"Twily, duck!"
Twilight Sparkle blinked in confusion but ducked anyway. She heard a thumping sound above her head and looked. A short, sharp dagger had lodged itself into the wall behind her, which was made of reinforced concrete. Right where my throat was a second ago... Twilight's eyes widened as she realized what had happened. She recalled the familiar voice that had warned her of the danger just moments before. Of course it had been him. Did he say Twily? Princess Celestia had also turned to inspect the weapon that had come flying toward them.
"What the fuck is that shit?" she asked in confusion. Twilight would have answered if she knew, but nothing quite made sense at the moment. She just knew they were in danger a moment ago and wasn't sure if it had passed.
"I'm coming, Twilight!"
Before the princess could turn her head, Shining had galloped over, shielding her from any potential harm with his own body.
"Shining, what's going on?" Twilight pointed at the dagger in the wall. "Was that..."
"We can talk later. There's an assassin after you!" He nudged her over to the corner of the room as Celestia barked out commands to the guards who had arrived in mere seconds of Celestia's command. Twilight protested, dragging her hooves on the floor.
"An assassin? Don't be a dumbass, Shining. If they're after somepony, it has to be Princess Luna," said Twilight.
"Why do you say that?" asked Shining, raising an eyebrow.
Twilight rolled her eyes and smiled. "Isn't it obvious? Everypony in Equestria treats her like a dumb bitch for a reason, you know."
"I would appreciate if you did not talk about my sister like that, Twilight Sparkle." Twilight exchanged a wide-eyed glance with her brother before turning around slowly. Princess Celestia stood behind her, wings flared and eyes narrowed.
"Celestia, Twily here wasn't talking about our Princess Luna! She was talking about, uh... you!" Shining finished lamely, shrinking back at the monstrous glare Twilight was giving him. Celestia's eyes flickered with silent rage. She said nothing for some time, leaving the room in dead silence.
"Twilight Sparkle, you annoying stupid fat purple piece of horseshit, you are hereby stripped of your title of princess," Celestia said coldly.
"What kind of stupid joke is that?" asked Twilight, staring back at the princess. She had served the royal castle loyally for years now. There was no way Celestia would get rid of her now.
"I SAID SHUTUP YOU PURPLE CUNT! You will leave. Now. Take your shitty ass brother with you too. I will marry Cadance myself to rid the royal family of you trash." Celestia nodded to the door. Twilight opened her mouth to protest, but Shining put a hoof over her mouth and nodded.
"We understand, Celestia. You won't hear from us again," he said. He leaned in close to Twilight's ear, whispering "I'll tell you later" as they walked out the door, surrounded by guards on all sides. Before they left, Shining turned back briefly. "By the way Celestia, Luna could use some work in bed. I fucked that pussy real good, but she was as good as a dead fish."
Celestia's horn glowed an angry red, and she glared daggers at the stallion. "I WILL FUCKING KILL YOU AND YOUR WHOLE FAMILY!" she screamed.
"TWILY, WE HAVE TO RUN!"
So they did.
"So how did you know I was in danger when you told me to duck?" asked Twilight.
Shining turned around, giving her a confused look. "I never said duck, Twily. I said 'let's fuck'." He pulled down his pants to reveal his massive erection. It was ten inches long at least, with a thick swollen head with a drop of precum that showed his arousal.
Twilight shook her head. "Wait a minute, I heard you. Right after, you said 'I'm coming' too."
"Yeah, I did say I was cumming. I was masturbating and walking in your direction as I orgasmed," he said in confusion.
"But what about the assassin?" Twilight's head spun. Had she misunderstood everything Shining had said? Shining looked at her as though she had lost her mind.
"What assassin, Twily? I said that I wanted to do your ass in with my dick." He stroked his cock, moaning slightly. "The offer is still on, by the way."
"W-What? Shining, that's wrong! You and I are..."
"Siblings?" he finished for her, sadly jerking his penis. He swung it in front of Twilight's face, precum flying off and landing on her lips. She gasped but licked it up anyway. "Look Twily, I know true love when I see it, and this is it. Just look at how hard you make my dick!"
Twilight felt a burning in her loins and found it harder and harder to deny. Before she knew it, she was sitting on her hind legs slurping up that massive penis like it was her job, and it might as well be now that they were no longer part of the royal family. "Oh, Twily! My penis feels so fucking good. Don't stop!" Shining moaned louder and louder, his cries only serving to arouse Twilight even more. She could feel her wetness pooling on the ground underneath her as she pleasured her brother. Shining's swollen dick twitched, and she could tell he was close.
Suddenly she stopped. Shining immediately protested, trying to shove his penis back into his sister's mouth, but Twilight ignored his efforts, instead getting up to position herself over him. "Shining, close your eyes," she whispered. Finally realizing what was happening, the stallion obeyed. Twilight slid on top of him and touched the tip of the penis to her wet entrance, gasping as sensations bombarded her. She was floating, and he wasn't even inside. Slowly, she managed to slide Shining all the way inside her, stimulating places she didn't know existed. "Fuck me, Shining!" she begged.
"A-Ah, got it Twily! Here we go!" he panted as he thrusted from the bottom, their sexes colliding. "OH FUCK TWILY, YOU ARE SO TIGHT!" Twilight heard his voice but was too lost in the pleasure to reply, only able to offer a loud moan as they continued to fuck. "TWILY, I... I'M CUUUUUMMINGGGGG!!!" Shining screamed at the top of his lungs as he let loose his huge load inside Twilight's vagina, unable to stop himself from thrusting even as the painful sensitivity in his penis quickly made itself known. He was hyperventilating now, his hips moving on their own. "TWILY PLEASE, I ALREADY CAME! STOP, IT'S TOO SENSITIVE. I'M GOING TO DIE!"
"I'M CUMMING TOO, SHINING! OOOOOOH CELESTIA!!!" Twilight screamed, squirting all over Shining's cock and exploding on his face. She bounced up and down on Shining's still semi-hard erection, ignoring his cries of pain as she continued her search for pleasure. Finally, they stopped.
The two siblings looked each other in the eye, resting against each other on the ground. They didn't have jobs anymore, no fallback for the future, but at least they had each other.
