A long, dull groan reverberated through the sweaty confines of Kali’s crack. “Not again,” Max thought, looking up in fear. This was a sound he’d become acutely familiar with during his time in her butt, and quickly learned to dread; the wet gurgle of the amazon’s bowels signalled the impending arrival of another rancid fart.

 

Stay calm,” he told himself. He was breathing hard, and that was bad news. The stink of Kali’s last blast still hung heavily in the air, and the faster he inhaled it, the sooner her scent would imprint itself on his brain. Already he could feel those evil chemicals changing him. He now felt, to his horror, a… physical response to her putrid gas, one that only grew stronger with every whiff. It was terrifying how fast his mind was being warped.

 

BBBBBUUUUUURRRRRRRRFFFFFFFFFF

 

But what could he do? Kali’s heavy cheeks squeezed him from either side, locking him in place. At most he could turn his head to one side and hold his breath as the fart thundered past, an effort that made virtually no difference in the amount he ultimately absorbed. He had to inhale sooner or later. And thanks to her practically airtight leather pants, the gas had nowhere to go but his nostrils.

 

After a few seconds he gave in, gasping for breath and gulping down lungfuls of the hot, cheesy air. He gagged in disgust even as his cock twitched, and his brain shivered and tried to tell him he was enjoying it. A voice that was growing more convincing by the minute. “Please, anyone,” he panicked, “get me out of here!”

 

Then suddenly, as if answering his prayers, Kali’s hand came probing between her cheeks. Wrapping her fingers around his waist, she dragged him dazed and disoriented back into the light.

 

“Look sharp, bug. We’ve got company.”

 

From the cold lab bench where Kali deposited him, Max looked up. Five colossal figures stood around the table, ten predatory eyes watching his every move. He’d never been surrounded by so many giantesses at once. And these would have been intimidating even at normal size, each dressed in black clothing, chains or spiked leather. All unmistakably Juno. Max gulped as he took each of them in.

 

Kali he obviously knew. And Ophelia beside her, looking just as she had earlier that day, short, bottom-heavy, and more than a little out of her depth. She wore her usual fishnets and choker, and had an unusual gleam in her bright green eyes. The girl on Kali’s other side was unfamiliar – lanky, unwashed brown hair, heavy black eyeliner and possibly the biggest tits he’d ever seen straining a white tanktop to its limits. The next goth took Max a moment, but when he recognised her his stomach dropped: Vanessa Sombier, one of the most infamous misandrists on campus. Long, neon-green hair framed her ghostly pale face, and her plump black lips were curled in a scowl, like he’d already managed to offend her.

 

Then last, but far from least, was the tall, mature beauty looming over Max with a regal smile on her face and one hand on her prodigious hips. A floor-length black gown hugged every inch of her bulging curves bar her enormous chest, which was all but spilling out on top of him. Her tight corset clenched her waist, accentuating the size of an ass that was already nothing short of gargantuan – so huge he struggled to take his eyes off it, equally as enthralled as he was terrified.

 

“Hello there, little one.” Said Alexandra Ventus, dorm mother to House Juno and granddaughter of the university’s founder. “You gave us all quite the scare.”

 

“I did?” He asked nervously.

 

She chuckled softly. “A lot of time and effort went into the formula flowing through your veins. It would certainly have been frustrating to lose it.”

 

Ophelia flinched. “R-right, um… sorry about that. Again.” She stammered. “I really didn’t know it was that special.”

 

“Never apologise on a man’s behalf,” snorted Vanessa. She shot Max an accusatory glare. “It’s the bug’s fault for wandering off. If he’d just stayed put we wouldn’t have had any problems.”

 

“Well, whatever. He’s here now.” Kali crossed her arms over her chest. “I’ve been in contact with the manufacturer, Hazel. She’s confident that given a sample of his DNA, she can develop a sister formula that’ll have him producing more of the original serum through his 'natural excretions'. Lucky for us, I just so happen to have given him the addiction compound for a fun little side project I’ve got going on. So he’ll be blowing loads to my gas within the next few days.”

 

“My handiwork, by the way,” the lanky girl wiggled her eyebrows at Max. “Hi! Heather Newhouse, chief chemist.”

 

Kali scoffed. “Yeah, and your handiwork left all of our last tinies useless as test subjects, so maybe don’t break an arm patting yourself on the back.”

 

While Heather laughed that off, Alexandra smiled as though recalling a fond memory. “Ah, yes. The poor things.” She sighed. “I understand why the side effects meant we couldn’t continue, but I have missed teasing those silly little men. They way their tiny cocks jumped around when you farted on them was always amusing to watch.”

 

Max listened to the conversation with a growing sense of foreboding. “What side effects?” He wondered. “What happened to the last subjects? And what’s going to happen to me?”

 

Alexandra patted the subtle bulge of her gut beneath her corset. “I rather feel like reliving the past now, in fact.” She glanced at Kali. “May I?”

 

“Be my guest.”

 

Max watched Alexandra give him a sultry smile before turning slowly to present him with her ass. He stared transfixed as her backside ballooned out before him, almost comically large – her curves swelled against the fabric of her black gown, and rippled as she perched herself on the edge of the table.

 

FFFFBBBRRRRRRRAAAPPPPPPPTTTTTT

 

The fart billowed out softly, to envelop Max in its pungent embrace. The older woman’s gas lacked the raw power Kali could punch, though her scent was far more noxious. Fuelled by a diet rich in sharp cheeses and red wines, one whiff was enough to have him squeaking out cries for mercy.

 

“Goodness. He’s an excitable one, isn’t he?” Alexandra tittered. “Brace yourself, dear, I’m afraid I’m not quite done.”

 

“Room for one more?” Vanessa grinned, parking her butt on the table beside her dorm mother.

 

Ophelia perked up, sensing an opportunity to prove herself to her fellow Junos. “M-me too!”

 

Still recovering from the last blast, Max regained his senses in time to find himself now surrounded by three enormous asses. Vanessa and Ophelia were shimmying backwards until their rears pressed together, forming a circle with him trapped in the centre. Everywhere he turned he was faced with a pair of jiggling buttocks aimed at him like cannons ready to fire. “No! Wait!” He shrieked.

 

BBBRRRAPPPPP

 

BLLLOOOORRRRTT

 

FFFFBBBRRRUUUUUUUFFFFFFFFF

 

The women burst into laughter as they unleashed a storm of gas on the poor tiny, and kept him caged in to suffer in their stink. The three combined aromas were too foul for his brain to even process properly. He could only lay twitching in the reeking cloud, retching with every breath.

 

“Damn! I almost feel bad,” giggled Ophelia, looking between the others for reassurance. “Right?”

 

“Fuck, I don’t.” Vanessa smirked. She nodded over at Heather. “You want in on this?”

 

“Nah, I’ll pass.” The lanky girl scratched her hair. “I’m more into receiving than giving. Honestly, I kind of hate that this guy gets to spend all his time shoved up Kali’s butt, and he’s not even enjoying himself back there.”

 

“Enjoyment isn’t really the point.”

 

“Yeah, but still…” Heather brightened suddenly, turning to Kali. “Hey, I know! What if I swallow him? Then I can go back to worshipping your ass, and all the farts I eat will still condition his brain, just from the inside of my stomach. Win-win!”

 

From within the ring of asses, Max looked up in horror. He didn’t know what was worse – the way she suggested devouring him so casually, or the fact that Kali actually seemed to be considering it. But then thankfully she shook her head. “No. I don’t want to risk anything happening to him until we have what we need.”

 

“Aw, come on. You know you miss our rimming sessions!”

 

“I said no.” She snapped. While Heather pouted, Kali reached over the table and plucked Max up into the air. “Anyway, I’d better get the bug back where he belongs.”

 

“Oh, so soon?” Said Alexandra. “I have to say I completely understand your choice of victim, Ms. Kidd. He’s a cute one.” The dorm mother smiled at Kali. “What do you intend to do with him, once the side effects begin to manifest?”

 

She shrugged. “Sell him, probably. Our overseas buyer said she’d be interested if we ever produced any more.”

 

Alexandra hummed. “I recall. Still, I don’t know if we should let Katarina have all the fun.” She reached out and stroked the length of Max’s body with her finger. “Who knows? I may be tempted to keep this one for myself.”

 

Max gave an involuntary shudder as he was whisked away, to be returned to the hot, steamy prison of Kali’s ass. In a strange way it was almost a comfort, knowing he was being put out of her grasp. Whatever long-term plans the older goth was envisioning for him, he was certain they were nothing good.

For Max, the rest of the day felt like it dragged on forever. There were no more breaks. Nothing to distract him from the constant pressure, the sweltering, sweaty heat, the odors that seemed to seep into his very skin… and the endless onslaught of farts.

 

FFRRRRAAARRRRTT

 

Throughout the day he’d struggled valiantly to resist the effects of the addiction compound, but it was a losing battle. With each new wave of stink his will was sapped a little more, while the pleasure response grew stronger. It didn't help that with no water provided the heat forced him to slurp down beads of salty buttsweat as they rolled down Kali's cheeks, just to quench his thirst. Now as the latest meaty blast filled his lungs he found himself, shamefully, rock hard.

 

And then finally, after hours of uninterrupted torture, Kali’s hand came to fish him out of her pants again. She held him up to her face for a good look between his legs, and he saw her lips curl sadistically.

 

“Been enjoying yourself down there?” She chuckled. “We made a good start today. Won’t be much longer until you’re totally hooked. But for now, it’s lights out.”

 

She dropped him a short distance onto a cold, hard surface on top of a lab bench. Looking around he found himself in a rectangular box, surrounded by glass on all sides. A terrarium. “You mean – you’re leaving me here overnight?”

 

“Only one tiny gets the privilege of sharing a room with me, and that’s my darling, dedicated step-bro. Sorry to disappoint.”

 

Max tried his best not to look visibly delighted, though the prospect of a night away from Kali made him so happy he could break out dancing. At the same time, he felt an overwhelming wave of sympathy for the man unfortunate enough to have this tyrant for a step-sister. All the horrors Max had suffered in a single day, this man must have been enduring for years. “Poor guy.”

 

Kali turned to leave. “Anyway, we’ll pick up tomorrow. Make sure to get some rest. I’ll be here bright and early with my raunchiest morning gas.”

 

“Oh, um – mistress! Wait? Please?”

 

She paused. Turning slowly, her cold red eyes rooted him to the spot. “What.”

 

Max swallowed. He’d intended to use this, the first chance he’d had in hours to actually speak with Kali, to beg her to reconsider. Surely there had to be some shred of mercy buried deep down inside her that he could appeal to? But one look at her face now, and he knew he was mistaken. “I, um…” his mind raced. “It’s… cold.” He finished, lamely.

 

For a few seconds she was silent. Her eyes flicked over the empty terrarium, and her smile returned. “Oh yeah? Then we’d better get you a blanket.”

 

Kali kicked off her boots, then pulled down both her pants and underwear. She stood in front of him naked from the waist down, twirling her panties on one finger. Then she flung them across the room into the terrarium with him. The fabric landed with a sigh that kicked up the air around it, filling the tank with the overpowering scent of her ass.

 

“Those ought to keep you warm.” She chuckled. “Sweet dreams, bug.”

 

Max watched her stomp away, flicking off the lights as she went. He was left alone in the dark, a few blinking LEDs on various lab equipment providing the only illumination.

 

Slowly he sat down. He was glad to be away from Kali at last, but still… he missed his own terrarium, with its soft cushions, snacks, phone. He even missed the nights Kaley would have him sleep somewhere on her body, tucked away warm and safe. Sure, it could get a bit smelly. It was still a hell of a lot better than this.

 

Grimacing, Max stepped gingerly into the folds of Kali’s panties, wrapping them around him for warmth. The stink of stale farts and sweat were baked into the fabric, assaulting his nose no matter which way he turned. He sighed as he felt his cock stiffen in response, and drifted off dreaming involuntarily dreams of giant butts, gas, and toilets.

 

Until a sudden noise jolted him awake.

 

Max sat up, rubbing his eyes blearily. It was still the middle of the night, but he could hear the lab door opening. A silhouette was framed in the doorway, light streaming in behind them. "I've got a visitor." But who?
