The Blood Devil Learns What Powers Erections

It’s rare for a story like this to start in post nut clarity. But then, with how Denji’s brain was buzzing in blissful static, he’d be fine with rewinding the story a few hours for you. Or maybe he’d just eat the cold open devil, who knows.

He stretched out on his bed. What was once a shitty average pile of sheets and a mattress was now a literal swamp of sweat and semen. His virginity loss had been an incredible feeling, but then it had just stretched out hour after hour into the best thing he’d ever experienced. Cock? Spent. Limbs? Exhausted. Happiness? Peaked. Maybe he looked, felt, and smelt like a wrung out dishrag, but who could care when life was this good?

Sure, maybe he was hoping it was Makima. Or a supermodel. Or that cute girl Reze from the coffee shop. Or even that girl that tried to kill him, Kobeni. But then, would they have been able to have lasted as long as the horned devil draped on his chest like a naked cat right now? He wasn’t sure. At the very least, Denji wasn’t expecting to be so compatible fucking for hours with Power of all girls.

It had all happened so fast. She found him masturbating, found the smell of his cum interesting, then demanded more ‘human meat juice’ until it escalated. Over and over again.

Perhaps this was the life that Pochita and he had always envisioned? So many hours of raw unrelenting sex with a cute (enough) girl, acting as insatiable as he was. It was clear that Power had both discovered and become addicted to sex after hour one, and Denji couldn’t help but be proud of how many times he’d made her squirt.

Now all that was left was to relax after a job well done. His floppy noodle stuck against his sticky thigh, it would surely rest there until the morning where he’d be awoken by his new girlfriend’s blowjob… like in the doujins…

“Again.”

Denji was just near drifting off when he had to slowly tear his eyes open again. Power had her chin on his chest, looking at him expectantly with her big yellow eyes.

Denji shut his eyes, “Nope. No again.”

“Again, human.” Power growled, her voice a seductive purr. She quickly grabbed his cock too hard, shaking it around so his head slapped against himself.

“Ow! Quit it!” he hissed, pushing her hand away with his thigh. “Guys don’t work that way!”

She wasn’t having it, diving down to grab his retreating prick, “More! More tasty meat juice, Denji! I know you have it!”

“It needs time!” Denji whined, “My dick is too sensitive! I can’t just fuck you forever!”

“Fuck me, Denji! Fuck my dirty slutty pussy ahegao juicy fuckhole-”

“I should never have taught you how to do dirty talk…” he mumbled over her delusional ramblings, “Look, it won’t get hard anymore, okay?” he said, helicoptering his dick around to prove his point. “Humans need breaks between sex.”

“It does look unimpressive compared to before…” Power frowned, giving Denji’s dick a flick that made him yelp. “Why won’t it obey me anymore?!”

“I ain’t got any blood down in my dick anymore,” he replied with a shrug.

This would be a sentence Denji would regret.

“...blood?” Power asked, raising an eyebrow while giving him a sultry smirk. His eyes went wide a little too late, right about when Power’s palm shunted forward to hover right above his dick. “I am the Blood Devil! I command Denji’s blood to make him hard! OBEY YOUR MASTER!”

“Wait, Power, what are you-AHHHHFUCK!”

It was the weirdest, most intense sensation he had ever felt. It was like every single drop of blood in his body suddenly received a direct order. He could feel it, a massive, internal tide shifting, rushing from his extremities, his head, his organs, all surging downwards in a concentrated targeted torrent. His face went pale. His vision swam. His fingers and toes went numb.

But his dick?

His dick was so fucking hard.

Denji just hung there for a second before his blood started moving around his body again. His erection didn’t falter even slightly, with precum positively gushing from his extended head, but it did take a minute before any other part of his body became active.

Maybe he’d have had a chance if Power didn’t let out a triumphant cackle. “Behold! Denji’s meat stick is once more ready to feed me delicious white juice! Ahhh~”

She didn't give him a chance to recover. She slammed her full throat down onto him, swirling her tongue around the aching mast as Denji saw stars. It was overwhelming to say the least. Even though it should have been pained to be up again, his cock was buzzing with sensation as Power sucked him off. An overload of pure pleasure washed over him. And it wasn’t long before he was pumping meat juice down into the sweaty demon’s stomach.

But this was far from the end.

With the power to embolden, embiggen, and empower his penis, Power had really powered up their pound town power coupling, as they say. They may have been already four hours deep, but the next five hours were an equal blur of thrusting sweaty pleasure.

It was hard to even be that mad with her. His senses were sort of there. Dulled by the lack of blood flow, but present enough to know he was still enjoying himself. All the positions they were trying, all the cum flowing into her holes, all the roughness and tenderness… it was fucking fun.

Power was in control of his body and she using it to fuck herself senseless… honestly? Women had done way worse. This was fine as hell.

When it was finally over, when the sun was beginning to rise and Power had finally exhausted herself, collapsing beside him in a boneless heap, Denji just stared at the ceiling. He was pretty sure he'd had at least three out-of-body experiences. One of them being a strange door… before he was greeted by Pochita telling him to get his ass back down to fucking Power. His entire body ached, but in a good, deeply satisfied way.

Power snuggled up next to him, placing her hand on his dick like a territorial house cat with their caught dangly toy. “You may now rest, Denji,” she murmured in her sleep. “As your reward, you may grow your penis big and hard for me tomorrow, k?”

Denji just sighed. She was definitely doing something to his cock, he could feel his blood moving about again, but he was too exhausted and satisfied to move. He just closed his eyes, assuming tomorrow may just be the last day of his life, but smiling knowing he was to die in the way he’d always dreamed.

Death through too much sex.

But Denji didn’t die. He got to live through all of it. Creampies, cowgirls, French kissings, titty fucks, full nelsons, shower sex, late night sex, early morning sex, sex with food, sex on food, red sex, blue sex, more sex than you can shake a stick at. ALL of it. No matter when, where, or what he was doing, Power would find him and extend his cock with her blood bending. She was getting good at filling his balls with cum now too, every day becoming more confident in her ability to suck n fuck his literal brains out.

There was a significant increase to his cock size and stamina too. Whatever Power was doing to his testosterone was making him crave it more now, filling her pussy with much less complaining than the first few days.

And then it extended to Aki.

There had been a lot of yelling. ‘Demon spawn!’, ‘Freaks!’, ‘Animal-brained morons!’, so what if they’d fucked in Aki’s bed? They were running out of dry surfaces.

Denji had bragged about his new arrangement with Power. Claiming it to be greater than anything Aki had ever felt with his dick, and he was probably just jealous of all the sex he and Power were having. However, the news that Aki even owned a penis had been new info to Power. Ever the opportunist, she quickly tried growing her other human pet in the same location.

It had looked just as overwhelming as it had felt to Denji. That blank eyed stare as his cock filled with an absurd amount of blood and cum. Aki grasped at his cabinet, maybe trying to run, maybe just trying to hold himself together, but it was too late. Power beckoned his blood closer, ripping open his pants before letting him fuck her cum filled cunt like a rutting monkey.

“Haha! President Power is a true genius!” she declared as Aki humped her hard, “Now I can suck Denji while Aki fucks me! I have invented even better perpetual motion than Chainsaw Man! Praise me with your penis, Denji!”

They barely left Aki’s room for two days.

With a new source of meat juice, Power could quite literally go on and on. Aki had moments of clarity where he threatened her life, but they were quickly ignored for another round of sweaty erect sex. Denji was just happy that Power was so greedy. If she was a pervert she’d probably make him suck Aki or some shit. Instead, she just wanted them both to fuck only her.

After that, Aki’s apartment descended into a state of perpetual horny depravity.

Denji and Aki didn’t tell their boss about Power’s newfound erection ability. They were now her toys, living existence in a constant state of semi-arousal that kept their groins thrumming and their balls full. Yet, the orgasms Power kept dragging them into were incredible. Denji described it like he was always doing a month of no-fap before getting to cum buckets down Power’s throat, Aki told him to shut up.

That ache that could turn into a raging hardness at the mere wink in their direction was hella addicting. Some days they’d be arguing about this or that, dicks half hard while they fought over the last of the cereal, and then Power would appear. She’d just place her hands on their huge cocks, jerking them off into the last bowl and then eating it herself while they just puffed away.

Whenever Denji wasn’t fucking her, Aki would be right there instead.

Sometimes they even fought over her. Trying to uncharacteristically out-alpha each other while one was in her pussy and the other in her ass. Once they even dueled swords inside her pussy itself.

Mornings were a blur. Aki would be trying to make coffee, his boxers tented, when Power would casually saunter over, drop to her knees, and start sucking him off right by the counter. Denji would then be summoned from his room like his dick was trying to find water, diving right into her booty before stealing Aki’s coffee.

Evenings of TV, half crafted dinners, and sex. Power used to care a little about cartoons, but these days she was just too focused on meat juice. Barely letting the men breathe before filling her pussy with either of their dicks.

Eventually they did need to go back to work, but that didn’t stop Power at all.

The effect just rippled out from their apartment to infect the Devil Hunter headquarters like a viral sexy disease. Power may have been summoned to the office, but she quickly found herself in charge of the grunts sent to cease her addiction. Even higher ranking agents would fall to her. It was seen as novel at first, just a place to get your dick sucked by the Blood Devil.

But it grew. Oh did it grew.

By the time it reached Makima, most of the men were feeling drained. Their minds dulled by the constant dopamine and blood bending that Power provided. It was akin to the zombie devil’s influence. Throws of top agents all standing around like pants down shambling mounds as Makima strolled casually through the horde.

When she reached the bathroom, it was almost hard to tell who was behind it all, there just was so much cum covering her. But the horns poked through enough for Makima to understand what had happened.

“That’s enough, Power. Put all the blood back into these men’s brains. Now.”

Power looked up, having to wipe some cum from her eyes to see who was speaking. She’d always recoiled in fear from Makima, which is why it was so surprising when she just said: “Nah.”

“Excuse me?” asked Makima.

“You don’t scare me anymore!” hissed Power, standing up from her place in the center of the bukkake with a snarl to her jagged teeth. Cum still dripped off of her, and her point even made a bit splatter onto Makima’s shoe. But Power just kept pointing. “I have the power of endless Meat Juice! Power is gonna bring world peace! Power will become bigger than the president, we’ll get Power the Pope! Now, Pope Power will put you in your place, foolish ginger demon! HIYAH!”

Makima smiled at the gesture Power made towards her groyne. “Hm. I suppose you’ll have to d-AHN~!”

What she’d failed to realise was that there were plenty of women also affected by Power’s blood bending. She’d made it a point to learn all about how a woman could get horny when Kobeni was sent to retrieve them a week ago. Power had watched Kobeni go from a gutless human guinea pig to a wanton slut, almost as ravenous for meat juice as Power. A constant thrum of woman juice poured from Kobeni now, becoming one of Denji’s favourite toys to fuck.

Makima felt a strange, internal pull. Her womb was boiling to the point of insanity almost immediately. Her blood shifted, heated, transforming her brain to send pheromones and fertile eggs for seeding. Makima lost control of her body almost immediately. Her nipples hardened, her pussy soaked through her panties, and suddenly all she could think about was sex.

And there was almost no blood left in her brain to argue otherwise.

She fell to the floor in shock, suddenly so glad to be surrounded by her men all aiming their cocks at her. Power started stripping Makima as the boss’ mouth started sucking any cock she could. Tongue lapping up precum in the hope that thicker juices were soon to follow. She may have been a demon, but her body was human enough to feel the pull of pure lust to be bred.

Power gifted her second pet, Aki, with the chance to be the one to fuck Makima first. It meant nothing to her. She wanted meat juice, and now she had the whole office worth of meat juice to consume in her leisure. Power just didn’t want any other woman getting in her way, and all these human pets were much more docile in this reverse spayed state.

She’d probably let Denji fuck Makima too. He was still her best meat juice maker, and was probably the most conscious still despite the changes. Perhaps he was just used to working his brain at mostly horny and low thought altitudes, but he wasn’t smart enough to stand up to the overwhelming boner power of Power.
