the dendro archon will disapprove of this one

Summary:

A memory bubbled up to the surface. One about Tighnari, on the day that she’d last seen him.

“Um, Master?” Collei called out for him. “When will you be back?”

“Soon,” was all he answered.

Collei hasn't seen Tighnari in a week. After hearing suspicious sounds in his room one night, she rushes in to his aid - and gets more than what she bargained for. A different kind of "help" from what she initially thought.

Notes:

yes, i'm back after 2 years (if you know me). i've evolved from enstars incest to genshin age gap porn. this has been simmering in my drafts for almost a FULL YEAR, officially marking my 1-year anniversary as a tighlei shipper. most of it was finished, so i only needed to write the "aftercare" sequence, if that's what you wanna call it LOL. it was deliberately short because i felt like i'd ruin this peak ass draft if i wrote more beyond what was already there :p i hope the other ZERO tighlei fans out there enjoy this T_T

Work Text:

It’s been a week since Collei had last seen Tighnari.

A week since he’s shut himself in his quarters; a week since he delegated certain tasks to the rest of the rangers, asking them to take on his duties for a set amount of time; an entire week since anyone has caught sight of the Chief Officer.

And what a long week has it been. Collei had been diligently fulfilling each of her daily duties as a Trainee Forest Ranger, just like how she usually performs with her master around. Yet a certain emptiness created an unmistakable void in her heart ever since Tighnari had left her by herself. As much as she wanted to prove just how capable she could be, she couldn’t help but admit that her days have been getting rather lonely without the presence of her mentor. Her desire to be seen as competent, mixed with a rather silly yearning for him, created an unsavory blend of conflicting emotions within her, one that she was unable to shake off — fortunately, it didn’t hinder her from accomplishing the tasks she’s been assigned with, so her days continued like normal.

A memory bubbled up to the surface. One about Tighnari, on the day that she’d last seen him.

“Um, Master?” Collei called out for him. “When will you be back?”

“Soon,” was all he answered.

And that was it, regrettably so. Sometimes, she wished that she had said a little more before he promptly left. But there was a sense of urgency in his behavior, he only briefly looked back at her before turning away once more, finally sealing himself away in his room for who knows how long. The tasks handed over to the Forest Rangers were enough to last them weeks, but he gave no further explanation. No further context. Collei wouldn’t consider herself an intellectual like him, so his reasoning was completely lost to her. A rather upsetting fact.

Rumors have been circulating around the other Forest Rangers, and the young girl had caught wind of the gossip surrounding the absence of their head ranger. Rumors were just that: rumors. All baseless hearsays, she could briefly remember being warned by Tighnari to not believe in such talks — but it was just so tempting to listen in on the other rangers’ discussions, especially when it concerned a person she cared for.

Collei had drawn a few possible conclusions, or “high-poh-teh-sees” as her master would say. (Geez, he’s always using such difficult-sounding words; this is why his essays are so hard to read!)

One, Master Tighnari was sick, and he didn’t want to burden the others so he’s resting up on his own. The other was that he was busying himself with research, maybe tasked with an important duty from the Akademiya.

And there was another rumor, yet the topic would die down once Collei would approach those discussing it. Something related to the seasons, the month being January and all, and it had been bothering her ever since she caught wind of it. After all, the rangers would immediately attempt to steer away from the subject in a rather awkward manner, and any questions related to it would be deflected or shut down.

Strange.

On the topic of strange things, there’s been sounds coming out of Tighnari’s quarters. Whenever she passed by, it would range from mere shuffling, to full-on breathing. Heavy breathing. The odd sounds only doubled onto her concern and curiosity, to the point that a few close calls have been made, where she found herself stopping in front of his doorstep with a hand outstretched to knock. But she stopped herself in the nick of time, the stern voice of her master resonating through her mind.

Do not, under any circumstances, disturb me or come near my quarters at any time.

Collei knew she wouldn’t be able to bear the consequences that came with disobeying his orders, yet as each day passed, her anxiety only increased tenfold. Just like the sounds that came out of his room. It was impossible not to be worried about someone that she deemed so important to her, leaving her completely torn between two difficult choices. To obey or disobey.

It was a particularly tranquil evening in Gandharva Ville, the forest having quieted down as humans and animals alike were settling into a peaceful respite. After making one last round, ensuring that everything was in order, Collei had begun to walk towards her room — she’d been eager to get some rest, maybe continue that light novel she picked up recently until she could fall asleep.

She knew that on her way over, she would be able to pass by Tighnari’s room. Her footsteps slowed as she eventually approached his door, keeping her ears open for anything unusual that she might hear once she got close enough.

Thump.

Without much thought, her body had begun to move closer to the surface of the door. Another set of shuffling, accompanied by more thumps… until all sounds came at a standstill. It took an awfully long pause for Collei to pick up anything else beyond that, and if anyone were around at this time, she was sure they’d be rather concerned as to why she was just standing in front of her mentor’s doorstep like some creep.

Breathing, followed by a grunt that sounded rather pained. His grunts, making him sound like a wounded animal. Her eyes widened at the suddenness, but she continued to listen intently. It was taking everything in her to not barge in out of pure worry for him, balling her hands into a closed fist as she attempted to stay still.

Collei…”

That was new. That voice, which she was absolutely certain belonged to Tighnari, called out for her name. Strained, almost choked, accompanied by heavy breathing and– were those growls she was hearing?

Collei… Collei…

“Master!” Even if she prayed to all Seven Archons and begged for their forgiveness, it might not constitute for the wrath that Tighnari might unleash upon her for going against his orders, but she was inevitably rushing inside his room without a second thought. It was as if Collei’s body had a mind of its own, a wave of unimaginable distress washing upon her after an entire week of enduring his absence. It was almost agonizing to ignore his gut-wrenching cries for her name, and it was the sworn duty of a Forest Ranger to help those in need — she simply couldn’t bear letting her beloved mentor suffer in solitude.

Collei’s eyes eventually fell upon what looked like Tighnari’s curled up figure in the middle of his uncharacteristically messy bed. Clothes and pillows were strewn across his room haphazardly, which shocked her when taking his clean freak personality into account.

“Collei, I told you not to come in…”

Her master’s attempt at reprimanding her made her wince, yet there was an obvious strain in his voice that reduced the severity of his tone. She only had the light from the doorway to illuminate the room, barely able to make out his seemingly writhing figure in his bed.

“I-I’m sorry, Master! But you sounded like you’re in pain, so…” She began to approach his bed, shutting the door behind her. However, she was unable to take any more steps towards him before a low growl came from Tighnari that made her stop dead in her tracks.

“Don’t come near me,” he said. “I could hear you, outside my bedroom… You had me practically praying that you’d listen to what I said—”

He winced, essentially cutting himself off. It was difficult to make him out now that his room was shrouded in darkness, save for the moonlight peeking through his windows. Still, Collei’s body urged her to get closer to his writhing figure, taking small reluctant steps towards his bed.

“But I want to help you,” she responded, voice laced with worry. “You’re in pain, Master! You’re always taking care of me, so I should take care of you too. Please?”

Tighnari remained silent. Unsettlingly so. Eventually, she was in close proximity to his bed that allowed her to peer over his curled up form. Her expression was nothing short of apprehension mixed with genuine care, hesitantly outstretching an arm towards him in hopes to check for his condition, just like how he usually would.

“Master?”

A hand — Tighnari’s hand — reached out from the nest of pillows and blankets, her wrist caught in a vice grip. Before she could utter another word, Collei could feel herself getting pulled towards the bed in a rough fashion. A soft thud resonated through the pitch black room, and she found herself laying down amidst the messy pile that drowned her in the natural scent of her mentor. It was heavy, his essence threatening to consume her whole.

“Help me, you say…”

And from that dangerous glint in Tighnari’s eyes from above, it looks like he wanted to devour her as well. With her eyes now fully adjusted to the darkness, the carnal hunger in his eyes was unmistakable. Collei wasn’t merely gazing into those familiar, beautiful gradient eyes of his, ones that captured the gentle spirit of the forest — instead, she felt like a cornered little lamb, fearfully looking into the eyes of its ravenous predator.

Hunger and desperation. A terrifying mix, but it instilled another kind of feeling within her.

It was hard for her not to gulp under the sheer pressure of his intense gaze. Even so, she could still feel a hint of hesitance radiating from his words.

“I thought I didn’t need to warn you a second time for you to listen,” Tighnari muttered under his breath, sounding rather annoyed, at least in Collei’s eyes. “You just had to barge in and get yourself into this mess… You shouldn’t have to see me like this, I’m your teacher—”

“You were calling for my name, right?” Collei interjected, but the plentiful lessons on how she had to wait her turn before speaking instantly came rushing back to her, which she quickly tried to rectify lest she were lectured once more. “Ah, I-I mean… Sorry, Master, but I really couldn’t help but come to your aid when I heard you saying my name. I didn’t mean to, I swear!”

What she didn’t expect was the sigh coming out of her mentor’s lips. A sigh, nothing more. No reprimanding, no nothing. Just that, a soft exhale.

“Look, Collei, I… I knew you were listening just outside.” The uncertainty in his voice was evident, but he let out another heavy sigh before continuing. “I knew it was you from your walking pattern. No one else in Gandharva Ville has footsteps as quiet as yours, but I could still pick up on it. And with the thought of you on my mind, I just…”

It was an uncommon occurrence for the Chief Officer of Avidya Forest to be so worked up, and Collei thought it was her thing to stumble on her words like that. Her ever-so composed teacher was on the brink of losing it, a novel yet intriguing sight for the curious girl. For some reason, she felt the urge to reach out and brush his hair away from his face, just so she can admire him further without obstructions. The room was partially bathed in the moonlight, creating just the right ambiance — the subtlety allowed her the perfect view of her master’s disheveled appearance. The way his chest heaved with every exhale, his half-lidded eyes glossing over her figure (so much that she’s squirming), his sharp canines glinting in the dark with his mouth slightly ajar—

Oh, Archons. Collei couldn’t even begin to comprehend the swarm of butterflies swirling around in her tummy.

“You want to help, right?”

“Yes,” she blurted almost immediately. “Yes, Master. Let me help you, please.”

“Then… forgive me for what I’m about to do.”

All Collei could remember was Tighnari closing in on her. Followed by a pair of lips against hers, soft and pillowy. Hands began to wander, clothing rustling, skin pressed against skin; all she could think about is how hungrily her mentor kissed her. All at once, she could feel his throbbing need for her.

A need that she also shared, thus wanted to return tenfold. Her lack of proper knowledge on her master’s constitution made his actions confusing, but she wasn’t that stupid. Those light novels weren’t just to expand her vocabulary, no, they serve a more… vulgar purpose. Scenarios that she’s read about men ravaging their partners in a fit of passion, shedding their reservations (and their clothing, usually) to engage in indecent acts for various reasons: love, hate, humans would find a way to fulfill their lewdest desires.

And how perverted she was for thinking of her mentor, the man who took her in and raised her as his own, as she read these scenes in the dead of night. With her hand down her panties, fingers rubbing over her folds to chase that high, yet never being quite there.

“Master…” The same name she mewled for all those nights, finally slipping out of her lips as she attempted to kiss him back. Her hands tried to reach out, feel him up through that black tight-fitting shirt of his, but Tighnari only pinned her wrists back onto the bed, one hand keeping her locked in place.

“Shh, you’re getting way ahead of yourself,” he murmured against her lips. “Be good for me, Collei. You can do that, right?”

The younger girl nodded frantically, but Tighnari only clicked his tongue.

“Your words, Collei. Use them.”

“Y-Yes,” she mumbled.

“Louder. Yes what?”

“Yes, Master…” Her voice was trembling. “I’ll be good, I-I promise… I won’t disappoint you.

“Good girl.” The sultriness in his tone almost drove her over the edge. “Archons, I can’t hold back anymore. I need you.”

Their mouths connected once more, losing themselves in a passionate makeout session. Tighnari’s tongue was able to slip into her mouth, his desperate movements really making her feel as if he wanted to eat her. Collei could feel him pressing his knee in between her shaky legs, the pressure against her clothed core causing her to let out small whimpers against his lips. Oh, how she longed to feel up his body, her lust was practically consuming her — so close, yet so far — but being restrained was something she could endure for the time being. She was supposed to be helping her master get through… whatever this is, she had no idea, but it felt so good.

Tighnari was the first to pull away, a trail of saliva connecting their lips for a split second before it broke. Collei wanted to chase after him, yet she could only muster a whine once he started nibbling on her neck, his sharp canines grazing against her sensitive skin. With his hand preoccupied by keeping her pinned down, his other hand began to fumble with her flimsy panties, slipping inside the fabric with no resistance at all. His nimble fingers pressed against her sopping folds, letting out a soft growl against her neck.

“...Wet,” he muttered. “So needy.”

Collei almost wanted to apologize for being too excitable, but a sharp gasp escaped her mouth before she could utter a word. His teeth dug into her neck, earning a series of pained sounds coming from the girl. At the same time, Tighnari’s fingers started rubbing her clit in steady circular motions, creating an addictive cocktail of pain and pleasure that coursed through her veins. Blood trickled down her neck, painting the sheets crimson as her hips bucked up into her master’s hands.

Tighnari used his knee to force her legs apart, allowing his fingers better access to her dripping hole. He shoved two inside of her in rapid succession, the lubrication allowing for easy entrance into her cunt, eliciting loud moans from his student. His larger hands allowed him to reach deeper within her, hitting all of those spots she couldn’t during those times she played with herself, feeling so stretched already with only two fingers inside of her.

She was going to cum at this rate, with how fast his fingers pumped in and out of her, with the bites that he littered on her neck. She was close, so close—!

“I can’t take it anymore—” All sensations stopped, and the shuffling of clothing could be heard. “—Need to be inside.”

Tighnari grabbed her thighs and pushed them back against her chest, quickly mounting her as he placed her legs on his shoulder. Collei watched him in complete awe, eyes trailing downwards to watch her master pump himself, aligning himself with her entrance. It took her a second to register the fingers being placed inside of her mouth, the same ones that he used to fuck her, but any protest was instantly drowned out by a yelp once he finally put his cock inside.

Big, that was her first thought. Even after being fingered, it still wasn’t enough to prepare her for the first thrust. Any moan that escaped her mouth only made him shove his fingers deeper down her throat in response, taking his sweet time bottoming out inside of her, letting her feel every single inch of his pulsating cock.

“Shh, quiet,” Tighnari grunted, his composure dwindling by the minute. “D-Don’t want the other rangers to know I’m, ah, fucking my student—”

Full, that was her next thought. Collei could only shudder at how deep she was taking him, their position making it easier for him to bury his cock to the absolute hilt. She felt the tip pressing against her cervix, making her feel dizzy — especially with the delicious sight of her master right before her eyes. His eyes were screwed shut in pleasure, panting heavily as if he wanted to maintain self-control, but the tightness of her cunt was driving him wild with abandon.

“Tight, so tight,” he mumbled incoherently. “Collei— god, you’re so tight—”

Oh, he was definitely losing it. Her master was never the type to delay a single second, and without warning, he started to thrust his hips forward. In and out, Tighnari wasn’t giving Collei a single second to adjust, his mind solely focused on fucking himself deep inside her. His cock hit all of those perfect spots that turned her brain into mush, with only the thought of him and his cock resonating in her mind. And how badly she wanted to cum, but most importantly, to have him cum, deep inside.

Please please please, she wanted to mewl out. Yet with her mouth stuffed with his fingers, Collei could only let out choked gasps and moans against them. Tighnari’s hips made lewd slapping sounds against her skin, accompanied by the sound of his unabashed moans of ecstasy as he buried himself deep inside again and again and again—

Something was pushing up against her folds. Collei frantically whipped her head at the strange feeling, but only got her head forcibly pushed back onto the pillows by the fingers lodged in her mouth.

“It’s fine, Collei,” Tighnari groaned, each thrust inside of her eliciting sharp inhales from him. “Y-You’re gonna love it, take it— just be good and take it…”

The next set of events that unfolded all happened too quickly, but discomfort started to bloom in her cunt—something stretching her out, more than she can take. Tighnari was pushing it into her, forcing her to take the painful stretch of his… What even was that?

No, no, she almost wanted to scream— and she was, she was crying out into his fingers. But they only turned into garbled sobs, the terrifying blend of pleasurable and stinging sensations amplifying the fire burning in her tummy.

“Collei, g-gonna cum…” he grunted, unable to string together more structured sentences amidst his thrusts. “Inside— gonna cum inside, Collei, I—”

Collei had little time to prepare for the load that came after he uttered those words, feeling him bury himself to the hilt before he came undone. Her pussy clamped around his cock, her moans choked from the fingers in her mouth — it didn’t take long for her to cum along with him. Tighnari’s cock was directly nestled against her cervix, his semen filling up her womb to the very brim. Along with his cum, that certain something was completely lodged inside of her, keeping his cock locked in place. Her tight hole took it in completely, and no amount of squirming could ease it out of her, essentially keeping his load from seeping out.

A stream of tears began to run down her flushed face as soon as Tighnari removed his fingers from her mouth. Whether they were tears of pleasure or pain wasn’t something she knew. But if there was one thing she knew for certain, she’d never felt this stuffed in her life.

“M-Master, I— what’s that… inside me?” she asked breathlessly.

“Ah, well…” Tighnari panted heavily, his tone uncharacteristically sheepish. “My knot, Collei… I knotted you. Looks like we’ll have to stay like this for a while.”

“You can’t pull it out?” Collei asked through her tears, although the question felt rather stupid, seeing how his knot stuffed her entirely.

“I can’t, Collei. We’ll have to wait a little. If we rush it, it’ll hurt. A lot. Trust me, I don’t want to harm you.” Tighnari brought a hand to her face, swiping her tears away with his thumb. “You already went through the trouble of… well, ‘helping’ me, I suppose. You’ve been a big help, is what I mean. It’ll pop out on its own, don’t worry. Just stay here for a bit, alright?”

Collei’s sniffles would eventually quiet down, and the throbbing ache in her pussy would begin to dull and fade away. A small nod was all she could muster,

It wouldn’t hurt to stay in his quarters for a while, given that she’s stuck here regardless. No, not stuck — it wasn’t like he was holding her captive. Besides, she liked it here. Everything smelled just like him.

Just like that, she’d realized just how much she had missed her teacher.

“Um… I missed you a lot, master.” Collei mumbled, half-hoping that Tighnari wouldn’t hear it.

“I know.” Tighnari smiled.
