Inside a Farting Girl's Ass 03

"Christina …we are conducting more than just an experience of your farts…we are trying to come up with a way of chemical warfare…do you know what I'm talking about?" Christina shook her head as she continued to sip her drink.

"Christina, you have always wanted to help out the world, to do something good for the government, work for us…right?" Captain Parker asked.

"Sure…what can I do?" Christina asked.

"We want to develop flatulence inside of use to be able to use against the enemies of our country, as your handiwork today has proven, you can gas people almost more efficiently than are regular gases, your stomach is just that potent. What do you think?" It took Christina a few moments to realize what they were proposing. Of course, she liked the idea, the ability to get out there and be in the action, she would be able to bring down the baddies like always, and it wouldn't involve having to kick anyone's ass, it'd just required her to let one rip.

"Awesome….oh….oh no." Christina yelled out as she approved the idea but then looked down as her stomach had reached a breaking point. Back within Christina's bowels, Bill and the crew were realizing what was happening, they went for their oxygen and started to brace themselves for another bout of gas. Inside the furnace of Christina's butt they could hear some explosions going on, it was the gas exploding from within her, rumbling up to the exit of her butt. Both Captain Parker and the government official was looking at Christina as she started felt the pangs in her stomach reach a climax. Christina finally tilted her ass in that chair and let one rip, a BIG ONE!

It started off with a low murmur, gradually getting louder and louder until it stabilizes into a single loud roar of an engine. She had given out an atomic fart and with glee too. The look on her face was so orgasmic, her eyes rolling as she ripped more and more. It ceased to be a murmur and became a dirty blast of air so forceful that there was a hole slowly being burned by the powerful winds from the fart. Such a windy bowel she had. She could have filled up a balloon with that one fart. It kept going . . . and going! There was such a loud and deep bubbling noise from all the gas that kept on pouring out from Christina's bright red shorts and white underwear. She started laughing to herself as she felt the intense heat and horrific stench pouring out from her vast butt and out into the room. Deep inside Christina's bowels, this deadly, bubbling fart had caught the group off guard, there were expecting more SBDs, not this. The winds that blew out from Christina's anus were also much stronger; at least at the strength of an EF-5 tornado, it blew everything against Christina's white-now brown underwear, which had not gotten a hole in them yet. Christina's plank-splitting butt thunder, the force of that sudden expulsion of original air peeling back the eyelids of both men and coating their corneas with blinding methane. The two grown men panted for air. The ungodly smell hung in the room like a poisonous gas. After a full minute, Christina's fart had finally subsided. It still kept fucking going! It got to its bassiest tone, uttering a long musical note of pleasure, like a foghorn. This was the first big blast of the evening for Christina and it felt utterly good for her.

Finally, the fart winded down. It began to sputter back to a murmur. At times there would be another long strain but then it would cut short with another sputter. It was all so dry and bassy, not wet or juicy. Pure gas, pure Chrissy Gas! Both Captain Parker and the government official were out.

Christina Lopez had completely stunk up the entire library of Winn's shop and more had spread her gas out toward the rest of the shop, but Winn was too quick to cast a spell on the shop to prevent it from spreading out too much more. But to Christina, it was the relief, having an enormous load released from her rectum. She sometimes grunted even more as a sudden force in tone came, and then it went back to its normal, constant hum. With the look on her face, she could imagine her feeling every inch of her stomach feeling less and less pressurized, feeling the gas escape her bowels. She could rub her belly again without that wave of pain. But the gas wasn't nearly as done as she would have thought, but perhaps she wouldn't be farting as much that night. She noticed a small hole was there in her shorts, she had actually burned a hole in her shorts from her intense gas, but once again her underwear weathered the storm. And inside of her underwear, deep with the cavernous crack of Christina's bowels, it surely did feel like a storm. The crew was trying to get an answer back from Captain Parker, to tell them about the frequency and power of that previous fart, but Christina had to alert them that they had fallen unconscious by the power of her fart.
Now, to finish off the evening, Christina went back into the library which had a TV in there and began playing video games, like there was nothing wrong with her or the bomb ticking within her. But slowly, as Christina realized, the food she had eaten up to this point had still given her lots of potent gas. The crew kept on making observations, recording that Christina's previous farts that day were well into the 200s range and that it was becoming more intense, all the combinations of foods that Christina  were eating were all fermenting into a deadly and potent gas and everyone knew it. For about 30 minutes, while Winn and Bailey were in another room, trying to revive Captain Parker and the government official with their magic, Christina was inside the library playing her video games and getting excited and disappointed at times.
Finally, while she was there playing, she felt another gas bubble appear. She radioed to Bill that his crew had better braced themselves, because this felt like an incredible bout of gas that was about to come down upon them. The crew got themselves ready and then Christina started leaning over toward her left with her hazardous butt pointed toward the couch. She smiled with her ass tilted; she pushed out three, mega-sized menacing farts that shook the entire couch and the room around it: BBBBBBBBBBBBBBBBBBBBBBBPPPPPPPPPPPPPPPPPPPPPPPPPPPPPPPPPTTTTTTTTT!!!!!!!!!!!!!!!!!!!!!!!! PPPPPPPPPPPPPPHHHHHHHHHHHHHHHBBBBBBBBBBBBBBBBBTTTTTTTTTTTTTTTTTTTTTT!!!!!!!!!!!! BBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBPPPPPPPPPPPPPPPPPPPPPPPPPPPPPPPPPPPPPPPPPPPPPPPPPPPPPPPPPPPPPPPPPPPPPPPPPPPPPPPPPPPPPPPPPPPPPPPPPPPPPPPPPPPTTTTTTTTTTTTTTTTTTTTTTT!!!!!! Three, long, loud, bassy farts erupted from Christina 's behind, the first two lasting 15 seconds, the last 30 seconds, a full one minute of Christina  farting. The vibration from the farts had shaken even a couple of books of their bookcases. Christina  couldn't but help to laugh at that she had just been able to do, large quantities of her own gas were now being pumped out from between her cheeks at such high velocity that there was an indention into the couch where her gas came from. The library had also started to smell much worse.
Both Captain Parker and the government official, who had woken up from their trance had opened the door, started to step in and were immediately assaulted by a wall of sulphuruos, putrid stench so foul that it could have only been caused by partially digested beans and cabbage stuck in Christina's bowels to brew and ferment for an unholy and unhealthy period of time. They were sent scurrying back out of the door. The government official later on mentioned that he didn't think that he had ever smelled anything that bad, except for the smell of decaying bodies he encountered on a mission to Afghanistan a few years prior, but even the dead couldn't compete with this. Christina 's own special sewer gas continued to spew from her anus as it filled the library with the stench of raw sewage and rotten garbage, the smell of any decaying foods were all there, it was the stench of death. Bill and the crew had been prepared for this, but they had not been ready for these kinds of smells. The oxygen was on full blast for the crew as they tried hanging on to hairs within Christina's butt crack but the stench of Christina's digestive process was still strong in the air. After a few minutes, Captain Parker and the government official came back in to see Christina playing video games once more, smiling as if nothing had happened.
Even with the door open for at least a half hour, the green bean and cabbage gas cloud was still quite present in the library as Captain Parker and the government official came in. The continued to fan the air around them and it seemed that Winn's spell had been working on them at least enough so that they could carry a conversation with her. Christina remained seated there on the couch, playing her games.
"So….you like the idea we have about using your farts as a weapon then?" the government official asked Christina, recalling his conversation they had before Christina had first let one rip there in the library.

"Oh yes…yes I do…you have no idea how much I've wanted to use my farts for the reason of inflicting pain on those who are mean or evil. Every time Bill faces off against his enemies, I just want to pass gas just once and end the fight, but he always keeps me out. So yes…I would like to be used to go into situations and just fart, although I would just like to kick ass too."

"I'm sure your father is just concerned about you." The government official said back, trying to give her a good justification for him keeping her out of the fighting, of course he was right.

"I know…but I'm a big girl now…and I love to help." She said as she began giggling to herself. She was indeed a big girl in more than one way and the government official could see that.

"Well…good then, we would just like to inform you then that we will proceed to Day Two of our tests which will look more into the power of your farts instead of the stench, today's farts were tested to primarily see what kind of odor you would produce, and you sure did not disappoint us." Christina began giggling at the thought of what they were telling her.

"Tomorrow's tests will look at the power of the eruptions themselves and then on Sunday, we will run the final tests, which we hope will create a potent combination, one that will be enough to kill a man. We have some 'test' subjects on Death Row; we will test your farts on them…." Christina continued to giggle and it soon became clear what had happened. "…so…why are you giggling….oh Dear God! Phew! Let's get out of her Captain…." The government official and Captain Parker had just been assaulted by another one of Christina's SBDs. What Christina was giggling at was the fact that he fart took a long time to leave her anus, from the time the government official had started talking to the time that he had finished, Christina was quietly releasing a very hot stream of putrid, chili-powered gas with an extra helping of onions and cabbage into the atmosphere of the already stinking room.

The fart had left her underwear burning with her horrendous fart and she continued to smile as she knew that the two grown men weren't going to leave the room. As soon as they realized what had happened, they began to get dizzy and lose oxygen, in a matter of seconds, they were both out cold once more. It seemed like no one could be in a room with Christina that evening, and this gave her lots of pride. Inside Christina's shorts, the SBD came out with the force of a tornado and the heavy and moist fart stink the place up to unbelievable levels. It was so bad, that even with the oxygen, they could still breathe her gas like there was no oxygen going to them at all, and immediately, all four of the crew was passing out. But there was a more sinister thing going on deep within the bowels of Christina and within the lungs of the crew, they were starting to become more accepting of her gas. They had only passed out because of the intense power of this one fart, but the more and more gas she produced; the more they started liking the gas, breathing it instead of oxygen.

Winn had entered the room where Christina was in and was assaulted himself by the fart, but he took out one of his wands and did a spell that at least quashed the impact. The smell was starting to make Christina herself pretty dizzy and she had to get going to bed. Instead of Section 26, it was agreed that she would sleep upstairs at Winn's shop, in a bed they had already made. A spell would be cast around the door frame that would again keep the smell down to a minimum elsewhere, and the spell fortunately did work. So Christina walked off toward the bedroom, dropping small bubbling farts as she walked up the stairs, momentarily knocking out both Winn and Bailey. Now, even her small farts were causing people to pass out, but they had regained consciousness quickly and cast another spell on the room. Christina then gave a big yawn before heading into bed where she would sleep for the night, launching more farts in her chamber that was a bed.

The crew became trapped in her colon and could feel your world shifting as she slid under the covers, turning onto her side. Trapped among the remnants of previous bowel movements, the smell was even more terrible than even Bill had remembered, as though he had blotted out all notions concerning it. Then they heard a little giggle. A soft gurgle in her bowel, as she pushed, would expel a gas bubble. Exploding around them, the gas would create an intolerable pressure on the crew, the foul smelling gas wafting around them. Pushed powerfully by her muscles, the tightening pressure would reach its apex, causing them to squirm with discomfort deep inside of her rectum. Then, it would flow out her anus, as another long blaster that shook her bed. Her muscles would clench following it, keeping them inside with her gas. Christina slowly fell asleep, her bowels gurgling ominously. The scent inside of her had worsened in light of the fart. The tight walls of Christina's bowels had squeezed around the crew, welcoming them back to the warm depths of her body.

The farts Christina had been releasing throughout the night were nasty and wet farts that shook the inside of Christina's underwear and pajamas like nothing else. Inside, Bill had noticed that he could breathe a little better than he had before, he didn't have to consult his oxygen tank as much as normal, which felt odd for him, but the smell was growing on him. The night in bed with Christina was the equivalent the going through a World War II battle. Christina likely farted some 20 times throughout the night, each of them, long and bellowing. Being through a thunderstorm was better than what these people were going through.  Since her SBD, she had been releasing loud farts that started deep within her anus and rumbled out between her city block-sized butt cheeks and be expelled through her previously white, now brown underwear before being rocked out of the pajamas. Fortunately for the crew, Christina was no longer wearing her tight shorts, which were now on the floor of the room she was sleeping in.

Captain Parker and the government official, for the third time that day had regained cognizance. They walked in to go and take Christina's shorts and give her a new pair to put on for the next day. Captain Parker had picked up her blue jeans and could feel the heat all along them. But at closer inspection, he caught a strong whiff of Christina's farts on the shorts, all the powerful farts the girl had released had completely stunk up the shorts and he had to quickly drop them and retreat from the room to get away from the smell. Finally, a couple of government officials in biohazard suits came in to retrieve Christina 's shorts, and even through the biohazard suits they could still smell Christina's gas on them, though at a much more tolerable level. Back downstairs, Captain Parker and Winn were working on some spells that could help him stay awake from breathing in Christina's farts. The government official couldn't but help to see Christina sleeping there in bed so quietly, slumbering like nothing else was wrong with her. Every now and then, she would release another long and bellowing fart that shook the room, causing the official to quickly close the door; one could only imagine what it was like to be underneath her covers. Christina had an obvious immunity to her farts, regardless to how bad they were, and she seemed to sleep just fine, dreaming of what possibilities she would have for the next day. At which moment, Christina cut another long and magnificent stinker, filling the inside of the covers with more of her noxious farts.


Morning arrived, and it was started by a rumbling noise coming from the upstairs of Winn's shop. It shook the floor with the force of a 5-point earthquake. Up above, Christina had just woken up when she felt a powerful gas bubble appear in her behind. At first moment Christina pushed out a monster, smelly fart, one that would surely wake anyone up within the Chinatown neighborhood, PPPPPPPPPPPPPPPPPPPPPPHHHHHHHHHHHHHHHHHHHHHHBBBBBBBBBBBBBBBBBBBTTTTTTTTTTT!!! It was only a ten second fart but it was enough to wake Christina out of her slumber and up from her bed, gagging from the incredible smell. The crew inside Christina's anus had been shaken awake by Christina's fart and was greeted with a new blast of her vile gas. It shook the crew who had taken their instruments and had recorded this new blast of morning thunder. The video showed to the outside of Section 26 had shown Christina 's anus open up and pucker out a tremendous fart with hurricane-force winds blowing out toward the camera, causing the lens of fog up by the quick rise of temperature. She had gotten up from her slumber to smell her fart.

"Whoa…that was a good one…forget good, that was an amazing one! Good Morning Winn Bill!" Christina yelled into the microphone toward her Winn. Christina then got out of her gas-covered bed and started walking toward the kitchen. Up above, Captain Parker and Winn could feel the floor vibrate from where Christina was walking around. She got up and started walking down the stairs, holding in any more of her farts. There at the kitchen, Christina's breakfast was waiting before her. Again, there were lots of eggs for her, along with another bowl of beans and some more milk. There was also some garlic, from Winn there waiting for her, but Christina didn't mind, anything to keep her farts going. The government official came in to talk with Christina about what she was going to do that day.

"Dear God…that girl is a trash compactor, the way she's eating all that food." The government official said as he continued to observe Christina eating all the food.

"Well…when you have a body like hers, and at the size she is…you are able to eat that much. That's nothing…she ate an entire Thanksgiving meal last year." Captain Parker had said with a distinct remembrance for what had occurred. They had prepared two separate meals for Thanksgiving, one for some of the families living in the complex, such as the Lopez's and one entirely for Christina.  She received an entire turkey, a couple of large bowls of baked beans, one of mashed potatoes, one of sweet potatoes, one of stuffing, one small bowl of cranberry sauce, and a dozen rolls. The farts coming out of Christina's large butt were the stuff of legends, she was farting during her dinner while the other agents were eating and then the real, earth-shaking farts picked up. The traditional post-Thanksgiving dump that Christina took almost destroyed the toilet. They invented a new class for her dumps after that one, a Class 6. It took two plumbers (after the first one bulked at the sheer size of it, the second was offered a hefty payout to remove the crap, and replace the toilet.) Christina always was quite proud of that particular episode and had vowed, to the annoyance of the rest of Section 26, to improve of that this coming year.

"Class 6?" The government official asked Parker, relaying back to his story about Christina's Thanksgiving Bowel massacre.

"We assign a class, unofficially to Christina's bowel movements. With all that food she eats, a lot of it ends up in the toilet. How bad the load is inside determines how high the class is. The one you saw earlier this week was probably a two or a three." Parker explained.

"Two or a three…damn, that was large for one that size, I'd hate to see a 6." The government official had been impressed just by the enormity of the one he saw earlier. His growing interest in this tall Hispanic girl's bowels had caused his member to grow slightly. And just to make things even better, Christina had just dropped a long, egg-smelling burp from her breakfast, she waved her hand around her face to revile in her massive burp.

"We want to take you around the city, into different settings to see the impact of her gas; we will take you back to Section 26 to run some more tests on your farts, tests that cannot be done underneath you. We have contacted the crew in your butt Christina and they have told us that they are doing pretty well this morning. Meanwhile, both I and Captain Parker will be with you during the day, but we will be wearing gas masks, it appears that your farts have crossed a new threshold and we need to be kept from passing out every time you let one rip…" the government official was disrupted by a strong, bubbly fart that erupted from the seat of Christina's underwear. A swamp-gas odor came out, filled with a new batch of eggyness came out from underneath Christina and quickly filled the room. The government official saw this as a good of opportunity as any to test out his gas mask. He placed it on his face and found that he was able to breathe pretty well through it.

"He…he…excuse me." Christina said, now relieved from the immersive pressure she had felt inside. The potent stench had travelled upward into Christina's nostrils and she had taken a big gulp of her own special blend. It felt like it would be a good day for her. The official allowed for Christina to finish her breakfast and blast off another couple of big farts before he got her ready for the trip to her first location. But before they got ready, they wanted Christina to wear something else.

"Could you wear a skirt for us today?" the government official had asked.

"Why?" Asked Christina.

"We want to test your farts against different clothing options, you wore your shorts yesterday, and we'll need you to wear your pants tomorrow, so is there a skirt you have?" the government official looked up at Christina for an answer.

"Sure." And with that Christina was heading back to her room. Captain Parker had noticed something odd about Christina that morning, something he saw when the government official was talking to her. A few minutes later, almost shaking the floor entirely, Christina came down in a tight blue t-shirt, showing off her tremendous front curves and wearing a white and blue stripped skirt that flowed around most, but not all of her large butt. She seemed to have remembered that the skirt had fit her in the past, but now it was only covering half of her ass, with the other, covered in very tight white panties that gripped itself at every curve the 18-year old's enormous rear end. Parker then noticed that all her clothes seemed a little small.

"Christina, are you any…bigger this morning?" Christina looked down on Parker, and felt like he was a tad bit lower, with her breasts practically cutting off her vision of him.

"I don't know…maybe I should check." They quickly got a tape measure and measured up the large girl, and it now showed her at a new height of six feet seven inches.

"Christina…you grew an inch!" Parker said in astonishment.

"I did? Wow! I'm getting bigger!" Christina said as a sudden trumpet-like noise was made from underneath her underperforming skirt. It lasted for three seconds and spread the first wave of toxic gas of the morning into the atmosphere. Christina began giggling, but she was really surprised about her sudden growth spurt. They had measured her at 6'6 just last week, so she grew another inch in just a few days, it also helped explain as to why both her breasts and butt appeared bigger. She then noticed that the foul stench wasn't going anywhere and she went with Parker and the government official over toward the Section 26 van.

Christina entered the Section 26 van and buckled up, with Captain Parker driving. Christina's increased height had forced her legs to be a little cramped in the seat. She caused the van to shake a little when she first got in to sit down. She used as much space as she could while seated there. With her short skirt on, Christina's panties were in clear vision of both Captain Parker and the government official. The government official was really starting to get aroused by the sight of this tall, Hispanic beauty with her too-short skirt covering her too-big ass.  She was giggling with glee as she sat there, now bigger than ever. It had seemed that every part of her body was now increased in size. Captain Parker and the government official had explained that their first test was to see how Christina's farts would do inside an enclosed vehicle. In the back of the van, were several pit bulls, who were barking.

"Aww…doggies." Christina said as she heard what Parker was saying that was inside the van. "We want to see how bad your farts are, do they knock only people out or can they knock out other animals."

"You want me to kill them?" Christina said, as she was a friend of the animals, she really didn't want to hurt any.

"Only knock them out." Captain Parker said, but Christina was still having second guesses about the whole operation, but that was part of the test. Captain Parker figured that Christina was going to hold in her farts much more now, and once she had to blow, it would be a devastating fart. So, for the first 30 minutes, Captain Parker, wearing a gas mask, drove Christina  around San Francisco, and with all the up and down driving of the hills, it really caused her stomach to churn as the food from her breakfast was started to bubble up inside of her.

Bill was inside talking with Scientist C, he was asking her about the prospects of his daughter and how they were doing. "Well…Christina is developing quite well for a girl her age and I see that she will likely become much bigger, and no doubt her gas will become much more as well." Bill was shocked to hear this, but there was something else on his mind, "Is it me…or does Christina's farts not seem so bad today."

"Oh they're bad…in fact, they are on par with yesterday's, but it appears that we are slowly getting used to them, so perhaps we will all develop immunities to them after all. Christina's gas has slowly gotten integrated into our lungs, so it recognizes it as a legitimate source of air; after all there is oxygen in them."  

"Oh…but isn't that not good." Bill was a little worried by that statement, the scientist reassured him, "probably not, but it hasn't been tested, no one has been exposed to flatus that long and it's hard to say what its impacts would be. I'd say after this whole thing is over, we will be a little dizzy from the lack of oxygen, but it should only be temporary, and any effects shouldn't be long term. The crew then continued to look up along the long, immeasurable canyon of Christina's buttcrack. Every now and then, a small amount of light would flash briefly above the crew, almost like stars up in sky, a very gassy, hazy sky. The light only appeared because Christina was wearing her skirt.

Up ahead of the two, they could hear a loud bubbling noise form from above them, Christina  had held her gas in long enough. Back in the van, Christina held her hand down by her panties, trying to suppress the pressure in her stomach, but it became too much, she give off a small groan. Christina then lifts up butt on the seat slightly and you let loose. Her skirt started flying out toward the rest of the van. Her fart was forceful enough to shake the entire seat of the van. Her pucker opens up as a deeply rumbling and sputtering fart comes out of her butt hole. The blast continues on for a few moments and the stench gets successively worse as she pushed and groans. The fart soon stops off, leaving the van smelling something like sewage.

Captain Parker was sweating and wearing his shirt over his face from the stink Christina had made, even with his gas mask on. She grinned inwardly and willingly pushes out this next blast. It wasn't quite as powerful sounding, but it didn't need to sound powerful. This fart came out of her rear, sounding like a large gashed tire, and the sound was quite wet, she swore you could even stain the steel the van was made up of. The loud wet blast stops off and he glanced around at Christina. She continued to laugh at herself as she was waving her hand around in the van.

"Whew…I sure am gassy this morning!" She giggled as she continued to wave the putrid, gassy air around the van. There was a large brown stain against the seat of her pants. Captain Parker looked back at her, sweating bullets...and the grin grew...Suddenly, Christina 's  stomach grumbled and she grunted very hard, stretching out her body as though she were about to yawn. Then a loud raucous burst of gas comes flying right out of her butt at lightning speed, making a horrible trumpeting sound. Captain Parker, even with the gas mask couldn't help but cough a few times and yank his shirt over his nose before opening up a window.

Christina grinned widely and snicker under her breath. The dogs began to bark even more within the van, so Christina turned her butt toward the seat and was ready to let it loose. She sighed heavily and let the gas seep out slowly and steadily, not forcing the whole thing out at once. Captain Parker couldn't help but groan even more and cough violently, veering the van into another lane and almost hitting another car. His eyes were burning and it was becoming hard for him to see. But, this was what he wanted, the dogs barked even louder. At that moment, Christina let the big bubbles shoot out. She farted out humongous bubbles of flatulence that were so loud the metal began to rumble. Both Captain Parker and the government official had felt their seats vibrate to the powerful fart that was ripping out of Christina's oversized butt and short skirt. But if that wasn't bad enough, the smell came in and that was just...awful. Even she was burying your nose into your hands to avoid inhaling the funky odor. Then it finally happens: Captain Parker had to pull the van over. He stopped his van and kicked open the door, coughing and retching vigorously as he stepped outside to get some fresh air.

Christina smiled widely and saw that the dogs barking had been subdued. The horrible and foul stench was enough to make even Christina retch and barf up the food already inside of her. But Christina felt another bout of gas coming, she leaned up again, her belly churning and bubbling mightily. She looked down at her belly and it was bulging outwards, and quivering. The sudden feeling gets worse as a massive, wretched fart rips from between her butt cheeks and blew a thick stink into the air. The fart carries on for a few moments, getting fouler and thicker.

"Christina! What the hell is wrong with you?!" Captain Parker yelled as he continued to get some fresh air, even with his gas mask on.

"What? You wanted me to fart." Christina said giggling as she got out of the stink zone she had created in the van and walked back toward the back of the van. She opened the door to the back and saw was blasted by her powerful stench. It caught her off guard for a moment, but soon it she was able to see the effects of her handiwork, the dogs were passed out, if not dead, for her farts.

"Aww…poor doggies, my fart took them out." Christina looked down at her body, which now had the ability to take out pit bulls. She looked up toward Captain Parker, "Phew that was a stinker…so…what my next test is?"

Captain Parker and walked with Christina down a street toward a local Taco Bell, he was going to fuel her up on fast food, and not just any fast food, but the gassiest possible. Meanwhile, Christina every now and then had to push another large fart from between her cheeks, creating a vibration noise from within her skirt and assaulted the nearby passerbys with her awful stench. At first, those passerbys were wondering what Captain Parker was doing with a gas mask on, but they soon found out, especially the two kids who were knocked out on the spot just because she had passed them and ripped one at the same time.

Finally, they arrived at Taco Bell where Christina slyly walked in to gouge herself on lots of bean burritos and other assortment of Mexican food. At her new and improved 6'7 height, she stood out even more than ever before the rest of the people at the restaurant. When she walked up to pay for her meal she had to bend down a little to pay the person at the register, giving the people behind a good view up her short skirt and up her white/brown panties. Though, there were also some looks by some teenage boys as they were looking at more ass than they had ever seen before.

They could smell what could only be described as a mixture of eggs, beans, and shit. Back down in her ass, Christina's previous farts in the van had been devastating to them to say the least, the farts created from within Christina 's bowels had turned up to an unexplainable level and the gas masks the crew were wearing while piping in the oxygen were not helping matters at all. Oh…they were getting oxygen, but just not as much as expected. Meanwhile, Scientist B had become more obsessed with walking around the campsite up to Christina's butt hole and taking his mask off every now and then just to get a deep whiff of her farts. He was already burned up as much as possible and this was not going to help things anymore.

Meanwhile, Bill was telling the crew of a story of when Christina was flying with him across the world, and had eaten beans that previous day. The plane ride was not pleasant to say the least, and she had cleared out the plane several times that flight, except for the fact that the plane itself couldn't be cleared. Several on board had opted for using their oxygen masks that came down from above them, even though the plan e was flying perfectly fine. But alas, Bill had always regretted this one little quark about his daughter, he had no problem with Christina following him around, and although he never admitted it, he did like her presence and the fact that she managed to save him reputably, it was just the gas. The horrible gas that came out from butt on a continuous basis, it was the bane of his existence for the past few years. He always had to put up with it, along with his growing daughter. He had thought that by thing point, with his connections to the federal government the problem would have been remedied, but Christina's farts only grew worse and her entire digestive system only continued to perplex doctors who studied it. This shrinking experiment was only the latest in a series of attempts to fix the problem. As he continued to think of this, there was another loud fart that started erupting from his daughter's anus, blowing his hair with her moist, stinky wind.

PPPPPPPfPfPfPfPfPfPfPfBBBBBBBbBbBbBbTtttttttttt!!!!! An immense pressure made her whole body shake; she squirmed and found herself absent mindedly bending forward in an attempt to force out as much built up gas as she could. The fart went on for ten seconds and rattled the plastic seat that Christina was seated on, which she was eating her Mexican food. It was a site to see, this tall, massive, Hispanic girl with her large butt, covered only partially by this blue and white skirt, shaking the hell out of the seat with her massive fart. The other patrons in the restaurant were looking at Christina  with a disgusted look, as the 18-year old Hispanic teenage could only smile at what she had created, but it wasn't the noise that had affected the patron's ability to eat in the restaurant, it was the stench. An unholy marriage of the beans, cheese, onions, eggs, and milk all rolled into one, barf-inducing smell that quickly filled up the entire place. It was a fart unlike any that the other patrons had heard before and it caused their eyes to water and their mouths to gag from the sudden lack of oxygen. Immediately, the place was emptied as some people took their meals, while others left there's there, giving Christina even more ammunition.

Captain Parker was now starting to see what impact Christina could have for practical purposes, he didn't even tell Christina to do this, but she did anyway. One rump-shaking fart on the seat was all she needed to declare the restaurant hers. Eventually, Christina had finished her meal, as well as a couple of more farts and Captain Parker had announced that it was time for the next test, but it was over at Berkley, across the bay from San Francisco. Back inside Christina's butt, the crew had been baffled, despite the strong potency of this fart from Christina and the incredible smell that came out, they had been unscarred by the fart. There was no time for them to reach for the oxygen, but instead of passing out, they seemed to have been able to breathe in the contents of the fart.

"Think nothing of it, we were probably lucky." Scientist A had thought.

"But keep your oxygen right there…the human body still needs it to, and the last I checked, we were all still humans." But Bill was starting to get worried about another prospect, they were running out of canisters of oxygen, they had used too much of it already.

Captain Parker and Christina went down into the BART system down below the streets of San Francisco. As the kid went through the turnstiles of the station and onto the car, she felt more bubbling taking place inside of her. It was like a way of all those Mexican foods, taking turns at digesting within her body into a more putrid form, a gas that would cause damage she felt on the subway train, and the longest part of the trek was almost there. Christina walked onto the train, feeling like she was on top of it all, her head was no more than a half foot from the ceiling. Captain Parker sat down on the train, but Christina remained standing on the train, leaning against a pole. Her massive body stood over everyone else on the train. Her breasts rose above nearly everyone else who was both seated and standing and her ass hung up above all those seated. Those seated next to where Christina was standing were able to look up Christina's skirt to her panted asscrack. Not that it mattered much since most of Christina's panted bottom was showing. It seemed that the further the day went, the smaller the skirt got. Christina loved the attention she was getting for those who were watching. Christina's skirt-covered ass hung out like two basketballs off her body. She could only smile, because while those people were watching her tremendous ass, she was preparing it to release her ultimate weapon.  

As the BART train went out of Embarcadero Station it began going through the long tunnel underneath San Francisco Bay, it was 12 minutes to the next station, and Christina's rectum was about to climax. On the moving train there was nowhere to run to, nowhere to hide. It is literally a target-rich environment and Captain Parker knew it, in which everyone still breathing gets a little. It's was only a question of the thread count of her pants, the thermodynamic properties of her fart (measured in BTU's per cubic inch at standard ass temperature and pressure), and the apparent temperature of the exothermic exhaust against her sphinctronic nozzle. Turmoil has engulfed my lower intestinal tract as the processing of certain foods is in dispute. While unsuspecting passengers endlessly endure an otherwise dull train ride across the bay, Christina's ass has secretly dispatched two rancid assassination farts -- to seal the fates of all on board. Christina's anus muttered a quiet "ba-fufffff... frawffffffffff." This deuce of bad boys was searing hot and utterly putrid. The vileness was unparalleled. It was, without any doubt whatsoever, extremely objectionable. The two farts quickly filled the entire subway car with a warm, humid gas that no one at the moment knew where it came from. Only Christina knew that it was coming out of the largest butt on the train. And the staying power that this fart had, she had cleared subways before, but never this quick!  The passengers' reactions were a thing to behold. She heard gasps of disgust. Mutters of discontent. The kill zone grew as, with the dispersal of the cloud to which she had just given birth. Deep within Christina's bowels, a crew of four adults, shrunken to the size of ants was gasping in horror of these latest farts Christina was releasing.

"Oh no…it reeks of Taco Bell." Bill complained, knowing the source of the stench all too well. But Christina was not done with her gaseous onslaught. There was a larger unrest in her large intestines. Several thousand cc's of turdular fumes have declared their intention to leave the Digestive System. After a couple of minutes had passed from Christina's first fart, the people in the car were still waving their heads around in horror to the stench and praying for the ride to be over. The Christina decided to let another one rip; it was one round of nasty-ass butt-bombs after another. They were reasonably hot -- not the searing fire described above, but still well to the right of "warm." What made them special was that they were being manufactured and released at regular intervals. She was launching a regular series of farts and all of a sudden the time between farts had increased dramatically and the smell and temperature was getting exponentially worse.  Now, the people in the train were becoming worried. It was clear now that those massive farts were coming out from underneath this large butt from this tall Hispanic teenager.

As the train how now reached the midway point across the bottom of the bay it seemed that her brain received flash traffic from her ass that a lethal charge of sphinctrous sphinctride was locked and loaded. She tilted the side of her backside and performed the time-honored Right Cheek Sneak, losing the compressed pocket of penultimate stench unto the huddled masses. This latest fart blew from within the vast rectal cavity of Christina and through the tight white panties and finally as a strong, pungent, warm wind that blew the skirt like a flag in the air. Those on the subway car were now horrified as they now knew the source, the young Hispanic girl. Captain Parker quickly grabbed his gas mask and placed it on. Perhaps due to the Venturi effect, the gas charge quickly entered the train Air Current and reconfigured itself from a tiny painful pocket of sour acid fume into a broad, miasmic fartstrosity. Riding the breeze of her previous fart, it snaked its way through the legs and luggage of standees, up the back stairs, and onward until it met and infiltrated the nasal passages of council of prepubescent female in the back of the car. The girls had yelled out, "Ohmygod that's *gross*!"  

Christina then started giggling to herself, her Mexican food had created too much gas, and there was so an overflow in the stomach. She started feeling those dreaded cramps. There was a bowel-shaking 7.9-magnitude earthquake occurring in her intestines and it resolved with another fart, a strong, bubbling fart of epic proportions. Out of her asshole, propelled large pockets of toxic gas. The odor was horrific, much like a decomposing corpse smoldering in the hot California sun. The strong rotten egg odor had left everyone on the subway car asphyxiated with only Christina standing and Captain Parker seated there.

"Oopsie…I'm sorry." Christina said as she stood up there in the subway car. After another ten minutes, the subway had arrived at the station in Berkley, where Christina was going to go. As they left the subway car, still strong in Christina's massive stench, the fart smell had been forced out of the subway car and into the station, giving it a slight tingly sewer smell. Christina then dropped two more bombs as she walked through the station and the train left. What was once a busy station had several people lose oxygen temporarily while others had quickly made it for the exits, not knowing that it was a teen girl who had caused the devastation.
