A/N: This has been sitting on my cloud for good long time, but with the long weekend and a sudden urge to write, I wanted to go ahead and post it. This chapter is mostly unbetaed smut, but if you squint, you can find some character clues to what is to come.
It's still mirrorverse, so specific warnings for really rough dub-con, blood and breath-play, and child-abuse triggers (implied in Spock's recalled memory) as well as some Romulan and Vulcan BDSM kinks.
They were sleeping soundly together in a nude tangle of limbs, when a vague thought flittered across the forefront of his mind. She took hold of that slim thread before it faded and pulled.
...Ambitious and dangerous ideas, -still foggy but the intent was enough to wake her fully.
She sat up abruptly in their shared bed and stared at Spock.
He awoke immediately.
His features were closed, but she sensed his vague disappointment in himself, the loathing of his weak human half for allowing this to slip.
She carefully lay back down on her side facing him and patiently waited for him to meet her eyes and speak. He did so approximately three and half minutes later, after having lay with her in silence, his forehead pressed against her own, his mind resolutely still against her probing proximity.
He opened his eyes and regarded her. "I have cared for you as well any Vulcan would his mate. You are protected and sexually satisfied, -are you not?"
"I am." she agreed.
"The Empire takes from us all. It does not escape me that your only viable choice was to be subject to the whims of those you would despise for your own survival...My own included."
Nyota tensed in his arms.
"I don't despise you." she said, uncertain if she were telling a lie or the truth.
"Do not concern yourself. It is not something you can hide from me any more than I can hide what I must do from you." He blinked and looked away for a moment, thoughtfully adding, "There has not been a time when I did not act but for another's interests...That of father, Vulcan, the Empire, Captain Kirk… Until I- had need of you.."
"...It is weakness." he added in a soft whisper, delicately tracing her lower lip with a trembling finger.
"What I must do would put you at risk were you to have any knowledge of it. So, I offer you the option to sever our bond."
Nyota sat up and glared at him, absolutely stunned by this revelation, angry at him for stupidly considering what she knew he was with that Vulcan single-mindness of his, -and she was more than a little frightened by the prospect of being alone in her consciousness, -with her terrible inescapable memories, again.
She took the option out of his hands.
"You plan to betray the Empire."
"...Yes."
She looked at him as if he were completely new to her.
"You would never do this unless you were certain to have the advantage… What could that possibly be-?"
"-I would not burden you with details that would put you at even greater risk."
Uhura thinned her lips.
"Tell me.I am your mate. Am I not?" she asked softly in his home tongue.
"Ha, Khio'ri. (Yes, Star)" he replied with surprising relish and affection, as he cupped her chin possessively and gazed into her eyes.
Uhura gazed right back with a hint of defiance still evident in her features, even after these many months. Spock's lips quirked. He seemed... pleased by this.
Of course he is. Uhura thought. The very idea of my submission to his will in spite of it, arouses him like nothing else.
"Our own is not the only plane of existence, as I am sure that you are aware. It is a basic accepted hypothesis taught to every Vulcan child during early instruction in theoretical science. You, who are unusually logical, -for a human, should be able to comprehend this."
Nyota nodded in indication that indeed, she did.
"Rips in space-time are theoretically possible, -black holes which can bridge different realities of existence. I believe that a vessel has slipped through one of these openings, -a vessel from one possible future reality of this plane."
Uhura looked gobsmacked.
"Spock. You are a Vulcan. What possible proof have you seen that would convince you of this; -that this foolhardy betrayal is the wisest course? "
He sighed and got up out of the bed, suddenly closed.
"I have shared what I will. You will service me now, komih-itsk t'nash-veh (small human, -belonging to me)."
Uhura stared up at him for a moment, blinking at him. Fine, he could avoid this for now, but she would learn what she needed before his plans could affect her. She would not stand idly by while he doomed them both.
She got on her hands and knees on the bed and crawled the short distance, to his standing form; her face level with his waist.
He threaded his fingers through her chin-length hair with one hand, finger-combing for a moment before abruptly yanking her head back, making her gasp. He bent down slowly and nuzzled her face, -licking her mouth open tenderly, as he took hold of his lok. He then straightened and glared down at her face, his thick engorged length twitching in hand, bare centimeters from her waiting mouth.
"Nash-veh-thinoi (consume me without thought,-wastefully), Nyota."
Nyota licked her lips once, before doing as she was told.
Her fists tightened and released beyond the artificially weighted cuffs binding her wrists, which clinked in-time with his deliberate thrusts, as he grunted and hummed behind her.
He cursed her under his breath, for wrenching such extreme emotion from him, -why must she insist upon knowing that which she knows would bring her more harm for it's possession, annoyingly illogical humans- and so he took her without restraint as punishment.
She tensed, her body coated in perspiration from the effort, but she refused to vocalize for him. She had wanted to know more about his plans. He had refused to tell her. She would refuse him this.
Frustrated and angry, he wrapped both hands around her throat and shoved her bodily upon his lok as he pumped into her from behind, with a cant, depth, and speed only a Vulcan could manage. That elicited a sharp gasp from her and a sneering curl of his lips from him.
When he'd initially bound her in this manner, after he had finished fucking her mouth, he used a tekulik-ponsul on her… a Romulan device, which was routinely used to chastise females into submission through forced orgasms.
The small silver device was no larger than a pill, but when it affixed itself to her clitoris, it stimulated her with a direct intensity that would be painful, were it not for the supple pliability of the object.
He watched her squirm and jerk with calculating black Vulcan eyes, - and greedily took in every small nuanced movement.
She had come so hard she'd sobbed. The force of it left her teetering on the precipice of unconsciousness, while she jerked her hips and shook against her cuffs; slick and dripping between her thighs as the Romulan device continued to stimulate her even through her aftershocks.
Afterwards, Spock palmed her sopping wet cunt, and sliding the hand he used along his length, worked his lok with the slick juices he'd gathered from there. He pushed her thighs further apart, and voraciously lapped at her slit with noisy abandon, while he pleasured himself, enjoying her human taste, and her thoroughly debauched state. The knowledge that he had so capably put her there, pleased him, even more than his own personal stimulation.
He had, as he did candidly admit to her, 'an appreciation for the physical expression of extreme emotion, that only she, as his human, could demonstrate for him'. The reality was that he most enjoyed the attempt; the process of getting her as close as he could to reflecting the heights of extreme emotion that he himself could not fully feel, lest he lose himself, -that fathomless void deep within him that could only be filled by her, more obsession than love, checked by instinct and mental automation. A result of the cruel training of his youth.
Despite this, despite the beatings and torture, despite the humans constantly testing him just to see how Vulcan he was, if he even could be broken -despite it all. He was constantly driven to consume her.
This was her burden.
...And willfully pushing his mate in this manner was his balm.
Presently, he curved one hand around her face and slipped two fingers inside her mouth, while the other tightened painfully around her neck.
She would vocalize for him, even it was in her struggle to breathe. This thought he pressed into her mind as he violently fucked and strangled her.
She gasped and sputtered and coughed around his merciless fingers, and tugged in a panic, futilely against her restraints. When this proved useless, she bit down on his fingers hard.
He shouted and pressed his lok as deeply into her body as he could and came with a shocking intensity, his seed messily spilling from her tender entrance as his lok continued to pulse inside her.
Completely spent, he slipped from her body and collapsed beside her; his gleaming black eyes dancing manically around the ragged teeth marks she'd left his mangled fingers and the shock of a bright emerald smear marring her perfect face.
She was unconscious this time, her body a ruin of her own human sweat and his come...and that vast rolling pit of emotion inside him, sang at the sight.
He leaned forward and laved at her face with his tongue.
Illogical, but necessary.
This was what humans sought in their single-minded pursuit of illogical addictions.
This, -Nyota spent and completely used up; totally in his possession- was his drug of choice.
The cloaked vessel was within communication range of the ISS Enterprise. Nero stood at the helm, his hair the characteristic flatbanged style of Romulans and Vulcans, -his face free of tattoos, his ear intact. He wore simple mining gear as did every Romulan aboard that ship. He, like every other crew-member, practically vibrated in anticipation of meeting the Savior.
They could not wait to stain their weapons with red ISS blood. This was not a warrior's vessel, but every Romulan, much like their Vulcan cousins could not help but be born such.
The plan must be followed strictly, lest it all fall apart.
An electromagnetic pulse, followed by a tractor beam would render the ship indefensible.
Nero would contact the ship, putting on a show for it's compliment of sadists, making sure that under no uncertain terms, they knew that there was no way out but to listen to them.
Men would beam aboard and put the most dangerous members of crew, according to the historical records, into the brig.
...The hardest part would be the woman. Perhaps, they had already changed things simply by virtue of their presence in this universe.
Was it better that he remain ignorant while he removed the hindrance as soon as possible?
This act was known to break Vulcan minds. It was perhaps too risky.
She was the only unknown, in an otherwise virtually foolproof plan.
So, this will likely get a few edits down the road. Sorry, it was so late and more smutty than plotty. This is what Mirrorverse Spock/Uhura do to me. Angst and ISS abuse issues, worked out through kinky sex. Most of the Vulcan words and phrases in this section can be found in the online Vulcan dictionary, but that Romulan device? ...completely made up.
