Infiltration

Natasha went first as the pair of Avengers approached the side door of the bank. She glanced back to make sure Wanda was still right by her, then quickly tugged open the door.

They went inside, to a plain white corridor.

"Service entrance," Natasha said, "she might not even know it's here, so we can get the drop on her as long as we're quiet." They proceeded down the corridor, dual squeaks from their straining leather outfits putting paid to that plan.

"Maybe we should take our clothes off." Wanda suggested.

"I don't like the idea of going up against a superstrong villain, naked." Natasha replied, "But this isn't ideal." She looked around, "I have an idea. Give me a boost up."

"Where?" Wanda followed Natasha's gaze to an air vent on the wall. "Ah."

Wanda backed against the wall and held both hands out, Natasha stepped up on her hands and stretched up to the vent. She lifted up the grate and began to wriggle inside.

"Uh-oh." Her voice was muffled by the top half of her being in the vent.

"Uh-oh what?"

"This vent is a little smaller than I expected."

"Or you're a little chubbier." Wanda muttered.

"What was that?"

"I'll give you a hand."

"From down there?"

"You do remember I can move things with my mind, right?"

Wanda moved her hands slightly, a ball of glowing red energy formed directly behind Natasha's wriggling buttocks, then slammed into the spy's plump rear.

RIP!

"What was that?!" Natasha's voice was worried, she dreaded what Wanda could see for certain- the seat of her catsuit was torn open to reveal an expanse of pale pink skin. If she was wearing underwear, it could only be the smallest of thongs.

"Er... Nothing." Wanda replied, forming another ball of energy and pushing against Natasha's behind harder this time, sending her the rest of the way into the vent.

"Ow!"

"You're in." Wanda said.

"Yes, I noticed." Natasha's voice came back, "I... Oh no, my suit!"

"Sorry about that, but it was on the cards anyway."

"Whatever. Are you coming up here?"

"You know, I think a two-pronged attack might be the way to go."

"Fine, I'll see you at the vault."

"Roger that, Black Widow."

As Natasha made her way crawling through the vent for a stealthy approach, Wanda continued up the stark corridor alone.
