Living in the Library

As the school day came to a close, Twilight reflected on all the challenges she had faced that day. It was disorientating enough becoming some sort of odd creature and her boyfriend becoming a dog, but meeting others of the same species that resembled several people she knew back home and in a school of all places? It was all very bizarre, not to mention she had to somehow find a way to blend in in such a short amount of time, she didn't know the first thing about how the weird things at the end of her arms worked and they were the most basic tools that these creatures seemed to utilize. She was lucky in a sense that this place had a library and some kind of weird box that had moving pictures, it meant she could do some limited research.

The "creatures" in question were known as humans and like Twilight had guessed, they were some form of hairless ape. From what she had gathered their society worked much like Equestrian society did, only they were more advanced, Twilight also learned that the things at the end of her arms were called "hands", she wasn't all that surprised to find that they worked much like Spike's claws had worked back when he was a dragon. Before she could start thinking back on Sunset Shimmer and her plans for the next day she realized something, she didn't have anywhere to go for a good night's sleep. There were certainly no living facilities at the school and she didn't exactly know anyone well enough yet to ask if she could stay over, Twilight was also in the rather unfortunate position of not possessing the knowledge of the existence of hotels. She did consider briefly going back to Equestria for the sake of sleep, but didn't want to chance it in case Sunset Shimmer had some kind of contingency plan in place that would prevent her from coming back to retrieve her element of harmony.

She put down the book she was reading and after letting out a yawn she gasped at just how tired she was and said to Spike "I haven't even thought of where we're going to sleep tonight"

Spike looked at her and with a smile smile began walked to another part of the school library as he said "Way ahead of you". After following Spike to what was most definitely the most secluded and very dusty part of the library, Spike pulled away a cloth to reveal a makeshift bed he had made out of library books, he coughed and said "It's a little bit dusty, but it doesn't seem like anybody comes up here".

Twilight smiled at his ingenuity and said "It's perfect Spike".

As they both sat down Spike went "So, how did your research go?"

Twilight held up a big blue book with a picture of a yellow horse shoe on it and said "Well, I found this book, it's called a year book, it seems to be something they use to keep a record of things that have happened at the school, look..." Twilight pointed to a picture of a group of girls that they were both very familiar with "That's Pinkie Pie, Rainbow Dash, Applejack, Fluttershy and I'm gonna bet the girl on the far right is Rarity".

Twilight waited for a lovey dovey response from Spike, but all he said was "Huh, interesting photo".

Twilight shrugged, assuming and relieved that clearly that ship had sailed for Spike and went "It's interesting because they look like they're friends"

Spike, mishearing her despite having the ears of a dog said "They do look like our friends, but I thought we'd figured that out already?"

Twilight clarified "No, I mean they look like they're friends with each other, but it doesn't seem like they're friends now", Twilight was clearly a bit disheartened that friendship didn't prevail everywhere.

Spike didn't help when he said "Not so much".

Twilight laid back on her temporary bed and said "I just can't help but get the feeling that Sunset Shimmer had something to do with it"

Spike agreed "I wouldn't put it past her..." as he started dragging the cover back up to use as a makeshift duvet "But she wanted your crown because she's planning on doing something even worse, if you're gonna stop her you have to focus on making friends here, you can't worry about why these girls aren't friends anymore". Spike laid down next to Twilight before continuing "Even if they do look like your Ponyville friends".

Twilight smiled and gave him a hug "You're right Spike, eye on the prize".

Library Lust

The view they both had of the sky was magical, laying there side by side just gazing at the stars, it all felt very romantic for them, as if they were on their very first date all over again. Their first date had been awkward to say the least, they recognized that they had developed a parent/child dynamic over the years and that it felt odd and just a tad naughty to be sneaking off for secret dates, but once they got past that, the rest was easy. Their first date was actually in the Crystal Empire in the arctic wasteland, not a traditional setting, but they weren't ready to reveal themselves as becoming partners yet, besides they had taken all the necessary provisions and just like they were doing right now, they had simply allowed themselves to gaze up at the night sky.

Twilight smirked as she remembered exactly what they did after spending a few minutes looking at stars, then again that particular activity usually had her seeing stars anyway! Spike knew that particular smirk, Twilight always made that smirk just before becoming intimate, he turned to her and said "So Twilight... since we are alone up here, how about we get a little close?"

Twilight blushed with an awkward smile, but caught herself before saying yes immediately like she normally would. She laughed it off and said in a not-so-convincing tone "Uh... not tonight Spike! Maybe some other time! Back in Equestria maybe! Goodnight!" Twilight turned away and isolated herself from Spike, not intentionally, but more on reflex.

Spike sighed, Twilight's freak-outs were a common occurrence, but that didn't make them any less frustrating "OK, what's wrong?"

Twilight turned back to him and said "Oh... er, nothing Spike I'm just... just not in the mood that's all", she didn't know why she expected Spike to accept that bullshit excuse, she'd never been "not in the mood" throughout their entire relationship.

Spike raised an eyebrow and said "You expect me to believe that? Come on Twilight, I can tell when somethings bugging you, but I can't help unless you tell me".

Twilight sighed, she knew Spike would see right through her and wouldn't be satisfied until he had helped her solve her problem, he was sweet like that. "Well Spike, it's just that... I'm not sure if I feel comfortable having sex with you while we are here"

Understandably Spike asked "Why not?"

Twilight said "Well first of all we are in a library and second of all you're a dog so having sex with you would be bestiality".

Spike had the perfect rebuttal to those two hang ups "Well Twilight, need I remind you that we used to live in a library? Besides any sort of fluids that may be involved in our love-making is only gonna fall onto unread hardback books that nobody reads", Twilight thought to herself, he did have a point there, it was the second issue that would be the real challenge though. "What does me being a dog have to do with it? It's not bestiality" Spike claimed.

Twilight went "What are you talking about? Yes it is, we're two different species, having sex with you would be wrong".

Twilight had made a fatal error there, Spike was legitimately offended and said "Oh, so I suppose a pony being with a dragon is also wrong and immoral, is that correct?!"

Twilight gasped in shock "No no no no! Not at all! Anyway, you're sentient as a dragon!"

Spike came back at her with "I'm sentient as a dog too! You could argue that you don't even need to ask for consent, which let me remind you, is the one and only reason that bestiality is illegal in Equestria. Why do you think Fluttershy fucks so many of her animals and hasn't been arrested? It's because she can talk to them and if she or any of her animals are in the mood, the language for consent is there. Fluttershy doesn't rape her animals, that's not exactly part of the welfare side of taking care of our fellow creatures".

Twilight mulled over everything Spike had said, she couldn't fault him on his logic. All the available information swirled around in her head until she came to the only conclusion she could draw, if she could be a pony and fuck her dragon, then she could be a human and fuck her dog. It would certainly be a new, exciting and kinky way to experience sex. Twilight adopted a seductive look and said "Alright big boy, why don't you lay on your side and I'll give you a nice blowjob to get things started, hmm?" There was the Twilight Spike knew and loved, he smiled and did exactly as she said, his cock already beginning to swell.

Book Bed Blowing

Spike's tail started wagging as Twilight got herself closer to his rapidly growing erection, she tried to ignore how different it was to what she was used to, different size, shape, color, smell, she only hoped it still tasted nice. With her left hand she gently cradled his soft heavy balls and easily guided his cock into her mouth, her lips gliding along his slippery length until she was all the way down to the base, she mentally thanked Spike for helping her train her throat to accept cock so willingly otherwise she would never have been able to deep-throat without gagging every three seconds. As she began to blow him with her eyes closed and her hand clumsily massaging his pent up sack, she found that not only did his dick taste good, but it actually tasted a little better than usual. Quickly getting a taste for it, Twilight sped up her back and forth motions and got her tongue around as much of his cock as she could, Spike certainly wasn't complaining as he panted wildly, his tongue hanging out and drooling onto the long neglected books below.

Twilight moaned gently as Spike soon reached full hardness under her oral ministrations, it was just then that Twilight had an epiphany. There was a new sexual experience that Spike would only ever get to enjoy while he was in this form, because there was something that all mammals had that reptiles didn't have... a prostate. Twilight wasn't exactly stupid when it came to sex, she had her kinks and she knew that the prostate could provide extreme pleasure to a male if it was properly tended to, keeping up the pace of her blowjob she reached her right hand down to her pussy which had been steadily becoming more and more wet throughout the duration of their extremely intense foreplay. She slid her middle finger inside and pumped it in and out a few times to make sure it was nice and slick for when she was ready to treat Spike to a special kind of pleasure that he might never have the chance to ever feel again. Biology was a bitch sometimes.

When Twilight was satisfied that her finger was suitably lubricated, she moved her hand away from her pussy and brought her middle finger up to just underneaths Spike's tail before gently pressing the tip directly onto Spike's tight virgin asshole. The sensation of something pressing on his rear entrance momentarily distracted Spike from Twilight's ongoing assault on his cock, still seemingly having the energy to not falter for even a second despite having to concentrate on gaining access to his ass so she could stimulate his prostate and also hungrily blowing him at the same time. "T-Twilight... what are you-" Spike's eyes went wide as the tip of her finger slipped into his asshole and slowly began delving deeper and deeper inside his back door, it's not as if he was entirely opposed to the idea, it was just surprising to say the least, though judging by the way his cock throbbed and started leaking more pre-cum while his balls ached and churned to produce a huge load, it seemed he was enjoying it.

However, Twilight could tell by the clenching of his anal walls down on her intruding finger that he was not as relaxed as he could be, he had loosened up once he accepted that the penetration was enjoyable, but it was still a relatively new feeling. In an effort to calm his muscles she stopped bobbing her head and simply allowed his dick to just lay in the warmth and moisture of her welcoming mouth, which worked to a certain degree, though it seemed she wouldn't have to do the moving soon anyway, for when her middle finger was all the way in and she located his prostate, the careful stroking she applied spurred Spike into action and his hips started thrusting on reflex. Due to their position, his attempts to fuck Twilight's face weren't exactly successful, nevertheless he was panting with a dreamy look on his face, his tail was wagging and he felt fucking incredible.

Being a dragon, Spike had never been able to experience much anal play, let alone prostate play, he almost wished he could stay a dog in Equestria if he got to experience this kind of depraved and taboo sexual pleasure. As much as he wanted to enjoy Twilight's rubbing on his prostate as much as possible, there was only so much he could take, with a howl he released rope after rope of his thick heavy load into Twilight's soft velvety mouth. Twilight allowed his spunk to collect and sit in her accommodating mouth, savoring the salty and bitter taste on her tongue as her cheeks ballooned out slightly as Spike deposited the last few shots of his seed inside her. His cum wasn't too dissimilar to how it tasted when he was a dragon, there was a slight hint of a difference there for sure but Twilight couldn't quite place what exactly it was, Spike's cum was an acquired taste which she had grown to love over time, she figured that all cum probably wasn't suitable for those tasting it for the first time, but that it was practically a replacement for all other liquids to the average cum guzzler.

Once Twilight was sure Spike's balls had no more to give, she ceased her stimulation of the prostate and removed her finger from his ass while she slid her lips off of his cock and swallowed down his warm creamy jizz. As she caught her breath and regained the ability to speak she giggled and said "Spike, as much as I love your natural taste, I think it might be worth exploring the benefits of eating pineapple".

Spike returned the laugh and said "Fair enough, nice going on the prostate there, that seriously made me nut so fucking hard"

Book Bed Banging

Twilight smirked, she always felt smug when Spike complimented her sexual prowess like that "Glad to hear it, I take pride in my skills. Though hopefully I wasn't so good that this was just a one-and-done deal?"

Spike said "Oh really? Well how many more were you hoping for?"

Twilight smiled wryly and said "Well..... just one would be fine, but I was thinking, if you're a really good boy..." Twilight leaned in close to his ear and whispered "I'll let you put it in my butt". Spike's cock was reacting already, the promise of more fun was enough to rekindle the flames of lust in his groin. Twilight noticed and with a sensual tone said "Looks like someone is in agreement, so Spike, ready to really and truly empty yourself dry inside me?"

Spike said "You sure you can handle the knot?"

That was a point, Twilight had been so busy when she was sucking him off that she hadn't even registered the knot, seemed liked her mouth could open wider than she thought if she didn't even notice it in her mouth of all places. She understood that if Spike was going to fuck her pussy and then her ass, then both times would likely lead to them being tied together in some fashion...... that was really fucking hot. Rather than talking Twilight simply removed her clothes, got on all fours and waved her ass from side to side enticingly. Spike simply rolled his eyes and said "Classic Twilight, well, looks like you're my bitch for the night".

Twilight just bit her lip and said "Mmm... you know it baby".

Spike reared up and hooked his forelegs around Twilight's hips, at this point Twilight was too horny to take note of just how different it was to be a human getting fucked by a dog in contrast to being a pony getting fucked by a dragon, she just needed dick and she needed it now. Spike had a little trouble lining up with Twilight's hole, finding her pussy was the easy part, but aiming his cock towards the actual entrance was the tricky bit. Spike had tried at least five times to enter her with no success, constantly not quite hitting the mark or just missing altogether, Twilight was getting impatient until finally on Spike's ninth attempt he had orientated himself correctly and his cock started sinking into her folds. Twilight moaned softly as she felt Spike push further and further into her hot moist caverns, the walls of her pussy were so sensitive she swore she could feel Spike's member pulsating as his body once again sent all the necessary signals to his brain saying that he needed a raging hard-on with nuts ready to be drained.

Once Spike had gotten as far in as he could go, with his hips firmly pressed up against Twilight's ass, he began fucking her with as much might as he could muster, he knew Twilight was gonna surrender her ass to him anyway, but he still wanted to feel like he'd earned it by giving her a good hard pussy pounding. This was the kind of fucking that made Twilight see stars without her having to look into the night sky, Spike's cock was hitting all the right spots and all with the right amount of pressure, she could already feel his knot swelling as it was pushed in and out of her constantly clamping pussy. Before long, Twilight had a look on her face similar to Spike, tongue hanging out, drooling and breathing heavily, the only two main differences being her messy hair and crossed eyes. The sex was so rough, so instinctual, so deeply primal and in this case, quite literally animalistic; eventually Spike's knot had swollen to a size where a simple thrusting wouldn't get it pushed into Twilight's pussy, which is why as Spike finally came he pushed forward and with a great amount of force, Twilight's pussy stretched wider and allowed the knot to pop inside, becoming trapped and locking Spike and Twilight together.

Both of their bodies with hot and aching, Twilight was sweating and upon feeling Spike blowing a load into her abused female fuck hole, groaned with fists clenched as she experienced her first orgasm of the night, her pussy twitching as juices built up and leaked around the considerable size of Spike's package lodged in her entrance. As they both expected, when Spike tried to pull out, the knot prevented him from doing so, he was well and truly stuck inside Twilight and would remain that way until his knot deflated. Twilight basked in the afterglow of their coupling, their union of flesh, their incredibly intense and awesomely rigorous steamy sex session, their totally great fuck. As Twilight felt the soothing warmth of Spikes load spilling into her pussy, she was glad that Spike had managed to convince her that having sex with him was the right call, because it so was. She had needed this more than she realized, it was until she started becoming intimate with Spike in their relationship that she realized just how much she was missing out on sex and how therapeutic it was for her in times of need, especially for relieving stress.

With an experimental tug, Spike was confident his knot had now shrunk to a size where he could free himself, as he pulled back his dick was finally released and he dismounted, thoroughly worn out.

Book Bed Booty

"Phew... that thing was really in there huh? Kept me nice and plugged while you defiled my sloppy cunt. I fucking love it when you violate my holes so violently. Oh, speaking of plugs, think you're ready for the final round? Come on, clamber back on top of me and fuck my butt." said Twilight. This girl was insatiable and horny beyond all reason.

Spike sat down and said "Phew, I dunno babe... I think I need a break"

Twilight was actually slightly disheartened at hearing Spike say that "Are you saying you don't want this ass?" Twilight shook her butt from side to side and gave her right ass cheek a slap to make it jiggle just before grabbing hold of both her cheeks and spreading them apart to show Spike her pucker, she knew all the right ways to seduce Spike and press his buttons.

Spike, staring with unquestionable desire went "Well... I didn't say that, but I think the little guy needs a little bit of encouragement before he'll be ready, know what I mean?"

Twilight let go of her cheeks and turned around with a slightly ravenous lust shining in her eyes, with a smile she simply said "Well then why didn't you just say so hot stuff?" Twilight crawled over to him and immediately reached underneath to wrap her fingers around his semi-hard member, beginning to softly pump it to get Spike back to full hardness.

After a few seconds Twilight had an idea that she knew might speed up the process of making Spike fully erect again, or at least erect enough to penetrate her butt. She let go of him and said "Turn around, face away from me", Spike did as he was instructed and waited for whatever it was Twilight was planning to do, this was turning out to be possibly the longest night of sex they had ever had. Twilight once again took hold of his dick and continued jerking him off, using her other hand to cup his balls and roll them around her fingers, but the part she was certain would make him hard much faster was when she pressed her tongue up against his asshole and started licking. Needless to say Spike hadn't expected Twilight to do that, she was full of surprises tonight, but it certainly had the desired effect, his tail was wagging and his cock was becoming more and more engorged by the second.

Twilight could feel that he was ready, but decided to finish off the foreplay by firmly pushing her tongue inside his ass, before withdrawing and letting go of his dick. She turned back around on all fours, ready for some anal sex. "So... think you're ready to get inside my back door?"

Spike was already panting a bit as he said "Honey, I'm so ready you might as well call it the doggy door!"

Twilight giggled, spread her ass cheeks and said "Care to lube me up first?" Spike knew immediately what she meant and thrust his muzzle into her crack and started lapping away at her asshole. Twilight was already enjoying it more than she enjoyed when a dragon tongue was licking her back there, it wasn't as coarse, versatile or flexible as a dragon tongue but it was a lot flatter and wider meaning that only one lick covered her entire hole. After no more than about thirty seconds, Twilight's ass was drenched in saliva and ready for cock, Spike threw himself onto her back and after a couple of false starts, lined up his cock with her ass and rammed himself inside. Twilight let out a long sigh of satisfaction as Spike began pounding her ass, she loved the way his dick stretched out her tightest orifice and by the same token, Spike loved just how tight her rear was, so tight in fact that even though his knot had not grown to full size yet, it was still denied access inside her body. Twilight didn't intend for Spike to not have his knot shoved firmly up her ass "S-Spike! You... oh fuck... you better fucking... oh yeah... fucking knot me now before you're too big!!!"

Spike tightened his grip on Twilight's hips and heaved his own hips forward to get his knot inside Twilight, her hole put up some resistance against the knot from invading her butt and for a brief moment, both Spike and Twilight were worried that he was already to big too fit inside. With some perseverance however, the hole yielding to Spike's efforts and the knot just about slipped inside. The feeling of the not filling her ass caused Twilight to have a mini orgasm and with Spike still being so sensitive, he couldn't hold back his own payload when Twilight's anal walls squeezed around his member, his load this time around was small as he was beginning to run out of fluids, but enough that Twilight could feel and register that he had finished.

As before, they both had to wait for Spike's knot to deflate before he could pull himself out of Twilight's ass. Thinking that they were done, Spike got the shock of his life when, before he could his cock could even begin to go flaccid, Twilight grabbed a hold of it and savagely started jerking him off. "T-Twilight, what are you doing?!" It wasn't that he was necessarily complaining, but he was just bewildered at how Twilight was still going.

Epilogue

Something has gone wrong. We don't seem to have an archived copy of that chapter.

Prologue

When every pony heard that Twilight and Spike had become a couple, they were happy for them of course, but they just found it rather surprising. They weren't surprised because of the inter-species aspect, that was actually very common in Equestria, but the fact that the two of them had a dynamic that they didn't imagine could have led to a romantic relationship, they always viewed them very much as having the same kind of relationship as a mother would have to a son. Nevertheless, the two of them had been in a very happy relationship for quite a while now, they had even reached a point where they were both comfortable becoming intimate in the bedroom sense.

Of course there were some ponies who were very much against the whole thing, saying that inter-species relationships were wrong and against nature, an unfortunate reality that Twilight and Spike had to face together on numerous occasions. It came as a relief somewhat that they had both been called to the Crystal Empire, it gave them some time to relax and be away from all the prejudice ponies of Ponyville, had a certain Sunset Shimmer not turned up to steal Twilight's crown then they could have gotten all the relaxation they needed.

Going through the mirror to try and retrieve the crown was an almost harrowing experience, especially when Twilight opened her eyes to found she had been transformed into some kind of hairless ape that walked upright while Spike had been turned into a dog. It was only after they had gone through the first day at Canterlot high that they encountered the ultimate problem, where were they going to sleep?

Library Love

"Come on, I know you're not done yet, I know you've got one more load in you and I'm not fucking stopping until you blow it! So do it, cum you fucking filthy handsome stud!" That kind of dirty talk was just what Spike needed to shoot out the last remnants of cum stored up in his balls, that final ejaculation was uncomfortable bordering on painful, but he wasn't about to argue against a very determined Twilight. Once her hand was covered in his spunk, she licked it all up and swallowed it down, before collapsing on her back "Phew... that was good, I'm glad you convinced me to do that, I don't know if I could handle much more in this crazy place without taking a good fucking".

Spike chuckled and said "Well, I do have some talents, but I think you've earned one last orgasm before we end the night", without waiting for Twilight to ask what he mean he simply pushed his head in between her legs and start licking her pussy. Twilight simply groaned in pleasure and laid back to enjoy it, placing one of her hands on Spike's head. She was already pretty riled up despite being so exhausted, that coupled with the fact that Spike had a much larger tongue than usual meant her orgasm approached far quicker than either of them anticipated, she moaned softly in an almost whimpering manner as her pussy squirted fluids all over Spikes muzzle. They were now well and truly done for the night.

Spike removed himself from between her legs and they re-assumed their original sleeping positions that they were in before all of the sex, Twilight gave Spike a peck on the cheek and said "I love you".

Spike smiled and said "I love you too Twilight"

There was a pause before Twilight said "We should get married at some point"

Spike, rather than being shocked actually laughed and said "Was that your proposal to me?"

Twilight went "I think the proposal will be just a bit more romantic than that! Let's call it a plan"

Spike once again smiled and said "Sounds like a good plan" then they both drifted off to sleep.

Around the corner in the shadows, hidden behind a book case, Sunset Shimmer hit the "Stop Record" button on her phone and put it back in her pocket as she left the library "Perfect..." she said to herself "Now all I have to do is a little bit of editing, then I'll have a compilation of Twilight having sex with a dog that I can send to everyone in school, that way nobody will be in my way! Who knows? I might even get her arrested!"
