There's something extra effective about women who are fully clothed while discussing chastity. I imagine the men they are talking to are naked, with their cock cages on display. The idea of a guy having to 'serve' in 'lots of humiliating ways', like in that last cap, offers so many possibilities. Hope you'll detail some of those humiliations.
I always like finding pictures of girls who are fully-clothed, because there is such a lot of scope for stories, especially ones where she is not the keyholder. I try to look at them and think what they might be saying.
