Been trying this, and found interesting writing as far as norpo (+18) visual novels go. Good for tragic pasts not involving some kind of sexual abuse, which would have been the easiest path. Ashley's and Maria's come to mind.
Very disappointed with Lin's though. It only goes the way of making her the perfect slave slut. Was expecting something about her eventual manumissio and the struggles of pioneering it in a society where her race is enslaved. After the "slaver contest challenge" came up, I stopped caring about her arc and focused on the rest.
Anyway, commendable work.
