For this particular idea, I could be travelling through California on a working visa. I could be working at a well known lawyers office or other business that generates a lot of income. Because of a bet between several billionaires, im drugged and smuggled out of the building late one night a fortnight into my employment there and taken to a surgeon, who alters my face just enough, enhances my body, including impants to give me a DD or E cup bust, changes my eye and hair color. While thats happening, im given the life and identity of an adult film star, bisexual perhaps, who does porn and fetish style films, as well as net downloads.
I would be resistant about it when i wake up after a month, to find that ive essentially been 'killed off', and been given a new name and life. I would eventually have to give in and embrace my new life.
If you like this idea, you could play one of the billionares, perhaps the one that recomended me, or the director of an adult film that ive supposedly 'signed on' to do while i was out of it for a month or two.
