Blackfire has fun...until she doesn't.

Unaware of Kitty's plans, Blackfire decides to keep playing with the Titans.

Raven has her bondage changed a bit to have her legs tied to each calve touching each thigh.
She adds some rope around her toes and runs it to the gag, forcing her feet to be bent back.

Helpless, she is woman-handled by the villain and placed in what looks like a simple, metal closet.

With the press of a button, however, the gravity in there is negated.

She also removes the bikini, which is quite easy with the strings, and leaves her there in the dark.

The second part of her plan involves taking the broken and pliable Starfire to the same room.

Fully naked once again, she's tied in a matching manner and given a matching ball gag.

She's surprised when her Sister takes her to the 'closet' and opens it to reveal Raven.

Things get worse when her body is pressed right up against Raven's and bound around the stomach, pressing their breasts together!
She presses a button on the gags and they merge into one.

As a final humiliation, Raven's hands are freed, but then placed on Starfire's tight ass and tied with a loop around the back, keeping them there.
Starfire gets the same treatment and Blackfire admires her work.

"See you tomorrow, sluts," she says, closing the door.

She's surprised to turn around to see Kitty standing in the doorway.

"Nice work with those two. Now let's do some more business."

Blackfire is confused, until one of the large rocks that weakens her people drops from a hole in the ceiling, right into her arms.

Kitty pulls out her ray gun and blasts her with it, doubling the effect to quickly immobilize the villain.

Her eyes can barely focus and she is pretty much drooling as two of Kitty's Assistants enter the room and take her away.

When she wakes up, she immediately tests her bonds and looks around, as much as she can.

Arms tied to her chest.
Ball gag tied in tight.
Legs tied together in single leg sleeve.
Hanging from some sort of contraption (to remove any leverage).

Kitty is sitting several feet away with a smile.
