Life Lessons

Twilight Sparkle cocked her head at the book was reading, and then looked at her rump, then back to the book again. She discovered when she was a filly that if she was having a problem, reading on it was usually a good way to find a remedy; or at least to comfort herself with the knowledge on what the cause was,  and possible solutions.  The subject of her interest was sitting in front of her; a book titled ‘A Scientific Guide to Sexual Anatomy, Breeding and Reproduction in Equines”, as well as behind her; her rump.

It was midnight, and as of yesterday; she had developed an ever-present itch and swelling in her “privates”; as well as them leaking a strange substance, and she was now trying to discover the cause. The feelings weren't exactly painful, merely a mild to moderate itchy sensation; but it was starting to become a nuisance, even having awaking her up from her sleep.

After sending Spike off on some chores for the day, and giving him a few extra bits then for the required items for his allowance, (which he undoubtedly used to visit Sugar Cube Corner and the local gem shop). Twilight had also bought herself overnight; for after he’d returned from the shopping she also had volunteered him to spend the night watching over the Cutie Mark Crusaders (which cost her a large ruby she'd been saving for his birthday). Twilight now had the library all to herself, all night. Twilight had, wanting to discover the cause and cure for her unusual symptoms, grabbed the first book from the multiple stacks she'd recently borrowed from the Canterlot Library, and had thought would be relevant, and started reading.

Twilight had been sheltered by Princess Celestia every spring since she was a filly, even after moving to Ponyville. Every spring, Princess Celestia would send a carriage for her, and she would be brought to stay at the castle for a few weeks. She was treated as she always was; but she would never be allowed outside during this period, and all the male guards were strangely absent, replaced instead by a large magical barrier that prevented entry into and out of the castle. Twilight had also always been limited on her reading materials, and had never been permitted to the wing containing biological texts unsupervised. Whenever she complained of an itch or burning “down there” during her spring visits, Princess Celestia had always given her a potion every day, and it went right away.

Twilight remembered back to her springtime trips to Celestia’s castle, this strange scent being in the air for the whole time she was there. She also heard moans at night time, but when she went to check on the Princesses, she discovered their chamber doors were both locked. Defeated, she had gone back to bed. When she had asked in the morning why both the sisters had moaned; Celestia claimed to have stubbed her hoof, the pain so bad she moaned over it all night. Luna, with a blush, had said she had a severe ache she needed to take care of, eliciting a harsh glare from Celestia.

After Twilight became a Princess; Princess Celestia had removed all restrictions she previously imposed on her; telling her she was allowed to remain in Ponyville all year round,  and had also unlocked the entire Canterlot Library to her as a coronation gift, allowing her to check out whatever and however many books or scrolls she wanted…regardless of their content. The first place Twilight had gone was the previously-restricted biology section; the only section she had never really been given full access to before. Twilight had responded by checking out nearly the entire wing, curious about how the entire equine body worked.

Twilight cocked her head one way and then back in the other direction. Twilight lifted her eyes from the book, got up, and then started the pacing she was apt to in times of stress. After a few minutes, she flopped down on her hindquarters, but immediately shot back up; the pressure on her privates giving the burning sensation an unexpected boost.  “Dang it, I just know the answer to this feeling is in this book!” she commented, stamping her hoof.

Twilight turned past the introductory pages of the book, and was introduced to a diagram of a female equine’s reproductive tract. “So,” she said, lying down with her back legs spread, looking at her puffy slit, “this is my ‘vagina’.” She proceeded to look again at the diagram, the book now levitating above her, and read aloud the text: “The outermost part of a female's anatomy is called the ‘labia majora’..." she said, and, further looking at the diagram, she added, "...and past that the rest of the mare's 'privates'.” Feeling a shudder crawl up her spine as she experimentally poked her lips, she was struck by an idea. She levitated the book upstairs with her to her room with her magic; she then set the book on her dresser and lay down on her back on her bed, with her legs spread. She proceeded to use her magic to both move a full-sized mirror to the foot of her bed, and to close and lock her bedroom door. She’d need both the mirror and the privacy to allow her to do what she was about to do.

Moments later, Twilight shifted on her bed to lay on her stomach, sighing at the softness. When she shifted again, her pussy rubbed against the silken sheets, causing Twilight to jolt upright. Shaking a newly developed fog from her mind, Twilight then levitated her book-stand over to her bedside, and placed the book upon it. She opened the book, and turned back to the proper page with her magic. “It looks like the rest of this diagram is based past the labia…” she said.

She then proceeded to look at the mirror, and carefully spread her puffy lips with both hooves; eliciting a gasp from the inexperienced mare, and causing her head to press back into her pillow. “Oh...my…” Twilight gasped, the feelings unfamiliar but so inviting to her. She shook her head to clear it, and looked back at the book. “Ok, so past the labia majora is the ‘labia minor’…” Twi said, looking into the mirror at her spread pussy. After a moment of searching, she suddenly exclaimed “Oh, there it is!”, and proceeded to rub over it with her hoof, eliciting another burst of pleasure down her spine, and a moan.

Starting to feel warm, Twilight used her magic to open her window to let some fresh air in. Twilight settled back down on her bed again, and looked once more at the biology book. “Further inside, past the labia minor, is the entrance to the ‘vaginal canal’” Twi said, looking once more at her reflection. Twilight moved her hooves deeper into her pussy, biting her lower lip at the sensation it caused her. At this time, Twilight had noticed her ‘vagina’ had started to leak the strange, slippery, water-like substance en masse. Twilight collected some of it on her hoof and brought it up to her muzzle. Taking a curious sniff, she discovered that it in fact smelled like her; but had another scent to it she was not unfamiliar with. She knew the smell... then she remembered where she had smelled it before; during her springtime visits with Celestia!

After a little more “experimenting” with her outer vagina, she read more from the book; “The vagina, which can expand from five inches to as long as almost eight inches; is highly flexible, allowing for it to be stretched to even greater lengths. Above the vagina is the ‘cervix’, leading to the ‘uterus’. Branching off from the uterus are 2 ‘fallopian tubes’; which in turn lead in turn to the ‘ovaries’, which produce an ‘egg’, the female reproductive cell, once per heat cycle.” Twilight used the slippery substance to coat her entire vagina, the pleasure caused by the process causing her to bite her lower lip almost hard enough to draw blood. She then plunged her hoof a little deeper, but sharply pulled it out as she pushed against a barrier and felt a stinging sensation. Once again referencing her resource, Twilight read “…In virgin mares and fillies, a band of flesh, called a ‘hymen’, may be present, and will cause pain upon breakage.” Twilight decided to avoid pressing deeper, and instead chose to explore a little lower.

Once again eyeing the book, Twilight read: “…Below the vaginal entrance, at the base of the labia major, is the ‘clitoral hood’, which covers the ‘clitoris’.” Looking once again at the mirror, Twilight quickly discovered her clitoral hood and, upon moving it with a gasp, her clitoris. When she touched this small nub, her haunches immediately bucked into her hoof, causing a wave of intense pleasure to flow through Twilight, and baffling the young alicorn in the process. Having explored all shown by the diagram on herself that she dared, she decided to move onto the next page, which contained the diagram of a stallion’s anatomy.

~ ~ ~

Twilight had seen a stallion’s sheath and sack many, many times before; but never really as up close or in as much detail as the diagram showed. “Inside the sheath, or ‘prepuce’, is the ‘penis’; whose main components are: the head, or 'glans', the shaft, or 'body', and in the center of the body the 'medial ring', which serves to provide additional sexual stimulation during intercourse.” Twilight said, while feeling a significant increase in the burning sensation from her haunches. “Beneath the penis are two ‘testicles’, contained within the ‘scrotum’. The testicles produce ‘sperm’, the male reproductive cell; and there are also a number of accessory glands, producing ‘semen’, which carries the sperm into the female’s reproductive tract in a process called ‘breeding’”

Twilight cocked her head. “But how do the sperm and semen get into the vagina? What is ‘breeding’?” Twilight asked herself, turning the page. Reaching the next page, Twilight read;

“Breeding occurs during the ‘heat’, or ‘estrus cycle’, of a mare; a time when a mature mare's body ovulates and releases an egg, generally in-between early spring and summer. Exactly when depends entirely on the individual mare, but is generally within early-to-mid spring. During the ‘heat’; a mare will feel a warm to hot, itchy sensation of varying intensities in their reproductive tract, and their labia major will inflame and excrete a clear, viscous fluid to both instigate and facilitate mating; as it  both contains hormones to attract a stallion and is viscous enough to make breeding easier.” Twilight perked up a bit, her eyes glittering at the realization; “So that’s what this burning sensation and leaking is; it’s my body telling me I’m ready to breed!”

Twilight’s enthusiasm was then a bit dampened when she realized she didn't even know what that meant. She turned the page to see a diagram of a penis inside a vagina, and on the page opposite it a diagram of ejaculation. Flushed by the explicitness, Twilight started reading;“When a stallion senses a mare in heat; he will nip at her rear, and she will urinate and ‘wink’, contracting her vaginal muscles in a specific way, to show her readiness to breed.” Twilight’s nose scrunched a bit at that part, and then she continued reading.

“The stallion’s penis will erect, expanding three to four times in size and getting rigid. This will enable the stallion to penetrate the mare’s vagina. After erecting, the stallion and mare may engage in 'foreplay', stimulating each others genitals in order to further sensitize and prepare themselves for breeding.

After 'foreplay', the stallion will mount; or climb on top in a specific way (a diagram is shown of a stallion mounting a mare), the mare, and will penetrate the mare’s vagina by thrusting his pelvis in such a way as to cause his penis to enter her vagina. If the mare was a virgin, the hymen will tear upon penetration, causing pain and minor bleeding to occur. After the mare recovers, she will generally create more of the lubricant to ease the friction between the penis and vagina, and the stallion will also sometimes produce viscous fluids of his own to facilitate the breeding. The stallion will then proceed to repeatedly thrust his pelvis, engaging in 'intercourse', causing his penis to move into and out of the mare’s vagina until enough stimulation is accomplished to achieve an ‘orgasm’.

During an 'orgasm', extreme pleasure is felt by both and a series of involuntary bodily functions occur; for the stallion, orgasm will result in the penis’ head, or ‘glans’, ‘flaring’ and ‘ejaculation’, or forcing out, of semen; which generally contains upwards of four billion sperm, from the penis into the mare’s vagina. ‘Flaring’ of the penis involves it expanding in diameter to prevent semen from leaking out and to press the ejaculate deeper into the mare’s tract with further thrusts.  For the mare; orgasm will cause her vaginal muscles to contract and relax rhythmically, further stimulating and encouraging the stallion to ejaculate more, and drawing the ejaculate deeper into her vagina, making possible 'fertilization', or joining, of the egg with the sperm more likely. These actions will generally create a foal, barring any possible complications…”

The text went on to describe possible reproductive complications; specifics on sex cell fusion and multiplication, and to describe and diagram gestation and birthing, as well as lactation and foal-care suggestions, all of which Twilight read with either great interest or disgust.

~ ~ ~

After re-reading the section of text describing breeding, and studying the diagrams further; and without her even realizing it, Twilight’s hooves had started to rub her now soaked and burning sex. Setting the book down, she now focused more on the sensations she was getting from her nether. Twilight looked at the mirror, watching her hoof rub her genitals, this turning her on even more. With every rub, she would increase the force and speed, but never the depth, of her efforts. After a few minutes of hoof-placement variation, she felt everything coming to a head as her sex was clenching on her hoof now. Twilight suddenly gasped, and arched her hips up into her hoof, experiencing her very first orgasm. Wave after wave of pleasure wracked through Twilight’s body, her body milking and grinding against her hoof; all the while Twilight was barely able to breathe from the sensations. “Wow,” Twilight said, her head still swimming from her orgasm, “that was amazing; why have I never tried this before?!”

Twilight’s sex still burned, so she picked up and opened the book to see if there was a way to stop her ‘estrus cycle’. Reading a section she'd previously missed, Twilight read aloud; “A mare’s heat will generally end naturally after a period of about two to three weeks without breeding, or after a successful breeding session resulting in a stallion ejaculating inside her. If impregnation is not accomplished, the mare will go into heat again at a later time. There are, however, also other ways to artificially end a mare’s heat; including spells and potions.”  Twilight turned the page again, and noticed a sealed note dropped from inside the book. Picking it up off the floor, Twilight broke the seal, and read the note aloud:

My dearest student Twilight,

If you’re reading this, it means I believe you have grown and learned enough about friendship, and have entrusted you with learning about reproduction; which may lead on to something even deeper then friendship: love. Due to your curiosity and knowing your habits; if you’re reading this note when I expect you are, during your estrus, I have a task for you. You are to travel immediately to Zecora’s hut and ask her to prepare a ‘Heat Potion’ for you. This will end your heat, and thereby any discomfort you may be feeling…unless of course you have a special somepony you want to share it with…

Forever your mentor,

Celestia

Twilight giggled at the last sentence, figuring it was just Celestia pulling another prank on her; Twilight knew that Celestia knew she wasn't romantically interested in anyone. Never one to reject the Sun Princess’s requests, even if it meant putting herself in danger at midnight, Twilight immediately packed her saddlebags with a few essentials; including the book on reproduction, another book involving basic unicorn spells (so she could ask Zecora if any would help with her condition), the note, and a couple carrots and bottles of water just in case, and headed off to the Everfree Forest.

Unbeknownst to Twilight, had she read the last page the letter was covering, she would have discovered the spell to end her heat.
