Yes

"I-yes, yes I accept," you respond without hesitation. The dragon nods.

So be it. The contract is complete, bound by ancient magic. To complete it, we must speak our names.

I am Nightwing.

You follow its lead. "I am Peter Resignor."

First, we will go to your mother, as I fully intend to uphold my side of the agreement. To go there, so close to human civilization, I will need to take a more suitable form - one that I will be adopting henceforth in my attempt to assimilate into humanity.

"A more suitable form?"

Suddenly, there's a blinding golden light. You have to shield your eyes, or you feel like you'd go blind.

When the light finally fades, and the sunspots in your eyes are no longer too intense to see through, you're able to see that the dragon has disappeared, and has been replaced with a woman. She still glows with energy, enough so to illuminate the darkness of the cavern and allow you to see her form.

Her skin remains the same absolute black as the scales of the dragon. By the way they shine, you can tell that her skin is actually made of scales.

"Whoa..."

Her eyes open, and you can still see the brilliant golden sparkling of her eyes - the same as they were when she still held the form of a dragon.

Her body plan is almost completely humanoid, with the exception of an addition of a tail, and a set of wings sprouting from her back. Interestingly enough, her face still holds some reptilian features, but if it weren't for her black scales you'd be hard- pressed to consider her face anything but human.

She now also has shoulder length hair, and it seems to be quite beautiful - it shines an illustrious white, in stark and amazing contrast to her skin tone.

It's also rather apparent to you that she has adopted some of the...finer details of a human woman.
