Early afternoon in Jasper park, Kate and her younger sister Lilly were laying out under a large tree in the forest. "Those deer were so good, don't you think Lilly?" Kate asked. "Y-yeah, I don't think i've ever eaten so much in my life." Lilly said, rubbing her extended belly. Kate looked at her own extended belly, realizing she needed to work off this extra fat. She rolled over onto her stomach and stood up, looking over to her sister. "Hey Lilly, let's play a game!" Lilly looked at her sister with interest. "Oh OK, sure Kate. What should we play?" Kate pondered for a few seconds before concluding what she wanted to play. "Let's play hide and seek!" Lilly rolled over and stood up. "Okay, you count and i'll hide." she said. 

Kate gave a toothy smile before closing her eyes to count, as she hears her sister run off. "One, two, thr-" *Grrrrooooaarrr* Kate's stomach growled as she felt some discomfort traveling down her stomach. "Ohhh, I think that deer is disagreeing with me..." She said to herself, bringing a paw up to her stomach. "Three... Four... f-five... s-six... S-s sev-" *GRRRrrrrrrrrr* another growl from Kate's stomach confirmed her suspicions. Kate's face scrunched up in agony as the pain in her stomach persisted, until a small burst of gas expelled from Kate's butt. Kate sighed as her stomach pain slightly diminished. She continued counting. "Seven, eight, nine, ten!" Alright, here I come Lilly! The wolfess yelled out. Kate looked around, pondering which direction her sister went. West of her has far less trees, but also has an abundance of bushes. To her east, the forest was more dense with trees, both short and tall and also the direction of their packs dens, while to her north was a small creek and some rocks and lastly the south was simply flat grasslands. Kate looked towards the dense forest again, "Well Lilly does love smaller animals and there is usually more of them in the forest." she said to herself before trekking forth.

Kate looked behind tree, after tree, after tree looking for Lilly. Checking hollowed out tree trunks, under piles of leaves, even looking up at the branches to see if she might have climbed up one of them to no avail. Kate grew uneasy as she didn't believe it would be so difficult to find Lilly and on top of the stomach pains bothering her, she was growing irritated. Seconds went by, then minutes and before Kate knew it, it was late afternoon and Kate was still unable to find her sister. "Damn it, I can't find her anywhere! And my damn stomach is still killing me!" the alpha thought to herself, realizing her whole afternoon was wasted just looking for Lilly. Kate had a look of exhaustion and pain on her face. "I just had to suggest hide and seek. I swear when I find her-" Just then, she saw something just up ahead. Peeking out behind one of the tall pine trees, a tip of a white tail! Kate's expression lit up at the sight and ran up to where the tail was. Kate reached the tree in a flash as she jumped out to see that it truly was Lilly, sitting upright against the tree trunk! 

"Oh, you found me Kate! You won!" the white wolfess said. "And it only took you all afternoon." Lilly giggled. Kate wasn't laughing however, she was fed up with searching for her sister aimlessly for so long and wasn't about ready to let her lowly sister get off easy. *GRRRRROAAARRRRR* Kate's stomach growled noisily, still irritating the alpha. Kate saw Lilly tilt her head in curiosity, "Are you alright sis?" she asked. "Yup, i-i'm fine." Kate replied, her stomach pains worsening. Just then, an idea came to mind. The alpha wolf's eyes veered in Lilly's direction. "Now that i've won, I say we play another game." Kate said. Lilly looked up with interest, "Oh okay! How do we play?" the eager omega asked. A mischievous grin spread across Kate's face, "Like this!" she spoke enthusiastically. Kate spun herself around and pointed her butt directly at Lilly and began backing up until it was only a few of inches from her younger sister's face. Kate then lifted her tail, presenting the white wolf to her bright pink butt hole. 

The pink pucker opened up slightly before a soft sound emitted from it that was immediately followed by a gust of warm air and a strong odor that hit her right in the face. The odor stunk of something resembling rotten meat and skunk spray. It took a second for Lilly to realize that her sister had just farted in her face! Lilly flinched at her sister's gas. "Come on sis, sniff it up!" she heard Kate say, as another burst of gas struck her in the face. Lilly covered her snout with her front paws to prevent the stench from entering her nostrils and closed her eyes. "Kate that smells really bad...!" Lilly yelled to her sister, but she refused to listen to her. Lilly opened her eyes only to see Kate backing up towards her. Lilly stuck her paws out to push her sister away, but was hopeless to stop her sister from gently pressing her tail hole against her own nose. Another smelly blast spewed out of Kate's rectum, this time directly into Lilly's nostrils. Lilly's eyes watered slightly from the stench. "Lilly, I said smell it. Now." Kate said in a stern voice. Lilly couldn't believe Kate actually expected her to listen to her grotesque command! She heard a low growl from Kate, "If you won't smell my farts, then i'll make you smell them!" Kate yelled. Lilly yelped as Kate tackled her onto the ground and onto her back. Lilly couldn't help but whimper as she stared into Kate's malicious glare. She had never seen her sister with such a wicked look on her face. 

Lilly could only watch as Kate once again turned and pointed her flanks in her direction before they dropped right down onto her snout, with the tail hole planted directly on her nose. Kate's tail lifted just as another fart blew directly into Lilly's nostrils. Lilly shut her watery eyes as the fumes entered her sniffer. Kate then spoke up, "While you may be my younger sibling, you are still just a lowly omega bitch who can't listen!" she shouted "I'm the alpha here Lilly. The pack leader! Which means you HAVE to do whatever I tell you when I tell you!" Lilly then realized that her sister was entirely right. Kate was the pack alpha, while she was nothing but a pathetic and disobedient omega. Lilly's ears drooped as she decided to give in to her sister's demands and began to sniff away at her sister's fart coated tail hole. "That's a good little omega." Kate exclaimed, "You are learning your place in this world." Another series of smelly wind spewed into Lilly's nose.

The little omega was in hell as her elder sister sat tall atop her face, giving her constant doses of alpha gas to sniff up. She would hear the leader's murmured moans each time she would release a stinker straight into her nose. "See? Isn't this much better than resisting me?." she heard Kate state. Lilly gave no retort and simply continued to sniff her sister's butt hole. *GRRRRRRRRRRRRRRR* The omega heard the alpha's stomach growl once more. "Unngghh... Lilly... Lilly open your mouth. Open it right now." she heard Kate demand. Lilly knew what was about to come, but was powerless to stop it. The white wolf gulped before slowly opening her maw. The white omega felt her sister's butt quickly lower onto her open mouth and pressing her tail hole against it. Lilly gagged as she got a taste of her sister's rank anus, "Oh man... this is a big one!." Kate said. Lilly's eyes shot wide open as Kate released a monstrous blast into her mouth with gale like force. The fart echoed aloud in the omega's mouth, filling her cheeks to the brim with gas. Lilly flailed her legs rampantly in a desperate attempt to escape. "Ughh, s-stop fighting! Just.. ahhh.. just swallow it!" Kate commanded over the sound of her thundering fart, but the bombastic bomb was far too foul for the omega bitch to handle. Lilly's flails died down to a halt and tears rolled down the white wolf's cheeks as she slowly began to lose consciousness. Just as Lilly was about to pass out, the gas bomb ended. "Whew, that was a hell of a fart!" she heard Kate say while panting. Lilly watched as her blurry sister stood up and turned to look at her with a giggle. "Guess we just found your new job, Lilly." the alpha said. She saw Kate lean her head down to hers before she whispered into her ear "As my personal fart sniffer." Lilly's ear twitched in disgust up on hearing what her new job for the pack was just before losing consciousness.
