Summary: for orchid_slayer who wanted Spilliam with cock ring, the rest was up to me. 
Spike finds someone in his bed and decides to indulge.
 
* * * * *
 
Spike rolled over and his arm flopped over a lump in the bed.  He didn't remember picking anyone up at the bar but the obvious flesh under his hands suggested that he must have.  Exploring further he ran his hand down across some very scratchy fabric to reach a very obvious penis.  Opening his eyes he looked right into a pair of very startled blue eyes.
 
The body belonging to the eyes jerked away from his touch and fell off the side of the bed dragging the sheet with it.  Leaning over the side of the bed Spike looked at a disconcertingly familiar face.
 
"What do you think you are doing?" the body demanded scrabbling back against the wall clutching the sheet protectively in front of him.
 
"'S my bed, that should be my question, William," Spike said hazarding a guess.
 
"Are we related you seem very familiar?" William asked.
 
"You could say that," Spike replied reaching for his cigarettes.
 
William's eyes narrowed and flashed golden, "is this one of Angelus' games?"
 
"No idea mate," Spike said letting his own eyes flash, "woke up and you were in my bed."
 
William looked around the room wildly, "where are the others?"
 
"About a hundred years away by my reckoning, how old are you?"
 
"That is none of your business," William replied angrily.
 
"Yeah it is, if you want to get back anytime soon," Spike said.
 
"Is that a threat?" William stood up and glared at Spike.
 
"'S a fact.  Look you aren't stupid so listen up.  Somehow you have been sent into the future and you are stuck with me until we sort out why," Spike said getting off the bed and going nose to nose with William, "look closely at me," he ordered.
 
William stared at Spike and brought one hand up to touch Spike's face curiously.  "It's not possible," William said, "you look like me."
 
"I am you." Spike pulled back suddenly uncomfortable with William's scrutiny.
 
"That is impossible," William said.
 
"Fuck," Spike swore, "fine then want me to tell you how you turned your mother, how you wanted her to be healthy and live forever?  Want me to say how much the sight of Angelus' in his underwear gets you hot and horny?"
 
"Shut up," William's eyes narrowed, "you don't know what you are talking about."
 
"Or about how you fantasise about killing a slayer and the look of pride and pleasure on Angelus' face when you do it?"
 
"Shut up." William forgot about being in his undergarments and threw himself angrily at Spike.
 
Anticipating this Spike stepped to one side and sent William sprawling.  He picked up his angry doppelganger and slammed William against the wall.
 
"I've got a hundred years on you so cut it out," Spike said with a snarl even as he knew that William would not listen.
 
William attempted to head butt Spike but instead made contact with Spike's shoulder.
 
"Bloody hell," they both cursed.  Spike blocked William's next strikes just as easily.  He remembered his early fighting style and was able to counter it and get in a few strikes but he was loath to hit himself too hard.  But he knew he was a stubborn bastard, and it was doing his head in thinking about himself that way so he pinned William and bit into his throat.
 
William stilled as soon as Spike's fangs sank into him.  Spike didn't drain him completely, only wanting obedience.  He could feel William's hard cock pressing against his thigh and realised that hadn't changed either.  Pulling his fangs free Spike tilted his own neck and offered it to William.
 
Without hesitating William fastened down drinking greedily.  When the blood hit his tongue William's eyes opened wide. There was no denying the blood.
 
William pushed Spike away in shock and collapsed onto the bed.  "How is this possible?"
 
"On a hellmouth," Spike answered, "anything's possible."  He looked down at his younger self with curiosity.  The drawers were hideous and the body inside was much softer than his and obviously well fed in comparison to his own sparse frame.
 
William was looking at Spike with as much curiosity.  Once he accepted the fact that it was him standing there he was fascinated by his elder self.  Whipcord thin with hideously white hair it was still him but not.  It was strange to look at what he had become.
 
"Why are we here in this place?" William looked around the crypt with distaste.
 
"'S my home mate so don't knock it."
 
"We live here?" William said in disbelief.
 
"Not we, just me." Spike said shortly.
 
"Where are the others?"
 
"Things have changed mate.  Angelus is in L bloody A and Darla and Dru are who knows where by now."
 
"Things have changed." William considered Spike's body critically, "you are far too thin are pickings too sparse?"
 
"Stupid bloody chip means I can't feed, I'm working on a way to get rid of it."
 
"Chip?" William looked confused.
 
"Magic," Spike lied as the easier option than explaining technology to his younger self.
 
"I don't trust magic," William said.
 
"Never did, never will," Spike agreed looking at himself thoughtfully as ideas started to form.  "Gonna have to keep you under wraps for a bit.  Wouldn't do for the slayer to find you and dust you and me by default.  Although the fact that you are here and I have still got the chip might suggest that you are not past me but an alternate me, or that you go back before anything changes... at least according to Bill and Ted and Back to the Future..."
 
"What?" William was confused by Spike's words.  "A slayer?" one thing did sink in.
 
"Keep your paws to yourself," Spike said with a growl, "you are not ready for this slayer, not by a long shot."
 
"I could take some chit of a girl," William said.
 
"Your first slayer is nearly going to finish you, so don't get all cocky with me," Spike said.
 
"First slayer?" William perked up.
 
"Only if we figure a way of getting you back.  Have to nick some of the Watcher's books and see what I can find."   His stomach growled, "and find enough money for blood for two..." Spike stopped as he remembered that William did not have the chip, William could feed as much as he wanted.
 
God it was almost too much to think of.  Someone to hunt for him, someone who would understand the crippling frustration of being unable to feed and being alone.  But he knew himself too well and it would not be as easy as asking.
 
William shifted uncomfortably under the intense gaze of his elder doppelganger.  What could possibly have happened to have brought him so low?  Admittedly the thin frame was still strong and handsome to look at, but it did not seem right.
 
"You have to stay here while I go out," Spike said to William.
 
"Why?"
 
"Cause the slayer would sniff you out and create merry hell."
 
"What if I get hungry?"
 
"Tough."  Spike swung a punch that knocked William out cold.  "Sorry mate but I know myself too well."  He dragged William onto the bed and used the conveniently placed handcuffs to secure his twin.  He had to stop his hands from exploring the exposed flesh.  He didn't have time to play before the sun rose if he wanted to get to the Watcher's shop and sneak some books.  He could take advantage on his return, and what a strange idea that was and incredibly arousing at the same time.
 
 
William found he was secured to the bed when he came round.  His own self had punched him and restrained him.  He knew he should be offended, but damn himself for doing the one thing guaranteed to make it impossible to be angry.  It was making his head ache to think of the other as himself even if it was him.  Or not if he understood the earlier ramblings and he wasn't sure he had.  So thinking about him as Spike was probably going to make it easier.
 
Spike had to know how much he liked being restrained, and how embarrassed he got when that desire was exposed.  He could feel his cock twitching against the fabric of his drawers and tried to will the erection away before his other self returned.
 
 
Spike could smell the arousal as soon he returned to the crypt.  It was a weird feeling to know exactly what was going on in someone else's mind, but he knew that William was equal parts pissed at him and turned on by the predicament.
 
"Let me out of these things," William demanded when Spike came down the ladder.
 
Spike dropped his supplies on the floor sending silent thanks to the watcher for having not removed the day's take from the till.  He climbed onto the bed and straddled William's hips.
 
"Now why would I want to do that?" Spike grinned.
 
"Release me this instant," William said.
 
"No." Spike ground his erection into William's enjoying the involuntary moan that escaped the familiar but not mouth.  "Can do anything I want and know that it is what you want too."
 
William's next protest was swallowed up by Spike's mouth.
 
Kissing William was interesting and a turn on.  Dru had taught him but he was still young and inexperience and had not kissed a man before.  It didn't take long until William was responding to the kiss just as Spike knew he would.
 
Spike took the capitulation as his cue to get better acquainted with William's body.  So much like his own but with subtle differences that the years had added to his body.  Spike trailed his lips down William's jaw and neck finding the hot spots he knew were there.
 
It felt incredibly bad to be playing with William, like a combination of masturbation and incest.  He didn't know if he had been as aroused in his entire existence.
 
William was arching up to give him better access to whatever flesh he wanted to reach.  Spike swirled his tongue around the tiny nub on William's chest before biting down on it pulling a curse from William.
 
Spike grinned and turned his attention to the other nipple until it was as hard and red as the other.
 
William's drawers were wet with pre-cum outlining the erect cock straining against them.  Spike removed any ability William had to be able to speak by sucking the head of his cock through his drawers.
 
The taste was as familiar and different as William's blood was to Spike and he knew he couldn't wait any longer.  He ripped the linen off William's waist not caring that they tore, it was going to be a long time before Spike let his other self free of the bed in any case.
 
As much as Spike did enjoy being tied up himself, the combination of being in both roles was so bloody hot he didn't know what he wanted to do first.
 
Remembering his doppelganger was still a virgin in such matters despite his secret desires Spike decided to turn his other self inside out first.  Pushing the unresisting legs apart further Spike nuzzled at the cum heavy balls before running his tongue along the small dark opening. 
 
William bucked with shock when Spike's tongue penetrated him.  Then he lost all sense when one cool hand wrapped around his cock.
 
Spike knew he had William when his younger version started to hump into his hand and push back against his tongue.
 
Spike quickly snapped on the cock ring he had bought and paused to admire the view. 
 
William froze at the strange sensation around his shaft and balls.  When he managed to bring his eyes back into focus he saw his cock was held erect by a ring of metal and two smaller rings encased his balls.  Spike's returned attention to his arsehole distracted him from wondering what they were for however.
 
Finally sure that William was going to completely enjoy what he was about to do, Spike knelt up and pressed two fingers inside the slackened ring.
 
"Bloody hell." William's eyes flew open again at the intrusion.  Drusilla had played around there before but never with such obvious intent.  Spike's fingers moved around until the found a spot on William's internal wall that sent the younger vampire bucking.
 
William had no idea what Spike was doing to him, his dick was throbbing with arousal and, just like when Dru pinched the base, the ring around his cock stopped him from even considering release.  He tugged at his restraints, desperate to break free especially when Spike added a third finger creating a burn just the right side of painful.
 
Spike watched as William began to fuck himself on Spike's fingers, his oh so familiar cock almost purple with need.  Although the cock ring stopped William from cumming, it didn't stop the flow of pre-cum that poured out of the slit making Spike's mouth water.
 
William was a mass of sensations now, every part of his body was humming with pleasure and he was ready to say and do anything to be allowed to climax.  He was accustomed to being denied release by Dru until she received her own, but Spike was doing things to his body that nobody had ever done and it was driving him insane.
 
Spike had one more thing he wanted to do before he sank his cock into his doppelganger.  Abandoning William's now begging hole Spike moved up to straddle William's face.
 
"You want me to fuck you William?" Spike asked the dazed younger him, "do you want to feel our cock inside your arse?"
 
"Hell," William breathed in shock.
 
"Then suck it for me." Spike placed his cock against William's lips, "pretend it's Angelus," he said to sweeten the offer.
 
William opened his mouth to protest the suggestion and Spike pushed the head of his cock inside gagging William's reply.
 
Tentatively William tasted Spike's pre-cum.  Just like the taste of Spike's blood it zinged on his tongue and he eagerly lapped it up.
 
"Suck it," Spike said as the tentative touches drove him wild.  William took more of Spike's shaft into his mouth and sucked it obediently.  Spike looked down at the sight of himself sucking his own cock and nearly blew his load.
 
Spike pinched the base of his cock hard and thrust deep into William's mouth until the vampire started to struggle.  Spike slipped his cock out and draped his body over William so he could taste himself on William's lips.
 
Spike stopped to clean the pre-cum off William's belly admiring how painfully erect William's cock was.  Pushing William's legs further apart Spike slicked up his cock and positioned it at William's entrance.
 
Some clarity came back to William's mind as he felt the thick blunt head press inside him.  "Fuck," he swore looking into blue eyes he could no longer see in his mirror.  It hurt more and felt better than anything since the night his dark princess gave him eternity.  Filling him, claiming him with pain and pleasure.
 
Spike listened to the litany of curses spilling out of the soft pouting lips.  All the years of travelling and exposure to Angelus had gifted him with a colourful vocabulary and William was putting it to good use.  Not that Spike was arguing and would have been happy to add several of his own if he wasn't concentrating on the mind blowing sensations of sinking balls deep in his doppelganger's arse.
 
Spike started to thrust long and fast into William and the song of curses changed into a chorus of panting and groaning.  He knew he wasn't going to last long so he reached over and grabbed the cock bouncing so close to him.
 
"Wanna cum?  Tell me how good this feels," he told his young twin.
 
William was past all rational thought, all he wanted was release and he was ready to do and say anything to get it, "course it bloody feels good.  You're fucking me, I'm fucking myself, just let me cum dammit."
 
Spike grinned at his oh so typical way of begging and took pity on himself.  He unsnapped the cock ring and released William's pulsing cock.  A few well placed strokes and William coated his fingers in sticky cum.
 
The rippling of orgasm around his cock bounced Spike over the edge as well and he pounded his release deep inside William.
 
Before William knew what was happening Spike had swallowed his softening cock sucking it clean and back to hardness.  He howled with frustration when Spike replaced the cock ring around his erection.
 
"Kinda like myself all tied up like that," Spike grinned as he slipped free of William's arse, "know I have to send you back but I figure why waste the opportunity?"
 
"Why indeed?" William smirked willingly taking Spike's cock into his mouth this time.
 
Spike moaned with pleasure and his mind spun with the possibilities of having his un-chipped self around for a while.  Blood from the source for a start, not to mention the fantastic sex.  Yeah, it was going to be a lot of fun.
