>You are Anon, professional dude guy and "ambassador" to the human race.
>You're not sure what's going on back home, and the memory of your appearance in Equestria is fuzzy.
>The last thing you heard was something along the lines of "Resistance is pointless".
>Whatever that means.
>Right now, you are hanging out with Celestia at her summer home on the west coast.
>Inhaling the scent of the seaside, you stretch your arms behind your head, relaxing deeper into the lounge chair.
"I gotta say Tia, this is really nice. Thank you for letting me join you!"
>"It is of no consequence, Anonymous. I was glad to have company."
>Celestia relaxes in a chair next to you, enjoying the same scents, sights and tastes you were.
>She finishes her sentence with a sweet, loving smile, one that you have seen time and time again.
>You used to think it was merely a façade, but you soon came to realize that smile is as genuine as it can be.
>Honestly, you can't help but smile back.
>"Anon, dear..could you do me a favor?"
>Celestia calmly asks you.
"Of course, Celly. What is it?"
>"Could you...give me a massage?"
>It caught you a little off guard, a rather strange request, but not an unwelcome one.
"Sure. I don't see why not!"
>Slowly, you sit up and stretch, enjoying the sensation of your muscles pulling and joints popping.
>Swinging your legs over, you stand up and move a few steps over to where Celestia was sitting.
>Channelling your inner Slav, you crouch next to her and ask
"Alright, where do I start?"
>You glance over Celestia's beautiful equine form. She is unlike any other creature on this world, even unique to her sister.
>She rolls over and lays on her belly, stretching her wings and allowing them to hang loosely off of the side of the chair.
>"I'd love if you could start at my back."
>You take a nearby bottle of lotion and apply some to your hands, rubbing it into your palms.
>Gingerly placing your hands between her two wings, you begin pressing into her supple flesh, enjoying the feel of her soft fur and silky skin.
>Pressing deeper, you can feel her flight muscles. Just grazing them sends jolts through your limbs. The woman simply radiates power through her very form.
>You're aware that the wings can be considered erogenous zones, so you carefully avoid-
>Ha ha, what bullshit. You don't know anything about pastel horses.
>Tracing a muscle under her wing, you find a point of great tension.
>Wow, that must be sore. Eager to help your friend feel better, you begin firmly massaging away at the tense fibers.
>Celestia sharply inhales and raises her head in surprise.
"Oh, I'm sorry, was that too rough?"
>You notice that her wings are beginning to stiffen slightly. You must have triggered a nerve!
>"N-no. I was just surprised. It felt very nice."
>Celestia isn't usually polysyllabic, but her speech complexity just took a bit of a nosedive.
"Should I keep going?"
>She seems to ponder the question for a moment, an almost...guilty look on her face.
"Celestia, this is no trouble at all. I'll do anything you want."
>Her wings jolt, subtly so, but noticeable regardless.
>Interesting.
>"P-please, continue."
>You move to her right wing, gently but firmly pressing your fingers into the muscle, determined to relieve her stress.
>Eventually, you move on to her other wing, giving it the same treatment.
>Her wings are now limp, and the Alabaster Alicorn has a dopey smile on her face.
>You return to her back, coming up to her shoulders, pressing your thumbs deep into her and moving in small, slow circles.
>She gives a shaky sigh, an affirmation of your good work.
>Continuing on, you move up to her neck, using your fingers to gingerly work the muscles there.
>A deep, long moan escapes her throat.
>"Oh... oh Anon.."
>A wave of pleasure wracks your unprepared body, Celestia's gorgeous voice echoing still through your mind.
>Holy shit, that was hot.
>Celestia seems surprised with herself, suddenly glancing up at you, wide-eyed and blushing.
>You however, look positively entranced, sporting a blush of near-lethal intensity.
>Her expression slowly changes.
>It comes to what you can only describe and 'lustful and mischievous'.
>"That caught your attention, did it?"
>You find it impossible to respond, because Celestia is now brushing her tail over your entire body, wrapping around your face and neck.
>Celestia rolls onto her back, wings splayed outwards, all while she stares into your eyes with purpose.
>"Keep massaging."
>That was not a request. That was a command.
>Under normal circumstances, you would be inclined to rebel, a natural human response.
>But here, you are totally under her power. You're not really sure why.
>So, you comply. You rub at her chest, unsure of where to go and what to do.
>"Unnh.."
>She gasps and moans at your ministrations, leaving you speechless.
>"Lower."
>Oh dear.
>Again, you comply.
>You slowly trace your hands downwards, until you come to her belly.
>You gently rub her, careful not to hurt her.
>In your motion, you brush across something.
>It left a wet mark on your hand....
>Moving your eyes lower still, you see it.
>Slightly unsheathed, is Celestia's cock.
>Your jaw drops and eyes widen.
>It's only a couple of inches out of the sheath, but you can already tell...
>Yep. That's a horsecock.
>For a moment, Celestia looks worried, afraid she's turned you off.
>Not that you could tell, however. Your hands were busy slowly gravitating towards it.
>While, you couldn't say that you were gay, but something about this..appendage, really has you.
>You look up at it's owner, a desperate, almost pleading look on your face.
>This having assuaged Celestia's fears, she grins, nodding slowly.
>Using your hands, you push her thick hindlegs apart.
>You crouch down until your face is near her rather large balls.
>You... were never aware of these before.
>Maybe you didn't look hard enough.
>You can see a thin trail of fluid going from underneath her balls down to her mesmerizing ponut.
>Glancing under her sack, you can see...
>Holy crap, it's a pussy.
>Celestia is a hermaphrodite!
>You can feel a short in your brain. A literal fantasy of yours, coming true!
>Biting your lip, you gently blow on her ever-so-slightly exposed cock, trailing your breath down over her balls and underneath them.
>Her eyes roll back, also now biting her lip to suppress a moan.
>Tia's member twitches, and begins to grow in size.
>Your breath quickens and your heart begins to wildly pound in your chest, your erection threatening to break physical boundaries.
>Her penis has grown to full size, resting against her belly at over 1 and half feet long.
>Her balls seem to swell, now appearing larger than grapefruits.
>"Please.. don't keep me waiting."
>The princess's voice cracks, rising to high octaves.
>The massive thing twitches with each beat of her heart, which is steadily growing faster.
>You seize the moment, and rest your hands on her wonderful balls.
>They feel like nothing you've ever felt before. You lightly trace your fingers all over them, brushing over her soft flesh.
>You plant your face between them, deeply inhaling her musk.
>It's incredible. You're getting high off of her.
>You've always thought she was attractive, despite the fact she's essentially a horse.
>Now, your feelings are simply beyond description.
>You open your mouth and suck her scrotum into it, lapping up the subtle sheen of sweat that had collected on them.
>It's becoming difficult to focus, you're being overwhelmed as you lick and suck every inch of her balls.
>Celestia is breathing hard, and your efforts are rewarded with a wink.
>Her eyes are closed, which only leaves one option...
>Fuck year, horse pussy.
>Finally, you move up to her cock, a thick, pulsing vein running along it's side before vanishing just after her medial ring.
>Precum is practically exploding from her tip, thin rivulets of the stuff running down her side and pooling in the chair.
>Extending your tounge, you look up at her.
>She glares at you with passion.
>Pressing your tongue onto her sheath, you slowly
>slowly
>drag it up across her cock. 
>Moving it from side to side, getting as much of it's underside coated as you can before eventually coming to her partially flared tip.
>You take the entire tip in to your mouth, drinking up her pre.
>You can't believe how much there is... you are very literally drinking her precum like one drinks from a bottle.
>You suck, and suck, and suck, and her flow simply refuses to stop.
>Eyes closed, you wrap yourself around her cock as best you can, milking it for all the pre you can get.
>Hands wrapped around her member, you stroke it for all you're worth.
>You are forced to remove it from your mouth however, it threatens to drown you.
>Gulping down what you can, you deeply inhale, drinking in the precious oxygen.
>Ever vigilant, you keep stroking her, increasing in speed.
>You do what you can to lap up the flow of pre as it runs down her cock, but there's just too much for you to even manage at this point.
>Her hips buck upwards, her titanic member rocketing into your throat just as you had placed your mouth over it's tip.
>Even though it's probably beyond you, you keep drinking up that pre.
>However...
>"Anon.. Anon..."
>"It's coming..."
>You pump harder, eager to taste it.
>"I'm...I'm..."
>"CUMMING!"
>Her hips buck up again as her cum explodes into your throat.
>Pump after pump of cum, she fills your stomach.
>You are eventually forced to remove her from your mouth.
>The second you do, she bucks again and a massive stream of cum flies high into the air, quickly splattering down on the both of you.
>Her cock is still in your hands, and her seed continues to squirt from her tip, running down the length of her cock and coating your hands.
>With one final pulse, she finally finishes her climax.
>Celestia's penis is now at half-mast, laying limply on your face and head.
>Your senses are dulled. You are simply lost in an unimaginable sea of pleasure.
>A pearly white sea.
>The princess uses her magic to pull you on top of her, relishing the feeling of her cock between your bellies.
>She is heavily panting, as if she just ran a million mile marathon.
>Despite this, you are pulled into a deep, passionate kiss.
>Completely deprived of any and all control, you throw your arms around her neck, and she does the same with her forelegs.
>Running your hands through her ethereal mane, you fight against Celestia's hot, writhing tongue in a  battle for dominance.
>Her experience plays to her benefit though, as she soon wins, exploring every square nanometer of your mouth with her long tongue.
>Gene Simmons, eat your heart out.
>Her tongue soon finds it's way to your throat.
>How does it even reach that far?!
>It doesn't matter, she is absolutely dominating you.
>She starts moaning, loudly and desperately into your mouth.
>Her member is rapidly hardening again, brushing against your own.
>It seems to have caught her attention as she breaks the kiss, and looks into your eyes.
>Thin strings of her cum arch between your body and hers, nearly drenching the two of you.
>She laps it up, licking all of the cum off of you as she can.
>You wind up getting thrown to the floor, the soft carpeted deck vibrating thanks to your rough entrance.
>She keeps licking, getting every last single inch of your chest.
>But, she is met with resistance when she meets your shorts.
>In a flash of light, she vaporizes them.
>Well, shit.
>Now, though, she's staring at your cock.
>And she looks hungry.
>She seems to remember your earlier tease, and gently blows air across it.
>Holy fucking shit, her breath is electric. The air softly billowing around your cock and balls stimulates you in a way you didn't think possible.
>The Sun Princess can control herself no longer, and she practically lunges at your member, sucking into her mouth with unmatched fervor.
>Your muscles spasm as she wraps her tongue around your cock, flicking it rapidly from side to side hundreds of times per minute, even while she sucks with equivalent force of a black hole.
>Moans escape you, your mind being totally overwhelmed with sensation.
>It isn't long before you erupt into her mouth.
>Celestia cries out wildly with your cock stil in her mouth.
>"Yes! Yes! More!"
>Her wings are flapping, seemingly losing control much as you were.
>It starts to concern you a little.
"Cele-hshash."
>Try that again.
"C-celestia-a! Are you oka-ay?"
>"No I'm not okay!"
>She jumps onto you, driving her forehooves into your shoulders.
>"I'm in FUCKING heat!"
>Her eyes seem.. primal.
>"I know I should have told you... but.. but...."
>"FUCK ME! I WANT YOU TO FUCK ME!"
>She throws herself into a kiss, her legs collapsing and her barrel falling onto you.
>"I WANT YOU TO LOVE ME!"
>She manages to scream it in between her sloppy kisses.
>She forcefully rubs her rock hard cock against yours, her moans growing louder and louder still.
>That is something you can certainly do.
>You roll her over onto her back, summoning the gargantuan strength needed to lift her several hundred pounds of pure pony paradise.
>You lift her balls up to get good look at her.
>Her clit is winking almost faster than the eye can see, her folds reddened with passion and need. 
>You dive in, pressing your lips onto hers, tougue flicking at her button every chance you got.
>Her fluids were sweet and thick, much like her precum.
>While your mouth works on her pussy, you reach up and start to stroke her cock.
>Your efforts are quickly rewarded.
>Celestia screams, her marehood squeezing your tongue as her hips buck upwards.
>Your eyes are currently filled with balls, but you can feel them churning against your face...
>A hot, thick stream of cum splashes against your back and head as it falls on top of you.
>You quickly look up to see her cock shooting cum straight up into the air, a massive amount of the stuff reaching at least 4 feet up.
>Soon, both you and Celestia are absolutely coated in gallons upon gallons of her cum.
>Her cock does not relent this time, however.
>"MORE! MORE!"
>Her voice booms with Royal Canterlot authority, desperate to cum again.
>You get up on your knees, nearly slipping in all of the cum.
>Placing the head of your cock at her flower, you look to her for appro-
>"YES! YES!~ RUT ME! I WANT YOU TO FILL ME!"
>Her magic quickly forces you into her.
>You instantaneously cum, the unbelievable heat of her aching marehood overwhelming what little defenses you have left.
>"Don't you fucking dare stop!"
>Despite your internal protests, you start pumping into her, slowly at first.
>But you quickly pick up speed.
>Her cock is bouncing around in front of you, still thickly coated in streams of her cum.
>You get a good handful, and get to jerking her off.
>Her speech has now totally degraded, she's just moaning and wailing and squealing.
>She cums yet again, a fair bit less of the stuff this time.
>Still, you get a delicious mouthful, and the rest of it falls onto Celestia.
>She even gets a load in her mouth, which she greedily drinks down.
>The squeezing of her pussy again brings you to another climax, your brain beginning to shut down from the sheer overload of pleasure.
>"Just.. just a little more.. almost..."
>What? She wants MORE? Almost what? Is she going to meta-cum or something?
>But, you can't help but oblige.
>You remove yourself from her folds, a difficult thing to do, considering the tremendous force her walls applied to pulling you back in.
>Summoning your strength again, you pull Celly's ass up to your face.
>You drink in the sight of her now frosted ponut, coated in her sexual fluids.
>It's several inches in diameter, significantly larger than other ponies, even bigger than actual horse butts.
>All the better to you, though, as you wrap your lips around it and lap up everything you can.
>You plunge your tounge into her, relishing the bittersweet taste of her black cherry.
>Celestia seems stunned, eyes rolling back into her head.
>You set her back down and place your cock at her now clean entrance.
>She moans. Can't quite make it out, but you assume it means "fuck me".
>And so you do, you slowly press into her, her anus clenching with amazing force.
>But, your determination is stronger, and you break through her wall.
>Her ass can't decide if it wants to push you out or pull you in, because it's trying both at the same time.
>Resisting the powerful urge to succumb, you pound away at her pink ponut, slapping her jiggling ass every few seconds.
>"Almost!"
>Her horn begins to glow, a mysterious golden-ish color you've never seen before.
>You keep fucking her, until, you finally cum inside her ass.
>This pushes her over whatever edge she was on, and she screams, loudly.
>Her scream echoes across the sea, and even through the sky above.
>You are nearly blinded by the flash of light, and look up to see...
>The sun grows in brightness until it becomes a hot pink, but it quickly returns to it's normal color.
>All the while her cock pumps impossible amounts of cum over the two of you.
>She's turned to a fountain of love; she can't stop cumming, more and more of her thick cum exploding from her.
>Eventually, it slows to a trickle, but it doesn't seem to stop entirely.
>You are drained, and you flop to her side, landing in the massive puddle, almost pile, of cum with a lewd splat.
>Celestia curls up next to you, resting a hoof  on your cum-soaked chest.
> "ahluvyu."
>The words are barely formed, rushed together in an attempt to function through her solar orgasm.
"I love you too."
>Is all you can manage to say before you pass out.
