You control enchanted player during extra turns.
Is there a reason you want to allow yourself to be enchanted with this Aura? If not, just change the "Enchant..." sentence to be "Enchant Opponent", like Psychic Possession.
As for the wording, do you want to take all their extra turns, or just the ones granted by the Aura? If it is the former, I think your template is fine. Just update it to this:
Curse of the Mindless 3UB
Legendary Enchantment - Aura Curse
Enchant Opponent
At the beginning of your end step, enchanted player takes an extra turn after this one.
You control enchanted player during his or her extra turns.
I think I'll go with this. I think it makes more sense for what I want to do here.

I'm really not sure if this would be the best wording for this. It's kinda like Timesifter / Lighthouse Chronologist and Mindslaver.
