Deirdre Carmody took the speed up on the Honda NSX sports car she was driving down to her niece Laura's weekend school. Deirdre had more or less brought Laura up and she was looking forward to seeing her after several years. And that Laura, who had her own inheritance so could do more or less what she wanted, had invited her made her that much more pleased with the prospect of reuniting with her clever niece.
She had dressed nicely in a somewhat "country" style: tweed skirt, nice chenille blouse, flats, and sheer hose. Deirdre was in her late 40s but retained a pleasant figure and a lovely face. She had been married but lost her husband in a freak accident. So raising her niece Laura when Laura's parents divorced and re-located was a renewal of life for her.
Arriving at the school, Deirdre was impressed with how well-appointed it was. Everything made her recall her own days at a premier girls' school and she also began remembering the way the mistresses punished the girls, with tawse and cane. No sooner had she rung the bell and walked into the nicely-furnished entry hall but Laura emerged, dressed somewhat severely, as if she indeed were a school mistress, to greet her.
"Aunt Dede," she gushed, "what a pleasure!"
Deirdre hugged her niece whose appearance impressed her. Laura really did look the part of the Headmistress as the niece explained to Deirdre how the place functioned. Deirdre grinned when Laura told her how she played the role of a prefect, but at the assembly the final morning, the pupils returning to experience their former life were surprised to learn she was actually the Head.
"And yes, Aunt Dede, we do punish them somewhat severely," she added, as she related the proceedings of that morning's assembly, detailing the various canings and humiliations to which the students were subjected. She led Deirdre to a comfortable room with a large bed and plenty of closet and drawer space.
"I'd like you to meet my colleagues if you don't mind," Laura said. "Melody is older and was once my teacher, Anne is my age and has a nice strong personality, and Diana is just 20 but is quite attractive and has learned to be severe as needed," she explained. "I haven't ever let any of them discipline me, however, and I hope you might be willing to do that when we are with them. It would do them good to see that I can take it. And maybe, my dear Aunt Dede, you might wish to bare your bottom..."
Deirdre blushed and began to feel herself get wet down in her knickers.
"Oh, Laura," she said excitedly, "you do remember the way I used to punish you. It really was for your own good, but yes, a bit for me, too," she confessed. "I'll be willing to let you put me through my paces if you feel that would even things up. And yes, I feel we both enjoy some of this, or maybe more than some, don't we?"
Laura hugged her aunt and said, "Let's start her for a moment. Aunt Dee, please lift that skirt for me."
Shamefacedly, Deirdre lifted her tweed skirt, exposing her rather pretty pale blue knickers she had only recently selected on a trip to Harvey Nichols.
"We have some nice lingerie, I see, my dear," Laura said with a wicked grin. She proceeded to insert her thumbs in the waistband of her aunt's gorgeous underpants and slowly pulled them down to her knees.
"Hmm, I see we still don't shave but I'm pleased you do trim that forest a tad," Laura commented. "Now over my lap, sweetie."
Deirdre, embarrassed to the core by now, complied with her niece's order and felt silly lying across Laura's skirted lap. Her embarrassment was swiftly interrupted by Laura's strong arm applying spanks to Deirdre's bare, white bottom. The spanks hurt but Deirdre felt herself getting very, very, excited and wet down between her legs.
Laura rather commandingly ran her finger between her aunt's spread legs and noted, "Hmm, this girl appears to be quite wet as she is being disciplined. I shall have to make an entry on her term report under Conduct."
"Oh, please, Miss," Deirdre responded, falling into character, "please don't mark me down in Conduct for that! My mother will whale my poor bottom all over again if I bring home a bad mark in Conduct!"
"You should have thought of that before my prefect caught you with your finger down there being naughty," Laura replied with some dripping sarcasm. Then the now-experienced disciplinarian slowly inserted her finger into Deirdre's cute little recessed bottom-hole as Laura's aunt began to breathe more heavily in response to this extreme stimulation.
"Oh dear," Deirdre whimpered, "I'm sorry, Laura dear, but when I get ... stimulated like that it makes me need to, you know, go....and I'm afraid I may...have an accident now. Can I go to the little girls' room?"
Smiling, Laura said coolly, "I'm so sorry, Aunt Dede, but you know that naughty girls cannot be excused during their disciplining. You'll have to hold it...or else subject yourself to very serious punishment."
"Laura!" Deirdre now whined loudly, "Laura, I'm going to make a doody right here if you don't let me..." Laura responded by reaching down and pulling Deirdre's knickers right up snugly around her bottom.
"Oh, Laura," Deirdre almost screamed, "I'm losing control, oh no, I'm making one right in my knickers! Oh, this so embarrassing!!"
Laura well remembered when she had been disciplined like this by her aunt. In fact, when she was 17, she had not been allowed to use the toilet and filled her knickers while Deirdre was spanking her. She revelled quietly now in her aunt's discomfiture.
"Oh, Aunt Dede, you are so naughty!" Laura exclaimed. "You've filled your knickers with soft brown poopoo!"
"I know, Laura, I know!" Deirdre cried. "I made a doody in my undies! At my age, how shameful!"
"We'll clean you up and take care of this little situation," Laura said as she briskly pulled down Deirdre's knickers and got them off her legs without spilling the soft shit in the crotch. She quickly deposited them in a canister in her personal bathroom for cleaning later. Then she took a sponge and washed off Deirdre's shit-smeared buttocks and crotch with a clean cloth.
