Nicky watches you drink the cup with a smile that grows the further you go. It's refreshing, at least, even if you can't help but feel a little tingle as it goes down.
"Thanks," you say, but Nicky puts a hand on your wrist, still smiling.
"I think you should finish the rest," she says with a wink. "Every drop."
It doesn't even register to you to doubt her. She says "you should finish the rest," and you don't care one bit that there's still quite a bit of soda left in the cup. You chug it down, watching as Nicky takes a step back and grins. Why are you doing this? Why are you shaking the cup over your tongue, trying to wiggle the final drop free from the bottom of the cup?
As you're scraping the edges of the cup with your tongue, you hear the door open. "Hey Nicky, did the mark find the bottle?" a voice calls--Nicky's best friend Sara. She crosses into the room, eyes locked on you--she's well over six feet tall, and the second she sees the cup in your hand, she smiles, crossing closer to you. "Oh, wow, you don't waste any time, do you?"
You stare down at the cup, turning it over, in part out of confusion, in part to make sure there's nothing left in it. "W-What are you--" you begin.
"Quiet," Sara says, and you immediately clam up. You don't even want to finish asking what's going on. Sara has told you to be quiet, and you obey her, without question, instantly.
"Yeah, I'd say it worked like a charm," Nicky says with a smirk, wiping a little wet spot on the side of your lip with her thumb--and placing it right in your mouth. You immediately taste the soda on her thumb and lick, not even needing to be told. "I thought it'd take a while to take effect, but, wow, look at that. Right off the bat."
"Wow, that's amazing," Sara says, running her fingers through her red hair. "Oh my gosh, I'm gonna tell it to do something it can't normally do."
Nicky, five feet tall and gorgeous, leans into Sara, staring up into her eyes. "I know what you want," she says. "Do it."
Placing a hand on your chin, Sara tilts your chin up. Something inside you tells you that you should run, but you can't--Sara has locked eyes with you, and you watch with bated breath as she says...
