The Japanese word 'Futa' only means 'two', specifically used for counting people and people like objects. In the case of this title, this would mean Two Mikos.
The word 'Futanari' is a combination of 'Futa', or 'two', and 'Nari', usually meaning 'shape'. This leaves us with 'TwoShape', or the Japanese equivalent of hermaphrodite.
Hopefully this will help you distinguish titles before you are disappointed again.
