Getting in trouble.. well, nearly

I have this crazy thing I like to do, and I am not sure why, but when I go on hikes I like to expose my breasts, but only when nobody can see them.

I mean, nudist beaches are the best, but sometimes exposing my titties where vanillas are walking excites me far more.

I have shirts with cutouts especially for this, and I wear a jacket over top that covers them.
My breasts are small, A, and I am not a heavy lady either lol. but I think they look nice and so does (did) my boyfriend.

So today I was out on a long hike around a lake. Lots of trees and a well trodden path. Was a beautiful sunny day, and it was just me and my dog.. so I let him off the leash and I listen for anyone walking. I can see a long way down the trail and I know there is nobody, although I suppose someone could be hiding behind a tree or something, but that has never happened.. anyways, when I feel comfortable, I just open my jacket and pull it around behind my back and snap the bottom snap back there, and my breasts are fully exposed.
I then walk the trail, my eyes scanning for any movement, listening. It is so exciting, I have a hard time describing it.

I have nearly been caught a few times. Someone will appear around a corner and I turn quickly, fixing my jacket to cover and then continue down the trail past them. They are usually focused on my dog anyway, he is kind of large and looks a lot like a black bear.

I wonder if they can see my pink cheeks or notice how I fuss with my jacket.
What would they think if they saw me like that?
