Dear Twilight,

I tried to wake you up but you wouldn’t budge. I promised Apple Bloom I would help her wash their hog Petunia for the county fair tomorrow. She said that Sweetie Belle would be coming over too and that Rarity would probably stop by. Not that I care, just sayin…

Not sure when I’ll be back, but I’ll see you later.

Love,

Spike

P.S. You might want to take a bath. You smell kind of, uh, funky.

Twilight lay on her side reading the note. When she was done she moaned and rolled back over on her face.

She felt awful. She hadn’t gotten up and cleaned up after she came, she just slept. Her sleep was full of perverted thoughts of Applejack. She’d woken up, pressing herself against her foreleg, She’d ended up by raising her haunches up, resting on her knees, covers off and with her thighs spread wide apart, she leaned forward and reached back between her legs to massaging her lips and clitoris with her hoof. She'd rubbed furiously, finally bringing herself to an abrupt and powerful orgasm while biting down hard on the pillow to keep from crying out. She’d collapsed afterward and dragged the covers over herself.

Now it was morning and she lay there exhausted and feeling like a perverted wretch, with her coat all around her stomach, inside her thighs, along the lower part of her foreleg, all crusty and sticky. There was still wetness between her legs and the sheets were soaked with her thick wetness and her perspiration. Funky? She stunk!

She was full of self loathing. She was a filly-fooler, and a sick disgusting lowly wretch who did horrible things to herself while having the most perverted dreams about a mare. Who she decided that she was in love with...

She wanted to die.

What is it that could make be behave so disgustingly? I don’t understand! I’m a good pony, at least I used to be. Now I’m just a pervert. How will I ever face the Princess again?

It was that thought that sent her over the edge. She burst into tears and buried her face into the pillow, crying miserably. Finally she turned over, sat up and sighed.

Then a thought occurred to her.

“I wonder if I’ll be able to...”

The perimeter of her closet door began to glow and the door opened. The sound of shuffling came from the closet and then out floated a small chest. It was of solid oak construction and it bore the personal seal of Princess Celestia...

Quite some time before Twilight left for Ponyville, the princess had tried gently broaching the topic of equine reproduction to her young charge. Twilight's reaction had been one of great discomfort. The princess realized that she had forgotten that although Twilight was quite advanced in her prodigious magic abilities, emotionally she was still quite young.

As she considered the situation, Princess Celestia decided to meet with Twilight Velvet and Night Light, Twilight’s parents. They discussed the topic and agreed that Twilight should be given more time before the subject would be broached again.

That had been a year and a half ago, and now the three of them agreed that it was time. They also agreed that rather than have to discuss such a personal topic with another pony, Twilight would most likely prefer to study the subject on her own and come to them with questions, if she needed to. Celestia and Twilight’s Mom discussed what books they thought would be most beneficial. Night Light excused himself with an embarrassed smile and went to meet his son Shining Armor.

In the end they selected 5 books for Twilight, The first was a dry clinical medical textbook, the second a book on equine sexuality, third a book devoted to mares and the unique natures of their bodies, -a sort of “care and feeding” book that included personal stories from mares about their journeys of self discovery as pertaining to their bodies..

The last two books were romantic novels that involved sex. The first was somewhat tame and while employing a fair number of euphemisms, left no doubt as to what was going on. The other was a lusty, fully adult novel with explicit sex scenes. Just as they were settling on the last book Night Light and Shining Armor came through the door.

They bowed to the Princess. “Good afternoon your highness.”

“Hello gentlecolts. Shining Armor, I’m so glad you came by. Look who’s here.”

“Mom!” he said, going to her with a hug and a kiss to her cheek. “So what are you two up to?”

“Well,” the Princess replied. “we’ve been selecting books for your sister to read. We feel it’s time for Twilight started to learn about all things sexual.”

Shining Armor stood there frozen. The sadness in his eyes made his Mom put her hoof over her heart. “Oh, honey…”

“Twily? M-my little Twily?” he said in a tiny voice. “But she’s only…” He looked utterly lost.

“Seventeen, honey,” his mom said.

He turned to his father. “Dad…? That can’t be right. Seventeen?”

“I’m afraid so. She’s growing up son. I know. The years pass so quickly.”

Shining Armor hung his head and shook it slowly. “I-I can’t believe it.”

“How is your new friend Princess Cadenza?” The Princess asked, changing the topic to something happier.

“Cadence?!” both parents said aloud simultaneously. “Twilight’s old foal sitter?” Twilight Velvet said, “The one you used to tease all the time?”

Shining Armor blushed. “Yeah, well we’ve kind of become friends.” he looked up at the Princess who gave him a quick wink which made him blush all over again. He wiped a stray tear from the corner of his eye.

“You know Shining, I think you might take your parents to see her. It would do you some good too. I know you’ll find a very sympathetic shoulder there. She loves your sister as much as anypony I know.” Celestia said with a smile.

Shining Armor nodded again, but the look of sadness wouldn't leave his eyes. He turned to his mom.

“How about it? Would you and Dad like to go see her?”

“Of course we would! We love her!”

“Well okay then. Let’s go.” Shining said, and headed for the door.

Both parents looked at the princess with the same question on their face.

The Princess smiled happily and gave a little nod. The parents beamed at each other and did a hoof bump.

The day before her departure for Ponyville, the Princess had summoned Twilight to the castle’s large balcony overlooking Canterlot.

“Hello Twilight.”

“Hello your highness.” The young mare said, bowing.

“So tomorrow is the big day. Are you excited”

“Well, yes, kind of. I just wish you’d let me stay here and do more research about Nightmare Moon. My research confirms that on the one-thousandth Summer Sun Celebration, she’ll return!”

A fleeting look of worry passed over the Princess's face. Then she brightened. “Yes, I know, and I did read what you’d sent me. I’ve got most of Canterlot’s top historic scholars researching this.”

“Most of? Why not all of? The celebration is tomorrow night!” Twilight exclaimed worriedly.

“Because one of our best is leaving for Ponyville tomorrow morning.” Celestia said, and ran her hoof lovingly over Twilight’s jawline before cupping her chin and lifting it. Twilight blushed, but the worry didn’t leave her eyes.

“I really think I can be of better use here, with the scholars doing research.”

“I know you do sweetie, but you have a role to play in Ponyville, and you need to make friends.”

“But-”

“Eh! That’s enough Little Light. I understand your concern, and I promise you that in the next few days I’ll be in touch and we’ll have lot’s to talk about.” Celestia had used one of her pet names for Twilight as a way to let her know that the topic was closed. “Now, my beloved student, I have something for you to take with you.”

“Really?! What?” Twilight brightened. “A book?”

“No…”

Twilight frowned.

“Five books.”

Twilight’s smile returned in force and she started bouncing joyfully around in a circle. “Yes! Yes! Yes! Are they about The Mare In the Moon? Or Nightmare Moon?” she asked excitedly.

“Not exactly…” Celestia answered with a raised eyebrow.

Twilight stopped jumping and regarded her mentor quizzically. Then she squinted. “They’re not about…”

Celestia raised the other eyebrow to match the first one. Twilight's shoulders slumped. “...that...are they?” But the question was pointless. She knew the answer - of course they were. “Do I have to write a report?” she cringed.

“No Twilight, you do not.”

The young unicorn breathed a huge sigh of relief.

“In fact the books are in a chest that is locked with a spell.”

“To keep Spike from opening it?”

“Him and you.”

“Me? I thought you wanted me to read them.”

“When you’re ready”

“How will I know when it’s time to open it? Is there a book I can read that will tell me? Should I send a note to you and ask you? Will you send…”

“Don’t worry,” the Princess interrupted, “You’ll know.”

“But-?”

“When the time comes, just use our private unlock spell, the one that only the two of us know. Feel free to try to open it any time, but only when you’re ready, will it unlock…”

“Where is it?”

“Just over here.” Celestia led Twilight inside and over to her throne. There was a wooden chest with small iron bands around it. There was no sign of a lock anywhere but Twilight knew that it meant nothing. Celestia’s magic was unbreakable. “Go ahead, try” The princess said with a smile.

Twilight’s magic aura surrounded the box and Twilight applied the spell. Nothing. She tried a different spell,

“Sweetie, the first spell was the right one, but you’re just not ready yet.”

“Not ready yet! I’m one of the youngest graduates of the top level spell casting class! What else do I need to know to open this? It’s a simple spell!”

“Well, yes, that is true, but there is a little twist to it.”

“It will only open when I’m ready.” Twilight groused. “I get it.”

Celestia smiled at Twilight's scowl. “That’s right, I knew you’d catch on.”

“Well I’ve decided that I want to read them now.”

“Oh good!” the Princess said, “Try again.”

She did, but no matter how hard she strained, the box would not open. She spoke through gritted teeth as she continued to struggle with the box’s magic.

“Why won’t you open?!!

“Because you don’t want to read the books, Twilight, you just want to open the box.”

Twilight released the box from her spell and sat there panting and sweating.

“But I do! I want to learn about it!”

“About what?” the Princess asked innocently smiling.

“You know, about...that.”

“You’re unable to even say the word. Do you really think you’re ready?” Celestia asked.

“Sex.” Twilight blurted out then furiously attacked the box with her magic again. She was having no more success than she’d had earlier, but she kept at it.

“I’m afraid I have to go now sweetie, Celestia said, “You may continue to try if you wish. Don’t forget your parents will be here for your farewell dinner tonight. We’ll be in my private dining hall as you requested. See you at 7.”

Twilight, exhausted, suddenly collapsed, spread-eagled on the floor. She lay there panting hard and sweating.

“You might consider a shower before then.”

Twilight just looked up at her and scowled.

Now she looked at the chest in front of her, sitting on the bed. Tears still fell from her eyes. She wiped her nose with the back of her hoof.

She knew it would open. It did.

Inside she found a packet of tissues, a hand mirror, the five books and three envelopes numbered 1, 2 and 3.

She opened the one marked 1.

"My dearest Twilight-

It’s okay, it’s okay, calm down sweetie and stop crying. Take some tissues from the packet, wipe your eyes and blow your nose. Once you are calm and relaxed, you may open the second envelope."

Twilight was utterly dumbstruck.

How did she know?!! she wondered.

After several deep breaths, Twilight found herself a little more relaxed. She opened the second envelope.

Feeling better sweetheart? Good. Now take a few more of the tissues and wipe yourself between your legs.

Twilight lay back and pulled the blanket up to her neck. She looked around the room fearfully.

“Puh-P-Puhrincess?” she called out. “I-I got your letters…” She pulled the blanket up to her eyes.

No sound.

She relaxed slightly and slowly lowered the blanket. She picked up the note and read more.

Have you finished cleaning up? Go ahead, you’ll feel better. When you’re done, you may wish to use an incineration spell to dispose of the tissues. They tend to be somewhat musky.

Twilight took several tissues and dutifully wiped between her legs. It took several tissues and several wipes, but eventually she felt cleaner and better. She read on.

I think I owe you an explanation-

I know you’re wondering about the spell-

There was no spell beyond our private lock spell. The reason you couldn’t open it, was because deep down you really didn’t want to. But now one of two things has happened that has made you able to open it up. An unlikely thing and a likely thing.

The unlikely thing is that you felt a great desire to understand certain feelings you were having. While in the past, that has applied to everything you’ve studied, the energy you’ve devoted to avoiding this topic is what suggests that this method is unlikely.

The likely thing is that the desire finally hit you, and when it did, for one of the first times in your life, you acted before you read…”

The writing stopped. Then Twilight noticed it continued at the bottom of the page

How did you like your first orgasm?

Now Twilight really freaked. Her face went pale, she dropped the note and pulled the blankets up around her body. She looked around the room frantically. Still nothing She turned the note over to read the rest, There was one work on the back.

Gotcha!

Though still somewhat uncertain, Twilight had to laugh. It was one of Celestia’s favorite words. It told her that everything was okay. She opened the envelope marked 3.

So sweetheart - Congratulations! Aren’t orgasms wonderful?

I’m well aware that I still owe you more of an explanation.

Twilight, my most loyal and beloved student, I know that most likely you are sitting in bed on wet sheets and feeling wretched. (though less so, I hope) You see you have spent a great deal of time reading about life rather than living it. You are at a stage in your life where your body is going through many changes. You have ignored them in the interests of your studies.
I tried to talk about this with you when you started having your estrus cycles, but you told me in no uncertain terms that you did not wish to discuss the matter. I knew that one day the time would come when your body would wish in no uncertain terms, to have that discussion with you. And it would do all the talking.

As I wrote earlier, you could have opened the chest if you desired to learn why your body was making you feel so, aroused. But I know you and when it came time for your body to have that conversation it would be somewhat overwhelming. It might have been caused by one of the books in the back shelves of the library that a certain Princess might have left there for you, or perhaps by some handsome young colt that caught your eye and you found yourself fantasizing about him.
Your body has been waiting for this, so don’t be surprised if you felt a little out of control. I’ll bet you passed out afterwards and slept through till morning and woke up feeling guilty and wretched.
What you need to understand is that what you did was a wonderful part of life. It’s completely normal and feels great. Feel better sweetheart? No I didn't think so. But after you think about it and given it some time, you will.
Onto the books-

There are five books in here, each numbered. It’s not necessary to read them in numerical order, however if you start with the 5th book, you may come away both shocked and somewhat intimidated.

The book labelled 1 is clinical and may make you feel more comfortable. It covers the physical parts of your reproductive system. It’s important to know some ot what is in here, but not absolutely necessary for enjoyment.

The second book is less about how to make foals and more about the other part - the pleasurable part. It discusses social attitudes, behaviour, practices, and the role that sex plays in our lives.

The third book is for mares. It talks about our sexuality, about challenges that are unique to our sex, about personal experiences, about taboo subjects, about repression and abnormalities both moderate and extreme - like waking up in the middle of the night to masturbate!

(Gotcha!)

Twilight laughed. The fact that the Princess knew that she had masturbated. Before she had even done it… It was confusing yet despite her confusion, Twilight could not stop blushing.

Seriously though, there are some ponies with such strong libido’s that this actually happens. I can see your red face even from back here in the past! I apologize but I must confess - this is great fun! Making you blush from this far away! But isn’t it funny? You see my dearest Twilight, that is sex. It’s funny and fun and wonderful. It’s pleasurable and it makes little foals. What could be better? Enjoy it!

Somehow I know that it will take you awhile to come to terms with it, and that is fine. It is something that connects every living being, is necessary for life to go on, yet nopony talks about it. I must tell you it is very difficult for me to refrain from reaching through time and space and making you blush.

Sweetie, you are not the same pony that left Canterlot, though I suspect it wasn’t that long ago. There is a physical part to friendship, whether it’s the comforting touch of a friend that can say more than any words ever could, or a kiss from someone you love. As you make friends, you will discover this. Many times friendship grows into love, and that comforting touch becomes a caress, and that caress leads to making love.

That is really why you’re there, to learn about love in all its wonderful aspects. Friendship is a very special kind of love and where it can lead is a journey we must all take if we want to really live. It’s what our history is - not wars and conquerors, not nations and rulers. All of history is families, it’s friends, it’s love.

So my young mare, go out and live, make history, and have lots of wonderful orgasms!

(Gotcha again!!)

Oh - the last two books. The fourth one is mildly erotic. The fifth one is, well, far more so. You will find them both quite inspirational.

(I always have.)

(Gotcha yet again! I must apologize, but I truly wish you could hear how hard I am laughing!)

With all my love forever-

C-

Oh one more thing - the only other thing that would have driven you to the point of finally overcoming your inhibitions and masturbating, is that you fell utterly and totally in love, but if that were the case, then you probably woke up and did it again!

Gotcha!

Author's Note

Okay, okay, so I was wrong about the hiatus. I was scanning through my tales and re-read this one and I liked it more than I remembered. So I added another chapter. I have enough for a third chapter as well...
