Grandmother Started It All

Fiction Story

Title: Grandmother started it all

The language is mainly British English and where possible I will put in brackets the (American English) equivalent.

All characters are fictitious and are all over 18 years of age.

How it started

All this happened so quick and fast that I will go directly into the story and fill in details and flashbacks as the story proceeds.

It was a Saturday morning when mum (mom) received a telephone from her mother, that is my grandmum (gramma). The call was short as it seems that grandmum needed some help quickly.

Mum asked me to go to her house as she was not sure what grandmum wanted exactly. As at home, they call me Mr Fix It All, mum told me she was sure that whatever grandmum needs I can do something to help her.

As grandmum lives on the other side of town, I took the bus and in about 20 minutes I was knocking at her front door.

When grandmum came to open the door, she was wearing her dressing gown (bathrobe) and a worried and surprised look on her face.

“Oh! I was thinking that either your mum or your sister would come” she greeted me.

“Mum was not sure what you needed. She mentioned you have a stool stuck somewhere and asked me to come over to unstuck it for you.”

“Oh my God! What a mess I am in. I am very embarrassed as there is a huge misunderstanding.”

“What misunderstanding?” I asked grandmum.

She grabbed by my shoulder and pulled me inside and closed the door quickly behind me. She then asked me not to laugh or reducible her for what she was about to show me as she was already feeling very embarrassed. I promised I will not do anything to embarrass her. She turned around, bent down and lifted her dressing gown exposing her naked arse (ass). She parted her cheeks to reveal a bit of stool coming out of her anus.

“Grandmum, do not feel embarrassed but I need to laugh not because of what I see, but because of what mum understood by stool. You referred to the human waste while mum thought you were referring to a piece of furniture.” I told her and I heard her giggle.

“I was sitting on the toilet for hours and forcing pooping, but this, what seems to be a monster, got stuck and would not come out. I tried to push it back in but it was very uncomfortable and I cannot manage to pull it out either. Can you think of something to help your grandmum out of this mess? Let us go to the bathroom where I prepared some gloves for your to wear. I am sure it is not something nice to touch with your bare hands”

We walked to the bathroom and she showed me where the gloves were. I told her that I need good access so I asked her to kneel, bend down with shoulders down to the floor, legs spread and arse as much as possible up in the air. She was quick to take the position I asked of her. I was surprised as it is quite an embarrassing position for anyone to be in. She told me that she felt embarrassed but she would sacrifice and pay anything to get out of her discomfort.

Let me give you some background here. Grandmum got pregnant with my mother when she was 14 and gave birth to my mother when she was 15 years of age. My mother was no better as she got pregnant with me when she was 15 and I was born when she was 16 years of age. At this point in the story, I am 20 years old, my sister is a year younger and 19, mum is 36 and my grandmum is in her early fifties — 51 or 52 if I am not mistaken. She has a stunning body that makes younger women envy her. She looks more mid-thirties and people would confuse her to be my mother’s sister not her mother. My friends are jealous that I have such a young and good looking grandmother. It was not the first time that I tried to spy on her when she went to have a shower or to change her clothing either before going out or upon returning home. Now I have her exposing what I longed for to see. I decided to try my luck and removed her dressing gown and exposing her fully naked body. I felt relieved as she did not complain.

Now back to work, and I wore the rubber gloves and put some baby oil to lubricate them. I tried to insert a finger between the stool and her anus lining wall. She asked me to stop as I was hurting her and she could not take that kind of pain. I told her that I had no idea how I am going to get that thing out, if I cannot insert my fingers in her anus and pull it out, I need to push it out but how can I do that I asked her. It seems that surprises come in bundles. She explained that when she visits her gynaecologist he inserts his fingers up her vagina to feel what he wants to check by pressing the fingers inside her vagina and the palm of his hand on her tummy. She asked me to slide my hand inside her vagina and try to feel the stool from there.

I tried several times to insert more than two fingers inside my girlfriend’s vagina and never managed as she would complain that I was hurting her. I told grandmum that I was concerned that sliding my hand in her would be painful. She assured me that she inserts bigger toys in there when she plays with herself. She confessed that she even inserts wine bottles when her toys are not handy. She told me to do it as she was feeling embarrassed confessing what she does in private.

She spread her butt cheeks revealing a pair of small cute shining pink inner labia and a conspicuous clitoris that was big enough that her clitoral hood was unable to cover. It was time that I abuse again and I removed the glove from my left hand, put some oil to lubricate it and parted her vagina opening to check the size of the hole. It was quite sizable and I believed her when she said that she inserts even wine bottles. My hand slid in without any big effort. I took the opportunity to feel around and I felt her cervix. As my job was to feel the stool from the inside, my hand was supposed to explore the side towards her back and I did not risk go and try to hit her G spot. Oh! How I wished to take out my mobile (cell) phone and take a photo of my hand inside her up to my wrist. Honestly, I was abusing her more than helping her as I did not feel anything that might move her blockage. After a short while abusing her I told her that I did not manage and removed my hand from inside her.

I suffered from constipation and since I was a little boy and it was nd it still is a weekly ritual on Sundays and sometimes even on Wednesdays that mum would take me to the bathroom, ask me to undress and give me an enema under the frequent watchful eyes of my sister who, as I said, is a year younger than I am. Having my sister present does not bother me much as since I remember, mum always bathed us together and when we grew up accustomed to seeing each other naked and when we commenced taking baths on our own, we had several occasions to appear naked when she or I would walk from the bathroom to the bedroom.

I remember mum always telling me that I followed her footsteps as she too suffers from constipation and her mother too administered her an enema every now and then. I asked grandmum to remain in that position while I fetch the enema bulb. I thought to myself that grandmum would make a very good obedient submissive as she did not budge an inch from that awkward position.

Grandmum was instructed that I will be spreading a little bit of her anus hole and pour some baby oil in the gap to lubricate that blockage and perhaps she would manage to push it out herself in the normal way when she tries pooping. She felt some discomfort as she complained a few times during that operation.

When she tried to remove the blockage by pooping and she did not manage, I had to tell her that the only way I had left was to insert the enema tube and fill her with water. I had to fill the enema bulb twice and she refused the third fill as she was not only hurting when I inserted the tube in her but also the water was now having uncomfortable effects on her intestines.

I slid my hand between her spread legs and rubbed her tummy to move the water inside her and rub her clitoris with my arm. She realised what I was doing and called me a naughty boy but did not ask me to stop.

After a few minutes, I asked her to sit on the toilet and push out the water as hard and as fast as she can. When she sat on the toilet I admired those beautiful full breasts of hers. Her nipples were quite large and stiff. I wished I could take them in my mouth and suck them. I heard the gushing of water in the toilet and a scream. Then a pop sound in the water.

“Oh! Thank goodness, it is out. Oh! How much I am grateful to you and I do not know how to pay you back. I am in pain inside there as I felt something scratching me while it was coming out.”

“Grandmum, do not worry, it is something I experience when the size of my stool is quite thick, it will soon pass and you feel normal again. Earlier you told me that you sacrifice anything and pay anything. I know I may be asking too much but you have such a beautiful body, I would like you to be my naked submissive girl.”

“You dirty little boy, you don’t beat about the bush — do you,” she said smiling. “I noticed that you like what you see and you want to have more of it.”

“Yes please, grandmum, whenever we are alone together I want to enjoy your company while you are naked.”

There was a long pause and she kept looking at my face with a smile, then she said, “You undressed me with my approval, not complaining is a sort of approval, you are seeing me naked now and with my consent and you fist fucked me, in a sort of way, also with my consent or rather by my invitation, you made me stay in a very embarrassing position for a long time, also without any complaints from me, and you inspected and touched my private lady parts, also without me complaining, so I do not think I will find any objection to being naked in your presence when we are alone as I am right now.”

By this time she had finished her job sitting on the toilet and told me she was going to have a shower and asked me to leave the room. I told her that was admiring and looking at every curve and crack in her body that I was going to stay there and watch her as I was enjoying what I was seeing and she just accepted being naked in my presence. She smiled at me and stepped into the shower cubical.

While she was having a shower, I asked her if she saw the film (movie) ’50 Shades of Grey’ and she replied in the affirmative. I asked her if she remembers the scene where Christian Grey asks Ana Steele when she was told to kneel and sit on her feet while being naked, place her hands on her thighs and greet and wait for him in that position whenever he will come to her.

“Yes, I remember that scene and I had some fantasies, which fantasises perhaps are now going to be fulfilled” she replied with a giggle, “my guess is that you are leading me to such proposal.”

“That is fantastic. Thanks, grandmum. I will try and visit you weekly instead of fortnightly and I will phone you before to tell you the approximate time I will arrive so you will prepare yourself for me naked in the hallway. Now, before I go back home, and if you do not want anything else from me, let us agree that you had some drain blockage and I managed to unblock it for you.”

She laughed loudly and said while going out of the shower “A perfect explanation of the situation that will not embarrass me to tell your mother.”

I told her I was leaving, but before I left I went behind her, wrapped my hands around her and grabbed those lovely melons, I kissed her on her neck and said goodbye till the next weekend.

That was another sign from her of her submissive acceptance as when I was grabbing her breast she placed her hands on mine and squeezed my hands tighter on her breast.

“Goodbye dear,” she said, “and next weekend I may have some pleasant surprises for you to fulfil some other fantasies I have.”

“Do not worry grandmum, I too have some fantasies I wish to fulfil, so I am looking forward to next weekend. But one final thing before I leave, I would like to see all your sex toys.”

“You want to see what I do with them, I suppose.”

“No, grandmum, I just want to see your collection. There is ample time in the future to enjoy watching you do that.”

She picked up her dressing gown and started to put it on, and I reminded her that she promised me to be naked all the time when we are alone, and we are still alone.

“You are a naughty girl,” I told her while I slapped her naked bottom.

She smiled and folded it on her arm. She walked me to her bedroom and opened the bottom drawer of the vanity unit and emptied the drawer on the bed.

“I see you have quite a variety of dildos and vibrators and I see some other toys also. We will get to all of these as time goes by.”

Weekend of experimentation and fun

While sitting on the bus on my way back home, my mind was only thinking about her naked body and what was achieved in such a short time in our relationship.

I could not remove from my mind the size of her pussy and how my hand slid in it so easily. If she managed to widen her vagina to that size by inserting various objects, I would work to widen her arse hole too. I noticed that she did not have any butt plugs or anal toys in her collection. I decided to stop at the town centre and visit our local sex shop. I bought a set of butt plugs ranging from a small one, the size of my index finger in grith up to one which was bigger than my shaving gel can.

I also bought one of those metal butt plugs with a green glass ornament at the end. Green is grandmum favourite colour. I saw many pictures of girls pantyless and sporting one such butt plug in public. We will see how things go, I will take it slowly and let her feel comfortable in whatever I ask her to do. As the saying goes — ‘In for a penny in for a pound’ — I also purchased a vibrator with remote control. I think this may be fun if grandmum wears it in public and I control her orgasm.

As soon as I arrived home mum greeted me with the question of whether everything was OK with grandmum.

I told her that there was a misunderstanding as grandmum was referring to stool or poop and she, mum, thought it was the furniture. She laughed and asked if the problem was solved. I assured her that the problem was solved to the satisfaction of grandmum.

At least she did not ask me what I had in the shopping bag I was carrying. It would have been a hard time to explain why I bought the butt plugs for.

The days to the following weekend passed at a snail pace. All week my only thoughts were about grandmum down on her knees waiting for me naked. The surprise she said she had for me and the surprises I planned for her. I had a couple of warnings at work as I was not concentration properly on the job I was doing.

What surprised me was how much she was relaxed naked. Picturing back every word we exchanged and every situation, I remembered that I did not see any bikini tan lines on her body, but she had an even tan all over her body. I will ask her if she goes to a nudist beach.

Saturday arrived and I told mum that I was visiting grandmum as I promised that I will go. Mum was pleased as she said that her mother feels lonely after her husband died in an accident a few years ago.

I picked up the shopping bag with grandmum’s new sex toys and left to catch the bus. When the bus reached the town centre, I called grandmum from my mobile phone and informed her that I will arrive in about ten minutes. She replied that she was ready for me at that very moment and all she needs to do is to walk near the door and wait for me there, naturally the way I asked her to wait.

So she was ready for me at that very moment she said. I wondered what she had in mind. Was she excited and stripped naked since early morning to wait for me, or else perhaps she likes running around naked when she is alone at home. I do not think I will ask her this question. Perhaps if the right situation comes up, I may pop up the question to her.

When I arrived, she opened the door ajar and asked me to enter without opening the door further as she did not want to be seen naked and in a submissive position by any of her neighbours or passers-by.

I locked the door behind me and told her that I had a surprise for her and presented her with the shopping bag.

“I will have a look at your present later if you do not mind. I have a surprise for you myself,” she said while she unzipped my trouser’s fly and reached inside and pulled out my penis.

“Grandmum, what are you doing?” I asked

“You just keep quiet as this submissive is going to please her master,” she replied.

She gave me a blowjob that none of my ex-girlfriends ever gave me. She broke the ice on intimate sexual matters, so I felt more confident to abuse her body myself. I asked her if she wanted me to warn her when I was about to come, but she said that she enjoyed the surprise of suddenly feeling the cum in her mouth, so I just bit my lips and remained silent as I felt I was about to shoot. She swallowed the lot, then she got some tissue paper, which she had prepared close to her and wiped my throbbing shaft clean and pushed it back in my trousers (pants).

“Did you enjoy it?” she asked

“How can I deny such pleasure, I am drained and speechless,” I replied. “Now have a look at my present.”

She opened the larger box containing the set of different sized butt plugs. She looked at me and while thanking me, she informed me that she never had anything enter that hole except for a small candle. I explained to her that if her vagina managed to open so much over the months, perhaps years of inserting different sizes of toys, her anus would also be trained to accept bigger toys. In that way, it would help if something similar to the previous Saturday would happen again. Her hole would be wider if some other thick stool got stuck.

I took her hand and gestured her to stand up and walked her to the kitchen. There, I asked her to kneel and wait for me. I went upstairs to the bathroom and fetched the bottle of baby oil. I need good lubrication to insert even the smallest butt plug in a virgin arse hole.

She followed my instructions without questions when I asked her to take the same position when I administered the enema to her. I told her that I was going to lubricate her hole with lots of baby oil and insert the smallest plug into her. I told her not to confuse being uncomfortable with pain, and she should only tell me if I hurt her.

Giggling I told her that I was about to fuck her arse with the butt plug, while I slowly inserted it slightly and took it out again and trying to insert it a little deeper each time. It was not difficult to insert it as it is small and there would be little pressure on the muscles surrounding her hole. At least I did not hear her say that I was hurting her.

I asked her to keep the plug in place and continue with her housework in the normal way. Also, I advised her what the shopkeeper told me, that she may feel a little discomfort at first, but she will also feel horny as she moves and walk around.

Placing the remaining butt plugs on the kitchen table, I asked her to sit down and we have a chat about the subject. She picked up the biggest and said that no way will find the way inside her. I laughed and told her that like her pussy, by time and training she would be able to insert it. It may take weeks or perhaps a couple of months, but I was sure that the body would adjust. What is important, the shopkeeper told me, is that when you upgrade from one size to the other you must do it immediately one size comes out the other goes in, as your hole would be opened and not give it time so the muscles would contract and the hole would close again. If it closes again, it will be painful to insert the larger plug.

She then took the small parcel from the shopping bag and placed it on the table.

“Open it,” I said, and that is what she did.

“What is this?” she asked.

I told her that it was a different type of butt plug, more elegant so it may be worn in public. She looked at me and asked if I was expecting her to go naked in public sporting that inside her. I explained to her that she does not have to go naked, only go out in a dress or skirt without wearing any panties. When you feel like it, you can lift your skirt and pretend someone is watching you. It makes you feel hornier.

“Grandmum, have you watched the French film ‘Histoire d’O’? I asked

“No, why” she replied.

“Well, the story is like Anastasia Steele becoming a submissive with certain conditions, the character O became a complete submissive even to have strangers abuse her and whip her just to please her master. She was even branded with a hot iron with the initials of her master to have a permanent mark that she belongs to him.”

“I hope you do not have such sadists thoughts going through your mind.”

“No grandmum, but some rules that O had to obey at all times.”

“What kind of rules?”

“Well, the few I remember are that she was not allowed to wear anything under her dress, that is no bra and no panties; she was to sit with the flash touching the seat so she had to pull up her skirt to sit down; she had to sit with her legs apart and never cross her legs and all this she had to do even in public. These are not sadistic rules I am sure, but a challenge depending on the situation.”

“And you want me to do that?”

“Not wearing a bra and panty is not a big deal. Several women do that. Sitting with your legs apart is also no big deal. Legs apart do not mean wide apart but just that the knees are slightly separated and do not touch. Well, the last one is more daring and if you are in a restaurant and sitting at the corner table, no one would notice if you lift your skirt to sit, but if you are at a centre table you will be noticed from every angle, so I save you that embarrassment. Are you prepared to do that for me, grandmum?”

“Well, as you said, except for the last bit, it is not a big deal and if I have the option to chose to lift or not to lift my dress then I do it, but if you force me against my will to lift my skirt in public then I will not do it. Here I am more like Anastasia Steele than O, choosing what conditions to accept” she said giggling.

“Good, go put a dress on. Find one with a short skirt and let us go to the supermarket (mall) and have some fun.”

“Shall I keep this butt plug in me or shall I wear the elegant one?”

“The elegant one is bigger, try inserting it in yourself so you can control if it hurts you. Remember that discomfort does not mean pain.”

She removed the butt plug that was inserted in her and lubricated the metal one. I reminded her to wash well the one she removed. She squatted and spread her knees wide to allow her arse hole muscles room to expand. To my surprise, after a little time and with a lot of lubrication and facial expression of agony, she managed to insert it.

I asked her to stand up and bend down so I could have a good look at her green imitation jewel. Telling her she looks great and also that she was not completely naked as she was wearing something. She laughed when I told her that she was wearing something. She walked in front of a full-size mirror to have a look at her new toy.

“This is making me hornier than the other when I walk. It feels a bit uncomfortable but I am sure I will get used to it shortly.”

“That is exactly the purpose of that toy. And yes, you will get used to it and forget you are wearing it. Now for that dress. Go put on a sexy provocative one and we will be on our way. And one other thing, that butt plug is approximately a little bit bigger than the size of the second butt plug in the set I gave you, so you see you already advanced one size up.”

She just looked at me and smiled, then she went upstairs and returned wearing a sexy although not provocative green dress. She told me that she chose this dress as the fabric is not light and blows up with the slightest gust of wind and also the skirt part is not wide to allow the hem of the dress to fly high.

Before we left the house, I asked her to bend down and spread her pussy. She asked me why and I replied that an obedient slave should just follow the orders of her master. When she presented me with her gaping pussy, I informed her that I was going to insert in her a vibrator that I can control by remote control. “You are making life more interesting,” she remarked. I pressed the remote control button to test the toy and she screamed as she did not expect the vibrator to go live inside her.

We drove to the supermarket and parked the car in the car park (parking lot). When we got out of the car we discovered that it was windy in that open space. Grandmum was not happy as although she chose a particular dress to avoid the wind exposing her nakedness under the dress, her skirt was flying high exposing her naked bottom half. I told her to gather some of the skirt’s fabric in her hand so that it will be tighter to her body and the wind will not lift it. She reminded me that she is a girl and knew exactly what to do in such situations as she had decades of years of experience wearing skirts on windy days.

We went into the supermarket and I began to dare grandmum to bend down and fetch something from the lower shelves while I stood behind her to watch how far the skirt would rise and how much would be exposed and also to protect her from the eyes of the others shoppers.

Being close to her, I told her that I could not see under her skirt so I dared her to bend down again when I was a bit further away. She waited until there were no shoppers in the lane we were in and then she bent down. From a distance, I could catch a glimpse of her vaginal slit and the vibrator antenna coming out of her vagina, but not as far up as to catch a view of the butt plug.

We went to the coffee shop to have a cup of coffee and I commenced teasing her by pressing the remote control button and increasing the intensity. At certain times, the agony on her face gave her away. She asked me to lower the intensity and I showed her that my hands were empty. “Probably the toy is faulty and I need to take it back to the shop,” I told her.

I was approached by another man, in his early 20’s and asked me to have a word with him in private. I excused myself with grandmum and this man whispered to me if I had a vibrator control and was controlling the lady accompanying me. I confirmed. He told me that this is the third time it happened to him. He explained that at certain times his girlfriend was feeling the vibrations of her vibrators while I was not pressing the button, then he realised that there is someone else who has a vibrator on the same waveband as his. He continued that to find out he asked his girlfriend to turn her vibrator off and then he set the remote to the full intensity and looked around to see any reactions from any female, and noticed that my partner reacted to his control. “Oh!, I thought that there was something wrong with my vibrator and I was going to take it back to the shop to complain that the thing vibrates even when I am not pressing the button” I told him. “No, do not worry, it is just that it appears that there are a number of these things on the market with the same waveband as it happened several times,” he replied.

I invited him and his girlfriend to join us and we will have some fun watching the ladies react simultaneously to the commands. While he went to fetch his girlfriend I informed grandmum what happened and that the couple are going to join us and they both be under our control. She did not seem too keen but told me that this may be fun. I told her that if she felt that the other guy may go overboard, she should switch off her vibrator and switch it on again when we leave.

When they came over we introduced ourselves and the girl put her hands between her legs telling us that she was switching her toy on again. We spent about thirty minutes alternating who would press the button and watch the reaction of both ladies. At one point this girl squitted and we thought that was the time that we should stop. Later grandmum complained that she was still simmering and did not boil like the other girl. So we went to another spot away from the couple and I continued teasing grandmum till she told me that she was exhausted and needed a rest.

When we thought it was enough for the first time almost naked in public, we headed back home. I told her I was easy on her with the vibrator as I could have made her drop on her knees with the vibrating intensity and she reminded that if she were not sitting down she would have dropped on her knees when the other boy pressed his remote.

When we arrived home, she was horny and I was even hornier with a hard member that needed relief. I made her kneel, lifted her skirt, removed the vibrator and fucked her hard.

She told me that she was not expecting me to fuck her, but I told her that she agreed to be my submissive and I fuck her when I feel I want to, always when we are alone. Otherwise what kind of submissive she will be if I have to ask permission every time I want to touch her or fuck her.

I remarked to her that the dress was too long and she has to shorten it so that when she bends down it lifts and expose her butt plug. She thought that I was asking too much for now, and perhaps she will do it when she gets more used to being pantyless in public.

Some naked fun in public

We spent some of the following Saturdays driving in the countryside looking for secluded areas where I would ask grandmum to take off her dress and walk around fully naked.

At first, she was reluctantly being naked in public but being the only person around she started getting confident of being naked. Once I remember that we were walking along a river and there were some people on the opposite side. I thought she was going to ask me to hand her the dress to put it on, but she just asked me if from that far they could make any details of her naked features. I observed that they are so far that we cannot make any distinction of their features and likewise they would not be able to make the distinction of our features.

I asked her how she had such an even tan on her body and not a sign of a bikini line. She took my hands in hers and told me that one day she will invite me to a place she frequents where they have a large pool and nudity is obligatory. I told her I was a bit puzzled that she is naked at this club and many people see her, and she was worried that people see her naked butt in public. She replied that it is a relaxing atmosphere and I can get to see other people naked, while in public it would be only her that would be showing her lady parts, and that makes her embarrassed.

The more naked walks she made the more she became daring and instead of going to secluded areas in the countryside, we started visiting parks. She would wear an oversized t-shirt and a skirt and then she would take the skirt off and walk in just the t-shirt which barely covered her crotch. For sure the vibrator’s antenna was quite conspicuous dangling from her vagina even when she was standing up straight. A slight gust of wind, a gesture of lifting her arm, or bending down would expose her nakedness. I loved teasing her and would rub her conspicuous clitoris. She used to moan with pleasure and begged me several times to stop as if she would reach a certain point she would want me to finish her off by fucking her. I refer to her conspicuous clitoris because although she did not have a large clitoris, it was big enough that when she stands and the inner labia is tucked inside nicely her outer labia, the clitoris always peeps out of there.

There were a few times where she would ask me to drive and she sat next to me naked while I drove in the streets on the outskirts of our town. We heard lots of honking of the horns from truck drivers as they sit at a higher level than a car driver and can see the inside of the car better. I guess that many saw her naked pussy from up there and we used to laugh hearing the remarks they passed at her.

We experimented with visiting museums; art galleries and other exhibitions. For such locations, she wore a dress she made purposely herself that opens from the front and quickly fasten with Velcro tape instead of buttons. When she felt like it, which was often, she would ask me to walk a few paces forward and turn around and watch her. She seemed to enjoy unfastening the Velcro tape and open the front of her dress to flash her fully naked body.

I told her several times that she was risking being caught, and if she likes other people to catch her naked, she should invite some of her friends at home and welcome them naked. She laughed and said that she will think about the idea. She never did, except for once, when I went and found a lady friend of hers also naked. That time grandmum did not greet me naked on her knees by the door. I told her that she was a naughty disobedient girl and the first opportunity I would put her across my knees and spank her bottom. It seems that those words excited her as she said that she would be a naughtier girl in the future to receive the punishment. Her friend was shocked and embarrassed when I walked in on them being both naked and she soon found some excuse and left us alone in the house. I later learned that she was one of grandmum’s friends from the nudist club.

All our outdoor adventures would end up making passionate sex when we were back home. Once she asked me why I devote lots of time to fuck her instead of being with someone of my age. I replied that at her age her periods stopped and I can make sex more relaxed as I need not worry if I will pour my cum inside her or pull out just before I shoot. With her, the decision is easy, I just pour my load inside her. When I fuck my girlfriend I have to make sure that she has been taking the contraceptive pill and I still would be afraid to risk it and pull out and doubting if some precum might have escaped inside her. For such sex, I prefer raisins to grapes, it is safer.

In these months grandmum managed to upgrade to the 4th largest butt plug. When she happily announced it to me, I reminded her how sceptical she was the first time she saw the set. I told her if she realises that the grith of 3rd largest butt plug is more than the grith of my penis and now that she upgraded the 4th largest I can ass fuck her without worrying that I may hurt her when penetrating her. I asked her if she likes being fucked in her arse hole. She said that she never tried it before but to please me she would give it a try. She then asked me if I reached my goal regarding her arse hole and if she can stop upgrading to the next butt plug. I confirmed that the goal was reached and that she may keep wearing that one to keep her hole that wide, however, if she wanted to have a wine bottle up in there she had to work to the 5th grade.

Sister

Once, my sister and I were having a chat while watching a concert on TV in aid of charity. Various subjects came up and somehow the subject of submissiveness popped up just by chance. It must be that it was the few glasses of wine I drank that was talking as I confessed to my sister that grandmum was my naked submissive girl.

My sister told me not to tell her any fairy tales and I dared her that if what I told her was true she too must submit to me and be my naked slave girl and if I was not telling her the truth I would be her naked slave boy.

Knowing I was going to win the dare, one day during that week I went to the town centre to the sex shop and bought another vibrator with remote control. To make sure that the remote would only control that particular vibrator and not also the vibrator I bought for grandmum, I bought a different make.

Before the weekend arrived, I phoned grandmum and told her what had happened and apologised to her for not keeping our secret and informed my sister about her being my naked slave. I told her that the following Saturday my sister will accompany me and I wanted her to greet us naked as she normally does when I visit her. I told her that I want my sister to know that you are truly my obedient naked slave and thus I will win a dare and she would also become my naked slave girl. Grandmum told me in a humorous tone that she was going to get jealous as she was going to have some competition.

On Saturday morning my sister informed mum that she was accompanying me to pay a visit to grandmum. Mum was thrilled with joy, knowing that we were spending some time with her mother.

On the way to grandmum, I teased my sister telling her that from now onwards she does not need any panties and she should throw away all her panties as being my naked slave girl, I will not allow her to wear panties at home or in public. Laughingly she replied that perhaps it may be me who would sacrifice not wearing any underwear.

When we reached the town centre I informed my sister that I was going to phone grandmum and tell her that we would soon be there.

When we arrived at grandmum’s house, we rang the doorbell and seconds later the door opened ajar. I told my sister to enter first and not to open the door wider as grandmum would be naked and she would not like any passers-by to see her in that state. My sister giggled and told me “As if grandmum is naked.”

As my sister saw grandmum behind the door, the smirk on her face vanished and her jaw dropped to the floor with disbelief. Then I entered and closed the door behind me and grandmum asked me if I wanted her to give me the usual blowjob as greetings. I saw my sister’s face scarlet red and she did not hold back showing deep embarrassment. She remarked that she wanted the ground to open and swallow her. Jokingly I told her that before the ground would swallow her, she has to strip naked so I will not miss the winning of our dare.

To look credible to my sister, I informed grandmum about the dare my sister and I made and that now she is supposed to get naked and become my naked slave. My sister started complaining and bringing up excuses to avoid pay her debts of the dare. I gestured to grandmum and she immediately understood that I needed her help to get my sister naked. She went and hugged my sister and calming her down and painting her a picture that being naked is not such a big thing. She also offered my sister to help her remove her clothes. My sister resisted a little bit but let grandmum remove every item of clothing she had on her. I was glad to notice that my sister was fully shaved.

I told my sister that I bought her a special present as I knew that I was going to win the dare. Then I presented her with a remote control vibrator and invited her to insert it into her vagina. She was reluctant but grandmum encouraged her and went to fetch her remote control vibrator. Grandmum showed my sister the vibrator and inserted it into her vagina and invited my sister to insert hers into her vagina, which my sister half-heartedly did.

Grandmum presented me with her remote control and told me to take control of her orgasm. I could see my sister’s face showing different emotions and when I pressed the button on her remote vibrator, she screamed and put her hands on her crutch. Grandmum and I laughed. I assured my sister that the scream was as she did not know what to expect and now that she knows I was going to experiment on her the various levels of the remote control. She begged me to go slowly as the sensation was so intense that a few more moments at that level she would surely orgasm.

Grandmum, in a stammering voice, as I had her vibrator on high intensity, asked my sister how she feels with a live vibrator inside her. My sister just bit her lower lip and only managed to extract a sound of pleasure.
