I have been thinking about another chapter, but haven't quite gotten a story into my mind just yet. Though it may just be a one-off thing (meaning it might not really be all that tied into the previous entries.) Also, I may eventually return to this series and redo them all, much like my Final Fantasy stories (which I encourage you to read.........please :P)
As for the Riza story, I tried to play on the fact that she does have a rarely seen playful side, while the lovely markswoman is always serious and hard nosed in most situations, I would think she might have something of a 'wild side'. Perhaps she wouldn't be into messing, maybe she would, you can never really tell how kinky some people are.
Thanks for the review.
