The Secret

Spike felt a cold sweat forming at the base of his neck as  he looked down at his empty claw, unsure of what just happened.

“D-did I just?”  He took in a shaky breath, unable to finish the sentence.  “Twilight is sooo going to kill me.”

In the midst of reorganizing the castle’s library, Spike had stumbled across an old copy of The Invisible Mare.  It took him only a second to realize that this was Princess Celestia’s personal copy, and it took him another second to realize what was on it.  When he finally did, however, he’d dropped the book and let out a yelp of surprise, accidentally triggering his flame breath and sending the book en route to the Princess herself.

“This is not good,” Spike decided, fear beginning to take over. Shaking a bit, he glanced up toward the huge crystal staircase that led to Twilight’s room.  She’s going to be so mad…

Spike then forced himself to take a deep breath. Maybe it’ll be all right though, maybe I didn’t actually send the book to Princess Celestia.  Maybe it was just incinerated. Better than Celestia finding out, after all… I think.

The lump in his throat said otherwise. Spike knew his own breath well enough to be one hundred percent sure that a filthy book just landed in Princess Celestia’s room.

Looking back at his empty claw once more, Spike sighed and clenched it shut. He felt a fleeting sense of panic at the realization that both Twilight and Celestia might become immensely angry with him, but it didn’t last. The deed was done, and there really wasn’t much he could do at this point, except maybe pack up and try to hop the border to Mexicolt.

Actually, that’s not a bad idea.  If I hurry, I can get all my Power Ponies comics in order, and--

Just then, a rapid, angry knocking sound came at the door, pulling him out of his thoughts as all of his muscles grew tense.

TWILIGHT SPARKLE!

Spike then turned around to the front door, a sickening feeling welling up in his stomach.  He had a very good idea of who that might be, the cold sweat on his back suddenly feeling like a waterfall.  Without many options, he slowly, and reluctantly, walked over to open the door.

Before he could, however, the entire frame was blasted open by a powerful magical beam, shards of what was once their crystal door flying everywhere. Spike threw up his claws to shield his eyes in response, crouching a bit. When it was safe to open them again, he peeked through his digits.

Princess Celestia stood, seething, it what remained of the doorway.  Her face was beet red with untold rage, and her mane whipped behind her in a cross manner.  As the Princess inhaled, Spike could tell she was pissed -- though his first clue was the demolished door.  Celestia fiercely stomped into the library, and he backpedaled as a result.

“P-Princess Celestia!” Spike sputtered.  “H-hello. What brings you here?”

Every muscle in Celestia seemed to tense up at once. Then she relaxed slightly, and in a very calm tone spoke with her usual clarity and regality, she said, “I need to speak with my former student.”  With a glance back at the shattered debris behind her she added, “And, I apologize for the door.  My temper was not in check… In fact, I believe as soon as I see Twilight, it shall return tenfold.  Where is she, by the way?”

“Uh… I think she’s up in her room right now.”  Spike gestured up the nearest stairwell.  He got an uncomfortable feeling in the pit of his stomach for ratting her out so quickly, but he knew that if he lied, then he’d be feeling uncomfortable in many other places as a result.  Princess Celestia promptly brushed past him and made her way to the stairs.  With each step she began scowling again as her anger returned in full force.  “Er, wait! I don’t think she wants anypony to interrupt her!”

It was too late, Princess Celestia flew to the top of the stairs, completely ignoring him.


“Gah, why do I keep doing it on the books!?” Twilight grunted as she finished her private “studying” session, the last few waves of pleasure fading away as she collapsed onto her side panting. Who knew satisfying one’s needs could be so exhausting? Energy slowly returning, she turned her head a bit and glanced over to the book that had been previously underneath her, smothered with white.

Ugh, why do I keep doing this?

Muttering a few curse words under her breath, she cast a quick spell, setting “A Horse Hiker’s Guide to the Galaxy” down at the bottom of her bed. Twilight then reluctantly leaned up as she realized that she’d left Spike alone for a bit too long, hopping down to the floor.

Dear Luna, hope he hasn’t done anything stupid to the library Or noticed any of my... Shaking the thought out of her head, she proceeded to give her wings a good few flaps before tucking them into her side, along with stretching out her limbs a bit.

Once she felt that all the soreness from her body had been eradicated to the best of her abilities, she walked off to her bedroom door, mumbling,“Alright, now I just need to-”

“TWILIGHT SPARKLE!”

Every muscle in her body froze as the unmistakable voice echoed through her castle’s marble halls. Slowly craning her head back to the book covered in her juices, Twilight felt her stomach, along with most of her body, begin to fill with nervousness. Then she heard the explosion.

Oh no…

Adrenaline racing through her body, Twilight broke into a gallop back towards her bed, staring at the book laying upon it in horror. Tapping her hooves nervously, she quickly put all of her focus on her horn, only to be distracted by the sound of somepony approaching her door.

Clop clop clop clop clop.

She let out a fear-induced squeak, frantically raising a hoof and smearing it all over the cover in hope that she could get some of her fluids off. But when Twilight saw that all she was doing was hopelessly spreading the creamy-white liquid, she found herself shaking all over as her movements grew more desperate.

Ew, ew, ew, c’mon Twilight!

“YOU DENSE LITTLE FOAL!” a voice screamed, the sound of her door being slammed open following.

Letting out a shocked yelp, Twilight tried to turn around, only to slip on some of her excess mare seed. Fore hooves still pressed against the book, she found herself being slammed against the floor as she lost footing, the book falling with her…

...right onto her private area.

“TWILIGHT, YOU- oh damn…”

There was Twilight sitting before her, right on her back with a cum covered book pressed against her marehood. She was also bright red and panting, her hooves just as covered as the novel her thighs squeezed against.

“Am… am I interrupting something?” Celestia asked a bit shakily, her anger switching to discomfort. She attempted to peel her eyes away from the sight before her, only to find that she couldn’t.

“I… uh… well…”  Twilight stammered, her blush widening to encompass her whole face.  Realizing that she was still lying in her own fluids, she attempted to stand up.  It was a task easier said than done, as she found her hooves slipping on the near frictionless floor.

Finally, she managed to stand upright on all four hooves. Celestia still wore a look of uncomfortableness,  her pupils tiny and staring at one spot in particular.  Twilight followed their line of sight, and saw that the spine of the book was still wedged in her marehood.

Igniting her horn, she wiggled it free -- unable to suppress a moan as she did so -- and tossed it aside.

“P-Princess Celestia!” Twilight struggled to get her bearings.  Her face was still hot and sweaty, and her heart threatened to break at any moment. Acting nonchalant was out of the question, so Twilight sighed.

“I… I’m sorry you had to see that…”

“I did a lot more than see it,” Celestia murmured to herself.

“What?”

“Nothing.”

Celestia then blinked, suddenly recalling her rage from earlier. She looked down at her fellow princess, who was shamefully bowing her head to the ground.  Noting that Twilight was far more uncomfortable than she, Celestia couldn’t help but break out into a smug grin. Piecing the bits of information she had, she spoke.

“Ahem.  Twilight… you have a book fetish… don’t you?”

Twilight’s whole face turned crimson.

“Psh, wha… whaaaat? Me, have abook fetish? Why, I never!”

Celestia’s grin only grew wider.

“Then tell me, Twilight, what would you do if I said… hmm, I don’t know, that having a book fetish is weird?”

That was the straw that broke the camel’s back, and Twilight spoke with anger.

“DO NOT DARE TO INSULT THE BOOKS! THEY ARE SACRED! SACRED!”

Twilight’s wings flared out in rage with the words, her features compressing into pure rage.  Celestia might have found the display threatening, if not for the copious amount of white juices coating the young alicorn.

Twilight then proceeded to levitate the book back into her arms, silently whispering,”Ignore the nonbeliever, ignooore…” as she caressed it softly with her fore hooves.

Her grin wide as it could ever be, Celestia interrupted.

“Ahem…”

Twilight then froze up once more as she realized what she’d been doing. Tossing the book away for the second time, she put on her best poker face as she straightened her posture and cleared her throat.

“I just, er, really like my books…”

Celestia raised an eyebrow.

Twilight sighed.

“Or I have a book fetish…”

“I figured.”  Celestia surveyed the room they were currently in. An abundant amount of the unmentionable liquid covered the bed and floor, and looking down, she could see that she was even standing in some. Shuddering, she backed up.  “It’s more or less the reason that I came here today.”

Twilight blinked, a look of surprise taking over her face.

“Y-you knew?”

“No.  But certain suspicions arose when Spike sent me back my copy of The Invisible Mare that had a not-so-invisible substance coating the cover.”

“Spike sent that?!” Twilight exclaimed, eyes widening.  “He saw that?!”  Hyperventilation set it.  Twilight began applying a breathing technique that Cadance must have taught her, but it did not appear to be working.  She sucked in and spat out air at such an alarming rate that Celestia felt genuine concern that she might pass out.

“Relax.  It did not appear he knew what it was.  In fact, I believe he must have sent it to me by accident.  However, this does not really change the facts.”  Celestia now bore a look of disappointment, her jaw became firmer, her eyebrows lowered, and her eyes were hard and angry.  “Twilight Sparkle, you fornicated with my favorite novel.”

“...I know,” Twilight meekly replied.

“And I tas... Never mind.  I just want to know why?  You must have hundreds, if not thousands of books here, so why… ahem, jack off, to mine?”

Twilight’s crimson face quickly became an even deeper shade.  “Well…. it uh…”  She trailed off, mumbling.

“What?”

“It… It smelled like you, all right?”

Celestia’s eyes widened.  This new revelation caused her to take a step back in shock.  “It… smelled like me?”

“Yes...”

“And because it smelled like me you felt compelled to rub it against your marehood?”

“Yes…”

Celestia was speechless.  At this point, she wasn’t sure whether or not she should be angry or surprised.

“Well, er, that’s… that’s just a little bit weird, Twilight. I mean, I was your teacher since you’ve been a foal, and-”

Twilight let out a gasp, cutting her off.

“WHAT!?” she howled in outrage, teleporting in front of her former mentor with a flash of pink and shoving her face in Celestia’s.

“W-well, I mean, Twilight, who does that!?”

Twilight scoffed in response, backing up a bit with  her eyes narrowed.  “Celestia, I saw you sucking off Discord’s hands when he was a statue. How dare you call me weird.”

“I… uh… that is absurd, Twilight!”  It was Celestia’s turn to feel blood rising to her cheeks.  Memories suddenly wafted to the forefront of her mind and she struggled to push them down.

“As if I… and a statue… just absurd!”

Twilight raised her eyebrow, standing a little taller despite the fact that she was standing in her own seed.  “Yes,” she said.  “It is absurd, but that doesn’t change the fact that you did it.”

“There’s no proof!” Celestia said quickly.  Too quickly.  She needed to recover from this.

“A-and besides.  I’m not here to talk about the possibility that I may or may not have gingerly placed my lips against Discord while he was encased in stone and couldn’t deny me.”  She coughed, hoping in vain that it would distract Twilight from what she’d just said.  “I’m here to berate you for the fact that you pleasured yourself using one of my books!  Honestly, my property was violated and sent back to me by you of all ponies!  When I tasted it and found out it was your fluids I vomited all over my bedroom.  And who knows how many other books you deflowered!  Not to mention--”  Celestia froze, realizing she’d said too much.  Twilight’s eyes were practically popping out of her skull, and her jaw unhinged.

“You… you ate my…”

“Now wait a minute, Twilight!  I didn’t… I mean, had I known I wouldn’t have....”

“You ate my cum?”  Twilight practically shouted.

Celestia cringed inwardly, hoping nopony heard that.  She then thought about how she could avoid answering, but eventually sighed.  “Y-yes… I did.”

“...Did you like it?”

“...what.”

Celestia, did you like it!?”

Once more Celestia found herself in a bad position.

“...maybe…”

Awkward silence then passed between the two, Celestia shifting her hooves uncomfortably as Twilight stared at her with her jaw touching the floor.

After what seemed like hours though, she finally spoke up.

“Could… could you describe it to me?” Twilight asked, looking down with a blush.

“W-well, it was, er, sugary… and tasted like paper…”

“You know what paper tastes like?”

“Don’t ask.”

“Um, okay.”

A ringing began to fill Celestia’s ears as quiet took over once more, but Twilight was quick to speak up once more.

“Well then,” she  added,”Why would you even eat my cum!?”

“I THOUGHT IT WAS ICE CREAM!” Celestia screamed back, flailing her fore hooves all about. “IT’S NOT MY FAULT!”

“Why would you go ahead and eat it then!?” Twilight shouted back, mimicking Celestia’s wacky hoof gestures.

“I was trying to figure out what it was, okay! So I sorta… tasted it…”

“...you just tasted it? No hesitation at all?”

“Yeah…”

“Wow. I’m quite frankly shocked and disgusted by you.”

“Understandable.”

They stood in a stark silence, neither sure what to say.  The boundaries that they once kept sacred as a mentor and student were shattered beyond all repair to the point where it was difficult to meet the other in the eye. But, of course, Celestia managed to utter a few final words to her ex-student.

“... I won’t bring this up ever again if you won’t.”

“Agreed.”

Celestia then backed out of the room and teleported away, Twilight sighing in relief, her blush finally receding now that her former mentor was no longer able to see her. She proceeded to  glance down at her herself and the room around her.  The floor, her bed, her book -- especially her book -- and her body were all coated in a healthy layer of her own secretions.  With another sigh, Twilight realized she was going to have to clean up all of this. Yet before she could even react, she heard footsteps leading up to her door.

“Hey, Twilight?” Spike asked, rounding the corner.  “What was all that about?  Did Princess Celestia--”  He froze upon seeing her room.

“S-Spike, don’t look!” Twilight cried.  Blood surged under her cheeks again, and she clamored to cover something, anything, from the young dragons eyes.

“Twilight, this isn’t fair!” Spike suddenly shouted, sounding more aggravated than anything else.  “How come you get to eat ice cream in your room and I can’t?”
