Chapter Text
Draco drummed his fingers against the desk, rereading the same line he had been reading for the past twenty minutes. The others had only left less than a few hours before, but he already felt sick with boredom, the words of his textbook seemed as foreign to him as Parseltongue as he tried to get the information to sink into his brain.
His decision to stay at Hogwarts over winter break was, truth be told, not his decision. All packed up and ready to go, his eagle owl had flown in through the window not more than an hour before the Hogwarts Express was due to take him home, with a letter from home telling him that his father had sudden urgent business and his mother was also rather busy with 'something' so it was best for him to just stay behind.
He had shrugged it off casually, Blaise and Pansy eyeing him up for a reaction, but admittedly he was disappointed not to be home over winter break. They didn't celebrate Christmas, so there was no loss there, but he did miss his mother even if he would never say it aloud because wouldn't that be embarrassing?
There was only one other Slytherin that was staying behind over the holidays, and that was you. He had overheard you mentioning having the common room to yourself and made some remark that earned him the finger, and then Blaise had implied that maybe your 'stupid blood traitor brain' could be fixed if you just had a good wank and Draco had laughed half-heartedly because, as much as he liked to pretend he was a suave womaniser, the reality was that he had grown up in a conservative household and the idea of sex and women were actually quite baffling to him.
Draco wondered, frowning at his pillow, whether or not you were in the common room now. He doubted you knew about his change of plans and he was sure you would be annoyed to discover your alone time was ruined. Yes, pestering you would be more fun than sitting there, alone and lonely. He picked up his books to create the illusion he wanted to study in the common room, not just to talk to you. Irritate you, that is.
He was halfway down the steps when he heard a noise, muffled through the wall, but unmistakable. Crying? Screaming? His hand hovered over his wand as he considered turning on his heel and bolting up to his dormitory. Then there was another sound.
"Fuck," you cried out.
He knew it was you because no one else was there and he recognised your voice now, sort of. You sounded different. You voice was raspier, lower, and it sounded as if you were panting.
Slowly, he crept down the last few steps and peered his face out from the wall to see. His breath caught in his throat at the sight of you, naked bar a pair of black lace-trimmed panties which you had your hand in and seemed to be touching yourself under.
Draco watched, fascinated as your other hand moved to your breasts, squeezing playfully. Your moans got louder.
An uncomfortable bulge formed beneath his trousers and he realised how much he was aching, watching your body in the flickering light of the Slytherin fireplace. He palmed himself through his trousers, but it wasn't enough. Quickly and quietly, he undid his black belt and pulled himself free from his restricting pants.
Slowly at first, he rubbed himself to the sight of you, your back arched, and chest rising and falling with every deep breath. He watched as your hand increased speed and he copied, going faster on himself. He put one palm to the wall to brace himself.
He pressed his lips together, not letting himself moan in case you noticed him and, Merlin, this was so wrong of him...
He watched your body convulse as you let out one final cry, and your body went limp. He couldn't make out your face very well, but you threw your head back in pleasure. Seconds later, as he bit down hard on his own lips to prevent himself making any noise, he came hard, his hot cum spraying the Slytherin walls.
Draco looked at it for a moment, trying to remember the spell he used to clean such things, but his mind felt foggy and he just wanted to collapse. With a moment of relief, he remembered the charm and pulled out his wand to whisper the incantation.
"Hello," you called, your voice high with panic. "Is someone there?"
You wrapped your robe around yourself hurriedly and poked your head up the staircase, but Draco was already gone, back sliding against the door and asking himself if he imagined the whole thing.
