Would I be using this person?

I have a relative that I never met or knew about until two years ago. She doesn't have any kids of her own and I guess she felt guilty about not being around when I was younger, so she's always asking if there's anything she can get me. She's a doctor by the way, so she has a lot of money. So whenever she asks me if there's anything I want I always say no because it would feel weird if I took advantage this. I'm graduating soon and she told me a couple of days ago that she knows that I never ask for anything but she really wants to get something anyway this time and wants to know what I want. The only thing I want right now is a retain game console. It's $300 and I've wanted it for a while now, but I don't know if it's going too far to ask her for one. Should I do it?
