Seven Sins

Lust

'You let me violate you,

You let me desecrate you,

You let me penetrate you,

You let me complicate you...'

They were like a pair of magnets - total opposites and yet, inexplicably attracted to each other.

Every meeting between them ended in either bloodshed or sex...or both, usually with the Joker pressed against a wall in a steamy alleyway, tears of laughter streaming down his face as Batman thrashed and pounded into him. Afterwards the vigilante would leave, disappearing into the night and abandoning his arch enemy to be consumed by the pain and mirth...

Then there were the nights when they were not the Dark Knight and the Clown Prince of Crime...the nights when they were Bruce Wayne and Jack Napier. Bruce didn't know if that was the Joker's real name or just another of his aliases but it didn't matter...when 'Jack' was curled around his body Bruce felt complete.

Dirty.

Used.

Treacherous.

But complete.

"You complete me..." he heard himself murmuring one evening, holding his sleeping lover as though he was an innocent child rather than a mass murdering lunatic. He wiped away the greasepaint gently and brushed a finger across the scars...they didn't frighten him anymore. Jack's eyes flickered open - he was a light sleeper as a rule - and he smiled, his tongue darting out to taste the invading digit.

"I remember sayin' that to you not so long ago..."

Bruce laughed edgily as he recalled the violent scene in the interrogation room, "Yeah...yeah, I-"

"And then you punched me," Jack's hazy brown eyes hardened slightly as he sat up, the covers falling away from his bruised and bony torso. Teasingly, he grinned and ran his fingers slowly through Bruce's thick brown hair, digging his nails into the pink scalp visible beneath, "Maybe I should return the favour."

Bruce turned away in casual defiance, hoping the pleasant shudders running through his body did not betray his eagerness, "Later...I'm a little tired at the moment..."

Jack laughed throatily, reaching over to flip the other man onto his back before pinning him within his wiry arms, "Oh no you don't! Silly little boy...didn't your mother tell you it's best to let sleepin' dogs lie." Bruce chortled and pretended to stuggle, white teeth snapping at the cruel, but exquisite, face hovering just out of reach above his own.

"Yeah, especially if they happen to be rabid!"

Jack scowled and began to playfully pummel his misbehaving bedmate into submission, secretly aroused by the knowledge that, if the mood had taken him, Bruce could have easily stopped him at any time and beat him to a pulp. This train of thought was suddenly interrupted by something hard pressing into his thigh...his favourite toy, ready for playtime...

Bruce smirked maddeningly and began to grind his hips slowly, the delicious friction causing Jack's own cock to twitch and stiffen.

"Look what you've done now, you bad boy..." he growled, his tongue flicking out to taste Bruce's ear, "I don't think you deserve my cock..."

Bruce moaned pitifully and Jack petted him soothingly, pressing his lips against the other man's for a fleeting moment, "Shhh...be a good boy and maybe, just maybe, I'll let you-"

"Master Wayne?"

Without warning, the door creaked open and a beam of light penetrated the darkness that engulfed the naked couple. Bruce leapt up, pushing Jack beneath the covers just in time as a concerned looking Alfred popped his head around the door.

"Sir? Are you alright? I heard strange noises and-"

Bruce mustered a smile as he tried to muffle Jack's protests with a sweaty hand, "Yes Alfred, I'm fine...I just had a nightmare. How was the concert?"

Alfred's eyes narrowed suspiciously but he returned Bruce's smile readily, "Oh, it was quite good actually. I was just a little worried when I came home and couldn't find you. A little early for you to be in bed, isn't it?"

Beneath the sheets, Jack suddenly clamped his teeth around Bruce's restraining fingers, causing the young man to let out a yelp of pain and release his captive.

"Master Bruce? What in the world is wro-"

"Nothing Alfred!" Bruce managed a cheery tone and wrapped his legs around Jack, who was trying to squirm free of the bedclothes, "I've just got a little bit of a headache, that's all....nothing a good night's rest won't fix."

Jack gave a muffled giggle and reached up to wrap his cold hands around Bruce's now flaccid cock, slowly pumping it back to life with cunningly skilled fingers. Bruce shifted and stifled a moan as a wet tongue began to trail a hot, sticky line up his inner thigh.

"Should I bring you some painkillers?"

"N-no...really, I'll be fine."

Alfred's lips tightened, "Well...if you need anything, just call for me."

"I will. Night Alfred."

"Goodnight sir."

The door clicked shut, submerging them once again in shadows. Bruce waited a moment before ripping aside the covers to reveal Jack, whose mouth was now inches away from its destination and whose eyes were blinking up at him innocently.

"What?"

"What the hell were you thinking?!?"

Jack shrugged and began to sprinkle light kisses over Bruce's stomach, "Sorry...I, ah, couldn't resist. Now...lie down..."

"But-"

"Bruce..."

"But I-"

"Bruce...lie down."

Bruce sighed and closed his eyes as Jack began to crawl slowly towards him, smirking in the shadows. Tommorrow, things would be back to normal - or as close to normality as was possible in Gotham City - and he would be running whilst Bruce, his handsome face partially hidden and delicious body encased within that infamous suit, chased him...

And when he caught him...

"You complete me..." Bruce murmured, stirring him from his thoughts. With a lick of his lips, Jack rose up and silenced him with a kiss.

"That's my line."
