A good (domestic) girl.

"So...do you want the bed or the cage?"
"The bed."
"Ask me nicely. Say that you'll be a good girl."

Ariel knows that this won't end well for her.
Why fight this battle, lose and have to still fight the next one?

"I'll be a good girl...Master."
"Let's hope so. Come inside."

She does so, entering the Kitchen behind you.

"Make me a nice dinner- like this."

You think of what you want and it appears on top of the stove.

"Now let's set the table...by hand."

Ariel looks at you, but will have to do it.

She is your domestic servant.

She makes no public complaints.

She watches you eat, since she doesn't need to.

When you're done, you tell her to do the dishes.
She obeys.

Ariel liked when she granted a few wishes.
Maybe got a little dirty.
Then she moved on.

Now you're taking full control of her and making her do what she normally doesn't do.

"Say- you know any other Genies?"
She nods.
"If you got another one to help you out, there would be less work for you.
Well, I'm going to brush my teeth."

You've planted an idea in her head.

You undress for bed and invite her to lay there with you.
You leave her collar on.
