**The Sex Dungeon Of The Princesses

Part One: The Sexening**

~kisses!

Celestia had just finished making her way down a long, winding staircase, deep in the underbelly of Canterlot castle. These areas had been strictly off limits to everypony besides herself and her sister for quite some time, and should any poor soul happened to have gotten curious and wandered off into this forbidden zone, they were quickly apprehended and placed in the sisters' private dungeon.

The princess fumbled with a ring of keys contained neatly within her aura as she came off the final step, at last finding the barred, wooden door on the right. Luckily, she had three new 'victims', several royal guards who were taking their jobs a little too seriously and had taken some liberties they were not allowed. She had actually been hoping for something like this for quite some time, and had no intention of keeping them locked up for long. With what she had in mind, they might actually want to get caught again.

"Ho hum," she sighed to herself, finally picking up the last key with her magic, "A princess' work is never finished, I suppose."

She placed the key in its slot, turned it, and promptly lurched the heavy door open. It made a dull, creaking noise, suddenly alerting the three stallions she had bound to the wall and coincidentally waking them up. The dungeon itself was built of cold, rugged stone, circular, and about ten feet or so in diameter, making it very... intimate.

Hanging from the ceiling by a long chain, swung a low, singular lantern, containing within it a full candlestick. Celestia used a light, yellow wisp of her magic to set its tip ablaze, swiftly illuminating the small room with a soft, vermilion glow.

"Oh, this is going to be so much fun!" she chirped.

The three stallion unicorns, colored white, grey, and black respectively, were all being held up by two shackles latched around their forelegs, binding them to the circular wall. They were forced to remain in this quasi-standing position, clearly exposing their nether regions for the princess to freely admire and gawk at. She licked her lips as she glanced around at all of them, and they were finally coming to.

"P-princess," stammered the black male, forcing his eyes to lazily open, "W-what did we do? Please let us go."

Celestia turned to her left and closed in on him, coming to about eye-level and meeting his blue-eyed gaze. Struggling against his shackles proved useless, but he was able to stand up tall in an attempt to stand imposingly over her. Little did he know, it was all pointless.

"Aww..." she whined, "You mean... you don't want to be in my dungeon?"

"B-but--" he tried to defend himself, but was swiftly cut off by Celestia advancing and driving her muzzle into his.

He fought back for a split-second, yet quickly found the feeling in his legs nearly give out. The pressure on his body seemed to melt away, and the exhaustion he had felt before evacuated his frame. Celestia had relieved herself of her golden jewelry, for she knew far in advance that she was going to get a little messy tonight, and used this opportunity to place one of her delicate hooves under his now unsheathed and rapidly swelling member and lightly pull up on it. When she gave it a light stroke, she felt it fatten in her grip almost instantly, causing him to softly moan into her mouth. She allowed his brief stint of excitement run its course, and suddenly broke away.

After their long kiss was over, she gave him a warm, yet twisted smile, showing him that she was eagerly anticipating something. She removed her hoof from his now swollen cock as well.

"W-wait," he pleaded.

"Oh, don't you worry," she gave him a playful wink, "You're going to be Luna's toy for the night, not mine. She prefers dark meat anyway, and would probably kill me if I got to you before she did. She just likes it when I get everypony 'ready to go' before she arrives. My sister is very much a mare of action."

Giving a cursory glance to the two stallions just behind her, she cocked her head and smiled at them as well, now slowly advancing upon them. They grey male at her left causally stood up higher, as did the white one at his right shortly after. Celestia noted to herself that they all seemed healthy and muscular enough for her sister's tastes, as well as for her own. She absolutely adored how they all had the same lovely, blue eyes.

"Princess," said the grey stallion; his voice was sharp like a knife, "We're sorry, truly. We beg for your forgiveness, and that you release us. We swear on our lives to never tell another soul about this."

Celestia simply smirked at him. "Of course I'm going to release you, silly. Nopony would ever believe you anyway, so there's no point in keeping you three down here longer than is needed."

"B-but, why are we bound to this wall then?" he stammered.

"To help you stand up, of course," she said gleefully, "That'll make our little orgy so much more enjoyable for everyone, don't you agree? Besides, if you three behave for my sister and I, we might even let you off early so you can enjoy this just as much as we will. This is going to be so much fun!"

Without so much as another word, she casually positioned herself between the two, her head eye-level with the grey stallion's unsheathed phallus, and her ass-end toward the other white male.

While she licked her lips once again at the growing sex organ in front of her, she unconsciously moved her flowing, multi-colored tail to the side, proudly presenting herself and her loins to the stallion at her behind. Though he remained quiet, he couldn't help but stare with his mouth agape at her fleshy folds. With his hooves still bound to the stone wall, he found it somewhat difficult to turn his body toward her, but the subtle, hypnotic swaying of her hips coaxed him to advance. He'd give anything to mount her right now; this was something primal, a purely instinctual feeling.

Celestia could hear the movement of shackles and chains behind her, and slowly eased her supple ass a few steps backward, yet her mouth remained in reaching distance of the grey stallion in front. She lowered her head, chanced one last, seductive glance up at the stallion's blue eyes, and gradually descended upon him. His phallus had thickened enough to support its own weight, giving Celestia no trouble in practically swallowing it whole. She was sure to be gentle with him, but always liked to test her limits on the first go-around with new partners.

He let out a sharp gasp of pure ecstasy when her luscious lips wrapped around him and plunged down, giving a light thrust of his hips to assist her. Engorging itself even faster than before, his cock became drenched in Celestia's hot saliva, letting rivers of it flow down to his hanging testicles.

"Mmm..." she moaned lightly, savoring his taste.

It was about this time she felt something thick and weighty come to rest on her lower labia, which were slowly becoming saturated due to her own excitement. She casually released the gradually fattening cock from her mouth, leaving the stallion in front begging for more, and turned her head to the one at her behind. He appeared hesitant, not sure of himself if this was the right thing to do. So, she decided to give him a slight reprieve, and with a prompt wave of her horn, used her magic to dispel the seal on his shackles. Once his chains had fallen away and he was finally free from the wall, he was able to easily place his forelegs over Celestia's back end and prop himself up, giving himself plenty of leverage for the act he was about to commit. He began to greedily eye her rump and the length of her back, rubbing her sun-shaped cutie marks with his hooves.

"Go ahead," she whispered to him with a wink, "I'm all yours, big boy."

Taking the hint, he licked his lips and began working his hips up and down, running the full length of his silvery member along her swollen vaginal lips, coating it with the natural lubricant her body was producing. Once completely lined with her juices, his cock, nearly a foot and a half in length, stood at the ready outside her drenched entrance.

Not wanting to give him any performance anxiety -it would be less fun that way- she swiftly turned back to the grey stallion and quietly enveloped his still engorged length within her warm lips, causing his abdomen to twitch by an uncontrollable reaction. She let out a long sigh of relief through her nostrils when she finally felt her soaking, vaginal lips being slowly split apart by a sizable mass. Instinctively, she sucked on the rigid cock in her mouth even more forcefully, almost using it as leverage to keep her body in place, as she was about to be bombarded from both ends.

For the first time that evening, she heard the stallion at her back finally speak, and he sounded most pleased the further he leaned his weight into her.

"Ohhhhfuuucckk..." he moaned breathily; his voice was deep and heavy, "Princess..."

He drilled into her, further and further, taking much more liberty with her body than she anticipated he would. Another primal urge caused him to lower his head and inhale deeply of the scent coming off of her back, driving his nostrils into her soft, white coat. He gave another brief thrust with his hips, forcing Celestia to suddenly lean forward and promptly fill out her mouth with even more throbbing, stallion cock.

"Mmmm!!" she loudly moaned.

Her eyes fluttered open for only an instant, and she was able to see the black stallion off to the side, completely ready to go. His member was fully erect and palpitating, and she could tell watching this scene unfold before him was pure torture on his soul. He clearly would've given anything just to be able to rub one out, just to have some kind of stimulation, just to trade places with the white stallion who had the widest grin plastered over his smug face.

Luna came to the door on the right at last and eyed it curiously, wondering for a moment why it was shut. She tried the handle with her magic and was quite relieved to see it was unlocked, though she heard a strange sound coming from inside the stone room as she opened it. It sounded almost as if her sister was choking on something, fighting for her very life.

She flung the door open much as her sister had earlier, and her features immediately stiffened with utter dread... and jealousy.

Her sister was indeed choking, on a stallion's fat cock no less, and she was being stiffly rutted from behind by another, equally tall, white male unicorn. Her cheeks were stained red by some intensely heated pleasure, and the stench of hot sex filled the small dungeon. Every time the male at her behind gave a thrust, her sister would lunge forward and cause herself to gag. All three ponies were working back and forth methodically, like some twistedly efficient sex machine, and Celestia couldn't be happier for it.

It took her nearly half a minute to notice that her sister had just walked in on them, but when she suddenly stopped, Luna felt all eyes fall on her. The stallions were allowed a second of respite to catch their breath. Celestia was sweating, yet held no shame in her eyes. In fact, she looked quite happy to see her sister.

"Mmm-mmph!" she mumbled through a mouthful of cock, waving to her sister. She casually released the grey stallion's length from her mouth and gave a quick, hearty swallow of his salty pre-ejaculate. "Hello, Luna. I did as you asked and got them all ready to go."

"But, Tia..." Luna quietly pouted, "How could you start without me? This almost never happens to us, and you already knew I wanted one for myself!"

"But I did leave one for you!" Celestia defended, pointing a quick hoof to the black stallion. "He's all ready to go too, just as you had requested. I haven't so much as touched him. Look! He's so anxious, Luna!"

"W-wait a second," the grey stallion weakly muttered, "B-but you kissed—"

He was promptly cut off by Celestia's icy glare, quite thankful her sister had stopped watching. "If you so much as speak another word—" she hissed sharply, "—I'll have you beheaded."

Luna's attention turned to the black stallion in question, as her sister went back to picking up where her 'machine' left off, and her eyes flickered in the lantern's light in complete shock. He was indeed just as she had requested, with a coat as black as pitch, and very well endowed no less. Their eyes immediately made a firm connection, causing the black stallion to press his back into the cold wall. He was shrewdly embarrassed that the princess -the one he secretly cared for the most- had to see him so helpless and exposed, but there was little he could do now. The skin around his black phallus had been stretched nearly to its limit, and there would be no bringing it down with Luna's arrival.

With her soulful mane trailing behind her, she playfully smirked up at his blue eyes and made her approach, biting her lower lip only once. She stopped when she reached him and leaned upward so that she could easily whisper in his ear. She wanted these words to be private.

"I was wondering when you'd get a little curious and wander on down here," she spoke quietly.

"I-I'm terribly regretful, Princess Luna," he whispered back to her.

"Oh, don't be," she teased him, "You have no idea how long I've had to go on without getting a good 'fuck' around here. I'm sure my sister hasn't been too kind to you either, forcing you to watch those other two have all the fun. What do you say? Do you want to help me show them up? I think we could do a little better than they could."

"W-what do you mean?" he muttered.

She swiftly placed a delicate hoof on his engorged member, giving it a playful stroke. He let out a breathy gasp for air in quick response, just as she had hoped would happen.

"I 'mean' that I'll let you free from those chains and shackles, if you agree to give me the best fuck I've ever received in my entire life. I want to make my sister jealous, and I'm sure that you want to make your two friends over there jealous as well," she gave him a quick peck on the cheek. "So, what do you say? Would you care to rut me senseless, big boy? I think the two of us can make this whole exchange a little more...

interesting."

"Princess Luna," he winced as she tugged on him again, "I'll do anything you ask of me. I'll do whatever you say. Just... please, I beg of you... let me mount you now. My body can't take it anymore..."

She smiled again and gave him a deep kiss on the lips, enjoying the strong contraction of his firm, chiseled jaw. She calmly pulled away, leaving a thin trail of saliva connecting their muzzles together, and looked into his blue eyes once more.

"Good boy," she whispered happily, causing him to smile in return.

Not yet releasing him, she lowered her head and ran the wetness of her tongue up and down the length of his shaft a few times. He practically threw his head back against the wall, making a dull thud noise, finally getting the stimulation he had so desperately craved. Once she had him coated with a thin layer of her saliva, she gave him one last assuring wink, and began to turn her rear toward him. She flicked her tail off in one direction, submissively presenting herself, anxiously waiting to be rutted senseless. With a small burst of magic from her horn, she heard the shackles unhinge somewhere behind her, and glanced at her sister whom still had a mouthful of stallion cock. She quickly noted the white stallion at the back also, only able to press in about two thirds of his full length, which caused the princess of the night to lightly giggle.

"Hey, Tia," she called to her sister; Celestia opened her eyes for a second, giving Luna only a fleeting glance. "I see you're having some trouble taking that dick in your rear. Let us show you how it's truly done."

She collapsed onto her front and raised her hind end proudly into the air. The black stallion had placed his hooves over her crescent moon-shaped cutie marks and positioned his throbbing phallus, still dripping with her warm saliva, directly against her quivering labia. Her cheeks curled into a twisted smile as she looked at Celestia, widening in pure ecstasy as her stallion bore his full weight upon her, and only grew wider as she felt her cunt nearly split open thanks to his hefty member.

"Oh fuck..." she whimpered, glad to see her sister was watching, "Yesssss..."

She placed her muzzle into the crook of her foreleg to stifle her moaning, but it didn't quell the sound much. Her slave clutched the sides of her luscious hips to keep her from fidgeting, and reeled her in. He promised to give her the best fuck of her life, and he had every intention of doing just that, but he would need her to work in sync with his body to achieve it.

As he began instinctively thrusting his hips, he could feel her inner walls begin to relax and stretch, allowing him to go in further each time. He was admittedly the most well-endowed out of the three stallions present, as Celestia had planned this far in advance, for she knew her sister could tolerate much more 'real' sexual punishment at one time than she ever could. Every time they had been given a chance to partake in group sexual activities, Luna had always been able to take the most stallion cock in one sitting, a feat she was most proud of. Although, Celestia always had a much higher tolerance for swallowing load after load of semen, something she was just as equally proud for. They could both tell this would be a night where they would truly test one another and see just whom would break first.

"Mmmm!" Celestia moaned angrily; trying to show how much she detested Luna's competitive behavior.

Her sister kept panting lightly to herself after every hammering she received from the black stallion behind her. A small puddle of cum and pre-ejaculate was starting to form beneath the two lovers.

"''Huff'... I'm sure you're... 'huff'... getting a little tired... 'huff'... Tia!" her sister retorted.

Celestia simply rolled her eyes at the suggestion. "Mmmmph!"

"Bullshit, Tia!" Luna argued, watching her sister force herself to gag even further on the grey stallion's cock, "We both know... 'huff' ... that I can do this ALL night."

Perhaps taking the challenge a little too seriously, Celestia used her magic to pull the white stallion in even further, stretching her inner cavity to its maximum. She winced slightly by the small twinge of pain, as she was not quite used to this as Luna, but she remained firm. The stallion at her behind also seemed to enjoy the move as well.

In response, Luna leaned her ass back into her thrusting, stallion slave, giving him the much needed cooperation he desired. He peered down at her rump, noticing her other cavity just a few inches higher where her labia were widely spread, and an idea came to mind. It might have been a terrible one, or perhaps it was just what he needed to help his favorite princess win her little 'challenge'.

He just hoped that Luna wouldn't order him to be executed the next day.
