Tony grunted as he was shoved up against a coarse brick wall, and again when his shirt was forced up and his skin bared to the rough stone. It turned into a moan though when Bruce dropped to his knees and jerked his pants down, exposing hardened flesh and taking it into his mouth in one smooth motion. Tony doubled over at the sensation and couldn't contain the near shout of pleasure when he felt Bruce's throat constrict around him. The kneeling man hummed around him eagerly, using hands and tongue and even slight graze of teeth to make Tony gasp and his eyes roll back in his head. He was so close even from so little attention, lingering adrenaline high from the battle, and nearly dying, making him come to his peak more quickly than he'd care to admit. "Bruce, I'm gonna-" he got out, before nails scraped over his ass and down the back of his thighs, sending him over the edge. His head snapped back, hips canting forward, both hands tangled in peppered hair as he forced himself a far as possible down Bruce's throat, the scientist taking it in stride, even giving his own groan of need.

He was still shaking with aftershocks when he was forcefully turned around, gasping when he felt Bruce spread him and push two fingers inside, slicked solely with saliva, working him open quickly, expertly finding his sweet spot and stroking him until he began to harden again. Then he took his fingers away and was pushing inside in earnest, gripping the other man's hip hard enough to bruise. Tony grit his teeth, breathing shallowly. Under other circumstance he's sure this would hurt too much to be enjoyable, but Bruce doing it made everything feel amazing. He pushed back, meeting the snap of hips, small moans forced out between breaths. A hand entered his line of sight when Bruce braced himself against the wall, bent over Tony's back, small puffs of breath against his skin sending shivers down his spine. "Fuck, Bruce, more," he ground out, gripping onto the arm near his face.

"More what," he gasped with a rough laugh, the first words he'd spoken since dragging Tony out the back door of the shawarma shop.

Tony whimpered like a horny teenager at the sound of his voice. "Everything, harder, faster, more skin." He was cut off by Bruce pulling away a whipping him around. He hefted him up against the wall and hooked an arm under each tight, slamming back inside the squirming genius. Tony clung to him desperately, grinding down, impaling himself even as Bruce pounded roughly into him, taking Tony's request for 'harder' to heart.

He grabbed a handful of curls at the back of his neck, pulling in warning. "Close," he gasped.

"Me too," he answered, hands tightening around Tony's thighs. He came to the feeling of Bruce's teeth sinking into his shoulder, cries out sharply. He writhed and twisted in the scientists hands, scraping his back on the wall to match the rough nail tracks that would be on Bruce's. Sensory overload set in from the feel of panting against his neck hitched, small desperate moans and deep-seated heat inside signaling Bruce's release. The cherry on top was when his knees buckled and he slid to the ground, arms wrapping around Tony and carefully pulling him away from the wall so he wasn't hurt further.

They stayed like that for a moment, wrapped around each other while they caught their breath, until the sound of someone clearing their throat told them they'd been found.

Clint stood about twenty feet away, near the end of the alley. "Not that I disapprove, you two put on a pretty good show actually, but we have work to do." He chucked a grey military blanket at Bruce. "Not to mention Steve's looking for you." Then he turned on his heal and walked away.

They stared after him for a moment, then turned and looked at each other, each waiting for someone to move. Bruce laughed first, then shifted Tony so they could both stand on still shaky legs. He pulled on the tatters of his pants and wrapped the blanket over his shoulders, more to hide the evidence of their actions then for any sort of modesty, and watched while tony redressed as well. They gave each other one last knowing look before turning and wandering side by side out of the alley mouth.

Author's Note: It's probably really shitty. Wrote it in about an hour when I should have been working on something else. Anywho, not necessarily a one shot, depending on the response.
