“Mommy! I want that one,” Essence said, pointing at the book behind the glass case.

“Now?” Radiance said in a sharp whisper. “Out of all places and all books? You decide to pick that one.”

“You said that I could have any book that I wanted. Any of them. And that’s the one I want.”

“I know I said that you need to read more, but that’s not the kind of book you should be reading.” The crimson cover had a large pink heart on it; titled Erotic Exploration for a Magical Mare. She shook her head. “You won’t like it and-“

“Please, Mom. I’ll read it every night just like you asked. I’m not too sure what it’s about, but if it’s in one of these places that you like so much, maybe I’ll like it too. Ooo! Maybe I might get my cutie mark from it!” The filly said, looking at her rear and spinning in circles as she imagined the possibilities: maybe of watching TV… or a weird snake… or something else entirely! Who knew?

Her mother winced at that, staring at the book like she was waiting for an easy answer to show itself. Sighing heavily, she looked at the shopkeeper who was eyeing the two of them suspiciously. “Uhh… you know that’s not really a book for a foal, right?”

She nodded and said as flatly as she could. “I know… but I’ll take it.”

With a shrug the shopkeeper opened the glass case, pulling it off of its tiny crystal bookstand.

“Alright, and with the bottle of Slide ’n Glide and 10-sparkles battery, that comes to 52 bits,” he said as he started to put everything in a black paper bag; the front having Toys ’n Us store logo written across the front.

“She needs to read more, so it’ll be a good place to start if she’s excited… for reading,” Radiance said with an awkward smile on her face as she reached into her saddlebag to pull out her coin purse. The storekeeper only nodded along as he watched her empty the bits onto the counter. “Plus I did promise her any book, so I need to honour my word.”

“Mmhmm,” he said with a few nods as he counted the bits into neat stacks, before pushing a few remaining back as change.

“Maybe she’ll enjoy, uh… whatever’s in it. Maybe she’ll… uh…”

“Get her cutie mark?” the shopkeeper added, watching the mare’s face turn bright red.

She winced again at that as she looked back to Essence, who had caught her tail in her mouth. “Y-yea… her cutie mark.”

Essence saw the black bag and her eyes lit up. “Thanks, Mom!” she said as she started to walk out with her mom, before turning back and waving to the shopkeeper. “Oh and thanks, Mister!”

“Our pleasure, we’re glad you came!” the shopkeeper said as he waved, Essence only giggling at the standard goodbye he said to everypony.

Mom had taken a while to give her the book, even as she patiently waited all day to read it. ‘When we get home’, became ‘after dinner’, to ‘later tonight’. Well it was later tonight, in fact it was bedtime.

“Goodnight, Sweetie,” Radiance said as she started heading to the door after tucking Essence in for the night.

“Moooommm…” the filly whined and fidgeted around in the bed. “Aren’t we forgetting that I still need to read today?”

“You can do that tomorrow. It’s already your bedtime.”

“But then I won’t get to read today!” she said with a huff. “Then I’ll be breaking my promise. I said that I needed to read every night once I picked out a book. And well… now I have, and you’ve been saying later all day today.”

Her mother stood there thinking until she finally relented. “Alright, fine,” she said with a sigh before looking a more little determined; the same kind of determination that she had when she made the original deal about any book. “I’ll go grab it and you can start reading it. But! Like you promised, an hour each night until it’s finished. And then we’ll get a new book after that for you to continue.”

“I promise,” she said as she crossed her heart, sitting up on the bed with a big smile.

Her mother headed downstairs to the kitchen where her saddlebags were; almost everything was unpacked except for the still untouched paper bag. But soon enough, she walked back in to the Essence’s room and placed it on her nightstand before quickly heading back out and closing the door without saying another word.

Essence waited for her mom to leave before diving over and grabbing a hold of the crimson book. It had thin velvet over the covers that held the deep golden coloured pages within. The strangest thing about it this thought was that the book was warm to the touch, almost like it was another pony that she was touching. Maybe it was magic? This certainly seemed to be a magical book, the title and cost alone was evidence of that; Mom didn’t usually get something this pricy until her birthday or the winter holidays.

But besides that, what was so special about this book? She opened it up to the start and the pages were oddly glossy, almost like she could spill a drink on it and everything would still be fine. The first few pages were the silly small-text legal info that seemed to be in every book, the table of contents, and then the actual introductory chapters.

A wave of reluctance went through her as soon as she saw the paragraphs, tempering the excitement she felt earlier. The realization came over her that she had to read through this entire thing, and it already felt like she was going to be clambering over a mountain to do it… plus she did promise to do so.

“Ok… well here it goes…” she said to herself as she started to read through a sentence at a time, getting passed each part one after another. Apparently, book was about improving a mare’s special alone time, with herself… or with others too.

It was weird that there was an alone time but yet could also be done with others… that wouldn’t make it alone time anymore. It didn’t follow up on that at all, instead mentioning that they would be starting with the basics and going from there. Simple enough that anypony with a horn could do it.

It was a good thing she had a horn or else she’d be out of luck for any of the magical things that it suggested. Plus it might be even better if this was a magic book that started at the basics. Even learning how to levitate things was quite a challenge when she did; the magic’s teacher always went too fast and kept saying how she should have learned some of this last year. Maybe this would be different?

She smiled a bit, thinking of the cool magic she’d be able to show off. It felt almost surprising to be looking at the page and feeling some excitement as her mind ran wild… and even more surprising to realize she was at the end of the whole page! It hadn’t felt all that bad, but there were still many more pages to g-

“Whoa...” she said out loud, as it wasn’t words she had to look over but a picture; more specifically, an entire full-page picture of a highly detailed marehood, all drawn with pencils. It had several labels pointing to each part: clitoris pointing to a large round pearl at the top, nestled between two thick lips labeled as the labia. Vulva was the outer parts grouped together, while vagina directed to the large inner hole that was spread apart for her to see deep down into. Even a pony’s tailhole was marked up with the specific parts right on the bottom, and the labels continued all the way down to their dock.

She stared hard at it, sitting up close until her muzzle booped against the page. “Ahh!” she squeaked out and slammed the book closed, almost like somepony was going to rush in here and catch her looking at a pony’s marehood. But even as she watched her door, breathing hard at the self-induced surprise, nopony came through to catch her.

She was all by herself, reading her book.

That wasn’t what she expected when she started this. She eyed the book suspiciously before working up the nerve to open it again, back onto that explicit page. It felt weird looking at it, almost like she was getting away with something she wasn’t supposed to. She could feel butterflies in her stomach and a nervous tingle from within the more she looked at it.

It wasn’t like she hadn’t seen the… she looked at the term… the vulva or labia parts before, but it wasn’t more than an accidental glance in public. The rest of the other parts she couldn’t remember ever seeing before, but it’s not like she had somepony to check this out on. She glanced down at the blanket where her legs were nestled under. She probably wasn’t flexible enough to look either.

What struck her as odd was just how pronounced everything was, like it was puffer than normal. Even from what she remembered from her mom, it was never that big. She blushed a little bit as she glanced under her mom’s tail in her mind. That would certainly get her in trouble if she actually did that, or even thought about it. Good thing Mom can’t read other pony’s minds… she hoped.

It was hard to look away from the entire mare’s crotch was on display. Studying every curve that was there and reading every label like she was studying for a big test… although she really hoped she wasn’t getting tested on this book. She’d probably die of embarrassment if she had to take a test on this in the middle of class... or if her mom was the one asking questions.

The diagram on the opposite page she didn’t recognize. It looked more like a biology diagram than anything else with its T-like shape, pointing out something tubes, cervix, and the vagina. That was new, but the words just kind of blended together and didn’t get more than a cursory glance.

She didn’t know why a book like this existed specifically about a mare’s private parts, but she wasn’t really complaining. In fact it felt like she was doing to opposite. It was only two pages in and it felt like she needed to read more and unravel the mysteries hidden within these golden pages. She grabbed the corner of the page, preparing herself to read and learn about whatever came next.

And with that she turned to the next page.

Author's Note

This was a fun idea that I had from my RP days many years ago, and was rekindled with a series of images on Derpibooru (NSFW 2514650). It isn’t foalcon in the image, and this story has no relation to it, but it did give me the inspiration to see what would happen if a filly gets hold of a similar magical book and where it would go from there.

I didn’t plan for this story to have an end, just have each chapter being its own special theme or idea. As such, this story will eternally be marked as incomplete, since I can always add more if something pops into my head.

I hope you all don’t mind an infinite story of a filly getting into more encounters with a very sexy book.

Please let me know if you liked any of the chapters in a comment, and follow if you would like to be updated for more.
