As soon as you left Rainbow's house, you could already feel your flight beginning to feel more natural. As you moved your wings up and down, it had begun to feel like your ability to fly had always been there, hidden below you human instincts.

"Hey, Rainbow!" you called, "Did Zecora tell you what that stuff was?"

That was probably a question you should have asked before using it, but it seemed to be doing you good so far. As shameful as it was, you wanted to make more of it yourself. With flight now feeling this natural, it would be almost impossible to return to how it felt prior.

"Eh, not really," Rainbow replied, much to your disappointment, "All she said was 'Use this substance as I say, and it will keep your instincts at bay,'"

Neither you nor Rainbow knew what that meant, but it was quite a task to understand Zecora's riddle-like statements.

"So, anyway, Double Rainboom time?" you asked, eager to take down the beast of a task that had defeated your previously.

"Not yet. How about something to warm up first?" Rainbow suggested, not wanting you to get yourself hurt. As much as you wanted to try the Double Rainboom now, a warm up was probably for the best.

It was funny. Not so long ago, Rainbow Dash was the one who could barely wait to do a Double Rainboom. Now the roles had completely swapped.

"Ok, sure! What've you got in mind?" you asked, hovering patiently besides her.

Rainbow looked around for a second, searching for a task that could serve as a suitable warm up to a Sonic Surge. Quite quickly, she came up with an idea.

"5 laps around my incredibly awesome house!" she suggested, swirling one of her hooves around in a circular motion as indicating the route.

"Is that all?" you asked, trying your best not to sound cocky.

"What, don't think you can take it?" Rainbow mocked, in an attempt to tease you.

"I don't think I can take the boredom." you said, looking at the incredibly small lap or a circuit that was Rainbow Dash's house.
In terms of housing, Rainbow had an incredibly large house to be living in in her own. In terms of a flying route, not so much. At the average Pegasi's flight speed, it would probably take two or three seconds to complete a lap around her house.

"10 laps!" Rainbow suggested.

"Boring." you said, tracing the lap route with your vision. It was particularly boring, like you were saying. It was more so that it didn't serve as a good warm up to a Double Rainboom.

"15 laps!" she suggested, giving you a sly smirk as if testing your limits.

You gave her a sigh of boredom, as well as your own smirk, as if wanting her to push you further. She seemed to get the message.

"Daring today aren't we?" Rainbow mocked, "25 laps around my house in under a minute with your eyes closed!"

Well that went from a zero to a hundred incredibly quickly.

"I'm not doing that last part." you laughed, preparing to take off into a high speed flight.

Usually taking off at a high speed required quite a bit of effort from you, but this time it felt almost effortless; natural. Even preparing yourself for the takeoff felt weightless.

"Remember, one minute, Storm!" Rainbow added, in an attempt to to add some pressure to you. She was clearly having a lot of fun seeing how far your 'new' wings could take you.

You weren't really fazed by the added pressure. In an instant, you shot off in a burst of speed that was nearly double your usual speed. It was strange how your familiarity with your wings effected your flying.

In under five seconds, you had already circled the house once. Only 24 more times to go.

Rainbow Dash watched you, intrigued as too how you would overcome this challenge. This was something that even she would find difficult.

Within 15 seconds, you had completed four laps around the house. This wasn't gonna work.

At this rate, you were gonna get nowhere near the 25 laps you needed to complete. You were gonna need to pick up the pace.

"Maximum overdrive!" you said to yourself, attempting to push your wings as far as they could go. Surprisingly, it didn't hurt you, but instead it just felt like a regular excersise.

It felt as if the air was splitting around you, but not to the point where it would form a vapour cone. You wanted to go fast, but not fast too the point where you would cause a Sonic Surge.
This was only a warm up, after all.

After increasing your speed, you had completed 16 sixteen laps within 30 seconds. If you kept this pace up, you were gonna do it easily.

There's no way he's gonna do it. Even I probably couldn't do that, Rainbow thought as she watched you spiral around the cloud house repetitively.

How wrong she was.

By the time that 50 seconds rolled around, you were already finishing up your last lap. Proud, yet also somewhat exhausted, you halted to a stop.

"How... Was... That..." you panted, instinctively folding in both of your wings.

Rainbow Dash stared at you in disbelief, barely able to process what you had just done. Going that fast without causing accidental causing a rainboom was impossible, yet you just did it.

"Pfft! I could've done it way faster than that!" Rainbow boasted, knowing full well that she couldn't. Well, technically she could, but she would almost definitely cause a Sonic Rainboom in the process, "But that was good."

Zecora's 'spell' must've really changed your wings if you were able to have that much control over them.

"So are we ready?" you asked, quickly recovering your stamina as you prepared yourself for the Double Rainboom. You were determined to get this done, whether it hurt you or not.

"Don't you want a break first?" Rainbow asked, worriedly. At this point, she was more nervous about the Double Rainboom than you were. Seeing you pass out like that must've really gotten to her

"Nah, I'm fine." you said, panting a little. You defineoty hadn't fully recovered your stamina, but it was good enough, "Are you nervous?"

If Rainbow Dash was going to try and persuade you to have a break, you were gonna persuade her otherwise.

"Nervous? Me? Do you even know who you're talking too?" she asked, boastfully.

"Um... You?" you said, sarcastically. From the amount of time you had spent with Rainbow, you had learned that one sure fire way to get through to her was via her ego.

"And you think that I would get nervous over a rainboom?" she asked, maintaining her boastful attitude.

You simply nodded your head, and that proved to be enough. Sometimes, your actions could speak louder than your words.

"Well I'll prove you wrong, Storm!" she exclaimed, flying up above her house, "We're gonna do the Double Rainboom right now!"

You see? Using her own ego against her works every time. Well, almost every time.

"I promise not to pass out this time, ok?" you said, reassuringly as you followed her up above her house. Rainbow turned too you with a thankful smile.

"You'd better keep that promise." she replied, warmly. Something about the way she smiled at you made you feel... safe. You were about to attempt to perform a stunt that had never been done before, and you felt safe.
You couldn't explain it, but just looking into Rainbow's eye made you feel safe as a whole. Was it the work of magic? Who knows, but right now you had a Sonic Surge to create.

"Sooooo... Are we gonna do this or what?" Rainbow asked, snapping you back to reality. You didn't realise you had been staring at her for a while.

"Huh? Oh, yeah, right." you said to yourself, getting a giggle from Rainbow. Nevertheless, it was finally time to achieve the impossible. Or at least, it was impossible at the time. Most ponies never thought another pony would ever be able to do a Sonic Rainboom.

"On the count of three..." Rainbow said, preparing to countdown. The two of your unfolded your wings, preparing to takeoff at an extreme speed.

"1..."

Usually, the countdown would start at three, but you weren't going to question it.

"2..."

It was now or never.

"3!"

And with that, the two of you shot off into the air at a remarkable speed. It felt like the air itself was bending around you as you rocketed upwards, matching Rainbow's speed.

As you sped upwards side by side, the two of you glanced over at each other, giving each other a confident smirk. This time, you weren't giving up so easily.

Upon reaching a desirable height, you stopped flying upwards. Rainbow copied this manoeuvre, allowing gravity to rotate you around much like usual.

Instantly, the force of gravity began pulling you down, but unlike your previous attempt, you didn't start moving your wings.
Rainbow glanced over at you, confused as to what you were trying to do, but copied you in order to maintain synchronisation. If this was to work, it was important that you stayed at the same speed.

After falling for a few seconds, it felt like a good time to start flying downwards. With a single powerful flap of your wings, you shot forwards.

"Woah!" you heard Rainbow say, before repeating the same manoeuvre. The two of you shot forward like bullets, the all too familiar vapour cones forming around you.

Both yours and Rainbow's cones began to merge, mixing into one larger cones as it pulled the two of you together. Last time, this was where you gave up.
This time, you didn't intend on giving up.

Side by side, both you and Rainbow pressure the cone as hard as you could. You could feel it about to spring back and launch you intimate the distance. Even Rainbow looked like she was struggling.

But thankfully, you pulled through. In a satisfying moment of relief, the cone shattered, allowing the two of you to fly freely once again.
You were too relieved to have actually pulled it off to even bother looking at the sky to see what you had done.

"Storm! Look!" Rainbow gasped in amazement, staring at the sky with a sparkle in her eyes.

You had never seen anything like it. Not even in the TV show. Nothing as beautiful as this had ever been witnessed before.

Rippling through the sky in a wave was a rainbow coloured shockwave, but each second bolts of yellow electricity shot out of the rainbow. Above that was a smaller shockwave; this shockwave was coloured grey, much like your coat. This grey was incredibly dark, almost making it look black.

The secondary black shockwave contrasted nicely with the multicoloured wave of the Rainboom, sending beautiful sparks of light down towards the ground. It was incredible.
What were the other's going to say about this?

"Y'know, Storm," Rainbow said, breaking the silence. She still remained staring at the spectacular shockwave, "I think you're ready."

That confused you a little. As far as you knew, the two of you had just pulled off the impossible.

"Ready for what?" you asked, nervously. If anything could top that, then it was bound to be good. Rainbow gave you a mischievous smirk.

"Remember that race we planned a while ago?" she asked.

Oh great. Of course you remembered. You had agreed to race Rainbow Dash, but at the time it was called off due to you inability to fly.
It was bound to eventually happen, anyway.

Seeing the panicked look on your face, Rainbow chose to respond to herself. Even after pulling off a Double Rainboom, the thought of having to beat Rainbow Dash in a competition of speed still worried you.
What if the spell on your wings wore off?

"But first, we need a crowd!" Rainbow said, before speeding off towards the town of Ponyville. How was she not tired out?

Either way, this was going to be... interesting.

Author's Notes:

I wanted this chapter to be over 2,000 words, but I also knew it would end up being a someone short chapter. Getting it to be this long was quite a challenge, and in the end it's still only barely past 2K.

Nevertheless, the next chapter might take a while longer to write. Either that, or I find some more time to write. The next one should hopefully be a longer one
