Surprise Mate
Alpha!Robby x Omega nurse!reader
CW: Omegaverse AU, 18+ MDNI, smut, breeding kink, knotting, slightest mention of blood, pregnancy, and slight cringe I’m sure lol
Note: Just so yall know this is the first time I’ve written an omegaverse fic in an extremely long time I’m talking 10-12 years but this was inspired by @titus-danforth ‘s February fic fest list. I haven’t touched this genre since I was sold to one direction for my moms drug money and I had to go on tour with them! Hope it’s good tho I wrote it on a whim last night not really re-read so probably grammar and spelling mistakes… ENJOY!
************************************
Being an omega in the ED was not an easy feat. It came with a lot of paper work and keeping your designation low in the “need to know” category for your coworkers. You were a nurse and therefore reported to Dana Evans, which is why she was one of two others that knew. The others being Gloria and HR of course as they needed to be aware of upcoming time off for your heats, as well as monitoring your usage of suppressants and scent blockers. The suppressants were for dulling your senses around Alphas, and the scent blockers were patches that went on top of your scent glands to block detection of designation. While all employees were mandated to use scent blockers, they affected omegas differently. Using too many at a time or for too long can tend to have the opposite effect than their intended purpose especially when paired with suppressants. In the case of overuse it had been known to bring on an omegas heat early, a direct consequence for suppressing a cycle for too long.
Unfortunately it is a consequence you found yourself walking on that very dangerous line. This was due to you picking up an abundance of extra shifts and doubles for the last week due to short staffing crises. The Pitt had been hit with an influx of patients and too few workers to cover. So you had attempted to help pick up the deficit, and the extra overtime paycheck couldn’t hurt either. At least that's what you told everyone who asked why you were staying so busy and working such insane hours. But the real reason that you kept coming in day after day was because a certain attending by the name Dr.Michael Robinovitch was also picking up some extra shifts.
The moment you started working at the Pitt in the ED you were absolutely enamoured by him. From his broad shoulders, his sweet doe brown eyes behind his readers, and the strong Alpha presence that could command attention at every corner without seeming overbearing had done you in. No need to even get started on his scent that you had caught lingering at the end of a grueling day a few times; the warm sandal wood mixed with worn leather, and a seductive undertone of amber had you salivating. However, It wasn't something you were able to catch often or even very strongly as the suppressants dulled your senses considerably, but when you did you bathed in it. The Omega in you was practically purring at every whiff. And your encounters with Robby were never lacking.
At first you thought you were imagining things. Just a hopeful dream that he was paying attention to you, but after a while of working with him you began to notice that every time you were scheduled together, you were always placed on the trauma team. And in addition if a code blue was called or if Robby needed help at the drop of a hat, it was always your name he called first. You also discovered that he was a very hands on man which was puzzling at first because you watched him flinch or shy away from contact with others. Although with you it was mostly in the sense that if you found yourself in his three foot orbit, his hands would somehow find their way onto your body. Never in an too obvious (at least to you) way, or an I need to contact HR way. Instead it was a brush of your fingers when handing off the tablet or a grab at your hips to move you around was always occurring. And while it was an often enough occurrence that it never surprised you, it never failed how every time he touched you it would send warmth coursing through your body. Which then ended with you excusing yourself as you rushed to replenish your scent blockers as your need would bleed through.
Today though, you rarely had a moment to breathe let alone focus on your body and the effects of your over tired brain we’re having. Or even notice how Robby’s proximity was having a very strong impact on how you behaved. All you knew was that the ED was unbearably hot in the middle of a Pittsburgh January. But all in all your shift began about as normally as any other, a little more exhausted than normal but no less ready to begin your day.
Dana however, took one look at you and immediately pulled you to the side, “Look honey, I’m real grateful that you're willing to help us out but this is day six in a row for you and Im worried your overdoing it,” she had her arm around your shoulder as she attempted to keep her voice low enough so that only you two could hear.
It was sweet of her worrying about you but you felt like you had it under control, and a little part of you still craved to prove yourself as a somewhat undercover omega in the ED. So you shrugged off her concern, “Dana I promise I'll be okay, it's nothing that I can't handle, plus I'm not due for my heat for another three weeks. Trust me, I wouldn't be here if I thought it would go wrong.” You kept your voice soft and aloof for reassurance.
It was all a lie though. You knew your heat was actually creeping up later in the week, and you knew you were at the end of your energy rope so to speak, but for some reason the thought of not working while Robby was had felt like a knife settling in your stomach. You weren’t sure when that feeling had truly begun to make itself known within your gut or why you were feeling this way all of a sudden but the last thing you were going to do was tell Dana.
Speaking of which, she seemed to believe you and agreed to let you begin your shift, a decision she may or may not regret in a few hours. Because two seconds into standing at the nurses station she had to clean her glasses and do a double take because she was pretty sure she saw you subconsciously scent Robby's jacket that was hanging over the back of the chair you had just sat in. Nothing too noticeable but you had leaned back in a way that seemed as if you were simply stretching but just before coming to sit back up you angled your head to slightly rub the soft fabric behind you right where your scent gland was covered by the patch. And this wouldn’t be the last time that Dana found herself observing odd behavior from you that should've alerted her to your predicament.
Over the next few hours she notices that you and Robby seemed to almost revolve around each other (more than usual). Except it was less gravitational and more primal. If you were engaged in a conversation with another alpha, or even a beta, while he was around she took notice of how he angled himself slightly in front of your position effectively placing himself between you and the other person. Dana also noticed that while you were normally independent when taking action with your patients and their care, today you seemed to seek out Robby's approval at every chance you could. And while this had confused Dana she was left to her own devices as she contemplated the two of you’s behavior. Because you had barely been aware of your actions and unmitigated bodily responses today. And when you had caught yourself the attempted intervention and cover up was a little too late.
**************************
It was the last few hours of your shift, and if you asked anyone here they would say today was rough, but for you it was a whole different ball game. It started when you caught yourself rubbing against Robby's jacket for the third time in a singular hour, a behavior you had never displayed in your life not once since presenting as an Omega. While you knew it was a normal pre-heat behavior, it was not one you particularly found yourself ever participating in until today. Quickly you began looking around to see if anyone caught your movements. And soon letting out the breath you had held when you noticed it had gone unseen by those around (or so you thought). Hastily jumping up you all but sprinted to check on bay five to distract yourself from falling back into the jacket. Unbeknownst to you a certain Alpha attending had clocked your behavior in seconds, and if there is one thing to know about Michael Robinavitch it would be that he is a well educated doctor. One who is absolutely able to spot an omega in heat just off of their slight behavior displays. Behaviors such as scenting, which is exactly what he caught you doing.
Now as a doctor, and an Alpha, Robby would say he is well versed in the code of conduct he is sworn to work under. Always claiming to respect that oath each time he clocks in. But when he catches his favorite nurse rubbing all over his jacket like a good little omega should for her alpha, he feels the realization of the situation snap in place. The realization that not only were you an omega that hid as a beta this whole time, but when he brought that jacket to his nose Robby realized that you were his omega. And you had been hiding under his nose this whole time. An all consuming emotion he never thought he would feel at his age rushed over him igniting a cacophony of instincts.
Since Robby hit his 50’s he had come to terms with the possibility that he would never find his mate, sure there was still a part of him, the Alpha part, that would always feel that loss. But when you came around he found that he was more than happy to forget about the pain of not finding his omega if that meant he could spend the rest of his life with you near him. Which now that he thinks about it should have set off a warning bell. But now he knew why, now he understood that a part of him recognized you under all the suppressants and scent blockers, and now that he knows, he wasn’t planning on ever letting you go.
For the rest of the shift he would take every opportunity to subconsciously rile you up. On any given day he would normally make an effort, small touches here and there, but now he decided to up his game. An idea that was spurred by what he caught you doing. While he would typically touch your shoulder or hip while still maintaining distance when passing by, Robby decided today he would happen to drag his chest across your back every time he passed you. This was his way of subtly scenting you back. He also decided to test the waters today and lay it heavy with a few pet names he often used with you. Sweetheart, kid, or honey were what he addressed you as today, never once by your name like he would before. What he was doing was working and he could tell, especially as he sensed your temperature rising under his fingertips as the shift dragged on and the slight sheen of sweat that gathered on your brow. Or how even though you were constantly changing your scent blockers, the tell tale waft of your pre-heat, that warm sugary vanilla, was filling his senses even under the strong antiseptic smell of the patch. He was just waiting for the most opportune time to arise for him to make a move.
And while Robby was plotting, you were panicking. All day your mind had been stuck on Robby's warm hands, the little pet names he was calling you, and how his scent all but slapped you in the face. Even though you triple checked you had taken your suppressants this morning and changed your patches multiple times. You knew you should've gone home early under the guise of sickness, but when you mentioned going home to Perlah and Princess you heard a deep baritone voice call your attention, “Oh ho ho, absolutely not sweetheart, you wouldn’t leave an old man like me without one of my best nurses to help would you?” Your mind went blank, and if the counter you were leaning on wasn’t there you would have immediately dropped to your hands and knees in front of everyone.
Realizing you had been silent way too long while staring at him in shock, you managed to splutter out a reply, “I… uhm, no for sure. I w-was just uh, I was just saying ill be okay j-just a stomach bug!” Whatever slyness you thought you had achieved was broken by the high octave your voice reached the longer you spoke.
Quickly you shut your mouth and looked down at the papers in front of you, causing you to miss the sight of him walking closer. That was, until you felt a hand lift your chin and your gaze was once again met by the deepest brown you had ever seen. Suddenly a low “Good girl” was softly thrown out before he breezed past like nothing happened. This interaction ended in you once again running off and changing your blockers for the fourth time, and a change of underwear for good measure as you noticed a small amount of slick gathered at the center.
You had made it to the last half hour before you felt the first cramp rack its way through your body, and it was strong enough to halt you mid step and bend forward just slightly in an attempt to relieve the pressure. Your mind was already beginning to fog over as your heat slammed into you almost full force too early and too quickly. A direct consequence of the overuse of blockers from today and the past week, the very thing you had sworn to Dana that you had under control. Out of the corner of your eye you see Dana start rushing over toward you as your scent was leeching into the ED. However she got exactly four steps before a deep rumbling growl had everyone within five feet of you taking 10 steps back. In response to the sound your temperature rose even higher and you blindly reached out behind you at the same time Robby had come up behind you and immediately scooped you up into his arms.
Noticing everyone's eyes he let out another warning growl before everyone jumped and looked away, he then turned to Dana and grunted out, “Call Abbot im taking her home.” Dana, however, looked almost like she was ready to call Ahmed in to separate the two of you as her main concern was to make sure you were consenting.
But before she could call him over she looked at you and noticed that at the sound of Robby’s voice, Dana could hear your chest begin to let out a slight vibrating purr in response followed by a whine, “Alpha, p-please.” Nodding her head in approval it took him two seconds before he swept you away to take you back to his house.
The ride there was a blur as you were focused on the blinding pain that came in waves as the cramps only got worse. It wasn't until he carried you out of the car that you gained some semblance of self at his touch. Instantly you began nuzzling your nose into his neck breathing his scent in deep. A scent that due to your full blown heat your body had burned through the suppressants and his scent was stronger than ever. You faintly heard him let out a grunt as you licked a stripe up the length of his gland. The sound of a door closing followed and soon after a couple of twists and turns down hallways, you were laid on your back to meet a soft bed.
Warm hands were then felt creeping up your scrub top as your lips kept repeating “Alpha please, Michael please I need you!” Your begging went straight to his groin as he tried to not to let the feel of his oncoming rut scare you, but damn you for calling him by his name.
Because the moment his name left your lips he grunted out a rough ‘Fuck’ and the loud tear of your scrub pants and underwear echoed off the walls. Peeling your lids open you saw him gather up his saliva and spit on his fingers before he allowed himself to begin exploring your cunt. It took him a total of two seconds before he expertly located your clit and began circling the bundle of nerves in well measured movements.
“Fucking hell kid,” his groaned in effort as he tried to start out gentle, “I could smell you all goddamned day, saw you scenting my jacket like a good little omega, drove me fucking crazy”
His fingers lowered arriving at your entrance, he sucked in a sharp breath at the feeling of your slick dripping down onto the bed below. And before he could stop himself he sank down to his knees. After hitting the floor he surged forward attaching his lips to your clit in replacement of his fingers as he buried two deep within in one swift movement.
“Ugnh fuck YES Alpha!” your voice ripped out of your throat as the feeling of his two fingers filled you, this was in addition to the figure eights he was drawing with his tongue coupled with expertly timed sucks and small bites. Your core was already clenching as your first orgasm rushed closer, but it wasn't until he crooked his fingers up into that soft spot that had your peak shooting through you with no warning.
“That's it ‘Mega, just like that kid,” his voice was rough before he dove right back in, not coming back up until your second orgasm followed closely behind. However, while he wasn’t showing any signs of wanting to slowing down, you needed more, you needed to feel him inside of you. Needed to be filled with him.
Grabbing a handful of his hair you began to tug him up, “I need you, please, need your knot alpha” your voice was breathy as you began reaching at his bottoms.
“Look at you,” he tutted at the sight of your hands desperately trying to get ahold of him, “so desperate for your Alpha to give you what you want hmm?”
After another moment of watching your struggle he decided to help you out leaning back he stood up and tugged off his pants and top, immediately feeling your hands trace his chest as you sat up to touch him.
“Go ahead baby, take what you want,” he whispered as your hand gripped him through his briefs before pulling them down and watching as his length bobs up. The sight of him was enough to break through the haze of your heat as you take in his very impressive length and girth, a little nervous it wouldn’t fit. Sliding off the bed and dropping to your knees you took a moment to appreciate his body, the wide span of his shoulders down to the softness of his tummy and the dark trail of hair that led right to where you wanted. His length was adorned by dark unruly curls and down the underside of his shaft was a very large and prominent vein, this led to the bright red swollen tip beading with arousal.
Leaning forward you lightly hold the heavy weight of his sac in one hand as you grip his shaft with the other, starting with a few kitten licks cleaning up the mess he was making before flattening out your tongue going from base back to tip wetting his length fully.
“Just like that, holy fuck yes!” Robby’s head tilted back as you wrapped your mouth around him, taking as much as you could and using your hand for what you couldn’t. One of his hands came up to the back of your head, not to push just to hold feeling like he needed to be touching some part of you at all times. Meanwhile you were giving it your all, the salty taste of him and the feel of his knot swelling at the base spurred you on. But just as you lightly raked his length with your teeth followed by a flick of your tongue beneath the rim of the head, Robby was immediately pulling you off with a gasp.
“Hold on now don’t want to cum too early,” he quickly pulled you up by your hair just as you had done with him earlier and brought your lips together in a rough kiss, teeth clacking and the taste of each other mingling on your tongues. Robby began guiding you back and lifting you onto the bed once more.
Once your butt hit the mattress you didn’t even need to be directed as instinctually you scooted back and flipped onto your hands and knees lowering your front to the mattress and arching your back in an invitation for him to follow.
“Look at you, such a good Omega presenting without even being told,” his hands came up to trace your curves as he pressed the occasional kiss to your spine as he worked his way up your body.
“Gonna take my knot aren't you,” Robby leans over you and nips the side of your neck right above your gland, “Want your Alpha to fill you up until it takes huh? Gonna get you all full until you’re stuffed and leaking for days”
You were whining in agreement desperate for him to follow through with these promises, wanting nothing more than for him to give you everything. The heat that had gone down with your two previous orgasms was rising once more. Sweat gathered at your brow as you concentrated on trying to stay still while you waited for him to do something, anything. But he caught you by surprise when he asked,
“You know what we are right ‘Mega?” he questioned as he gripped himself tight, and began lining himself up his other hand gripping your hip.
Turning you head to the side so your cheek rested on the bed you looked back at him nodding your head as you whisper, “Mates…were mates,” pausing as you feel him rub his length against you and he let out a shuddering breath at hearing your words, ”I’m all yours Robby”
“That’s right baby, all mine no one else’s,” Slowly he began pushing in, even though you were soaked with slick and positively dripping he was still a very large man. “Fuck I’ve waiting so long for this, for you,” he whispered as if he didn’t mean for that to slip out before refocusing on guiding his length. The last thing he wanted to do was hurt you but your heat and the admittance of being mates was pushing his rut to the forefront of his brain.
“Doing so good for me, sweetheart” Robby thrusted in a few more inches before he heard you gasp and whine at the stretch, he paused a moment before continuing,
“Shh, just a little more…” and before you could show your incredulity at the fact he wasn’t fully in, his hips snapped forward once more, burying himself to the base.
Both of you let out a mix of curses, but then you smelt it. Beneath the warm sandalwood, leather, and amber was the scent of his rut building. A hint of spicy cracked pepper was mingling with the heavy warm vanilla of your heat. So you did the most rational thing you could think of, you leaned forward off of him just a little before dropping back down, hard.
This seemed to give you the results you wanted because before you could lean forward again a hand gripped the back of your neck pushing you into the mattress and keeping you still.
“My sweet little omega wants it rough huh? Practically begging me to take what I want is that it?” He cooed down at you before he began snapping his hips at a brutal pace.
“Yes-uh.. P-plea-se” your words were interrupted by each thrust as his hips met your ass, “M-michael harder-r”
His chest rumbled with possession, one hand on your hip and the other still firmly on the back of your neck. He brought his left foot up on the bed beside you for more leverage. With this new angle you could feel his tip bullying your cervix with every thrust, and the sound of his hips slamming into your ass echoed.
“Youre taking me so well baby” using the hand he had on your neck he maneuvered your upper body up so your back was against his chest. You could feel his base swell as his knot forms catching on your cunt as he pulls back and pushes in.
“Want me to fill you up don't you, want me to give you everything I have huh, want me to mark you so everyone knows who you belong to?” you were lost to his words and movements barely able to form a thought, the best that you could do was nod. But Robby, no he wasn’t having any of that. He pulled out just enough so that his developing knot bumped your entrance as he began thrusting shallowly. Never pushing all the way in, which had you attempting to push back onto him fully. Moving his hand once more so that it wrapped around the front of your throat and he guided your chin up and out as he nipped your gland once more effectively stilling you.
“Say Please” he growled, emphasizing his words with a squeeze of his fingers at your throat
“Fuck, please Michael…” letting out a pitched whine at the loss of friction, “ Alpha please make me yours, please!”
The rest of his restraint snapped at the last please, picking up his pace once more and moving the hand at your hip down your front as he began toying with your clit. His brutal pace moving in harmony with the circles at your overstimulated nerves, your cunt began spasming around his cock signaling your incoming orgasm. A final few thrusts were placed before he pushed in for the last time before his knot swelled fully locking him into place. As soon as you felt the first ropes of his cum flood your walls, Robby's teeth sunk into your gland, releasing a flood of endorphins and hormones as you flew head first into your third orgasm, mouth wide open in a silent scream.
“Fuuucking hell, that's it, take it all kid just like that” he whispered as he released your neck and lathered his tongue across the rivulets of blood dripping from the fresh wound. You were barely able to register your body let alone what he was saying. And you were pliant as he moved both of you to lay on your sides. Hooking your top leg back and over his hips as he began rubbing his hand around the small bulge in your lower stomach.
“Your going to look so good stuffed full of my pups, gonna keep you stuffed and leaking every single day so every one who sees my mark can smell me dripping out of you with every step” his statement was emphasized with the continual spurt of his hot spend that seemed to never end.
Letting out a soft whimper once more you nod blubbering nonsense as your omega was satiated to its fullest, your heat was taken care of by your alpha, you were stuffed full of him, and now you were mated. You were practically vibrating as you began the rumbles of a purr in your chest once more before drifting off to sleep
***************************
It wasn’t long before Robby had you moved into his home and a four carat emerald cut ring sitting pretty on your ring finger. In fact it was exactly 6 weeks that he accomplished this because the first week you lived together Dana and Jack had thrown you an engagement party. One that ended in Dana winking at you while handing over a pregnancy test saying, “I already know but just to be extra positive.”
And of course an hour after you got back home with Robby you took the test and watched as his eyes twinkled with unadulterated joy when you showed him the most positive test you'd ever seen. That shared joy however became pure rage directed straight at Robby when you went to your first ultrasound and found out there were three heartbeats ringing loud and clear. And all he could do was stand there with a dumb smile on his face as his iconic red blush moveing up his neck and onto his cheeks,
“Whoops?”
