She's prepared.

"We're here," Cheetah says, glancing out a window.
"Time to knock this one out," Giganta says, "No reason to spoil the surprise. Now be a good slut..."

She approaches Wonder Woman with a chloroform-soaked rag...

In her temporarily powerless state, she can't fight this.
She can't stay awake.
She passed out.

Giganta easily carries her inside.

She hands her off to two men, who bring her body into a padded room and set it on the floor.

They check her bonds and make sure that she is secure for what comes next.

Did they have to pull her tits out? No.
Did they? Yes.

The final preparation involves her being forced to stand up.

They prop her up and tie her bindings to the ceiling.
There is no escape now.

She wakes up too late and struggles.
She spots a camera and is shocked.

Wonder Woman is left to struggle for the next few minutes.
She needs to know that there is no escape.
