Submission

Ruby opened the door to her room with a tired huff as she threw her saddlebags on the floor. Between Twilight's lectures and the seemingly endless amount of nobles trying to court her, she just wanted to get in her bed and sleep the rest of the day away. Or try to at least, the good student in her nagged in her head that her homework must be done before anything else. And the fact she just started her heat cycle didn't help much either. Settling on at least completing Twilight's assignment, she sat down at her desk after collecting her saddlebags and got to work completing her homework. In all honesty, this load was pretty small compared to what she was used to receiving from her mentor, and with a brush of her crimson mane out of her eyes with an off white hoof, she placed her quill back in its designated inkwell at her desk corner. With her homework completed, she decided a well-deserved bath was in place, along with some reading from a book she special ordered labeled Your Mistress and You. This idea, however, was cut short when a knock came from the door. A sigh escaped from Ruby's lips as she left her desk and made her way across the room to the door. Like most rooms in Canterlot castle, her's was more designed as a live in suite than a room; soft cream colored carpet covered the floor of the suite, save for the marble floor in her bathroom. The walls were painted an almost pinkish color, with most of the said walls being covered by photographs of her adopted family, or her marefriend. She smiled at the thought of how interesting her family must seem, Princess Luna together with Nightwind, a dragon from the Dragon Empire, and Octavia Melody acted as parents to her and her little sister, Cynder. A strange herd nonetheless but they were all family and loved each other dearly.

As the teenaged mare opened her door, a small smile made its home on her muzzle at the sight before her. A dark blue Thestral with piercing red eyes and black mane and tail greeted her in a special form of Dragon scale armor. The mares name was Midnight, but in private or among family she was named Jitter, a changeling who was in service of Ruby's father before they came to Equestria. Hopefully giving her best bedroom eyes she offered Midnight a simple wink as she moved out of the way for her mare to enter her room.

"Good evening, Midnight, did you just finish your shift?" She quickly closed the door and made her way next to Midnight, who was walking around as if she was looking for something.

"As a matter of fact, I have," Midnight's commanding yet gentle voice sent a pleasant shiver down her spine. Although she loved her changeling form, she also loved her current form. As Midnight started making her way closer to her desk, Ruby felt a feeling of excitement in the back of her mind when Midnight picked up the book she had been reading for the past month. Her tail gave a slight twitch when she saw the predator gaze from her marefriend after she looked the book over. "What is this?"

"It's... um... a-a book?" Ruby didn't know why she was so nervous, nor why she was getting wet, but the look Midnight was giving her made her arousal start growing.

"I can see that," The guard turned the book cover towards the white mare, "Read it to me." Her nostrils widened as she smelt Ruby's scent, an intricate growing in her mind. Ruby gulped as she looked at the book held in her marefriend's hooves, physically squirming under Midnight's gaze.

"Your Mistress and You: A submissive's guide to pleasing your Mistress and being a submissive." A smile formed on the guard's muzzle as she started getting closer to her prey, greatly emphasizing her hip movements as she circled the teenager. Ruby yelped when she felt her tail forcibly get yanked up, exposing her wet marehood to the cool air. The sound of armor being removed caused Ruby to look back towards Midnight, only to receive a slap to her cutie mark.

"Don't you look at me unless I tell you!" Midnight's commanding tone caused Ruby to quickly face forward again, "You really must be a serious slut in order to be this wet already." Ruby moaned as she felt Midnight's hooves spread her delicate lips open, her warm breath teasing her clit as it winked. "Oh, aren't we sensitive today? I have just the thing to solve your little problem." Ruby dared a quick glance back as her tongue slightly lolled out of her mouth, causing her to receive another slap on her ass. "What did I say about looking at me without permission?"

Ruby timidly answered as she felt Midnight shifting next to her, "Not too, Mistress."

"That's a good filly," Midnight licked one of Ruby's ears before taking it into her mouth, lightly nibbling it and causing Ruby to moan and start panting, "But you're still going to be punished, and when I am done with you..." after taking a long, painfully slow lick from the base of Ruby's neck to her ear, Midnight whispered, "All you'll think about is pleasing your Mistress." The next thing that Ruby knew, her world turned black as something was slipped over her eyes and a gag placed in her mouth. "The safe word is Nightmare."

The next several minutes were just a blur to Ruby, between being shuffled around her room, to the feeling of rope being tied to her in ways her book never explained. The feeling of her ass held high in the air and her pussy exposed for the world to see filled her with a mixed sense of dread and anxiety. The anticipation was killing her inside as well; the gentle tugs of the rope teasing her pussy promising of great pleasures to come, the warm breath of her lover tickling her fur, and the sound of a door opening and closing only increased her anxiety. The deathly silence overtook the room as she knelt. Did Jitter leave the room? Was she all alone? What if someone entered the room and saw her like this? She let out an involuntary moan at her last thought, the idea of a stallion entering her room, seeing her tied up and exposed, her white flanks high in the air and her soaked pussy ready to take his cock. After what felt like an eternity, she heard the door open and close again.

She held her breath as the sounds of hooves walking across the floor got closer and closer to her location, coming to a stop shortly after. A gasp escaped her lips as a warm wet appendage made contact just below her dock, slowly moving down towards her puckered asshole. A moan escaped Ruby as Jitter worked her tongue around her ass, occasionally pushing it in and filling her as much as her tongue could fill. Her panting soon turned to a sharp intake of air as the tongue was replaced by a cool piece of metal slowly being pushed into her ass. As the intruding object got deeper and deeper, Ruby let out a pained whimper as her inexperienced ass was robbed of its virginity. A gentle hoof found its way to her cutie mark, and gentle words started filling her ears as Jitter nibbled the tips. Hearing the voice of her lover helped relax Ruby as she felt the rest of the butt plug slide in her ass, making her feel fuller than she had ever felt before. Her thoughts were shifted from her back to her front as the gag in her mouth was removed, a thin trail of saliva connecting it to her mouth for a few seconds more before breaking. Not a moment later the cinnamony smell of Jitter’s sex filled her nostrils as it shoved itself onto her muzzle.

“"Please your Mistress.” That was the only command Ruby needed as she started licking Jitter’s pussy. Only for it to be pulled away a second later, "What do you say?”

"Yes, MistRESS!” Ruby's anal walls clenched uncontrollably as the plug in her ass was pulled free from its tight prison. Ruby was left panting afterward, her ass opening and closing as it started closing itself again. Ruby ran through her mind what she answered wrong and quickly came up with a new response. “"Thank you, Mistress!”

"For?” The plug stationed itself at the entrance to Ruby's again and pressure was slowly being added to it. Ruby whimpered and wiggled her ass in an attempt to feel full again. It clicked what she needed to say when the pressure left.

“Thank you, Mistress, for letting me pleasure you!” A loud moan escaped her lips as her ass was yet again filled with the metal plug and her tongue tasting the sweet nectar of Jitter’s marehood. Up, down, and all around her tongue left no spot unexplored as she lapped at the snatch before her, the sound of Jitter moaning egged her on as she worked harder to make her Marefriend cum, and with the mare in front of hers moans getting louder and her pussy gradually tightening, she didn't have long.

Jitter shoved back hard as she came, forcing Ruby's muzzle to enter her pussy and drink up her fluids, which the white Thestral enthusiastically licked and swallowed as much as her mouth can hold. As Jitter pulled away, Ruby took a deep breath of much-needed air, which got cut short as the gag was reinserted into her mouth. Her Mistress licked Ruby's muzzle, kissing and cooing as she made her way down her body. The aching in Ruby's limbs from being tied for so long pales in comparison to the burning inferno that raged inside her pussy. Jitter broke away from the tied mare for what felt like several minutes, but the wait ended when two hooves were mounted over her hips, and a very big, blunt, and hot something pressed against her soaked marehood. Although blindfolded, she looked back in confusion as the stallionhood started to penetrate her; she wasn't a virgin by any means, but whatever style Jitter was wearing felt so life like that she swore it was real. As the tip of the phallus lay inside her, Ruby could feel it pulse occasionally, earning Jitter a moan mixed with an inquiring whimper.

“"A quick lesson for my little pet,” purred Jitter as she teased one of Ruby's ears, “In order to fit in pony society, Changelings have the ability to change their genders based on their circumstances. For example, if our targeted pony were to be a male, we'd change into a female pony to extract said males love, and as for female targets...” Jitter wiggled her hips, causing the cock in Ruby to tease her, “you'll find that my little friend here not only looks and feels like a stallion’s, but is as potent and virile as one. And you my pet are a sexy, fertile, and all mine!” As Jitter was speaking she forced her cock farther and farther into the Thestral, until the medial ring was kissing her entrance. Jitter leaned closer to Ruby's ear as she spoke next, “And you are going to bare me beautiful foals!” Ruby cried out as Jitter jilted herself deep into Ruby's pussy, thrusting long and hard as Ruby drooled onto the floor, eyes rolling to the back of her head. She didn't have a care in the world; she was in heat, she was getting rutted, everything felt right, even the cock currently pounding away at her pussy getting thicker, and the butt plug in her ass filled her with blissful pleasure. Ruby knew she wasn't going to last very long, the tingling sensation building in her loins told her so, but the question was how long could she hold it; she dare not cum without Mistress’s permission. Unfortunately, though, one particular thrust that bulls eyed her cervix caused her to lock up, back arched and head locked back as her orgasm exploded over Jitter’s cock. The added lubrication and Ruby's pussy milking Jitter’s cock was too much for the Changeling as she thruster as far into her pet as far as she could go. Rope after thick, creamy rope of cum filled her pussy until a small little bulge appeared where her womb was; not highly noticeable at a glance, but a long look would definitely show.

Ruby's vision returned as her blindfold slide off, and the secure, familiar feeling of Jitter’s magic lifting her in the air, brought her attention the gorgeous Changeling in front of her. After a brief second, the two locked lips as their tongues danced inside Ruby's mouth. But this was short lived as Ruby began to fall into blissful slumber, full of cum, and heat satisfied, a gentle smile plaguing her face.

Ruby stared at the strip held in front of her, a feeling of excitement, fear, and nausea swimming in her body as she looked at the plus sign for the tenth time that day. She was pregnant, with Jitter’s foal, and she had yet figured out how to not only tell her but her herd as well. She should at least tell Jitter first, but then how would her parents think about her not telling them first? A knock on her door tore her away from her thoughts as she went to open it, revealing Jitter in her disguise. With a sheepish smile, and a feeling in her heart telling her everything would be alright, she let her marefriend in and sat her on the couch.
