Hands - DKBK

Say it with me now Izuku's Hands <3

Katsuki had always been enamoured by Izuku's hands, be it on his body or on any other surface really. He adores them. How they look, feel, or even how they work. Izuku's hands may get muscle spasms and be a bit crooked at the fingers from years of hero work but god.. they were magnificent.

Izuku had hands sculpted from the gods.

Big and thick fingered, large and calloused at the palms and thick in the wrist. His hands were a work of art, knuckles knobbed and full; perhaps bruised if it'd been after a vigorous day of work or training. Veins like lyre strings, in hues of blue or lilac, indenting beneath his skin when he curled his hand into a fist or his wrist turned a certain way. The skin tanned, with bits of scattered freckles or scars that were striped like that of a tiger, twitching with muscle spasms or rigid to the touch.

And, god, could he work those hands like magic. From lifting things, breaking things, hell even fucking making things got Katsuki so fucking worked up it was downright sinful. He loved watching those fingers tug at fabric, or curl around the ends of the table he leaned against.

His hands were strong too. Power coursed beneath every tendon, every padded muscle in his palm and curved line of his fingers. Katsuki could often see green lightning flash across his arms all the way down to his fingertips. But even without his quirk, he could easily lift him like he weighed nothing.

And Katsuki loved when he did. Loved when Izuku lifted him like he were weightless, slamming him down against whatever surface he could and instructing him, downright ordering him to open his legs. With those hands on his body Katsuki would do anything. He was weak to those hands and he knew it, but who could blame him when they traced so delicately over his inner thighs or held tight and possessive at his waist. Or held his own hands and massaged the sensitive palms so delicately one would forget he had the power to destroy buildings with his bare fists.

After learning how Katsuki loved his hands, adored feeling them on his body, Izuku started having a new fixation. He'd always been a service top, even when fully dominating his partner, so he wasn't the type to deprive Katsuki of much, especially when he liked what Katsuki wanted.

He'd began to fuck him with his hands as much as he could.

Like when watching a movie, slowly stroking Katsuki's dick so featherlight it couldn't be more than a graze, rewarding him by fully grasping his length in the heavy cusp of his palm and squeezing him through his orgasm.

Or like now, forcing him to sit still as he ran over notes in his office while he sat in his lap, throbbing around the two fingers buried deep into his ass. Similar to cockwarming, except all the more tortuous when coupled with the fact Katsuki knew how skilled this man could be with just those fingers alone, but just now making him wish he were more full. Full with his cock which was just as thick, like a goddamned coke can, hung so heavily Katsuki wondered how his boxers didn't tear.

"Zuku, please.." Katsuki rasped, his knuckles turning white as he held so tightly at the armrest of the office chair, narrow hips desperate to roll and gain friction if it weren't for Izuku's other hand bearing bruises into his pale skin as he held him down. His own hands shook as he held the paper Izuku was reading.

"Hold still." He murmured as his eyes tracked the shaky script beneath the golden, thinly wired rims of his gold tinted glasses. He didn't look up from the passage he was reading as his fingers twitched, tendons flexing as his knuckles tensed beneath the tight ring of Katsuki's hole desperately sucking him in.

"Y-yes sir." He'd lost track of time, despite how often his eyes shifted to the clock to try and measure the extent of torture he was going through. Izuku was still fully dressed, for fucks sake, his stupid suit tight against his broad chest and beefy shoulders, tightening around his bicep each time he flexed or moved, hell even breathed. His thighs trembled around Izuku's forearm as he felt him move again as he mumbled to the script.

"Interesting, the organization doesn't seem all too organized. Their boss seems to-" Izuku's words turned into a quiet buzz when his crooked fingers tilted against the bundle of nerves they'd been grazing for the past half hour and Katsuki whimpered, squeezing his legs around his forearm. A slow, pulsating effect worked over Izuku's fingers from full cowling as he let his quirk roam. Black Whip curled around Katsuki's hips to keep him in place as Izuku's other hand moved up his waist, pressing flat against his stomach to pull him down further against his lap until Katsuki's back arched against his chest.

His fingers worked in and out, a slow thrust that had his hole twitching and fluttering to keep him in as he rubbed circles inside of him and spread his fingers to force a slow, burning stretch. "Mmn.. Izu- Izuku~"

"Shh, Kacchan." Izuku whispered in his ear. "Almost done now, darling, don't ruin your reward."

Katsuki whined as he muffled his groan by biting into his bottom lip, which had slowly turned red beneath the abuse. He felt black whip loosen a bit and his hips rolled, a blessed friction finally running up his body and shooting straight to the base of his dick as he gasped in relief. Izuku began to work his fingers again, his thumb pressing to the side of his ass, squeezing against his cheek as his middle and ring finger rubbed back and forth faster and harder so Katsuki was forced into a constant rocking to satisfy his ache. He could feel the cold metal of his ring each time he bottomed out against his hand, ass slapping against his palm as quiet, muffled moans left his swollen, bitten lips.

Izuku had no mercy. He would fuck Katsuki on his fingers until he was a shaking, blathering mess, stringing out multiple orgasms, before pushing him up against his desk, shoving his papers aside and making love to him against it, pinning him down and bruising his wrists beneath his wanted touch.
