FYI Adult themes ahead.

Spock was under the impression that they were going out to eat but things did not seem to running according to schedule. Nyota stood in front of the bathroom mirror in her underwear attempting to mediate a diplomatic dispute between a brush and her hair. Spock was sitting on the bottom of the bed putting on socks. Shirtless he rose to his feet and approached the bathroom door. He met Nyota's eyes in the mirror and she huffed out a breath.

"I'm sorry, I'm almost ready I swear," she assured him, putting down her brush and turning towards the door.

"So you have previously claimed," he told her not attempting to hide his appraisal of her. She looked at him sternly and squeezed past him into the bedroom.

"You're not exactly dressed either," she said eyeing his chest. Spock raised a brow and remained silent as he turned into the bathroom and began to fill the sink. Nyota pulled on a pair of pants and stood to watch as he splashed water on his face, rubbing a towel across his skin and blinking several times at the cold. As he entered the bedroom he found her staring at him with an odd look.

"Is something troubling you?" he asked as she stared at his chest.

"Hmm?" she answered, shaking her head a little and raising her chin to meet his eyes. "Oh! No, no...just...sometimes I worry myself."

"Explain," he asked, setting down the towel and moving closer. Nyota smiled and hitched a shoulder.

"I don't know what's wrong with me," she explained. "I just...I can't stop looking at you." Spock narrowed his eyes at her slightly.

"And this concerns you for what reason?" he asked. Nyota grinned and dipped her head.

"It can't be healthy. I think the sex has messed up my head," she confessed. Spock nodded in understanding and stepped closer.

"Some kind of brain fever no doubt," he said sagely and she raised her head to give him a mock scowl. "Or perhaps a head trauma."

"No doubt," she drawled.

"Let me examine your cranium," he said, grabbing her and abruptly spinning her around.

"Spock!" she squealed as he ruffled his fingers through the hair she had spent so long attempting to coif neatly.

"There does not appear to be any outward sign of injury," he said matter of factly and she spun around and slapped him on the chest. Spock grabbed her arms, holding them away from him and Nyota screwed her face up as she wrestled against him. Spock peered down at her and raised one eyebrow.

"So illogical," he chided and she narrowed her eyes at him before leaning forward and sinking her teeth playfully into his chest.

"You!" she groused and then grunted, gritting her teeth and jerking hard against his grip in a futile effort to shove him back. She let out a startled gasp as he spun her around, wrapped her in a tight embrace and trapped her arms by her sides.

"Do not attempt to resist," he told her. "There is no escape."

"Oh fearsome Vulcan overlord," Nyota mocked as they stumbled towards the bed. "Have mercy on me."

"There will be no mercy," Spock drawled in her ear and she squealed as he hoisted her up into his arms and deposited her unceremoniously on the mattress. Nyota shrieked with laughter as Spock crawled across her and stuck his tongue in her belly button.

"I'm terrified," Nyota assured him, scrunching her nose up and wriggling beneath him. When he attempted to pin her wrists above her head, she bent her knees up and pressed them against his torso.

"This one has spirit," he observed. "Perhaps we will spare her and make her our concubine."

"Oh my god, seriously?" she gasped, descending into hysterics as he wrapped a strong arm about her legs and her hair fanned out across the sheets behind her as he dragged her down the bed towards him. Spock let out a little growl and placed a mock bite on her calf. He ran his hands down her legs and spread his palms out across the flat of her stomach, circling for a moment before moving his fingers to the fastening on her pants. Nyota dug her hands into the sheets and wriggled her hips as he tugged them down. "So much for dinner," she quipped. Spock narrowed his eyes at her.

"I would not recommend leaving this bed until we have established the nature of your malady," he informed her, pulling her pants over her feet and throwing them on the floor behind him.

"My malady?" she queried with a small sigh, parting her legs as he ran his palms down the inside of her thighs.

"The cause of your libidinousness," he mumbled against her skin. Nyota smacked him on the side of the head. Spock narrowed his eyes at her but she could not miss the twitch at the corners of his mouth.

"I think we know the cause already," she drawled, sticking her finger in his ear. Spock turned and nipped at her hand, kneeling between her legs as he hooked his fingers in the elastic of her underwear. Nyota stroked her hand through his hair and chewed her lip, her stomach twitching as pressed his lips to her hip bone. "Fuck!" she muttered, covering her eyes with her arm as he cupped her centre with one hand and divested her of her underwear with the other.

"In a word," he uttered idly, kneeling and peering down between her legs, his eyes following the path of his fingers as he traced the shape of her sex. Nyota screwed her face up, pouting up at him and her breath hitched with the pleasure of it.

"Sp...Spock," she stammered, trembling beneath his touch and reaching her hand up towards his face.

"So illogical," he murmured, kissing her palm and she whimpered.

"You make me this way," she gasped as he leaned down and pressed his lips to hers. She kissed him hungrily, scraping her nails across his scalp and down the back of his neck. Spock groaned in pleasure and breaking their kiss, rubbed his nose against hers for a second before proceeding to kiss his way down her throat.

"Yes," he mumbled as he left a trail of hot, open mouth kisses against her skin. Nyota whimpered and clutched at his shoulders in desperation.

"You make me crazy," she whined, her face screwing up with need.

"Tell me," he implored, tugging the fabric of her bra aside and taking her nipple between his lips. Nyota groaned and arched her back towards him.

"Sometimes I want you so much I think I might die," she confessed, hiccoughing as her breath caught in her throat. Spock moaned and buried his face in the valley of her breasts. "I think I must be mad," she cried, digging her fingers into his hair hard enough to hurt. Spock gasped and raised his head, staring at her with a deranged expression that sent a bolt of pleasure straight through her.

"Yes," he gasped, pressing into her touch. His eyes screwed up as though he were in pain and he inhaled a ragged, stuttering breath. "It is a madness," he moaned, his lips against her palm. Nyota leaned forward and held his face in a hard grip as she kissed him, taking his lower lip between her teeth. Spock growled and shoved her back onto the mattress so hard the air was forced out of her lungs. Nyota heaved a sharp breath and when he pushed her legs apart and buried his face between them, she cried out as though she were in agony.
