If a person likes you and attraction is already there for you, they should be asking you questions and trying to demonstrate their value to you. Try to answer their questions but do not keep waffling on answering logically as it will break down the tension. I would try to build some compliance by asking them some brief questions about themselves or yes ladders, then eventually questions like 'you're obviously very pretty, but beauty is very common, what are your 3 best qualities' which requires a high level of compliance on her part. If she answers any questions then you should give her IOIs/reward her. Try to fractionate as well, so like maybe you don't reward her once when she is showing her value/responding to you, body rock and seem distracted or something, she will work even for you. Another fractionation technique is to get her to tell you about positive experiences she's had, and then negative experiences she's had.
You can also tell them about positive experiences you've had, then negative in quick succession which builds a high level of intimacy and is emotionally addictive.
