Never Stop

Rainbow Dash knew she shouldn't but she couldn't help herself. She had gone three long, hard days without a toot of cocaine. Her friends knew it, but she wouldn't accept it- Rainbow Dash was addicted.
They found out when her house was seized on drug charges. It's a bit hard to explain your needing to move in with Fluttershy and your name is in the paper for possession charges.
She had to figure out a way to get that high without giving herself away. If she kept going off to the old abandoned construction site where the dealer dealed, somepony would notice. Then it came to her- get a whole bunch in one go, and stash it in a secret spot, so she would only have to go every now and then.
So, that night, Dash snuck out of the house (Fluttershy snored with the volume and forcefulness of a fart that you hold in and it does some rumbly thing in your colon) and flew off to the site. Around this time she started to think about where she would keep her stash. Eh, she could just shove it up her asshole like those guys you see on the news.
Sure enough, Zippy the dealer was there, expecting her, as usual.
'Where ya been the past few?' She asked as Dash landed beside the black Lincoln.
'Oh, uh, I've been trying to quit', she admitted.
'Well why would you want to do that? You wouldn't get to see ME'
'Sorry'
'Ah it's ok, the usual?'
Dash thought for a second (a sober brain was hard to get used to) and said, 'Actually, I would like to take as much as I fucking can,'
'Okay' came the answer, and she pulled a tray of bagsout of the car.
Rainbow Dash had never seen that much coke in her life. She guessed 120 bags in that tray! She quickly did the math, based on the usual sizes of Zippy's bags (quarter ounce) and holy shit that was almost two pounds of the finest cocaine. That shit would last a couple forevers for damn sure.
'How much for the tray?'
'For that, ehh... What you say to 45K's?'
45K's?! Dash had brought her fucking life savings with her- 1,000, enough for only 5/8 ounce by those prices.
She knew Zippy was easily pissy and wasn't sure how she would react to the fuck-nothing she'd brought, so she just said, 'Nah.'
Zippy looked at her, and thought aloud, 'You want more, don't you? 30 ounces just isn't enough for the supposed quitter.'
She turned around to get another (ANOTHER!) tray out of the car, and Dash took her chance. She grabbed the tray, took off, and hauled ass out of that fucking site.
What was she thinking? She just stole almost $50,000 worth of cocaine from a highly respected dealer, from right under her nose!
Zippy probably had four body guards there, with their AK47s, should somepony pull something. And pull something somepony did. They were all probably in the Lincoln, or in separate vehicles. She had seen once a Knight XV, a prestige armoured SUV. Google it, it's fucking badass. They would be looking for her and the coke, mostly the coke, she was just a nuisance, a fly on Zippy's burger.
They would find her. Zippy had told her stories about tracking ponies down and mutilating them when she suspected them of stealing an eightball or two.
She had no idea if they were true, but she only wished she had remembered those stories before fucking off with an assload of the shit.
Her thoughts were interrupted by gunfire. Sure enough, they had already found her in under a minute, and were following in a new car- a Dodge Hennessey Viper. Maybe around 2000 horsepower. Dash didn't give a flaming dog shit in a brown paper bag about what the thing was powered by, she could only bring herself to care that it was going fucking FAST. Keeping up to her for sure.
She climbed higher to escape the range of the gun, when she noticed another car coming along. This one was the aforementioned XV; it was having a tough tine keeping up to the Pegasus but Zippy and her .50 cal long-range didnt seem to care. Dash could hear the bullets fly by her, one blew a hole in the tray, almost causing the loss of a quarter-once of coke. Thank god it was near the edge, she thought.
She desperately kept climbing, till she must have been 4000' above the ground, in an attempt to evade the sniper. But the giant high-quality scope saw this only as a bit of a challenge.
The bullets still kept coming, stopping for a few heavenly seconds when the magazine emptied, but then starting quickly again.
The thoughts in Dashs head had gone from her stupidity, to what would happen to her, to what was happening to her, and had now come to FUCKFUCKFUCKFUCKFUCK
She just couldn't keep climbing. Shed run out of oxygen. De had to come back down.
So from her altitude, she slowed just enough to look for a hideout she could swoop into. Oh look, Rarity's house. Maybe she could just duck in there for the night.
So she redirected herself straight down, just zipping along, down, down, and she felt herself rapidly speeding up. Oh fuck, if she made a sonic Rainboom now, they could trace her right down to any remaining cells in her coked-up brain. She tried to slow, but it was hard. Eventually she slowed enough that the crash through Rarity's fucking roof only bruised and dislocated her front legs, rather than killing her.
When Dash picked herself out of the rubble, who should greet her but the pissed-off Rarity. Far from the elegant, high-class daytime version, night-time Rarity growled, 'Its 2 a-fucking-m, rainbow! What the nigger shit are you doing for fucks sake?'
Then she saw it. The heavenly, gleaming, white, cocaine.
That Rainbow Dash wasn't supposed to be fucking using!
Rarity grabbed the tray, and threw it at Dash.
She looked at Dash, stared right into her soul, and said 'Apparently you're not mature enough to be honest to your friends even if your life depends on it. '
Rainbow looked down at the floor in shame. there was nothing she could say, no excuse. She was fucking caught.
All of a sudden, there was another crashing noise. This time it wasn't the roof, it was downstairs being smashed at 2 a-fucking-m.
They ran downstairs to find a glossy black Knight XV polluting the air with biodiesel fumes, parked in the middle of the shop. Out came Zippy and her number one bodyguard, Bob. Both of them had Tommy guns. Well, Rarity and Rainbow Dash could not run, they'd get shot. They couldt surrender, they'd get tortured and shot. They couldn't fight, they get shot. In scientific terminology, they were fucked. There wasn't much time to decide, they had cuffs on them before either could communicate with the other.
Along came the Hennessey. And out jumped two more buffs. A couple rifle stocks to the face were enough to knock out Rarity and Dash, and into the truck they went.
