Side Effects | Bruce Banner x reader

summary: you never know what might be in the beakers at another chemist's station. you never know which of your colleagues might come along just in the knick of time to become the only antidote to your affliction.

word count: 3.6k

warnings: smut! (dub con due to sex pollen), semi-public sex (because technically someone could have walked by but unlikely), guilt/hesitance, kinda pining??, fingering, creampie,

a/n: yes, this is an accurate depiction of emergency shower protocol in a chemical lab and yes it is every lab technician's worst nightmare. thankfully the other stuff is not an accurate depiction of any known chemical, lol.

You wiped your forehead with a tired sigh, staring down at the calculations in front of you before using your pen to scribble over them before tearing out the page and throwing it away.

“You still do that by hand?” Bruce interjected, making you look up at where he was leaning in the doorway to the lab, watching you work.

“Oh, Dr. Banner!” you greeted with a smile, wondering if it was too ecstatic. You weren’t so good at the ‘playing it cool’ thing like he seemed to be.

“We have all those fancy screens and digital whiteboards, you know,” he explained as he stepped in and looked around at your work. “Not to mention the computer can do that stuff for you.”

“I know,” you scoffed, “but I always feel better doing it myself, on real paper. Not that I’m having any luck at the moment…”

"Here, I'll give them a quick look while you take a break," he offered, glancing at the numbers from over your shoulder. "You just get up and stretch your legs for a minute, doc."

You always thought it was sort of silly for him to call you that when he was a doctor as well, but you didn't complain.

Regardless, you were about to tell him that it was fine and you didn't need a break, but he was leaning in closer to take your seat and the proximity was so intimidating that you hopped up and went along with it anyways. He sat down and pondered your calculations while you circled the lab, taking a moment to appreciate how nice it felt to stand up and move around after sitting for so long.

"Your handwriting is…" Bruce trailed off, adjusting his glasses.

"Feminine and graceful?" you finished sarcastically.

"Sure," he chuckled.

"Yeah, just like me—" you started to quip, but mid-sentence you (ironically) stumbled and tripped, using a nearby table to catch yourself— but you accidentally grabbed onto a beaker, which tipped over and smashed onto the ground. The liquid inside spilled onto the floor just before you did, and you winced as you fell into the puddle of the unknown substance.

“Shit!” you hissed as you scrambled to get up, looking down at your clothes and seeing they were covered in the fluid, which was beginning to evaporate, or steam, or something. Remembering lab safety protocols, you instantly began to strip, closing your eyes and wishing Bruce hadn’t come in just before this. As you shirked your lab coat, shirt, and skirt, you walked to the emergency shower, pulling the lever and gasping when the chilly stream of water poured down on you. Bruce looked at you with wide eyes before being kind enough to turn around as you shivered and removed your bra and underwear, now completely naked and weakly scrubbing yourself with your hands in hopes that none of the chemical had gotten onto your skin.

“What is it?” he asked nervously, turning his head back enough that you could hear him over the flow of water, but hopefully not so much that he could see anything important.

“I don’t know,” you answered, “it’s not mine. It’s something Dr. Sutherland was working on…”

“Is it… are you in pain at all?” he asked, even more concerned, and you tried to decide if you could feel any effects.

“N-no…” you answered hesitantly. You felt hot, and strange, and you were covered in rolling chills, but you figured that was just the situation you were in— naked in a tepid shower in front of your coworker who just so happened to be incredibly sexy.

“I should call poison control,” Bruce offered as he reached for his cell phone.

“No, I’m fine,” you denied as the water flow slowed down and you wiped your face, confident that you looked like a complete mess— but at least you saved yourself from whatever was in that beaker, right?

“Here,” Bruce offered an emergency blanket to you after pulling it off a nearby shelf, and it was not at all absorbent but it helped with the draft as you stepped away from the shower which was still leaking the last few drops of water onto the drain on the floor.

“Thank you,” you nodded nervously, shivering and dripping and looking back at him with no idea what to say at all.

“Do you feel alright? I should check you for burns,” he suggested. “I— I won’t look…”

“Please,” you sighed, pulling the blanket a bit to expose your chest and stomach. He brushed his hand over the skin there, making you instantly whine as heat burned just under your skin, clouding your mind and making you crave even more.

"Did that hurt?" he asked anxiously, pulling away, but you stepped closer.

"No it's… it's good, it's so good."

He furrowed his brow as he looked down at you, putting the back of his hand to your forehead. "You're burning up, doc, you must be running a fever of 105."

"Touch me more, please," you whimpered. It was like you were in a dream, everything foggy and distant, and the only time that anything made sense was when he touched you. Or maybe it was that his touch sent you further into delirium; you couldn't be sure.

He gasped when he looked at your quivering legs only to find slick arousal running down the inside of them, threatening to drip onto the floor.

"Oh," he sighed.

"Please," you begged mindlessly, "Dr. Banner, I n-need you…"

"No, you need medical attention."

You whined and grabbed as his shirt, humming at the feeling of his warm skin just beneath. If the forearms that he often left exposed in rolled-up sleeves were anything to go buy, his chest was probably toned and tanned, lightly dusted with dark hair… you were all but drooling at the thought. "Please, Bruce… just help me," you pleaded, looking up into his eyes which were swirling with conflict.

"I can't," he shook his head. "I'd be taking advantage."

He must have seen the heartbreak of rejection make you wince, because he tried to soothe you with his hands resting on your arms— even just that contact making you suppress a moan.

"I've wanted this for so long," he explained, "and you— you haven't. You're unwell, you need to go to a hospital."

You sobbed a little at the idea of being taken away from him and examined by strangers, when you knew the solution was right in front of you. "No, no Bruce they'll touch me! Nobody can touch me but you, I only want you."

He scoffed, but you heard the weakness in it and you needed him to give in soon before you melted from your own hear. "You're deranged— delirious," he reiterated.

"It'll feel so good, please Bruce, I'll be so good for you— anything you want, I'll do it, I'm yours."

"Stop talking like that," he winced. "I can't… I can't."

"I need to feel you inside me, Dr. Banner, I need it more than anything. It's just gonna get worse… please, help me. I want you. I trust you."

"You'll hate me in the morning," he asserted. "God, this is so wrong…"

But much to your relief, he reached down and hesitantly slid his thick middle finger through your folds, gasping gently as he felt how wet you were. "I should t-take you somewhere private."

"No, need you now— right here," you pleaded, trying to chase his touch with your hips.

"But if someone came by—" he began to fret, glancing at the door; but his attention was turned back to you by your hands weaving into his hair.

"Nobody else stays this late, god, Bruce please I just need you so bad—"

He cut you off with a sudden kiss, which was enough on its own to make warmth bloom in your gut, but then he started to move his finger again and you shuddered with a moan that was muffled by his lips.

"Maybe I can make you come like this," he offered as he pulled back just enough to whisper to you, "would that help you? It'll take the edge off."

You bucked and moaned against his fingers, just those subtle touches driving you wild. "N-no, it has to be inside! You have to fuck me, I need your cock."

He breathed through his teeth, like he was almost considering it, but then looked away. "I can't," he shook his head.

"Can't or won't?"

He frowned. "Won't. I'll get you off with my fingers, otherwise it would be… too selfish."

"Bruce, I'm literally begging you for it," you sighed, the irritated tone that you'd intended lost in the moans he elicited by rubbing your swollen clit.

"I know," he winced, "I know and it's killing me that I can't give you what you're asking for… I swear if it wasn't like this…" he trailed off as you looked up at him with your bottom lip between your teeth.

"What would it be like?" you asked lowly. "Tell me how you would fuck me."

For all his shyness before, there was a brief switch in his demeanor as he leaned in, breath hot against your neck as he whispered, two fingers sliding into your channel at the exact moment that he spoke.

"So fucking hard."

You whimpered, knees wobbling a bit as you tried to ride his fingers— but he wasn't pushing back, wasn't giving you enough force to balance against when you sought more friction. "P-please, Bruce— I know you want to, please, please baby I need it so bad…"

"I know," he breathed, free hand cradling your face as his thumb stroked your cheek, and it was so needlessly compassionate, so effortlessly soothing that your heart had no choice but to clench at his tenderness. Other parts of you clenched as well, in much more literal ways, but the heart thing was more important.

You gingerly reached forward and palmed his cock through his pants, moaning when you felt how hard it was. "You're desperate, too," you informed him with a little smile. "It hurts, doesn't it? It aches."

"Yes," he answered tensely.

"I'm hurting too. I'm aching, for you. Please, Bruce, help me."

As he pulled back and examined your face, he chewed his lip and contemplated. He couldn't stand to see you in pain, but he couldn't comprehend what he had to do to help you. Well, okay, that's not totally accurate because he had actually "comprehended" the idea of making love to you plenty of times. But that was just a fantasy, a very misguided one that he only indulged in in his weakest moments. And in those fantasies, shockingly enough, you were always completed lucid and of sound mind and body. He sadly could not say that for you at the moment, and of course he couldn't because of course when you were sober and healthy, you didn't see him that way.

Bruce prided himself on his logic, his integrity, his patience. Suddenly, those qualities were falling prey to a much deeper, carnal instinct that saw this not as a predicament but as an opportunity. Logic states, after all, that it would be wasteful to have everything he wanted thrown into his lap and to let it go to waste.

"Fuck," he groaned as he kissed you again, fucking you faster with his fingers. You moaned and went for his belt, barely managing to open it with your hands shaking so much; part of you had considered just trying to rip the leather off of him, and with the force of your need it seemed almost plausible.

Finally getting his trousers opened just enough to reach inside, you purred as you reached in and navigated past his boxers to wrap your fingers around his hard cock. It was so thick and smooth and hot and you almost wanted to drop to your knees and take it in your throat right then, but you had better plans.

He pulled his fingers out of you slowly, grinning against you at the way you whined, before wrapping his arms around you and quickly instructing you to jump.

It was infuriating, how easily he caught you when you wrapped your body around him. Infuriating and so painfully sexy.

He never broke the kiss as he walked the two of you to your lab table, sliding the papers aside and onto the floor to set you on it. You started on his aggravatingly-small shirt buttons while he pushed his trousers and boxers down the rest of the way, and god his cock was right there between your legs, so close but very much too far away for your liking.

You didn't have the time or energy to get his shirt off, settling for just running your hands over the exposed skin instead. He grinned and watched the path your hands made, hissing slightly when they wrapped around his shaft— for a second you swore you could feel it throb.

"Don't make me wait anymore," you whispered your plea, sighing a little when he nodded.

"Okay baby," he agreed.

"Been waiting so long," you whined.

"Me too," he nodded, and with a little push, his cock slid all the way into you and filles you to the brim. Even when you were completely drenched, the girth of him was so wide that it stung, that it tore you open, but you loved it. Your head fell back and just from him being inside you, you came. The substance had you so needy and sensitive that that was all it took. It wasn't enough yet, of course. You knew you needed more. But God, he felt so good you could hardly breathe.

"Baby," you heard Bruce gasp, his fingers digging into your hips. Your chest twisted when he laughed a little, breathless and just teetering on the line between complimentary and mocking. "Did you just come?"

You considered playing dumb, but nodded instead.

His smile was apparent when he pressed his lips just below your ear to suck on the delicate skin there, his teeth trailing up to nibble your earlobe lightly. You hoped he would leave a mark, you hoped he would leave lots of marks that you could remember this by for weeks to come.

"Couldn't help yourself, huh?" he asked breathlessly, whispering so quietly you could barely hear it over the beating of your own pulse which echoed in your ears.

"You feel so good," you justified, "so fucking good, Bruce."

"You too," he sighed as he finally pulled back and slid into you again, the friction making your back arch instantly. "Even better than I imagined."

You smiled and wrapped your legs around his hips, forcing him to push deeper with each thrust. When he pushed you to your limits it felt like you might just fall apart right there, but it was so worth it.

As if that wasn't enough, he reached down and circled a thumb over your overstimulated clit, grinning down at you at the sight of you writhing and bucking wildly in his arms.

"Fuck!" you cried as you tightened your hands on his shoulders into fists hard enough to risk tearing through his shirt.

"Too much?"

"More," you pleaded instead, crying out when he gave you exactly what you wanted with fast, rough thrusts into your drenched walls. "Yes," you sobbed, "yes, fuck— m'gonna come, Bruce, gonna come again."

"Go ahead," he encouraged, voice so much rougher than normal, "show me how good it feels, baby."

It felt like his words were the thin that pushed you over the edge, as if your body somehow both understood and obeyed his command. You could feel a renewed wave of slick leak out from you, enough that you could hear the wetness in each slap of his hips against yours. His name was somewhere in the litany of curses and praises that spilled from your lips, your mind too clouded with hazy pleasure to keep track of what you were actually saying.

"Just like that," he groaned, "doing so good, fuck, say my name just like that every time I make you come."

An easy enough stricture to follow, especially when it seemed like he was all you could think about. He looked so different with his clothes half-shorn and his eyes dark with lust. He hadn't taken his glasses or labcoat off and you weren't sure which of those you were happier about.

His lips and hands were all over you; you couldn't even keep track of everywhere he was touching you, that's how overwhelming it was. "God, you're so fucking perfect," he groaned against your skin, finding a hardened nipple as his tongue explored you and wrapping his lips around it. "You are so goddamn sexy, you know that? I love seeing you with your legs spread for me like a needy little whore. I love hearing you moan and knowing I'm the one making you feel this good."

He took a moment to look at you and soak in your shocked reaction to his words before leaning in to continue.

"I love feeling you come for me," he purred in your ear.

"Then you're gonna really like what I'm about to do," you shivered.

"Yeah? You can gimme another one already?" he smiled. "Such a good girl…"

You really couldn't help it, it felt like everything he did only enhanced your pleasure— his words, his hands all over you, not to even mention his cock inside you. As much as the hedonistic corner of your brain was happy to let this go on forever, the ramifications of constant orgasms were finally catching up with you as you wondered how much more of this you could take.

"F-fuck, are you close?" you asked weakly. "Want you to come for me, Bruce, please."

"I-I'll pull out," he suggested, although the way he looked down at his length sinking into you and pulling back out, covered in your abundant arousal, didn't exactly indicate that he was willing and able to actually make good on his offer.

"No!" you yelped, pulling him closer by his unbuttoned shirt. "It needs to be inside, Bruce, please come inside me."

"Fuck," he hissed through his teeth.

"Please, Bruce, please, promise you'll come inside."

"I will," he sighed, "fuck, I will baby, I promise I'm gonna fill you up so good, you're gonna have my come so fucking deep inside you…"

"Yes!" you moaned, completely unabashed as the unknown substance had apparently absolved you of any shame whatsoever. "Yes, I want it, Bruce, I want your come."

The moment you felt his seed start to paint your walls, you felt relief begin to wash over you. Your mind and body relaxed, the overwhelming heat under your skin subsiding into a comforting warmth, the desperation that had burned in your gut satiated at last.

And that left you staring up at him in realization of what you had done, just as he looked back at you with the same.

"God, I'm so sorry—" he shuddered, moving to pull away. Instinctively your legs wrapped around his hips again, holding him close.

"N-no, wait," you groaned, "it's okay. Don't go."

"You don't hate me," he said, the exhaustion in his tone making it hard to tell if it was a question or a statement.

"Never," you sighed with a weak smile, sitting up to clutch his face and kiss him again. "God, Bruce, now I'm just wondering what took us so long."

"Our lab safety is just too good, clearly," he smiled as he kissed you again, pulling back a little too soon to examine your face where he held it in his hands. "Are you okay? You should still probably go to a doctor…"

"I'm already with a doctor," you smirked, "and his treatment was very effective."

"Yeah, that was…" he trailed off, wide eyes as if he were reminiscing about what had only just transpired.

"Sorry for being so… desperate," you cringed. "I didn't mean to… um… impose…"

He just laughed and kissed your forehead, making you feel your cheeks warm a bit; ironic that with everything that had just happened, this was what made you blush. "A beautiful, amazing woman that I've been dreaming about for months begs me to take her in the laboratory… really inconvenient."

"I mean, cleaning up these papers and the broken glass is gonna be pretty tedious, along with the incident report," you frowned.

"I'll help you with it," he offered.

"Tomorrow," you decided. "Right now, I'm taking you to my place."

"Is that so?" he asked with a bemused smirk.

"Yep. We both are in serious need of a shower, and then I wanna go again," you grinned wickedly.

"I thought you said you weren't feeling the effects of the chemical anymore," he recalled, voice tinted with concern.

"I'm not," you reassured, "I'm just feeling the effects of you."
