Late Strange Strut

I went to a dance class last night, and when I arrived the girl I was meeting ran up in a tight red dress and said hi excitedly. When we started cha cha dancing, she strutted around in front of me saying she was "having a moment". Later, she told me that she was strutting for me, and I "didn't react" at all. Then, she told me she was trying to make me "want her" but that I "could not have her". Later, we were standing around, and she pulled one of her breasts against my arm fairly tightly with her arm around my arm. She was wearing no bra since the dress was strapless, and I could feel her nipple erect. This was a MAJOR turn on as she did not pull away for minutes while we talked, but I tried to ignore this too. Later, she jokes about me masturbating and asks me. When I say I will not answer that question, she says the answer is yes and giggles and walks away. What the heck?? We flirt in good fun, but she never acts like this!!
