Looking for a certain story

hey can anyone help me?

I'm looking for a story...two actually

the first is one that I thought I saw here about a guy who has a futa for a mother, he also finds out that his grandmother is a futa and at the end all three have an orgy

the second is one I saw back at the old 0bsidian site

it was a fantasy tale about a futa being rescued from a basement and the traveling around with a woman

eventually they both become futas but are executed as witches at the end

any help?
