Chapter #4

'Little' sister.

Original Author: TheMM

As you were thinking who exactly to test out your formula, fate decided for you.

Melissa, your younger sister of 16 walked right into your room and asked, "Hey, what's that?" But before you could make any sort of move, she snatched it from your hand and drank the whole thing in a single gulp.

"No! You shouldn't have drunk that in one gulp! It's incredibly potent." you cry out, even though it's far too late. Of the few things you did know about it, this stuff was certainly not met to be taken in such a massive concentrated form.

"Why?" she non-chalantly replied.
"W-Why?! Because nobody would know how big you might get!" you respond, trying to get Melissa to understand what she had done.
"Bigger? So I'm gonna get taller?" Melissa asked, "Like how tall?"
"I don't know. But you still shouldn't have done that. You might end up thousands of feet tall, if nothing more!" you continue, but this news actually makes her happier.
"Wow, thanks! I always wanted to be a giantess! And you just did that for me 'big' bro!" said Melissa, who then doubled over in pain. "Looks like it's startin...You might wanna get outta the house."

You quickly follow her advice, and leave. Soon enough, you see body parts of your younger sister push up against windows, then burst through as she out grows the house. Getting far too constrained, she simply stands up, destroying the entire building and already 100 feet tall. But she was by no means finished growing just yet.

Finding you and picking you up, you noticed that somehow her underwear had survived and were growing with her. That was weird, but then again, you had never expected anyone to drink the whole thing. Sighing to yourself, you wondered just how big she was going to get.
