I said to Ayesha I was going to move near the dividing wall could she stand in front of me with her bag so no one could see, we managed to manoeuvre to the doors as the dividing wall had plexi glass and there was a man sitting the other side, I stood against the door facing forward and Ayesha covered me with her Tote bag that was reasonably wide the eggy smell was not so strong but I was clinging on with dear life to another fart . I reached under my skirt with my right hand and felt around until I had my fingers on my bum crack I could feel the peach knickers wedged tight up it, they felt really moist hoping it was from the sweat , sis don’t laugh but my fanny was very wet and creamy , why I asked already squirting pussy juice into my knickers from the hot stories so wanted all the sexy details . Really Sis if you must but it’s a little embarrassing, think it was the situation anticipation of getting my pussy felt by a cute boy , the hot carriage , the tight knickers wedged up my arse crack and the warmth of the hot farts soaking into the wedged material . Ok I said I would be wet too from the thought of the boys and suppose some warm knickers up my arse too and giggled so how from feeling them did you discover if you had soiled them with poo. I couldn’t Kelly said could just feel how warm and moist they were , I tried getting a finger under the tight wedge cotton to see if I could touch the inside of the knickers were they covered my bum hole see if there was any poo residue , the knickers were really wedged tight in my bum my hand was very restricted as I was pressed up against the door and couldn’t make it obvious I had my hand buried up my skirt . I managed to get my index finger under some of the tight cotton but as I tried pulling the wedged material enough to get my finger in I suddenly started farting as fiddling with the wedge had released some of the pressure of the knickers forced against my bum hole ohhhh it was disgusting my hand got coated it warm fart felt really weird though sis feeling it coming through the moist knickers all hot so I left my finger over the wedge for the whole time the fart came out it was about 65 seconds of air , I could feel my knickers soaking up the fetid gas made me a little wetter is that weird sis , know I said warm knickers wedge up your crack made warmer by a hot airy fart would make me wet . Ok the carriage filled up with rotten eggy gas again I pulled my hand out from under my skirt , Ayesha leant in and whispered Car did you just fart all over your hand I nodded and went red . I managed to look at my finger it did look clean no brown stain . Ayesha leant forward again and said gosh kelly that really does stink is that the last one I said unfortunately no and I really need to check my knicks for stains Ayesha before we get to Green Park. Ayesha dug around in her bag and brough at a small make up mirror with small battery powered lights around the rim , she said if I hold it and you slightly open your legs I think I can hold the mirror under your skirt you can see if you’ve stained your knickers , ok I said she flicked a switch when the mirror was out of site and the rim lit up around the rim I slight parted my legs making sure none of this was visible to the other passengers , I leant forward and said to Ayesha please don’t look its embarrassing she said of course not , she held the mirror so it was angled up my skirt , the light was bright so suddenly my upskirt was illuminated I looked down I could see my knickered covered pussy gosh it was sopping wet sis , I parted my legs a little more to get a look at the tight material up my arse crack I got a good eyeful of wedged knickers up my arse between my legs the whole of the underneath of my knickers were extremely damp the bit covering my pussy was wet and soapy , the bit up my arse was just damp , Ayesha glanced down and then looked up quickly she leant forward and said sorry Kelly for some reason had to look down it was a reaction , she said at least they are clean she whispered but they are very wet and very wedged are they uncomfortable , I whispered back to be honest feels kind of nice against me I said all warm and tight I said ohh dear I think I need to fart again its hurting my belly , I reached round and put my hand back up my skirt Ayesha leaned forward and said what are you doing Kelly , I said kind of kinky feeling them come out is that weird I whispered have you ever felt one come out Ayesha , she said yes one time when wearing tight jeans and knickers I needed to fart I was in my bedroom getting ready to get out couldn’t resist it but my hand on my arse crack and farted on my hand through my jeans was kind of kinky I did smell my fingers also as I do like the smell of my own farts she said , it’s the first time for me I said but it feels very kinky especially on a packed train in a short skirt farting and no one knows were they the stink is coming from . Sorry sis if I’m grossing you out, I Said carry on imagining it was my hand up my sister’s skirt.
I know it’s a little disgusting, but I had to do it again, was very thrilling doing this on a train in public with the air filled with my arse stink , I really was aroused for some reason Sis , you know when it super exciting and new kinky and disgusting all at the same time , might as well enjoy my predicament my hand was under my skirt and I touched the wedged material between my bum cheeks , the material was very warm and damp from my own sweat and the heat of the carriage I didn’t touch my fanny though would save that thrill for the boy , the tight wedged cotton between my bum cheeks felt naughty , my bum cheeks were very warm also , I sort of pressed my fingers into my arse crack over the wedged knickers and slowly let my bum hole open suddenly the warm knickers got warmer as hot fart air soaked into them , my fingers felt the hot knicker filtered gas ohh gosh my poor little knickers sis it was a lot of gas they were filtering the carriage started to fill up with that lovely eggy fart smell people were really moaning now but so far no suspicion on me , the fart just kept coming through my knickers onto my fingers , Ayesha leaned forward and told me to try and hold it as it was too much in one go .
I was still full of gas sis so pinched my bum hole and felt the warm flown in my knickers stop. I reluctantly removed my had from my skirt and started talking to Ayesha, was really nipping my Bum hole, and using the knicker wedge to brace against. Ayesha asked me in my ear why I am always so gassy , she said she mostly farted in the morning or after evening dinner , the occasional couple in the day but since she has known me I was like constantly farting when she was with me I said I don’t know really must be an irritable bowel thing it could be a pain a lot of visits to the toilet at School , stained knickers my mum was always moaning about the skid marks in most of my knickers and how hard it was to get the marks out and everywhere I am usually smells of rotten eggs . You can say that again Ayesha said lucky I’m a good mate, she did say that today’s ones were the worst ones she had smelt but it might be the packed train carriage. I asked Kelly so what does it feel like felling a fart through your knickers does it make your fingers smell , Kelly said that she wanted to smell them after taking her hand out of her skirt but it would have been too obvious , she said haven’t you felt any of your farts as they come out Sis , I had hundreds of times always imagining I was feeling another girls bum as the hot farts rushed through my tight knickers , but said no never done it Kelly she said if you want to try it I really need to fart badly again Kelly said I know it might sound weird but do you want to feel a fart coming through my knickers if you haven’t tried it before , really I said a bit to eagerly yes were sisters and its nothing sexual just feel one out of my bum and how it superheats my knickers then you will know what I’m talking about in my train story . Ok then I tried to sound a little disgusted but really couldn’t wait to feel her bum through her knickers the fart as well, well that would be like heaven.
Ok sis she said , Kelly bent over and stuck her knickered arse out , he knickers were stretched tight over her bum crack , I touched her knickers that covered her bum cheek , Kelly got her hand and guided my fingers to were her knickers covered her bum crack and arsehole , gosh the knickers were all warm and swampy and sexy , I think all the constant farting had given Kelly a sweaty bum . Kelly made sure my fingers were over her Bum hole but not near the part were her wet pussy was soaking into the knickers
