This choice: A genetic mutation.  •  Go Back...
Chapter #3

A genetic mutation.

    by: SmutScrawler Author IconMail Icon
They call it hermaphroditic hyperplastic gigantism... At least I think. My little sister (I'm 16)was diagnosed last year and so far things haven't been too weird, but her main drug treatment has failed and they're worried she'll start blowing up any day now. As for me, I just hope things stay pretty normal around here. As of today I'm 6'0" and she's like 4'something like her classmates. They were only able to diagnose her because of her uh... Growth last year.

You have the following choices:

1. Your sister grows fast

2. Slower
