Never Be The Same

Summary:

Unbeknownst to them, Shouto and Enji are hit by a slow acting lust quirk. When the quirk fully kicks in, they are driven to commit acts that their relationship may never recover from.

Notes:

This is a smut and angst fic. Why not make my favorite characters screw and torture them emotionally simultaneously?

I’m way too lazy to write out how Enji and Shouto were hit by the quirk. I was imagining there were out together doing whatever and a kid wanted to play around with their quirk. Said kid hit 2 random people (I’m imaging by touching them both to activate it) not knowing it was Endeavor and his son. Or maybe the kid did know and wanted to cause havoc?

Also, this was written with the aid of NovelAI. I wrote 90-95% and used input from the AI when I got stuck.

I’m a beginner writer, so don’t expect Shakespeare quality here guys.

Work Text:

“Father?” Shouto knocked on his dad’s door. Normally he would never willingly approach his father for anything, but his body felt like it was overheating. It wasn't just the heat that bothered him either. His head felt heavy and his mind was hazy. He tried breathing slowly to calm himself as he waited for his father's response.

“Hmmm,” Shouto heard his father moan lowly. “What is it Shouto?” Enji asked, sounding fully awake.

"I'm hot.” Shouto said, trying the door handle only to find it locked. “Like I’m overheating.”

Shouto heard his father begin to move around and approach the door. It creaked open and there was his father in a tank top and sweatpants. His feet were bare.

“Shout-“ He heard his father begin gruffly before slowly trailing off. "You need to cool down son. Come here." Enji said urgently.

Shouto stepped into his father's room. He could smell his dad's musk permeate the air, along with some other familiar scents, and all those combined made him want to collapse onto the floor. His already hot body seemed to skyrocket in temperature, and his groin throbbed painfully.

Enji Todoroki had been a Hero for decades. His body was ridiculously muscular and fit. Shouto turned to look at his dad, in the moonlight that shined in through the windows. The ache in his groin doubled and his mind went even cloudier. "Don't worry son, I'll take care of you. You can relax."

"Okay..." Shouto murmured. He looked back at his father expectantly, and watched as Enji started taking off his tank top, revealing his muscular chest and stomach underneath.

Shouto felt like drooling. His eyes locked on his father’s sculpted torso, slowly dropping until they hit his father sweatpants. He could see the outline of his father's dick starting to poke out from under the waistband of his pants. Shouto swallowed nervously. His own dick seemed to throb more intensely than before.

Enji smirked at his son as he pushed his tank top over his head, knowing the effect he was having. He started lowering his sweatpants, almost torturously slowly to Shouto, down past his dick, then below his knees, and finally around his ankles, where Enji stepped out of them.

Enji was now totally naked. Shouto swallowed again, his mouth suddenly very dry. A small part of him wanted to bolt for the door but the bigger part of him needed release.

"Shouto, come closer," Enji commanded. Shouto walked up to his father. Enji sat down on his futon and Shouto followed his lead. Enji took Shouto’s face between both of his hands and kissed him, pushing his tongue into his son’s mouth.

It was like a switch being flipped. Shouto invaded his fathers mouth with his tongue, trying to taste every inch of him. His dad’s body heat made him even more turned on, and he couldn’t settle for just kissing anymore. He wanted to touch him and felt a burning desire to have his father touch him too.

Enji pulled away from the kiss and smiled at Shouto, stroking his cheek lovingly. Shouto had never experienced this level of affection from Enji before. He felt even more aroused. Shouto peered at his dad’s erection. He suddenly wanted to know what it tasted and smelled like.

He dropped to his knees and asked Enji, “Can I suck you off?” Shouto was too turned on to feel any shame. He didn't stop to think about how inappropriate what he was asking was.

Enji let out a low moan and slid his hand down Shouto's back before moving to lie flat on his back, spreading his legs. Shouto wasted no time, sliding up between his dad’s legs until he was at face level with Enji’s dick.

He wrapped his hand around his fathers thick shaft and rubbed his thumb across his fathers head. Enji moaned loudly. Shouto licked the tip of his fathers cock, tasting his precum. He started lapping at the tip while stroking the shaft, savoring both his father’s taste and his moans.

Enji reached down and grabbed hold of his son's head, guiding him lower. Shouto lowered his head further until his lips were wrapped around his father’s dick. Shouto wrapped his hands around the shaft and started sucking him off.

Shouto took as much of it into his mouth as he could, but there were still inches left. His tongue snaked around his fathers cock and he felt his dad tense up. He looked up at his dad, seeing his Enji’s head was thrown back.

Shouto bobbed his head up and down while sucking, loving how Enji felt and tasted in his mouth. Encouraged by the sounds his father was making, he sped up. He hollowed his cheeks while playing with Enji’s testicles. It wasn’t long until Enji let out another loud moan and shot his load into his son’s mouth.

Shouto pulled his head back, popping Enji’s dick out of his mouth. As Enji panted and basket in the afterglow, Shouto craved his own release. He’d gotten his father off, it was time for Enji to return the favor.

Shouto had watched enough porn to know that after foreplay came sex. He spat out Enji’s cum onto his hand, kicking his pants off. Shouto’s above average sized dick stood painfully erect. He quickly lubed himself up with Enji’s semen.

He palmed himself through with one hand and with the other started trying to lift one of his dad’s legs. His father’s enormous thighs were too big for him to lift without Enji’s compliance.

“Can you lift your legs up to your chest?” Shouto asked, kneeling between his dad’s legs.

"What?" Enji mumbled, confused.

"I want to fuck you," Shouto said. "With my dick."

Enji froze and looked at his son with wide eyes.

“It‘ll feel good, I swear,” Shouto promised, feeling desperate to get off.

“If you say so,” Enji said doubtfully. There was another pause until Shouto impatiently started trying to push Enji’s legs up himself.

Enji hesitantly raised his legs and Shouto guided his arms beneath his knees. Absurdly, Enji looked cute lying there with his knees to his chest, nervously watching Shouto. Shouto’s gaze dropped to Enji cute little hole. He traced the puckered rim which twitched at the attention.

“Just hold them like that,” Shouto said, prodding his dad’s hole with a cum covered finger. Enji’s breath hitched. Shouto pushed his finger inside of him. Enji gave a soft grunt of surprise. He held his legs as best as he could and Shouto pumped his finger in and out of his father’s tight ass, moaning as he did so. “So tight…” Shouto murmured, pushing another finger in.

Shouto slowly slid his fingers in and out, marveling at the heat and softness of his dad’s insides. With his other hand he slowly stroked his dick, desperate for some release. "Father, you’re really warm...and squishy..."

Enji didn't respond. His breathing was erratic and he wasn't making a sound. Shouto slipped in another finger, pushing his fingers in as deep as he could. Enji’s hips twitched and he gasped. Shouto sped up his movements.

“Uh, uh, uh,” Enji moaned and his dick started rapidly hardening again.

Shouto took that as his cue. "Father," Shouto said, withdrawing his fingers. "I’m going to put it in.” He hurriedly stripped his shirt off and pressed his dick against Enji’s hole. Enji’s body tensed. Shouto pushed forward, slowly forcing himself inside of his father.

"Ah!" Enji exclaimed loudly, his voice cracking. Enji grunted and tipped his head back as Shouto pushed deeper, filling him up.

"Sorry," Shouto apologized, withdrawing halfway from his dad's hole before slowly thrusting in again and again. He knew he should stop and let his dad adjust but he just couldn’t help himself. His father’s ass was gripping his dick so tightly. His entire body was alight with pleasure, he couldn’t stop his hips if he wanted to.

Shouto had the wherewithal to start stroking his father’s dick to increase his pleasure.

"Oh, Shouto… Don’t stop,” Enji moaned, shivering. His dick was pulsing, growing even stiffer.

Then Shouto fucked him harder, trying to match the pace of his thrusts with the stroking of his hand.

The sound of skin slapping and moaning filled the room, and at the very back of his mind Shouto was glad his father’s room was on the opposite side of the estate as his siblings.

"Shouto! Shouto!" Enji gasped out, head lolling in pleasure.

Shouto kept moving, pumping his cock into his Enji’s ass while jerking him off.

"Ah! Ah!" Enji gasped, his hips jerking and his dick throbbing. Enji came, shooting cum onto his chest and clenching even tighter around Shouto’s dick.

Shouto kept thrusting, watching his dad's expression change as he came. He didn't know why, but seeing his dad’s eyes roll back and mouth hang open went straight to his cock. With each thrust he tried to go deeper and deeper, trying to burrow into his father as much as possible.

Shouto groaned as he came, his hips jerking as thick ropes of cum erupted from his dick. When he finally pulled out afterwards, his dick was wet and sticky with cum.

Enji let go of his legs and Shouto crawled onto his fathers chest. His father felt warm and soft, and before long Enji had wrapped both arms around him.

Shouto had never felt this close to his father. It was nice. It was also turning him on again, hardening his dick against his father’s stomach. Shouto felt Enji’s dick hardening too.

“One more time, Shouto?” Enji asked, rubbing his dick against his son.

Shouto hurriedly agreed, climbing off Enji. Enji rolled over onto his hands and knees.

Shouto crawled over to his father, moved behind him and lined himself up. Enji’s back arched, lifting his butt slightly as Shouto guided himself into his father's ass, prying the cheeks apart to get in further. Enji spread his knees further to give his son more access. They both moaned as Shouto sunk in all the way. Shouto stilled, enjoying the way his father’s wet heat twitched and clenched around him.

Enji began to slowly move his hips, pulling forward until Shouto was most of the way out then pushing back until Shouto’s pelvis was flush against Enji’s ass.

Shouto could only gasp out moans as his father took complete control, increasing his pace and pushing back harder and harder. Shouto watched, hypnotized as he slid in and out of his father’s stretched rim.

“Father, you feel so good,” Shouto growled out as he started matching his father’s movements. Suddenly, Shouto needed to hear it from his father too.

“Does it, hah, feel good? Tell me,” Shouto commanded.

“It’s good,” Enji gasped out, “it feels good,” Enji’s body shuddered, hole clenching at the admission.

The two moaned and groaned together, Shouto's cock throbbing inside Enji's tight ass. After several minutes of rough fucking, Enji tightened around him in a vice grip.

“Shouto!” His dad cried out in an almost feminine voice as he came yet again. Enji’s movements slowed as his body shook from the force of his orgasm. Shouto took over, aggressively plowing Enji as he chased his own orgasm.

Shouto growled as he released another load of cum into his father's ass. He slumped over onto Enji’s back, feeling completely exhausted. As Shouto softened he withdrew with an hiss.

Shouto collapsed on the futon beside his dad. Enji lie on his side, throwing an arm over Shouto and stretching himself out. Shouto was asleep before he knew it.

***

Shouto woke up slowly the next morning. He yawned and stretched, throwing the blanket that had been covering him off. Upon opening his eyes, he saw that he wasn’t in his bedroom and he froze. The memories from the previous night came flooding back, and Shouto’s stomach turned. He had… with his own father…

Shouto flung himself away from his father’s futon. He didn’t know where Enji had gone but he needed to leave the room as quickly as possible. His threw on his pajamas, which had been folded and placed beside the futon, and fled the room.

Upon closing the door behind him, Shouto made a mad dash to the bathroom. He sat down on the toilet lid and leaned his forehead against the cool metal of the sink. He tried to breathe as calmly as possible, but it was difficult.

Part of him wanted to throw up and other part wanted to cry. He felt disgusting, dirty. He was a horrible person. He couldn’t believe had done something so depraved and so wrong.

He took a deep breath, glancing into the mirror and freezing at the crusted white substance on his face. His father’s cum. His stomach turned violently and he just barely got the toilet lid up in time to puke up bile. His gagged over and over, even after nothing came up anymore. He wiped his mouth and flushed the toilet.

He thoroughly scrubbed his mouth in front of the sink until all he could taste was his minty toothpaste. When he was done he stripped off all his clothes and jumped in the shower. He washed his body over and over as tears fell and got lost with the shower water.

When he finally felt clean he turned off the shower, dried himself off and threw his wet clothes in the hamper. He put on his robe, which he always kept in the bathroom. He towel dried his hair, not bothering to comb it like he usually did.

He took one final look in the mirror trying to ensure he looked as normal as possible. He took a deep breath and made sure he was calm before leaving the bathroom. He luckily made it to his bedroom without running into his father or one of his siblings. Once he was sure he was alone, he lay down on his futon.

He curled up into a ball, thinking about how much he hated himself for what he'd done. He still couldn’t believe he’d fucked his own father. It was disgusting. He knew logically that he and his father must have been influenced by a quirk. His father had barely acted like himself; the old man had been unnaturally welcoming and affectionate.

Further, Shouto knew that he would never in his right mind approach his father’s room in the middle of the night for anything, let alone sex. He had never looked at Enji in a sexual light prior to last night, when he woke up with a cloudy mind and overcome with lust. Despite knowing all this, he couldn't stop beating himself up over it.

Because despite never lusting after his father before, now that he knew how hot and tight Enji’s hole was, how he clenched and moaned when he was fucked, and how his face contorted in pleasure when he came, Shouto didn’t think he could ever look at Enji normally again.

Shouto felt his dick start filling out again and desperately tried to avoid those thoughts, but memories of the previous night kept flooding his mind. He forced himself to think of disgusting things to make his burgeoning erection go away.

Was he still being affected by the quirk? Why was this turning him on?

His thoughts were interrupted by a knock at the door.

“Shouto? Are you coming to breakfast?” Asked Fuyumi. Shouto startled, he had completely forgotten about that. He wanted to say he wasn’t hungry but he knew he desperately needed a distraction.

“Yes, I'm coming.” He started to get out of his futon, then froze. He didn’t think he could face his father yet, especially not in front of his siblings. “Uh, Fuyumi, is the old man eating with us?”

“He had breakfast in his office,” Fuyumi called, already heading back to the dining room.

Shouto sighed in relief, making himself crawl out of his futon. He dressed and followed Fuyumi to the dining room.

***

After breakfast Shouto busied himself spending time with his siblings, talking to his friends, and watching TV. His day passed pretty quickly and before he knew it, the evening had come. He still hadn’t seen his father. Ever since deciding to atone, Enji had made it a point to spend more time with his kids when he was at home, however Enji had seemingly spent the day locked in his office.

It was clearly because of what happened last night. As Shouto prepared himself for bed he couldn’t help but wonder about his father. He had never once desired Enji’s attention but now he craved at least seeing his father, just to know things wouldn’t be ruined between them forever.

Shouto was returning to the U.A. dorms in the morning and wouldn’t be back at home for a week. If Enji didn’t talk to him by tomorrow morning they wouldn’t talk for several days at the least.

It would have been one thing for Enji to just pretend like nothing had happened, but to avoid Shouto because of this? It made him angry and betrayed. How could they possibly try to repair things if Enji wouldn’t even face him?

As the evening turned to night, Shouto lie in his futon trying to sleep. He had school tomorrow and really should sleep. But he couldn’t. Thoughts of his father kept invading his mind, and eventually he gave up on sleep.

When he checked the time, he saw that it was late enough for his siblings to be asleep. Usually his father went to sleep early as he woke up at the crack of dawn for work. However, Shouto highly doubted he was the only one lying awake thinking about this.

He decided to go confront his father himself. He made his way first to his father’s room.

“Father?” he called from outside the door. There was no answer.

Shouto again knocked on the door and called out. Again, no answer.

He checked the handle, finding the door was unlocked. He slowly pushed the door open enough for him to peer through. The room was empty.

Father must be in his office then. He never left for work without telling whoever was home, so he must be somewhere at the estate.

Shouto headed towards the office, hoping he could find him there.

He could see the lights were on in the office. Shouto knocked and called out, “Father?” Without waiting for a response he started slowly opening the door, relieved to see that is was unlocked.

Enji was sitting behind his desk. There was a glass of water next to him and his laptop was open though the screen was dark.

Shouto crept into the office, closing the door behind him.

“Shouto?” Enji croaked. When Shouto properly looked at his father, he was shocked at what he saw. Enji looked… haunted? He eyes were red and swollen and his face was pale. “Last night- I’m… so sorry!” A tear fell from one of his eyes.

Shouto stood frozen in shock. What was he apologizing for? “What? That was a quirk, it wasn’t you.”

Enji shook his head and wiped his face with his hand. “I should have been able to resist it.”

Shouto felt uncomfortable. He’d never seen his father like this and he didn’t know what to say.

“…we were both hit by that quirk, and we both chose to… have sex,” Shouto cringed internally at saying it out loud and Enji’s entire body trembled for a moment. “And besides, I’m the one who… was inside you.”

Shouto’s stomach flipped saying those words. It was true, but it sounded so wrong.

Enji let out a cross between a whimper and a moan. He recoiled, as if hearing those words was painful to him. Enji turned away and put his hands over his face.

A heavy silence hung between them. Shouto didn’t know what to do, but he couldn’t stand his father’s avoidance any more.

Shouto took a few unsure steps forward and placed a hand on his father's shoulder, "Father, listen-"

Enji pulled away from Shouto, still covering his face.

Shouto was getting angry now. While Enji had hid himself away in his office all day, Shouto was doing to best to move forward, forced to push past everything. Even now, Shouto was confronting what happened while Enji cowered. Why did his father think he had the right to hide himself away and cut Shouto off?

“Look at me!” Shouto grabbed one of his fathers wrists and ripped it away from his face. “So, what now? We just never talk again?”

Enji didn't respond.

"Answer me!"

Shouto could feel tears starting to well in his eyes but refused to allow himself to cry. His emotions were so conflicted. He wanted to scream, to shout, to cry, to punch something, anything. All he could do was stand there and stare at his father.

Enji finally dropped his hands and looked up at his son. His eyes were watery and sad. "Shouto,” Enji began sadly, “I’m sorry.”

Shouto didn't respond.

"Please just… go back to your room, I'll see you in the morning." Enji said quietly, looking down at the floor.

Shouto turned around and stormed out of the office, slamming the door behind him.
