BBRRROOOOOPPPTT! 

The sound could be heard from miles around, echoing throughout the forest and all knew what it was. It was the sound of a particular Charizard releasing her bowels. This wasn't any Charizard mind you, it was a giant Mega Charizard(X). This titan of a beauty ruled the land she walked on, cutting loose whenever she could for she had a little toy beneath her. A little Lucario toy wrapped around her enormous butt and face pressed up against the giantess' tail hole. Each fart that spewed out of the Charizard's bowels, the Lucario sniffed right up with a smile on his face. No matter how smelly, or big, he made sure to breath all of it in.

The Charizard strolled through the forest, letting out a deafening: PPPRAAAAAAPPPTTT! "Ahh, I hope you enjoyed that one my little pet." Charizard said, pulling on the ropes wrapped around her hulking thighs that bound her Lucario. She could faintly feel his nose at work as he sniffed away face deep in her tail hole. A big smug grin extended across the Charizard's face as she felt his puny whiffs. 

She continued her trek through the forest until she came across a large clearing full of other pokemon. All of them turned to the thundering footsteps that approached them to see a titanic Charizard looking down on them. They all turned and ran in fear at the sight of the giantess, but Charizard didn't care, all that mattered was her and that little smelly Lucario.

Charizard reached down and untied the ropes from her flanks and let the Lucario fall to the ground. She turned around and looked at her toy, already on his knees, tail wagging like an excited little puppy. "It's been awhile since we've had a 'sit down' hasn't it pet?" she asked queried. Lucario nodded his head in agreement. "Well then, why don't we fix that now?" The pet's eyes lit up with thrill at the Charizard's words as he laid himself out on the ground for his master. "That's a good pet." The giant said, turning to face her gargantuan butt to him and letting herself fall backwards. 

Time seemed to stop as the dragon's mighty ass descended upon Lucario. His master's ass was an idol meant for worshipping, for appreciating and he was one of the very few with not only the willpower, but the strength to handle the power it held. For years he had been at the will of his master's big gassy butt and enduring whatever it threw his way, but his absolute favorite thing was their'sit downs'. 

*THHUUUMMPP* 

What could only be described as an earthquake shook the surrounding forest as the Charizard sat herself down on top of Lucario, several tons of scaly cheeks smothering him. Trees around the clearing were all uprooted and fell over, others further away tipped over and some even further than those simply lost all their leaves. Charizard began to grind her bulky bottom down on top of her pet, making sure she was nice and comfy for the 'storm' that was soon to come.

*GGRROOOOAAARRR* 

An intense roar rumbled inside the macro's stomach, a sign of certain demise for most, but not Lucario. Lucario nestled his face up against his master's tail hole and waited for the "gift" that was soon to come. Charizard grunted just before the storm hit: FFRRRUUBBBBLLLBBBLLPPTT! The first round thundered out of Charizard's bowels, giving her little pet a hefty face full of her natural gas for him to huff up like his first ever breathe of air.

Leaves blew up high into the air from the force of the explosion of gas and sent up into a whirlwind of stink. PPRROOOOBBBRRRTT! A second dose of fumes broke out of the giantess' intestines for the Lucario pet to inhale. Only two farts into the sit down and his lungs were already aching from the burning sensation due to the miasma floating around in his lungs, but still he sniffed away. 

PPBBBBLLTT! BBRUUURRRTT! PPRAAAAAARRRRFFFFTT! 

Three more farts detonated from the Charizard's tail hole, this time blowing the trees behind her away. She was having some stomach issues today, but she did not realize it would be this bad. Good thing she had such a well-trained pet to take the brunt of it all. 

Lucario's nostrils stung with the heat of molten lava from his macro master's fumes. He still laid face deep in her rectum, ensuring he would smell each bit of Charizard's aroma each time one was expelled, but still he sustained himself and kept his composure. He absolutely refused to displease his master, after all she was the world to him. She cared for him, made sure his need for flatulence was filled every minute of every day and he returned the favor with his obedience and affection. 

BBRRRPPPPRRAAAfffftt!

A juicy toot turned silent invaded Lucario's senses, this time travelling down his mouth as well and into his gut. The tainted air warmed his stomach and eased his mind. The burning sensation in his lungs had died down as his body was filled with contentment from the luxurious feeling of his stomach being full of Charizard gas. He moaned to himself as he gulped it all down.

*GGRRRMMMMOOAARRR* 

The mighty roar returned yet again, this time with a lower, but more intense rumbling. A massive blast was about to nail the Lucario right in his face, but he was ready. He gripped his master's flanks and pressed his face firmly in her tail hole. Lucario felt the vibrations travel down his master's gas chamber, eager to buffet him with the force of a cat. five hurricane and he in turn was as eager to ingest it. Charizard pressed her weight down on top of Lucario and pushed.

PPPffffffffrrRRRRAAAAAABBBBBBRRRLLLlltt!

Lucario's face was blasted clean out of Charizard's tail hole from the sheer strength of her fart. The wind blew his ears and appendages back and filled his mouth and gut fit to burst with miasma. Lucario tried his best to push her face back in his master's wondrous tail hole, but the gale was much too strong for him. 

At last, the fart died down and dead silence fell upon the forest. Charizard panted, trying to catch her breathe after that dreadful expulsion. Something worried her though, she did not feel her pet beneath her. Did she kill him? Was her precious pet obliterated by her gas? Charizard's expression turned to that of smugness, to worry and panic. She quickly stood up and turned back. Lucario was laying down on the ground, giving his master a thumbs up to insure her that he was all right. Charizard sighed in relief, "You had me worried there, pet." she explained, now feeling relaxed her pet was unharmed. She reached down and picked him up in her claws.

Lucario was carried up to the giant's face. He reached out and hugged her, "Thank you for that, master!" he exclaimed to the Charizard. "You are most welcome little one." she replied. "But we must get going now." Lucario nodded his head before Charizard brought him back down to the ropes dangling from her body. She tied him back up and pulled them up around her thighs, yanking them up hard to make sure he was nice and snug beneath her massive tush before walking off.
