My sister hugged me topless, did she step out of line?

OK, it'd been several years since I've seen my sister and we agreed to meet each other at a beach, and when I got there she yelled hi!!! and all she had on was th bottom piece of her bikini (in the state we were in it's legal for girls to go topless). And if seeing my sister topless wasn't a shock enough, she ran over and gave me a long, tight hug (and I had my shirt off too). It made me feel really uncomfortable. I later talked about it to her and she said "I've seen and hugged you with your shirt off before too and it never made me feel uncomfortable." Do you think she stpped out of line doing what she did?
