The day Mac got his truck back was the day he started acting like his old self again. He was on his best behavior in front of Walter though, who'd been dropping in from time to time to check on things. He still did what he was told but with a smart remark or an ass grab thrown in before doing so.

Kristy let them slide. Truthfully the version of Mac she'd seen the past few days was a bit depressing. She'd been worried she had really broken him until the first insult slipped past his lips. She could handle this. A balance between the wild animal she'd first met and the loyal dog she'd beaten him into.

Unfortunately packaging and making small batches of the regular crank left him with a lot of spare time. Cooking with Mac hovering around proved to be taxing. With him there it was no longer an enjoyable act. She had to constantly look over her shoulder to make sure he wasn't watching. She'd debated on asking Walter for her own cave so she would accomplish much more a lot faster. But she feared his solution would be to just kill the fucker.

She looked back to see Mac leaning over her shoulder again for the millionth time that day. Using all her weight she slammed the shoulder closest to him into his chest, knocking him back several steps.

"Fuckin' bitch!" he snapped, grabbing the collar of her suit to yank Kristy backwards, sending her slamming into the ground.

Rocks painfully dug into shoulder muscles that were already strained from constantly having to make sure he wasn't peeking.

"Ignorant tweak." she growled through her mask as she swung her leg out, catching Mac behind his knees.

He went down hard. She took the opportunity to climb on his back and land several satisfying punches to the back of his head.

"Didn't I teach you a lesson last time?" she yelled through the mask's ventilation before he bucked her off.

Walter walked into the chamber to find Kristy and Mac rolling around on the floor. Each attempting to land blows to the other while fighting to stay on top. He had to hand it to her, that girl was a wily one. Even succeeding a couple times in pinning Mac and landing a solid hit to his ribs.

"Suficiente, detener!" Walter yelled, causing Kristy to stop mid punch while straddling his son. "What the hell is going on here? She is supposed to be working!"

She snuck in one more jab to Mac's side before scrambling off him to stand in front of Walter.

"He started it!" she grumbled after pulling off her gas mask.

"Hovering around me like a god damn gnat. I can't do this Walter, I need my own space. He's insufferable!" she ranted, the frustrated words slipping out before she'd thought about what the repercussions for Mac might be.

Walter just shrugged at her. "You wanted him, you got him. You know what to do if you want your own space."

Mac rose up off the ground and quickly pushed in front of her. He really had no defense. He was ordered to guard and package. Not watch.

"Lien' lil cunt!" he spat at her, moving in to attack again.

She saw it coming, delivering the heel of her palm up into Mac's nose with a sickening crunch.

"Maybe now you'll give that damn thing a rest." she sneered, referring to his constant snorting of the product after hours. "Makes you sloppy and uncoordinated in a fight too." she continued, lecturing Mac who was cradling his bleeding nose.

"I'm gonna kill that bitch, I swear ta fuckin' god!" Mac yelled at Walter while looking absolutely murderous, his tantrum muffled behind his hands.

He hated her. Maybe even more than Devon now that she was his father's new favorite and technically his supervisor. He leaned his head back trying to stop the blood flow.

"Oh stop being such a baby." she scoffed in exasperation. "It's not even broken."

It was broken. She just felt like emasculating him further. With a devilish gleam in her eye she grabbed Mac's face in her hands and used her thumbs to reset it. Making him let out an embarrassing yelp.

Walter cackled as Mac pushed Kristy away and prodded at it gently. "Best watch yer back ya stupid whore."

Kristy looked at him in irritated disbelief.

"Excuse me?" she asked sassily as she tilted her head and set her hands on her cocked hips.

"I graduated high school thank you very much, with straight A's at that. I doubt you even understand half the big words I use. And I am not the one giving it up whoring all over town." she countered with a pointed look down at his dick.

"Only cuz one look at yer fucked up face'll make any guy's dick go soft." Mac sneered in retaliation.

"Mackenzie!" Walter cut in, believing his son had gone too far.

Mac glared daggers at his father for using his full name in front of her.

They obviously didn't know her. You cant break what's already shattered. She laughed loudly. 'Mackenzie? Oh, I'm going to have a field day with this one!' She narrowed her eyes, going in for the kill.

"Mackenzie as in the girl's name? As in Miss Manwhore Mackenzie?" She asked vindictively, a triumphant smirk cracking across her face when Mac started to move as to grip her up by the front of her suit.

"Thas enough!" commanded Walter, roughly grabbing Mac by the back of his coveralls.

"No more today, you did excellante." he praised Kristy while simultaneously shoving Mac towards the cave's exit.

"Well thank you Walter, glad to hear it." Kristy replied with an air of superiority directed towards Mac.

"Both of you, go home" he ordered, dismissing them.

She was more than ready to go back to the cottage and get away from the filthy man glowering at her from the chamber's entrance.

By the time she stripped her suit and made her way out of the tunnel Mac's red beater was nowhere in sight. Thank god. Kristy climbed into the Denali, wincing as her muscles screamed out in protest.

While driving home an idea came to her. Why not take advantage of the one admirable geological quality Utah had to offer. Hot springs. She'd read about them online when booking the cottage and they were supposed to be quite useful in relaxing sore knotted muscles.

Making a u-turn she headed towards mystic springs. The mineral deposits from the water slowly over time built up beautiful rock formations, creating a cascade of water to large tubs. The old clawfoots were set apart from each other for privacy and comfortable enough for one soaker. Not Bothering to go back for a swimsuit she took advantage of the nudity optional rule. Fuck it, why not. She was the only one there.

Before dropping her clothing at the side she placed her cigarettes on a natural shelf formation along with a fifth of Jim Beam she was happy to find in the back of the SUV. She slipped into the tub water, hissing a bit at the hot sting. Once fully submerged she lit up a smoke, unscrewed the cap, and took a long pull straight from the bottle. Enjoying the burn spreading through her chest and stomach.

Setting it back on the shelf she let her neck rest on the lip of the tub, letting the water work its magic. Kristy moaned appreciatively at her knots unwinding themselves.

Suddenly a shadow fell across her, blocking out the setting sun. Before she could open her eyes to find the source a large fist connected squarely with her jaw.

"Thas fer breakin' ma nose bitch."

She moaned again for a very different reason. The taste of blood filled her mouth as she held it in her hand unoccupied by the cigarette. 'This is not happening!'

"Go away." she groaned, cracking open one eye.

She observed Mac leaning over her tub to grab her bottle of whiskey before taking a large swig.

"Why does god hate me?" she asked herself aloud while she worked her jaw back and fourth. Not broken. She won.

"Aint no god ta hate ya." Mac replied as though he were the devil himself.

He snatched Kristy's cigarette right out of her hand, taking a puff and smirking down at her. Revealing his rotten mouth to her. 'He is the devil.'

"Ah-men. Give me my shit back!" she demanded as he finished off her smoke and took another gulp of her liquor.

"Come an get it." he teased, waving the bottle at her and taking several steps back while leering down at naked form.

"I'm not in the fucking mood for games Mac." Kristy huffed, standing slowly from the tub, unabashed.

Her nipples hardened instantly from the hastily dropping temperature as the sun set.

Mac was surprised. He didn't think she had the stones to uncurl herself from the water and step out in front of him. But boy was he glad she did. The only time he'd ever seen her fully naked he was too busy saving her life. And ever since that first night he saw her in the Luna Mesa he had wanted to know what other scars her body held.

It didn't disappoint. She was absolutely mangled. He loved it. What he said earlier about her face wasn't just an attempt to hurt her, it was his guilt and shame showing through at how hard her scars got his dick. Mac was straining against the material of his coveralls just looking at them. Water droplets catching on the raised ridges and indented gouges as they made their way down her body. His fingers twitched to trace the ones he hadn't already the day he had her trussed up in the cave. Make more.

While Mac was distracted Kristy wrestled the bottle from his grasp. After wiping her hand over the rim she took several hefty swigs. All the while keeping her eyes on him. Watching him watch her. He wasn't even looking at the good bits. She wrinkled her brow as she watch him trace patterns over her body with his eyes. 'The scars.'

Giving him her lacerated back she made her way to the tub and submerged. After returning the bottle to the shelf she extracted another cig from her pack. She lit it while pointedly ignoring Mac's presence, returning her head to its previous position before his assault.

"Mind if I join ya Krystal." Mac rasped, already unzipping his coveralls and shucking them to the ground.

"Kristy!" she corrected him. "And yes I fucking mind! Go away!" she repeated, opening her eyes at the sound of material falling.

Scabs and sores dotted his body. Disgusting as they were she couldn't deny the muscle definition beneath them. 'Oh fuck, and there go the shorts.'

She'd seen the outline of his hardening cock through the fabric of his jumpsuit. Felt it pressed against her a handful of times. But naked and unrestrained it looked much larger. She started to wonder. Imagine. 'I bet I'd actually feel it if he fucked me.' she thought 'No chance of gentleness there.'

'Ew. No. No junkies.' she reprimanded her wanton imagination.

As he lifted his leg to get in she splashed him right where it counts. Hoping the near scalding water would get him to back off.

"There are two other tubs, go get your own!" she demanded with agitation as he settled in comfortably.

"Other two tubs aint got pussy an booze." he replied matter-of-factly, eyeing her tits with a putrid grin.

Now unsubmerged in her effort to scooch as far to her end of the tub as possible. A useless effort as he brought his outstretched legs to rest on either side of her ass.

She took a drag and exhaled her smoke into his face.

"You're not getting laid." she informed him before starting to stand.

"I cant imagine what loathsome diseases I'm catching just being in this water let alone letting you stick that thing in me." she sneered with a falsified look of revulsion on her face.

She would never live it down if he knew just how wet she got when she thought about him fucking her like an animal.

Mac's hands shot out grabbing her wrists before she could make it out. He yanked her forward, forcing her to straddle him and drop her cigarette, her knees smacking painfully on the porcelain bottom of the tub.

"I aint askin' fer permission." he growled in her ear before thrusting upward, his dick slamming against her clit, sending electric shock waves of pain and pleasure through her.

He repeated the action again and again as her wiggling causing him to almost slip inside once.

"M' gonna pop that cherry whether ya like it 'er not." his gravely voice rumbled in her ear before taking her earlobe between his blackened teeth, biting down.

She panicked, a rare response for her. After that her efforts to get loose doubled, feeding his sick desire for a struggle.

While she fought to free her wrists he moved to lick her scars, causing a gasp to slip past her lips. Taking the opening he slammed his mouth to hers violently, thrusting his tongue inside to explore the gashes from the inside.

Stealing her first kiss and claiming it as his own.

Kristy stopped moving for a moment, sent into shock by the wet muscle invading her mouth along with the pungent taste. His saliva tasted horrible but it felt good. His tongue snaking in and out, mimicking what he planned on doing to her down south. Her struggles continued when the head of his cock nudged her entrance again. Had she not shifted her hips to the side just in time Mac would have been sheathed deep inside her.

She knew there was only one way to get out of this. Well, two. But she wasn't quite ready to give into that yet. Kristy moaned into his mouth and stopped struggling to get her wrists free. Instead pushing his vice-like hands to let her tangle her fingers in the back of his hair.

She sent her tongue into his decaying orifice to mimic his earlier movements. She'd never before been so thankful to be a quick learner.

"Knew yew'd like it." He murmured, pulling away to grin cockily at her.

She ground herself against Mac's dick and smashed his mouth back to hers. Her charade of wanting more dangerously close to the truth. When she experimentally sucked his bottom lip into her mouth his hands finally released her wrists. Moving to cup her ass instead. As soon as she felt him using them to maneuver her onto his pulsing cock she grabbed the near empty whiskey bottle and smashed it over his head.

Mac fell back limp against the tub, knocked out cold. Sitting back on her heels she observed her handiwork. He looked almost angelic like that, features slack, blood running down his face. His head was bleeding but not so profusely that she was scared he would die of blood loss. Most of it was currently located in the head he thought with most often.

Something seemed to be missing, like the icing on a cake. Kristy leaned forward and grasped his chin, wrenching his head to the side. With a vicious smile she sank her teeth into his neck until her mouth filled with blood. Spitting the mouth full in his face when she was satisfied.

'When will he learn not to fuck with me? I'm smarter, faster, and when it comes down to it a whole hell of a lot meaner.' She thought while getting dressed, waiting until he started coming around.

Mac groaned and lulled his head from side to side on the tub's lip. His head ached worse than any comedown he'd ever experienced. And it felt like he'd been stabbed in the neck. Fuck Walter. He was going to rape that fucking whore within an inch of her life and then squeeze the last inch out of her with his bare hands. Smug laughter made him dare to peel his eyes open, his vision was hazy but he could just make out her outline against the almost set sun.

"Well good morning sleeping beauty, did you have a nice nap?" she laughed mockingly as she bent over, picking up his filthy clothes and work boots.

"M' gon fulk yew up." Mac slurred as his vision slowly began to clear.

"Yeah sure and then Walter will kill you. I hope you finally learned your lesson tonight Mackenzie. Don't fuck with me." she advised, raising his clothes into his line of vision for him to see.

"Just to prove my point I'm going to leave you stranded out here naked. It'll give you some time to reflect on what you've done." She declared, leaving him struggling and stumbling to get out of the tub.

Kristy walked backwards while laughing at him the entire way as she kept just out of his reach. She even circled around him once and smacked his naked ass, getting away just as he lunged for her. Nearing the parking lot she abandoned her teasing and bolted for her car when he started to regain his coordination and began sprinting. Letting him just reach her car before putting it in reverse she gunned it out of the parking lot.

Mimicking the first time she'd seen him she stuck her arm out her window, flipping him off with his truck keys dangling off her middle finger.
