This world is nearly identical to our own in every way except one. It is possible to comit yourself to an unbreakable vow. Nobody quite knows how the vow works. But we know that is it is properly made then the maker will die instantly if it is broken. It cannot be made by coercion but the rules about what xonstitutu

You are a normal woman who lives a typical north American/European lifestyle. You have an okay job and friends. One day you decide to go on a girl's trip to a rural area to go hiking and stay in a cabin. You make a near fatal mistake of traveling into a cave with your companion. You don't know much about cave exploration but it looks safe. Suddenly you hear rain on the roof. You turns and see water rising. You run into a chamber and you don't realize that it is filled with carbon monoxide. You pass out. For the next several hours you and your friend stumble around intnhe dark after your flashlight gives out. You are feeling desperate when your friend passes out one more time. Suddenly you see a light approaching. You tell. I come with survival equipment and oxygen to save you. I saw your vehicle and being an experienced American amateur cave explorer inknew how to help. But before I do I have a catch.

I will save you and your friend. However you will need to make an unbreakable vow to me that you will come and submit to me as my slave for all eternity. I will give you three months to get your life in order. If you tell anyone about the agreement you will die. If you attempt to escape slavery in any way you die. In exchange I make a vow to save your friend (who will go free) and yourself who is condemned to a life of slavery. You can have a minute to decide before I leave you both.

Looking for intense roleplay concerning intense coerced semi voluntary slavery plot. Please be able to verify that you are female.
