You start trying

You and Hermione start working your way to the door. When Filch suddenly looks around. You hold your breath thinking he must have heard you or Hermione.

Mrs Norris is still on the table licking cum off of it.

Suddenly Filch lifted the cats tail and tossed some dust on her rear end. With in moments the cats pussy was large enough for a human to fuck. Filch did not waist a moment he picked the cat up and rammed his into her. He just stood there and fucked her.

You and Hermione just walked out at that point.

Now all you needed was some where you could read the book in piece.

The room of requirement would be perfect.

You and Hermione quickly arrive and walk past it three times and the door opens.

The room shapes its self to suit the needs of the person entering it.
