This last Saturday I was out with my friend and we went to a club. While standing in the line there were two girls that were standing behind us. They started with asking us about the music that they play in the club which I believe was just an excuse to start conversation since they were local as well. They told us that they are cousins. While one was hot other was not so hot ( I don't believe in measuring people on scales). Four of us had a nice conversation for almost 15-20 minutes during which I flirted with them a bit. During this time they were laughing, telling me that I am funny, all in all we were enjoying our time. Once we were inside it completely changed. I grabbed a drink and went to the dance floor to enjoy my time and after some time they also joined the dance floor. At this time I am with my back toward them looking at some other girl. The hot one starts massaging my shoulders from behind and so I turn to face them and they are completely avoiding any eye contact. This goes on for five minutes during which we are dancing together and they are still avoiding any eye contact. Then I turn again to face another side and then again she puts her hand on my waist so I turn again. During next one hour they are avoiding any eye contact but still touching me. I slap her ass few times while she is dancing with another girl but there was not much physical contact. After sometime they leave, I follow them and ask if they are leaving to which they say yes. I ask her if she wants to exchange numbers to which she says no. Me and my friend bid them farewell and part our own ways. Still confused what happened?
