Chapter 1.

When he first saw him, in the dinning hall, smiling at his friends, he saw her. He saw her in the eyes, in the smile. Snape's heart filled with wretchedness and regret, but these feelings didn't last long. Harry Potter was so much like his father as well in his hair and jaw line that those feelings of love and guilt leaped to anger and hatred. That child was the symbol of all his unhappiness. Looking at him brought up only memories of past torments and mistakes. He could not look at him without feeling pain and so started years of mutual dislike between Harry Potter and Severus Snape.

Harry was unaware of the feelings his presence called. He only knew the way Snape spoke to him with contempt, and punished him at every opportunity. It was well known that neither liked the other, but since Snape hardly ever got on with students outside his house, and Harry very much in Gryffindor, no one thought anything of it.

5 years of Hogwarts passed uneventfully; Harry was well loved by the students but often up to mischief with his friend Ron. Even so he still managed to be made a prefect in their 6th year, which is why, it was all the more surprising when he got in detention himself in the first few weeks of his 7th. It had been Malfoy's fault. He should have smelt the trap, but Malfoy had managed to get him caught with some not so legal items. It had been enough to strip him of his prefect badge and get him on detention with Snape for the whole term. Not only that, but the story of his fall from grace had spread around the school incredibly quickly, getting more and more embellished as it went. At every corner there were students whispering and giggling in his presence. His face would usually colour and he tried to ignore them, cursing Malfoy under his breath.

The day of his first detention, he trudged unhappily to Snape's classroom. Snape was sitting, waiting for him. He sat in silence, watching harry for a moment, before standing and grabbing a piece of parchment.

"I have devised a list of jobs for you to do as punishment. Unfortunately because of the volatile nature of some of the substances in this room, and your general untrustworthiness I cannot leave you to your own devices. But I do not relish having my evenings taken by you Potter, as much as a relish being the one to deliver your much over due punishment."

He handed Harry the list of tasks. Harry looked steadily at the parchment, not really reading it, but trying not to let his temper get the best of him. All he could think about was how unfair this all was.

"As you can see the first on the list is cleaning one of the potions cabinet, this must be done with great care. I cannot stress this enough. All the potions must be taken out of cabinet, placed on that table in the exact same order, once the shelves are clear you may clean them."

Harry nodded sullenly.

He began the task, aware of Snape watching him snidely from the corner. Obviously enjoying it. He was just clearing the last of the bottles when he tripped on slight step between the storeroom and the table. Snape Rushed in to save the potion, but the bottle. crashed on impact splashing them both in the red sickly liquid it contained.

Harry felt the potion seep into him it made his skin feel hot and tingly. He turned to look at Snape, blinking as a red tinging clouded his eyesight. For some reason his breath had become laboured and he could see it was having the same affect on Snape.

"Stupid …Stupid… boy!" Snape growled at him. "Did I not .. . speci..fically..say… be..careful…"

Harry was starting to feel very strange, "What was.. it?" He asked Snape who was already examining the bottle. He cursed in alarm and looked at back at Harry.

"Stay where you are. Don't come near me."

"Why… What is it? What… does… it do?" The urgency in Snape's voice was making Harry very much afraid.

"This potion … will take full ….affect very soon…, It will …hurt but …you must you must…stay where you are."

Harry thought bitterly how Snape was being so cryptic in order to mess with him. But some how he couldn't hold onto the anger, instead all he could focus on was the sensual way Snape's chest heaved. He couldn't stop focusing on Snape's mouth. He felt a great urge to touch it, to kiss it. He shook his head, alarmed by these thoughts, trying to dislodge them. His eyes met Snape's. They were filled with the same longing. He realised the shortness of breath came from burning desire. It almost hurt how much he wanted to be touched. He felt himself moving. Some part of him still sane cried to make him stop. But he couldn't. Snape watched his approach, his expression a mix of pleading distress and equal lust. As they touched, a surge went through Harry's body. Snape could restrain himself no more, He pulled Harry in for a kiss. It was strong and rough and Harry had never experienced anything like it. It consumed him. All reason, all knowledge that Snape was his hated teacher. All thoughts outside the desire to touch and be touched by Snape vanished. The potion took full effect and both Snape and Harry were helpless under its power.

They both woke from the potion filled hazy sometime around 2am, limps still intertwined. Covered in sweat, still heavily breathing from the experience. Harry felt sore all over. He rolled over, unable to find anything to say. He grabbed his robes and struggled to put them on. Snape said nothing either. He groaned and curled in a ball, still naked. Harry left. That night, every time he closed his eyes he saw Snape. He saw small moments of what they had done and he didn't know what to do.

Snape cleaned up his classroom as best he could. The stench of sex still lingered. His hands trembled as he remembered how he had taken the boy. He was filled with self-loathing. He was still a boy, only just seventeen. While by wizard law he was of age. He was still a child, a student. Not just any student, he was Lily's son. He had defiled Lily's child. As much as he thought Harry an insufferable brat who was just like his father, Harry was still an innocent boy.

Part of him wanted to tell Dumbledore straight away. He must be fired, be punished for what he had done, but he couldn't do it. To own up to it would make it real. It would acknowledge the fact he wanted to do it, which he didn't. It was the influence of that damn potion. Still his face reddened as he remembered how it felt, and he couldn't help but feel aroused again.
