Apparently, mamas who look like busty little sisters are the most dangerous mamas.

Maybe a translation sometime, not as high on the list as other stuff though.

I wanted to know who is the artist of this work.

Base +5

Lobo Branco: The readme mentions "Copyright studio b.p.p & kia" so it's possible the artist's nick is kia.

Their official profile page for the circle is also pretty spartan, only mentioning they're male, live in Kansai, and what they use to draw. Even there it's "Copyright studio b.p.p and kia."

So your guess is as good as mine.

His mother is a loli. That should be included.

Base +6

Cridel: Last I checked, for the most part lolis are incapable of producing children.

She might be rather short and resemble a little sister, but she is a woman, not a loli or even an oppai loli.

这种画风和故事也蛮不错的！

I'm surprised the artist hasn't been added for such a long time.
