I just sent ask with Bruce Banner and smut but I didn't do anonymous so please ignore that lol
I’m answering the anon one you sent; no worries, sweetie! This was accidentally sort of a longer one too lol I keep getting carried away.
(Obvious) warning: smut
Bruce was normally so careful with you when it came to sex; gentle caresses, sweet kisses, whispered ‘I love yous’ in the darkness that night offered. He was always nervous about things getting too out of hand, about hurting you, no matter how often you reassured him that you weren’t scared of the other guy. You knew your boyfriend had the control he needed to keep himself in check, but Bruce wasn’t so sure. So, for the time being, your sex life was like a slow burn, full of passion and love. Sure, it was a little repetitive (and if you were being honest with yourself, maybe you craved something more), but it was never boring and you were always satisfied.
That’s why you were so taken by surprise when Bruce wordlessly led you out of the lab today, turning a few corners through the hallways before dragging you inside a janitor’s closet. He calmly flipped the lights on and locked the door, then turned back towards you, his eyes gleaming in a way that had nothing to do with the other guy. He leaned back against the door, his hands behind his back as he looked you over from a few feet away.
“That skirt is rather short, Y/N,” he said, his voice hoarse and dripping with lust. You fidgeted, subconsciously tugging it down to cover a little more of your thighs. His eyes followed your movements, and you watched his tongue dart out, swiping over his bottom lip.
“I just bought it yesterday. I thought you’d like it,” you told him. He breathed in deeply through his nose, letting it out of his mouth noisily before he answered you.
“I do.” The two of you were silent for a moment, and then suddenly he was right in front of you, his hands roaming your body as he attacked your mouth with his. He turned you around, walking your backwards until your back hit the door. Bruce pulled away from you long enough to touch two fingers to your mouth, tapping at your lips until your opened for him. You used your tongue to wet his fingers, gasping as his other hand hiked your skirt up to your stomach. His fingers left your mouth, drifting down to the hem of your panties, pulling the thin piece of fabric down your thighs.
“Guess I should wear this skirt more–” Your sentence cut off, your breath hitching when Bruce wasted no time pushing a finger into your wet entrance, pumping in and out twice before adding the second. Your forehead fell to rest against his chest, your hands bracing on his shoulders. “Often,” you finished saying as you panted against him, moving your hips in time with his hand. Bruce’s free hand came up to touch the side of your face, tipping your head up to hungrily capture your lips again, swallowing your moans of pleasure.
“You have to be quiet, baby,” he mumbled against your mouth, shushing you as you cried out when his fingers caressed your sweet spot. A high-pitched whine clawed its way out of your throat as you felt your orgasm approaching, the heat in your stomach coiling deliciously. Suddenly, Bruce’s movements stopped, withdrawing his hand from you mere seconds before you would have reached your climax. You immediately pouted, your head falling back against the door as you glared at him. You opened your mouth to complain, but stopped when he put a finger against his lips, indicated for you to be quiet.
“Stark! Have you seen Banner anywhere? I checked the lab for him, but I can’t find him.” You jumped slightly as Steve’s voice came from the hallway, seemingly right from the other side of the door you were leaning against.
“Haven’t seen him, Cap. He’s probably off with Y/N somewhere. She was dressed to kill today,” Tony responded dryly from nearby, the two of them laughing together. Two sets of footsteps walked down the hallway, further away from where you and Bruce hid. When you were sure they were gone, you burst into laughter.
“That was close,” Bruce said, popping his fingers in his mouth to clean your juices off of him. Your laughter faded, desire flowing through you again. Bruce smiled, lust filling his eyes as he leaned into you, peppering kisses up your neck and jawline until he reached your ear. “We’ll continue this later,” he whispered, pulling your panties back into their proper place and tugging your skirt back down. He unlocked the door, flipped the lights off, and pulled you out of the way so that he could exit the room, leaving you alone, high-strung and tense, and so looking forward to ‘later.’
