She was wearing black stockings, with red-bottom high heels on her feet, right on the sofa.
The heels occasionally knocked against the floor, making faint sounds. The black stockings were stretched tight, and the red soles kept appearing during the movements, like a color that refused to be ignored.
There wasn't much foreplay, nor any extra words. The sofa was soft, her legs were forced wider apart, the high heels were never kicked off, just swaying gently with the rhythm.
After it ended, obvious traces were left on the black stockings, and the red-bottom shoes were still properly on her feet.
