I wrote this in a previous thread:
Kara: Engages in it, but doesn't particularly prefer it over any other position.
Babs: Reluctant at first, but once she takes it all she goes full power bottom.
Jess: Has trained herself for it, but has never actually HAD it.
Diana: Takes a dominant role and will return the favor. Bring lube.
Zatanna: Already a power bottom. She will not let you pull out.
Karen: Faints the moment the tip goes in.
