You are found by Twilight Sparkle and get shuttled off to Canterlot for diplomatic/scientific reasons. On the day of your Royal Audience, the princesses are laying on their thrones, looking very regal. Such crown. Luna seems to be in charge of xeno affairs.
"We welcome thee, Anonymous the human, to our world and land."
You bow, because it seems appropriate.
"I thank you, Princess Luna, Princess Celestia. It is a good land."
We shall call it... This Land. Luna sits up, revealing a fully erect horse dong.
"Thou mayest kiss the royal scepter."
...
"No."
"Forgive us, for we know our ways and forms art strange, but wilt thou not participate in this most venerable traditions? It hath ever been thus, betwixt royal and emissary."
You turn to Celestia.
"Is she being serious?"
She sits up, revealing a similar set of equipment.
"The practice has fallen into disuse, but there are those such as yourself for whom we permit the honor."
Your gaze switches back and forth the two princesses, trying to gauge their seriousness. Luna beckons towards you.
"No doubt this is the first time thou hast seen such appendages, but we assure thee, they hath no sinister aspect."
This has gone on long enough.
"Princess, I know exactly what you have. It's a dick. I should know, I have one too. There is no way I am kissing your dick as some weird erotic formal greeting."
Luna is taken aback. Celestia is blushing. Moonbutt stammers out,
"W-wilt thou r-reveal thy claim to roy- royalty?"
...
"You want to see my dick?"
You are privileged to witness the slow ascent of twin wing-boners. Celestia's lips part, and she breathes more heavily.
"Please, Anonymous."
You were not prepared for how throaty Sunbutt's voice was. You glance around, confirming that this private audience is in fact, private. You unbutton your pants, then slowly pull down the zipper. Luna is completely focused on your crotch, absently brushing a forehoof against her shaft. The pants come down, and you step out of them. Your boxers can't hide the fact that your flag is at full mast. You gently tug your boxers down, letting the head catch the waistband. With a final pull, you reveal your bouncing dick. Both of the Princesses follow the motion with their eyes, wings utterly stiff. Luna glances at Celestia, who nods.
"Thou hast proven thy claim. Shall we greet one another as tradition dictates?"
It takes you a moment to get what she means. It takes you a moment longer to decide, but you think it's worth it.
"Shall I go first, as a stranger to this court?"
Celestia nods graciously.
"That seems proper."
You approach Moonbutt. She leans back, to ease your access. You sit among the cushions of her throne, and stretch out a trembling hand.
It's warmer than you expected. Luna lets out a little gasp at the sensation of your hand on her cock. Such a feminine sound, perhaps this will be easier than you thought. You lower your mouth to her dark blue glans, hovering a tiny distance above it. You feel Luna twitch in your hand, like she just barely resisted doing a pelvic thrust. You make eye contact, and are pleased to see her heavily flustered, her eyes half-lidded. Keeping eye contact, you gently kiss her "royal scepter". She closes her eyes, her face tense, and she shudders.
"We th-thank thee. Twas most exquis-"
You aren't done. They riled you up, and you are going to do this proper. You take the head into your mouth, stroking her shaft with your hand. She groans, and rests a hoof on your shoulder, rubbing erratic circles on your back. You bring your tongue into play, swirling and probing at the edges. With one hand, you stroke her cock, slow and steady, and with the other, you fondle her balls. Her moans grow loader. One of your fingers slides behind her ballsack, to find hidden depths that are much more to your liking. Luna lets out a surprised squeak that turns in to a high pitched cry of climax. Hot semen blasts into your mouth, and you jerk back instinctively. It gets all over your shirt, and a little onto your legs. Your spelunking hand comes back wet with a different substance, and you just sit there, processing what exactly you just did. Luna levitates some towels out from behind the throne for you. You suspect this isn't the first time they were used to clean up this stuff, although possible the first time off of a guest. Luna lets out a deep breath.
"Thy ministrations art divine, fair Anonymous. I fear I shall be inadequate in returning the favor."
As you wipe the last of the cum off your face, you see she is seriously worried.
"We shall see. You are not without gifts of your own, after all."
You get up, and walk to the other throne. Celestia is waiting patiently, watching you with a hunger that belies her gentle bearing. As you climb into the throne, you spot a dark spot in the cushions under her marehood.
"Enjoy the show?"
Celestia smiles ruefully.
"I do believe the maids will have their work cut out for them."
Celestia leans back, but you have a better idea.
"Why don't you lay down on your back? It should make things easier all around."
"As you wish."
She lies back, her rear scooting forward until she is partially laying in her own wet spot. She spreads her back legs wide, her forelegs folded up against her chest. You get a good view of both sets of genitals, and hear a brief flapping. You turn to see Luna approach, hanging back outside the throne. Celestia averts her gaze, blushing quite noticeably.
"Whenever you're ready."
You straddle her hind right leg, and place your hands high up on her chest, below her hooves. You slowly descend down her soft, furry belly, making small furrows in the coat. As you get closer to her groin, her breathing speeds up. You bring your hands together, cupping her balls and lifting them gently. You bring your face down and let her shaft brush your cheek. Celestia's forelegs twitch, and her breathing hitches.
You release her balls, and slip one hand below to stroke her lower lips. You are rewarded with a surprisingly cute moan. With your other hand, you press her cock onto her belly, rolling it back and forth. You slip a finger into her wet depths, eliciting a sharp gasp. You pull it out, then lower your mouth to her opening. Your tongue brushes against her pussylips, sampling a flavor that you can only described as vanilla and some sort of berry. You drag the tip of your tongue up, painting a line along the middle of her sack, then up the rod. You bestow her glans with many kisses, each one gaining you a twitch or a moan. You ease your lower half back, letting your cock come to rest against the taut muscles of her thigh. Your left hand resumes the duties of sounding out Celestia's hidden depths, while your right strokes her shaft furiously. You bring her glans into your mouth with each up stroke, then let the down stroke pop it out of your mouth. Her groans and moans become louder and longer.
"Say my name."
"Anonymous~"
You rub your cock against her leg, and pulse your fingers in and out of her slit.
"Again."
"Anonymous!"
You remove your mouth from pleasuring her, focusing on stroking her dick even faster.
"Louder, Celestia."
She bucks wildly against your hand.
"Anonymoouuussssssss!"
Her cry echoes in the chamber, as fluid gushes from her pussy, and great ropes of cum spurt out onto her heaving chest. In a bit of mischief, you pump her cock at the nearby Luna, who jerks back at the sudden impact of cum on her face. A few last spasms fall onto the cushions, and Celestia is spent. She lays back limply, catching her breath.
"I must agree with my sister, I don't think I can match your performance. That was, that was intense."
Luna pulls more towels from their hiding places, and cleans up herself and Celestia while the latter recovers. Sunbutt levitates herself upright, and stands shakily.
"You've upheld your side of the agreement. It's our turn now."
Luna nudges her sister.
"Thou art not yet recovered, Sister. Let us take the first attempt."
Celestia settles back among her cushions.
"Very well."
Luna presses her nose against your chest, gently pushing you to the back of the throne. You have a magnificent view of the Gluteus Solaris from here. Then Luna lays down, putting her head at waist level to you, and you find your gaze being drawn to her large teal eyes. She gazes back, leaning forward and letting your cock slide up her snout. The sensation of her short, soft fur is exquisite on your shaft. Her tongue slips out and gets a good lick of your balls, the sudden wet warmth startling you somewhat. Then she pulls back.
She leans forward, this time letting your cock prod against the underside of her jaw, pressing her throat against your head. Luna pulls her head down, and your stiffy springs out from under her chin, rises, then falls to bounce off her nose. She giggles, brushing her mane back with a hoof. Her mouth opens, tongue delicately questing for your meat.
You stare deeply into her eyes as she guides your entire length into her mouth. She starts to suck on your cock, and you pet her head, giving her little nudges. Luna soon gets the idea, and bobs her head, tasting every inch of your manhood with her supple tongue. She develops a rhythm, going up and down your shaft, making little moans. Luna increases the pace, and you've stopped petting her entirely. Instead, you grab the back of her head and her horn at the base and thrust into her mouth, relishing the look of surprise on her face. She relinquishes herself to your efforts, eyes rolling back in pleasure. You thrust and thrust, and your dick vibrates with her muffled moans. It's too much, you moan,
"Oh, Luna!"
You let loose in her mouth, clutching her head to your groin. Her eyes widen, then go half-lidded as her tongue undulates to swallow every last drop of cum. You pull out, sucked clean and sated. Luna licks her lips, and smiles shyly.
"Did we do well, Anonymous?"
You ruffle her starry mane.
"You did very well, Luna. Very well indeed."
The cushions rustle, and Celestia joins Luna in laying before you. She takes a look at your softening erection and pouts.
"We can't have that."
Celestia engulfs your member in her mouth and you gasp at the sudden stimulation. She pulls back, and your cock falls, still soft, but very warm and pleasant. Luna scoots off to the side to give her sister more room to play. Celestia laps up your dick again, then sucks on it as she pulls back. When it comes out of her mouth with a pop, she asks,
"Tell me, Anonymous, what do you intend to do here in Equestria?"
Then it's back in her mouth, giving you time to answer.
"I hadn't really thought about it much."
Pop.
"It seems to me that you could contribute a great deal culturally."
This is really feeling good. You brush her bangs out of the way as she sucks on your cock.
"Culturally? Like, stories and music?"
Pop.
"That's right. You have a whole world of stories no one else has heard."
You can feel your member start to harden in her mouth.
"I don't know how well I would do, I'm hardly the best storyteller, let alone trying to reproduce my world's music."
Pop.
"Hmmmm. I'm starting to see some progress. It sounds like you could use a patron, until you get the hang of things."
This time she does a little flourish with her tongue, and you are almost ready for action.
"That would be nice. I take it you're offering?"
Pop.
"That'll do nicely. And yes, of you'll have me."
Celestia stands up, and smiles at your conflicted expression. On one hand, this is an excellent job offer. On the other hand, you wish she would go back to doing what she was doing. But you are an adult, so you do the sensible thing.
"I would love to have you as my patron."
The fact that you would see more of these crazy sisters is no small factor in your choice. Celestia grins, and gives you a quick kiss.
"Glad to hear it. Shall we continue?"
Awww Yisssss
"Oh yes, please do!"
She turns around, which momentarily confuses you, but then you are faced with the most glorious rump you have ever seen.
"Go ahead and touch it~"
You stretch shaking hands out and grasp those luscious flanks, the perfect consistency between firm and plump. You knead those cheeks, squishing and pulling and pushing and loving every low moan coming from this mare. Then she starts backing up, until you are pressed against the wall.
"What are-"
She lowers her rear from where it was pressed against your stomach, down, coating your dick in her marecum. She keeps going, and your cock slides in the valley of her ass, then exits out the top, tangling in her tail. Then she rises, until her slit is pressed against your vertically pinned shaft. She looks over her shoulder at you, a sultry expression on her face.
"Penetrate me."
You quickly comply, pushing her forward a little to give you room to maneuver. You pull down your cock, and line it up with her winking gap. It plunges in, warmth and euphoria radiating from your pelvis to the rest of your body. You pump it in and out, your rear hitting the wall on the out, your thighs slapping her ass on the in. You take a firm hold on her hips and increase your pace. You don't even have to prompt her.
"Ah~ Ah-anonymous! Nnnngg, harder, oh!"
You can see Luna stroking herself with both hooves at the sight, and it turns you on even more.
"Aaahhh! Yes! Please, pull my tail!"
You move a hand from her hip to the base of her tail, using it to force more of you into her.
"Anon! Oh, yes, Anon!"
This is pushing you over the edge.
"Celestia! I'm going to cum!"
Her ass suddenly presses you back into the wall, and you give an involuntary yank on her tail. She lets out a high pitched cry as her walls tighten and pulse around your cock. You let go of her tail and seize her hips for one last time, and shoot deep inside her. Your dick spasms, filling her with your semen, awash in her own fluids. You both slowly sink to the ground, unwilling to separate. As you lie there, you idle stroke her flanks.
"This has to be one of the best moments in my life."
Celestia smiles at you.
"Mine as well, though I do have hopes for the future."
Luna stands over the two of you, scowling.
"Anonymous, we demand a best moment of our lives as well!"
An anon's work is never done.
