It was a bright, sunny day in Ponyville, and all of the mane six were in Twilight's bedroom in her new castle ~~playset~~ home. They were having an orgy because they were all lesbians and totally hot for each other.
Rainbow Dash was taking turns with everyone else because she was the most lesbian and also the coolest.
Rarity and Fluttershy were doing bondage to each other, and Fluttershy tried to yell "Harder!" when Rarity spanked her, but she was too quiet and also had a ballgag in her mouth which muffled her orgasm screams.
Meanwhile, Big Mac showed up and immediately started having sex with AJ because they're southern and incest is what they do, even though he's gay and she's a lesbian. Eeyup.
Then Braeburn showed up and was mad because he liked Big Mac, but then he got over it when Big Mac finished with AJ and got on top of Braeburn. Braeburn loved being on the bottom.
Rainbow Blitz, who was Dash's gender-swapped counterpart was there too, and he and Dash fought for dominance. First Blitz won and he got to be on top, and then Dash won and she took him with a strapon.
Techno music played in the background, but the DJ was nowhere to be seen. She was actually still there, you just couldn't see her because she was busy eating out the prudish cellist behind the giant bass speakers. They were a very odd couple.
Twilight left to go into her private room and she was escorted by her favorite bodyguard, Flash Sentry. Nopony else seemed to like Flash Sentry, but that was okay because it meant Twilight could keep him all to herself. She liked him because he never talked and had no personality. And even though she was still totally a lesbian, sometimes she just wanted to take a break from it.
Pinkie Pie convinced Big Mac to do her even though he was super gay. She just had to remind him that she was probably technically a very distant cousin in the Apple family. She also said he could do her in the butt, and that was hot because girls who like anal are hot. Also, it meant Big Mac could pretend she was a dude while he did her.
All the way in Canterlot, at the royal palace, Princess Celestia was watching all of this through her magic telescope which she and Luna used to watch over all of Equestria. Celestia was dripping wet and she was clopping herself with one hoof while she watched her star pupil and all her friends having sex all over Twilight's new castle. The palace guards had a nickname for her—"Molestia"—because she would do things like this in all the places where she knew they would see her.
The two guards just inside the veranda where Celestia was already had raging boners as they listened to the very loud noises their princess made. But they were under strict orders to remain at attention so they couldn't do anything about it.
But then Princess Luna came by and she took pity on the guards and let them spit-roast her. Afterward, Celestia was bored of being a voyeur and she came inside just as the guards both came inside Luna from both ends. The princesses then went into their bedroom together and had lots of hot wincest while the guards had to stand at attention and watch again.
Recruitment for the royal guard was at an all-time high.
Rainbow Dash had to leave her friends at the orgy because she was the newest member of the wonderbolts, which had been her life-long dream, and she had a date with the Wonderbolts.
The date was in the locker room at the private cloud racetrack the Wonderbolts had. There, Rainbow Dash had sex with all the Wonderbolts. Spitfire was first and she sixty-nined with Rainbow Dash. They ate each other out until they both came. Then Sorin took over and he got on top of Rainbow Dash. She didn't want him to get her pregnant though, so when he got close, Dash made him pull out and he finished on her face.
Fleetfoot was next, and she started by licking all of Sorin's cum off of Dash's face. Then she scissored with Rainbow Dash. They rubbed their clits together until they both came and got each other all wet and sticky.
Rainbow Dash was getting tired from all the sex, but there was still one more Wonderbolt she had to have sex with. He was the coolest, most handsome member of the Wonderbolts, and not just because he had a massive dick and was also an alicorn. He was too cool for his real name, so he had everyone call him by just his initials: O.C..
As soon as Rainbow Dash saw O.C.'s penis, she was instantly wet and horny again, even though she was super lesbian. She couldn't control herself around such an attractive stud. First she sucked him off and swallowed his whole load. She was still horny after that though, so she let him mount her. O.C. came inside her and Rainbow Dash didn't even mind. She was even still horny after that, so she let him do her in the butt too because it was about the only thing she hadn't done yet today.
Meanwhile, back at Twilight's Castle, a human from the real world got somehow teleported to Equestria and he showed up right in the middle of the orgy. Everyone was surprised at first, but he didn't have any clothes on so he just joined in the sex with all the ponies. Everyone had sex with him, and they all said it was the best sex they'd ever had. And by the end of the day, having all that sex with magical ponies turned the human into a pony himself. He was totally okay with it because it meant he could stay where he was happy and popular and good at sex and could just forget about the real world where things weren't so awesome. And they all lived sexily ever after. The end.
