Beginnings

You wake up to an unfamiliar setting. You don't remember much from last night. All that comes to mind is that you were getting ready for bed when all of a sudden, a blinding flash of light engulfs you. Now you find yourself in a room on a bed that looks like it was made for a giant. On top of that, you are naked. You were about to move when all of a sudden you hear the sound of a doorknob turning. You look towards a pair of giant doors only to see a tall, muscular horse-woman enter the room. She sees you and smiles as she closes the door. You gulped at the sound of a lock moving into place. You open your mouth to speak but you found that you could not. You clear your throat again and tried to speak but, once again, you could not. You looked up to the woman as she chuckled.

"If you are wondering why you can't talk, it's because I placed a silencing spell on you. I don't like it when my pets make noise. Of course, there are exceptions to certain sounds that I do oh so love to hear. I don't need your name because you don't have one. Not anymore at least. You are my pet. Don't worry, I intend to treat you well and you will live like royalty. Behave and you will not be harmed but if you do misbehave, then some "Behavioral control" will be used. Nod if you understand."
You nod your head. Considering your situation, and the massive size of this woman, you had no choice but to nod.

"Good. My name is Celestia. I rule this land with my sister, Luna. You will meet her soon. Now, you are probably wondering what I intend to do to you. In brief, I am going to rut you. Hard."

You feel your body getting hotter and you can feel yourself getting erect. You always had a domination kink and a thing for strong, muscular women. If she wants to play dominatrix, then you will be more than happy to be her pet.
You look up to Celestia and smile. She smiles in response.

"You are eager. Good. I will confess. Your physique is a rarity here in Equestria. Most, if not all of my subjects are muscular demi-gods in physique so a small, petite frame like yours is very difficult to find. With this said, you are a very desirable object."

Celestia moves to the foot of the bed and uses her finger to beckon you closer and you comply. Your heart beating a mile a minute. You reach her and sit down. Despite this, you find yourself at waist level and could see her abs through her tight clothing. You also notice a rather large bulge from her groin area. You look up to meet her gaze.

"On top of that, a lot of the mares here, myself included, possess a stallionhood. This is something that you will get very close to. You are my stress relief and you will be of constant use to me. But enough dallying. I'm getting tired of this waiting and frankly, I want to begin."

With a flash of her horn, Celestia removed all of her clothes. You are now staring at her flaccid member. You guess that it is about 10 inches in length. You couldn't help but stare for what felt like minutes. You had always been curious about this sort of stuff and now an opportunity has presented itself. You feel Celestia put one of her hands onto the back of your head and you look up to her.

"Come on pet. Get to sucking."

You take her cock into your hand and lift it to your lips. You bring her head to your lips and begin licking her. You hear Celestia moan and feel her hand pushing you on. Not wanting to leave your new mistress disappointed, you open your mouth and take her in. Thankfully, she is not that wide in girth so fitting her in your mouth was not a problem. You start to bob your head back and forth repeatedly. After getting into a rhythm, you look up to see that Celestia was breathing heavily. You close your eyes and continue on until a rather naughty idea crosses your mind. You put your hands around and onto Celestias' hips and grabbed them.

"Pet, what are you doing?" Celestia asked with curiousity in her eyes.

You looked Celestia in the eyes as you took a deep breath and pushed yourself, and pulled her towards you, as you deepthroated her cock. You tried not to smile as Celestia gave out a very throaty moan. You let yourself stay put for a few seconds to allow your throat to accommodate her. When you felt satisfied, you begin to pull yourself off her cock when all of a sudden you feel both of her hands grasp your head.

"Now that was unexpected little pet. I think your enjoying this just as much as I am. But now that I know you can throat me, I am going to rut your little throat raw."

She didn't even let you react as she slammed herself back into you. You couldn't help but gag as she started to piston into you. You tried and kept failing to get air into you on her backstrokes as she kept this up. She kept on going for another couple minutes until you hear her breathing becoming more ragged, her thrusts becoming more desperate. By this point, you are a mess. Tears stain your face and spit and pre was running down you chin. After another minute. Celestia forces herself all the way down your throat as she let out torrent after torrent of cum. After a few seconds, you place your hand on her hip and gently patted her. You guess she got the signal because she pulled herself out and stepped back. You immediately began to cough and burp as if about to vomit but it never came.

"Now that is what I call a blowjob. I will admit, I did not think you had it in you." Celestia look as you and laughs. "And you look like an overworked whore. But you are my whore now and we are not even done yet."

You weakly moved yourself onto your knees again only to feel Celestia push you back onto the bed.

"Back to the pillows pet."

You nodded as you pulled yourself back to the pillows. You sighed as you rested your head against them.

"Now, turn yourself onto your stomach and place a pillow under it."

You smiled weakly as you did as told. Once you got the pillow situated, you felt the weight of Celestias' body against yours as she laid on top of you. You assumed this was only half of her body on you as she began to nibble on your ear. You couldn't help but moan.

"You have done well thus far pet so relax. You enjoyed the appetizer so enjoy the main course."

The Sibling

As Celestia continued to nibble your ear, you could feel her starting to grind against you. Essentially hotdogging you, you couldn't help but moan in response as Celestia used her pre to lube up your entrance. For your part, you didn't mind. It felt good knowing that, despite her size, she was gentle and caring enough to take your behavior to notice. You couldn't help but feel safe under her. And the warmth of her body against yours was a bonus to boot.

Eventually, like all good things, Celestia ceased her grinding and just held her body against yours. Celestia had also ceased her nibbling and gave you a peck on the cheek. You began to get confused as Celestia had rolled off of you and was laying at your side. Using her index finger, she lifted your head up a little and smiled.

"I hope you enjoyed my little tease pet. Now I know you would love nothing more than for me to breed you like the little slut you are but you are simply not ready to take my stallionhood in that tight ass of yours. So to remedy this, I have brought my sister to join in. She is smaller than me but you will have a lot of fun with her regardless. She will break you in for me. Luna, would you be a dear?"

Luna? You lifted yourself up just a little to look around but you were put back down as a weight put itself onto your back.

"Would you like to see your other mistress pet?" Celestia asked.

You nodded your head. Celestia used her magic to summon a mirror to your other side and you turned your head to see another muscular mare sitting on your back. To say she was beautiful would be an understatement. She was divine. She was shorter than Celestia but she was just as well built as her. You could also see her erect stallionhood. You wagered it was about 8 inches in total. Give or take. You looked back up to see her eyes meeting yours and you couldn't help but blush. Luna smirked as she took notice. You watched as she moved herself to spooning you and continued the hotdogging that Celestia had removed herself from. You turned your head back to Celestia to see her smiling.

"Is he not a beautiful thing Luna?" Asked Celestia.

"Indeed sister. We thank you for allowing us to share in this. And to break him in no less" replied Luna. Her voice had something of an accent to it but you could not place it.

"Oh sister, I am happy to share my things with you. He is yours just as much as he is mine. I wish I could stay but I have another matter to tend to real quick. I shouldn't be long." Celestia got up from the bed and patted your cheek. "Have fun you two."

The moment Celestia had left, Luna had put you into a chokehold and brought her head to yours as she continued her hotdogging.

"You will find that I will not treat you like my sister does. She likes to be gentle. I like it rough. I will be honest. I love BDSM. And I am ALWAYS the dominant one. Behave and you shall have fun but if you don't than I have some toys that will adjust your behavior. Perhaps you would enjoy it though hmm?" Luna finished off with a soft kiss to the cheek. "Since this IS your first time with an alicorn, I will take it easy. Just as sister intended. And as much as I dislike the flatiron position, it would make this easier on you. So enough wasting time. Let's begin shall we?"

Luna raised herself up a little and used her free hand to press her member against your entrance only to slowly press it forward. Your body had started to tense up as the pressure began to increase. Luna was quick to notice and eased up on her advance.

"Keep breathing toy. And do try to relax. It will be so much easier if you do."

You did as told and focused on your breathing and tried to relax as Luna resumed her insertion.

"I will let you decide on how we do this toy. Tap the bed once if you want me to go slow or twice if you want me to get it over with."

You take a second to decide and had opted to get it over with. You tap the bed twice.

"Very well toy."

Luna quickly covered your mouth as she plunged herself into your tight hole. Your screams were muffled by Luna's hand as her hips connected with your ass. Rather than continuing on, Luna waited until your scream had died down to a whimper. When it did, Luna removed her hand and started nuzzling your face.

"Shhh toy. I will wait until you are ready. Just get used to the feel for now."Luna then moved to kissing and licking the back of your neck. This continued for a good minute until, finally, you wrapped your legs around hers. Luna pulled herself back and spoke.

"Put your hands onto both sides of your head." You did as told and she grabbed your hands. "Just relax and enjoy yourself. This is just a warm up for you"

You grunted in pain as Luna started doing short thrusts, her breathing slow and steady. Eventually, the pain started to subside and in its place, pleasure. You guessed Luna picked up on this as she started moving for longer, harder strokes. A few more minutes passed by and the pain was fully gone and you were now starting to enjoy it and, once again, Luna noticed.

"Are you liking this toy?" You nodded with a smile. "Good, because now we can have some real fun." Luna quickened her pace to the point where she was pistoning in and out of you. You gasped and moaned loudly as Luna began to properly fuck your brains out. As Luna continued to fuck you, you could feel an all to familiar pressure building in your groin and decided to work this out for yourself. Luna had taken notice and grabbed your throat and pulled you to your knees, her hips connecting with you once more.

"You will NOT pleasure yourself toy! If you wish to achieve climax, then you will do it like the breeding mare that you are!" Luna ignighted her horn and you could feel your body tickle. "There. Now you can't cum unless I want you too. Understood?!" You nodded as much as you could despite Luna's grip on your neck.

"Good." Luna pulled out of you and pushed you back down. "Now, onto your side and pull your leg up." Luna pressed yourself to your back as you lifted your leg. Once she was in position, Luna used one hand to keep that leg up and used her other hand to force her member into you once more as you gasped loudly. She then proceeded to jack hammer into you. You moaned loudly until Luna used her hand to pull your head into her direction and pulled you into a deep kiss. You could tell Luna was reaching her end. On top of her pistoning and heavy breathing, the intensity of her kissing was being fueled by desperation alone. Suddenly, Luna broke the kiss and forced you into your original position. She then began to nuzzle and whimper into your neck as she finally reached her end. With one final grunt, she hilted herself into you and tensed up numerous times as she rode out her excitement. With a satisfied sigh, she pulled out and just layed on top of you. You thought she had gone to sleep until she got up and ran her hand over you rump.

"Looks like someone was a virgin. At least you had fun wouldn't you agree Celestia?"

You rolled over onto your back and saw that Celestia was in the room. Sitting in a chair with a cup of tea in her hands. Had she been there this whole time?

"How was he lulu?" Celestia asked.

Luna looked over to you and smiled. "Better than I thought. I think next time I will dress him up though. Maybe a prench maid or cheerleader. And some makeup perhaps. I would love for him to be tied up in a dress. Oh and I just removed that ejaculation prevention spell on him so he can find release whenever you wish."

Celestia smiled. "Thank you Luna. And you can have him whenever he is not with me. Or perhaps even join us on the fun. Now I believe you have night court now."

"Indeed I do sister. I will see you two at breakfast." Luna got to the door and left leaving you and Celestia alone. She smiled at the look of confusion you were giving her.

"I like to watch. It's one of my fetishes. Now it's my turn. Don't worry. I will be gentle. To the pillows and on your back."

The Finale

You sighed as your head hit the pillow. It was nice to rest for a minute and catch your breath. You knew what was going to happen and you were relieved that it was Celestia that would keep you company. It's not that you didn't like Luna's treatment per say but rather how quick it was. You were expecting it to go on for a little bit longer. You guessed that they don't really last as long as a human but the intimacy was certainly nice.

Celestia moved herself onto the bed and laid herself on top of you. Her face inches from yours. You lifted your legs and wrapped them as far as her body would allow and pulled her body closer. Celestia grinned.

"Good boy"

You decided to take a risk and pulled her into a kiss. Rather than protest, she leaned into it and forced her larger tongue into your mouth. You tried to wrestle it with yours but hers was far to big to match. But you still tried anyway. As Celestia moaned and whined, you ran your hands along her chisled body, feeling every bump and ripple. Celestia did not seem to mind one little bit and smiled as she broke the kiss.

"I see your having fun. Lets move on a little bit more hmm."

Celestia moved back in to kiss you some more and you moaned as you felt her hand moving its way down your body. It continued past your groin and you suddenly felt her member against your ass. You braced yourself as she started to move in. Unlike Luna, she slid in with ease. You broke the kiss and gave a high pitched moan as Celestia moved herself into you. Eventually she hilted and began kissing your neck as she started to withdraw almost completely and started to slowly thrust in and out of you. You dug your fingers into her as jolts of elecric pleasure coursed through your body and your moans and whimpers caused Celestia to giggle as you kept wiggling your body in response to her minstrations.

"Looks like I found your prostate. Lets see how long you can last little pet."

With those words said, your fate was sealed. Celestia lifted herself up off of you, using her hands to support herself. She leant down and kissed your nose before picking up her pace and increasing her assault on your prostate. If you weren't on edge before then you certainly are now. You gripped the bed as hard as you could as Celestia continuously increased her pace. Everytime she plunged back in, you felt nothing but pleasure. Unadulterated, full body pleasure. As time went on, you could feel an all to familiar pressure building and it looked like Celestia was not to far behind. You don't know how long she had been at it but she was practically dripping with sweat. Her breathing loud and heavy. You cupped her face with you hands and she looked at you. Absolutely beautiful.

"Almost there huh? Me too. Just, damn, just hold it for a moment longer."

Her quick pace turned into a desperate assault as you both reached your peak. You wrapped your legs around Celestia tightly and brought her into a kiss only for her to pull back. Celestia forced her muzzle into the crook of your neck as she tightly pressed her body into yours and gave out the most throaty growl you have ever heard. You could not hold it back any longer and followed suit. You gripped her body tightly as you gave out a very feminine whine that lasted for a few good seconds. You could feel her throbbing member as she let out spurt after spurt of cum. As you finished your climax, Celestia pulled herself away from you. Her member coming out with a lewd pop. It was odd. You never felt so full in your life.
Celestia looked over to you and laughed in between her panting. She placed her hand onto your now bloated belly and pushed down. You groaned with a dumb smile as all that cum made its way out of you. After a good second, you pulled yourself to Celestia and rested against her. Celestia, having moved herself into a more comfortable position, returned the gesture, pulling you close and tight.

"My my, what a mess we made. I apologize if I was to quick pet. I just really needed this. I promise to take things more slowly next time. As for you, you did very well."

You lifted yourself up to her cheek and kissed it before resting yourself against her. You yawned and hugged her tightly.

"I agree pet. Time for bed. Lay on you side."

You did as told and sighed as you felt the blanket cover you and you smiled as the warmth of Celestias body rested against your back. You shivered as Celestia slowly ran her hand along your hip and upwards until it rested on you chest. You took Celestias hand and rested it onto the bed and let sleep take you.

Celestia's POV

You couldn't help but smile as your new pet silently snored away with a smile on his face. He certainly was adorable and with time, and training, he would be the perfect fuck-toy. And Luna, with her crossdressing ideas, would certainly make for some interesting roleplay. Celestia smiled and planted a kiss on his cheek.

"Im glad I chose you." And with that, Celestia fell asleep.
