My character sees an ad for an overseas job teaching English overseas. (Country is open to discussion but I will use Japan just as an example here) I inquire about the job and it is to teach English to children of businessman/businesswoman in Japan for a very good salary. I get the job and fly overseas from USA. Once I get there I find out the "job" is actually quite different. My purse and passport are taken from me and I get transported to a remote home in a very rural area. I am the one getting taught there, as I am not the teacher. What I am learning is how to make myself attractive to someone interested in a slave.
That is basic idea. I am open to discuss any ideas you have for the story. Please PM me with any questions or if you interested in doing this as a role play together.
