Adagio, Aria, and Sonata, each with two bikini tops tied around their wrists, started to hang back from the racers to watch for their quarry.

Aria saw a male student with a phone standing nearby, and jogged over to him. "You there," she growled. "How many of the Rainbottoms are out of the race?"

"Rai-rainbottoms?" the student asked.

"She means Rainbooms," Adagio said, running over. Her chest bounced fetchingly in her dark purple bikini with black trim.

"Uhh..." He drooled a little as he stared at Adagio's chest. Suddenly, he seemed to come out of a trance. "Hey, you're those girls! The ones who started that Battle of the Bands nonsense! I ain't tellin' you anything!"

With a frustrated growl, Aria grabbed Adagio, spun her around, bent her over, and spread her ass cheeks wide. The gawkers gasped. Phones beeped wildly.

Adagio pushed Aria away and turned to face the crowd, crossing her arms under her chest. "What the FUCK, Aria?!" Adagio shrieked.

Aria put a hand in her face, sneering at her target. "You owe me for that," she said. "Now talk."

The student gulped, face red and hot. "Um...Rainbow Dash and Applejack are out. The rest are still in."

At that precise moment, Applejack and Ms. Harshwhinny walked past, arms around each other, waving genially to the crowd.

With a grunt, Adagio thrust her hand down the front of Aria's neon-green bikini bottom, made a fist, and twisted, dragging Aria behind her.

"OW! Dammit, Adagio, you're pulling on my pubes!"

"Then you should've waxed," Adagio said. "Come on, we've got work to do!"

Sonata bounced behind them. Aria's loud swearing filled the air in their wake.

Lyra, wearing a light silver bikini, and Bon Bon, wearing a two-tone pink-and-blue bikini that matched her hair, stared up at the bizarre sight they'd run across on the third leg of the marathon.

Derpy was hanging upside-down from a utility pole by her bikini bottom, which had somehow gotten tangled up around her ankles. Her lower torso was exposed to the world. Her bikini top was still firmly in place, and she was wriggling around, trying in vain to free herself.

"Derpy," Lyra said, one hand on her hip, "how'd you even get like that?"

"I don't know!" Derpy replied, her lazy eye spinning. "It just kinda happened!"

Lyra and Bon Bon looked at one another. Bon Bon shrugged.

Lyra walked over to Derpy and removed her bikini top, leaving her hanging upside-down and completely naked.

The two girls continued on their way.

Fluttershy stopped to rest, bracing her hands on her knees.

All around her, guys were cheering her name and shouting words of encouragement...and rather lewd suggestions.

She looked around, blushing. "Umm..." She poked her fingers together sheepishly. "You're...you're all very naughty," she said quietly.

"Strike ze pose!" a heavily-accented voice called. Fluttershy turned to see Photo Finish, one of the few girls who had declined to join the marathon, holding a very expensive camera and pointing it at her. "Vork ze magicks!"

"Oh...umm...I don't—"

"You vill be ze poster girl fur ze animal shelter!" Photo Finish declared.

Fluttershy bent low, thrusting her chest forward and her rear out. "Ah~n," she moaned, closing one eye.

*FLASH!*

Fluttershy stood with her legs slightly apart, arms stretched above her head, smiling.

*FLASH!*

"Yes! YES!" Photo Finish began to draw ragged breaths. "Ach, you beautiful buttery angel!"

Fluttershy blinked. "Umm...are you okay...?"

"More! Giff me MORE!"

"Umm...I...think you've had enough..." Fluttershy turned pink. "I go!" She turned and ran.

Photo Finish was too busy rubbing herself and moaning while staring at the back of her camera to notice.

Cloud Kicker let out a scream as she sprinted forward, hand outstretched to strip her target's top.

Trixie yawned, pulled another smoke bomb out of her ass, and threw it. The cloud of glittery blue smoke obscured her. Cloud Kicker passed through it, coming up empty.

Trixie's laughter echoed from all around her.

"Foolish girl! You're a hundred years too early to challenge the Great and Powerful Trixie!"

"Dammit, cut it out!" Cloud Kicker shouted.

Trixie leapt out of the crowd, over the cordon, and tackled Cloud Kicker to the ground. Cloud Kicker struggled and thrashed, but Trixie emerged victorious, the other girl's white bikini top held proudly in her hand. "Voila," she said, smirking.

The crowd cheered.

"Okay, you win...now will you get off me?" Cloud Kicker growled.

Trixie leered down at her. "After Trixie gives her audience something special," she said. She reached down and cupped Cloud Kicker's breast in her hand, fondling her. The spectators went wild, letting out cheers and wolf whistles. With an impish wink, Trixie drew another smoke bomb out of her ass and dropped it, sprinting away as the twinkling smoke exploded outward.

Sunset and Twilight caught up with Pinkie two turns later. There were deep, hand-shaped indentations in the whipped cream armor around her chest, and four bikini tops were tied to her wrist. They matched the bikini bottoms of four girls the two had seen stomping past them in the direction of the start line.

Pinkie turned and saw them. "Oh hey, you caught up!" She smiled. "Wanna play tag?"

"We're not gonna try to tag you out," Twilight said. "We don't think it's right for friends to go after friends."

"Even though that hasn't stopped all of us," Sunset added.

"Yeah, I saw Fluttershy go past a little while ago," Pinkie said. "She had Rainbow Dash's bikini top..." She gasped. "She got Rainbow Dash?"

"Way back at the start," Sunset said. "So Fluttershy's still in?"

"As far as I know," Pinkie said. "AJ's out, though."

"Yeah, we, uh...saw," Twilight said, blushing.

"There's got to be an interesting story behind that," Sunset said.

"THERE YOU ARE, RAINBOOMS!"

Sunset, Twilight, and Pinkie turned as one to face Adagio, Aria, and Sonata.

Sunset groaned. "Oh, good grief..."

"The Dazzlings?" Twilight asked.

"Yeah..."

"We've got a score to settle with you!" Adagio declared, pointing dramatically. "We'll settle for humiliating you in front of all of Canterlot! And we don't care about the rules...we're stripping you all completely butt naked!" She looked to her fellow Sirens. "Aria, you take little miss Princess. Sonata, you deal with the pink one." She narrowed her eyes at Sunset.

"Sunset Shimmer...your ass is mine."
