While you were being carried by Gracie, you watch as she opened the door to the supply closet, and brought you in there before closing the door, and locking it behind you. Once the door was locked, Gracie looked back at where you were sitting at, and when you stood their frozen, you see D.C's sister raise up her t-shirt to the top of her breasts.
T.V: What is she doing?
D.C: Practicing.
T.V: For what?
D.C: You'll see.
"Let's see if I can do this right," Gracie says, and crawls over to where your exposed pussy was, as she wrapped her arms around your mannequin like legs. Just then you felt Gracie's tongue dig into your pussy, as you continue to not emote at all, and not make any sounds along with that like most mannequins would do. You didn't think this girl would have to do this, but at least the entire closet was secure enough with Gracie locking the door to it, before starting with the sex.
