“Windows...check.” Twilight said to herself as she walked around the main room of her library, glancing around at all the windows, all shut and locked with the curtains closed. “Now the lights, and...check!” she added with a smile as she turned off all of the lights in her library with her magic, before checking off that final item on her checklist.

Giggling softly in excitement, she set the parchment down on her desk and trotted over toward the bookshelves, coming up beside the largest one as her horn glowed once more; her magic aura surrounding what appeared to be a piece of wallpaper covering the end of the bookcase. It folded up nicely and rolled atop the bookshelf, revealing a hidden door behind it.

Next to the handle there was a set of buttons, which Twilight swiftly punched in a 15-key combination into, procuring a couple small beeps before the door opened; the unicorn stepping inside and closing the door again, which caused the wallpaper to unfold again, covering up the door once more. Past this door was yet another door, this one having what looked like the viewing piece of a telescope beside it. The unicorn placed her eye against the piece and waited a few moments for it to work, before the door in front of her opened.

Past that was yet another door, this one with a glass plate beside it. Twilight placed her hoof firmly against it and watched as a red line slowly moved across the glass surface, scanning her hoof, before the final door opened, leading to a spiral staircase. Upon reaching the bottom, the unicorn was finally in her favorite place in the library: Her personal clopping room!

It wasn't very large, more like a bedroom, but on either side of the room were bookshelves with various sex toys on one side, and on the other side, tomes upon tomes of erotic literature. With a grin, she climbed onto the bed and sprawled out on her back, stretching a bit as she relaxed on the soft comforter.

“Mmm, now what to begin with...” she thought, her horn glowing once more as she glanced over at the tons of books on the shelf, picking one out at random and bringing it to her side, while at the same time, levitating over a sizable vibrator from the other bookshelf. “Ooh, just what I wanted...” she thought with a smirk, licking her lips as she glanced across the title, recognizing it as one of her favorite stallion-on-stallion novels.

Already, one of her hooves had slid down between her legs and was rubbing gently over her warm slit, teasing the tender lips while she flipped through the pages, stopping at the first sex scene in the book and beginning to slowly read through it. It wasn't long before she was quite moist inside; her mind filled with images of the lusty stallions in the novel, engaged in rough, yet sweet lovemaking.

Sighing blissfully, she brought her hoof up from her crotch and reached over to the vibrator, switching it on and bringing it back over to her moist entrance, starting to rub the tip of it over the soft lips, eliciting soft moans as she continued to read. In addition to the stroking, she pressed the vibrating toy firmly against her clit a few times, biting her lip softly and groaning in bliss from the powerful stimulation it provided.

Already the tip of the toy was very moist with her sweet juices, her arousal having grown very quickly. After a few more strokes, she gently pushed the toy past her nether lips, slowly penetrating them with the vibrating shaft. “Mmmnh...yeah...” she softly moaned, closing her eyes as she imagined it being one of the stallions in the book slowly pushing his member inside her; the soft walls gently clenching around the toy as it slid deeper inside her.

Her cheeks blushed softly from the pleasure as the toy was halfway inside her now, quickly becoming lubed by her warm juices as her pleasure increased; letting it slide a bit deeper inside her before letting her hoof off of it and grasping it with her magic, starting to push and pull it back and forth, sliding it in and out of her warm snatch. “Oooohh...” the lusty unicorn moaned softly once more, slowly turning over onto her belly in a sort-of doggystyle position as she continued to pleasure herself, further getting into her fantasy of being mounted by the fictional stallion.

Twilight's hips lightly rocked back and forth as well as she put more force before the pushing and pulling of the vibrator, feeling her orgasm approaching quickly from the wonderful sensations the toy provided; one of her hooves reaching down between her legs and pressing her sensitive love button, rolling and rubbing over it firmly.

Feeling her climax rapidly building up, she gripped the blanket softly with her free hoof, moaning blissfully now as she thrust the toy even harder and deeper into her hot depths, which only squeezed the vibrating length even tighter, coating it with more of her warm juices as her impending orgasm grew closer and closer. “Aahh, yes...buck me...!” she moaned, blushing deeper as she really got into her fantasy.

She could feel it coming on now, preparing to let out a blissful moan of pure orgasmic pleasure as she thrust the toy in as deep as she could handle, leaning her head back and-

“Hiya Twilight, what'cha doin'?”

Twilight's eyes shot open as she heard the sudden voice, screaming in surprise and jumping back a few feet just as she orgasmed, the toy sliding halfway out of her along with a flood of her juices, splashing all over the comforter in front of her as she panted heavily, staring with wide eyes as the intruder in front of her, before groaning in annoyance with a slight glare. “Pinkie! What the buck are you doing here?...and how?!”

The pink mare giggled excitedly, sitting down on the bed now and smiling wide. “Hehe, that was funny Twilight! Do it again!” she giggled, oblivious to Twilight's annoyance. “I just came to see what you were up to! Gets pretty boring around Sugarcube Corner during the dead hours.”

“But...what...I don't even...huh?” Twilight shook her head in disbelief, glancing over at the door, which was just slightly cracked open. “How did you even get in here? I've got three levels of security to get in! A secret door, a retinal scan, even a hoof scan! How long have you been here?”

“Oh, only a little while. I just got in using this.” Pinkie smiled, pulling a a strange-looking device out of her puffy mane, looking like some sort of white-colored metal arm with a light on the end. “You gotta think with portals, Twilight! But that's besides the point.” she continued, tossing the device away, smashing it to pieces as it hit the floor. “Whatever you were doing, it looked like fun! Can I play? Huh, can I can I?”

Overwhelmed by all the sudden information, Twilight groaned, rubbing her forehead and glancing up towards Pinkie again. “Fine...you certainly owe me for interrupting.” she spoke, sliding the sticky vibrator completely out of her wet snatch and turning it off, tossing it aside. “I suppose I could use a hoof, though...from what Dash tells me, Pinkie seems to have infinite energy.” she thought, glancing over at the shelf and spotting a large double-dildo, something she hadn't gotten the chance to use yet.

“Ooh, what's this you're reading? Is it Fifty Glades of Hay?” Pinkie interrupted Twilight's train of thought as she picked up the open book and began to glance over the words, only to find the book torn from her hooves by Twilight's magic, watching as it returned neatly to the shelf.

“No, that book is for old mares, Pinkie.” Twilight sighed, bringing down the new toy from the shelf with her magic, setting it down on the bed. “You said you wanted to play with me, didn't you? I've never gotten a chance to use this toy, before. And since you're here...why not now?”

The pink mare grinned wide seeing the long toy, nodding eagerly toward Twilight. “Hehe, yeah! I love these, Twilight! Dashie always wants me to use 'em, like every time! She needs to try something different.” she replied with a giggle.

“I assume you don't need any instruction, then...?” Twilight asked with a slight blush, moving the toy over toward Pinkie before turning around and getting into the same doggystyle position she was in before, raising her flanks nice and high for her friend.

“Of course not Twilight, I'm a pro! An expert! You can count on your auntie Pinkie Pie!” Pinkie giggled, standing up and grabbing the toy, before pushing it firmly into her own warm entrance, cooing happily from the pleasurable feeling. Within moments she had mounted Twilight just as a stallion would, smiling down at her as she gently held onto the unicorn's shoulders. “Hehe, ya ready, Twi?”

“Mm...yeah...go ahead.” Twilight spoke softly, somewhat embarrassed at Pinkie's cheerful attitude even during sex, closing her eyes and resting her head on the bed as she waited for the Earth pony to advance.

“Okay then, here it comes!” Pinkie replied, before bucking her hips forward, penetrating Twilight rather roughly, though luckily she was still very wet inside from her previous orgasm. The unicorn groaned from the roughness, but the pain was quickly replaced by pleasure as Pinkie immediately began to firmly thrust her hips, pounding Twilight's pussy roughly.

“Aahh...P-Pinkie...!” Twilight moaned, gripping the bed to keep herself steady as the other mare fucked her, feeling her friend's hips smack against her firm rump with each thrust. “N-Not so rough!”

“Oh c'mon Twi, I saw how you were playing with yourself!” Pinkie giggled, smirking playfully as she continued her hard thrusting, keeping a firm grip on the unicorn below her. “You like it rough, don't you?” she teased, feeling a bit of Twilight's juices splashing onto her crotch; her own insides becoming very moist from the pleasure of the toy sliding a bit back and forth inside her.

“Nnnh...ooohh!” Twilight moaned in reply, blushing deeper as she enjoyed the pink mare's treatment, her insides squeezing tighter around the toy as it continued to pound her deep and hard. Once more, her hoof reached back between her legs and began to tease her sensitive clit, only adding to her pleasure as another orgasm slowly built up. The greater lubrication her juices provided only prompted Pinkie to put even more force behind her thrusts, really pounding the lustful unicorn now.

“Mmmhehehe, you're getting so wet Twilight...and so am I...hehe...this is so much more fun with you than with Dashie! She'd usually tell me to calm the buck down by now!” The pink mare giggled between her soft moans and panting, her own pleasure building up more as the toy slid back and forth inside her even more, though her soft walls continued to keep a tight grip on it. “We need to...ooh, do this more often!”

“Nnnh, why does this mare not have a “Mute” function?” Twilight groaned in her mind as she tried to ignore the pink mare's constant jabber and focus on her own pleasure, rubbing and pressing her love button more firmly as she felt her second orgasm coming on very quickly from the rough thrusting, gripping the bed a little tighter with her free hoof and biting her lip gently.

Pinkie wasn't too far from hers either, panting a bit more as she kept up her hard thrusting, Twilight feeling the mare's breaths on her neck as the pink hooves continued to firmly hold onto her shoulders; both of their crotches damp with each others love juices by now as well. “Ooh, my party cannon is about to blow!” Pinkie moaned, blushing softly now as well, feeling her orgasm coming on quickly.

Her unicorn friend was already there though, letting out a blissful moan as her pleasure climaxed, pressing her clit firmly as her hot insides squeezed the double-dildo tightly and soaked it with a fresh wave of her hot juices, some of it splashing out against Pinkie's crotch as well, only adding to the moisture on her coat.

“Nnh, r-ready, aim, FIRE!” Pinkie moaned in bliss a few moments later, giving one final thrust and smacking her crotch against Twilight's, her hips smacking firmly against the unicorn's rump as well as she climaxed powerfully, a surge of her juices splashing out all over the toy and dripping onto the comforter as well, all while she cuddled closely to Twilight, resting her head gently against the unicorn's throughout her climax.

Both mares were left panting in their afterglows, Twilight exhausted from the rough pounding and powerful orgasm she received, still blushing softly as she turned her head to the side, glancing back at Pinkie. “Mm...that was...pretty good, Pinkie...guess I underestimated you.”

“Hehe...never underestimate the sexual prowess of the Pink!” Pinkie giggled in return, slowly getting back up again and sliding her hips back, pulling the toy out of both of their sopping wet snatches. “And I didn't think you'd be able to take it that rough, Twilight! You don't really strike me as the durable type. Guess all those years with the princesses really paid off for ya, huh?” she added with a grin.

“Wait, what?” Twilight blinked in disbelief, shaking her head a bit and staring wide-eyed at Pinkie.

“Hehe, nothing! See ya later Twilight!” The pink mare poked her tongue out playfully, before hopping off the bed and over toward the door, swiftly leaving the room. Twilight rubbed her head softly, still somewhat confused at her friend's strange knowledge, but shrugged as she began to clean up the mess she had made.

TEH EDN.

Much better planning this time~ I'm getting good at this!
