How do woman know I staring at there ass

Do there have Eyes on there Ass? If can't look back how do there know.

If you have to ask, I can't possibly explain it to you.

Maybe it's because you're staring at their ass when they turn around, women are use to looked at like sex objects, many use it to their advantage

Maybe they can hear the heavy breathing.

The cat calling ????
Wow nice ass, they'll look

Probably because you were staring at their tips before they walked by. Then your Lazer focused attention did not realize they turned around to watch your head on a swivel Lazer in and focus on their ass.
