Chapter 5 : Unusual detention.

Harry resolutely knocked on the door. Several minutes passed before any response came. Then he heard Snape's voice.

"Come in"

Carefully, Harry opened the door and slowly entered the dark room. Snape was at his desk, apparently grading papers. Harry waited in silence, but Snape did not give any indication he had even noticed the young man enter. Squaring his shoulders, Harry eventually cleared his throat to gain his professor's attention.

"Err... Sir? I've come to report for my detention..."

"I know, you idiot boy! I am the one who gave you this detention."

So pleasant, as usual. Harry thought. Well, at least he isn't looking at me like a psychopath as he did last time.

Time stretched and Snape still had not said a word. Harry started to fidget, feeling highly uncomfortable and not knowing what to do.

"Herm... Sir?"

"What is it this time, Potter?" Snape angrily raised his head from the essays he was grading to look at him. Immediately, his eyes became glossy and intent...too intent. Exactly like the time after Harry ran into him near the Gryffindor tower.

"You didn't say what I am supposed to do... for the detention I mean" Harry added when Snape did not seem to catch on, still feeling highly nervous from Snape's stare on him.

Snape seemed a bit put off, but recovered quickly. He sneered at him, but it was not as potent as his usual sneer. It seemed to lack... purpose. Just as if Snape did not really want to sneer at him.

"I thought it was obvious, even for you. Undoubtedly, you are even more dense than what I originally thought." He stretched a long white finger to a large cauldron which laid five feet away from his desk on the left side of the room . "You are to clean this... manually of course."

Harry moved to the cauldron and saw that cleaning material had been put beside it for him to use. At first he internally rejoiced at the fact that there only was one cauldron to clean, but when he inspected it, he realized that this particular cauldron was worth ten. First, it was huge. It reached Harry's middle, so its height was of about three feet and nine inches while it was three feet in diameter. Furthermore, it was covered inside and outside with dried blue stuff –what it was, Harry did not know and certainly did not want to know. And the whole thing appeared to be incredibly sticky. Harry pulled a face, but set up to the task anyway.

The sooner it is finished, the sooner I can get away from Snape. God, he really creeps me out. Harry thought.

.

As for Snape, he had never felt such agony. When the boy had knocked on the door, his heart had jumped in his throat, his mouth had gone dry and his cock had twitched. Trying to appear calm and collected, he had thrown some papers on his desk to pretend he was grading essays before asking the living wet dream to come in. Dear Merlin! Seeing him, smelling him! Staying calm and collected was an infinitely more difficult thing to do in front of Harry than in front of Albus. When the boy had spoken, his sex had become full hard and it had taken all his self-control not to jump him right then. He had done his best not to look at him, but concentrating was nearly impossible with this piece of ass wiggling just at the edge of his vision. After some effort, he had managed to make the boy do his detention. He had then thought he was saved. With Harry working on his detention, he wouldn't have to look at him, right? So he wouldn't be tempted to fuck him hard and fast, right?

But when Harry started to clean the cauldron, Snape realized giving this task to Harry was not such a good idea. Forget that, it was a really bad idea. For to do the cleaning, Harry had diverted himself of his school robes, which left him in a pair of tight muggle jeans and a too large t-shirt showing a pure white shoulder. Then, as if this sight alone was not enough to make Snape go mad with lust, Harry went on his knees to scrub the outer part of the cauldron. This sinful position immediately provided Snape's mind with visions of Harry on his knees in front of him, sucking his cock. Snape almost let out a loud moan, but managed to stifle it at the last minute.

Unfortunately, the torture had just begun. After getting on his knees, Harry began doing up-and-down movements so as to scrub the entire length of the cauldron, which caused him to display quite effectively his sexy tight little bottom to Snape's hungry stare. This time, he was not able to stifle a groan.

Harry stopped at once to look at Snape with a questioning expression on his face. Severus tried not to blush and racked his brain for a witty comment.

"Is it really necessary for you to do such large movements? Stop making a show, you are disturbing me. Besides, it is not that difficult a task" he said with his best sneer on his face.

This seemed to anger Harry nicely.

"Well professor, in case you didn't notice, it's enormously big, so I need to do big movements. And let me say it isn't an easy task at all. In fact it's very hard."

All the blood that was left in Snape's body came rushing to his already achingly hard cock. God, did the boy actually realize what he had just said? Hearing 'big' and 'hard' coming from that delicious mouth had seemed so obscene and so sinfully good...

Seeing that Snape was not going to respond, and he was in no shape to do so, Harry just shrugged and returned to his work, happy to have won the argument and to have avoided losing points or getting more detentions.

.

After about an hour, Harry finally finished cleaning the outer part of the cauldron. Getting up, Harry stretched his sore body and tiredly swept his sweaty brow. He would have liked to rest for a bit, but Snape had not taken his eyes off him since he had begun. With Snape staring so intently at him, he did not want to show any sign of weakness... the bastard would enjoy it too much. So he decided to clean the inside of the cauldron. That was not going to be easy. First, it was way dirtier than the exterior of the cauldron. And second, the cauldron was so huge that small Harry could not reach the bottom with his feet on the floor. Trying an idea, Harry bent over the edge so that the upper part of his body was inside the cauldron while the lower part was dangling outside. Finding the position highly uncomfortable as the edge was digging into his waist through his t-shirt, Harry nevertheless started to scrub again.

He had no idea what he was doing to Snape. Severus thought that this was the worst torture he had ever been subjected to; Voldemort's little fun sessions seemed like kids' play compared to this. The sight of the boy's ass dangling in the air at the perfect height to be taken by his rock-hard cock was almost too much. He wanted the brat so much and at the same time he knew it was wrong. It was the bloody potion that was making him want this-this... this abomination. A teacher desiring his pupil... that was wrong but for the life of him, he could not remember why.

Totally oblivious, Harry soon stopped his stupid idea. Blood was pooling in his head and he did not have enough balance to continue scrubbing in this position. Standing up, he rubbed his brow while breathing hard from the physical strain.

"Damn, so hot..." he muttered to himself, his activities having warmed him quite a lot.

Snape startled violently, dropped his quill and became very white. Harry looked at him, surprise by the sudden actions of his teacher.

"Something's the matter, profess..."

He did not have time to finish his sentence as Snape quickly stood up and nearly ran to the storeroom that was at the back of the classroom. Left alone, Harry pondered on what had just happened. He concluded that Snape might have had a fit of some kind or a bout of sickness. Slightly worried, he spoke up tentatively.

"Sir? Are you alright?"

No answer. Getting closer to the door, Harry tried again.

"Professor? Can I come?"

He heard a large intake of breath and Snape finally answered, in a panicked, urgent sort of tone.

"No, no! That is unnecessary. Go on with your detention. I'll be back shortly."

Harry was not convinced. Something was definitively wrong with Snape. He had that strange feeling in the pit of his stomach again and for some reason he could not pinpoint, he had the disturbing impression that it was somehow his fault. After all, Snape only seemed to have a problem with him. First in the Great hall at dinner, then near the Gryffindor tower and finally at this detention. It was always with him nearby that Snape did strange things or reacted in an unusual way. The indistinct guiltiness he felt made him worry about Snape and in a way care for him. Did Snape started to hate him even more or was it something else? Something he might have done these past few days...

Turning back to the cauldron, he decided to continue cleaning it while thinking about Snape, to gain time. He put it sideway on the floor so that he could crawl inside it on all four and do a more effective cleaning.

.

In the meanwhile, Snape was still in the storeroom, violently jerking off. With his pants around his ankles, he was holding on a shelf while his other hand was desperately pumping his manhood. Hearing the boy saying 'hot' just after his little show had been to much for him. When he had fled to the storeroom, his goal had originally been to avoid Harry in order to regain control of his body and to hide his state of arousal. But when Harry had said 'can I come', he had lost the little self-control he had left. So this led to him masturbating with dirty thoughts of a student who happened to be right in the next room.

With a shuddering breath, he finally came in his hand. He slid to the ground, boneless, enjoying one of the best orgasm he ever had (and he strongly suspected that the object of his fantasies' presence next door was the reason). Cleaning himself with a charm, he readjusted his clothes, schooled his features into a menacing scowl and reentered the classroom, a scathing remark on his lips for good measure.

But all thoughts fled his mind the minute he put his eyes on Harry. Or to be more precise, on Harry's bottom. The boy was half in the cauldron, his back to Snape, and he was scrubbing. To do so, he made a backward and forward motion on his hands and knees, moving in and out of the cauldron. These movements reminded with a striking accuracy of a lover's motion under the body of his mate, each move backward meeting the thrusts forward. Snape became instantly and desperately hard, despite having masturbated only seconds before. Only this time there was no stopping him. An entire week of building frustrations had taken its toll and Snape could not resist anymore after seeing this.

.

Harry was still scrubbing in earnest when he heard a gasp behind him. He stopped cleaning and cautiously stepped out of the cauldron to turn around.

"Professor Snape! Do you feel better?" he asked, letting concern show through his voice.

Snape did not say a word and he slowly advanced on him. Harry instinctively took a step back, bumping in the cauldron. This glint in Snape's eyes... That was exactly the same expression he had on Tuesday evening, after they had run into each other...

"Sir? Is there a probl-umphh!!!"

Harry was cut short by a hot pair of lips on his own. He was so shocked that he was unable to react. That was Snape kissing him. It was his evil potion teacher that was currently sticking his tongue in his mouth. It was an ex-deatheater's hands that were roaming his body, tugging at his clothes. Harry woke up from his shock induced state only when he felt his professor's erection pressing against his stomach. Braking the kiss, Harry began to struggle against Snape's embrace.

"Professor! No! Stop!"

But the older wizard seemed to be in a kind of trance and did not let go of Harry. On the contrary, he ravished Harry's mouth again with an intensity that made Harry forget how to breath and he pulled him even closer to his body. Harry then realized with horror that his own body was reacting to his professor's attentions. His once limp penis was getting bigger and harder with each new caress from his teacher and he felt as if his strength was leaving him.

By the time Snape pulled back from the kiss, Harry was panting and rocking his erection against Snape's thigh desperately, like a dog in heat. Snape then moved them both and pushed him against the nearest wall. Harry whimpered, the wall solid and cool behind his back and Snape hard and hot against his front. Harry gasped as Snape pulled back enough to get a hand between them. That graceful hand sought out Harry's jeans buttons and made a short work of them. Harry moaned and tried to protest as Snape's hand slid inside his underwear and wrapped around his dripping cock.

"Stop... please..." he panted desperately, trying to push Snape off him, but not having the strength (the will?) necessary to do so.

Snape's hand went even more rapidly on his member, stroking it quickly, savagely. And Snape said :

"Let go, love, just feel..."

"Oh god..." Harry cried out as his hips jerked, pushing his arousal in and out of Snape's hand, mind totally gone from all this pleasure. He was going to come, Snape was making him come and oh god this couldn't be real... Snape's hand tightened on his cock and Harry climaxed, helplessly, loudly, messily. The pleasure went on forever. Snape kept stroking him and Harry could feel the wet heat of his seed gush out. He came down slowly as Snape slowed his strokes and Harry caught his breath.

Snape cleaned Harry up with a spell, leaned down and kissed him more gently. Harry let him as he was unable to resist, his body still singing with pleasure and his breath short.

He froze as he felt Snape's hands slide down his back. When those hands got to his ass, he whimpered and tried to escape.

Snape picked up Harry, carried him across the room and set him on top of his desk. Harry's attempts to escape were in vain. Snape was much taller and stronger than him, but that did not prevent Harry from trying to flee nevertheless. During the struggle, with Snape trying to pin Harry down and Harry trying to push Snape off, Harry's legs opened and Snape slid between them...

Snape shifted and suddenly he was fully on top of Harry who gasped. The solid weight of the bigger man on him was intoxicating. He felt himself hardening again in spite of himself, the pressure almost painful but delicious. He could feel Snape's arousal, big and hard, and the implication of what the powerful man wanted to do to him brought him fear and excitement at the same time.

Snape kissed him savagely, pressing their bodies together, rocking his hips against Harry's returning arousal. Then Snape set to undressing Harry, frantically freeing him of his robes, t-shirt, jeans, undergarments and shoes. On each new bit of skin exposed to the cold dungeon air, Snape lavished kisses and strokes. Harry was turning his head from side to side, telling himself it was just a very twisted dream, in which he was being raped by Snape and enjoying it.

The potion master then used his wand to divert himself of his own clothes and summoned a jar of lubricant. After that, he stepped between Harry's legs more completely, pushing his knees apart further. Harry drew a shuddering breath as he was exposed to Snape's stare, and he tried to cover himself with his hands. But Snape stopped him.

"Don't... Don't hide. You are beautiful." He whispered. The look on his face, a painful mix of lust and... love, was something that Harry would not forget soon.

Snape's hands traced lightly down the boy's inner thighs. Harry gasped and tried to draw back. Just the man's eyes and hands on him made him feel like he was on fire, possessed. This feeling was very new to him, and he did not know if he enjoyed it or hated it.

Snape poured some oil into his hand, then ran that hand delicately up and down Harry's cleft, just ghosting over his opening.

"Merlin..." Harry said in a strangled voice. He then moaned deeply as one finger pushed against his entrance. Snape moved the finger in and out slowly and leant down over Harry, running his other hand down his chest. Harry whimpered in pain, but did not struggle anymore. That finger inside him felt odd, but at the same time it made him ache for more. He twisted, trying to escape the strange sensation, and Snape added another finger. The fingers moved inside him, and suddenly it felt so good he was nearly screaming, arching up off the desk.

Snape added yet another finger and Harry was panting now. He looked up at the dark-haired man. He still could barely believe this was Snape making him feel so much pleasure, that this was Snape caressing him and preparing him so tenderly, so lovingly. Then Snape withdrew his fingers and pulled out a very hard, very large cock from his boxer. He grasped Harry's hips, pulling him to the edge of the desk before leaning forward and pressing something very hot and thick against his love's entrance.

Harry let out a cry as Snape was pushing inside him, stretching him opened, filling him. It hurt. But it also felt so good and right. As for Snape, he was looking at Harry through half-lidded eyes filled with need and so much love... His breathy moans and his invading cock were driving Harry mad with fear, confusion, tenderness and desire.

Soon Snape was driving in and out of the pliant body, gripping his hips and building up speed. Harry was lost in a sea of sensations. Everything was too much. He could not think anymore, could not remember if he was supposed to push Snape off or to bring him closer, could not recall why he had not wanted it before and why he was letting Snape do this...

Snape continued to thrust deep in Harry and ran a hand down his chest.

"So perfect..." he breathed, "I want to stay in you forever. I want you by my side for the rest of our lives. I want to fall asleep with you every night and wake up with you in my arms every morning. I want to hold you and never let go..."

Harry arched up, loving the sound of what Snape was saying as he took him. He felt so loved, so safe...Something he had never really experienced before.

"Mmm, Harry... My Harry..." Snape whimpered, slapping his hips against Harry's bottom as he drove in deeper, faster. He wrapped his hands around Harry's cock to stroke it, and that did it for Harry. He came so hard he thought he would die from it. On and on he pulsed his seed over his chest and stomach.

Snape still drove in and out of Harry at a hard pace. When Harry was able to opened his eyes, he saw the older man watching him intently, obviously holding back his own release. Their eyes met and Snape sped up, murmuring 'Harry' just once before he stiffened and Harry felt himself being filled with his hot seed. His eyes were fixed on Snape's face, still not quite believing what had just happened.

Then Snape slumped down on top of Harry, breathing hard, and kissed him long and slow before pulling out. Harry just lay back, clutching at Snape's shoulders as if for dear life. Finally, Snape backed away a little to look at him and Harry had never seen such uncertainty in anybody's eyes. "Harry, I'm so sorry...Did I hurt you?"

But Harry was totally unable to respond or to give any sort of reaction. This had been his first time, and he never would have dreamt it to be so pleasurable, so perfect... But it was Snape who did it, who took his virginity and made him feel protected, loved and so complete... It was very disturbing. Not only because he now saw Snape as a sexual being, but also because he now cared for someone he was supposed to hate, and he wanted to stay in his arms a little longer after something that should technically be called a rape. It was so complicated and confusing that Harry's brain blacked out. He viciously pulled himself out of Snape's embrace, quickly gathered his clothes, put on his school robes over his naked body and fled the room, leaving Snape alone and miserable with his guilt and remorse.

To be continued.

Aww... poor Snape... Don't worry, I swear there will be a happy end.

A great thanks for all the sweet reviews. They are a real motivation.

.

For Strigoi : Your review was so flattering that I blushed in front of my computer. I honestly think you exaggerate, but that shows that you really like my fic, so it makes me very happy. Next chapter will be coming soon. Mmm... more Snape torture... Me? Evil? Just a bit .

For Wolverine'sGirl007 : Thanks for your enthusiasm, it was really refreshing. Don't worry, I've overcome most of my problems, so I will be able to update more regularly. Thank you again for your support.

For Christine : Don't cry, I won't drop this story. But I find myself at a crossroad. I've got a plot line that will finish the story in one or two chapters, and another one that will make the story longer. I still hesitate between the two (but knowing myself, I'm sure I'll make a mix of the two )

For Elehyn : Je suis désolée de ne pas avoir été plus précise. Si Fred et George sont encore là, c'est parce que cette fic se situe pendant la cinquième année de Harry. Donc Sirius n'est pas mort, le D.A fait ses débuts, Harry n'a pas encore eu de cours d'occlumency (vu que l'histoire se passe avant noël) et donc les jumeaux sont toujours là. Voilà. Sinon, merci beaucoup pour ta review, elle m'a fait très plaisir comme toujours. J'espère que ce chapitre t'a plu. Dans le prochain, je vais encore faire souffrir Snape, mais Harry y aura droit aussi. Tu vas voir ;-)
