So, this was written for a prompt on the k-meme and as a gift for the awesome Rae D. Magdon. It definitely ends up being the dirtiest thing I have ever written and contains a sort of variant on the "magic cock" that turns up in many of her stories, though more based on weird science than strap-ons. If that's not your thing, I totally get it, so I thought I'd warn everyone upfront. With that said, I hope you enjoy this.

Miranda Lawson was rounding a corner in the Cerberus facility when the attack came. In spite of her training, she was still taken by surprise, a strong hand grabbing the operative and slamming her against the wall before she could react.

"What have you done to me?!" Shepard demanded, her frantic tone revealing the true measure of the powerlessness she felt in that moment despite having her hand at Miranda's throat.

"Why, I think that would be obvious, Commander," the operative replied coolly, seemingly unfazed by her situation. "We brought you back from the dead. At outrageous expense, might I add."

"That's not what I mean and you know it," she snarled.

"Ah, that," Miranda replied, a smug, knowing smile etched onto her lovely face. "As I just told you, Cerberus has made a considerable investment in you, one that we intend to have repaid with interest. You are, after all, the first human Spectre, a warrior of unparalleled skill and cunning, and those are traits that humanity is likely to be in dire need of. Traits that we're interested in you passing on to future generations."

"And you thought this was the best way?" She couldn't believe what she was hearing. Did that mean… Did they actually expect her to… "You're mad!", was the only response that came to mind.

"Well, we can't very well have you getting pregnant in the middle of a mission of this importance, now can we? No, this will allow you to pass on your superior genetic material to as many partners as possible while keeping you fit for active duty. We will then collect any children that might result, and make sure they are raised to be of use to humanity."

"You mean of use to Cerberus?" She'd seen the labs where Cerberus performed its twisted experiments in the past, and she couldn't believe that this Illusive Man would allow anyone else to benefit from his work.

"We are humanity, Commander."

"I won't do it," she protested as her hand slipped away from Miranda's throat, but her voice lacked much conviction. Even in her anger, just standing next the gorgeous Ms. Lawson was having an effect on her. The woman's perfect curves, her full breasts, her taut stomach: all of them were teasing her through the clinging, white cat suit she wore. Shepard could already feel the stirrings of unwanted desire, and she had a horrible feeling that Cerberus was going to do everything in their power break her self-control, something that had never been her strongest trait to begin with.

As Shepard walked away, her shoulders slumped, Miranda's smirk deepened. The former Spectre might have been protesting now, but Ms. Lawson had no doubt that she would surrender in the end to the pleasures Cerberus had to offer. As the head of the Lazarus Project, she had spent considerable time studying the woman's psychological make-up, and while the commander may have been a model of virtue in field, when it came to the bedroom, her appetites were prodigious.

From what Miranda had been able to find out, the only person Shepard had ever been faithful to as an adult was that asari scientist who had helped Cerberus retrieve her body from the Shadow Broker. She was a potential complication to be sure, but also one that Miranda was confident could be dealt with. Liara T'Soni was safely distant on Illium, and even if Shepard made contact, the asari's new-found obsession with the Broker should keep her out of Cerberus' way. And even if it didn't, Miranda had already found the most delicious bait…

Something was wrong with Shepard. Liara knew it in her bones. She may have been inexperienced when it came to romance, but she was also an asari. In the month before Shepard had died, they had made love almost every day, and each time they joined, Liara had seen such love and passion in her partner's mind that she couldn't believe that there wasn't some deeper explanation for what was happening now.

Every time she and Shepard were together, the new Shadow Broker ended up confused and frustrated. When they first reunited on Illium, Liara had tried to brush aside her own lingering doubts and fears, and kissed the Spectre. For an instant, as their lips met and Shepard moaned with desire into her mouth, the asari had been convinced that everything was about to go back to the way it had been before her beloved died.

And then Shepard had pulled away, a confused, ashamed look on her reddened face that Liara had never seen there before. They had had an awkward conversation, a hasty farewell, and then the commander had left, off to save the galaxy again.

A month later, she had come back, this time bearing intelligence on the Shadow Broker. As they battled the Broker's forces, everything had seemed fine. They laughed and bantered and once more, Liara had let herself believe that things were going to be okay. When at last they had defeated the yagh and Shepard took her in her arms and kissed her, it seemed like her fairytale ending had arrived. Instead, her former lover had pulled away once more, leaving Liara with only a vague promise that she'd have her over for a visit at some point and an intense longing.

No, something was definitely wrong and the new Shadow Broker was determined to figure out what it was. Her first thought had been that her lover had met someone else, but with her new-found access to the Broker's intelligence reports on the Normandy, she doubted that was the case. Certainly, some of its crew seemed interested in her commander, but she couldn't find any evidence that Shepard had succumbed to their advances. She was convinced that it has to be something else, and she had to know what. Liara had a hundred other things to do, and a vast intelligence network to get under control, but until she solved this mystery, she wasn't going to be able to focus on them.

"Info-drone." She turned to the small, floating ball of light next to her desk. "Send whatever information you have on the Lazarus Project to my terminal." Maybe the secret lay in the project that brought Shepard back to life.

The files proved to be quite extensive. The Shadow Broker had had an agent named Wilson on the inside of the project and the volume of the material he leaked was proving a little overwhelming to her. She might have been a scientist, but bleeding edge molecular biology was far from her specialty and much of the terminology was hard for her to follow.

Currently, she was watching a video from the later stages of the project. Miranda Lawson along with several other scientists and doctors were standing around the medical crèche containing Shepard's body, discussing the progress in her revival. At first, it seemed to be more of the same techno-babble and she was starting to think she'd need to call in an expert to make sense of it, but then Miranda moved and what Liara saw next almost made her fall out of her chair in shock. For the first time, she had a clear view of her lover's lower body, and there, nestled in a patch of red hair, jutting out of her crotch, was what she could only describe as a penis.

"Just let me know if there's anything else I can do for you commander."

As the doors to the elevator closed behind her, Shepard slumped against the back wall, Kelly's suggestive words still burning in her ears. She was going mad. At least that was how she felt sometimes. It seemed as if the composition of her crew had been selected specifically for the purpose of breaking her will and she was worried it was working.

Miranda in her skin-tight cat suit was bad enough, but with every world the Normandy visited, things kept getting worse. The tattooed biotic, Jack, spent all her time walking around in a garment that would barely qualify as a bra let along a shirt. The thief, Kasumi, was an enticing mystery, coy smiles and slinky curves half-hidden beneath a hood and a tactical cloak. The justicar, Samarra, had the body of the Goddess herself and an air of mystical unapproachability that somehow made her all the more alluring. Even her old friend Tali in her all-covering but surprisingly tight environmental suit was starting to look good to the frustrated Spectre.

The worst, though, was the constant temptation posed by Kelly Chambers. The yeoman never seemed to miss an opportunity to flirt with Shepard. She'd sneak double entendres into every conversation. She'd "accidentally" brush up against Shepard in the halls, letting her delicate hands drift over the commander's aching body. She never missed a chance to offer her help, to tell Shepard about her experiences as a dancer, or to suggest that the commander needed a "therapeutic massage."

All of it had left Shepard feeling like an exposed nerve. The thing that Ceberus had put between her legs seemed to have a mind of it's own. It would swell with desire at the most inopportune moments, straining against the boxers she'd taken to wearing, desperately wanting all the flesh that was constantly on display in front of her.

She knew that was why Kelly was there, her and probably some of the rest of the crew too. Cerberus wanted to make Shepard a prisoner of her own lust so that they could turn her into breeding stock for their purposes. She was trying her best to resist, but it kept getting more and more difficult to hold out. She couldn't even get herself off. She'd tried a few times, locked alone in her cabin, to stroke her straining cock until she got some relief, but it hadn't worked. Every time she touched herself, the disgust with her own body and with what Cerberus wanted from it had left her unable to continue but still ragged with need. More and more, she looked forward to missions, because only the fatigue she felt after combat let her overcome her intense frustration and find a little sleep.

Now, Liara was coming to visit and Shepard didn't know what she was going to do. After Hagalaz, she'd tried putting her former lover off, making excuses as to why this wasn't a good time for Liara to come and visit, but over the last week or so, the Shadow Broker had become remarkably persistent. Shepard had run out of ways to delay and with Liara on a shuttle over to the Normandy, the commander was a nervous wreck.

Every time she was around the beautiful asari, the cravings were incredibly intense, stronger than with anyone else. In the past, her armor had thankfully hid the painful erections that being near Liara caused, but now, she had no such protection. She loved Liara, loved her like no one that she'd ever met, but how could the asari want the freak that she'd become? No, she'd have to maintain her distance tonight and keep things professional. Hopefully, she'd at least get through the evening without embarrassing herself.
