Chapter Text
The first wave of heat hit the cyborg like a punch in the chest, heat blossoming out from his gut that left him sagging against the wall. The crimson warning beacon blared angrily at him from within his visor.
Internal temperature increasing.
Abnormal fluctuation in hormone levels detected.
Immediate action is advised.
The same message had been scrolling across his info feed for hours. Now he was starting to wish he'd gone to Angela when he'd had the chance. The doctor had been called away on business a few days ago, and there had been no news about when she would return.
The second wave was worse. It knocked him to the ground as an explosion of heat in enveloped his core. His vision blurred, vents on his shoulders activating with a hiss. Hands scrabbling to purchase on the smooth floor.
What is-
-Something wet coated his thighs, dribbled down his thighs, sending shivers racing up the youngest shimada’s spine. The heavy feeling between his legs something he hadn’t experienced in years.
“No,” Genji’s wail came out hoarser than usual. Heavy and metallic. “Nononono not now! I can’t...I shouldn’t be able to-” Even with metallic fingers there was no way he could mistake the feeling of slick on them, coating his thighs. And that could only mean one thing.
Something he never thought he would experience ever again.
His heat was starting.
The third wave forced the air from his lungs, a single drawn out whine that echoed throughout the empty hallway. The lingering scents of all the others melding together in one thick soupy mix, only surpassed by the sharp tang that was unmistakably Alpha.
Alpha.
The word alone made every nerve in his body sing like they’d been shocked to life. And it wasn’t just any Alpha’s scent Genji was focusing on. It was yours. He’d always found your scent enjoyable, calming even. But now...
The smell of burning wood and cloves filtered through the cyborg’s visor, urging him to his feet again, calling him. That all too familiar scent leading him blindly down the corridor, legs barely able to support him. Poor Genji practically collided with the door to your room, too busy following his nose. Another groan, muffled by his mask, drifted through the hall. Fingers pushing incessantly at the keypad. He needed to get in there.
What was the code? Whatwasthe-
-The door flew open with a hiss, and Genji tumbled inside.
~ • ~ • ~ • ~ • ~ • ~ • ~ • ~ • ~ • ~ • ~ • ~ •
With a nod and an exhausted wave you bid farewell to your teammates. Although the previous mission had been a success, things had been touch and go for the longest time. The constant stress threatening to break you down at any moment. Even so, you’d somehow managed to get the job done early. Returning to base a full two weeks ahead of schedule, and you couldn’t wait to get back to your room.
While everyone else rushed off to fill their bellies you just wanted to shower and collapse into your warm, soft bed. But, for you, food could come later.
You slapped your hand against the keypad, frowning when it didn’t open right away.
Did I lock this before I left?
Your brows came together in a frown, but no matter how hard you tried it was impossible to force your sluggish mind to remember anything with the promise of sleep so close. Your fingers skimmed the keypad, entering the code with practiced ease as you hike the duffel bag higher onto your shoulder.
The door slid open allowing a massive wall of steam to escape, slapping you in the face.
“What the…?” Eyes wide you stormed in, allowing your duffel to fall to the floor with a thud, forgotten. A thick curtain of steam had settled in your room, perfectly sealed inside by the door. Turning your room into a makeshift sauna. The moisture clung to your hair and skin as you pushed your way through the smog, the constant heat making it hard to breathe. Bits of metal scattered haphazardly across the floor. Metal that seemed oddly familiar for some reason. You frowned, waving a hand before you in an attempt to disperse some of the steam.
Is someone using my shower?
It was the only thing you could think of.
But there was something else. Something lurking beneath the heavy scent of steam that had caught your attention. Tilting your head back you sucked in a deep breath, filtering through the myriad of smells around you. Dust, That orange scented furniture polish you were forced to use, the mint oil diffuser zenyatta said was would help relieve your everyday stress, and…
….Oh
A growl rumbled low in your throat, you knew that scent. Incense and metal amplified by the unmistakable odor omega’s secreted while in heat. You’d encountered omega’s in heat before, it had become a part of your life. Especially with so many agents living together in such close quarters, but this time it was a particular omega. The one you’d been harboring...particular feelings for. The one whose scent seemed to have invaded your room during your mission.
The younger Shimada brother and all around cyborg ninja.
Genji Shimada.
“Genji?” You swallowed hard, throat dry and tongue thick. Why were you suddenly so nervous? “Are you in here?” A resounding whine was your answer, needy, bordering on pained. It drew you further into your room, around the corner towards your bed.
And there he was, sprawled out on your bed in a net of his own making. A nest that was nearly completely built out of your clothes. You didn’t bother to hide the possessive growl that rose up from within. The sight of the male on your bed, snuggling into a nest made of your clothes. Back arched, legs spread wide, the cyborg turned toward you and moaned. Loud. One hand stroking the metallic rod that served as his cock, the other knuckles deep in that glistening cunt.
Angela gave him both? Fuck!
He flushed, but didn’t stop his movements. Smearing precum down the ridged shaft pulsing in his grasp.“You...weren’t supposed to be back so soon…” A shiver ran through him and he bit his lip to keep from crying out. Only now did you realize that he wasn’t wearing his visor, face bare and shining with a thin sheen of sweat. “This-I didn’t think this could happen anymore-”
You took a step forward, lured closer by the the heady scent. Just as alluring as the Omega who was secreting it. Genji had never gone through a heat as long as you’d known him. Truthfully, you had just come to believe that the ninja was taking heat suppressants to avoid the situation all together. But, now, seeing him so spread out and obviously needy on your bed left you feeling a little conflicted.
What were you supposed to do? Sure, the Alpha part of you was practically begging to ease him through his heat. Have him writhing beneath you, clawing at the sheets as your knot locked the two of you together. Voice cracking as not even his synthetic vocal cords could handle the strain. You licked your lips.
“-Do you want me to leave?” You blurted out, tearing your eyes away from the precum beading at his head. It might be your room, but you could at least afford to give him some privacy. “I can..” You swallowed again, glancing back towards the door, “Go get someone--Angela?” His scent began to invade your senses, even stronger than before.
Genji smirked face flushing as his scent spiked again, spreading those legs of his even wider. For some reason you weren’t surprised at the ninja’s flexibility. “Actually…” Genji took his time withdrawing his fingers, making a show of smearing his juices all over his slit before spreading those puffy, synthetic lips for you. Core, bright, slick, and green. “Would you be willing to help me, Alpha?….my beloved Alpha”
You nearly tripped over your pants in your rush to be rid of them.
The cyborg’s grin was all teeth as you pulled him onto your lap, and he wasted no time attacking your neck with sloppy open mouthed kisses. Making his was up to your jaw before sealing your lips with his own. You groaned, pushing back against those scarred, puffy lips in earnest. Forcing your tongue into his mouth, drinking up his whimpers of approval. He fought back of course, refusing to back down in the slightest. Genji was going to make you work for every whimper you pulled from him.
While Genji was distracted by your tongue you ran your hands down his back, rubbing at the mixture of both organic and synthetic flesh. Reveling in every twitch and shiver you caused. Slowly, your hands made their way past the curve of his back and down to his hips. Digging your fingers into the supple flesh of his ass, you hauled him up. Your lips separated with a pop, a single strand of saliva the only thing connecting you. “Are you ready for me, Genji?” Heat or no heat, you still wanted to make sure he was alright with all of this--with having you.
A mischievous glint appeared in his eye and Genji snorted, angling his hips to grind his slit against your dick,already thick and throbbing much like his own. Taking great pleasure in the sounds you made, “Is that a serious question?” Did you honestly think he’d be here if he didn’t want to be?
“Alright then, fine.” You ground out. If that’s how he wanted to play, two could play that game. You lowered your head, peppering his chest with kisses as you slowly slipped your cock past his folds. He gasped, arching into you as his hands flew to your shoulders, grasping desperately, kneading your flesh. The man moaned like a porn star. You took him slowly, inch by inch, until he was shaking by the time you’d fully sheathed yourself within him. Little needy whimpers breathed into your ear as he urged you to move.
But, you didn’t.You sat perfectly still and busied yourself by nibbling at his throat. You had to bite down harder on the synthetic muscle to get the same reaction, but the sounds Genji made were well worth it.
“Pleeease.” He sobbed, metallic fingers clutching at your shoulders. They would surely leave bruises later. Your iron grip on his hips kept him from moving, “Move!”
You pulled away, eyeing the marks on the cyborgs neck with pride before pegging him with a glare, “Next time, don’t be a smart ass if you still want me to fuck you.” You emphasized your point with a snap of your hips, smirking at the way his body seized up, back arching and mouth open in a silent moan. He nodded furiously, babbling apologies as you launched into a rapid pace. Deep punishing thrusts that had the cyborg clinging to you for dear life.
“Please...please!” His voice cracked as you bounced him up and down, muscles coiling tighter and tighter. The wet sound of skin on skin filling the room. Smirking you maneuvered a hand between your bodies, palming him. It felt rougher than you expected, the synthetic skin grabbing at the flesh of your hand.
Slowly, you could feel the knot at your base starting to swell, ready to be buried within the Shimada riding you. You groaned, “ Are you ready for me, Genji?” palming him as you bit down on the juncture between his neck and shoulder. “I’m going to mark you, inside- make you mine, forever.” A growl bubbled up from your chest at the thought, “ Fill you up so much there’s no way you won’t be having my pups.” He nodded, a tiny whimper the only response he was capable of making. Eyes screwed shut, lost in the pleasure building inside him Genji had never looked more delicious to you. Whimpering desperately as your knot kissed his entrance with every thrust.
Without warning you slammed up into him, locking yourself in place with one sharp thrust, hissing through gritted teeth as you spilled deep within the cyborg. Hips jerking erratically as his walls twitched around you, trying to draw you in even further and milk you for all you were worth.
Genji howled, clawing at your back, feet digging into the sheets as his own orgasm tore through him. Scrambling his system and sending shocks of pleasure all the way to his toes. Clear, sticky fluid splattered across his chest, glistening against the mix of metal and skin. He jerked once, twice, and then sagged against you. Nuzzling against your neck with a content hum, making himself comfortable even as you continued to twitch inside him. He wouldn’t be able to move anytime soon even if he wanted to, not with you situated inside him so snugly.
Slowly, you maneuvered yourself onto your back, Genji lying on top of you. The light sheen of sweat on your skin making you shiver. Idly, you began rubbing his thighs while waiting to catch your breath. So, you were more than shocked when Genji suddenly pushed himself up before grinning boyishly down at you as he licked his lips.
“Don’t tell me you’re finished already?”
