The story, Graduation Day, is based on the entry by user "Athletic Guy." I don't want to spoil the story for those that prefer a surprise, but feel free to read the contest winner announcement if you'd like read Athletic Guy's idea.
At the moment I'm still working on other stories, which I hope to post soon. I'll also have some other content soon, so stay tuned, and please let me know what you think of the story Graduation Day.
I very much enjoyed the idea of having a story contest and I hope I can do something like it again in the future. Thank you again to everyone who submitted an idea.
