Spike nervously adjusted his sunglasses as he stood in front of the Ponyville library. He cautiously moved towards the front door, trying to make as little noise as possible. A chilly night breeze rustled his coat, before dying down once again, and leaving behind an uneasy silence.
Swallowing nervously, he grabbed the door handle, turned it slowly so as not to make any noise, and gave the door a gentle nudge, causing it to slide inwards, revealing complete darkness inside.

“Twilight?” he called nervously into the blackness beyond. There was complete silence.
He carefully moved one foot across the threshold, and then when nothing seemed to be attacking him, he followed with the other.

The moment both his feet were inside the library, the silence was shattered violently by the sound of the door slamming shut behind him, and he found himself surrounded by complete darkness.
He turned around to where he thought the door would be and fumbled for the handle. Finding what he thought to be the handle, he tried to turn it, but it wouldn’t budge. The door was apparently locked by some sort of magic spell.

He felt beads of sweat starting to form on his forehead, as he dug through the pockets of his coat looking for his lighter. Finally, his claws touched something rectangular and metallic, and he grabbed it, pulling it out of his pocket. He flicked the top open, and operated the wheel, causing a spark to ignite the wick.

Holding the lighter out in front of him, he could see massive walls of books towering in front of him, forming a maze of sorts around the study area. He took a few cautious steps closer to the book maze, and stuck his head around the corner to see what lay beyond. Nothing but books as far as the eye could see.

He stepped inside the maze. Nothing happened. He nervously continued to move through the maze, expecting something to jump out at him every time he passed a fork in the maze. After a while he was starting to wonder why he hadn’t yet reached the end of the maze. The library wasn’t even supposed to be this big. He continued to move inwards, only occasionally turning back to take a different path as he encountered a dead end.

The walls were starting to look increasingly familiar. Was he going in circles?
He gave one of the walls a kick, but not a single book budged. They had to be held in place by magic, he presumed.

Finally, after having wandered the maze for some time, he saw a faint purple glow in the darkness at the end of the passage. Excited by this sign of progress, he moved towards the light, even more cautiously than before. He could now make out the shape of the light - that of a horn, and the silhouette of a pony hunched down over a book.

As he approached, he could see the outline of the pony beginning to move, slowly raising its head, revealing two dimly glowing eyes staring directly at him. His heart skipped a beat. He could feel a sense of dread spread throughout his body, as the glowing dots pierced his very soul with their gaze. The glint of teeth could be seen, as a wide creepy grin spread across the pitch black silhouette’s face.

Desperate, Spike reached into his pocket for the Holy Handgrenade of Antioch, but all he found was a hole in his pocket. The horn was beginning to flare up dangerously, as if preparing some gruesome spell, and he felt an unseen force gripping his arms and legs, locking him in place. Paralyzed with fear, he watched the horn’s glow increase in intensity, now emitting an audible humming noise and occasionally crackling as sparks shot out from it. And then the world exploded. Excruciating pain filled his entire body, as he felt himself being ripped apart. He panicked.

---

An ear-shattering girly scream worthy of Marv pierced the air. Spike shot upright, dripping with sweat and gasping for breath, his eyes wide with fear. Looking around, he realized he was not in the library. It must have been a dream. Like a wave, everything started coming back to him. His heart was still racing, but he was relieved by the realization that it had only been a nightmare.

Beside the bed, he could see Fluttershy’s quivering rump and tail sticking up in the air as she cowered, her front hooves covering her face, trying to hide behind her nightstand.

Spike sighed. “It’s all right Fluttershy. It was just a bad dream.”

Slowly, she raised her head, got back on her legs.
“Um... are you all right?” she asked, a worried expression on her face.

“Yes, I’m fine. I just had a nightmare.” Spike replied, taking a deep breath.

A pungent smell stung in his nostrils. He sniffed the air around him.
“Um, Shy? I think we need to change the sheets...” he said.
“... and take a shower. It smells like a public restroom in here.”

---

After taking a shower with Fluttershy and having breakfast, Spike decided it was time to face his fears.
He couldn’t stay away from Twilight forever - and he really didn’t want to either, as she was his best friend. He said goodbye to Fluttershy, and she wished him good luck as he stepped through the front door.

The previous night, he had told Fluttershy about the uncomfortable situation with Twilight. She hadn’t said much, except the occasional “Oh, my...”, but he could tell she felt both sorry for him, and relieved that she wasn’t the sole cause of his problems.

When he had described how he had fucked Twilight from behind, and she had vomited all over the pillow while pissing herself around his cock, Fluttershy had started blushing from arousal, and they had then retired to her bedroom and had hours of filthy sweaty piss sex, before falling asleep from the exhaustion.

He rubbed his face to get rid of the perverted grin that had formed on it as he remembered the previous night’s events.

---

Finally, Spike found himself standing in front of the Ponyville library. The hour of truth was upon him.
He swallowed nervously and knocked on the door a few times. Nothing happened.
He tried knocking again, harder this time, and waited a while. Still no reply.
He grabbed the door handle and tried to turn it, but it didn’t budge. The door was locked. Maybe Twilight was still asleep?

* Cue Mission Impossible theme *

Spike couldn’t be bothered to stand around outside all day waiting for Twilight to open the door. Running around to the right side of the tree, where the second floor balcony was, he hammered his claws into the wood and started to climb up the gnarly wooden wall. Upon reaching the balcony, he detached one of his arms from the tree and grabbed onto the railing, and then once he had a firm grip on it, followed with his other arm. Climbing over the railing, and dropping down onto the balcony, he peered through the glass door into the second-floor study, looking for any sign of life. The room beyond was dark, and he couldn’t see much, but he was unable to spot any sign of movement, or hear any noise from within.

Jamming one of his scales into the crack between the door and the left side of the frame, where he knew the lock to be, he pushed it upwards and gave the door a nudge, causing it to slide open. He stepped inside, closing the door behind him, grabbed a candleholder with a half-burned candle in it off Twilight’s writing desk and lit it by carefully puffing a small flame onto the wick.

“Hey, Twilight, are you here?” he called out into the dimly lit room. There was complete silence.

Holding the candle out in front of him to see where he was going, he slowly started to make his way up the stairs to the sleeping area. When he reached the top of the stairs, he could make out a pony-shaped object on Twilight’s bed. Was she still asleep?

He tiptoed over to the bed, hopped onto it, and held up the candle to shed some light on Twi, who was lying on the bed with her face pressed into the pillow. Her mane and tail were a mess - presumably from her tossing and turning in the bed, and a faint smell suggested that she hadn’t bathed for several days.

“Twi?” Spike said, giving her a soft poke in the shoulder.

The purple pony stirred, raised her head out of the pillow, revealing a wet spot underneath, and opened her eyes. Her eyes were red and her nose was running - she had obviously been crying a lot.

He wasn’t quite sure what he had been expecting, but it wasn’t his. It was obvious that the situation had hit her much harder than it had hit him.

“Twilight, we need to talk.” he sighed, his previous fear of what she might do to him now overshadowed by his pity for her.

Her eyes began to tear up. “I’m so sorry, Spike!” she almost yelled at him, clenching her eyes shut as tears streamed down her face.

Spike was confused. If anything, he was the one who should be sorry, especially after what had happened the previous day. “What for?” he asked.

“Taking advantage of you after the party...” came the reply, in between sobs.

“You know, if anyone should be sorry, it’s me.” Spike replied. “You were far more drunk than I was, and I could have refused your advances.”
“I didn’t, because...” he continued, swallowing nervously and trying to figure out the best way to word his feelings. “... because, deep down I have always been attracted to you, and when you kissed me, it made me realize it more than ever.” he admitted, blushing and twiddling his thumbs as he said it.

“It wasn’t just the alcohol...” Twilight said, turning her face away from Spike as she began tearing up again. “You know, I’ve never had a stallionfriend...” she began, and was cut off by a sob.

Spike didn’t know what to say to this, but he knew. He remained silent, waiting for her to continue.

“Except for the occasional glimpse of Big Macintosh at Sweet Apple acres, and passing random stallions in the street, you’re the only male company I’ve ever had...” Twilight went on. “I used to think of you as a little brother... and I still do... but as we grew older, I started to have other feelings as well...” she said, turning back to face him. “... and fantasies. Dirty fantasies, inappropriate to have about a sibling!”

As she finished her last sentence, her ears started to twitch and her pupils shrunk and began to slide lazily apart.

Spike winced at the expression on her face as she said the last sentance. He recognized that face, and knew she was about to have a mental breakdown. He had only seen her like this once before, when she had forgotten to write a friendship report to Celestia, and was unable to find any problems to solve and write one about. As a result, she had nearly started a civil war in Ponyville, and Princess Celestia, who he had written to earlier that day, had been forced to intervene. He didn’t want anything like that to happen again.

“Snap out of it, Twilight!” he yelled, grabbing her by the cheeks, shaking her head and staring directly into her eyes. “Don’t feel bad about it. I’ve had fantasies about you as well...”
“I just never thought you would ever think of me that way.”
“... and I enjoyed it.” he said, smiling. “Well, not the awkwardness that followed, but you know... the act itself.” he added, blushing slightly and letting go of her face.

“And well, I’m just stating the obvious here, but... we’re not actually blood related.” he said. “Heck, we’re not even the same species.”

During his monologue, Twilight had gradually regained her composure.
“You’re... right I guess.” she said, her voice calmer now.
“... but what about you and Fluttershy?” she asked, curiousity in her voice.

“Oh, that.” Spike replied, having almost forgotten about that whole thing as he went on about their previous encounter. “There’s nothing serious going on between us, if that’s what you’re wondering. Just sex.”

“I just... never imagined Fluttershy doing anything... sex-related.” Twilight said in a thoughtful, but almost cheerful tone. “She’s just so... sweet and innocent.”

“Oohhh... trust me, there’s a lot you don’t know about Fluttershy.” Spike said, straining himself to keep a straight face. “She may seem sweet and innocent most of the time, but when she gets... in the mood... she’s a real beast.”

“It’s always the quiet ones, isn’t it...” Twilight said, almost giggling now. “You know, when I saw you two... doing things... my first thought wasn’t why my little brother was fooling around with one of my best friends...” she said, pausing for a moment to regain her breath.
“... it was jealousy. I wanted you all to myself.”
“And that realization bothered me almost as much as what happened between us.”
“Silly isn’t it?” she added, giggling.

“Not really. I’d probably feel the same way if I saw you with a stallion.” said Spike honestly.

Twilight’s reaction to this was unexpected. She embraced him in a tight hug, tears streaming down her face once more. “You have no idea how much it means to me to hear you say that.” she said, sobbing over his shoulder. As much as he preferred to keep a straight face, even Spike couldn’t fight off the emotional impact of the situation, and soon he too was crying manly tears over Twilight’s shoulder. Not tears of sadness, but of happiness that the uncomfortable situation had been resolved and that he and Twilight both shared a mutual love for each other.

For some time they just lay on the bed, embracing each other and crying, soaking both the bed and each other in tears. After a while, their sobs ceased, and they released their grips on each other. Spike wiped the tears from his eyes. When he looked at Twilight’s red-eyed face, wet with tears, she seemed more beautiful than ever before, despite - or perhaps even because of - her unbrushed and somewhat dirty mane.

Without hesitating, he placed his hands around her neck and pulled her towards him, locking his lips onto hers in a passionate kiss. She immediately responded by thrusting her hot wet pony tongue into his tiny mouth, and toying with his as he tried to do the same. After enjoying the sensation of kissing and probing each others’ mouths for several minutes, they ended the kiss, and sat down panting on the bed.

Spike felt as though his body was about to burn up. He could hardly believe how anything that wasn’t actual sex could feel this wonderful, and judging by its current rigidity, neither could his dick. Twilight’s blushing face and bedroom eyes told him she felt the same way. She rolled onto her back, spreading her hind legs and revealing her dripping wet marehood to him. As he stared deep into her eyes, it was almost as though they told him “Come get some, loverboy!”.

Disregarding her body odor, he positioned himself in front of her and began to passionately rub her sexy purple flanks. Her hind legs began to twitch with pleasure as his hands worked their magic, and she moaned softly, biting her lip. Her already very moist pubic area became increasingly so as he went on.

When finally, he could control himself no longer, he grabbed his throbbing tool and began to rub it up and down her furry wet slit, sending lightning bolts of pleasure up his spine with each rub. Her face was almost red from arousal, and her eyes were closed, as she let out a moan of pleasure.

“Oh, Spike! That feels sooo good!” she managed to stammer out in between her moans and gasps.
“I want you inside me...” she moaned. “Please... put it inside me...”

“You want me to stick what in where?” he asked her teasingly, continuing his rubbing. He wanted to hear her say it straight out.

“I want you to put your penis in my vagina...” she tried.

“Too... medical. Try again!” he said, grinning.

“Uhn~! I want you to put your cock in my pussy!” she shouted, mildly annoyed, almost cracking up as one of his rubs ground down on her clit extra hard.

“Any others?” he said mischievously.

“I want you to put your dick in my cunt!?” she tried again, even more annoyed than before.

“Again?” he said.

“Oh, for the love of Celestia, just FUCK ME... and do it HARD!” she screamed in his face, opening her eyes and staring angrily at him to impress upon him the point that she wasn’t having any more of this bullshit.

“Ookay, just yanking your chain...” Spike snickered, as he positioned his cock, which was now almost completely covered in her slippery vaginal secretions, directly in front of her opening.

Her body stiffened a little, and she gave a yelp of pleasure as he drove his bulging member into her depths, all the way up to its base and started to slide himself in and out of her tight little pony pussy. Enjoying the wet squishy sounds of his cock penetrating her, and the immense pleasure coarsing through his body as her hot slippery insides caressed him with each thrust, he gradually increased his pace as he continued his movements. Putting one of his arms down, he felt around the sheets until his hand found her tail, which was twitching with each of his movements, and pulled it up between them. Her moans grew even louder as he gave it a nice hard tug, enjoying the sensation of the soft hairs tickling his balls with each of his thrusts as it involuntarily flicked back and forth between them.

“Wait...” Twilight said, opening her eyes and causing Spike to slow down his movement. “I need to use the little fillies room!”

“You have to pee?” Spike asked.

“Yes... sorry...” she replied, folding her ears and giving him an embarrassed apologetic look.
“I haven’t gone since last night... if I don’t I don’t know if I’ll be able to hold it in when I... you know...”

A satisfied grin spread across Spike’s face. “Just do it here.” he said.

“But that would make the sheets all wet and dirty...” she argued.

“The sheets are gonna get dirty anyway.” he countered. “...and can’t you just evaporate the moisture with your horn afterwards?”

“Well... I suppose so...” she conceded.

“Try to hold it in until you cum. It’ll feel even better that way.” Spike suggested, trying to fight off a perverted grin.

“Okay... I’ll try...” she said.

Resuming his movements, Spike placed his hands on her belly where he knew her bladder would be and began to massage it, sliding his fingers through the soft fur above her crotch.
She let out a loud moan, and he felt a small amount of moisture escaping her as he did so - the mere thought of which greatly amplified his pleasure as he slid in and out of her.

“Uhhh... Spike... that feels so good...” Twilight moaned as he continued to rub her tummy.

He could feel that he was close to coming, but was determined to make Twilight come first. Her orgasm would undoubtedly set him off, and would greatly increase his pleasure - especially if she released her bladder at the same time.

“Almost there... don’t know how much longer I can hold it in...” she gasped.

Moving his right hand down from her bladder, he wedged his index claw into her opening and began to rub furiously at her button, sending shivers of pleasure through her body, and making her gasp loudly.

“Spike! I’m...” she gasped, and then finished “... coming!” as a thundering orgasm shook her body. Her back arced upwards, her legs began to spasm and her tail began to twitch furiously between their crotches, as her pussy began to contract and convulse around him, and she let out a euphoric scream of pleasure.

Each of those things alone would have been enough to push Spike over the edge at that point, and the combination of all at the same time sent him into an explosive climax. It took all of his willpower not to pass out as his balls began to contract, unloading their precious content into Twilight’s womb.

Another gasp escaped her muzzle, as she released her bladder, still at the height of her orgasm, sending gushes of warm yellow liquid splashing onto Spike’s crotch, and forming a pool around his feet on the sheets below before slowly being absorbed into the mattress.

“Ooohhh Celestia, yeeees!!!” Twilight screamed, her body quaking and spasming uncontrollably with pleasure.

The warm wet sensation, combined with the warm sweet scent of Twilight’s urine wafting up from the bed sent another lightning bolt of pleasure rocking through Spike’s body, and he found himself unable to stop himself from letting out a loud groan of pleasure as he continued to fill up Twilight while pounding her tight little pony pussy, and making wet squishy sounds as her golden nectar flowed around his cock. As her womb filled up and began to overflow, blobs of his sticky white stuff began to mix with the flowing urine and settling as tiny white spots on the sheets.

Finally, as their orgasms began to subside, Spike ceased his thrusts and collapsed face down onto Twilight’s belly, panting. He felt Twilight’s insides giving a few last twitches as her climax faded, and the flow from her bladder slowed to a drip. Looking up at her, he could see her face - her eyes half-closed and her tongue lolling out of her muzzle as she panted from pleasure and exhaustion.

When she regained her breath, she raised her head, looking down at Spike.
“Oh my Celestia, Spike... you’ve done this before haven’t you?” she asked, quickly adding “I mean, except for that one time with me...” and blushing as she said it.

“Mmmf hmmf.” came Spike’s muffled reply, as he spoke with his face pressed into her belly, causing her to giggle softly as his breath tickled her.

He raised his head again to look up at her. “Are you gonna change the sheets?” he asked.

“Forget the sheets. They’ll still be there tomorrow.” she replied.
“Just hold me Spike...”
She turned her head around, blowing out the candle and once again shrouding them in darkness.

Placing his arms around her waist, and holding her tightly, Spike began to drift off to sleep.
As he lay there, he realized that he felt something new inside him that he hadn’t felt for any of the other ponies - not even Rarity. He felt that he would do anything to make Twilight happy. It was like a lump in his stomach, and it almost made him cry again. She had always been like a sister to him, but now she was so much more.

“Could this be... true love?” he wondered, as he slowly drifted off to sleep.

---

From that day on, Spike would always sleep in the bed with Twilight.
His basket was left there, however, to avoid any uncomfortable questions from inquisitive friends and guests.

THE END (Well, until next chapter, anyway...)
