Twilight Sparkle and her diamond dog servant share an intimate rump in bed.

Servants were born to serve, and Twilight's newest – and only – servant does his job to perfection. Even with him being a diamond dog from underground, social barriers don't exist between the two and a friendship beyond servant and master is made almost instantly. Even after a few months of him working diligently for her, Twilight starts to think about past kinks and after a routine massage the stage ends up getting set for such. Deciding to ask her servant that very important question, she hopes that he'll end up giving her that special touch she desires.

Very doubtful he'll say no to her anyway, considering if he says yes, he'll end up fucking the hottest piece of pony ass Equestria can offer.

In Which Everyone's Favorite Purple Princess Takes A Dog Dick Up Her Ass.

The day was finally coming to an end, and, for Twilight Sparkle, she couldn't have been more happy. Flying gracefully yet somewhat sloppily, Twilight sighed as the final tasks of her long day were complete. Thanks to her being a 'proper' princess instead of one that just stands around and looks pretty, Twilight had found that the duties that came with princesshood were tiring and mentally draining.

Quickly coming in for a landing, Twilight readied her body before coming to a stop on the ground and closing her tired wings. As she closed them, she let out a whine of pain and quickly brought a hoof up to nurse them.

"Gods, I hope I don't have to fly around Cloudsdale again anytime soon," Twilight whimpered as she opened and closed her wings a couple of times in an effort to make them feel better.

After a few seconds of tending to her sore wings, Twilight turned her gaze towards her house and looked forward to crashing on her bed and sleeping for the rest of the day. As she looked forward, she stopped and a small frown came across her face. Instead of the treehouse she was so used to seeing everyday when she got home, a big castle now rested were the embers of her previous home were still fresh. While she was happy to have a roof over her head, lots of books and cherished memories were in her old treehouse and now burned to simple ashes. It still took her getting used to, but as she continued to stare, she saw a large bipedal figure walk past her window and for the moment she forgot about her old home.

"Hmm, seems Dogg is still hard at work," Twilight said softly as she smiled and started to walk forward. "Still feels wrong to have my own servant though."

As she walked, Twilight put her thoughts towards her new servant. At the command of Celestia, Luna, along with Cadence and even Shining Armor, Twilight had been told that since she now lives in her own castle, a personal servant had to be assigned to her. Like Spike, who still lived with Twilight but also had more tasks than before, Dogg pretty much cleaned the house and made sure that when Twilight came home, a nice warm meal awaited her and a clean bed did as well. While Twilight didn't like the idea of having a servant, she did see the reasoning behind it. Considering she was the Princess of Friendship, Twilight was specially tasked with promoting friendship with the other races around Equestria. Having a member of one of the races working under her was supposed to set a good tone, yet for Twilight it still felt wrong in her eyes. Coming up the steps and stopping at the large door, Twilight reached out to open it, but, before she could, it opened for her.

"Good evening, my princess," a slightly raspy, yet somewhat refined voice spoke out as the lanky figure of her servant came into view.

Bowing his head before Twilight, the diamond dog, whose name was simply Dogg, stayed quiet as he felt the eyes of his master wash over him. Taking a quick look at him, Twilight was very surprised the day she gained him as her servant, but only because he looked very well groomed. Unlike her one time underground when she was still a unicorn, Dogg was a diamond dog that wasn't unruly, uncivil, or even barbaric. He was well mannered, very obedient to the point it worried Twilight sometimes, and he always took very good care of himself. While most dog coats would be littered with filth, Dogg's coat shimmered with a clean shine. Even though his coat was a dark black, Twilight and even ponies around town weren't afraid of him. When he went out on Twilight's orders to enjoy time with the community, Dogg always offered a paw to ponies that needed help.

"Good evening, Dogg," Twilight replied with a smile as she nodded her head in approval, allowing him to raise back up. "Did you have a good day while I was gone?"

"Yes, my princess. I cleaned your personal chambers and made sure your bed is prepared for you," Dogg replied as he got back up and moved out of her way.

"Thank you. Did you also go out and visit today as well?" Twilight asked, knowing very well that Dogg sometimes stayed inside all day and simply cleaned.

"Yes, my princess. As you instructed, I spent a small part of the afternoon around Ponyville."

"Ah, good. Sorry I ask this question every day, but having you stay inside worries me," Twilight spoke up as she started to walk into her home. "Just because you’re assigned to work for me doesn't mean you should stay inside all day."

"I understand, my princess, but you shouldn't worry. I have lived underground most of my life and I'm still getting used to... seeing the sky," Dogg replied as he looked out a large nearby crystal window and saw the sky before he shuddered slightly. "Hopefully I'll stop worrying about it eventually."

Twilight said nothing for a second, understanding Dogg's fear of being outside. Back when she lived in Canterlot and was studying under Celestia, Twilight herself had a similar fear of being outside. Thanks to her long hours of studying, Twilight grew so attached to being indoors that anything that didn't have a roof scared her. Thankfully she got over it and she hoped that encouraging Dogg to go outside more often would help him.

"I understand, Dogg," Twilight replied as the scent of something cooking got caught in her nostrils. "Mhmm, is that... hay fries you're baking?"

"Yes, my princess. I know how much you love eating hay fries and oat burgers after a long day," Dogg replied as he turned around and began to walk towards the kitchen. "I shall bring your dinner to your room."

Twilight said nothing but smiled at the fact she was about to eat one of her favorite dishes. To further the point, her stomach let out a low rumble and she blushed before she started walking to her chambers. Even as she walked, Twilight did have to think about the upsides to having a servant. He loved to talk and read books with her, always kept the conversation going, and even showed great intellect in certain fields of subjects, sometimes more than even she had. While those were mostly underground culture and gem mining, Twilight was very thankful to have an intellectual diamond dog living with her. On top of that, she would always come home to a cooked meal and a clean home; she loved every second of it.

"It's not so bad I guess," Twilight spoke with a sigh as she began to trot for her living area to eat.

~~

Twilight sat on her bed, a lone candle flickering and lighting her surroundings as she looked over a ledger full of numbers and such about the town’s emergency funds. Even though it had been about half a year since the battle with Tirek, the destruction of Twilight’s tree house ended up causing more damage than first anticipated. Shrapnel and such had been blown through other house windows and there was widespread fire damage thanks to everyone being drained of power and unable combat it at the time. As she studied the numbers before her, Twilight looked up from the ledger and let out a yawn.

“Ughhh, I need to get to sleep,” she moaned as she closed the ledger, pushed it to her side table, and then sank her face into her soft pillows below.

As she laid still, her wings ached at her sides. Still sore from the long day, Twilight groaned with discontent as she opened and closed them in order to relieve the pain. It didn’t work, and Twilight knew her night would most likely be sleepless.

“Your tea is ready, my princess.” The sudden voice of her servant came from the door and, turning her head to see him, Twilight smiled weakly as Dogg walked in with a silver platter. Seeing a crystal tea cup and pot on top of it, Twilight pulled herself up without groaning and gave her eyes a quick rub to be rid of the blurriness building up in them.

“Mhm, thank you, Dogg,” Twilight spoke up as her servant put the platter on the side table near her and got ready to leave.

“You’re quite welcome, my princess,” he replied as he bowed to her.

Quickly pulling himself back up and getting ready to turn around, Dogg couldn’t help but notice Twilight had a look of pain on her face.

“Is… something wrong, my princess?” Dogg asked.

“Hmm? Ah, it’s… it’s nothing, my wings are just a bit stiff tonight,” Twilight replied as she continued to move her wings.

“Hmm, would you like me to massage them tonight, my princess? You always seem happy when I do,” Dogg replied as he moved his paws about, getting them ready to work.

“A wing massage would be nice, I guess,” Twilight replied, knowing very well that Dogg had a talent for making her wings feel better.

Dogg simply nodded and began to walk towards the bed. As he did, Twilight turned to her eyes to the large light fixture above and magically lit it up. Once bright enough Twilight then turned her attention to her nearby candle and blew it out. Once the room was lit in a soft blue aura of light, Twilight sighed and laid on her stomach on her bed.

Closing her eyes, Twilight listened to her servant’s foot steps as he approached. Once he was close enough, Twilight heard him reach into a drawer in the side table. No doubt he was pulling the massaging oil out, and just the thought of the soothing liquid rubbing against her burning wings sent a shiver down her spine. The shiver went to her neatly combed tail, causing it to flicker about and give the approaching diamond dog a beckon. The tail movement caused him to hurry further, and, popping the top on the bottle open, Dogg spurted a fair amount of the cold liquid into his paw.

“Shall I be gentle with them tonight, my princess?” Dogg asked as he put the bottle down and then slathered his paws together.

Twilight simply mhm’d at him with approval and stretched out her wings fully. With Twilight’s wings opened, Dogg walked to the bedside and began to reach out. Wasting no time, Dogg rubbed the palm of one paw near the base of her left wing in an attempt to see the reaction. The wing flinched before it relaxed, and Dogg quickly brought his second paw up. Touching the other wing, Dogg gently gripped both of them and slowly began to stroke his paws up and down.

“Ah! Ahhhhhhh, that feels nice,” Twilight spoke out as her back tensed up slightly, but she quickly relaxed and began to enjoy the touch.

Dogg said nothing to her, instead he moved his paws down slightly and rubbed both the middle of her back along with the base of her wings. For a few brief seconds, Dogg let his claws dig softly into her flesh and he gently rubbed the area around her wings.

His efforts earned him a moan of approval from Twilight, and for about twenty seconds he worked the area until he sent his paws back up her wings. Instead of stopping at the middle point of them, Dogg slowly moved his paws all the way up. As feathers came in contact with his paws, Twilight cursed under her breath at how good it felt. The once cold liquid was finally starting to heat up for her, and arching her back slightly to make the sensation last longer, Twilight bit her lip as Dogg’s paw finally came to the tip of her wings.

“I take it you enjoy this, my princess?” he asked in a modest tone as he let go, only to bring his paws back down to the base of her wings and repeat the motion.

“Very, that feels good on both my wings and back,” Twilight replied, her face still buried in the pillow, yet off enough to speak clearly.

As she finished her sentence, Dogg moved his right paw to Twilight’s left wing and used both paws to rub it. Cupping them around the bone, Dogg continued to stare at the bottom of her wings and worked his way up slowly. The extra feeling of another paw caused Twilight to ooh and awe with glee, and she was sure her body was starting melt from the wondrous touch.

“Mhmmm, you’re doing very well,” Twilight complimented him on his good touch in a low tone as her tail swished about mindlessly.

Again Dogg said nothing, and, after a few minutes of working her left wing until the liquid was worked into her, he moved both paws to her right. As his paws left, Twilight let out a sigh and gently closed the warm, nurtured wing. No longer feeling stress in it, she smiled at him over her shoulder and watched his face. Unlike her ever changing expression, Dogg kept an almost completely neutral one on his face, save for the small smirk at the side of his jaw. Why wouldn’t he be smiling? He was providing excellent pleasure for her and she was enjoying every second of it.

Finally, after a bit, Dogg let out a sigh and pulled his paws away. As he did, Twilight flexed the wing he rubbed before she gently closed it.

“Mhmmmm… that’s what I needed,” Twilight cooed, her eyes closed and her body mostly relaxed.

“As long as you’re happy, I’m happy, my princess,” Dogg replied as he got ready to move away.

“Umm, before you go,” Twilight spoke up as she adjusted her body but found her lower back still a bit stiff. “Could you rub my lower back? I… feel a knot in it.”

“Shall I be gentle like before or do you wish for me to work it hard, my princess?” Dogg asked as he gave his neck a crack and got mentally ready for a second round of treatment.

“Please work it hard,” Twilight replied as she wiggled her lower body and cringed slightly as her back stiffened even more.

With the order given, Dogg wasted no time and put both his paws to her lower spinal area. Pressing hard and firmly, Dogg dug his claws in a bit before pushing upward. The sudden actions made Twilight lose her breath, and for a few seconds her mouth hung open as no words left it. Once Dogg reached the middle of her back, he turned his paws downward and went in reverse. Thanks to how firm he was pressing, Twilight instantly felt a few bones and joints pop in her back.

“Awweee, that’s what I need,” Twilight spoke in a single breath as Dogg planted his paws on her lower back and rubbed circles into it.

As his paws moved, Twilight felt the upper edges of her rump being pushed as well. The closeness didn’t bother her, in fact, Twilight loved it when his claws would knead her plushy purple butt. Even with him touching her butt, there was never anything sexual that came from it, but Twilight did find when he massage it, he always left quickly afterward.

Her thoughts were quickly cut off as Dogg placed two furry digits on her lower spine and dug deep into it. As sore as it felt for Twilight, she remained quiet as she let him work the tense muscle into relaxation. Thanks to remnants of the massaging liquid on his paws, Twilight felt it being worked into her back and helping her sore muscles relax. For a few long seconds, Dogg worked his digits expectantly until he started to rub more gently. As he did, Twilight let out a sigh, but the gentleness quickly left. Pushing both of his paws into her spine, something popped and Twilight froze up.

“Ahh, there we go,” Dogg said quietly as he started to move his paws again, but instead of being hard he gently rubbed the spot that cracked.

“Oooohhh, that felt gooood,” Twilight cooed deeply as she nearly drooled from the sensation.

“Satisfactory results, my princess?” Dogg asked as he pulled his paws away.

“Very much so,” Twilight replied as she started to roll over.

“Hmm, seems I did better than I thought.”

Wondering what he meant, Twilight adjusted her back leg slightly before she froze up and blushed. As her thighs rubbed together, a hint of wetness could be felt coating her fur.

“Oh… um, sorry,” Twilight stammered out as she looked up at her servant but found him looking the other way while his paws reseted in front of his groin area. “I… I uh… guess I enjoyed that more than I should have.”

“It’s quite alright, and if you are… ahem, well, like that right now, then it just means I should leave the room and let you tend to your needs, my princess,” Dogg answered back as he found it a bit harder to breathe easily and felt his calm attitude slipping away.

There was truth to his words, but, for Twilight, she wondered if he would be leaving the room with a greater need than what she was experiencing.

“And what about you?” Twilight asked, her eyes staring at his paws.

“And what about me, my princess?” Dogg asked back.

“Well, I know I do have my own needs that need to be attended to,” Twilight said as she pulled herself up and rested her wetness against her bed sheets. “But I’m more worried about you.”

“You don’t need to worry about me, my princess,” Dogg replied with a smile as he tried to take a step back. “We each tend to our own needs in our own way.”

“I know that, but… I feel like I’m not thankful enough for what you do for me,” Twilight replied, knowing very well the situation she was going to be putting herself in. “You make my meals, you clean my room, and you make sure every day that my house is perfect and in pristine condition. To top it off, you never ask me for anything for you. So... because of these things, I feel like I should show you how appreciative I am of having you around.”

Dogg stared quietly at Twilight for a few seconds, allowing her to think about what she was doing. As he stared, Twilight took the time to try and play more to him. Laying on her side and still facing him, Twilight lidded her eyes slightly and gave her servant a seductive smile.

“My princess… are you implying what I think you’re implying?” Dogg asked as his eyes traced over her slender frame, but ended with him looking at the floor.

A princess attempting to seduce a servant? While her way was unrefined and showed it wasn’t something she was used to, Twilight still smiled at him. Though it was mostly gratification Twilight wanted to show to him, there was her own personal thoughts on the matter. To put it bluntly, she was alway curious about diamond dog anatomy, and thanks to her time living in Canterlot as a young mare, she had plenty of books to look at. Some were for study purposes, thanks to Celestia’s aids wishing for Twilight to be well studied in all the species in and around Equestria’s mainland. Partly to blame were her growing hormones and the rather explicit pictures lots of the books had, and though she studied, she grew curious. As much as she loved to read, Twilight liked to be more practical with her studies. If she could mix a potion, try out a new spell, or even meet a different species residing around Equestria, she would. Now she had her own diamond dog servant, one she could study, live with, talk to, and now that the chance was presenting itself, she could explore the sexual ways of one, rather than rely on a rather expensive rubber copy of a dog’s penis.

“Maybe, you do always make me feel better when you rub me down, and I do notice you tend to cover up and leave the room quickly. Come sit on my bed for a second,” Twilight said to him as she patted the sheets below her, beckoning her servant to sit.

Dogg hesitated for a second and did nothing, but, refusing to disobey an order, Dogg moved onto the bed, still keeping his paws firmly against his groin area.

“Now, if you are leaving the room every night sexually aroused thanks to me, then it should be something I help with,” Twilight spoke up as she got up, turned herself around, and laid back down, this time with her front hooves resting against his lap.

“You do understand the implications of this situation now right, my princess?” Dogg asked.

Twilight simply smiled at him. Oh, she knew, and even though he was of a different race, Twilight didn’t mind. Heck, she did grow up with a dragon most of her life. Sadly she could never do anything with Spike, thanks to the close bonds they had, and never got to really see first hand. All she had was an endless amount of books, but sadly there was a limit to what could be learned from them. First hand experience was always the best teacher, and when Dogg became her servant, the thought of exploring his body did cross her mind on several occasions. Now a means had shown itself to her, and just because it was in the form of her servant didn’t mean it was going to stop her.

Why would it? There had been several times when Twilight had a study session with Celestia in her younger days, and, on a fair amount of times, Twilight would hear Celestia in her room with a servant. If anything was shown by Celestia, it was that princesshood allowed for such actions both in the present and heavily in the past. Back then both princesses had harems of ponies and different races at their leisure, and that still remained to a point in the present.

“I do understand, and it’s been something I’ve wanted to try out for a long time. You deserve it for everything you do for me, and this is the least I can do for you right now,” Twilight spoke to him as she adjusted her lower body slightly and moved her face closer to her target. “But the real question right now is: Do you want it?”

Dogg said nothing. He could only stare at Twilight’s eyes as she put her front hooves on his lap and eagerly waited for an answer. Part of him wanted to say no, considering he was just a lowly servant, but he knew better. When first hired, he was instructed to obey anything Twilight asked of him and he wasn’t going to go back on what he was told, even if both of them were different species.

“Very well, my princess,” Dogg replied as he looked from her face, towards his paws.

Twilight followed his eyes to his paws, and as they started to move out of the way, her eyes lit up. Much like she already figured, Dogg was indeed starting to harden up and she couldn't pull her eyes away from his growing organ. The redness of it intrigued her, and just the length she could see so far excited her. She knew how diamond dogs engaged in sex and with him already starting to harden she wanted it inside of her.

Or rather, she desired to see if a dog's penis would fit up her pony butt.

"So that's what yours looks like," Twilight muttered as she reached out a hoof in order to feel it. "May I?"

"You may," Dogg replied in his well mannered tone. He could feel himself becoming more excited that she didn't push him away the second he revealed his most private part to her.

With that said, Twilight wasted no time in reaching forward and letting her hoof brush against the sensitive flesh. Once in contact, Dogg looked to the ceiling and let out a loud sigh that was shaky and showed his increasing nervousness.

"Just stay relaxed, Dogg," Twilight replied as she ran the edge of her hoof up and down the red flesh.

"Y-yes, my princess," he answered back as he took a deep breath, held it in for a few seconds, and then expelled everything he breathed in nice and slowly.

Though he was visibly nervous, Twilight did her best in order to not do anything very suddenly and abruptly. Instead, all she did was rub his growing penis with her hoof and inspect it with her eyes.

“Fascinating,” Twilight thought to herself as she continued to stare at the dog dick in front of her. “More red than the books always specified, but it looks just like one of my own toys. I can’t wait to enjoy it.”

As she pondered her thoughts and stroked her hoof, the penis finally found itself at the peak of its height, but Twilight knew she wouldn’t see the bulb of Dogg’s penis until she stimulated it more or quickly moved onto the the act of penetration. Part of her wanted to continue to play with it and mentally study it, but Twilight didn’t want to keep her servant waiting much longer.

“Dogg. I have a special request,” Twilight spoke out as she moved her hoof away.

“Yes, my princess?”

Opening her mouth to speak, Twilight only succeeded in leaving her mouth agape and her mind blank. Though she acted confident in approaching him for the option of sex, and actually rehearsed her previous lines before speaking to him on days where her naughty mind would imagine bedding him, any more words she wanted to get out were just not coming out properly.

“I wish… oh how do I say this without sounding silly,” Twilight started to say but quickly looked down and brought her hoof to her lips in order to quiet herself a bit. “Oh, umm… what’s it called again? Ah, anal! Could you do that for me?”

“Excuse me, my princess?” Dogg replied as he cocked one eyebrow at her.

“Um… well… uh… ah screw it! Dogg, would you be willing to um… stick it up my butt?” Twilight asked, deciding it was better to be blunt than not.

“You sure you want it up your… butt, my princess?” Dogg asked, rather unsure if it would be wise to end up fucking her butt and getting the knot stuck in it.

“Mhmm,” Twilight nodded as she left her mouth closed. “Don’t worry, I’ve… um… Like I said, I have toys and… I think you understand,” she added in as she still couldn’t get her thoughts out right.

“I do,” Dogg replied. “But… do you have any lube?”

“We’re just in luck!” Twilight replied as she started to pull herself up and turn herself around.

Continuing to watch Twilight turn herself around for him, Dogg's eyes widened and he had to refrain from letting his tongue roll out of his mouth. He had a perfect view of Twilight's pony butt, along with visible wetness showing on her pussy below. While he stared, Twilight had herself occupied by fiddling with her pillows until she lifted them up with her magic and picked up a small bottle of lube that was hidden under it.

"Ahh, so you do have some," Dogg spoke up as he saw the small bottle being floated towards him. "Honestly, I didn't think my princess had such a side to her."

"Well... it's... it’s actually for my... um... toys and such," Twilight said sheepishly as she blushed and didn't really know what to say. “Oh wait, I… uh, already told you that.”

"Ahh, my apologizes. If it makes you uneasy I'll stop talking about it," Dogg replied as he watched Twilight fidget in her spot and try to hide her expression.

"No, it's not you, it's just... always a bit awkward right before sex for me," Twilight replied to him as she continued to blush. “I’m just not used to talking about sex with others.”

"Ah, I see, then I should hurry up to make it less awkward for you." Grabbing the lube bottle, Dogg quickly flipped the cap for it and was about to pour it into his paw before he stopped.

"Almost forgot to clean my paws," Dogg muttered as he looked around for something to wipe his paws with. "My princess, I need to be excused for a second."

"Oh? Is... is something wrong?" Twilight replied, wondering if her being awkward around him was actually scaring him off.

"Nothing major, I just need to wash the massaging oil off my paws."

"Oh okay... ah, I’ve got water you can use right here," Twilight noted as she pulled herself to the side of her bed, before she started to pull the sheets up so she could see under the bed itself. "I always keep bottled water with me in case I need to have a drink at night… o-oh wait, you know that as well."

As Dogg watched Twilight light up her horn, the sound of something being pulled under the bed made his ears perk up and caused him to look to the side of the bed Twilight was looking at. A second later, both of them noticed a large bundle of water bottles being pulled out from under the bed. Though he actually forgot about putting the water bottles under the bed at Twilight's request, Dogg was thankful he didn't have to leave the spot he was in.

"Here you go," Twilight said to him as she pulled a water bottle out of the bundle. "You can also just use my sheets to wipe off your hands."

For a second Dogg paused and wanted to ask her if that was actually alright to do. While he thought about it, he only smirked and laughed initially as he knew the sheets were going to get filthy regardless. Watching Twilight continue to hold the bottle with her magic, he further noticed her take the cap off for him and bring it close to his paws. Putting the lube bottle down momentarily, Dogg cupped his paws and let Twilight pour some water into them.

"Just use the corner of the bed to dry your hands off," Twilight spoke to him as she gently poured the water.

Nodding with approval, Dogg waited for Twilight to stop pouring so he could began washing. Once she did, Dogg moved his paws to the corner of the bed and began to clean himself. Though water fell out of his paws and either hit the bed or even the floor below, neither said anything. While no words were exchanged, Dogg could see Twilight looking at the floor where the water was falling and that told Dogg to wipe up the mess afterwards.

"Don't worry about that mess either," Twilight spoke to him as she laid her body back on the bed and moved her tail back up. "You can clean up after we are done."

"Hmm, interesting to see my princess ignoring a blatant mess before her," Dogg remarked as he scrubbed his paws vigorously.

"No use cleaning up a mess when another mess is going to be made," Twilight remarked back as she stuck her tongue out at him and gave him a cheeky smile.

Dogg just chuckled and quickly wiped his paws on the sheets.

Once his hands were clean of the hot, oily liquid, Dogg looked at his paws one last time in order to see if he missed any. Not seeing nor feeling any of the warmness on his paws, Dogg quickly picked up the lube bottle and poured nearly all the remaining contents into his paws. While he would have rather cleaned his paws properly, Dogg knew better than to make Twilight wait any longer than he already should have. Gripping one paw on his shaft while resting the other against Twilight’s plush rump, Dogg took a deep breath and began to adjust himself. As the bed creaked and the sheets started to clump under both of them, both could feel the anticipation rising as Dogg rested the tip of his erection against her anus. Once both privates touched, Dogg wasted no time and slowly started to insert his erection.

“Ah... ah!” Twilight muttered out as she felt the foreign erection works its way into her.

"It's not hurting you is it, my princess?" Dogg asked as he moved his paw away from his erection and rested it on the other buttcheek of Twilight, wanting to be extra sure Twilight herself wasn't having second thoughts.

"I'm fine," Twilight replied quickly as she gave her rump a little shake. "Please... keep going... oh and you can... um, play with my butt with your paws some more if you want."

Seeing Twilight start to blush again, Dogg smirked and did what she asked. Gripping her ass tighter with his paws, Dogg moved her buttcheeks back and forth in a steady massaging motion. His actions earned him a soft sigh from Twilight and another one as he began to move more of his erection into her ass. As it continued to move in, Twilight tensed up but did her best to stay relaxed for him. Thanks to him moving slow and steady, Twilight felt little to no pain... that was until Twilight felt the bulb in Dogg's penis start to swell.

"Oh gods, here it comes," Twilight whispered to herself as she readied her body to feel that swelling bulb.

Though he wasn't quite as much in as he needed to be for the knotting to take place, Dogg wanted to make sure his princess's fetish would be fulfilled. With a low grunt and a buck of his hips, Dogg pushed enough of his penis in so that all the area that would swell would be inside of Twilight. As he pushed, Twilight let out a small grunt of her own, and, biting her lower lip as the engorged penis started to swell more, she stifled a moan as she felt the inside of her puckered pony pecker stretching in order to accommodate its new friend.

"A-ah, it’s... bigger than I thought it would be," Twilight spoke quietly as the penis stopped expanding inside of her, leaving her with a full feeling. "How does it feel for you?"

"If I maybe vulgar for the moment... your ass feels magnificent, my princess," Dogg spoke to her as he looked down at her ass and was surprised she was able to take his knot without too much pain.

Twilight's eyes went wide for a second, but she realized she was being complimented and simply let out a small chuckle. Of course, the chuckle only lasted for a second before Dogg started to press his body into hers. For a second she was wondering what he was doing, but as he started to lean down into her, Twilight relaxed as both their coats met and Dogg grabbed her front hooves with his paws.

"As much as I would to play with your butt, my princess," Dogg started to say as he jostled his hips and got himself ready to properly fuck her ass. "I feel it would be easier if I did you like this."

Twilight had no objections; the close feeling from her servant and the beating from his heart against her back soothed and calmed her mind and only seemed to make her more horny in the process. In an effort to show her affection for his actions, Twilight waited for Dogg to position his head above hers, and making sure to not accidentally stab him with her horn, she rubbed her mane against his chin.

"Mhm," Dogg groaned with pleasure as his body tingled with desire at the soothing touch of his princess. "I take it you have no objections then."

"I have none... Ah!" Twilight replied as she started to feel the erection move again inside of her.

As Dogg began to thrust into her, Twilight couldn't help but enjoy the feeling of the big bulb moving inside of her. Even as she felt his hips smack against her rump and heard the bed under her starting to gently creak from the motion, Twilight closed her eyes and rested her head against her pillow. As she did, Dogg just looked on as he continued to briskly fuck her. With Twilight looking away, Dogg couldn't help but smirk at the situation. A lowly servant like him, on top of a princess of Equestria and actually providing her pleasure just from plowing her ass. He couldn't help but believe his luck but knew he still had to conduct himself properly. Even when having sex, Dogg stayed civil, and unlike most of his uncultured brethren, he didn't slobber all over the place when engaging in intercourse. All he did was grit his teeth and be forever thankful he was the chosen servant out of all everyone who applied.

"Mhm, that feels good," Twilight spoke with a mixture of a sigh and a moan as she looked up from her pillow.

Dogg didn't answer, instead he just gripped her front hooves tighter with his paws and thrusted harder into her. The action was rewarded with a moan, and then another, and then another, until Twilight's voice played in tune with Dogg's thrust. He didn't go fast like he wanted to. No, he wanted to prolong it, make his princess enjoy every second that she could. He loved hearing her little ooh's and aah's constantly, and that told him he was doing it right. If the ooh's and aah's didn't tell him he was doing a good job, it was the expression Twilight was starting to show on her face. He could see her purple face starting to redden at the cheeks and periodically when Twilight let out a moan, her tongue rolled out of her mouth for a second before she quickly tucked it back in. Eventually the process became foolhardy for her and simply let her tongue hang out as she continued to get dicked. What started as an innocent face quickly evolved into an expression of pure ecstasy for Twilight. She couldn't help but grow louder with her moans and Dogg couldn't help but thrust faster as she did.

"Oooohh, this is the best thing ever," Twilight moaned out in a very girlish tone as the bed started to creak louder under them thanks to Dogg's increasingly hard thrusts. As the thrusts became harder, the headboard of the bed was starting to loudly bang against the wall, showing just how hard she was taking it. She didn't care for the banging though, considering Spike was out for the day and the only other resident in her home was her pet owl. Part of her ended up feeling bad that she was becoming loud enough that he would awake from his slumber.

Of course the more perverted part of herself didn't really care.

No, she was starting to become too lost in the increasing pleasure she was feeling. She could feel the constant slamming of her ass starting to burn and she could hear Dogg grunting and groaning with very satisfying thrust he delivered. She loved it, she loved every part of it, especially that swelling knot inside of her. Nearly a lifelong fetish was finally being properly fulfilled, something that toys couldn't provide her.

Feral.

Bestrial.

Exotic.

Erotic.

Her swirling and bookish mind couldn't help but think of simple words for the feeling she was experiencing. Yet, there was one feeling Twilight was starting to develop more and more as the sex continued on. She wanted more. Even with the constant slapping of Dogg’s lengthy erection fucking her ass senselessly, she had other holes that wanted tending to. Part of her was starting to wish she had more servants to service her. Maybe she could request a griffon servant, have him lay under her while he plowed her other hole aimlessly. She could even request a dragon and see just how much of its cock would fit in her mouth. She was starting to want… no, crave it all. She wanted to be like her mentor and teacher that was able to enjoy harems and such back in the old days of Equestria. Part of her wished she was born back then, if only to enjoy such for one night. She wanted to sink her depravity, enjoy every waking second she could, and then after it was done… well, she would sink even further into it.

Sadly she couldn’t. All she had was the present, and all she had was one servant. But one servant was enough. It was all she needed right now and for a long time.

“Oh gods, you’re doing very well!” Twilight moaned out to Dogg as she could hear him growling from the intensity of the sex.

He gave no verbal response, but instead Dogg pushed his back feet harder into the bed and moved his right paw up to the headboard as a means to brace himself. With his body more steady, Dogg forced himself a few more inches up the bed and for a few seconds he made sure his whole length was buried inside of her.

As Twilight felt that little extra bit of length go in, she couldn’t help but let her eyes go wide and her mind go blank. She could swear she felt Dogg’s erection starting to grow again, and she could hear his growls becoming lower and more feral. He was close, but thankfully Twilight was closer.

Of course she didn’t want to take the chance of being left out of the afterglow with him.

Quickly lighting up her horn, Twilight knew a bit more stimulation was needed and focused her magic like a soft blanket on her vagina. She didn’t rub gently though, no, she wasted no time and rubbed as hard and as fast as her mind would allow and her body could handle. Once she began to rub herself furiously, the room seemed to grow hotter than it already was. On top of her moans, Dogg’s groans, the banging of the headboard, and the constant smacking of her ass, Twilight could feel a burning sensation in her rear growing to the point she was ready to burst. She knew what that was and wasted no time in telling Dogg what was coming.

“Almost there… just a bit more… Don’t f-finish yet!” she ordered as she felt her body starting to tighten up.

Dogg obeyed, just like he always did, and as he heard Twilight’s voice starting to crack, he knew what was coming next.

“Ah… ah… A-ah! Ahhhhh!” Twilight cried out as she felt her release starting to happen.

Doing her best in order to prolong her orgasm for those few precious seconds, Twilight bit her lip and fidgeted her back legs out of instinct. Sadly it did naught, and as she came from the rough anal pounding she was taking, Twilight felt everything in her body nearly come to a halt. Finally she felt that twitch, that spasm and sudden feeling she always felt when she achieved orgasm. Forcing her body to keep going, she kept rubbing herself with her magic as her cum started to flow from her and dribble either into her magic blanket or onto the sheets below. Nothing could stop the spasms her body was giving off, and even Dogg had to slow down as everything seemed to tighten around his rigid cock. Still he kept going, and even as Twilight’s orgasm started to quiet down, his was just starting to come up.

As he felt the surge of cum starting to build and swell inside of him, the only real thought that crossed Dogg’s mind was were to aim his spunk when he came. Sure he could have easily left his throbbing erection inside of Twilight’s butt, but… he simply opted for getting ready to pull out at the last second and caking that glorious pony ass he just fucked in a nice layer of white cum. Sure he would have preferred to leave it in and empty everything he had into her, but his job as a caring servant told him otherwise and the knowledge of cleaning spunk out of one’s private parts was never a fun task. He would save her the trouble of cleaning up her sore lady parts and with that, he gave his erection a very hard tug. He knew he could pull it out, thanks to her being a pony.

“Ahh!” Twilight screamed as the sudden feeling of no longer being stuffed by a dog’s penis ran through her body and was quickly replaced with a sudden emptiness that made her wish he hadn’t removed it. Thanks to it being so sudden, the act made her spell come to a halt and the aura around her horn fizzle away.

Once out, Dogg stared down at his twitching mass and took a few deep breathes in order to catch his breath. Feeling slobber starting to run down his chin, he moved his paws off their respective spots and wiped his chin before he put one onto his shaft and quickly stroked it. The stroking didn’t last long, and after a dozen vigorous paw motions, Dogg aimed his penis at Twilight’s ass and let everything come out.

Letting out stifled grunts as he came, Dogg watched–while Twilight felt–numerous volleys of semen hit her perfectly toned rear. One spurt, two spurts, four spurts, seven spurts, and finally it stopped at that number. Though only the first three spurts coated her ass, along with a small portion of her back thanks to the first intense volley, the last four sadly dribbled to the bed below, giving Dogg a friendly reminder that he would be changing the linens before the night ended. Even with that slight annoyance in mind, both started to slowly descend into a wondrous afterglow. For Dogg, it was a sweet release that was needed much more than he thought, and for Twilight the feeling of the hot sticky spunk coating her rear was a perfect sign that her servant enjoyed himself.

“Mhmmm, that was amazing, Dogg,” Twilight cooed as she looked over her shoulder and saw him fall back to sit on the bed.

“Did I provide satisfactory results, my princess?” Dogg asked, his breathing labored from the intense fuck session.

“Very much so,” Twilight spoke with a sigh as she snuggled her head into her pillow. “Oh, I want one more thing from you.”

Dogg cocked an eyebrow.

“Come cuddle with me for a bit. Wouldn’t feel right if we just had sex and I sent you off,” Twilight told him as she tapped the bed right beside her.

“As you wish, my princess,” Dogg replied in a calm manner, but in truth he was happy to engage in cuddling with her. “Wait, uhh… don’t you want to clean yourself up first?”

“Well,” Twilight started started to say as she could still feel the sticky seed on her butt. “I plan to shower in the morning, but I guess I should at least wipe myself down.”

Looking around her room for a second, Twilight wondered what she could use to clean herself that was rather disposable. Sadly no such object was in sight, and quickly lighting up her horn, she decided to to use one of her blankets.

“Could you move off the bed for a second?” Twilight asked as she focused her magic on the top blanket and got ready to pull it off.

Nodding in return, Dogg pulled himself off the bed and watched as Twilight brought the sheet to her rump and began to try and collect any of the sticky residue. Thankfully after a few hard scrubs and a little persistence, Twilight’s rear was nearly cum free. With most of the cum off her, save for a few parts where her fur was already starting to clump, Twilight let out a content sigh.

“There we go,” she said quietly as she tossed the blanket to the floor and turned her attention back to Dogg. “Now… can we cuddle?”

Standing for a few more seconds, Dogg waited until his spent penis crawled back into its sheath. Once in, he had gave the dirty blanket a quick glance before he turned his vision back to Twilight. Not wanting to deny her, he had no problem moving over the covers, and once he was in position he laid himself down beside her.

“Will you stay with me until I sleep?” Twilight asked as she turned her body to face him, before wrapping her hooves around his neck and drawing him close.

“If that is what you wish, my princess,” Dogg replied but quickly found Twilight giving him a sour look.

“You know you could just call me Twilight, right? You don’t always have to be so formal with me,” she said to him before she snuggled herself back into his chest.

“Very well my pri- I have no problem following that order, Twilight,” Dogg replied.

Though it wasn’t quite what she wanted, Twilight was happy with the response, and wanting to rest her tired eyes, she closed them. As she did, Dogg quietly looked forward and smiled.

“Hmm, a mutt like me fucking a princess,” Dogg thought quietly to himself. “Looks like I’m finally moving up in the world."
