Take your time. If you care about her, let her set the pace for your relationship. Otherwise, if all you care about is that half-decent handjob and blowjob you got out of it, please gb2/4chan.
But seriously, give the relationship time. That's the only way to develop love and trust with somone with that kind of baggage; I should know. My girlfriend of ~2 years was abused by her father, a couple of times - I'm the only one she's ever told. That kind of trust doesn't come from a quick fuck, it comes from caring and just being there.
