“For the love of FUCK, Dunce Face,” the wooden spatula clattered into the sink. “it’s not that fucking difficult to cut goddamn carrots!”
Denki flinched, knife stuttering against the cutting board. “I’m sorry dude! I’m trying my best-”
“Katsuki,” Hanta gently interjected. “Would you come taste this sauce and let me know if it’s good enough for the stirfry?”
He glared across the kitchen. “Whatever. I don’t fucking care.”
“Well I just-”
“I already said I didn’t fucking care! Okay!?” He snapped.
“Dude!” Denki put his knife down, maybe a bit harder than he should’ve. “What the hell is your problem?”
“There is no fucking problem!”
“So when the carrots aren’t evenly sliced, it’s all ‘Fuckin’ ‘ell Dunce Face! You’re an idiot sandwich!’ But when Hanta is actively like ‘Hey dude come help me with the sauce,’ you’re all ‘it doesn’t matter nyehnyehnyeh-’ And then! You’re gonna stand there and say there’s no fricken problem!? There’s obviously a problem!”
Mina sat quietly on the couch, glancing up from her phone to look over the counter. Of course there was a problem. With Katsuki there was rarely not a problem. She sent another text off to Eijirou.
“Would you get off my fucking dick!? There’s no fucking problem!”
“Quit yelling at Denki, bro!”
“Quit fucking yelling at me!!”
“You started screaming first, though!”
“I’m not fucking screaming!”
“You totally are, dude!”
“It’s not my fucking fault you fucks can’t throw together a fucking stirfry okay!?”
“That’s why I was asking for help, man-”
“The carrots don’t need to be perfect, okay!”
“You motherfuckers need to-”
“Katsuki!” Mina stood up from the couch, voice stern.
The blond glared at her, hands falling away from where he’d been pulling at his hair.
She slipped her phone into the pocket of her jeans. “My room.”
The three boys stared at her. “The fuck Pinky?”
“My room. Now.”
“You can’t fucking tell me what to-”
She pulled out her phone again, waving it innocently at him. “Oh I can’t?”
His shoulders tensed. “What the hell did you say to him?”
“That’s for me to know, and you to earn.”
“Oh shit-” Denki whispered. “She’s gonna fuck him up.”
“Shut the fuck up!”
“Katsuki.” She stood up straight, placing her hands behind her back. “My room. Now. And if I have to ask a third time-”
“We’re in the middle of making dinner. You wanna do this now?”
“One.”
“Oh fuck off! You can’t be fucking serious.”
“Two.”
Katsuki visibly flushed, “You’re fucking serious?”
“Two and a half-”
“Alright! Quit it with your fucking counting!” He rounded on the other two boys. “Try not to fucking burn the goddamn building down while I’m gone.”
Denki nodded, cheeks flushing.
Hanta rolled his eyes. “No promises.”
“Strip.” Mina pushed him through the door of her room.
“What the fuck? You haven’t even closed the door!”
She stepped through the threshold and slammed the door shut behind her. “Strip.”
His eyes narrowed as he stood up straight, shoulders back, chest out, painting himself in a proud light. “No.”
Mina stared at him blankly. “Color?”
He raised an eyebrow at her, challenging. “Green.”
She pulled out her phone and snapped a picture of him. Sending off a text and leaving the blond standing in the middle of the room, confusion written across his face.
“What are you doing?” He questioned, posture slipping.
“That’s for me to know, and you to earn, bitch.”
He crossed his arms. “You can’t just fucking boss me around.”
Mina took a step closer. “Oh I can’t? Ya know we have tools for naughty little boys who don’t listen to their mommies.” She placed a tender hand on his cheek. “You think there won’t be consequences if you don’t listen?” Her hand trailed past his ear, landing on the back of his head where she tangled her fingers in soft blond strands and then pulled.
Katsuki grunted as his head was pulled back. Mina leaned forward and nibbled on his neck, sucking at the skin, being sure to leave a mark.
“W-what the fuck are you doing?”
Mina pulled back, licking at the beautiful red splotch marring Katsuki’s pale skin. “When you go back downstairs later, I want everyone to know exactly why you’re so well behaved all of a sudden.” She pulled his shirt collar to the side, and bit down on the juncture between his shoulder and neck.
His whine caught in his throat.
Mina’s free hand slid down his side, coming over his thigh to tease at his crotch. She palmed him over his sweats while she sucked on his neck. He finally uncrossed his arms, hands grasping at her waist, looking for purchase.
She pulled back from him with a dark look in her eyes as she once again fished her phone from its pocket. She stepped back, out of his hold and took another picture of the boy.
“What the f-fuck is up with the photos?”
“Didn’t I already tell you? You have to earn the answers, genius.” She rolled her eyes as she pocketed her phone. “Now. I believe I told you twice now to strip.”
“I believe I told you twice now; no.”
“And you’re sure your color is green?”
“You know I’d fucking tell you if it wasn’t.”
Mina nodded as acid bubbled to the surface of her palms. “Do you like that shirt?”
“It’s just a black crewneck. I can get them in packs of four.”
“The sweatpants?”
He paused for a moment. “Yeah… no, I like these ones, hold on.” He shimmied out of the aforementioned sweatpants, folding them quickly and setting them on Mina’s bed. “The boxers don’t matter though, so go wild.”
“Underneath all that bratting you really are just a good boy.”
“Shut the fuck up, bitch.”
Mina stepped closer, encroaching in his space, hand now full with a little puddle of her acid. “Strip, slut.”
“Fucking make me.”
She splashed the acid across his chest with one hand, and grabbed her phone with the other, quickly snapping a picture of the blond while her quirk ate away at his shirt.
He was breathing heavily, eyes half lidded as he stared down at himself. The fabric corroded and flaked away from his skin, his tits peeked out of the tatters hanging over his shoulders.
Mina seized the opportunity, flicking his nipples with her fingers as she rested her forehead on his shoulder. “Feel okay?”
“It’s a b-bit tingly, but in a good way. You did fine.” He rested a hand in her pink curls, pushing his chest against her fingers as she tweaked and pulled and played with his nipples.
“Good.” She kissed his neck. “Wanna make sure I didn’t hurt you.”
“Mina, please-”
“Damn, you really are needy today.”
“Just get on with it already!”
“No way, you remember you’re getting punished, right?”
He whined from the back of his throat. “Fuck me first, and punish me after.”
Mina laughed against his skin. “You know that’s not how that works.” Her hands finally pulled away from his chest to tug at the waistband of his boxers. She shimmied them over his hips and let them pool at the boy's feet, a position she knew he hated.
She unclasped her own jeans and pulled her pants down just enough to free her tentacles.
Above her, Katsuki huffed a frustrated little moan.
“It’s a punishment.” She reiterated.
“Am I not fucking needy enough, already?” He argued.
“Nope!” She popped the ‘p’ as she pressed her clit against his own, letting her tendrils roam over his skin.
Something in her acid, something in his sweat. What had Denki called it? Peppermint chapstick?
Katsuki’s breathing picked up as the chemicals started working, her slick acting like an arousal balm for him and him only.
She swiped a hand along her tentacles before reaching around him.
“M-Mina-” he breathed against her skin, head dropping to her shoulder as she prodded against his ass.
“I know Dynamite. I know.” She soothed him as she pressed a finger inside, slick with her own lube. “Eiji’s been away for a while. I’ve been texting him about you.”
“The pictures?”
“All for him. I know I’m no replacement, but we thought maybe I could help you get out of your head for a bit. Are you okay to try that with me?” She pumped her finger in and out of his ass.
He nodded against her shoulder. “P-please.”
“Awwwh-” She wrapped an arm around him, pulling him closer against her. “I love you Katsuki. I’m gonna do my absolute best.”
“Y-you’re doing fine Mina.” He wrapped his arms around her. “I‘ll let you know if s-something goes wrong.”
She pressed a kiss against his temple. “Thank you, my angel. Then let’s get some toys in you, shall we?”
He moaned against her.
“I’m going to take my sweet sweet time, gonna fill all of your beautiful holes. You’re gonna be squirming before I even get you over my lap for your spanking. You’ve been very bad today haven’t you? I’m gonna bring you to the edge, over and over again. I’m gonna leave you there, frustrated, moaning, maybe even crying for me in that beautiful way of yours.”
She could feel him getting wetter against her wriggling tentacles.
“You like that, don’t you, slut? So fucking insatiable. You don’t get dicked down for two weeks and you turn into a tantrum throwing child. I’m going to have to bring you to my room every night until Eiji gets back, aren’t I? Gonna have you crying over my knee with a plug up your ass until you’re cumming all over yourself. That oughta shut you up. You just need a reminder of who’s in charge here.”
“F-fuck-” his body shivered.
“Don’t move.” Mina pulled away from him, slipping her fingers free and tucking herself back into her pants.
She took a quick picture for Eijirou, and fuck what a picture it was. His shirt was still hanging around him in tatters and threads, chest sticking out through a few holes. His thighs shined with both his and Mina’s slick, boxers bunched down at his feet. The hickies Mina had given him stood out starkly against his skin, and his flush traveled from his cheeks down his neck to his collarbone.
He was gorgeous like this.
Mina just wanted to tear him apart.
But… she had plans. This was a punishment.
She slid open the door of her closet and grabbed her trusty little black box of fun things. She put the box on the edge of her bed and looked Katsuki up and down for a moment, contemplating her next course of action. “Put your hands on your head.”
“What?”
“Put your hands on your head. And hold them there. I want your arms out of the way.”
He eyed her for a moment before hesitantly following her instructions, placing both his hands behind his head for her, standing awkwardly in the middle of her room. Helpless. Humiliated.
She turned back to her toy box and grabbed a dildo first. It was incredibly simple, something she slipped into her harness and used as a strap. It was black, solid, and smooth. A simple curved rod of silicone. Then she grabbed a butt plug, another simple, black, silicone piece with an appropriately flared base.
She held the plug up to his lips. “Suck.”
He diligently obeyed, opening his mouth for her to slide the plug in.
“Get it nice and wet for me,” she hummed as she lowered herself to her knees. “I’m gonna play with this for a moment.” She thumbed over his clit, huffing a derisive laugh when his body jolted under her touch. She held his thigh for balance as she ran the dildo over his cunt. She used the tip of the toy to press against his clit, gently rubbing it in circles.
She pressed against his entrance, slowly sliding the toy inside, relishing in his muffled moan above her. She didn’t press it in far, no. She only gave him the tip, teasing him with her slow movements.
His hips bucked, trying to press against her hand.
“Don’t. Move.” She commanded.
He huffed a breath around his gag.
She continued her ministrations, sliding the toy from his cunt to trace over the inside of his thighs and tease his clit before bringing it back to where he so desperately wanted it.
She stood back up with a smirk on her face. “I have an idea. And you’re not gonna like it.” She pressed the dildo all the way into his cunt with one hand, and with the other she grasped the base of the plug. “Open.” She instructed.
He opened his mouth for her to retrieve the plug. His breath caught in his throat as she pressed harder on the dildo already nestled in his cunt. She held it in place as she lined up the butt plug to his asshole.
He groaned into her ear as she peeked around his side.
She paused. Cruelly.
“Well that won’t do,” She mused. “I’ve only got two hands, but you’ve got three holes.”
“What is your game…” he groaned, voice cracking.
She smirked. “Here, hold this for me.” Mina pulled the dildo from his cunt, bringing the slick covered toy up to his mouth.
The pathetic little childish whine that pulled itself from his throat as he reluctantly opened his mouth for her?? Fuck-
She eagerly fed the dildo between his lips and then stepped away. She glanced back to her box and procured one of her favorite toys. It was a string of 3, thick, kegal beads. And Katsuki loved to pretend to hate them. She quickly lubed up the beads and the butt plug and turned back to her most obedient little sex doll. He was glaring at her, and yet he was still standing there, perfectly still, sucking on his dildo with his hands on his head.
“I love watching you squirm around these,” Mina admitted, rolling the beads around in her lubed up hand. She pressed the first bead against his entrance, gently guiding it inside of him with her finger.
His legs began to quiver as she pushed in the second, hearing it clack against the first one as she pushed them in deeper.
She stepped behind him, lining up the anal plug and the final vaginal bead at the same time. His chest heaved with his whimpers as she carefully pressed both of them in at the same time, feeling the resistance from the opposite toys on the opposite ends.
His whole body shook with the sensations as she soothingly pet over his exposed sides, his hands still on his head despite everything Mina was doing around him. She reached around his side, smoothing a hand across his stomach and flicking at his clit.
He bucked into her touch again.
She only indulged him for a few more blissful seconds before she was pulling away from his crotch, hands traveling up to his nipples again. He moaned and panted as she flicked the little nubs, pulling and twisting and stimulating in every way she could.
She grabbed his tits in her hands and groped at him while he whimpered and adjusted to the sensations.
“I told you, didn’t I?” She breathed into his ear from behind. “I was going to get you squirming before I even laid you across my lap.” She bit another spot on his neck, kissing, and licking, and sucking another hickey into his beautiful porcelain skin.
His knees buckled, and he struggled to control his breathing. She pressed on the plug stuck inside his ass and watched as he faltered under her touch.
She was so drunk on this moment. On the power she had. On the trust she was given.
She reluctantly pulled away from her most perfect boy, and moved her box off the edge of the bed. She sat herself down on the mattress and waved Katsuki over. “You can put your hands down now. Turn this way, love.”
Boxers still wrapped around his ankles, ass plugged up, and cunt filled to his womb, his steps faltered a little clumsily as he tried to turn. Mina had her phone ready to document his humiliation. She really hoped Eijirou would be satiated with all this. She was trying her best to fill two of her boy's requests while they couldn’t be with one another.
She patted her lap. “Time for the main event. Come here.”
He moaned quietly with each step he took, ducking his head down in shame as he lowered himself across her lap.
“Now you’ve been quite mouthy lately.” She grabbed his hair and pulled his head back, taking the dildo sticking out of his mouth and slowly fucking it in and out of his throat. Tears gathered in his eyes as she teased her way around his gag reflex. “I texted all the boys. I asked them what I should use to take you apart. I think fifty hits from each of us should do the trick.”
He whimpered around the toy in his mouth. Face flushing at the thought of all of his partners being involved in his humbling.
“We’re going to start simple though. You can thank Denki.” She let go of the toy and his hair, letting him slouch back down over her lap. Instead her hand came to rest on his ass. She pressed on the plug peeking out between his legs and then moved her attention to the round curve of his ass. She grabbed her phone off the bed and grabbed Eijirou a good before picture. Pale skin, all smooth and pretty and unblemished. She hummed low in her throat, shifting subtly as her own excitement started leaking from her tentacles.
“Fifty warm up swats with just my hand. He’s looking out for you.” She whispered above him. With a gentle rub, and then a teasing pinch, she finally pulled back and got started. Two hits on either side, two hits more a bit lower on his sitspots, then back up again with three hits on each side. Ten.
She followed the same pattern again, a bit harder this time, listening to him choke on his own moans. Twenty.
She landed the next ten in quick succession, all in one spot on the left side of his ass, all as hard as she could safely swing. The next ten after that were repeated on the right side. Fast, hard, and merciless. That got her a whole ass, really for real, squeak from her high and mighty little fuck toy.
She’d learned from Eijirou. To drag it out: scatter the hits, take your time. To prove a point: attack one spot relentlessly. A good session for Katsuki would have a good amount of both.
He wants to enjoy the experience, but he wants to feel it, too.
Forty.
She went back to her original pattern, landing two hits to his ass, two more to his curve, coming back to his ass, and spicing it up with the last four hits landing a bit lower on his sitspots. God she hoped he bruised. He would love that.
“The first set is all out of the way. Consider your ass warmed up.” She ran her hand over his skin while she fumbled for her phone again. She was making progress. His ass was a bit splotchy, pink, and warm to the touch. But they both wanted much more.
She grabbed the base of his plug and slowly began to pull it out. “Hanta wants me to paddle you with my hairbrush,” she began, conversationally, as she pushed the plug back in. “He wants me to focus on your thighs though.” She continued, casually fucking the plug in and out of Katsuki’s ass. “He says he wants you to feel it every time you sit down.”
Katsuki moaned around the dildo, hips shifting with every pull of the buttplug. Mina pressed it back in, tapping on the base, pressing it deep within him, rustling the balls situated on the other side of his walls.
“Are you ready for the next set?” She asked, reaching a hand down to cup his jaw, turning his head towards her. She held his jaw between her thumb, pinky, and ring fingers, and with her index and middle she gently pushed on the base of the dildo, stuffing it deeper into his mouth. “I asked a question. Are you ready for the next set?”
He gurgled an answer around the toy, but Mina wasn’t done fucking with him. “What’s wrong?” She smirked. “Can’t answer?” She pressed it the rest of the way in, relishing in his little gag, watching closely as tears sprung up in his eyes as he choked on her dick once more. Fuck she couldn’t wait to fuck him with it when the punishment was finally done. She let up on the dildo, letting Katsuki ease it halfway back out of his mouth until it rested against the shallow cradle of her fingers.
She grabbed her hairbrush off her bed and ran the bristles across his ass. She trailed down to his thighs, scratching against his flesh along the way. This would take a bit of concentration on her end, but she really wanted to fuck his mouth and spank him at the same time.
She bit her lip in thought for a moment. The anticipation was perfectly fine for Katsuki to sit with while she planned her attack. She didn’t have the coordination to do what she wanted. Maybe… she could just choke him a bit, ten on and ten off. But don’t give him space to realize.
Okay. She got it!
She pressed her fingers against the dildo again, she didn’t hear him swallow around it as she started swinging at his thighs. The pattern was nice and simple this time, and it was going to stay simple. Just alternating hits. One on his right thigh, just underneath his ass, followed by one on the left.
She landed ten hits against his thighs and let up on the dildo, swinging a bit harder for spanks eleven through twenty. Then she pressed on the base of his toy again, this time he somehow wasn’t ready, she felt him convulse and gag around it, but pressed on with her plan, landing the next ten hits as fast as she could so she could let him back up for air.
He stuttered in a breath while the beating continued along the backs of his thighs. He was doing so good.
She was a bit gentler this time, pressing the toy into his throat and finishing off the last ten spanks with all of her might. She really was trying to bruise him, knowing he was praying it would bruise too.
She pulled away from his ass and his jaw, letting him sag over her lap, dead weight sinking towards the floor. She pet his hair gently. “You’re doing such a good job, Katsuki.”
He pressed his head against her hand.
She pulled the dildo out of his mouth, letting him properly catch his breath. “Color?”
“Green-” he rasped. “P-please-”
“Shhhhhhh,” she brought the dildo back up to his lips cooing gently as he obediently sucked it back down.
His ass was reddening up quite nicely, between trying to cover as much as she could during the warm up, and the special attention she’d just given to his thighs, she felt he was ready for Eijirou’s set.
She grabbed the belt from her box of toys. It didn’t used to be in her box of toys, she honestly liked to actually wear it once upon a time. But it was thick, and it was leather, and it snapped so nicely against Katsuki’s skin. It hurt him much more than her hand did. He had cried with it once. The day she got him crying was the day she knew she needed it available during all of their scenes.
“I’m sure you’ll be able to tell…” she rubbed the leather over his ass. She felt his body tense over her lap. He knew. “This is from Eijirou.”
She cracked the belt across both of his asscheeks, going absolutely feral for the noise that tore from his chest. A squeaky little whine that Mina just knew would turn into keening sobs today.
She wasn’t paying attention to where she was hitting.
She wasn’t even counting.
Eijirou said to belt him until he cries.
And she was going to fucking deliver.
The belt cracked against his skin, leaving angry red welts in its wake. Katsuki shivered and shifted with every hit, legs restlessly bouncing as he lifted himself off her lap, pulling away from his punishment.
She didn’t let him, though.
She placed an arm over his back and finally began her mental counter. She’d do twenty more.
She made sure to spread out her hits, a few across his ass, a few cupping his undercurve, and a good few hits landing against his abused thighs. She focused heavily on his curve, though. Aiming to bruise the fuck out of his sit spots. Aiming to remind him, to soothe him, for at least a few days.
The last five hits with the belt, she focused on that spot, swinging as hard as she could, feeling him sob and hiccup underneath her hold.
With that, his ‘fifty’ with the belt, courtesy of Eijirou, was complete.
She placed her belt to the side and immediately placed a hand in his hair, scratching soothingly at his scalp while she tenderly pet his bright red ass. Oh yeah. It would bruise.
“You’re doing so so so well, baby,” she cooed gently. “So good for me. So perfect. So beautiful.”
He wrapped his arms around her leg, hiding his face against her shin.
She gently pried his legs apart and reached between them, easily she found the pull string of the vaginal beads still jostling inside of him. She gently pulled one out, ignoring the moan from the boy laying across her lap. She ran her fingers over the slick coating the bead, and then reached for Katsuki’s clit. He jumped at her touch as she circled his nub, running her fingers gently over his mound, working him up.
She pulled away, enjoying the little sobbing groan she got in response. Instead she went back to the string of the beads, carefully coaxing the second one out of his pussy. She gathered the slick once again and messily slathered it over his clit. She rubbed him off for a moment, feeling the tension in his body as she got him closer and closer to the edge. It didn’t take long at all before she had to pull away.
He screeched in frustration around the dildo still wedged between his teeth.
“Now now,” She tsked. “This is a punishment.”
She grabbed the beads swinging freely from his pussy and gently hid them back in his cunt. “Hold these for me, will you? We still have my fifty spanks.”
He groaned pathetically as Mina joyously patted his ass. She shifted around above him and unplugged her phone charger from the brick on her nightstand. “A few spots are beginning to turn purple!” She teased, running the charging cord lightly over his ass. “You love that don’t you?” She held the ends of her cable and swatted him with the middle. He hissed through his teeth.
“You’ve had a lot of heavy hits,” she breathed as she whipped him again. “I want to give you a few stingy ones.”
He shifted his weight with every hit she landed. She watched the red skin raise with each whip she planted against his abused ass. She did her best to cover the expanse of his skin, landing each set of ten in a different spot on his body. Each side of his ass, then his thighs, back to his ass again.
He properly squirmed under her as she approached the fifty mark. She threw the last five in quick succession across his sit spots and then placed the cord off to the side, hand coming to cup his ass. Heat radiated from his red skin.
“Oh my lord, babes, you are doing so well for me.” She reached around his shoulders and eased him up. She pulled the toy from his mouth and helped him finally kick off his boxers the rest of the way, turning him around to straddle her waist.
He kept his head down, glancing off to the side as he shifted his weight, but Mina could see the tear tracks running along his cheeks. She cradled him in her arms, just holding him for a moment while he caught his breath and settled himself. He rested his forehead against her shoulder, limbs weighing heavily across her body.
“Color, Love?”
“…Green,” he whispered against her skin.
She nodded in response, hands rubbing his back over his ruined shirt. Her hands steadily dipped lower and lower until she was grabbing his ass.
He squirmed against her as she kneaded his skin, pressing into his bruises and rubbing over the welts. Her fingers roamed, pressing against the butt plug and teasing his taint. With his head pressed against her shoulder she could hear all his little moans and whines with each breath he took. Little noises that echoed from where they caught in his throat.
“Are you ready for the next part of your punishment?” She teased a finger around the rim of his asshole, already stretched around the plug.
“D-don’t a-a-ask like I ha-ave a cho-ice-” he grumbled.
Mina’s heart skipped a beat as she brought a hand up to Katsuki’s hair. “Oh god, I love your stutter. Your voice is so shaky.”
“Y-you’ve e-edged me like th-three times a-and sp-spanked m-me two hund-dred. And y-you a-aren’t ex-expecting my voice t-to be shakey-y?” He sassily rasped.
She rolled her eyes at him. “Well I’m gonna edge you again, so don’t feel too sorry for yourself just yet, brat.”
His shoulders dropped, “A-again??” he whined.
“Again,” she nodded, patting his ass again for good measure. “Now sit up straight, I need to get to your tits.”
He groaned in reluctance, but ultimately obeyed, shyly pulling away from her.
She reached over to her box of fun and procured a lovely yellow set of nipple clamps. She reached for his chest, thumbing over one of his buds through the holes in his shirt. “Push your chest out more,” She ordered.
He listened, eyes darting to the side as she pinched and pulled and rubbed and flicked and twisted and probed and stretched and did everything she could to make his nipples stand perky and puffy and proud from his chest.
Once she was satisfied with the little red nubs, she attached the clamps to them, tightening them carefully. “Does this feel okay?” She tugged on the chain experimentally.
He hummed in the back of his throat “‘S fine.”
“Okay good. Then go take a seat at my desk.”
He eyed her warily but didn’t say anything as she lifted him off of her lap. He awkwardly shuffled to her desk, toys brushing and jostling each other within his walls, and then tenderly lowered himself in the chair. He shifted, adjusting to the things inside of him and the pain radiating from his ass.
Mina had snuck a picture of his reddened ass and then stood up from her bed. She shucked off her pants before she grabbed her phone, a lined sheet of paper, and a pen.
She brought the goodies over to Katsuki and laid them out in front of him.
“You’re going to write lines for me,” she chirped.
“Lines?” He glared up at her a bit incredulously.
“Yep!” She smiled. “You’re gonna write, ‘Good sluts ask to be dicked down when they need it,’ twenty times.”
She watched the flush bloom along his cheeks. “Wh-what’s the catch?”
“No catch.” She answered coyly, letting him know that there absolutely was a catch. Well, another catch even besides needing to focus despite all the toys on and in him. His ass was probably really sore too, and she was making him sit on it.
If he was bothered by anything, he didn’t show it as he turned to the paper and picked up her pen.
“Oh! Dynamite! I almost forgot!”
He rolled his eyes. “There it is…”
She turned the chair back away from her desk and stepped out of her panties. “You deserve some attention after all that spanking. Let me sit with you.” She straddled his lap and held her panties up to his face.
He huffed a sigh and opened his mouth for her again, letting her stuff her panties between his teeth. He turned the chair back towards the desk and leaned around her while she rolled her hips against his.
Her little tentacles wriggled as they secreted her arousal all over the inside of his thighs. It was all over her panties too. She hoped it worked on his tongue and his lips.
She could feel him trembling beneath her, body alight with the effects of her quirk. Mina fought back a giggle as she felt Katsuki push against her, searching for more friction. He panted against her as he ground his hips into her chair.
Her tentacles stroked his clit, teasing at his opening and tugging at the string hanging from him, connected to the balls still pressed inside him.
She brought a hand up to his head, stroking his hair and scratching his scalp gently. There was a spot at the nape of his neck that she gave special attention to, watching reverently as his eyes fluttered closed.
“Hey,” she whispered against his ear. “You stopped writing.” She traced a line down his chest until her finger caught on the chain of the nipple clamps. “You know you don’t get to cum until you’re finished with your lines right?” She licked the shell of his ear, delighting in the whole body shiver it earned her.
Her lips trailed down his neck, leaving gentle kisses in her wake until she found a good spot and bit down. He sucked in a sharp breath, but she felt his arm move around her, resuming his task. She continued her assault on his neck, marring his skin with her teeth, as he worked on his writing.
She pulled away from his neck long enough to look down. She spotted the string of the vaginal beads and slid her finger through the loop. “I think for every five minutes you take, I’ll take something away from you.” It was a little difficult to do with the chair in the way, but luckily for her Katsuki was into her games. He very subtly shifted his position for her to slide one of the beads out. “You’d better write fast if you want anything in you for your reward.”
His breath stuttered as he leaned a little further forward, focusing on the paper.
But Mina wasn’t going to let him focus.
She grabbed his chin in her hands and tilted his face up towards hers. She pulled the panties from his mouth and ran a thumb over his lips. “You’re so pretty when you’re not talking.”
She leaned forward and captured his lips in a kiss. She wasted no time in getting their tongues involved, looking to taste herself on his teeth.
She tilted his head back and deepened the kiss. Their teeth clacked a little clumsily while she adjusted to the position.
She licked into his mouth, heart stuttering in her chest when he pressed back against her.
She played his game of push and pull, skin burning with excitement as his hands came to rest on her hips. His hands carefully roamed over her sides, tentatively lifting the sides of her shirt.
She rolled her hips down onto him again, letting her tentacles poke, and prod, and explore, and arouse.
He bucked up against her, chasing the friction. His hands moved from her sides to her thighs, scratching lightly at her skin. Little goose bumps burst to life under his touch.
She moaned softly into his mouth before finally pulling back a little, biting his bottom lip. Her hands found their way to the sides of his face, cupping his jaw, pulling him closer.
He quivered against her as she dove in for another round, easily dominating this time, pushing her tongue down his throat. Her hands roamed over his skin, scratching gently at his arms and over the exposed parts of his chest.
Speaking of…
She kept his mouth busy while she blindly fiddled with the clamps. She freed his nipples from their hold only to replace the clamps’ torment with her own, rolling the buds between her fingers and pulling at his chest.
She slowly broke their kiss, pulling away and licking her lips with a smirk. “That was another five minutes.”
He panted up at her “I hate you.”
“Less hating, more writing,” she giggled softly as she dropped her head to his shoulder. “How many have you written so far?”
“Fucking… three.”
“Only three!?” She groaned.
“What the hell did you expect me to have!?” He glared up at her. “The whole time you’ve just been ma-MMPH!”
She smooshed their faces together again, swallowing his complaint. She nibbled over his lip again and then pulled back.
“…making out with me.” He finished weakly.
“I don’t want your excuses. I want your twenty lines!”
“Then get the fuck off of me.”
“No,” she stated simply, dropping her head back onto his shoulder. She idly waved a hand behind her towards the desk; “Finish your little paper already.”
He sighed and then picked up the pen, quickly starting to write his lines before she decided to interrupt again.
But- Mina let him work this time, only nibbling gently on his collar bone whilst he shifted beneath her. One hand idly trailed over his chest, weaving between the holes in his shirt, the other tugged lightly at his hair. She pet him gently as he worked, glancing over at the clock on her nightstand every so often, waiting patiently for her five minutes to pass.
She didn’t say anything to him, she just trailed her hand lower and hooked her finger through the loop of the vaginal beads.
Katsuki didn’t acknowledge it either; he just lifted his hips for her to slide the next one out.
“How’s the slick holding up?” She inquired, snuggling up against him.
He shrugged, “Starting to wear off.”
“Want another dose?”
He huffed a small, incredulous laugh. “Like I even get a choice.”
She nibbled on his ear. “Oh, but you do get a choice. I’ll let you finish these lines, get you off, and let you leave.” He shivered against her as she whispered. “Or… I’ll keep playing with you, I’ll edge you again, torture you some more, and then I’ll lay you on my bed, spread your knees apart, and fuck you until you’re crying again. I’ll even spank you some more if you ask nicely.”
His breath hitched as she licked into his ear.
“What’s it gonna be, baby boy? Are you done for the day? Or are you going to beg me to fuck you like the depraved, needy little slut you really are.”
His pupils dilated, though he kept his gaze focused on the desk. On the words she forced him to write.
Good sluts ask to be dicked down when they need it.
“Well, Katsuki?” She trailed a finger up his chest, under his chin, tilting him towards her.
“…Do it. Please.”
“Do what, my little angel?”
“Keep going.”
She tenderly brushed his hair away from his face. “You want me to edge you again?”
“Fuck Mina- I want you to wreck me. Rile me up, spank me again, tie me to the bed and rail me into the mattress until I pass out, I don’t know, just please-”
She cut him off with another kiss, gently pressing her body against his. Her tentacles writhed against him, once again depositing their slick against his skin, leaving in their wake a trail of tingling nerves and insatiable warmth.
She slipped her finger through the loop of the beads again and pulled out the last one, letting her tentacles take its place, dipping into Katsuki’s dripping cunt.
His thighs quivered and tensed underneath her. How she wished to reward him for saying such fucking delectable things to her.
But…
This was still a punishment. Wasn’t it?
Her tentacles slowed to a stop as she pulled away from their kiss. His eyes stayed closed as his chest heaved for air.
“Thank you, Mistress.”
Heat rushed through her body.
“W-what?”
His eyes slid open curiously, then a smirk pulled at his lips.
She could see him filing away her reaction for later. Bitch-
He schooled his features back into a neutral position. “Move. I have to finish these fuckass lines so I can get my ass decimated.”
“Don’t try to play the fucking power bottom with me!”
“You’re gonna be fucking the power bottom.”
“No! There is no power in this bottom!”
“This bottom can fit so much power.”
“Katsuki!”
“Yes, Mistress?”
Mina felt the heat in her cheeks. “No! Enough of that!” She stood up from his lap. “Stand your ass up! You’ve lost sitting privileges. You wanna get spanked some more? I’ll fucking film it for Eiji.”
“Oh no.” He sassed as he stood up and kicked her chair to the side. “Not more spanks. That’d be awful.”
“You’re such a masochist-”
“Mina.” He grabbed her hand. “Green.”
She paused for a moment to actually register his check in, then squeezed his hand reassuringly, “I hear you, Dynamite. I’ll get you out of your head.” She pressed a gentle kiss to his cheek and pulled away. “Now finish your fucking lines you goddamn slut.”
Her hands pooled with a muted kind of acid, something she hoped would sting, maybe burn a little, but not damage or hurt.
Katsuki stuck his ass out as he leaned over her desk to finish his lines. Mina poured the viscous liquid over his ass.
The boy gasped at the sensation. “Holy fuck- what-!?”
“It’s my quirk. Is it okay? Too much?”
“Oh my fuck-” he breathed.
“Good or bad?”
“Good- oh my fucking god- good-”
Emboldened by his moans, she cupped his ass and began rubbing the liquid into his skin, spreading it over all the red splotches and bruises. “Tell me about it?”
“I-it’s… like a muscle pain reliever. It’s s-so warm- it burns. But it f-feels so good.” He whined from the back of his throat. “F-fuck it’s- it’s getting tingly- like when y-you rub against m-my- nnhn-”
“Keep writing. Okay? I’ll be back.” She pressed a kiss to the small of his back and then ducked into her closet, grabbing her usual aftercare towels.
She slipped her jeans back on, not bothering with any underwear, knowing she’d just be taking them right off. With that, she headed to the bathroom at the end of the hallway.
She wet down a couple of hand towels, rung them out, and sped back towards her room.
Oh gods- what a sight her boyfriend was.
He was panting over her desk, back arched beautifully, ass out, and all hers.
She needed to fuck him.
“Did you finish yet?”
He turned towards her, face flushed. “Six left.”
“What a shame…” she shook her head disappointedly as she stalked around behind him. “Then this has to go.” She tugged on the butt plug.
Katsuki whined as she pulled it out and placed it off to the side with the beads.
“How are you feeling?” She ran her hands over his ass, still warm to the touch.
“Empty…” he admitted.
“What?” She blinked.
“What?” He peered over his shoulder.
“How does this make your ass feel empty?”
His face flushed red. “Oh! You meant the- Oh… um- Yeah, it’s still warm and tingly and really hot.”
Mina snickered, then dissolved into giggles. “Did you think I was walking about the plug?”
“How the fuck was I supposed to know!?”
“Quit talking to me and finish your lines! I wanna fuck you, but you’re taking so long.”
“How the hell is any of this my fault you fucking harpy??”
She spanked him. “Do not get mouthy with me, I haven’t googled how to safely wash a mouth out with soap but don’t you dare think I won’t figure it out for you.”
“Cunt, bitch, whore, bastard, mother fucker, prick, asshole-”
She yanked his hair, “I swear you men will do anything but go to therapy. Finish your lines, you goddamn masochist.”
He moaned deep in his throat as he directed his focus back to the paper on her desk.
In the meantime Mina pinched at his ass, watching his legs shift under her touch. She scratched lightly over his skin, aggravating it more. Idly she grabbed her charging cord again, running the wire down his thighs before swatting at him, drinking in his hisses of pain.
He stood up, straightening his back out as he picked up the slip of paper. “Here. Twenty.”
“Finally!” She yanked the paper from his hand and balled it up, tossing it behind her.
“Oi!” Katsuki balked. “What the fuck did I write all that shit for if you’re not even going to-”
“Do you wanna write them all again?” She threatened.
He sealed his mouth shut, shaking his head in response.
“Good! Cause I can’t wait any longer.” She stepped into his space, pushing him against the desk. Her hand went right to his cunt, stuffing two fingers immediately inside.
“Ah! Wait! I’m-”
She pressed her body against his. “Don’t worry, I’m not finished with you yet. Cum, baby.”
“M-Mina-” he breathed, an arm wrapped around her shoulders, pulling her closer.
“I’m gonna fuck you on my fingers. Then I’m gonna lay you out on my bed. I’m gonna plug you back up for me, get you nice and full and aching. Then I’m gonna choke you on my cock, make you lube it up for me, and then I’m gonna fuck you with it.”
His legs shook underneath him.
“You like that, baby?” She giggled, forehead dropping to his shoulder as she pumped her fingers deeper, faster. “I’m gonna fuck you over and over again. Gonna make you cum on my fingers and my cock and my clit. I’m gonna make you squirt. And I’m not gonna stop. And tomorrow? We’ll do it all again. I’ll invite the boys too, let Denki and Hanta take turns putting you in your place while you wait for Eijirou to come back home.”
He squeezed her tightly as his muscles trembled. He was close.
“And Eiji? He knows all about what you’ve been doing. How you’ve been acting. He’s gonna want a turn punishing you too. Maybe I’ll tell him about all those names you called me. Maybe he’ll let me watch. Would you like that, Katsuki? I’ll have Eijirou beat your ass red while I wash your mouth out with soap. Baby you’d be such a mess.”
His breath caught in his throat as his walls spasmed around her fingers. His hips bucked into her hand and his head fell back, mouth agape in a silent scream as he came into her hand.
She worked him through it, feeling his fingers tense on her shoulder.
“That’s a good boy. Cumming so nicely for me.” Slowly she freed her fingers from his heat. “Shirt off, get on the bed.”
He panted heavily as he forced his boneless body to move. He struggled for a moment with his shirt, having a difficult time getting out of it with all the holes, but soon enough he was finally, finally naked, and sitting himself on her bed.
“So obedient for me.” She praised, carding her fingers through his hair. “How would you like your reward, my love?”
He sucked in a stuttering breath, “The s-strap. P-please. So e-empty-”
“Yes, sir.” She pet his hair. “Roll over, hands and knees. I wanna be able to spank you too.”
He rolled over for her while she took her harness from the box. She grabbed the dildo and set it on the bed in front of him. “Lube this for me?” She asked coyly, watching intently as he sucked it down. She bit her lip as she situated the harness over her hips.
She knelt behind him on the bed, giving his ass a big slap before reaching over his shoulder. “Times up, slut.”
He relaxed his arms, sinking into the bed, arching his back beautifully and presenting his ass to her.
She slotted the dildo into the harness and then spread his legs, rubbing the tip against his taint for a moment before finding his entrance.
She pushed her way in, basking in his moans while she slowly bottomed out. He was loose, and wet, and eager to please. It wasn’t everyday she got a comfortable Katsuki in her bed, usually there were a lot of ‘this needs more lube’ and ‘my cunt needs a break, try something else’ and various other yellow lights that were thrown for various reasons.
Today though? He was shaking his hips, pressing back against her thrusts, honestly he was fucking riding her strap. All that foreplay must’ve helped.
She grabbed his hair as she rocked against him, listening to his beautiful little grunt. God he was so gorgeous, so pliant.
He tilted his head to the side and closed his eyes, relaxing to the rhythm of Mina’s thrusts. Enjoying his reward. She tried to keep her pace steady for him, letting him enjoy it for a while.
He had just cum after all, this was a little refractory period.
Mina trailed her fingers over his skin, lightly scratching, and tickling, and teasing at his sides, shoulders, and along his back. Little goosebumps rose along his skin in her wake.
She knew how to work him up again, how to draw patterns over his pelvis, how to scratch over the inside of his thighs, how to nibble on his neck, how to tug on his chest, how to lick in his ear.
She used all of her little tricks, all of the little sensations she knew he liked.
It wasn’t much longer after she started her targeted attack that the blond was whining underneath her, suddenly no longer content to take his fucking lying down.
“M-M-Mina-” he moaned through her thrusts. “Fuck- p-please- Mistress-”
She grabbed his hips and slammed into him a bit harder, ramming her pelvis against his ass.
“I- I n-need-”
“Use your fingers, baby boy. Can you touch yourself for me?”
He nodded, with a small moan, and shifted underneath her.
She kept up her fast pace, fucking him with all her might as he chased after his release.
He bit down on her pillow as his whole body tensed underneath her. She didn’t dare stop as his pussy fought to keep the dildo in, clenching down around it.
It wasn’t until his chest heaved with a gasp, and his legs gave out from underneath him that she finally stopped.
She laid her weight down on top of him, gently pressing him deeper into her mattress. Keeping him steady, keeping him grounded, as he came down from his high.
Her hand tangled in his hair, smoothing it back from his sweat slick forehead.
She pressed a kiss to his cheek and snuggled against him. Just existing with him.
His body moved with every gasp as he worked to control his breathing, coming down from his orgasm like he had been running.
She stroked his hair and shushed him gently, soothingly squeezing his bicep, wrapping her legs around him. She was still inside of him, but they would take care of that in a moment.
“How are you feeling, Dynamite?” She brushed a thumb over his jaw, gently turning his head.
He groggily blinked his eyes open. “Good.”
“Feeling better?”
“… much better,” he admitted.
A smile pulled at her lips. She buried her face in his neck. “Good! I’m glad that worked out! I’ll be back okay?”
He grumbled something back to her in response as she unclasped the harness from around her legs. She shimmied out of the straps, leaving the dildo still nestled inside Katsuki.
She collected the other toys they had used and piled them up on one of her towels, she’d go wash them all down in a moment.
Right now she needed to find…
Ah! There it was; her lotion.
She popped open the cap and carefully squeezed some of the cream out onto Katsuki’s damaged ass. He hissed in a small breath, but ultimately relaxed into the mattress while she worked the lotion into his skin.
“Is this okay?”
He groaned, “more than okay, Queenie.”
Her hands paused in their ministrations, eyes wandering away from him. “Can you… um… can you say the other thing again?”
“Other thing?”
From the corner of her eye she saw him look over his shoulder, peering up at her while she stared off.
She cast her gaze back his way a bit shyly. She saw the moment he understood, eyes widening just the smallest amount and smirk tugging at the corner of his lips.
He pushed his ass back against her hands. “Mistress, don’t stop.”
A wave of heat crashed over her at his words. She picked up where she’d left off, working her lotion into his bruised ass.
He hummed contentedly, and his eyes slid shut.
She teasingly grabbed the dildo again, easing it back into him from where it had been sliding out.
“Mistress-” he whined, voice going straight to her tentacles.
“Hold on baby, I’ve gotta grab my phone, I forgot to take more pictures for Eiji.”
He groaned as her heat pulled away from him, though he waited on the bed patiently for her to snap a few good pictures of his fucked out face and marred up skin.
“Katsuki,” she kneeled on the floor next to her bed, leaning in close to him. He always looked so innocent with his eyes closed, face finally relaxed. “How are you feeling? Did you wanna stop or keep going?”
He held his hand between the two of them, Mina happily slotted their fingers together, grinning widely at him as she snuggled further against the mattress, heart so full of love for her precious boyfriend.
His eyes opened just enough for her to see his pupils, still wide and wanting.
“I wanna do you, but I don’t wanna move.”
A little chuckle ripped itself from Mina’s chest. “Oh my gosh? You’re adorable.”
“‘M cold.” He rolled over, properly facing her and patting the space on the bed next to him. “Lay with me for a bit and then I’ll suck you off.”
Heat rose to her cheeks. “Fuck me, you can’t just say things like that!”
“Say what, mistress? That now that you’re done working on Eijirou’s behalf I wanna fuck you the way we normally do? That I want you to kiss me until I can’t breathe while you scissor me? That I want to choke on your tentacles when you sit on my face? What is it I can’t say? You have to be more specific.”
She scrambled onto the bed, wrapping her arms tightly around the blond, tangling their legs together. She found the base of the dildo with her thigh and gently pressed up, once again easing it in from where it was slipping out. He hissed in a breath and buried his head against her chest.
Her hand rested against the back of his head as she snuggled deeper into the bed with him. “So? What did you think? Was everything okay?”
He nodded against her chest. “It was fine. I had fun.”
She squeezed him tighter. “I didn’t hurt you at all?”
“Not more than I wanted to be hurt,” he shrugged.
She pressed a kiss to the top of his head. “Good… Oh, did you wanna look at the pictures before I send them to Eiji?”
“You hadn’t been sending them as you were taking them?”
She shook her head, “I wanted you to be able to delete any you didn’t like.”
“Fuck, I don’t know if I wanna see them-”
“That’s valid, a couple of them may be a bit dysphoric to be fair, though may I go on record saying that to me, they’re easily all so fucking hot. You should at least see what your ass looks like right now.”
“Oh fuck…” He shifted a little, subtly leaning closer and just barely grinding his cunt against her leg. She pressed her thigh back against him in response, enjoying the little hitch in his breath.
She pulled up one of the ass centric photos she had just taken, after she’d lotioned him up. She turned the phone to him and watched his face heat up at the sight. His legs shifted and Mina felt a spot of wetness drip onto the leg she had propped against his pussy.
“Fuck me…” he breathed.
“Just did,” she sassed.
“Send them to Ei, please-”
She pressed a kiss to his forehead, he kissed her back on her collarbone. “I’ll send these to Eiji now, and when he responds, I’ll read it to you.”
Katsuki moaned as his hips shifted yet again.
Mina’s hand tangled in his hair. “It feels like my little boy is all ready for round three.”
“I’m sorry-” he panted. “I don't know why I’m so hor-”
She cut him off with a kiss, tilting his head back and licking into his mouth. He moaned against her, grinding his hips onto her leg.
She pulled away gently, pressing their foreheads together. “I’m really happy that I get to have you both as Eiji and myself today. Dynamite, you’ve had a hellish month. I’m just really glad you’re finally taking the time to relax a little.”
He didn’t respond verbally, but he pressed himself closer against her chest, squeezing her a bit tighter in silent thanks.
“You know, even Denki and Hanta would be more than willing to help out when you need to decompress.”
“They don’t top as well as you do,” he answered without missing a beat.
“Oh?” She tried to sound casual but there was no way to keep the absolute pride out of her voice. “Maybe I’ll have to host a demonstration. I’ll strip you down, shut you up, tie you to my chair, and show the others exactly how I take you apart.”
He trembled against her, breath stuttering from his chest.
“You’d love that, wouldn’t you? Everyone’s eyes all on you while I rip apart your pride, piece by piece.”
“P-please…”
“Please what, slut?”
“Please, Mistress-”
