SOMETHING IN THE AIR

A soft yawn escapes your mouth as you scribble down notes. Moira had asked you to stay up late to finish up some tests on one of her projects. Being her lab assistant has certainly impacted your sleeping schedule, but it is still a job that you enjoy. You were, however, on a need-to-know basis on most of the experiments and projects, which usually meant you weren’t given many details. Currently, you’re supposed to be working on a type of venom that disables any abilities one has, such as Moira’s own grasp.

A soft knock sounds on the lab doors, and you call out to the visitor. You lift your head up from your work as the door opens and smile when Genji stands there. He holds a glass of water in his hand, sweats and a long sleeved t-shirt on his body, and a black fabric mask over his face.

“Hi, Genji,” you greet him sweetly. You drop your pen and walk around the lab table to get to him. The two of you have been friends for a while, but ever being anything more was tricky. You’d be lying if you said you have never thought about him in a romantic sense, but you hardly felt like it was something possible. The two of you kissed once, a soft and sweet, two second kiss that was interrupted, but nothing more. It’s tricky to date in Overwatch, and emotions make things complicated. Though, there are some nights you found yourself wishing the kiss was never interrupted.

“I brought you this. I’m sure you’ve been drinking coffee all night, so it’s time for some water,” Genji passes the glass to you, the ice clinking with the movement. You turn to look at your workspace, seeing two coffee cups sitting there. He knows you well, and it never fails to warm your heart.

“Thank you,” you whisper, taking the glass and placing it on the lab table next to you. Genji nods, taking a few steps back. You watch him retreat, the silence between the two of you making your heart ache. It was never like this before the two you kissed.

‘Genji, I-” you start to say, but he takes a few steps to the left and runs his hand along one of the shelves. You watch his movements as he gently touches each of the bottles on them.

“What are these?” He asks you. The bottles are full of liquids of different colors, each with different effects.

“Uh…old projects, I think,” you say. The dark blue liquid in the bottle Genji touches was a paralyzing agent, used for a mission that Moira went on. Some of them, though, you don’t recognize. Some of them probably have labels written on the bottom, but they are typically in some sort of code, so only Moira and, occasionally, you can read them.

“Did you work on any of them?” Genji asks, his dark eyes connecting with yours from across the room.

“Some of them, but nothing near what Moira has done,” you mutter. You’re her assistant, so you are essentially in her shadow.

“I wouldn’t exactly say she’s the best role model,” Genji says, his hand stopping at a bottle full of a cloudy pink liquid. He pulls it off of the shelf, seemingly interested in this one. “This bottle isn’t like the others.”

You frown, taking steps closer to him until you are close enough to properly examine the bottle in his hands. He holds it carefully, making sure not to drop the glass, but you notice that he’s right. The other bottles have caps or corks keeping them sealed, but this one seems to have been melted shut, like Moira didn’t want to risk any of it escaping, even the fumes.

“Hm. I haven’t noticed that before,” you say, reaching up to take the bottle from him.

“You didn’t work on that one?” Genji asks, watching your face closely. His eyes seem to shimmer when you look up at him.

“No, not this one,” you flip the bottle around softly, trying to read the bottom, but you somehow lose your grip and the bottle clatters to the ground. The sound of shattering glass fills the room, and you watch with wide eyes as the pink liquid bubbles as soon as it touches air, the liquid evolving into fumes. The pink air flitters around, seemingly wrapping its tendrils around you and Genji.

“Fuck,” you whisper out. You’ve broken plenty of things before and, while Moira wasn’t happy about it, she understood that accidents happen. This, though, is different. You don’t know what you just released. “At least we aren’t dead.”

You drop to your knees after the poor excuse to lighten the mood (though, it’s true, some of those bottles would have killed both of you), and dig through the glass shards.

“Be careful!” Genji exclaims, dropping to his knees with you and wrapping his hands around your wrists. He tries to pull you away from the glass, but you manage to find the shard that has a piece of tape on it. You flip it over, and immediately wrangle yourself free of Genji’s grip when you see the label. Aphrodisiakos. A project you had only heard about, one where Moira was tasked with creating an aphrodisiac.

“You need to leave,” you shudder out, trying to create more space between the two of you. You try to climb to your feet, but slip on the tile floor. Aphrodisiakos was one of Moira’s strongest creations: a 98.7% success rate, even when the subjects are only exposed to fumes. Ingesting it increases that rate.

“Okay, relax. What is it?” Genji tries to move closer to you, but you back up again. He stays crouched, like he’s trying to approach a startled animal.

“Genji, you need to leave…” you mutter out, already feeling a warmth building up in your throat. You remember reading about this project. It didn’t take long for aphrodisiakos to start to work. It was mere minutes before it started to impact you, probably Genji too, and you need him away from you.

“I’m not leaving until you at least tell me what it was,” he narrows his eyes, but you can only shudder. Sure, he deserves to know, considering it may have an impact on him as well, but the thought of explaining it has your cheeks flushing.

“It’s…uh…” your throat feels like you swallowed cotton and the smell of walnuts and Genji’s cologne is filling your nose, the scent going straight to your core. “Meant to…increase…sex drive.”

“What?” Genji says, you eventually get your feet under you and stand. Continuing to back away from him, you need to get his scent away from you before you…no, that’s the drug speaking.

“It’s a fuck potion, Genji!” You scream out, your frustration mixing with the project’s chemicals. You keep backing up, him closing every inch of space you try to put in between the two of you.

“Like an aphrodisiac?” He asks.

“A strong one,” you say, your back slamming into the lab table behind you. “You need to leave, now.”

It’s less of a command and more of a plea. You already struggle controlling yourself around Genji as it is, but this is a completely different game now. If he doesn’t leave, you don’t know what will happen.

“Gen-” you call out as he continues to close the distance between the two of you. His dark eyes watch you with an intensity you have never seen from him. His scent fills your nose more as he gets closer, and it’s starting to make you dizzy.

“What if I don’t want to leave?” Genji says once he’s almost touching you. His presence, his scent, the feel of his breath, it’s all too much for your burning skin. You feel like you’re on fire, the heat pooling in your center until you can barely stand. Genji seems to notice the weakening in your knees and he reaches out to wrap his arm around your waist and steady you, but the feeling of him touching you has you melting even more.

“You need to…go,” you can barely get the words out when you feel his fingers drum along your skin. It feels like you have a fever, and sweat starts to bead along your forehead. You look up at Genji, and he stares down at you with glowing eyes.

“Then who would take care of you?” His voice sounds low, and the sound builds the heat under your skin. You might actually explode if you don’t have some relief soon. How the fuck is this so effective?

“I need…something you can’t…” You start to say but your voice falters when Genji’s other hand runs along the back of your thighs and he lifts you into his arms. Your limbs are too weak to fight him and he places you on the lab table.

“I know what you need, baby. Let me help you,” Genji purrs against your neck. You shudder at the sound, at the vibrations from his voice. Your body seems to be picking up on even the smallest things, because it’s all driving you insane. You squirm when you feel Genji’s hand pressing into your inner thigh over your jeans. Any thought about arguing with him dies as soon as his pinky finger ghosts over your clothed core.

“Please,” is all you can manage to say. You hear fabric snap and feel soft lips against the skin on your neck. Your neck falls back as Genji presses rough kisses into it. His tongue slides up along it, and the feeling as your legs clenching together. You need his tongue somewhere else. You feel him smile against your skin as he continues to press kisses there. He eventually pulls back, leveling his eyes with you. His face is maskless, the scars sending heat to your core. Perhaps you shouldn’t be so turned on by his appearance, but it has you dripping for him. You blame it on the drug.

“Just for the record, I would do this without an aphrodisiac,” Genji mutters, then his hand balls in your hair and pushes you against him, your lips crashing together. You moan into his kiss, rough and commanding. His tongue glides along your bottom lip and the motion makes you whimper against him. You try to fight for dominance in the kiss, but when his other hand reaches your hip, you fall apart. All your skin seems to be on fire, his kiss burning you down to your nerve endings.

When he pulls away, his lips are wet and a smile is on them, which reveals a single dimple in his cheek. You don’t have much time to admire him, though, because he drops to his knees in front of you. The lab table puts you at the perfect height for him, and the sight of him on his knees makes you shudder.

“Help me take these off,” Genji’s hands stop at the button of your jeans, “or I cut them off.”

You nod, lifting your hips so he can pull your jeans off easier. Once off, he throws them across the lab, and his mouth is immediately pressed to your inner thighs. You groan out, a soft plea. You need him somewhere else. You feel a metal finger against your waistband, the cold a stark chill to your burning skin. He wraps his finger around the waistband of your underwear and pulls, the fabric ripping easily under his strength.

He pulls the shreds away, leaving your bottom half bare. The cool air of the lab kisses your skin, hot with desire, and it has a shiver running along your spine. His hand reaches your core quickly, his fingers hovering just above it.

“Wanna come on my hands?” Genji moves his face forward, until he is mere inches from your core. “Or on my tongue? Or perhaps my cock?”

You feel the words on your core and it makes you jolt.

“All three? How perfect,” Genji answers his own question, then his fingers are finally on you. It’s his metal hand, which feels cold against your scalding core. Your head falls back as he runs his fingers along your slit, slowly tracing your core. It’s slow, teasing, but you know he won’t have to work very hard for you to orgasm right now.

“You’re so fucking wet for me, baby,” he whispers, placing a soft kiss to your thigh.

“It’s the…” you start, but yelp when you feel a pinch on your thigh. Genji bites down softly on the skin, enough to make it sting but not enough to truly hurt.

“Don’t you dare say it’s the drug. I bet you’ve been plenty wet for me before without it,” he mutters. “I bet you were wet when we kissed the first time, huh?”

“Yes,” you say softly. You want to say more, but a finger pushes into you and any words are replaced by soft mewls.

“It’s okay. I was hard then too,” Genji says against your skin, his finger working in and out of you. He adds another finger easily, and your hands grip onto the edge of the table. His other hand reaches up and finds your clit, moving it in slow circles. A moan escapes your lips, and you flush at how loud it was.

“I knew you’d sound pretty,” Genji says, pushing harder on the circles in your clit. The heat that was on your skin seems to all move to your core, building up like a ticking bomb. Your knuckles tighten around the rim of the desk until they’re white and your arms are shaking. Genji seems to notice, as he picks up his pace. You start to shake harder, your heat building up, until it all explodes. You scream out his name as you come on his fingers, and he continues to work you through it.

You barely catch your breath before his mouth is on your core, his tongue lapping against you.

“Genji!” You scream out, your body still shaking from the first orgasm. You feel his tongue lap one last lick, before he pulls away.

“I told you, three times. That was only on my hands, baby,” he says, looking up at you. His dark eyes are full of promise and his lips are wet with your release. The sight is enough to make your heart flutter and a shot of heat go straight through your body. He seems to know his effect on you, because a cocky smile takes place on his features and he keeps eye contact and he lowers his mouth back to your pussy. His tongue swirls around your clit, and the motion has your head falling back and your hand reaching to his hair. He continues to lap at you, like he’s a starving man devouring dessert.

He builds your orgasm quickly and with expert precision. You’re sure he would be making cocky comments if his mouth wasn’t busy.

“Fuck, Genji, please,” you mutter out, tugging on his soft hair. He growls against your core, plunging his tongue into you and using his finger on your clit. You scream out, your back arching into him.

You continue repeating his name like a manta, a sacred prayer between the two of you, as your second orgasm takes over. It rattles your entire body, your thighs shaking around his head. He uses one of his arms to steady you, but you still shake enough to rattle the table. The orgasm hits as hard as the first one, the heat exploding like a bomb inside you. He continues to lap at your core as you ride out your orgasm. Every drop seems to land on his tongue, and he takes it like it’s the nectar of the gods.

Once you are finally done, he pulls back. His mouth and chin are both wet, and a toothy smile is on his face. He stands and brushes a stray hair out of your face.

“One more. Can you take it?” He asks. The promise makes you shiver, but the heat in your body answers the questions for you.

“I need it,” you plead, reaching forward and fisting his shirt to pull him closer. His smile deepens, that dimple showing up again. You yank at the hem of his shirt and he seems to get the message, pulling his shirt over his head. You reach out to him again, your hands pressing against the soft skin of his stomach. The toned muscles under pale skin flex under your touch, and you dig your nails in slightly. Genji makes a low noise as your nails drag along his skin. He continues to let your hands roam his body as he loosens the strings in his sweats, letting them drop to the ground. The bulge in his boxers catches your attention, and your hand immediately moves to it. As soon as your fingertips barely touch it, Genji pulls in a sharp breath through his teeth. He’s so hard that you can already see the drips of precum darkening his boxers. You give it one stroke through his underwear, and his forehead falls against yours.

“Just the drug?” You tease him, a soft smile on your face. He shakes his head.

“Absolutely not. Part drugs, part you. Mostly you,” Genji admits. Your hand moves slowly, and you can feel Genji’s abs tense as you reach your hand under his underwear band. You dig your nails into his skin before wrapping your hand around his cock. He seems to hold his breath as he waits for your next more. You stroke it slowly, getting used to the way it feels in your hand. He feels big.

“Let me fuck you, please,” Genji says. “I need to be inside you.”

“Please,” is all you respond before Genji is pulling away and ripping your shirt over your head. Your bra gets unsnapped and thrown across the floor somehow, baring your entire body to him.

“So fucking beautiful,” Genji says. He pulls his boxers down and they end up thrown in another clothes pile, and you can finally admire him. You were right, he’s big, and flesh. Your core clenches at the sight of his cock dripping with precum. You need him inside you, now.

He moves back to you, his hands gripping onto your hips. Your legs spread for him, almost of their own accord, before he’s lining up at your entrance. You mutter out another plea, begging for him inside you, and it seems to snap any resolve he had left. He pushes into you, the wetness of your arousal welcoming him easily. The stretch still burns, the sting feeling like its own version of heaven. The room fills with soft breaths and moans he pushes more inches into you.

“Fuck, you feel so fucking good,” he says, as you take every inch of him. You feel so good, so full, but you need more. Genji seems to read you perfectly, because he starts to thrust in and out. It’s slow at first, and it makes you moan each time he pushes in. Even his thrusts are perfect, each motion pushing you further and further to the edge. You whimper his name again, like he’s a prayer on your lips. Maybe he is.

As his thrusts start to pick up, the lab table starts to shake under you. Instruments clatter to the ground, beakers shatter, but you don’t care. All you care about is Genji and the orgasm that is building inside you. His hands on your hips dig in harder and his thrusts start to get sloppy. More heat builds in your core as he pounds into you and you start to whine out. The orgasm builds more, like a star about to explode, until you’re fulfilling his promise. You come around his cock, clenching onto him and screaming out his name. Your nails dig into his back, and the motion is enough to send him the rest of the way over the edge. He moans out your name, then rests his head on your shoulder as his orgasm rocks through his body. His shoulders shake as you feel his come shoot inside you, making you sensitive pussy throb.

He presses soft kisses to your shoulder where he rests as he regains his composure. Once you’ve both caught your breath, he moves away from you. He reaches to grab the glass of water he brought you, that somehow didn’t fall off of the table, and offers it to you. You laugh softly, taking it and taking a sip. The cool liquid feels nice on your throat, and it’s not long before sleepiness starts to seep into your bones. Genji pulls his sweats on and somehow gets your sleepy self to put his shirt on.

“Come on. My room is only a few feet away. You can sleep there,” he says.

“I don’t think I can walk,” you say with a soft laugh, but it’s true. Your legs feel like jelly and you’re fairly certain you’d fall as soon as you tried to stand. Genji smiles back at you, putting his arm against your back and the other one at the bend of your knees, before he lifts you off of the table. As he carries you to his room, you bury your face in his chest. It’s late enough that the halls are empty.

“Wanna know something about aphrodisiakos?” Genji asks.

“Hm?” Is all you respond.

“It only works on people who already had feelings for each other,” he says. You scowl. Now that he mentions it, you do remember reading something like that in Moira’s notes. You smile against his chest as sleep takes over. You have always had feelings for him.
