I absolutely have, but I haven’t had any posted online (there was one… once… but I took it down because it was unfinished for personal reasons and people kept coming around to badger me about finishing it and at this point I just try to avoid reminders…)
I’m actually writing a story that I hope to publish one day that’s vaguely g/t, and have plans for others!
And of course I’m obsessed with finding more stories to write, I love it so much and am addicted.
Non-supernatural gt is actually where I got my start! BA and the various AUs that nightmares and I have worked on together is actually some of the first fanfiction I’ve written at all (fanfiction was always so daunting to me). Other than the Food and Monsters series I have with Oscar the OC meeting the BA bros, I have a lot of GT material on my Deviantart page.
I do a lot of drabbles over on my writing blog (neonthewrite linked above), with some spn gt and some original stuff. In a lot of cases, it’s either drabbles with the characters’ canon sizes, or I’m messing around with size dynamics like making Jacob Andris a stand-in for Gulliver or having Bowman and Jacob swap sizes.
I’ve also recently published an actual GT story you can hold in your hands (what a time to be alive). That can be found here.
My main blog is actually centered around my first main series, which is a Doctor Who/The Borrowers crossover with an OC of mine as the Tenth Doctor’s companion. One day I will update/revise it ^^ Here it is on my Archive Of Our Own. On the blog I have a bunch of drabbles, shorts, and an AU or two that I have yet to fully explore but hope to soon.
(P.S. Neon and I have also tossed around ideas for a crossover with her novel and my silly stories x3 Preview here.)
