Summary: Harry and Draco aren't really sure what it is between them but they do know there's only a fine line between loathing and desire and a fist fight can easily turn into a kiss. They don't want to do it but they can't seem to keep away from each other and one of them always comes back for more.

Author's note: Hello all! This is my first HP/DM fic so please read and review. I'm not sure how long it's going to be because this just came from some random ideas that were bouncing around in my head but it should be about 4 chapters at least, I hope so anyway. I don't have a beta at the moment and I think I'm doing fine but tell me if you reckon I should get one. I was inspired to write this fic by the song 'Again & Again' by The Bird and the Bee, give it a listen if you feel like understanding where I'm coming from, those are the lyrics at the beginning too.

I hate you, I want you

You're so stupid and perfect
And stupid and perfect
I hate you, I want you
I hate you, I hate you

Harry grumbled disjointedly to himself as he scrubbed the stained and uneven floor of the potions classroom. His arm was aching from at least 3 hours hard cleaning. It must be nearly 11 o clock and Snape had still not come to send him to bed. He sighed and sank back on his haunches, rubbing his tired elbow. He was still wound up that Snape had given him a detention for just glancing away from the board during their lesson, apparently he had been 'daydreaming'. He heard footsteps echoing down the stone corridor towards him, he looked up hoping it was Snape coming to send him back to his dormitory, who thought I would ever be hoping to see Snape? He thought to himself. But the figure that emerged in the doorway wasn't the hook-nosed form of the potions master, it was Draco Malfoy. "Evening Potter" he drawled. "What do you want Malfoy?" Harry spat back, "Isn't it past your bedtime?" At this Malfoy snarled, twirling his wand in his fingers, "I'd hold your tongue if I were you Potter, Snape's still got your wand hasn't he?"

Harry grimaced, knowing Malfoy was right. He stood up and brushed the grit off his robes. "Come here to gloat then?" Malfoy smirked, "Well, partially, but really Potter, you alone and wandless in an empty classroom? How could I resist?"

"You wouldn't" retorted Harry, knowing full well that Malfoy most definitely would.

The two boys glared at each other for a split second before both launching into action. Malfoy cried "Flagrate!" and Harry leapt towards the other boy, narrowly missing the jet of fire that shot from Draco's wand. Harry tackled Draco to the ground and soon they were a mass of kicking and punching limbs, Draco's wand lying forgotten a few meters away. Draco soon had a split lip and a purple bruise was rapidly blossoming on Harry's cheek.

Although Draco was slighter he was taller than Harry and had successfully pinned him down. His right hand held Harry's wrists still at an awkward angle and his leg was over Harry's thighs, holding him to the floor. He smirked triumphantly down on Harry's squirming form, leaned in close to his ear and whispered

"I win."

This comment appeared to drive Harry over the edge, he would not lose to Malfoy. He never had before and he did not intend to start. He lashed out furiously, his fist striking Malfoy's jaw. The pale teen grimaced and spat a mouthful of blood out over Harry's shoulder. Both boys struggled for dominance as they rolled over and over on the stone floor. Arms and legs thrashed and scratched and kicked, by this time they were standing again fighting each other into a corner. This time Harry seemed to be winning, he pushed Draco against the wall and only then did he become aware of the way he was using his body to stop Draco's from moving, the way they were pressed so tightly together. Malfoy somehow managed to smirk whilst being held in Harry's death grip, their breathing was short and ragged, their cheeks flushed and their pupils dilated. "Potter, I do believe you're getting off on this" he sneered, in an attempt at disdain when in reality his heart was beating fast enough to burst through his ribcage and his quick shallow breaths made his voice sound oddly faint and far away.

"No more than you are" Harry spat back.

The two boys stared at each other, their chests heaving, each filled with an uncontrollable hate, or was it lust? Neither could really tell anymore, and before either of them had time to register what was happening or even who had initiated their lips had crashed together in a bruising kiss, their tongues tangling, teeth biting on lips. Harry tasted the coppery tang of Malfoy's blood in his mouth and felt the slick sheen of sweat on Malfoy's skin under his fingers. He gripped hard on the blond boy's shoulder, leaving marks that would stay until morning. Malfoy had twisted his hands into Harry's hair tugging hard enough to jerk his head back leaving him free to explore Harry's exposed neck. He bit down hard, leaving a wicked crescent shaped mark, and Harry let out a raspy groan which only spurred Draco on, his tongue flickering over the throbbing pulse point. As Draco snaked his hands up under Harry's shirt and ran his nails down the muscled torso, leaving angry red scratches, Harry let out a long low hiss, "Malfoy… oh god, do that again… no don't! Merlin, what are you doing? What are we doing?" he whimpered, although me made no move to loosen his grip on Draco's hip. Malfoy's reply was muffled in Harry's tousled hair; "Shut up Potter". Harry almost laughed but this quickly turned into a guttural moan as Draco's thigh pressed in between his own and he felt the other boy's hard length pressed against his leg.

Suddenly Harry felt a warm hand creeping past the waist band of his trousers and hovering somewhere in the region of his crotch, dangerously close to his growing erection, although he wanted Draco to touch him with every fiber of his body the touch made him feel sick. He quickly wrenched himself away from Draco's warm body, his head spinning, he took one look at Draco and tried to run, but Malfoy was one step ahead of him and he felt Draco's hand grab his wrist, his fingers circling the quick pulse.

"What the fuck is wrong with you Potter?" but Harry merely gaped, the nausea threatening to overwhelm him. Draco soon sensed that this was not just a momentary lapse and threw Harry's arm down as if it had burned him, looking disgusted. "Whatever Potter" he snarled, shoving Harry out of the way and striding out of the room without a backward glance.

Harry sank back down to the floor, panting, with his head in his hands. What just happened?
