As mentioned above, this is an old story I wrote back in 2018 in a /d/ size thread. The cover picture inspired this silly little greentext style story, and we can consider it to be the earliest incarnation of Lillian, from my "Giantess/Shrinking & Farts" interactive, my personal favorite character. This makes her the oldest canon character made.
I can't say this holds up so well to my current standards but I don't hate it, even though most artists tend to cringe or be embarrassed at their older works. I think it's nice to remember where we came from and how far we've come from there, but I'll let you guys be the judges of that.
