Chapter Text

"Ngh...! Nagi..." Reo whimpered through gritted teeth.

The purple-haired boy was panting on top of his sheets, eyes glazed as he slides his middle finger up and down his slick cunt.

He closed his eyes and a boy with mop-white hair materialized almost instantly. 

Nagi. His best friend of almost three years now. 

Reo had lost count of how many times he's lost himself in pleasure while thinking of Nagi. He's not supposed to do it, not to his best friend. He knows that but he can't help it. What started as a small tingle in his heart became an ache that consumed his whole being—gnawing, thrashing, begging to be known. 

He realized his feelings when they were in Blue Lock. When Nagi scored that amazing goal against the Japan U-20 and he whipped his head around to look at Reo, eyes bright, full of excitement and pride. Reo's heart swelled. He had to fight every muscle in his body to not run to the field and take Nagi into his arms. That's when it came crashing down on him. That he likes his best friend. 

Suddenly, everything made sense. Why he felt so deeply and utterly betrayed when Nagi left him in the second selection, and why he felt like death when he didn't choose him again after losing the 3v3. 

Reo shook his head to redirect his thoughts and imagined Nagi moving above him. How his huge hands would feel gliding across his bare skin. Would he take him fast and rough? Or would he sink into him inch by delicious inch? 

Reo's toes curled at the sinful imagery. God, Nagi's so fucking hot. He had to bite his lip to stop screaming Nagi's name.

His clit throbbed hard, aching for more. In his mind's eye, it wasn't his hand but Nagi's mouth on his sex, tongue engulfed in the wet heat, gulping every bit of nectar his poor pussy gushes out.

Reo's tongue darted out to wet his bitten lip. He can't last much longer and so he jerked faster, abs flexing as a delicious knot formed low in his core. His fingers travelled lower, to the slick pooling at the apex of his thighs and pulled them up to continue his assault at the sensitive bundle of nerves, fully coating it with his fluids.

He felt himself climbing higher and higher, thighs quivering until they’re almost numb. He’s so close, he’s so close, he’s com—

“Ugh!”

Reo’s eyes darted wide open as he heard a soft thud followed by pain blooming in his chest. 

What the fuck was that? 

He willed the lust-filled haze that was his brain to start working again while he worked to catch his breath. With wobbly legs, he ran straight to the full-body mirror across his room to look at his chest, still rising up and down due to his earlier activity. He inspected the expanse of white skin and the little hairs that littered it. Nothing. No redness, no wound, the smooth skin undisturbed.

Weird. He definitely felt pressure there a few seconds ago. Like something dropped on it. Something heavy. Did he fuck himself into having a heart attack? His blood ran cold at the thought. If this really is a heart attack, he needs help and he needs it now. Ba-ya, he needs Ba-ya to take him to the hospital.

He reached for a robe and ran towards the door. Just as he was about to scream loud enough to wake the whole house, he heard a voice, a woman, shouting in his ear.

[Stop!]

Reo whipped his head around to locate the intruder but saw nothing. It was just him in his huge room. They must be hiding. Where? In quick strides, he was in front of the bathroom door and swung it open. Nothing. 

“What—”

[I’m here.] The woman said, voice sounding awfully close to him that Reo almost feels her breath ghost his neck.

“W-where? Who—” 

[Inside you, buddy. And no, you’re not dying, at least not yet.] 

Inside him? What the fuck does that mean? Reo stared at his reflection in the mirror, purple eyes blown wide in confusion. He looked around the bathroom again. It’s still just him. He shook his head, his brain must be fucking with him. 

He remembered the pain in his chest which was mostly gone now. Still, it wouldn’t hurt to get it checked, right? He left the bathroom to rouse Ba-ya.

[I told you, you’re not dying yet.] The exasperated voice rang in his head. 

Now, Reo’s sure he’s not just imagining this thing. Someone—something is talking to him. 

[Not if you have sex until the gauge is full.] 

What? 

“Who are you? Where are you? What are you?” Reo felt crazy talking to himself, eyes darting around the room to look for the owner of the voice. “And what gauge?”

The woman sighed like she couldn't be bothered to answer all these questions but relented nonetheless. [Okay, first of all, I’m not telling you my name. That’s confidential information. I told you earlier, I’m inside you. In your body.] 

Reo looked down at his chest again. Inside him. So that pain earlier…

[Yes, that was me. I’m a succubus and I feed on human males' vitality to survive, if you catch my drift.] 

Reo’s not stupid. He’s read about succubi before, in literary books and in hentai mangas he’s stumbled into while jerking off. They’re sex demons that require semen to survive so they prey on pathetic humans to milk. At least that’s how it usually goes in porn.

But that was porn—fiction—and this is real life. Reo does not believe in the supernatural. He’s always believed in things that have real, scientific evidence rather than whatever fantasy the human mind has conjured–from fairies to religion. This has been true ever since he was young. He’s never believed in Santa or the tooth fairy because whatever they could give him, he could always ask for something better from his parents.

Is he going insane? Has three years of pining after his best friend finally fried his brain cells? 

[Stop denying me, boy. Look at yourself.] The woman groaned. Reo had no idea what she looked like but he could almost see the woman rolling his eyes at him. 

Just as the woman—succubus—said that, something white hot crawled from his chest to his navel. He walked to the mirror again and opened his robe. There, above the soft tuft of his pubes, right where his womb would be, glowed a pink, heart-shaped mark. Just like the one in the hentai mangas. 

Bringing a hand down to the mark, he tried to rub it away, but it didn’t go anywhere. It sat there, branded on his skin, faintly glowing.

What the fuck…

[Do you believe me now?] Reo could hear the smirk in the woman’s voice. 

“What do you want?” He breathes, unblinking eyes fixed on the pink mark on his skin.

[I want, no, I need you to have sex with a man, or men if that’s what you want. I need them to cum in you until the mark is filled.] The woman said it so matter-of-factly like she’s just discussing how she likes her coffee and not asking Reo to have another man cum in him. Reo wanted to laugh at the absurdity of the situation. 

Reo eyed the empty space inside the heart. 

“And why would I do that?” Tone indignant, he locked eyes with himself through the mirror. 

[So I could get out of your body. Don’t you want me to be out of you as soon as possible? Well, I’m weak so I need energy to detach myself from you.] Reo did not need to ask what type of energy she needed. 

What does that have to do with him? Yes, he could follow the succubus and fuck someone until he’s filled the gauge easily. He really does not lack admirers willing to jump into his bed at the drop of a hat. Something about the Mikage name, his charm, or his face, or a combination of the three, endear people to him. Reo, being Reo, always liked to think it was the money and prestige that comes with his last name that pulls people into him though. 

But following the succubus, why would he do that? He’s an unwilling participant in this and he doesn’t want to be a part of whatever the fuck this is, thank you very much. Reo’s mind raced, thinking of different scenarios to get the demon out of his system. 

After a short while, he’s resolved to just letting the demon starve. Surely, if she dies, she’d leave his body, right? 

He heard, no, he felt the woman’s chuckle vibrating across his body. 

[You could do that, yes. Let me starve and die. I would just like to remind you, though, that I’m in your body. We’re one.]

“And?” Reo had a bad feeling about what she’s going to say next. His fist balled into fists at his side. 

[And if you do that, you will die.] Reo felt his stomach drop. Before he could even command his body to, his hand palmed at the mark again, wishing it would smear and disappear. But the mark stubbornly stayed where it was, like a tattoo, bright pink, taunting him. 

[You could try starving me but that would also be the end of you. As for me? My energy will disperse and it’ll take me a few years to gather myself but I won’t die.] 

Reo let go of the breath he didn’t know he was holding. He felt helpless, drained. He walked towards his bed to lie down and closed his eyes. Maybe this is just some sick nightmare and he’s fallen asleep after his wank session earlier. Yes, that must be it.

He sighed. After a beat, he heard the demon sigh too. [I’ll just pick a better human next time.] 

He cursed the demon in his mind. 

Why me? 

The succubus did not give him an answer. 

 


 

When Reo woke up the next morning, the first thing he did was check the mark on his navel. He groaned when he saw that the mark was still there. Pink and so very real.

[It’s real, boy. I keep telling you.] Was all the demon had to say. 

“Shut the fuck up,” he said through gritted teeth. He could hear the demon’s smile and there’s nothing Reo wished to do then but to strangle the succubus and then himself. 

He went down and scarfed down the breakfast Ba-ya prepared and made his way to the car. As soon as he settled down at the back of the limousine, he felt his stomach growl. He rolled his eyes.

[As long as I’m in your body, human food won’t sate you.]

“Yeah, thanks,” he snarled.

Ba-ya opened the window dividing the driver’s area from the back of the car. “What is it, Reo-sama?” 

“It’s nothing,” he murmured.

Reo felt it in his chest when the demon giggled.

[You’re welcome.]

 


 

Throughout the day, Reo tried hard to ignore the clawing in his stomach and focused on his lectures instead. But, gods, is it hard when all he could think about was stuffing himself full of food. It was no use to eat though. Like what the succubus said, that would not be enough. 

Reo had been snacking all day too. Hoping that it would work so he could get rid of the wobble in his knees from the lack of energy. He finished the last of his protein bar only for his stomach to vibrate again. Fuck. 

[You know what you need to do, boy.] The demon jeered, sickeningly sweet voice ringing out in his head. 

Whatever retort Reo had was interrupted by the sound of the LINE notification from his phone. 

It was Nagi. 

Nagi: where r u

Nagi: im done w practice. dinner?

Reo’s breath hitched. He missed his best friend and his mouth watered at the thought of dinner (and Nagi). He collected his things and stood up only for his knees to buckle under his weight. Of course. 

Fuck this succubus. 

[I wish that for you too.] She chuckled. 

Reo wished he could murder the demon inside him. 

[Maybe you could ask this Nagi to fuck you.] 

He scowled as he made his way out of the lecture hall. 

“Don’t,” was all he could say. 

[Why not? You’re holding a torch for this boy, aren’t you? You were fucking yourself to the thought of him fucking you last night.] Reo closed his eyes as he felt his face heat up at the memory of him jerking off to his best friend. The succubus saw that? 

[I can see and hear your thoughts, you know. He could be, what do you youngins call it? DTF, no? What’s the harm?] 

What’s the harm? Reo wanted to laugh. He’s not even sure if Nagi likes boys. During the whole time Reo’s known him, Nagi has never shown interest in anything except for football (well, there’s Isagi, but as far as he’s concerned, nothing really happened between the two of them). And even if Nagi’s interested in boys, that doesn't mean Nagi's interested in him. And he sure as hell is not ruining their friendship for a quick fuck. No.

“Would… would a blowjob not suffice? You said all you need is semen right?” Reo couldn’t believe he’s asking this. Couldn’t believe he’s actually going with the succubus’ schemes. But he’s so, so hungry. His knees feel like jelly and his hands are trembling. He needs to do something about this quickly. 

[It could, but the gauge will fill up slower. You think you could suck dick maybe a hundred times?] The demon taunted. Was she enjoying this? Reo did not want to know the answer. 

[Think of it like chips, maybe? Blowjobs are not filling like those garbage. While sex is like eating Ichibo steak.]  His stomach growled louder than it ever has at the mention of his favorite food. This damn demon.

[No condoms. That’s important.] The demon added, disgust evident in her voice. 

Reo sighed. 

He quickly typed an apology text to Nagi, saying he’s busy with school work, and promised that their next dinner would be on him. 

It sucked because he wants nothing but to see his best friend right now, to laugh about how fucked up this whole situation is with him. 

Nagi replied almost instantly with a ‘got it’.

When he got to his car, he instructed Ba-ya to drop him off at a club several miles from the campus. Ba-ya looked at him with questioning eyes but whatever question she had for Reo, she did not voice it out. 

 


 

It took a few seconds for Reo's eyesight to adjust to the dim lighting of the club. Blue and purple strobe lights danced all around him, the bass booming so loud he could feel it in his chest. 

He pushed past the sea of sweaty bodies to get to the bar and ordered a tequila. He's about to give someone head and he doesn't think he can do it sober. Just the thought of having someone in his mouth, someone that isn't Nagi, is enough to make him want to puke. He downed his drink in one go, ignoring the heat that made its way down his throat. 

“One more,” the bartender obeyed and within seconds, he was downing his second drink too. 

The alcohol burned and his throat felt like death. Through gritted teeth, he asked the bartender for another one. He threw his head back to let the liquid slide down easily. It hurts and it doesn't taste good but he needs to do this. Needs the liquid courage to do the magic for him. Maybe when he's inebriated enough, he would be able to go through the motions and forget about this shit when it's over.

Reo felt his face heat up. He needs more. He was about to ask for another drink when someone spoke just beside him. 

“If it isn't Purple Bun,” the owner of the voice hummed. 

Fuck. Shidou Ryuusei.

Reo craned his neck to look at the tall, antennaed freak, sporting a joker-like grin. He's still sporting his famous eyeliner and Reo wondered how he gets it even all the time. His gaze moved down Shidou’s chest. The first four buttons of his shirt were undone, showing off his tanned skin. 

[He's perfect!] The demon inside him exclaimed. Reo could feel the demon's hunger, looking at Shidou like he was the main course of a gourmet meal.

“Where's your white mutt, Top Knot? Did you two finally break up?” Shidou took the seat beside him without being invited and asked for two more drinks for each of them. 

Not one to be discouraged by the lack of reply, the freak continued, “Drinking your heartbreak away?” Shidou teased, his eyes glinting like he found a goldmine. Of all the people that could spot him, why did it have to be Shidou? He cursed the gods and the succubus for his misery.

“No.” Reo scowled. Breaking up when he and Nagi were never even something to begin with? It was laughable. But Shidou doesn't need to know that so he didn't offer any explanations.

He accepted the drink Shidou got for him and poured it straight down his throat. Out of the corner of his eyes, Reo could see Shidou's smirk, and what he wouldn't give to erase that from the freak’s face right now. 

Shidou did the same to his own drink, throwing his head back, pink and blond bangs following his movement. Reo caught the way the other man’s Adam's apple bobbed as he downed the drink. His stomach twisted in hunger. 

[This is the one. Go on, ask if you could suck his dick!] Reo could feel the demon licking her lips, not fully aware that he mirrored the action too. His stare moved from Shidou's throat to his exposed chest down to his…

Shidou followed Reo's gaze, shit-eating grin still plastered on his face. He leaned in, hot breath fanning Reo's cheek, making the purple-haired boy shiver.

Voice sultry and low, the other man asked, “Do you wanna get out of here, my little Purple Bun?” 

With bated breath, Reo nodded, and Shidou wasted no time to drag him out of the club.
