Dammit, why does it have to be raining? Iruka thought to himself as he glided through the forest. He was on his way back from a mission, a relatively short and simple one to his relief. He thought he’d be able to make it back to Konoha by nightfall until he saw dark clouds collecting in the sky. Not that he couldn’t travel in the rain but he’d prefer not to if he could help it.
He stuck to the larger trees with more shade, hoping that they would shield him from most of the rain but it could only do so much as he proceeded to get soaked.
Please let me find shelter , he prayed internally as he made it to a road. Going further down the path he slowed down as he came across a sign:
Kubisaki Pass
“Kubisaki… that sounds familiar,” Iruka didn’t have time to think too much of it as thunderstruck, startling him a little. The sky lit up for a moment, illuminating a castle in the distance. Weird , he thought as there weren’t any known castles in the area but he ran towards the structure regardless to get out of the rain.
The castle wasn’t too big, he noted as went up the steps, still trying to figure out if it was a notable landmark. Once he made it to the top, the doors opened as he approached them which he found disturbing but ignored it regardless and stepped inside.
“Hello?” He called out. “Please excuse me, I want to take shelter from the rain.”
There wasn’t any response but the lights were on, letting him believe that he wasn’t alone.
Looking out the window, the rain didn’t seem to be stopping any time soon leaving him plenty of time to wander about. Iruka walked cautiously through one of the hallways, eyeing the paintings and armored statues at every corner. The more he thought of it, the more familiar they seemed though he couldn’t place it.
“Devour,” a voice echoed.
Iruka stopped in his tracks. The voice was quiet but it was there, almost like a light breeze. He closed his eyes, trying to hear it again.
“Devour.”
There it was again. He felt the floor vibrate slightly at the rumble and turned around, taking out his kunai in a fighting stance.
“Who’s there?” He called out and the vibrating stopped along with the whispers. He wasn’t convinced that it was over, however, and returned to the main hall, kunai in hand.
As he was passing through familiar hallways, he noticed that the walls seemed to have changed, their texture looking more bumpy and rough to the touch. The placement of the armored statues also changed to sporadically stand in the middle of the hall.
Once he made it back to the front door, he debated on leaving, feeling a spike of something sinister shoot up his spine. He took a step towards the exit but giant teeth suddenly clamped down in front of it, blocking the way.
Iruka jumped back and threw a kunai with a paper bomb tied to it at the teeth but they were impenetrable.
“Dammit,” he seethed, trying to quickly think of a way out. Turning around, he looked for another way out, possibly through the windows, but was stopped by one of the armored statues now moving right in front of him.
“I am the Castle,” it said, catching him off guard. “ And by order of Gosa Kunisaki: all who enter shall be devoured.”
Kubisaki Castle , Iruka’s eyes widened. That’s how he knew of it. He scolded himself for not realizing it sooner, especially as he was in the territory of the old Land of Necks. He’s heard of the rumors before in passing of a haunted castle where those who approached it mysteriously disappeared.
Iruka tried to quickly think of a plan of attack to buy time to escape but was interrupted by the mirroring cabinets on the sides of the hall opening all of a sudden. Out of them shot out thick, warped tentacles. Iruka’s eyes widened at the sight, what the hell did I get myself into?
The tentacles were fast, darting straight towards him. Iruka jumped in a zigzag fashion, dodging a majority of them. The rest, he sliced with his kunai. The more he got rid of, though, the more would appear, seemingly getting faster with each one.
“Are they multiplying? ” Iruka asked himself, his arm slowly growing tired from all of the swinging. He bolted towards the stairs, thinking that would give him a height advantage but the tentacles followed him wherever he went. Every direction he turned to seemed to be shut off by another set of teeth as well, cornering him at the top of the steps. “Shit,” he cursed, feeling the ground beneath him start to feel softer.
Iruka was too distracted by the rest of his surroundings he failed to notice the tentacles clustering behind him, eventually making their move to wrap themselves around his ankles.
“Shit!” Iruka cursed again as he was promptly lifted above the ground upside down. He tried cutting off the offending tendrils but was stopped by others gripping his arms and twisting them slightly, causing him to drop his kunai.
Iruka was now defenseless and unable to move, horrified to find more tentacles surrounding him by the minute.
This is my end , Iruka thought. I’m gonna die.
Only that wasn’t what happened. Instead, Iruka felt the temperature around him start to rise as beads of sweat trailed down his face. His breathing became shallower and jagged as the tentacles made attempts to tighten their hold.
What’s happening to me? His clothes felt too tight and hot, almost like they were burning him. He wanted them off. Iruka wriggled around uncomfortably, trying to find some kind of cooling relief.
It was then he realized what was going on. The tentacles were releasing some kind of aphrodisiac, and he was absorbing all of it.
The struggling became more desperate now, Iruka trying to hold on to what little sanity he had left to escape but he already knew it was too late, he had already succumbed to the heat.
The tentacles seemed to have recognized that he was already too far gone as the tight grip on his wrists let go, now moving on to focus on removing his clothes. The heat collecting on his chest felt lighter as the tentacles delicately unzipped his flak jacket and slipped it off, his shirt soon following. Iruka let out a sigh of relief as his warm skin was exposed to the cool air. Though it wasn’t enough as his pants felt tighter and more uncomfortable to wear in contrast.
“Take them off please,” he whispered, to which they did, rather quickly in fact. Soon he heard the soft noises of his shoes falling onto the floor as well as the rest of his clothing. Iruka wanted to cry out as his erection was eventually released, though he still felt oh so warm.
“Touch me,” he begged the tentacles, jutting out his hips. There seemed to be a hesitation until he felt one wrap around his cock, making him moan loudly. “Fuck, that feels so good,” he gasped, the heat cooling down slightly. The tentacle was wet with some kind of slick and Iruka shivered as it moved up and down at a steady pace, leaving behind a sticky residue.
“Faster,” he said, feeling hot again, his cheeks a dusted red. The tentacle followed his request, now moving at a quicker pace making Iruka choke on his moans as he neared his release, his cock leaking precum.
Pathetic, he thought to himself. It’s barely touching you and you’re already this close? He ignored it as the tentacle tightened its grip on his dick, squeezing it with its burning surface. Iruka was caught off guard and came instantly with a surprised cry. The tentacle didn’t stop, however, slowing down only to milk his orgasm and lightly play with his tip.
Iruka shut his eyes in embarrassment, he felt like such a virgin, though he knew this wasn’t the end. The warmth was still there, suffocating him and leaving him thirsty for more. And in that moment of euphoria, he felt it go away for just a moment. He wanted— no, needed that feeling again.
Iruka opened his eyes, and for a split second saw a flash of silver. His eyes widened, was he hallucinating? It was a plausible assumption to make due to the effects of the aphrodisiac but there was no way he would appear, right?
“Iruka.”
That was his voice. Iruka turned his head and there he was: Kakashi Hatake.
“Kakashi,” he said softly, feeling himself heat up at the name. It was no secret that he was attracted to the Jounin, and the thought of Kakashi seeing him like this: lewd overcome with lust, even if it was just an illusion, was overwhelming. “Will you help me?”
“I think I’ll just watch for now,” Kakashi smiled from behind the mask. “You seem to have it covered.”
Before Iruka could respond, another tentacle began prodding at his entrance, slowly making its way inside, rather easily with its slicked-up exterior. Iruka clenched his teeth in pain at the insertion but it morphed into a sigh of pleasure once his muscles relaxed around it. Its girth expanded the deeper it went inside, making Iruka open his mouth in a soundless whine. He was unable to do anything but push through the initial burning sensation as it convulsed, making itself comfortable. The feeling was unlike anything he’s ever experienced before, which was to be expected he guessed, as he’s never taken a tentacle up his ass before. The sentient nature of it was so bizarre to him as every touch, every brush against his inner walls felt calculated and purposeful, driving him insane.
“Ah,” his head fell back, taken by its slow and deliberate touches inside him. He spread his legs as much as he could to let more of the tentacle in along with its delicious heat. Soon it began lazily thrusting in and out of him, Iruka letting out little short breaths every time he felt it bottom out.
Iruka looked weakly at Kakashi through hooded eyes, who only stared back at him, an unreadable expression on his face. He wondered what the real Kakashi would say if he were here; would he find the sight arousing or would he be disgusted? Iruka didn’t know which he’d prefer but revelled under his imagination’s watchful gaze.
The tentacle seemed to notice his distraction. Displeased with the lack of attention, it propelled a particularly hard thrust, making Iruka gasp. “Fuck, that’s too much,” he squirmed in its grasp to which another tentacle wrapped itself around his waist to keep him in place. The tentacle inside him then proceeded to pull out with Iruka groaning at the loss. It pulled all the way out before plunging deep inside him making Iruka scream in both pleasure and pain. It felt like he was punched in the gut but in the most sexual way. The tentacle repeated the action over and over again, fucking into him until he was garbling mess nearly unable to think.
His insides felt like they were being bruised at the aggressiveness but he itched for more. The heat surrounding him felt thicker and more addicting with each rough thrust feeling more heavenly than the next. Iruka’s toes flexed and he stretched his neck out, skin burning with desire and body trembling with need.
“Shit, shit, shit,” he cursed, hating but loving how pleasurable it felt being used like a ragdoll. His hands flew to his face, pinching at his flushed cheeks and holding onto the loose strands of hair not held back by his hitai-ate. He was looking for some kind of distraction to take away from the overwhelming sensation of being completely full but couldn’t. His heartbeat rang in his head, clouded by lust. Each thrust of the tentacle was another metaphorical kick to his stomach and he loved every second of it. Iruka couldn’t tell at this point if it was aphrodisiac talking but regardless, he wanted more moremore .
“Devour,” he heard the voice from before echo all around him and he nodded profusely.
“Yes, devour me, please,” he begged, unsure of what he was even saying himself.
The tentacle then aimed for his prostate and slammed into it, making Iruka freeze as his eyes rolled back. “Fuckkk,” he drew out the syllables. If it weren’t for the tentacles holding him up he’d for sure collapse and melt. The sweltering heat felt almost unbearable now.
Other tentacles seemed to take his unresponsiveness as an invitation as one made its way up and around his torso, kissing his skin and toying with his nipples, making Iruka shiver at the touch. Another introduced itself into Iruka’s mouth, initially getting him to choke on the intrusion. It was sticky and wet, Iruka nearly gagged as his tongue was forced to taste it: salty and bitter. Though eventually, he wrapped his lips around it in want, licking and caressing the warm, rough surface of the tendril.
Iruka’s vision blurred with unshed tears as he was being stuffed from all ends with almost no mercy. Not to mention the tentacle still stroking his painfully erect dick. In the corner of his view, he saw Kakashi, still unmoving. Iruka wanted to cry out to him but for what? For help? For pleasure? He was sure he looked pathetic right now, even if Kakashi was just a figment of his delusional state of mind. Here he was, a shinobi of Konoha, being absolutely annihilated by what essentially was a castle . He wanted to laugh at the absurdity but instead gagged on the tendril still in his mouth pushing itself in further.
“You look so beautiful like this, Iruka,” he heard Kakashi say and he smiled. He imagined that it was Kakashi’s cock filling him up, Kakashi’s erection that he was choking on. It made the experience all the sweeter as he could see Kakashi right there , even if he wasn’t real. Iruka moaned around the tentacle in his mouth, sucking obediently. It almost made him forget about the one fucking him into oblivion from behind.
He didn’t even remember when the tentacles brought him closer to the ground but felt something like a hand pull him back by his ponytail. He envisioned Kakashi’s gloved hand being the one removing his hitai-ate and hair tie, freeing his brown locks. His eyes fluttered closed in pure bliss as he pictured that same hand touching his hot body, cooling it with the tips of its fingers.
“Kakashi,” he tried moaning, but it came out as meaningless gibberish instead.
“You should see yourself,” Kakashi whispered into his ear to which Iruka tried shaking his head. This was too humiliating, too shameful. “You love this, don’t you?” The tears began to pour over as Iruka wanted to deny it. Kakashi was wrong, but he wasn’t.
His muffled cries seemed to have stimulated the tentacle enough as the one in his mouth started vibrating violently before spurts of a thick substance released down his throat. Iruka pulled his lips off of it with a wet pop, gasping and gagging as he tried swallowing the fluid.
“Admit it, Iruka, you love this.”
You’re wrong , he wanted to say but what came out instead was “I want more.” He could only imagine how promiscuous he must’ve looked as he said it: his cheeks flushed, lips red and swollen with trails of spit and cum at the corners.
He heard what sounded like an amused chuckle come from Kakashi as the tentacles, at his request, flipped him so that he was on the ground on his knees. Iruka nearly purred at the cold sensation and wanted to lay on the floor but wasn’t allowed to by his restrictions. The tentacle previously fucking him stopped its movements and so did the ones fondling his chest and his now neglected erection. Iruka whined at the lack of touch and tried rocking against the tentacle still inside him though it didn’t help much.
“Please,” he sobbed in frustration. “Please move— ah!” Iruka let out a strangled moan as another tentacle was attempting to push in alongside the already present one. “What… what are you doing?!” He asked hysterically.
There was no answer, not even from Kakashi. He felt the tip of the second tentacle finally push its way inside and he felt his soul leave his body. He was going to die.
“I don’t know if I can do this,” he protested frantically. “It won’t fit, I’m gonna break, please— ” more than the tip started sinking in, inch by inch, and Iruka felt as though his body was going to burst.
“Kakashi,” he tried again. “Kakashi help me!”
“Are you sure that’s what you want?” Kakashi asked sardonically. “You were begging for more just a minute ago.”
The second tentacle was now fully inside him, stretching him wider than he thought was possible. Iruka felt lightheaded and didn’t dare risk moving else the tentacles would rip him a new asshole.
“Kakashi,” his voice was quiet and his eyes were blown out wide, staring up at the ceiling in shock. “It’s inside me, oh fuck, they’re both inside me…” he thought he was going crazy.
“See, you can take it,” Kakashi encouraged but Iruka didn’t hear him, trying desperately to stay still as the tentacles ran against his insides. His knuckles were turning white while the rest of his body went red. Iruka felt like he would collapse and die at any second but he found himself horrified at the fact that he didn’t even care.
After seconds that felt like an eternity, finally, the tentacles started moving. Iruka let out a breath he didn’t even realize he was holding as both of them moved in interchanging thrusts.
In, out, in, out. A steady repeating pattern. It hurt and felt uncomfortable the first few times as his tight passage wasn’t properly prepared for the large insertions but it soon was replaced with feelings of pleasure as he got used to it.
Iruka arched his back, grunts and breathy moans escaping his lips. He didn’t even know which tentacle to concentrate on as they rammed into him, the pace getting quicker. He didn’t think he was going to last if they continued. At least the heat from his body felt like it was cooling down.
“You look comfortable there, Iruka,” Kakashi noted, his face now right next to his. Iruka could only nod as whenever he tried speaking it’d come out as garbled moans. “So pathetic,” Kakashi continued, his visible eye narrowing. Iruka stared into it and saw traces of lust. Despite Kakashi’s harsh words, there was no denying that the Jounin was into what he saw.
Iruka wanted to kiss him and almost did until the tentacles aimed for his prostate and slammed right into it simultaneously. Iruka forgot how to breathe as he doubled over and moaned in ecstasy.
Kakashi pulled his head up by his hair. “Don’t look down, let me see you.”
Iruka couldn’t think about why Kakashi at that moment felt so real . Either way, he didn’t care as the tentacles kept abusing his prostate, hitting it harder and harder. Iruka felt elated and didn’t know where to look, what to think, all he could do was feel how full he was.
“Kakashi,” he moaned in his face. “Kakashi, Kakashi, Kakashi,” he repeated the name like a mantra. He felt cold hands wipe his tears and he leaned into the touch.
“How do you feel, Iruka?”
“Hot…” was all he could say. He couldn’t describe how overwhelmed he felt by everything: the thick tendrils, the heat, Kakashi.
The tentacles were mercilessly still going at full force until Iruka felt them trembling inside him. His eyes shot open and he gripped onto Kakashi’s shoulders, frantic. “They’re gonna… they’re gonna—“ he couldn’t finish his sentence as they came at the same time. Searing hot cum flooded his ass and Iruka nearly passed out as it didn’t appear to be stopping.
The pressure from the tentacles’ orgasm seemed to be Iruka’s breaking point with him cumming soon after. He felt his legs wobble and the rest of his body shiver as he finally reached his release, letting out a mangled cry. After that, Iruka didn’t think he could hold himself up any longer, his limbs giving in as he dropped to the cum-stained floor.
He doesn’t remember when the tentacles pulled out, or when the heat began subsiding. But here he was now, used and discarded on the floor. The ground's surface was cold to the touch and Iruka sighed, wanting to sleep. But something in him knew that they weren’t done with him yet. The next thing he knew, Kakashi was in his line of sight, crouching down right next to him.
“It seems like they’ve finished having their way with you,” Kakashi mused, brushing a strand of Iruka’s sweaty hair out of his face. “Though, I’m afraid I seem to have a problem I need help with as well.”
Iruka wasn’t able to process what it was exactly Kakashi was asking of him, but regardless, he let Kakashi pick him up and place his limp naked body on his lap.
“This is okay, right?” Kakashi asked, nudging his chin up to make eye contact. Iruka was in a daze but nodded. Kakashi seemed to visibly relax at that and proceeded to focus on his pants, taking out his cock and placing it against Iruka’s entrance, still leaking and wet from the tentacles.
Iruka leaned forward onto Kakashi’s chest, shuddering as he felt it easily push inside him. He was so sensitive it nearly hurt but was too tired to complain, only able to quietly pant as Kakashi did light thrusts.
“Didn’t know you were so easy, Iruka,” Kakashi whispered harshly into his ear. “First you get fucked by tentacles now me? And you’re supposed to be guiding the future shinobi of Konoha.”
“You’re wrong,” Iruka could only breathlessly say back. He wasn’t easy. He wasn’t a slut. It’s the aphrodisiac , he told himself.
“You like this, right?” Iruka didn’t answer. “Right?” Kakashi asked, sounding more desperate, pulling his head back by his hair.
“Y-yes…” Iruka moaned weakly, the rough movement causing him to clench his ass around Kakashi’s cock, making him groan.
Kakashi then became more gentle, running his hands up and down his back. He kissed Iruka’s cheek from behind his mask before whispering into his ear, “let go, Iruka, let me take care of you.”
Iruka didn’t feel his dry orgasm or any more of Kakashi’s movements. He was so tired and felt so absolutely spent it took up all his energy just to keep his eyes open. Darkness started to overtake his vision as he passed out. His last thought was:
Why did Kakashi feel so real?
Iruka was awoken by a nudge to his side. Opening his eyes, he was nearly blinded by sunlight.
“Agh!” He cringed, bringing his hand up to his face to shield the light away.
“So you’re awake,” a voice said. Iruka turned to see a familiar Jounin crouched down beside him.
“Kakashi…”
“I happened to be on my way back from a mission when I found you unconscious.”
Iruka sat up suddenly, wincing slightly at a sharp pain in his lower back. “Outside?” He asked.
Kakashi paused, eyeing him carefully. He seemed to be unsure of something but answered slowly. “Yes, where else?”
“There was a castle…” Iruka replied, trailing off, he looked around at his surroundings, wondering how the hell he got out of it. But there was nothing there. Iruka blinked, did he imagine it? His memory felt blurry but vaguely he started to remember what happened the night before. Face flushing, he quickly looked at Kakashi, who appeared to be avoiding eye contact. Feelings of humiliation took over as dread pooled in his stomach. Kakashi knew, didn’t he…
“Kakashi–” he was cut off by said man clapping a hand on his back, changing the subject.
“You must be exhausted, Iruka-Sensei. Let me take you home,” his face was void of anything other than genuine altruism and for a moment, Iruka forgot about his embarrassment and shame. He agreed reluctantly but found that he was unable to get up. Kakashi noticed his struggle, looking at him with a guilty expression before offering to give him a piggyback ride. “Don’t worry about it, let me help you,” he reassured him.
Iruka felt mortified once he was pressed against the other’s warm back, how could he ever face Kakashi after fantasizing about him like that? He was relieved that they were going back to Konoha and this mission could be long forgotten along with the castle.
Kakashi on the other hand couldn’t find the guts within him to tell Iruka the truth: that he was actually worried when Iruka didn’t return and went out looking for him, only to be trapped under the aphrodisiac as well. He felt guilt eating away at him for not doing anything and just watched as Iruka was being taken by that thing . It only worsened when everything that he did couldn’t just be dismissed as effects by the aphrodisiac, a part of him wanted to do those things, the aphrodisiac just acted as an excuse to not show any kind of restraint.
He was glad Iruka didn’t question it further, hoping he would dismiss it as a dream, he made sure to clean him up after they were done and brought him outside, away from any future harm. That didn’t erase what happened, though. Kakashi felt ashamed of himself, especially for not regretting what he did. But now that it was over, he could take him back to Konoha, where he could act as if nothing happened.
