Every way you choose!

For starters, you make the partially-bound and powerless Power Girl ride your cock.

You sit down and she has to do all of the work.
This makes her show her true submission.
After all, if she just laid there and you fucked her, it is not the same.

She has flashback to when she first had sex with Captain Marvel.
Bobby was just hitting puberty, so his actions in his other body were quite...excited.

You aren't 'The World's Mightiest Mortal' (Google it), but you do alright.

The bondage and role-playing even things out for her, making it even more fun than normal.

Not content with just one position, you decide to try out as many as possible.

She has another orgasm in the Reverse Cowgirl position as you fondle her tits.
She cums again as you pound her like a Screwdriver, with her head against the ground.

Eventually, you give her what you know she wants- Doggystyle.

As you make her cum again, you wonder if she has a good story about this position.

She does, but she won't share it anytime soon.
Part of her initiation to the Team involved going on a Mission with Hawkgirl.

After they beat Tattooed Man and Black Hand, they had some fun with Hawgirl in the dominant position...

Good times!
