A/n: Reader is over 18!!! Bakugo is also aged up. I haven't written smut in a while so please bare with me.

At approximately midnight, the front door opening startled you from your bed, where you had been engrossed in using your mobile phone. Your stepfather, Bakugo, had returned home after a long day working as a hero, leaving you to your own devices in the house while your mother was away on a business trip. As you made your way downstairs, you noticed Bakugo sprawled out on the couch, his legs apart, clutching a beer in one hand and taking continuous sips from it. Exhausted from his day at work, his focus was fixed on the television, his tired eyes struggling to stay open. He groaned and reclined against the couch, taking another bitter sip from his beer.

As you descended the staircase intending to annoy him, you were taken aback to find him already indulging in his usual nightly ritual of drinking. "Beer? Really?" you exclaimed, unable to hide your disdain as you reached the bottom step. Bakugo's head snapped towards you upon hearing your voice, clearly startled by your presence. He grumbled, placing the beer on the coffee table and directing his focus towards me. "What on earth are you still doing awake, you little brat? Shouldn't you be fast asleep by now?" he inquired, his tone tinged with annoyance.

"Why the fuck do you care?" you snapped, storming off towards the kitchen. You could feel his gaze burning into your back. "What fuck did you just say" he demanded, placing his drink down forcefully. "You heard me, old man. Has your hearing gone to shit?" you hissed back. He followed you into the kitchen, his anger hot on your heels, and slammed his hand down on the counter. "Y/n, I won't tolerate this attitude," he said, attempting to be the mature one and reason with you, but you couldn't care less.

Ever since you and your mom moved in with Bakugo, you've had a major problem with his behavior. He constantly drinks beer, lounges on the couch, and never lifts a finger to help. You're always the one cleaning and cooking when your mom isn't around. And when she is, she takes over and cleans the entire house. She doesn't mind that Bakugo doesn't contribute because, according to her, he's the "man of the house" and deserves to relax after a hard day's work. It's infuriating because your mom works just as hard. So, in retaliation, you've been treating him with utter disrespect for months, all while pretending to be innocent in front of your mom.

Yeah, he may take care of you and occasionally treat you to meals, but that doesn't make up for the fact that you have to clean up after his friends when they come over and leave a mess of beer cans everywhere. You've reached your limit and want to put an end to it.

"Oh, did I hurt your feelings old man?" you taunted, a mischievous smile playing on your lips. Bakugo's irritation grew evident as you continued to provoke him. He straightened his posture, crossing his arms defiantly. "Don't think you can outsmart me, kid. I may be your stepfather, but I still have the responsibility to discipline you," he grumbled, his voice filled with a rough edge. Approaching you, he loomed over your smaller frame. "Hand over your phone and go to your room now."

With a defiant smirk, you mirrored his stance and crossed your arms. "You can't force me, you know. Just because you're screwing my mom doesn't automatically make you my dad," you teased, tilting your head playfully.

You defiantly smirked at him, causing his frustration to escalate. He took a step towards you, his imposing figure casting a shadow over you. "So, that's how it's gonna be, huh? You think you can treat me like shit?" he growled, his voice dripping with intensity. He reached out and firmly grasped your arm, not too forcefully but enough to make his point. "Listen up, you imbecile. You're not going to come out on top in this situation. Say whatever you want, but it'll come back to haunt you," he warned, his grip tightening slightly as a subtle threat.

You rolled your eyes, unimpressed by his display. "Oh, cry me a river," you scoffed. "What exactly do you think you can do?" Bakugo's eyes narrowed, annoyance flickering across his face. He tightened his hold on your arm, asserting his physical dominance. "Don't push me, you fool," he muttered, his voice low and menacing.

"Let go of me!" you snapped, attempting to break free from his grasp. "Ouch!" He leaned in closer, his face mere inches away from yours. "Am I too much for a weakling like you? Fine. But remember, I always come out on top," he whispered, his breath grazing your ear.

You stood frozen, feeling his breath on your skin. "Don't call me weak, you old hag," you retorted, refusing to back down.

Bakugo's eyes narrow even further, a spark of anger flashing in them as he hears your defiant words. He releases your arm, his hand balling into a fist at his side. "You want to challenge me, huh? Fine, brat. Get ready to learn your place," he growls. Without warning, he grabs you by the waist, forcefully pinning you against the wall. Your eyes widen as his face comes dangerously close to yours. "What do you think you're doing, idiot?" You snap. Bakugo's grip tightens on your waist, his knee pressing against your core. Unfortunately, you're only wearing an oversized shirt and panties, causing your shirt to ride up. "I'm doing what needs to be done, brat," he replies, his voice low and commanding. He leans in closer, his breath grazing your skin. "You want to challenge me? Do you want to play this game? Well, be careful what you wish for," he murmurs in a husky tone. His hand trails up your side, his touch firm and possessive. "I'll teach you how to respect your elders," he adds, his voice filled with a mix of dominance and desire.

"Don't touch me," you grit through your teeth before spitting in his face. His eyes widen in surprise as the spit lands on his cheek. His grip on your waist tightens even further, his knee pressing higher against your clothed area. He wipes the spit off his face with the back of his hand, his jaw clenched tightly. "You insolent brat," he snarls, his voice dripping with venom. In a swift, sudden motion, he grabs a handful of your hair, his grip painfully tight. "You think you can disrespect me like that? Think again," he growls, his tone filled with anger and dominance. You yelp in pain as you try to pry his hands off of you. "You're hurting me, you asshole!" you yell, tears welling up in your eyes.

Bakugo's grip on your hair tightens even more, his anger escalating as he hears your words. His piercing gaze locks onto yours, his voice a low rumble filled with a mix of frustration and dominance. "Good. Perhaps a little discomfort will serve as a reminder of your place," he declares, his words tinged with a hint of sadistic pleasure. "Remember, I'm the one who takes care of you. I'm the one who watches out for you. And I won't tolerate any disrespect," he asserts, his voice resonating with commanding authority. "Kiss my ass," you retorted, a tear streaming down your face from the forceful grip on your hair.

"Naughty girls like you need to be taught a lesson," he grumbles. Without warning, he pulls your panties to the side and forcefully inserts two fingers inside your aching pussy. "What the fuck!" you exclaim, pushing against his shoulders and squirming under his touch. He remains silent, holding you down as he thrusts his fingers in and out of you faster and faster, causing you to grow wet with desire. "Stop it, you asshole," you snap before he yanks your hair, tilting your head to the side and planting rough kisses on your exposed neck. "If you want me to stop, why are you grinding your hips against my fingers?" he smirks against your skin. You hadn't even realized that your hips were moving; you were so starved for touch that you would do anything for any form of contact.

"That doesn't mean I like it" you retorted, your voice laced with defiance as the pleasure surged through your body. Desperate to resist his advances, you clutched onto his shoulder, determined to deny him the satisfaction he sought. But deep down, you craved the sensation that awaited when he hit that sweet spot. Your breath hitched as your hips instinctively moved in sync with his skilled fingers. "Please, Bakugo, we can't," you pleaded, knowing it was wrong but unable to resist the intoxicating pleasure. "Do you want me to stop?" he growled in your ear, his fingers teasingly slow, causing you to moan in response. "Damn it," you gasped. "Are you sure you want me to stop?" he questioned, his voice dripping with dominance. "Your body tells a different story. Look at how helpless you are under my touch," he declared, his veiny hands gripping your neck, choking you, pinning you against the wall. Trembling, you whimpered, your desire for his touch finally overpowering your resistance.

"Please, don't stop. Keep going," you managed to utter. Bakugo smirked, crashing his lips onto yours, the eagerness consuming you as he fingered you with fervor, the wet sounds mingling with your moans. "That's what I thought, you slut," he murmured against your lips, sending shivers down your spine. Your walls clenched around his thick fingers, signaling your impending climax. Just as you were about to surrender to ecstasy, he abruptly withdrew his fingers. "N-no! Why would you do that?" you whined, your hips still rocking, craving the sensation of fullness. "Only good girls get to come, and you haven't been behaving, have you?" he taunted, wearing a smug smirk.

"I'm sorry! I promise to behave, just please let me cum," you pleaded, clutching onto his shirt. "Please," you pouted softly. "I'll be good," you said, tears welling up in your eyes, desperate to reach your climax. Bakugo chuckled and gave you a quick kiss, wiping away your tears. "Fine, but how about you cum on my dick instead?' he smirked. You eagerly nodded in agreement. "Please," you begged. Without hesitation, Bakugo bent you over the kitchen island and swiftly pulled down your drenched panties. As he pulled his pants down, his hard cock sprung out. He smirked as he stroked himself, taking in the sight of your bent-over form. "So desperate for my cock, huh" he chuckled, teasing your entrance with the tip. "I'm not in the mood for teasing, Katsuki. Just fuck me," you whined as you pressed yourself against him. And that's exactly what he did. Once you finished your little rant, he shoved his cock inside you, making you gasp and quickly shut up.

He started moving slowly at first, his hands gripping your hips as he gradually picked up speed. You gripped the counter, crying out with pleasure as his cock hit all the right spots and filled you perfectly. "Katsuki," you moaned as he started slamming into you, the sound of skin slapping filling the room along with your moans. "You like that, you slut?" he asked, grabbing your hair and pulling you back against his chest, admiring your face as you enjoyed being pounded. "Answer me," he growled, pulling your hair again. "I-I love it so much," you whimpered as his pace never once slowed. But just as you both heard the front door opening, he slowed down and whispered in your ear, "Stay quiet."

He continued to fuck your pussy behind the counter when your mom walked in. She enters the room, completely unaware of what's happening, and greets both of you with a smile. You try your best to maintain your composure, returning the smile. "Mom," you say, "You're back home early from your trip," leaning on the counter with Katsuki standing behind you. "Oh yeah, the trip got cut short. My boss suddenly got sick," she explains, placing her suitcase down. Gripping the counter tightly, Bakugo hits your sweet spot repeatedly, causing your legs to weaken and a soft whimper to escape your lips. "Oh, that's unfortunate," you respond, earning a tight squeeze from him, silently urging you to control yourself. "Yeah, we had three days left, but things happen," she laughs, removing her blazer. "What are you two doing up? I thought you'd both be sleeping at this hour."

"O-oh, I couldn't sleep. I had too much caffeine before bedtime," you laugh, trying to hide your moan. "I've told her countless times to cut back on caffeine, and now she's wide awake," Bakugo chuckles as he continues to pleasure you. "You need to work on that, Y/n. It's not good for you," your mom advises before heading towards the stairs. "Well, I'm tired. I'm going to bed. Don't stay up too late," she smiles. "Don't worry, we won't," Bakugo assures her, leaving you unable to utter a word as you teeter on the brink of orgasm.

"Goodnight," she murmured before retreating to her room. Bakugo waited until he heard the door close before increasing his pace, his hips snapping against yours, causing your ass to jiggle with each thrust. You couldn't hold back anymore, letting out a moan as tears sprang to your eyes from trying to suppress your pleasure in front of your mother.

"Such a good girl," he growled, praising you. "You behaved so well for me," he chuckled as he relentlessly pounded into you. You whimpered and gripped onto the counter, moaning loudly. 'You can cum, baby. You deserve it," he encouraged, and with his words, your body shook with ecstasy. As Bakugo continued to fuck you, he finally pulled out and came all over your ass. You rested your upper body on the counter, completely drained and your legs about to give out.

He grabbed a napkin and gently cleaned you up, his touch soothing against your sensitive skin. "Want… more?" you managed to utter, looking up at him with pleading eyes. "More?" he asked, a surprised smirk playing on his lips. "You think you can handle it?" You nodded eagerly, your desire evident. "Yes, please. I need you inside me," you whimpered, slowly rising to your feet.

"Fine. But only because you were well-behaved,'" he chuckles before scooping you up and carrying you to the couch. He sets you down on your back and climbs on top of you. He gazes down at your exhausted form as you grind your hips, rubbing your wet pussy against his hard cock. "Fuck," he growls before kissing you deeply, his hands finding their way to your throbbing center. "Don't come crying to me tomorrow about being tired," he teases. You grin against his lips. "I won't. Now just fuck me already."
