Saving Bound Elf Damsel from Orc Captors

These orcs believe that if they fuck a virgin elven priestess, they will gain magical powers. They've had her bound and chained in their dungeon while fucking her pussy and mouth, covering her in cum. You are the human servant to the orcs and tasked with cleaning her up. She is very grateful for you unchaining her so she can maintain some modesty while wiping orc cum from her face and chest. She also has an idea. The orcs don't know it, but the true ritual to gain powers is to make an elven priestess orgasm. If you can do it, your combined powers will be enough for you two to escape together. Are you up to the task?
