A/N: Okay, so this is my first ever Mac story, so go easy on me! Depending on what you all think, I could be convinced to expand this into a multi-chapter fic, but as it stands it's a one-shot. R&R :)

An Agreeable Ache

As it turned out, the bitch was light as a fucking feather. She might have looked heavy, stumbling blindly across the canyons in the middle of the night. But holding her against him now, he figured he could carry her one-handed. Mac had watched her from his truck, for a while. She had no goddamn business being all the way out here. No shoes. No water. And the way she had to drag each step out of her bare legs made him think that she was either drugged or drunk or both. That last part made him smirk. She may as well have been wrapped up in a pretty little bow.

Mac flipped on the lights to his truck, and she stared right into them. Didn't even blink- like a deer caught in that empty highway trance. That made him grin even wider. Maybe when he was done with her, he'd string her up and run her down. It'd be a bitch to get out of the grill, but just might be worth it. He pawed roughly at his growing bulge, picturing her all spread out for him, waiting to get rammed by his truck.

While he watched, the girl abruptly re-animated. She glided towards him over the smooth rock, and Mac got a better look at her. She was wearing one of those denim button-up shirts bitches these days seemed to like. White shorts, too. And she was covered in blood, gone all gummy and thick from exposure. It congealed at her shoulders, and dripped down in thick rivers. But as far as Mac could tell, it wasn't coming from her. He might have left her, if it had been. Wasn't any fun to fuck up some damaged whore; he preferred those self-righteous little angels, all shiny hair and wide smiles.

He couldn't tell what color her hair was, under the reddened clay. But even mucked up, it fell in perfect waves past her shoulders. While Mac watched, she stepped right up to the front of his truck, placing her hands on the hood with an expression of awe. She ghosted over the warm metal, followed its curving path with her fingertips.

The girl traced along that slick red paint, all the way over to his door. The way she touched his truck made him throb all the harder in his jeans. Her fingers grazed over it with the same pride and admiration that his did when he was alone, like it was something sacred, valuable. And just like that, he couldn't sit back and watch any longer.

Mac flung open the door, narrowly missing the small-framed girl just behind it.

"Get over here," he growled, expecting her to startle at the very least, more likely make a run for it. But she remained as serene as ever, watching him almost shyly and leaning back against the truck. He looked her over once, licking his lips, then a hand darted out to grasp her by her hair. He spun her around and slammed her into the door, pressing his hips up against her ass so she could feel him.

Still, she remained silent, malleable. Mac's lip curled into something of a snarl; he'd fuck that right out of her.

He lifted her with one arm and dragged her over to the bed of his truck, flipping it open and forcing her against the floor. He ripped her shorts down her body, and grinned lewdly at what he found.

"Commando, huh? Dirty little whore…"

He kicked at her ankles, forcing her legs wider, and ran a calloused hand up the inside of her leg and to her core.

"Fuckin' wet?" Mac rasped, thrusting a finger inside of her. "What the hell you doin' all the way out here wet, little girl?"

She didn't answer, but he could hear that her breathing was picking up. That at least, was a start. Mac jabbed at her clit with his thumb, and her knees buckled with a gasp.

"Yeah, that's right. You want it, don't you? Kinky bitch," Mac groaned, snaking a hand around her middle to keep her standing. She was tight; tighter than anything he'd fucked, that was for sure. And the heat coming off this girl…she felt feverish, and maybe she was, but Mac would gladly contract any fucked up disease she could give him, so long as he got to have a go at that tight little number.

He fucked his fingers into her faster, harder, until she was pulsing around him. He had the idea in the back of his mind to make her want him, make her beg for release, and then deny her. Mac dropped her suddenly, taking a swift step back to undo his fly. The unexpected movement seemed to startle her out of her daze, and the girl looked back at him for the first time, elbows propped on the bed of his truck.

Nothing. Expressionless. Expectant, if anything; but even that would never be enough.

Abruptly, Mac slammed her head forward, hard enough that when he ripped her back up by the scruff of her neck, her own blood dripped down her face in pretty torrents. Diverging, then coming together. She looked at him again, and he growled in frustration. She hadn't even winced, or shown the slightest inclination of fear.

"What the fuck is wrong with you?" he snarled, wrapping a hand around her throat. His fist clenched, and she gasped and choked for air. But she didn't claw at his iron grip, didn't try to shout for him to stop. All at once, he dropped both hands to her hips and bucked forwards, shoving himself inside of her. That would teach her. That'd teach that fucking bitch…

"Yes."

Instead of an anguished scream of violation, it was a moan. Instead of resisting, her walls pulsed around him, drawing him deeper. Mac groaned unwittingly, snapping his hips forward again. He couldn't remember the last time a woman had said that word to him, not like that. And her voice- all breathy and sweet…a shudder flurried up his spine, and he growled in irritation.

"Don't you fuckin' dare come," he warned her, "You don't get to enjoy this. This isn't for you."

Mac pistoned into her, and the sound of their bodies slapping together echoed out into the vacant desert. But even with her hands pinned behind her back and her face shoved into the bed of his truck, Mac's threats didn't seem to register with the girl. She moaned anew, body thrumming and vibrating around him to the point where Mac fleetingly considered pulling out and killing her straight off. Sex had never felt this good before. Even the whores he paid to make out like they were into him couldn't put on this good a show.

It was because she wanted him, Mac realized all at once. She was biting hard at her lower lip, trying her best to obey his demand and stifle her moans. But every time he bottomed out in that tight, wet heat of hers, these little noises would bubble out of her. Those desperate whimpers made him want to slit her throat, here and now. Instead, he fucked her harder.

His hips were slamming into hers hard enough to bruise, nails biting into the skin at her neck as he held her down, but everything about the way her body was writhing underneath him said she wanted more. She looked at him over her shoulder again, lips quirking as she tried to bite back a smile. And it was all fucking wrong.

Fury ballooned in Mac's chest, boiling over in a rush. He pulled out of her and spun her onto her ass, slapping her hard across the face with a grunt.

"Yeah, you like that? You like that, you fuckin' whore!"

Her head cast to the side with the force of it. She pushed her hair out of her eyes and looked up at him, blood trickling down her lip. And there was that look in her eyes again. Cool, contrary, completely unaffected.

Mac's hand balled into a fist and he punched her hard, a sickening crack reverberating when his knuckles collided with her cheek bone. He watched her raise a hand to her face and daintily press her fingers to the spot he'd hit. Not even a flinch.

"What the fuck is wrong with you?" he snarled again, punching her in the stomach this time. "Why don't you feel it? Why don't you fucking fight back?"

Mac raked his hands through his hair painfully, the picture of frustration. And the girl watched him with an odd expression, then slid forward until her legs hung lazily from the truck bed, pulling herself closer by the loops of his belt.

"Why do you want me to?" she asked him. And that question threw him more than anything, mainly because she seemed so damn sincere about it. Like she expected him to have an answer. Like she just wanted to know.

"There's something wrong with you," he accused, avoiding the question. "You're fucked up."

"Mmhmm," she hummed in the vague affirmative, pulling him inches closer. Smiling when he let her. "What's your name?"

"What's it matter?" he countered defiantly.

"Maybe I'll need to know what to scream later," she said softly, in a tone so innocent and unassuming that he throbbed in response.

"Mac," he rasped.

And before he could say anything else, her hand darted out to grasp him, running her fingers over the soft skin with just the right amount of friction.

"Fuck," he grunted. Her palm twisted over the head, and he hissed through his teeth. "Fuck, just like that. You dirty bitch…"

He let her caress him for half a minute more before wrenching her legs apart and sheathing himself inside.

Mac gasped at the pressure, "So fuckin' tight. Been savin' yourself for me, bitch? Been waitin' for my big cock to come fill you up?"

"Yes," she moaned, throwing her head back wantonly. "Yes, Mac."

And Christ, he didn't want to be as close as he was. But if she kept clenching around him, kept saying his fucking name, he didn't know how much longer he could ride this out. The fact that he wanted to extend this probably troubled him most of all. Usually it was a race to get his rocks off, then out the door. But this girl, she was some top-shelf pussy. And he was going to fucking savor it.

"You want to come?"

"Yes," she whimpered, pressing herself closer to him. He nearly shoved her back, not used to being clung onto like this by any of his whores. But the angle was so fucking good, tight enough to make his vision blur. So he let her wrap herself around him, heels digging into his back invitingly.

"Such a slut for it, aren't you? You'd do anything for my cock," he groaned. "You come when I tell you to come, you hear me?"

He pinched her hard nipples through her shirt, nails stinging sharply. She yelped, then moaned.

"Yes," she breathed, eyes locked on him like he was the only thing linking her to the planet, "Mac, please."

And it wasn't the first time a girl had begged him. Please don't kill me. Please let me go. Please stop. But that word out of her dainty little mouth had him threatening to blow. He bucked into her harder, faster.

"If ya wanna come, ya best do it now, bitch," he panted. One of her hands snaked around to his back, fisting his shirt. The other went far too obviously for her clit, and he smacked it away.

"You come from my cock, or you don't come at all. Got it?" he growled.

She nodded quickly, placing that hand on his neck instead, and holding his gaze. And Christ if that didn't make him want to kill her and come inside her at the same damn time. He tried to think back, come up with any time he'd had sex with a girl face-to-face, and he came up blank. No, he always took his women from behind. That way they couldn't watch him while he came, and he didn't have to look at them at all.

But this girl was utterly fixated on him. Pupils blown wide in arousal, instead of fear. He licked his lips, and felt her clench around him in response. And maybe it was something about his eyes that did it, but one more thrust and she exploded around him, moaning high and long, clinging tightly to his body, and looking him right in the eye as she did it.

Her orgasm milked Mac's right out of him, and he came with a growl that turned to a moan, and then a whimper he'd never admit to. "Fuck."

She slumped against his chest with her legs still hooked around his waist, and her face buried in his chest. He let her. And he wasn't in much of a position to push her away, considering he'd just come harder than he could ever recall, and was having a hell of a time catching his breath.

"Fuck," he panted, after several minutes had passed. She was still pressed up against him. Remembering himself, he pushed her away from him abruptly. The girl barely caught herself from falling backwards, and he wondered again what in the hell she was on. She was watching him closely, but clearly fighting to keep her eyes open.

Mac hitched up his fly and threw her shorts back at her, expecting her to dress herself. He paced back and forth around the side of the truck, looking back at her intermittently. She'd closed the trunk and was leaning against it, watching him with that same eerily calm expression.

"What the fuck are you lookin' at?" he snarled, charging back towards her.

Again, not a word.

"You fuckin' answer when I ask you a question, bitch!"

She tilted her head just slightly. "Mac," she murmured, so soft he barely heard her. The word sounded so intimate coming from her lips that he nearly punched her again, to expunge the memory of it.

"I should fuckin' leave you here!" he shouted in her face, hoping for a response he could work with. But she just continued to look at him, something like curiosity playing at her features. She squinted, as if she were trying to decipher a language she didn't quite understand.

"Do you want me to leave you here?" he finally huffed defeatedly.

She appeared to think about that one for a moment, carefully eyeing the surrounding canyons.

"No," she finally whispered.

He shook his head, trying to clear it. "You're fuckin' nuts, ain't you? Just straight up bat-shit," he grumbled, knowing he wouldn't get an answer.

Abruptly, he slammed his hands down on either side of her body, caging her close to him. It achieved little more than a sharp intake of breath, and even that seemed to be more out of surprise than fright.

"Maybe I'll keep you, huh?" he rasped, face inches from hers. He scanned her face for any indication of her feelings on the matter. "Maybe I'll just fuckin' keep you."

The way she held his gaze made his skin crawl.

Mac pushed himself away from her roughly, holding his hands out in an open invitation and giving her free reign.

"So what'll it be, huh crazy?"

She cocked an eyebrow at him incredulously, then slowly walked to the passenger side of the truck, and slipped lazily into the seat.

Mac huffed out a sigh.

"What the fucking fuck," he muttered under his breath. He slid into the truck beside her.
