Celestia laid down on her towel, colored in various hues to match the dye of her well maintained hair. The sun glowed with a comfortable warmth today, perfect for an afternoon at the beach. Letting her arms freely spread wide, the princess's body was on display in broad daylight. Constrained only by a white bikini top, her breasts sat large and plump atop her chest. The thong she wore did little to conceal her smooth, luscious thighs that trailed into her shapely calves. In spite of her thick, curvy bust and hips, her waist remained curiously dainty. Her figure was one that she fought hard to conceal in formal attire, but on her vacation days, everyone would notice. In spite of how hard they tried to pretend not to, that included her royal guards. And her dear little sister, for that matter.

Unsurprisingly, Luna was rather more guarded about catching some sun in the public. Nevermind that the princesses did reserve this strip of the coast solely for themselves for the day. After laying out a dark towel patterned with constellations, the younger sister sat on it with a delicate manner only fitting for a proper princess. Compared to Celestia's, her swimsuit could have been from the last millenium. Though it still clung to her petite body, it was nonetheless a conservative one piece suit that covered nearly everything but her limbs. Her body was nowhere near as eye-grabbing as her sister's, but at the same time it hadn't had as many years to develop. Her breasts were by no means small, but were dwarfed by Celestia's. Luna's hips were slim, her legs long, and all of it lacking the sheer curvaceousness that Celestia possessed. The younger sister tried her best not to be jealous, because after all these things came with age. But even so, she couldn't help but feel that she wanted a body like that too. It was only natural that Luna sat straight up and curled her knees in towards her body, hugging them close.

"Luna, you're never going to get a tan like that. You need to lie back, relax, and," Celestia paused when she realized what her sister was wearing. Oh no, that wasn't going to do at all. Celestia put her hands on her sister's shoulders, rubbing them between her fingers. Luna didn't seem to respond to the massage, but that was normal. "We're on vacation to loosen, so you should try your best to loosen up. Nobody is going to love a princess who can't even enjoy her own day off."

"We are not entirely comfortable in such a situation," Luna said just a little bit too loudly. Luckily only the guards were there to hear, and they were used to her lack of control over her volume. "The sunlight bears rather brightly upon our eyes, and we find it moderately inappropriately to be dressed so scant before our own subjects.' To be fair, a one piece was revealing compared to Luna's daily attire, but that wasn't the point. Celestia could feel the tenseness in her sister's muscles. The elder sister ran her fingers through Luna's dark hair, silky and illustrious as always.

"Listen, at least you can try to minimize your tan lines. You'll look absolutely silly if everyone can see where the straps of your bathing suit went while you're wearing a royal gown." Without asking for permission, Celestia pulled the straps of Luna's bathing suits off of her shoulders. Though it barely revealed anything that was not already exposed. Luna squeaked in surprise and did her best to cover up her naked skin.

"Sister!" she scolded in a tongue she never took up with Celestia. "We do not think disrobing in front of the royal guards constitutes proper royal court behavior!" Luna's hands fumbled with the straps, trying to throw them back on top of her shoulders but failing. Celestia couldn't help but laugh at the site of her sister's inability to redress herself in public. The entire situation, humiliating as it was, forced a blush into Luna's cheeks. Was it really her fault that she was uncomfortable with showing some skin in public, even if nobody was around? Well, there technically were other people around...

"You're never going to be a proper princess with an attitude like this." Celestia was still giggling at Luna's antics, though now her thoughts were rapidly becoming more mischevious. She took each of Luna's hands into her own and moved them away from Luna's shoulders. "A proper princess needs to know when and how to show some skin, especially if she wants to attract the right prince." Luna's milky white skin was shining in the sun now. Her face only flushed a deeper shade of red. "I used to be shy about my body too, but I got used to it. The royal guards are very good practice. They're very professional."

"What dost thou mean, professional?" Luna cocked an eyebrow, genuinely confused by her older sister's implications. Celestia answered only by smiling and standing up, her fully developed body on display. The elder sister threw her hair over her shoulder as she sauntered over to the nearest guard. Hands clasped behind her back, she puffed her chest out, pushing her plump breasts into the gaze of her subordinate.

"See? Mister Ferrous here wouldn't blink twice at me, no matter what I did. Isn't that right, Ferrous?" Celestia shook her body from side to side, allowing her mounds to jiggle. Of course, Celestia knew that Ferrous Tip was new to the ranks, which is precisely why she invited him along. Beneath his helmet, she could see the faintest of movements in his pupils. A twitch of the lips, the littlest bit of sweat trickling from his forehead. He was falling for it, like she knew he would, because honestly who wouldn't? She was fully aware of the effect she had on most men and even some women. But today was a day for having fun, so Celestia was determined that she and her sister would have fun. "Why don't you try it?" Celestia called out, motioning her sister to come over. She had to admit that she was surprised when Luna obeyed with only the slightest of hesitations.

Clearing her throat, Luna stood in front of Ferrous with a posture that put his to shame. She looked him in the eyes with a glare that bordered on accusation. Just look at our body, we dare you, her stare screamed. Pulling the straps of her swimsuit back up, she attempted to imitate the chest shaking motion Celestia had performed moments ago. Luna knew it was stiff, jerky, and that she lacked the assets to create the same enticement that her sister did. But like Celestia said, this was an exercise, a drill that she could use to warm up to future princes. So far as she could tell, the guard responded to none of her movements, though she was honestly more preoccupied with her own body at the moment. The sound of something dropping in the sand behind her broke her concentration.

"Sister, I think Mister Ferrous dropped something. Could you do him a favor and pick it up for him?" Anything to get out of that humiliating charade. After Luna turned around and bent over to sift through the sand, Celestia's face twisted into a devilish grin. Both she and the guard knew that she had kicked the sand, and there was nothing there to be found. Luna's rear, still a little plump with baby fat, was now staring Ferrous straight in the eyes. Celestia licked her lips and pretended to rub it up and down, her hands hovering just out of contact with Luna's butt. Celestia could see that Ferrous's eyes were fixed on the ribald show before him, and it drove her to grow bolder. She pretended to spank her sister, drew out her tongue to slowly lap away at the air. The suggestions she was planting in the guard's head were certainly taking an effect. His feet were shifting in the sand, obviously trying to deal with some sort of discomfort near his legs. While she had her hand with her third and fourth fingers stuck up like talons and her tongue licking away at the air in front of her fingers, Luna stood up with a report.

"Dear sister, we could not divine anything beneath the sands," she nearly said before spotting her sister's obscene gesture. "May we pose inquiry as to what sort of gesture you are producing?"

"Oh this? Uh," Celestia responded, not even bothering to roll her tongue back into her head. "This is the hand signals the royal guard was working on. I was testing Mister Ferrous here if he remembered what this meant." Watching Ferrous sweat again was tickling Celestia's insides. Whatever the "signal" meant, he would certainly have to perform right in front of the pair of princesses. In an instant, a gleam of wickedness flashed in her eyes. The male guard had no time to react in horror at her next words. "Pants down, private!" she ordered, barely able to keep a straight face. Luna couldn't see, but Celestia's face was the perfect mix of "You'd better do it" and "Yes, this is really happening."

Celestia wasn't disappointed when his trousers hit the sand. As specified, there was no underwear, and as expected, he stood only half at attention. Being inspected by a pair of princesses could wrack a man's nerves, after all. What did catch her off guard was her sister's reaction. Rather than some kind of stifled shy blush, Luna instead leaned in to investigate closely. The younger sister let out a low hum, as if she were inspecting an animal at the zoo.

"Is this what the people would refer to as a 'penis,' Mister Ferrous?" She was down on her knees now, handling his half-hard member none too gently. Her hands flipped it this way and that, examining it from all sides. The spectacle was comedically awkward, and Celestia had to bite her lip to stop herself from breaking out in laughter. "Come now, we expect a punctual answer when we directly address a subordinate."

"Y-y-yes, ma'am!" Ferrous stuttered out. Simply processing words in his head was hard enough right now, much less trying to think unsexy thoughts to keep himself from accidentally slapping the younger princess upside the face. As much as Luna's mechanical handling between his legs was helping him stay limp, the show Celestia was putting on, rubbing her breasts together and pinching her nipples through the thin fabric of her bikini top, was overpowering him. The captain had informed him exactly what being a guard on a royal beach trip actually entailed, but he didn't think he'd be the first victim. And the last thing he wanted was to prematurely expire before the real fun started.

"Interesting. We have never seen a live specimen with our own eyes before." She released like the thing from her iron grip, allowing it to dangle back where it belonged. "We were not aware that this 'penis' could assume a semi-solid state. Our royal texts indicated no such thing."

"That's simply because you're not handling it correctly," Celestia responded. Ferrous swallowed some air, knowing that this was the do or die moment. He could feel the blood draining from his head and rushing to his groin. A small gasp from Luna confirmed that he was indeed rising to the task. Celestia sauntered over to him, her hips swaying the entire time. As her fingers gave his newly hard meat a few test pumps, she whispered into his ear, "Don't be afraid to take all the roughness out on me. Just be gentle on my sister, got it?"

Before he knew it, Ferrous could feel his entire length swallowed down by the older princess. It was a shock that rippled through his body, but a pleasurable one this time, unlike the rough handling of Luna. He looked down to see Celestia, her magnificently dyed hair covering one eye, and the other eye winking back at him. She was wasting no time at all in deepthroating him. As her head moved back, he could see her enormous tits swinging in the air, pressed together by her arms at her side. Remembering the princess's words, Ferrous threw caution to the wind. Each of his hands grabbed fistfuls of Celestia's hair as he began thrusting in and out of her mouth, taking full control of the situation. He could hear the sounds of her gagging every time he pushed himself all the way in. The way her tongue rolled about on the underside of his cock made in groan in pleasure, a reaction that made Celestia smile.

Seeing the young guard take control so quickly startled Celestia, but she was not going to argue. Being forced into a submissive position was such a rare occurrence, it developed its own kind of thrill by now. She tried her best to reward Ferrous by giving him extra treatment with her tongue and hands, but his cock was pounding at her throat so hard, it was difficult to do anything that required the least bit of focus. She resigned to stroking her breasts as his hot meat punished her mouth. She started faking a gag for show, to encourage the young man to go even harder. When his crotch met her face, she held herself there, determined to hold him down for as long as she could. She moaned as she shook her head, swallowing and massaging his cock with her esophagus. Ferrous responded in kind, holding her head in place, pinning her nose between his legs, where she could smell his damp musk. As her deepthroat continued, she could feel the shaking in his legs that warned of an incoming orgasm. Determined to not yet finish the fun, her hand pinched the base of his manhood, denying him any release. As she removed his length from her mouth, she gave him another wink to tell him the fun was only beginning.

"And that dear sister," Celestia said between a few coughs of having her throat worked so hard, "is how you handle a man's cock." Luna's eyes were wide in fascination, her mind unable to process exactly what she had scene. It looked violent, yet it was fun? How was that possible?

"Our observations tell us that such an act was painful for you. How does one grow accustomed to such acts?" Luna cocked an eyebrow, genuinely puzzled at the act.

"I've had a lot of practice. The trick is that you have to start off slow." The older sister motioned for the younger sister to kneel by her side. Luna obeyed without question. Grabbing the still hard shaft, Celestia pointed it at her sister's face. The one eyed beast was still pulsing in Celestia's grip, staring right into Luna's eyes. Ferrous's deep, controlled breath made it look like a heaving monster to the teenaged princess. Luna, unsure what to do, hesitated as her hand reached for it. "Let's start with the basics," Celestia interrupted. "Kiss it, like you would a fellow noble's cheek."

That familiar comparison made Luna a bit more comfortable. With elegant poise, her dark lips pecked his rod. It certainly felt like skin to her, though it had a distinctly different taste and smell. Luna felt like the odor should have offended her, but she found herself drawn to it. It made her feel some kind of foreign excitement that she had not experienced before. She wasn't sure what it was, but when she saw Celestia motioning for her to do it again, she didn't think twice about it. This time, her tongue flicked over his tip, running against the slit that had been staring at her moments ago. The teenager could still taste some of her sister's spittle, along with something else that was quite salty. The flavor was quite enjoyable to her taste buds. When Celestia pulled the shaft up, exposing its underside, and licked upwards at the air, Luna figured out exactly what she meant in no time at all.

As Luna's inexperienced tongue slowly lavished its way up his penis, Ferrous found himself struggling to stay under control. He was young and brash, so when Celestia gave him free reign over her, that was easy. To play gentle with the younger princess required far more self control. His hands waved aimlessly in the air, resisting the urge to grab onto Luna's raven hair and pull without mercy. A few moments later, he felt something soft and supple beneath his fingers tips. When his eyes opened, he saw Celestia's amazonian form standing a fair bit taller than himself, and his hands on her heaving mounds. The shock over touching Princess Celestia's tits was nothing compared to the relief that he could keep his hands busy. Her breasts were far too large to be contained by his palms, but that didn't stop him from rubbing and caressing them. Through the thin fabric of her bikini, there was not a hint of sag, just supple flesh for him to play with. As her nipples poked through, he nipped them with his teeth, happy to please his monarch. As he felt a warm mouth envelop the head of his cock, his teeth pinched and pulled at Celestia's large nipples, eliciting a throaty moan from her.

As Celestia looked down at her faithful guard, she thought about how badly she wanted him and the rest of the royal guard to ravage her right then and there. With a modicum of willpower, she resigned to smothering the young guard's face in her bosom, allowing him an up close and personal look at the envy of Equestria. No, she scheduled today for Luna's sake. Of course, she could have fun too - not that she wasn't already - but teaching Luna came first. Pulling Ferrous's head off of her tits, she gave him another whisper as she licked his ear. "Be patient, I promise you won't regret it." She slithered back down to her knees, making sure to give the young man a sultry grin as she descended. Back at his nether regions, Luna had about a third of his length engulfed in her mouth, with salivia dribbling off her chin in a most unroyal manner. Seeing Celestia's face again, she pulled the shaft out of her mouth with a sloppy pop, spit still dangling from her lips and his tip.

"We do not understand how our sister is able to accept the entire organ in her mouth," Luna said with puzzle in her voice. "Even half of the penis tasks us to capacity." She was about to take Ferrous back into her mouth when Celestia signaled for her to pause.

"Baby steps, Luna. I'm quite proud that you can do that much on your first time." Celestia rolled her eyes in glee, remembering her first romp with a royal guard. "For now, use your hands to cover what your mouth can't And don't neglect these boys," she instructed as her fingers tickled his ballsack. "One more thing," she added as she like the corona around his head. "Try using your teeth just a little bit around there. He'll love it."

The sensation of the sloppy, energetic blowjob combined with the new feeling of having his testicles massaged made Ferrous's head want to explode. He thanks the heavens when Celestia came back up to him, bathing him in affection with her soft breasts. When Luna's teeth scraped against the most sensitive part of his cock, he jolted with pleasure and fought with every nerve not to give in then and there. Every part of his body was burning hot, and he needed to release it all right now. When he heard the words "Go ahead, cut loose" whispered into his ears, he didn't need to be told twice. All the heat and pressure flushed out of his body and through his manhood, flooding the teenaged princess's mouth. More than once he groaned each princess's name, as his arms wrapped around Celestia for support. He could hear coughing and gagging, but nothing would stop his warm juices from spilling out now. It took several volleys of pleasure for him to finish, and when he opened his eyes he was nearly horrified.

Princess Luna was sitting back, absolutely drenched. Semen not only ran down the corners of her mouth, but covered her face and made a mess of her bathing suit. Though she looked surprised and confused now, it would no doubt be mere seconds before she collected her senses and turned furious. Ferrous looked up to Celestia, hoping for some respite, but the older princess was simply transfixed on the sight too. As Luna got back on her knees, her tongue flicked over her lips. To everyone's surprise, she smiled in delight.

"Thy flavor is delectable!" Luna's fingers swiped up more of the goo to be cleaned off by her tongue. "We are pleased with this activity and wish to repeat it as much as possible!" Ferrous felt his heart skip a beat at those words. Not many girls would be happy at such a sudden mess. "Tell us sister, what other manners may we enjoy the company of the royal guards?" Celestia felt giddy at those words, more than happy to play the matchmaker for the day.

"I believe Mister Ferrous here would like you to get on your hands and knees. Isn't that right?" She turned to the younger man. Naturally, he couldn't think straight enough to respond, but she filled in for him anyway. "If you'd do him that favor, I'm sure he'd be grateful. As the younger sister rolled over into the proper position, Ferrous needed no instruction to get on his own knees. Celestia handled her sister's rear, moving aside the fabric that covered her private areas. The guard licked his lips as he admired the dark, trimmed hair neatly outlining her labia. As he lined up his already slick penis to her glistening slit, Celestia grabbed him by the shaft and jerked upwards. With a yelp of surprise, he looked up at the princess. She was shaking her head, but with mischief instead of disapproval. She reguided his aim a little higher as she spread Luna's buttocks apart, revealing a puckered, pink bud. Ferrous gulped, unsure whether or not this was some kind of horrible, horrible prank, but Celestia's expression told him that this was really happening.

Luna dug her fingers into the sand, thinking she was ready for the next step. She couldn't have been more wrong as she felt something pressing against the wrong hole. Protests began to fill the air, but they were useless as two pairs of powerful hands held her hips in place. Her sister's dainty fingers ran through Luna's hair, as Celestia's voice soothed her and told her to relax. As she tried to make the muscles in her body obey, her face still scrunched up in anticipation. She could feel the bulbous tip push past his sphincter, a painful stretching. Her ass felt like it was on fire, and she only managed to hold in the scream by stuffing a towel into her mouth and biting down as hard as she could. Even with just the tip penetrating her, it was uncomfortable. She thanked the stars that the young man stopped moving, allowing her time to adjust. As she sat motionless, trying to endure, something wet and warm made itself present between her legs. Gently, it glid over her vaginal lips, stopping to penetrate her slightly or peck at her thighs. When Luna opened her eyes, she could see her sister's full figured body underneath her.

Celestia had no qualms will making her dear sister feel as comfortable as possible. The elder sister didn't have the same luxury the first time she experienced anal penetration, and there was no reason Luna had to suffer the same. She had one hand gripped firmly around the base of the guard's cock to signal him to pause while she eased Luna's nerves. The teenager's pussy was immaculate, perfectly maintained. Celestia simply resolved to keep it that way, licking away and traces of juices that would leak out. Her free hand rubbed at the insides of Luna's thighs, trying to ease away the tension. Absentmindedly, her nose dove into her sister's womanhood, inhaling all her fragrances. Her tongue thrust in deeply, wiggling about in all patterns to explore Luna's juicy inner walls. Nothing in the world brought her more joy than pleasing her sister like this, as she could hear whimpers of excitement coming from Luna's mouth. Abandoning her plan to lust, she devoted both hands to spreading the teenage princess's legs, giving herself full access to Luna's privates. Before long, her tongue traced curves and zig-zags across the raven haired girl's bud. Stroking Luna's thighs, Celestia planted kisses and nibbles on her sister's clit, each one met with a squeal from the younger girl.

With the stop signal gone, Ferrous contined to plough forward. His pace was guarded, not wanting to harm the younger girl. Little by little, he pushed forward and halted at any sign of resistance. His hands joined Celestia's in stroking Luna's legs to keep her body at ease. At every pause, he marveled at the sight of Equestia's most beautiful woman eating out her own sister. Had he not orgasmed such a short while ago, he could have shot his load simply at what he was witnessing. Even as slick with cum and saliva as his cock was, Luna's ass was tighter than he could have imagined. The vicelike grip was squeezing him for all he was worth, but he was determined to get himself all the way in, for the princess's sake.

As Luna could feel both ends of her lower regions being assaulted with pleasure, the towel fell from her mouth. Her voice turned to moans, deeper than that of her sister's. Every push of the guard's length sent new waves of pain and pleasure rippling up her spine, which were always joined by the burning euphoria that Celestia would send through her pussy and clit. With a pair of warm organs devoted to servicing her body, Luna couldn't hold her voice down. "More! We demand more!" she shouted, almost loud enough to make her partners cover their ears. On her command, she felt the guard's meat plunge deep inside her. The sensation left her breathless, unable to vocally react to the burst of warmth that rammed inside of her. At the same time, she felt teeth chew ever so gently at her clit. Her eyes rolled back into her head as her partners picked up speed. The man in her rear would pull out, only to slam back into her again, each motion straining her ability not to moan like a whore. Her sister now hand three fingers rolling back and forth inside her, with lips planted on her sensitive button. The gentle suckling from the front was a stark contrast from the rough pounding she was taking from behind. As her anus felt empty and full again for a number of times she couldn't count, her arms gave out and she buried her head between Celestia's own voluptuous thighs.

"W-We are at our peak!" Luna screamed with a shaky voice. Vibrations tumbled through her body as her legs shook and spasmed. She lost her posture and collapsed, smothering Celestia with her gushing slit. Juices squirted out of her and onto her sister's face and her muscles contracted with energy that bordered on violence. The younger girl could smell her sister's arousal even through the thong, driving her orgasm to even higher peaks. Ferrous was thrusting into her faster than ever, desperate to finish the same time she did. The feeling of being ravaged from behind blended in with her orgasm, reducing her to a babbling mess. Her tongue lolled about as she rode it out, feeling a gush of hot fluids fill her rear end. The cock pulled out of her with another pop, as the gooey seed dribbled out of her puckered rear. Her heart threatened to rip itself out of her chest, pounding with unmatched intensity. She rolled over onto another towel, bodily fluids trickling out of all her holes, an expression of mindless ecstacy smeared across her face.

"Did you enjoy yourself, dear sister?" The question was rhetorical of course. Luna didn't seem to be in much of a mind to answer anyone. "That's just the warm-up today. Mister Ferrous isn't going to be done for a while, and there's the rest of the royal guard to attend to." Neither Celestia nor Ferrous could tell if the words were lost on the younger princess or not, but that wasn't important for the time being. Celestia stood up tall, her sister's vaginal fluids still slathered over her face. Licking what she could off, she scooped off the rest and allowed Ferrous a taste. She could tell that he quite liked it himself. "Now then, Mister Ferrous. I want you to tell the captain to get the rest of the guards ready in half an hour at most. And report back to me as soon as you've told him that."

"Princess, shouldn't I be with the guards preparing?" Ferrous asked with a puzzled expression.

"No," Celestia said as she untied her bikini top and rubbed between her legs through her thong. "I need you her as soon as possible to service me, understood?"

Ferrous sprinted off like his life depended on it. Next Chapter: Celestia's Warm Up Estimated time remaining: 11 Minutes
