*****
Karen had returned from work at her usual time and immediately received a phone call from Jamie, her husband, telling her that he would be home very soon, too. The couple had settled into a domesticity that belied the origin of their relationship. Karen, now 26, as was Jamie, had been drawn by her neighbor, Jamie's Aunt Claire, into supervising Jamie when he came to live with Claire and was seeking a job.
Claire, now in her mid-30s, had made it clear to Karen that she wanted the younger woman to take charge of her nephew, who was sloppy and seemingly satisfied with being unemployed and at leisure in Claire's comfortable home next door to Karen's less grand residence. Her supervision would include, Claire had told Karen, monitoring of Jamie's intimate habits, including the bathroom, and the authority to discipline him as appropriate, including spanking and caning.
Karen had taken on the challenge and Jamie had shaped up, mentally as well as physically, and secured an excellent position, at which he was succeeding by all accounts. A few months after this, the two had been living together long enough to decide to get married, which they did soon thereafter.
They continued to live in Karen's house, next door to Claire's, and were joined without advance notice by Jamie's sister Kathy, who knocked on their door one day, apparently down and out. Karen overcame Jamie's objections and told Kathy she could live with them if like Jamie, she conscientiously searched for a good job. Until then she would subject to Karen's supervision, discipline, and monitoring of her intimate functions.
Karen went upstairs to the master bedroom and took off her work clothes and unhooked her bra, which had felt tight. She knew she needed to exercise more and promised herself she would start wearing a Fitbit. She lay down on the bed on her side, leaving her sheer white hicut panties the only clothing she had on.
Soon, Jamie entered and closed the door behind him.
"If I weren't already a panty fetishist," he smilingly told his wife, recalling how she had made him wear her soiled panties while she was supervising him, "staring at your fabulous white undies stretched across that beautiful bottom would make me one," he offered.
Karen turned round to face him and held her arms open, her pleasant-sized 34B breasts aiming right at his glance. Jamie almost fell into her arms, grasping round her torso with his strong arms and holding her tight.
"Is Kathy home yet?" Karen asked, wondering if Jamie's sister, for whom he had little use because his own growing up years had been ruined by the cruelty with which Kathy and his mother had treated him, had secured a job. During her search Karen had agreed to let her live with them, but she was subject to the same control Karen had exercised over Jamie before he obtained his excellent position and later married his dominatrix.
"No," Jamie answered, "maybe she actually landed something."
Soon they heard the front door open and close and Karen rose and put her robe on to see if it was Kathy who had entered. She went downstairs to check and found Kathy in a radiant mood.
"I may be close to having a job," Kathy said gaily. "The interviews went really well and I expect to hear tomorrow or the next day."
"That's wonderful," Karen smiled. "But I want to inspect you now to see if you are taking care of yourself."
Kathy grimaced but responded to Karen's humiliating reference by lifting her suit skirt and yanking down her plain white panties.
Karen gazed down and saw some urine stains in the crotch and worse yet, a long brown streak right across the rear panel.
"You didn't wipe well enough, Kathy, after you both peed and shat," Karen intoned very coldly. "I hope you get this job but I won't have you acting like a spoiled teenager who stains her panties with abandon."
"I'm sorry, Miss Karen," Kathy answered in a plaintive voice. "I know I need to do better but I suppose I was in a hurry when I used the ladies' before my interviews."
Not caring how much she embarrassed Kathy, Karen answered, "You will pay more attention to your wiping, Kathy. I don't care if you cream your undies but I will not have pee stains or poop or reminders of your period when I check your underpants."
Kathy's face reddened and Karen then announced that she would punish Kathy in their bedroom.
"Is my brother home?" Kathy asked with trepidation.
"He is indeed," Karen answered, "and he will see you get smacked on your naughty bottom." She didn't bother adding that Kathy would be further embarrassed by other impositions Karen had in mind for the 30-year-old.
"Can't you punish me in my room or your private room?" Kathy pleaded. "It really is so awful for him to see me get it on my bare bottom and then he sees my lady bits and everything."
