After leaving the navigation deck, Shepard took a few minutes to pull herself together. Ashley was an excellent soldier, usually good at following orders, and arguing with her was a rare occurrence. Since they'd started serving together, their only real arguments had been about Liara. Ashley hadn't trusted her because of her parentage, and to a lesser extent her species, but Shepard had decided to keep Liara on board the Normandy anyway. It was ironic that they were fighting over her yet again, although this time for a very different reason.

Their shouting match up on the navigation deck had done little to dissolve the tension between them. All bets were off when an omega was in heat, and Liara's pull was stronger than anything Shepard had ever felt. It was only natural that she and the next dominant alpha on the ship would be in contention for Liara's favor.

Once Ashley stalked off, Shepard stalled for a few minutes, checking in with Joker to give herself a chance to calm down. She needed time to get herself under control before going to find Liara. She owed the omega an apology for being so possessive when it wasn't really her right. Even if Liara didn't pick her, it was her job as Commander to see that everyone respected Liara's choices, including herself.

When she finally reached the medbay doors, a strange smell assaulted her senses. At first, she worried that something was wrong. Liara's scent was overpowering, but there was something different about it, something that Shepard couldn't quite put her finger on. She hurried through the medbay, barely registering that Doctor Chakwas wasn't there in her usual spot, and into the back room.

The doors hissed open, and the sight before her sent her staggering backwards. Ashley was stretched out on top of Liara. A very naked, very eager Liara. Her mind struggled to process the picture, but her body didn't hesitate. Her biotics flared instinctively, their power rippling through her like a blazing fire. It would take so little effort to reach out with them and throw Ashley into a wall, perhaps even hard enough to cause permanent damage. Along with the anger, she felt a sickening clench in her gut, something almost like betrayal. She had no claim to Liara, but that didn't stop her heart from breaking.

What finally spurred her into action was the haunted look of regret in Liara's eyes. There was pain beneath the desire, with a heavy dose of longing mixed in. Shepard couldn't help herself. If Liara wasn't satisfied with this coupling, she wouldn't let it happen. She lunged across the room, pulling Ashley off Liara and forcing her to stand. Relief washed through her when she saw that Ashley's pants were still closed. If they had already started mating - or worse still, formed a knot - there wouldn't have been any way to tear them apart. It took a second glance for her to notice the large patch of wetness against the front of Ashley's fatigues, and she couldn't help feeling the slightest twitch of humor beneath her rage.

Ashley's dazed expression finally cleared as Shepard shoved her toward the door. She seemed to realize where she was, and a look of surprise and fear snapped into place as she processed what she had almost done. "Skipper, I..." Shepard crowded into her space, snarling in warning, and she backed through the door without offering any further challenge. Shepard closed and locked it, ensuring there would be no other interruptions.

At last, she turned back to Liara. The maiden was still laid out on her bed, and anything that Shepard was going to say died in her throat as she took in the beauty of her body. She had fantasized extensively about what Liara looked like naked, but nothing she could have imagined came close to reality. Liara had full, firm breasts topped with hard nipples just begging to be sucked, a flat abdomen that Shepard ached to touch, and long legs that she couldn't help but imagine wrapped around her waist. But what drew her attention the most was the prize between Liara's legs. Glistening trails of wetness already covered her inner thighs and the swollen lips of her azure. Shepard's cock throbbed as she caught a glimpse of Liara's clit, fully erect and pleading for attention.

Her breath caught at the beauty of it all, but the sharp inhale also caused Liara's scent to flood her senses. She trembled with need as her instincts became overwhelming. Her entire body shook against the need to leap across the room and take Ashley's place between Liara's thighs. All that kept her rooted in place was the regret she had glimpsed in Liara's face. The last thing she wanted was to cause the woman she had grown to love even more pain. Liara had to have a choice.

"Shepard," Liara said softly. She pushed herself up, and this time, there was nothing but hunger in her black eyes. "Please..."

That was all it took. Hearing her name fall from those amazing lips snapped Shepard's control. She pounced on top of Liara, groaning as she settled over the woman who had been invading her dreams since that fateful day on Therum.

Liara welcomed her weight immediately, hooking a knee around her waist to keep her in place. Desperate hands clutched her shirt, pulling her close as their lips finally met. Somewhere through the fog, Shepard realized it was their first kiss. Liara's mouth burned, and it tasted even more intoxicating than her scent. Her heart soared, and she forgot about Ashley, about her doubts, about everything else. All she could process was Liara. Liara, kissing her. Clinging to her. Writhing against her. Because of her. At least, she hoped with every fiber of her being that it was because of her and not just their instincts.

Pulling away to breathe was painful. She wanted to lose herself in Liara's lips and tongue, but her lungs burned, and the soft, yielding body beneath hers was trembling so invitingly. Her hands roamed along Liara's naked skin, claiming as much flesh as they could. She cupped Liara's breasts, squeezing as the hard nipples pressed into the center of her palms. A sharp whimper cracked in Liara's throat, and she rocked her hips, trying to find purchase. Shepard groaned as the movement put pressure along the throbbing length of her cock. Even through her fatigues, she could feel the blazing heat of Liara's azure. Her shaft pulsed, and she realized why her competition had come so quickly. She already felt like she was about to burst. Poor Williams hadn't stood a chance.

Williams.

Shepard saw red as she remembered the way Ashley had looked on top of Liara. Her Liara. A growl vibrated in her chest, and she sank her teeth into the smooth line of Liara's shoulder. Temptation quivered through her, but she restricted herself to leaving a beautiful bruise instead of a mating mark. The slight pain made Liara buck harder. She tilted her head to the side, baring even more of her neck. Shepard took the wordless offer, leaving a string of bites along the slender column of her throat. Her hands moved down to Liara's hips, guiding them in an even faster grind.

"Shepard, please... Please, I need y-"

She didn't give Liara the chance to finish. Her mouth moved lower, scattering rough kisses and nips across the asari's chest. She needed to devour Liara completely, to leave her mark on every inch of flesh Ashley had touched and reclaim it for her own. She caught a bare patch of skin above Liara's breast, biting down until she earned a shout. When the sound shifted from pleasure to pain, she let go and tugged a violet nipple into her mouth instead.

It still wasn't enough. She needed to brand every inch of Liara's flesh, especially where Ashley had been. The memory of the dark stain on the front of Ashley's fatigues drove her down, down along the flat surface of Liara's stomach and between her thighs. They parted for her immediately, and she hauled them over her shoulders, not even pausing to look before she lowered her head. She inhaled, but only a faint trace of Ashley's scent remained. The rest was all Liara, warm and heavy and irresistible. Water rose in her mouth, and her cock ached with jealousy.

Liara's hands shot down to fist her hair, but she didn't need the encouragement. She latched onto Liara's clit, sucking harshly at the swollen ridge and grazing its root with her teeth. Another rush of honey ran down her chin, and she let her tongue dart down for a taste. The flavor alone was nearly enough to make her come, even without any stimulation. She had thought Liara's mouth was too delicious to give up, but the sweetness between her legs was overwhelming. She never wanted to leave.

Selfishness took over. Shepard abandoned Liara's clit, ignoring her cries of protest and covering her with flat, broad strokes. She gathered as much as she could, then searched for the source, burying her tongue in the clinging silk of Liara's azure. A fresh flood filled her mouth, and she clutched Liara's shifting hips, pinning them to the mattress so she could push as deep as possible.

The fingers in her hair tugged harder, and Shepard felt the warmth against her mouth pull even tighter. She gazed up along Liara's heaving stomach, and the beautiful face staring down at her almost stopped her heart. Liara's eyes were almost completely black, and ragged pants of air burst from between her puffy, well-kissed lips. A knife of desire pierced Shepard's abdomen as she realized that the omega was on the verge of a meld. It would be so easy to force her over the edge. To climb up over Liara, unzip her pants, and push inside. She knew it would be enough to join them completely.

But she had left it too long. Liara screamed, spilling over in a thick burst of warmth as her muscles clenched and released. Shepard caught as much as she could, too eager to taste Liara's orgasm to care that they hadn't joined. She let the rush of wetness fill her mouth and cover the lower half of her face, only pulling back so that she could suck greedily at Liara's clit and coax out more. She kept going until Liara was a shuddering mess beneath her, mewling with each aftershock that rippled through her.

Shepard immediately felt protective of her, but her own need was too powerful to ignore. Feeling Liara come in her mouth had snapped the final threads of her control. She surged up over Liara's body, caging her between her arms and diving in for another kiss. She promised herself that this was all she would allow herself, that this would sustain her until Liara's heat was over. But it was impossible to resist when Liara sucked her tongue, stealing the last bit of her own sweet taste. She couldn't help but imagine that wonderful mouth giving the same devoted attention to her cock, and the thought made it swell even more painfully against her already tight fatigues.

She shuddered when Liara's hand slid down her back, slipping around to cup the bulge in her pants. Instinct drove her to push against the exquisite touch, and she bit back a groan. Blood pounded hard along her shaft, making it more and more difficult to resist her primal urges. They were driving her to rip away her clothes and fit herself back between Liara's thighs, to ride the maiden until they were both satisfied and she'd claimed her mate, undisputedly and irrevocably.

Shepard barely had a grip on her inner animal, and that tether threatened to snap completely when Liara managed to open her pants, pushing them down far enough to draw her cock out from behind the soft fabric. The cool air of the room was like a soothing balm until Liara's fingers closed around her naked flesh, bringing her back up to boiling in less than a second. This was what she wanted more than anything, but it was also what she had promised to deny herself until Liara was ready.

Shepard froze, trying to draw enough breath to tell Liara to stop, but she never got the chance. Liara started pumping her, driving every other thought from her head. There was something about her touch, both tentative and eager at the same time, that drove Shepard absolutely crazy. Liara seemed to carefully measure her length, stroking from base to tip as she savored the feel of the shaft in her hand. Shepard tried to push her impatience down, but it was difficult. Every little touch forced all the breath from her body.

She growled when Liara's thumb swirled over the sensitive tip of her cock, smoothing out the slick drop of fluid that had beaded there. "I can feel you pulsing," Liara said in wonder, growing more confident.

"Because I want you," Shepard said, not caring how desperate she sounded. She may have been an alpha, but she still had needs of her own, and they were making her feel helpless. "I... I need to come."

"I want you to." Liara looked up into her eyes instead, and the desire Shepard saw there was nearly enough to undo her. "Tell me how."

Shepard was helpless to do anything other than comply. Her first thought was to pull Liara's hand away and thrust into her waiting azure, but that wasn't what her lover was asking for. And even though Shepard wanted to claim Liara, she also wanted to please her. She used the rest of her strength to push her torso away, allowing both of them a better view. "Faster. Stroke me faster." Her muscles tensed in pleasure as Liara eagerly complied. "H-Harder," she said after another minute of torture. More fluid spilled from the head, making it easier for Liara to move.

Shepard groaned as Liara held her tighter, grunting a little as she hit the perfect rhythm. "Fuck," she hissed through gritted teeth, throwing her head back as an intense orgasm gripped her body. She felt the tiniest bit of relief as the first jet of come spurted from the head of her cock, but it was Liara's surprised gasp of pleasure that made her pulse harder. Her head tilted back down, and she watched as she emptied herself over Liara's abdomen, thick ribbons painting patterns over her sweat-sheened blue flesh. And through it all, Liara never stopped pumping her hand, apparently just as desperate to take everything from her as she was to give it. She even managed to coax out a few weak spurts that Shepard didn't know she had left in her.

"Goddess," Liara breathed, still watching as Shepard's cock twitched in her hand. "You're magnificent."

Shepard reached down to pull Liara's hand away, pinning it to the bed as she readjusted her position. Soon, her cock was poised right against Liara's open and ready azure. She slid the head of her shaft through the abundant wetness, teasing Liara's entrance before pulling away to slide over the hard ridge of her clit. Liara rocked forward, trying to take her in, but she held back for a second longer. The hot, clasping muscles teasing her tip were hard to resist, but she wanted to savor the anticipation. She and Liara had been building toward this moment for months. Soft conversations, shared smiles, an extra hand and a lingering touch when one of them fell during a mission. The two of them had shared an understanding - once they stopped Saren, they would explore the undeniable feelings between them. This wasn't how she had pictured making love to Liara for the first time, but it was long overdue.

That thought stopped her just before her hips slammed forward. The red fog in her brain receded, and her thoughts snapped back into focus with startling clarity. Liara. She doesn't deserve this. Not for her... our... first time. Tears of frustration welled in her eyes as she fought against her body's instincts, trembling with the effort. Liara was completely open to her, and it would be so easy to sink inside. Stretch her open. Fill her with the heavy release pounding inside her strained cock and knot her to make sure she didn't lose a drop. Then, at last, Liara would be hers.

But the haze in her mind had receded enough to make her feel guilty. She remembered the way Liara had been with Ashley, wild and unrestrained. How could she know this wasn't more of the same? An asari omega's heat was nearly impossible to control. The thought of stopping was painful, but the thought of doing something to hurt the woman she had slowly grown to love was unbearable. With the very last shred of her willpower, she shifted back on the bed, away from Liara's quivering body.

"Shepard!"

The pleading note in Liara's voice and the blackness swirling in her eyes almost made her stay, but she held firm. Her conscience wouldn't let her go through with this, however much their bodies needed it. Liara's scent flared even stronger in her nose, trying to call her back, so she scrambled off the bed and stumbled toward the door, pants still bunched around her knees. "After," she said, her voice trembling with sadness and unmet need. "After it's over, I promise. I'll do this right... I'll - I want to..."

"No." Fear flashed in Liara's eyes, and she sat up, moving to chase after her. "Shepard, please don't leave…"

But she knew another second in Liara's presence would be her undoing. "Lock the door," she said, voice cracking with emotion. "I can't say no to you a second time." She rushed out into the medbay, hitching up her pants on the way. Her stubborn cock refused to let her do up the zipper, but it didn't matter. She had to put as much distance between herself and Liara as possible.

That distance proved to be a step beyond her self-control. She plopped down on the ground outside the medbay door and buried her face in her hands, howling with frustration, hurt, and loss. She wanted nothing more than to return to Liara's room and finish what she had started, but she couldn't trust herself. She had thought she was better than this, but something about Liara stripped away all her self-control. As the tears she had held back leaked from her eyes and dripped between her fingers, she hated her instincts and the animal they had almost made of her.


A/N: Some questions have been posed to us in the reviews/comments, so here are hopefully some helpful answers:

1. Why isn't there an isolation chamber on the Normandy? Based on the fact that there are omegas in the Alliance one would think a chamber would've been put in as a precaution.

Does this really seem like something a ship should waste space on? Truthfully, most omegas, embrace their heats and don't mind when it comes upon them. It's a natural thing for them and they usually satisfy it the way that nature intended. Liara's the rare omega who prefers to ignore and suppress her heats. Some of that is probably because she's used to spending a lot of time alone, so she's never really had to contend with alphas vying for her attention.

2. Why do suppression drugs need a Doctor to inject? I would think that such a drug would be more like insulin that a diabetic would take.

This point actually comes into play in our upcoming Aria/Tevos Omegaverse story. These drugs are not meant to be used for long periods of time, and are actually kind of dangerous. That's why not everyone takes them. If taken without doctor supervision, especially over a long period of time, various bodily functions can begin to shut down. Liara also needs to take a higher/potentially more dangerous dose than usual because the only ones on the ship are meant for humans.

3. Why didn't the Doc have an extra within reach for Liara to get in cases of circumstances where she can't administer it herself?

See the answer for Question 2.

4. Knowing her heat, why did Shepard ask for Liara to show up instead of just having her "dial in" via omni-tool? Joker pokes in via communications instead of showing up in meeting rooms after all.

Because Shepard is a bit dense. xD; And sex-addled. And she probably convinced herself that just being in the same room as Liara couldn't be too harmful, right? Right? The temptation just to see and smell the woman she wants so badly probably got the better of her. Also, there's precedent for everyone to be in the same room, and Liara wasn't technically confined. She was taking a drug regimen to control her heat and theoretically free to roam the ship as she pleased at that point in the story. There was also a scene that we had to cut from Shepard's POV where she's just trying to keep things as normal as possible. We originally had a scene where Shep was debating with herself on inviting Liara to the meeting and finally deciding to because of Liara's plea that the Normandy was her home, but we cut it. So Shep was trying to do what she thought Liara would like best.

5. And why in the world did Ashley barge right in especially knowing what she knows about the Liara/Shepard relationship - something that she started to say before the dry humping started.

See the answer to Question 4. Because Ashley is a bit dense. xD; And sex-addled. That's why. Also, the door automatically opens when you get close to it and Liara forgot to lock it.

6. Do the alphas in your universe go into ruts?

We hadn't thought about that. It's not part of traditional Omegaverse lore. But the concept is hot. *cough* However, 'Cat has come out firmly against it unless and until we can come up with a more complete story surrounding the disaster that ruts could be. So, short answer: No, the alphas do not go into ruts in this universe.

We hope that this explanation clears up some/any confusion you readers have out there. And please allow us some leeway as even we refine our vision of what this new universe looks like to us. Anyway, we hope you enjoyed the read and comments or reviews are always welcome.
