Chapter Text
Iida's glasses fog up slightly as he nervously adjusts them, his engines whirring faster than usual. Maki leans against the doorframe of their shared apartment, her alien-like eyes narrowing with amusement.
"Let me get this straight," she says, voice dripping with sarcasm, "after all these years of you being a model hero,follows every rule to a T, the one thing that finally makes you stumble is... this?"
Iida vissibly stiffens under her gaze but doesn't back down. His hands clench at his sides.
"It’s not about stumbling! It's about accountability! I want structure,to be corrected when my actions are suboptimal."
A slow smirk curls Maki’s lips as she pushes off the doorframe and steps forward until they're nose-to-nose (or rather, nose-to-chin). She tilts her head mockingly.
"Ohhhh? So if Tenya Iida breaks curfew or forgets to do laundry..."
"Yes."
He cuts in too quickly before clearing his throat and straightening into perfect posture again:
"Hypothetically, yes. If there were grounds for disciplinary action… then it..discipline would be appreciated."
"Then you'd want me to, what? Scold you? Dock your allowance? No dessert for a week?" Maki mocked tapping her blue finger against iidas forehead.
Iida flushes a deep scarlet, his face nearly matching the color of his eyes.
"W-well, perhaps. But I was thinking something more..."
He trails off, not able to bring himself to finish the sentence. It's too embarrassing, too childish.
"Spanking," he whispers.
Maki's eyes widened with an unreadable thought, shock, confusion,amusement?
"Spanking?"
She questioned, her voice coming out blunt and a tad judgmental. Iida's entire body locks up, his engines give a high-pitched whine like a tea kettle left on too long. His glasses are practically steamed over now.
"Yes."He manages, voice strained.
"A-a physically enforced consequence for misconduct. I've researched the benefits! It fosters self-awareness and reinforces boundaries!"
Maki stares at him for one long, deadly second before her lips twitch violently she's either about to laugh or hex him into next week. Maybe both.
"...You," she says slowly,
"want me to bend you over my knee like some naughty school kid who didn't do their homework?" Her expression was one of disbelief as she tried to imagine taking her pro hero boyfriend over my knee for a spanking.
A strangled noise escapes Iida as he fights the urge to cover his face in embarrassment. Meanwhile, Maki’s grin widens, the kind she gets right before she chews out pro heros for fun.
"And you’ve researched this?"
Maki's head tilted slightly as she pondered over the thought of her prudish boyfriend researching being spanked by your partner. Iida nods stiffly, his Adam's apple bobbing. The engines on his legs are practically smoking with embarrassment. He looks like he's seconds away from combusting on the spot.
"The data is rather conclusive," he replies, as if he's giving a report to a superior rather than proposing he be disciplined by his girlfriend.
"It fosters honesty, humility, and trust within the relationship."
He adjusts his glasses, clearly trying to regain some shred of composure.
"And it helps the receiver maintain a sense of accountability."Maki tilted her head up to look iida in the eye, iidas head dipped down to accomdate the height difference, she barely reached eye level with his chin but the blue headed boy couldn't help but feel small under her gaze.
Maki's alien-like eyes narrow, her smirk sharpening as she watches Iida squirm under her scrutiny. The air between them crackles with something dangerous ,amusement? Challenge? Probably a bit of both.
"You," she says slowly, dragging the word out like a blade being unsheathed, "actually researched spanking." The disbelief was evident in her tone.
ida's breath hitches. His hands twitch at his sides,instinctively stiffening into perfect posture even as every other part of him screams to bolt.
"I reviewed scholarly articles on corrective measures in romantic partnerships!"
A beat passes. Maki exhales through her nose, the sound suspiciously close to a laugh stifled by sheer disbelief.
"So what you're telling me is... my boyfriend spent hours reading about getting his ass smacked like some misbehaving toddler?" The words have Iida's face flaming worse than ever. He splutters, struggling to defend and explain himself at the same time. "It's-it's not, that is…!"
He takes a deep breath, straightening his glasses with a shaking hand.
"It isn't comparable to a child's discipline. This is about trust and accountability between two adults. It's a form of physical reinforcement"
Maki holds up a hand, cutting his rambling short."Let me see if I have this right…You ... you want to be spanked to .. have rules and shit , why exactly"
Maki looked up at her boyfriend with a now genuinely curious expression. As far as their sex life went it had been pretty vanilla and now iida was proposing a dynamic that could shift their whole relationship. Iida clears his throat, shifting his weight from foot to foot. It's as though every muscle in his body is trying to resist the gravity of this conversation. His voice drops to a low murmur, the words coming out slowly, like a confession.
"It's… an effective way to manage impulses and… keep myself in check. A way to ensure that my actions align with my ideals. It'll establish boundaries and consequences and…"
He swallows hard. For a moment, he looks so unbearably young.
"It would mean… submitting to you."Maki's eyebrow raised at that, 'submitting', the idea made something swirl in her stomach.
"Ok" She nodded, it was a sharp change from the previous teasing, now a look of determination crossed her features.
The sudden change in demeaner sent iida into a slight panic, he loved his girlfriend but her unpredictability could be terrifying.Iida stared at Maki, disbelief warring with hope. Had she really just agreed so easily? No more teasing or mockery? He almost preferred it when she was laughing at the idea.
For once, he wished for her usual sardonic commentary. Instead, she studied him with a calculating, almost predatory gaze, the way a wolf might look at a cornered mouse.
Iida swallowed, suddenly very aware of their size difference. Maki barely came up to his chin, but in this moment she seemed so much bigger.
"...You're... serious?" His voice is quiet, hesitant,the opposite of his usual confidence.
Maki's mouth quirks in a wry smile. She steps closer, narrowing their proximity until their bodies are almost touching.
"Oh, darling, I'm dead serious."
Iida shudders. She almost never calls him pet names, the only exceptions being when she's making fun of him. He doesn't know what to make of this new tone, this new Maki.
Maki stepped back with an amused glint in her eyes, proud of herself for once again reducing her boyfriend to a blushing mess.
"Send me what you read, i wanna know exactly where your heads at."
She said bluntly and with a dismissive wave of her hand she left the kitchen , disappearing into the apartment. Iida stared after her, mouth agape. He still looked like he'd just survived a villain attack, flushed head to toe and in a daze. He'd expected mockery, not...this.
He snapped out of it with a shake of the head. Right. Research.
He spent the next few hours digging up every article and study he'd bookmarked on the topic, sending them off in one long, neatly organized message to Maki's phone.
---------------------------------------------------------------------
After the discussion in the kitchen maki and iida settled back into their regular routine but now with the added tension cause by a peice of paper neatly stuck to fridge with a panda magnet.
'Iidas rules' written neatly at the top along with a list of basic rules like 'no swearing' , 'do your chores', 'text if your going to be home late', 'no lying'. As the next few days went by, Iida found himself growing impatient. The agreement was made, he'd sent over his research and his proposed list of rules, so why hadn't anything happened yet?
He found himself constantly glancing towards the list of rules, a strange mix of anticipation and anxiety stirring inside him. He wanted, needed her to act. But Maki remained infuriatingly nonchalant, treating him exactly the same as she had before their conversation. This continued on for a week, and then another, and another. Iida knew he was losing his composure. It was getting harder to maintain his stoic demeanor, his patience fraying with every passing day.
It was late one evening, and he was sitting at his desk, trying (and failing) to focus on work when Maki walked in. His heart leapt into his throat, the anticipation palpable. But Maki just strolled into the room like she owned the place, taking a seat on the edge of the desk and swinging her legs lazily. Maki's hands gripped the edge of the desk as she lent forward the action capturing iidas attention.
"I thought we agreed no work after 10pm,"
She spoke casually but now her tone was different, there was no teasing or mockery but in place a deep , dominant aura that sent a shiver down iidas spine. Iida's pen froze mid-stroke, his entire body tensing. He'd been waiting for this moment, but now that it was here he found himself almost paralyzed with a strange mixture of excitement and nervousness.
Slowly, he set his pen down, giving her his full attention. He was all too aware of the way she was perched there, legs swinging casually while she studied him with a predatory gleam in her eyes.
"...I lost track of time," he murmured, the words coming out almost in a whisper.
Maki tsked, an unimpressed sound. She reached out and grabbed his chin, her touch firm but not unkind. She tilted his face up, forcing him to meet her gaze.
"You shouldn't neglect your rest for the sake of paperwork, darling."
Her tone was chiding but there was an undercurrent of satisfaction there, like she was pleased with the effect she was having on him. Iida's eyes widened. He'd never heard her use pet names like that and the way her grip tightened on his chin when he tried to glance away but her grip remained firm.
"Go change into your pajamas and wait for me in the bedroom."
The command was stern and non negotiable, she wasnt asking.Iida's breath hitched, his entire body locking up for a split second before he snapped into motion. His engines whirred as he practically vaulted out of his chair, nearly tripping over himself in his haste.
"Yes ma'am," he blurted, already halfway to the door when he realized how eagerly obedient that sounded. He stiffened mid-step, but Maki’s sharp gaze pinned him in place.
"Go on" she prodded and Iida was moving again like a man possessed, sprinting down the hall toward their bedroom with uncharacteristic speed. Iida burst into the bedroom and quickly began to change into his pajamas. His hands were uncharacteristically shaky as he fumbled with the buttons on his night shirt, his heart pounding in his chest.
He could already feel anticipation coiling tightly in the pit of his stomach. This was really happening.
He finished changing, sitting down on the edge of the bed to wait with trembling legs. His eyes darted around the room, taking in every detail, the shadows in the corner, the soft sheets, the dim light of the lamp on the bedside table creating the perfect atmosphere for the upcoming punishment.
Minutes ticked by, every second feeling like agony. Iida fidgeted with the hem of his shirt, unable to stay still. Just when he was beginning to wonder if Maki was ever going to arrive the bedroom door creaked open, and Iida straightened instantly at the sound.
Maki stepped into the room, closing the door softly behind her. She looked completely calm and collected, a stark contrast to his own anxious energy. Iida couldn't help but notice the gleam in her eyes, the slight smirk tugging at her lips.
Maki sat down on the bed beside iida, the room filled with silent anticipation, she watched iida carefully how his normally rigid posture was slightly slumped, his legs trembled and his hands gripped tightly against his knees.
"Tenya." She spoke despite her normally teasing expression her voice was filled with a cross between caring and dominance.
"Are you ready" the question was daunting, the reality of the situation setting into iidas mind as he realised this was actually happening.
Iida gulped noisily but didn't hesitate,
"Yes ma'am, " standing up stiffly he moved over to Maki's side. He put his hands on his pajama trousers hem, giving his girlfriend a blushing,questioning look. Maki returned it with a firm nod and an evil glint in her eye that made iida give another gulp. He undid the drawstring and dropped his trousers, with another questioning look he held onto the band of his underwear.
"These too", Maki gave another encouraging nod and iida dropped his boxers as well.
Lying over the Maki's lap was no easy task, from the height difference to the fact that iida had significant muscle compared to his girlfriend but she made it work getting iida balanced over her lap woth his legs and torso resting on the bed underneath them.
Iida was facing away from her, his head cradled in his folded arms. Iida's face was hidden from her view but his ears were bright red at their tips and his hands tightly gripped his arms.
Maki took a moment to appreciate the current situation, im their every day life iida often took a more dominant role so maki enjoyed having her boyfriend be in such a submissive position. With Iida lying bare across her legs, the hard muscles of his torso tense with anticipation , his sculpted thighs trembling as he awaited the first swat. She could feel the heat radiating off his skin, he looked vulnerable and nervous and maki couldn't help but love seeing him like this.
Gently, she placed one palm on the small of Iida's back holding him firmly in place, the other rubbing slow, rhythmic circles on the curve of his backside. Her touch was shockingly gentle, but the underlying sense of control was unmistakeable.
Without much warning maki raised her hand and brought down the first smack to iidas pale backside. The sharp crack of Maki's palm against Iida's bare skin echoed through the bedroom. His entire body jerked in surprise, a strangled gasp escaping his lips as he instinctively clenched his fists tighter.
Maki watched with dark amusement as a deep pink blotch bloomed across the afflicted area, the skin pinkened so quick and intense that it practically pulsed under her gaze. She let out an approving hum.
"Good boy," she murmured, "Taking your first spanking so well."
Her hand rubbed soothingly over the reddening spot before raising again for another firm smack, this time slightly harder than the last. Iida let out another strangled sound as the second smack landed, his shoulders tensing at the combination of pain and vulnerability. It stung, and he found himself pressing his forehead deeper into his arms, shifting the tiniest bit against her lap trying to find some relief. He could feel the heat radiating off his backside, every nerve buzzing like a live wire.
Maki's hand rubbed the area soothingly again, tracing lazy figure-eights over the pinked skin with her nails. Iida inhaled shakily, his fingers digging into his arms as anticipation coiled in his chest.
"Why are we here tenya." maki asked continuing to gentle run her nails over the sore cheeks. Iida's breath hitched, his entire body tensing at the question. The nails dragging over his stinging skin made him shiver, the sensation making it hard for him to think.
"Because I broke one of our agreeded upon rules," he answered immediately, voice shaky yet filled with his usual obedience . His hips shifted slightly against her lap as if trying to get away from the painful avhe in his backside.
"i was working past curfew which we agreed i wouldn't to ensure i avoid overworking myself."
Maki hummed in approval before landing another sharp smack on the same spot she’d just soothed, the contrast between pain and comfort making Iida jerk with a quiet gasp.
"And what happens when you break the rules, Tenya?" Maki asked, the hand on his back now gripping his hip with a possessive grasp. Her fingers traced the soft skin, the sharp lines of muscle.
Iida shuddered at the authoritative undertone in her voice, the part of him that craved discipline and control responding with embarrassing eagerness. He wet his lips and answered through gritted teeth,
"I get punished."
Iida's bottom was nearly scarlet now, it having taken a surprisingly short amount of time to reduce Iidas's defences to the point where he was clearly struggling to keep his composure. His whimpers were sincere, damp with the threat of tears, maki heard iida finally cave with a sob at a particularly hearty swat to the very top of his thighs where the skin was stretched taught.
"You're a pro hero baby, rest is important and i wont have you sacrafising that for the sake of paperwork" A strangled cry escaped Iida's lips when the smack landed, the skin stinging at the impact. The pet name and the hint of care had his heart swelling despite the tears that were brimming in his eyes. He desperately tried to hold back the sobs building in his chest, biting into his arm to muffle the noises.
He was a pro hero, dammit, and yet right now he was a trembling mess across his girlfriend's lap, his ass feeling like it was on fire. Maki tightened her grip on the boys hip pulling him closer against her side, she used the position to land some particularly harsh swats to his reddened backside.Iida squirmed, a pitiful whine escaping him as he found himself pulled even harder across her lap. Her grip on him was firm and unyielding, like a steel trap, he was utterly helpless to her whims. And oh god, that thought had him squirming all over.
Each swat to his backside left his skin searing, the sting making his toes curl and his breath catch. Despite the tears streaming from his eyes, he did not ask her to stop, he had asked for this. He just gripped his arms tighter, his body taut with submission.
Maki couldn't help but feel a sense of satisfaction as she watched her normally stoic boyfriend over her lap trembling with tears, his toned backside and thighs quivering red as his feet desperately thumped against the covers.
The spanking came to a slow stop, with maki landing the final swat to the centre of iidas backside, hard enough to make his cheeks clench and his legs kick out.
"Ok tenya, we're done baby you took that very well". Maki spoke softly, far from her usual sardonic teasing as she tried to sooth her boyfriend.
Iida’s entire body shuddered as the final smack landed, his cheeks clenching involuntarily from the sharp sting. A choked sob finally escaped him, his legs kicking out weakly before going back to their position against the comforter. The sudden stop of her hands assult left him breathless and trembling.
For a moment, he just stayed there forehead pressed into the mattress, shoulders shaking with quiet cries , his hair was messy and his glasses discarded on the bed but he had remained obedient and discipline not moving from his position over my lap. But when Maki's voice softened like that , something in his chest , the guilt and anticipation he had been feeling released in a chocked sob.
Maki continued gently rubbing her hand over his reddened bottom, watching as the tension slowly drained from Iida's muscular frame. She felt a strange swell of affection for the trembling hero laid over her lap, a mess of bitten lips and tear-stained eyes , his usual put togetherness completely discarded, he was utterly wrecked but he looked strangely peaceful, and it was all because of her.
She couldn't resist reaching out and running her blue toned fingers through his messy blue hair.
"Shhhh, you did so well. You were so good for me, baby." Maki's voice came out amused but still containing that dominance she watched Iida, usually so composed and proper, sob openly into the pillow. His entire body trembled with overstimulated vulnerability, his backside still a vivid shade of red beneath her palm.
Iida gently pushed himself back from her lap, but instead of standing up like she anticipated iida slid to knees between her legs resting his tear stained face against her thigh.
She let out a slow exhale through her nose before sliding one hand up to cradle the back of his neck. Her touch was firm but gentle as he pressed his forehead against her thigh.
"Easy," she murmured despite the amused expression on her face, "Breathe for me baby." Her other hand stroked down the curve of his upper back and shoulders, following each shuddering breath he took until they synced with hers.Iida's breath caught in his throat as he found himself cradled against her legs, the tears in his eyes starting to subside. The heat of his stinging bottom seemed to meld with the heat of her touch, making his head swim with mixed emotions.
He pressed his face into the soft warmth of her leg, the firm touch of her hand at the nape of his neck grounding him. Slowly, his breathing evened out, the sobs turning into hiccuping gasps.
"Maki" iidas voice came out surprisingly steady as he pulled away, his red eyes were glossy with unshed tears, face flushed and hair sticking to his forehead. The blue haired boy bowed his head, hands pressed into his bare thighs as he kneeled between her legs.
"Thank you for correcting my behaviour in our agreed upon manner"
Maki couldn't help but let out a sound of amusement, it was a mixture between a laugh and a scoff as she used her hand to push his hair back from his forehead.
"Your such a dweeb you know that"
Iida's nose scrunched up at the insult, but there was no real heat in it, there never was especially not when Maki’s fingers were still tangled in his hair like she knew he secretly loved even if he protested every time she messed up his perfectly styled hair.
"T-That's not a proper way to address your" he started automatically before cutting himself off with a wince. His ass throbbed as he shifted slightly on his knees. "...Partner." He finished lamely.
A slow smirk curled Maki’s lips as she watched him struggle between indignation and submission. Her thumb brushed over the tear tracks on his cheeks still damp from earlier tears.
"Yeah yeah, 'proper hero conduct' or whatever," she teased, "But you're my dweeb first."
Iida felt a rush of affection at her words, his irritation dissolving as quickly as it had come. It still stung, being called a 'dweeb' by the woman who just spanked him like a misbehaving child, but he knew there was a teasing affection in her words too, she had been that way since they met in highschool. He could see it in her gaze, in the way her fingers traced over his face and the way that she clearly didnt mind the tears that had seeped into the material of her pajama trousers.
He leaned into her touch, his eyes drifting half-lidded as he inhaled deeply. The scent of her was grounding, her presence a soothing contrast to the stinging heat across his ass, he had asked for this and she very much delivered.
