Curious

"Okay...I have a few questions."
"I figured you might. Let's start with the obvious- this is Jinx.
She's not a Villain anymore. She wants to be a Hero like you and Star."
"...and she's blindfolded and gagged, why?"
"Well," you explain, "The blindfold is just because we can't fully trust her yet.
You know, in case this is some long con to get Security Intel."
"...and the Gag," Raven continues.
"That was actually her idea. In fact, she insisted."

Raven gets closer to you three and touches Jinx on the shoulder.

"Did you really?"
Jinx nods vigorously.
"Jinx is really the Submission," Starfire explains.
"It's submissive, dear," you correct, "It's what Bumblebee was earlier today, right?"
Star nods.

While she can't speak, Jinx now makes a mental note to ask about that point later.

"So let me get this straight- she wants to be a Titan. To prove herself, she let you blindfold her before taking her to the Tower...and insisted that she be bound and gagged too?"
"Pretty much."
"Did she ask for the strap-on cock too," Raven asks.
"That was our idea. She's a gift for you. Being The One isn't a, well, one way street," you explain with a smile.
"I love the initiative, I really do. I just wasn't expecting, well, this."
"We'll tell the others tomorrow about Jinx wanting to join the team and we can fix up one of the temporary holding areas into a bit of a normal room. She can stay there until we all decide otherwise. For now though, she's all yours."

Raven calls out her magic words and Jinx's clothes disappear, reappearing neatly in a pile on a dresser across the room.
The ropes, blindfold, gag and strap-on stay, of course.

Jinx shivers slightly due to the sudden exposure...and from excitement.

"Let's have some fun then," Raven says, grabbing Jinx's nipples and leading her to the bed.
