Bakugou couldn’t deny what he was doing was wrong, he was an intelligent man. But there was just something so alluring about you that made it so difficult for him to stop. The nights he lay in bed now plagued with thoughts of you as his thick cock stirred between his strong thighs. Often causing him to get up in the small hours of the morning just to relieve himself, sometimes passing by your room in the hopes you’d gone to sleep in a compromising position again.
He loved hearing you complain about the house being too hot, making you go to sleep in the skimpiest pyjama sets known to man, so much skin on display there was really no point in even wearing anything. Bakugou stared at you with glee when he realised his plan had worked, leaving the thermostat at an uncomfortable temperature and telling you that he promised he’d fix it, just for you.
Your body sprawled out invitingly for him on the bed, kicking the covers off yourself during the night as you lay on your side. One of your thick thighs over the other as your shorts pulled up between your round cheeks, wishing he could run the heavy length of his cock between them. His vermilion eyes moving towards the swell of your breast, barely concealed beneath the matching pyjama shirt. Groaning as he palmed himself through his shorts, the underside of your tits more defined in this position. Your darkened areolas peeking out beneath the top invitingly, making him want to reach out and tug the fabric up.
Fuck, you were perfect. His shorts already pulled down just enough to free his aching cock, wrapping a large palm around himself as he gave a teasing pump. Circling his wrist as he reached his leaking tip to catch some of his pre and glide it along his length for lubrication. Jerking himself off at the sight of you, your pouty lips parted in quiet slumber as he imagined the plush head of his cock slipping between them. Making tears stream down those pretty cheeks as he fucked your face with his cock. Feeling his tip hit the back of your throat with each forward motion as he began to speed up his pace around his cock. It shouldn’t be allowed for one person to be this fucking hot, taking a chance to move his deft fingers towards your shirt as he tugged it. Pulling it up around your breasts as he watched them spill out, the sight causing his hips to stutter as he cursed under his breath. Your pretty nipples looked so soft and little. Wanting to reach out to pinch and tug at them to watch them harden against his touch. A choked moan leaving his lips as he cupped the palm of his hand around his tip, moving his fist frantically as he came with a grunt into his palm. Slipping from your room with his pants still around his thighs as he made his way towards the bathroom to clean himself up, climbing back into bed with his wife.
Satisfied for now.
You had to know what you were doing, there was only so long you could put on this innocent act for him. Acting like you were coy and naive but Bakugou knew you were anything but. Starting to wear more revealing clothes around the house, walking past him towards your bedroom clad in only a towel after your showers, leaving your dirty panties on the side for him when he stepped inside the bathroom and having it smell like you.
He was playing a dangerous game, and he knew it. His wife was suspicious that his sex drive had mysteriously decreased but he played it down to arduous work as a Pro-Hero. It was difficult trying to maintain the number two spot and there were mornings he would come home tired and aching. Dropping himself onto the couch with a grunt as his wife tried to get his dirty self off the material and into a shower as she readied herself to leave for work.
He wasn’t even trying to hide it now, whenever he’d barge into your room when you were home and his wife was at work. Openly ogling you as he sat with his thighs spread invitingly, still dressed in his hero costume as you made your way past him to the kitchen. The round curve of your ass was blatantly visible underneath the oversized shirt you were wearing as his cock throbbed impatiently, wishing he could come up behind you and bend you over the counters.
“Gonna make a coffee for your old man?” Bakugou shouted to you from his position on the couch, smirking when you turned to look at him with those pouty lips of yours.
He didn’t get a response but a large mug of coffee was placed in front of his parted thighs on the coffee table obediently, giving him a chance to openly stare at your exposed skin.
Bakugou was no fool, he knew it was wrong. He was well over twice your age and had many more years of experience. The boys that had probably touched you before definitely didn’t know what they were doing, tumbling hands squeezing and tugging your body uncomfortably as they humped themselves against you. The thought alone had Bakugou seething, those fuckers didn’t deserve to touch what was his. Beginning to wonder if you’d ever really been with a man before or if you got yourself off. Thoughts instantly moving to how your cute little fingers would look stuffed inside your tight cunt. Whether you were even able to curl them properly to catch against the spots you needed to touch to get yourself off. Maybe you just toyed with your clit, spinning quick circles against it as your hole was left empty and available. A space that he would be more than willing to fill.
Leaning forward with a groan of his aching limbs Bakugou raised the mug of coffee to his lips. Chugging the warm liquid as it soothed his throat, the fact that you’d made it for him made it taste that much better. You were always such a good girl for him. Giving himself a few more minutes before he rose to his feet, intent on taking a shower and getting rid of the day's dirt and grime from his body.
Starting the shower as he began to disrobe. Letting the heavy utility belts clank to the floor as he pulled it pants down his muscular thighs, his underwear pooling around his ankles as his semi-hard cock hung between his legs. A messy mixture of blonde and light silver hair scattered against his scarred body, leading down towards the V dip that he still had even at his age. He was certainly rounder now, his stomach more pronounced but he was nowhere near out of shape. The parts of him that used to be pure muscle were now softer as he stepped inside the steamy shower. Still plagued with thoughts of you as he wrapped a soapy hand around his cock.
You’d be the death of him.
You heard the shower begin to run as you pulled the oversized shirt you’d worn to bed up and over your head, leaving you clad in the tiny set of lingerie you’d bought especially. A deep shade of green that matched his hero costume perfectly, catching your reflection in the mirror as you made sure all the straps of it were positioned in the right way, twirling to look at how it looked from behind.
You knew Bakugou always passed by your room before he went to sleep, and with your mother out at work this would be the perfect opportunity to do this. Leaving your bedroom door wide open as you heard the shower turn off from across the hall. Waiting expectantly as the click of the door sounded to indicate Bakugou was leaving the steamy room, turning around so you were facing your headboard as you spread your thighs, moving onto all fours as you heard a choked gasp sound from your bedroom door. Smirking as you turned around innocently, holding your phone in your hands as you pretended to be taking photos of yourself.
“Everything okay, daddy? Did you get lost again?” You smirked at the deep red blush across his cheeks, wide eyes staring at your exposed skin shamelessly as he stood in nothing but a towel. Already seeing the thick meat of his cock beneath beginning to harden, “Your room is down the hall, remember?”
Bakugou’s eyes were focused on the way the small string of fabric clung to your lower lips, disappearing between the curve of your ass as he felt his hips stutter. All it would take would be one finger beneath the fabric to move it to the side, he could probably tear the material off you completely with one harsh tug. But it seemed such a shame to damage it when it was the exact shade of his hero costume.
You had to know what you were doing.
“You doin’ that on purpose, hah?”
“No, daddy. I would never.” You spoke so innocently but your actions were anything but, sitting up and turning around so he got the perfect view of your breasts. Smiling at the way your step-dad’s eyes glazed over, mouth agape as he continued to blatantly ogle you. “If you keep getting lost on the way to your bedroom maybe you should start sleeping with me instead.”
You definitely hadn’t expected his answer.
“Gonna let me sleep in your bed?” You found yourself nodding n. agreement, although you suddenly felt shy. Trying to keep up the bold act as he took a daring step forward, you hadn’t expected him to bite.
“Yeah? Gonna look after your old man.” You gasped when he came towards you, standing at the foot of your bed so you could get a better look at his exposed skin. Still damp from his shower as your eyes mapped out every ridge and scar across his body.
“You gonna sleep with me, daddy?” Bakugou groaned at the implication, you were pure sin.
“Is that what you want?” He asked huskily, your head nodding before he’d even finished the sentence.
Bakugou groaned when he reached out to squeeze one of your breasts through the sheer fabric of your bra, thumbing the fabric as he watched your nipples harden beneath it. Your back arching into his touch as the straps fell off your shoulders, shuffling your knees to come closer to the edge of the bed towards him. Fingers tugging at his towel. He let it drop to the floor shamelessly as you gasped at the sight of his thick, fat cock. He smirked at your reaction, already feeling himself regaining control in the situation after being completely blindsided by you.
“This the biggest one you’ve seen?” Bakugou laughed as you nodded your head, instantly reaching your hand out to wrap around it but he couldn’t let you. With the amount of pent up tension he had in his body because of you, he knew he wouldn’t be able to last long. Instead, grasping your small wrist in his palm as he moved it away. A look of hurt flashing in your features as he shook his head, moving both his large palms to your thighs to pull them out from beneath you, laying you back flat on your bed.
“Gonna let daddy taste this pretty pussy?” He hummed, gliding the back of his knuckles along your covered folds as you rolled your hips into his touch, trying to get him to touch you where you needed it most as he felt just how wet your panties were already.
“Please-” You gasped as Bakugou’s palms grabbed your waist, raising you up and moving you towards your headboard as though you weighed nothing. A sheer indication of his strength as your mattress dipped from his weight as he settled between your thighs.
Fingertips tugging the thin hem of your panties as he pulled them down your thighs, noticing the silvery strings of your slick catching against the fabric and splitting off to stick to your inner thighs. Bakugou’s breath catching in his throat as his eyes met the sight of your naked cunt for the first time. Your folds glistening invitingly as your wetness glistened in the early morning light. Unable to resist running his calloused thumb through them as he split you apart, pressing against your clit before continuing lower. The tip of his thumb pressing against your entrance as he felt just how tight you were. Barely able to fit the expanse of his thumb inside you as he began to circle it, smirking at the way you tried to suck him in.
“Daddy, don’t tease. I can take it-“ You whined, rolling your hips to try and get him inside you.
“You can take it, can you?” Bakugou rasped, smirking at the whine that left your lips when he moved his thumb away from your folds, pressing a gentle kiss to your clit, “‘m not sure you can, little girl.”
Leaning down onto his chest as he curved his large palms around your thighs, spreading you open for him as he blew cold air against your bare cunt. Watching the way your body responded to him as he stared up at you. Half lidded eyes gazing back down at him as your chest heaved in anticipation. Unable to wait any longer as his resolve crumbled, sliding the flat of his tongue along your folds as he gave your cunt a languid lick. Your hips arched off the bed erratically at the sensation, hands immediately weaving into his messy blond hair as you let out a shrill cry. The thin stubble along his jaw scratching against your soft skin roughly, creating a delicious friction that had you begging for more.
Fuck, you were so responsive. He repeated the motion to try and pull more of those sweet sounds from your lips, your nails grazing his scalp as he began to feast on your pretty cunt. Swirling his tongue around your puffy clit before travelling lower, dipping the tip inside your tight entrance.
“Daddy, fuck-“ You whined, your thighs tightening on either side of his head as you tried to keep him pressed against your cunt, “Feels so good-“
“Yeah, sweetheart?” Bakugou groaned, sliding a single finger inside your tight entrance as he began to slurp at your clit. Your inner walls clenched around him immediately, sending a surge of desire directly to his cock. If you felt this tight around one of his fingers, imagine how tight you’d feel around his cock.
You tasted even better than he could’ve ever imagined, the sweetest ambrosia that he would have made deals with the devil to sample.
“Want more, daddy. Please-” You pleaded with him, wanting to feel the force of him stretching you out.
“Sure you can take it, pretty girl?” He smirked against your clit, sucking it between his lips as watched your mouth open in pleasure.
“Yes, please-” You keened as he obliged, pushing a second finger inside your tightness and groaning as he felt the way your body tried to tighten around him.
“You need to relax, Princess. Too damn tight-“ He rasped, scissoring his fingers to try and prepare you for his cock. Wet, lewd squelches filling your room as you writhe beneath him.
His fingers curved towards the spongy spot inside you that you’d never been able to reach with your own. Navigating towards it like he knew exactly how to make you come undone. Something that probably came with years of experience, nothing like the boys you’d been with before who would jab into your tight walls frantically as they tried to speed past the intimate act of foreplay.
“Fuck, daddy. ‘m gonna cum.” You gasped at how fast your climax had washed over you, unused to the sensation as you let out a loud cry. Your toes curling as your thighs squeezed either side of his head, his lips still wrapped around your clit as he worked you through your climax, pulling more of those pretty sounds from your lips.
“Fuck,” Bakugou groaned, moving back from your slit as your juices dribbled from the side of his lips, glistening against his chin as he continued pumping his fingers in and out of your quivering walls as he cherished the sensation.
Licking his lips as he wiped the back of his hand along his chin, offering his slick coated fingers to you as you eagerly sucked them into your mouth. Swirling your tongue around them as you taste yourself on his skin.
Bakugou moving up from between your thighs as he let the fat meat of his cock flop down on your abdomen, the mushroomed head oozing pre as it dribbled against your skin near your belly button. The suggestion that he would be that deep inside you when he fucked you made your abdomen swirl, your empty cunt clenching at the thought.
Tugging the sheer cups of your bra down to let your round breasts spill out. Palming the soft skin as he watched how responsive you were to him. Tweaking your soft nipples between his thumb and forefinger until they pebbled beneath his touch, pulling more sinful sounds from your lips.
His hands moving to your thighs as he began to grind the length of his cock along your sloppy folds, the veins of his cock catching against your puffy clit as he rolled his hips. Watching the way your tits bounced as he ruts himself against you.
“God, you’re so fuckin’ pretty.” He rasped, imagining how much prettier you’d look covered in his cum. Wondering if you’d let him take a photograph after so he’d have something to stroke his cock to at night when he lay in bed with your mother.
“I want you inside me, daddy.”
“Shit,” He groaned when your fingers began to press down on the tip of his cock, trying to catch it against your tight entrance as you angled your hips to get him inside, “I can’t without- Got any condoms in there?”
Bakugou leaned over towards your bedside table, tugging it open as you wrapped your thighs around his waist, your ankles locking behind his back to try and keep him positioned on top of you.
“I’m on the pill, mum said it would be better for college.”
Bakugou felt his cock throb at your words before his nose scrunched in annoyance. The simple idea of any college boys putting their inexperienced hands on you, using you for their perverted gain had him seething. You deserved to be treated better than that, to be looked after. There was nothing you could get from those inexperienced boys that he couldn’t give you. You needed a real man, a man that had the experience, the care and that wouldn’t leave you after a quick fuck.
“Yeah? Been letting those spotty college boys fuck this tight little pussy, have you?” Bakugou snarled, but it was more to find out how far you’d actually gone with anyone before.
“N-no, they’ve wanted to. But I’ve never let them do this-”
Bakugou’s nostrils flared in relief as he felt a pride swell inside him, you’d never let anyone do this but you were letting him. Good. You were his, he’d treat you properly. He’d make sure you enjoyed this.
“Want daddy to make you feel good?” He groaned when he pushed the fat head of his cock against your tight entrance.
“Please, I want it.” You whined when you felt Bakugou ease his hips forward. A dull ache forming between your thighs as he began to split you open on his cock.
“Jesus christ.” He groaned, feeling the way you clenched around him as he slipped inside inch by inch, trying his best not to rut his hips forward and bury himself inside you to the hilt with one thrust, “So fuckin’ tight.”
“It hurts, daddy.” You pouted, Bakugou’s thumb navigating towards your clit in an instant as he began to press sloppy circles against it. Your eyes were glossy as you tried to fight back tears, your lower lip trembling as Bakugou pressed a rough kiss to the side of your knee.
“I know, sweetheart. I know. Gonna make you feel so good soon though.” Bakugou watched the way his cock disappeared inside your tiny walls. Pressing the palm of his hand against your mound to feel the way he was stretching you out.
“You’re so big—“ Your words were innocent, matter-of-fact but you had no idea what they did to him. His hips jerking messily as he buried the final inches inside your tightness, his tip kissing your cervix as the messy hairs at the base of his cock tickled your clit.
“Those college boys ever make you feel this good, hah?” Bakugou grunted, certain he already knew the answer from the way you were clinging to him, eyes rolling back as your nails dug into his wrists as they held your legs apart, “They even make you cum?”
“N-oh,” You gasped as his cock brushed against a certain spot inside you, igniting a sensation you’d never felt before. Bakugou was pleased with the answer, knowing that he would be the only man to make you cum. You were his, and he refused to let anyone else have you.
“Bet that shitty fuckin’ boyfriend of yours wouldn’t even know how to make you cum, would he sweetheart?” Bakugou’s hips snapped against your thighs bruisingly, keeping a frantic pace. His body still aching from his strenuous night shift but he was determined to make you feel good.
He wouldn’t last long, your eager walls clenching around him so perfectly as he split you apart on his cock. He couldn’t remember the last time he’d felt this good, your smaller hands reaching up to wrap around his broad shoulders. Eagerly trying to pull his lips down to yours, meeting in a sloppy kiss as he continued to fuck himself into you.
“Fuck, daddy. Gonna cum-“ You gasped, he’s just so deep inside you. His thick cock catching against every single ridge inside you, pressing against that spot inside you that would have you seeing stars. Your breasts bounced harshly with each roll of his hips, crying out for him as he continued to pound himself against your bruised cervix.
“Do it, sweetheart. Cum for daddy.” He groaned at the way your walls began to flutter around him, crying out as you came undone. Your body quivering as he fucked you through your release, your thighs shaking as he tried to hold on to his climax for longer. Wanting this moment to last as long as possible, but it was difficult with the way you were squeezing his cock. Eagerly trying to milk him of his release as he continued to listen to the sweet sounds he pulled from your lips.
“Shit, ‘m gonna cum.” Bakugou moved to slip out of you, more than content with cumming all over your perfect body but your thighs locked him in. Keeping him buried inside you as his hips faltered, his grip on the back of your thighs bruising as he began to feel the bliss of his orgasm surging through him.
“F-uck, you naughty girl-“ He grunted as he came, spilling thick, white ropes of his cum inside your willing walls. Still convulsing around him as you tried to milk him of his release, his balls lightening as he gave you all he had. Emptying himself inside your tight heat.
Bakugou kept himself sheathed inside you for a moment longer, cherishing the sensation of your tight cunt clenching around him in the after tremors of your climax.
Slowly slipping out of you to see the thick creamy ring of your release coating the base of his cock and his balls, looking towards your stretched cunt to see his pearly cum beginning to seep out of your convulsing walls. Unable to resist pressing a finger against you to push it back inside, blunt nails grazing against your inner walls. Your hands reached for his wrist as you tugged it away from your cunt, pulling it up to your lips as you cleaned the mixture of yours and his release off the digits.
The action causing Bakugou to groan as his spent cock began to throb painfully, already thinking about pushing himself back inside your silky walls.
“You look tired, are you gonna sleep in here with me, daddy?” Tugging on his wrist in an attempt to get him to lay down beside you. His large frame completely covering your own as he pulled your back against his chest, resting his chin on top of your head as he wrapped his muscular arms around you.
“You better wake your old man up before your ma gets home,” He murmured, basking in the scent of radiating from your pillow.
“I will, daddy. Promise.” You wiggled your ass back against his crotch as you got comfortable, the movement causing him to tighten his grip around you to stop you moving.
He’d said it before and he’d say it again, you were going to be the fucking death of him.
