She pleasures a client.

"You know that I'll escape eventually, right," Blackfire says.
"Sure you will," Kitty replies, "For now?"
"Fine- I'll play your game."

Kitty smiles and runs out of the room.

The Maids fully free Blackfire- hence Kitty's exit- and give her an outfit to wear.

She knows enough about Earth culture to recognize this Slave Girl Costume.

They leave her there.
She sees that the room is covered in mirrors.

Eventually, a man walks in.

"Knees. Now."
'Bossy, eh? I'll play along.'

Blackfire obeys and watches the man strip down.
'At least he's a hunk.'

He walks over to her and pulls her head in for a face fucking!

'Oh, so that is how this is going to be. So be it.'

She uses her Tamaranian body control to adjust to this motion and take it better than most ladies could.

The man has his fun and then puts Blackfire onto her back.
He starts to fuck her and she takes it.

'At least he's a good fuck. He's no Martian, but he's good for an Earther.'

Unbeknownst to her, the radiation weakening her is also making her horny and pliable.
Without the guy fucking her, it wouldn't be doing much.

By the time he cums, she cums with him.

He gets up and she lays there with his (non-potent) seed leaking out of her...

Kitty smiles at how well this is working.
