——————————————————
A sigh escaped the lips of the captain of the crux, the evening sun feeling uncomfortably hot on her neck as she stared out at the ocean from the back of the boat.
They had been sailing for days now, and were well on their way to Inazuma to deliver more stock and whatever it was that was necessary.
Beidou could hear her crew start to settle down as they anchored for the night, the sky was starting to turn the beautiful shades of pink and orange that the captain had come to appreciate so much.
Her limbs felt sore from the day as she sat down on the ships floor, resting her exhausted head against the railing; she finally lets herself relax. Far away from the prying eyes of the crew she commanded.
She stayed that way until the sky turned a deep blue, almost black in colour, devoid of the moon that she so desperately yearned to see. Finally; after gathering her wits the captain got up from her knees.
-Only to be immediately forced to support herself with the railings (her legs had fallen asleep).
With a sigh, Beidou turned on her heel, and was on her way to go freshen up and head to bed; only to briskly turn back when she heard a loud splash nearby.
Thankfully, the captain was no fool, and she knew the meaning behind those seemingly normal sounds.
A mermaid must be lurking nearby.
That guess was only solidified into a cruel reality when Beidou saw a tail splash near the right side of the ship.
The now concerned captain ran back to where the entire crew was situated, warning them about the up and coming attack. And she was just in time, as well.
The crew quickly covered their ears the moment that they saw a pale form land in the middle of the ship. Beidou quickly instructed them to also shut their eyes as the mermaid approached, her mouth open in song.
Beidou shut her own eyes tight, covering her ears furiously so as to not get mesmerized by the mermaid. After all; she told herself that she still had a ship to sail and a crew to command.
The captain kept her eyes tightly shut until she felt soft but strong arms wrap around her waist, which were quickly pulling her to the side of the ship and into the deep, cold waters below.
Beidou felt the crews eyes bare into her as she was pushed over the edge and dragged under the surface of the water in a matter of mere seconds.
The last thing she had heard in her shocked state were the crews combined yells of ‘CAPTAIN’ and ‘BEIDOU’ before a loud splash and the deep press of water drowned out any other noise but her frantically beating heart.
The captain didn't even care about the sting in her eyes as she opened them underwater. Everything around her was heavily blurred.
She felt the arms of the mermaid dragging her down, and away from the surface.
Shit. Fuck. This can't be how it ends.
She wouldn't let it end like this if she had any say in it.
And so the captain struggled with all her might. Her lungs were starting to burn from the lack of air and her limbs were weak from exhaustion, and to say that the water pressure didn't help either would be an understatement.
She struggled right until she felt soft lips on her own. It was like a breath of fresh air; literally.
The mermaid was keeping her alive as she dragged the pirate down.
The captains limbs went limp in the mermaids arms as she felt the white haired woman wrap herself tighter around Beidou's waist, pulling her into the kiss fiercely.
Beidou had no idea what the woman wanted of her, but she could tell that the mermaid would get it anyway; she just hoped that she wouldn't have to walk on burning coal or really any sort of torture method be used on her, however it was probably inevitable.
The captain was too tired, too worn out to resist anything that the mermaid may do to her.
And finally, after what felt like ages, Beidou felt herself fall back into a pocket of air, the mermaid finally releasing her as she transformed into a human, letting her legs form instead of the tail she had been using for all that time.
‘Captain Beidou, how nice to finally meet you. ’ the woman let Beidou down onto the soft carpet that covered the tiled floor of what looked like a small flat, but underwater. Its entrance was nothing but a waterfall which switched into a solid material when the mermaid flipped a switch on the white walls.
‘Ningguang.’ the pirate anwsered breathlessly.
Beidou had heard of her, the legends, the love poems, and the horror stories that were passed around Liuye by both children and adults alike. The legendary head of the merfolk, reigning over them like a ever looming figure, the Tianquan of the sea, per se.
The woman that stood before her must've been nearly six feet tall, with soft white hair that reached to her knees, and a red ornament right in the dead center of her forehead. Her figure was immaculate to say the least. Beidou thought that the descriptions she had heard hadn't given her justice.
With a smile, Ningguang approached the weakened pirate, kneeling down right in front of her breathless figure.
‘I can asume that I am also infamous in the human realm, then?, ’ the mermaid smiled warmly before relaxing her face back into its neutral expression. ‘Im flattered; however you will see that that is not the reason why I have brought you here, ’
Swiftly, Ningguang brought her face close to Beidous, so utterly close that their noses were practically touching.
‘I have brought you here to make a deal, ’ Beidou could not read the mermaids tone, however her slightly flushed cheeks and darkened eyes gave the mermaids intentions away ever so slightly. ‘..and that is?, ’
The captains voice was barely above a whisper as she was still trying to get her breathing back under control.
‘Your ship today, Captain, came well into my territory. And as I asume that you already know; I do not appreciate such blatant intrusions. So; here is my offer:,’ ––Beidou held her breath.
‘I let your ship return in one piece, with you in it. However in return I want–,’ Beidou felt Ningguangs' steadily darkening red eyes all over her, nearly undressing her with her gaze. The captain shivered.
‘—your body.’ Beidou felt her heart skip a beat as she felt her cheeks burn.
‘In what sense?’ Ningguang chuckled at the captains tone.
The mermaid sat down on the captains thighs, her lips twitching upwards in a smile. ‘I want to fuck you senseless Captain. Is that straightforward enough?’
Beidou felt her neck flush as heat traveled down, below her stomach; and started pooling between her legs.
‘And– And what if I don't?’ the mermaids smile turned sinister.
‘Well, I'll just send my sea monsters up there. Without you; the entire fleet would be done for in minutes; Is that what you want, captain?’
Ningguang knew that the pirate's question held no real meaning behind it, knew that the pirate was not going to pass up such an opportunity. However, if Beidou were to actually refuse, she would not force herself upon her, and neither would she destroy the Crux fleet. In other words, it was an empty threat and they both knew it.
The Captain tensed up, way too exhausted to try and move away from Ningguangs' studying gaze. She pretended to consider it for a minute before relenting, after all, she didn't want to seem too eager.
It was well known that Captain Beidou cared for her crew as if they were of her own flesh and blood; and for the Crux as a whole, for that matter after all.
Not only that; its not as if she was opposed to letting the mermaid have her way with her anyway.
Just the mere thought of that already sent shivers down her spine in anticipation.
Ningguang couldn't help the smile that spread across her features as the captain took off her cape, exposing her neck and shoulders to the mermaid. ‘I'm all yours.’
With a quick glance up to Beidous' face, the mermaid started undressing the pirate, and in what felt like no time at all, Beidous upper body was exposed.
Her nipples hardened at the contact with the slightly chilly air, making Ningguang grin.
Finally. She had the esteemed and well respected captain of the crux under her; shivering at her every touch. But Ningguang wanted more. Oh, so much more.
She wanted the pirate shaking and moaning as loud as she could, mewling at the top of her lungs; begging Ningguang for anything and everything; for her. Moaning her name. She wanted the pirate all for herself. She wanted Beidou to be hers.
‘Gh~Ah-! ’ the pirate clasped a hand on her mouth as the mermaid bit down on her collarbone and started to suck and lick on the mark she had left.
However, soon she broke apart; slightly displeased.
Ningguang shook her head. ‘No no no darling, that simply won't do,’ she glanced up at Beidou.
‘I want to hear you, Beidou. I want to hear you moan out my name. I want to hear you beg for release. I want to hear you. Do I make myself clear?,’ the mermaid ran a hand down the pirate's exposed back; delighting in how Beidou trembles under her touch.
‘Mmmgh.’ Beidou moaned out softly, removing her hand from her mouth.
Ningguang smiled before capturing Beidous lips in her own, making the pirate gasp. And of course, the mermaid took advantage of that; slipping in her tongue into Beidous mouth.
After what felt like an eternity, they finally pulled apart. Their little making out session had left Beidou panting for air, a thin string of saliva connected Ningguang to her before it quickly dissipated.
Oh, how long Ningguang had yearned for this, the captain had no idea.
Ever since the mermaid had heard of the great conqueror of seas, fearless in the face of monsters that even made Ningguang have heart palpitations; she was determined to have her squirming under her, begging for release.
‘N-Ningguang— Haa.. Please! Nhg-’
Beidou had begged for her. And that was all that was necessary to make the mermaid snap.
Ningguang didn't know she had been holding back until she let go.
Suddenly, something seemed to take hold of Ningguang; she didn't even bother teasing the captain and instead opted to practically rip off all of her clothes.
Furiously, she thrust two fingers into the now slightly terrified Beidou, causing the latter to moan out in a combination of pain and pleasure.
‘GH! NINGGUANG~! Slow d-down!’
Unfortunately for Beidou, her pathetic pleas only served to fuel Ningguang further. Her fingers pumped out of Beidou at an alarming speed, and the mermaid reveled in the lewd sound of skin on skin. She could feel the captains wetness coating her fingers as she thrusted them knuckle-deep.
Beidou couldn't keep quiet as waves of pleasure clouded her mind again and again. Her breathy moans were swallowed up by Ningguangs skilled mouth, effectively muffling her.
The captain could feel her peak coming toward her at a rapid pace, could feel the knot in her stomach jolt violently as Ningguangs fingers curled upwards, hitting her most sensitive spot repeatedly.
If anyone were to hear their beloved captain now, they surely would've thought that she was hyperventilating with the amount of whimpers she was letting out alongside her barely audible moans.
Ningguang could feel Beidous walls clenching around her fingers, signaling her closeness to her climax. And finally, with a final hard thrust into Beidou; the captains back arched and she clenched around Ningguangs fingers as if her life depended on it.
With a few more pumps Beidou came undone at the hands of the mermaid, her orgasm making her mind go blank as Ningguang fucked her through it, all the while whispering sweet nothings in the pirates ears.
After a few minutes, Beidou finally relaxed into Ningguangs arms, her legs shook from the power that he mermaid had unleashed on her mere moments before. However, unfortunately for Beidou, the mermaid was far from done with her.
‘W-wait! Ningguang I just— NGH!’ The captain whimpered below her as Ningguang continued to shove her fingers up to the knuckle into the woman's sex, curling them ever so slightly to caress that most sensitive spot.
‘Ningguang— please I-Im— gh!!’ Beidous pleas fell on deaf ears as the mermaid continued to make a mess of her quite skillfully.
The sea tianquan reveled in the moans she ripped out of Beidou. Finally, finally she had her at her mercy. She took delight in the tears of overstimulation that ran down the pirate's face, the shaking in her legs as Ningguang absolutely wrecked her insides with her long fingers.
‘Ah, N-Ning.. Mmh! ’ Beidou whimpered and sobbed out the mermaids name like a chant as she felt herself getting closer and closer to her peak. Whimpered as her oversensitive body twitched and shook with every thrust inside of her.
Beidou clung to Ningguang as her vision started going white; waves of pleasure crashing onto her as she shook and cried out Ningguangs name, arching her back off of the carpet.
Ningguang, in turn noticing how close her pirate was; doubled her efforts even as her hand started going numb from how roughly she was pounding into Beidou.
‘N-Ningguang!! AH! ’ The pirate came with a cry that she was not aware she could make, shaking violently as she mentally begged the gods for Ningguang to take mercy on her and give her a moment.
Unfortunately for her, it seemed that the archons turned a deaf ear on them as she felt another finger slide deep into her, stretching her out as she started shaking.
‘Ningguang- I j-GH! ’ Beidou whined and writhed under the mermaid, torn between giving in fully and letting the mermaid do whatever she had planned to do, and trying to escape the touch of pleasure that was slowly turning into pain. Unfortunately for Beidou's pride, she was a sucker for it.
The mermaid's fingers pumped into the pirate over and over as Beidou started whimpering again, her body shaking as shockwave after shockwave of pleasure crashed into her, turning her thoughts into a incoherent jumble of just Ningguang.
Ningguang's bruising pace was replaced by a softer one, making the captain squirm and whimper as the amount of pleasure was too much and not enough at the same time.
It wasn't long before the Tianquan took her fingers out of the pirate all together, making Beidou open her mouth to– what? Ask Ningguang for more? Ask for the torture to end? What did she want to say?
Before the pirate could start over thinking things, she felt a large and vibrating object press against her entrance, stretching her slightly and making her gasp.
That's right, geo wielder.
The geo formation slipped into Beidou, making her moan and arch as the vibrations shook her to her very core. The mermaid smirked as she saw the wetness that leaked out of the Uncrowned Lord of the Ocean as she waited for her to adjust to the unexpected stretch.
As Beidou prepared herself to nod, Ningguang started slowly taking the phallus out, almost to the tip. The captain was prepared to plead and beg for release, but before she even got a word in the geo phallus slammed into her, again and again and again.
‘Ning.. Haaaa... Hng.. Ning-’ Beidou could feel herself coming close to the edge again, that tightness threatening to snap her mind in half before she finally toppled over the edge with a loud moan, but it didn't stop there.
Ningguang took the phallus out of the brunette, only to then slam her fingers right back in.
The brunette whimpered, tears running down her face and staining her eye patch, making her take the pesky pice of clothing off of her face.
Ningguang was mesmerized to say the least, as she looked at the captain giving herself to her completely, even removing that charming eye patch she always wore.
The slightly pale eye underneath it was beautiful, but she could see why the Lord would have wanted to hide it.
A large scar ran down from her eyebrow to the start of her cheekbone, splitting the pupil in that eye in half. Ningguang couldn't take it anymore, finally she leaned in and kissed the scar lovingly, almost reverently.
She continued peppering kisses around the blind eye, surprising Beidou with the contrast of how roughly she was pounding into her, messing up her insides and making sure that she'll have issues with walking for the next day; and how she peppered kisses to her harmed eye, making the captain tense up every now and then.
Her left was a blind spot, and it triggered her instincts to fight when anyone touched the left side of her face at all, but Ningguang's kisses calmed her down, making her focus on the fingers inside of her as she riled her instincts down.
The last orgasm was powerful, making the Lord shake as she arched, moaning Ningguang's name to the heavens above, the knot inside her breaking and making her feel pleasure the likes of which she has never felt before. The captain felt Ningguang press a soft kiss to her lips before her consciousness gave out.
-- -- -- -- -- -- --
Ningguang, meanwhile, was pumping her fingers almost lazily in and out of Beidou so as to help her come down from her high; and she had to stop herself from giving her another round from the small breathless moans that escaped the pirate's mouth before taking out her fingers, which; (she noted with a twinge of pride) , were covered in orgasm.
The mermaid made a move to untangle herself from Beidou right up until she heard a small sob of overstimulation escape the captains mouth as she slightly grazed her thigh.
When she heard that pitiful noise she just couldn't bring herself to leave the captain here, alone and vulnerable after such a personally intimate experience.
And so Ningguang wrapped an arm around the pirate's waist, the other going to gently brush her fingers through the pirate's let down hair.
They stayed like that until Ningguang felt the captain relax into her, her head lolling into the crook of the mermaid neck as her breathing evened out, with a twinge of happiness the mermaid noted that she had fallen asleep. Only then did Ningguang dare disentangle herself from the pirate, laying her head down onto her own lap; and started debating on what to do with her.
She was definitely not about to let her go. Not so soon, in any case. If she were to take her to her private chambers; well.. She would need to cover her up with something. There was no way in Celestia that she was about to let anyone other than herself see her captain naked.
She was sure that the guards wouldn't dare ask her who it was, or what had happened. And for about the span of a second she considered letting the cloak she had wrapped Beidou in slip ever-so-slightly so as to show her hikey filled neck, but decided against it.
After all, they had both of their reputations to uphold. However, she guessed that being known for having fucked the famous Captain Beidou of The Crux senseless wouldn't even be a blow to her reputation so much as something to brag about. Ningguang smirked at the idea as she picked up the pirate as one would their bride, and set off.
