>You can't surpress your giggles as you walk through Ponyville's streets
>And neither can your female counterpart
>You're Bubble Berry, and you're about to pull a whole new kind of prank
>Luckily, the town itself isn't any different, only the inhabitants
>After you and Pinkie had banged, she quickly got you up-to-date on where you were
>Essentially, everypony you know is here, but swapped in gender
>And all of them seemed to be friends with Pinkie as well!
>They all greeted her happily
>Well, as happiily as they could with a stallion clone hopping next to her
>Which as still pretty happy
>"So, one last time Berry."
>Her cheery voice pulls your out of your thoughts
"Yes, so I'll go up to Rainbow Bl- er, Dash, and I'll be like 'ohmygosh Rainbow Dash Dusk Shine did a spell and now I'm a guy!"
>Pinkie claps her hooves together
>"Almost! It's Twilight Sparkle. Sort of like Dusk Shine, but synonyms."
"Twilight Sparkle, yes."
>"So now all there's left to do is find Rainbow Dash an-"
>She interrupts herself by shoving you into the nearest bush
>Luckily, you fit in quite snugly
>The reason why she did that shows itself soon enough
>Mare Elusive
>You and Pinkie had both agreed you shouldn't meet any of her friends before pranking Rainbow
>"Hello Pinkie Pie, a lovely afternoon isn't it?"
>Yep, that's Mare Elusive
>"Hi Rarity! Sure is! Nothing strange going on!"
>Good job Pinkie, act natural!
>"Say, Pinkie... Was it me, or were you hiding something in the bushes just now?"
>"Oh? Was I? J-just a mannequin in case of a mannequin emergency! Yeah!"
>"So that's where they went!"
>"What, no, your mannequins are staying at the Clubhouse! Sweetie Belle wanted them for a few cutie marks, so I helped move them!"
>Funny, you remember helping Silver Bell out yesterday.
>Rarrity seems shocked
>"That brat! I'll show her!"
>And with that, she runs off
>You carefully step out of the bush, and shake some twigs out of your mane
"Alright, so as I was saying, let's find that cloud!"
>Pinkie giggles
>"Silly, I was saying that!"
 
>You find out where Rainbow's napping soon enough
>It isn't often you find a snoring cloud above Ponyville's park
>You and Pinkie silently approach it
>You look at eachother, and nod
>Pinkie quickly takes cover in the background, expertly hiding herself from view
>Alright, ready for Operation Magic Accident
>You take a deep breath, and...
>"RAINBOW! Rainbow, wake up!"
>The cloud mumbles
>"Rainbow Bl- Rainbow Dash! Something terriffible happened!"
>Finally, a reaction
>You see Rainbow's head peep out from over the edge of her cloud
>She looks almost exactly like Rainbow Blitz, but a mare of course
>"So is it terrible or terriffic? Seriously, why'd you wake..."
>Only now does she notice you're a stallion
>"Pinkie? Something's off..."
"Well, yeah! I was visiting Dus- er, Twilight, and she did a magic spell on me, but it went wrong, and now I'm a stallion!"
>Rainbow jumps off her cloud, and slowly glides down to you
>"So that's pretty bad, right?"
"Yes! No! It's both! It's terriffible!"
>Rainbow tilts her head
>"How is this..."
>She looks you up and down once more
>"... a good thing?"
"Well, you see..."
>...
>Crap
>You haven't thought it through this far
"Um... Just gimme a sec, okay? I thought I heard the bushes rustling."
>You leave Rainnbow Dash in confusion as you zip over to the nearest schrubbery
"What now?"
>Pinkie's voice soon answers
>"Um... Oh! OH! Stallions have stallion thingies, right? Tease her with it!"
"Alrighty! But... She's our, er, your best friend..."
>"So? I'd do her if I was a dude! Wouldn't you?"
"Oh! Yes, of course! How could I forget! Remember me to take you to my place one time."
>And with that, you bid the bushes farewell and bounce back to Rainbow
>"So have the bushes told you what's good about a whole new body yet?"
>She seems a little irritated
"Of course they have! Of course it's all strange and new, but it's also all strange and new, and there's a huge plus!"
>"What? Mare attention?"
"Of course not, silly!"
>You stand up on your hind legs, showing off your (not) new appendage
>Within half a second, Rainbow's pink eyes find their target and lock on it, and her face starts to light up
>Success
"You won't believe how different it feels!"
>Rainbow's answer is nearly a whisper
>"How different..?"
"Well, um..."
>You don't actually know what being a mare feels like
>"Like, really really different."
>Good thinking!
>Dash doesn't even seem to hear the answer
>She swallows audibly, her gaze still fixated on your crotch
>Her expressions holds up somwhere between amazement, embarrassment, and curiousity
>"Twilight... Gave you this..?
>You nod wildly
"It does its job too!"
>A tiny droplet of drool escapes Dash's mouth
>She quickly shakes her head to came back to her senses
>"Really now?"
>She's trying desperately to act cool
>She really is just like Blitz
>You giggle
>You're so gonna take advantage of this
"Wanna see for yourself?"
>Dash's face lights up red with a deep blush
>Success!
>Now for part two!
>You quickly grab her hoof, using the opportunity to drag her into the nearest alley
>Don't forget to wink at the bushes on your way there!
>To your surprise, Dash start leading the way halfway there
>That eagerness, and not to mention that plot...
>It's magic to your stallion bits
>By the time you've reached your destination behind the cinema, you're already at full mast
>Dash turns to face you
>She looks a little nervous
>"So..."
>You giggle once more, and stand up on your hind legs again, this time to show her your full pride
>Rainbow Dash flinches
>"O-okay! Okay! It works! Good to know!"
>She would've spread her wings for departure if they weren't already unfolded
"Hey! Dashie! You can't just leave poor me like this! What happened to loyalty?"
>Dash flinches
>For the next few seconds, she doesn't move
>You can almost see the Celestia and Discord on her shoulders
>Eventually, she raises her tail just far enough to shows her fun place
>She doesn't even turn to look at you
>"Alright then... A quickie. Just one!"
>You can practically hear her blushing
>This is it!
>You walk up to her and place your hooves on her flanks
>Damn, Rainbow Blitz had a nice rear, but this is even better!
>You get into position, ready to get this party started
"Ready?"
>"Not y-"
>You push your hips forwars, unable to hold back a moan as you finally enter that sweet pussy
>"Fuck! Pinkie! I said not yet!"
"Oopsie, it slipped in!"
>You start moving your hips back and forth, thrusting in and out of Rainbow at a rapidly increasing pace
>"It didn't 'slip in'! Not so fast! S-stop! It's huge, it's gonna break something back there!"
>But you keep going, faster and faster, harder and harder
>Dash's protests gradually turn into pleasured moans
>"Okay, you know what, keep going like that!"
>She starts thrusting her hips back at you, timing her movements with yours
>Her hind legs start shaking
>"Fuuuuuck, speed it up! More!"
>You happily oblige, and she happily takes all the extra energy
>You bend over the mare under you, wrap one leg around her, and start poking her clit with your hoof
>Her legs start shaking even more
>You can't help but smile as Rainbow Dash experiences whole new levels of pleasure from your hoof and dick
>She brings a hoof up to her face and bites it hard
>It quickly becomes apparent she's holding back moans, or screams even
>You never before wondered if Blitz is a screamer, actually
>Dash's insides start contracting around your dick, tightening and pulling around it
>"Fuck, that's so good! Slow down a bit."
>You shake your head, and keep going relentlessly
"You wanted a quickie, so I'm not gonna waste any time!"
>And not wasting any time is exactly what you're doing
>You feel pressure building already
>You don't even fight it, you just let out a 'woo!' as you pour out inside Rainbow
>"Woo? What's happening?"
>You don't stop for even a split second
>"Pinkie, did you cum inside me? Pull out!"
>Saying that you keep plowing Dash with renewed vigor'd imply you lost some to begin with
>"I said one! Just one!"
>You giggle, for as much as giggling's possible after having just came
>Surprisingly possible
"Sorry, couldn't help myself, but the second one is never long!"
>Except it is, of course
>For five long minutes, Dash is squirming, wriggling and moaning under you
>All the while, you keep pumping back and forth at an unforgiving pace
>Finally, finally sweet release comes
>You do pull out this time, so you can coat Dash's back in a nice pack of pearl necklaces
>Why she'd wear them on her back, you'll never know
>You step back again, breathing pretty heavily
>"Damn Pinkie, I said only one!"
>You smile sheepishly
"I said sorry, it just felt so good!"
>"It's alright... I'd hate to say it, but you're good pretty at this yourself. When do you change back?"
"Change back?"
>You giggle
>It's time for the last part of the plan!
"Never."
>"What?"
>Rainbow turns to face you, and grabs your shoulders
>"You mean you're stuck like this forever?"
"Well, duh. But it's okay, I've always been like this!"
>"Huh? But... I'm pretty sure you were a mare earlier today."
>"That's because I was! I still am!"
>Pinkie hops towards the two of you, giggling with you
"I'm not Pinkie!"
>Rainbow Dash is confused!
>"But... You are Pinkie... Or just like her... Down to the cutie mark..."
>Pinkie takes place next to you, and wraps a hoof around you
>"This is Bubble Berry, he's me from another world!"
>"You from another... what?"
"Not another what, another world! Geez, Pinkie just said it!"
>You and Pinkie break into a laughing fit
>By the time you're done, Dash is still trying to process the information you've just shared with her
>You decide to leave her alone with her confusion and leave the alley
 
>"You seriously did her?"
"Well, yeah."
>You and Pinkie are walking through one of Ponyvilles many streets, talking over how the prank went
>"I only said tease, silly. Not that I mind of course, though I am a bit jealous."
>You both giggle
"Hey, I'd do Rainbow Blitz if he was a mare, and here she is!"
>"That's true, that's true."
"So? Where to next?"
>Pinkie thinks for a second
>"We could bake the huuuugest cake at the Corner?"
"Ooh! Or we could throw ourselves a clone party!"
>"Only ourselves? That'd make nopony smile."
>Somewhere above Pinkie, a bulb lights up
>She stops in her tracks, and claps her hooves together once
>"Of course! Making ponies smile!"
"We're gonna throw a Super Duper Double Party Pony Extreme Extravaganza?"
>"Later! But while you were, um, doing Rainbow Dash, I had another chat with Rarity!"
"And? And? What's she designed this time?"
>"Nothing! She told me she's been having bad luck with the stallions lately though, so maybe you and I can bring a smile to her face?"
>You extend a hoof, which is bumped by Pinkie shortely thereafter
"Of course! But let's do dinner and sleep first."
>"Well, duh! You can't make ponies happy ponies when they're sleeping! And it's even harder if we're sleeping ourselves!"
>You smile, and the two of you start making your way to Sugarcube Corner
>You're already liking this place
