Great first story! I love the it when young people are the focus of mini/gts stories. You did a great job. I'm not particularly fond of the giant aspect or all the cock talk, but to each there own. It worked for what you were doing with this story. 

I also must say. It was a pretty big tease to have so many other well described and developed characters not experience any growth. I was hoping at some point Riley or her sister might grow a bit. But that was just my personal taste and didn't distract from the story. 

It seems like you have something going with the strength shampoo story. I think it's off to a good start and if you can add young and interesting characters that story will be a hit as well. 

You're writing is great and can only get better with practice. Thanks for the story! W
