Visit to Aunty Pat
A trip to Aunty Pats – the journey
The next day after breakfast mum talked about leaving that afternoon after an early lunch to drive over to Aunty Pats. Hermione went to her room to pack for the few days away deciding that she would take some of her school books with her in case there was nothing for her to do, she was quite keen to be ahead on her studies before she went back to Hogwarts. Whilst she was packing mum came in and explained that the journey should only take about 3 hrs. She planned to drive without stopping as she hated the motorway service centres – especially the toilets – as there were so many people using them that they all seemed to smell.
However, there was always the problem of road works which could delay them so they were going to be prepared! She gave Hermione a pair of adult incontinence knickers (diapers) and said she should wear them, not necessarily to deliberately wet them, but in case they got held up and an emergency happed. Hermione looked a bit surprised, but mum lifted her own skirt up and showed that underneath a pair of very staid white “granny pants” she was wearing the special leakproof knickers. If you do what I do and wear an ordinary pair of knickers over the top no one will know if they get an accidental flash! said mum. Don’t worry about when we get there said mum, there is a very nice tea shop just around the corner that if we need to change, we can pop into first and use their loo. I often buy some of their cream cakes to take in with me to Aunty Pats so it is not a problem.
So that is how they travelled west for the weekend. As it was there were no problems with road works and they made very good time to their destination both still totally dry! Just before they got to the tea shop, they were about to pass a public garden/park area and mum pulled in and stopped. Let’s go for a stroll she said, it seems a shame not to use these special knickers – they really are designed for one wearing only – so let’s test them. They enjoyed walking round the park, the flowers were in bloom and it was a nice warm day. They sat on a park bench and just enjoyed the views, there were very few other people around, just some young children and mum’s over in the play area.
Hermione talked to her mum about the wonderful display of school knickers she had seen the day before and also about the reactions of the boys. Mum commented that many males seemed to like school knickers – some even more than fancy flimsy lacey sexy ones – probably it was something to do with what they saw as they grew up and became sexually aware – and for most males it was schoolgirls! This helped Hermione possibly understand what Ron was up to. Hermione was emboldened by her mum’s frankness and decided to share what she had wondered about her dad – “mum, I don’t think dad is telling his real thoughts when he says he “puts up” with you enjoying wetting your school uniform and knickers – I think he really looks forward to it – he certainly enjoyed looking at all the coloured knickers yesterday and I think he checked out my car seat when we got home!
Hermione saw that her mum was looking a bit strange and immediate said to her – don’t worry mum dad didn’t do or say anything he shouldn’t – he behaved just as a dad all the time. Mum smiled and said – no dear that’s not a concern, but it has just dawned on me that you are right about his change in attitude – but it also made me realise mine has changed as well. I will tell you a bit about the start of our play session last night.
I wanted to give your dad a special treat as I know he does not really like me coming to visit Pat. So I dressed up as a schoolgirl like normal, but I put on my sexiest lacy black see-through knickers and black stockings. Instead of standing in front of him while he sat on his chair being a grumpy headmaster and then wetting myself for him to tell me off for being a naughty girl - then spanking me - when he asked me why was I standing in front of the headmaster, what had I done wrong? I tried playing the part of a temptress saying I hadn’t done anything wrong – not yet! but perhaps I could do something wrong in these – as I pulled up my gymslip skirt to flash my black stockings and lacy knickers. (He normally loves me wearing them – especially if we are going out to the cinema).
But he reacted by telling me off for wearing non-regulation knickers, told me to take them off and give them to him and to go and put my regulation school ones on. I willingly did so and when I came back, (still with dry knickers - although I was on the point of bursting), he immediately pulled me over his lap, lifted my skirt and spanked my bum quite hard on my school knickers. He sounded quite fierce and I immediately lost control, pissed my knickers, my skirt front, all over his lap and his trousers. I had been hanging on for a long time and it was a huge flood that came out. As I was pissing, he spanked me hard – but my pussy was starting to tingle and so I pushed it up higher so that he ended up spanking me directly on those lips. I climaxed where I lay on him the last of my pee giving me a final thrill.
I thought I had upset him, but in fact it was the opposite, we ended up on the floor where we were, lying in my puddle of wee. He ripped my knickers off and forcibly took me from behind -and I enjoyed every part of it.
So, from what you were telling me I can deduce that dad certainly has learnt to like seeing school knickers, and me wetting them – but also, I have learnt to like being spanked – especially on my pussy lips. I need to replace my ripped navy blues so a trip to a big store to buy some new colours is going to happen and I think I might just wear them occasionally when I can flash him during our days together. Hermione jumped in at that point and said “Mum as you are playing why don’t you do what I did as a kid and take turns – if we played schools or doctors and nurses’ we usually got to play the role we really wanted first but then we swapped roles around. You should take the role of the school head and get dad to be the naughty schoolgirl! You can get him some school knickers and a schoolgirl costume - if he will not fit yours”. That’s a great idea mum agreed, I may find out a bit more about what he really likes, I would love to see him/her standing there holding the skirt up high with soaking wet knickers and pee running down the white socks.
We had better get moving soon, mum continued, have you peed yet she asked, I have enjoyed doing it while we were talking. Not yet, Hermione replied, but here goes! She started to let her bladder empty and felt the special absorbent material fill with her pee, but then she felt it running out and she jumped up as they leaked all round her legs making her ordinary knickers soaked. Whoops said mum, I need to get you a smaller size next time, mine are fine. Where they were, no one could see them so mum told Hermione to take of both pairs, dry herself with the dry part of her normal knickers then put them into a plastic bag she gave her, then to drop the used incontinence ones into the rubbish bin just near them. Mum quickly slipped off both of her pairs of knickers, dropped the soaking wet ones into the bin and slipped back on her white cotton full knickers.
They walked quickly back to car and got in. The tea shop was a few minutes’ drive and mum manged to park nearby. Hermione got a clean pair of knickers out of the bag in the boot of the car, glad that she had brough three times the number of pairs than the days they were away. They went into the shop and she popped into the loo to put them one. They decided to simply buy several cakes and take them in, so a few minutes later they were at Aunty Pats
A trip to Aunty’s – the visit
Hermione immediately recognised Aunty Pat – whilst she was obviously a little older than she remembered, Pat still had a great figure and almost oozed a strongly attractive feminine charm. She watched her mum and Pat closely embrace and she sense the strong animal attraction between them. Hermione almost expected them to start ripping each other’s clothes off on the spot, but after a long kiss and a longing look, they broke apart. Pat immediately turned and put her arms around Hermione giving her a great hug, but restricting herself to a much shorter and more aunty like kiss on her cheek. But that was enough for Hermione, her legs started to go week and her panties gusset started to get damp – what a woman! thought Hermione, I can see why Mum likes her – and why dad gets jealous.
Just then Pat’s niece burst through into the room and commented “oh Hell, not another one Pat - don’t you ever stop! Pat turned to mum and Hermione and said “this is Antoinette – or as her parents call her ‘Princess’, she is staying with me for a while as her mum, my sister, is not well and needed a break. Princess managed a quick churlish hello to Mrs Grainger, looked down her nose at Hermione and said “don’t expect me to baby sit this one for you Pat whilst you are off having fun”. She then just turned around, walked back out and firmly shut the door with a passing comment “see you at dinner!”.
Hermione stood there with her mouth open for several seconds before pulling herself together. She looked at Pat and asked – “how old is “the princess” then please?”. “Just coming up to 16” was the reply – “but that is only a few months older than me” Hermione spluttered, I would be expelled from school if I spoke to an adult like that and I strongly expect I would get grounded for a year from you or dad!
Pat smiled, but rather wearily and said my sister was brainwashed into the “let them run wild so they can develop themselves and not end up supressed” group. Her husband – for the short time he was around – took no interest in her at all and this is the result. I must be honest and admit I am really struggling especially as I never married (you know why) and I have never had my own children. I am open to ideas but I think it may be too late and the only correction she will get will be from the police! Nothing I have tried has worked at all! – and then she burst into tears and Hermione’s mum quickly gave her a big long hug until she stopped sobbing. We will need to have a proper discussion about this, Pat, but try to relax for now and let’s catch up. Hermione immediately realised that the universal British remedy was needed, so she found the kitchen and made the three of them tea.
When she got back to the room with the tea, Pat was in full flow about what it had been like since “The Princess” had arrived, Pats two “flat mates” (by which even Hermione realised meant “bed mates”) had left for an indefinite time so Pat was enduring the problem on her own and without and adult support, (which Hermione guessed meant no sex). The cream cakes were brought out and disappeared with the tea by which time Pat was a bit more composed, but obviously still upset.
Pat shook herself and apologised for being such an appalling host, I have not even showed you your rooms and allowed you to unpack and freshen up! The house was a big old Edwardian one with four floors and lots of stairs! Mum was shown in one room on the second level and Hermione up one more level to a smaller, but very comfortable room. Pat showed them where everything was, there was a bathroom and a separate toilet on each level but Pat made a point of showing them that under the bed was an old fashioned “goesunder” (chamber pot) just for emergencies. She also pointed out that the beds had protector sheets fitted as she knew accidents could happen!
When Hermione and her mum were alone together for a few minutes Hermione said it seems unfair that Aunty now has to sort out dinner for us all – but I don’t think she would like to go out, I suspect she wants to talk more with you for a while. I saw a Fish and Chip shop just a short walk away as we drove in, how about I go and bring us all in some for tea? Mum was really pleased to see how thoughtful and caring Hermione was becoming as she grew up and agreed. They told Pat when they went back down stairs and she was visibly relieved. Pat went up to talk to the princess and once everyone’s order was sorted Hermione walked off down the road. She enjoyed the few minutes on her own, trying to get her thoughts into some form of order and to see what she could do to help her mum and Pat. Lots of spells came to mind, but she knew they were not allowed so some other approach was needed. In the end she decided to let things ride for now, to be quiet and listen before offering any ideas.
When she got back, she found that Pat was improving and had got her best bone-china and silver cutlery service out just for fun, also she had some beautiful lead wineglass flutes on the table, but they were filled with sparkling grape juice – Hermione later found out that the princess would secretly drink any alcohol she could find so Pat had cleared the house out completely - in spite of her liking the occasional glass of wine herself. The meal started fine, but the princess soon started making comments like “the chips are cold (they weren’t) - did you get lost or were you distracted by all the things in the shop windows”.
She was worse when Pat and mum started to take the washing up out to the kitchen and she was on her own with Hermione when she said that time Hermione had taken probably reflected her slipping down an alleyway to let some boy pull her knickers down for a quicky! Hermione was so surprised she just stood there open mouthed which gave the princess time to continue – looks like I got that right and you enjoyed it! - has his spunk leaked into your knickers yet? (assuming you are wearing some). Pat came back at that moment and the princess slipped passed her and disappeared upstairs to her room. Pat asked if everything was ok and Hermione recalling her decision to wait and listen simply said “I’m fine”, and went to help in the kitchen. After tidying Hermione said to mum and Pat I’m tired so I think I will go up to bed and read for a while, you two can catch up. But before that what is happening tomorrow – I think mum said it was the reunion opening ceremony so I guess you two will be going. “Yes”, said Pat “it would be good to go and meet old friends. It starts at 11, followed by lunch, there are sessions in the afternoon but they do not look very interesting and I was thinking of coming back home so we could get to know each other a bit more – I promised your mum I would talk and show you about girl things that might be a bit strange if she did them.
Could you try going out with the princess for this time – she will no doubt be meeting her friends at the shops so I will provide money for lunch, it should only be for a couple of hours, perhaps she will start to appreciate you as a person”. Hermione was in no doubt of the unlikeliness of this happening, but politely agreed to give it a go. She went up to her room and decided to be careful and locked the door. She was very tired, somewhat upset and puzzled by the princess, but recalled the attraction to Pat when they first met and lay on the bed, fingers in her knickers gently rubbing her pussy lips.
Wary about making a mess she investigated the “goesunder” and tried squatting over it still rubbing her pussy, but with her fingers now outside of her knickers. It was very different squatting low over the bowl and as she let her pee out her into the crotch of her panties she felt a great deal of pleasure – probably as a result of the tension in some of her leg muscles against the act of letting her bladder go. Initially everything was fine, her panties held the initial flood before the wee burst through, but then she felt trickles of wee running down both legs to her feet and when she had finished there were two small puddles where her feet had been.
She took her panties off and used the dry part to mop up the puddles, ringing them out into the pot when they were fully wet. She checked outside of her door for anyone being around and then quickly took the pot down to the bathroom to empty, she washed her panties and herself before heading back to her room. One clean pair of full brief knickers later she was in bed and went to sleep as her head hit the pillows.
Out with the Princess
The morning was a bit a rush, but quickly enough Hermione and the princess left the house to catch the bus to the local shopping centre to amuse themselves for a few hours and have lunch out. The princess continued to make it clear that she had no wish whatsoever to have company alternating between making snide comments to Hermione and pretending she was not there. Things quickly got worse when they got off the bus when Hermione realised that the princess had arranged to meet a group of her friends at the bus stop and she proceeded to insult her to them all. It was quite a large group – more of a gang – and Hermione had her work cut out to not retaliate as she was pushed and shoved around.
They headed for a big department store to start with - but they had hardly got inside the doors when security appeared and escorted them out – reminding the princess loudly that she and her friends had been caught shoplifting last week and were banned from the store. Hermione was careful to keep a short distance away from the rest when they went into other shops as she could see small items on display disappearing when the girls went past. Lunch in MacDonald’s was just as bad for her drinks got “accidentally” split on her lap, down the back of her neck and one girl even managed to drop fries down the back of her neck.
After lunch Hermione simply stated she was going back to Pat’s house as she was to meet her mother to plan the rest of their trip, she had checked the bus stop locations and knew which number to catch and just marched off to a round of very rude cat calls.

How to deal with the Princess
On the bus back she thought about the princess and to put it basically she realised that she was “really getting on Hermione’s tits” – beautiful and perfect as they were – but she was such a rude nasty irritating know-it-all trying always to put Hermione down, show her up in front of others, and generally behaved as a pest. Hermione was really pleased she had not taken her wand away with her as the temptation to use it, (and almost certainly being caught by the department of magic and getting in trouble), was so great. Just a few simple spells – the clumsy one so she knocked things over or the puking one – right in the middle of McDonalds or the shops in front of the rest of her “rat pack”! – she certainly deserved it.
Then the light went on! – she could not use magic as such, but much of potions was learning about how to use everyday products like plants in a way that caused a reaction when taken by a person. Certainly, some potions like Polyjuice needed more than a touch of magic, but many did not. And which book had she brought with her? – next year’s prescribed course book for potions.
The next time mum and Pat went back to the reunion she said that she would be staying in the house and would be studying ready for next term – she said it was Chemistry as it was the nearest muggle subject. Mum said you never let up do you – please take a few more days’ break. Pat looked amazed that a girl of her age would spend holiday time studying at all – let alone Chemistry - and said “why can’t some of you rub off on the princess”!
Hermione really put a lot of study into what potion to make. There were some pretty spectacular ones around bodily functions that she kept coming back to – the idea of setting a time delayed potion that would cause the princess to lose bodily control at both ends at once was so tempting – the thought of her standing in the middle of MacDonald’s in front of all of her friends throwing up at the same time as filling her knickers and then wetting herself was just brilliant. But Hermione realised that whilst it would be great, it would be a ”one off” event, and knowing the princess she would probably turn it around and claim she had been poisoned by their food and management would then give her free vouchers!
Then the thought hit her – it was triggered by Pat’s comment about some of her rubbing off on the princess. Why not go to the other extreme and produce a potion that would make her super nice to everyone – her nasty friends would soon abandon her. Pat would appreciate the change and it may stop her ruining the rest of her life. More research studies and a potion was found – one that lasted for at least a week at a time and only needed a few drops to trigger it again and keep it going. The notes even indicated that if taken long term it could become permanent! The hardest part was translating the ingredients from their magical world names into muggle English, but finally she produced a list of them – most were easily bought in the food shops or chemist. One was hard – a particular plant, but careful checking found that it was a common hedgerow item, so armed with a picture from an encyclopaedia she went hunting across the local park finding plenty down the back of the compost bin area.
Cooking it all up looked like being a problem, but when Hermione had a look around the garden shed she found a small gas cylinder fuelled camping stove that must have been kept in case the power went out. With some careful timing she managed to produce the completed extract and put it into an empty medicine bottle that was in the bin. Being careful not to take any significant quantity of the liquid she smelt and just tasted it – there was no small or taste! At evening meal Hermione was her usual helpful self which made dropping a small quantity from the bottle into the princesses’ drink easy. Hermione was very disappointed (and worried she had failed) when there was no change in behaviour that evening and she went to bed re-assessing the “both ends at once” potion.
Success
The shock that hit them the next morning was huge! Pat, Mum and Hermione came down from their rooms (or rather Mum and Pat came from one room!) into the kitchen to find the princess was already there – and on the table was a full cooked breakfast, tea and coffee, all laid out neatly and looking spectacular. There was a moment of silence followed by a Wow!. The three of them all heaped praise on the princess who just stood there and beamed! The four of them had a most enjoyable meal and conversation and at the end Hermione had to almost fight to be allowed to help the princess clean up.
The princess insisted that she wanted to say home to sort out her room and so Mum, Pat and Hermione went out in mum’s car to look at some of the local sights. Once they were on their own Pat and mum both asked if Hermione knew anything about what had happened – it was wonderful, but they were worried. Pat said “I know from things that your mum mentioned that you are a witch – yes, I do know a little about the magic world as I have had very close girlfriends who are witches”. Mum said” but you told me that you would get into trouble if you did any magic – you are not going to be punished are you”.
Hermione explained what had happened, that she had not used actual magic, just the knowledge of potions she had studied. She explained that each dose of a few drops would last for about a week and that she had brewed enough for 6 months use so all Pat had to do was administer it each week. It is likely that 6 months of drops will be enough to cause a permanent change, but I will prepare some more and send it to you before you run out, just in case.
Mum and Pat were relieved that Hermione would not get into any trouble, but then asked how she got the idea to make the princess nice. Hermione told them about her investigations and the temptations for other things – they both laughed at the “both end at once” potion with Pat saying there were a few people she knew who deserved to be given that one!
Lessons from Aunty
With the princess problem solved Pat said - I am forever in your debt so can we start sharing my ‘girls pleasure knowledge’ with you tonight? Feeling relieved that the problem had been solved Hermione said she would love to start learning more about pleasure for herself.
Hermione firstly checked with her mum that she really did not mind her special friend teaching her sexual tricks– she was worried that her mum would be upset about Hemione taking Pat’s time away from her. Mum assured her that learning from Pat was a great way to grow up into a strong independent woman who would understand her own body and how to get and give sexual pleasure.
After dinner, Mum went to her bedroom and Pat took Hermione up to her room where they sat on the bed. Pat started the conversation by complimenting Hermione on her figure and also explained about always agreeing a special safety word to say when “doing sex things” with anyone that would mean an absolute stop to whatever was happening.
Having sorted that out, with Hermione’s agreement she slowly started to undress her and taught her the wonderful pleasures that can be achieved by going slowly - she spent many minutes gently kissing and licking all around her firm breasts, gently circling them getting closer to her nipples but not quite touching them. Hermione had never known quite how firm her breasts could become – or how firm and erect her nipples could stick out – then she realised she was moaning softly absolutely desperate for her nipples to be touched, licked, sucked - then when Pat did just that it was like an electric shock ran from them to her pussy making it ache for some attention. Pat slowly moved down from Hermione’s nipples kissing and licking her all the way down – almost to her pussy – but then repeating the kissing, licking and caressing all around her pussy lips getting closer to her clitoris but not touching. Hermione realised though the waves of pleasure that her clit has as hard as her nipples – a totally new sensation for her. When Pat finally kissed then sucked on her clit Hermione exploded   with waves of pleasure at least equal to when she lost control on her broom when flying.
The it was her turn to try to do to Pat what had been done to her. Either Pat was very sensitive - or Hermione was a good student - as Pat reached a shuddering climax almost the moment Hermione started to suck on her clit.
By this time both of them were fairly wet and there were a few damp spots on the sheet, but Pat had not finished yet. Pat said that she knew the Hermione enjoyed wetting herself (as she also did) and there was a special fun way of doing this – she asked if Hermione needed to pee yet which she did – but was not desperate. They had several drinks of water whilst they chatted about all sorts of things including Pat telling Hermione how wonderful her mum was and how much she enjoyed getting back together.
Before long Hermione was starting to squirm a bit which Pat instantly noticed. Pat told her to put her knickers back on and lay back on the bed, which she did. Pat then repeated what she had done before – but even slower - after half an hour she was just moving her lips away from Hermione’s nipples and down towards her pussy and Hermione’s bladder was screaming for release.
The second Pat touched the tight material of Hermione’s knickers over her pussy Hermione lost all control, she climaxed, shaking like crazy and as she did so her wee exploded out not just filling her knickers but with such force that it went straight though in a graceful arc over Pat’s face. Pat didn’t move but licked the wee sensuously. As soon as Hermione recovered Pat said please do the same to me, I am dribbling into my panties already and you have already got me feeling so randy I need a quick release. Hermione happily agreed and dived down and sucked on the little wet patch in Pat’s white lace panties which almost instantly were totally flooded as Pat came to her own shuddering climax. Hermione decided to copy Pat and licked her lips to taste Pat’s wee and realised she liked the taste as well.
The bed was awash by now, but they quickly rolled up the sheet and the protector, putting them in laundry bag to take downstairs later. They then went into the shower together in their wet knickers and Pat showed Hermione how to gently soap and massage each other, both of them reaching a gentler, but still satisfying, climax under the shower.
Hermione thanked Pat for all she had shown her and all the pleasure she had enjoyed, but said I don’t want mum to miss out with you so I will tell her I am going to my room. I hope you are not too exhausted as I am sure she will want to spend the rest of the night with you. That’s kind of you said Pat, we are such old friends that we can just enjoy cuddling sometimes, although that can start things in itself.
Hermione wrapped a towel around her, picked up her clothes and left, she popped into her mum’s room and told her that “lessons were over” and she had really appreciated Pat’s attention, but she was mum’s special friend so Hermione was heading for her room. Mum saw how happy Hermione was and how pink her body was, you really are growing up very quickly she said – I know I shouldn’t ask but would you drop your towel for me to see you? Hermione was so pleased that mum had asked and let her towel drop standing totally naked. Mum looked at her and said you are absolutely beautiful, go and make special friends with girls or boys of your own age, whilst Pat and I don’t seem too much older now in just a few years and we will start to fall apart – don’t let yourself get locked in with an older person it can be very hard.
Hermione went to bed and slept sound.
The journey home was prepared for as the journey out, incontinence pants under granny knickers. Because they were all having such a good time, they were a bit late in leaving (with Hermione promising a second batch of potion in good time before the existing batch was used) so they hit the rush hour traffic which was made worse by a vehicle accident at the narrowest road as they got close to home. That accident led to two others- one each in Hermione and her mum’s knickers, but the incontinence pants did their job perfectly this time.
