Chapter Text

Every day felt like an even better version of the next, atleast for Beam it did.

Following around his favorite person in the entire world was his #1 favorite activity, although he could tell the other man didn’t like it as much as he did, it’s the moment that counts, it almost reminded him of the small furry creatures known as dogs. He wouldn’t mind if Denji made him wear a collar and leash to keep the shark-devil from going far, in fact, it’ll just make him want to have a reason to stick closer to Denji than usual.

The pair turned a corner as they made their way inside of a local cafe, a few people were inside already, small chattering along with the sound of clanking from behind the counter. Looking up from the ground his body was submerged in he could see his ‘best friend’  smiling while tidying himself up, he quickly did a breath check and a smell check as he popped a mint in his mouth. ‘Maybe it’s for good measures,’ the shark thought to himself as Denji looked below him, his smile turning into that of disgust upon making eye contact? Face to face? Whatever, Beam didn’t really have eyes so he doesn’t blame him. His smile was all he needed.

“Beam, go find a table.” There was a hint of annoyance in Denji’s voice, Beam wasn’t upset, even though he wanted to be, he kept smiling, “Yes Maste-” “Denji, just say Denji.” The other boy groaned as his hands pinched the bridge of his nose, “Just go.”

Beam quickly submerged so he could make his way to the bathroom stalls, he opened a briefcase to reveal the plain white shirt with black pants and shoes.

“Makima told me to put this on if me and Denji go somewhere public. Denji doesn’t want me near him though..” Beam's voice quivered slightly as the feeling of sorrow made his head lean down slightly. “Am I just in the way..” He knew the pattern Denji did, after hours of patrolling the boy would go to a certain cafe to meet a lady, she did smell great, but there was something else that made Beam worry about his crush's safety.

‘Crush!?’ Beam blushed as he put his hands on his face, “Lord Denji would never see me the same way!” He hit himself in the head while bringing his legs close towards his face, “Denji do deserve her.. He wants a woman..” The memory of getting punched in the face plays in his head as his friend.

“Gross! I’m not into dudes!”

What Beam thought was only an hour being in the bathroom turned out to be longer as Denji walked inside, “Where the hell is Beam..” He grumbled while whipping his junk out to take a piss at the urinal, he looked up towards the light while smiling to himself, “Can’t believe Reze touched my hand!” He did a little leg dance while shaking his dick to get the rest of the pee out. Putting his dick back in and walking over to the sink he makes an abrupt stop, “But what if Makima finds out…Ugh!” He plants his head onto the marble sink while flicking the knob to turn on. 

“Where the fuck is Beaam!” 

Upon hearing his name the shark fiend woke up from his position in the stall, not his best sleeping spot but maybe tiredness got the best of him.

Denji turned around towards the stall, “Is somebody taking a dump?” He scrunched his nose at the thought until somebody came walking out, the shark fiend who didn’t notice the chainsaw man presence yet looked different from before. “Beam.” Denji called out as the shark snout pointed upwards towards him, “Oh. Oh! M-ma- C- Denji! Hi,” Beam was a jumbled mess, to be found not only at his lowest point but also by the highest person he respected was not the way he wanted to be seen currently.

He needed to get away.

“Uh. I’m going to go Denji!” He was quick to submerged before the halfling got the chance to stop him, “Wuh da fuck was that ‘bout..” Another groan escaped his mouth as he began his journey home.

“People are weird man..”

—--------

Beam wasn’t the brightest, he had to admit, but right now something else was happening, flashes from his human life began making its way into his head, feelings he never knew existed clashing with his current ones. And two that may describe his feelings for Denji.

Lust and Love.

Beam's heart was beating fast, his body was in overdrive, “Loving Denji! What!?” Beam flopped into the pool he found as he let his body float to the top, rolling over so his head was pointed towards the sky above him, “Do I really love Denji..?” 

He knew Devils were able to love, love between Devils held no bonds really, sex didn’t matter, origin sometimes did, time, place, and connections never really played any parts when it came to the love between two Devils. So why did it feel so wrong falling for Denji? Could it be because the boy was the Chainsaw Devil? The one who was deemed the ‘Hero of Hell’, Beam heard his engine before, back in hell, he would be lying if he said the sound didn’t turn him on.

“What!” Beam's body tried sitting up but he forgot he was in a pool so for a second he tried remembering how to properly swim.

“Turning me on… Fuuuck!” Beam climbed out the water as he felt something new occurring, “Denji… What is this feeling..” Beam whined as his hands trailed down his abs towards his trunks, something was bulging. Beam caressed his hands over the foreign object, “I-is that my d-dick!?” The fiend never knew it could get hard before, he knew humans and devils had sex, but he never experienced such a feeling himself, atleast, not in this lifetime. He moaned as he was now on his back while rubbing his cock up and down through the trunks, the wetness clinging onto his skin, “Master..” Beam couldn’t help whispering the man's name as he thought of seeing the other boy shirtless, sharp teeth followed by pink nipples, yellow eyes that pierced into his soul, “Master..!” Beam felt a strong sensation as he began to move his hips as he cock grinded into his hand.

Newer images of Denji’s tongue licking Beam’s nipples along with rubbing his own cock flashed into the shark’s mind as he bit his lip.

Was this the lust that he heard of in his lifetime before Makima ‘saved’ him?

The sensation got stronger, he felt something building up, “Denji!” He whined as his cock spurted whatever fluids into his trunk, some even making its way through the material, his toes curled tightly as he arched his back, “Denji!” Beam gripped his cock as the fluids continued spilling out, he wanted to see what it was, so with quick succession he lowered his trunks as the tip of his cock was reveal, the foreskin was slightly pulled back as he watched white liquid shoot from the hole he thought was meant for peeing.

“W-what is this!” He moaned out while pulling the trunks all the way off, his body was limp while breathing heavily, the content was done spewing out of his dick, his tongue hung out of his mouth. “Master Denji.. I’m sorry.” Beam sniffled, the feeling of sorrow from early coming back in the worst way possible. “I’m such a whore. Denji would be disgusted if he knew..! He would think I’m a freak!” The shark clenched his fist while pulling himself into the pool water, allowing for his body to float to the bottom and allow for the world around himself to fade out.

—-----------

“It seems as if the Public Safety can’t seem to contact the Shark-Fiend, Aki and Denji, you’re required to find him and bring him here, if he has disbanded from his position then please let me know.” Makima’s eyes were filled with nothing as she stared at the two hunters, making them both nod.

For some reason there was a tracker on Beam, neither of the two questioned why or when it was put on the fiend, but it took them to some motel on the outskirts.

“I’m not quite fond of the shark-fiend, I’ll wait out here in case anything happens.” Aki pointed towards the set of chairs and tables while Denji gave him his usual unsurprised expression.

Denji found himself walking towards the pool of the motel- not surprising, they’re after a shark after all- he glanced around the patio and saw nobody, “Beam!” He clasped his hands together to make an oval shape around his mouth to enhance his voice, no avail to summoning the fiend by name. “Beam where are you!” Denji called out again while looking in all directions, “Beam come the fuck out!” Denji was quickly frustrated, he planned a date with Reze earlier and this could drag on further if the shark-fiend was somewhere dead.

He groaned in annoyance while kicking his shoes off and planting his feet in the water, upon looking down he noticed a figure below.

“Beam?” His voice was low as he scooted himself off the pool walls and into the water, “Wait I can’t swim..” Denji began thrashing around in the water, his lungs were being engulfed by the chlorine combined water, “Such a lame way to go out..” His eyes slowly began to close until he was tossed out of water, immediately his body began its process of removing the liquid from inside as he was thrown into a fit of coughing and wheezing.

“Denji.. What are you doing here?” 

The voice belonged to Beam, Denji whipped his head towards the other. Was he seriously asking that?

“Ms. Makima was unable to contact you Shark-Fiend, what exactly are you doing here? You’re not attempting to go AWOL are you?” Aki was next to speak as he walked closer to the two, Denji studied Beam, he could notice several things.

One, the shark wasn’t his natural self, the energy he usually carries around was nowhere to be found at this moment.

Two, Beam was naked.

Okay so maybe not several things.

“Beam, where are your clothes?” Aki offered his jacket for the fiend as Beam took the offer but didn’t say a word.

“Let’s go.”

—------------

Beam was shaking slightly when brought in front of Makima, Denji and Aki were currently on the other side of the door waiting to be called back into the room.

Makima shifted slightly making the fiend flinch, almost as if she made a new discovery, a smile formed on her face, “What makes you scared in this moment Beam.” Her voice had a hint of amusement in it as Beam turnt up to face her.

“You.” He was quick to cover his mouth as a whimper escaped his lips, what was he possibly thinking, he knew something was wrong with Makima, the woman was one of the primordial fears.

Makima walked towards him as Beam stumbled back, “Please let me live! I just want to spend my time with Denji!” Beam cried out in an attempt to reason with the Devil, “I wasn’t going to ditch the committee! I just didn’t get the memo! I swear!” Beam put his arms in front of him as Makima pushed them aside, “Beam. What is it that you know about Denji?”

Beam went quiet, “Hm?” She put her hands onto his chest, while grabbing his own hands and placing it onto her chest- specifically where her heart was beating- “Did you discover love for Denji?” 

Beam made a noise that apparently Makima found amusing as she stood up, “I too love Chainsawman, I wonder what makes our love different.”

And that’s how Beam realized the moment right there, Makima adored Denji for the sole reason of what was connected to the boy, The Chainsaw Devil.

He on the other hand loved Denji for Denji, he wanted to spend his day holding the boy's hand, breathing in the same air as him, feeling the other’s warmth, being cared for.

Makima looked down at him with her eyes holding a gaze unlike any other he had seen so far.

 “If you fall in love with Denji, I’ll make you experience a death worse than any before Shark-Fiend."

Chapter Text

Beam was quiet now-of-days, after his talk with Makima he couldn’t really dare to try making any intrusive thoughts appear in his head, he didn’t bother Denji with his chants, never applauded the man when he killed the weak Devils, left immediately after every mission was done, and even when Denji made his way to the diner the shark fiend just found a table and kept his body in a state of blank.

“Your friend seems like the talkative type.” Reze- Denji’s crush and hopefully soon to be girlfriend- pointed towards the fiend who was looking outside the huge glass window, “He’s just an idiot.” Denji moved his hand closer to Reze as she grasped it, “Your hands are very soft,” the boy blurted out as a blush came to his face. She giggled while cupping his cheek with her hand, “Your skin is also smooth Denji,”

Beam tilted his head at the sound of Denji’s name being said, he secretly wished he hadn't, the sight of Reze and his Master kissing almost made the fiend throw up, so with a sigh he pushed himself away from the table and walked into the bathroom. Ever since the discovery of emotions he hasn’t been feeling the same, and it’s only been two days since these events began,he wonders how humans deal with these things every second. Before he could open the stall door a hand stopped him, the scent hitting him before he could see who it was.

“Wuts the matter with you?” Denji’s voice wasn’t concerned for the fiends well-being, he could tell, so what made him bother coming towards Beam?

Upon turning around Denji’s eyes softened as he watched the fiend's lip quivering, “Are you crying?” 

What a dumb thing to say.

Beam stopped his lip as he yanked his arm away from Denji, “Sharks have to use the bathroom too y’know.” Beam wish he could control the little anger that seeped out of his words, “Jeez fuck you too man, go swim in that toliet water.” Denji turnt around as he walked out the bathroom, while closing the door, he could’ve sworn he heard a whine coming from the shark.

Beam stared at the restroom door his friend left as he tried containing his whimpers, he opened an empty stall while slamming and locking the door he slumped against the wall, faint sniffles and whines escaping his mouth, this emotion was sorrow, he never really felt it before due to always being the energetic fiend he is, but now it was making his brain hurt and go crazy.

Every other fiend wasn’t like him, they either were greedy, fearful or prideful, he only experienced pride before all these other emotions came into play. “Why am I becoming like this!” Beam began to slam his head into the door of the stall, “Fuck!” He screamed as his body began to squirm, his head still being forcefully smashed against the door, “Fuck you!” He cried out again as a headache began to develop, “Fuck!” His screams went unnoticed by anybody outside the restroom due to the sudden Devil attack outside the cafe.

It was only when a kick to the face sent him flying into the toilet bowl did he wake up.

He groaned while turning his head to see the intruder, “Stupid Shark-Fiend! Bathrooms are meant for relieving yourself! Not sleeping!” Power exclaimed with a  laugh while pointing at the fiend on the ground, Beam’s eyes slid to the man next to her, Aki, he held his usual expression, “Beam, let’s talk.” Aki held his hand out for the shark- Beam hesitantly grasped it as the former pulled him onto his feet.

In an alleyway, Beam was sitting on the ground as Aki stood beside him smoking a cigar.

“Explain your recent behavior.”

Beam froze for a second, “I.. I can’t say!” He covered his head with his arms, “I can’t! I can’t! She’ll kill me!”

Aki looked down at the Devil with his eyes slightly widened, “She? Who?” Aki lowered his body so he was properly able to view the Devil’s face, “Who. Beam.” He grabbed the Devil by the face and jerked him forward so his mouth and snout were in his direction. Beam wishes he could’ve snatched his face away from the boy, but sadly that’ll make his situation worse, “Makima..” The shark wished he could look away.

Aki let go of his face while standing up, hovering over the shark, “Ms. Makima said she’ll kill you for liking Denji?”

Beam could tell the other wasn’t buying any of his words, “I-it’s true! I wouldn’t lie! I wouldn’t!”

Aki raised his hands up to silence to shark, he then inhales his cigar, “I don’t really understand the reason behind this, nor do I think I want to know, there’s something about Ms. Makima and her fascination with Denji, or rather, Chainsawman.” Aki looks back down at Beam as the other one continues his dazing at the wall ahead of them, “It’s too short of a world we live in, if your love for Denji is true then maybe dying wouldn’t be as bad as it seems, you’ve died before right? You’ll meet Chainsaw in Hell someday anyways.”

Beam shivered at the thought of going to hell again, he didn’t like the place at all, all Devils go there after dying in the mortal world.

“Love’s going to get me killed.”

—----

Denji and Beam were back on patrolling but in a different part of the city, Beam wasn’t as quiet as he used to be, he continued doing his applauds for his admirer.

However, Denji got hungry quickly and decided to buy some snacks for the two.

They found a rooftop to watch the overview of the city while eating, Beam settled for some sushi, sitting below the small protruding portion of the wall, while Denji sat above the wall while stuffing his face with a sandwich.

“Denji… Who’s the girl.. You always visit?” The shark was hesitant to ask, he knew how easily bothered the other gets by his presence, but he had to know what he saw in her that Denji doesn’t see in him.

Denji shifted slightly, “Reze..? The hot chick in the cafe? Her?”

“Do you like her!?” Beam was quick to blurt it out, his hands were shaking from nerves, just for once he would like it if Denji didn't hurt his feelings.

“Yeah.”

Beam felt his heart sink, it felt as if the organ actually moved downwards, “W-why!” Beam could feel the other feeling from before, the one of sorrow, he couldn’t help the way his body reacts from it, constantly having battles with himself.

Denji rotated his body so it could now be in view of the shark, “Are you crying?” Denji rolled down to the gravel floor as he scooted next to Beam, “Do you like Reze too!? I’m not sharing man!” 

Another feeling, frustration, Beam never felt it before really, no matter what. However with Denji’s incapability to pick up on social cues along with his life being on the line, he couldn’t hold back anymore, “No Denji! I love you!” He screamed, something he never thought of doing unless it was in excitement.

Denji’s face was blank.

“What.”

Beam was frozen for a second, Denji wasn’t gay, Denji never was into guys, whenever he saw two males holding hands or kissing he would bash the idea loudly, he was however into lesbian things. Beam was done for, if Denji were to bring this up to Makima then he would definitely die, she’ll send him back to hell.

“Are you.. A faggot Beam?”

Denji’s word felt like they were piercing through Beam’s brain, stabbing a part that led to an itch, the world around him felt unreal for a moment, Denji’s blank stare slowly turning to disgust, the way Denji’s fist were balled up, and how the beautiful city behind them was in contrast to what they were going through. Beam had to save himself.

“N-no! I meant.. I love Master Denji!” Beam’s brain was quick in this scenario, he stood up with a nervous smile, “Y-yeah! I am in love with you Denji! That means I want you to be happy! I’ll do anything to grant you- your date with Reze!” Beam could feel his body going into overdrive, trying to find the right words all in a moment was hard.

Denji seems to accept it as his disgusted face turns into a grin, “Why didn’t you say that buddy?” Denji stood up while tossing his hands around Beam’s shoulder, “Let’s go shopping! I already made an arrangement to go somewhere with her tomorrow!”

If Beam was smarter, he would’ve declined to go somewhere and hopefully rot away, but he didn’t want to raise suspicion.

The two walked around to shopping outlets, Denji trying on clothes while Beam rates him, although the shark mostly got his taste from humans in his previous lifetime, which was recent, Denji’s outfits mostly consisted of messy colors put together, however, Beam was able to put together a simple one, a baggy grey sweater with a brown shirt on top, grey joggers and a newer pair of red shoes, Beam thought the outfit brought out Denji’s orange hair and eyes, he wanted to say it so badly but he couldn’t, so he just smiled at his friend, and that’s all he did for the entire night.

As the two parted ways, it took a while for Beam to find a secure spot to let his emotions out, he was far, quite far.

He was at the beach actually.

It was the only place he could feel, himself, with the sound of the tides crashing along each other, the casual humming of car engines from the distance, and the conversations from those who attended the beach this late.

He sat at the shore, the water attempting to pull him in with its weak tides.

He opened his mouth, holding it, deciding if he should openly express his feelings to whatever ears the ocean had. “I..” Tempted to begin, “I like the Chainsaw Devil.” His throat was croaked, “I like Denji, I love Denji.” It was almost as if he was admitting, which he technically is starting to do, “I love Denji..!” He said it a bit louder.

Pushing himself forward into the water, allowing for his devil ability to submerge him, his body holds no binds to the water’s pressure, to be free from pressure is amazing, if only he could do so above water.

He floats to the top, chest and face exposed to the night’s air, “I love Denji!” He screams it out, a happier tone than from before, “Denji! I love you!” He grins to himself while letting out his sharky laugh. 

His laugh dies down as he runs a hand through his wet hair, a sigh escaping his lips.

“This pride is going to kill me.”

Chapter Text

“No Denji! I love you!”

“Let’s do it.”

“Your first indirect kiss… Is the flavor of Chupa-Chups.”

“Your skin is also smooth Denji.”

“Don’t open the door Denji.”

The pounding on the door awoke him from his daze, “Denji! You’ve been in there for an hour!” Aki’s voice was muffled by the door but Denji got the message pretty clear, the boy closed out the tabs of girls naked as he wiped the leftover cum that dripped messily from his dick. As he got it while flushing, he shifted towards the sink that held a wall-mirror above it, seeing himself after committing the act he just did made guilt form inside his stomach.

As he walked outside the bathroom he was met with an angry looking Aki, “Why did it take you so long?” His blue eyes glaring into Denji’s orange, “I fell asleep.” Was all the halfling could say as he went past him, “I’m going out.”

Aki shook his head, “Be back before 1.”

He didn’t receive a verbal answer but rather a wave along with the door to their apartment closing.

—---

The streets were busy today and surprisingly there weren’t any Devils currently attacking, for once Denji felt like today might be a good day.

“No Denji! I love you!”

Beam’s voice kept screaming in his head. Last night was strange, but he couldn’t overlook the fiend’s frightened look when they sat above the city. For a second, Beam seemed as if he was actually hurt from Denji’s reaction, but that’s crazy.

Unless… 

Beam is a faggot.

The shark never seemed interested in the women Denji used to point at, only saying things like, “As long as you’re happy Master Chainsaw!”, “Is that your type Lord Denji?”, or “You have great taste Master Denji!” Wouldn’t a normal guy say that he also wants to tap that? At least the guy’s he sees on the streets or series he watches. They would always point towards the women, make pickup lines he thought were cool, show off how rich or manly they are, and if that guy had a friend then the friend would ask the lady if she has a best friend.

But Beam never did that, not once did the fiend show any signs of sexual attraction towards anybody.

“Are you... a faggot Beam?”

Denji grimaced at the word choice he used, but was he not in the right? Being gay was not normal, it was beyond normal. Two men shouldn’t hold hands unless they’re helping each other, they shouldn’t be kissing, they shouldn’t be in bed together nor should they have sex. Maybe it’s because Beam was a Devil, that’s the only logical reason. In a world like this, it’s best to live and breed, that’s simply the way of life. Two guys can’t breed, so why should they live in this world?

“I love you Denji!”

Beam was likeable to an extent, Denji loved whenever he received praise because it made him feel like he was a kid again, being rewarded for doing things such as making a drawing, or handing his Grandpa something, he just wanted to feel appreciated. Beam made sure of that whenever the pair hunted Devils, and that night Denji did feel a bit of pain at seeing the fiend’s face after his own confession for his love towards Reze, “Why would Beam like me?” Denji murmured while he continued to walk mindlessly.

Makima admitted to liking Denji before, but is it the same love that Beam has for him?

Reze also seems to love Denji, these past few days they’ve been doing things normal couples would do, she even seemed to enjoy the bouquet of flowers he brought her recently.

But is it the same amount of love Beam seems to have?

With Reze, she would smile wholeheartedly, it was almost blinding, the way her words flowed so easily, and she wasn’t disgusted by any of his flaws, whenever he ate like a pig she would just giggle and join him. The way her hands caress his own would send butterflies to his stomach, it’ll make his head spin, Reze would kiss him while she holds onto him tightly, almost as if she doesn’t want to let go.

Makima was more sly with her implications of love, giving him more of a reward system rather than being a normal happy couple. She’ll make love seem as if it was a one-way thing, making the other person- him in this case- feel flustered, depending on her for safety, he wanted to do that. 

Both females were hot, Reze had a cute figure, beautiful eyes and she smelled lovely all the time, her ass was the right size along with her breast, he would squeeze them if she let him. Makima on the other hand, was perfect, her soft voice matched her personality, almost giving the sense of innocence, but he knew she was probably a freak, her breasts were perfect, the way her waist curved to shape her figure was perfect, even her fat ass was perfect. Yet he couldn’t do anything with this information.

However, Beam doesn’t fit in any of these categories.

Beam was loud, annoying, weird, and had no true sense of what love could be.

But he loves Denji.

For a guy Beam was caring, whenever Denji seemed to trip he would always catch the boy, if Denji needed better access to something then he would be there waiting for Denji’s command. He never seemed to sweat either, and although he uses his mouth to attack, whenever Denji saw the boy smiling, he never saw any blood, yellow stains or even food. Beam was hyperactive, he reminded Denji of Power before Aki tamed her, the boy would always check on Denji’s wellbeing too.

Beam’s body was incredibly built, since he is always shirtless, Denji had a good image of the boy in his head. Beam’s back was wide, his arms had muscle on them, they weren’t huge or shredded but a decent size. His chest was huge, he had pink perky nipples that constantly seemed erected, below his pecs lies the abs that stood out incredibly, along with toned legs…

Beam also had a fat ass.

“What!”

A couple of bystanders jumped at the sudden noise from Denji as he quickly looked around and apologized.

Fat ass? Did Denji actually say that in his head? Sure whenever he glanced at the fiend he would see it, they were tight on his shorts, the tight jeans that completed his figure perfectly, high thighs were also decently sized too..

“What the fuck..” 

Denji stood outside of the Cafe as he had his hands resting on his head, “I can’t be..”

“Hey Denji!” Reze's voice took over the boy’s consciousness as she guided him by the hand to wherever.

—----

Tongues lapped at each other as Denji's hands were full of Reze’s breasts, he fondled them through her bra as she moaned his name.

They decided to break into a school nearby since none of them technically went to a public school, it was nighttime, nobody was in the building, not even a security guard, the rain outside had set the mood for them, it began with Reze touching Denji’s hand while guiding it to her pussy.

She was sprawled out on the teachers desk as he hovered over her, her back arched, legs lifted into the air alongside his body. Her shirt was unbuttoned, panties thrown off, skirt lifted so that her precious lower half was exposed and pressed against his.

Denji was in front of her, dick throbbing within his briefs that were pressed against her womanhood. His shirt was thrown off, leaving him with the grey sweater Beam picked out, his hands traveled her body like it was a map, tracing everything about it.

She pulled back from the kiss with a lustful smile on her face.

“Put it in Denji.”

His mind had gone blank again.

“I love you Denji!” His face was blushing, at least the human half that can, his hair swayed with the gentle breeze that emerged, his lips were pink with a little grain of rice hanging from them.

“Your first indirect kiss.” She held the Chupa-Chup in his hands, yellow eyes with motives dazing into his own, Makima was beautiful compared to the scenery behind her, only she stood out.

“Let’s do it.” Himeno’s lustful, drunk face, hovered above his, the moon light made her skin glow, he still remembers the puke she slid into his mouth

“Denji…  What are you doing here?” Unlike every other moment that passed in his head, the final one of Beam was from the day he found the fiend in the pool, so why was he able to hear him so vividly, see him so perfectly, standing at the end of the teachers desk, watching with no eyes, “Denji… Do you like her?”

“Yes.”

Denji's answer was out loud, he didn’t mean to open his mouth, but it seems as if Reze thought he was referring to whatever she said.

“Let’s go to the rooftops then.”

He didn’t know what she asked when they made their way to the rooftop, apparently it stopped raining though.

“The fireworks should begin soon, maybe it’ll be nice to get a kiss once they begin.” Reze’s face still had a blush on it, Denji just stared at her.

She kissed his cheek, “I truly do love you Denji, more than you know.” She says it in a whisper close to his ear.

He holds onto her waist to keep her still, almost as if she was fragile.

“Do you like her?”

Beam’s words echoed in his head again.

“I love you too.”

His body had a different response however, he began to lean in as she did the same. Their lips connecting as the fireworks in the background colored the sky along with creating ear-damaging explosions.

“Denji.. Why are you here?”

For once he would like for Himeno to stay dead, for once he would like for Makima to treat him how he wants to treat her, for once he would like for Beam to explain what love he has for him. Moments such as these, where somebody he loves isn’t seeking some reward, isn’t treating him like some God, doesn’t offer him things he can’t imagine. Reze can do that, she wasn’t after anything…

Right..?

So why did when he pulled away, he saw the tip of his tongue hanging from her mouth, the blush on her face never fading away as the beautiful fireworks that exploded a series of colors in the sky radiate off her face.

“Denji… Why did I love you.”

It was a scramble of words that made him question his proposal for coming here.

Reze did want something, and it wasn’t anything good.

As she pulled the pin hanging from her neck, Denji was taken away by somebody.

His head couldn’t process much that night, but watching Beam leap from the floor, reaching out towards him, grabbing him by his waist, and screaming out his name did make him wish he could ask why Beam loved him.

In the moment they were suspended in the air after falling from the school roof, Denji could see the emotions that spread across Beam’s face.

“I love you too.”

—---

The Bomb Devil.

Beam knew she had a putrid scent to her, perhaps that’s why he never approached her or she never got too close to him, and of course that would explain how Denji was delusional to it all, he didn’t have as good of a scent as Beam- Beam wouldn’t blame him though, he was glad he could be there for Denji, especially now as the two boys enjoy a cone of ice cream while watching the busy streets from above.

The fiend didn’t say much ever since the events that happened with Reze, he also knew that Makima may have done something to her, but that’s for him to know.

The shark was just doing what he thought was best, which was using his paycheck to take Denji to places that could cheer him up. He couldn’t tell if it was working, but Denji would always make the call first, pointing at places with his signature look of boredom. Maybe Beam was the fool for falling for his trap of guilt tripping, maybe his love for Denji grew more than he anticipated.

“Were you there the entire time?”

Beam faced Denji, the boy wasn’t looking at him however, only looking at the cone of ice cream in his hands, the vanilla slowly running down its cone.

Beam didn’t want to answer, he was there that night, on the other side of the wall that was hollow on the inside, he heard everything they said, even Denji’s confession. Why he put himself through that is a question he’ll never find an answer to.

Denji slowly moved his head so that it was now facing Beam.

“What is it that you love about me, Beam?”

Beam snapped his head away to stop looking at Denji, the boy’s expression wasn’t one he had seen before, it was soft and vulnerable, his hand clasped over his mouth, biting down onto his lips. Although he could give Denji more than words, he couldn’t piece anything together right now, this was his moment to show Denji exactly what the sensations he’s been harvesting lately is.

“Denji..” Beam stopped himself, slowly rotating his body back towards the boy, “Denji, I’ve been having… Weird thoughts..” Beam bit his lip again, “I want to be there for you, hold you, depend on you..” He exhales while trying to gather his words.

“I felt… Frustrated, hurt, antagonized!” Beam's voice raised at the last word as he clenched the pavement curb beneath him, “When I see you, I wish that you for once would see me, you don’t see Beam!” His head was hurting, if he had eyes he would most likely be crying right now, “You see Shark-fiend.. Another Devil.. I don’t see that for you, Beam see’s… Denji.” His breath was shaky as he placed his hand on top of Denji’s while gazing into his eyes.

Denji mouth was slightly open, along with his eyes, he was in shock, “I don’t want to die again, I love feeling these things for you, even if I were to die many times now, I’ll keep sniffing out for Denji, not Chainsaw, even if I am erased from the Hell and Earth, I’ll comeback searching for Denji. Even if Denji doesn’t exist anymore, Beam will remember Denji.” The fiend cuffed the halfling hand as tears began to develop in Denji’s eyes, “W-why!”

Denji ripped his hand away while standing up, anger being placed on his face, “Why do you love me! What’s so special about me!” 

Beam shot up as he wrapped his arms around Denji’s waist, pulling him in, “Denji’s special because Denji sees life for what it is, not having fear of death, pure to the world of Devils, Denji is special because he was born special.”

Beam pulled away so that he was facing Denji.

He leaned towards Denji’s face as their lips connected, the taste of vanilla meeting strawberry.

Beam kept Denji close, holding his body tightly as if to not let the other boy go. Denji’s body was also warm, and since Beam was always cold he felt as though it was similar to being in a cold environment with only a blanket to get warmth from. The halfling didn’t budge, not even an attempt to punch Beam away, in fact, he tugged for the other boy to come closer, almost as if they were never going to see each other again.

The kiss was different from all his other ones, it wasn’t gross like Himeno’s, not indirect like Makima, or even metallic like Reze. When Beam kissed, it was flavorful, it gave him a sensation that made his brain go into shock, the boy's soft pink lips pressed against his own was comforting. He could never forget a day like this kiss.

 As the two began to part, slowly there was a trail of saliva that followed, Beam resisted the urge to pull the other boy in for more but he wanted Denji to feel as if he was the boss. The kiss was passionate, he could see Denji’s lips being slightly red along with the blush that was on the boy’s face.

“Denji likes?”

Beam was beautiful in Denji’s eyes, the boy's smile went from ear to ear, it was a cute innocent one, and although the shark didn’t have eyes, they would most likely shine from joy.

“Beam..

.. I love you.”

Chapter Text

Yellow-brown eyes were fixated on a certain object protruding out of the ground, a fin began erecting from the ground as a head and chest followed along. 

Beam’s joyous smile met his lover. The other boy shined a smile of his own as he pulled the shark towards him from the ground, “Denji! Denji!” Beam cheered as Denji gave him a peck on the lips, “Another day of patrollin’ with you,” Denji kissed the boy’s cheek as the shark let out a giggle of joy, “I also heard we’ll be goin’ on a vaca soon,” Denji purred into the fiend’s neck as he pulled him into an alleyway, “Denji,” Beam voice was shaky as he felt his partner get handsy, “I wanna do it somewhere romantic with you..” The halfling groaned as he pressed his hard-on against his lover, making him huff out air while grinding his hips to gain more pleasure, “But watchin’ you in these shorts keep makin’ me unstable!” Denji groped the jean-shorts of the shark as he toyed around with the cheeks.

Beam's head felt light as he was pushed against a wall and legs were lifted up.

He placed his hands on Denji’s shoulders as he felt the hot bulge being pressed against his own, “D-denji! Please!” The shark pleaded as lips crashed into his own.

It was hot, hot to the point he couldn’t breathe correctly, when Denji pulled away his face was filled with lust.

Denji placed Beam down as the two were out of breath, “D-denji? Why pull away?” Beam felt as if he did something wrong as he tried walking towards him.

Denji put his hand on his knees as he tried catching his breath, only holding his hand out towards the shark to grab onto.

“I wanna have sex with you.”

Beam's face turned red instantly as he began to stutter. His head was scrambled as he tried finding words. “L-le-” He paused, his head turning left and right frantically. Someone. No. Something was watching them. 

The fiend pushed Denji off as he tried recovering himself, “Beam?” Denji tried touching the shark but his hand was slapped away. Beam’s face held a frightened expression, “Let’s patrol. No Devil here.” The shark sunk back into the ground as he swam away to continue their route.

“Beam what the hell!” The boy yelled as he chased after the fin that protruded from the ground. The fiend lifted his head up, trying to give off a calm and happy facial feature. “Later.” He simply stated while going back into the ground.

Denji was beyond confused now, he knew that the shark wanted to be interactive with him just as much as he did, so why was he being this difficult all of a sudden.

He let his mind wander while walking through the crowd of people on the busy sidewalks.

He remembered how the shark was frantically checking his surroundings, almost as if he was suddenly caught in the act. Was he embarrassed by me? Do Fiends even feel embarrassment? Power entered his head as he tried figuring out a time she ever felt that way. Maybe she’s a bad example. 

Beam and Power were different, in fact Beam was different from every other person he’s met. The shark was the first one to treat him with actual affection. Even after the many times Denji was rude to him. 

Beam reappeared from the ground in front of Denji as his lips were quivering. The other boy stared in slight shock, “Beam,” he reached his hand out towards him as Beam latched onto Denji for a hug. “I’m sorry!” The shark's voice was muffled due to being pressed against Denji’s neck area. “I’m scared. Something was watching us! A devil! I could sense it!” Beam grip on Denji was hurting but he wasn’t as concerned, his only concern was the anxious fiend holding him.

Denji lifted Beam’s head and planted a kiss on his lips, “It’s ok, I’ll defeat any Devil that tries to harm you, you’re special to me.” 

Beam kissed Denji harder this time, pushing his tongue inside the other’s mouth, trying to replace his fear with love.

When the sun began to set and the two patrol was over they immediately went to Aki’s apartment. 

As Denji stood outside while Beam fin pointed out the ground, the shark came up. “Nobody’s inside.” He wasn’t looking at Denji, he was blushing from saying just that sentence.

“Nobody’s home.. Huh..” 

He walks inside while kicking his shoes off as he makes his way in his room, sitting on his bed. “Cmon Beam,” Denji’s voice was full of lust, the shark couldn’t bother resisting as he came out the ground, only showing his upper half, but Denji noticed that the part where the Shark’s shorts would usually be weren’t there.

“All the way.” 

“Is that an order Master Denji?” 

“Correct.”

Beam’s heart was beating rapidly as more of himself came out the wooden floor, Denji eyed him hungrily as he could feel a rise in his tight pants.

Beam was sitting in front of him, his two dicks fully erect and hard. His head was tilted to the floor, almost as if he was avoiding Denji’s gaze.

“M-master.” 

Denji knelt down in front of the other boy as he lifted his head up to kiss him, their lips coming together for a soft kiss. 

Denji went behind Beam as he rubbed his hands over his back muscles. The shark was toned, Denji knew that. But feeling him like this was different, Beam’s fairly tanned skin, the shivers he could feel scattered across the shark’s body as he massaged his back.

His hands went past his shoulder blades and armpits. Beam was hairless underneath there, he didn’t even smell horrible, in fact he smelled similar to a bubble bath. Did he disappear to bathe earlier? Denji’s hands made it to Beam’s chest. A low whimper escaped his throat as he let out a breath of air.

He rubbed his chest, gripping it tightly and letting it go, holding and making circles from the muscle. He could feel Beam’s heartbeat grow rapidly. His fingers traced over the pink nipples as the Shark made a strangled noise, the view from behind was amazing to Denji. Beam’s back was straightening constantly as the shark squirmed from the touch of his tender nipples.

“Mas-ter!” 

“D-denji!”

“Sir pl-please!”

The more Denji continuously pinched and slid his fingers over the pink flesh, the more Beam would choke on his words.

Denji kept one hand on the Beam’s nipple while the other went lower, going over his abdomen that had the muscles accompanying it, he reached a bushier area.

Denji leaned in closer to the boy’s ear, “Somebody’s been letting his jungle grow.” Beam’s head felt light as he could feel the other boy’s hot breath against his ears. He moaned suddenly at the harsh bite that Denji left on his ear. 

Denji bit again on his neck, earning more whimpers from the shark as he continued to explore the shark’s body, never going lower than his hairs. Beam was growing tense as he wanted Denji to soothe his hardening.

“Master,” Beam began as he turned around, tackling the boy into a kiss, his tongue slobbering all over Denji’s mouth and face. He sat on the boy’s lap while panting, “Please let me..” Beam could feel it pressing against his ass as he let out a moan, rubbing his ass against the bulge that hid in Denji’s pants making the other boy shoot his head back while moaning.

Denji grabbed the fiend’s butt as he spread it while pressing his bulge against him. He began grinding against his ass while calling out the other’s boy name as Beam could only breathe out what he would assume is ‘yes’.

Denji moved his hands to Beam’s hips and he pulled the boy towards him as he hugged him and continued to dry hump his lower half. Beam wrapped his arms around Denji’s head as he let his moans rant out of his mouth, the heat from the two making it almost insufferable to continue on with each thrust.

Denji pushed the boy away slightly as he tried catching his ragged breath, he realized the main issue. “Beam, strip me.” Denji husk voice demanded as the shark with his open mouth panting nodded with a swallow of thick saliva.

He moved his hands to Denji’s lower shirt as he began unbuttoning, his hands shaking from Denji’s teasing of his two dicks with his feet. “You’re leaking.” He heard his master chuckle as Beam tried focusing on his assignment as he whimpered quietly.

Finally making his way to the top collar he took off his master’s white shirt and tossed it aside. Beam put his hand on Denji’s chest as he felt along his body. Denji wasn’t as muscular as he was, his body was more lean but Beam never cared for Denji’s body until now, he wanted nothing more but for the boy to wrap his arms around him and explore him. His hands trailed down to Denji’s pants, the not-so-obvious bulge moving underneath the fabric. 

He licked his dry lips as he wasted no time in undoing the zipper while pulling Denji’s pants down.

Beam loved Denji’s legs, whenever he was in the ground he would go from behind and watch the boy walk. Denji's ass would shift so majestically while walking, it always kept Beam hard as they patrolled. He pulled the black slacks off as he grabbed Denji's foot that was fortunately moved away from the boy’s aching cock closer to his face. 

“Wait B-!” 

Beam licked the foot while Denji made a face of disgust and tried releasing it from shark’s grip, but Beam was obsessed, Denji’s feet were salty but not in a bad way, they weren’t as dirty as the many other times Beam seen his master’s feet due to the two of them only walking in their shoes today. His tongue danced across Denji’s toes as the boy continued to struggle, “Beam! They’re gross!” He called out to his partner. Beam let go of the foot as he grabbed Denji’s thigh and reeled him in closer making Denji yelp as he was dragged across the wooden floor.

The shark was now looking down at the orange-haired boy who was a blushing mess- possibly due to having his feet inside of his mouth- Beam leaned down as he kissed Denji’s cheek, “You can kiss me Beam. I got kicked by a guy in the face before, I had a foot in my mouth once.” Denji chuckled as he could imagine Beam rolling his eyes before he felt lips against his own.

The two stayed in that position for a while, their kiss deepening as they could feel the air from the nostril exhale heavily with each passionate kiss. They both internally enjoyed kissing each other, exploring each other's mouths and letting their tongues dance against each other, sucking on the part as if trying to pull it back in.

Beam pulled away as he grabbed Denji’s final piece of cloth from his body- his underwear- he ripped it off as Denji screamed, “Beam! That’s my favorite pair!” 

The shark laughed as his master punched his shoulder, “You owe me.” Denji glared at him while poking Beam’s bouncy chest, “Yes master!” Beam happily replied as he lifted Denji off the wooden floor that they’ve rested on for so long.

“Bed time?” 

“Bed time.”

Denji got off the floor and sat down on the bed, patting the empty spot next to him for Beam.

As the shark sat next to the chainsaw man they didn’t move yet.

“Master.”

“Yea?”

“I.. Never had sex.”

“Oh.”

“Sorry.”

“Me neither. Let me just lead you, I have seen tons of porn.”

Beam was positioned on the bed with his ass pointed upwards while his head lay against Denji’s soft scent covered pillow. Denji was behind the boy trying to apply a condom that he stole from a store, the boy grew frustrated easily cause it felt like his dick was being strangled, he tossed it aside with a shrug as he grabbed the purple lube bottle. “Beamer, I’m not exactly sure if you can get pregnant from sex.” Beam blushed at the nickname as he turned around to Denji, “I wouldn’t mind.”

Denji smacked the shark's ass softly, “That’s not a good thing! What if you can’t go on missions with me!”

Beam gasped while straightening up, “You’re right! Nooo! Don’t pregnate me master!” Beam begged while Denji leaned him back down, “No. I’m cumming inside of you.” 

“What!”

Beam couldn’t get another word out as he felt a cold wet finger slide inside of him, “M-master what are you doing!?” He bit into the pillow while groaning as he could feel the finger moving around in him.

“This is what they do before sex all the time, does it feel good?” 

Beam back arched more as he melted into the touch while letting out a whine.

“Then yes.”

Denji slid another finger in as he used his other hand to play with Beam’s balls that hung and bounced wildly due to the boy trying to grind against Denji’s fingers.

Denji dick was springing at the thought of going inside of Beam’s pink hole. Even while he sits here fingering the boy, Beam’s ass was thick with the shorts off, the boy even had a farmer tan due to wearing the garments so much. The way his hole gave the impression of sucking Denji’s finger back inside left the boy wanting it to be replaced with his dick immediately, but he didn’t want to hurt the inexperienced shark.

Denji stopped playing with Beam’s balls as he rubbed the shark’s ass, “Good shit I love your ass Beam!” Denji admitted happily as he took his fingers out, he glared down at his happy dick that throbbed, precum emitting from the tip, It’s not enough! He felt his mouth go dry. Wait.. My mouth.

Denji put his arms underneath Beam’s thighs as he pulled the boy’s ass to his face, opening wide he engulfed the hole with his lips as he felt the heat emitted from the shark against his face. His ears were ringing but he could make out Beam’s cry of joy as the shark’s toes curled and uncurled.

Denji tongue danced against the pink hole as his own saliva was now replacing the lube that he applied, although the lube taste was gross, Denji had worse. However, knowing that it was Beam’s ass he’s eating out was the better part.

He moved his tongue to go inside of the boy’s hole as he melted into feeling the inside heat, his tongue felt like an adventure going into uncharted territory, and he loved every moment of it.

Beam couldn’t make out a single word from his mouth. His head was spinning, he was so hot. Too hot.

Denji pulled away as he kissed Beam’s hole and set the boy's lower half to sink into the bed.

The chainsaw man crawled on top of the shark as he laid on his back, his dick hotdogged between the boy’s cheek. He grabbed Beam’s hand and intertwined his fingers with his while planting a kiss on the shark’s head. “Get ready Beam.” Denji's voice was low as Beam whispered an ‘ok’.

He lifted his lower half- too tired to untangle his hand from Beam- as he spent a few seconds positioning his dick to poke the hole of the shark. “It might hurt for a little bit, please understand Beam. Just let me into you.” Denji pleaded as he could imagine the shark closing his eyes, but he could only see the shark quivering lips from the side of his face.

When Denji lowered his bottom half he watched the shark bite into his bottom lip as a cry escaped his lips. He knew it’ll hurt, he wanted to make it less painful for the shark but it was almost like a primal instinct to just fully enter Beam.

Beam was on the verge of screaming as he could feel Denji’s length enter his hole, stretching it out, “Master!” He couldn’t help it, he gripped the bedsheets and Denji’s hand as he turned his head into the pillow to bite onto it. Denji’s dick was bigger than he expected. Was sex with Denji always going to be like this? Beam exhaled a breath he didn’t know he was holding in as he could feel Denji no longer entering him. His master was fully within him.

Denji was planting kisses along Beam's face as he whispered soothing words to the shark who could only nod and rub his hair against Denji.

“It might hurt again Beami, I’m sorry.” Denji's voice softened as he wrapped his hands around Beam, bringing himself and the shark up, “I love you Beam, ok? I love you so much.”

The shark would be tearing up right now if he had eyes but he could only whimper while putting his arms around the arms of Denji that clung to his chest, he separated his legs slightly as Denji began to slowly thrust inside of him.

The feeling of it was weird and foreign to Beam but it was Denji. He shot up as a sudden pain shot through him- earning a series of apologies from Denji as the boy readjusted and continued his action.

This was heaven to Denji. Beam’s warm insides, his tight walls wrapping around his virgin cock, he could feel the wetness from his earlier stunt as excitement filled his heart, he tightened his grip on Beam as he began to move faster. He rested his head against Beam’s back as the boy was moaning even more than before, trying to call out Denji’s name which only made the boy move faster.

Beam shot up again and full off of Denji’s dick as he whined in pain, his bottom lip turning red due to how hard he’s been biting it, “Master, make it feel better! Please!” Beam cried as he rubbed his ass, Denji sympathized with his partner, the sight of seeing him badly hurt from something that should be enjoyable was hurting his heart, but his dick wouldn’t let Beam off the hook so easily.

An idea came in his head as he picked up the shark and sat him on his lap. Beam was facing the chainsaw man as he was blushing, “I-is this a good position?” Beam wrapped his hands around Denji’s neck, pulling himself in to rest his body against the boy. “Yeah, the best part is soon to come.

Denji slid his dick back into Beam as the shark straightened up, Denji eyes were locked with where Beam’s would’ve been if he had the. He was holding onto the shark’s waist while having him bobbing in his lap, Beam’s lips were parted as he moaned with the deep thrust Denji gave him.

“Master, when best part?” Beam asked in between whines as the other boy smiled, “This!” Denji closed the distance between their lips as Beam immediately reciprocated the movement, wrapping fully around Denji almost like he'd fly away if he let go.

Denji held onto the shark’s waist as Beam legs wrapped around Denji. The boy stood up while holding his partner as he began thrusting faster, forcing Beam to moan into the kiss that Denji desperately tried holding.

Beam’s two dicks were flopping and swinging wildly as the boy’s body moved with each thrust his lover gave him.

The two boy’s moved back onto the bed as Denji laid fully down while Beam rode his cock,his back arched back, hands behind him while his feet were planted on Denji’s side, he was moving his body against Denji’s dick while the boy watched, playing with the two dicks that continued to move on their own until gripped by Denji.

They continued to switch between positions before settling to cum to each other while in Denji’s lap. 

Beam was a mess, he was whining and moaning loudly while Denji grunts and groans and occasionally smacks his ass. He pulled the chainsaw man into a kiss as he could feel his two dicks shoot rounds of cum all over the two stomachs. Denji at this same time had released his load inside of his lover, the two both holding onto each other as shivers from cumming tormented them.

Tucked beneath a fresh blanket that Denji had under his bed, he laid behind Beam who’s been rubbing the hand that Denji wrapped around his chest. “How do you feel?” The chainsaw whispered from behind the shark who didn’t move.

“Honored. Glad to be in bed with Denji.” Beam chuckled softly while kissing Denji’s hand.

“Well we can do it more, you know.. I’m pretty.. Active.” 

“Beam knows.”

The two laughed at the inappropriate joke.

“I love you Beam.”

“I love you too Denji.”
