pencil and story: Comes

Being in French, my understanding of the story is limited, unfortunately.
In a forest lives a woman with two men.
The atmosphere is slightly mystical and worshipers of an ancient religion, probably druids, are also involved.
One day a woman arrives in the forest, accompanied by an owl.
The woman who lives in the house becomes pregnant, but the pregnancy is complicated by the presence of the druids.
A priest also gets involved, who reveals some perversions regarding the pregnant woman.
Eventually the woman carries the pregnancy to term and remains to live in the forest.
The “Belette”, which in French means the “Weasel”, is obviously her.
Original drawings suited to the fantasy atmosphere of the story.
