"Those things will kill you, ya' know?" Xander huffed in annoyance as he watched Spike light up his third smoke of the evening.

Spike took a long drag from the cigarette hanging out of his mouth, eyebrows quirked up at the odd remark coming from the younger man.

"I ain't exactly live and kicking, now am I, pet?" Spike retorted sarcastically, giving his boyfriend a knowing look.

Xander sighed, rubbing the bridge of his nose attempting to rid himself of the on-coming headache he usually got whenever he and Spike argued.

"Those things are disgusting and I can't stand the smell... Not to mention how it clings to everything we own!"

Xander got up from the pull-out and opened the basement window, taking a newspaper to try and wave out the smoke as Spike took another puff on his cigarette.

"You didn't have an issue with it before," Spike said pointedly, taking the cigarette out of his mouth to flick off the ashy tip.

"And that! Stop flicking ash everywhere!" Xander exclaimed glaring darkly at Spike, a look that surprised the vamp.

"Sorry love," he said sheepishly, giving Xander an apologetic look. He ground the ash into the basement floor with his boot in a poor attempt to get rid of it.

"You know what, I'm gonna give you a way to break that habit," Xander announced turning around to face Spike, as a brilliant idea occurred to him.

"Yeah? What's that, then?" Spike looked at him curiously, taking a particularly long drag on the cigarette.

He never knew what to expect when Xander got ideas in his head, especially when they involved Spike.

"Any time you feel the urge to smoke one of those horrible things, I'll suck you off," Xander replied with a smirk.

Spike quirked an eyebrow up at that statement, his eyes darkening with sinful curiosity at his lover.

"That a promise?" Spike's voice a low growl from somewhere deep inside his throat.

Xander felt the heat rising in his cheeks at the way Spike was now looking at him, suddenly at a loss for words as the vampire backed him up against the washer.

He managed to nod his head in response, swallowing the lump at the back of his throat.

Spike took the cigarette from between his lips and flicked it into the nearby sink, turning his full attention back onto Xander.

"Well, go on then..."

Xander reached out and undid the button on Spike's jeans, sliding the zipper down before tugging them off the vampire's hips, letting them fall down around his ankles.

Xander knelt down, taking the soft appendage in his hand and rubbing his thumb over the tip of it as it slowly came to life in his grasp.

He began slowly stroking up and down the length of it, leaning forward slightly to press his lips to the head before opening his mouth.

"That's it, luv..." Spike spoke as he tangled his fingers into Xander's messy hair, holding his head still as he took Spike into his warm mouth.

Sucking and licking every inch of him, his hand firmly squeezing the base as he stroked up to where his mouth was. Spike growled, low and guttural as he urged Xander to take the full length of him.

Xander gagged at first as Spike's dick hit the back of his throat, but quickly recovered and continued on with his mission. He was drooling slightly, but he knew Spike enjoyed it when his blowjobs were messy.

"Bloody hell, pet..."

Xander bobbed his head, sliding up and down the length, moaning around the cock in his mouth.

He felt his own dick begin to stiffen up, straining against his sweatpants and no doubt leaving a wet spot on the front of them.

Spike started to thrust his hips, his cock going further into Xander's mouth everytime he sucked Spike in.

Xander put his hands on Spike's thighs in an attempt to better balance himself, eyes going wide each time Spike forced himself further down his throat.

"Yesss, nearly there love," Spike groaned, feeling that built up pressure in the pit of his stomach. He braced himself on Xander's shoulders, hips bucking a few more times.

Xander soon felt the cold jizz shooting down his throat, swallowing as quickly as possible to avoid choking. Nothing killed the mood faster than spitting up your lover's spunk.

Spike pulled himself from Xander, tugging his jeans back up and doing up the zipper. Xander stood to his feet and leaned against the washer, trying to catch his breath.

"Thanks for that, I don't feel the need to smoke now," Spike said with a smirk, pressing a kiss to Xander's lips and smiling at the taste of himself on his boy's mouth.

"Where the hell do you think you're going?" Xander spoke, voice low and breathy. Spike had started to turn away from him, but Xander caught him by the wrist and pulled him back.

"Oi..." Spike started but was cut off as Xander crushed his lips over Spike's.

"Now it's my turn," Xander whispered against the kiss, hand grasping the back of Spike's head.
