Tony Stark x Reader Smut

Sticky Sweet Tony x Reader

Bruce's latest concoction has a very unexpected side effect - it enhances taste perception by x100. Tony takes it, with Reader thinking he wants to enjoy some brownies, but Tony has other plans... 18+, Tony's oral fixation, liberal interpretation of science, pleasure dom Tony if you squint. Hot, wet and messy and sponsored by Tony's praise kink. Word count 3k.

A/N: There's a lot of dirty talk :') I wrote this, re-read this and audibly went "hehehe, what the fuck" :') I honestly don't know what hell pits this all came from :') blame the motley crue song with the same title :')

"And what you boys are up to?" Your voice carried over from the lab entrance door, loud and clear, as FRIDAY lowered the volume of the music Tony liked to blast when science took hold of his brain.

Bruce was right next to your boyfriend, shirt stained with tea and curls bouncing in tune with Mötley Crüe's very own Tommy Lee banging on the drums. It took him a while to get used to Tony and his tendency to be loud, but now, years in, the two science bros were practically inseparable.

You and the girls often shared a laugh at the way the duo acted so much alike like two high school girl best friends, even going as far as to share each other's clothes. For their scientific ventures, unfortunately, it made all common sense to fly out of the window. Explosions galored, semi-sentient sludge was made (and almost escaped, melting the heavy-duty security doors) and Steve was annoyed red, white and blue with two grown men acting like giddy children.

It made all the sense that you, Tony's girlfriend, were often sent on recon missions to make sure the science bros haven't accidentally offed themselves or caused an apocalypse.

"Nothing particularly successful," Tony's frustrated grumble and subsequent pout had you leaning into his space to give him a quick peck on the cheek. The man rewarded you with a brief squeeze of your hip, the hand trailing down to squeeze your ass. "We thought we made a chemical to detect and neutralize sedatives, turns out all it did was make coffee taste really, really bitter."

You chuckled, sticking your own hand down the back pocket of his jeans. "Ah, yes. Crimes against coffee are crimes against humanity."

Tony nodded solemnly, not taking his eyes off his holograms. "Absolutely. There is no Iron Man without coffee and there is no world peace without Iron Man." He stated seriously, the corners of his mouth twitching.

Bruce remained quiet, the cracks of a reluctant smile threatening to appear on his focused face.

You studied the floating holograms, documenting the shape and placement of the molecules. Truth to be told, you understood maybe 1/10 of what was displayed on the screen, but after spending so much time around geniuses, you had come to a conclusion that even a small, silly question could get their brains going.

"That's all it does? Makes food bitter?" You asked innocently.

"Well, no," Bruce immediately perked up, pushing his glasses back onto his nose. "It enhances taste perception by activating some neural pathways in the brain that aren't commonly used."

You mulled over the thought, suddenly struck with a brilliant idea. "Well, damn. You make me want to try it. We've got some chocolate fudge brownies Wanda made in the morning, upstairs." Perking up, you squeezed Tony's butt, before adding thoughtfully. "If Thor hasn't found the second stash yet. I swear, he'll eat us out of the house one day..."

Both Tony and Bruce froze, lifting their eyes from their science project and sharing a look. Most of the time, it was a Look™ that preceded at least one explosion and a haste trip to medical, but this time, you felt nothing but amusement at two big-brained dorks missing out on the most obvious upside of their failed experiment.
