Lightly padding through the dark hallway Hermione began to prepare a litany of spells. She went over the list again and again to make sure she would be prepared for any eventuality. Glancing down at the map again she found Draco still in the bathroom on the 1st floor. She frowned to herself. Maybe Harry is right. He is acting weird this year.
"Well at least it makes him easy to get to" she thought as she smiled to herself. As she reached the door she prepared herself. Casting a charm to ensure it would muffle the sound of the door opening she slipped through the tiny gap not wanting to take anymore risks than necessary. Keeping to the shadows on the far side she spotted him standing in the middle of the room. His back was to her but she knew it was him. Hardly anyone had his telltale
hair. And as far as she could tell no one had those excellent shoulders. Shivering in pleasure at the thought of running her hands across them she silently drew her wand. With a deep breath she began to cast spell after spell. Before he knew it Draco was in a modified full body bind, blindfolded and gagged. The door was magically sealed behind her and the lights dimmed. She levitated him slowly off the floor and turned him to face her. Slowly strutting forward in pleasure and anticipation she watched as he fought against the spell binding him.
No matter how strong he was it should last quite a while. She could always rebind him if necessary but she took the precaution of disarming. She took her time running her hands up and down his robes to find his wand. She could feel his hard lean body beneath the robes and it excited her.

Moving him over to the wall she removed opened his robes and the shirt beneath. Stepping back she took in the sight of his pale creamy skin and his well defined stomach and chest. She leaned in towards him and kissed his neck and began to let her hands roam around his body. He had struggled slightly before, as much as he was able to within the confines of the spell, but now he was tense and still. He obviously wasn't sure what to expect so she didn't take long in putting him out of his misery. Running her hands to his belt she undid it and slid her hands down his body as she dropped into a crouch.

Pulling his boxers down around his legs she paused a moment. She had always thought that maybe it would be a stupid fantasy and he would be like every other boy. But looking at a cock as thick forearm and at least 9 inches long she was a little taken aback. Even at her best she had never summoned a cock that size before. Still she wasn't displeased. If anything the thoughts of it gagging and choking her as she tried to take it made her even more excited.
Enough imagining. Leaning forward she gripped his cock with one hand and lifted it. Starting with his equally large balls she ran her tongue up along the underside of his cock till she reached his head. He let out a little moan at that. She grinned as she opened her mouth wide and began to suck his cock. It didn't take long before it started to hit the back of her throat and she began to struggle. She could remove her gag reflex of course but where was the fun in that so soon.

No for now she just enjoyed feeling his cock force her throat open as she began to bob her head up and down on it. She placed one hand on his balls as the other began to stroke up and down his cock in time with her mouth. She could feel her pussy getting wetter and wetter as she continued. This couldn't have worked out any better! She started the moan around his cock as she sucked it harder and harder. He seemed to enjoy it so she moaned harder and longer as she started to swirl her tongue around the tip of his cock before plunging it back down her throat again. Her eyes watered and she began to make obscene gagging noises.
That was all Draco needed and she felt his cock twitch and begin to spurt into her mouth. She could taste his hot salty cum on in her mouth and she loved it! She licked and sucked all over his cock making sure to get every drop she could. She sat back on the cold ground and caught her breath for a moment. Looking up she admired her handwork. His cock had gotten smaller and was twitching and throbbing away as she watched fascinated. She couldn't believe how turned on she was by his cock.

Getting back into position she got onto her knees this time. She wanted to have a little fun herself before she finished up with him. Drawing her wand she summoned a cock beneath her. Lowering her pussy onto it she began to rock forward and backwards feeling it spread her pussy. She lifted his cock with her hand and began to nuzzle and suck on his balls. He definitely enjoyed that because as she used her other hand to stroke his cock she felt it getting hard again. Bouncing up and down she increased her tempo faster and faster as she stroked his cock harder and harder. She knew what he would think of her if he could see her now.
Mudblood! She felt a thrill run through her. Whore! She shivered with pleasure. She could practically here him calling her obscene names as she licked his balls over and over. She began to cry out at the thought of riding this monster of a cock. But no she had no time. It was late as it was and she had pushed her luck tonight as it was. Settling for him cumming on her face she began to stroke his cock has hard as she could. She writhed up and down on the cock below her in the meantime. Muttering a quick spell she felt the cock increase in size and length. She cried out as it swelled inside her with a sharp pain. But it wasn't long before it turned to pleasure.
Forcing herself to slam it deeper and deeper into her pussy she began to tremble. She was on the precipice of an orgasm when she felt his cock throb in her hand. She pointed it directly at her face while she continued to stroke and immediately had a mind shatteringly good orgasm. She felt him unload onto her, his cum ruining her makeup and smearing on her lips and chin. It dripped down onto her chest soaking her robes. She cried out again as a second orgasm hit and fell onto her back below him. He was still shooting small spurts of cum that landed on her chest and stomach as she lay there dazed beneath him. The back to back orgasms had left her feeling exhausted.

It was all she could do to reach for her wand and cast a spell to clean herself up. She sat up slowly looking all around. "Time to leave"; she thought to herself. Standing she picked up the map where it had fallen loose turning her back on Draco as she did so. Her back stiffened as she heard a whisper of cloth behind her. Slowly turning she saw Draco struggling free of the body bind curse. He already had one hand loose and had grabbed the blindfold. With a scream of terror she turned and ran for the door. She pulled for a few seconds before she remembered her spell. Not bothering with the counterspell to unlock it in her panic she simply blasted it open. With one last fearful look into the room behind her she met his eyes
"He knows"; she thought.

And soon the whole school will know...
