Summary: Harry has summer lessons with Snape. Before NEWTS, something happened. When the situation repeats, will they embrace it, or let it fall through the cracks? HPSS. Slash. Graphic M/M sex scenes.

~*~

Severus couldn't believe his luck. Three weeks ago, right before NEWTS were due to begin, Potter had the audacity to approach him for something other than help studying. The boy practically flirted with him.

"God, he looks incredible though," Severus muttered, giving into his inner most thoughts. "His hair always looks as if he's been thoroughly shagged. He's built like a seeker should be. His glasses give him the intelligent beyond his years look."

The Potions Master shook his head, attempting to clear the inappropriate thoughts. He was having them far too often. NEWTS had passed, and the students still had about a week before they were due to depart.

Unfortunately for Severus, Harry and a number of students in his year would be staying behind to train for the impending war. Even more unfortunately for him, Harry would receive private tutelage from Severus himself.

"What have I gotten myself into?"

~*~

Harry sat in his room, wondering how the first private lesson with Snape was going to go.

"I just had to fucking do that three weeks ago, didn't I?" Harry said, lying back on his queen-sized bed. "I had to go and make things between us worse…"

Harry had known about his growing feelings towards Snape since fifth year. However, he had never actually acted on them, even in the forced Occulmency lessons. He knew about the secret art of Occulmency, and he had already began actively practicing it, especially around Dumbledore and Snape.

"I made such a mess for myself," Harry grumbled, before turning onto his side. He stared out the window, wondering what Snape was doing.

~*~

The Room of Requirement was prepared for him when Severus arrived. There was a large dueling platform in the center of the room, and strong shields protected the walls, should any potentially dangerous curses be sent wild.

His thoughts had strayed to the lithe, young body that had invaded his thoughts over the last month far too many times for his liking. It was bad enough he had seen the boy in his classroom for seven years. Now his dreams were filled with increasingly more sexual happenings each night.

"It's not right," Severus said, walking around the room. "It's just not right. It's like that stupid 80's rock song."

Unfortunately, that was exactly what it was like for Severus. Alice Cooper's song "Poison" fit him too well, especially the chorus line.

I want to love you, but I better not touch (Don't touch)
I want to hold you but my senses tell me to stop
I want to kiss you but I want it too much (Too much)
I want to taste you but your lips are venomous poison
You're poison runnin' through my veins

It was almost too much for the 38-year-old man to handle. In his years, Severus had lusted after older and younger men alike, but they were never more than a few years either way. Harry was literally less than half his age. Half!

"This is inane," Severus spat. "The boy should not be encompassing my thoughts after one little kiss."

~*~

Harry had woken at 5:45, a full three and a quarter hours before he was supposed to meet Snape in the Room of Requirements.

"That was a pretty intense detention," he grumbled, lying on his back, staring at the canopy on his bed.

He allowed the thoughts to wander in his brain, replaying the night in question….

FLASHBACK: THREE WEEKS PRIOR

Harry had entered Snape's office on time for what he hoped to be his final detention.

"You'll be scrubbing cauldrons, Potter," Snape spat, gesturing to the right-hand side of the room, where at least a terms worth of disgusting cauldrons sat. "Needless to say, you will do so without magic."

"Yes, sir," Harry said, before divesting himself of his robes. He rolled the sleeves of his school shirt to his elbows and got to work.

After nearly four hours of scrubbing, scraping, and polishing, the cauldrons were in all their cauldrony glory. Harry's left arm felt as though it was going to fall off as he stood to face Snape.

The professor hadn't noticed that Harry had finished. He was off in his own little world, his eyes trained on where Harry's ass had been moments ago.

"Professor?" Harry asked, stepping over to Snape. No response.

"Sir?" Harry asked, stepping closer. Still, no response.

Harry felt daring, and there was little he could do to stop himself. He pressed his lips to the thin ones on his professor's face. Surprisingly, they were warm and fit nicely with Harry's. They responded instantly, opening to allow Harry's tongue into the professor's mouth. Their tongues danced for a short while, before Snape snapped to his senses. He shoved Harry away from him.

"What the hell do you think you were doing?" he barked, appalled that he had allowed that to happen.

"Um," Harry mumbled. "Kissing you, sir."

"Why the bloody hell did you even consider that?" Snape hissed.

"I've liked you since fifth year, sir," Harry said, his eyes searching Snape's face.

"You've liked me since fifth year? That makes kissing your teacher appropriate in what way?" Snape said, standing to accentuate his full 6'3" height.

"I don't know, sir," Harry said, his 5'8" stature being towered over. "I shouldn't have done it."

"Bloody right you are," Snape snapped. "Now get the hell out of my sight."

Harry was more than happy to put as much space between himself and the seething Potions professor.

~*~

Severus looked up as he heard the door open. Harry entered, a full half hour early.

"Good morning, Professor," Harry said, keeping his eyes averted. He had wondered what was going to happen after the incident.

"Potter," Severus answered. "Today, we will begin with simple spells that pack a lot of punch."

Harry paid rapt attention to the professor, memorizing each spell and the wand movement attributed to it. He needed to, if he were to have a chance against Voldemort.

After a few hours of learning the spells, what they did, and the wand movements, it was time to put them to use in a duel.

Severus was impressed by how the young man had paid attention, repeating things under his breath and continually repeating wand motions.

"Now, we duel," he said, getting into the proper position. He couldn't help but let his eyes wander as Harry did the same. The brat had definitely matured over the years, somewhat against his will.

They duel was a grueling forty minutes, but it was shocking to Severus. Harry had used wandless magic on a few occasions that he had been disarmed. There was no mention of Harry being wandless.

"I must say, Potter, that your skills are impressive at this stage," Severus said, slumping onto a couch that had just appeared along the far wall.

"Thank you, sir," Harry said, collapsing on the floor, breathing heavily.

~*~

Harry could not believe that Snape had just complimented him, and even more shocking was that it wasn't offhanded.

"What do you say to going to the Great Hall and grabbing something to eat? It's well after lunch, and nearly dinner, but we've been up here all day," Snape said, getting up and offering a hand to Harry.

"Sounds great," Harry said, taking the offered hand to get up.

Unfortunately, Harry used a little too much force, and Snape found himself with a lapful of Harry.

"Bloody fuck," Snape thought, his eyes finding Harry's. There was something in those emerald pools that he couldn't place.

"Sorry," Harry said, getting to his feet. "I didn't think I'd wind up knocking us both over."

"It's alright, Potter," Snape said, getting up and dusting off his robes. "After we grab a bite, we'll go into my office to study a few potions."

"Yes, sir," Harry said, his eyes alight again.

~*~

Severus was nervous about being alone in his office with Harry again. He could have cut the sexual tension in the room with a well-placed cutting hex. There was no way they'd both be able to stave off the urges much longer.

After they ate a hurried meal, they went into the office.

"Do we really have to do potions tonight?" Harry asked, stretching and yawning. "After the rigorous morning regimen today, can we just take it easy?"

"If you do not wish to study potions tonight, you may leave," Severus said, internally happy that he would not have to stave off the temptation much longer.

"I don't want to leave, I just don't want to study potions," Harry said, his eyes on Severus.

Severus stilled, his breathing becoming quicker. He was in over his head, and there was no way he could talk his way out of it.

~*~

Harry could sense that Snape hadn't forgotten about their last encounter in the office. He smirked a bit, seeing the reaction it brought out of the normally stoic Potions Master.

"You still think about it, don't you?" Harry asked, sitting on the chair behind the desk. "What happened the last time we were alone down here."

"Unfortunately, yes, I do," Snape spat. "What's it to you?"

"You want more of it," Harry said, standing. "You know you want more."

"I don't want more of anything," Snape said, backing away from the young man. He soon found his back against the wall.

"You want more of this," Harry said, stepping over to Snape, effectively pinning him to the wall. Harry's eyes were burning with lust as he pressed his lips to Snape's.

~*~

Severus froze. Harry was kissing him. Again! He hadn't responded, though certain areas were. He could feel Harry's soft, warm lips against his own. His resolve was crumbling. Before he knew it, his had wrapped his arms around Harry's waist, and they were kissing passionately.

He felt Harry's tongue enter his mouth, and before he could stop it, a moan escaped him. Harry's tongue explored, taking in every sound and taste.

After a few moments, Harry pulled back, his eyes hooded.

"That wasn't so bad, was it?" he asked, smirking.

"No, it wasn't," Severus answered, his arms still around the lithe body before him. He was embarrassed that he had hardened as fast as he did, until he felt a similar hardness against his thigh.

"What do you say we go to your room?" Harry asked, hoping beyond everything that he got the answer he wanted.

"Follow me, Harry," Severus said, releasing the young man and taking his hand.

~*~

A/N: So, this is my new side project. Crash Love wasn't lighting my fire.

I guess the plot bunny nestled in my brain while I was playing RockBand with some friends, and one of them picked "Poison". The chorus line seemed like something that would fit a Sev/Harry relationship, especially from Sev' POV.

TBW should be updated soon, the next day or two, hopefully.

R&R, pls.
