Liar, Liar (ft. Twilight, Rarity)

The unicorn duo sat across from each other, two glasses of flavored soda water in front of them.

“Twilight Sparkle,” said Rarity, not a hint of compassion in her voice, “you are lying to me.”

“I am not,” insisted Twilight. “It was great!”

Rarity raised an eyebrow. “And you’ve done it again. More lying.”

Twilight locked eyes with her marefriend. “Rarity. Please, I’m telling you. I liked it.”

Rarity contemplated her for one, two, three seconds. Her horn glowed, and the glass closest to Twilight inched towards the lavender mare.

“Fine. Finish it, then. All of it.”

“I will!” replied Twilight.

“Do it, then.”

Raspberry magic enveloped the glass and floated towards Twilight’s mouth. “I’m doing it!”

Rarity inched forward, smiling pleasantly. “Less words, more drinking, dear.”

Twilight shot her a glare before bringing the rim of the glass to her lips and, in one swift motion, chugging the drink almost halfway before gagging and spitting it on the table.

“EUGH!”

“AH-HA!” declared Rarity victoriously, right after she’d finished yelping at being spat on. “I knew you lied to me! And so will everypony else at tomorrow’s gala when they realize you asked Pony LaCroix to be the only thing served just because you know it’s Princess Celestia’s favorite drink!”

“I’m sorry! I just—I need everything to go perfectly! And it’s not just her! Every noble likes it, and I don’t GET it! It’s disgusting!”

Rarity gasped, offended. “Excuse you! It’s perfectly delicious, and low-calorie!”

Twilight slammed her hoof on the table. “It’s spicy water, Rarity! Drinking water shouldn’t be spicy! It’s just not right!”
