This is basically my ideal futa doujin. Yuri, but one girl has a dick(maybe girl parts too), and nobody questions it. It's just perfectly normal. I love it. I guess you could call it an "acceptance fetish"?
Like, I'm not trans, but I imagine a lot of trans people who haven't/won't/can't fully transition(ed) wish for this kind of normalcy. It sounds like a nice world to live in.
