This is something I have been wanting to try for quite some time now, but have not found the right story yet.
I have not come up with much of a plot yet, but definitely want something more than just sex.
My current thoughts are:
1) My character purchases 2 slaves -- would require 2 sub female characters.
2) Husband & wife purchase a slave or kidnap a victim -- would require 1 sub female other could be either.
Plot and setting can be worked out with interested players.
