"Kacchaaaaaaan, c'mon, be a bro," 17 year old Denki Kaminari whined, just barely stopping himself from hanging off of a freshly ironed t-shirt for fear of death or dismemberment.

"Fuck OFF, Dunce Face," Bakugou snapped from where he was styling his hair in the mirror.

Or trying to, at least.

"You know I have a date with Kirishima today, I'm not going all the way to my house to get your stupid game!"

"YOU'RE the one who left it there!"

"And YOU'RE the one who wants it! Suck my ass, I'm not going!"

Denki groaned even louder, hanging off the edge of the other male's neatly made bed. "Why are you such a dick, bro?"

"Fuck you, and get out! I'm leaving!"

The blond pouted but did as ordered, huffing and groaning the entire way until something lightly hit the back of his head.

He glanced behind him just in time to catch a pair of keys dropping to the floor.

"There, you whiny bitch," Bakugou snapped, already heading down the hall to the elevator. "Those are the keys to my house. No one should be there right now. Go in, get the damn game, and get out."

Denki could have cried, clutching the keys to his chest with a bright grin. "Bro! You do care!"

"Shut the fuck up! And make sure you lock the damn door when you leave," the blond yelled back just as the elevator doors slid closed.

(My last time in 2019 of me saying QRT the entire thread with your thoughts and horny comments. Excuse me while I sob.)

Denki was humming as he took the stairs two at a time to Bakugou's apartment. He couldn't wait to root around all of his draws and be nosy.

"So if this apartment is Midoriya's and Kacchan lives next door then this..." Denki muttered to himself, slipping the key into the lock.

Success!

Denki whooped softly as he let himself in, shutting the door with a soft thud and dropping his bag to the floor.

It was...pretty neat.

Denki whistled low as he turned in a slow circle, golden eyes taking in every bit of information they could.

It was a pretty standard apartment to be honest. Mainstream if you will, with the standard living room dining room set up and small walk in kitchen with a hallway leading to the bedrooms and bathrooms.

But the way it was furnished made it seem chic and hip.

Beautiful hues and colors all mixed together, giving it a prestigious kind of air while also still managing to be homey at the same time.

"Holy shit, these parents know how to /decorate/," Denki whispered to himself...

...Right before he was slammed up against the wall.

"The fuck are you doing in my house, you little brat?!" A female voice snapped.

Denki choked, his hands flying up to yank at the arm pressed against his neck as his feet kicked out where they were dangling in the air, holy SHIT this lady was strong???

His panicked eyes were bugging out of his head as they landed on a...surprisingly young face?

She was terrifying, her lips pulled back over surprisingly sharp canines as she glared down at him with red eyes, slamming him up against the wall again when he didn't answer.

"Who are you?! The fuck are you doing here?!"

He wheezes, black spots dancing across his eyes as he digs frantically into his pocket and grabs Bakugou's keys to present to her fierce gaze.

"Friend, friend!" He gasps out.

Her eyes light up with recognition and she drops him.

He goes down like a rock, coughing harshly as he fights to properly breathe again.

"Fucking Christ, you are strong," he wheezes.

"Watch your fucking mouth," she shoots back, crossing her arms underneath her...

Denki blanks out, his eyes suddenly locked on perky breasts.

He misses her second question and her third.

However, he has /no/ problem missing the way she smacks the back of his head, savagely bringing him back to his current predicament.

"Ouch!"

"'Ouch'," she mocks, cocking a hip out as she frowns down at him.

"Answer the damn question, brat! What are you doing here? And why do you have Katsuki's keys?"

He pouts, rubbing the back of his sore head as he stands. "He gave them to me. I let him borrow my Nintendo Switch over break, but he forgot one of my games. I'm just here to get it."

She squints suspiciously. "No one in your house ever taught you to knock?"

"He said you wouldn't be home!"

She scoffs, pointing a manicured finger at him as she steps into the kitchen.

"Don't move, I'm calling him."

"Yes, ma'am."

She's grumbling as she digs through a purse sitting on the table, pulling out a cellphone and dialing a number.

"Oi! You fucking brat, you don't know how to text?"

He's more than used to tuning out the yelling of a Bakugou, so he let's his mind wander.

And it wanders right to checking her out.

She's sexy as all hell, now that he's getting a better look at her. Slim, with a little bit of muscle around her legs, thighs, and upper arms. She's also tanned, in a way that Katsuki could never hope to achieve with his pale skin tone.

She must have been doing some kind of work out because she's just the tiniest bit sweaty, if her moist tank top is anything to go by.

And speaking of, holy SHIT how is that thing holding those titties back? It looks like it's gonna rip apart if she so much as inhales too deeply.

And her shorts are almost non-existent, cutting off at her upper UPPER thigh just underneath her ass and hugging her curves in all of the right places.

He shifts on one foot, swallowing quietly as his dick starts to harden in his boxers.

Just a little bit.

He's so focused on checking her out that he doesn't notice the fact that she's off the phone, eyeing him as he devours her hungrily with his eyes, a small smirk tugging at her lips.

That's interesting...

He snaps out of it when she slams her phone onto the table with a sigh.

"Alright brat, you're off the hook. Katsuki vouched for you," she says, only a little bit friendlier than before. "I'm sorry about smacking you around like that. You scared me, though. It's not easy being a defenseless woman like myself, you know."

"Yes, I'm sure that must be awful for you," he responds just a little bit sarcastically.

Her eyes narrow, but she still smiles. "Well, whatever. That's in the past. I'm Bakugou Mitsuki. It's nice to meet you."

"Kaminari Denki," he says, waving a shy hand.

"It's nice to meet you, too. Although I never heard of Bakugou having an older sister before."

She blinks, looking shocked, right before bursting in to loud, guffawing laughter.

He flushes brightly, embarrassed for reasons he can't put his finger on.

"What?? You are Bakugou's older sister, aren't you?!"

With one last hoot of laughter, she collapses back into a chair, grinning at him in a way that makes him afraid but also makes him ridiculously aroused. And the way he can see a glimpse of plump pussy lips between her legs...

Yeah, that's /definitely/ not helping.

"Something like that," Mitsuki finally answers with a sigh, tugging her hair out of its high bun to rain in golden, sweaty waves down her shoulders.

Fucking Christ, he's gonna pop the biggest boner known to man if he stays any longer.

"I'm just gonna go grab my game," he yells a little louder than intended, backing quickly out of the kitchen and down the hall.

"At the end of the hall!" She calls.

And really, even without that, he could have guessed it from the black spray painted "FUCK OFF" on the door.

He feel like he has to sneak in, even though he knows there's no one in there.

It's dark, which means that he can see the glow in the dark skull and crossbones stickers plastered all across the walls, shining dully as he fumbles for the light.

And when he does...

"Holy shit, Katsuki you fucking nerd," he hisses, shocked eyes taking in an All Might collection that could possibly rival Midoriya's. Action figures, comics, oldie movies, even an All Might night stand, upon which his game was sitting.

He snags it after taking a couple of pictures to use for later blackmail, slipping the small cartridge into his back pocket as he swings the door shut behind him.

He wanders back into the kitchen, rubbing an arm as he shyly grins.

"Hey, I'm uh...gonna head out..."

He trails off when he catches the spread of sandwiches and drinks on the table, his stomach growling so loud it might as well have sentient thought.

Mitsuki cocks an eyebrow in amusement. "Seems like you might need a snack before you go," she comments dryly.

"...I could eat..."

"Well, brat, help yourself. I'm gonna see if there's any sandwich spread in the fridge."

He bolts forward eagerly, sitting down at one of the chairs while at the same time grabbing one of the turkey sliders to pop into his mouth.

It tastes like heaven.

He almost weeps as the taste of fresh, delicately seasoned meat spreads across his tongue, complimented by crisp lettuce and tomato with a hint of mayonnaise.

Did all the Bakugou's have this kind of cooking skill??

He turns around to ask, and promptly chokes.

Mitsuki is bent over in front of the open fridge door, gently rattling the contents in search of sandwich spears, but all Denki could focus on was her round, full ass swaying gently from side to side.

The soft mound of her cunt peeking out through those obscenely short shorts.

He wants to bury he's face there and die.

"Do you wanna taste this?"

"God, yes," he murmurs softly, before mentally slapping himself to attention. "I mean, try what?"

She stands, holding a bottle of something or another in her hand. "This spread. I'm not sure how good it it."

"But Katsuki seems to enjoy it."

Denki cringes, remembering the last time he tastes a food that Katsuki liked. "No thanks. If I know anything about Katsuki's tastes, that's death in a plastic jar."

Mitsuki laughs heartily. "Well, that's probably true."

She places it back in the fridge and pulls out a regular bottle of sandwich spread before making her way over to the table.

"I hope you enjoy them. Katsuki's father makes them a particular was that no one to this day has been able to replicate. Its magical," she says.

Denki is on his fourth one already, and reaching for a fifth. "Oh, it's definitely magical. Either that, or cocaine."

Mitsuki hoots loudly, and Denki has to struggle to survive when she whacks him on his back in her mirth. "Isn't that the truth?"

She reaches for her own sandwich while the blond chugs an entire glass of lemonade desperately.

"So, Kaminari, was it? Tell me about Katsuki in a classroom setting."

He hums, thoughtfully chewing on his bite. "Well...he's definitely someone you have to get used to."

"Obviously," she says around her own mouthful.

"He's loud and definitely angry, and has a habit of exploding people, mostly me, when he's frustrated."

"Sounds like him."

"But he's also really chill."

Mitsuki raised a skeptical eyebrow.

"No, honest! Once you get past his many layers of anger, aggression, and contempt, he's really awesome to be around. And he takes care of all of us in little ways that make a big difference."

As he speaks, he watches the doubt fall from her face, replaced by a soft smile.

"And man, dating Kirishima-!"

"/Dating/?!"

He yelps as the entire pitcher of lemonade splashes over him, soaking his entire outfit in wet, sticky juice.

"Oh my goodness!"

And then Mitsuki is there with a handful of napkins, frantically dabbing at his stomach and crotch.

And NO, penis, this is NOT the time!

"It's fine," he yells almost hysterically, pushing her hands away just as frantically as she's trying to keep them where they are.

"Don't be ridiculous," she snapped, rubbing vigorously at his thighs in a way that made him tremble.

"You're soaked in lemonade!"

"I can just go back to the dorms and change, it's fine!" He said, praying to every god imaginable that she wouldn't notice how high and breathy his voice had suddenly gotten.

With an angry curse, she tossed the napkins to the table and stood.

"No way. It's cold as balls out there, you'll catch the flu. Just...shower here for now. I'll throw your clothes in the wash and you can stay until they're dry."

"That sounds fine! That sounds great! I'm gonna do that right now," he said enthusiastically, bolting for the hall.

He didn't notice the way her eyes followed him out of the room, gleaming with satisfaction.

(Welcome to 2020, where I still have to tell y'all to QRT the thread with your horny thoughts so I can have the motivation to keep writing.)

When Denki exits the shower (after a really quick hand to meat conversation) he finds nothing in the bathroom except for an extremely small bath towel, folded neatly on the sink.

Like /extremely/ small.

It barely covered his junk.

"Um, ma'am?" He calls nervously into the hallway.

"Here, in the bedroom!" Is what she calls back.

Well, alright then.

He shuffles awkwardly out of the bathroom, shivering as the cool air envelopes his still damp skin.

"M-ma'am I don't think this towel is big enough..."

He tries to think of the most unsexy thought he can in order to keep his dick down enough for him to push open the door.

But all of it comes roaring back when he sees the woman spread out naked against the sheets, little blond pubes glistening in the afternoon sunlight.

He squeaks.

"You know, in retrospect, it was probably useless to send you to the shower," she said, standing fluidly and walking over to him to run an absurdly warm hand down his chest. "But it was the only way to get you naked without seeming /too/ sneaky."

Denki shudders, a small 'eep' slipping out of his mouth as he stumbles back against the wall, overwhemled by the sheer amount of breast suddenly being shoved in his face.

"Y-you did that on purpose?!"

She snorted. "Of course, I did. As if I /don't/ know about Kirishima."

"Katsuki can't keep a secret like that from me. I knew it the first time he brought him over."

As she was talking, her hands continued to wander, one on either side of his body until they were gripping his hips firmly.

"U-um, ma'am, wait-!" he pleaded a little desperately.

She just chuckled at him, yanking him forward against her (naked, holy shit, so fucking naked) body. "You're telling me to stop, but you've been eyeing me up all day. Don't think I haven't noticed."

He whimpered, unable to stop himself from rutting against her thigh.

"Look at that. Even while begging me to stop, you're asking for more of it," she cooed, gently gripping his chin and guiding his mouth to one of her erect nipples.

And really, at this point he isn't fooling anyone but himself.

He latches on with a pathetic moan.

Now, he's 17 years old, and he lives in a dorm with other 17 year olds. He's not a virgin by any means. As a matter of fact, him and Mina have a pretty cool friends with benefits thing going on.

But right now, he feels like he's way out of his element.

Mina is still a teenager, unsure of what she likes and dislikes.

Mitsuki is a grown woman, and she /knows/ what she likes, if the was she murmurs directions at him is any indication.

"Suck gently, baby," she murmurs softly, tugging at the hair at the nape of his neck.

He shudders and gentles his sucking, whining softly as he grinds his erection against her leg, desperate for the friction it provides.

"What a good boy. So eager," she says, and just the soft, pleased voice she uses has something hot and hungry boiling in his gut.

Fuck, this is /nothing/ like when Mina tries to do.

He reaches for her breasts, moaning loudly when he can't even hold all of them in both of his greedy hands.

"Cheeky brat," she huffs, but it's amused and somewhat fond as she pushes his hands and then his mouth away.

"No, wait," he whines, reaching for her, already breathless even though she hasn't done anything.

"Bad," she says firmly, her hand becoming tight and punishing where it's tangled in his hair, and he gasps as it sends heat blazing through his veins and down his spine.

"Don't be greedy, brat. You'll take what I give you, and you'll say thank you."

"Yes ma'am," he moans.

"Good answer. Now on your knees."

He drops like a stone, staring up at her like the goddess she is.

"Crawl," she demands, tugging him by the hair.

He's glad for the soft carpet as she leads him across the room on his hands and knees, stopping at the edge of the bed. He doesn't know when his towel came off, but he can feel the cool air on his dick, the tip wet and leaking.

"Denki, right?" She asks.

He nods, watching with wide, hungry eyes as she sits down in front of him, legs open just enough for him to catch sight of soft pubes and the swollen lips of her pussy.

"You ever eat a girl out, Denki?"

He licks his lips longingly, his eyes locked on his prize. "Yes, ma'am."

He can smell her there, some kind of musky, feminine aroma of arousal that makes his dick jerk where it's hanging between his legs and his mouth to fill with saliva.

"Good, then you at least have an idea of where to start."

He glances up at her, slightly cocky.

"I've been told that I'm pretty good, ma'am."

She cocks an eyebrow at him, a slow, savage grin crossing her face.

"We'll see about that. Now, deep breath."

He inhales, and then seconds, later, he has a mouthful of pussy.

He immediately moans, his eyes rolling into the back of his head as he licks a slow, eager stripe over her clit, making sure to swirl around the swollen nub as he goes back down, and cheers smugly in his mind when Mitsuki gasps softly.

"Well, we'll, at least you know what a clitoris is," she says aloud, her voice breathless as she pushes against his face.

He whimpers, clenching his hands tightly into the carpet, and does it again, eager for more of that smokey taste on his tongue.

He's loud with it too, slurping and groaning loudly into her flesh, feeling proud when her thighs begin to tremble where they rest on either side of his head.

"F-fuck, you're doing a way better job than I thought you would," she moaned, her head falling back against the bed.

He gives her a little extra attention to her clit for that, swirling his tongue around in tight circles that cause her to gasp and grip his hair a little tighter.

"Shit!"

He gets bolder as she slowly deteriorates underneath his tongue, and pushes two fingers inside of her.

It's low-key probably the hottest thing that's ever happened to him.

She grunts when he does it and clenches tight around his fingers, her back arching off the bed as she grinds against his face.

"Fuck, that's nice, baby. Curl your fingers-ah! Y-yeah, like that..."

He moans against her flesh as he curls upwards, pressing against the soft insides searchingly until her soft cry of pleasure fills the room.

After that it's only a matter of time, effort, and tongue flexibility before she's cumming with a strangled whine.

She's still breathing heavy when he pulls away, licking the taste of her from his fingers with a soft moan.

"Well, goddamn, brat, you aren't half bad," she admits.

"Thank you. It's definitely the one thing I'm most proud of," he responds, chest puffed up with pride.

She chuckles, sitting up with a small grunt. "Well, that was a pretty good appetizer. Now, are you ready for the main course?"

"Hell yes, please. But uh, do you have any condoms?"

"Condoms? For what?"

"W-well, I can't just like...have my jizz all in you."

She stares at him for a good few seconds before bursting out laughing.

He's immediately offended. "What?! Look, I am always up for sex, I am /totally/ not ready for the baby that might come with it."

She wheezes, waving a hand at him. "Stop! Stop! I'm gonna pee!"

He huffs, crossing his arms and pouting, waiting for her loud laughter to fade into mild chuckles.

"Oh, you're pretty funny, aren't you?"

"It's not funny to practice safe sex," he says sulkily.

"True. But who said you were gonna fuck me?"

He blanks.

He yelps as she grabs his chin and yanks him up against her body, his hands flying out to catch himself on either side of her.

"No, no, baby boy," she murmurs into their shared breathing space, reaching out to tuck a strand of hair behind his ear, sending shivers down his spine.

"See, only real men get a chance to fuck this pretty pussy," and here she cants her hips upwards, letting the wet slide of her slick/saliva coated lips glide across his still very hard dick, causing him to whimper quietly as he stares into red eyes.

"And you're just a baby."

"'M not," he whispers, but it sounds whiny and pathetic to even his own ears, so he's not surprised when she gives him a condescending smile that makes him melt against her.

"You are. You're a small, cute little baby boy, and baby boy's don't get to fuck their Mommies."

He gasps when she says it, something hot and potent stabbing him straight in the dick, sending a hot dribble of precum leaking down the side.

"Babies get fucked by their Mommies. Now the question is."

He yelps when she rolls them, staring wide eyed at her sitting on his hips.

"Are you gonna be a good boy for me, Denki?"

He shivers, digging his hands into the sheets so that he doesn't just reach down and jerk himself off until he cums hot and sticky all over her back.

"Yes, Mommy..."

"On your knees," she demands as she lifts off of him, heading to the dresser across the room as he scrambles to obey, letting his chest hit the bed and spreading his legs wide.

He can see her rummaging around, and it makes his heart pound, not knowing what she's gonna pull out.

But it also makes his dick hard, so he can't really be too nervous.

And then, holy fuck, suddenly he can see /exactly/ what she has.

"That's not gonna fit," he whispers, eyes wide.

The blond woman chuckles, slapping her palm with the fucking huge dildo she had just pulled out.

"That's what they all say. But trust me, baby, I know exactly what I'm doing."

He watches her get rigged up, strapping on some kind of device with a little mini dildo on the crotch area that she inserts inside of her with a small hum of pleasure before locking it in place.

And then warm hands are dragging down his back and squeezing his ass firmly.

"M-mommy," he whines, burying his face into the pillows as she starts to knead his ass with two firm hands that are...slowly starting to get sticky?

"A-ah! What's-?"

"Glycerin," she hums, dragging a suddenly wet thumb gently around his hole, which he can feel clench tightly. "'S my Quirk. It's good for the skin, and makes a great lube."

He whines when she pushes against his hole ever so slightly, wiggling her thumb back and forth.

And then there are more fingers, and then a hand, spreading him open so that two of her dainty fingers can trace around the small opening, getting wetter and wetter from her Quirk until one of the finally slips right inside with a small squelch.

"Ah!"

"Easy," she murmurs, her voice soft and sweet as she pushes a little farther inside, the weirdness of it causing his to gnaw on the pillow beneath his head. "It's just a little sting. It's not that bad. You can take it, right? Aren't you a good boy?"

And fuck if that doesn't make him relax against the mattress, his mouth falling open to pant softly as another finger slips inside, stretching him open just a bit more.

"Mommyyyy," he whines weakly, his hips twitching back.

"Shhhh, you're doing so great baby, you're gonna look so good on Mommy's dick, gonna take it so good, aren't you?"

He whines louder, his legs spreading of their own free will as he arches his back. "Please Mommy, I'll be good, I promise," he babbles, drool sliding down his chin.

She croons at him, soft and pleased, and eventually another finger eases in next to the first two.

It burns, but he's not unused to it, having played with himself plenty of times and by Mina. He's not even unused to being fucked. But Mina is cautious and unsure.

Mitsuki is firm and confident, and she finds his prostate almost immediately, causing him to writhe against the sheets in pleasure.

"Mommy!"

"Such a good boy," she growls, and he whines when she fucks him a little harder, dragging her fingertips across the soft spot.

And then they're gone and he's /so/ disappointed for all of three seconds before the soft, silicone head of her strap is pressing against him.

"Ready?" She asks, and she sounds a little breathless herself.

"Please!"

It's a stretch.

It's definitely a stretch.

He gasps, tensing as pain rips through his body. "M-mommy-!"

"Shhh..."

Soft, firm hands massage at his back and hips, finding all of the tight spots and working them over until he's a relaxed puddle against the bed.

"Easy baby, it's okay," she murmurs, and he can feel her secreting more glycerin, rubbing it around his stretched hole and coating the dildo with it, making her next thrust that much easier.

He whines, gripping the bed with shaking hands as his body opens for her.

Until her hips are pressed against his own.

"That's my good boy," she whispers, running a still slightly sticky hand through his hair as he whimpers quietly, blinking back his tears.

"Full," he moans back, his thighs quivering. "So full, Mommy..."

"Does it hurt any more?"

He shifts, and besides the low sting of being stuffed, it doesn't hurt that bad.

"'S good. Want more."

Her hand becomes tight, commanding, he's overcome with the sudden feeling of being dwarfed by someone twice his size.

"Now, now. Is that any way to ask Mommy to fuck you?"

He shakes his head, quickly, gasping when she pulls her hips back, all the way to the tip.

"Say it."

"Please, fuck me Momm-AH!"

He doesn't get to finish his sentence, her powerful hips snapping against his own.

"Mommy!"

He gasps, clinging to soft sheets as she begins to fuck him, slow, deep thrusts that have his thighs quivering with the force of it.

"What a good boy, taking me so well," she groans, watching herself slide in and out of him lewdly.

It's just as good for her as it is for him, each snap of her hips causing the curved mini dildo inside of her to jab against her sweet spot. Making her own slick drip down her legs as arousal curls in her gut.

Denki is moaning, whining, desperate.

Obviously experienced, but not in the way she is. He's only a boy after all.

A soft, pretty boy who makes the cutest noises when she angles her hips /just/ right.

"M-mommy! Mitsuki!" He gasps, his head flying back as he drips precum all over the sheets.

"That's a pretty pet," she coos at him, twisting a dominating fist in those longish blond locks and tugging roughly, sweat sliding down his face and between her jiggling breasts. "Louder. I wanna hear you scream."

Fucking /no/ problem.

He starts wailing, letting all the noises he had unconsciously been holding back fall from his lips, becoming louder and breathier with each thrust.

In fact, he's /so/ loud that neither of them hear the door creak open.

"Bakugou Mitsuki."

A voice, male, whips through the air.

It makes both of them freeze like deer in headlights as they look up.

A man is standing there, both arms crossed. He looks to be around his early forties, with brown hair and glasses that he's using to stare through at them on the bed, fighting what appears to be a smile.

"Mitsuki," he says again, softly, walking over to them on socked feet. "What are you doing?"

Any reply or action Denki might have come up with flies out of the window when the woman behind him starts to roll her hips, causing the head of her strap to grind against his prostate

It forces a gurgling cry from his throat, his body seizing with pleasure.

"Masaru! I was wondering when you would be home," she coos, and behind him he can hear the wet sound of a kiss.

He wants to be freaked out, but holy FUCK that strap has some kind of sedative in it.

"And who is this delightful young man that you're taking apart on our bed?"

"This is Kaminari Denki," she says, thrusting hard on the last syllable so that another cry is forced out of his mouth. "He's a school friend of Katsuki's."

Gentle fingers card through his hair, causing him to moan weakly as his body is propped up so that the man in front of him can see his blissed out, flushed face.

"Isn't he adorable, Masaru?" Mitsuki purrs, her soft hands tracing across his shivering body.

Masaru's gaze is scorching him from the inside out, hunger in his eyes that matches Mitsuki's perfectly.

And if he thought one person watching him fall apart was arousing, /two/ people is making his dizzy with lust, his dick bobbing with need as he keens.

"He does look very...pretty," Masaru murmurs, and Denki whines when large, slightly rough fingers trace his cock from the base all the way to the tip.

"A-ah!"

"And he sounds so pretty, doesn't he?" She coos, nibbling at one of his earlobe as her hips thrust lazily.

"Oh yes, very pretty," the man murmurs and fuck, Denki has never been in this kind of situation before and he was wholly unprepared for how turned on he would be once in it.

"He sounds even better getting fucked," Mitsuki purred, and Denki could feel her wicked grin.

"Does he?" Masaru hummed, fingers tracing from sweat dampened pubes all the way up to flushed, erect nipples. "And what about if I touch him here?"

A rough, twisting pinch has his head flying back against Mitsuki's shoulder as a cry flies from his mouth.

"/Daddy/!"

"Fuck," Masaru swears harshly, reaching forward to cup his little tits in soft, large hands. "You're already so well trained."

"He learned from the best," Mitsuki purrs, her own smaller hands wrapping around both of his hips to tug him back.

Denki moans breathlessly, looking up at Masaru with glazed eyes as she slowly begins to rock her hips once more, weak hands gripping the man's dress shirt as tightly as he can.

"D-Daddy, fuck, 'sgood," he whimpers, panting as lithe fingers squeeze his nipples even tighter.

"Fuck, you're a real pretty one, aren't you?" He responds, eager eyes traveling across his face before coming to a stop on his open, panting mouth. "Bet I could make you even prettier."

And Denki whines, high and pretty, his small tongue swiping across his lips.

"Is that what you want, baby boy? Want me to fuck your pretty mouth while my wife fucks your pretty ass?"

That wakes him up a little bit.

"W-wife?!"

"Well, of course I'm his wife," Mitsuki chuckles into his ear, biting on the lobe in a way that makes him drip onto the sheets.

"Who else would I be? Katsuki's /sister/?"

And holy fucking shit, if that was his wife then that means he's Bakugou's dad and if HE'S Bakugou's DAD and SHE'S Bakugou's dad's WIFE then that means-!!!

"Oh my fucking god, you're Bakugou's mom," he wheezes.

Her answer is sharp, amused laughter and then he's being roughly bent over on the bed as she begins to fuck him with rough, even thrusts that immediately turn his brain into nothing.

"Ah! Ah! AH! M-mommy!"

"Mmmmmm, gooood boy," she groans, watching him become a fucked out mess.

To be honest, he really should be having some kind of internal crisis, and he probably will do that later, but the feeling of her stabbing roughly at his prostate is making all of his common sense fly out of the window.

"Mistuki," Masaru murmurs disapprovingly.

"Did you tell this boy that you were Katsuki's sister?"

"Noooooooo," she drawls with a slow, swirling roll of her hips that has Denki convulsing against the sheets. "He /assumed/ I was Katsuki's sister, and I didn't correct him."

Masaru sighs, and it's tired, but ever so fond.

"Of course you didn't."

"And besides, how could I not jump him?" She purrs, dragging her nails down his back as he shudders, moaning loudly. "You should have seen him, Masaru, he was almost drooling for it. His dick was so hard in his little undies."

Denki can feel thick fingers tangling into his hair, and then he's being gently lifted until he's once again pressed against Masaru's chest.

"Is that true?" He asks him softly, his smile soft and friendly even though his eyes were dark and dangerous.

"Were you drooling over my wife, pretty boy?"

He chokes on his spit when Mistuki thrusts as far as she can in one go, his hands clenching tight into green shirt fabric.

"A-ah!"

"Tell him," she purrs, and then he's being sandwiched between two pairs of soft but firm tits.

"Tell him about how you wouldn't stop watching my breasts in that little tank top," she purrs in a flushed ear while her husband bites softly at the other one, making his body almost vibrate out of existence. "How you couldn't stop looking at my legs in my shorts."

Masaru laughs softly, reaching down to grip one of his ass cheeks in each hand and spread him open even more, which means Mistuki is able to fuck him deeper, which probably means he's gonna die. "Ah, the little yoga shorts, right? They get 'em every time."

Just how often do they do this??

"Masaruuuu," Mitsuki purrs, and then there's the wet sound of another kiss, but this one sounds /lewd/ and /dirty/, and it makes Denki's cock jump where it's pressed up against Masaru's leg.
