More Teasing

All was quiet in the dark and gloomy Potions classroom, save for the gentle bubbling of the cauldrons and the smallest rustle of movement created by the NEWTs level students. They were brewing a tricky potion, one that required a lot of care and attention. One lapse in concentration and it could bubble over, or worse.

Harry stifled a yawn as he stirred the contents of his cauldron six times counter clockwise or was that meant to be seven?

He'd had another late night, not getting back to his dorm until dawn was threatening the horizon. He'd never realised how exhausting leading a double life could be, and held a new found respect and appreciation of how hard it must be for Professor Snape to spy for the light while continuing to teach Potions and fool Voldemort.

"Potter! Concentrate on your potion, unless you are trying to blow my classroom up?" Snape barked at him, causing Harry to jump about a foot in the air. He hadn't noticed the man had stopped by his workbench, which was highly unusual. Despite always doing his best not to look at Severus during class, Harry was almost always aware of where his lover was in the room, using his other senses to track him as he moved, getting a soft tingling sensation across his skin whenever that dark gaze swept over him.

"No," he mumbled, looking down at the table. Severus had caught him by surprise, but his reaction hadn't given anything away. And now it was time to play their parts to make the world believe they still hated each other.

"No, you don't want to blow my classroom up, or no, you won't concentrate?"

Harry slipped expertly into his sulky teenager façade. He'd been really surprised by how well he coped with the deception, with how easy he found it to act up in front of others so that no one would suspect their affair, not even Harry's friends.

"No, I don't want to blow the classroom up," he replied, glaring defiantly at his Professor. Internally he was smiling, he liked it when he could look at his lover during lessons without anyone getting suspicious.

Now came the bit where they would silently stare each other down before Severus faked an insult and moved on.

Harry looked up into those endless black eyes that he loved so much, and felt another yawn coming. He tried to stifle it, but he was so tired from the night before that it was no use.

Everyone was now watching to see what Snape would do to someone yawning in his face, but he just smirked down at Harry.

"Boring you, am I, Potter?" He said in a silky smooth voice that caressed Harry's senses and made it hard to concentrate. "We'll have to drill it into your thick skull just how important Potions is. Detention, tonight at eight."

"Yes, Sevvy."

A deathly silence fell over the classroom and Harry's eyes widened in shock and horror. He hadn't meant to say it, it'd just slipped out! He never called Severus anything other that Professor, Snape or git outside of the man's quarters. And it was very rare that he called his lover Sevvy inside his quarters, only when he was feeling particularly impish and Severus always got his own back.

Severus didn't say anything for a long moment. He just gave Harry a murderous glare that was a lot truer that usual, and the potion in Ron's cauldron chose that moment to bubble over and start eating its way through his desk, confirming to almost every student in the room that Harry had made Snape angry enough to cause damage without raising his wand or even looking.

Harry opened his mouth to apologise but Severus beat him to it.

"Think you're funny, do you, Potter? Well, let's see how funny you find a month of detentions then."

No one said anything, Harry didn't dare reply, he just bowed his head and moved his textbook away from the smoking puddle of potion that Ron had only just noticed was spreading gradually across and through their desk.

Severus swept back to his desk, where he remained for the rest of the lesson, glaring at anyone who dared so much as to breathe too loudly. The class went silently back to work, petrified of what might happen to them if they caused any more disturbance. Ron was both shocked and shamefully grateful that Snape seemed to be too intent on trying to kill Harry with his eyes to than to hex the redhead into oblivion for causing sizable damage to the desk with his botched potion.

The next fifteen minutes were the longest of Harry's life, he wanted nothing more than for this lesson to end so he could escape and die. Maybe blowing the classroom up wasn't such a bad idea after all.

When the bell finally rang, there was an urgent mass exodus for the door, everyone desperate to be out of Snape's sight while he was in such a dangerous mood.

"Potter, stay behind," Severus called over the noise of fleeing students, and Harry's heart sank. He was in for it now.

The Potions Master approached him as the last student made it to the safety of the corridor and the door swung shut, sealing Harry to his fate.

"What, in the name of Merlin, where you thinking?" Severus wasn't shouting or towering over him, but Harry still shrank back. Severus was angry, and Harry feared that he was going to lose more than he ever had before.

"I'm sorry, I don't know what happened. It just slipped out," he told his shoes.

"Anymore slip ups like that and we'll be in serious trouble," Severus' voice was a deadly hiss.

"I know." Head bent, shoulders slumped, Harry looked truly miserable.

Severus noticed because his expression softened. He didn't want to upset the boy, he just wanted him to understand that they had to be extremely careful in public. He never wanted to lose this infuriating, perplexing and annoyingly cheeky individual who made his life complete.

He sighed softly. "Judging by the way your classmates ran for cover and left you for dead, I think our secret is safe."

Harry just nodded, too ashamed to meet his lover's eyes.

Severus wondered when exactly had he gotten so soft that he couldn't bear even the smallest hint of real sadness on Harry's face.

"Well, you've got a month's worth of detentions in which to learn your lesson," he said in his silkiest voice.

A blush spread across Harry's features, he knew what that tone of voice meant.

When he finally lifted his gaze and met a pair of smouldering black eyes, his blush deepened, he knew what that look meant.

Severus waved his wand at the door and it locked with a definitive click.

"Um, professor?"

Now he addresses me correctly, Severus thought, fighting the urge to roll his eyes.

"Yes, Mister Potter?" Severus replied, advancing slowly on his student like a graceful panther towards its helpless prey.

Harry literally didn't know what to do. Severus had never behaved this way in a classroom. Sure the door was locked, but they'd had an extremely close call earlier.

His mind was telling him he should back away, leave and go to his next lesson before anyone began to wonder where he was. But his body refused to listen. It rooted him to the spot as his professor stalked closer and closer.

While Harry stood immobile and indecisive, Severus took matters out of the Gryffindor's control.

Sliding a hand around the back of Harry's neck, he brought their lips together in a deep kiss, caressing the other's tongue with his own and making Harry's knees go weak. They really shouldn't be doing this, not here, not now. But right now that didn't seem like a strong enough argument for Harry to try and stop him.

Severus carefully pushed Harry back against one of the desks, aligning their bodies and kissing him so intently that Harry forgot what had happened, forgot where they were. He even forgot how to breathe. His body reacted readily and he grew dizzy with want and lack of oxygen.

It was so unfair, Harry thought distractedly, how easily Severus could make him aroused. A look, a spoken word and a kiss, and Harry was putty in his skilled hands every time.

When their lips finally parted, Harry gasped for air and Severus smirked down at him.

"You'd better get to your next lesson. Transfiguration, isn't it?" He asked, still using that devastatingly sexy tone of voice.

Goosebumps broke out across Harry's skin even as his jaw dropped. It was possible that Severus had gotten caught up in the moment and had just regained his senses, but with that much too innocent yet smug look, Harry didn't believe it for a second.

Before he could form a response, Severus had guided him to the door with a gentle hand on his shoulder.

"Remember, eight o'clock. Don't be late," he said, giving Harry's shoulder a slight squeeze before pushing him out of the door.

Evil Slytherin git! Harry thought indignantly, trying to shift his robes to hide his 'problem'. Stumbling away from the dungeons, blushing, panting and flustered, Harry wondered how long it would take before he was fit to face Professor McGonagall.

Severus was so going to pay for this.
