“So you only eat jello and water?”

Nagi looked up from his phone to see Isagi staring inside his minifridge. Nagi had reluctantly agreed to invite his friends over for a birthday party of sorts - Reo’s idea, not his. It seemed like Nagi’s 18th birthday was a good enough reason for celebration. And Isagi had arrived as early as 10am to find his much taller friend still fast asleep.

“It’s easier.” Nagi said dismissively as he continued to tap away at his phone.

“Still, what’s in the jello that you’re surviving on it alone?” Isagi said before grabbing a packet of it and examining its packaging. “I don’t even recognize the brand, where’d you get this from?” Isagi wondered aloud before twisting open the packet’s cover, and hesitantly taking a sniff.

“My parents send me a box every month.” After Nagi entered boarding school and his parents swiftly moved abroad, they would send enough jello to survive the month and maybe some extra. Nagi didn’t have , and quite frankly didn’t want a job so he was relieved to not have to spend anything on meals.

Even so Nagi had plenty extra as he only really ate some whenever hunger compelled him to.

“It doesn’t smell like anything… Can I taste it?” Isagi asked, taking the packet away from his nose, the lack of scent was a little unnerving. “You’ve already opened it so…”

“I’m sorry, I’ll put it back.”

“It spoils quickly after you first open it, either drink it or throw it away.”

Isagi sighed as he closed the minifridge and brought the suspicious jello to his mouth. Taking a reluctant sip, Isagi almost dropped the packet as he swallowed the gelatinous mixture. It tasted like nothing, not a hint or trace of any memorable taste. Isagi could only be surprised at how little his taste buds gathered from the jello. Even the air had more taste than this.

Eyeing the half-full trashcan, Isagi felt his taste buds crying for him to throw the damn thing away and spare them but Isagi didn’t want to waste his friend’s food. Luckily the serving was small enough and Isagi was able to finish it in fifteen painstaking seconds.

“You could have thrown it away.” Nagi said seeing Isagi’s struggle was a bit amusing.

“You’re telling me this now?” Isagi could only laugh shyly without the horrible non existent taste of the jello resurfacing

–

“So Nagichii, how do you like your meal?”

Bachira asked, eye-ing Nagi’s half empty plate. They had been in the restaurant for close to two hours and Nagi was the only person out of the group’s seven that hadn’t finished their meal.

“ I don’t normally finish meals.” Nagi said as he poked the cold meal on his plate, hoping it would magically disappear.

“Let’s have the waiter pack it up then, you need more actual food in your house Nagi.” Reo helpfully suggested before waving down a nearby waiter. Nagi wanted to tell Reo that he most likely would forget the meal existed if he took it home, but before he could the meal had already been carried away into the back of the restaurant.

“Well Nagi, how do you feel knowing you’re going to be an adult tomorrow?” Chigiri asked. To Nagi, the whole ‘getting-older’ thing was just something that happened. “Yeah Nagi, are you going to get your license?” Isagi asked. Imagining himself behind the wheel was already exhausting him where he sat.

“Oh Isagi, you can tell he doesn’t like that idea.” Barou remarked, looking at the grimace on Nagi’s face.

“If only Nagi was 21, then he could buy alcohol.” Zantestu said, looking down at his empty cup. The rest of the table however was looking at him.

“Well…It’s late enough, I should get going,” Barou said, reading the clock hung on the fancy restaurant wall behind Nagi’s head. The sun had long set outside, but you couldn’t tell by the bright ceiling lights of the upscale restaurant Reo had brought them to, “Thank you for the meal, happy birthday Nagi.”

“We have to go too,” Chigiri said, only noticing the time now. Zantestu and him had arrived together as they surprisingly lived very close to one another. Chigiri found out when he saw Zantestu barely make the train they would take to the side of town where the group agreed to meet up.

“Well then, as Nagi’s appointed birthday host, thank you all for coming.” Reo said before ordering one last round of drinks for them to take home.

By the time Nagi made it back to his apartment he was a few steps away from passing out, he couldn’t imagine the last time he was so happy to see his bed.

He didn’t have the energy to look at the time or even change out of his clothes before he passed out, sprawled across his bed.

–

When Nagi woke up, the first thing he noticed was an intense feeling of hunger in his stomach. Which surprised him as he normally and even often could go a full day without eating and feel fine. The next thing he noticed was the feeling of heat pooling in his stomach attached to the deep-rooted hunger he felt. First day as an adult and he woke up feeling like this?

Nagi could only sigh before reaching for his phone conveniently next to him.

Dead. Great.

After setting his phone down to charge, with nothing else to do, Nagi forced himself up and towards the mini fridge. Opening it, he grabbed a jello packet and in no time drank it empty. Unfortunately for him, the immediate fulfillment he normally experienced was nowhere to be found.

Weird. Nagi reached for another one and drank it just as quickly.

‘No. still hungry’ Nagi groaned before his eyes landed on the packaged meal from last night. He hadn’t left it in the fridge overnight but it should still be okay to eat if he microwaved it right?

As Nagi started the microwave’s timer, he was thankful Isagi had forced him to get one. The shorter’s excuse was for widening his taste with -at the very least- ramen, but Nagi hadn't touched the thing since he bought it months ago.

Unfortunately Nagi only owned a pack of paper plates and a few disposable forks so it would have to make do.

Luckily the food looked good enough after three tortuously long minutes. By the time it had finished though, Nagi was hungry enough to eat the microwave itself.

Once the microwave door automatically opened, Nagi reached into the microwave to grab the food, seemingly uncaring of how his hands burned red upon touching the food.

Like a man possessed he brought a handful of the warm french fries to his mouth.

What the fuck.

The moment the taste of the fries touched his tongue, Nagi had to spit the food out. It tasted disgusting. ‘Is that even food?’ Nagi thought as he looked at the spat out food on his counter. Maybe microwaving the food didn’t help as much as Nagi thought it would. It was still weird however, the fries he just chewed now tasted nothing like how they did yesterday.

…

So what if they tasted horrible, Nagi still needed to eat something.

Reaching back into the plate he grabbed another handful of french fries and forced them down his throat. His stomach churned violently, a nauseous wave building as the putrid taste hit him. He forced himself to chew in an attempt not to choke. His eyes watered, and he could feel his body fighting the food back up, but he swallowed hard.

After a few seconds and he knew he wasn’t going to vomit it all back up, he finally relaxed small. Looking back at his bed, he had the idea to let his body finish digesting the food as he slept, and hopefully he would wake up energized again.

Sounded like a plan.

Once Nagi woke up again, he felt so dizzy he could faint. To his dismay nothing was working, he was still so hungry he felt like dying. Annoyingly enough, something slim and wiry had rolled underneath him as he slept. Nagi paid it no further thought though. With his phone being charged now, he opened it.

May 7th XXXX, 1:26am

Nagi rubbed his eyes, thinking the words displayed would change. However that was not the case, as he removed his hands from his face the information didn’t change. He had slept throughout the entire day

Nagi could feel panic rising in his throat, he was going to die like this. Maybe it was the lack of a real diet that was catching up to him. It couldn’t be, he had eaten like this for years, it wouldn’t be now that his body decided to revolt. Or maybe the hunger was making him delirious as well as deathly tired.

He could feel hunger and fatigue threatening to force him unconscious once more. Nagi could barely keep his eyes open as he opened his friend group’s group chat

Nagi: I love you guys

So now if he died, at least it wasn’t without a goodbye. He hardly doubted any of his friends would be up but at least he put it out there. Nagi wouldn’t say he was afraid of death, maybe because it seemed so far removed from him. But now as there was a true chance he wouldn’t wake up from this, he couldn’t lie and say he wasn’t a bit scared.

–

Isagi was so tired. It was long past midnight, and unlike him, Isagi found himself wide awake on his bed. If Rin was here, he’d berate him for being a ‘half-baked’ striker for not giving his body enough rest.

Still the clock only read 1:25am and the match wasn’t scheduled until 3. Somehow, he didn’t feel tired at all. Unfortunately he kept his laptop a few feet away charging, so he only had his phone for entertainment.

While in Blue Lock he had gotten used to not having a phone around that now at home for a break he almost felt like a grandma discovering new technology. At least on his laptop he could play a game or two while he waited but he wanted it charged for 3am.

*You have received one notification from XXXXX*
Nagi: I love you guys

Isagi had never shot up quicker in his life. All traces of tiredness gone in an instant

Before Isagi could think his actions through he ran to the train station, praying there was some late night train to take him to Nagi’s neighbourhood.

Isagi knew Nagi, he knew what things he enjoyed and most importantly at the moment, the kind of person he was. And the Nagi Isagi knew would never send a message like that at 1am in the morning unless he was about to do something drastic - or dangerously stupid.

After around 10 minutes, Isagi stood at the door of Nagi’s apartment. Without thinking, he had come here with no idea of how he'd get inside. In a rush he fiddled with the handle and like magic it opened up for him. If Isagi was worried about the message, the fact that Nagi’s door was unlocked only tripled that feeling.

“Nagi… are you okay?” Isagi said, rushing into the apartment. The blinding lights of the room were a severe contrast to the pitch black of night. This meant that he could see Nagi’s entire apartment from the door.

And, unlike he feared, Nagi hadn’t decided to kill himself.

Instead, he was curled up like a morbidly obese cat underneath his plain white sheets. A tidal wave of relief washed over Isagi once his over-imaginative brain realised he had come for apparently no reason.

Well it was far too late for any other night train to take him home; he would just have to get comfortable in the other’s bed. Luckily he had managed to not forget his phone in his initial rush to get here, so he texted his parents a quick explanation of where he was.

Having a deeper look around the room, Isagi noticed a pile or spit out food on Nagi’s desk. His mouth contorted in disgust, it didn’t look like throw up, but Isagi didn’t want to look at it any further to figure out what it could be. Nagi wasn’t exactly the cleanest person ever, but c'mon this was gross !

If Isagi was a different person, he would suck it up and find some place comfy to sleep. But Isagi couldn’t relax knowing that was in the same room as him, so begrudgingly he found one of Nagi’s dirty shirts to scoop it up. He thought of trashing the sullied shirt but the clothing wasn’t his. Looking around his room, Nagi didn’t even have anywhere to put his dirty clothes. Did he have it shoved away somewhere? How did he get his clothes clean?

“Isagi?”

The sound of Nagi’s… oddly awake voice startled Isagi from his very important decision making.

“Isagi… I’m so hungry.”

Isagi turned around to see the white-haired man standing just behind him. Nagi’s frame always dwarfed Isagi’s own and from where Isagi stood, the room lights were blocked by Nagi’s sheer height.

“Hi Nagi,” Isagi began, trying to avoid the taller’s eye. Isagi wasn’t normally scared of Nagi, but the look in Nagi’s eyes today was different.

“I’m sorry for intruding, I was just worried. I would have left but there’s no way for me to get back home until tomorr-”

“Can I eat you?”

Isagi's eyes snapped back to meet Nagi’s. The other man had to be joking : maybe too sleep-deprived to understand what he was saying. But maybe Isagi himself needed some rest because he didn’t automatically assume Nagi was joking.

“Cmon Nagi, we’re both too tired to be making jokes right now.”

Despite all his efforts to seem unaffected, Nagi’s glare seemed to strip him bare of all his defences. By the look on Nagi’s face, he had longed to stop listening to him. His eyes had trailed downwards and found a moment’s rest at his lips. Due to the fact Isagi was much smaller than Nagi, he was able to follow the other’s eyes all the way down.

“Are my lips that chapped?”

Silence. The room was dead silent, except for the heavy breathing Nagi had begun. His bare chest rising and falling with every second of his intrusive gaze.

Isagi wanted to try once more to break the silence. His lips opened again to let out another question, or perhaps this time a stale joke.

“I-”

In a moment, Isagi felt his lips being taken into a searing kiss. Nagi's lips were ice cold upon first contact, but rapidly started to heat up as if trying to fit towards Isagi’s preference.

Then, a shiver went down Isagi's spine as Nagi's tongue, as if under a spell, traced the seam of his lips, seeking entry. As Isagi's mouth parted slightly in surprise, Nagi's tongue forced its way inside. Like a man possessed, Nagi used his tongue to thoroughly explore every inch of Isagi’s mouth. His large hands went from being stationary beside him to reaching under Isagi’s legs and lifting him until his legs were tightly wrapped around the other’s waist.

Isagi could feel his tongue being played with like a chew toy. At first he tried to push against Nagi’s grip and free himself but at some point he could feel his will to fight back diminish into nothingness. Suddenly he wanted to kiss back with all he had.

The feeling of his admittedly small frame pushed up against Nagi’s large chest was only further fueling the flames of arousal within him. A feeling he wanted to chase and see where or even if it ended.

Unfortunately, Nagi decided to pull away the moment Isagi fully leaned in.

“Delicious...” Nagi muttered between oxygen-deprived huffs, drunk on the taste of Isagi on his tongue.

Still carrying him, Nagi stepped backwards until he found a comfortable seat at the edge of his bed. Nagi had set down his friend on his lap, facing him. After that whirlwind of a first kiss, Isagi floated back to reality to meet Nagi’s lustful gaze. This time his eyes had changed from a chilling grey to a fiery glowing red.

Were Nagi’s eyes always that colour? Isagi couldn’t hope to remember

Deeply distracted by Nagi’s eyes, Isagi didn’t notice the feeling or a thin tail tug at the waistband of his shorts. The feeling of something sharp poking at his side snapped forced his eyes away from Nagi’s.

Was that a tail?

The tail was long, thin and black with a heart shaped end that was currently trying to strip him where he sat. Isagi’s eyes traced the tail back up to see that it disappeared behind Nagi, the tail itself probably coming from him.

All of these new found discoveries were confusing. Humans didn’t have tails, Isagi knew that one for sure. A sounder, more logical, and definitely less horny Isagi would have pieced together the puzzle and gotten out of there quickly. However, the Isagi now was too curious to see where this would lead, and much too curious to see where Nagi would take it.

Sensing that Isagi’s attention wasn’t solely on him, Nagi’s mood bittered. His large hands snaked around Isagi’s waist before moving the smaller boy closer to himself. Looking down at Isagi’s waist, it was so small in Nagi’s hands. Nagi wanted to see more.

Nagi’s tail, seemingly following the will of its owner, slithered its way up from Isagi’s waistband to his shirt. Unlike Nagi’s cold skin, the tail itself was burning hot. The overwhelming heat of it didn’t allow for Isagi to take his eyes off of it. And before he knew it, the tail had managed to leave him shirtless on the lap of one of his closest friends.

“Pay attention to me.”

Isagi’s eyes slowly moved back to Nagi, only noticing now how the other’s hands were secured tight around his waist.

With his attention brought back his way, albeit briefly, Nagi’s tail had used the very edge of its tip to slice through Isagi’s shorts. Like paper, Isagi’s shorts fell off his body to reveal his full naked form. Nagi looked down, looking forward to admiring Isagi for all he was.

“No!” Isagi protested, only realizing his situation now. His hands reached to cover up his crotch and seal them away from Nagi’s prying eyes

“Cmon -sagi.” Nagi pleaded, finally taking his hands off the other’s waist and steadily pushing Isagi’s own off his crotch. Isagi found himself not fighting against Nagi’s grip, if anything he found it deeply arousing how much stronger the other was compared to him.

Nagi eyes widened the moment they laid eyes on Isagi’s erection. Isagi was much larger than Nagi expected. Probably was the same size as him, if not bigger, which was impressive considering their size differences.

“You’re freaky big.” Nagi spoke as if stating a fact.

“I told you to stop.” Isagi said, shying away from Nagi’s studying gaze of his dick.

“I wonder if that’s tasty too.” Nagi muttered to himself, although loud enough that Isagi was still able to hear. Nagi’s eyes had gone from a fiery red to a burning inferno. However, his inner turmoil was interrupted by a loud growl. Nagi had forgotten he was still hungry.

In an instant Nagi had used his raw strength to flip their positions. One moment Isagi was sitting only a few inches from the other’s erection, in the next he was the one sitting on the edge of the bed, while Nagi kneeled between his spread legs.

“Nagi?”

Nagi took the confused teen’s dick in his hand. It really was big, Nagi could barely fit the entire width in his hand. Testing the waters, Nagi took an experimental stroke. Not even needing to look back up, he could feel Isagi tense at the dry tug.

Ah yes, lube.

Nagi looked around his room. If he remembered correctly, he had a lotion in his nightstand that would be perfect at this. Not wanting to stand up, Nagi’s tail reached out but unfortunately couldn’t work the nightstand drawer’s handle.

Nagi eyes gave one more longing look at Isagi’s inviting package before standing up to get the damn lotion himself.

“Nagi.”

Nagi paid no mind to the other’s words as he resumed his former position, only now with a bottle of vanilla scented lotion.

Wait. When - not if, never if- he was going to suck Isagi off, wouldn’t he taste the lotion?

“Nagi please…”

Isagi tone’s had transformed into a needy whine. Isagi’s hands were glued, shaking at his side as if Nagi demanded him to keep them there. The shorter boy was bending along to Nagi's every whim. For a man so dominating on the field, he surely knew his place in the bedroom.

Nagi could only slyly smirk before he took Isagi’s throbbing length into his mouth, only stopping when he could feel the other’s tip touch the back of his throat. Surprisingly, Nagi had almost no difficulty fitting the other into his mouth, infact his body seemed delighted to accept the intrusion.

All the better for him as Isagi tasted wonderful. His dick invited a delightful pressure onto his tongue. The width of his package provided an addicting stretch around his lips and curved beautifully down his throat.

“F-fuck… Nagi please.”

Nagi remembered when watching porn, he would see the woman look the man in the eyes as she sucked him off. He wondered if that would be as effective against Isagi. Bracing himself, he slowly lowered himself more on Isagi’s length, signifying every new inch taken by a teasing suck.

Looking up, Nagi caught Isagi's lust-filled gaze, holding it as he sank lower, taking more of that glorious length into his hot, eager mouth. He sucked firmly, his tongue swirling along the thick shaft, savoring the musky flavor of Isagi's arousal. It was cute. Isagi's legs were shaking underneath Nagi’s grip.

"Mmph, fuck..." Isagi panted, his voice strained with pleasure. His hips twitched, fighting the urge to thrust up into Nagi's mouth.

Nagi could feel the heat of Isagi's skin, the pulsing of his thick vein against his tongue as he took him deeper, until his nose was pressed to the hairs at the base of his cock. He inhaled deeply, filling his lungs with Isagi's scent : not overly masculine, not particularly feminine but uniquely Isagi’s.

Holding Isagi's desperate gaze, Nagi began to bob his head, sucking Isagi's dick with increased rigor. The sounds of their activities were nothing more than wet and obscene. The shorter teen struggled to hold the other’s eye contact.

His mind was telling him to move away, to run , to do something to get out of this situation. Goosebumps had long emerged from his shoulders as did a freezing chill everytime Nagi would possessively spread his thighs apart. .

His body however relished in the ordeal. Looking into Nagi’s hypnotizing red eyes, he felt less and less like himself. His body wasn’t listening to him anymore and hadn’t been for a while. His hands remained still at his side, as if it was the last remaining sane part of him.

Nagi set a steady rhythm, taking Isagi's impressive length over and over, his head moving up and down at a scarily fast pace.He could feel the heat building between Isagi's legs, could hear his ragged breathing growing louder, more desperate.

"N-Nagi, I'm... I can't..." Isagi gasped, his fingers tangling in Nagi's hair, grip tightening as he teetered on the edge. Nagi stopped to smile as Isagi finally put his hands to use.

As if to rewards Isagi’s behaviour, Nagi doubled his efforts, sucking harder, taking Isagi as deep as he could with each bob of his head. The room was filled with the lewd sounds of Nagi's suckling and Isagi's increasingly erratic breathing. Nagi's eyes watered slightly from the effort, but he didn't stop, driven by a primal urge to taste Isagi's release, to feel him let go completely.

Luckily for him , he didn’t have to wait long.

Suddenly, Isagi's body went rigid, a strangled cry tearing from his throat. "Fuck, Nagi! I'm... I'm going to..." His words cut off into a moan as his cock pulsed and throbbed in Nagi's mouth. Nagi felt the first warm spurts of Isagi's seed hitting the back of his throat.

Nagi’s first instincts weren’t to swallow, no, he quickly popped his mouth of Isagi before tilting his head down to let the warm semen slide from the back of his throat to his mouth. Once the spend had reached his tongue, Nagi’s eyes widened. The sperm’s taste was addicting.

Nagi was a bit confused, he knew semen was supposed to taste bitter. Isagi’s however, he couldn’t get enough of. He took his time to fully swallow the other’s spend, making sure to thoroughly enjoy every bit of it in his mouth.

Isagi, still dazed from his orgasm, had his head rolled back facing Nagi’s ceiling. Isagi was quite taken back by the intensity of his orgasm. In the span of a few seconds, he had reached nirvana and fell slowly back down to earth. Since when was Nagi so good at blowjobs?

“Isagi, can you fuck me?”

Isagi's eyes jumped back into focus to see Nagi looking up at him. Throughout the entire night, Nagi had looked at him with a curious look, now he looked at Isagi as if he was the taller’s next meal. Like Isagi was nothing more than a piece of meat and Nagi was a starving beast

“I don’t think we should go this f-”

Nagi’s tail has sprung back to life, seemingly twice as energetic as before. It wrapped itself around Isagi’s erection, which had concerningly not gone down an inch even after such a climax. With the added lubrication of Nagi’s saliva, the tail had begun it’s own set of stroking, this time slower and more considerate than Nagi’s. All the word Isagi should have said were cut off by the feeling

“You’re still hard, Isagi, don’t act as if you don’t want this.” Nagi rose from his feet, his standing figure looming over Isagi like a predator does prey. Isagi was conflicted. Nagi’s eyes had now settled into a deep shade of red, not infinitely burning like before. Whatever inkling of fear he felt before now felt like a short-lived fever dream.

Without a moment's notice, Nagi had Isagi pinned on the other’s bed. Nagi’s large hands locking Isagi’s own above his head, leaving no room for Isagi to hide himself.

“Be good for me and stay still.”

Chapter Text

“Nagi, I’m telling you.” Isagi pleaded - his attempts to escape were futile. Nagi’s grip was unrelenting, leaving no room for any give. Isagi would have found it impressive - and quite hot - if his brain wasn’t spinning in circles.

“Seishirou. Call me that.” Nagi’s attention was occupied as he used his free hands to work down his pair of shorts. His words, like his grip, didn’t lend themselves for negotiation. The way each syllable rolled off his tongue had Isagi drawing into it like Nagi was an ethereal mermaid and Isagi a humble, unsuspecting sailor.

“Sei please..”

“Yoichi...” Isagi’s given name rolled off Nagi’s tongue like an unfinished thought. The word was new to Nagi’s tongue. His lips didn’t let go of the sound as if testing how it tasted, how it felt in his mouth, and how his voice sounded the word. Nagi had said the other’s first name without permission, and most definitely with intention.

Isagi was wrong. Nagi wasn’t a mermaid waiting for some sailor to entertain him, not in the slightest. Nagi was a siren, a calculating thing, luring Isagi right into his trap.

“Yoichi, please...” And Isagi was the fool for letting himself get this close.

Now naked from the waist down, Nagi leaned forward. The taller had found his position, kneeling slightly above Isagi’s crotch. His lower body was just a few inches out of sight, and his upper body pressed right against Isagi as the taller breathed heavily, the rise and fall of his chest pushing Isagi’s face against the yielding surface of the mattress.

Nagi, feeling strain in his legs, finally lowered himself onto Isagi’s crotch. Worryingly, Isagi didn't feel the expected press of Nagi's dick against his. Instead, he felt Nagi’s tail reach up... and then, a shocking warmth where Isagi's body met his – folds.

What Isagi felt was his painfully hard erection being pressed against Nagi's warm, slick folds. The sensation of Nagi's scorching heat enveloping his throbbing shaft sent a jolt through Isagi's body, making him gasp.

‘This isn’t right,’ Isagi managed to think between the fog that was now his mind. He had seen Nagi naked before and he always had a dick. Was Isagi dreaming? That would explain the tail, the eyes, and now this.

However, any thought of this encounter being dreamt up was quickly forgotten as Isagi could feel Nagi's excitement dripping down his length, coating it in glistening arousal. Fuck Nagi was so wet.

“Need you..” Nagi begged grinding his aching clit against the shorter’s length. The vibration caused by Nagi’s words travelled deep into Isagi’s chest from where they were connected. Nagi’s firm abs pressed against his face, and Nagi’s body heat spread all over him.

Isagi couldn’t see Nagi’s face from this position; he couldn’t even see where their bodies were touching down there. And with Nagi’s broad chest blocking all of the room’s lights, the only grounding feeling was Nagi’s steady heartbeat, the constant pressure of the taller’s weight against his, and the blistering heat of where they were soon to connect.

“Can I put it in?” Although Nagi was asking, Isagi knew he didn’t need an answer. Isagi couldn’t deny how his body craved to explore these uncharted waters; if anything, the rest of him was waiting for his mind to finally give in.

And give in he did.

–

Nagi’s body was changing.

Physically obvious from the predatory glow of his eyes staring back at him through Isagi’s, or the sin-black tail emerging from his lower back, or even the pulsing sex between his legs.

The feeling of his throbbing cunt against the other’s member was deliciously inviting. The memory of Isagi’s taste on his tongue was spurring him into action. The look of confusion mixed with slight fear on Isagi’s face was downright dangerous.

With ample strength, Nagi raised his waist and lined up the swollen cock with his entrance. Nagi had never done this before, he’d hardly ever watched porn either, but his body moved as if he did. His body moved as if not fully his but just moving under a vague order his mind had given it.

When Nagi felt the tip pierce his body, he didn’t feel any sort of immediate satisfaction. Instead, his body craved for more, telling him to take the inch Isagi had given him, plus an extra mile.
Leaving no time for adjustment, Nagi slammed down, taking Isagi’s entire length in one fell swoop. The weight of his body now concentrated on Isagi’s groin.

Poor Isagi, the boy could only choke out a sob as his, undoubtedly virgin, body got used to the pleasure Nagi knew he was feeling. Isagi’s eyes didn't even meet his; instead, Nagi found the other’s gaze fixed to where their two bodies connected. The look in Isagi’s eyes was distant, as if he could hardly comprehend what he was seeing.

How cute.

Nagi shifted his weight from Isagi’s groin and onto the legs that knelt on either side of Isagi’s body. Nagi knew he wasn’t exactly light. And Isagi, as small as he was, would have some trouble supporting his weight. The bed creaked slightly, and Nagi could feel Isagi’s chest rise and fall in quick succession as he let out laboured breaths.

“Sei, you’re so tight.”

Nagi let his finger run down Isagi’s torso, testing how the other’s bare skin felt. Isagi could only shudder as Nagi’s finger started at his collarbone and slowly made its way down to his hip. Nagi’s finger was burning; everywhere he touched caused an unfamiliar warmth to rise under Isagi’s skin.

Caught between the feeling of Nagi’s warm heat around him, the soft mattress dipping underneath their combined weight, and the feeling of Nagi’s smooth tail as it held him susceptible to Nagi’s blinding pleasure? Isagi could only struggle uselessly against it.

Not because he didn’t want this. Not at all. He wanted more.

“You wanna touch Yoichi?” Nagi teased, finally moving his hips in circles, giving Isagi some sweet friction that only served to fuel his aching want. Isagi, upon hearing Nagi’s question, began to nod his head.

It was embarrassing, the way he seemed to lose all his shame. Reduced to nothing but a whiny dog begging for something as small as this.

But then again, shame and rationality long since left the equation.

Rationality had ended when Isagi felt Nagi’s lips on his. It ended when Nagi’s hands explored Isagi’s body with silent curiosity. It ended when Nagi knelt between Isagi’s legs, gaze fixed on his erection. It ended when Nagi brought Isagi to a mind-breaking orgasm.

Without realizing it, Nagi’s tail had retreated behind him, and Isagi’s hands were now free to move.

At first, Isagi was unsure of what to do. Nagi’s naked form was a masterpiece to be appreciated with care, and Isagi hadn’t the least clue of how to start. Isagi wanted to explore every part of Nagi’s body. Still, the most enticing part was his glaring sex that just seemed to take him so well.

With an idea, Isagi placed one hand on Nagi’s thigh. It was firm and defined, with visible muscles: Isagi expected no less from the other.

The other hand found purchase on Nagi’s inner thigh, just an inch away from Nagi’s core. The heat of their lovemaking lured Isagi to touch, to feel the other for all he was.

Getting over any hesitation, he let his hand drift further inward, drawn by the searing heat emanating from Nagi's core. His heart pounded in his chest as his fingers approached Nagi's most intimate area, now glistening with anticipation. With a shuddering breath, Isagi’s fingers grazed against the soft, slick folds. They were petal-soft and drenched with arousal, parting willingly to his gentle touch. He stared obsessively at how, when he pressed against them, they would squish under the force. A shaky moan escaped Nagi's lips, his hips instinctively rolling forward, seeking more of Isagi's touch.

The sensation of Isagi's fingers gliding along his weeping slit sent volts of pleasure coursing through Nagi's body. Spurred on by Nagi's reaction, Isagi grew bolder. Using his thumb, he circled Nagi's sensitive clit, trying to draw out Nagi’s sounds.

“Feels.. good.”

Isagi keened at the small praise. His eyes were focused on the pretty pussy infront of him. Watching how his insides stretched around Isagi’s length and how it all disappeared inside of him.

In his peripheral vision, he could see Nagi’s expression change. His look of silent hunger had transformed into a smile. Not a genuine smile like one would see every day. No, his face warped into that of a starving beast who finally caught their prey. His mouth thinned into a too-wide grin, his eyes went from a subtle red to a glowing crimson, which, despite the bright light of the room, shone even brighter.

Isagi had never seen Nagi so... expressive. Still, he wouldn't call it a comforting sight. A low, guttural chuckle rumbled in Nagi’s chest, a sound more predator than human, sending a full-body shiver down Isagi’s body.

Suddenly, he could feel Nagi’s tail wrap around his leg. The appendage didn’t feel like flesh; it more closely resembled fluid metal. Soon enough, Isagi felt his leg get pierced by what he assumed was the tip of Nagi’s tail. Unfortunately, he wouldn’t have time to confirm as he could feel an unknown liquid slowly entering his body.

Isagi was shocked, but his body didn’t fight back. He didn’t think he was in any danger; if anything, he let himself go with what was happening. As a few seconds passed, he could feel himself slip.

Not into unconsciousness, but rather into another thing, something interesting.

The next morning, Nagi woke up to an unimpressed Chigiri standing over his bed, peering down at him.

“I can’t believe no one picked up on this,” Chigiri said, bemused as he eyed the naked teen before pinching the bridge of his nose and turning around.

“Chigiri? Why are you?” Nagi asked, moving to wrap his exposed dick with his blanket. Unfortunately, the blanket didn’t move, seemingly stuck on something else behind him

Slowly turning his head, he was met with the image of Isagi sleeping peacefully next to him. Nagi’s duvet had covered up Isagi up to his chin, and he kind of looked like a big baby. At first, Nagi was confused: Why was Isagi in his bed?

Slowly lowering the duvet off the other’s body, Nagi was greeted with the sight of Isagi’s body littered with blossomed hickeys and bite marks. Now that he thought about it, the room smelled strongly of sex.

Suddenly, memories of the last 12 hours came flooding back all at once. The feeling of starvation, Isagi showing up at his door, and…what happened after that.

“So, are you going to explain to Isagi what you just did?”

Chigiri's voice broke the silence as the redhead glanced around Nagi’s apartment. “First time I’m here and this is what happens,” he mumbled to himself.

“I don’t understand, what happened?”

“Of course you don’t.” Chigiri groaned, his friend’s obliviousness proving rather frustrating. Chigiri’s eyes quickly moved to the minifridge. Chigiri opened it and brought out a Jello packet before his eyes filled with understanding.

“You’re a succubus, you probably didn’t know, did you?”

“What?”

“It makes sense- a stupid amount of sense. I’m surprised I was the first to pick up on it.”

“I’m not… what are you saying?”

Nagi’s brain was spinning, too much information was entering at once, and he had just woken up. Chigiri turned around and looked Nagi in the eyes, a small laugh leaving his mouth. The other’s eyes still had a tint of red behind a layer of grey.

“You can always ask your parents,” Chigiri said before walking up to the now-covered Nagi. Looking over the taller’s shoulder, the blue-haired striker was still fast asleep.

Extending a hand, Chigiri brought it to Isagi’s mouth. Upon feeling the steady breadth of his friend against his palm, he let out a sigh of relief. “At least you didn’t kill him.” Chigiri slowly began dragging Isagi out of bed, trying carefully not the wake the sleeping teen, “Now help me clean him before he wakes up.”

“Yes, definitely, but you have to tell me what’s going on.”

“Sure, let’s just be quick with this.”
