Are there not any lesbian storygames? I havent seen any
This story here has a lesbian path. It's not the only one, of course, but it is the one I would most recommend for you.
You seem like someone that’d be interested in the storygame I’m working on. It’s called “Choose Your Own Gender”. It’s not published yet because I’m finding it difficult to create several paths with only two choices and I still need to research mental disorders to ensure its factual accuracy.
You can be a big lesbian in Suzy's Strange Saga in some paths.
There are also these:
The title in the last one is a bit misleading, since "gay" typically nowadays refers to a homo dude, but you actually play as a girl in it. (Not really obvious though until it outright mentions it)
Actually now that I'm thinking about it, its not readily apparent that you're female in the first one either. Though the author was female and based it on her real life, so with that being the case, you're a rug muncher in that one too.
Thara's scifi anime inspired story for my romance contests was an epic lesbian romance tale.
Had school girl best friends becoming assassin lesbian lovers and everything.
Of course she unpublished it, so it's not available.
Working on a storygame with a lesbian protagonist. Does that count? mizal's seen some of it.
