This story has a good start. I like the sound of it but sometimes it's a bit hard to understand or read it. Some sentences are long and it makes me pass them. It's because it's long sentence after long sentence. There are some small typing errors but that's fine, happens to me too. 
I do hope you know that Asmodeus is indeed a demon and he's actually the demon prince of lust. I'm looking forward to see what you're going to make out of it ;)
