TL;DR: Enjoyable but short. A great pure-expansion story.
I think this is a great story for this site. It may not be exactly what I am looking for as I enjoy a fair amount of story. That being said, for a story whose sole purpose was to show titillating expansion and raunchy daydreams this was spectacular. Your style is very easy to read and I can tell you're an excellent writer. All in all I did enjoy the story despite its unfortunately short length.
A few critiques though:
The characters were fairly simple although Suzy was quite likable. Once again though, it's in the context of a straight forward expansion story so the character depth doesn't really matter.
BE Description was slightly lacking. I didn't really have a feel for how large she was. Though I suppose that's the point as the reader is to interpret the vague sizes how they wise. Regardless, I would just recommend perhaps detailing small checkpoints she reaches. Her breasts are as large as oranges, then grapefruit, etc, etc. Though once again, as the story was short there wasn't as much space to really flesh out every minute detail.
My last critique is that it was too damn short! What was there was enjoyable but it does leave me with a yearning for more!
