Where can I share a longer ballbusting story?

I've never written out a story, but I like writing and wanted to do something different. I just spent a bit writing out a story but it's 6 pages on my Google docs and is obviously too long to just post on here. I don't want my info out there as this is my Alt account, so I'm trying to find a place I can share it that will allow me to not reveal my personal details.

Thanks!
