Yvonne was feeling a great deal more confident now that she had definitively brought her 24-year-old stepdaughter Kathryn under her control. Kathryn had been defiant but had gradually been made to play by Yvonne's rules once it became clear that her daddy, Yvonne's husband Dennis, was not going to interfere with the rule of the house exercised by his very attractive 26-year-old wife.
For a few weeks after Kathryn received her ignominious spanking on her bare bottom in front of her boyfriend, no less, the atmosphere in the home had been tense but calm. Kathryn again misconstrued Yvonne's allowing her to live without much interference as a sign of non-interest or even weakness. So after three weeks, Yvonne called her stepdaughter into her bedroom. Being in the bedroom where Kathryn often could hear Yvonne fucking her father made the lithe blonde Kathryn nervous. Yvonne preyed on that feeling once she observed Kathryn's unease.
"We have not reviewed your behavior for a few weeks, Kathryn," Yvonne began, taking the offensive as always.
"Oh, Yvonne," Kathryn replied, without thinking, "can't we dispense with this? I've shown you that you are in charge, haven't I?"
"Kathryn," Yvonne answered, slowly, "as long as you live in this house, you will be subject to our rules. I have indeed felt your behavior has improved, but there remain matters to be discussed, and if necessary, acted upon."
Kathryn grew nervous at hearing that last phrase, as she expected it would mean her bottom would be a target again for Yvonne's hand or, worse yet, the thin cane she kept in her handbag.
"I think you will benefit from a panty inspection now," Yvonne announced, "so please lift your skirt and lower your panties now for me."
Kathryn resented the humiliating order but had come far enough to realize the nasty consequences of failure to comply with Yvonne's humiliating instructions. So she did as she was told and the young stepmother peered into the crotch of Kathryn's stylish purple hicut panties.
"As I said, Kathryn," Yvonne observed, "your behavior has improved but I'm sorry to say that there are stains in these panties. I have a feeling you have been engaged in some self-arousal, unless I'm very much mistaken."
Kathryn cringed and her face reddened with shame. How could this woman so easily see through her? Wasn't it enough that she had to lower herself so in front of others?
"Yes, Yvonne," Kathryn responded in a small voice. "I'm sorry but I couldn't help getting some relief since you told me I couldn't go out on a date during the week until my room was spotless."
Yvonne smiled and said, "But you also know that I made it quite clear that you were not to engage in this kind of thing and certainly not to stain your panties as a tell-tale sign." Kathryn now was frightened because she knew this young woman had a core of steel and would stop at nothing to exercise her will and crush Kathryn's until-now indomitable spirit.
"Mother," Kathryn said, using the title Yvonne required during punishment sessions, "I'm sorry for misbehaving and would appreciate your immediate correction so that I learn from my errors and do not repeat them."
Yvonne smiled. This girl was coming along quite nicely and was learning to be a good little sub.
"Very well, Kathryn," she said firmly. "Since you have confessed and requested punishment, I will oblige you. Keep your skirt well above your waist and your panties down and get across my lap," she directed, patting her lap quite noticeably.
Kathryn felt like a small child when she crawled across her stepmother's narrow lap. But soon she began to cry and squeal and ask Yvonne to stop when the spanks began on her bare bottom cheeks. After completing a reasonable spanking, Yvonne told Kathryn to get up and lie across the bed on her tummy.
This was when Kathryn was most afraid. She knew Yvonne would be retrieving her little thin cane from her handbag, where the young stepmother kept it handy for immediate use at all times.
Yvonne now stood behind her, having reached into the handbag for the cane and withdrawn it and placed it across Kathryn's broad bottom cheeks.
Soon Kathryn felt the cane drawn back and with a flick of Yvonne's svelte wrist, the rod snapped across her step-daughter's bottom and soon left two tramlines emerging in red as Kathryn cried out in pain. Yvonne then flicked the little cane twice quickly, administering two more strokes to a surprised Kathryn, who reacted more or less involuntarily to the surprising extra stroke by releasing just a tiny jet of pee from between her legs.
But the ever-vigilant Yvonne saw the girl's tiny peehole open for the instant.
"Kathryn, you have allowed yourself to release urine on my bed," Yvonne announced.
"I couldn't help it, Mother!" the girl cried. "I think that last stroke coming so fast made it so I couldn't ....couldn't keep for letting a tiny bit of pee out." It clearly humiliated her to have to explain to this young stepmother why a woman of her 24 years had lost bladder control, if only for an instant.
"Well," said Yvonne with some gravity, "I do think we shall have to correct this behavior of yours before it gets out of control altogether." With that fearful comment, she went into the closet and returned with an adult-sized diaper that she told Kathryn to move into diaper position on the bed so she could be placed inside it.
"Oh no, Mother, please not a diaper," Kathryn pleaded. "I'll be humiliated before everyone!"
"You will only need to be discreet about your dress," Yvonne answered, as she readied the shameful diaper to be placed between Kathryn's legs.
First, she told Kathryn she would powder her so there would be no diaper rash, as Kathryn winced at the reference to the babyish problem to which Yvonne lightly referred.
She sprinkled the talc between Kathryn's legs and rubbed it all over her mons and labia and down to her little anal rosebud. Kathryn began to respond to the stimulation. Now Yvonne started to tease Kathryn's rising little clit which became a large button as Yvonne just let her fingertips graze the very tip.
Kathryn began to buck and could not keep for orgasming and thus releasing some juice into the diaper.
"You will wear the diaper with your cum in it," Yvonne said with a slight note of disdain. "And if you need to make a doody, you will come and ask me to release you so I don't have to change a poo-filled diaper."
Kathryn hated it when Yvonne used the d-word to refer to her feces. It made her feel like a small child, which was exactly what her stepmother intended.
Now Yvonne pulled the diaper tight and taped the tapes. She brought out the final insult—a pair of plastic panties for Kathryn to wear on top of the ignominious diaper.
Kathryn knew better than to protest and merely began to think of how she could keep from making a crinkling noise when she walked so that everyone would know she had a diaper and plastic panties on.
Yvonne tapped her on the crotch of the diaper which meant she could get up and let her skirt down. She had moved her tactics of humiliation quite a bit ahead with respect to Kathryn, she decided.

Dennis returned home with a funny feeling. He walked into the house and saw Kathryn in the kitchen, looking glum.
