The handsome German shepherd stretched his long sinewy body beneath his shining coat on the cool of the Winslow's kitchen floor, watching his new mistress, who had long blonde hair instead of the long black hair of Marge Levitt. It interested him to watch the sleek young housewife moving about her household duties with an air of feminine efficiency. He had often watched his older mistress with the same intenseness, and he wondered why she had gone and left him with this pretty, young, yellow-haired girl. He missed her terribly, but then he didn't presume. One always did as one's mistress directed.

Nor was he entirely unpleased with his new owner. Jan had tied her bright, copper-shining hair into a longish pony tail and generally fixed herself up. As was her usual habit when by herself, she wore just a very short miniskirt with thin filmy panties and no stockings, so that she could feel the coolness on her legs. She also wore a bright red sweater and no bra at all, so that her firm, heavy-set breasts shook and bobbled slightly as she walked. She had always been self-conscious about her breasts, because they were so abnormally large, and she didn't like to walk very fast, because of the way they shook and drew the attention of strange men's eyes. But with her neighbor's pet the only other creature in the house, she could relax and be herself.

Not that it escaped Rex that there was something not quite right about his new mistress. He sensed a certain indefinable dissatisfaction. Dogs are so sensitive to human psychology that Rex could not help but notice the indecision and general restlessness that seemed to characterize Jan's most inner thoughts, even when she appeared to be working at her greatest efficiency.

To Rex this usually meant only one thing: that his mistress would want to do it later. He often caught the same wave-lengths and sensual odor from Marge Levitt his older mistress, before they did things together, and previous to that he had sensed similar feelings in women around the neighborhood – before they had become too friendly and his absent mistress had tied him up and refused any longer to let him roam. Consequently the handsome dog knew what to expect, roughly.
