S L The Goddaughter Pt 01

Author's note: This series involves a diaper fetish, including wetting, messing, humiliation, mommy domination, and other related kinks. Please don't read if these themes do not appeal to you.

This is part of the 'Sapphire Lane' universe, and follows on from the story 'The Dangerous Driver' which serves as a sort of prequel. Not an essential read but one you'd probably like if you enjoy this series.

Chapter 1

"Tell Isla I'm sorry I can't drop in for a bit, as I really need to rush to make the flight. Have a nice stay!" Anastasia's mom told her before driving off, leaving the girl stood at the entrance of Sapphire Lane with her roller luggage.

Anastasia shrugged, and walked down Sapphire Lane, a cul-de-sac in the suburbs lined with large detached houses. She was a pale girl, with straight dark brown hair, icy blue eyes, and round face that was cute rather than beautiful, and highly expressive with eyes that easily widened, and a brow that often furrowed.

She was fairly short, slim but not skinny with a cute butt clad in ripped denim shorts, and teardrop shaped breasts that had a gap of pale chest between them, and though a little fleshy, were fairly flat so didn't cause much of a visible curve beneath her green vest.

The girl followed the bend in the road until she got to No. 26 which was the home of Isla, her godmother who she had been sent to stay with for a fortnight while her mom was abroad on a business trip. At eighteen years old, Anastasia was perfectly capable of staying at home by herself however her mom knew from experience that her daughter would throw house parties in her absence so this time had insisted she stayed with Isla instead.

The girl had argued, reminding her mom of a burglary that had happened to them not too long ago where the woman had lost all her jewellery, so suggesting it would be best if they didn't leave their house empty. However her mom had rejected this excuse, saying that it wasn't like her jewellery could be stolen for a second time!

Reluctantly the girl knocked on the door. She hadn't any specific dislike for her godmother, but was embarrassed to be forced to stay with her while her mom went abroad, and knew the woman would be quite strict towards her even though she was an adult.

Isla answered the door. She was in her late forties, attractive and around the same height as Anastasia, with wavy auburn hair, bright red lipstick, and a busty chest which she often seemed to show off with her chosen outfits. Today she was dressed casually in jeans and a white vest that displayed her cleavage which even her goddaughter couldn't help glancing at appreciatively.

"Hi honey, how are you?" The woman greeted her goddaughter, pulling the girl into a hug. Anastasia blushed when she felt the woman's breasts push against her chest.

"I'm okay, mom was running late as usual so she had to rush on to the airport rather than popping in..."

"That's okay, we don't want her to miss her flight. Come in, you can leave your luggage in the hallway for now." Isla beckoned the girl inside and led her into the spacious lounge with plush sofas, a large TV, and a full-to-the-brim bookcase.

Anastasia sat on one of the sofas, and it wasn't long until her godmother joined her, with coffee and biscuits.

"So, how are things going academically?"

Anastasia sipped her coffee, blushing as she knew her godmother would be asking her about that. She had flunked her high school exams quite badly, which meant her mom had refused to pay for an end of school holiday. She had managed to go on it anyway, but now, when all her peers had gone to college, gotten apprenticeships, or even just went straight into work, she was studying from home to do some retakes which hopefully meant, after a 'gap year', she could begin at Violet Liberal Arts College who had rejected her based on her current grades.

The girl had meant to have gotten a part-time job too, her mom insisting she contributed to living costs while also at least getting a little work experience in her gap year, but so far Anastasia had been too lazy to get round to it.

She told her godmother a vague outline of this, trying to make it sound like it was more due to bad luck than laziness on her part when it came for studying, however knew the woman likely had heard everything from her mom anyway.

"So how did you pay for the holiday if your mom refused? As you never had a job, and it seemed quite a lavish one from the photos I've seen online for you to have paid for by saving up your allowance!"

"Oh, I won a lottery ticket that about covered it. Guess I'm lucky some of the time!" Anastasia forced a laugh, though in truth how she had paid for her holiday was an awkward subject.

"Really, because I thought that was what all the money from your little scheme would have been spent on..." Isla smiled knowingly at her goddaughter.

"My little scheme?" Anastasia asked, her eyes widening at the question though tried to remain composed, telling herself it must be some joke she just wasn't getting.

"Okay, let's not beat around the bush, I know you stole your mom's jewellery then offloaded it to pay for the holiday!"

Anastasia's hand shook, and she had to put her coffee down. "What the hell? Why would you think that? It was burglars!" She tried to act both shocked and angry at the accusation, but gave a poor performance, as she was really reeling at how her godmother had known!

Isla rolled her eyes. "Don't try pretending honey, I've got the jewellery upstairs. I happened to go into that weird little thrift store that does jewellery after hearing about how your mom's was stolen... I was just looking for a trinket for a fancy dress costume so was shocked to see a box of rings, necklaces, brooches, and earrings which I recognised as belonging to your mom! So of course I bought it all..."

"So you found her jewellery! Why haven't you told her then? And what's that got to do with me, the burglars must of flogged it to the store!"

Isla laughed. "Because I also asked the store owner who brought it in, saying I recognised it from a friend and they said it was some young woman matching your description... and then confirmed it was you when I showed them photos from your social media. I then explained the situation a bit more, and persuaded them to find the CCTV footage of you as evidence..."

Anastasia flushed, knowing she couldn't pretend now. "Okay, it was me... I just really wanted to go on the holiday and my mom was refusing to pay for it!"

"So you stole all her jewellery? The value is one thing, and it was quite a large sum you took, but didn't you also think how irreplaceable some of it was, like I know there were items passed down from your grandmother, and great grandmother!"

"Yeah... my mom was really upset and I felt bad. I even went back to the store but they didn't have it there so guess that was after you found it... so thought I might as well go on the holiday. But why didn't you tell my mom all this?" Anastasia wondered, not thinking her godmother was the type to protect her from trouble she most definitely deserved.

"Because I want to make a little deal with you... as I can either anonymously send the jewellery box back to your mom when she's back from her trip, or go to her with it and the CCTV footage, and explain exactly what you did."

Anastasia imagined how furious her mom would be, and knew she didn't want the woman to learn the truth of what happened to her jewellery... perhaps she'd even kick her out the house! Truth was she really had felt bad about it, knowing she had behaved unforgivably selfishly towards her mom.

"Please just send it back anonymously. I am really sorry, and definitely have learnt my lesson..." The girl begged her godmother. "I could try pay you back..."

The woman snorted. "I think it'll be a long time until you can pay back the money! No, that wasn't the deal I had in mind..."

"Then what?"

"If you agree to do anything I tell you during your stay here, then I'll return the jewellery anonymously."

"Anything you tell me? Like cooking and chores and stuff..." Anastasia asked, confused.

"No quite those things. You'll see... so is that a deal?"

"Okay sure." The girl reluctantly agreed, not knowing what she was getting herself into but she needed to prevent her mom from knowing the truth at any cost. It was just a fortnight so how bad could it be? Anastasia couldn't help wondering if it might be sex related, as she knew her godmother was a lesbian, and found she didn't mind the idea too much... sure it was weird, as the woman was her mom's best friend and had known her all her life, but the older woman was attractive and though the girl didn't appreciate being blackmailed into it, sleeping with her wouldn't be so bad...

"Good, that's the choice best for both of us! Now, while you stay here you shall call me mommy."

"Call you what?" Anastasia exclaimed, her eyes widening. Perhaps her taboo thought about it being sex related was right, but she hadn't been expecting something kinky like that.

"Mommy, and also don't answer me back. The deal was to do what I said wasn't it, not to argue."

"Yes..."

"Yes what?"

"Yes mommy." Anastasia blushed. She wouldn't even call her own mom that let alone someone else, but she guessed she had no choice to play along with whatever weird game her godmother had devised.

"Good girl, but I can see you'll be bratty so think we'll begin your stay with a demonstration of what will happen if you misbehave... over my lap, now!"

"Over your lap?" Anastasia gaped.

"Honey, are you a girl or a parrot? Lie over my lap now!"

Anastasia hesitantly obeyed, realising in shock that she was probably going to be spanked by her godmother, not being able to come up with any other conclusion to what she could be doing in this position. She shivered a little as she indeed felt the woman's hand caress over her butt, and even though she had guessed what was going to happen, she still cried out in surprise when the woman slapped her buttock. It didn't particularly hurt, after all her skin was covered by her panties and denim shorts, but being spanked, at eighteen years old, was humiliating. Not even her mom had ever spanked her!

Isla's first slap was followed by more, alternating between the girl's butt cheeks then pausing to grab her goddaughter's wrist in her free hand, twisting it behind her back and holding it there so she would stop wiggling. The girl couldn't believe she was being womanhandled like a little brat, and almost fought back to break free of the grip so she could escape the continuing humiliation of being spanked by her godmother, but then remembered their deal and the consequences if she broke it... Being spanked was embarrassing, but her mom learning she had stolen all her jewellery was a prospect far more awful.

"That's just a warm up, now let's get these shorts off... and panties too unless you're too skanky to be wearing any." Isla said, and letting the girl stand back up briefly so she could unzip the front of her denim shorts and roughly tug them down, along with the blue panties the girl was wearing, which she made the shocked girl step out of, discarding them on the sofa next to her.

"Wha..." Anastasia tried to protest, shocked to find herself naked from the waist down with her pretty pink pussy exposed, as well as her little bush of brown pubic hair, however before she could formulate any response, found herself pulled back over the woman's lap. The spanking continued, now on her bare butt, with the slaps a little more stinging now she was without the protection of her panties and denim shorts.

The girl's pale butt cheeks quickly turned pinkish-red from her godmother's spanking. Isla enjoyed the ease in which they changed colour, and thought how pretty the red marks looked in contrast to the pale skin. The girl's butt wasn't as softly plump and jiggly as Amanda's, a young woman who Isla had caught dangerous driving and taken the opportunity to use as a sort of test run, but it was still cute and pleasurable to slap.

The woman had been alternating between the buttocks, but varied it a little with a flurry of successive slaps to one butt cheek which made the surprised teen squeal before the woman's disciplining palm moved to her other buttock to give it the same firm treatment.

Anastasia couldn't pretend the spanking was extremely painful, however it was beginning to smart, and she felt sore spots across her butt, that when smacked by Isla's hand, were beginning to sting however it was all made worst by the humiliation of being treated like this at eighteen years old, with nothing she could do but take the demeaning punishment.

"Your mother should have done this to you a long time ago! With a little more discipline, you might not have become such a lazy academic failure and selfish brat that you'd steal your own mother's jewellery for the sake of a holiday... tell me I'm right."

"You're right." Anastasia said begrudgingly, moaning a little as the spanking continued.

"Tell me what I'm right about."

"You're right, my mom should have spanked me then maybe I wouldn't have been a lazy failure at high school, and a selfish bratty thief..." The teen said, blushing as it felt like there was a ring of truth to the words, and then whimpering at a particularly stinging spank that made an especially loud smacking noise.

"Yes, oh well, better late than never! Thank me for giving you a spanking."

"Thank you." Anastasia said, hoping that Isla was going to stop, as though earlier it seemed more embarrassing than painful, her sore butt was now really becoming quite sensitive to each slap.

"I think you're forgetting what you're meant to call me." Isla said, giving the girl an nasty smack on each butt cheek, then a flurry of quick ones on the back of her exposed pale thighs too.

"Ow! Stop..." Anastasia begged. "Oh, thank you mommy!"

"Good girl. Now, when you are in this house, any time you misbehave, you'll get a spanking like this... is that understood?" Isla said, and the girl nodded. A final little slap made the teen voice her agreement with a submissive "Yes mommy."

"Now go and stand in the corner, facing the wall." Isla said, helping the girl back to her feet.

"The corner?"

"Yes, while I fetch your new outfit."

"My new outfit?" Anastasia asked, confused and concerned.

"Really Anastasia, I already told you not to be a parrot repeating everything I say! Yes, your new outfit, as I shall be dressing you while you stay with me! Now to give me a break from you echoing everything I say, open your mouth."

Anastasia blushed at the scolding, wondering what her godmother was planning to make her wear... thinking perhaps if things were sexual, she'd be put in slutty outfits. Nevertheless she opened her mouth, with her eyes widening when she found her blue panties stuffed into it.

"There, now the corner."

Anastasia mumbled through her pantie gag, her 'Eww!" at the grossness of having her worn underwear shoved between her lips muffled, and reluctantly turned to go into the corner, facing the wall like a naughty school girl, not that they punished students like that anymore... She tried not to notice the flavour of the panties on her tongue, but couldn't help tasting a hint of sweat and also a tinge of musk from her pussy. Meanwhile her ass stung from the spanking, and she blushed how her position meant she was displaying her rosy butt cheeks even though it was only her godmother in the room... Perhaps in some other circumstances, like roleplay with a girlfriend, something kinky like this might turn her on, but she just felt shock and embarrassment as well as concern with what the woman's plans were for her.

Isla picked up the girl's denim shorts, and also her mobile phone she had left on the coffee table, and left the lounge, glancing at the brunette in the corner with a smirk, again pleased to see how red her butt was from the spanking.

She turned off the girl's phone, and put it alongside her denim shorts into the roller luggage, then pushed the case into the closet under the stairs which she locked, as her goddaughter wouldn't be needing any of her clothes, toiletries, purse, phone, and makeup during her stay.

The woman then went upstairs to the bedroom she had prepared especially for her goddaughter's stay. It was decorated girlishly in bright pink with shelves full of soft toys, and a bed surrounded by wooden barred walls, with one side pulled down currently however when raised would transform it into a big crib.

In one corner was a princess tent, and in the other was the closet full of cute dresses, and a chest of drawers full of other girlish clothes. There was also a small bookshelf however it wasn't books stacked on it, but packages of various kinds of adult diapers.

She was very pleased with the room, having been quite a bit of work and expense to put together, especially in a relatively short time on discovering her friend's stolen jewellery in order to blackmail her goddaughter with. She felt sure the girl would cave into the blackmail but if it hadn't worked, she'd at least have the room ready for another opportunity, and there was always Amanda, the dangerous driver she had used to try some things out on, who she was sure she could always call back under threat of leaking some embarrassing photos she had taken of the blonde.

Isla picked out an outfit and diaper, and also a bottle of talcum powder and the changing matt, then returned to the lounge where her goddaughter was still waiting in the corner.

"Okay, come here..." Isla called her over, as she unrolled the changing matt, patterned with cartoon jungle animals, on the floor, and smirked when she saw Anastasia's eyes widen in shock when she saw it.

The girl mumbled a nervous question through her panties, with her eyes widening even more when she noticed the diaper and clothes her godmother had with her. She had been bracing herself for some slutty clothes she thought her godmother might be forcing her in for her pleasure, but had not been expecting anything as weird as this!

"Got something to say?" Isla laughed, and pulled the panties out of the girl's mouth, who coughed a little then pleaded with her brow furrowed in concern. "What is all this! Are you actually going to put me in that" The girl said, pointing at the adult diaper.

"Yes, why else would I have it, now lie down on the changing matt."

"But I don't want to wear it, I'm eighteen!"

Isla laughed that the girl thought it mattered. Amanda had been twenty two, and worked as an insurance broker, but that hadn't saved her from the humiliation.

"Aww honey, it doesn't matter what you want. Either you wear it or if you refuse then I'm telling your mom what a heartless little thief you are. Or if you just like to behave bratty than I'm happy to give you another spanking first if that's what you want?"

Anastasia groaned, but knew she had to comply so miserably sat down on the changing matt.

"So is this some weird fetish you have, or are you a spinster bitter you never had a daughter?"

"Why have my own daughter when I can play with someone else's, and all fetishes seem weird to people who don't share them, but I think you'll come to enjoy this... also didn't I tell you to address me as mommy?"

"Sorry mommy." Anastasia sighed, not believing her luck. Not only had she found herself in a position where she could be blackmailed, but her blackmailer turned out to have super weird tastes...

The brunette was made to lie on her back and then lift her butt off the ground so her godmother could slide the unfurled diaper beneath her. It was a plain white one, as Isla had debated picking one of the cute patterned ones but decided to start vanilla for the girl's first one, then try out the various patterns later as she did have the teen for two weeks.
