled widely, “I’m happy if you asked! We need to do some tests with your Thaumic Aura, that kind of test.” Twilight blushed a bit while teleporting the board away and summoning the paper that she received from Mayor Mare, “This is a chart about your personal information related to sexual stats and Aura. I know that you already had sex today, that’s why I have this.” She summoned a small greenish potion before levitating it to me.

“This is going to replenish your reserves to normal levels. Don’t worry, it isn’t bad-tasting.” She assured me. I shrugged, uncorked the bottle and chugged it down. It tasted like green apple, but with a hint of viscosity. After everything went to my stomach, I already felt more awake, like I had eaten a coffee candy.

“Wow, this thing is really good!” I complimented while the energetic feeling dissipated.

“You’re lucky that I had this. It is a rather expensive semen replenishment potion. Although Zecora might be able to make more…” Twilight trailed away, mumbling possible transactions with the zebra.

“Yeah, Starlight would love for me to have some of these. Oh! Speaking of Zecora, could you invite her someday?” I smirked devilishly, “I need to repay her favor, after all. I don’t like to be in debt with someone.”

“O-of course. S-she will be m-more than happy to come here.” Twilight stuttered with her cheeks darkening, “A-anyway, let’s get started. The first ones will not require any interaction, just scans from the machines.”

We started to perform the tests after I stripped, and my excitement to use highly advanced machines quickly boiled down to boredness. Standing still while energy or a laser passed over me, jogging on a treadmill, having my knees tested with a small hammer, having sexual thoughts while using a weird helmet, the last one was rather easy with the drop dead gorgeous alicorn in the room, all while she filled out the form.

“Alright, n-now are the ones that require the disturbance of your Aura. Are you ready?” Twilight asked while her cheeks darkened even more.

“More than ever.” I answered with a grin.

“G-good.” Her horn glowed and an articulate bed appeared, looking a bit like a surgery bed but much more comfortable, alongside a series of scanners, including a small one for my head, “Lay down there a-and I’ll do the work.”

I did as ordered, my heart pounding on my chest, “S-so you will be riding?”

“W-w-what?! No! I-I mean, no. I will u-use my magic for it. D-don’t worry, it will be like a real thing.” She said with her entire face and a bit of her neck becoming hot red, although I could see her lower lips moistening a little. Twilight moved to a machine linked to all scanners, “S-starting, just relax.”

The alicorn horn glowed, and her light engulfed my cock. It looked a bit weird, but I instantly moaned as the sensations started. It was like a delicate hand started to work out my shaft, while another one gently massaged my balls. The pace started very slow, but quickly sped up with my more frequent and louder moans accompanying it. The spectral hand occasionally shifted, tightening and releasing as if it was milking my cock, gaining a vibration effect or adding a left and right movement before it stopped altogether.

“N-next phase.” Twilight informed, a smile had formed on her lips with a familiar glint in her eyes.

The glow intensified and my breath hitched, the feeling of something warm, hot and wet slowly enveloping my dick all the way to the base, “T-t-this i-is the f-feeling o-of a pussy~?” I shakily asked and Twilight nodded. The spectral vagina started to go up and down on my shaft, gaining a vibration effect just like before. It felt absolutely heavenly, and I subconsciously started to thrust, the alicorn adding bindings on my arms and legs for me to support myself.

“Ooh~! F-fuck!” I moaned out loud as my cock was magically fucked by Twilight, its furious throbbing signaled my incoming orgasm. I barely could react before I unleashed one of my biggest cumshots, the spectral vagina tightening around my penis to milk it. My toes curled, hands clenched and eyes rolled back, semen gushing out in long bursts and pooling in a floating sphere, “Ooooooooooooooooooh….~” I let out a long groan before laying limp on the bed like a puppet with its strings cut.

With my eyes half lidded, I could see the subdued hungry look of Twilight while she looked at my deflating cock. She shook her head before summoning a glass jar and filled it with my semen, while using a pen to fill out the form and releasing my bonds.

“O-okay, we are finished here. A-are you alright?” Twilight asked me with some concern, the form, pen and jar disappearing while she cleaned and dressed me.

I waved her concern off, “I’m fine… J-just give me…give me a moment..” She nodded and went unsummon the numerous machines in the room while I was taking some time to rest and even my breath. A few minutes later, I was good as new after getting a wild round of magical sex.

After I managed to get myself together, I walked to Twilight, who had finished her cleaning, “Am I good to go, Doc?” She flashed a smile at me which I replied with a grin.

“Yes, but I recommend you to take some self defence classes. I know a few ponies and guardsmares that can teach you for free ANDPrincess Luna might also help so I will contact her. She’s a bit of a combat enthusiast…” She sheepishly chuckled before continuing, “Try to find Rainbow Dash and Applejack in town. Rainbow will be very easy to spot, so she might crash on you anytime. Applejack wears a cowgirl hat and has an apple themed cutie mark, you might find her in her family farm, Sweet Apple Acres, beside the town.”

“Alright.” I nodded, marking off these locations and people on my mental notepad, “I will go explore a bit and try to find them. See ya later Twilight!” I told her before heading to the exit while waving.

“S-see ya!” She stammered with her face red and body trembling a bit, I only saw a brief movement of her hands before I closed down the door, hearing some strange sounds coming from inside, wet sounds, but it was mostly muffled by the library door and walls thickness.

I smiled to myself while walking on the corridors, finally free to do what I wanted. Before rounding up a corner I heard the sounds of hoofsteps and very low giggling, before my good mood became even better with the sight of Starlight rear up and high, she bending down to pick up something, her tail hiding what it was. She wiggled a bit her rear, I knew that she was doing that on purpose, so I decided to follow her clue.

I slowly approached her, barely trying to hide my sounds before I raised my hand and gave her ass an absurdly light smack, having enough force only to make her rear jiggle. She yelped and moaned lightly before turning to me, “Atta boy~ Attacking a Princess apprentice when she is vulnerable?” Starlight teasingly accused me, “You might need a punishment for such offence~” Her horn glowed a bit menacingly.

“Maybe later, Starlight.” I ignored her threats and went for a quick hug, she leaned down to give me a kiss on my lips, “I have to explore the town a bit, needing to meet some people.”

“Don’t tire yourself out by wandering all day, you will need energy for tonight.” We briefly enchanged kisses and light gropes before separating, “And don’t get in trouble. Celestia knows what can happen with you in this crazy city. Avoid Pinkie Pie, the Pink Terror, and if you can’t, don’t try to understand her. You will get the idea when you see her.” I looked at her a bit confusedly, but I decided to take her advice.

We exchanged our goodbyes and departed in opposite directions. Even with the castle drinking fountains, I was already feeling tired by so much walking, but I’m surprised at not being an exhausted mess, my cardio really had been improved. “Heh, magic…” I murmured the only explanation of these sudden changes.

Half an hour of walking later, I was outside the castle feeling the afternoon sun shining over me. Breathing in, I smelled the evergreen without pollution, heard no car and city noises, only the rustling grass on the breeze. But then, a loud whistling accompanied by shouting, the problem is, it was coming from above.

I looked up, barely seeing a multicolored blur with a bigger predominance of pale cerulean coming down before a gust of wind hit me and the blur crashed on my body, the both of us skid a few meters in the grass before falling in a tangled mess.

The blur was actually a pegasus mare with a tomboy look. A medium-length mane with all colors of the rainbow in a wild style with a single bang, being much more frazzled due the fall. She was lean, with an athletic body bare of any fat, her breasts much smaller than Starlight and Twilight, but still being big enough for a boobs guy like me to enjoy, “Rainbow Dash, I presume.” I called her while I groaned.

She looked dizzily at me before narrowing her eyes, “You!” Rainbow Dash shouted before planting her palm on my face, pushing my head down before skillfully disentangling herself and pinning me in the ground. I already could feel a very good apprenticeship being formed.
