My suggestion is, that if she wants to "talk" about what happened, you just give her a call and set up a time for her to come over, or for you to go to her place (I would try to choose the location based on where you think she will be most comfortable having sex.) Personally, I feel that if what I'm reading is true, and you two are in privacy when you have this "talk" it will probably immediately turn into more sex, so long as you time it right, and keep the conversation short
As far as the conversation goes, I would try to speak very little in the beginning. People are uncomfortable with silence, and will continue to speak to fill it. Let her talk until you get something you can use, as you will either A) Find out she wants to be in a relationship with you, which you can then say I feel the same way, or B) she will say she doesn't want to be in a relationship in which case you can say something like "whoah, yeah I agree. I hope that us hooking up didnt give off that impression" - and from there you just make her into your fuck buddy. Which- then is pretty easy to turn into a relationship if you know how to work it correctly.
