The spoilt milk-filled rubber sack was kept in the pocket of Draco's school robes all through defense against the dark arts Thursday morning, while he waited for the perfect time to hit Harry. Professor Snape was letting him get away with this, so he wanted to disturb the class as little as possible, which meant waiting until the end. And he didn't want to splash anyone else with the spoilt milk, or it might get out that it was milk and not bubotuber pus in the sack.

Draco worried that Professor Snape would have them practice dueling today and that the sack would leak in his robes and stink, but that fear turned out to be unwarranted, because Professor Snape stuck to lecturing. Draco found defensive theory boring and although he knew he needed it, he almost fell asleep in class half a dozen times, but he caught himself and forced his eyes to stay open. Draco watched the clock and fiddled with his quill and waited.

And then the clock indicated that there were only five minutes left in class and Professor Snape called Harry to the front of the class to help with a demonstration. Draco was sitting in the front, while Harry was in the back today, so Harry would have to walk right past Draco's desk to get to the front. Draco reached into his pocket and fingered the thin sack in anticipation of the opportune moment and then the moment was there and Harry was just steps away. He pulled the out the sack as he stood and threw, hitting Harry square in the forehead right when Harry came level with Draco's desk.

Harry didn't know when Draco was going to prank him with the milk and certainly wasn't expecting it at this moment. Class was almost over, so maybe Draco would hit him in the hallway after class, but surely Draco wouldn't do it front of Snape! But Draco had done it right in front of Snape and Harry was spluttering as the chunky spoilt milk flowed down his face and dripped off of his chin, making little splatting noises when the drops hit the floor. It smelled atrocious and a little bit dribbled into his mouth, making him gag and spit it out, adding to the mess on the floor.

Only then, after he spat, did Harry remember that the substance was supposed to be bubotuber pus and was supposed to burn. He faked a scream and shouted frantically, "It burns! It's burning!"

Draco smiled as he saw the look of shock on Harry's face, knowing that he had managed to get Harry by surprise even though he had warned Harry that it was going to happen. When Harry spat, Draco took in a great big breath and let out an enormous laugh and the rest of the class joined him in his mirth and frivolity. The entire class broke out into very loud raucous laughter, but then Draco smelt the spoilt milk and started gagging and heaving.

Draco put both hands to his mouth and tried to stave off the heaves, but he couldn't and was soon emptying his stomach onto the floor of the defense classroom in front of half of the sixth year students and Professor Snape. As he puked, his eyes drifted over the room and he noticed that everyone was looking at him while they continued to laugh at Harry. Draco heard a few gasps as he lowered his head in embarrassment and continued to hurl.

Harry saw Draco puking right in front of him and he wanted to help, but he didn't have any crackers and he wasn't supposed to be seen helping Draco, plus he was supposed to be burning from the fake pus. Harry scratched at his face with his left hand, raking his nails down his face to redden the skin and make the ruse more convincing, while he grabbed his wand with the other hand and vanished the milk, vomit, and spit from the floor and from his face. Even if he couldn't go to Draco's aid, he could at least remove the source of the problem.

Professor Snape stood in the front of the room as he saw the scene unfold. He called Harry to the front of the room to give Draco the chance to play his prank at a time that was convenient for him and it had worked. Professor Snape determined to stand back and out of the way until the scene played out and that worked at first, but then Draco started vomiting. This was bound to happen sooner or later, so Professor Snape had previously looked up the recommended treatments for morning sickness. He put that knowledge to use now.

Professor Snape went to his desk and removed a potion for morning sickness and transfigured his coffee cup into a basin to catch the flow of vomit. He rushed to Draco's side just as Harry vanished the mess. He shoved the basin under Draco's mouth.

Draco, relieved help was finally here, grabbed onto the basin and held it for as he hurled. Draco made eye contact with Professor Snape as the Professor brought forward the potion vial. Professor Snape gently reached out for Draco's head and guided it backwards as he pressed the potion to Draco's lips.

"Drink it, Mr. Malfoy," Professor Snape instructed. "It'll stop the vomiting."

Draco swallowed it down quickly, trying to hold back another violent lurch of his stomach. Some of the potion dribbled out the side of his mouth with the heave, but he swallowed again and the rest went down, calming his stomach immediately.

Professor Snape took the vial back and pulled out his wand to perform a cleaning spell on Draco, to remove the potion that didn't make it down, as well as the vomit splatters that Harry had missed. "Are you feeling better, Mr. Malfoy?" Professor Snape asked.

Draco nodded, not quite recovered enough to speak, and sat back down in his seat. He noticed then that the laughing had quieted down and was replaced by the loud insistent chatter of the other students. Harry was still standing in front of him, watching him and although Harry had red scratch marks on his cheeks, he had apparently forgotten to continue screaming.

"Harry, we have to get you to the hospital wing. I think that was bubotuber pus you got hit with!" Hermione said, jumping to the rescue. Harry had told her the night before of Draco's warning and now that Harry seemed to be more interested in Draco than his own fake injury, she stepped in to get this fight back on track.

"Yes, Ms. Granger, please take Mr. Potter to the hospital wing," Professor Snape replied.

"Come on Harry," Hermione said, stepping forward and taking Harry's hand to pull him along and out of class. She had her backpack on one shoulder and Harry's backpack on the other and as they walked, she handed Harry's backpack over to him.

"Class dismissed, move along everyone," Professor Snape called and the students started filing out, but many lingered to watch.

"Professor Snape, aren't you gonna give Malfoy detention for hitting Harry with that pus?" Ron asked. If Harry asked, Ron would say he did it to keep up the ruse of the fight and detract attention from Draco's vomiting, but secretly, he wanted to get Draco in trouble just as much.

"I will deal with Mr. Malfoy as I see fit, Mr. Weasley. I suggest you move along," Professor Snape said, before turning back to Draco.

"Do you think you can go to your next class now, Mr. Malfoy?" Professor Snape asked.

"Yes sir," Draco replied, stuffing his school things into his bag.

"You will have one night's detention for disturbing my class with your childish pranks. I will let you know when you are to serve it," Professor Snape said.

"Yes sir," Draco replied. "Can I go now? I'm gonna be late to class," Draco replied.

"Yes, please go and take the rest of these looky-loos with you so that my next class may come in," Professor Snape replied. At least half of the looky-loos were Slytherins who were certain to follow Draco out the door. "And happy birthday, Mr. Malfoy."

"Thank you, sir," Draco replied and quickly exited the room. Greg, Vince, Pansy, Theo, and Blaise were all waiting for him silently at the back of the room and they went out ahead of Draco.

"What happened?" Greg asked as Draco exited the classroom; Greg sounded concerned.

"Yes Draco, do explain why you started vomiting when it was Potter that was hit with the bubotuber pus," Pansy demanded.

"And bubotuber pus doesn't even cause vomiting," Blaise added.

"Well it's disgusting, isn't it? It was dripping down Potter's face right in front of me," Draco defended himself as he guided his friends along to Ancient Runes with him. Some of them had a free period instead of the class, but if they wanted to talk to him, they had to walk with him.

"It was rather gross. It looked all lumpy," Crabbe said. Crabbe and Goyle had been closest to Draco during the incident, so they had the best view.

"Plus, it smelled like petrol. I've always hated the smell of petrol," Draco lied.

"Since when? You were fine in herbology two years ago when we first extracted bubotuber pus," Pansy retorted.

"Since last summer. My crazy Aunt Bellatrix stayed a good part of the vacation with mother and me and she smelled of petrol from all her time in Azkaban. I suspect it had to do with all of those years of poor hygiene that prison life instilled in her," Draco lied. His aunt hadn't smelled, but she was crazy enough that people would believe anything of her.

"Cousin Rodolphus and his wife stayed with my family for a bit and they didn't smell," Pansy objected, but they were already outside the ancient runes classroom and Draco, Greg, and Theo were already going inside to take their seats next to Millicent and Tracey. And since Pansy wasn't in this class, she was forced to stalk off back to the dungeons with Vince and Blaise, despite her personal knowledge of the Lestranges, thanks to her mother being first cousins with Rodolphus; sure they were psychotic, but they didn't smell.

Despite throwing up minutes before class and not having a chance to eat his usual snack, Draco felt fine during ancient runes, thanks to the potion Professor Snape had given him. Afterwards he went to lunch and every time someone brought up his puking, he switched the subject to the look on Harry's face when Harry got hit and speculation over how badly Harry was hurt. Harry wasn't present at the Gryffindor table, so Draco played it up, insisting that Harry must still be in the hospital wing, being treated for injuries. Draco figured that Harry was just skiving off lunch in favor of raiding the kitchens, but he still used it to his advantage.

After lunch Draco shook off Pansy, Crabbe, and Goyle in favor of going to the room of requirement. Pansy protested saying, "But Draco, I wanted to speak with you about something."

"Sorry, I've got to work on my Death Eating project or the Dark Lord will have my head," Draco lied, before continuing on without his friends. Mentioning his involvement with the Dark Lord was normally enough to get his fellow Slytherins off his back about anything, because they all understood how critical it was to please the Dark Lord.

Draco was somewhat concerned with being caught in the room by Harry, which is why he chose to go now, while Harry was in herbology class; it was the only free period Draco had that Harry didn't. He opened the door and found the room how it had been before the near miscarriage. The hut was smaller again, clearly indicating that the extra bedrooms were gone. He went inside the hut to check if the rest of the hut was intact.

Draco was relieved to see that the nursery was still there and the study had returned to its original size, now that the second hallway was gone. But he didn't want to study or play in the nursery, so he put his school bag down and went into the beach bedroom. This room held a lot of memories of Harry, which he tried to block out, because he was determined not to think about Harry when he did what he needed to do.

Draco needed to wank. It had been two days since his last wank, which hadn't left him fully satisfied. He required the room to provide him with some pornographic material for his wank and it did. But during the course of things, he began to fantasize about buggering Harry, closing his eyes and completely forgetting the porn.

*Censored

Sleep came quickly to Draco. He woke up in the afternoon covered in dried cum, which he found highly disgusting. It made him wish for Harry, who cleaned such messes up before Draco could be bothered by them. As it was, Harry wasn't there, so he had to go into the bath to clean up. Harry also wasn't there to rub Draco's back for him and hadn't been all week, so he took the opportunity to lie back in the hot water and relax in the giant tub. As he did so, he thought about how he had once again failed to not think about Harry during his wank. Eventually he concluded that it was time he forgave Harry and let Harry wank him again. He was still annoyed at Harry, but he didn't want to punish himself while he was punishing Harry.

When he finished his bath, he raided the icebox for his snack. He ate and then went to the study to work of his history of magic project.

While Draco was in the study, Dobby appeared with a large package and said, "Dobby is to be giving Draco Malfoy, sir, this present, sir, from Narcissa Malfoy, ma'am."

"Alright, give it here and you can go," Draco replied, taking the present from the elf.

Dobby left and Draco opened the birthday card that was on the top of the present. In the card his mother wished him a happy seventeenth birthday and promised they would celebrate it properly later, but for now this present was the best she could do. Draco removed the shiny silver paper and revealed a large box filled with cans of assorted flavors of macadamia nuts, real macadamia nuts, not the fake ones from the room, and a small black box. When he opened the small black box, he found a tear shaped pendant with swirling silver, blue, and bronze liquids inside. There was a note with the pendant, which said it had a shield charm on it, that would protect the wearer from a wide variety of hexes and curses and that it had belonged to his grandfather, Cygnus Black.

Draco put on the pendant and ate a few of the nuts, storing the rest in his school bag. He wrote a return letter to his mother, which he stopped by the owlery before dinner to deliver. Dinner was a cheerful affair, with everyone still excited about the prank they had pulled on Harry. After dinner they went back to the Slytherin common room and celebrated Draco's birthday. It wasn't brilliant, because it was a school night and they had homework to do, but it was the best his friends could do.


Author's Note: So what did you think of Draco's prank? Should Draco have tried to do more to stop it, or did he do enough?
