It's Just For the Money, Right? (Twincest, female needed)

[Hunter]

I've just gotten this idea.   A teenager finds that he's a little short of cash and really doesn't do well with finding or keeping jobs.   He's stumbled across a way to make good money and fast: in the porn industry.   The only problem is that he has to convince his rather meek twin sister (i.e. submissive) to go along with it.
