Is she flirting with me?

Hey everyone So I told my friend I was bisexual a few months ago and then we decided to have a hot tub night. I was sat beside her in the hot tub and all of a sudden she quickly undid my bikini top so it came undone. I thought she was just messing about but she did this another 2 times. The music was also going and she was twerking towards me as well. So her bum was in my direction. We were both sober. We then went for a drive to take my son to work as my car is off the road at mo and her friend came as well. Once we had dropped her friend off we hadn’t even got round the corner before she said “ I would let you go In the hot tub but I’m cleaning it”. ( i didn’t have my bikini or anything with me and it had not even been mentioned). I found the behaviour a little strange. Any advice would be great thank you
