Damn brother, you may have something good going for you here, so don't fuck it all up!
First of all, you are ASSUMING that she wants to have a deeper relationship with you.
Second, you are acting as if you never want to bang her again.
Thirdly, you are acting like this, probably not because you didn't like her pussy, but you ASSUME that would continued sex would require a deeper relationship.
Why do you think that?
Friends with benefits is the way to go. This doesn't lower her or your moral standards. You two are friends, that like each other's company, and enjoy having sex with each other. Rather than going to different bars and picking up random chics to screw on one night stand and further drastically increase your chance of an STD, you two enjoy each other's company minus the emotions.
Explain it to her that way, let her know that it isn't that big of a deal... it's sex without the bullshit.
Male or female, we can all appreciate that.
Also, and this is a big point... one you may stress to her. The sex gets more wicked as time goes on. Much more kinky, much more comfortable... much better than a one night stand.
Friends.
