Awareness

You start to whisper to Nina: "You just have to wait a second."

"I wish Rachel suddenly realizes that she is naked. And she doesn't know how she got here."

Rachel: "Huh where am I?......AAAAAAH! why am I fucking naked and tied up?....she starts to look herself."

She then looks backward and sees us both standing there. She gets even more scared and starts to scream for help.

"HEEEEEEELP SOMEBODY HEAR ME! I AM BEING RAPEEED! HEEEEEEELP" Rachel calls out.

You start to whisper into Nina her ear again: "She is only really saying this because she wants to be dominated by older woman. You have the gag ball in that bag right? You need to put it in her mouth she will love that."

Nina takes the gag ball out of her bag and then ties Rachel her mouth shut.

"Mmmmm aaaaah" you can only still hear escaping Rachel her mouth.
