Close the door and wait

You sit on the stool and wipe a stray drop of cum from your cheek. You wait if a new dick would appear through either of holes on the walls, but nothing happens. You realize that you have no idea how this all is supposed to work. Sure there is a light outside of your booth indicating that you are in there, but you can't hear anyone else moving in the room. Are you supposed to just sit there and wait, or should you somehow advertise that you're willing to suck?

After all, it doesn't seem to be that crowded here, so it might take a while before anyone new appears.
