of your works this is the one I liked the least. even if it is a continuation of the previous one the story is poor and sometimes confusing... I hope that it improves in the continuation. I noticed that your female characters are all taken from hentai anime. If you still don't know who to choose I suggest Angel Blade. if the story changes halfway through like you did in your first works, I think it will attract more... you could create a first phase of struggle, defeat and sex, a second phase where the protagonist seems to react, second defeat and sex...
