I guess it became inevitable when I created the almost-throwaway crossover between Step-Something and Bonds of Friendship that I'd want to take the idea further (as we talked about here and here) to make an "Expanded Universe" story.
Sometimes I'm sorry to say goodbye to a minor character in a story, and wish I could create a side-story just for them. In this case I had two characters from entirely different stories (Step-Something and Breakout) who were just perfect for each other. And it just happened that I'd already tweaked the universe of one, and since the setting of each (in a university town) could easily be the same, I yielded to temptation and introduced Margot, from Breakout, to Heather, who discovered her sexuality in Step-Something.
And on the way added a little more epilogue material for the couple who may be my favorite of all, Faye and Erin, of Bonds of Friendship.
It's just possible that there may be a link to a fourth independent setting hiding in the pages of Entanglement, the new story. Well, okay, there is, but whether it will ever amount to anything depends on whether the relevant side-story comes about. Inspiration hasn't struck yet, but I'd be interested to know who is able to identify who the protagonist will be if it comes into being.
As usual, the story took on a life of its own and became far too long, so I've divided it into many chapters, most of which have plenty of sexy encounters (and not all between the primary couple). And it's finished, but it's long enough that I probably won't be done proofreading until the coming weekend.
Edit: I fixed a few problems in proofing but there are probably more. Please let me know of any you find. Meanwhile, the story is up at Entanglement.
