Service Unit

Chapter Twenty – Useful

Buffy stepped back into the hallway and stopped. Spike was dressed and standing in the bedroom doorway, looking like he was trying to gather enough courage to step out of the room. She beckoned him with her right hand. "It's okay, Spike. Come on out."

He looked at her, his mouth set in a grim line of determination, then he hesitantly stepped across the threshold and into the hallway. He took a few halting steps, pausing for a few seconds at the guest bedroom door, then continued walking and stopped in front of her. She smiled at him then turned and started walking, saying over her shoulder. "Let's go sit in the living room. I need to tell you something."

He followed her into the living room and watched her sit on the couch, then he knelt on the floor in front of her and sat back on his feet, placing his hands on his thighs. This would probably be the only chance he'd get to prove himself useful… to help her relieve some of the stress that was pouring off her in waves… if only she'd order him to service her, which he was certain she'd never do.

He'd never had to work to get his renters to want to use him, considering that they'd paid for the privilege and intended to get their money's worth and more, but Buffy was different. First and foremost, she wasn't a demon that considered the enslavement of other demons as natural. She was a human with human sensibilities and morals that told her slavery was wrong. Plus, she'd already stated several times that she wasn't going to treat him like the slave he was, so if he had any hope of fulfilling his purpose, any hope of convincing her to keep him, then he'd have to do whatever he could to encourage her to the line of thinking that he was hers to use.

Two thoughts suddenly stormed to the forefront of his mind. One – that he was too filthy and disgusting to be touched by her at all, and two – that he should just let her toss him out before he infected her with that filth. He gritted his teeth and battled the thoughts back, employing that sharp stick from before. She'd touched him already! Dozens of times! Every part of his body! And if she thought he was filthy and disgusting then she wouldn't have done that, would she? He jabbed his pointy stick at the thoughts one more time then turned his back on them, hopefully leaving them to wither and die in the dark recesses of his mind.

He internally shook himself and tried to get his focus back. His objective right now was to encourage his owner to want to use him… Right. But how to do that?

Inspiration struck and he sifted quickly through his memories until he found the ones he was looking for. Spike had always been able to get Buffy in the mood even when she'd been denying she was even attracted to him, so maybe he could employ Spike's methods to get her to want to use her slave as he was meant to be used.

Checking with his memories again, he molded his features into a sultry expression then trailed his gaze up her body, starting at her feet then moving up over her knees, pausing at the junction of her thighs while he let his tongue slip out to lick at his lip. He curled his tongue behind his teeth as his eyes slid slowly over the mounds of her breasts then across her throat. When his heated gaze met hers, her lips were parted slightly and she was breathing quickly. Now it was time for the clincher. He tilted his head then lightly bit his bottom lip and was rewarded with the sudden scent of her arousal. He felt himself harden in response and was elated when Buffy slid forward to the edge of the cushion and reached out, grasping the front of his shirt in her small fists and pulling him fully up onto his knees. His abdomen twinged sharply in pain at the movement, but he ignored it. His plan had worked!

Her lips crashed down onto his in a desperate kiss as she worked to get him out of the t-shirt he'd so recently put on. When she had to move back to pull the shirt over his head, she froze, her eyes wide with shock and guilt. She dropped the shirt to the floor like it was burning her hand and slid backwards. "Oh God, Spike, I'm sorry. I'm so sorry."

He shook his head then pointedly looked at her crotch and licked his lips, amazed at how bold and forward he was being. Uposs was practically gibbering at the audacity of it all… service units DID NOT , under any circumstances, try to manipulate the actions of their owners. He told Uposs to shut it and tried to explain that if he was to stay here… to be kept instead of being tossed out with the rubbish… then he had to adapt to this owner's needs. And this owner needed to be encouraged to use her slave. Plus, he reminded himself as he straightened his metaphorical spine and shot Uposs a two-finger salute, Spike was nothing if not bold and forward, so if he wanted to 'be like Spike' then he had to do the things Spike would do.

XXXX

Buffy sat down on the couch and was about to point to the cushion next to her and ask Spike to sit with her when he sank gracefully to his knees on the floor then sat back on his feet. She'd sort of known that was coming, but what he did next completely stunned her. He hadn't looked at her with anything but fear, confusion, or misery since the hood had dissolved, but now… Damn! Was it getting warm in here?

She felt the familiar warmth and tingle starting up in her lady parts as Spike's tongue slipped out and licked at his top lip. He'd always been the only one that could get her motor revving with just a look, even when she'd been sure it was completely out of gas. Somehow, and she'd never been able to figure out why, the look he was giving her right now had always flipped all her switches over to 'horny now– must have Spike,' and had always resulted in whatever clothing he'd been wearing being torn from his body.

And then he curled his tongue behind his teeth in that way that made her toes curl in response and she could feel the weight of his gaze as it traveled over her breasts and up to her face. When his eyes met hers, she felt like she'd just touched a live wire. A bolt of electricity shot through her, straight to her core, and then… ohhhh… there it was… the head tilt accompanied by the lip biting that had always made her want to jump on him and ride him all the way home, no matter how tired or sore or covered in Doublemeat Palace grease she'd been.

She slid forward and fisted her hands in his shirt, pulling him up to his knees. The only thought in her suddenly horny cavewoman brain was, "Spike lips… Lips of Spike," and then she had them, and they were all soft and supple and yummy. She wanted his skin, too, wanted to feel its silky smoothness under her hands, but there was all this annoying cloth in the way. She started to wrestle him out of his shirt… why had she wanted him to wear it again? She couldn't remember… oh… okay… have to stop kissing him long enough to get it over his head.

She pulled the shirt over his head, and when his face came into view again, the realization of what she was doing hit her like a bucket of ice water. She dropped the shirt and backed away in horror, her hand covering her mouth, her eyes wide with shock at her own behavior. What had she been thinking? Grabbing at him and pawing at him and stripping his clothes off without even asking him if that's what he wanted! She was no better than that creepy little demon in the other room – simply mauling Spike as if she were his owner… as if he were property. "Oh God, Spike, I'm sorry. I'm so sorry."

He shook his head at her then dropped his eyes. She followed his gaze to… oh God… down there… where she was still all tingly. She dragged her eyes back up to his face just in time to see him lick his lips… and yeah, it was definitely getting freaking hot in here.

He raised his eyes to hers and licked his lips again. She felt herself blush and glanced down, eyes widening in surprise at the bulge that was tenting his sweats. She quickly brought her eyes back up to his. He couldn't really want… could he? She was in her rattiest sweats, for Pete's sake! Her face was probably still all splotchy from crying earlier, her hair was a mess, and she wasn't even wearing makeup! The only thing she had going for her was the fact that she'd brushed her teeth before she'd gone in to feed him. But then again, Spike had never really cared what she'd been wearing or what she'd looked like. He'd wanted her any way he could get her… and anytime he could get her.

She glanced down again and felt her cheeks heat even more. He was definitely aroused… and it wasn't the trained response thing like in the shower because she hadn't even touched him… there. A light bulb went on over her head and she dragged her eyes up to his once more. It was her blood. He'd had a wet dream on half Slayer blood, so of course straight Slayer blood was going to affect him even more.

So… would it be okay for her to… do this? Do… him? Her body was screaming at her that there needed to be a lot more action and a lot less clothing and she should just get on with it already. She had Spike right there in front of her, giving her all the signals that clearly broadcasted his raring-to-go status. But if she did, then wouldn't she be raping him just like all those demons because Slayer blood was kind of like Viagra for vampires? Did that make her blood a date-rape drug? Gah! It was too hard to think when he was still looking at her like that! And when his chest and arms were there with all his ripply muscles, and when he was licking his lips… again… 'How about you just ask him, moron. He's not stupid and he can answer questions.'

Right. Ask him. She could do that. She had to clear her throat a couple of times before she could get any sound to come out of her mouth, but she finally managed to ask, "You mean… you want to… um… you… want me?" He nodded as she wondered why she suddenly felt like a teenager again, too embarrassed to articulate the actual words… to say, 'penis' or 'vagina' or 'have sex.' She was an adult woman who'd had penises in her vagina… and other places… and she'd had lots of sex. Lots and lots… most of it with the man kneeling in front of her sporting a very large, very hard penis – and, she had to admit, the whole kneeling thing was kind of pushing a few of her kink buttons… so why couldn't she just say it? 'Oh, for fuck's sake, Buffy. You've had his penis in your mouth! And up your ass! So just grow up already and quit being such a baby!'

She cleared her throat again and asked, "Are you sure? You want to have sex?" He nodded vigorously and she bit her lip. "I don't know, Spike… I mean… after everything… how can you? You've been… well… You don't have to, you know. You aren't a slave anymore. You know that, right? You can choose… you can say no."

Spike nodded then shook his head then nodded enthusiastically again and Buffy took that to mean that yes, he knew he wasn't a slave, that no, he didn't want to say no, and another confirmation that he did, in fact, want to have sex. "Are you sure that this is what you want? Totally and completely sure?"

XXXX

He was losing her. He hurriedly flipped through his memories then stuck out his bottom lip and dipped his head, looking at her through his lashes. She was staring hard at him now, and he saw it when she decided to take what he was offering. Her eyes glazed over with lust and she slid forward again, pressing her breasts against his chest and her thighs against his hips as her arms slid up over his shoulders to wrap around his neck.

XXXX

Oh God… not the pout. She was defenseless against that… the lip… the eyes… she couldn't take it. And Spike knew that, so did that mean… Had he come back? Was he here? All the looks, the ones Spike knew how to use to get her horny when sex was the absolute last thing on her mind… he'd used every single one. She sat and stared at him, trying to figure out what to do.

He said that he knew he wasn't a slave, but was he lying? Was he seducing her because he was still thinking like a sex slave and was trying to get her to use him? Did sex slaves do that? Or was he trying to show her that he was back? That he was Spike? He hadn't done anything up to this point that was even remotely Spike-like, except for the tiny head tilt yesterday, but now… he was pouring on the Spike in bucketfuls.

He obviously wanted this… if the tent pole in his pants was any indication… and it had taken quite a lot of bravery and backbone to let her know that, whichever side of him was currently running the show – the slave or Spike – and she suddenly decided that she was going to reward him for that bravery.

He'd been used and abused for so long and now she had the chance to make him feel good for once. To maybe help him get a little of himself back, like he'd helped her after she'd dug her way out of her own grave. And sex had always been what they were best at, so… if sex was what he wanted, then sex was what he would get. She let the remembered looks rev her engine up to nearly red-line and then she scooted forward, ready to rock his world.

Ohhhh… she'd forgotten just how good a kisser he was as she slid one hand between them and started squeezing and stroking him through all the damn cloth that was still in the way. She pulled back to breathe a little… oxygen is important, after all… her hand still rubbing him through his sweats, and his eyes moved down, feeling like they were scorching every bit of her that they passed over. And when they stopped on her crotch and he licked his lips, she knew what he wanted to do now… it had been one of his favorite ways to spend an afternoon and he'd never seemed to tire of it.

XXXX

She kissed him deeply for several minutes, thoroughly exploring his mouth, and he almost forgot the plan when she started to squeeze and stroke his erection… almost forgot that she was the one meant to be serviced, not him. When she pulled back to take a few heaving breaths, he looked down her body, again licking his lips when his eyes landed on the spot where that delectable aroma was emanating from.

She smiled up at him and asked, "You want to… taste?" He lifted his eyes and nodded forcefully, letting just the tip of his tongue show between his lips as he sat back down on his feet. She immediately stood up and started to shimmy out of her sweat pants and thong, kicking them off to the side. He leaned forward as soon as the way was clear and slid his cool tongue into her moist folds then flicked it quickly across her engorged nub. She squeaked and her hands landed on his head, her fingertips pressing into his scalp as she ground down against his mouth.

XXXX

Buffy had forgotten just how wickedly talented Spike's tongue was – strong yet supple – as it sent bolts of fire shooting through her veins, scorching her with bliss. She rocked her hips furiously as he skillfully worked her with tongue, teeth, and lips, and her cries of pleasure were getting steadily louder the closer she got to orgasm, nearer to falling off the edge of rapture.

"God, Spike! Yes… yes… so good! Spike… yesssssss! Yesssssss! God, yes!"

XXXX

When Buffy finally climaxed, his nose was stimulating her pulsing nub and his tongue was buried deep inside her as she bathed it in her delicious juices. He lapped up every drop he could find as she twitched and gasped and bucked against his eager mouth. Her hot, salty cream flowing over his tongue and down his throat only served to harden his cock even more and her breathless praise warmed him with her pleasure, making her slave feel useful and functional for the first time since he'd stepped out of his shipping crate.

Her twitching and bucking finally slowed and her hands released his head as she stepped back and sat heavily on the couch, panting harshly.

XXXX

Buffy flopped back against the cushion and looked at Spike through half-lidded eyes as she smiled a sated smile, her chest still heaving slightly with exertion. "God, Spike. Wow. I mean… wow." Her eyes trailed down his bare chest and landed on the large bulge in his pants – that looked even larger than before, if that was possible. She sat up slightly and hooked her fingers in his waistband, tugging him closer to the couch. He shuffled forward on his knees and when her hand closed on the bulge and started stroking and squeezing him through the soft fabric, his eyes closed and his face became suffused with bliss.

XXXX

She stopped stroking and squeezing and he opened his eyes to see her smiling at him as she said, "Your turn."

He watched as she fumbled with the knot in the string then slid the sweats down over his hips. His cock caught on the waistband then sprang free, bobbing excitedly as she pushed the sweats all the way down to his knees. She looked up at him as she bent forward slightly and said, "Remember, you can say 'no' anytime. It's your choice. I won't do anything you don't want me to do, so… do you want me to?"

She wanted to use her mouth on him… which was her right as his owner, of course, but… if she brought him to orgasm that way then their proper roles would be reversed again. It was his job to give her pleasure, not the other way around… not to mention that it would take time for him to be ready to service her again, and while he was good with his mouth, he was better with his cock. She had asked him, though, instead of commanding him… and she'd stopped touching him in the shower when he'd told her it hurt… so if he said no, then she shouldn't be upset with him, right? Right. So he'd say no to the blow-job and try to get her to let him use his cock where it would bring her the most pleasure.

He shook his head then made the pouty face as he cycled his gaze between his cock and the glistening juncture of her thighs. She nodded then leaned back and opened her legs wider. "Okay. You want to just get to the main event, then? Are you totally sure?"

He nodded and she scooted her bottom toward the edge of the cushion then grasped him and guided him toward her opening. His eyes closed again as he slowly pushed forward, sliding his length into her grasping heat. She was so warm… and so tight. It felt wonderful, her walls slick against him, and he couldn't help the pleasurable shiver that traveled down his spine at finally being where he fit. There were no oddly shaped protrusions tearing at or bruising his tender flesh, no strange demon secretions burning it, and her sex didn't bend his cock in ways it wasn't meant to bend.

He fit perfectly here, her walls closing on his erection like she had been built to his specifications, pulling him deeper as her supple channel stretched to take him in then molded around his hardness like a silken glove. He hadn't felt this much pleasure from the simple act of penetration since… well, since the last time he'd been inside Buffy, and he struggled to hold back the release that was poised and ready. He quickly brought up memories of some of his worst punishments and they cooled his ardor considerably… enough that he'd be able to perform his job properly as long as he kept those memories toward the forefront of his mind.

He pushed forward the last little bit, seating himself fully against Buffy's womb, then he opened his eyes and looked down at her. She was staring at him, her face suffused with pleasure, and he pulled back then slid forward with a hard thrust, angling his pelvis so his pubic bone would contact her swollen nub. Her eyes closing and her mouth opening to form a perfect 'O' told him that he had the proper position, so he started up a steady rhythm… pull out, making sure to drag the blunt head of his cock across her g-spot, then slam in hard, stimulating her clit.

The repetitive motion was playing merry hell with whatever was injured in his abdomen, but his purpose was to perform his job no matter how much pain he was in, so he tried to ignore it. And the pain was helping him to ward off his own pleasure, so it was serving a purpose, he supposed.

After twenty or so thrusts, his memories threw up a suggestion and he started twisting his hips on the down stroke, dragging his pubic bone across her clit instead of just slamming into it. That made him hurt even worse, and made the pain harder to ignore, but if the moans and tossing of her head were any indication, she was enjoying it, so he kept at it.

"Oh, God!" Her hands flew to the backs of her knees and she pulled her legs up and opened them wide. "More, Spike, harder! Please! So good! You feel so good! I missed you… God, Spike, I missed you so much! Please! More!"

He leaned forward just a little, adjusting his thrusts to the new angle of her pelvis, then started pistoning his hips furiously, still performing the little twist at the end. His abdomen felt like there was a red hot poker stuck in it now… and he knew firsthand what that felt like… something must be really wrong in there, but it didn't matter. He had to keep going, had to show her that he could be what she needed, that he wasn't rubbish. She grunted every time he slammed into her and her breathing was ragged when she let go of one leg and reached toward him, grabbing at his elbow.

He'd put his hands behind his back in their usual position without even realizing it, but now she was tugging on his arm, trying to tell him something in breathy little grunts in between his thrusts into her, "Spike… hands… lift… my… butt."

He brought his hands forward at her order and slid them under her backside then raised her up a little, gripping her flesh tightly as he hooked his thumbs over her hipbones. That gave him better leverage and he bent to the task, leaning forward a little more as he hammered into her. The red hot poker in his abdomen was poking through his back now… and yes, he also knew what it felt like to have a poker rammed all the way through his body… and his thrusts stuttered a little as several searing bolts of agony shot through him. He gritted his teeth and pressed on through the pain. She was close, he could tell.

Only a dozen or so strokes later, her channel tightened on him like a vise and she screamed out her release, her body convulsing wildly beneath him. He slowed his movements, but still drove deeply into her as he tried to draw out her orgasm as long as he could, keep her flying through the clouds of euphoria.

Finally, her body utterly spent, her convulsing reduced to haphazard electrical pulses and twitches of her muscles, Buffy's eyes fluttered open and met his. He recognized the dazed expression in her green orbs… he'd seen it many times before. Relief rose up inside him as he watched her lids fall closed again and felt her body relax completely as she passed out, sated and exhausted. He'd done it. He'd completed his objective. He'd shown her just how useful he could be.

He pulled out of her slowly then lowered her backside gently to the couch and grasped her legs long enough to set her feet back on the floor. He looked over Buffy's debauched form, taking in her obscenely spread legs, her swollen and glistening sex, and the deeply satisfied smile gracing her face, then he smirked at Uposs. Let's see her shower head do that. She'll definitely want to keep me now.

His hands moved to the small of his back again and he sat back on his feet, his hard and leaking cock smearing Buffy's juices on his skin as it bobbed against his abdomen, which was throbbing in agony. He took deep breaths to try to manage the pain as he waited for her to wake up so he could continue his service.
