A/N: My wonderful reviewers. I have been directed to a site by my lovely reviewer Lap and I stumbled across the most interesting challenge and could not resist answering it even though I am not a part of the web site from where it originated. I have not gone 'madder' I will attempt to make this one quickie fic cuz I don't want to be working on five stories at once and I will hope no one turns me in if this gets too heavy. Hehe. Oh and my new motto…'Plot? What plot?"

No profit was acquired from the writing of this story nor was any malice intended in any way, shape or form to the author or the actors/actresses who so brilliantly have brought them to life. Though I wouldn't mind shagging um. I did NOT say that.

The Potters had once crossbred with incubi, generations ago, and the heredity of incubus has been lurking in the bloodline ever since. Now just Harry's luck, the dormant incubus gene has awakened inside of him.

An Incubi, is a species of rare magical being that feed on vitality. They send out magical pheromones to lure humans - muggles, witches and wizards alike - and when the victims are close enough, they will hypnotize them and make them climax by magical technique - while feeding on their vitality. A few of the victims might become addicted to this process, and turn violent.

Incubi only have one mate in their lifetime, and only really have sex with their mate, so they are protected and possessed. They have focused magically abilities. They are also so sensitive about their mate's mood and feeling it's near telepathic. When they're 'interacting' with their mate, they will make their mate more vigorous and strong - whether physical or magical.

Rules: Harry's life mate should be a Slytherin - the options include Voldemort, Severus, Lucius, Draco and Blaise - and his victims could include all the male characters and maybe female. Voldemort, Severus, Lucius, Draco and Blaise... At least one scene in which one pair of them fight over Harry's affection and attention. Watching them disrupt each other by stealth is most entertaining. Or seeinganyone in denial of the attraction.

INCUBUS HEREDITY

Chapter 1 Stalker or Stalked

Harry was sitting at the head of the Gryffindor table with the other seventh years by now feeling quite confused. His newly keen senses were screaming at him that something was wrong. For some reason though it didn't bother him exactly. Just made him feel self-conscious.

'Why IS everyone staring at me?' Harry chanced a quick glance back down the length of the side of Gryffindor table he was on. And met up with the eyes of every single person at the table all of whom immediately looked away with looks ranging from shocked to flushed trying to act like nothing had happened. He glanced at the other side of the table and the same thing occurred. Even with Ron and Hermione who were sitting across from him. Harry frowned, something was definitely up and it didn't feel like something as simple as a smudge on his nose or something silly.

Not really paying attention Harry looked up and let his eyes drift over the other three school tables and he froze sharply at the hundreds of eyes staring back at him.

'Okay…ten on the freak-o-meter.' Harry watched as the noise level rose everyone turning to the person next to them to chat about some nonsense. And far over at the Slytherin table he could see one person still staring at him avidly, though they looked in shock. Harry's eyebrows furrowed and Draco suddenly started as he realized Harry was watching him gawk. He immediately gave Harry his patented sneer, which came off a lot weaker than usual, before turning to Blaise Zabini who was next to him shooting looks at Harry too.

Harry's eyes moved back across the tables and again the other students were suddenly NOT looking at him and carrying on conversations. Though he did notice a few people here and there that hadn't turned to get a cover up partner fast enough looking quite lost as they flicked their eyes anywhere but to Harry. And he gave Gryffindor table one last look and the same thing happened. Harry sighed and looked over to Ron to comment on the strange behaviour of everyone and…

'Dear God.' Ron's eyes widened as he blushed red and turned to Hermione, starting to babble about Quidditch. Harry suddenly very badly wanted to go back to the dormitory.

All through the Sorting and the Welcoming Feast Harry felt eyes boring into him and by the time he had finished eating what little he could force down he wanted to be away. Far, far, far away. Harry knew what that scent that had tickled him before but hadn't quite bothered was now. And he was bothered. It was lust and the Great Hall was drowning in it. Harry shallowed his breathing because it was making him slightly giddy.

Harry really wanted to speak to Dumbledore but could he bother him on the first night back and all? He had to find out about how he could hear and see and smell so precisely and why everyone was staring!

Harry tore his eyes away from his barely bothered plate and looked at the staff table ruefully.

'Merlin…kill me now.' Harry looked along the staff table quickly and found every pair of eyes there on him. All didn't look quite so taken with him and for that he was grateful. Dumbledore was looking at Harry thoughtfully. And Professor McGonagall looked quite confusedly around the Great Hall at all the students staring at Harry before coming back to him, so he shrugged. Professor Flitwick, Sprout, Madam Pomphrey, Sinastra, oh God Hagrid, even Hagrid and REMUS Harry panicked in his mind, were all looking at him appraisingly. Harry wanted to scream and run out of the Great Hall hoping it was a nightmare and his eyes ran back over the staff table hopefully. And finally met the black tresses of Professor Snape eating slowly not looking up. Harry was confused, slightly relieved but still confused. Why wasn't HE staring at Harry? And almost like if he'd heard Professor Snape looked up and he frowned. Harry did a double take mouth dropping open. Frowned!? Snape doesn't frown! He leers, sneers, smirks…he doesn't frown!

The hairs on Harry's neck rose and he shivered looking back at his plate.

'I take it back. You don't have to look just please go back to eating…please?' Harry didn't have to look up to know dissecting coal black eyes were roaming him and he wriggled closer to the table on the bench. He suddenly felt naked and a light rosy blush rushed over his face. This continued for a few minutes, Harry's mind overrun with confusion and a desire Harry didn't know how to fulfil. When he wasn't covered in goosebumps anymore Harry knew it was safe to look back at the staff table and he met Dumbledore's eyes pleadingly.

Dumbledore gave Harry a slight nod and as he stood the noise in the Great Hall stopped immediately. It took all Harry's willpower not to run out and he forced himself to walk normally only allowing himself freedom after he was out the doors.

Harry had hid himself behind the hangings around his bed and was snuggled into the sheets pretending to sleep. He listened to the four boys entering the dorm noiselessly and froze. He waited a few minutes after all sounds, besides breathing, had stopped and stuck his head out of the hangings. The other four beds in the room also had the hangings drawn on them and Harry sighed softly in relief. He sniffed lightly and felt his stomach protest. Harry pulled his head back in as his temples began to throb. He smelt confusion and self-disgust and mostly lust rolling off the other occupants of his room. Harry rested his aching head onto his pillow lightly beginning to despise his new gifts. But he could also feel himself and Harry was feeling…hungry. His still protesting stomach was telling him there were four snacks outside and he wasn't eating. Harry pulled back his hangings and sat on the edge of his bed. He knew what he had to do to his friends…he was sorry but he was so hungry.

Harry stood and stalked over to Ron's bed soundlessly and pulled open the hangings, slipping in. He started the process slowly, the hardest part being waking Ron without doing something drastic like smacking him, before hypnotizing him and feeding. Harry slipped back out of the hangings and waited until Ron's harsh breathing slowed and deepened, sure he was asleep again. He then repeated the process with the other three boys in the room before climbing back into his bed sated. And the only person who would know something strange had happened in the castle during the night, without thinking it was a dream, gasped raggedly in his bed as his fourth involuntary orgasm for the night faded away. 'Hell that was…almost like being…seventeen again!' was his last thought before he just about passed out.
