Some Combustible Lemons

It was the stars that brought you here.

Since Luna's return, the night skies had changed beyond all recognition, and the job had fallen to you to re-write the official Royal Calendar. It was a simple task, well within your abilities – but you needed information about both the old and the new movements of the heavens and time to compile them into a consistent and rational system to measure the seasons and account for the passage of years.

Unfortunately, the Royal Library no longer had the standard ephemerides used to schedule stellar events. All of them were out on inter-library loan to a provincial library out in Ponyville.

The librarian there was a personal pupil of Celestia herself, and the author of several exceptionally impenetrable tomes on ancient history and the development of magic. You dreaded the idea of meeting her in person – she was, by all accounts, a loner interested only in her studies, cold and arrogant. You imagined her as some dusty, wrinkled old prune from the formal tone of her writing.

Your arrival in Ponyville was disorienting. Compared to the graceful spires and measured avenues of Canterlot, the chaotic mixture of architectural styles and bizarre road layout left you hopelessly lost.

Fortunately, a friendly purple unicorn came to your aid, a pretty young mare carrying saddle-bags filled with books. You wondered if she was a school teacher – she was very familiar with the way to the town library. She was also exceptionally patient, showing some small spark of interest as you described your business in town and digressed into some of the details of calendar-making. It was easy to imagine her herding a room-full of unruly colts and fillies.

She walked into the library – it was built into a tree? – as if she owned the place, set down her saddle-bags, and twirled around gracefully.

With a sweet smile, she introduced herself. “My name's Twilight Sparkle. I'm the town librarian.”

You thanked the stars above that you had said nothing about your misgivings.

Her assistant, a green and purple infant dragon, scurried to locate your books. She called to him, "Spike! Set our guest up in the back room -- he's going to need some peace and quiet!"

The next few days were eventful. You had work to do, and the time and peace and quiet to get it done. Columns of numbers, the rising and setting times of sun and moon and stars and planets, measured the long slow rhythm of the year. The occasional distractions were welcome, although Twilight Sparkle always made a point of apologizing profusely for interrupting your work.

Twilight Sparkle had an entertaining and diverse collection of friends, who would often come to visit. She did an admirable job of looking after them, listening to their problems, and trying her best to help. Sometimes you would peek over the top of your book to watch her and her friends talk. It made you happy to see that she had a good life in Ponyville.

You noticed something else as well. She was very pretty.

One day, her hyperactive pink friend came by, looking for new cake recipes. It amazed you to see just how patient Twilight was, slowly helping her bouncing friend to figure out the right kind of cake for the occasion, and you spent a few minutes just watching the two talk.

Suddenly, the pink pony shot you a quick look, smiled slyly, and whispered something in Twilight's ear.

Twilight looked shocked. “Pinkie!”

She then whispered something into Pinkie's ear that made her friend giggle uncontrollably. As her friend rolled on the floor laughing, she gave you a quick look and a devilish smile.

In the following days, Twilight made a point of bringing you fresh tea and chatting with you. The first few times, Spike would tag along, but she shooed him away.

She was interested in your work. One afternoon, she spent a few hours with you, helping you revise your figures with a pair of reading glasses perched on her nose. Organized, methodical, and with a fantastic attention to detail, she was fascinating to watch.

She caught you staring at her, and smiled back, putting you immediately at ease.

The next afternoon, she came into the back room where you were working and began shelving some newly arrived books. She took her time, and you watched her work. Her tail swished back and forth as she levitated one book after another onto the shelves.

You blushed when she noticed you looking. She giggled sweetly, and you did as well.

You looked back down at your papers, and started as she came to your desk. You looked up and she kissed you, full on the lips, and whispered in your ear, “It's all right.”

Later that evening, as the library was about to close, you gathered up your papers.

“You don't have to go.” She smiled again, and winked at you, whispered in your ear, “Let me lock up and take care of some business.”

You trembled a little. She smelled of lavender and her violet eyes were sparkling.

She returned, wheeling in a cart of returned books. She gave you a grin and turned around to return them to their shelves.

You were startled when she let a book fall. She bent her front legs and lowered her head to the floor.

The Princess' prize pupil provocatively poised her pleasantly pert purple posterior.

You finally noticed you had an erection.

Her tail flipped up, and she turned her head to look at you slyly. Her horn glowed, and you felt a purple warmth grab your member.

“Gotcha.”

You came to her, and you kissed. She slipped her tongue inside your mouth.

You no longer felt her telekinetic grip, but her horn pulsated. She had told you she loved to roll in wild lavender; her smell was intoxicating.

Your necks briefly intertwined, and you were on top of her before you are even aware of what you were doing.

Her horn glowed, and she gently squeezed your throbbing erection. She threw her head back, eyes closed, grinning like a maniac.

You wanted to be gentle and enter her slowly, but she was hungry. Her opening gripped a little and relaxed, and you slid deep inside her.

She was warm and wet, relaxed and eager for you.

You were fairly certain you now knew what she had been doing with her horn.

You both fell into a slow, pleasant rhythm as she bucked gently beneath you, keeping you deep inside her. Sweat and musk joined lavender. Her back felt warm when she pressed against you.

Time stood still, and the frequency of her breathing and the pace of her rhythm against you picked up. Her horn sparked in a faster harmonic of your fucking, and her ears flip back.

You gave her ears a gentle nibble as she began to orgasm, crying out. She bucked you harder and harder as it took her. Her pussy tightened on you as she came to a climax.

Her pressure ironically made your erection die down a little. She smiled wickedly.

“Oh, not yet.”

Her horn glowed, and you felt a ring of pressure around the base of your cock. You felt yourself get rock hard inside her firm warm wet grip.

“So... horrnnny...”

She stretched the world out into two distinct syllables, and gave you another maniacal grin.

The bucking resumed. She was rougher and faster this time, and her magical grip was still locked around the base of your cock. Sweat, hers and yours, and musk filled the air.

You thought you'd orgasm, but her grip held you back. She wanted more, and you were pleased to give it to her.

The muscles at the base of your cock spasmed pleasantly. You've never experienced anything like this before, never been this hard. Her walls increased the pressure again, and the pace quickened.

She lost her grip as the second orgasm came. You thrust as deeply inside her as she cried out, and moaned when the muscles finally released your load deep inside her, spasming, and again, and a third time, pumping your seed deep inside her.

You both took a moment to catch your breath. You were still hard, but flagging rapidly. Her mane was wet with sweat.

She kissed you, and your tongues rubbed against each other passionately. You were still inside her, and could feel your semen ooze out of her and drip down your balls.

She smiled beneath her sweaty bangs, and her eyes shone like stars.

“I think I'm gonna need a nap.”
