He was going to clobber Andrew just as soon as he figured out where he was and how to get back anywhere near home. Right now, he was freezing.

"Classic. Just my luck." Xander groaned as lightning streaked across the sky, at least it would be shelter but if anything screamed a-haunted by something nasty, b-vampire or demon lair or c-both of the above it was the house that was momentarily illuminated by the flash of light.

Halloween. Stormy, icy, sleety weather, who only knew where, because Xander didn't and he doubted Andrew had a clue yet where his misfired spell had sent Xander. Now lets just add the spooky abandoned probably ghost, vampire or demon infested old mansion.

"Andrew is sooo dead." Xander grumbled and crossed his arms tightly against his chest, he lowered his head and started walking.

~*~*~*~

"I am so kicking that little shit's butt..." the strange voice came. Decidedly American accent which was very out of place in this rather bleak outcropping of rock on the Cornwall coast.

Sirius quickly put out the fire in the fire place and canceled the spells on the room, then melted into his animagus form and scooted for the darkest corner he could find.

~*~*~

"I-" Xander cut himself off. The parlor off the entrance hall was...warm.

So not good. He pulled the stake from his coat pocket and moved slowly toward the hearth. It was dark, not a single ember glowing in the fireplace, but it was still warm. Too warm.

"Anyone here?" Xander called out clutching the stake tighter. At least he wasn't completely weaponless.

His only answer was a resounding boom of thunder.

"I'm so killing Andrew," Xander muttered as he weighed his options and patted down his pockets. At least he'd just arrived at the Council Headquarters and still had his coat on and backpack over his shoulder. He really wasn't sure what Andrew was trying to do-other than scare him.

Really wasn't it like one of the laws of the universe-or at least Scoobydom. Do not send unnecessary magic in the direction of Xander because the Zeppo Factor reared it's head and magic went wonky? His best bet was to call-but his cellphone was in the front seat of the rental car, parked in front of the Council building.

Second best bet was to dig in and wait for Willow to find him.

~*~*~

Sirius crouched further back in the shadows and watched the muggle-dressed man.

The man was crouched in front of the still warm hearth and emptying his pack. Merlin he hoped this wasn't an auror.

"Flashlight, salt," the man muttered to himself. "Oh cool, tootsie pop, didn't realize I had one in here."

Sirius cocked his head sideways as the man pulled the wrapper off the muggle sweet and popped it in his mouth.

The flashlight shined through every corner of the room. Sirius cowered back as the light hit him.

~*~*~

Xander took a step back, that was one damn big dog, and kinda scary looking. Too thin, too scruffy. The dog's eyes were purely terrified. "It's okay boy, I won't hurt you." Xander called out softly after pushing the sucker to the far side of his cheek.

The dog whimpered.

"You want to stay in here with me? Huh?" Xander held his hand out and moved closer to the dog.

~*~*~

Sirius crouched down and watched the man's approach. The young man smelled good. Strong and alive and most of all there. He was plain lonely. Hiding from Aurors was necessary but he was starved for some sort of companionship, the loneliness only adding to the pain of his tattered sanity after years in Azkaban.

"Easy boy,"the young man said around the tootsie pop, as he slipped a bit closer. The canteen he pulled out of his back pack in hand

Sirius yelped as the cold water splashed in his face.

"Sorry, boy, sorry. Just a little holy water. Didn't hurt you none."

Holy water?

~*~*~

"Easy, easy, boy." Xander scooted closer to the dog that was looking at him with an all too human expression that clearly asked "Are you out of your mind?"

~*~*~

"Andrew!" Willow shouted glaring at the hapless young man. "What did you do!"

"It was-just supposed to..." Andrew blinked and swallowed. "It was supposed to just..."

"Just what?" Buffy asked dangerously.

"It was a happy spell that's all"

"A happy spell? What on earth is going on here?" Giles entered the foyer. "I thought I heard screams of Xander?"

"Andrew disappeared him!" Dawn snapped.

"Disappeared?"Giles scowled.

"it was a spell I got from the joke shop in London. Weasley Wizard Wheezes."

"Oh dear," Giles frowned. "And how on earth did you get into Diagon Alley?" Giles took off his glasses and began polishing them. "Weasley. Arthur's twins, I suppose. Bloody hell, I can't begin to imagine how a Wizard spell will react to Xander. Wiccan and Earth magics react badly enough. What was the spell?"

"It was supposed to make him happy!" Andrew cried. "That's all."

"Dear Lord." Giles groaned. He preferred to feign ignorance of his motley young band's butchery of the English language, but he was quite aware of what they meant most of the time after all these years. He was also quite aware of the definition they had added to "happy" in their high school years. Not a definition he was going to mention just now, especially in front of Dawn. Odds were, with Xander's luck and the specification of "happy", the young man was quite possibly in a brothel or some such just now.

"I need to fire call Arthur. The lot of you-go watch It's the Great Pumpkin and do absolutely no spells-I mean it, Willow. Until I know what we're dealing with it could do more harm than good. Andrew, get that spell for me immediately."

~*~*~

Sirius watched as the younger man crept closer. For now he let him. If the man was unpacking things he needed to protect himself he didn't unpack a wand. And he had a Muggle torch. Could the man actually be a Muggle? How had he found the house if that was the case?

Ahhh...Merlin that felt good.

Soo good.

Sirius leaned into the scratching just behind his ears. Merlin that felt good.

"Yeah, that's a good boy," the man murmured. "You gonna keep me company. Huh? You're not flinching from silver anymore than you did from holy water."

Silver? It was then Sirius noticed the cool slickness of metal against his fur. Silver ring. What kind of man was this that "tested" stray animals with holy water and silver? And just how bad did he look these days that the man thought to splash him with silver and holy water?

"You gonna keep me company tonight? Til my friends find me?"

"Yip?" was Sirius' questioning reply.

"Okay, boy you sit. Let me put up a ward cause there's something about this place. All I need is some homicidal ghost taking a liking to me."

~*~*~

Xander set about scavenging some dusty blankets and cushions that had definitely seen better days. The amazing thing was that they were there and even remotely usable.

Not sure which direction was which he pulled the sitting room curtains down off the wall. Sleeping with the windows wide open like that was a bit freaky but any bit of sunlight in the morning would be good-just in case.

Okay where was the salt?

~*~*~

Sirius scooted closer to the hearth and watched in disbelief as the man gathered the firewood and kicked a part a rickety old side table and a couple chairs gathering the broken legs. The legs were set in pairs around the parameter of the area he seemed to be staking out about the hearth.

Salt?

Yeah, that was salt. Sirius noted as he got close enough to sniff and was gently shoo'ed back by the man.

Salt circle? An interesting and crude ward to be sure. Something a Squib might resort to using. Maybe that was how he'd seen the house? He was a Squib?

That was a Muggle blessing, mixed with the Holy Water sprinkled about. "Sorry Willow, guess you aren't getting candles after all" the young man pulled five candles, the pillar type maybe two inches wide and four inches tall out of his back pack and set them about invoking an element for protection with each as he lit.

Sirius had heard of such archaic and odd wardings before. He'd studied them in Auror school. They did little against a wizard or witch but they certainly did better than many spells when it came to vampires, werewolves and the like, things a squib would have little defense against. No more than a muggle at any rate, though a muggle would not be likely to believe in such a thing even as it killed them.

Why would a squib carry a canteen of holy water, a large container of salt and candles in a back pack?

"C'mere boy. Lets get a fire going.'

~*~*~

Xander picked up the too shiny stick.

"WOOF!"

Xander looked from the dog to the stick. He looked more closely at the stick. It didn't have much of a stick feel. In fact it felt almost...alive. Andrew had a stick. His kind of magic was different and he was missed by the 'live in secret' magic communities because of the Hellmouth.

And Andrew's most recent goal that had Willow bonkers was his wanting to learn some turn yourself into an animal type spell. Willow was about ready to turn Andrew into a toad.

Andrew was an annoying pain in the butt and Xander was still going to clobber him, but he thought Willow's annoyance was the different kind of magic that she couldn't use or learn.

"This your stick?"

"WOOF" the dog barked.

"Of course it has to be something weird" Xander groaned. "It's a magic stick ain't it? Abracadabra and all that? Why don't you do us both a favor and turn back into a person please?"

~*~*~

Sirius stared a moment. Reluctantly he reverted to his human form and looked at the younger man warily. "Are you a squib?"

"A what?"

"There were wards on this place, it was unplottable. Muggle repelling spells. You shouldn't have seen the house at all."

The young man shrugged. "Annoying guy who I guess is a friend has one of these sticks. Schools missed him when he was a kid because of where he was. Don't have a clue about what a squib or a muggle is. It's Halloween. I was supposed to be visiting friends in Devon. Just flew in from Africa this afternoon even. Get out of London finally, get to the Council house. Get hit by a spell and out in that crap weather and here. I'm Xander"

"Sirius"

"Huh?"

"My name is Sirius"

"Serious?"

"S-i-r-i-u-s. Like the star."

"Star?" the man frowned then shrugged. "Sure. Star. Sirius. Okay."

Sirius glared.

"Look sorry not making fun. Just not used to hearing a name that unusual but hey, really I should be. I'm from California. I know people who go by Oz, Spike and Angel. A friend who's given name is Buffy for Pete's sake. Why not Sirius?"

Sirius stared a moment.

The lightning flashed outside the now uncovered windows.

"Do you hear that?" the man-Xander he said his name was-frowned.

"Hear what?"

~*~*~

Xander shook his head. Maybe he was imagining things. Magic didn't always have to mean a life or death disaster. Just usually.

Then he heard it again. Faint music and voices. "Please don't tell me this place is haunted."

Sirius shrugged. "I've been here a week. Albus didn't say anything about it being haunted."

"Greaaat. It's Halloween. If there's anything that can attempt to haunt it'll do it tonight."

"May I have my wand?"

"Sure" Xander tossed the wand as he reached for his stake.

~*~*~

Sirius winced as Xander crunched down on his lolly. The music and voices were closer. The small fire suddenly roared to life and the whole room changed. Floors gleaming brightly, furniture looking new and clean, walls covered in brightly flowered wall paper rather than the yellowed and peeling bits and pieces that remained on crumbling plaster only moments before. The only area unaffected was inside the salted circle.

"Yeah, haunted." the American said in a 'of course, how could it not be' sort of tone.

Sirius nodded. He stared as three mostly undressed young women little older than Harry wandered in. Then several more.

Xander stared as well. Startled as the gong like sound of the one-time door bell echoed through the entry hall which now had shiningly clean marble tile, at least that's what it looked like.

"We're in a haunted whorehouse?" Xander gaped as the scene before them played out.

Sirius burst out laughing. "Albus would find it amusing to own a haunted whorehouse."

"Albus sounds like a fruit cake."

Sirius laughed all the harder. "He's been called that."

~*~*~

"Not seeing so much of the funny here."

"Between your wards and my wand we're safe enough" the ragged looking guy, Sirius said. "I don't think Albus would send me anywhere dangerous."

"Suuurrree" Xander said doubtfully. "And that-is"

"A succubus?" Sirius frowned. "I've never heard of a ghost of a succubus."

"Maybe it was vanquished or captured in something in here somehow."
Xander said worriedly. "The ghosts energy let's it out enough..."

"You know much about Dark Creatures?"

"I grew up on a Hellmouth. Yeah." Xander answered distractedly. The air had changed. Even if the ghostly house cleaning and the ghosts themselves hadn't encroached on the circle the scent in the air was changing. The feel of the air. And whoa. Orgy in Victorian clothing was commencing on the various chairs and sofas, a table and even a few thick fur rugs on the floor throughout the rest of the large parlor.

~*~*~

"Arthur, thank you for coming," Giles sighed. "Buffy, they're not Demons."

"That's a slayer?" one of the identical young men behind Arthur gaped.

"Bloody hell, she's little," the other said in an equally amazed tone.

"What did you two make Andrew do to Xander!" Buffy demanded.

"I'm gonna get cranky if we don't get some answers!" Willow piped up.

"Girls!" Giles chided.

"It was a bloody cheering charm. Just given a little extra pep." the twins protested.

"A cheering charm?" Arthur frowned. "A cheering charm is harmless--"

"Unless used on Xander, obviously," Giles sighed.

"Does he have some sort of magical creature blood or perhaps some Sidhe blood?" Arthur frowned.

"He was born to muggles to the best of my knowledge. He gets possessed far to easily to be Fey. Nor do I know of a magical creature that gets possessed as easily as Xander does." Giles said tiredly. "Magic reacts spectacularly wrong about Xander though."

"But a cheering charm?"

"It's Xander," Giles sighed.

~*~*~

Xander groaned and shifted. The air was so thick now. He couldn't describe the scent, or even the taste on the heavy air other than, well, lust. And he was certainly feeling it. Parts of him far more than others and there was no where to look that his eyes weren't filled with sights that weren't helping the increasing tightness of his pants.

~*~*~

"Buggerin' hell" Sirius groaned, eyes locked on a foursome of nude ghosts, the one lass splayed out on the floor with a man fucking her mouth thoroughly while the other lass had her face between the first's legs. The second girl's arse up in the air and a man on his knees behind her pounding into her for all he was worth, ghost or no. Every where twos, and threes and sixes and sevens each pair or group more lascivious than the last and in the center of it all the ghost-like creature which Sirius wasn't quite sure was a succubus, though certainly similar as it-she-fed off the sexual energy.

He looked over at the handsome young man. What did he have to lose? It had been over fifteen years since he'd last touched anyone and the magic, heavy intoxicating scent put off by the succubus-like ghost and the sight of the other ghosts was simply too much. He knew he sounded like an idiot but didn't particularly care. "I-I could give you a hand with that"

"Lame, lame line," Xander snorted. "But gods, yeah, this is killing me."

Sirius cast a quick disrobing spell and transfigured Xander's coat into a mattress.

"Handy," Xander said moving forward like a predator. For a second Sirius thought the American's eyes flashed gold, but all rational thought was gone in an only a heart beat as he was pinned to the matress with the heavy weight of the other man against him. A mouth pressed against his own with bruising force. Merlin, it had been far too long. Strong hands, rough caresses.

"My wand, spell-lube" Sirius gasped out as teeth scored along the side of his neck, undoubtedly leaving a mark that would need to be healed in the morning.

He cast the spell badly but it would do. "MERLIN!" he shouted as a finger entered him, more gently than the crushing kiss a second later. The shout he gave as his prostate was found for the first time in years by another's hand was not so much swallowed as devoured by Xander.

"Now, Merlin NOW DAMN YOU" Sirius broke his mouth away from the younger man's after what seemed endless stroking of that spot by calloused fingers. He lifted his legs up around Xander's waist. The blunt pressure followed by stinging burn as his body tried to remember what was once second nature-how to relax and let his partner in.

"Gonna be rough," Xander rasped out.

Sirius growled and thrust his hips upward taking Xander's length deeper.

"Touch yourself" Xander ordered.

Sirius didn't need to be told twice. Roughly stroking himself in time with the nearly-brutal thrusts.

Neither lasted long. Sirius came first, overwhelmed by the powerfully augmented sensations due to the not-exactly-a-succubus ghost's presence and his years of forced abstinance. Xander came only a moment later.

"Sorry--" Xander managed as he regained his breath.

"Don't been too bloody long, ghosts or no" Sirius smiled running a hand through Xander's sweaty dark hair. "Wouldn't mind a go after a few healing charms and no ghosts."

"That sounds like it has possibilities," Xander smiled.

~*~*~

"You mean to tell me we just have to wait for the spell to wear off and for Xander to make his way back here?" Buffy shouted.

"There's got to be something! I could--" Willow exclaimed.

"Girls, there's nothing we can do that we can be assured won't make things worse. Xander is quite capable of watching out for himself for the night. He'll likely find a phone and ring come morning."

"At least it's Halloween and all the vamps and demons are hiding away for the night" Dawn sighed.
