Why does my wife often tap her boobs like a fidget?

Why does my wife often tap her boobs like a fidget?

She just walks around and taps both boobs just above and to the side where this girls hand is. Smiling and enjoying herself but made it clear only she is to do this!

This seems to be a habit she just got and wants to do alone for her happiness.

Sometimes she hits then pretty hard but she is still really enjoying herself and smiling. Sometimes looking at me and making a point of hitting her boobs. With her evil smile!

She is tapping a tune on her chest to a song stuck in her head. It's not adjusting and not a bad bra!
