Chapter One: A Discovery

"Hey Big Mac, what's up?" Said Spike as he casually opened the screen door to the Apple family's home.

"Hey Spike." The imposing man said, looking up from a copy of the Ponyville Times. "Here to see AJ?"

"Yeah, she around?"

"Eeyup, in 'er room. Said she has a surprise for ya." Big Mac said before returning to his paper.

"Oh boy," Spike said, half joking, half with actual excitement. "Thanks". A surprise out of the blue wasn't exactly something Applejack was known for and when she did they weren't exactly the best gifts. Spike remembered his last Birthday, when she got him a shoe horn. Like, seriously, who uses a shoe horn?

Spike made his way up the Apple family's rickety staircase and opened Applejack's bedroom door, adorned with a single red apple.

It was a very old simple room; bed, table, lamp, wardrobe, a painting above the bed, a few books scattered on the floor. However, it's most prominent feature however was the blonde beauty standing in the middle of the in nothing but her tighty wighties and her signature stetson hat. Her 23-year-old body was perfect in Spike's eyes. Before dating Applejack he would have normally gone for a lean and slender figure that was more akin to Rarity's frame, however, he had matured after his 18th birthday and realized that he wasn't the right man for her but he eventually saw a woman who had appreciated him in a more non-platonic fashion and had grown accustomed to the gorgeous body of a certain country gal. Her face was strong with a solid chin and jaw, sharp nose, and deep green eyes paired with a triad of freckles on each cheek would make her a dark horse in a beauty pageant, she had a surprisingly small stature for her muscle situation but it simply added to her unappreciated cuteness, her arms and legs were muscular from years of farm work and apple bucking, her breasts weren't what every man desired coming in at a small B cup (not that it mattered to spike) with perky nipples and large, pink areolas, but, one of her best features was her shapely hips and ass, while she was fit and muscular she was also fat in all the right places, her ass was well formed over years of maturity, it was firmed but still had jiggle to it and it had little to no sag to it. Needless to say, Spike was the envy of many men and a few woman of Ponyville.

"Y'alright there, sugarcube?" Applejack asked with a sarcastic eyebrow raise. Spike had forgotten that he was simply just staring at her ass in those tighty wighties, giving her a slight wedgie to highlight her magnificent valley of a- "You're doin' it again."

With that, Spike finally snapped out of his ass trance and noticed Applejack was looking at him. "He he, sorry. It's just... Y'know. Pretty great." Spike said with a light blush on his face while rubbing his arm up and down. "Mac said you have a 'surprise' for me?"

"You can stare all you wan', partner. It's yours, y'know~?" Applejack sang while seductively sauntering over too Spike. She wrapped her arms around Spike's shoulders and leaned in towards him to plant a kiss against his course lips. She ran her wet muscle against her dragon lovers sharp canines and incisors. Spike replied to her advance with much gusto as he quickly darted his reptilian tongue into her mouth and comforted it in it's familiar surroundings. There tongues danced a familiar dance, both fighting for dominance, Applejack often won the battles of the tongues despite Spike's more elaborate tongue. Spike jerkily traced the tips of his claws over her ass cheeks before lightly squeezing the large soft, globes causing applejack to elicit a soft moan into his mouth. He then moved his hands up her back and softly wrapped her arms up her back and lightly dug his claws into her back, enough to puncture the skin and draw blood. Applejack quickly gasped and separated the kiss. Applejack's kissing game was strong but Spike's hand game, while a little awkward, was stronger. "Your gonna pay for that y'know." Applejack said in a playful tone, as she drew him closer to her face.

"Um, How?" Spike said in an attempt at a playful tone. Spike's dirty talk wasn't stellar and he often found himself frightened by Applejack's forwardness in her bedroom pursuits, she often had initiate sex while Spike just sat back and waited.

Applejack rolled her eyes at Spike's idea of dirty talk. "Your surprise is how your gonna pay for that." Applejack whispered seductively into his pointed ear. "Take of your clothes."

Spike obeyed her commands in fear of what would happen if he didn't. He removed his T-shirt to reveal his awkward young adult frame. While he had lost all of the baby weight from his pre-teen years, he now had a very skinny frame due to his awkward puberty. He had managed to put on some muscles in his arms and chest from lifting books at the castle library and doing work around the farm, but, hardly Big Mac in stature and physique. After removing his shirt he took of his shoes and unbuckled his belt and took his jeans and underwear in one fell swoop. His cock was already erect from the make-out session a few moments before. Once again hardly Big Mac but it was a decent size. It was about 6.5 inches and had a diameter of about 1.5 inches, it had a long thick vein running from the base to about halfway up his shaft were it forked, the head was a light shade of purple covered by a tight foreskin, there was a lack of pubic hair in fact a lack of most bodily hair from the head below, Spike pinned it too his dragon biology, it gave his body a rather strange but appealing nature, his balls were smooth and larger and lower than average, Spike wasn't sure why and often found it a nuisance most of the time but Applejack loved playing with them and often gave them 'special' attention. Despite his average size and his insecurities about his member, Applejack found it perfect, and especially liked what it was attached too.

"Close your eyes." Applejack announced, dropping her playful tone. Spike answered her call by quickly shutting his eyes in fear of what would happen if he didn't. As he was greeted by the darkness, he relied on his other senses to predict her next movements. He head her step over to a nearby wall then to her vanity, she then took a few precarious steps towards him, he could already smell the light scent of her arousal in the air, by now she was almost in his face and he could feel her hot breath tickling his skin. However it was a surprise stroke to his erect cock that made him jump out of his skin. "Shh, calm down, sugarcube. Let's take this slow." She whispered, resulting in a chill running down his spine. She then dropped an object with a lot of weight around Spike's neck, he still refused to open his eyes, especially with her muscular hand having a firm grip around his shaft. She removed his hand from his cock to pick something up from her bedside table and placed a tight metal ring over the head of his dick and slid it down to the base and tightened it around the base of his shaft, it was tight and uncomfortable around his cock. She walked around to his back. A drop of sweat ran down his brow, partly due to fear of Applejack's ideas and secondly due to the hot summer weather. He felt his hands being yanked behind his back and being quickly tied with a thin length of rope. He gulped hard but it also sent a rush of blood to his already throbbing member. "Alrighty, open 'em."

Spike opened his eyes, not much had changed Applejack was in front of him, he was still naked, but... There was a long length of rope around his neck connecting it to Applejack's closed fist. He also noticed that his hands were binned behind his back in a tight knot, but not as tight as to constrict his blood flow.

Spike looked down at his makeshift leash. "So is the surprise me being lynched?" Spike joked.

"We ain't gettin' that kinky..." Applejack shot back. "Yet." She muttered under her breath. She pulled on Spikes leash towards her en suite bathroom. Spike stumbled as he got used to his new attire and dominant girlfriend. She turned him around so she faced away from the bathroom door. "You jus' stay here an' don't move a muscle." She ordered while giving his cock a frighteningly tight squeeze. She then slipped into her bathroom and Spike waited... And waited, and waited, and waited, and waited. You know how time slows down when your stood naked in bondage gear. "Alright, turn around."

Spike swiveled on his heels to face his girlfriend and probable future mistress. He wasn't ready for what he saw. Applejack wasn't one to dress up for sex, she always thought it was weird that people would dress up for something when they would just end up sweaty and bodily fluid-y. However, for this occasion she made an exception. She stood in the door way wearing a red novelty cowboy hat decorated with a white lace around the rim and a red heart in the middle, a pair of cowboy boots with a signature red apple stitched into used for special occasions only, a brown pair of fancy leather work gloves and brown leather thigh highs. Along with all of this she was also without her underwear this time and showed her blonde pubes stylized into a long landing strip running up her pubic mound along with some short pubic stubble around the general area.

"So, whatcha think?" Applejack questioned, looking for a good answer.

"It's ver-"

"I doesn't matter what you think!" Applejack declared without remorse for Spike's answer. "Lay on the bed." She ordered while pulling tightly oh Spike's lead. Spike obeyed her order swiftly and laid down straight as a plank on her bed. He felt a shift in weight on the mattress as Applejack climbed onto the bed with him. Spike was half-scared and half-aroused by the sight of his dominant lover kneeling over him with a smug look oh her face. He whimpered in fear when she bent to where they were at face level. "The safe word is Apple or just give me a signal."

"Apple, really?"

"Expectin' somethin' diffrent?"

"Not really. Love you."

She quickly kissed him on the lips. "Love you too" Then she quickly slapped him across his cheek. "You'll call me 'Princess' from now on, You'll speak when spoken to and you won't step outta line unless you want punishment. Is that understood?" She asked, not looking for an answer but acknowledgement.

"Yes. p-princess" Spike stumbled out in fear.

"Good." She stood up and stepped over his head to the point where here boots where dangerously close to his head. "Now, since ya were so keen to stare earlier like the filthy pervert ya are. Ah think you should put that tongue to some use." She knelt down to where her slick folds were mere centimeters away from from his face, her pheromones were pungent in his heightened sense of smell. He happily obeyed as hey began to lustfully lap at her wet cunt. Once Applejack found out how good Spike's tongue was at scratching certain 'itches' she put him to good use and often treated herself with cunnilingus from her lover. Spike also loved giving it, something about bringing her to a quivering orgasm using only his tongue was satisfying. He continued to tease her pink entrance until Applejack took the plunge and lowered herself to the point where she was smothering him with her pussy. "Alright, ride em' cowboy~" Applejack said as she played and stroked his cock and balls teasingly.

"mmmf yes princess." Spike managed to get out between servicing his 'princess'. With the guidance given to him, he delved his tongue into her inner canal and started stroking her inner walls. Applejack replied to this action with a series of groans and grunts gradually getting louder as Spike played with her insides. He lathered her inner walls with his saliva and flicked his forked tongue inside of her. He pulled of some of his regular moves, making his tongue into a figure of 8 and feeding it through her canal, using it as a pseudo-penis and thrusting it inside of her as he flicked at her clit or just stuffing as much as he could and going crazy inside. This usually reduced Applejack into a sweaty pile of a woman, however she managed to maintain her composure apart from some loud moans. Spike had to pull out the the big guns, he retreated his muscle from her sopping cunt and slowly traced it up to her puckered anus. Applejack was always partial to a bit of anal play, she found she was very sensitive in that region at a young and often got playful with her rear and once Spike came into the mix she was happy to introduce him to her sensitive asshole, however, anilingus hadn't come into the mix yet. Applejack gasped loudly as Spike's forked tongue danced at her 'backdoor'. At this exclamation of her pleasure Spike knew that this was how he would bring down. He pushed his tongue into her tight hole and shortly ran it up her sides. Applejack was in heaven, she could feel his every taste bus, muscle contraction and hot breath in her inner walls, she could feel her orgasm on the edge and waiting to be pushed off. She reached down to her engorged clit and started rapidly rubbing in circles, desperately trying to reach her climax.

"You like that, wanna make your princess cum? HARDER, DEEPER, YES, RIGHT THE-" Applejack would've continued her sentence if it wasn't for the powerful orgasm that rocked her body and made her silently wither and curl up into a shell of her former self. She stayed like this for a few seconds as the electric love swept fro her head to her toes, afterwards she quickly recomposed herself while still enjoying her previous climax. "Well then, you did good. But you did do something when you weren't told." Applejack moved down to his crotch and started to rub herself up and down his shaft while facing away from him, covering his cock with her slick juices."Best get used to this. It's all ya' gettin'."

Spike wanted to exclaim his outrage with that statement but knew he would only get 'punishment'. This is bullshit. Spike thought. She throws me into the deep end, I give her what she wants and she doesn't even give me anything good. It made him so angry. So angry he could see red... Literally, he was seeing red. His vision had gone a dark shade of red, the only thing that wasn't red was Applejack who was a light shade of yellow. He could feel the heat radiating inside of him at high temperatures. He could feel his joints getting stiff. He could feel the strength inside of him rising and his inner fire raging. The rope binding his hands was involuntary broken with little defense.

Applejack had stopped grinding on his dick. "Y'alright? You're really fuckin' hot." She turned to face her overly warm lover but before she could she was tackled and bent over. "Woah nelly! What the fu-" Before Applejack could finish her sentence, a scaled, clawed hand roughly gripped here hanging tit. She looked back in fear to reveal a pair of red, reptilian eyes staring deeply into her eyes and thin bellows of black smoke coming from his nostrils. "Spike, what the hell is wrong wit'chu?" Spike answered her with a swift slap across her cheek.

"Master." Spike said demanding. Applejack felt the pain spread across her body like an electric shock. She was terrified and exhilarated at the same time. She let her head fall to the mattress, knocking her hat off. She looked in between her legs and gasped at what she saw. Spike's member was erect and engorged, it must have been double the size and still growing, his shaft and head was red with the influx of blood to his now huge cock. However Applejack was not prepared for what she saw next. The metal cock ring that she had placed on him previously was creaking as the mechanism was stretched by Spike's growing cock. Without warning it snapped and fell to the sheets below as thick globs of pre-cum came from his tip as his cock hung and swayed to and fro, not being able to support it's own wait.

"Sweet Fucking Celestia." Applejack muttered as she admired his now huge package.

She could see thick and jagged scales travel up his legs from his feet, ripping the sheets as they snaked up his legs. It stopped just above the knee. His arms did similar but stopping at above the elbow and gave him long, razor-sharp claws instead of his fingers. This paired with the pair of red eyes looking down at her from his dominant position made Applejack's pussy drip with... Anticipation.

Applejack happily welcomed this new change in her lover. With her previous relationship she had always been the dominant one, it even scared a few of her previous boyfriends away. But now she saw things at the opposite end of the spectrum, she loved it! After her and Spike's awkward previous sexual encounters she finally got to see his dominant side. And she loved it! He was beast, finally giving into his most carnal desires, his primal instincts were finally released and all focused on one thing. Fucking the girl in front of her witless.

He lined his pole up against her willing pussy, and rubbed it up and down her slick folds. The heat radiating from his cock was almost unbearable for Applejack but it felt so right to her, she so desperately wanted his scolding dragon cock inside of her, she longed for it, she needed it. "Please, put it in, please put it inside of me."

"Why should I? You weren't gonna let me before." Spike growled into Applejack's ear, she could smell the thick smell of smoke coming from him as it pillared to the ceiling.

"Please, PLEASE. I'll let you do anything you want with me. I'll let you fuck me anyway you like. Call me anything. JUST FUCK ME, MASTER!"

Spike tugged back on her hair, pulling her head back to face him as she gasped from the quick stab of pain. "Good girl." He growled. He then planted his lips on hers and shoved his tongue into her mouth and started tackling her tongue, Applejack attempted to get in on the battle but Spike quickly took her over and wrestled her wet muscle in her mouth, wrapping his long tongue around hers and constricting it like an anaconda.

He separated the kiss, with a long string of saliva connecting their mouths together. He took his cock in his hand and placed it at Applejack's pink entrance, he then grabbed Applejack by her shoulders and , without warning forced her all the way down his huge length. All the air from Applejack's lungs and she had to gasp loudly to get her breath back, he was huge, but he felt like twice the size inside her. She thought she would split in half taking his cock. It was so hot... So very hot. He took his cock all the way out of her willing cunt only too shove it back in again, Applejack groaned loudly in mixture of pleasure and pain as Spike fucked her deepest nooks and crannies.

"You like that, don't you? You dumb fuckin' hick."

"YES, yes. Please fuck me, Master."

Spike ravaged her pussy again with his manhood. And again, and again, and again, and again, and again. Spike kept up his routine until Applejack was practically screaming into her pillow to muffle her cries of ecstasy. Spike just manged grunts and groans or occasionally calling Applejack a 'slut' or a 'simple cock sleeve'. Applejack's mind was blank, her eyes rolled into the back of her head, the pillow was wet with her saliva. She could feel a huge orgasm coming soon. She needed it, she needed something to push her over.

"Please hit me master." Applejack didn't know what had gotten into her. Anyone who hit her would be in for the beating of their life. But she wanted this climax so badly, she had to do something to get her their.

Spike grabbed her by her throat and pulled back with his cock still buried deep inside of her. He then raised his clawed hands in the air and laid a heavy strike across left cheek. Applejack squealed in delight as the pain spread to her face and the blood rushed to her face. Spike also appreciated this new technique of love making. Applejack was a stubborn bitch to him and she needed to be put into her place, and he was the one to do it. He put another slap to her already red face and Applejack screamed at the top of her lungs. Every nerve in her body was experiencing absolute euphoria, her entire body shook, the heat spread through her like a fire, her mind went completely blank, her toes curled, her tight pussy contracted around his cock, she was at a loss of words, except for:

"GAAAAAAAAH-FUCK. HOLY MOTHE-" Spike put a hand over her mouth before she could finish her cry of pleasure as he was close to his own paradise. With just a few more thrusts into her pussy he fully hilted himself inside of her and pulled back his head and roared triumphantly.

"GRRAAAAAAAHH!"

He felt his hefty balls contract and his semen shoot from his globes through his shaft. It erupted from his head and hit Applejack' cervix with some force. He shot rope after rope of his seed into deep into her pussy. It eventually started to fill up her inner canal and ooze out of the sides, it trickled down his balls and ran down her thighs. After a while the tidal wave of bodily fluids had subsided and most of it had leaked down Applejack's legs and had collected into a puddle on the sheets. Spike and Applejack stayed still for minutes, simply enjoying the afterglow of their passionate lovemaking, breathing heavily. Spike's dragon-like features had retreated and his arms, legs and eyes were back to normal.

"What happened?" Spike questioned between pants as he climbed up of off Applejack and fell back from feeling... Exhausted?

"What?" Applejack said, finally coming back to reality. She propped herself up on a weak arm and looked at her lover. Her hair was disheveled, her cheek was red and slightly swollen and she reeked of sex.

"Oh my... What happened to your face!?" Spike rushed to her and cradled her face and hugged her. "Who did this? When? Where are they?"

"Do you not remember?" Applejack asked confusedly.

"Remember what?"

"I was teasing you then you went all... Dragon and stuff and we fucked. You slapped me a few times."

"I DID WHAT!? OH MY CELESTIA, I'M SO SORRY. I DIDN'T MEAN TO, I DON'T KNOW WHAT HAPPENED. I'M SO, SO, SO, SO SORRY. PLEASE FORGIV-"

Applejack quickly tackled Spike in a hug and rolled him around so she was on top on of him on her bed and kissed him passionately. She separated the kiss and smiled the smile that Spike loved. "Shhhh. Ah loved it, sugar."

"Really!?"

"Yeah, you came outta your shell. We can be more natural now."

"Oh, OK. Your really not hurt are you?"

"Nah, but thanks for worryin'. Love ya."

"Love you, too." Spike then placed a loving kiss onto her lips.

A pair of white pumps attached to some long, toned and sexy legs made their way up the familiar path to Sweet Apple Acres.

Rarity was humming a happy tone to herself as she jauntily made her way to the Apple Family house. She needed to ask for Applejack's help for an errand she would do tomorrow and figured the orchards were the best place to look for her friend. As she approached the house she saw something in the window of where Applejack's room would be. Two human shapes moving at a fast pace. It seemed they were performing some kind of physical activity.What kind of exercise would two people be doing in their bedroom? Rarity thought to herself.

"GAAAAAAAAH-FUCK. HOLY MOTHE-"

"GRRAAAAAAAHH"

"Oh..." Rarity muttered realizing what was happening.

"Oh my..."

A red faced Rarity quickly swiveled on her heels and briskly walked back to Ponyville. She could do that errand by herself.

Author's notes

Hey. Thanks for making it this far. As I said, criticism welcomed (be gentle, it is my first time *blushes*)
Just had the idea for this one day and thought why not. Anyway, I might continue this by throwing Rarity into the mix. Hope you enjoyed!

Chapter Two: The Continuation of said Discovery

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