How does Milan Kundera use imagery in The Hitchhiking Game?

The scene below illustrates the girl's feelings, as she is a part of the game, as well as the discomfort she experiences when she realizes what she is doing.

She had never undressed like this before. The shyness, the feeling of inner panic, the dizziness, all that she had always felt when undressing in front of the young man (and she couldn’t hide in the darkness), all this was gone. She was standing in front of him self-confident, insolent, bathed in light, and astonished at her sudden discovery of the gestures, heretofore unknown to her, of a slow, provocative striptease. She took in his glances, slipping off each piece of clothing with a caressing movement and enjoying each individual stage of this exposure.

But then suddenly she was standing in front of him completely naked, and at this moment it flashed through her head that now the whole game would end, that since she had stripped off her clothes, she had also stripped away her dissimulation, and that being naked meant that she was now herself and the young man ought to come up to her now and make a gesture with which he would wipe out everything and after which would follow only their most intimate lovemaking. So she stood naked in front of the young man and at that moment stopped playing the game. She felt embarrassed, and on her face appeared the smile that really belonged to her: a shy and confused smile.
