From 2D Market:
From the master of hardcore doujinshi comes another dark story.
In a patriarchal medieval settings, a single woman tries to live as a strong warrior who needs no man. But most men in such settings just want to see women serve them.
One such man captures our heroine, Charlotte, and puts her through a hell of carnal desire. How long will she resist the temptations of flesh and will her comrades manage to save her in time?
