I like this shot as it has the air of a spontaneous snapshot. She’s got that look of someone temporarily dragged away from their task by some idiot with a camera. Like that annoying relative at Christmas who is always stopping the fun to ‘capture the moment’.
I’m sure it really is a posed shot. But I enjoy entertaining the notion that the second after the shutter clicked, she told the photographer to take a break and returned to seeing just how far she could get her hand into her boy’s ass.
