Giantess Orc

You are a human mage in a fantasy world with magic, dragons, elves and of even orca. The orcs are a savage tribal race that love fighting and subjugating other races to use as slaves. You are on a quest in the forest when you duck down seeing a giant orc woman hunting. As you are sneaking away you step on a twig and alert her if your presence. You try your cast a spell on yourself to get out of there but in your panicked state you cast a shrinking spell that shrinks you to one inch tall. The orc woman then catches you and brings you back to her village to use you later. She speaks in somewhat broken english as orca aren’t that smart so maybe you can trick her into freeing you or doing what you want if you play your cards right.
