Tina slurps down her coffee, and almost instantly, Moe notices a difference. She's definitely getting taller.
He decides to say something.
"Hey, Tina, are you feeling okay?"
"A little over stimulated but otherwise fine. Why do you ask?" She replied.
Moe hesitated. Should he say something? Eh, why not. "You look...taller."
"Really?" She said. "Looks like somebody over there needs a bit more coffee. You're still in dreamland, buddy."
"No, for real, you're taller. Check it out. Stand up and compare yourself to me."
Usually, she came right up to almost Moe's chin. Today, however, she went all the way up to his forehead. Not only that, she was definitely wider; her shoulders were much thicker, her neck more defined, her pectorals more prominent.
"Huh... that's weird. Must have had a growth spurt."
"Yeah, but when you hugged me earlier you only came up just past my chin." said Moe.
"Really?" Her eyes were getting wider.
"I definitely remember that. Also, have you been working out more?"
Tina laughed nervously. "No, actually, I haven't worked out in weeks. I've been...distracted." She blushed. She was always cute when she blushed.
"Look at your arms, Tina," Moe said, somewhat seriously."
She looked down, and was shocked. "Holy moly, look at the gun show!" She flexed her left arm, gazing in wonder at the now meatier bicep. It had to have been at least 8" around now, much much larger than usual.
Moe then tells her about the article he read, about the meteor landing in the reservoir, and that their may be a toxin at work making her grow. Since she's been drinking coffee all night, the water from the coffee must be accelerating her growth.
Then Tina gets an idea.
