How do I ask?
We were standing in a crowd full of people and were needing to regroup since we had split but we weren’t too far from each other. Well as we were about to leave my SIL almost backed into me (I put my hand on the backs of guys and on the hips of girls before they almost trip over me) so I put my hand on her hips and touched her ass since she’s actually really hot. While doing so she backed up to me as if we were actually together. So basically how do I ask her if she’s into me? And should I try to and we not speak about it if it happens?
