Rainbow Rocks her World

Rainbow touched down in front of Rarity’s boutique, knocking, but walking in anyway. A voice called from upstairs.

“So sorry, darling, but the boutique is closed for a week, I have things to, ahem, tend to.”

“Oh I bet you do-you and half of Ponyville, Rares.”

Rarity came down the stairs, using magic to pat the sweat off her brow. “Oh, Rainbow Dash! I am very sorry, but I get…far too excited during my heat.”

“Well, I can help you with that-I’ve already helped ALL of our friends,” she said, sitting on a stool with her legs open, showing her peeking cock from the sheath.

“You know, I HAVE always wondered something-apologies for the crass inquisition-why, exactly, do you not use a spell to tuck it away? Isn’t it...not very aerodynamic?”

“A bit, but that’s why I usually have a potion, or Twi cast a spell.”

“Why not ask me?”

“You? Why would you know spells to HIDE dicks-you love cock!”

“I do...” she sat on a stool next to Rainbow, casting a spell. A sheath appeared between Rarity’s lithe legs, just as high class and sleek as the rest of her. “But not everyone else does. So, all of our friends?”

“Yup, all pregnant now, and I’ve got Twi’s in me,”

“My goodness, pregnancy is VERY chic right now-you should see how my maternal line sells...but...it would sell better if I was pregnant too...and I suppose any foal of yours would be wonderfully healthy.”

Rainbow grinned, “Damn right...so, you want me to mount you,” she winked.

“Goodness, so crass...save the dirty talk for the dirty deed,” she purred, getting up and flicking her tail playfully to show her fertile slit and heavy balls. “But you know me, I must get dressed up for special occasions,”

Rainbow rolled her eyes playfully, using her hooves to slowly stroke her cock, imagining being balls deep in such a high class slut-she’d never asked, but rumour had it Rarity had once slept with Celestia to get a good room at the castle. She wouldn’t be surprised if, as apocalyptic a slut as Cadence was, Rarity had bagged that princess as well.

Oh mane, she had to ask Twi if she’d ever fucked her own brother. Her strokes got more frantic, that was just too fucking hot. She slowed as Rarity cat walked back in, showing off her lingerie.

A corset saddle, socks to her shoulders and a garter and stockings, all the same shade as her mane. Rainbow knew shit about fashion, but even she could appreciate the contrast of royal purple on unmarred white.

“Oh by Luna’s chilly moonpie...a...a saddle?” Rainbow squeaked, taken off guard.

“Well, I HAVE always wanted to try it, and I...know I can trust you,” the blush showing easily through the white.

Rainbow got up, walking over and running a hoof, carefully, over Rarity’s form and outfit. “Wow...even I can tell this is some good shit...you sell this too?”

“Uh, well, by order,” she giggled into a socked hoof.

“Oh hoh? Do ya mean you take orders, or did ya get a royal order?” she asked, wiggling her brows.

“Well, let us just say, I know all the princesses measurements for many reasons.” they laughed together, before Rainbow shamelessly groped Rarity’s prim and proper slit with a hoof. The fashion pony jumped a little, before giving Rainbow a sexy leer.

“My my, getting ready to ride, my Wonderbolt? I hope you last longer than ten seconds flat,”

“Oh trust me Rares, in THAT outfit, I’ll only BE flat for ten seconds!”

She mounted up, Rarity bracing her legs, Rainbow careful not to put too much weight down. Rainbow teased them both, sliding her slick cock along Rarity’s slit, to balls, along that thick sheath and rubbing their cocks together. “Mmmmh, fuck Rarity, this is...so kinky,”

“Fuck Rarity is where I hope this goes, yes...and this is kinky to you? You should see Celestia around cake,” she giggled.

“I hope to,” she admitted. “You’re the last of our inner circle, and I...kinda wanna do all the princesses-get the full set, ya know?”

“I do,” she replied, rolling her hips against the pegasus, “Quite some impressive notches on your bedpost, I’d say. And I support- neigh, encourage it. You would make pregnancy even more fashionable, darling, and since you are the father...perhaps you would get more offers,” she winked.

Rainbow’s grinding got more enthusiastic. “Oh hell yeah...spread my oats all over the place! But, ya know...even if I didn’t, I’d uh...still be happy that I got this with all of you. It feels so special, even more than usual.”

Rarity smiled, “Oh my, going soft?”

“Not where it counts!” she announced, sliding into Rarity’s dripping cock catcher. Rarity was ready, rolling her tunnel along the cock. Rainbow nuzzled her mane, “Ooooh, Rarity...your cunt is so talented...”

“Mmmph...I do have practise, darling...I enjoy speeding up my business deals, you could say,”

Rainbow moved her hips, slowly, enjoying the clench and mating. “Gotta take my time...spent the morning with Big Mac and AJ, wore me out,”

“Oh I bet, darling,” she smiled, “Take all the time you need, that wonderful cock filling me up is more than enough for now...”

They moved together, slowly, sensually, enjoying the slow pace. For a bit, at least, until Rainbow’s front legs gripped around Rarity’s middle, humping away happily.

“Oh, darling! Yes, just like that!” she cooed, Rainbow doing her best to do as asked. She nibbled at Rarity’s fur, almost a wingless version of preening. Rarity soon saw why pegasus ponies did this-it made her tunnel tingle wonderfully as they mated. Rainbow saw how much she liked it, and kept doing it, keeping her thrust speed up, and making sure she hilted with every crotch pocket stuffing.

Rarity moaned, “Oh darling...I am going to cum! Push through my womb, hold me down and breed me like a Canterlot whorse!”

Rainbow smirked, pushing Rarity’s head to the ground, her rump still in the air, and began battering down the well fucked cervix. It took moments, and soon she was stretching the womb’s walls.

“You like being treated like dirt, huh? Yeah, you’re just a cum sock to get me off and have my kids!”

Rarity got off hard at her friends debasing, girl cum splashing on Rainbow’s busy hips, Rarity’s own cock squirting hot love all over her carpet. Rainbow yanked her mane, taking a mouthful of purple curls and pulling as her cock throbbed, sending wave after wave of hot, fertile seed into Rarity’s milking tunnel and greedy womb.

Rarity’s legs gave out, and both of them collapsed into a heap, panting as they got their breath back. Rarity rolled to hug her, both enjoying the snuggle.

“You...you know I didn’t mean the nasty things, right?”

“Of course darling,” she assured Rainbow. “I just enjoy a bit of dirty talk, dirty talk is rarely the same as a pony’s actual feelings,”

Rainbow nodded, relieved, and nuzzled her. Finally, she stumbled to her feet. “Ya know what...I think I’m gonna ask Gilda to visit...Twi gave me a book on interspecies mating that I actually read for once, and I’m pretty sure a pegasus can knock up a griffon,”

Rarity got up a bit more dignified, slowly taking off her clothes, sore in a good way. “Well, I wish you all the luck, darling!”

She waved briefly as Rainbow left, flying again to rest her overtaxed limbs, back home to her mare friend.
