Cousin made advances

So a cousin of mine from mexico came to visit us here in the states for a couple months. We’re close like most families and I enjoyed talking and hanging with her whenever I was in Mexico.
We arrived at my aunts house to eat and say hi. I see her and we smile at each other before I sit down to eat. While I was eating my soup I could feel her staring at me very intently. I just try to ignore the feeling and continue eating until I look up and catch her but I just smile at her. Didn’t think much of it but she continues looking at me until I get up and leave to walk around.
As more family arrive and I go to say hi and I see her multiple times giving me bedroom eyes. I start getting a little weirded out but I tell myself I’m being dumb.
They have music playing in the front of the house so I go out to check it out and people are dancing.
One of my aunts grabs me and drags me to the dance floor to dance before she hands me off to my cousin whose waiting for her turn with me. She quickly grabs me and presses her tits up against me hard with a big grin across her face as she looks up at me. We dance Like this for a song before she starts showing me how to move my feet. When the second song finishes I thank her and head back inside.
I was a bit freaked about it and avoided her for the rest of the visit. I can’t help to wonder what made her do this.
I wonder if she was ever secretly turned on whenever we hung out and were physically close. Like being in her Pueblo riding in the back seat of her motorcycle on the bumpy dirt road. Was she wet whenever I was pressed up against her backside with my hands held under her tits tied against her stomach or when we were alone at her house.
I draw the line at family so I would never but I can’t help to think why?
