"I apologize but I'm confused... You wish to date me?" She scratches her head, you nodded in response.
"There are those who had wished to have sexual intercourse with me before, those who wished for me to be their partners as well.
You are not the first to ask me so, but you are first to ask me with such a new term."
Girlfriend? Really? Seems like an old term. People in medieval times used it right? Right?!
Maybe the Genie is just THAT old. You don't say it though on account of not wanting to offend her.
"This new term, that would mean that decades had passed correct?"
Your unsure. You didn't own this treasury and you certainly don't know how long the Genie's lamp is in there. So you just shrug.
"I will accept it as an answer. Very well then. I shall now be your 'Girlfriend'." With that, she snaps her fingers. The trail that her back followed into the lamp was cut, replace by real feet.
She hovers a bit before descending to the floor. You had just realized how taller your new 'girfriend' is than you.
"Master. Your second wish?" She asked deadpanned.
