A couple of minutes had passed since Draco had started his fun in the abandoned classroom he was now lying on his back with his trousers around his ankles rubbing at his erection, a quiet creak of the door caught Draco's attention. Draco pretends to not hear it, I mean who else could it be? No matter who it was, unless it was Snape, no one here would stop him from his fun. Malfoy continued rubbing his crotch through his boxers. As the door opened and silently closed a little, not completely, Draco heard a soft intake of breath. He could see a now visible leg at the door, 'Obviously the prat hasn't realized.' Draco thought. Harry's cloak was slightly caught on the door and was revealing the unmistakeable trousers of the boys uniform. 'Hmm, let's see how prissy the great Harry Potter is.' Draco thought, smirking on the inside, careful not to show Harry he knew he was here. 'Aha, I know.' The leg was now just starting to turn when Draco pulled out his long, hard cock. Quite a few times Draco had seen other boys in Slytherin comparing their dick to his, Draco knew he had a larger than average cock and he was, obviously as a boy, proud of it, but never in his life had the sight of his cock caused anyone to stop in their tracks completely. Draco wished he could see the look on Harry's face right now, if he had to guess he would have said dumb-struck confusion. Draco's hand now pumping rhythmically up and down his length, his hands roaming his body, playing with all the right spots on his body for the show. It's only a matter of time until he realizes what's going on and flees to leave Draco in peace for his wank, is what Draco thought. After a short while Draco noticed that Harry wasn't leaving, 'All right then, you want something to wank about yourself? Why not?' Draco thought. "Mmm, Harry." Draco, looked through purposely half-lidded eyes to catch a ripple of air turn his way. 'Aha, he wasn't expecting that.' Draco thought.
'This is fun, messing around with the chosen ones head.' Draco thought as he was shamelessly moaning like a well paid whore. It was obvious to Draco now that he wouldn't be getting any alone time, so he might as well carry on messing with Harry. Draco's hand was moving faster now, quickly moving up and down Draco's shaft pressing down on all the spots he knew felt good, especially not missing rubbing his index finger over the head. Draco had never had an audience and did it feel different. Wanking was fine on your own, with nothing but your fantasies but wanking in front of someone while they stare at you, this was a new one for Draco. His hand was bringing him closer and closer to completion, when a slight movement from where Harry was standing caught his attention once again. If Draco hadn't had his trained seekers eyes he would most likely have missed the slight movement but when he saw Harry's hand pressing into his crotch, that was not what Draco had expected. 'So you do like what you see, eh Potter?' Even in his mind Draco spat the word Potter. But Draco's mind was quickly pulled away from that thought as the pressure pooling in the pit of his stomach started to to build and in a few more strokes and a loud "Harry, Harry, Oh gods Harry I'm gonna come. Mmmmm, yes Harry like that, Oh my God. HARRRRRRRRRYY!" Draco came, spurting long strings of his seed over his chest. He just registered Harry quickly turning and running out of the old classroom. 'Well, that was fun.' Draco thought as he chuckled out loud. Draco collapsed back on to the desk to get his breath back, that had actually been a good wank, aside from Potters intrusion. After a moment Draco pulled his wand out of his robe and cast a scourgify to clean up the rapidly cooling spunk on his chest and put his clothes back on.
Draco headed back down the corridor, now back on his aimless stroll through the castle. 'What an eventful morning.' Draco thought to himself.
