The Queen Of Futanari
It is quite obvious that these past few days have changed her, but I have to remind her who I am so she can have the appropriate attitude toward me.
I give her a box and tell her that inside is the first crown that I have worn when I became the queen of futanari. What I do not warn her is that crown is magic, it might look beautiful, filled with diamonds, but the trick to it is that whoever wears it has to be worthy of it, as it reads minds and does magic accordingly to the behavior and thinking of the one wearing it.
I put it slowly on her head and tell her to wear it for the entire night, as she will have a surprise the next day.
