A/N: In this story I need you to believe one thing - the adjoining spell is not needed by a pure slayer.

Chapter 1

Buffy suggested to Parker that they just talk. She was interested enough to want to get to know a little more about him. It had been a long time since she'd been interested in talking to any boy that wasn't Angel...or one of her best friends...or Oz...okay, there was Giles too, but anyone else - big with the no interest. 

Buffy, the girl, just wanted to make a connection with someone - anyone. She was so tired of being on the outside in the relationship game. When did it get to be her turn? Buffy, the Slayer, also wanted a connection, but there was no way that this boy was worthy of her. Unfortunately for the Slayer, Buffy, the girl, seemed to be running the show for the moment. But as the tinglies started and moved their way up her spine, the Slayer thought that maybe that was about to change. 

Turning slowly, she saw the source of her inner warning. Oh yeah, the Slayer was definitely coming out to play for this one.

Spike and Harmony stood before her, an unconscious man held up between them.

"Spike," she said flatly before throwing an amused glance at his companion. "And Harmony."

"Buffy. Hi. What a cute outfit... last year," the blond vampiress snorted derisively.

"Well this is interesting. Sort of a double date." Spike lifted an eyebrow, challenging the Slayer.

"Looks like your friend started the party a little early, huh?" Parker joked, oblivious to the tense undercurrent circling the group.

Spike was stunned at the fury that threatened to overwhelm him at the sight of the Slayer and her date. He desperately searched for something to say, to mask his confusion. "So, let's have a look at the new boy."

Holding out his hand, Parker introduced himself. "Hi, I'm Parker."

Spike stared at the hand in fascination, wondering why the need to reach out and swipe the git's head from his shoulders felt stronger than anything he'd ever felt before. He ignored the boy when the proffered hand was removed, turning instead to the woman that the girl he knew had finally become. "He's got...what's the word? Vulnerability."

His words seemed to come to her from a tunnel, and she replied automatically. "And you with Harmony. What'd you do? Lose a bet?"

They both ignored Harmony's indignant 'hey!'

Spike felt the walls closing in on him. "Actually, how we met. It's a funny story," he stated before thrusting the unconscious boy into Harmony then leaping the couch in a mad dash to get away.

Claustrophobic feelings threatened to choke him. He had to get out of the frat house. He had to get away. Now.

With a sharp order, the Slayer demanded Parker stay where he was before following the bleached vampire out into the night.

The Slayer moved at a speed she was unaware she'd been capable of.

Spike struggled to hold off his demon. He'd not had to fight so hard in decades. The beast raged against him. The primal growl that came from behind reverberated through him, allowing his demon to finally gain the upper-hand.

A second growl, domineering in nature, halted his momentum. The vampire whimpered as he stood frozen in place. Spike felt like he was standing outside his body, watching events unfold. His demon mewled in uncertainty as it turned its head to watch as the predator approached.

Luminescent lavender eyes captured gold.

He felt the fear as it coursed through his body. 'So this is what the prey feel,' he mused silently. He felt the power coming off her in waves; it was ancient, overwhelming. Her ethereal beauty shocked him to the core. It was like he was seeing her for the first time. Flashes of energy crackled around her in a visual display, reminiscent of a violent electrical storm; wind that only existed around her form whipped her hair into a frenzy of movement.

As she neared him his need to escape was equalled by his need to stay. Trust her. He was a deer caught in car headlights, his terror on par with his fascination. Her eyes held him in place; her shining lavender eyes; luminescent; effulgent.

The slayer spoke words that had not been heard on this plane in a multitude of millenniums; words that spoke straight to the heart of the beast before her. "I allowed you your relationship with your sire. I forced myself to stay my hand until you learned of her perfidy for yourself. I waited for you to be ready and you dare...dare to flaunt that desecration in front of me," she hissed in fury.

Her hand whipped out to encase his throat and she dragged his limp body upright and towards her, their noses almost touching. "Learn this lesson now. You. Are. Mine!" she snarled as she wrenched his head to the side and struck with the speed of a viper.

Spike felt his body explode in orgasm as her teeth tore into his neck, obliterating all connection with the Aurelian line. His demon howled in exultation as it felt the blood leave his body and the new connection form. His demon purred with the knowledge that it was finally home.

His demon might be jumping over the moon, but Spike was pissed beyond telling and, as his anger blossomed into a fiery rage, he took back control of his body.

What the BLEEDIN' FUCK had the bitch done to him now?!!

Morphing back into his human guise, Spike snarled and tried to push her away from his neck.

She snarled in return before lifting her head and meeting his eyes.

Spike was momentarily startled by the changes in her; glowing lavender eyes and small fangs that dripped with his essence. His traitorous body hardened in response. His cock fought the prison of his jeans.

With her claim in place, the Slayer calmed, curious as to why he still seemed to be fighting her; resisting the destiny fate had gifted him with. Did he not realise that he was hers? Oh well, he would learn.

"What in the bloody hell just happened here, Slayer?" he demanded furiously.

Buffy blinked as her slayer side receded. Opening her eyes wide and lifting a hesitant hand to her face, she stared at the enraged vampire in horror. She could feel his blood coursing through her. She could feel all of him. She mentally groped for an answer, a reason, someone to blame. She acted on instinct as her fist shot out to punch him in the nose. "This is sooo your fault, Spike!"

"MY FAULT?!!" he bellowed in disbelief. This bint was crazier than Dru!

"If you hadn't turned up at that party, none of this would have happened. And you brought Harmony, I might add. I should stake you on principle for that action alone!" she snapped with derision.

"And if you had gone alone rather than with that sleazy little pillock, who has the scent of five other birds on him for your information, you might be in the position to cast stones on my choice of a date. And what the bloody hell have my dating choices got to do with you goin' feral?" he snarled back, resolutely ignoring the fact that she'd claimed him or that the sticky mess in his jeans was becoming a tad uncomfortable.

"Oh! I so did not go feral," she hotly denied, even though she was working hard to hold back on wigging out completely. She had fangs!

Spike lifted a hand and counted off his fingers. "Your eyes changed colour and glowed; you grew fangs; you spoke in a dead demon language; and you BIT me!" he gloated smugly. "That taste in your mouth? That would be my blood, pet!"

"EWWWWW...don't say that!" she squeaked as she slapped him on the chest. 'Not good, not good,' she mentally chanted. Fear dictating her actions, she grabbed the hand of the equally clueless vampire and dragged him with her as she headed in the direction of the only person she knew that might be able to shed some light on the situation. "We're going to see Giles."
