Chapter Text

Episode 1: Electric Cravings, Pink Sparks, and Shattered Glass

 

The front door of their brand-new apartment slammed shut with a solid thud that rattled the half-unpacked cardboard boxes still scattered across the living room floor.

Denki Kaminari didn’t bother flipping on the lights as the midafternoon still showered the windows half illuminating the mess their new home was. With a vicious grin he had Kyoka, not Jirou anymore but Kyoka Kaminari, pinned against the nearest wall before she could draw a full breath he had his mouth crashing hers into a kiss that tasted like pure, electric need; teeth nipping, tongue sliding deep and unapologetic as the faint crackle of leftover static dancing across his fingertips where they dug into her hips out of the excitement of this new chapter in their lives.

Twenty-one years old, freshly married, and still stupidly, helplessly addicted to the woman who’d been his high-school sweetheart since second year. Kyoka gasped into his mouth, her earphone jacks shooting out on instinct to wrap around his neck and yank him closer, something she did all the time to show how much she craved for his attention. She was just as needy for his love as he was for hers, ever since the wedding their hunger had turned feral, fucking almost every day, sometimes twice or thrice if one of Denki’s sparks hit the right spot while groping each other.

She was pregnant. Two months in as they found out right the previous week from the wedding and, far from making him be terrified our electric blond became shockingly excited about it as he seemed excited to become a father . . . And also, for some reason, it made him extremely horny for his beloved Kyoka.

“Denki—!” She managed to whisper through a half-laugh-half-moan as he shoved her shirt up and throw it over one rough motion, perky breasts spilled free, nipples already hard and begging for his love and he didn’t hesitate to latch onto one immediately, sucking hard enough to make her arch in delight, tongue flicking the sensitive bud while his hand attacked the other, pinching and rolling until she was grinding against the thick bulge straining his jeans with the same hunger he use on her perky tits.

“Been thinking about this all-damn day~” He growled against her damp skin between husky sucks, voice low and rough with need. “Finally got our own place~ No more thin walls, no more worrying about neighbors hearing how loud you scream when I fuck you raw~” His free hand yanked her pants and panties down in one tug down to her knees and she cooperated instantly, moving her legs to make them drop and kicked them away impatiently and as soon as her beautiful Venus was free Denki dropped to his knees right there in the entryway like a man starving, hooked one of her legs over his shoulder, and buried his face between her thighs without warning as Kyoka’s rested her head back against the wall.

“Shit—!” Her voice cracked as his tongue dragged through her soaked folds, licking broad and filthy, sucking her swollen clit with obscene wet sounds that seemed to loud not to be on purpose. Two thick fingers pushed inside her tight heat, curling hard against that spongy spot that always made her thighs shake and he knew damn well after half a decade of being together. She was dripping already; her puffy pussy was slick from how badly she’d wanted this the whole drive over. Earphone jacks trembled, one wrapping tight in his blond head and yanking him closer as she rode his face shamelessly, waving her hips sensually to let her husband taste all she had to offer.

“Right there~ Fuck, Denki, don’t stop~ You damn pussy eater~!” An orgasm hit fast and sharp. She came with a broken cry, thighs clamping around his head as if wanted to squeeze the last braincells in that dumb-dumb head of his, juices flooding his tongue and dripping down his chin was the best reward he could ask for but didn’t let her come down easily because the second her spasms eased, he stood in a blink of an eye, spun her around and bent her over the arm of their oversized new sectional couch with clear and well-practiced intentions.

His cock was already out: Thick, veiny, flushed dark and leaking in that swollen tip her pussy knew damn well, well her pussy and all of her body after all the times they got down and dirty. It took him a second to find the right angle to thrust himself in, bottoming out with a wet slap of skin on skin as Kyoka’s eyes went crossed and a silent moan died in her mouth before they groaned together, the sound of their bodies melting in one was raw, filthy, perfect. Kyoka’s walls fluttered around him, still pulsing from her first climax, squeezing him like a vice and Denki gripped her hips hard enough to bruise and started pounding with deep, vicious strokes that made the couch creak and her tits bounce beneath her.

“That’s it, baby.” He snarled, one hand sliding up her back to fist that violet hair and yank that pretty head back ripping another moan from her that was as melodious as her singing voice, a siren song for her dear husband and she knew it so well it became a weapon to entice him when needed. “You’re mine, I’m yours and I’m going to fuck you stupid on every surface of this place that is our new home.”

Kyoka moaned shamelessly, pushing back to meet him, voice full with desire as her body experienced tremors of excitement every time he calls her his and every time he refers as hers.

 “Harder! Fuck me harder, Denki! God damn it, you know how I like it!” He gave her exactly what she begged/demanded for: Long, powerful thrusts that slammed balls-deep every time, hips snapping against her ass with loud, wet smacks from the sweat of both combined, earphone jacks went wild; one wrapping his wrist holding her hair as the other teased his heavy balls with vibrations that hit the right spot to make him growl like the horny dog he became when alone with her, he reached around, rubbing tight circles on her clit with his free hand while he keeps railing her mercilessly.

Kyoka’s second orgasm crashed over her even harder; screaming his name as her cunt clamped down, gushing around his cock. The squeeze was too much for Denki who buried himself to the hilt and came with a guttural moan, thick ropes of cum flooding her womb, pulse after pulse, until it leaked out around his shaft.

They stayed locked together, panting at the same rhythm as his cock was still twitching inside her. But he wasn’t done, hell no, not even close done with his beautiful wife and just pulled out with a wet squelch, flipped her onto her back on the spacious couch, spread her legs wide as his cum was already dripping from her bullied hole. The sight made him twitch back to full hardness in seconds.

“Look at that messy pussy.” He grinned, voice dark with fresh lust and electric desire. “Already full of my load and still begging for more. Aren’t you a very naughty wife?” Asked with pure need, as every time he call her that, wife, something triggers in both of them. Kyoka stared up at him with hazy, lust-drunk eyes, biting her lip in the most sensual way as she reached down and spread her folds with two fingers, showing him the creamy white leaking out, a simple call out for action.

“Then give me more, husband.” She purred, voice wrecked after the moaning concerto but needy as she knew that tone was enough to make Denki forget about everything and focus on her and only on her. “Fuck your pregnant wife until she can’t walk.” Denki’s eyes flashed electric golden for a second; she just said all the trigger words to make him go feral, so he hooked her legs over his shoulders, lined up, and slammed back inside her cum-slick heat in one savage thrust.

The real fucking had only just begun.

Hours later the apartment had gone quiet except for the soft rhythm of their breathing. Denki lay tangled with Kyoka on their bed, one hand resting protectively over the gentle curve of her still-flat belly, thumb tracing lazy circles as caressing their child who was just the size of a lemon at that time. The moving boxes around them were forgotten, clearly a task for another day as the only thing that mattered was the warmth of her skin to him, the scent of sex and sweat clinging to both and the quiet certainty that this was their home now.

Morning light filtered through the curtains, painting warm golden stripes across the master bedroom floor as Denki woke first with a lazy, satisfied grin already plastered on his face, body still hummed from last night’s marathon but it was something he found more gratifying than a nuisance.

He rolled over, pulled Kyoka closer, and pressed a kiss to the nape of her neck as she stirred, pushing her ass back against his morning wood with a soft, content hum without opening her eyes.

“Round four already, Spark plug? I just woke up . . . And you’re hard as a rock~” She teased, voice still raspy from screaming his name and many other naughty things the previous night. Denki chuckled playfully and nipped her shoulder.

“Can’t help it.” Said casually before kissing her forehead. “Knowing you’re carrying our kid makes me want to fuck you even harder and if you keep triggering me with that naughty voice of yours I’ll end up fucking you in every centimeter of this house in less than a weekend.”

The doorbell rang before he could slide back inside her, Kyoka groaned as she was ready for more electric love and instead got her metaphorical balls blued.

“If it’s the delivery guys tell them to leave the boxes in the entrance, all the important stuff is already in the house.” Pouted a bit, ironically the mature one of the married couple was the one throwing a tantrum now.

Denki threw on loose sweatpants as his cock still half-hard was tenting the fabric and padded to the door. When he opened it, a burst of bright pink was there waiting with the biggest of smiled making him smile back instantly.

“Mina!” Shouted, lighting up his spirits like a live wire as the dumbest smile grew on his lips at the presence of his best friend Mina Ashido who launched herself at him, wrapping arms around his neck in a crushing hug.

“Denki! I missed you so much, bestie!” Said covering his face, except his lips of course, with kisses.

He laughed and spun his friend once before setting her down.

“Bitch, you saw me a week ago at the agency briefing before going to my honeymoon.” Rolled his eyes playfully, he did miss her in that short period too but won’t say it to avoid feeding her ego.

“Seven days is forever without my dumb-dumb best friend! Or you didn’t miss me at all?” She pouted dramatically, eyes sparkling with mischief like always but it was replaced with an excitement Denki had never seen on her before. “We’ll talk about how much of a terrible friend you are later but first; I have news! Big news! Where’s Kyoka? Get her out here right now!” Demanded stomping her fancy heel in the entrance floor to continue with her pout.

Kyoka emerged from the bedroom in one of Denki’s oversized shirts, violet hair messy, a few fresh love bites visible on her neck. Mina’s eyes widened with delight, she lost count of the number of times she had found her rocker friend that way with Denki around in high school and, honestly? She grew accustomed by now.

“Kyoka! You look freshly fucked and glowing already!” Teased all casual, waving her hips playfully.

Kyoka rolled her eyes but smiled. “Shut up, Mina.”

They ended up in the living room surrounded by half-unpacked boxes. Denki made coffee while Mina bounced on the very same couch where he had railed his wife senseless the night before. The pinks for brains element try to make a grand, elaborated thing to explain the situation but instead simply lift her shirt a bit and show her plain stomach . . .

“Two months preggers” She squealed, tears of pure joy already welling in her eyes as the biggest, dumbest smile was plastered all over her face. “Eijiro and I find out a week ago before he went on that long mission up north. We said we’ll tell you all together once he returns but I wanted to tell you guys first!” The couple seemed shocked for a second before Denki jump and yell so loud it probably echoed through the whole building as he scooped Mina up, spinning her in circles while she shrieked with laughter.

“My best friend is having a baby! Holy shit, we’re both gonna be parents! I’m going to be a dad and an uncle! Our kids are gonna grow up together and be the bestest of friends like you and I!” All words coming from his mouth made him sound more excited by the second showing Mina just how happy he was for her.

Kyoka’s usually cool demeanor changed for the one of her brightest and most sincere smiles ever. She pulled Mina into a tight hug the moment Denki set her down, voice soft with genuine warmth.

“Congratulations, Mina. I’m really, really happy for you.” The happiness in her friend reminded her of her own and                 the sonic hero knew there was nothing better in this world that knowing you’ll be having a child.

The next few hours were pure sunshine and rainbows. They dreamed out loud about nursery ideas, ridiculous parenting fails they’ll probably commit and how their kids would team up to conquer the U.A. one day probably making poor Aizawa and Deku retire from teaching.

 Denki kept pulling Kyoka onto his lap, kissing her temple and rubbing her belly with open adoration while Mina gushed about Kirishima crying ‘manly tears’ when he found out.

“I’m the happiest I’ve ever been.” Mina said at one point, hugging both of them tight. “My two favorite people are becoming parents, my boyfriend and I are becoming parents.” A faint sob escaped her mouth, not of sadness but happiness so overwhelming it was too much for her pregnant person. “After all the villain fights and near-death crap we had to endure while studying to become heroes . . . We’re actually winning at life.”

Denki felt his chest swell with pure, unfiltered joy as everything felt perfect because everything was perfect.

Later that evening Mina left them to attend a doctor appointment, regular checking she said and now Denki and Kyoka were alone as they were tangled on the couch, lazily making out and enjoying each other company, whispering occasionally to say something but refusing to move without a good reason when Denki’s phone started ringing, making both groan as he whispered “This better be important” to interrupt him in one of his last days of post-marriage vacations but his anger died when he recognize the caller and smiled instead.

“It’s Mina again. Probably forgot something, I swear that dummy–” He answered with a cheerful, “Yo, Pinkie Pie! Missing us already?” But all that happiness died in seconds as the voice on the other end was nothing like the bright, bubbly Mina from earlier nor any version of Mina he had ever knew.

It was . . . Small.
Broken.

Shaking so badly it sounded like every word was being dragged through glass.

“Denki . . .?” His smile dropped instantly and Kyoka perked up as well knowing her husband never erase that silly smile of his face unless something truly serious happens.

“Mina? What’s wrong?” A long, painful silence and then a choked sob that tore straight through the line unto his heart.

“Denki . . . I . . . I went to the doctor after I left your place. Just to be safe, you know? It was a routine check-up” As she spoke his eyes went wider, the time got slower and even when he wanted to punch himself and wake up from, in the making, nightmare he knew it was damn real. “No heartbeat.” Denki felt the floor drop out from under him, creating a void that swallowed him whole as Kyoka sat up sharply, concern flooding her face as she saw his expression change from serious to utterly devastated.

Mina’s voice cracked completely, dissolving into raw, guttural weeping that sounded like it was being ripped from her soul alongside all the joy and happiness.

“It’s gone, Denki! My baby is just . . . Gone! I was so happy today. I told you first because you’re like a brother to me and I thought everything was finally perfect, but it’s not! It’s empty now and I don’t know what I did wrong! Eijiro isn’t here, I can’t contact him . . . I’m all alone in this stupid apartment and my baby is just . . . Gone.” She was crying so hard she could barely breathe, the kind of deep, hopeless sobs that made your chest physically ache just hearing them and in Denki’s case, someone who knew Mina so well it was simply mind-crushing “I was gonna be a mom . . . And now I’m nothing. It hurts so much, Denki. It hurts worse than anything in my life . . .”

The call ended with one last broken sob that echoed in Denki’s ears long after the line went dead.

He stared at the phone, the joyful laughter from just hours ago now feeling like a cruel joke as Kyoka reached for him, but he could barely feel her gentle touch that usually comfort him in the darkest of moments as all he could see was Mina’s radiant smile from earlier and now the image of her completely destroyed, sitting alone in the dark with nothing but silence and pain where her baby should have been.

It took him ten seconds of being completely stunned before his brain reconnected with reality and roll out, barely remembered the drive, hands gripped the steering wheel so tight his knuckles turned white, faint electricity crackling across his fingertips every time Mina’s broken sob replayed in his head as a sign of impotence and anger with himself for taking so long to be there, groaning at every minor inconvenience in the way, every red light, every car in his way releasing the anger he felt for not being right now with the friend who needed him so bad.

When he knocked on the door, it opened almost instantly.

Mina stood there, looking nothing like the glowing woman who had hugged him earlier that day: Her bright pink skin was dull, eyes swollen and red through the black sclera, golden irises empty. Tear tracks stained her cheeks as she was still wearing the same cropped top, one hand unconsciously resting over her flat stomach as if trying to feel something, anything, her baby.

The moment she saw him, her face crumpled completely in a way that crushed his soul like nothing before.

Denki . . .” Called his name in the softest whisper ever, the softest call for help on his life but also the strongest.

He didn’t say a word and just stepped forward, pulled her into his arms, crushing her against his chest while Mina buried her face in his shirt and utterly broke down with ugly, guttural sobs tore out of her as her whole body shook violently with a mix of impotence and full anger on herself, on the world, on the cruel destiny. Her fists clutched the back of his hoodie like she was drowning and he was the only thing keeping her afloat.

“Denki, I lost itI lost my baby!” She wailed as words muffled against his chest. “It was there this morning and now it’s just gone! Why? Why did this happen to me? I was so ready! I was eager to be a mother! To hold my baby, to name my baby, to love . . .” Words died out between a mix of sobs and whimpers.

Denki held her tighter, one hand gently stroking her pink hair, the other rubbing slow circles on her back. His own throat burned, but he forced it down because right now, his best friend needed him steady, to be a rock she could anchor in a moment her life was crushed to never be the same.

“I’ve got you” He whispered fiercely; voice full of pain but also with determination to make her feel she wasn’t alone in a moment that no words, no actions, not a thing could fix what was happening. “I’m right here and I’m not going anywhere, Mina. Not until you tell me to.”

They stayed like that in the doorway for a long time, with Mina sobbing until she was gasping for air, Denki holding her through every wave of pain and hold her tighter when she debacle into sobs that were more like painful howling and when her legs finally gave out, he scooped her up and carried her inside, kicking the door shut behind him.

He laid her down on the couch and sat beside her, never breaking the physical contact she clearly needed as Mina curled into his side like a child, head on his lap as fresh tears soaked through his pants.

Kyoka had stayed behind the moment Denki told her what happened, not out of disinterest for Mina but because only Denki had the strength, or at least she hoped he had, to face this situation as she, an expectant mother, would probably crumble in the situation. She understood without saying a single word in protest and simply kissed him hard knowing what he will face and said

“Go. She needs you more right now.” Then called her mother for support as Denki was with Mina.

Mika Jirou arrived within minutes, kind-hearted and steady as always. “You focus on Mina, Denki” His mother-in-law had told him over a message. “I’ll stay with Kyoka, you take all the time you need.”

That first night, Denki barely slept.

He stayed on the couch with Mina, feeding her small bites of soup when she finally agreed to eat something but she threw most of it up afterward, crying harder because even her body felt like it was betraying her increasing the ragging guilt crushing her soul and guts.

“I was supposed to be a mom . . .” She whispered in the dark, voice hoarse and defeated. “Eijiro is coming home to nothing: I failed him, I failed our baby, I fail our family

“You didn’t fail anyone.” Denki said softly, fingers combing through her hair. “This isn’t your fault, Mina. Sometimes horrible things happen but you’re not alone in this, not for one second.”

Over the next several days, Denki became her shadow guardian.

He slept on the couch every night, waking whenever she had nightmares or started crying again at 3 a.m.

He cooked simple meals: Rice, eggs, anything she could keep down and that he could coaxed her to eat, helped her shower when she didn’t have the energy to stand, keeping his touch respectful and gentle, only there to support her when her legs shook and her spirit fail to hold her up.

They talked for hours.

Some days she raged while screaming at the ceiling, acid tears burning small holes in the floor until she exhausted herself.
Other days she was completely silent, staring at the wall with dead eyes while Denki sat beside her, shoulder to shoulder, just existing with her in the pain and offering a warm anchor to reality.

He told her stupid stories from their U.A. days to fill the silence, to help her remember better times, how they both nearly failed every test, how they used to sneak snacks during supplementary lessons, how she once covered for him when he accidentally short-circuited the dorm’s power during a prank.

“You’ve always been the strongest out of all of us, Pinkie Pie” He said one quiet afternoon, sitting on the floor while she lay on the couch. “Not because you never fall, but because you always get back up, even when it hurts like hell, I know you’re gonna get through this too and I’ll be right here until you do.” His words weren’t just the classic, stupid shit one says to a sad person hoping to improve their humor during a sad day as each word was given to her with complete and total honesty, showing how much he care for her, for her future and her general wellbeing.

Mina turned her head slowly, eyes red-rimmed and exhausted but for the first time in days, the tiniest spark of gratitude flickered in her gaze.

“You’re the best friend anyone could ever ask for, Denki . . . Thank you.”

He smiled sadly and reached up to wipe a stray tear from her cheek with his thumb.

“Best friends don’t thank each other for this shit. We just show up.”

By the end of the first week, Mina was still devastated, hollowed out and fragile, but she was no longer completely alone in the dark as Denki’s constant presence, his dumb jokes, his quiet strength and his unwavering loyalty had become the only thread keeping her from falling apart entirely and only God knows where she’ll be right now without him. . . Or if she’ll be there at all.

Still, every night when the lights went out, she would curl up smaller on the couch, hand pressed to her empty stomach, and whisper the same broken question into the darkness:

“Why did my baby have to die . . .?”

And Denki would stay right there on the floor beside her, holding her hand until she cried herself to sleep, his own heart aching with a pain he didn’t know how to fix, how to . . . Heal.

The apartment that had once echoed with bright laughter now held only the quiet sounds of shared grief and the steady, electric promise that she would never have to face it alone no matter how painful it is.
