Rainbow Dash, roughly a week ago, had confessed that she had been attracted to Fluttershy. However, Fluttershy had turned her down and things since then had been awkward between them.

So when she received the invitation from Fluttershy about spending the weekend, she instantly accepted, she wanted to do her best to not only repair their relationship but also spend time with the critter caretaker.

Fluttershy had invited Rainbow to a quiet place in the forest, near a creek with a short waterfall. “Hey Dashie,” Fluttershy asked, avoiding eye contact while her cheeks tinged with a pink hue. “Can you set our picnic? I’ll go check the water…” Rainbow agreed. She quickly laid out their picnic mat, basket, and weighed down the corners with some rocks, and turned around to see Fluttershy had taken her clothes off, bathing under the waterfall.

Rainbow then stripped herself, giving Fluttershy a surprise when she approached her, suddenly asking “Can I join?”

“Eep!” the shy mare squealed, glancing quickly at her athletic friend’s now wet body. “Umm, ok… can you wash me…” she asked softly.

“Mhm,” Rainbow replied, cupping some water in her hands, and sprinkling it over Fluttershy’s shoulders. She then, as gentle as a Wonderbolt-to-be could, massaged her hands over Fluttershy’s body fur. “Mmh…” Fluttershy quietly moaned, placing her hand over Rainbow’s. “Right there…” After a while, she turned around to face her friend.

“Close your eyes Dashie,” Fluttershy squeaked. “I wanna wash you this time...” Rainbow Dash, being all too familiar with Fluttershy’s soft voice, understood what she asked, and closed her eyes.

Rainbow felt Fluttershy’s body press onto hers, the timid pony’s softer stomach on the athletic mare’s toned one, as well as their chests pressed together. Rainbow could feel her friend’s more tender breasts rub against her firmer ones, despite being similar in size(with Fluttershy’s slightly larger), the feel was noticeably different, especially to a pegasus as in tune with her nature as Rainbow was. She also noticed Fluttershy rub her body against hers, feeling their breasts and nipples caress each other. Fluttershy, meanwhile, stifled her moans from the sensations she felt.

Rainbow was surprised at Fluttershy’s physical contact, as she knew this wasn’t something the shy mare would do just then and there, but she also wanted more contact like this, especially after things between them got awkward. What shocked her enough to pull free, was when Fluttershy started nibbling and licking her ear.

Fluttershy’s eyes widened at the speedster’s sudden retreat. Rainbow, whose eyes were also wide in shock, stammered, “Wha- What was-that’s a--?”

“I’m sorry…” Fluttershy said. “I turned you down because I thought we had something as close as what the Princesses have…” she then paused as she looked towards the general direction of Canterlot. “But then… we saw them making love… And that made me realize I was wrong… Since I turned you down, I felt awkward with you, and I could notice you were being hesitant…”

“I didn’t want to be pushy,” Rainbow Dash said. “And so I--”

“No, I understand, In fact, I kinda…” Fluttershy interrupted. “But I… Oh, for fluff’s sake, I can’t take it!”

Fluttershy then dove her face towards Rainbow Dash’s, capturing the daredevil’s lips into a kiss. Rainbow Dash, initially surprised at first, immediately returned the kiss.

Rainbow then wrapped her arms around Fluttershy, as Fluttershy slowly caressed Rainbow’s back, underneath her wings. The pegasi continued their kissing, as their wings slowly unfurled as they got more passionate. Fluttershy then felt something push against her marehood, taking her by surprise. She suddenly broke the kiss, and pulled away from Rainbow.

“Wh-wha-what was--” She gasped as her eyes caught on the culprit.

Rainbow looked at Fluttershy, confused. Following her line of sight, she looked downwards, only to be shocked at the sight. In the place of her vagina, there was a set of male parts.

“What the--” Rainbow shrieked. “Why do I have a dick?”

Fluttershy covered her mouth as she gasped. “Will that even fit?” she wondered.

“I… don’t know… ” Rainbow gasped. “This must be the Princesses’ doing…” she thought out loud, remembering the magical ray that blasted her, Twilight, and Applejack.

“We did see them… Having those…” Fluttershy said, her cheeks to flush hot pink upon recalling the scene.

Rainbow took Fluttershy’s hand, and they went out of the stream towards the forested region past the bank. She then lay down on her back. “How about this? So you can control how I go in…” she suggested, her cheeks also flushing pink.

Fluttershy got onto Rainbow Dash, mewling a bit as her vulva caressed Rainbow’s shaft. She then slowly guided the tip inside, sending a jolt of sensations through both of them.

“The… tip…” Fluttershy panted.

“Yeah…” Rainbow replied, also gasping for breath. She then took Fluttershy’s hands with her own, interlocking their fingers. “Slowly does it…”

“Mhm…” Fluttershy nodded, making eye contact with her friend. ‘Her friend… who she will be mating with… oh my,’ her thoughts went, as she moved her hips down, easing the rest of Rainbow’s length in.

The moment that the whole of Rainbow’s johnson was fully inserted into Fluttershy’s sheath, Fluttershy found herself falling onto Rainbow, finding their faces close up, snout to snout.

“Flutters…”

“Dashie…”

They closed their eyes and started kissing in a more intense and passionate manner than before. Their arms slowly wrapped around the other, as their bodies slowly started rubbing sensually, as well as started moving their hips, introducing friction in their sex.

Rainbow moaned as Fluttershy mewled, as they both steadily increased the intensity of their lovemaking, further sending jolts of sensation through their entireties.

Fluttershy moved her hips faster, as she wrapped her arms around Rainbow’s head, locking gazes with her friend. “We’re… Mating…” Fluttershy gasped.

“I’m… Yours…” Rainbow replied through gasps. The shy mare then closed in to the speedster’s ear.

“You… Have… To take me…” Fluttershy whispered.

This instantly flipped a switch in Rainbow. She then rolled both herself and Fluttershy over, putting Fluttershy at the bottom. She then closed in until their muzzles were a quarter of an inch apart, and said, “If you say so…”

The lifetime friends closed in for another kiss, as their wings unfurled to full extension. Rainbow sped up her thrusts, as Fluttershy wrapped her legs around Rainbow’s waist to limit her to a short distance, as she also moved her chest in order to add friction between their breasts.

Rainbow’s mind was racing past the sound barrier, how did the awkwardness from a week’s time result into the most passionate moment she could ever had with her lifetime best friend, or is it now lover? Despite the questions, she also wanted this ever since she confessed, that she would be with Fluttershy like this. Fluttershy’s however, was rolling in unbridled emotions. Part of her worrisome side of the mind was fretting over the consequences on their friendship, while part of her passionate side was aching to be rid of the awkwardness, even if it meant such wanton mating with her lifetime best friend. She then gave herself to the moment, as Rainbow did.

They mated faster, harder, and more passionate. Closer and closer did they skirt towards the moment to come. They both broke their kiss, gasping for air, only for them to hit the ceiling of sensation.

“Flutters—!”

“Dashie—!”

“AAAAHHHHGGGHHH!”

Rainbow let it rip, sending a torrent of seed into Fluttershy’s womb. Fluttershy felt herself fill up with Rainbow’s cum, triggering her nethers to spray shecum violently.

The pegasi then both fell onto the ground, heaving and panting as they looked into each other’s eyes. Rainbow Dash then plucked a primary feather from her right wing, and tried to braid it into Fluttershy’s mane, behind her right ear. Fluttershy, turning pink from the move that the speedster did, and followed suit, primary feather from her right wing braided in Rainbow’s mane, behind her right ear.

“You’re making up for lost time, hmm?” Fluttershy cooed, touching noses with Rainbow Dash.

Rainbow then planted a light kiss on Fluttershy’s lips, letting out a chuckle. “I’m not wasting the moment…”

“You’re awfully fast, Missus Shy…” Fluttershy teased with a giggle.

“Somepony like you has gotta be Missus Dash on my watch…” Rainbow responded, nuzzling her snout with the canary mare.

Author's Note

Aaaaaand boom, one piping hot order of The Usual, coming up!

Finally, a FlutterDash story that isn't a oneshot (meaning I wouldn't have to chuck it into the Funsies compilation... also I'm plugging the Funsies anthology...)

Also, I had the idea of a pegasus-specific proposal practice(Again with the alliterations what is wrong with me) where a lock of mane hair behind the right ear of the pony proposed, is braided with a primary feather from the right wing of the pony proposing. Nifty but now I have to think how unicorns and earth ponies do, and how does it work in a biracial setting(insert how would it translate to pegasus-unicorn or pegasus-earthpony or unicorn-earthpony couples, ain't it fun when adding personal flair to worldbuilding leads oneself to digging a ditch one ends up falling in?)

Once again, enjoy and I hope you like it!
