>"It's very much like an itch I can't scratch, Anonymous."
"Well don't you worry, once we get to that waterfall there is going to be a lot of scratching, believe me," you laugh.
>It's been three weeks of hiking to this magical sex pool that will give Celestia genitals.
>Of course, her sky-wagon couldn't be taken in fear of her purpose being made public, so the two of you had to make the trip alone.
>And the whole time you've been packing a tent (in your pants).
>It briefly occurred to you that you could relieve yourself with her mouth, but one: dem hors teef, and two: you wanna save up for the real thing.
 
>A few hours pass, the morning dew fades and the clouds have dissipated.
>As you reach the summit the sound of the waterfall grows louder, giving a nice backdrop to the otherwise rather silent afternoon.
>"We're here," she exclaims, running up and tossing aside her saddle bag.
>Her tail shoots up, revealing fucking nothing.
>SOON.
>You take your time following her, while you want to pork her pretty bad you're just fine missing out on the transformation.
>The sight of a brand-new vagina coming into existence might not be too attractive.
>You round the hill, and damn near roll off it again.
>There is Celestia, proudly facing you, mane flowing...
>With her massive horsecock kind of just handing there.
>"It worked Anon! I am now for sexual."
>Your brain doesn't agree, but apparently your dick does.
>Dong remains expand.
>You approach tentatively.
"W-why do you have...?"
>"THE MAGIC POOL HAS GRANTED ME MORE THAN I WISHED FOR," she thrusts happily a few more times, a bit of pre shooting out.
>Impressive, like a meaty cannon.
>"Now, take me, lover!"
>She spins around and kneels down in the pool, tail up.
>There are balls present.
>But...Fuck it man there is also a vagina.
>Wait a second, you think, body moving on its own toward her.
>There is a name for this.
>Some weird japshit...
>You pause, shirt half off and pants around your ankles.
>Futa, right, futa something.

>With a long line of clothes behind you, you approach Celestia completely nude.
>It's a little cold, but your chilliness disappears the second you join her in the pool.
>Steam rises up around you, breathing it in, you feel nice and calm.
>Alright, you're going to love the fuck out of this mare...futa and everyone is going to like it.
>Your dick draws near the entrance, twitching violently in anticipation.
>The heat of nethers is driving you mad.
>With the steam and her scent mixing, you're lulled into a partially-awake state of sextime.
>You slide in carefully, Celestia moaning as you two combine.
>She's already panting in pleasure.
>When you try to pull out she slides up along you length.
>The two of you get a rhythm of fucking going on, and you really get into it.
>You hardly notice how often her hefty package is tapping yours.
>In your current state you could care less, in fact it's kinda nice.
>Your brain suggests something mischievous.
>O-ok.
>Letting Celestia take control you lay back as she grinds against you, her walls convulsing with each movement.
>With your freed hands you grip her...cock.
>"O-oh~" is all she manages as you begin working on it.
>It's large, almost too large for your two hands.
>It's also warm and somewhat spongy.
>You give her a reach around, pumping as best you can.
>She's practically fighting your dick with her vagina, you wouldn't be surprised if there are some bruises at the end of this.
>Bending forward over her, you exclaim in joy as she neighs in pleasure.
>You're glad you're both bonding like this.
>It's nice.
>Oh and also her penis is becoming rather large, you think it might cum at any second.
>Hmm, you're pressing against her and something feels off, like there is something between the two of you.
>Probably your spin being shit at bending.
 
>You take one hand off her shaft, stroking with the other.
>She's neighing and clip-clopping in the pool, water splashing.
>With your-off hand you begin rubbing her breasts, which drives her up the wall.
>You are physically incapable of thrusting because of her ass-assault.
>Oh god them white, pleasurable mounds.
>They will be next, you think.
>After just a few seconds of your attack on her privates she rears up, cock shooting a thick load into the pool, cunt squeezing and squirting its soupy discharge.
>The display is more than enough to get your rocks off, and you cum inside with the force of a thousand futa sun-princesses, and continue to cum until there is nothing left.
>Tired as fuck the two of you collapse into the pool.
>It's not very deep, and you've got more than enough room to be comfortable.
>Breathing heavy and looking upward you hardly notice Celestia poking at your chest.
>"What are these, Anon?"
"Huh?"
>"Why is your hair so long? Why do you look so girlish? Is this normal for humans when they engage in coitus?"
 
 
"I-I don't know, it's this pool maybe," you try to stand up but Celestia is already on top of you.
>"I'm sorry, I can't help myself."
>Her package unboxes and centers itself between your new jiggly balls of goodness.
>Your lung-protectors are forced into position by her wings and she begins fucking the ever-loving milk(?) out of your chest.
"I-I don't consent to this," you manage, the head of her cock bumping your lips every word.
>"Ssssh, sssh," just let it happen.
>And you do so.
>With one of her hindlegs she presses against your dick.
>How her body is managing this is beyond you, mostly because you can't see, because you have a giant white horse fucking your chest.
>Celestia begins panting as she gets closer.
>Instinctively you open your mouth for her width.
>And that's the moment she gives in and cums.
 
>"I'm sorry I released my seed into your mouth, Anonymous," the princess says.
>You choke down her love, trying in vain not to taste it.
>G-goddamn it's exactly like...pound cake.
>Liquid pound cake.
>This can be done.
>Celestia tries to dismount, failing horribly, her dick shoves itself right at your nipple, forcing your breast to an odd angle.
>"Ah, very soft!" she says, taking a thrust.
"S-saw someone do this online," why is your voice so feminine, "please do not do this."
>"My apologies, love."
>You try to push yourself out from under her, damn near punching her in her cockhead.
>"Easy now!"
>She trots a couple paces away, and you remain half submerged, legs spread.
>Hey, looks like you've also gotten a bit of length.
>That doesn't really make up for the fact that you have D-cups and silky shoulder length hair now.
>"Anon! You seem to have also gained a vagina like mine."
>Eyes flaring in shock you shoot a hand down south, feeling around and yep.
>That's a vagina, right under your sack.
>Feels warm.
"Say...wanna try it out?"
>Celestia is taken aback.
>"I-I..."
>WHY WOULD YOU SAY THAT.
 
>Celestia's eyes flare with want, greed almost.
>She comes running.
>"Now you will be the princess!"
>Oh.
>Okay.
>She magics you into a strange position, your legs resting on her "shoulders".
>Her length presses against your entrance.
"Can we talk about this first?"
>"Royalty cannot second guess decisions!"
>She inserts her feature length into your interior crocodile.
>A shock of pain and the feeling of being...spread takes over you.
>"So this is what a mare feels like on the inside."
>You wiggle and worm, trying to get free of her.
>Although it its pleasurable, very much so, it's just too weird.
>She's bottoming out already, pulling back for a thrust.
>"Yes, continue to squirm!"
>WELL FUCK.
>Celestia goes at you like a rabid dog, making you feel very much like the bitch.
>Which is something you could get used to!
>Her thrusting becomes sporadic and tired, the splashing of the water more rushed.
>"I am close!"
>So are you.
>You return to your grinding state, hoping to finish off your partner in a fun way.
>And oh boy does she.
>Celestia fills your cavern with a water of semen, the feeling of driving you over the edge.
>Drunk on orgasms the two of you stop functioning and pass out.
>It would be unfortunate if a hiker were to show up here.
>Or someone searching for the missing Celestia.
>But you can think about that right now, you've got a load of horse semen in you and you're sleepy.
