A husband with a cuckold fantasy takes his wife to a photo studio under the pretext of preserving beautiful nude portraits of them together. A younger male model is suddenly brought in as a substitute, and she poses nude with him while her husband watches. Though hesitant at first, she begins dripping with arousal as their bodies touch and she feels his warmth. The thrill of exposing herself to a man she just met, combined with his unmistakable desire for her, gradually breaks down her fidelity.
