In the human world Spike and Rarity get closer.

An alternate ending to Equestria Girls, suggested by and edited by BronyStories.

Spike remains trapped in the human world as a talking dog. He's... not quite disappointed by this, because he gets to spend time with a Rarity that doesn't think of him as a kid. As a dog, sure. But a talking one.

Rated mature for canine anatomy, clop, frottage and other such things.

Every Spike has his day

“Hmm... it's a bit shapeless and rather unflattering... but traditions will be as they will be,” Rarity said, holding up the blue graduation robes before her body while she looked at herself in a mirror. The human analogue of the pony everypony should know had grown up well, getting slightly taller, but retaining her bouncy coiffure and her long, elegant limbs. Her skin was still as pale as fresh milk and behind the robe her attire was still as it had been, a loose but comfortable blouse hiding her endowments and a knee-length blue skirt with her trademark triple gems. She even wore her usual high boots, though she also had a pair of sensible flats near her robe. She was in one of the vacant classrooms, preparing for the impending ceremony.

“Oh, it's not unflattering at all. You look good in anything,” Spike commented from the ground. The dragon-turned-dog had not changed much in the time he had been in the human world, growing slightly taller and longer though not by much either way. He still mostly retained his diminutive stature. His tail was all a-wag and he looked up at Rarity with a sigh. “Graduation... and that means...”

“Yes, Spike. The time is coming, and soon. Truth to tell... I am not sure I know what to feel...” Rarity said, a brave smile spreading on her face. She held up the robe again as she remembered the events which prevented Spike from returning to his own dimension.

The Fall Formal was over, the most exciting and strange that had ever happened in the history of Canterlot high. Other than the revelation of the true nature of the school's resident alpha bitch, Sunset Shimmer, and the appearance of real magic, from the appearance of demons and pony-eared girls, the real news was the loss of Twilight Sparkle. She had been there for so short a time, yet she had made so many friends and drawn the whole school together.

“I'm going to miss you girls...” The humanized Twilight said, embracing the human versions of her Equestrian friends. “Take care of Sunset Shimmer. If she has good friends... I think she'll be fine.”

The other girls responded in generally affirmative ways.

“Of course.”

“Darn-tootin'!”

“Certainly.”

“You bet!”

“Thank you. For everything...” Twilight hugged the five girls again and softly sniffed, turning towards the mirrored surface of the statue pedestal which contained the portal to Equestria. “Come on, Spike... time to go.” With that she stepped through and vanished.

Spike started out for the portal, an eager spring in his step. He turned again to regard the assembled collection of people, and found his eyes lingering on Rarity. She was still beautiful, even with a tiny muzzle and odd bodily construction and proportions. Some things transcended dimensions. Rarity would always be beautiful to him. He had fallen for her as a pony, though he was a dragon. Nothing could change though he was a dog and she some strange creature he had never seen before.

The hesitation lasted longer than he had intended. There was a flash of energy that engulfed the statue and the five girls standing around looking at the portal. Their new, pony-eared forms reverted to their normal, colorful human selves. The first thing that happened was Pinkie Pie ran herself into the statue's base, knocking herself silly. Or sillier than usual. The next thing was that all the gathered girls realized that Spike was still sitting in front of the deactivated portal.

“Oh my...” Fluttershy said, leaning down to stroke over his head. “You... you missed the portal. You poor thing. Are you alright?”

Spike seemed to consider the question, then let his tongue hang out and gave a happy, mindless bark.

“Oh dear... it would appear that our fabulous new appearances were not the only things to suffer the loss of the portal,” Rarity said, reaching down to lift up the speechless dog. “Such a shame. Why... save for the body he knew well how to act like a gentleman.”

The crowd that had gathered at Sunset Shimmer's behest began to disperse, to try and make sense out of their chaotic evening. The five girls remained, looking somewhat wistfully to the inactive portal. Once the other people had sufficiently scattered Spike looked around and said, “Hey! Come closer! I need to tell you something.”

There was a general gasp from the assembled quintet, who all pulled in. Pinkie gingerly poked at Spike, feeling up his sides and head. “Wait... you can still talk?”

“Well, yea! I'm a dragon on the other side of the portal and I can talk. I may be a dog on this side but I can still talk because I always could,” Spike said, wiggling around in Rarity's comforting hold.

“Well then why did ya make it look like ya couldn't?” Applejack asked, glaring down at Spike. “Y'all know ah'm no fan-a liars.”

“I know, I know... but I had a good reason!” Spike shouted, clapping his paws over his mouth and looking around conspiratorially. “Do you know what might happen if someone found out I could talk? I went on that 'internet' thing while Twilight was asleep. Those 'researcher' people seem totally scary. Thanks for those fliers, Fluttershy. Twilight would probably be proud of me for learning a big word like 'vivisectioning.'”

“Oh yes, it's really terrible what can happen to animals. You're right to hide a secret like that,” Fluttershy said, gently rubbing Spike's chest and scratching behind his ear. “So... you need a place to stay. I have a lot of animals already but this is important...”

“Oh! Yea... about that...” Spike said, with a sheepish smile, “See, I feel like I know all of you already, since you're like all my friends back in Equestria. And if that rabbit you have is anything like the one I know he'll have me hanging over a pot of boiling oil by the end of a week. Truth to tell... if I could choose I'd rather stay with Rarity. I, um...”

Rarity gave a blushing smile and pressed her nose to Spike's, hugging him a bit tighter. “Well now... I can see you have a great affection for me, and with your intelligent mind you would be far more than a mere pet lumbering about the house. For how long would you need to be housed?”

“According to Princess Luna the portal opens for a few days every thirty moons. I guess the moon works the same over here even if there's no princess moving it,” Spike said, tapping on his chin.

“Thirty moons? That's... way over two years!” Rainbow cried.

“Ah get enough of that from mah brother. Don't you get all mathematical on us, Rainbow,” Applejack said, casually tweaking Dash's nose.

“Two years... it would seem you shall be here until graduation time. It may be a long time but I have a feeling that you will remain, ever, a perfect gentleman,” Rarity said, giving Spike a kiss on the nose.

Spike wagged his tail wildly and looked at Rarity with a loving expression.

Rarity laid the robe aside and strolled over to Spike. She reached down to the dog and scratched him slowly behind an ear with her long, beautifully manicured nails, her other hand coming up to tenderly tickle him under the chin. “You have certainly been a very loyal friend, Spike. As I said that night, you have ever been a proper gentleman.”

One of Spike's rear legs kicked in reflex, his tongue hanging out and eyes slightly rolled up. The scratching was in just the right areas, but his reaction was from Rarity speaking of him so highly. The pony Rarity had said such about him, but typically had more distance between them. “Aww... it's just polite, Rarity. I know that you like it when I'm a good boy.”

“Indeed, and you ever are, even when you are not,” Rarity said with a wink. She took a seat on one of the stray rolling chairs and slowly started to remove one of her boots.

As though on command Spike raced over to Rarity's other leg, leaping onto her boot and vigorously humping the smooth, vinyl surface. His slightly-larger size put his head well above her knee, and over her skirt, in some perverse version of 'gentlemanly' action. His forelegs hooked around the boot and he thrust his haunches madly, head thrown back and moans pouring out of his mouth. “And to think I used to hate dogs...” he muttered.

“Oh dear, you are an incorrigible little gent, aren't you?” Rarity cooed, gingerly scratching behind Spike's ears after removing her un-molested boot. She was completely unperturbed as her fabulous footwear was rather shamelessly assaulted by her canine friend. “Can you not wait until I remove them before you begin your hormonal display?”

“Heh, sorry...” Spike said, appearing rather chastised by the gentle rebuke. He humped on, however, even as Rarity slowly and carefully slid her leg out of the tall boot. “I can't help it. I mean, the you I knew in Equestria made clothes too but she didn't wear them all the time. No one did. And you have so many more kinds, like these things. She had boots too but nothing like these! Plus, well...” He suddenly blushed and turned his head away, ashamed, though not ceasing his action. His puppy pecker had already partially emerged form his concealing sheath and was slowly grinding against the smooth and polished surface, while his testes bounced lightly with each thrust of his hips.

“Oh, becoming a bit retiring now? How unusual, you are usually so bold and forward,” Rarity noted, stretching out on the chair and wiggling her porcelain-pale toes in their new freedom. She rather playfully reached out and stroked the wriggling digits against Spike's hunching back, using her big toes to focus her stroking down his active spine.

Spike shivered and let out a long, low moan as he was so lovingly stroked. He looked back at Rarity with a blush still evident on his muzzle. “Well, umm... these things get to hug your legs all day. I envy them. I secretly envy all your clothes just because, thanks to all these weird human rules you always have to have them on you. They're so lucky...”

Rarity clicked her tongue and shook her head, tickling Spike's sides with her toes. “Oh my silly canine. You need not envy my clothing. After all, you seem to have no trouble placing yourself upon me at every opportunity.”

“N-no!' Spike said quickly, slowly letting himself down from the boot, so as not to interrupt the tickling.

“Really now? Well, what of your actions at poolside during the glorious summer months?” Rarity said with a teasing tone.

Rarity was somewhat more privileged than her friends, even and above the minimum level that allowed them all to live in an area with a prestigious high school and general high standards of living. Her own living situation involved lakefront property, a three-story home and gates to control access.

Even with her own private portion of lake, along with paddle boats and a small touring boat with a sun deck Rarity preferred to spend her summers by the side of the pool up the hill from the lake, which also had a beautiful redwood deck for lounging. Both lake and pool made for wonderful swimming parties with her friends.

She lay out in the sun, alone, enjoying a day off from fashion focus. She did love choosing attire for her friends and the sense of joyous camaraderie that had been the norm since the events of the Fall Formal, but occasionally all the ladies needed time to themselves. Even Sunset Shimmer, who savored having friends, occasionally spent time on her own, to develop and better herself. Rarity was also trying to tan, despite the fact that her skin always seemed to remain perfect alabaster. It was simultaneously infuriating and fascinating.

Her attire for that day was the standard for her summer endeavors. Since developing her more womanly figure, rather early thanks to good fortune and a proper diet, she had always selected various two-piece suits, typically with her favored triplet of blue gems. Her selection that day was a green-and-purple ensemble, cut a bit smaller than her usual, more merely covering than cupping her swells of milky flesh, the rear portion of the bottoms pulling closer to the size of a thong than she had considered previously. Her sunglasses were silver-framed, with the gem trio on the sides.

As she lay there on her deck chair and towel, slathered in oil, eyes closed behind the sunglasses and face modestly shaded by her large, floppy sunhat she had the sensation of someone near her. The opening of one eye showed nothing and set her slim shoulders to shrugging. The feeling did not go away, and she had the distinct impression of a soft sound somewhere by the base of her chair. The proof of a presence came when a wet something slid across the sole of one foot. “Oh dear! What in the world?”

“Oops, heh, sorry,” Spike said. He was sitting at the foot of her deck chair and was looking slightly guilty up at Rarity. “I wanted to tell you I was here and, well, I think I might be going native. Having a dog body makes it a little too easy to act like one.”

Rarity placed a hand over her heart and sighed, dropping a friendly smile after a few breaths. “It is perfectly understandable my little Spikey-wikey. It gives the proper appearance should my parents be in earshot or should my sister and her friends be lurking about. Oh not that I mistrust them, you understand, but young minds are hardly secure minds. Idle talk could spread after all.”

“Right! And I'd still rather keep my guts on the inside,” Spike said, poking at his belly and giving a soft giggle. “So, are you going swimming? Now that I'm not a dragon heat seems to bother me way more than it probably should.”

“I had not planned as such,” Rarity confessed, “I thought I would attempt to tan away this mysterious paleness, as I ever do. It is my quixotic endeavor, but I relish it. It may work one day.”

“Well, if I may be so bold, I have to say... I like that pale skin of yours,” Spike said, with a hint of a blush.

Rarity quirked a brow and smirked slightly. “Oh? Because it reminds you of the pony you recall from your home?”

“N-no! Yes. But also... it just suits you...” Spike said, slowly stepping up to nuzzle at one of Rarity's long, graceful legs. His tongue slowly licked at the smooth, unblemished milk-white skin, over the calf and back of the knee, ending with his head resting against her thigh.

The lick brought forth a shiver from Rarity, as well as a soft, pleased sigh. She reached down and scratched at the side of his neck. “You are very kind to say so. Were you so comforting to my equine counterpart?”

“I tried to say nice things a lot,” Spike noted, slowly wrapping his forelegs around Rarity's leg as it slid off of the deck chair, “But I never really got too forward. I wanted her to feel good, so she'd know how I felt.”

“Always a gentleman,” Rarity said, pressing her foot up to lightly lift Spike up and then let him back down again.

“It's only right, m'lady,” Spike whispered, his eyes drifting closed as he hugged that smooth, perfect limb. By instinct, the consequence of his dog form, his hips gave a sudden hunch, grinding the purple tube of his sheath against the skin slick with oil. The warmth, the silky texture, the sheer closeness and thoughts of both Rarities drifting through his mind made his body relax its usual tight control on his sexuality. It was only natural. Dog paws were notoriously bad at grasping anything, and he was disinterested in oral self-stimulation. Only through vigorous grinding and frottage could he sate his ever-burning lust.

His canine organ emerged from the sheath, a little at a time. Had anyone been there to observed it would have looked like nothing so much as a rich, deep red column of lipstick sliding from the tube, pointed tip included. The more the sensitive flesh ground against Rarity's leg the more his muscles twitched and the more that he felt the pleasure rise, sending the long, canine tool up with it.

Rarity, for her part, did not have a significant reaction. Beyond some initial shock and a light shake of her leg when the humping began she actually did very little. She allowed her leg to slide off the side of the deck chair, and rested back against it. Her sunglasses-covered eyes showed nothing about her emotion, and her mouth was set in a neutral position. She may have, during the increasingly-desperate thrusting, moved her foot up to cup and cradle Spike's tested but it may have merely been a twitch from the feeling of his dewclaws sliding against her sensitive skin, which left slight lines on the milky surface.

The lotioned, oiled and well-pampered skin of Rarity's leg was greater than anything Spike could have ever imagined. It was better than his scaly hand had been, even though he conditioned and oiled and did everything to soften his tough scales. It was even better than all the bits of soft material he had surreptitiously 'borrowed' from Carousel Boutique, like taffeta, satin, velour and velvet. The top portion of his dog rod was rubbed against the silken fur of his body, kept soft by regular care and attention from Rarity and high-end canine products, while the lower was ground against the skin, which was as smooth as the porcelain it resembled.

His entire organ had fully emerged from the protective sheath, tapered point leading to the bulging middle portion that tapered just slightly near the base where is swelled out into the truly unique knot just outside of the pushed-down covering. He ground the whole, alien surface of his dick against Rarity's unmoving leg, his lust-fogged mind scarcely aware of what was pleasing him.

Thin, watery precum spit fitfully over Rarity's shin and calf, as Spike was latched onto the leg slightly to the side. His dewclaws continued to subtly scratch and scrape along the tender flesh of the human girl's leg, unable to find purchase, and thus do real damage, thanks to the youthful tautness and the application of tanning oil which kept everything moving slickly along. His haunches thrust and drove his pumping pecker firmly against the limb, grinding his knot hard against it while his balls bounced off of the skin, occasionally cradled by a twitch from Rarity's foot.

He drooled lightly, tongue out and laying on Rarity's knee, his eyes mostly glazed over as he rocketed rapidly towards climax. Had be been more aware of himself he likely would have been ashamed of his sudden hormonal action and the form it took. But his mind was only tell him to rut, hard, fast and steady as long as he had the silken flesh to use as his personal plaything.

His orgasm seized him much more sharply than it had before in Equestria, likely due to the new parts of his anatomy and the glorious new feeling of real, living flesh against his masturbating organ. His knot bulged significantly as the climax struck him, and his hips pushed forward hard, practically jamming his tip against his own chest. The cum that squirted out in abundance was hot, thin and cloudy, sliding down the oiled skin to splatter on the wood of the deck.

Spike nursed his extended orgasm with presses of his knot against the firm surface of Rarity's shin, a pleasant jolt of delight running through his new dog nerves, making him jerk his hips again and sent out another light squirt of ejaculate. Eventually, though, he had run his course and sighed, shaking his head a touch and unhooking his legs from Rarity. “Oh man... that was amazing.”

Rarity casually removed her sunglasses and drew off her hat with a toss of her head to let her bouncy curls spring and sway around her head. She looked down at her leg, noting the reddish scratches and the lingering goo flowing down. “It wold appear I will need high boots for a time...” She then casually reached down to scratch Spike behind the ears. “But now, I do believe we both will need a long swim in the pool. It will be most refreshing.”

Spike leaned into the scratching, a blush burning on his cheeks. “O-okay... sounds good to me...” He leaped into the pool with a tremendous woop, Rarity following much more sedately down the stairs, after using her towel to wipe up the puddle on the deck.

Rarity was in front of the mirror again, unbuttoning her blouse and humming softly as her frilly, filigreed bra was exposed. Her smile pulled larger as she saw Spike in the mirror with his paws over his eyes. “What has inspired this touch of prudishness?”

“Oh, habit I guess...” Spike said, slowly dropping his paws from his eyes. “I've been here for a while. Now clothes look really natural on you, and I'm sorta understanding maybe I shouldn't look when you're getting naked.” He trotted over to the mirror and smiled at the filly bra. “But I still don't understand why humans wear stuff that no one's going to see.”

“Silly boy, I suppose no matter the species males will never understand,” Rarity said with a light giggle, unhooking the straps and sliding the bra down. Her heavy, matured breasts bounced out, high, taut and properly globular. She was completely untouched by the scalpel, the recipient of nature's gracious gifts. She dropped the bra onto Spike's head and laughed as one cup settled onto his head like an odd, frilly hat. “They are for us to express artistry... and to be seen by the special, those we deign to allow to see them.”

Spike got heart-eyed over the lingerie falling onto him, hugging the other cup against his chest, and surreptitiously rubbing it against his partial erection. “Oh, that's neat! It's truly an honor to see this. But, why did you leave off that thing that matches, the one for your legs?”

“Naughty Spike,” Raritly clucked, putting on a faux-upset moue as she wagged a finger at Spike. “I told you that it is very rude for a gentleman to look under a lady's skirt, whatever his stature may be.”

“Hard not to when you all wear short ones and liked crowding around me. I just naturally look up to see your beautiful face,” Spike's tail had been set to wagging and he gave a large, sincere smile to the topless Rarity.

“I shall believe you... you are so often in earnest. You are honest, in word and in body. I do not know how it was with your Rarity but you never seem to try to hide any thing from me,” Rarity noted, sliding down her skirt to reveal a pert and perky butt that was gently rounded and smooth as could be. “Were you really so honest?”

“I tried to be as honest as I could be, while... hiding a lot of my feelings,” Spike admitted, pawing lightly at the ground. “I did things but said other things... and even when I was close to her I was never as... 'honest' as I was with you. Like last winter...”

Rarity greatly enjoyed the amenities of her home in winter as well as summer. The lake would freeze over, leading to a perfect skating surface, while her mother had made certain the house had a wood-paneled European sauna with authentic Nordic volcanic rocks to take the edge off of any chill that could piece the double-paned windows, heavy insulation, floor heaters and central furnace. The house was, naturally, a popular hangout for the ladies of Canterlot High.

Though there was a distinct chill outside, along with a more-than-light fall of snow which precluded visitation by the other girls, Rarity was not partaking in her usual sauna session. She had sequestered herself in her room, with the door locked, in order to keep Sweetie Belle from inserting herself into her day, though she knew Sweetie was likely with her friends skating, making snow creations or being towed about by the butch one on a toboggan drawn by some sort of motorized conveyance.

She was not, however, entirely alone. Spike was, as ever, with her. There was a pop album on the stereo, alternately filling the room with catchy, bouncy tunes and slower, more tender ballads. The two were comfortable settled on Rarity's large canopy bed, wrapped in a Canterlot Wondercolts print fleece throw blanket, Rarity's head covered as though in a hood, while Spike just barely poked his head out of the opening.

“Now this is the life...” Spike sighed, wiggling his furry body against Rarity's side. He was hugging against her side while his head mostly rested against her chest and neck.

“Indeed. Hardly a 'dog's life' as they say,” Rarity giggled, leaning her head down to kiss one of Spike's ears. “Your situation would be the envy of many in the world.”

“I'd envy me if I was still back in Equestria and could see me now,” Spike said, gently lapping at Rarity's neck.

“Mm, I hardly believe your life was much different. It would certainly not be worse or otherwise hurtful,” Rarity noted, one hand stroking down Spike's back and softly cradling his bottom.

The blanket moved as Spike's tail was set to wagging and he gave a happy yap. “Oh it was great! I told you about how I lived with Twilight in the library, and we always had a lot of fun in Ponyville... when I wasn't too busy cleaning and organizing the place. But Owlowicious helped, and I had a lot of free time.”

“You were certainly a hard-working fellow, my dear Spike,” Rarity said, patting his bottom gently. She looked at a portion of her room which was filled with canine paraphernalia, including an expensive dog bed and silver dog bowls. “I believe I see that things are much different here.”

Spike looked over to where Rarity's attention had drifted and coughed softly. “It's different but not bad!” His tail wagged about faster, and he pressed more firmly against Rarity's side, and her attire. She was casually attired, wearing only a pink silk slip, which freely slid against her smooth body as Spike's slightly-rough fur pulled and dragged it around. “Not bad at all...”

“Unique, I would say, certainly in your relationship to the rest of the world, to us, and to physicality...” Rarity whispered, feeling the slight point of Spike's organ nudging the side of her silk-covered breast. She took ginger hold of one haunch, feeling the muscle flex and twitch as his instinctual drives set him to humping. “I mean... my form is very different from the pony body you know well.”

“Different's not bad,” Spike muttered softly, rising up slightly against Rarity's body. His toes touched the bed and he stretched his body as he thrust his emerging organ against the silk slip and the soft swell beneath. His unrestrained sexuality had lowered his threshold for arousal, meaning his while pecker, pointed tip to knot, had risen to full firmness and was grinding along the side of Rarity's breast, spitting precum freely.

“No, it certainly is not bad. I come to realize this more and more as time goes by...” Rarity whispered, one hand drawing the blanket tighter around the two of them, keeping all activity from view and leaving the only evidence the suggestive and rhythmic flexing motions seen against the surface of the taut blanket. Her other hand remained on Spike's haunch, squeezing when he flexed into a thrust... or perhaps her squeezing inspired each thrust. It was hard to tell as lust took over the Spike's mind.

There was a certain familiarity to the feel of a smooth piece of silk sliding over his desperate erection, but all similarity ended there. He had developed a new appreciation for the contours and construction of his dog dick. There were parts to it not on his draconic member, especially the knot. Pre-orgasmic squeezing produced a nice sensation, while post-orgasmic squeezing practically set off another climax. He ground the knot rather significantly against Rarity's body and let out soft, desperate whimpers as he was rewarded with light jolts of pleasure.

The desperate and unplanned frottage proceeded swiftly, especially as Spike's tip more often than not either probed Rarity's deliciously soft breast or slipped beneath it, each motion made smooth and warm by the slip and the blanket around them both. He was taken by surprise by his peak, jabbing forward one more time and unloading heavy splatters of seed across Rarity's chest, on the slip and on the bare portion, her cleavage and above.

As ever he rewarded himself with the extra pleasure of squeezing his knot against Rarity before his slumped, spent and delighted, against her side. A quick lick at her neck and he gave her a blush, looking rather guilty. “I'm... I'm sorry, Rarity.”

Rarity moved the hand from his haunch to under his chin, turning his head to face her. She planted a soft kiss on his nose and rested her face against his, pulling him into a tight hug. “Don't fret, my little Spikey-wikey. You were only being honest. And besides... given this cold weather I can say, at least, it is warm...”

Spike had mounted Rarity's leg again, but she was not resisting, nor was she neutral on the matter. She was watching the masturbatory effort with great interest and no small amount of lust, one dainty finger actually down, sliding around Spike's uniquely-shaped tip. “It really does look like lipstick... though you are seldom content to simply rub it on my lips...”

“I was fine with it,” Spike said, adjusting his grip a few times as he slid his organ side to side, at the direction of the finger against his member. “You wanted to taste. And then, you wanted more.”

“I did, and I accept it was my doing,” Rarity said firmly, moving her hand away and leaning back in her rolling chair. “Now then... I have a present for you. Something that you have needed for a while, as my legs and scuffed boots can attest.”

“Oh? What is it?” Spike asked, his hips dropping a gear.

Rarity reached aside into her bag, pulling out what looked like two boots, composed mostly of purple vinyl with a white inner cloth surface that rose out of the openings. They could be laced up along the back, and featured, as decoration, a small, chubby dragon. “These will serve us both well, I think... Come here and let me put them on.”

“No wonder you wanted my measurements last month!” Spike cried, hopping off of Rarity's leg and approaching her offering hands. “This is so nice... and they'll probably help with the scratching, even more than nail trimming,” He noted, blushing a bit as they were gently slipped onto his paws and up his legs before being securely laced up.

“It is necessary, and kind. You are deserving of such a gift, particularly on this day of all days,” Rarity said, slowly directing Spike onto his side and then to his back. “Let us begin...”

Spike's tail was going a mile a minute, his face almost scrunched up in anticipation. He felt a cool flow over his organ, which was resting against his belly. The warm scent of lavender filled the air as the lubricant purchased on Rarity's eighteenth birthday flowed over his pulsing rod. The viscous fluid ran in little rivulets over the side of his length and especially over the bulbous swell of his knot.

That knot, after saturation, was the recipient of a good, sustained bit of squeezing from both sides. Rarity was leaning back in her chair after capping the lubricant, using her dainty feet to press in on both sides, toes rubbing and tapping along the rounded contours of the knot. The sensation was unique for both, Spike greatly pleased by the smooth, soft touch while Rarity had to deal with the little tickles from the sliding and pressing.

“It would be an utter waste to keep my lovely feet so perfect and not use them,” Rarity said, softly cupping her breasts, rubbing her fingers along the lower swells, just lightly teasing her aureolae. The graze of her acrylic nails across the slightly-erect flesh drew light gasps and gentle moans, adding to the pleasure of her pedal manipulation of Spike's bulbous base. “The pumice, the lotion, the baths, even that trip to the spa with the fish that exfoliated...”

“All worth it!” Spike yapped, thrusting up against the slowly-squeezing and gently-stroking feet, though he really wanted to just let Rarity work at her own pace. “Oh that's so good... the other Rarity didn't have anything like this...” He mumbled, panting rather heavily and starting to lose his focus.

“Indeed. This is why I thought this occasion deserved such novelty,” Rarity cooed, gasping as her thumbs flicked over her stiffened nipples. She slid both feet up Spike's throbbing pole, graceful arches cradling his rather fat doghood. Her slid all the way up to the top, letting her toes flex down and tease the pointed tip. She massaged the precum-spitting top with her big toes, before capturing the organ between the big and second toe, sliding slowly up and down a few times. She swapped feet after the slow massage, the overall effect working the lavender-scented lubricant over every inch of Spike's tool.

Spike was laying out, tongue flopped out, eyes practically rolled up into his head when the warm, silken pressure moved away from his maleness. His head pulled up after a moment of shaking to clear out the lustful fog. He saw rarity wiping her feet with a towel and going down to all fours, lowering her rear end and rising up on her arms, to stretch herself beautifully. “Wow... I can't believe...”

“It will happen,” Rarity said with a smile, making a motion with her head to bring Spike over. “I promised you... your time is growing ever shorter, the portal will open once more and your home will be available to you. And I suspect you will leave.”

Spike rubbed his head against Rarity's chest, kissing and licking over one hanging breast. “I know you promised, and we have to get to it before the portal opens again but... why did you agree to it in the first place?”

“I told you, but I think you cannot believe it,” Rarity said, pulling Spike up to one breast and moaning as his tongue lapped against her erect nipple, his mouth eventually clamping around it and starting to suckle. “Ah... I have promised to give myself to you on graduation day because I wish to thank you for your loyalty, your kindness, your gentlemanly nature, and... because, over these few years I have honestly fallen in love with you.”

There was a moment of blushing from both, with Spike pulling his lips away from the nipple he had been suckling. The two did not need to speak to bring themselves together into a hot, passionate kiss, Rarity grabbing Spike's head, Spike placing his booted forepaws on her shoulders. The two moaned deeply, their kiss involving lips alone for just a moment, both of their tongues dipping into each other's mouths. Rarity's tongue was deliberate in its motions, tracing over Spike's pointed teeth, caressing down his tongue, along his cheeks and even to the entrance to his throat. Spike, however, was far more chaotic. His tongue attacked the inside of Rarity's mouth in a blatantly canine manner, licking in a careless, sloppy manner. Drool passed freely between them, the seal between their mouths breaking as they moved their heads around and let out moans of pure pleasure. Not all of the saliva could be Spike's, they both contributed to the splattering on the floor of the classroom.

They parted after a long moment, lips popping apart and letting loud gasps emerge from both sets of lungs. Both of them panted heavily, eyes fogged and unfocused, smiles on their lips, which were still connected with shimmering, quivering strands of saliva which finally snapped as their breaths huffed out. Rarity licked the drool from her lips and playfully wiped a dab of it from Spike's lips, placing it on his lips, which prompted him to kiss her finger. “I think... we are both ready.”

“Yea...” Spike sighed, shivering in anticipation as he looked into Rarity's eyes. “I can't wait.”

“And you shan't, darling,” Rarity said. With a final caress of his head she returned to her place on her hands and knees, gracefully turning her body, with a toss of her head to make her curls hover around her like a lavender halo, enhancing the scent of the lubricant that hung in the air. Her back arched, knees stepping out to lower her rear while simultaneously spreading her thighs. Her pert butt pushed up and out while she exposed her lips of her sex. She was as smooth and milky as everywhere else, save for the well-maintained diamond of dense amaranthine hair sculpted just above the hood of her clit. She was just slightly spread, offering a deliciously teasing peek of the flushed pinkness-bordering-on-red within.

Despite his previous anticipation and desire, Spike's approach to Rarity's exposed sex was slow, almost reverent. His booted paws lightly pressed against her knees and slid up, against her inner thighs, spreading her just a bit more while he leaned in to sniff at her vagina. After a few curious sniffs that took in the scent of powder he stuck out his tongue and slowly ran it along from clit to perineum.

Aside from the taste of powder there was a slight tang, vaguely metallic and somewhat musky, especially over the inner flesh that his tongue rubbed against. His tongue swiped through again, much more focused between the outer lips and ending with a harder grind and press against the clit, making Rarity moan out loudly and slide down onto her forearms, palms pressed to the ground. “Goodness... are you certain you, too, are inexperienced?”

“Umm, I'm just guessing... I need to know when I do something right...” Spike noted, licking rapidly just between Rarity's labia, twisting his tongue around to sort of 'drill' his slippery tongue into the passage he found within. The trembling of the walls and the vocalizations from Rarity made him all the more confident in his techniques. A few more licks turned into an experimental pursing of his lips, settling them around her clit and suckling, as he had on her nipple.

“Right! Very right!” Rarity called, somewhat breathlessly, pushing herself up and back slightly to grind her rear against Spike's face. She trembled from top to bottom, a high, keening whine passing through her lips.

The sharp sound made Spike twitch, his mouth pulling away from Rarity's button. “Ow! Wow that sucked... no wonder those Diamond Dogs let Rarity go when she started whining. Having sensitive ears kind of sucks,” Spike said, going back to softly licking at Rarity's opening, noting how much wetter it had become.

“You so often speak of her and how you did so much for her, from a daring quest underground to giving up a gem you desired,” Rarity whispered, the tender licking stoking her fires without sending great shocks through her. “Why did you never do this? It is clear you had a great love for her, and that she knew this. Why could you not be her lover?”

Spike was still and quiet for a bit, scraping one booted foot along the floor as he considered his answer. “I used to blame all kinds of things, from evil villains to... her at one point. But now I know it was no one's fault.” He leaped up suddenly, slippery front grinding against the tops of Rarity's buns while his slicked-up and erect flesh slapped between her white cheeks, casually hotdogging her. “It was just the way things worked out...”

Rarity began to huff and pants, rocking forward and back slowly. The position of Spike's member between her cheeks had placed his knot against her teased and dripping sex, which ground and dug in between her lips, as though giving her some show of what was to come. “Wh-what do you mean? Surely there was something that could have been done?”

Spike went on his his fitful humps and grinds, treating Rarity's asscheeks as he had her leg or her side. “She met me as an assistant to Twilight, and thought I was just some kid, too young and immature to be serious. We never got past that because we couldn't get together any other way. But you and me... we started off even, and grew together into this. We had time to get here,” He said, slowly dropping his posture, teasing his pointed along between Rarity's cheeks, until it was settled against the flushed pinkness of her sex.

Rarity lifted her head resolutely and took in a long, cleansing breath, releasing it with a slight shiver. “You will find no barrier to you, physical or mental. But you, as I said, will be my first...”

Spike only nodded his head, the horny canine treating the encounter with the significant reverence that it demanded. He was fighting the war against his body and was, for the moment, winning. He carefully made some adjustments to his posture, slid his chest up and over the top curves of Rarity's ass and used his well-trained hips to thrust forward, driving the point of his doggie prick into Rarity's warmth.

As Rarity had said there was no barrier to stop Spike's driving organ, not that his pointed tip would have had any trouble puncturing through any such thing. She had taken that away to avoid the potential of leaving a crimson trace that would give them away. With nothing halting him or harming her Spike was able to drive himself down a good distance with just a few hard thrusts. He had to stop once the depth had pushed his upper body far enough that his forelegs slipped around Rarity's narrow waist, his boots ensuring that she felt only the smooth slide of polished vinyl and not the scratch of his dewclaws.

Both of them had to moderate their responses, vocalizing a certain amount but not too much, just on the off chance anyone could hear and might notice the doors were locked. Rarity's head fell form its high position, her cascading rings of hair forming a sort of private bower for herself, slightly-amplifying her restrained moans and whines. She did her best to remain rock solid, giving Spike a proper target for his lustful adoration.

Spike's legs hooked on around the top of Rarity's hips, giving him the proper hold to pull himself into hard, deep thrusts. His hips were impacting on her butt with each thrust, cushioned by his fur, with the energy reduced by the fact that he couldn't draw back very far. Rarity had risen up a little, leaving his hind paws just barely able to touch the ground. He had to rely on his hips for the primary pull-back and thrust duties, and he was not quite robust in that area. He was still buried deep in her, and was having her as he had always desired. Even in the body of a dog, even if it was a human, it was Rarity, and he was having her, with her adoration.

It was real pleasure running through his whole body, greater and more complete than the many forms of masturbation that he had performed in the course of his romantic misadventures. Spike's hips worked hard, his toes using all the purchase they could get against the ground, making him leap into his thrusts, mashing his knot against Rarity, and also getting his balls to tap and slap on her thighs.

There was more to the feel of penetration than what she had experienced when she used that 'massage tool' to handle her hymen and train her passage for their coupling. In the back of her mind Rarity was amused by the fact that she had been masturbating almost as much as he had been, and possibly enjoying it just as much. She had thought there was pleasure in pampering and fashion, but carnal pleasure was far more. It was magnificent and felt to only be getting better as the deep thrusts pressed the large knot against her, promising, or threatening, to give her all the penetration she could handle and more.

She was becoming wanton as the warm sensation of delight crawled through her body, like an electrical tingling radiating from her sex. The heavy slaps, wet from the impact of knot or drier when it was hips meeting her hind end, rang in her ears and drew out pleasured coos between the lusty groans. “Oh Spike! Spike it is glorious! Tell me! Tell me how it is for you, darling!”

“It's good... feels... nice...” His mind was slipping away, his lust suddenly winning the war against his brain. It was a distressingly familiar sensation, very much like the loss of his rational mind when he was gripped by greed. Lust and greed... they took him over, but there was somehow more to the lust, because he was not taking, he was giving, he was sharing his lust with Rarity. That made it fine. He could slip into the mindless oblivion, forget everything but the pleasure of rutting his lady love. His tongue fell out of his open mouth, while his eyes grew more and more glazed.

“How quaint!' Rarity squeaked, believing she was as foggy-headed as Spike. Indeed, her usual clear mind was heavy, as though shrouded in a cloth of the feeling, the many sensations hitting her at once, from the delightful stretch and deep plunging into her heated and squeezing passage, to the tickles of oily fur sliding and grinding against the bare skin of her behind, to the very unique sensation of warmth, his precum splattering over her vaginal walls. Surely his lustful experience could not have been much different from hers. “Deep as you can, darling! Deep, hard and all the other filthy words we learned together!” When no reply was forthcoming some part of her sensible mind realized it. “Spike?” She queried.

Spike was long gone. Whatever sensible, civilized part in his mind remained was tucked deep inside of his carnal desires, the animalistic urges holding tight and leaving him in a state no different than any other dog. He drooled freely onto Rarity's back and let out pleasured yaps each time his pumping puppy pecker got a good squeeze from the trembling walls that surrounded it.

With his mind nothing more than that of a dumb animal he could not even tell Rarity was starting to sound a bit concerned, and that her fear was making her pussy clench down tighter and with greater regularity. “Please... please Spike... say something... say something please!” The mashing knot was the final straw. What had been a wonderful bit of exotica when Spike was talking and laughing became only an indication of his true nature. A dog. A dog was on her back, was mating with her, drooling over her back. Her first time was with some mindless animal.

The imperative from his body was clear. Knot. Tie. Merge and unload! He was no longer drawing back and thrusting up to smack fur to flesh. He was forcing his knot against her, grinding downward against her clit every few attempts but mostly just attempting to get it in. He whined and strengthened his grip, pulling on her sides to fulfill his body's cries.

Rarity was resisting the knot, the strange, animal anatomy trying to force itself into her human body. She was clenched too tight to allow such a violation. By Spike. It was Spike. The thought came through, pressing aside the clitoral stimulation and the socialized disdain for such animal mating. He wasn't a mindless beast. He was a witty and urbane soul, a gentleman that had been a true friend for years. They had pledged themselves to one another. “My Spikey-wikey...” She said, loud enough to be heard over his whines and yips. “I know you are in there. I know you are still the same loving, sweet Spike. No matter the shape... what matters is I love you and I give you my self. Completely...”

Spike's knot slowly slipped into Rarity's lips, her muscles unclenching enough to give him the freedom to grind in the bulbous bit of flesh. Past the thickest portion the knot slipped in with almost an audible 'pop' and a very audible howl of delight. That howl doubled as an orgasmic cue. He came, hard and strong, cock unloading heavy ropes of dog cream inside of Rarity while his knot swelled, locking him to her.

The swelling stretch was the last bit of stimulation that she needed to push her over the edge following the sensation of Spike's seed splattering across the walls of her vagina. She threw her head back and gave a cry that went along with Spike's orgasmic howl. She recovered from her climax first, head hanging and a smile on her face, sweat just lightly beaded on her forehead. “Darling... have you recovered yourself?”

Spike shook his head once the pleasure of his orgasm had started to fade. The bestial lust drained away with each shot of semen, leaving him pleasured but confused. “Rarity... that was wonderful. I'm so glad we got to share this, m'lady...”

“And I, as well, relish what has been done. I love you, darling,” Rarity said, slowly lowering her body fully to the ground with a soft sigh. “Sadly, this pleasure will not last.”

Spike's head shot up, turned to look at Rarity with some concern. “What? What do you mean?”

Rarity pointed languidly to the clock on the wall. “We arrived early, to get privacy for our coupling, before the graduation. But the graduation must come.”

“Oh, right,” Spike said, settling down on Rarity's butt, head resting at the small of her back. “Well... we know how long it takes for this to go down.”

“Quite unfortunately...” Rarity said, “With the cleanup, the makeup, the dressing, I am quite afraid that we both must endure a bit of hurt, in order to make this work. You will need to turn yourself around, as we saw in the diagrams and... we both must pull.”

“But Rarity... that's gonna hurt you. A lot,” Spike said, with great concern.

“Indeed, Darling, and you as well. I am terribly sorry to put you through such but we no longer have a choice. We came to this point, because we wished it. Now let us take responsibility for all that must happen,” Rarity said, placing her hands on the ground and looking resolutely forward.

There was still a great deal of uncertainty on Spike's face, but he pushed himself off of Rarity's bottom and swung a leg up and around, turning rear-to-rear with her. After a moment of preparation he surged forward, using the traction provided by his boots to pull on his knotted rod. The pain was immediate, for both of them, whines and grunts emerging from both as they pulled hard.

Rarity's flesh was trying to release the bulge of flesh, but the attempted removal involved removal of something bigger than what had just barely made it in. It was no easy feat for a virgin. But she upheld her end of the pull, crawling on her hands and knees with as much force as Spike.

The two exerting force finally did what they wanted, with a sharp cry and a wet squelch Rarity fell forward onto her naked breasts, while Spike took an end-over-end tumble. Rarity's raised hind end showed the slight gape of her passage. Slight flexes of her muscles attempted to get it back to a prior shape, but her lips were simply unable to get back to shape by sheer will.

“Oh Rarity...” Spike said, in a shamed whisper. He was responsible for that. His completely inhuman anatomy had done it to her. “I'm sorry.”

“There is no need for regrets, my Spikey-wikey,” Rarity said, giving Spike a loving smile. “What we did was beautiful. We will have greater success when we may take all the time we desire. But for now... I do hate to impose upon you but if you could please tidy up just a bit while I touch up my face and bring my hair under control...”

“Yes, ma'am!” Spike said, cheerfully, immediately dashing to the bag Rarity had brought, picking up a towel in his teeth and getting to cleaning.

The graduation proceeded without a hitch. The girls all sat together, and cooed over both Rarity's beautiful coiffure and perfect makeup, and Spike, who had been given a little tuxedo jacket, a top hat and, for extra cuteness, a mustache. The two shared a wink over what the manly accessory meant and why Rarity sat very gingerly. When her name was called Rarity had a particular gait, sashaying up to the podium completely nude under her robe, with dog semen slowly sliding along her thighs.

Epilogue

The Ponyville Six, along with Princesses Celestia, Luna and Cadence, were all gathered around the portal mirror, and had been since the declaration that the time had come. They could not be certain when Spike would come through the portal, or even if he could. There were endless numbers of unknowns, and it would have been too risky to send Twilight through once more.

“Oh I hope he's been alright...” Twilight said, pacing in front of the mirror. She had been been rather tirelessly pacing for several hours.

“If there is one certainty about Spike it is that he is quite resourceful,” Rarity said, resting on her fainting couch. “I am quite certain he found a way to survive and thrive.”

“He has always prove himself to be resilient,” Princess Celestia said with a bright tone, gently stopping Twilight by placing a hoof on her shoulder. “If there is a problem, if, and the portal threatens to close without any sign of him you may go in to question those you still know concerning him.”

“Thank you Princess,” Twilight said, looking to the mirror again. “I'm just... I'm so worried about him...”

“We all are. We've really missed him,” Fluttershy said, eyes going wide as she saw the mirror glow. “Look!”

All eyes turned to regard the mirror as the surface rippled and flashed, Spike appearing out of the silvered surface. He looked down at his hands and back at his tail, seemingly a little lost in his own body. After a moment he noticed all the others around him. “Uh... hi there!”

The moment of stunned stillness broke as the Ponyville mares rushed forward at once to embrace Spike tightly, cooing and offering cheerful comments.

“Oh Spike... I've missed you so much. Things just haven't been the same without you,” Twilight said, openly weeping.

“We have all missed you... in various ways,” Rarity said, delicately, gently rubbing the top of Spike's head. She seemed a bit surprised that he reacted by sticking out his tongue and panting.

“Good ta see ya again, we was startin' ta get a mite worried,” Applejack said.

“Awww...” Spike stuck a finger against a fang and smiled, “Thanks girls! I really missed you too. It wasn't too bad, but I felt bad about not getting back.”

“Now you have returned, and it seems you have fared well. We had feared you would be in distress,” Princess Luna said.

“Nope! The girls on the other side helped out. Well, mostly Rarity...” Spike sighed, looking rather dreamy.

“Ah, yes, Twilight did say we had reasonable facsimiles in this other world,” Rarity huffed, bouncing her hair, “Though from what I could gather given the description of their general construction I doubt very much this equivalent was very similar.”

“There are a lot of similarities. And... some differences...” Spike said, a deep blush burning on his cheeks.

“I'm sure you're happy to be back home. Now you can return to your life,” Princess Celestia said with a smile.

“Yea, you see... about that...” Spike said, digging a foot against the ground.

“Hmm? What's the matter, Spike?” Twilight asked, turning her head curiously and finally noticing that Spike was wearing a dog collar. “And... are you wearing a..?”

“Oh, yea, forgot. I... kind of got used to it,” Spike said, lightly running a claw over the dangling gold tag. His name was cut deeply into the surface, the letters enhanced with silver inlay.

“At the very least my biped doppelganger has exquisite taste,” Rarity said, leaning in to examine the tag. “And, if nothing else, it serves as an excellent souvenir of your time in that world. That and your memories.”

“Memories... that's what I have to keep with me... when I go back...” Spike whispered.

“What? Go back?” Twilight asked, looking down at Spike.

“I... I got very attached to them. I can't imagine being away from them. I know that you all miss me. And I miss you but I... well, I got close to them. Very close,” Spike said, a smile sliding onto his face without him even realizing it.

The others talked amongst themselves, Rarity noticing the smile and faraway look Spike got. He was clearly elsewhere, and wanted to be back. “Tell me, Spikey-wikey... would it honestly hurt you more to stay here, your home, amongst all your friends than it would to return?”

“I don't... I mean... I wish I could stay but... I have a life there now. A life that I like a lot,” Spike said, looking back at his reflection in the mirror.

“Even... as a dog?” Rarity inquired.

“Yea... even as a dog,” Spike answered, aware that Rarity understood what he was trying not to say.

“She... must be nice, this other me... I mean, to take you in and make you so loyal and dedicated,” Rarity said, quickly. “I almost... envy her.”

“We spent a lot of time together. And she didn't think I was a kid, her friend's little brother,” Spike said, evenly.

“Yes. Yes you are not just such... you are your own dragon. She was very good to see that,” Rarity said. “I presume you... have made this friendship very robust, if I may be so bold.”

“We're close. And I don't want to leave,” Spike said, looking down and blushing again.

“Twilight...” Rarity drew Twilight aside, and spoke quietly to her. “I believe we should allow Spike to return. Perhaps let him stay here for the duration of the portal's activity but send him back before it closes.”

“Rarity... are you sure? I mean, this is his home...” Twilight looked over at Spike, who was glancing constantly to the mirror.

“I am certain, Twilight,” Rarity replied, smiling sadly at Spike. “He has formed a life there, a different and more satisfying life than he has here. He will never forget us, but he will never cease to think of the life he left if he remains.”

Twilight sighed. “If you say so. Just from what he said I see you're probably right. It'll be hard to be without him, like it was from those two years. But at least this time we can say goodbye.” Twilight turned around to Spike and smiled. “If you want to go back I won't stop you. We'll all be sad but understand. If you could just go back and tell them you'll be here until the portal closes. I promise we'll get you back here in time.”

Spike's tail wagged happily and he rushed up to hug Twilight. “That's great! I'll rush back, tell them and be back here. I'm sorry but I have to do this.”

Twilight released Spike and wiped at her eye. “I know. I trust that you know your own feelings. Go on, we'll be waiting. Pinkie will...” Twilight looked back and noticed that Pinkie was gone, leaving nothing but a fading dust silhouette. “Have a party ready well before you get back.”

Spike laughed a little bit and nodded. “Thank you, Twilight. I'll be fast...” With a final look, lingering on Rarity, he leaped into the mirror and vanished into the rippling silver.
