"She then asked what else I had been taking pictures of (eluding to when she sent me pictures of her a couple of weeks ago). I just told her that I had taken some pictures but never said I sent them to her."
Just making sure I understand, so she was eluding to the nude or provocative photos you and her sent back and forth right? basically flirting again?
If so you handled that perfect! Just like as if a friend you were not sexually interested in flirted with you. You side stepped it. Boy I bet she was wondering why you did not take that bait.
