The Story

Amanda was driving to work on Monday morning, having only recently started her new job at an insurance brokerage firm which was her first employer since graduating college. Though she had moved back home with her mom since returning from college, the girl was pleased with her new salary which she felt she could easily save up to get her own apartment, plus she had other benefits like a company car so at 22 years of age, she felt proud of where she was in life.

She was blonde with her hair cut shoulder length, and on the short side with a body that was a teeny bit plump but she felt the softness just made her cute, and at least gave her a bigger butt and thicker thighs to make up for her modest bust. She was dressed smartly for work in a white blouse and a grey pencil skirt, with a matching blazer on the seat beside her.

Amanda was approaching a T-junction when her phone buzzed so she glanced at it to see a message from one of her friends regarding a holiday they were planning. With one eye on the road, she skimmed through the message then began to type a reply, as it was about a special booking offer that her friend thought they could take advantage of if they got on with it, then realised too late that she was pulling out in front of an oncoming car, which had right of way.

The girl quickly accelerated, to get herself clear before the car crashed into her side, while the other driver sharply braked and swerved with the two cars narrowly avoiding a collision. The girl pulled up to the side of the road, her heart racing in panic at the near miss, then rushed out of her car, and with relief saw the other driver had safely pulled up on the other side of the road without crashing, and was also getting out of their vehicle unharmed. It was a woman in her late forties, attractive and just slightly taller than Amanda, with wavy auburn hair, bright red lipstick, and dressed in a turquoise dress that showed the cleavage of her busty chest.

"Are you okay? I'm so sorry!" Amanda apologised, making sure she looked both ways this time before hurrying across the road.

"Yes I'm fine, but not thanks to your driving!" The woman said angrily. "What were you thinking pulling out in front of me like that?"

"I'm really sorry." The girl said again, knowing she was at fault.

"You were on your phone weren't you?"

"What? No, I um..."

"Don't lie! I saw you were on your phone. Was whatever social media you were on more important than the safety of yourself and other drivers?"

"No... I didn't think... I would never do that again!"

"You should be thankful that's the choice you can make, as you certainly wouldn't be doing it again if we had collided and you'd been paralysed or worse... or lost your licence for whatever might of happened to me!"

Amanda looked at her feet, blushing at being told off.

"What's your name?" The woman suddenly asked.

"Amanda." The blonde said, wondering whether she should have perhaps given a false name.

"Amanda sounds a bit too mature for a silly girl like you. I think Mandie is more appropriate."

"Well, Amanda is my name, not Mandie." Amanda snapped, annoyed at being called a 'silly girl' by the angry woman. Sure, she had been caught out dangerous driving, and the woman was rightfully cross, but that didn't mean she could just disrespect her like that.

"Don't backtalk to me Mandie. I should report you for driving like that while using your phone! You nearly caused a serious accident..."

"Look, I said I was sorry. Could we just forgot it please? No harm done and I promise I've learnt my lesson!" Amanda said, bristling that the woman was insisting on calling her 'Mandie' though thought it was best not to argue with her about it if she wanted to get away without being reported.

"I don't know... I bet if I let you drive off you'd just be back on your phone in a heartbeat, and won't learn until you've had a serious accident or been in serious trouble. And I think trouble is much preferable to an accident, don't you Mandie?"

"I promise I've learnt my lesson. It was the only time I've used my phone at the wheel and I won't ever do it again!" Amanda pleaded with the woman, who wasn't seeming convinced. "Look, how about I pay you a little for all the trouble I've caused..."

"Oh, so as well as a silly girl, you are some spoilt brat who thinks she can pay her way out of trouble. Oh no, you definitely need to be reported as think you'll take the police more seriously than you are me..."

"No please, it's not that I'm spoiled... I just wanted to make it up to you without getting the police involved. Please, it's a company car so any incidents involving the police will go back to my employer, and it's my first ever job and I'm still new so it could get me fired!" Amanda appealed to the woman, aware that admitting it was a company car could backfire but hoping it showed the lady that she was taking this seriously and didn't need the police involved.

"Work car huh? Yes, I imagine if your employer found out you could get in quite a bit of trouble Mandie!" The woman said, seeming to be pondering something which Amanda hoped was forgiveness. "How about we strike a little deal? Instead of reporting you to the police, you shall come back to my house so I can punish you personally in a way befitting a silly brat, sounds fair? That way you learn your lesson without the police or your employers ever knowing..."

"Punish me? What do you mean?" Amanda asked, shocked at the strangeness of the suggestion. She couldn't imagine what the woman could possibly have in mind.

"It won't be anything much, just something to make you remember this lesson next time you find yourself reaching for your phone while driving. But you'll have to agree to go through with it!"

"How can I agree if I don't know what it is?" Amanda said.

"Okay Mandie, the police it is then..." The woman said, reaching into her handbag for her phone.

"Okay fine, I'll do whatever you want me to, just please don't call the police." Amanda agreed desperately. Surely whatever it was wouldn't compare to the threat of her losing her job, so she resolved she'd just have to go through with it. 'It's probably something dumb like writing lines... maybe she is a teacher.' She thought to herself.

Leaving her car on the side of the road, Amanda fetched her handbag from the passenger's seat, then reluctantly climbed into the woman's car, hoping she wasn't making a serious mistake.

"Who are you texting?" The woman asked, seeing Amanda had pulled out her mobile.

"Oh, I was just telling work I'd be a little late in..."

"You better tell them you shan't be in today at all... just say you're sick or something."

"Really, this is going to take all day?"

"Yes, though perhaps the police would be quicker?"

Amanda sighed, but begrudgingly texted her boss to say she had an awful migraine so wouldn't be in office today.

****

Amanda sat in sullen silence in the passenger seat, wondering what the woman could possibly have in mind as her punishment. They didn't speak as they drove back to her home in the wealthy suburbs, turning into a cul-de-sac road named Sapphire Lane where they pulled into the driveway of house No. 26. It was a large detached house, and Amanda found herself even more cowed as it was clear the woman was quite well-off.

"Oh, I haven't even introduced myself, my name is Isla..." The woman said as they got out the car. "... but you will call me mommy today."

"Mommy?" Amanda said, frozen in shock at the demand.

"Yes Mandie, not hard is it?" Isla grinned then led the way to the house. Amanda reluctantly followed, unable to believe the woman wanted her to call her 'mommy' with it suddenly dawning on her that this mysterious punishment she had agreed to could be sex related.

"Why should I call your mommy? Are you a lesbian or something with a kink for younger woman!"

"You should call me mommy as otherwise you'll me calling me ma'am in front of the police. I hope you don't answer back to every simple little instruction or otherwise I shall have to make your punishment much worse... so is it mommy or ma'am?"

Amanda frowned but sighed "Mommy."

"Good girl!" Isla smiled, pinching her belittlingly on the cheek, before unlocking the front door and letting them inside. The woman's house was as nice inside as it was outside, and she followed the woman in the large airy lounge with plush sofas, a large TV, and a well-stocked bookcase.

"First we'll start with a spanking, strip out of those clothes Mandie." Isla said, sitting on the sofa.

"What!" Amanda exclaimed, shocked at what the woman was proposing though thought she probably should of guessed it would be something weird and demeaning like that as soon as the woman had proposed to punish her in a way 'befitting a silly brat'.

"Are you a brat who answers back, or just a little dim-witted when it comes to understanding commands? Take off your clothes and bend over my knee."

"If you're going to spank me, couldn't we just do it with my skirt on?" Amanda said, not believing she was actually negotiating a spanking with the woman.

"No, besides I think those office clothes are far too mature for a silly girl like you. Now hurry up!"

Amanda sighed, but decided arguing with the woman might just make matters worse, so placed her handbag on the sofa, and reached behind herself to unzip her pencil skirt. 'The quicker I get this over with, the faster I can get out of here though not sure why she told me to tell work I wouldn't be making it in today if it's just a spanking...'

She pulled down her skirt then removed her blouse so she was stood in her black lace underwear, then hesitantly went over to the woman to bend over her knee as instructed.

"Take off those bra and panties too."

Amanda grimaced but stripped naked in front of the woman, thinking how she had never been nude in front of a stranger before. She wasn't ashamed of her body but felt humiliated to have it on display to the attractive authoritative older woman, and she shivered slightly, not because it was particularly cold but because it felt weird to feel the light breeze from an open window all over her naked skin.

"Gosh, maybe you are a little dim-witted. I told you to come bend over my knee, not just to stand there." Isla said, and Amanda blushed at being scolded by the clothed woman. She, though mortified at the position she was putting herself in, bent over the woman's knee so her big ass was ready for the palm of Isla's hand.

"What a cute butt. So soft..." Isla said, caressing her fingers over it. "Is it used to being spanked?"

Amanda shook her head, not remembering ever having been spanked in her entire life.

"Surprising, as if I was your mother I would definitely be using it as a regular method of discipline. Perhaps with some spankings, you would have been a less reckless driver and not be in this predicament right now." Isla said then slapped her hand down on the girl's bare bottom. Amanda squealed, though mostly from surprise, as the woman followed the slap with three spanks, in quick succession, on her right buttock, before administering the same number to her left. Each slap was loud, and made Amanda's butt jiggle, with the blonde moaning in humiliation and twinges of pain though she was ashamed to admit that the sensation was weirdly pleasurable.

'I might even enjoy it if it was during some kinky sex, and not as punishment from a stranger!' Amanda thought though as the spanking continued and her butt reddened with soreness, each slap slowly became more stinging. Isla was alternating buttocks with every fifth or sixth slap, which gave each ass cheek a longer break, but meant when it was receiving attention, it had to endure more at once.

"Tell me what this is teaching you." Isla said, not pausing in spanking the girl.

"That I shouldn't use my phone while driving... Ow! I promise I will never do that again and make sure I'm much more careful on the road!" Amanda simpered, crying out a little when a slap was particularly stinging on her sore ass.

"Good girl. Now thank me for taking my time in teaching you a lesson rather than just letting the police deal with you."

"Thank you mommy, thank you for teaching me to be good!" Amanda cried, ashamed to be pathetically thanking somebody giving her a bare bottom spanking at 22 years old.

"Okay, I think that's enough... Your butt is even more adorable when it's a shade of reddish-pink!" Isla grinned, letting the naked girl stand back up. "I'll just go and get a few other bits for the next part of your punishment."

Amanda was left waiting, standing by the sofa and caressing her sore butt which she couldn't believe she had allowed to be spanked, but despite how embarrassing it was, she admitted it was better than having to explain her driving to the police and risk losing her job because of it. She wondered what the woman was fetching, and guessed her punishment wasn't over yet... 'maybe she's going to make me clean her house or something...'

Isla returned, placing a bunch of things on the coffee table which Amanda looked at in disbelief. It was a bottle of talcum powder, a light blue bodysuit with a pattern of cartoon daisies, some oversized mittens, and, what drew Amanda's gaze the most, a white adult diaper with a pattern of blue stars.

"What is all of this for!" She exclaimed.

"For you to wear silly." Isla said, unrolling a changing matt, patterned with cartoon jungle animals, on the carpet.

"But that is a diaper!"

"Yes, you aren't as dumb as I thought." Isla laughed sarcastically. "Now lie down on the matt."

"No way am I wearing that!"

"Yes you are, this is part of the punishment we agreed on for me to not call the police. Or would you prefer if I spoke to your employer directly about you nearly crashing the company car they unwisely gave a silly little brat like you?"

Amanda groaned, but moodily sat on the matt, thinking how the spanking seemed relatively dignified when it was compared to being diapered. The blonde led on her back and reluctantly lifted her butt off the ground so the woman could slide the unfurled diaper beneath her. She lowered her butt back down on the adult diaper, thinking it actually felt kinda nice on her sore buttocks, but the humiliation of what was happening to her quickly drove that thought out of her mind.

Isla reached for the bottle of talcum powder, and sprinkled it over the blonde's clean shaven pussy. 'Is she actually thinking I'm going to wet myself in this diaper, or is the powder to just make it feel even more mortifying...' The woman closed the diaper and taped it up on the girl who couldn't believe, as a 22 year old insurance broker, that she was actually wearing a diaper.

"Do you like it?"

"No!" Amanda moaned.

"Oh come now, it's cute and definitely suits you! Or I can get you another diaper, I have ones with more girly patterns or ones that are bigger and bulkier..."

"No, I'll stay in this one." Amanda sighed, not wanting to make her punishment even more embarrassing than it had to be.

"Good girl, so you do like it!"

"Yes..." Amanda was forced to say, though she definitely did not like the diaper.

"Tell me properly, I think you can manage sentences rather than just single words. And remember what I told you to call me Mandie!"

"I like this diaper mommy." Amanda blushed, the words feeling surreal as they came out her mouth. She was mortified at being made to say it but then reasoned she hadn't any more dignity to lose seeing she was lying diapered on a changing matt, smelling of talcum powder.

Isla laughed then ordered the girl to stand up and put her arms up so she could pull the bodysuit onsie onto her. It had short sleeves but no legs, and a snap crotch which the woman pulled down over the girl's diaper then clipped closed. Though the onsie hid her diaper, it did nothing to obscure the shape so the blonde knew that anyone looking would be able to tell straight away she was diapered beneath it.

"Why do you even have diapers and this onsie thing..." Amanda asked as the woman tugged her onsie a little so it was neatly in place.

"That's a fair question. It's bad luck for you that our near miss happened when it did as I only recently got all of this stuff. You see my 18 year old goddaughter is a naughty brat like you, and she's coming to stay with me for a few weeks when her mother's abroad on a business trip, so all of this is to surprise her! She is going to be diapered just like you, and dressed in silly little rompers, pyjamas, dresses, and other cutesy things only for her it will last for weeks until her mother returns, while you should be thankful I'll be letting you go later today..."

Amanda found it hard to be thankful as she'd rather not be diapered and spanked at all, even if it was only for a day but was certainly glad she didn't have a godmother like Isla. She wondered how the woman expected her goddaughter to go along with it all, especially for weeks, and pondered if the woman had some blackmail material on that girl too.

Meanwhile Isla had picked up mittens from the coffee table, and made the blonde hold out her hands so she could pull them on. They were bondage mittens that tightened around her wrists so she wouldn't be able to remove them without the woman's help again, but made of thick pink material, that was soft but prevented her from using her fingers, rather than black leather that ones in BDSM would normally be made of.

"This way I won't have you touching things I don't want you to. If only you could wear them driving as that'll stop you using your phone, though suppose they'll get in the way of driving the car too." Isla laughed.

Amanda felt more vulnerable now she was in the bondage mittens, as before she was just constrained by the threats of the police, but now she was also physically limited with what she could use her hands for. 'Was making a deal with this crazy woman the best idea? What could she want to do to me next!'

Isla told the blonde to follow her again, and they left the lounge, with Amanda glancing at her handbag being left behind on the sofa which contained her car keys, phone, and purse. Not that she would be able to handle any of those object with her hands in the mittens...

At the end of the corridor was a wooden bench against the wall, and the girl saw that on the legs of the bench were two chains which ended in fluffy pink ankle cuffs. Above the bench, on the wall, was a hook which dangled two more chains which ended in fluffy pink wrist cuffs. It wasn't hard for Amanda, slightly panicked, to guess what the fours cuffs were for...

"This is the 'naughty step' I created for my goddaughter, though you shall be the guinea pig testing it! Hop on."

"You aren't going to cuff me are you mommy? I promise I'll sit here for as long as you want without them..." Amanda said, wanting to avoid being made even more helpless in the weird woman's house, and hoping that willingly addressing her as mommy would help persuade Isla to be more lenient towards her.

"You always have questions or complaints to every instruction I give you Mandie. Come on, hop on the naughty step otherwise I'll sit there instead to give you another spanking over my knee."

Amanda climbed onto the bench, and sighed as the woman bent down to bind her ankles in the comfortable, but secure, fluffy cuffs. Isla then pulled the blonde's arms above her head to cuff them to the hook on the wall. The girl wiggled on the bench, finding the wood wasn't uncomfortable with the cushioning of her diaper, but not liking how she was now utterly helpless. It seemed the woman was just taking advantage of her to explore her weird fetishes, however Amanda couldn't help thinking of the dangers of allowing herself to be tied up by a stranger, especially when no one knew she was even there.
