It's like she's saying "Yes these are my breasts, this is what I look like topless. Satisfied?"
She's really not cracking that big of a smile. In fact, it's not much of a smile at all. Though, the more I look into her eyes the more it looks like she enjoys being topless in front of me; her being topless like this is also a show of trust and confidence in me to do her no harm. She also trusts me to handle myself as a man.
But I'm getting mixed signals from her. She looks like someone that you really had to convince to make this picture. She looks the kind where it wouldn't take much for her to put her top back on and then she walks out the door - never to do this again. I could also see her wondering what I'm going to do to her now that she is topless. I could see her wondering what she's going to get out of it after giving herself to me.
If I was with her by myself, I wouldn't trust her too much or get too lost in the moment with her. She's older and has been around, and it doesn't look like it would take much to set her off. She'd know how to catch me in a lie if I was a liar.
But her hair being all over the place and the fabric of her top really help to make her breasts look softer. This is still a nice picture to look at.
