Okay that is indeed a very thight one.
In fact, can't think of anything on top of my head. And I'm not sure I've even seen that (aside from maybe one shots).
"Our journey to lesbian motherhood" is autobiographical, and thus pretty grounded. And it's about, as the title states, a couple becoming mothers so it might interest you.
Though it's not exactly what you're asking for, you might be interested in "Collectors" by Nishi Uko. Established couple and it's more grounded, not on the very moe cutesy side of things.
"The Two of Them Are Pretty Much Like This" by Ikeda Takashi also follows a couple, a bit cuter than Collectors, but not too much IIRC.
Hey Collectors looks right up my alley!^^ Too bad they don't actually get officially married but whatever, the dynamic is more imporant!
You might like Wife and Wife. Technically not married, being set in a time where this just isn't possible for a lesbian couple, but otherwise considering each other wives anyway.
To help with that, is what you're looking for in the story:
a) The dynamic of a married couple, as in a story of a established couple that has settled with each other long term. At >which point something where the character are not married on paper, but are for all intents and purposes would interest you.
or
b) The official statute of marriage itself being a prominent theme that is brought up and discussed or commented on in the story?
I was thinking of the latter, but I'll take the former too since I know the picking's slim. I like what I saw in Wife and Wife even though they're not legally married (though I don't think I can continue reading it since the art style creeps me out. It's those eyes man ^^" also the story and characters are a bit too CGDCT-y for my taste)
I don't really understand why they really need the sperm donor to be a part of their and their child's lives. Won't it make the child feel less like theirs?
Just from seeing the short haired girl, I can kinda guess that this was drawn by someone who primarily draws BL, but seeing that dad pretty much confirmed it lol
Stories about childhood friends who grew up together just come off to me like the author wants to write incest but is afraid of the stigma. This may just be me but I don't think I can be attracted to someone I've known since childhood
So does the word 'yuri' mean something else (other than the flower) in Japanese? Or is the author just mixing up 'subgenre of romance involving wlw' with 'being in a relationship with another woman irl'?
This reminds me of that joke where a guy's best friend died before the guy's wife gave birth. The kid grew up to look a lot like the best friend and the punchline had something to do with reincarnation lol
