How many IOI's did you receive and what were they? If you are conservative, wait until she gives you at least three IOI's first. Also, you need to qualify her first, get her to invest in the interaction. Ask her: 'what makes you different?' or some variation thereof. She needs to give you a reason for you to be attracted to HER, aside from her looks. After you qualify, you can run a kiss routine.
Also, you can escalate kino during the attraction phase: does she squeeze your hand? How does she react if you rub her back? Does she touch you back? Sometimes, I will accidentally graze her breasts or run my hand along her leg if I feel the vibe is right first.
