I Do Not Own Inuyasha.

Prologue

All full-blooded demons had a moment similar to that of a half-demon, a moment of complete and utter weakness. A moment where all their guarding walls fell and they became vulnerable to the temptations of the world. Whereas this point of vulnerability was not as frequent as when half-bloods are rendered mortals, it is seen as a bigger problem than human half-bloods. See, when these times arrive, the demon is pulled into a stage of lust, and that is solely what drives them. Their hunger for pleasure drives them to do things they wouldn't normally do. And this was a problem, for anything could happen when you weren't in control. Anything.

Because of the animalistic behaviors displayed by demons during these points, they have been thus dubbed, heat. So, when demons are in heat, it would be best that humans and other demons alike be cautious of where they go. For if a demon couldn't find a willing participant, it would have no problems with forcing someone to satisfy their needs.

One couldn't simply run off when the time of heat came, for there was no pattern to the times when a demon went into heat. They were so sporadic and spontaneous, that was one thing that made them even more dangerous. At the most, a demon felt some sort of warning a few hours before their lust overcame them. Like the scent of the opposite sex becoming slightly more prominent, such a simple warning. Some smarter demons choose to quickly satisfy their thirst, whereas other, more foolish ones, thrash around in a panic until it is too late to take action.

This is why, in some cases, though it is never said aloud, some demons view half-breeds as lucky. Because of the human blood coursing through their veins, they never truly experience the temptations full-blooded demons have to endure during heat. True, they may have their time periods where they are nothing but worthless humans, but having that does not hold the chance of unconsciously doing something with horrid consequences, like marking a mate for example.

Marking at random was not something that is suited well with more refined male demons. It may go well with barbaric demons to have some random mate, because their mate can no longer leave their sights, they are no longer allowed to roam free. Of course, the male is content simply having someone who has to willingly bid to their demands.

Greater male demons prefer to choose their mate a bit more carefully. Their choice will affect their whole families and those around them. It is a very serious thing. That is why, especially to royal demons, heat is a very dangerous thing that must quickly be restrained and taken care of. Demons with royal blood cannot simply let their inner beast run wild, claiming some random demoness as their property. It is practically taboo.

So, for demon lord, being in heat is something that must never be taken lightly; either you restrain the urge, or atone for the mistake you have made. And luckily for a certain silver-haired lord, his time of heat was approaching at an almost alarming pace. And he'd be damned if he had to atone for something so petty.

A/N - I apologize for shortness, but this is only the prologue. It'll be longer next time, I swear. I'll try and stick to the whole, "Update once a week thing," but I'm very sporadic with my updates so you never know. This will not be a very long story, probably staying under six chapters though, okay?
