What is she doing?

My sister has been trying to get me to visit her more often. I would except she seems to be very hands on with me. She has put her hand on my back while feeling my abs and a couple of times she fell down in front of me and stayed in a doggy pose for an extended period. I am getting a little worried she might be implying something but I want second opinions. Could someone explain to me what is going on?
