[M4F] Supergirl's Subjugation

Here are a few sketches of possible scenarios:

Overpowered

"So... This is the one they call 'Supergirl'"

My tone is calm, booming, as I step forward towards the figure of the Superheroine. Behind me, with a slow groan, the facade of a building crumbles to the ground.

"Enough! Surrender, now!" She's angry, her deep blue eyes shining with restrained power. An intimidating sight, even in such a pretty frame.

My answer is a calm, infuriating chuckle. "Surrender? I will indeed accept yours..."

In a flash, my hand flashes out, knocking her to the ground before she can react - the first indication that this villain might be truly out of her league...

Tricked

I hear the door clang open, as it's kicked down with inhuman force. Slowly swiveling around in my chair, I take a look back, and smile. Supergirl - just as planned.

"It's over." She announces confidently, stepping forward, secure in the knowledge that my lack of powers can be no match now that we're face to face.

I stay unmoving for one, two instants, letting her approach closer. "What's wrong? No words now?"

I hear your taunt, and then laugh. "You're right, Supergirl. This is over." My confident look must have prompted something in her, and she immediately springs forward, powers propelling her towards me.

But too late.

At a click on my chair, a hidden panel in the ceiling swings open, and a dull green glow bathes the room - kryptonite. As its light hits the heroine, her loss of power, her weakening can be seen clearly.

Instead of slamming into me with the force of a freight truck, it's the impact of a young woman - easily caught, held, overpowered...

Controlled

For the last two weeks, National City had been plagued. A mysterious new villain, executing impossible heists. Guards would swear on their lives that they'd seen nothing, that they'd never left their posts.

Even as videos began to surface, of them willingly disabling the cameras. Walking out into the street, carrying valuables. No one could recall anything.

Today, Supergirl would put an end to it. A trail of breadcrumbs, barely visible, was there. The villain had a pattern. And today... he'd be here...

The heroine landed slowly, watching. Only to whirl around, at a quiet chuckle.

"Finally"

Before she even catches a glimpse of her foe, a pressure is felt on, around her mind. Briefly, she resists, before she can feel her defenses collapse.

"Mine."

If any of these, or the general idea, appeals to you, send me a message with some of your thoughts, kinks, and/or limits!

Of course, this doesn't have to be Supergirl - most heroines (or villainesses) would work for me as well - Wonder Woman, Starfire, Power Girl, Black Widow, Catwoman, Batgirl... plenty of other options there.

My other prompts are always open as well - so if you fancy other setups for superheroines defeated, Game of Thrones, celebrities, or a feminist's submission - go ahead and check those out!

Of note, I'll be off and on about responses for the next few hours - so it's not that I'm ignoring you!
