#MHAKinkmas2022 Day 3: Body Worship - #bkdk 🔞 dekussy, body dysmorphia, mildly possessive bk, emotional hurt/comfort

There were days where Izuku felt like he wasn’t deserving of much, let alone the pure adoration and love Katsuki showered him with on a near daily basis.

He often fell into a self-deprecating trap, where one comment from the media or online or even just a glance in the mirror sent him spiraling. He was plain, his face a mess of freckles, his skin marred by scars, body a ragged field of mistakes.

He rarely loved the body he was in, and most days he could get away without thinking too much about it.

But on the worst days? On those days, Izuku became a shell of himself, drowning in old and oversized shirts and sweats, doing everything in his power to stay inside if he didn’t have patrol.

He would roll himself up in a blanket, or stay in bed far longer than he really should, hiding in the dark.

Those days, his eyes took on a glazed and far-off look and on more than one occasion, he’d find himself picking at scars until bits of skin peeled off and he’d bleed.

Since moving in with Katsuki, though, those days were getting harder and harder to hide. Katsuki was, as he tended to be, perfectly observant. So he saw the signs before Izuku did, noticed when Izuku started to curl into himself, when he needed a little push towards some loving.

“I want you to wear this for me,” Katsuki rumbled, hands curling around Izuku’s waist, thumbs rubbing circles into the pliant flesh there.

Izuku squirmed, but Katsuki didn’t relent. He dipped his hands under the hem of Izuku’s ratty old sleep shirt (a white tee that said ‘Awake’ in large letters) to run his hot palms up his sides. He felt his skin buzz with Katsuki’s touch.

“Kacchan…” Izuku mumbled. “I don’t–”

“I know, baby,” Katsuki murmured into Izuku’s neck. “But will you do this for me? You can always use your safeword.”

Izuku chewed his bottom lip, staring at the outfit Katsuki had laid out on the bed. It was something Izuku had worn before, on good days, plus a little something extra.

A soft gray-brown crop top with exposed shoulders, a black flared skirt with the signature Dynamight burnt orange cross at the side, and a pair of black and orange lace panties.

But today was not a good day, and he hesitated.

Katsuki wasn’t trying to humiliate him, was he? No, that wasn’t Katsuki’s style, not when he knew it was a bad day for Izuku’s self-image. The soft, gentle kisses the blonde trailed along Izuku’s neck were all he needed to know that Katsuki knew what was going on in Izuku’s head.

“You trust me, ‘Zu?” Katsuki murmured, wrapping his arms languidly around Izuku’s hips.

“Of course,” Izuku said softly. There was no doubt about that. He loved and trusted his boyfriend with everything and anything.

“Do this for me, and I promise, I’ll make you feel good.”

Izuku hummed, relenting. “Okay.”

“Thank you, baby.” Katsuki squeezed him tightly around his waist and pressed a kiss just under his ear, his breath tickling. “Go change in the bathroom, I’ll get everything else ready.”

“Everything?” Izuku echoed. What was there to get ready?

“You’ll see, it’s a surprise.” Katsuki purred, and Izuku could feel the smirk against his skin.

Izuku gathered up the outfit and retreated to the bathroom, keeping his back to the mirror as he changed out his sweats and t-shirt for the new garments.

He felt like too much packaged into a tiny casing, chunks of flesh spilling over the fabric, like his pudgy stomach hung gracelessly over the skirt, his legs and knees looked ruddy and strange. He felt the lace itch and dig into his sensitive skin.

Izuku feared catching sight of himself in the mirror before he left. He didn’t want to know what he looked like; the mirror usually confirmed his worst fears, that he looked as awful as he felt.

So Izuku flicked the light switch and stumbled back out of the bathroom in the dark.

When Izuku returned to the bedroom, he found the lights dimmed and muted, the bed sheets pulled and spread into what he could only describe as a nest, and a series of fancy, silken pillows piled on top.

“Kacchan?” Izuku called.

His boyfriend emerged from their closet, shirt mysteriously missing, sporting his favorite Deku branded gray and green sweats. A little thrill hummed through Izuku’s heart. He loved seeing Katsuki in his colors, just as much as Katsuki loved seeing him in Dynamight colors.

Katsuki’s smile was warm and soft when he saw Izuku, hand automatically reaching out to thumb at the dip of his hips just above the skirt. His other hand trailed over his jaw, cupping his cheek. The gentle heat smoldering in Katsuki’s carmine eyes set Izuku’s guts aflame.

He felt the fire coiling in his belly, the panties immediately soaking in a patch of slick arousal.

“Mm, baby, you look so good.” Katsuki murmured, dipping his head down into Izuku’s neck to mouth at the exposed skin of his collarbone. “You’re beautiful.”

Izuku grumbled noncommittally, casting his gaze away.

“You don’t believe me, ‘Zu?” Katsuki pulled back to look at him with a perked brow. “Let me convince you then.”

Before Izuku could say a word, Katsuki dipped down to scoop him up into his arms in a princess carry. Izuku buried his face in Katsuki’s broad chest, hiding his flush, and wrapped his arms around his neck.

He felt too heavy to hold, like his bones were made of lead, dragging Katsuki down.

But Katsuki was a pro hero, with the body build to back it up. His shoulders were massive, his arms corded thick with muscles. His abs were legendary. Izuku felt like he barely compared, and he was the one with the stockpiled strength quirk.

Katsuki lifted him as if he weighed nothing, carried him to the bed and placed him gently on the silken pillows.

The blonde nuzzled Izuku’s cheeks, nosing at his freckles, kissing each little dot, littering pecks across his entire face. Izuku flushed bright red, trying to wriggle out of Katsuki’s reach, but his boyfriend gently cupped his face with hot hands and pulled back to lock eyes.

“You’re amazing, Deku,” Katsuki murmured, each word stern and steady, “You’re beautiful. Every inch of you. All the things you think should be hated, I love. +

I love your freckles,” he plants a kiss along the strongest spattering of them on his face, “your face,” he presses a little kiss to the tip of his nose, the corner of his eye, his forehead, “all of you, scars too.”

Katsuki traveled down Izuku’s body, lips trailing over each bump and scar he’d accumulated over the years. Pressing hot lips to the edges of old faded things and fresher healing wounds.

He tongued at his collarbone, nipped at his exposed shoulder, hands traveling down his sides to rest at his hips. Katsuki pressed kiss after kiss to Izuku’s heated skin as he made his way down his navel, leaving tiny bite marks at his hips.

“I want to leave my mark on every inch of you,” Katsuki said, leaving a particularly sharp bite just above the skirt’s hem. Izuku bucked his hips, biting back a groan.

“There are days I can’t believe you’re mine.” Katsuki looked up from where his face rested against Izuku’s thigh, catching his watery green gaze. Red burned into green with a deep, dark hunger.

His voice turned quiet, reverent. “There are days I want to keep you in this room, just for myself. I want to fill my every moment with you.”

Izuku’s lip trembled. “Kacchan…”

“I want to be all you think about, all you need.” Katsuki pressed a hot kiss to Izuku’s thigh, nose pushing the bottom of the skirt to the side. “I want to be your everything, baby.”

Izuku couldn’t keep the tears from spilling. He sniffled and immediately Katsuki was leaning over him, one hand carding through his messy green curls and the other tilting his face by his chin. He kissed the tears trailing down his face, tongue lapping up the salty trails.

“I want to give you everything. You deserve the world, Izuku. You are everything to me, you know. My life is better because of you, I’m better because of you.”

Katsuki pressed a firm kiss to Izuku’s lips, gentle and loving. Izuku tried to deepen the kiss, feeling that urgent fire spreading through his limbs. But Katsuki kept his slow pace.

It was tortuous in that Izuku wanted more but also so overwhelming with how much love each touch of their lips sang with love and admiration. Each touch of their skin sent crackles of lightning through them both.

“Stay right there,” Katsuki whispered the order, brushing his thumb along Izuku’s cheek.

Katsuki dipped back down, nails trailing over Izuku’s exposed skin, one hand reaching under the crop top to tease his nipples, the other hiking the skirt up to drag teasing fingers along Izuku’s pussy.

Izuku squirmed at the sudden feel of calloused fingers rubbing at his lower lips, thumb finding his clit and pressing into it through the panties.

“Fuck, you’re so gorgeous,” Katsuki hissed, biting into Izuku’s milky thighs. “M’gonna eat you out, baby. Wanna drink your cum.”

Izuku moaned and nodded frantically, unsure if Katsuki was even looking at him at that moment. The fingers working Izuku’s nipples disappeared before he felt them grip his hips, raising him just slightly above the pillows.

Both legs were positioned over Katsuki’s shoulders, thighs pressing tight around his neck. Katsuki groaned as Izuku’s thick thighs squeezed.

Katsuki pushed the edge of the lace panties aside, just enough to reveal Izuku’s puffy cunt lips, the soft green curls poking out from beneath the fabric. He dragged his tongue across Izuku’s heat, flicking at his clit.

Izuku moaned, low and deep, and squirmed lower to plant his pussy deeper on Katsuki’s face. The blonde rumbled into Izuku’s leaking sex appreciatively before working him open with his tongue, sucking occasionally on his clit, leaving him throbbing and wanting.

A finger slipped in between thrusting licks, spreading Izuku wide. The blonde pushed two, three fingers in, twisting his wrist and tongue fucking him with abandon.

Izuku felt searing heat on his labia and he just knew Katsuki had activated his quirk, not enough to explode, but more than enough to spread fire through Izuku’s entire body.

“Cl-close, Kacchan!” Izuku panted, “I’m g-gonna…”

Katsuki smirked, quirked his fingers just so, finding that sensitive spot against Izuku’s velvety walls, pressing firmly against it.

Izuku screamed Katsuki’s name as he came on his face. Katsuki raised his head, dripping slick from nose to chin, and smiled wolfishly.

“So beautiful when you cry my name,” Katsuki licked his lips, pulling his fingers free of Izuku’s clenching pussy. “Taste so good, baby.”

He licked the mess from his fingers, tongue working overtime. Izuku groaned, already feeling his arousal coming back in full force.

“K-Kacchan…” he managed through heaving gasps, still coming down from the mind meltingly intense orgasm.

“Yes, baby?” Katsuki returned to pressing kisses along Izuku’s skin, up his thighs, around his navel, under the hem of his crop top. He slipped Izuku’s legs from around his shoulders, leading them to wrap around Katsuki’s middle.

“W-Want you…” he said, face flushed. “Want your cock, please.”

“Want me to fuck you, baby?”

Izuku groaned, nodding hard.

“Use your words, baby.”

“Hnn…ah… want you to fuck me, Kacchan. Please, please, I want your cock. Want to feel good.”

“Of course, love.” Katsuki murmured, kissing Izuku, spreading the taste of him across his tongue. They kissed long and deep until Izuku started rutting against his boyfriend, seeking that delicious cock.

Katsuki pulled his sweats off in a hurry, tossing them across the room without a care. He rubbed his pulsing dick along Izuku’s folds, spreading slick from base to tip.

“Kacchan!” Izuku whined.

“Mm, I’ve got you, Izuku. Don’t worry.” Katsuki pressed a chaste kiss to Izuku’s forehead before slipping the head of his cock into Izuku’s pussy, pushing the panties aside again. Slowly, so slowly, he stretched out Izuku’s insides until he was fully seated.

They both groaned at the feeling of being totally encompassed by the other. Katsuki steadied his breathing, evening out his heaving chest. Izuku clutched at the pillows beneath him, itching for more.

“How do you want me, baby?” Katsuki asked, rubbing hands up his stomach and under the crop top. “Soft and slow, or–”

“Hard. Fuck me fast and hard, Kacchan! Now!” Izuku wailed, digging nails into Katsuki’s shoulder.

Katsuki snickered, lips curling into a pleased grin.

“Of course baby, anything you want.” Katsuki kissed him again, then whispered against his lips, “Hold tight.”

Izuku barely had time to comply before Katsuki was pulling back and slamming back in. Katsuki’s hands gripped bruisingly around Izuku’s hips, tender, plump flesh spilling between his fingers.

He pulled Izuku down on his cock as his hips thrust forward, the slick slap slap slap of their moistened skin a rhythmic pulse in their ears.

Katsuki pistoned into Izuku relentlessly, grunting and groaning like he couldn’t get enough of him. Izuku dug his fingers into Katsuki’s hair, dragging him down for a raveging kiss.

Katsuki didn’t even break his pace, hunched over as he was, grinding Izuku down into the pile of pillows.

“Ah ah ah!” Izuku’s breath was punched out of his chest with each pounding slap, “Ka-hah-chan! I’m gonna! I’m–”

“Come for me, beautiful.” Katsuki growled, tongue snaking out to lap up the overwhelmed tears spilling from green eyes.

Izuku cried out, body tensing and clenching around every inch of Katsuki he could reach.

Digging fingers into blonde hair, raking from scalp to back, legs tightening around his trim waist, squeezing until Katsuki groaned in pleasure-pain, hole milking Katsuki’s massive cock carving out its rightful place within Izuku’s cunt.

Flickers of green lightning flashed through the dim room, sending their features into sharp relief. Izuku felt Katsuki’s palms heat up to near pain, leaving faint pink marks of his hands around his hips as Katsuki’s pace finally stuttered.

Katsuki, hunched over, breathing hard, fingers squeezing, came deep inside Izuku.

They laid there, recovering from their simultaneous orgasms, breathing hard, trailing lazy kisses over any inch of exposed skin they could reach.

When they both came back down, Katsuki groaned, rolling over so he wouldn’t crush Izuku, pulling him in tight to curl over him and nuzzle into damp curls.

“Mm, Kacchan…” Izuku murmured with a wobbly smile.

“Izuku,” Katsuki said, kissing his temple. “Feeling better?”

“Mmhmm,” Izuku turned to duck his head into Katsuki’s chest, happily squishing his face between his statuesque pecs. “Much. Thank you.”

“No need to thank me, baby. You’re beautiful. You’re so fucking beautiful, and I’ll do anything to remind you of that every fucking day.”

Izuku squirmed happily in Katsuki’s tight embrace, pressing kisses to his collarbone.

“Love you,” Izuku whispered into his chest.

“To the moon and back.” Katsuki said, chest rumbling with the familiar words.

Katsuki always had a way of turning Izuku’s worst days into something wonderful, and he loved him for it.
