Sorry this one took me longer than usual to write; for some reason it was hard to get it the way I wanted it. Enjoy!
Shepard nodded approvingly to herself as she looked at the rifle sitting on the table in front of her. It was the last of her weapons, all of them properly calibrated as Garrus would say. They would have to be. The Normandy was maybe 12 hours out from the Omega 4 Relay and what the commander assumed would be one of the worst fights of her. Were they ready for it? She liked to think so, but either way, it was time. The Collectors had forced her hand by attacking the ship, and whatever Miranda might have said, Shepard's crew wasn't expendable, not to her anyway.
Behind her, the door chimed, and the commander rose enthusiastically from her chair. She had a suspicion who might be waiting for her, and she wasn't disappointed when she found Subject Zero standing in her entranceway.
"Hey," Shepard told her lover with a naughty little smile, "Wanted to get in one more go for the road, I see."
"Yeah, maybe," Jack replied, the convict surprisingly unenthused by the prospect of sex. "I don't know. Can we talk?"
"Of course." Shepard led the biotic across her cabin, giving her a kiss meant to comfort more than inflame before sitting down next to her on the bed. "What's up?"
"I need you to promise me something," Jack told her, her voice as serious as the commander could remember hearing it. "About tomorrow. The mission, and all."
"Anything."
"Don't let them take me, Shepard."
She nodded, brushing her hand gently over the side of her lover's face. "I won't, don't worry."
"I fucking mean it," Jack practically yelled. "I spent most of my fucking life being caged up like a damn animal. The Tetlin lab, the Purgatory… I'm not going to die that way. You saw those fucking pods the Collectors stick people in. You put a bullet in my goddamn head if you have to, but no matter what, you don't let me end up in there."
The commander swallowed, not quite sure how to respond to a request like that. "Jack, I… It won't come to that. I won't let it."
"You can't fucking promise me that," she snapped, fear and anger mixed into every word she spoke. "I mean, you might be the most badass girl I ever met, but this is some fucked up shit we're going into. I don't need to know we're coming back from it. I know we don't get to be sure about that stuff. I just want you to promise you'll do what I asked. No matter what, you don't fucking let them have me."
Shepard took her lover's hand and squeezed it hard. "I promise, Jack. If the worst happens, we go down fighting. Together."
She felt a little of the tension in Jack's muscles ease. "Good," she told her commander. "I just… you get it, right?"
"I do," Shepard agreed. "There are worse things than dying."
"Fucking true." Jack shook her head as if clearing out the residue of their conversation before leaning over and giving Shepard a kiss far less chaste than the one they had exchanged when she first arrived. "Now," the biotic added, "I think you said something about one more for the road."
"Only if you feel up for it," Shepard assured her. "If you want to just talk or sleep or whatever, that's fine too."
Jack laughed. "Screw talking, girl scout. Look, I know shit's been really fucked up lately, and maybe it's about to get a lot worse, but for tonight, we've got each other. That sound good to you?"
Shepard didn't really get a chance to reply before the third kiss covered her mouth. This one was hotter still, a fierce, insistent thing that left the commander gasping by the time it was done, and when it was, Jack pushed her back down onto the bed. Once the Spectre was laying against the pillows, the biotic moved quickly, yanking off her skimpy top and cargo pants in two swift motions before moving on to Shepard's uniform. Shirt, pants, bra, and boxers departed in rapid succession, leaving the Spectre as naked as her lover. The biotic's tongue moistened her lips in anticipation, and while Shepard struggled to find anything to say, Jack wasted no time in climbing on top of her, grinding herself against the red-head's growing erection while reaching down to fondle her breasts.
"Hey," the commander finally managed to say, "I appreciate the enthusiasm, but there's no rush. We've got all night."
Jack barely seemed to hear her though, instead taking hold of Shepard's shaft and rubbing it over her waiting pussy. The wet folds felt incredible against the commander's hard flesh, and she felt herself tremble with anticipation as Jack guided herself in, taking Shepard all the way to the base in two determined motions. The Spectre groaned at the tightness that was now gripping her, but even as she swallowed hard, trying to stop from exploding too quickly, Jack started moving, fucking herself on her lover's body.
"Fuck, Shepard," the biotic hissed as her girlfriend took hold of her ass to try and get some control over their lovemaking, "Fucking do it."
Shepard complied, thrusting upwards, and as she did, she saw her lover's brown eyes locking onto her own green ones. Jack was always intense when they had sex, but this went beyond that. It was as if her girlfriend was trying to draw every ounce of pleasure she could from what might be their last night together, to find something she could hold onto in the face of the evil they were about to confront.
That was a sentiment the Spectre understood, and she tried her best to do the same, to simply be in that moment, savoring everything it had to offer. The delicious friction of Jack's pussy sliding up and down her shaft, the feel of her hands roughly massaging the Spectre's breasts, the intensity in her gaze; those were what she focused on, letting them take her away all from the darkness ahead of and behind them.
It wasn't long before she felt herself approaching her limit, but when she managed to mumbled out, "So close," Jack hardly seemed to care. If anything, it drove her harder, her motions speeding up, and even while Shepard was filling her lover with shot after shot of her release, the biotic didn't stop. She kept riding the red-head hard, unwilling to let the intensity slacken even for a moment.
Shepard did her best to keep up, her thumb finding the biotic's clit, her other hand pulling Jack as far onto her cock as she could go, her lips devouring her tattooed skin, and soon enough, her lover was crying out her own pleasure, forgetting her earlier worries in a symphony of screams and curses. Her own climax slowed her down no more than Shepard's had, and the commander rapidly found herself losing track of their peaks, one orgasm blending into the next, the two women claiming each other until neither had anything left to give.
Her own pleasure exhausted itself first, her softening cock spilling its final weak pulses inside Jack's sex even as the biotic kept riding her, the commander's thumb and her last thrusts enough to draw one more orgasm out of her lover. It was all Jack could take, though, and when at last, her shudders stopped, she collapsed almost at once, slumping down on top of the commander.
"Jack?", Shepard asked quietly, but there was nothing for it. Jack was fast asleep, and even as the commander felt fatigue starting to overtake her as well, she eased the biotic off of her cock, a mixture of their fluids trickling out of Jack as she was rolled over onto the tangled mess of sheets their lovemaking had created. She looked peaceful for once, fear and rage washed away by bliss, and Shepard smiled at having been able to bring her that comfort.
Shepard settled down next to her, looping her arms around her lover, sated and simply enjoying the feel of their sweaty skin pressed together. Jack's chest rose and fell in the rhythms of sleep and the effect was almost hypnotic, luring the commander to join her. Before she did though, she placed a final kiss on the stubbly hair at the back of Jack's head and whispered a nearly silent promise. "Don't worry, cutie," she told the woman who had helped to save her sanity, "I'll get us through this somehow."
Miranda lay in the small private bed her status as the ship's XO afforded her, staring up at the ceiling with dark, restless eyes. Sleep was proving more elusive than it usually did for the operative, and she suspected she knew the reason why. In spite of all the dangers she had faced in the employ of the Illusive Man, this mission was different. There were simply so many unknowns, and if there was one thing Miranda Lawson didn't much care for, it was unknowns. Cerberus had spent two years planning nearly every detail of this operation, from Shepard's resurrection, to her modifications, to the crew that would accompany them, but the endgame was resistant to such control. No one knew what awaited them beyond the Omega 4 Relay, and there was a very real chance that they would die there, with no one even the wiser as to what they had found.
Of course, if they did pull this off and destroyed the Collectors, she had to be ready for what would come next. She only had a small window before the commander and that ridiculous criminal she'd taken up with found out what had happened in which to act. For now, however, no one else knew the secret she had just discovered. Even Doctor Chakwas, who had administered the key blood test that was part of the crew's final physicals was none the wiser.
Of course, that was because she wasn't looking for the same thing as Miranda, unaware of the little substitution trick the operative had played with Jack's pills. Miranda, by contrast, had been waiting for this, and thanks to a back-door Cerberus had helpfully built into the Normandy's medical record system, she alone now knew that Subject Zero was pregnant.
