To your delight, the door leads to an important looking staircase with a sign next to it indicating that the exit is that way. You follow the staircase to the top where you open another door and bump into Mistress Stacy again.
"Ooh what do we have here? I don’t believe you have an appointment in Mistress Stephanie's office. But I’m sure we can squeeze you in. If you want to escape the house, you HAVE to pay her a visit. In the meantime I’ll have to keep you busy until we have an opening."
"I order you to suck my high heels and then slowly lick your way all the way up my looooong legs."
A minute later you hear a buzzing sound.
"Oh that means that you can go in now."
