Detention with an Omega

Draco thought Harry was an Alpha. What else was the saviour of the universe supposed to be? He doesn't realize how wrong he is until they share detention one evening. Omegaverse. Alpha Draco, Omega Harry. Smut

Harry Potter and the wizarding world surrounding him belong to J. and WB productions. This is purely a hobby and I don't make any profit from this.

How dare professor Slughorn give him detention for a whole week? He had just misplaced a drop of Amortentia in Zabini's water bottle so he would kiss Pansy once and for all. They had been flirting for months now that the war was over. They had their whole 8thyear to be children again. Anyways, a drop of Amortentia wouldn't hurt anybody. Even more, between people that already had feelings between them. And since they were both Betas they were made for each other.

Draco made his way from the Slytherin common room to the potions classroom. He had already had supper and was expecting about two hours of detention, leaving him no time to relax in front of the fire with a book before going to bed. He missed Snape. He would have never given him detention for such a petty thing. But he was gone, as were most of the people he cared about after the war, but it was ok. He was strong, he'd be fine, or that was what he tried to convince himself of.

Harry hadn't thought it mattered if the rose petals were one colour or another. What was the difference between red and dark magenta rose petals? Nothing. But clearly there was. His cauldron had started to bubble and produce some horrible fumes that irritated everybody's eyes and throats when they breathed it. They had had to evacuate the classroom and Slughorn had given him detention. This wouldn't have happened before the war, but of course Slughorn had noted Harry's unwillingness to boast of his prowess. After that, he had lost interest in him as one of his trophies and treated him the same as any other student. He didn't really mind detention, since it would give him an excuse to leave Hermione and Ron alone. As they had discovered their feelings for each other, they started to become more and more of a snuggly couple. Kissing each other for no reason in public, holding hands everywhere, whispering things in each other's ears… Harry loved them and was happy for them, but even he had had enough. Ginny and Harry had ended their relationship when she realized he was an Omega. She had supposed he was an Alpha, as did everyone, and he never bothered to correct them, but Ginny had minded, knowing she would never be sexually satisfied as she would by an Alpha. She was also Omega.

He hadn't expecting to share detention with anybody, but when he saw dark hair he stopped in his tracks. Harry Potter, the golden boy, saviour of the wizarding world, the boy who lived twice, was standing in front of professor Slughorns' desk, grabbing a piece of parchment that was given to him by the professor. As he regained his bearings he stepped through the door, clearing his throat so as to make his presence known.

- Oh Draco, just in time, Harry has the instructions as to what you have to do. I will retire to my chambers and evaluate your work tomorrow.

Professor Slughorn said. Draco didn't understand anything:

- Professor, with all due respect, you don't have to leave Potter watching over me. I'm sure he has better things to do and I can take care of the potions classroom by myself.

Professor Slughorn laughed at this.

- Oh, no hoho. Harry is also in detention. He will be helping you, not supervising.

Draco blanched. Potter in detention with him? Why wasn't he complaining at all? He was just standing there, looking at the exchange with a blank face. How he despised that. It was something that had become usual in Harry ever since the war ended. He didn't show many expressions, and his blank faces were impassive, without a crack in them.

- I am retiring now, please finish until the 4thtask today, you have the rest of the week to do the others, but these first ones are a bit of a pressing matter. Good night.

Professor Slughorn left the classroom, leaving the two boys alone. Draco faced Harry and stretched his hand out, silently asking for the piece of parchment. Harry handed it to him without missing a beat and turned around, heading to the ingredient cabinet. He read the first four items on the list:

1stOrganize the ingredient cabinet

2ndClean out the cauldrons

3rdTake the soot out of the fireplace

4thErase rude drawings on tables

Oh fun, another teacher using detention to lessen their workload. He went to follow Harry to the cabinets.

He didn't know he would have to do detention with Malfoy. He had testified for him in his trial so he could avoid Azkaban, but that didn't mean they were the best of friends. They weren't on each other's throats like previous years, but they hadn't talked since the last trial date, and that had been at least two months ago. He didn't know anything about him, how he was holding up, how he was coping now that his father was in Azkaban and his mother had been admitted in St. Mungo's mental health ward. He was as pale as ever, and avoided looking at him, but Harry had to admit, the Alpha had presence.

- I think you're more watching over me, than me over you. I'm still not very good at potions, and ingredients are my worst part.

He tried some light small talk. The tension killing him. The jars full of weird ingredients clinked as they starting moving them around.

- Don't worry Potter, you don't have to make small talk. I know both you and I are bad at it. I'm perfectly fine staying in silence.

Yep, Malfoy was treating him the same way he had during the trial. Cold and distant but respectable.

- I'm not trying to make small talk… Or maybe I am a bit. I'm not comfortable in silence, not since… Anyways, what got you in here?

- My feet Potter, you know we can't fly brooms in the castle.

Well that was a bit of snarky humour at least. He waited to see if he would say anything more.

- I put Amortentia in Zabini's water bottle to get him together with Pansy.

So that's what had happened. Pansy had been on Zabini's lap for supper in the great hall. Neither of them had touched their food, and had spent the time staring into each other's eyes.

- Didn't know you were Cupid under your human skin.

Harry said smiling.

- What did you call me, Potter?

Oh right, muggle mythology. Malfoy wouldn't know anything about that.

- It's a muggle god of love Malfoy. Don't worry about it.

Potter was smiling. Not only that he was smiling at him. Talking to him and even joking a bit. Why? He thought he had finished his pity party after his trial. Why would he try to have a civilized conversation with an ex-Death Eater?

- Me? A god of love Potter? Are you quite ok in the head?

The other boy chuckled, his blank face disappearing for a moment, a smile on his face. A real smile, the type that reached your eyes.

- Sorry, I didn't mean to offend, Draco. Can I call you that?

He turned a bit red before saying:

- Potter, you can stop it with the pity party. I know I'm a wreck, but I dislike pity more than anything in the world. More even, coming from old rivals.

Potter turned to him at that, facing him fully.

- I never do anything out of pity Malfoy. I myself have received enough in my lifetime to know why it is disgusting. I would never insult somebody who is suffering like that.

Draco turned to look at him. He had forgotten his parents were dead. How did he pass up something like that? Merlin, he had seemed like an idiot, only acknowledging his own pain.

- Hadn't thought about that… Sorry Potter.

Harry passed him a jar that went in his cabinet, and as their fingers touched he said.

- Call me Harry.

He had to admit defeat.

- Then call me Draco, Harry.

A few moments passed in comfortable silence. Both basking in the knowledge that they were getting closer. As Harry felt a warmth in his heart he also started to feel some pressure in the back of his head. It didn't hurt, but it was bothering him. He scratched the nape of his neck to try and alleviate it. It only made it worse, feeling his nails on his skin like claws.

- What got you in here? You asked me before, but you didn't say yourself.

Draco asked, still moving glass jars around the cabinet.

- Rose petals. I got red and dark magenta confused. Foul smell, had to evacuate the whole class.

Damn he was starting to lose strength in his arms. He had to hold on to the lowest cabinet shelf, setting the jars down while trying to compose himself.

- Good lord Harry, never took you as colour blind.

Harry tried to answer something snarky, but instead a guttural sound was all that came out of his mouth. Draco turned to look at him, confused.

- Merlin Harry, you look awful. What's wrong? Is being colour blind such a touchy subject?

He was trying to concentrate on what Draco was saying. Trying to remain here and not float off into the dark that was clouding his sight now.

- Harry? Oi, Harry?

A last clink of glass was all he heard before losing consciousness. The dark overtook him.

Draco managed to catch Harry just as the other boy started to fall backwards. He wasn't strong, but he was taller than Harry and managed to grab him and lay him on the floor without causing neither of them great damage. He sat down next to the sick boy, taking his pulse and feeling his forehead to see if he had a fever.

Not only did Harry have a fever, but he was sweating, his breath ragged, his eyes fluttering.

- How Gryffindor do you have to be to come to detention sick? Sometimes I wonder how you are still alive.

Draco was weighing his options. Go to Slughorn and tell him he couldn't finish the detention because Harry had fallen sick? Should he just take Harry directly to Madam Pomfrey? He certainty couldn't take him to Gryffindor tower, thy would kill him there. Just as a plan started to form in his mind something caught his nose.

It was sweet, but not sickly. It had to be delicious, but it also turned him on, his cock starting to harden. He hadn't smelled an Omega in heat in so long. They usually supressed them with potions nowadays. The last time he had smelled one, it was in the Manor's dungeons. His father had brought an Omega to teach him what it meant to be an Alpha. He shuddered at the memory and thought back to the present.

The only other person in the room with him was Harry, and he was an Alpha, wasn't he? Or at least that was what the whole school thought. So, he wasn't an Alpha… but why hadn't he taken his suppressant potion? Heats were regular and Omegas were encouraged to track them closely to be able to manage them. How had Harry let this slip?

He got up and went to the other end of the room, as far away as he could from the boy, but still in his view. He grabbed a cloth and sloshed some rosewater on it. He covered his nose and waited for the boy who lived to wake up.

The world cleared around him. The dark leaving his mind, letting him open his eyes. He could feel the cold floor on his back and his arms, he saw the ceiling of the dungeons and struggled to understand what had happened. He heard a sharp gasp and he turned his head towards the sound. He thought it would hurt, but on the contrary, the more he came out of the blackness the more alive he felt.

As he turned to look at the sound he saw Draco, sitting on the floor at the opposite corner of the classroom, his mouth and nose covered with a cloth, eyes watering, a weird bulge between his legs and red as a tomato.

- What's got you all flustered Draco? You look like a cherry.

Draco scrunched his eyebrows while looking apprehensively at him.

- What the fuck Potter? You're an Omega? Why the fuck didn't you take your potion?

What? Harry was confused. He was Potter again, Draco also knew he was an Omega, and what was he talking about potion?

- How do you know I'm an Omega? And why are you sitting so far away? Are you disgusted by me now that you know I'm not an Alpha?

He was angry, but he was also happy. His emotions were running high. He hadn't felt them this clearly after the war. Now that the dullness had left him, feeling every one of his emotions fully he couldn't identify half of the ones that were manifesting now.

- This is not the time to get political Harry. Tell me why didn't you take your heat suppressant potion.

Heat? That was impossible… He had been left broken after everything. How dare Malfoy ask him such a personal thing. He was fuming.

- Because I'm not able to be in heat. Ever since the war… my PTSD doesn't even let me get hard, much less go into heat. That's what the healers said, if you have to know.

Harry saw Draco get up from his spot, cast away the rag that had been covering his face, and started to stalk over to him. All at once Harry could feel it, the hot feeling of want through his veins as he smelled the scent of an Alpha. He knew colour was flooding too his cheeks and other parts of his body and tried to look away from Draco's silver and hungry eyes. God, how could a Slytherin turn him on so much?

- Are you still so sure?

Draco asked as he kneeled next to Harry. His bulge grew in the proximity to the Omega and Harry didn't miss it. He moved to sit up against the wall and face Draco head on.

- It's supposed to be impossible… I haven't had one in the last year. I had even forgotten my cycle. I… I don't know what to say.

He didn't know what to say from his shock. But he also was distracted by all the scenarios his brain was providing him. Draco ripping off his pants and fucking him to oblivion. Sucking Draco's dick and having his ace covered in his cum. Having Draco blindfolded while he fucked himself senseless on his dick…

- Draco I'm… let's… I want you.

His lips said before he could think about what he was saying. The heat was taking over, he could only think about his desires. He felt hot and fevered, his pants starting to get wet, and his breath coming out in short gasps.

- Don't regret this later… Ok Harry?

He could feel his own heat taking over. The Omega scent had triggered his own heat, and now that he was so close to Harry, inhaling him deeply and seeing his eyes bright with lust, he knew he was close to losing his control.

- Don't regret this later… Ok Harry?

He had been a pleased with their previous conversation, as short as it had been. He had thought they could have become acquaintances, friends even. He didn't want to lose that opportunity.

He looked at Harry one last time, trying to see into his soul, but only seeing the hot sheen of lust on them. He looked at his lips, he was biting on his lower lip sexily, before kissing him. He had wanted it to be a kind and gentle kiss. But as soon as they were in contact all hell broke loose. The kiss was hot and needy, rough. Their teeth clicked against each other's, tongues fighting for dominance.

Harry moved to sit on Draco's lap, without ever loosing contact. As the kiss deepened, and became an open mouth battle, their hands started to roam all over each other. Draco raked his nails over Harry's back to feel him shudder in pleasure with one hand. The other in the dark unruly hair, making the boy follow his lead. Harry had one hand on the others neck, his thumb caressing his jawline, while he grabbed at the robes on Draco's chest so as not to let the other leave his side. And as they continued kissing, inhaling each other's pheromones, they had the need for more. Draco moved his hands down to Harry's lower back, playing with the waistband of his trousers. He tugged at them, in his hazy state not understanding why they didn't pull down. He understood when Harry started unbuttoning his shirt, already having tossed the outer robes aside. Draco moved his hands between their two torsos. Struggling to undo the button to Harry's trousers because of his impatience. Harry had managed to take off his shirt and had starting undoing his own, button by button, never stopping the hot kiss between them. As he finished the last button on his shirt and tossed the thing aside, he went to his trousers and undid them himself, noting Draco's uselessness in the matter. Once they were undone though, Draco was fast as lightning. He pulled away from the kiss, pushing Harry to the ground and in one fell swoop taking his trousers off and sending them flying to a corner in the room. He left the other teen in his boxers, a beautiful sight. His lips red and ravaged. His hot, tan skin all on display against the cool floor of the classroom. His eyes half hooded in passion, his erection clear now, a few stains of precum already staining the underwear. Draco lunged and pressed his length against Harry's. Grinding against him, feeling a hot sensation pooling in his stomach. Harry moaned his name, unaware of how good it sounded to the Alpha.

- Draco, please… kiss me again. I need you.

Draco's mind went blank with need he grinded again and kissed Harry. Biting his lips, letting his tongue rove all over him. He then moved his hands, lowering the boy's boxers. He pressed his ring and middle fingers against his entrance, noticing the wetness that had already built up.

- You're so wet. Do you know that? God, you must be horny.

Draco sighed as he entered Harry.

- Aaaah, yes! Yes!

Harry reacted immediately to Draco's fingers. He noticed how tight Harry was around him, how warm, how wet. It turned him on so much. He moved his fingers trying to find the prostate.

Harry knew exactly when Draco had found what he was looking for. He gasped as the blonde pressed his fingers against it.

- Draco what?...

He was too turned on to understand what was happening. What he did understand though, was that the more Draco pressed there, the more he could feel his orgasm pooling at his stomach. His legs started doing little spasms. Draco's breath in his ear reminding him of the hot kisses that they had shared.

- Harry, come for me.

The words tipped him over the edge. Hot cum spurting out his hard cock. Rolling out tides of pleasure. Draco didn't stop fingering either. It was nearly too much pleasure, but Harry revelled on the fine line between enough and too much. When the last of his orgasm left him, hooded eyes looking up to the pale face he had come to find so attractive, he saw fire in his eyes. Pure and steaming hot lust.

- Do you know how sexy you look with all that mess on you?

Harry smiled. The haze of pleasure making everything fun and beautiful.

- Merlin, that was nice... Thanks Draco.

But he was wrong. Draco smiled playfully, his eyes roaming over his soiled body.

- We haven't finished yet, my sweet.

He took his fingers out of Harry, and swiftly took his own trousers off, his own boxers on display now. He pulled down the front to let his dick out. Big and hard, and as pale as Draco had ever been. Harry felt his cheeks redden at what was coming. He saw Draco grabbing his legs and putting them over his shoulders.

- Can I?

He asked, eyes pleading, as he positioned himself, a little pout on his lips. And as soon as Harry nodded he felt his dick. He felt the whole thing, first the tip, then the long and thick shaft, until there was the faint slap of skin on skin. He loved the sensation, being loved all the way, he hadn't ever felt it before. He didn't know if he would be able to live without it after this.

Harry was so tight around him, so hot, so wet, so his. He had to remember himself for a moment to avoid cumming all at once. And when he felt ready he started to move. First it was slow. And oh, how good it felt. He felt the cool air against his wet cock as he came out of Harry, and when the tip was nearly out he would slam back in. Harry, underneath, writhing in pleasure, moved his hips to try to find a rhythm between them. Draco started up a faster pace until they were both humping at the same time, moaning and sighing, enjoying the sensation. Then Draco felt it, it started hot in his dick, and moved to his abdomen. There it grew bigger and bigger.

- I'm… ugh, I'm cumming Harry.

He pulled out just in time, cumming all over Harry's already soiled chest. Grunting with the pleasure that came and came, he noticed the other teen cumming at the same time. Both their cums mixing on his stomach, the same way their pleasures had.

As the last waves of pleasure subsided, Draco laid beside him. He entwined his fingers with his, and waited for his breath to come back. He hadn't ever felt anything remotely the same.

- So… I also have detention tomorrow.

He said when he was sure his voice wouldn't fail on him.

- Oh, well it seems I also do… Do you maybe want to…?

- Yes, a million times yes.

Fin.
