Karen's suspicions, however, were confirmed several weeks later when she had to go into the office on a Saturday, at the last minute, to finish an urgent presentation for Monday morning. The kids were at her parent's house and Mike was out of town for meetings. As had become a habit, she starting watching her nanny cams as she sat at her desk. She saw Sarah enter her walk-in closet and pick the complete outfit Karen had worn the previous day from the laundry hamper. Sarah then moved to the bed and undressed herself. She slowly slipped on Karen's dirty panties, stockings, skirt and blouse. Then, she walked over to Karen's shoe rack and slipped into the pair of open toe heels Karen had worn too. Sarah was obviously paying attention to Karen in the morning. Karen became acutely aware of her own wetness as she watched her nanny.
Sarah then stood in front of the full length mirror and admired herself in her boss' outfit. Then, as if realizing she missed something, Sarah strolled over to Karen's dresser and gave herself a few sprays of Karen's perfume. Karen was, once again, humbled that such a beautiful, young girl had picked her as an object of desire. After admiring herself some more in the mirror, Sarah went to Karen's hidden sex toy collection in the closet. Sarah selected a medium sized smooth vibrator, switched it onto high, hiked up her skirt, slid the dirty panties aside and pushed it all the way inside her pussy. Karen was so happy that she opted for the cameras with HD audio because she could hear the faint hum of the vibrator buried deep in Sarah's body. As Sarah strolled back to the mirror and was straightening out her skirt, she was suddenly startled. Karen heard it too, the garage door below the master bedroom opened. Sarah quickly made her way to the window and saw Mike's car waiting to enter the garage.
In that moment, Sarah must have decided it was time to risk it all. She went to the bed and laid down on its face first with a pillow under her stomach, let her feet hang off the edge of the bed and, in a move that impressed Karen, let her heels dangle impossibly off her toes. Sarah's body was writhing under the relentless hum of the vibrator inside her. It hit Karen that, as she looked at Sarah lying on the bed in her clothes and wearing her perfume, Mike could easily mistake her for his wife. Was that Sarah's plan all along? It seemed to be. Karen found herself anxious to see this unfold before her eyes, her pussy completely soaking her own panties.
Mike found it unusual that Karen's car wasn't home. He wasn't aware she had to go into the office, so he figured Sarah must have borrowed it. Nothing out of the ordinary. Karen could hear Mike calling for her and Sarah just let out a loud moan to betray her location. After a few minutes, she saw Mike enter the bedroom and, upon seeing his wife lying on the bed with what had to be a vibrator running inside her, he set down the roses he was carrying and slipped out of his clothes. How sweet, Karen thought, Mike wanted to surprise her with roses and not having to work, after all.
