The rest of that day was pretty uneventful. Both boys had retired up to their common-rooms, Draco was mulling over what effects his little show could have on Harry while coming up with more ways to mess around (some habits die hard) and Harry was practically pulling his hair out over what in Merlin's beard was actually happening. But aside from a lot of thinking and lolling about in dormitories nothing really important came up that day and the time just drifted past.
It was coming up to dinner now and Mcgonagall had told Harry that as there was only a few teachers and only two students they would all be eating at the head table in the Great Hall. This became apparent as Harry walked in to the Hall to find all four of the house tables evidently missing from their normal spots making the Hall look three times bigger than it normally did. Nothing else had changed though apart from the tables, the ceiling was still enchanted and was a beautiful sunset sky with just a hint of red glowing on the clouds and the candles were still hovering over nothing now. It made the room look rather funny. The sight of about seven teachers and one student sitting at a grand table at the back of an empty hall filled with floating candles that were hovering mid-air was definitely not something you'd see every day.
Harry swiftly moved up and took his seat at the table, he was placed on the end but sitting next to Mcgonagall and across from Draco Malfoy. It had apparently been her idea to shrink the table so the remaining people could chat easily but that wasn't the smartest idea, not with Harry and Draco so close. The presence of the teachers so close stopped any thought of verbal contact with the other boy but neither liked the situation and it was only a matter of time before something would happen.
True enough it was only five minutes since the food had arrived that the mischief had started. Draco had spent the whole day re-reading a book (which he would never admit he had bought or even owned) from 'Weasley's Wizard Wheezes', it was called '101 new jinxes- a book on never before seen jinxes for mayhem at school.' and had proven to be quite useful to Draco for the first half of the year already and he had the perfect jinx in store for tonight.
Harry had sat with his hands in his lap, it is rude to have your elbows on the table as his aunt petunia had drilled into him throughout his years at pivot drive, and so only moved them when the food had arrived, Draco leapt on the opportunity. He himself had kept his hands in his lap as he had been brought up with all the respectable graces of a noble but tonight he had purposely set everything up, it would look suspicious to suddenly reach for his wand in the middle of dinner with Hogwarts professors. Draco had been practicing this particular spell all day and seeing how he knew the counter charm he tested it out on himself once he was sure he had got it, just to check if it worked, not for any other reasons just to test it he had told himself, it wasn't just curiosity, but anyway the fact is he had learned it backwards and could even cast it silently now.
Draco waited until the perfect moment and then he struck, reaching slowly and carefully for his wand so as not to draw to much attention to himself and when it was safely on the side of Draco's leg he silently cast the jinx on Harry and waited for the effects to show with a slight smirk on his face.
********************************
Harry was happily eating his meal, still a little cautious of Draco but to Harry's surprise he had barely even acknowledged his presence, which was fine by Harry as he would do the same. It was when Harry reached across the table to begin piling the roasted potatoes onto his plate and felt a warm tingle run up his thigh that he started to believe something was going wrong.
Once Harry was satisfied that he had filled up his plate so as to gorge himself for a good sleep afterwards did Harry finally look down to check his legs and see what was going on. Nope, Harry's legs were perfectly normal, oh but if you looked a bit higher up you would definitely get a good eyeful.
Harry's eyes bulged at the bulge that was still growing in his groin. By the time the warm tingle had subsided in his thigh, his dick was at full hardness in his trousers and the bulge was unmistakeable. 'Oh fucking God!' Harry thought, 'Fuck, why is this happening? God! why did I have to go commando! Fuck!' Harry realized his thoughts must have been reflecting on his face as Draco started snickering. 'You! It was you! You bloody wanker!' Harry thought or rather screamed in his head. But what happened next really did plop the cherry on top for Harry. As quickly as he could Harry pulled his robes to bunch up at his crotch, in an attempt to cover the bulge but he wasn't entirely quick enough. Well not before Mcgonagall had received an eyeful herself of Harry's problem. Her face twisted into an unreadable expression, Harry noticed this and groaned inwardly, this really was the last thing he needed. When Harry glanced out of the corner of his eye to look at the professor again her face had turned into another expression Harry couldn't make out but he could decided what it was close to. It was either her face of 'Oh-my-gosh-the-student-next-to-me-has-an-erection -how-utterly-disgusting-ew!' or even worse a face of 'oh-my-the-student-next-to-me-has-an-erection-how- interesting.' Harry didn't know which was worse, but he could more than likely guess.
Harry had no idea what he could do! If he got up now to leave the whole table would get en eyeful of his crotch and if not press questions at his sudden departure after only just arriving. He can't yell or get Malfoy back as the professors would become suspicious of his sudden outburst. 'Ohhh! You've planned this well haven't you, you blood ferrety prick!' Harry thought to himself as he looked over to Malfoy, who was sitting with his face down, shoulders jumping in his obvious attempt to laugh silently. If a glare could kill, Draco would have been killed forty-nine times, revived forty-nine times just so he could kill him again the fiftieth time. But Harry settled for a rather painful kick to both legs, causing Draco to jump and hit his knees on the underside of the table. Professor Slughorn jumped beside him also at the sudden movement. "I say dear boy, We aren't boring enough to make you doze off are we?" He said with a twinkle in his eye and a playful laugh in his voice. At this the rest of the table just laughed, Draco kept his face uncaring of the matter but held a sneer for Potter for when the teachers returned to their conversation.
