MY KNICKERS AND FART FETISH PART 35

 

I found the story of her and her sister erotic I could see Sandy had enjoyed it also, Petra was hungrily sniffing the gas leaking out of my bum, I said to her tell us another story of you and your sister, what was the rudest thing you experienced with her. She said that she had many times with her sister that  were very erotic until they got to a certain age when her sister would have cottoned on that she was perving  out on her bum, farts and knickers. It was when her parents took them camping they were around 15 at the time  , Kelly had been suffering from constipation for nearly 7 days it was another thing she suffered from as well as being super gassy , I think her insides were wired a little wrong as she is still very gassy now they were older .

 

When she was constipated it usually lasted for about 3 days and she would fart a lot , I think it was the volume of poo inside her causing really smell farts , this time she had not gone for a number 2 for nearly a week , her belly was visibly bloated and even my parents were moaning as the journey to  Dorset she kept letting farts go the whole 2 hours in the car and they really stunk , she had on some black legging shorts tight fitting and some nylon white knickers underneath , my sister always had very visible panty lines in most thing she wore , she done it as she knew most boys liked it and she also loved wearing tight fitting knickers under everything , our mum used to comment that he knickers lines were awful  and to wear loser clothes but she didn’t listen as nothing changed , I was in the back of the car with her and she would keep lifting her bum of the seat and squirting farts out of the shorts and knickers I made sure I wore clothes that wouldn’t show that my pussy was very wet, this journey I was soaked through from the hot fart smell that was renewed from my sisters arse every 2 to 3 minutes and that she kept digging her fingers in her bum to pull the shorts and knickers out of her crack .

 It was the first day our parents told us to check out the area whilst they unpacked the tent and equipment , me and Kelly were wearing T Shirts and shorts , as usual Kelly’s shorts were always a little snug around her bum , always thinking about impressing a boy etc , our mum had commented on the visible panty line she always seem to have whatever she wore our mum said it was rude to walk around in such tight clothing at her age Kelly just sighed and carried on regardless little did she know it turned on her sister just as much as any boy . We decided to follow the nature path that lead to the cliffs above it was around 5 miles long, every 2 or 3 minutes Kelly was letting off really ripe farts, I was quietly enjoying the rotten smell as they left her bum and to be honest the site of her bum in the shorts, loved hearing and smelling the farts come out of the pert bum that was encased in shorts and knickers. We got 15 minutes along the path when Kelly announced she really needed a poo, I said shall we go back to the camp site, she said she would never make it let rip a long airy fart and told me to come into the woods were no one would see them, I said why she said hurry as we run into the woods she was releasing lots of tiny exploding farts. We got 200 metres into the woods and she desperately pulled down her shorts , then her knickers as she was squatting a large turd came out of her bum was around 7 inches long it came out followed by a mass of wind , was expecting more but that was the only one.

She pushed but only more farts came out she then got her backpack and took out some handy tissues and wiped her bum. She pulled her knickers and shorts back up. I asked her if we should go back to the camp she said she was ok let’s carry on, the turd had not stopped her farting as before every 1 to 2 minutes another fart came out of her arse. After about a third of a mile she started farting a lot more and said she needed to go again urgently, we done the same thing run a little way into the woods her bum was popping farts in rapid succession, she got to a clearing and yanked her shorts and knickers down in one motion same time squatting a turd shot out of her arse another 7 plus inch one followed a by a tonne off farts. Kelly was moaning that she had been trying to poo for 7 days and nothing would come out, so now why now she said. I asked her if she was empty now , she replied with no I still feel really full she moaned and  stayed squatted she pushed as hard as she could but a lot of really smelly farts exited her arse , I stood near enough to enjoy the cabbage poo smell .

 

She stayed pushing and farting but no more poo came out. She sighed and pulled up her knickers then her shorts, we walked out of the woods to the path we got another 10 minutes along the path when she starting farting again, they were hot little pops one after another ohhh gosh she run off the path into the woods popping farts all the way into the trees I followed behind taking in the sexy odour coming out of her tight shorts. She pulled the shorts down but didn’t get the knickers in the same action as previous, her knickers were a lemon lace Tanga cut very snug round her bottom, farts were still firing through her knickers and before she could pull her knickers down a turd came out of her bum and poked itself into the tight panties, I thought it would come fully out into her knickers but it just poked out restricted by the tight lace. Kelly got her fingers around the knickers elastic and pulled them carefully down making sure she pulled the tight material of the tip of the turd so not to stain the knickers with the head of the turd.

 We still had around 20 minutes before we needed to leave , as she still needed to fart a fair bit and thinking that she would get a brown mark in the knickers , every time she needed to fart she would lay on her bed on her belly lift her skirt up over her bum , put her fingers under the knicker elastic and pull the tight material away from her bum and fart I made sure I was in the right position to see her do this and was super aroused the room stunk of my sisters farts and was erotic seeing her do this to fart .

 

We were both ready and left for the day for school, on this occasion we walked the 15 minute journey together, it was down a quiet road and three times, she looked around to see if anyone else was around, put her right hand up her skirt, pulled her knickers away from her arse and farted , we got to school and parted as we were in different classes I knew what I was going to do tonight I would find the knickers is the dirty washing hamper and sniff them .

When Kelly got home she looked a little down , I asked her if the knicker flashing had gone well with the boy, she said no never flashed them she said she had been full of gas all day and had to hold them in class so the effort of holding her farts in had meant it was too risky to flash her drawers encase she accidentally farted , she had managed to hold them in each class but it meant a brisk walk to the toilets to let them out and on each occasion luckily it  was only her in the toilet but before she could get to the cubicle and get the knickers off she had a desperately   let a series of machine gun farts before she got to the cubicle all in the knickers . This had happened 5 times before her gassy belly had settled, she had gone to the toilet to check her knickers were still clean but they were stained with a clear brown skid mark from all the farting. She had been terrified all day that her knickers would show by accident and someone would see her dirty knickers. I went over to her and playfully lifted her skirt, the knickers were white with a sheer patch that covered her bum crack and there was a really obvious brown skid mark up the back of them I said Kelly they are ruined told you all that farting would ruin them. She went to the bathroom with another pair of plain cotton knickers to change them and put the other pair in the hamper were all the dirty clothes went for washing. Later that night I found them in the hamper and took them to bed with me making sure Kelly had not see me take them I had to wait until she was a sleep , under the covers I put the knickers over my face , the gusset had a thick crust of pussy discharge a lot more than usual , it must of been the excitement my sister had off the prospect off flashing her knickers at the boy she fancied , but the gusset smelled nice like dirty knickers doo , the bum smelled of poo and sweat I sniffed and licked the poo and pussy discharge whilst fingering my own pussy I cum for the first time was lovely , it’s since this day and many more of my sister knickers wrapped round my head and my fingers in my pussy .

I had been getting aroused for awhile around my sister when she farted I knew she was my sister but it was this girly bum releasing farts that smelled really raunchy to me, didn’t have no sexual feelings for my sister but I definitely had sexual feeling for the smell of her very smelly farts and was fascinated by her arse loved everything about it the peachiness of it and the gas that came out of it.

Kelly she said her sisters name was, thought  it was great fun filling up the bedroom with cabbagy farts thinking I was disgusted by them , I would pretend to be disgusted whilst enjoying the whole thing .

 

Petra said that she knew from that day she was only into girls and the farting fetish  , then her sister had pulled on the lace white knickers she was so proud of and had bought from her own money , she thought nothing of me being there as she pulled them over her bum , I think she had bought the wrong size as when she pulled them over her arse they really had trouble containing her bum her cheeks were bulging out the sides , I made a joke that her arse was to fat for her knickers . She said that boys like girls when there knickers fit tightly. She then carried on getting her bags sorted for school in bra and knickers, she was walking around the bedroom just letting farts go in the knickers, she would sort of make a show of bending slightly and sticking her bum out then letting the fart out through the knickers, I said no boys going to fancy you with those farts and told her knickers would smell of farts by the time she went to school. I was clothed and packing my own school bag when she came over and pushed her bum into my face, her knickers already smelled slightly of the farts she had been releasing for the last 10 minutes she pushed her bum back hard and my nose was pushed into the knickers and was against her bum hole she pushed hard and farted all over my face it was a huge smelly fart and I was aroused, she thought she was punishing me by doing this.

 

I said that how disgusting she was farting in my face, the more I looked disgusted the more she would do it, I told her that her knickers reeked of farts and she would stain them brown if she kept farting like she was. She looked round in horror and told me to be honest she bent over so I could see all the fabric that covered her bum , they stretched so tight could see her fanny and her bum hole vaguely through the knickers I told her she was clean , she told me to smell her bum again and be honest do her knickers still smell , think that the fact she had her bum stuck out so much she released a huge fart again right into my face this one was an accident as she stood up and without thinking apologised . I giggled said that her knickers will be ruined before she even got to school.

She said that she was extra gassy today could be the excitement the she was going to be flashing her knickers to the boy, she put on her skirt and the rest of her school uniform.

Sandy said to me are you sure I nodded and warned her again how her hand was going to smell bad etc , she cupped her hand over my shorts were the hissing was coming from , ohh gosh she said that is warm , she giggled and said ohh dear your poor little knickers are getting punished , she then commented how hot my bum felt through the shorts she meant the temperature I’m sure as my bum was very warm as the hissing gas was saturating my knickers with warmth .

 

Petra asked if she could have another go as it felt very sexy and she was feeling aroused this was obvious as she wasn’t holding anything back, she asked me if it was ok if she got on her knees and put her nose on my bum so she could smell the gas as it came out, I said yes but as it was all out in the open, I said to Petra yes but before you do can you fart in my face please.

 

She said you really want me to fart in your face , yes please if you don’t mind , Petra said ok Sandy still had her hand on my bum and my bum was still hissing a steady stream of fart all over her hand .

I said to sandy I would get on my knees, sandy said ok and took her hand off my arse.

 

I got on my knees hissing gas out of my arse all the time the area smelled of bad rotten eggs, Petra stuck her bum out ohh gosh her bum was edible it really was it really was the perfect female bottom it was perfectly round and stuck out , it sort of pouted as it looked like it was straining to burst out of the tight knickers and shorts , they were stretched so tight across it and the way the edge of the knickers poke out of the shorts was crazy sexy . I pushed my nose into the shorts and instantly the raunchy smell of her knickers filled my nose, her bum just smelled ripe sweaty and of dirty knickers also a very strong smell off pussy. She said are you ok sorry my arse probably smells bad it’s a little sweaty I think it the shorts and knickers being a little too tight. I said I thought her bottom smelled very sexy, she pushed back slightly my nose was actually in her arse crack pushed tight against the hot material when I felt her bum hole push out and it let out a loud pop, it was a rich cabbage smell she pushed and another loud pop covered my face, she asked if she should stop I said please carry on and she pushed another loud fart out, she released 5 hot pops over my face rich cabbage and sulphur. She said she still needed to fart but wanted to sniff my farts some more , I rubbed my nose up her arse crack and savoured the smell of dirty knickers that had come back now the fart smell had faded , then she removed her bum from my face and eagerly told me to stand .

 

I stood up and Petra kneeled behind me she stuck her nose eagerly into my bum through the shorts and knickers I could feel her nose as it eagerly sniffed the hissing gas that was leaking out of my arse she was lightly moaning and said that it smelled rotten but raunchy she said the gas was really warm she commented that is was really sexy that the fart was a constant tiny hiss it was like candy hissing though my knickers and shorts I said to Petra you are really into this fetish aren’t you , she said yes she had been into farts and knickers since she was a kid , she had a sister the same age her sister was disgusted by farting and other girls knickers and was totally straight but her sister was always gassy like always . Petra said the first time I knew I had this fetish was when she was getting ready for school her and her sister shared a room they were around 13 and her sister had bought some lacy white knickers with her own money she fancied a guy at school and told me that I could tell mum that she had the knickers, she wanted to flash them at the guy today see if he would notice her. Her sister had a much more developed body than her at 13 ,a peachy bum and decent breasts for a 13 year old , our mum was downstairs so my sister since early that morning had been letting farts go , she was moaning that the dinner we had last night had played havoc with her belly , the farts had smelled like rotten cabbage , she was my sister so was walking around the bedroom in her bra and nothing else , she tended to stick her bum out every time she farted and would fan them at me Petra said .

Petra then said to Sandy your turn at the same time plucking the slight wedge of knicker and booty short out of her full bottom. I thought she was going to push another fart out but she sort of smoothed her hands over her bottom to make sure the shorts covered her pouty bum cheeks and she stood with me, my belly was gradually filling up with wind again but slower than it had earlier to my relief my belly must be settling from the cheese. Sandy got up to the rack and the first squat her knickers instantly wedged up her arse along with some of the loose short material , she plucked them out but it happened on every squat no farts though , me and Petra were basically looking at her arse begging for a fart to escape , on the last rep of her set she stuck her arse back , the knickers and shorts wedged deep in her arse crack , she moaned  and said oooh that’s uncomfortable placed the weight back on the rack , with her bum facing us  both she dug her fingers up her bum crack and slowly pulled her knickers and shorts out , as they came out of her bum crack she released a long airy fart she took her time removing the material and the fart lasted the whole time it took to un-wedge the material from  her bum , when the wedgie was totally out another fart wooshed out and the air although outside was filled with a strong poo odour , she apologised for the smell and the farts and moaned that she was constipated again and hadn’t been able to go for 4 days, that explained why the fart smelled strongly off poo.

 

Then it was my turn to squat I got to the rack, my bum and belly was full to the brim with gas all though it had filled up slower than this morning it was still a lot of air and my already tired little bottom hole was fighting to keep it from coming out, I couldn’t just start farting as soon as I done my first squat it would look a little obvious and wasn’t flirty as Sandy’s and Petra’s farts had been.

 I thought  the only chance I had of not farting hugely on the first squat was pulling my shorts and knickers up a little tighter so the resistance would help my keep my little bum hole shut I grabbed the waist band and pulled them both up together taking care not to wedgie them . I got under the bar and went to lift the bar of the rack when the volume of gas balanced against the resistance of my panties and shorts and the pressure was too much to hold the hot hissing started again , I said sorry girls my belly is too upset I’m full to the brim with gas , I might have to go home as its out of control there was a constant stream off eggy gas hissing out of my knickers and shorts  , Petra said giggling said  is that hissing noise coming from your bottom she said to me . Yes I said isn’t it awful and it really smells. Petra just came out with it can I feel it coming out she asked with a look of extreme excitement I said it will make your hand extremely smelly and let out a nervous laugh , please I want to if it’s ok Petra said . So she walked over and cupped her hand over my shorts where the hissing was coming out my little bum hole, her hand felt nice against my bum  and I could feel my pussy moistening in my gusset . Ohh Petra said that is really warm and then she said it feels so sexy coming out through your tight shorts and knickers , she held her hand there for 5 minutes then she put her hand up to her nose and sighed ohh how sexy she said my hand smells of eggy fart and your hot knickers . I think Petra was so aroused she had lost all of her inhibitions and was just saying what she was thinking , she called Sandy over and said put your hand there she reluctantly removed her own hand but put it straight to her nose and you could hear her inhaling it and sighing quietly .

I went downstairs and had to tell Sandy it was my time of the month that had started early on  the way to her  and that it caused my vagina to get very wet  , Sandy giggled ohh gosh that is very wet I can see , then said do i need to borrow a pair of fresh knickers I said I wouldn’t want to ruin any of her panties with my leaky lady part , we walked into the garden , I couldn’t believe my eyes Petra was in the garden standing by the squat rack with what looked like booty shorts on they were a light red colour , the where so skimpy and tight not only could you see very visible panty line , but the knickers were slightly bigger than the shorts so poke out around the edges they were a pale pink looked very tight. Was a rude vision, the booty shorts clung perfectly to her bum and the vpl was very exciting I was so hoping she would fart in them soon.

I was already filling up with more gas , the volumes of gas was to much and was exhausting my little bottom hole was working overtime to contain it all I didn’t think it was right to just start openly farting and wouldn’t be sexy just farting uncontrollably , Petra said high and her eyes looked briefly at the soapy patch on my crotch then looked at me and said nothing more , my bum was on the verge of releasing a massive fart only my tight knickers were helping hold it back, also soon the hissing would start . I said hello then announced that I had left something in my coat ill pop in grab it and be straight out. I knew I wasn’t going to make it to the toilet an lucky Sandy didn’t follow me buy stayed in the garden , I went into the hallway got my handbag sized air freshener out of my bag and spotted the cupboard that sandy must use for storing her hoover etc , I opened the cupboard stuck my bum into the cupboard and pushed out a massive whooshing fart , it went through my knickers like I was naked it was such a strong woosh of gas the knickers and shorts offered no resistance with me pushing hard . The hallway smelled instantly off egg , the cupboard must of been worse , I shut the cupboard quickly as a bulk of the gas had gone into the cupboard and sprayed in the hallway , I let a small 20 second fart out but sprayed the area as it exited my arse ,  I vision of Sandy’s bum and Petra’s entered my head as the last fart existed my arse an warmed my little knickers I felt more juice squirt into my gusset , was a soapy mess between my legs .

 

I felt extremely turned on even though I had an orgasm earlier, my belly was reasonably empty and my bum hole had no pressure on it for now, I went back to the garden . Sandy said let’s do the squat with ten kilo’s each side to start. Petra said she would go first , she got under the bar and me and Sandy stood behind and admired the very sexy view , when Petra done her first squat the shorts and the knickers rode up her bum so they went into the crack at the bottom but not all of the material only the bit at the bottom of her arse crack . I felt giddy looking at the tight booty shorts and panties stretch to their limit as she poked her arse out . She squatted 6 times on the 7^th squat as her bum poked out at the bottom of the squat , a loud pop exploded from her arse not airy like what come out of mine or Sandy’s arse when we farted a really crisp pop like a bubble popping , Petra gasped and said oops sorry , as we were outside it was a short lived waft of cabbage that was gone by the time we got to sniff it . My arousal was building with anticipation, watching Petra stick her arse out an release a fart through that tight material. We both said ohh that was loud and giggled , Petra replied saying that mostly her farts came out loud they were hardly ever silent and made it awkward when in public . She admitted to fating twice in her gym but was lucky that she and one other girl had been in the gym at the time. She finished her next 2 sets with no more gas , but as she walked away from the rack she squatted slightly and another small pop escaped her bum with a brief cabbage smell and an excuse me .
