Izuku whimpered as Katsuki tugged the last knot into place. He hooked two fingers underneath the tie and pulled, double-checking the tightness. Katsuki let out a quiet hum of approval, deeming the hold to his standards: loose enough not to cut off Izuku’s circulation but tight enough to leave marks that he would trace dreamily the next day. Izuku groaned as Katsuki’s fingers slipped free, the comforting bite of hemp digging back into the tender flesh of his thigh.
Katsuki’s fingers slowly traced down the intricate, methodical, interweaving ropes that looped around his thighs and calves, binding him into a frog tie that left his legs obediently splayed open — easy access for Katsuki’s convenience. Izuku squirmed against the ropes, arms bound above his head and unable to close his legs with his husband between them as Katsuki’s hot hand skirted over his inner thigh. The delicate touch was dangerously close to where Izuku was quickly growing needy.
Katsuki delivered a quick, sharp slap to the crease of Izuku’s thigh. Izuku’s teeth dug into his bottom lip as he moaned, trying to stifle the pathetic sound.
“Thought you were gonna be good for me tonight, baby,” He quipped. His hand roughly grabbed Izuku’s chin, forcing the other to look at him. He traced his thumb along Izuku’s bottom lip, where his teeth still dug into the supple flesh. “Don’t tell me you’ve changed your mind already.”
“N-no, Daddy….” Izuku whispered, his shaky breath ghosting across Katsuki’s hand.
“Good,” Katsuki rumbled and released his jaw. His hand returned to stroking Izuku’s thigh, soothing where the heat of his strike still radiated his skin. “‘Cause, as I recall, I have plans for tonight.” Katsuki's nails suddenly pressed into his skin. He slowly raked up his abdomen with just enough pressure to raise goosebumps in his wake. “Care to remind me of those plans, baby boy?”
He recalled the words Katsuki had growled into his ear as he weaved the first length of rope around his wrists with perfect clarity — despite the haze he already felt descending upon his mind.
“Y-you said you were going to t-tie me up….” He started slowly, tongue feeling like cotton in his mouth. “And that you were going to make me cum as many times as you wanted, S-Sir.”
“Good,” Katsuki growled. He rewarded Izuku with a wet kiss on his neck, hot tongue lapping over the sensitive skin. He scraped his teeth against him, and Izuku shuddered. “What else?” He demanded.
“You wanted me to stay still and take it like a good boy, Sir.”
“That’s right,” Katsuki grunted, fingers just barely stroking the edge of his cunt, not close enough to cause any real pleasure, though Izuku could still feel himself throb. “Don’t you want Daddy to be nice to you tonight, Sweetheart?”
The thought of bratting tonight had never crossed Izuku’s mind. Their everyday sex life wasn’t necessarily vanilla, but they could only have more intense, detailed scenes like this on their shared days off. And the past two weeks, they’ve worked nearly opposite shifts, which resulted in only a handful of barely satisfying late-night quickies.
Izuku felt like he was going to Detroit Smash someone into the stratosphere out of pure sexual frustration if he didn’t get some relief soon. He wanted more than anything to find reverie in his husband’s authoritative touch.
“Please, Daddy,” He whined, his voice tight with desperation. “Wanna be good for you.”
“Then relax, baby.” Katsuki crooned. His warm, honeyed tone washed over Izuku, who took a deep breath and sagged obediently into his bindings. Hot hands ghosted up and down Izuku’s sides before settling on his chest, squeezing his soft pecs. A calloused thumb ghosted over Izuku’s nipple, and his breath caught in his throat at the sudden jolt of pleasure.
Katsuki’s hands roamed over his torso, tracing the contours of his abdomen and squeezing greedy handfuls of Izuku’s hips, waist, thighs, and pecs. Izuku lost himself in Katsuki’s rapacious caress, eyes slipping shut as powerful hands explored his vulnerable body.
“Love this color on you, baby,” Katsuki crooned. Izuku slowly blinked opened bleary eyes and watched as Katsuki hooked his fingers underneath the dark red ropes that bound his chest, squishing his pecs together and making them appear fuller. Izuku had picked out the color himself, the same as Katsuki’s eyes.
Avaricious hands groped his chest again, and Izuku shuddered. Katsuki watched with rapturous glee as the soft muscles flushed a rosy pink in his grasp and then faded back to creamy fawn as he released his hold, flesh spilling over the wine-red rope. A moan fell from Izuku’s lips, wanton and unrestrained.
“Yeah? You like lookin’ pretty for Daddy, baby boy?”
“Y-yes, Sir!” Izuku gasped as deft fingers brushed against his nipples. Katsuki rubbed soft, slow circles over Izuku’s nipples before scraping his nails against the peaking buds. Katsuki took one nipple in his mouth, lapping hot, languid licks while he pinched and rolled the other between persistent fingers.
Izuku couldn’t hold back the moans and sighs that fell freely from his lips. He felt himself grow slick between his thighs. His bare, neglected cunt drooled hot, viscous, and needy. Katsuki’s hot mouth popped off his nipple, moving to suck a bruising kiss onto the soft, tender skin of his pec.
Once Katsuki was satisfied with the marks he sucked into Izuku's chest, he moved on to the other side, rubbing his drying saliva into Izuku’s skin as he rolled his tongue against the other nipple. Katsuki teased, pinched, and suckled at Izuku’s pecs as he pleased. Sharp teeth grazed Izuku’s sensitive nipple, and he keened, hips thrusting jerkily against his restraints at the sudden, sharp jolt of pleasure.
Katsuki’s hand slapped hard against Izuku’s exposed cunt and he yelped, muscular thighs flexing, instinctively trying to clamp together. Katsuki spanked his cunt again and Izuku sobbed, hot tears spilling over his cheeks.
“So needy,” Katsuki chastised, delicate fingers petting affectionately over Izuku’s cunt. He marveled at the string of slick that connected his palm and Izuku’s drooling pussy as he pulled away. “This wet already? We’ve barely even started.”
Izuku whimpered at the loss of Katsuki’s tender touch. His pussy ached, hot and tingling after only a couple of slaps.
“Daddy hasn’t been taking care of you lately, has he, baby boy?” Katsuki cooed, soothing calloused fingers over Izuku’s throbbing clit. “Not been using this pussy like he should, huh, baby?”
Katsuki pinched Izuku’s clit and rubbed it between his fingers. Izuku sobbed, willing his straining thighs to remain still as Katsuki jerked his little cock. “Well, don’t you worry, baby boy,” Katsuki crooned, rubbing hard circles against Izuku’s twitching t-dick, “Daddy’s got all the time in the world tonight, and he’s gonna spoil you fuckin’ rotten.”
And just like that, Izuku’s first orgasm tore through him. The muscles in his thighs and abdomen flexed as he went rigid, a wave of slick leaking from his pink little cunt as he cried out.
“Good fuckin’ boy, Izuku,” Katsuki growled, his fingers still working over Izuku’s clit, milking his first orgasm until Izuku sobbed again.
“T-too much…! I c-can’t… Daddy, please—!”
“Yes, you can, Deku,” Katsuki ordered, meanly pinching and rolling his clit between his fingers. “Gimme another one, Sweetheart. That’s it, cum for Daddy, baby.”
Izuku’s voice cracked as he cried, hips jerking in aborted half-thrusts that Katsuki decided to forgive. He finally ceased the incessant rubbing of Izuku’s clit, softly petting the sensitive nub.
“Good boy, Izuku. You did so good for me, baby.” Katsuki pressed gentle kisses to Izuku’s face and neck between murmured praise. His tongue traced the drying rivulets that stained Izuku’s skin, his teeth sinking into a freckled cheek.
“Mmm, taste so good, baby,” Katsuki hummed, kissing the faint indentation of his teeth. “Bet you taste even better down here.” His fingers drifted from Izuku’s sensitive dick to where he was desperate and leaking. Izuku whimpered.
“What’s your color, baby?” Katsuki whispered before sucking a bruise beneath his ear.
“G-green, Sir,” Izuku mumbled.
Katsuki nipped his ear, “That’s my good boy.” His hands slowly traced over Izuku’s waist and hips as he repositioned himself between trembling thighs. “Been thinkin’ about this pretty little pussy all fuckin’ week.” He growled, licking a broad stroke from Izuku’s seeping cunt up to his throbbing clit.
Izuku’s hips jumped at the contact and Katsuki growled, fingers digging into Izuku’s hips as he pinned them to the mattress. He whined as Katsuki softly kissed his clit, hot tongue petting over his tender cock, licking and sucking Izuku’s clit like he was making out with it.
He groaned in tandem with Katsuki, the sound vibrating through his core as the thick muscle lapped at his leaking entrance. Izuku let out a stuttering gasp as Katsuki’s tongue breached his pussy. His walls clenched around Katsuki as his tongue stretched him open, lapping up his arousal like it was sweet honey.
Katsuki’s tongue slipped out of his fluttering cunt as he came up for air, panting hot breaths against Izuku’s sticky pussy, slick with saliva and arousal. “God fuckin’ damn, Deku,” He grunted.
Using his thumbs to spread Izuku’s folds open, he watched as a fresh wave of arousal dripped from his entrance. Katsuki chased it with his tongue, moaning at the musky, salty-sweet flavor that was so distinctly Izuku. He dipped his tongue in and out of Izuku’s pussy, just to feel the way his muscles spasmed around him, trying to draw him deeper inside.
Izuku groaned, slutty and unabashed, as Katsuki’s lips wrapped back around his sensitive little cock. Katsuki kissed, licked, and sucked with fervor. Izuku’s nails bit into his palms, abs clenching and thighs straining, his body wracked with indecision. He couldn’t decide if he wanted to escape the onslaught of overstimulation or if he wanted to chase the bittersweet, electric sensation.
But there was no decision to be made — that was Katsuki’s job. All Izuku could do was lie there and take whatever pain or pleasure Katsuki inflicted at his whim.
An ardent, intoxicating feeling washed over Izuku’s body and resonated through the tips of his numb extremities as he slipped into a tender, acquiescent headspace. He didn’t register the mewls of “Please” and “Daddy” that fell from his lips nor the hot tears that slipped down his flushed cheeks. The only sensation he was cognitive of was the rough texture of rope constricting his body and Katsuki’s burning touch — his only tether to reality as he floated on the precipice of vacuous euphoria.
Subconsciously, as Izuku’s pleasure began to reach its fever pitch once more, his body sought out Katsuki’s touch, trailing after his tether even as it pulled away. He lacked the lucidity to realize he was breaking Katsuki’s rules. His thighs strained to hold Katsuki in place as his hips bucked, fucking his hard little clit against Katsuki’s rough tongue.
“Yes, yes, yes, Daddy, ah—!” Izuku whined as he humped Katsuki’s face. His toned thighs strained against the ropes, the soft hemp digging into his freckled skin. Izuku whimpered at the pain, but it did nothing to deter him from desperately fucking his dick into Katsuki's mouth. The burning pain mixed with white-hot pleasure only spurred his eager hips forward as he neared the peak of his climax.
“Oh, oh, Daddy! I’m gonna cum! ‘M c-cumming! Daddy!”
Izuku groaned as his hips finally stilled. His dick twitched against Katsuki’s tongue as he continued to lick and suck Izuku through his orgasm, slick leaking from his clenching cunt and staining Katsuki’s chin.
Katsuki didn’t release his suction on Izuku’s clit until he was whining from the overstimulation again. Izuku sank into the mattress, shuddering as his bound thighs finally relaxed and splayed open around Katsuki’s torso.
Suddenly, Katsuki’s large palm slapped down on his sticky cunt, punching a groan from Izuku’s throat. He jumped from the sharp pleasure, his clit hot and tingling.
“Bad boy, Izuku,” Katsuki growled and spanked his pussy again. “Such a dumb fuckin’ whore. So damn desperate that you can’t even follow simple fuckin’ instructions?” Katsuki reeled his hand back and slapped it down on Izuku’s clit, hard.
“K-Kacchan!” Izuku squealed, jolting as his legs clenched around his husband’s waist.
“Wrong fuckin’ name, baby.” Katsuki spanked Izuku’s cunt twice more in quick succession before shoving two fingers into his weeping pussy. Without giving him time to adjust, Katsuki curled his fingers and began roughly fucking in and out of his cunt, striking Izuku’s g-spot.
“D-Daddy! Daddy!” Izuku sobbed and hiccupped, his red, swollen pussy squelching around Katsuki’s thick fingers as they pistoned inside him. A hot, prickling sensation radiated through his cunt; jolts of electric ecstasy lighting up his over-sensitive nerves each time Katsuki jabbed into his sweet spot.
“Such a slutty fuckin’ cunt,” Katsuki grumbled with a sadistic sonorousness as he watched Izuku writhe on his fingers. He felt Izuku’s walls clench around him, slick drooling down his palm. “So fuckin’ easy, baby,” He snickered, “Ya gonna cum again already?”
“Y-yes!” Izuku gasped as Katsuki’s fingers stilled their incessant thrusting, instead grinding against his g-spot. “I’m so close! Please, Daddy, please let me cum!”
“Yeah, that’s it,” Katsuki groaned, hips jerking. His cock strained against the damp fabric of his underwear as he rutted into the mattress. “Cum for Daddy like a good bitch.”
Katsuki’s fingers suddenly resumed punishingly pounding into Izuku’s g-spot and Izuku wailed. He moaned and whimpered, his abdomen strained and flexed as he felt pressure well up inside him.
“Oh! Ah, mmngh, I-I can’t— I’m gonna! D-Daddy—!” Izuku’s jaw dropped in a silent scream, head thrown back against the pillow as his thighs shook around Katsuki. Hot liquid gushed from his burning cunt, soaking Katsuki’s wrist and their bed sheets.
“That’s a good fuckin’ slut,” Katsuki grunted. He pulled out of Izuku’s trembling cunt, thick strings of cum webbing between his fingers. A loud, obscene, wet slap reverberated through their bedroom as Katsuki spanked his pussy once more. A broken groan resounded from deep in Izuku’s throat.
Using his thumbs, Katsuki stretched his entrance taught again. His sharp eyes gleamed avariciously as he watched Izuku’s cunt clench and spasm. He spat onto Izuku’s wet folds and then used his fingers to fuck his saliva inside.
Izuku whimpered when calloused fingers withdrew from his cunt again. Katsuki lifted his hand to Izuku’s mouth, smearing his slick against his bottom lip.
“Clean my fingers, Deku,” He ordered.
Izuku complied eagerly, moaning as soon as the mixed flavor of his arousal and Katsuki’s sweat and saliva melted on his tongue. He sloppily sucked on Katsuki’s fingers with fervor, his tongue caressing each callous with delicate reverence. He fantasized about his husband’s throbbing cock as he sucked. He knew Katsuki must’ve been aching with arousal. A patch of his underwear near the thick head of his cock was wet with precum.
“Fuck,” Katsuki gritted out as Izuku groaned around his fingers. “You look like such a fuckin’ slut, Deku.”
He pressed down on Izuku’s tongue, hooked his fingers behind his teeth, and forced his mouth open. Katsuki spat on Izuku’s tongue and he keened. Katsuki fucked his fingers down Izuku’s throat, teasing his gag reflex and making his big doe eyes water. He pulled his fingers out and spit into Izuku’s mouth again. Without needing to be ordered, Izuku let the wad of saliva slide down his throat with a bob of his Adam’s apple. His mouth dropped obediently back open, tongue lolling out to show Katsuki what a good job he did.
“Good boy,” Katsuki growled and pressed a rough, bruising kiss to Izuku’s open mouth.
Katsuki dominated Izuku’s pliant mouth, biting and sucking at plush, swollen lips. He fucked his saliva into Izuku’s mouth as their tongues caressed. Strong hands framed Izuku’s jaw and tangled in messy viridian curls as he moaned unabashedly into the kiss.
Their kiss slowly devolved from bruising and biting to loving, languid licks. Katsuki’s hands wandered from Izuku’s curls to grope at his chest again, where love bites began to purple against his freckled skin.
Katsuki always took such good care of him when they got like this, knowing exactly when to praise or to punish. It got Izuku so high, like a kite soaring up into the clouds. And Katsuki was there with delicate fingers that pulled his strings to guide him, to keep him grounded and steer him away from turbulent winds. He directed Izuku into that euphoric headspace, piloting him along the crest of lucidity. And he was there to pull Izuku gently back to the ground, strong arms open to catch him when he landed.
Katsuki peppered wet kisses down Izuku’s neck, sucking more hickeys into tawny skin that he knew would fluster his husband the next day. “What’s your color, baby?” He asked, skimming a hand down to where Izuku was still wet and throbbing.
“Mmm, green, Daddy.”
Enraptured, Izuku watched as Katsuki tugged off his boxers, finally releasing his cock. He resisted the urge to clamor after it, to lick it clean of precum until it was dripping with his saliva and ready to fuck his sore cunt. But he didn’t have Katsuki’s permission to touch, so he waited with barely restrained anticipation.
Katsuki’s fingers trailed over his cunt, dragging long, calloused fingers through throbbing folds, and then slicked himself with Izuku’s arousal. He wrapped his large hand around his dick and pumped himself. He let out a long, drawn-out groan from deep in his throat as he slathered his cock with Izuku’s slick, finally stimulating his neglected cock.
“Daddy, please….” Izuku whined, pussy clenching as he watched Katsuki jerk himself. He hiked his legs up, baring his needy cunt to Katsuki as best he could without the assistance of his hands.
Katsuki grunted, grabbing his dick at the base and squeezing one last time before shuffling between Izuku’s open thighs. He slapped the head of his cock down on Izuku’s swollen clit, eliciting a moan from both of them.
“God damn….” Katsuki groaned as he watched Izuku’s pussy twitch sporadically, flushed red, swollen, and hot to the touch from his spankings. He fucked his dick between wet folds, bumping the head of his cock against Izuku’s clit. He continued to frot his dick between Izuku’s folds. His fingers gripped his husband’s hips hard and he let out a possessive grunt as he watched Izuku’s pussy cream on his cock.
“Daddy, Daddy, please put it in,” Izuku mumbled as he rocked his hips up to meet Katsuki’s lethargic thrusts. Katsuki slapped his cock down on Izuku’s clit again, making his breath hitch.
“I don’t know, baby,” Katsuki drawled with a teasing lilt, his thumb just barely ghosting over his clit as he circled the sensitive nub. “I think I might cum just like this,” He thrusted against Izuku with a grunt, and the head of his cock bumped against Izuku’s. “Mark this slutty little pussy with my cum. You want that, baby?”
Izuku let out a broken groan because he did want it. The thought of Katsuki marking him with his hot cum until he was dripping with it made his cunt throb.
But he needed Katsuki inside him. He waited too long and was teased too much not to feel that thick cock finally stretch him open. He bit his lip and shook his head, messy curls bouncing against the pillow.
“No?” Katsuki hummed, his hips slowing to a stop. He leaned down, sharp eyes boring into Izuku’s hazy, wide-eyed teary gaze. “What is it that you want, Sweetheart?” His breath grazed across Izuku’s lips, his voice low and resonant.
“W-want your cock, Daddy,” Izuku’s voice wobbled, “Need it inside, Sir.”
Katsuki hummed contemplatively, resuming the slow rut of his cock against Izuku’s weeping cunt. “I’m not sure if you deserve it, baby,” He crooned.
“Said you were gonna be good for Daddy, but you broke my rules more than once tonight.” The tip of Katsuki’s cock caught against Izuku’s hole, the thick head just barely stretching his walls before sliding back out. A whimper left Izuku’s lips, broken and pathetic. “Do you think you deserve it, baby boy?”
Izuku sniffled, hot tears welling in his glassy, downcast eyes.
He knew that Katsuki was right. He couldn’t follow the one rule Katsuki gave him. He was too eager, too desperate for his husband’s touch, and too caught up in his own pleasure when he should’ve focused on staying obedient and pleasing Katsuki.
“I’m sorry, Sir,” He warbled, tears spilling over his cheeks as he sniffled and hiccuped. “I’m sorry, d-didn’t mean to, Daddy. Wanna be good, Daddy, please….”
“I know, baby,” Katsuki shushed him, thumbing away the tears that slipped down his freckled cheeks. “You gotta convince me, though. Gotta show me you wanna make it up to me. Tell Daddy how badly you need it, Sweetheart.”
Katsuki slowly rolled his hips against Izuku. His cock was red, swollen, and leaking precum all over Izuku’s cunt from being hard and untouched for so long. Izuku whimpered at the sight, tongue wetting his dry, kiss-bitten lips pensively. He was aching for it, wanted it so fucking bad. His cunt was hot and tingling, oversensitive from Katsuki’s spankings, yet still eager to be touched.
He angled his hips up, the head of Katsuki’s cock caught on his entrance again, and Izuku groaned. He needed to feel the stretch of Katsuki filling him up and making him whole. He needed to feel the hot release of Katsuki’s seed inside him. He needed to know that he did well and made Katsuki feel good.
“Fuck, that’s it, baby, keep goin’,” Katsuki groaned, hips losing rhythm for a moment and jerking against Izuku’s pussy. Izuku hadn’t realized he started mumbling his thoughts out loud.
“D-Daddy…!” Izuku gasped when Katsuki began teasing his entrance with the thick head of his cock, popping just the tip in and out of his hole. Izuku reveled in the almost painful stretch, pussy already squelching from the shallow thrusts.
“I’m sorry, Sir, I’m sorry! Please, I need your cock!” He cried, head thrown back and gasping for air. “Wanna be good! Want you to use my pussy! Daddy, please, please fuck me!”
“Yeah? You wanna be Daddy’s pretty little cocksleeve?”
“Yes!” Izuku keened and writhed against his bindings, “Wanna be Daddy’s cocksleeve! Use me, fuck me, cum inside me, please! Need it, Daddy, need your cock, please….”
“Well, since you asked so nicely,” Katsuki grunted and shoved his dick to the hilt inside Izuku’s trembling pussy. A pathetic-sounding groan punched from Izuku’s throat, slack-jawed and shuddering from Katsuki’s girth intruding his fluttering cunt.
“Fuck,” Katsuki groaned as he inched halfway out before thrusting back in. “Always know how to beg like a good fuckin’ bitch, don’tcha?” He growled. Izuku could only utter a broken moan in reply, his voice pitching.
“Perfect fuckin’ slut.”
Izuku could do little more than whimper and cry on Katsuki’s cock as their hips met with wet thrusts. His pussy clenched tight around Katsuki at each degrading name and reverent praise that fell from his filthy mouth. Katsuki angled his hips, his dick striking Izuku’s g-spot with each thrust. Izuku keened and bucked his hips up to meet Katsuki’s.
“That’s it, Izuku,” Katsuki grunted, “Take that fuckin’ cock, baby.” His hand snaked up from Izuku’s hips to one of his pecs, groping the bruised flesh and thumbing at his sensitive nipple.
Izuku cried out, cunt spasming. Each bump against his g-spot and roll of his nipple ignited electric, white-hot pleasure in his throbbing clit.
“O-oh! Mmngh, ah… ‘m cum… c-cumming! ” Izuku sobbed, hot bursts of slick gushing around Katsuki’s cock as he continued to fuck his husband through his fifth orgasm of the night.
“Good boy,” Katsuki groaned, “So fuckin’ tight, keep squirtin’ on my cock, baby.”
Izuku whimpered when Katsuki suddenly pulled out. He squeezed the base of his cock and watched squirt dribble from his husband’s now gaping cunt. Katsuki grasped Izuku’s bound legs and folded his torso up until his knees brushed against his ears, giving Katsuki a better view of his puffy wet pussy.
He watched as Izuku’s pussy clenched, squeezing helplessly around the missing girth that had stretched him open. “So good for me,” Katsuki rumbled and placed a chaste kiss on Izuku’s swollen little dick before taking hold of his cock again.
“Fuckin’ made for this, weren’t you, Sweetheart?” He mused, rubbing his leaking cock against dripping folds. “Meant to look pretty and take dick, isn’t that right?”
After Izuku didn’t respond, he slapped his cock against Izuku’s clit, “I said, isn’t that right?” He demanded, voice low and hard just for show.
“Y-yes! Yes! ‘M made for your cock!” Izuku bawled.
Katsuki moaned and popped the head of his dick back into Izuku’s tight, wet heat. He shallowly fucked into Izuku’s cunt, never thrusting in more than a few centimeters.
“D-Daddy,” Izuku hiccuped. He squeezed around Katsuki each time he withdrew from his pitiful cunt, subconsciously trying to persuade him to stay inside. “Please fuck me,” He whined, his big, round eyes welling with tears.
“I am fucking you,” Katsuki grunted.
“No!” Izuku whined again and shook his head desperately. “D-deeper— mmph! Need it deeper— ngh! I-Inside!”
He grunted as he tried to buck his hips up to meet Katsuki’s thrusts, but it was pointless. Katsuki had him thoroughly pinned beneath his looming weight, without an inch of give.
“Nah,” Katsuki replied, “Gonna make you cum just from this.”
“B-But I’ve been good!” Izuku blubbered, huffing as he tried to wriggle out of Katsuki’s hold.
Katsuki reeled his palm back and spanked Izuku’s ass with a resounding smack! “You’re not gonna get what you want by acting like a fuckin’ brat!” He barked.
“If you wanna be good, take what I give you and cry for me like an obedient little slut should.” He grabbed Izuku’s jaw in one large hand, squished his sticky cheeks until his mouth dropped open, and hooked his thumb behind Izuku’s teeth.
Izuku whined, hiccuped, and sobbed as Katsuki continued to shallowly fuck his cunt. Drool, snot, and tears leaked freely from his flushed face. He struggled to keep his eyes on Katsuki, unable to keep them from rolling back each time the head of his cock forced its way back into his tight little cunt.
“Fuck, that’s it, Izuku,” Katsuki moaned, “Love it when you fuckin’ cry for me, baby. Such a good fuckin’ boy. S-Shit!”
He quickly released Izuku’s jaw and hissed as he squeezed his hand around the base of his dick, trying to stave off his impending orgasm.
“Daddy! Daddy!” Izuku wailed now that his mouth was free. “‘M close—! Please, can I cum? Please, Daddy, need to cum, please, please, please—!”
Katsuki suddenly slammed inside to the hilt. Izuku didn’t hear the scream that erupted from his throat nor the deep groan that rumbled from Katsuki’s. He didn’t see the lust that clouded his husband’s face, his vision whiting out as Katsuki gripped their hips flush and pumped deep inside him. His pussy clenched tighter and tighter, slick and cum gushing from his cunt between staccato thrusts.
Izuku came back to himself after a few moments, gently descending from the ecstatic cocktail of endorphins from cumming his brains out and back into that pleasant, floaty headspace. He whimpered as Katsuki pulled out with a grunt and unfolded Izuku so he could lay as comfortably as he could on the mattress with his limbs still bound.
“Fuck, Izuku,” Katsuki moaned, thumbing his spend back inside, where it began to leak from Izuku’s hole. “You look so fuckin’ good, baby,” He grumbled, shimmying his way down between Izuku’s open thighs, “Good enough to eat.”
Katsuki swiped a hot tongue through Izuku’s slit and moaned at the combined taste of their arousal. A broken whine emitted from Izuku’s throat as Katsuki’s calloused thumb brushed his clit.
“No,” He whimpered. Fresh tears welled in his glassy eyes and shimmered in the dimmed lights of their bedroom. “No more,” He hiccuped, “‘S too much, Daddy.”
Katsuki cocked an unimpressed eyebrow at Izuku as he continued to leisurely lap at his pussy like a cat that got the cream.
“You know your colors, Sweetheart,” He drawled, backing away from Izuku’s cunt, and looked up at his husband expectantly as he began to wriggle uncomfortably from Katsuki’s sudden lack of touch.
“… G-green.”
Katsuki chuckled and resumed licking Izuku’s dripping cunt.
Izuku huffed and whimpered, a steady stream of crocodile tears descending ruddy, freckled cheeks. Mumbled pleas of “no more” and “stop, Daddy” fell upon deaf ears as he continued to beg his husband for mercy. His poor little clit was over-sensitive and swollen from so much attention, but Katsuki continued to circle his thumb around it with benign amusement.
Katsuki licked and sucked at Izuku’s pussy until he could no longer taste himself and only the sweet, unadulterated taste of his husband’s syrupy slick. He worked Izuku over slowly and thoroughly, rubbing his clit with soft, lethargic strokes in tandem with deep flicks of his tongue. He stoked Izuku’s arousal until he was burning with the need to cum again. Suddenly, it was no longer cries of “too much” that fell from dulcet, kiss-bitten lips, but instead breathtaking gasps of “not enough” and “more, Daddy, please!”
Hot, viscous slick flooded Katsuki’s mouth as Izuku cried out above him, bound thighs trembling with pleasure. He pulled back with a satisfied groan and licked his lips clean of Izuku’s cum. “Thanks for the meal, baby,” He said with a toothy grin.
“Daddy,” Izuku mumbled, plush lips tugged down into a pitiful little pout, “Want your cock. Put it back in, please?”
“So spoiled,” Katsuki grumbled affectionately as he hefted himself up, cock hard and heavy between his legs once again. He kissed the pout right off of Izuku’s pursed lips. “Anything for you, baby.”
Katsuki guided his cock back to his husband’s puffy, wet entrance, Izuku’s jaw dropping as he sheathed the entire length inside with a single push. A pleased sigh exhaled through Katsuki’s nose, thumb tenderly tracing the ropes that bound Izuku’s thighs as he basked in the tight, comforting heat that embraced him.
He moaned as he slowly pulled out of Izuku, “Fuck, so good for me, baby boy.” He shoved his hips forward, knocking a groan from Izuku as he forced his way deep inside.
“So perfect. So pretty. Pussy’s so fuckin’ wet. Fuckin’ made for me, Izuku,” He murmured between amorous kisses. Izuku’s lips chased his, huffing each time Katsuki pulled away to mumble more filth and praise against his freckled skin.
Their hips rocked together robustly, the sounds of their coupling resounding through their bedroom as Izuku’s pussy leaked steadily around Katsuki’s surging cock.
“Fuck, you hear that, baby?” Katsuki grunted. He pressed Izuku’s thighs into the mattress so they were spread wide around his hips. “D’ya hear how fuckin’ wet you are for me?”
Izuku whimpered in response, his cunt clenching tighter around the cock fucking deep inside him.
“Fuck, that’s it,” Katsuki groaned, his grip on Izuku’s thighs became bruising. “Such a slutty little pussy. Think you can squirt again, baby?”
Izuku sobbed and shook his head, unable to articulate anything other than broken moans and slurred cries of “Daddy.”
“Come on, baby,” Katsuki growled, releasing one of Izuku’s thighs to rub his swollen little dick again. “One more time, Izuku. Squirt on Daddy’s cock, Sweetheart.”
Izuku threw his head back and wailed, legs shaking uncontrollably as Katsuki plowed into him and teased his sensitive clit. He gushed around Katsuki, slick dribbling out around his husband’s dick each time he withdrew and fucked his way back in.
“Fuck, Izuku, take it, baby, fuckin’ take it,” He pressed his face into Izuku’s neck and rambled nonsense into his ear as his rhythm faltered, pumping erratically into his creamy pussy as he chased his own orgasm.
“So good for Daddy, Sweetheart, such a good fuckin’ boy. Gonna make me cum, baby, fuck! ‘M cummin’, Izuku, Izuku, Izuku! ” Katsuki came with a groan, hips stilling suddenly, twitching minutely as he pumped his cum deep inside.
Izuku slowly willed enough strength to blink open his heavy eyelids; his mind still clouded in a euphoric fog. He wasn’t sure how long he’d dozed off, but it was long enough for Katsuki to untie his bindings. His husband sat on the edge of their bed, methodically looping the last length of rope around his hand, prepping them to be stored away until their next use. A soft sound escaped Izuku as he watched his husband, and Katsuki’s head quickly whipped around.
“Hey, baby,” Katsuki spoke, his voice soft as he tenderly brushed Izuku’s bangs out of his face. “Are you back?”
Izuku leaned into his warm touch and mumbled a quiet, “Mm, Daddy….”
“Nah, still under,” Katsuki tsked, “That’s alright, Sweetheart, you stay there as long as you need.” He stroked Izuku’s messy curls, detangling the occasional knot as he ran his hand through his hair. Izuku hummed appreciatively at the grounding, affectionate gesture.
Katsuki’s hands drifted away from Izuku’s hair and returned with a damp rag a moment later. Izuku whimpered at the first contact with his sore cunt, trying to close his thighs to protect his sensitive sex.
“I’m just tryin’ to clean you a lil, Izuku,” Katsuki hushed him as he coaxed his shaky legs back open. “I’ll be gentle, promise.”
Izuku whined as Katsuki cleaned him, jolting each time the rag passed over his clit.
“All done,” Katsuki said after a moment, tossing the rag to the side. “Still hafta get you in the bath, though.”
“Here,” Katsuki helped Izuku prop his head up and handed him a bottle of water. “Can you hold it yourself?” Izuku nodded, took the bottle from Katsuki, and downed several long gulps of water. He handed the bottle back after nearly draining it entirely.
“Good boy,” Katsuki praised, taking the bottle and setting it aside on their nightstand. “You did well today; cried for me a lot, baby.” He ruffled Izuku’s hair one last time before standing, “Alright, bath time, Nerd.”
Izuku made grabby hands up at Katsuki and looped them around his broad shoulders as he leaned down. “Up we go,” Katsuki grunted as he hefted Izuku up. He hummed happily and buried his face in Katsuki’s neck, breathing in his spiced, musky scent as his husband carried him into their en-suite bathroom.
Katsuki plopped Izuku down on the toilet and began drawing the bath, adjusting the temperature of the water until he was satisfied. He turned to Izuku and said, “I’m goin’ to strip the bed. Use the bathroom while I’m gone, and I’ll be right back, okay?”
Izuku nodded. While he could feel himself slowly descending from his high, he couldn’t quite find it within himself to form any words just yet.
By the time Izuku finished relieving himself, Katsuki had reentered their bathroom, an armful of dirty sheets in tow. He dumped the sheets in their hamper and walked to the tub, ruffling Izuku’s hair as he passed by him. He checked the temperature of the water one last time before shutting the faucet off. He turned and extended his hand to Izuku, “Can you stand by yourself?”
Izuku took Katsuki’s hand and attempted to stand, but his legs shook and quickly buckled beneath him.
“That’s a no,” Katsuki chuckled as he caught Izuku, steadying him and guiding him into the bath.
Katsuki settled behind him in the tub, strong arms bracketing Izuku as he relaxed into the warm water. Katsuki lathered soap onto a cloth and washed Izuku’s back, working his hands over tensed muscles. “Mm, Kacchan…” Izuku mumbled, “That’s nice.”
Katsuki stroked his hands down Izuku’s arms and traced the red lines from where he’d been tied. “Sore anywhere?” He asked.
Izuku hummed contemplatively, letting his eyes drift shut as Katsuki’s hands worked him over, “Mmm, yeah, but not a bad kind of sore… feels good.”
“Masochist,” Katsuki teased and thumped the back of Izuku’s head.
“Hey—!”
“Shut up and lay your head back, Nerd, I’m gonna wash your hair.”
“What happened to Baby and Sweetheart?” Izuku huffed as he leaned back.
Katsuki sprayed him in the face with their retractable shower head, and Izuku spluttered.
“Brats don’t get pet names. Now be a good boy and sit still for me.”
Izuku leaned his head back and savored the way Katsuki’s trimmed nails scratched lightly at his scalp, working the shampoo into his hair. Warm water cascaded down his back as his husband rinsed his hair. Izuku heard a cap pop open behind him, and Katsuki scrunched more product into his curls.
“We’re almost out of the conditioner that you like.” Izuku could tell from the slight dip in his voice that Katsuki was frowning at the bottle with contempt before putting it away.
“I’ll stop at the store on the way back from my next patrol,” Izuku sighed, sinking into Katsuki’s chest and enjoying the warm, wet contact of their bare skin. A moment of comfortable silence passed as Katsuki absentmindedly played with Izuku’s curls and rinsed the conditioner from his hair.
After a minute or two, Izuku began to wriggle out of Katsuki’s hold, water sloshing against the rim of the tub.
“Turn around. I wanna wash you too, Kacchan.”
“Watch it, Nerd!” Katsuki barked, “You’re gettin’ water all over the floor!”
“It’s just water, Kacchan.”
“Like hell it’s “just water,” it’s still a damn mess.” He nagged, begrudgingly shifting around so their previous position was reversed.
Izuku rolled his eyes as he lathered Katsuki’s toned back. “Don’t be so dramatic. I’ll clean it up, okay? Now hush and let me wash your back, Kacchan.” He resisted the urge to pay Katsuki back for spraying him in the face earlier. Wrestling in the bath really would make a mess, and he was too tired for that much physical labor.
They soaked for another few minutes before Katsuki started complaining about his fingers pruning. Katsuki stood from the bath first, drying himself off and tugging on a worn pair of sweats before assisting Izuku with his still wobbly legs. He helped Izuku into a dry t-shirt and boxers and hefted him up into his arms again.
“Kacchan’s so strong….” Izuku sighed, tracing a finger along the defined lines of his flexed biceps.
“You tryin’ to talk me into round two, Nerd?”
“R-Round two?!” Izuku blanched, “I’m still recovering from the eight orgasms you just forced out of me! I might be limping on my next patrol at this rate….” He sighed morosely. He could already imagine Todoroki’s genuine, well-meant concern and Uraraka’s astounded, knowing stare.
Katsuki abruptly dumped Izuku onto their mattress, “Oh, I’m just gettin’ started, baby.” A cocked, toothy grin spread across Katsuki’s face, and his eyes glinted mischievously. “We’ve got the rest of today and tomorrow off, and I’ve not even touched that other little hole of yours.”
Izuku shuddered. He definitely wasn’t going to be walking tomorrow.
