Denki's Dad

Summary:

Now, Izuku loved to see him in his normal attire. A suit, tie... and tight slacks but there was something about how he looked in shorts or the grey sweatpants. God, it had him drooling instantly. Prom was a shitty day for him. Izuku was on the popular side, and he was nice to every girl that asked him to prom, but it felt like he was cheating on Denki’s dad.

Not that he’s madly in love with the guy or anything.

He swore to get his shit together when they went off to college. Fresh slate. No super sexy older blonde to worry about... WRONG!

He still saw the man every week.

Sometimes twice a week.

 “Your house or mine?” Izuku opened his mouth, but Denki shoved his shoulder lightly, “I know, mine!” Well, he wasn’t wrong.

Denki and he have been best friends for years. They grew up in the same neighborhood, went to the same schools and now were at the same university. His mom loved to say they were brothers from another mother.

But he didn’t want that.

Izuku’s been in love with Denki’s dad since he was seven and that crush never went away. Nope. It grew throughout high school when he realized that he was gay. Well, gay for one man only.

 “Shut up.” He laughed, nudging the shorter blonde back, “My house is boring! You have a personal chef that feeds us snacks and the newest video games. We can even hang out in the pool!”

Denki laughed along with him, “Not my fault my dad is amazing!” He grinned, “Remember prom?”

 “Ugh! Don’t remind me!”

 “Hey!” Denki smiled, “You got to stay over the whole weekend!” That may be true but the only thing he remembered about prom was the raging boner he had the entire night because Denki’s dad wore socks with sandals... and shorts.

Shorts!

Now, Izuku loved to see him in his normal attire. A suit, tie... and tight slacks but there was something about how he looked in shorts or the grey sweatpants. God, it had him drooling instantly. Prom was a shitty day for him. Izuku was on the popular side, and he was nice to every girl that asked him to prom, but it felt like he was cheating on Denki’s dad.

Not that he’s madly in love with the guy or anything.

He swore to get his shit together when they went off to college. Fresh slate. No super sexy older blonde to worry about... WRONG!

He still saw the man every week.

Sometimes twice a week.

 “You broke so many hearts that day.”

Izuku rolled his green eyes, gripping the strap of his yellow backpack tightly, “I told you I was gay, man, what do you want me to do? Lead one of the poor girls on?”

Denki slugged him in the arm, “That’s not what I’m sayin’,” He huffed, “I just don’t know why you didn’t ask out a guy or something.”

Cause I’m in love with your dad and that thought stabs my heart

Yeah. He’s fine.

 “How is your dad doing anyways?” He asked cautiously.

The blonde shrugged, “He’s alright—no happier. Mom was a dick to him a lot so since the divorce, he’s chilled out.” Izuku had so many wet dreams of that man, it was ridiculous. “Anywho, I need a favor.”

He bit back a loud groan and looked down at his friend, “You and favors suck, Denks.” Denki stuck out his lower lip, whining slightly like a dang puppy, “What, doggie?”

 “You know how my dad is and his house rules,” Great, he didn’t like where this was going, “Hitoshi is throwing a party and I’m going!” One thing about Denki’s dad was that if he lived under his roof, he lived by his rules. Not a lot of rules but Hitoshi was known for drugs. Pot mostly and Denki’s dad hated drugs.

 “Deeeenki!”

 “C’mon, Zu! My dad loves you and he’ll believe anything you say!” The dumb blonde batted his eyelashes up at him, “Please! I’ll owe you big time! Like super big!”

 “And what could you possibly do for me?”

Denki huffed, “Well, Mr. Perfect with perfect grades and a free ride to college with your massive brain power,” Izuku rolled his eyes and waited for him to continue, “I don’t know! But I can find something just please! My dad thinks you walk on water!”

Izuku sighed, “Fine. Just this once but I’m not covering for you again.”

 “I owe you big time, my dude.”

 “Yeah, yeah, just tell Hitoshi you like him already, kay? The thirsting after him is getting old.” Ha! He’s one to talk. Denki just laughed and opened the front door to his home. The inside looked like they took it right out of a magazine. Picture perfect.

 “I’m home!” Denki called out, dropping his bag by the door, “Zuku is with me!”

Izuku set his bag down and followed the blonde through the house to the kitchen. His heart lurched and his breath hitched at the very sight of Denki’s dad, standing in front of the stove. Did he mention this man was blessed with amazing hands? Damn, watching him cook was almost better than watching porn.

 “Welcome home, son, Izuku, how was finals?” Katsuki Bakugo asked. Katsuki was a—there was no words to describe his stunning god like body. Izuku wanted nothing more than to run his hands over his pale smooth skin and drown in his voice. Maybe Izuku had a voice kink. Praise kink? The first time Katsuki told Denki that he did a good job, he almost came in his pants.

Nah, he so did.

Denki groaned, pulling him from his thoughts, “They sucked but Zu probably got straight A’s again!”

 “I even tutored you, Denks,” He chuckled sheepishly, running a hand through his curls, “I bet you did great.”

Katsuki turned around with a dish towel in his hands, “If you have the attitude of failing, then you’ll fail.” Crimson red eyes looked between them, “I’m assuming you will be spending the night, Izuku?”

In your bed, please?

 “Um, yes, Mr. Bakugo, if that’s alright.”

 “Katsuki. We’ve talked about this. I’m forty five, not eighty. Mr. Bakugo is my father.” Katsuki gave him a hard look before turning to his son, “Are you going to order pizza?”

Was it hot in here?

It felt like his whole body was smoldering. Maybe he was going to explode! Jesus Christ! He really needed to get this crush—undying love—under control before he loses his ever loving mind and die... Dying may be the only option.


 “Alright, my dude! I will be back before the sun comes up.” Denki gave him a two finger salute and hopped out the window. Izuku huffed, flopping back on the bed. Why the hell did he agree to this?

Because he can’t say no to Denki.

Groaning, he sat back up and hopped to his feet, “Denki’s dad is probably in bed, so I’ll just go for a nice swim. Yup. Swim and daydream. Drown. All those were good ideas. Thankfully, he kept a pair of swim trunks at Denki’s for the spur of the moment swim time.

Stripping down, he pulled the blue swim trunks over his legs and snapped the waist band slightly, “Time to drown.” He mumbled. The house was so quiet, he could hear a pin drop probably upstairs from the pool house.

Izuku stepped into the pool house, closing the door as softly as he could. The fresh smell of chlorine surrounded him and the soft sound of rushing water from the built in waterfall, relaxed his mind and core. Swimming was a big thing for him. His mom always took him on the weekends. He’d even spend an hour in the bath.

Mom called him her little merman.

 “Ah, coming for a late night swim?” Izuku stiffened, staring at the door with wide eyes. No. No fucking way. Why was Denki’s dad in the pool?! He normally went to bed early! Like eight! It was one in the morning! “Izuku?”

He forced a smile as he turned around, “O-Oh, sorry, Mr. B-Bakugo! I-I didn’t know—I didn’t t-think—” He should just shut his mouth now.

The older man crooked his finger, calling him. Izuku couldn’t stop his feet from following the silent command. He slowly made his way to the pool and sat down on the edge, putting his feet in the warm water. Katsuki slipped under the water.

Izuku knew that he should get up and leave. Leave and never come back but when the man broke the surface between his parted legs, his heart held him in place.

 “Why are you up so late?” He whispered softly, “A growing boy like you needs sleep to keep that brain going.”

Boy.

Izuku was twenty three, he was a man.

 “Is that so?” Katsuki’s red eyes lit up the low lit room, “Are you a man, Iz-u-ku?” Fuck him and his mumbles!

 “I’m t-twenty three, Mr. B-Bakug—” A finger pressed lightly to his lips.

Katsuki scuffed, “Do you like to make me feel old? It’s Katsuki... or would you prefer daddy?” Izuku’s green eyes grew comically wide, “You think I wouldn’t notice? The lingering looks. How my son is never invited over to your house? The way you stutter around me?

 “Now, I asked you a question, Izuku.” The finger on his lips, lifted slightly but only to run along his lower lip, “What would you prefer?”

Izuku stared down at the older man in awe. If he was dreaming at this point, he didn’t want to wake up. “D-Daddy.”

 “What a good boy.” Katsuki cooed sweetly. Suddenly warm strong hands found his hips and lifted him just enough to pull him into the pool. Izuku yelped, wrapping his legs around the taller man’s waist and arms around his neck. “You’re so cute, baby.” He shivered. Katsuki chuckled softly in his ear before running his teeth along his ear, “So perfect.”

There was no way to describe the feeling in his chest. One second, he thought his heart was going to explode and another second it was melting in pure bliss. The water lapped over his shoulders making him tighten his grip on the blonde.

 “I’m not going to drop you, sweet boy but we need to get these trunks off you.” Katsuki paused, waiting for him to answer. How the hell could he say no? He’s wanted—no craved this for years! Nodding slightly, he buried his face in Katsuki’s shoulder. The man didn’t hesitate to strip off his swim trunks. He inhaled sharply as he wrapped his legs around his waist but this time, he could feel Katsuki’s bare cock against his own. “I don’t swim with clothes on. It’s constricting.”

Izuku moaned lightly, grinding his hard erection against the older man’s. Vaguely a thought ran through his head that this was Denki’s dad and he should not be doing this. He grew up with Denki, he loved Denki like the brother he never had and—

 “You sure know how to tease a man, don’t you?” Katsuki whispered, “Walking around my house shirtless... sometimes in just your boxers.” Strong fingers dipped between his ass cheeks and circled his rim lightly. “Your big fat ass sitting on my couch when the only place you should be fucking sitting is my lap.” And the finger pushed inside him.

 “I’m going to leave you wanting, begging—every time you come over, you’ll be thinking of me. When you spend the night, you’ll want nothing more than to find me so I can give you want you deserve.” Izuku moaned loudly as one finger turned into three. He couldn’t even think about anything else but the man holding him—finger fucking him.

Katsuki kissed along his jawline and down his neck, “I’m going to make you mine, baby boy. My sweet good boy. Mark you, love you, fill you full of my cum.”

 “Y-Yes!” He managed to say. The hot coils in his stomach were already burning before he could even say anything, he came hard on his fingers. “I-I’m sorry! I s-sorry daddy.” He mumbled over and over again.

Katsuki chuckled softly, kissing his cheek, “You did so good, baby, just how I wanted you.” Izuku sagged against him as he slowly came down from his high, “So pretty Izuku... but we’re not done.” That’s all the warning he got. Katsuki lined up the head of his huge cock with his hole and thrusted up, sliding to the hilt.

Izuku choked on his scream.

God, no dildo has ever filled or reached so deep before. The water rippled around them with each thrust as his body bounced against him. Izuku dropped his head back fighting the waves of overstimulation and fresh new pleasure. Katsuki knew that the hell he was doing. That man hit his prostate head on with no fault. His walls couldn’t stop clenching down to keep the monster inside him each time he pulled out to thrust back in.

 “D-Daddy!” He cried, cumming over his chest. The water washed his body of the sticky mess. He tightened his grip on Katsuki’s shoulders, “N-No more!”

Katsuki shut him up with a deep, hungry kiss. His tongue licked along the roof of his mouth, tangling with his tongue and Izuku realized that he was just along for the ride. Daddy had all the control... and he was more than happy to give it to him.

 “Such a perfect slut...” He groaned loudly, “Taking what daddy gives you.” Katsuki’s hips sputtered slightly before giving a final thrust home and coming deeply inside him. Izuku came instantly for a third time. He heard Katsuki speaking but he slipped into darkness completely boneless.

….

..

.

Izuku rolled over, groaning. His body hurt... especially his ass which was odd since it was all a dream. Someone snorted loudly next to him and his... pillow shook under him, “If you think that was a fucking dream then damn, baby, you have a wild imagination.”

Oh. Fuck.

 “Sorry if I was a little rough. Hand just doesn’t cut it anymore.” Izuku slowly lifted his eyes. Green met red. “Hey sweet boy.” Izuku blinked a few times, waiting for him to wake up but nothing. Katsuki was still there, naked underneath him... and oh, he was naked too.

 “T-That—We did—oh no!” He tripped over his tongue. “Denki!”

Katsuki stared at him, fondly, “You are just too damn cute.” He laughed, “If you’re worried about Denki, don’t be. That kid is a damn freak so you and me ain’t going to freak him out.”

 “You're his dad!” He protested urgently.

 “And?” Katsuki deadpanned, raising a perfectly groomed eyebrow, “Do you really think that Denki hasn’t noticed? You’re pretty obvious.”

Izuku pouted and bit down harshly on his wobbling lip, “B-But—” Damn the crybaby gene inside him. He felt terrible! He just lost his best friend because he couldn’t control his dick for once in his life! Tears became streaming down his cheeks, “I-I’m so—sorry!” He cried.

Katsuki frowned slightly, “Baby, no one is mad or finds you gross. You can’t help who you fall in love with.” Izuku dropped his face down to the bare chest and cried. It was all too much too fast. His mind was racing and scrambling to find some logic that made any sense.

Katsuki held him tightly, rubbing his back and whispering sweet words in his ear. It felt like hours until he finally calmed down and peeled himself away from the man.

 “I...” He moved to the end of the bed with his back to the other man, “I-I do... love you... but—”

 “I can already hear it.” Katsuki interrupted, “’I’m twenty three and you’re forty something’ or ‘won’t you be embarrassed of me’ or ‘Denki will hate me’. Zu, if I didn’t think this could work, I wouldn’t have fucked you until you passed the hell out, bring you to my bed and hold you all night long. I wouldn’t have let your eyes linger as long as they did. I wouldn’t have let you come over if I knew it wouldn’t have worked.

 “There’re fuckers out there who are nineteen dating seventy year olds for money.” Katsuki said with an eye roll, “I highly doubt you are looking for a sugar daddy. You’re too smart for that BS.” Izuku stared down at his hands, twisting his fingers together, “I’ve liked you since you were nineteen—aint cause you smokin’ hot—but because you actually gave a shit when my ex wife cheated. You made me feel... live and loved and I want that with you.

 “I want to be fucking with you.”

Izuku swallowed down his tears, “A-And Denki?” He whispered softly. “I-It’ll look bad...”

 “Fuck Denki.” Izuku whipped around to find the man grinning, “Just kidding but no damn joke, he ain’t gonna care as long as he still gets time with you.”

Nodding a little, he got on his hands and knees, crawling up the mattress until he was straddling the blonde’s lap, “T-Then... I want to be with you.”

 “Thank fuck!”


 “So...” Izuku looked up from his bowl of cereal, meeting a pair of golden eyes, “when can I start calling you step daddy?”

Izuku choked on his bite of cereal, coughing harshly to clear his windpipe, “F-Fuck D-Denki!” Denki laughed, throwing his head back, “That’s not allowed!”

 “You’re the one fucking my dad!” He grinned, “I’m cool with it, man, I’ve never seen my dad this happy or you for that matter so... as long as you both are happy, I’m happy.”

 “It’s... not weird?”

Denki laughed again, shaking his blonde head, “Nah. I let Hito do all kinds of weird shit to me. Kinks are cool. Just don’t hurt him, kay?” Izuku nodded firmly.

I’m in love with Denki’s dad... and he’s all mine.
