You're Anon, a human, in Equestria, the land of small, colorful ponies. You've been here for a while, but most of the ponies are still afraid of you.
There are some notable exceptions - namely the Elements of Harmony, six very important ponies who have saved Equestria many times, through the power of friendship. They'd all been intrigued by your appearance, especially Twilight Sparkle.
Although Twilight has been keen on studying and documenting your species, you'd rather spend time with Rainbow Dash, the awesome tomboy.
One day, when you are telling Twilight about human sociology, Rainbow interrupts. She requests that you come visit her cloudominium above Ponyville.
Twilight agrees to let you use her hot air balloon to get there, and she enchants you with a cloudwalking spell. You depart from her castle and take the balloon up to the house-on-a-cloud. Once there, you probe the cloud with a foot. The cloudwalking spell seems to have succeeded.
"I sure hope this spell doesn't fail on me", you think to yourself.
Dash lets you in, and directs you to her bedroom of all places. Her room is quite similar to a diehard brony's room, with posters of herself all over the place.
"So...what do you need?", you ask, in as nice a voice as you can muster, in hope of counteracting the overall rudeness of the sentence.
"I was just thinking...maybe we could spend some time together...since that egghead Twilight is always studying you and we never get any quality time with each other."
"Good idea. Twilight's interest in my species is fine and all, but explaining to her how we've managed to get by without flight or magic gets boring after a while."
She sits down on her bed, and beckons for you to join her. You do so, taking up a criss-cross-applesauce seating position.
"This bed is awesome...just like you!", you remark.
"You don't need to remind me", she retorts. You smile at her reply.
She re-orients herself to be sitting directly next to you. You understand what she wants, and decide to make the first move. You look at her, admiring that sleek, athletic body, the distinctive rainbow mane and tail, and those lovely magenta eyes.
Your fingers idly comb her surprisingly soft mane.
"So...maybe Twilight isn't the only one you should teach about your species...", she says, staring at you with bedroom eyes.
You stop caressing. "I'm afraid that you might not be satisfied with what I have to offer."
"What do you mean?"
You sigh. "To put it bluntly...I'm afraid that the stallions of your world have a bigger dick than I do."
She laughs it off, not understanding that it might be true.
"I'm serious."
"Really?"
"Yeah."
She sighs. "Well, I'm a virgin, so it wouldn't matter as much. Besides, none of the stallions really have a crush on me."
You're surprised at all this news. "What about Soarin?", you ask her.
"He's kind of a jerk. So are most of the other stallions. Anyway, can we get started?"
"Sure."
She turns around and presents her plot to you.
"Do you want to be done like a human or pony?", you ask her.
"Human is fine."
"You sure?"
"Yeah."
"For starters, you'll have to lie on your back. And be advised that we humans generally don't start right away. We like foreplay."
She obediently lies down, flips over, and spreads her hind legs. Her clitoris winks upon that last action, but you don't notice. You lie down on your side and rub her belly, expecting her to dislike it. Surprisingly, she seems to enjoy it.
You slowly work your fingers lower and lower, to the main prize. Upon arrival at her vagina, you circle your fingers around the labia.
"Now I'll need you to not resist my actions.", you request of her.
With that said, you part her lips with some difficulty, and insert your middle finger. She moans a bit, the most feminine sound you've ever heard her emit.
"You like this?", you ask her, smiling, while pistoning with your finger.
"Ahhhhhh...yeah...but is this really how humans do it?"
"We're only getting started. This is the foreplay."
"Does it get better?"
"Oh yes."
"When?"
"When the time is right."
You pick up the pace of your pistoning. Dashie lets out another moan, neglecting to close her mouth after the sound has emanated. Her hot, slimy insides are wringing at your finger. Nonetheless, you continue what you're doing.
After about a minute of the more rapid fingerbanging, she lets out a longer, intense moan.
Sensing that the time is right, you decide to move to the next phase. You pull out your finger and start taking off your clothes. Rainbow watches, fascinated, as you remove your underwear and an erection springs out in its wake. It's mediocre by human standards, but she's either being polite or else it actually does size up with the stallions.
"And you were worried about THAT being too small?", she scoffs.
"When you do it with a stallion, you'll look back and laugh at me. Guaranteed."
"I don't know...that's pretty big." She admires it more.
"So now comes the good part."
You lie down to her side, and move her body so her slit is aligned with your tip. Then, you grab her plot and force her over you. Doing it sideways was an interesting choice, but you're still able to thrust.
Her walls clamp around you tightly as you work on her. She is quite satisfied with your performance so far. Either that or she's appeasing you once again, which is out of character for her, but you deem it plausible.
Surprisingly, you haven't orgasmed yet.
Her hind legs begin to flail, brushing against you.
"A-Anonnnnnnnnnnnnnnnnn! I think I'm gonna--"
You realize what's happening and pull out as quickly as possible, then hold her down. The writhing continues as orgasmic fluids squirt from her nethers. You want to sample the stuff, but you continue to restrain Dash as her spasms continue.
After you're sure that she's done with the flailing, you feel the cum rushing to escape. On an implulse, you shove your dick into her mouth and let loose. Rainbow emits muffled sounds upon this action, but you don't stop.
You pull out. She swallows it all. Then, you go back to her vagina and lick off her fluids. They're delicious and you crave more, but you must hold back.
"So...did you enjoy yourself?", you ask her.
"Yeah!!!!! Can we do it again sometime?"
"Maybe..."
You put your clothes back on.
"Well, I should probably get going now. I'll see you later."
You start out the door, but turn around mid-way.
"And don't speak of what we just did to ANYPONY."
"I won't."
You finish leaving her room, and you're about to leave her cloudominium.
"Anon..."
"Hm?"
"One last thing before you leave."
"Yes, Rainbow?"
"Um...can you pick me up?"
You oblige, bringing her face to the level of yours.
She puts her forelegs on either side of your head and presses her mouth against yours. Your tongues meet for several seconds, then you simultaneously back up.
"Thank you, Anon. That was awesome!"
"And thank you too, Dashie, for letting me do all that."
"I love you."
"Love you too."
And with that, you exit her home and descend back to Ponyville in the hot air balloon. When you arrive back at Ponyville, Twilight is eager to hear what you did.
"It's kind of hard to describe...but let's just say I'd do it again anytime."
Time: Three days after the events of Part 1.
You're back at Twilight's castle, where you continue to share the pitfalls of your world with her. She frantically scribbles down notes, enamored with the subject at hoof. Then, in a similar vein to Part 1, Rainbow Dash interrupts you.
"Hey Anon, Spitfire wants to talk to you!"
"What the hell could Spitfire want with me? We barely even know each other!", you think to yourself.
"I'll need to borrow that hot air balloon again, Twilight."
Twilight sighs. "Can it wait?"
"Do you want to keep learning about my world?"
"Yes, of course."
"Then I'll be borrowing it now. And I need the cloudwalking spell, please."
She reluctantly enchants you with the spell.
You walk out of Twilight's castle to the hot air balloon parked out back.
"Now Rainbow, you'll need to fly slowly, because I have no clue where I am to go."
"The balloon will take you up to Cloudsdale, and I'll show you from there."
You take off, up into the sky, before entering the floating city. The Pegasuseses are afraid, as most other ponies are, so they stay out of your way while exchanging nervous whispers and glances. Dash thankfully is patient with your comparatively-lethargic pace.
You arrive at the destination, which is not Spitfire's house, but instead the Wonderbolts' barracks. You knock on the door, and Spitfire answers. RD heads off to somewhere else on the complex.
"You requested my presence?", you ask nervously, slightly fearing the harsh yellow Pegasus, who is inexplicably in her Wonderbolt uniform.
"Yes. Enter."
You enter the room and close the door behind you.
"So, Crash says you're pretty good?"
"Pretty good...at what?"
"Did you eat a bowl of amnesia for breakfast? Remember what you two did the other day?"
"Wait...she told you?!"
"Yeah."
"..."
"So let's get to it, Mr. Anon."
"Uh...you see...I'm not sure how Rainbow Dash would feel about this..."
"It's either this or Crash gets kicked off the Wonderbolts."
"..."
What a tough decision! But alas, you know how much dear Rainbow loved being a Wonderbolt. You reluctantly agree to give her what she wants.
"Excellent." She opens another door in her office, which leads to what appears to be a bedroom.
"You live here?"
"Yeah. Gotta be ready bright and early for practice."
She sits on the bed, looking at you with bedroom eyes. You join her on the bed, once again thinking of how Dash will handle the news of this later.
Spitfire realizes that she is still wearing the Wonderbolt flying suit. "Can you help me out of this thing?"
"Sure." She lies down on her back. You locate the long metal zipper, normally concealed by a flap of fabric. You bring it down slowly, but not too slow so as not to take too much time. Once that is done, you are able to free her head and legs from the suit quite easily. You wonder if she genuinely needs a second set of hooves to get suited up, or if she just wants you to be seduced by the prospect of stripping her. Probably the latter.
She flips over and lifts her rear into the air, expecting you to do her like a pony.
"That's not how we humans do it."
"Is it the way you did Crash?"
"Nope."
"Then do me like a human."
You flip her back over and spread her hindlegs.
"We humans start with foreplay."
"Doesn't matter, just get to it already."
You give Spitfire a similar but more haphazard fellatio, caressing her belly, and working your way down towards her pelvic region.
"This is...different...", she remarks.
"Remember that we're only getting started. It gets more similar to the way ponies do it soon enough."
Your fingers have reached the destination. You encircle her labia a few times. Her clitoris winks at your touch.
Instead of fingering, like what you did with RD, you decide to try something different. You lie down, and begin to lick around her opening. She grins lustfully. You lick some more, before seeing if you can't slip your tongue in. Surprise, surprise, your tongue is not enough to part her lips. Oh well, it was worth a shot. Then you decide it's time for the good stuff, so you stop licking and start taking off your clothes.
"Now don't laugh.", you command as you take off your clothes. You know that she'll laugh anyway, because she's almost certainly seen stallion dick.
You finish stripping. Surprisingly, she does not laugh at your small (by human standards) package, instead still giving you the bedroom-eyed stare. Maybe I do compare with the stallions, you think.
Hesitating for a brief moment again, you contemplate what you're about to do. You recall what Spitfire threatened, which puts your mind at ease that by doing this you'll be keeping Rainbow on the Wonderbolts.
You lie down next to her, and turn her to face you. You align yourself with her opening again, then force yourself in by pushing her flank towards you. She moans a bit as you insert and begin to pound her. The walls clamp down on your dick, but for some reason not as tightly as Rainbow's did. It's not because RD was a virgin, as you believe these equines are likely similar to those of your own world in that they can essentially adjust their vaginas to accomodate any size dick.
You keep going, building up speed and force as you go. She moans again, this time more intensely. You feel that you're about to let go, so you withdraw and bring your dick to her mouth.
"What the--", she begins, but is cut off by your sudden plunge into her mouth.
You force her mouth over you further, and then finally, you feel that telltale sign that the cum has been released. You pull out and instruct her to swallow it. She obliges.
"So...what did you think?", you idly ask her as you put your clothes back on.
"If you were a Pegasus, I think I'd let you into the Wonderbolts from that performance alone."
You don't believe her statement, because she didn't even orgasm. You show yourself to the door as she settles in for a nap, of all things. Outside her office, Rainbow is waiting for you.
"Rainbow, I need to have a talk with you", you say, as you pick her up and carry her out the building, following the directions she gives you.
"I'm very disappointed in you for letting Spitfire know what we did the other night."
Her ears flip downwards and she holds back tears. "I'm so sorry, Anon."
"I still love you, but just be aware that your actions might have caused some unintended consequences."
"Like what?"
"Spitfire demanded that I have sex with her, or else she would kick you off the Wonderbolts."
Silent tears trickle from her eyes. "So, what did you do?"
"I did her, because I know how much you love being a Wonderbolt. I hope you can find it in your heart to forgive me for cheating on you."
"I forgive you, Anon. You made the right choice to do that."
You arrive back where you parked the hot air balloon. You set Rainbow back down on the cloud-ground, and get ready to descend back to Ponyville. Before you start undoing the ropes that secure the balloon into place, Rainbow takes your head again and kisses you. Your tongues don't connect this time, but it doesn't matter. At the end of the day, what's important is that you saved your dear Dashie from getting kicked off the Wonderbolts, and had sex along the way, even if it wasn't with who you wanted.
Back on solid ground, Twilight teases you. "So I guess you're the first human Wonderbolt or something?"
"No. I will not disclose what I did, because I'm not proud of the decisions I had to make."
She procably knows what you're meaning, but you don't really care.
