I'm trying to find an old hentai, set during the medieval times. A girl, I believe with wavy blue/green hair is about to be sold to slavery. A man buys her and for some reason she thinks she is saved and that he is a good guy. But then he rapes her. Some torture involved too.
There's one scene where she's crawling away naked but he just penetrates her directly.
Image is not related, although the art is similar. I'm not sure if there was a second episode with a second girl.
