'This is perfect,' thought Draco, 'aha, this gets the prat back for watching me.' Just then a thought hit Draco. "AHA, oh please be true." Draco said aloud to himself as he rummaged through the dormitory to find his book. After quickly skimming through the pages he found the page about the curse he had used on Harry. "Here it is, 'Erecto' This curse was originally designed to erect buildings, tents etc… blah, blah, blah. With a simple change in wrist work you can cause the target of your choice to gain the hardest erection they have ever had, blah, blah, perfect for humiliation, blah blah. Oh my god just get on with it! Hmm, ah here. Unless the target knows the counter-curse nothing else can reverse the effects of 'Erecto'. Note- If the receiver of this curse tries to use more 'pleasurable' ways to reverse the jinx it will only make the effects worse causing their problem to become harder if you'll pardon the pun." Draco started laughing uncontrollably at this, it was too good to be true, Harry would unlikely be running to Madame Pomfrey with this which would only mean he would have to ask Draco for help. Draco had Harry in the palm of his hand, not literally of course.

*********************

The dinner could not have gone slower for Harry, not to mention more embarrassing, how could he look Mcgonagall in the eye again? Anyways Harry could forget her now, he was alone in his dorm and needed to get rid of his erection. He lay back onto his bed and pushed his trousers and boxers down. Harry reached over into his bedside cabinet to pull out some lotion then set to work on getting his dick down.

After about three quarters of an hour of wanking the only results he had gotten was an even bigger erection, not to mention every time he stroked his dick it left him just balancing on the brink of coming and he just couldn't come off (no pun intended). Harry gave up in a huff, even with lotion his hand was hurting, not to mention the muscles in his arm that had began to ache. There was only one thing left he could do and even though he had realized this about fifteen minutes ago he was still reluctant to go along with it. But with the ever increasing of size in his erection he gave up all hopes of dignity and pulled his pants back up.

Five minutes later Harry was fully dressed and had written a note which was on its way to Draco, the holidays made it so much easier to send notes around the school as he was allowed to keep Hedwig in his room and she was always good for company. The note itself was quite short just saying,

'Pervert, I know it was you. Meet me in the old potions class on the east side of the castle in half an hour. I know threats won't work because I know that you know that I don't need a reason to hex your bollocks off and that this just makes it easier but if you do I'll give you what I took back. Potter.

Harry knew that this would work and was confident that he would show so Harry grabbed his wand and set off to the abandoned potions classroom, which he had chosen to be on the opposite side of the castle so as not to arouse any suspicions that Harry knew about Draco's little alone time, to wait for Malfoy.

*********************

Draco was cheerfully sitting in the Slytherin common-room when a snow white owl tapped on the owl portal, he smirked as he walked over to it. Who didn't know whose owl this was and Draco had been waiting for it since the dinner. Draco was surprised it had taken Potter this long, it was already 10 p.m. A gust of icy wind accompanied the owl in as it swooped over and landed on the table in the middle of the room. Draco shivered and then went over to detach the message from the birds leg.

A confused look set into Draco's face as he read the note, 'What in Meriln's beard could Potter have?' he silently asked himself. 'Oh well, might as well see what more I can do to mess with Potters' empty head.' Draco put on a warm robe and set out to find the old potions class Potter had chosen for them to meet, not missing the fact that he chose the opposite end of the school from their first encounter of the holidays.

As Draco approached the classroom door he quickly brushed down his robes, pushed back his hair and set his usual face. Then he pulled open the door and set eyes on a messy as usual Potter sitting casually on one of the desks with his knees drawn up to his chest. Draco walked over purposely taking his time, just to make Harry that bit more uncomfortable. Harry had turned to look at the door as soon as it had opened and his face was a familiar look of disgust and hatred that Draco had grown accustomed to every time the boys set eyes on one and other. Harry quickly got up, not caring that the bulge in his trousers was showing. "Malfoy!" He spat, "Reverse it, now!"
"What have you taken first, Potter?" Draco spat back with as much distaste as Harry. Harry's eyes flitted over to a small box, wrapped in brown paper on one of the desks at the desk he was previously sitting at. Draco noticed the sudden movement in Harry's eyes and turned to retrieve the box.
"Don't bother Malfoy, You really think that I'm thick enough not to charm it? You can't lay a finger or hex on it until you reverse this curse." Harry replied, his hands gesturing to his crotch. Draco smirked and almost laughed.
"So it worked then. Looks like you tried to get rid of it yourself." Draco snorted. Harry sent him another glare of death before Malfoy continued.
"Are you sure you want me to? Mcgonagall seemed pretty intrigued with my little jinx."
"Reverse it now you stupid prat!" Harry yelled not so loud to draw any attention from outside but loud enough to try to be threatening.
"I'm not doing anything until you tell me what's in that box." Draco replied coolly.

*********************

During this whole commotion, neither boy had noticed the silent ghost who had decided to pop in at the sound of raised voices in the night time. A wicked grin set on his face as he slowly drifted back through the wall. Only to return a few minutes later in one of the darkest corners of the room, fully happy to watch the events.

Harry turned to face the plain looking box at the side of the room as he did the face of his glasses seemed to fog up. He took the off while turning back to the now more agitated Malfoy and rubbed the glasses clean on his shirt. When he put them back on the fog was still there but it seemed to be more around the room than he had previously thought. When Harry dragged his eyes back to Malfoy the mist seemed to have swirled around the other boy who was now looking more confused and skeptical. But after a blink of an eye all the fog was gone, leaving two very confused boys standing around looking accusingly at the other.
"What are you up to Potter?" Draco shot venomously.
"That wasn't me." Harry responded defensively.
Harry blinked again but this time when he opened his eyes the world was still black. Harry shook his head in confusion and clamped his eyes shut. When he opened them back up again, things had changed. Everything looked different. Everything.
