This is my rendition of Harry Potter and the Half-Blood Prince, from the points of view of several different characters and with added/changed plot.
Chapter 1
Severus
The sun rose brighter and clearer than it had in months that morning, penetrating the mist and then the black curtains that covered each dusty window in his sitting room. But Severus Snape's mind was full of darkness. Too much bloody fog, he thought. It had been like that for months, the Dementors' breath clouding the minds, hearts and vision of millions of people all over Britain. As if that article in the Daily Prophet didn't cause enough panic.
A faint crack sounded outside, far away. Then another. At least the wretches are punctual. As Snape rose to put the kettle on, another noise touched his ear, this time an animal's scream. He hastened at this, shoving the rusted kettle above the flame. If they're going to start killing, they could wait at least a minute.
Peering out his kitchen window, Snape observed two dark, slender figures weaving through the unfortunate mess of brick houses. Spinner's End was not a kind place to navigate, and Snape liked it that way. Surely these two would find him unscathed, but weaker foes would never reach him. He heard rapid footsteps and arguing, too, but made no attempt to discern it. Let them have their petty quarrel, Severus thought. It matters not. Hear their proposal, lead the way as you know they'll let you and accept.
The knock sounded through his heavy door, and Severus cracked it open. A gaunt but beautiful face greeted him. Narcissa Malfoy was of dangerous and treacherous blood, and a more foul disposition was hard to find, but you could not deny how easy to look upon she was. Pale, shimmering hair fell down to her back along a face riddled with grief and worry, and almost more gorgeous for it. Nearing forty her form was aged, that was obvious, but how shapely she was now only stood as a testament to her youth. Narcissa had firm, full breasts that stood out even under the many layers she'd donned to fight the cold mist. Her hips curved dramatically at her waist, framing a supple ass that begged to be taken in two handfuls. Far more than Lucius deserves, Snape thought, glancing at her.
"Severus," she said under her breath. "May I speak to you? It's urgent."
Snape ushered them in, nodding stiffly at Narcissa's sister as she passed. Bellatrix had an entrancing way about her as well, but one of reputation, not beauty. Her nose was droopy and long, her eyes shadowed by decades of Azkaban and her dark, filthy hair hung to her waste in knots and tangled ribbons. Snape eyed the long, dark wand she was brandishing, still alert from the noisy business outside. The things that wand has done, Snape thought darkly. As merciless than she is insane. I would be doing half the wizarding world a great service by snapping it and killing her right now.
But that would have to come later, Snape decided, and he offered them tea cheerily.
"Wine." Bellatrix said, more a statement than a request.
After Wormtail fetched them the wine, flinching at every sideways glance by the witches, Severus heard them out. First from Bellatrix came the questions, accusations of treason against Voldemort. He did his best to appear surprised at every new question or revelation, but truthfully he had rehearsed the conversation at length in his mind. As he told them, if had no sufficient answer to any of these questions, the Dark Lord would have disposed of him immediately. When the arguing was done, Bellatrix sat sulking coldly and sniffing her wine. Then came the topic of the boy.
"Severus — oh, Severus — you would help him?" Narcissa implored. Her huge sapphire eyes shone in the dim room. "Would you look after him, see he comes to no harm?"
"I can try. It will be no easy task for me, let alone a teenager," Snape regarded her silently, trying to make out if he gave anything away. "I shall do all I can, Narcissa."
Bellatrix snorted into her wine glass. "A weak promise from a weak man. Make the Unbreakable Vow, or stick your empty claims somewhere else. My sister doesn't ask this lightly."
Severus did his best to seem perturbed, which gave Bellatrix a satisfied smirk. This was Lord Voldemort's right hand?" Snape sipped from his wine glass.
"Very well," he said finally. Bellatrix exhaled sharply and her sister squeaked. "I would even ask you to perform it, Bellatrix. Right here, in the room we sit."
While Bellatrix gaped, Narcissa rose quickly and embraced him. It was brisk at first, but she loosened in his arms and he felt her tits press softly against his robed chest, her warm loins brush his. He filled his nose with the smokey smell of her hair and suddenly felt his cock stir. And after, a token of your gratitude, I think.
When the words were said and their wrists had been encircled with twining flames, the sisters said their curt farewells and made to leave. Bellatrix even held his arm and her black eyes seemed less suspicious than they had. Snape strangely felt calm. The implications of what he'd done were clear to him, but he did not feel anxious or regretful. Only hungry.
As the door swung wide and Bellatrix hurried briskly out, Severus caught Narcissa's wrist gently. "One more thing, if you don't mind. Just you." Her sister stared at him carefully for a few seconds, then granted their privacy with a slam of the door.
"What is it, Severus?" Narcissa's face showed confusion. "Is there some flaw here?"
"One more thing," he repeated, his eyes once again taking in her taut body. "I have made the ultimate statement of my loyalty to you and Draco. Your turn. What can you do to prove I made the right choice?"
"Whatever the Malfoys can provide you is yours, Severus. Lucius has mountains of gold in Gringotts, not to mention influence over the-"
"What I desire is not something Lucius can provide," He cut her off. Her eyes showed understanding now, and under that, resignment. Had she known she would have to give herself to him? "Something I haven't had the fortune to experience in many years." That was a lie, but what harm could a little sympathy on her part cause?
She bent before him on the musty, fraying carpet. "You tell the truth, Severus. You have proved much," Narcissa spoke softly. Her hands went to his pants, and she found him already hard. "But only as far as I say."
Severus nodded, and her fingers worked deftly now, tearing down his clothes layer by layer. Finally he was naked below the waist, and she gripped his stiff cock in one dainty, pale hand. Snape was not an attractive man by any means. His hair was greasy and fell lank about his shoulders. His eyes were beady and black, and his nose hooked downward over his sullen face. No woman he'd been with, however, could say his manhood was ugly. Seven inches tall and thick as his wrist at its best, it curved up and up. The flesh was pale and pink, unblemished and covered in handsome twisting veins that made it look muscled. At the top his head stood boldly, purple and slightly more pointed than was normal.
Narcissa flinched a moment when she first saw it in light, but if her eyes told true it wasn't disgust or fear he saw, but her reluctance fading. She slid her smooth, cool palm up and down the length of it slowly a few times, her fingers touching the head lightly. Growing more bold, she added the other hand, and soon was stroking up and down at a brisk pace. He felt his cock swell even more and he closed his eyes, savoring her touch. For a moment he felt one hand pull away, but seconds later it was back at it, this time warm and pleasantly wet. I expected angry acceptance at best in this, but she is trying to make me enjoy it.
The blonde sister pumped away for a few more minutes before Snape finally touched her shoulder, met her eyes, then gently tapped the top of her head. She nodded and rearranged herself on the floor, then swept the silver hair out of her eyes and bent towards his cock again. Severus felt one hand grip the base of it firmly, then he was engulfed in her soft mouth. He felt himself almost explode right then, but caught himself. A few more minutes, at least.
Narcissa was not inexperienced, and within thirty seconds Severus knew this was the best mouth he'd ever fucked. She swirled her tongue around his veiny shaft enthusiastically, pumping her right hand up and down the wet base of his cock and squeezing ever so lightly. For a moment she would suck half of him vigorously, then only the head for a while, her tongue probing at the very tip. Next she would submerge his entire seven inches in her throat with ease, the tightness of it milking his cock rhythmically. He suddenly laughed as he remembered the first lips that had touched him down there. A nervous, giggling third year at Hogwarts who had fumbled with his breeches for five minutes then taken him in her mouth, which felt as dry as sand. He had painted her face with his cum all the same, leaving her to return to class in that state. But Narcissa Malfoy had the skill of a thousand stupid schoolgirls.
She looked up at his laugh quizzically, her mouth still stuffed with cock. "It is nothing," Snape had to stifle his grin. "I was just recalling how terrible every other girl has been at this before you." That seemed to make her face brighten, though her cheeks flushed a rosy red. She went back to her duty, her wet mouth moving up and down faster now, squeezing tighter on him.
Seconds later Snape felt it, and grunted for Narcissa. She gave a "Mmph" in response and sucked him harder than ever, her right hand pistoning around his cock in between gulps. Finally his seed came up, and first shot down her throat. She gave a noise in surprise and withdrew him from her mouth. As if offended, his cock pulsed angrily and shot the next spurt of cum, and the next, and the next. By the end Snape was lying back in his chair almost limply, sighing in content. He looked down to his shrinking cock next to her face, dripping jizz onto the floor below. Narcissa sat there a moment longer, and when he glanced at her he almost laughed again. Her pale silky hair was messy with cum, matching her drenched face and neck. A spurt had landed on her robes as well, in between her robust tits. In youth, just the sight of her like that could have made him hard again. Lucius experiencing that before me is a monstrous crime, Severus thought.
When she had cleaned up and was on her way, she turned back for a moment and Severus caught a smile playing on her lips briefly. He returned it, but by then she had gone, her shapely ass disappearing behind the heavy door. He lay where he had, his cock still out and damp. The girls of Hogwarts have a new standard to uphold, I think.
