Ok I said what did she look like or more accurately what did her arse look like lol, well the trousers fit her bum like a second skin but were riding up her arse crack every time she bent slightly and her knickers all the lines were very visible high cut and looked very tight as you know I am not a close friend of Clarissa but we often chatted , I was outside the headteacher office when she came out into the corridor , I said HI Clarissa what was that about , she said Mrs Clarke had pulled her in and warned her that coming in dressed as I was is not appropriate and that I would be suspended if I came in dressed like this again , she said it was to much of a distraction for the boys. Clarissa said to me well that’s why I wore these trousers not for comfort but for the boys and giggled she then said quietly that the tight trousers and knickers were making her very gassy and nearly farted in Mrs Clarkes office as soon as she finished the sentence an airy leaking gas noise came out of Clarissa’s arse ohhhh sorry she said that just came out I am so full of farts today she said , I said don’t worry I am a very gassy girl and getting through a college day with out releasing any in class is a challenge most days . She said that she wasn’t that gassy other than mornings when she farted an average of 10 times whilst getting ready in her bedroom then a few more times when doing her number 2 before leaving for college, she went onto say that this was like this morning had emptied herself of gas and felt no need to fart, she had done this in her pyjamas and bedtime knickers. It was only once she had showered and I had put on my get a boy a little too tight knickers and tight trousers that I started feeling gassy again , I must of fart 20 times on the walk to school they are all just like hot air and they stink no noise just like a squirt of hot air in my knickers then the foul eggy smell , just strange that as soon as I put on the tight knickers and trousers I needed to constantly fart , its only material how can it do that now I have to struggle though college needing to fart all day and it stinks just one in class and I will be so embarrassed , then she said she had visited the toilet already 3 times to fart and she had checked the inside of the knickers as the farts were so hot in them it felt like they would stain them brown other than a slight brown mark from the sheer volume of gas I had already released they were reasonably clean ,I said perhaps it’s your bum punishing your knicker’s for being to tight and giggled she said yes it feel like that my bum is complaining that the tight knicks are restricting it too much . Ok I said all you can do is cling onto them and keep asking to use the toilet and push them into the toilet pan until you feel empty enough to hold them to the next visit, that what I do every day, probably get away with 3 visits in the morning 3 in the afternoon and 2 or three lunchtimes. Clarissa said ok thanks for the advice see you in English literature class and she headed to the toilet, gosh did she had a lovely bum if only I could own that bum for a week I would get so many boys her panties did look very tight the sight of her walking down the corridor was a little on the rude side I have never gotten away with a knicker line display so obvious as Clarissa’s bum was displaying today it was rude to say the least like she was walking down the hallway in just her tight panties with tight black trouser cloth over the top , you could see the complete outline even the lace pattern through the trousers . I was in English lit before Clarissa as you know sis I’m probably the gassiest girl we all know so I had farted myself as empty as I could in the loo before class, in the loo I had seen Clarissa, I was washing my hand after sitting on the pan and pushing out a lot of gas , the toilet smelled of eggy sulphur from my arse , she came in through the door in a hurry and I was washing my hands as she walked along farts were leaking out of her arse in little airy intervals as they filtered out of her knickers and trousers there was a trail of heavy cabbage odour that easily overshadowed my fart smell Clarissa’s fart after fart as she tried to get to the toilet cubicle ohh gosh Clarissa are you ok she said not really just cant stop farting I might go home , I said you will be suspended if you do , I know she said but my knickers are on fire with farts and I’m not sure can get through English lit without farting , she said this as she opened the cubicle door and went in , I shouted out to take her knickers and trousers of and sit on the pan and try and push out as much as possible you will get more out unrestricted . Sis just out of curiosity I had to wait outside the cubicle just to here her farting and moaning not sure why just had to, just curious to see how many time she farted . I heard the farts still leaking out as she pulled her trousers done the stink was foul and getting stronger I heard her struggling with the tight trousers and then the rasp of her knickers being pulled down then a sigh of relief as he arse was allowed to fart unrestricted , I nearly giggled hot whooshing desperate gas filled the toiled pan and it just kept coming for like 4 minutes of solid farts into the pan , Clarissa sighing with relief then then a pause as she was probably checking the inside of her knickers for soiling something I always do when farting in the toilet , then the knickers coming up , I left at that stage and went to English lit I was one of the first to get there , no sign of Clarissa she must of gone home , but just before the class started she came in to the class in a hurry but looked distressed she always sat next to me in English lit we were really just English lit friends and nothing more , She was usually very full of herself and could be little annoying but today she was very sheepish and looking to me for help , she whispered in my ear that she could not stop farting and had done the toilet thing just before coming to class and waited until the last minute to empty herself as much as she could but the farts were replacing themselves as quick as I could push them out dam these too tight knickers she moaned quietly to me .
