I really don't want to get into this, but sperm donors are completely legal, very common for both straight and lesbian women, even in couples one of them can choose to carry the child and its very simple. And on a threesome, no, its not just cheating, they are both lesbians and they don't want to have sex with a guy.

On Sara and Ava, neither of them seem to be people who would want a child so the point is almost certainly moot.
