Thoughts ravaged Snape's mind. Unclean thoughts; the kind he would rather not have because of the guilt they induced. The image of his hands ripping open Bella's dress and sliding down her small body made him shudder in both pleasure and horror. How could he desire something so carnal, so impure? He tried not to let his mind wander further as Bella's hand slowly tempted his hardness. It was bad enough he couldn't prevent himself from hardening for her. He could not let her know he desired much more.

"I will do anything…" Bella whispered into his ear again, lightly flicking it with her tongue. "Anything."

Snape's breathing was shallow and he tried not to grunt as her hand tightened around him, then finally released him. He cringed at the loss of her warm, tight grip, but felt a surge of relief that she had let him lose. He turned immediately, facing her and glaring. She did not seem affected; she merely moved her fingers to the top of her dress, sliding the fabric down to reveal her bare chest. Snape's eyes traveled across her body instinctively. He hated himself for not being able to tell her to stop. He had authority, did he not? He could command whomever he wanted with his fierce temper and stony personality. Why couldn't he resist her?

She pushed herself up against him, gently pecking at his chin. Her breasts were inches from his fingers, but he kept his hands down. Meanwhile, her hands were again trailing down his front, stopping at his groin. She slowly took him out, and he grasped at the table behind him for support.

"Bella, please…" He said sternly, hoping she would be intimidated enough to stop, to realize what she was doing.

She did not. Instead, a devious smile spread across her lips, the kind he had come to associate with torture and murder. Apparently Bella knew she was torturing him. Slowly, she began to lower herself until she was kneeling before him, her eyes looking hungrily at his erection. Knowing where she was about to go, Snape fought with his feelings of morality and desire. He considered the situation he was in, and made a decision.

"Why are you really doing this?" Snape's voice was cold.

Bella looked up at him, taken from her concentration on torturing his lower body. "What are you talking about?"

"Do you really care that much about Draco?" Snape said, realizing he was only stalling for time, which would test her will and patience. But ff she was going to torture him like this, he would have a little fun with her. "I would have assumed you would be on the Dark Lord's side; you two are close."

That did the trick. Bella's expression grew dark, and she pouted as she thought of a retort. Snape dug the knife in further.

"Or maybe you're only appeasing him some of the time, while you secretly care more for your family."

Bella looked furious. "That's not true! I'll do anything for the Dark Lord! I'm loyal only to him!"

"Is that so?" Snape said slowly. "So it was he who suggested you come here tonight to--seduce me." He said the last words very slowly.

Bella was pouting, but quickly recovered. She raised herself to his level, and smiled sweetly, which looked quite out of place on her. "What makes you think anyone sent me?… Perhaps I'm here because I want to seduce you."

Snape knew this was a lie, but a small part of him wanted to believe her. He wanted to believe someone would want to seduce him, that someone would care for him or be attracted to him. This small part was the one he usually buried, deep inside where no one could see it. He had felt feelings of attraction before, and they were most unpleasant memories. The Lily in his soul was kept hidden in the dark and dank. At any rate, he decided tonight he could afford to buy Bella's ruse, at least this once.

He let her gently kiss him, and even slid his hands up her back as she did so. It had been so long since he had been close to anyone. It soon became apparent to him that he wouldn't have to do much of the work. Bella seemed completely absorbed in what she was doing to him, wanting nothing in return. Her hands rested on his chest as she kissed him, getting more enthusiastic as she did so. Soon her tongue was on his bottom lip, playing with him until he finally parted his lips and took in her kiss.

Her fingers unbuttoned his shirt beneath his robes and her long nails ran down his chest. He leaned against the desk under her pressure as she moved down his body. She was once again kneeling before him, and her hand gently stroked him. Her eyes burned into his and he realized then just how beautiful Bellatrix Lestrange actually was. He no longer cared that she was insane. He no longer cared if she was working for the Dark Lord. He no longer cared if he got in trouble for having her… He could no longer resist.

"Will you help Draco?" She cooed, her lips moving closer to his hardness. Her big eyes stared up at him teasingly as he prepared an answer. "Say you'll do it…" she whispered tantalizingly. "Just promise to help him."

Snape could barely stand the pleasurable torture, his face slack and his hands gripping the desk for support. He knew one word would change everything. Bella's lips touched his shaft, sending tingles through his body. He knew he would end up agreeing to this, but if he did it too soon, Bella might leave him unsatisfied, having gotten her way. Instead, he stayed silent. She took the bait and went a little further, adding her tongue to the playful kisses. He let his eyes close at the pleasure, his long fingers moving from the desk to Bella's curled tangles. His breathing became raspy and he felt overwhelmed. It was too much, too soon. He wanted the roles to be reversed. He wanted to take her, to hold her, to be in her.

Gently he lifted her chin and scooted up on the desk. She watched, knowing what he wanted. Hastily she lifted her skirts, climbing up on the desk and lowering herself onto his lap. He grunted as he filled her, his arms holding her back. Her hands went around his neck as she began to rise and lower herself slowly. Snape watched her, his arms holding her tightly. She knew exactly how to move, exactly what his body wanted. Within minutes his body raged. The pleasure ached through him like a torrid disease. His breath grew ragged and his nails dug into her back. Bella took advantage of his weakened state.

"Say you'll help Draco!" She said exasperatedly. "Promise you'll make an Unbreakable Vow!"

Snape grunted, staring into her desperate eyes. He wondered if she even cared about her own pleasure. It did not seem so; she hadn't moaned once. It was obvious she was only offering herself to get what she wanted. He did not care, though some of him wished he could make her fall over the edge. He wanted to hear her sighing pleasurably, and see her face relax, even smile, as he satisfied her. It was a silly thing to desire, and he tried not to concentrate on it as he felt his own release so near. She slowed her pace suddenly and tightened around him, sending him over the edge. Moaning and squeezing shut his eyes, Snape's voice barely came out as his climax ripped through his body.

"I will!" He groaned as he came, pulling Bella close to him. "I will help Draco!"

Bella smiled again, a spoiled little girl getting her way. "Yes," she hissed happily.

Snape laid back over the desk as he recovered, his chest rising and falling as he caught his breath. She leaned over him, her hands on his chest. She pecked him once on the lips.

"Right then! Let's make the Vow," Bella said, quickly hopping off of him and straightening her skirts.

Snape, surprised and taken aback at her suddenness, took a little longer to rise. He felt heavy and exhausted from the wash of ecstasy, but he managed to stand, tucking himself back into his pants and buttoning up his shirt. Bella was already in her cloak and standing at the door.

"Where are you going?" Snape asked, shaking his dark locks away from his face and attempting to compose himself.

"To my sister of course," Bella said simply. "To make the Unbreakable Vow."

Snape then realized. "She sent you to me."

Bella smiled. "Of course she did! It's her son… I could really care less."

Snape, though mildly surprised, should have known. He had known all along, he was just swayed by carnal desires and out of his better judgment.

"Let's go then!" Bella said. "You promised. If you don't keep it, I can talk to the Dark Lord about you. I'll make up something punishable. He'll believe me. After all, we are close," she winked, and Snape felt momentarily like a fool.

But as he followed an anxious Bellatrix out the door, he couldn't help but smile inside. He had already been assigned to kill Dumbledore long ago, by the man himself. That Narcissa and Bella wanted him to do it too was purely coincidental. Now he would go to make the Unbreakable Vow with the sisters, and eventually carry out the deed as he had planned all along. But he would do so knowing that he had gotten a little something extra. It had not been Snape that had been taken advantage of, it had quite been Bellatrix. This little secret turned the corners of Snape's mouth up into a devious smirk.

As he started down the long hallway after Bella, his dark cloak billowing behind, Severus Snape felt quite satisfied with himself.
