The "Smut" tag is misleading.
This is a slice of life manga...
Sex happens, but nothing explicit is depicted... and while there are nipple shots, 3/4 of them directly relate to breast-feeding babies... so... yeah.
The fact that the main female has a fertility-goddess level figure might also be misleading (and the rest of her family aren't far different).
I had to lower my personal scoring a bit because the mother character hogs the story almost constantly like a malignant cancer. It would have been much better if she'd just hidden away into the background like the father.
@AidanGillen : I presume you're talking about the mother. If you're talking about Hinata too, I'd find it weird if anyone didn't find that attractive.
