Warning: This story references face farting and humiliation.

Daisy chuckled, 'Well, truth or dare? Hurry up, The Sack will be here soon.' There's an air of minx anticipation in her voice as she mentioned The Sack, and as she did so the two other girls began to grow sweaty, despite the mild night air, their stomachs churning softly and their skulls becoming somehow lighter with excitement. In the tent there was a stale funk that had developed over time. It was no surprise, considering that they were in a tight, confined space and hadn't washed that night, but nevertheless it made it seem as if it was much warmer than it actually was.

'Truth,' Kate says, biting her lip and squashing her face into a tight, mischievous grimace. There was a moment of silence as Daisy stroked her chin and watched the shadow of the leaves stretch across the ceiling of the tent.

'Okay, I have a good one', Daisy finally spoke, kicking out her legs, 'What's the grossest thing you've ever done to somebody without them knowing it was you.'

Kate licked her lips, 'well, there this one guy at school. Well, he's moved away now, but I remember he used to be one of those weirdos that sit in the corner and stare at the floor. Anyway, somebody dared me to ruin his lunch when he wasn't looking. Luckily for me he used to leave his lunch on the table when he went to the toilet, so all I had to do was wait until he left to sneakily do the deed. Anyway, he went, and I decided to be a real bitch and taint his sandwich, so I open it up, and burped loudly into his sandwich, the kind that leaves bits of your lunch behind as well as chunks of spital.  I closed it and rushed back to my seat. We watched him eat a bite before he began to choke. He rushed out of the room then, probably to throw up. We didn't even manage to hold in our laughter until he had gone, so he knew one of us had done it. We used to call him Burp Muncher from that day on.'

'Oh my god, that's sick', Daisy said, holding her mouth as she giggled loudly, 'I didn't expect it to be that gross. You're one nasty girl'.

Kate slapped Daisy's shoulder softly, 'Shut up, bitch. You're one to talk'.

The three then begun to relax in silence, listening to the sound of the trees, although even that couldn't calm them. There was just too much resting anticipation for any of them to actually contemplate anything other than The Sack, which would soon be theirs to use. They would have access to it all evening and night, unfortunately for Sack Boy.

Out of nowhere, a muffled low ripple vibrated against the floor. Kate and Daisy stared at each other, eyes wide, before looking over at Olivia, who was biting her lips and smirking. Then the raw smell of expired cabbage filled the air, bitter, thick with putrid rot. Daisy held her nose as her face reddened, and Kate began wafting the air as she screwed her face into a grimace of mixed humour and disgust. Olivia was now giggling to herself, wafting her fart around the tent, sniffing the air and exhaling happily as the stink grew stale in the thick atmosphere of their various combined smells.

'Jesus Christ, that's nasty', Daisy moaned, stifling a huge grin, 'You're supposed to save them for the sack. They'll be here any minute now, can't you just hold them in, Olivia?'

'Sorry', Olivia leaned backwards, 'I couldn't hold that one in. I still have plenty more for him to deal with. Can I use him first? I don't think I can hold in all my gas for much longer. I'm bloated with farts.'

Kate smiled, stopped wafting the air, and patted Olivia on the back, 'We'll let you go first. It'll let us build up our gas for when it's our turn. Also, we don't want to deal with any of your nasty veggie farts. Honestly, Olivia, that one was so thick I think I can swim through it. I can feel it in the air, like it has weight, you smelly bitch.'

'Ok, that's enough, it was bad, sure, but'-

Olivia, who was rubbing her belly as her gaze was set upon the floor, was suddenly interrupted by the sound of heavy rustling in the background. For some considerable amount of time nothing followed, but after what seemed like minutes, the rustling began once again, and behind it a low moan. At first it sounded like the wind, but after some time it became clear that what they heard was a muffled human voice.

The three girls smiled at each other, and sat waiting silently, their legs stretched out as the sound grew closer. All of a sudden, several heaving footsteps could be heard, as well as a squeaking noise that held some weight to it. Then the outside of the tent gave birth to three silhouettes, one of which gave a soft chuckle as it's shadowy outline tapped against the fabric of the tent.

Daisy and Kate zipped the tent open and stood back as the three camp leaders, each of them almost identical to each other with their strong, pretty faces and their neat blonde ponytails.

'Hey girls, the sack's here. Don't hold back tonight, he was a real loser in the tournaments today. At least now he'll have some use.'

Olivia sat holding her stomach, her face wrapped up in a painful grimace. One of the camp leaders looked at her and smiled, before the other two grunted as they removed the sack from the cart and dragged it into the centre of the tent. Something inside moaned as it slid against the floor, the sleeping bag that held it in place moving slightly with his struggling movements.

'I wish I was the one using him', one of the Blonde leaders said, 'those beans today really did a number on me.'

'Don't worry, these girls won first place but we'll get plenty of time with him tomorrow,' one of the other girls said, twirling her ponytail with her hand and scratching the hem of her cargo shorts, 'he ain't leaving that sack for a long time. Anyway, you girls have fun.'

Kate and Daisy thanked the camp leaders, who left the place hurriedly, one of them skipping upon the foliage below as their silhouettes melted away.

Olivia's belly rumbled as she rushed, almost ferociously, towards the bag. With quick, rushed movements, she entered the bag, stretched her bare feet out towards the face of the guy inside, and then quickly zipped the sack around her.

As soon as the bag was tight against her, Olivia released a deep, low rumbling fart, which quickly filled the entire sack. It was a brassy flapping fart which was muffled by the thick material of the sleeping bag. Olivia, who had pushed hard, released an almost orgasmic sigh of relief before she laid back, the guy inside the sack beginning to scream sharply against whatever gag held his mouth. He clearly wanted to get out, crying out in an high pitched pig like squeal as his nasal cavity was invaded by that nasty, wretched fart. The camp leaders giggled to themselves as they continued down the path, so clearly it was loud enough for them to hear it.

'Jesus, Olivia, that must have woke up the entire camp. Did you hear his reaction? It must absolutely reek down there.' Kate said, chuckling as she looked towards Daisy, who was still clutching her sides as she laughed loudly. As she continued to laugh, the guy's protests became pained whimpers.

'How's that smell, huh?' Olivia said, shifting around in the sack, 'I bet it stinks, doesn't it, loser? Too bad for that you're not going anywhere. I hope you understand we all have gas and you're going to be dealing with it, it's what you get for being a pathetic excuse of a man. We're going to make it suck big time, trust me.'

And with that, Olivia raised herself in the sack, released a sharp toot, and then collapsed again, chuckling as the guy inside moaned, his breath invaded by yet enough veggie fart. The issue was, for him, that there was nowhere for the smell to go, and since Olivia had made such a spectacular display of flatulence, he was going to suffer through that pure cloud of revolting butt stench for a long time. Olivia knew this as she wriggled her bum in the sack and pressed her sweaty feet into the flesh of her sniffer's face.

'So, Olivia, how bad do you think it smells down there?' Kate asked, smiling, pulling her fringe back and turning her head to one side as she tapped her leg in the air.

'Really bad, that first fart was fucking repulsive, and he's still whimpering, can you hear that? Oh my god, that's hilarious. I think the smell down there is making him sick, but, of course, it's going to get much, much worse for him. Speaking of smell, I gotta fart again.'

Olivia lifted herself in the sack as the sniffer began to plead through his gag. It was no use, Olivia turned to the side, chuckling to herself, as she waited for the brewing fart to echo underneath her. Kate had her ear turned to the bag, and Daisy watched  for it's inevitable struggles.

Olivia with one hand brushed her brunette fringe away from her face, lifted herself even higher, and then audibly pushed, her face screwed up in effort. In the sack there was a loud flatulent explosion followed by a sharp ripple which echoed within the enclosed space, before Olivia lowered herself, her smile stretching out across her face as the slave underneath yelled something and wept in high pitched convulsions which were obstructed as Olivia pressed her dirty feet hard against it's face once more.

'It's only been five minutes', Olivia remarked, 'and I've already farted three times. My belly still has plenty more. Do you think we can replace the entire air inside with farts? Either way, he's not going to have a great time tonight and tomorrow, I can tell you that. It's like he's in an enclosed sauna of farts without ventilation.'

The three then began to relax and speak about various topics: guys, gossip, the latest shows. Every so often a rippling sound vibrated below the sheets and the slave would cry out. Each time this happened, the girls would laugh, and Olivia would make some disparaging remark towards Sack Boy.

It was when they were talking about the latest phones that the sheets underneath Olivia rustled quietly and a smirk quickly stretched out upon her face. Kate and Daisy looked towards her when suddenly the slave underneath began to pant and convulse. He squirmed inside, but Olivia kept her position with the same smirk pressed into her expression.

'Silent but deadly', Olivia said, offering a full explanation as to why the Sack Boy cried out so much. Deadly was an understatement. It must've smelled worse than anything, because the slave was kicking and gagging, almost choking on the air inside. Olivia showed no mercy and soon their conversations continued, the audible suffering of the slave inside merely an ambient backdrop.

Olivia finally sighed and sat up, 'I think it's one of you guy's turn. I'll save the rest of my farts for later. I'm sure he'll look forward to smelling me again, which he will.'

The two girls discussed it as Olivia wriggled her toes across her slave's face, feeling the smoothness of his skin rub underneath her. Soon enough, they had decided, and Olivia leapt out of the sack, only to close it before any of the fart air inside could be released.

Kate, soon as she peeled the sheets away, slid inside and zipped them shut around her. She was heavier, and her feet larger, and inside she realized how hot Olivia's fart's had made the air inside. It really was like a sauna, and it was only about to get worse for sack boy.

'It's really warm in here, Olivia, you're ass is like a volcano. Jesus, I can actually feel the warmth of your farts.'

Olivia giggled and crossed her legs, 'that's what beans does to me.'

'Oh, don't worry', Kate said, shifting her weight around in the sack, 'it has a similar affect on me. Sack Boy is going to understand that real soon. Isn't that right?'

Kate wasn't kidding, as soon she felt within the depths of her bowels a build up of gas which expanded inside of her. Her stomach gave an audible rumble, which was so loud the girls giggled at it. Sack Boy must've heard it too, because he began to struggle, but Kate pressed her weight down further, crushing him beneath her as he full body laid across his own, her dirty feet rested against his face.

'Oh sack boy, these beans are really doing a number on me. You've got your work cut out for you with this one. Just remember, you're here all night, and this is only the beginning. Anyway, are you ready? I'm about to cut the cheese.'

The guy began to plead through his gags for release, struggling in his bounds as the idea of smelling another fart was hell. Olivia had already transformed his breathing space into a vile fart smog, every second was a painful inhalation of a girl's intestinal gases. He knew it was no use, these girl's knew his worth, and they would be showing him how little they respect a loser such as himself.

Olivia tensed and a fluttering, deep fart blew hard against the walls of the sleeping bag, an hot airy fart which blasted loudly, filling the sack with foul air which immediately caused the slave inside to cough and splutter. He tried to move away from the smell inside, but there was nowhere to go, and as such he was forced to remain in the cloud of pure, potent fart.

'Hey, hey, fart sniffer, stop fucking moving I am about to rip another fart so get used to that one it's about to get much worse.'

Kate pushed up her hips and allowed a squeaky, long toot to escape the confines of her volatile anus. This only added to sack boy's efforts, who yelled something into his gag that sounded like the squeal of a pig. Kate begun to tire of this, and so she pressed herself into him so that he was crushed against the floor. He turned a little from side to side but quickly realized that he was going nowhere.  He just laid there and waited, and Kate soon delivered.

Kate cut a deep, moist, thick fart which baked into the already rank air of the sack and pressed against the confines of the walls inside as it expanded fully. Like an oven, the entire sack was filled with the heat of the fart, and the slave beneath began to openly weep and gag at the same time, his choking interrupted by high pitched cries. Then, only a moment later, an even bigger, brassier fart was let out inside the sack, like an explosion of rancid air. Kate laughed as she felt her feet rub up against his tears, and rubbed her ass into her slave as the utter stench overwhelmed him.

'This fucking loser is crying', Kate said, 'What a pussy. It's not even bed time yet and he's crying. He really has no stamina.'

'That doesn't matter', Daisy said, 'he's staying down there regardless.'

'Oh for sure', Kate said, 'the fact that he's crying is all the more reason to continue cutting the cheese in his breathing space. He's pathetic.'

After a while, Kate shifted herself inside and smiled, 'Another fart, loser. Get ready to breath in what I've baked for you. This one feels big.'

It was big. A high, spluttering, almost wet fart vibrated out of Kate's arse and echoed inside the sack. It lasted for what seemed like an eternity. It was a comical, bubbly sound, so loud that Daisy and Olivia were reduced to tears as the fart ended in a long, squeaky ripple of air which was released above the background ambiance of desperate, croaking screams from Sack Boy, whose flowing tears rubbed into Kate's toes.

'Jesus Kate, that sounded foul', Daisy said, screwing her face up in disgust, 'Are you sure you didn't shit with yourself with that one? It sounded wet.'

Kate pressed her finger against her chin, 'Honestly? I'm not sure. I mean, I know it will smell like shit down there, and that wet fart especially would smell really bad. It might smell like I shit myself, but I don't think I did. Still, I know what you mean, I think I would rather die than be trapped in the remnants of that fart like Sack Boy is. Still, he's breathing it in, so I'm happy. It's not going to go away for him, and I think he knows that.'

Olivia shifted onto her stomach, kicking her legs up in the air, 'At least we know one thing. That bag is sealed really good. I can't smell that fart, and I know Kate, that fart she just ripped would usually force us to vacate the tent, if not the entire camp. Sack Boy must be suffering really badly down there.'

'Good', Kate replied, 'he should suffer, he's a fart sniffer weather he likes it or not.'

The girls mumbled in agreement.

'Anyway, when is it my turn?' Daisy asked, 'I have a lot of farts in my belly and I really can't wait any longer to make him smell them. I don't want to have to stink the entire tent out, so can you let me use the sack?'

'Hang on', Kate said, 'I just need to let another one go. It's trapped and I'm trying to let it loose. It's gonna' be a big one and I don't want him to miss it.'

'You better hurry', Daisy said, 'or I'll have to make Olivia smell them.'

'You fucking dare', Olivia said, a flash of fear drowning out her expression as the other girls laughed.

A minute later, Kate's belly made a huge announcement via a large rumble: she was going to fart.

'Here it is', Kate said, lifting herself off the slave, who began once again to plead to her. It was, as before, useless, and Kate merely grinned as his begs made their way through the thick material of the sleeping bag.

There was a moment of silence before the sound of rippling ass echoed throughout the tent, originating from the sack inside. It was a long, deep fart which ended in a brief high pitched blast which sounded almost squishy. As it exited her bottom Kate sighed and laid back, smiling as Sack Boy reacted in disgust to the smell of her fart.

'That was pretty bad', Daisy said, 'I'll give him a minute or two to endure that one before I begin tormenting him. It'll give my farts extra time to build up.

'Good idea', Kate said, rubbing her warm feet hard into Sack Boy's face, who moaned in pain, 'Let the fart air inside a bit. When he's sniffed it for a bit longer, I'll let you in.

When Daisy finally did get in, she ensured the sack was wrapped neatly around her, tight as to trap inside the various intestinal smells for Sack Boy to endure. Her feet shot in and crashed against Sack Boy's face, who moaned as the dull pain drilled through him. Daisy had done this purposefully, and so begun to laugh, a second before a sharp, girly fart escaped her bottom and coiled inside the stale air of the bag. She laughed even more, which caused her feet to crush against the flesh of her victim, who screamed from both the pain and the tang of her fart.

Before anybody could say anything, another series of cracking farts could be heard inside the bag, like a chain reaction of smelly, gritty toots which escaped one after another. As the ripping continued, Daisy laughed so hard her face turned red. In fact, the fart lasted so long that even Kate had begun to laugh loudly. It was comical, and the slave was crying underneath the sound of girly tooting. The fart ended with a loud, airy blast which was so loud it left an echo behind, much to the amusement of the girls, who begun to clap for Daisy for what seemed to be the longest trailing fart they had ever heard. It must've stunk, anyway, because the slave had once again begun to weep.

'Finished?' Olivia said, and the girls once again laughed.

'Don't worry', Daisy said, looking at the sack, 'I have plenty more farts for your nose to gobble up.' The slave begged once more but was met with a cracking kick to the cheek which clapped against her dirty feet.

Daisy wasn't wrong. Once she was finished with her slave over half an hour later, she must've farted more than both Kate and Olivia. Usually, the farts were smaller and airier, but still they were farts and they smelled like farts, at least according to the constant moans of Sack Boy.

'Ok, final toot for you, Slave', Daisy said, pushing an airy SBD out of her ass. Olivia and Kate were only made aware that a fart occurred after the slave begun to struggle and push at the walls.

'Right', Daisy said, zipping the bag up to leave the loser inside to breath in the accumulated stale farts, 'what now?

'I'm quite tired', Kate said, 'Why don't we get supper and then call it a night?'

'Ok, but who is sleeping in the sack?' Olivia asked, hoping her name would be called out.

'All of us. We can squeeze in, and he'll get triple the farts all night. Sound good?' Kate looked towards her two friends.

The girls all agreed giddily, giggling incessantly as they looked towards the sack, smiles plastered to their smooth faces. As the guy inside began to panic at the mere idea of three girls trumping merrily inside his breathing space, he cried and struggled, but as usual it was no use and the girl's ignored him.

'Olivia, I dare you to smell inside the sack', Daisy said, winking at her.

'Err- Ew. No Way.' Olivia replied, backing away a little.

'No, Olivia, do it. Just a quick smell. I'm curious as to what it smells like', Kate said, kneeling over her.

Olivia rolled her eyes, 'Fine, I'll do it. Just a little smell, through.'

Olivia pressed her nose against the opening of the sack and then let the zip open just a little. As the air inside leaked out she quickly shut the zip and shot backwards, heaving dry air as she wafted at her face.

'Oh my fucking god. That's so fucking nasty. How is he still alive down there?'

Daisy and Kate giggled as they teased Olivia. After a while, they were going through their bags to see if there was anything they would need before Bed. Kate took a swig of water and Daisy threw her bag across the tent as Olivia set her empty gaze on the shadow of the leaves upon the tent ceiling.

'Let's get some oatmeal and apple juice for fart fuel', Kate said, and the girls left the Sack Boy to contemplate the rest of his night, to let him fester in the hell of knowing what he was going to be treated to all night long.

They returned with full bellies. Giggling and pushing at each other they pressed themselves into the sack. It expanded against them, much to Sack Boy's dismay, whose begs were once again ignored beneath the crushing weight of three girls, however petite most of them were. Kate sat in the middle, her butt rubbing against Olivia's belly. Daisy faced Kate, and gave her a wink at they settled into each other. It was tight, yet they managed.

'Your butt is rubbing against me', Olivia moaned.

'Oh shut up', Kate wriggled her hips, 'At least you won't have to smell them. Anyway, good night, I'm turning the light out now.'

As the pure darkness of the wilderness overwhelmed the tent, the girls relaxed. Almost instantly the sounds of the trees blowing in the wind and the crickets in the fields began to dominate the ambiance, and other than an occasional moan from Sack Boy, all was calm.

It was only a minute later when the sound of a fart rippled out of one of their butts. The slave cried out and the girls all giggled shifting about as the fart became his air. A second later, another fart escaped, a manly crude fart which settled into the nose of the slave inside.

The oatmeal was kicking in, and Sack Boy was in for one long, stinky night.
