	As she waited for her son to get off of school, Nicole’s stomach grumbled at her, and she winced as she brought a hand to it. Earlier that day she had eaten a large amount of tuna, which had the predictable effect of making her feel bloated and gassy. Her digestive system was hard at work breaking down the protein-rich food, producing a large amount of putrid gas that noisily worked its way through her system.

        Five minutes later Nicole spotted Gumball as he walked out the front door and down the stairs. As he approached her car he made eye contact, but quickly broke it and scratched the back of his head. He got into the passenger’s side of the car, shut the door, and buckled up. Nicole was suspicious, however, and waited before driving off.

        “What’s wrong, dear? Did something happen at school?” She asked, turning to him with a concerned look on her face. He avoided meeting her eyes, instead looking down at his shoes as he fidgeted.

        “Uh… not exactly.” He said.

        “Then what’s the matter?”

        “I, err…” He mumbled, trailing off. He took a deep breath and sighed, then spoke clearly. “I got my report card back.”

        “And?”

        “Uh… I failed. I guess all that procrastination finally caught up to me.” He said, anxiously tapping his fingers together. Nicole’s brow lowered, and she recalled that it was the end of the semester.

        “But… I thought you said you were doing a lot better?” She asked.

        “I guess I was wrong.” He said. “I also might’ve… exaggerated a little. Hah…” He said sheepishly, tugging at his shirt collar as a bead of sweat ran down his forehead. He could feel his mother’s gaze burning into him, and he glanced up at her to gauge her reaction. She was clearly upset, and he went pale. She let out a frustrated sigh and shifted her car out of park, driving off without saying another word. Gumball sat in silence, trying to occupy himself by staring out his window.

        Nicole thought about how she should punish him as she drove back home. Her gut interrupted her train of thought with a noisy grumble, but it gave her an idea. She made a turn off the normal route to delay their return home and pressed a button on her door that clicked the vehicle’s locks shut. Gumball was startled by this, waking up from his daydream.

        “What did you do that for?” He asked, confused. “Uh… are we still going home?”

        “Just a short detour, dear.” She said with a sweet voice. Her stomach gurgled again and Gumball gave a nervous chuckle. “Nnph... those tuna tacos really aren’t agreeing with me. You might want to hold your nose.” She said, smirking.

        Pressure built in Nicole’s abdomen as gas rushed to escape her bowels. She leaned to one side while lifting her leg and let out a wet, bubbly fart that flapped her skirt as it rumbled out. Gumball was engulfed in a dense green smog cloud that reeked of sulfur and fish, a smell that caused him to gag the moment he inhaled it.

        “Eugh! Mom, that’s disgusting!” He said, clasping a hand over his nose. His eyes burned with irritation when the fumes invaded them, welling up with tears as he coughed and hacked. Nicole snickered and used her paw to fan the gas in his direction before sitting down flat again.

        With no way for the stink to escape, it simply distributed itself across the interior of the car until the entire vehicle reeked of ass and rotten eggs. As it spread out it became less visible, but the intensity of the odor hardly let up. Gumball was anxious to escape it, using his free hand to roll down his window. To his surprise it did nothing, prompting another giggle from his mother. He realized she had already locked that too, and his stomach sank.

        “God, this reeks. Please, let me open my window. Just a crack!” He begged, receiving no reply. Seeing no other option, he tried to open the door itself and got the same result. As he pulled at the handle in futility Nicole let out another fart, vibrating her car seat and adding a second cloud of noxious gas to the vehicle’s atmosphere.

        Gumball retched and clutched at his throat as he struggled to breathe the increasingly toxic atmosphere of the car. The temperature gradually rose after the second fart, and soon enough the interior of the vehicle was like a sauna. Sweat dripped down his head and his eyes went bloodshot, while the windows fogged up until it was impossible to see through them. Nicole made another pointless turn that added several minutes to their journey and Gumball grew increasingly desperate to escape. He clawed at the window, raking his fingers down it in a panicked attempt to get out. In doing so he left handprints on the windows, though they quickly faded away as the fog reappeared. To continue driving safely in these conditions Nicole activated her windshield wipers, giving her a clear view of the road.

        Nicole’s stomach churned audibly as she blasted ass again, pumping out gallons of awful-smelling flatulence over the course of several minutes in a relentless barrage. His lungs burned and ached for fresh air, kept away from him only by a thin layer of glass. He gasped and sputtered, breathing laboriously as the oxygen content of the car was replaced with methane and lightheadedness took over him.

	The last thing Gumball remembered was the sound of a silent fart hissing from Nicole’s ass accompanied by a quiet moan of relief. Only a moment after, he was hit with a rush of miasma that bordered on lethal. It smelled like death and rot, and his stomach twisted into knots the second he took it in. Initially he feared it would push him to lose his lunch, but instead he blacked out and collapsed into his seat. He was unconscious, knocked out cold after a single whiff of the fart. Nicole gave a sigh of relief and smiled, her bowels settling down for the time being. She turned back onto their normal route and took it the rest of the way home, pulling into their driveway not long after.  The long and torturous journey was finally concluded, having taken three or four times longer than it should have.

        Nicole unbuckled her seatbelt and waved a paw in front of her face, growing weary of her own stink after breathing it in for so long. When she opened the door the pressurized gas that had built up within the car was released, creating a plume of opaque smog that rushed out past her. The fumes formed a cloud that rose into the air, which gradually dissipated over the course of several minutes. Nicole took a deep breath, enjoying the smell of fresh air while Gumball stewed in the decompressing fart chamber she had created. It would no doubt take many hours for her car to properly air out, but that was something she would deal with later.

        Nicole walked over to the passenger side of the car and opened the door. She carefully lifted Gumball out of his seat and into her arms, then carried him inside the house with her. Nobody else was home, which presented yet another opportunity. She carried him up the stairs and into his room, where she laid him down on the bottom bunk of the bed. He snored quietly, his breathing rugged after having filtered countless gallons of noxious gas through his lungs.

        Nicole stood at the bedside, contemplating her son’s punishment. She wasn’t confident that a single hotboxing would get her point across, and so she decided to cement it with another round of stink torture.

        She climbed up onto the bed with Gumball, then lifted her skirt and pulled her panties aside. In doing this she exposed her sweat-damp butt, which she then unceremoniously plopped down atop his face. He was startled awake when he felt a heavy and squishy weight smothering him, and he grabbed at her hips as he instinctively tried to pull her off. The smell of ass filled his senses and he groaned in discomfort, wrinkling his nose at the odor. He tried to talk, but his voice was muffled and barely audible from beneath her asscheeks. He wasn’t sure what had happened at first, but when he realized his face was wedged into his mother’s butt, his face went red and he struggled with renewed vigor. Nicole giggled and clicked her tongue at him.

        “Don’t try to get out of your punishment, Gummypuss. Just relax and breathe deeply~” She cooed. Nicole reached back with both hands and peeled her buttcheeks apart, allowing Gumball’s snout to sink deeper between them. Once he was firmly lodged into place she let go and allowed her cheeks to envelop his face. She smirked as she pushed out a long, windy burst of flatulence right against his nose, subjecting his sense of smell to a point-blank blast of concentrated stink. His reaction was immediate and one of revulsion, his cheeks going green with nausea as his stomach churned and his eyes teared up. He coughed and hacked to the point of breathlessness, and every bit of air he did manage to get in was heavily polluted by the fart. He dug his fingers into her hips as he leveraged all his strength to get her off, but the vast size difference between them was too much to overcome. He let up and panted in exertion, laying flat on his back as he huffed up the fumes against his will.

        Nicole let out another fart, warming and vibrating her son’s face while filling his nose with the rotten stench of digested fish. The scent soon reached her own nose, and she was surprised at the potency of it.

        “Phew! Can you tell what I had for breakfast?” She teased, rocking her hips side to side as she worked her hole against his nose. Nicole grunted softly as she pushed out a short but forceful fart into it, causing him to sputter and wheeze as he was forced to take every particle of the gas in through his nostrils.

        After giving a taste of facefarting to her son, Nicole moved on to the next part of the punishment. She lifted her rear off of Gumball’s face, allowing the oxygen-deprived boy to gasp and pant for air. After only a few seconds of the relief, however, Nicole reached down and took a hold of him by the chin.

        “Open wide, hun~” She said gently. She pried it down to force his mouth open and dropped her ass back atop his face. With her butt blocking the closure of his mouth, she shifted around until she felt her pucker brush against his tongue. Try as he may, he was not able to close his jaw to protect his taste buds. He groaned in a mixture of fear and disgust.

        Nicole grunted and squeezed her eyes shut as she ripped a long, wet fart into Gumball’s mouth. His face drained of all color as the putrid smog was pumped through his lips, the gas blowing over his taste buds and filling his cheeks. A good amount of the fart flowed up his nasal passage and blew out his nose, and his entire body shuddered at the rotten stench it brought. His tongue dried out under the lengthy torrent of fishy butt blasts, and he prayed internally for unconsciousness.

        “Swallow it, hun. Go on.” She said, pushing him to ingest her emission. Gumball’s lips quivered as he held the fart in his mouth, trying his best to swallow but unable to force the muscles in his throat to cooperate. “Come on, hun. I know you can do it.” Nicole said. After several more failed attempts he managed to choke the gas down, sending the noxious fumes through his esophagus and into his stomach. Right after his gut was flooded with Nicole’s fart, his body decided to turn the rotten substance away, sending it back the way it came where Gumball belched it up loudly. With his mother’s butt blocking its exit, it had nowhere to go, and it simply festered around his tongue. He groaned as he was forced to taste it for a second time, though it mercifully stayed down after being swallowed again.

        After hearing her son finish the last fart, she ripped another to replace it, reinflating his cheeks and drawing out a repulsed groan. Gumball was forced to repeat the process, filling his stomach to the brim with Nicole’s gas. Each consecutive burst was more foul than the last, until Gumball was retching uncontrollably and unable to take any more in. Nicole could feel he was reaching his limit and on the verge of unconsciousness again, and she let up a bit. She lifted her ass and allowed him to burp up more of her flatulence then gasp desperately for air.

        “I shouldn’t have to lecture you about doing well in school again; I’ve done that plenty. Just know that this is what waits for you at home if you don’t shape up, understand?” She asked sternly. Gumball seemed dazed and groggy, and gave no reply. “Listen to me, young man! Do you understand?!” She asked again, raising her voice. Gumball snapped to attention and nodded quickly, his pupils shrinking in fear. “Good. Now, while I’m still here…” Nicole used both hands to spread her cheeks apart and lowered her ass again, causing Gumball to kick and struggle frantically while letting out muffled pleas for mercy. “Pucker up, I’ve got a little bit left in me. And I’m not going to ask twice.” She ordered.

        Gumball obeyed with haste, squeezing his eyes shut as he puckered his lips. Nicole pressed her butthole against them and the musky flavor it carried crept into his mouth, eliciting a whimper of anticipation. She held this position for a few moments, a smile stretched across her face as she forced Gumball to make out with her ass.

        Once Nicole was satisfied with the worship she strained and grunted, producing a fart as fishy as it was rancid. It rumbled out from between her blue-furred cheeks, vibrating her son’s face and provoking a fit of guttural dry heaving. The forceful burst of gas blew his fur back, while finding its way into his nose as well as between his lips. 

        The fart came to a sputtering end as she emptied the last of what was in her gut, and she carefully lifted up from his face. She climbed off the bed and back onto her feet then pushed her panties back into place and allowed her skirt to lower. Gumball laid limp on his bed, still breathing and visibly conscious, but stunned and immobile. A wispy green aura of stink hung around his head, and a smokestack of her gas rose from his open mouth. His eyes were open but in his pupils’ place were two vertigo-induced spirals that swirled around in circles. Nicole giggled when she saw him, entertained and flattered at his reaction to her gas. She patted him and planted a kiss on his forehead despite the strong reek of rotten eggs he now carried. He was catatonic, giving no reaction aside from some faint mumbles of gibberish.

        “Rest well, dear.” Nicole said before turning to leave the room. She stopped herself just before she walked out and continued, “Oh, and you’re grounded for a week.” The female’s face lit up with a smile, and she slammed the door shut on her way out.
