Ch.8

"Mac, you're fucking takin too long!" Charlotte whined, staring at her brother as he stripped down. She looked to her left where the alarm clock sat on the nightstand, "you have fifteen minutes before midnight," she reminded. Mac glared at her forgoing removing his jeans and stepped up to the foot of the bed. One dark eyebrow rose in question, he took in her naked form silently, she was-as she'd always been-unabashed about her nudity in front of him. "thirteen," she chimed softly. Immediately his calloused hand shot out, rough fingers wrapping around her thin ankle. With a sharp jerk and a pop of her thigh joint, Charlotte slid down the bed until her legs were tossed over the footboard.

"You're bein impatient, though I taught you better than that?" he commented dryly. Another whine slid from Charlotte's throat, bubbling up and out before she could stop it. Her hand came up, covering her mouth, body tensing as if she expected to be hit. Mac's hands slid up her calves from her ankles and continued the outside of her thighs. "Seems though, since ya gave me a time frame and all, that I ought to give you what ya want, so I can get on to havin a little more time come round two." Charlotte's body relaxed, eyes widening as Mac's hands tightened on her ass, positioning her on the footboard, before dropping to his knees, mouth level with her bared cunt. She didn't have time to think before his tongue invaded her channel. She moaned out, hands coming down to his head, fingers gripping hair, mind unsure whether or not she should pull him back or hold him in place. The wood of the footboard dug into her back harder with each drop of her gyrating hips, a steady pain that kept the haze of impending orgasm clear enough that she could still focus.

"Two minutes," her breathy reminder had Mac's eyes flicking upward, a smile on his glossy lips as he started working double-time. Suckling, biting, kneading, every purposeful motion of his hands and mouth had her on sensory overload. The clock ticked down.

Sixty…fifty…forty

A long lick, short flick on her clit, a kiss, a sharp bite, then he'd change his routine. It was enough to have her whining, pleading with unintelligible words.

Twenty…fifteen…ten

Her back arched, spine crackling and adding to the bliss. Pleasure swept through her in tsunami sized waves, her short yellow nails dug into Mac's scalp urging him on until she burst, her scream was silent as she came. It was so dazing that she hardly noticed her body falling, the only thing between her tailbone and the thick footboard being Mac's hands as he caught her and shoved her back on the bed. Her eyes focused after a moment of silence, her brain playing catch up to the rest of her.

"Don't get comfortable, I held up my end of the bargain," Mac growled, watching her stretch her lithe frame languidly, pleased cat sounds emitting from her parted lips. Charlotte rolled with the stretch, laying on her stomach and turning her head to face her brother.

"So what's next?" the smile on her face was one of pure wicked temptation, something she couldn't possibly have learned by watching Disney movies, but the Cheshire grin of the seductresses occupying good porn mags. Mac smirked back, picking up a beer from the dresser and taking a swig. He climbed onto the bed with her, crawling over her with eyes gleaming, mind planning scenarios to completely tarnish any purity left in the girl under him. The beer hit the nightstand when her long legs curled over his hips. Missionary was outdated, but it would serve as round two and a test to how flexible baby sister really was. Her hands came down, his pants and belt were parted and hanging loose, but her hands pushed them farther until his steely erection was in her palm. She rubbed him a few times, ensuring that he was completely equipped to continue.

Mac groaned, gripping her wrists in one hand and jerking them over her head. The arm he'd braced on the bed bent at the elbow, his lips caught hers searing and dominating. Charlotte moaned grinding her lower body against his. Their bare chests slid against each other, sweaty in the heat of Cainsville evening and over-heated pleasure. She felt like all the little nerve endings in her body were being shocked, sizzling as Mac continued to pet and kiss her. He was more enthusiastic than he'd ever been, smiling lustily at her. Mac pulled up, using both hands to lock around her thighs and pull her core against his cock. The tip prodded, he looked down at her; that was all the warning he gave before driving himself in to the hilt. Charlotte imagined-briefly-that, had Beast not had her first, Mac's roughness would have brought a tremendous amount of pain. Instead, her head was tossed back in a long moan that drifted into a deep purr. Mac seemed to like that noise, falling forward on his hands, hips drawing back so only the tip was still inside and then shoving back in. Another purr, another thrust, Charlotte rocked her hips up with each plunge Mac gave. It was amazing, Mac's hands gripping at flesh, the rough denim of his jeans rubbing against the backs of her thighs and calves. Her nerves were going to be completely shot after these over-sensitizing acts.

Above her, Mac grunted and growled, taking bites out of neck and leaving behind deep teeth marks. His fingers grasped and pulled at her thighs, gaining purchase and leverage. Then, suddenly, she was pulled off her back. Mac sat up, holding her on his lap. Her hands wrapped around his neck, pulling him into a kiss. She held still, looking into eyes identical to hers. They'd never found out how it was possible for their irises to be the same, even the internet failed to provide insight, leaving them to believe it was another sign of their fucked up family.

"Don't just fucking sit there!" Mac snapped, hand coming down on her ass. Charlotte let out a yelp, pushing up on her knees to escape the sting. His hands slid up to her hips, using his hold to guide her back down. A unison groan escaped the siblings; Mac moved her up again, than down, up, down. She was coming down harder, sinking him deeper. Her throat couldn't keep up with the sounds she wanted to make, resorting to silent gasps and lewd hums. Her core started to contract, tightening and she knew that she was close. Leaning forward, Charlotte dropped her lips to Mac's collarbone, sinking her teeth into the space like he'd done to her. She felt his cock jerk inside her, registering that he was reaching his peak as well. Not to be bettered, Mac growled, shoving Charlotte back onto the bed, pulling her legs over his shoulders and doubling his thrusts. She tried to keep up, but his pace was faster, harder, than it had been. The best she could do was hold on, nails digging into the sheets. The finale wasn't bright and blinding like it usually was, she just sort of snapped with a cry of ecstasy. She wasn't given time to bask as Mac kept going until he'd spilled his seed inside her with a groan. They fell into a mass on the sheets, Mac on his back, Charlotte laying half on him and half on the bed. She could feel him inside her, running down her thighs. She liked it, knowing that they'd finally committed the act that she'd been waiting for since…

Since she'd stopped fearing her new family and accepted that she was entirely Mac's.

Mac shifted, grabbing the beer from the night stand, his other hand stroked her hair absently. Charlotte felt like a content cat, stretching her used body against her brother's and drifting into a sated sleep.

They rutted, fucked and made love several more times before the sun came up, taking a few breaks to sleep or eat and drink. Around five a.m. they both passed out, naked, Charlotte wrapped possessively in his arms.
