Hah, the difference in how fast this progresses compared to the novel cracks me up.
In the novel he still hasn't slept with anyone up to this point. The lady on the last page in this chapter is the one who touches the cursed sword and basically the same thing that happened to the princess in the manga happens to her. He has to sleep with her or she dies.
@Dawa That's not how I remember that. If I remember correctly, he doesn't sleep with women if he doesn't consider them to be a "Good woman", he always slept with every-single one of them since the beginning. And it all started with Helen.
