You feels like you're playing on something soft, a good bed even though you don't remember how. As you slowly open your eyes, you can see him, sitting next to you naked while reading a book.
He noticed you're awake, as he closed his book and speak to you with cool tone.
"Oh? You're finally awake, Sleepyhead."
You can see his back have lot of nail scratches, and you can see your own body have lots of Hickey marks. You just remember everything, yesterday you're asking him to give his child, but you refer to his daughter.
After that he takes you to his room, and everything have been blurry since then. But you know what happened, knowing these marks on your body. He gave you lots lots of child inside you instead, and you know he's doing it on purpose.
Arathos is a Demon Lord, and you're a Woman hero that defeat him in the war between Humanity and Demon five years ago. Since then you two have friendly relationship, until now.
