A Seat for Scarlet Witch
by AnUnturned

Scott winced painfully as he sat onto the sofa in the break room of the Avengers facility. He was supposed to be relaxing, but this room (as well as his aching body) made it difficult; both served as constant reminders of his misadventure under Black Widow just a few days ago.

As if being sat on and farted on wasn’t bad enough, when Natasha had discovered him stuck to her butt she was (admittedly, understandably) furious. She had given him an ass-kicking that left him sore even now – although, given her reputation, he’d probably still gotten off light.

He shook his head, trying to forget that whole ordeal. “Maybe some food will distract me,” he muttered to himself, as he opened his lunch bag to find… a taco. He grimaced; it looked delicious, but now all it made him think of was Natasha’s gas. “Ugh… maybe later.” He sighed. Suddenly he heard the door open, and looked up to see another Avenger approaching.

“Oh, hey Wanda,” he greeted her.

“Hey Scott,” she replied cheerfully. Wanda Maximoff, the beautiful and powerful hero known as the Scarlet Witch, walked over and sat down next to him. “How’s it going?”

“Yeah, not bad. Just, you know, taking a break. Here. In the break room.” He tried to sound casual; he didn’t want anyone to know what had happened.

“Really, you’re fine?” She asked with a strange glint in her eye. He nodded cautiously. “Huh, that’s surprising. I mean, since you got caught feeling up Black Widow, I’m impressed you can even stand!”

He groaned loudly while she laughed at him. “She knew! Aw man, Natasha must have told her,” he realised. He had to try and explain. “Listen Wanda, I promise I wasn’t feeling her up! The whole thing was just a big mis– “

“Don’t worry, I’m not going to tell anyone,” she interrupted him.

“Oh… well, that’s great, thanks, but listen – ”

“I just want to make sure you’ve learned your lesson. After all, we don’t want you pulling any more stunts like that, do we?”

“…Huh? What do you mean?” She didn’t respond, but held up a finger, glowing red with magical energy. A small beam shot out and hit a button on the belt of his suit, and before he knew it, he was shrinking!

He gasped as he was reduced to around 1 inch tall, standing on the sofa cushion where he had been sat a moment before. He pressed his belt again but there was still red energy surrounding it – he couldn’t grow back!

“There we go! Since you like feeling up women’s asses, I’m going to give you exactly what you want!” She stood and bent over, showing him her wide dress-covered butt. She gave it a slap, sending ripples across her thick cheeks. Scott did not like the idea of being buried under them.

“Of course, you may find it’s not a pleasant place to be, especially after I’ve had such a big lunch…”

“Wait, Wanda!” He cried out, panicking. “This is all just a misunderstanding! Let me expla – ”

“No more talking from you.” With a snap of her fingers, little red wrappings appeared and wrapped themselves around Scott’s body, binding his arms and legs and covering his mouth. In an instant he was bound, gagged and helpless to stop her.

She crouched down for a better look at him, a playful grin spread across her face as it filled his view. “Do you want to know what I had for lunch, Scott?” She asked softly. “I had a big plate of sauerkraut, with a ton of beans. And to be honest, I need to fart pretty bad. Do you want to smell my farts?”

Scott gave out a muffled scream and shook his head, but her smile only grew wider. “Oh, but I think you should! Come here.”

She turned and began to sit slowly, letting him get a good view of her shapely ass before it descended to crush him. He could only watch, despairing, as her red dress-clad butt grew and grew to eclipse his entire vision, so close he could feel the heat radiating off it – and then it landed. That familiar incredible pressure squashing him into the sofa, her crack the only place he could find any reprieve from the overwhelming weight, and that subtle earthy scent. For the second time, he had become a seat for an Avenger. And just like before, he could hear an ominous gurgling from somewhere above…

Pffffffffft!

Scott began to gag uncontrollably as a burning hot silent but deadly sprayed his body, bringing tears to his eyes. It was beany and sulphuric, and somehow even worse than Natasha’s! He wriggled around desperately and tried to beg for mercy, anything to get away from the stink.

“Ahhh, ha ha! That felt good to get out. A little weak, but I guess it’s a good introduction for what’s to come!” She giggled as she felt his tiny struggles beneath her, almost imperceptible under her massive rear. “Aww, you don’t like it? But you love women’s asses! And this is what asses do, Scott, they fart!”

Bbbbbrrrrrrrrrrrrrrrrraappppp

“Ooohh, now we’re getting started.”

Her first fart hadn’t even left his nostrils and now another one was blasting him in the face, the sheer force of wind blowing his hair backward. This one was much more powerful than its predecessor and carried with it the raw stench of meat and onions; he could practically taste the gas-inducing meal she had loaded up on earlier, apparently for the sole purpose of torturing him.

“Is that smelly, Scott?” She asked him rhetorically, crossing her legs and squeezing out another short toot. “I hope it is. I want to engrain this nasty odour into your mind, so that from now on whenever you see a woman’s ass, all you’ll be able to think about is how bad her farts must smell! Then you’ll think twice about wanting to touch them.”

Fffrrrrrrrrrrrrrrrrrrttttttttttt

Scott wanted to cry. Not just because of the poisonous gas that flowed non-stop up his nose, but because of the sheer ridiculousness of the situation. “How is this happening?” He wondered. “How can this be happening to me again?! I can’t take it! I’ve gotta get out!” But escape was sadly impossible; all he could do was lie there and suck up Wanda’s farts until she decided to let him go.

Prrt!

Wanda continued to sit on, gas and tease Scott for another fifteen minutes or so, delivering some farts so rancid she almost felt sorry for him – until she remembered she was teaching him an important lesson. Unfortunately, the lesson was cut short when she felt a vibration on her wrist, and glanced down to see her Avengers communicator was receiving a message.

Scott almost cried with relief as the great pressure on his body began to ease, and he saw light again, as Wanda finally raised her ass off the sofa. He took deep, grateful breaths of the (relatively) fresh air and prepared to launch into an impassioned speech of apology, but she began speaking before he got the chance.

“Bad news. I still have a lot of farts for you to sniff, but… duty calls.” She showed him her active communicator. “The team needs me for a training exercise, and I can’t exactly show up and fight with a shrunken man in my ass.”

“No, this is great news!” Scott thought he was off the hook, and gave silent thanks to any gods who might have been listening to his prayers – but unfortunately, Wanda wasn’t done with him yet.

“Don’t celebrate too soon, ass-lover. I recently learned a very useful magic spell, and I’ve been waiting for a good opportunity to test it out… Looks like I’ve found my guinea pig.” She raised her hand and it began to glow once again with that strange red energy. Then she pointed at him, still immobilised on the sofa, and the mysterious red aura slowly began to envelop him!

“Hey, what are you – mm?!” Halfway through his protest, Scott was interrupted – or rather, he had lost the ability to speak! In fact, his whole body felt weird. He felt oddly soft and silky, and he couldn’t move, or even feel his arms or legs. It wasn’t until Wanda picked him up and showed him a pocket mirror that he realised the awful truth; she had turned him into a pair of panties!

“Impressive, isn’t it?” She asked him gleefully. “I can completely transform your physical form, while preserving all of your senses! Which, by the way, I’ve localized just here on the seat.” She smirked and gave him an evil wink. “Shall we go try you on?”

Scott's fearful scream went unvoiced. Wanda took him into a nearby bathroom for privacy and quickly pulled down her old panties, excited to don her former teammate. In his new shape he was helpless to resist as she stepped over him and drew him up, yanking him up toward her gigantic looming booty. He stared hopelessly at her giant twin cheeks, racing powerlessly toward them until –

“Hm, not a bad fit. In fact, you’re pretty comfortable!” Wanda giggled, checking her new panties out in the mirror. “How do you feel, Scott? Are your senses working OK?”

Sadly, they were. He was completely aware of his surroundings, and they stank. The stench was incredible, a deep, bitter, earthy odour that encompassed him completely, and he was wedged up right against the source! Her butthole was directly in front of him, puckering dangerously as though eager to release more gas. And as if on cue…

Fffffppppppppppppppppppprrrrrrrrrrrrrrrrrttt

He thought her farts were bad before – now, they were diabolical. When he had been human, he could at least hold his breath at times, or turn his head away; now he had literally no choice but to slowly ingest the entire rank cloud, smelling and tasting every last particle with excruciating meticulousness. Not a trace escaped his absorbent new body, which forced him to deeply savour the entire shitty aroma. If he was able to vomit, he certainly would have.

“Wow, I can’t smell a thing!” Wanda exclaimed, thrilled at this unexpected benefit. “This was just going to be a short punishment to teach you a lesson, but if you’re this good at absorbing my gas… who knows? This could become a full time gig!”

With that she laughed and set out, ready to engage in a long, physically demanding training exercise. She knew she was likely to work up a lot of sweat, and she still had a lot of wind from her huge lunch to pass; but she set out with confidence, knowing her new panties would easily absorb it all.

Meanwhile, Scott began to despair in his new form as he sucked up yet another greasy blast, his entire being consumed by the stench of digested vegetables. A few minutes ago he had been a human, a heroic member of the Avengers and defender of humanity. Now, he was nothing more than a piece of fabric, wedged up between Wanda Maximoff’s smelly ass-cheeks.

“…But surely she’ll let me go soon, right?”

Sspppppppprrrrrrrrrrrrbbbbbbbbbbbbbbbbbbfffffffffftltlltlllt
