#reader x poseidon

You bite your lower lip, trying to keep a little quiet as Poseidon jerks his leg up. You can't keep the gasp in as thick muscle of his leg causes the fabric of your panties to grind up deliciously against your sex.

The god of the sea smirks as he holds your hips, forcing you down and up as you undulate your hips on your own.

"Is this what you summoned me for? Hm?" Poseidon taunts you. Yet there is no bite in it. No he is rather enjoying the predicament you are in.

The beloved and all powerful Captain of the Grandcypher, reduced to a panting, desperate and blushing mess, chasing your end by grinding against his thigh.

“Is that…us?”

You both heard Poseidon’s laugh and saw each shake of his shoulders through the crystal’s now mirror-like surface. You lifted your hand slowly then waved, watching in awe as your reflection waved back. You rose to the tips of your toes and leaned back and forth, up and down, as if to test the accuracy of the illusion. Only when you noticed Poseidon’s counterpart from the corner of your eye, his liquid fist poorly hiding his snickers, did you finally settle back on your heels and turn to face him properly.

“I would tell you how it all worked, but I wouldn’t want to send that mortal brain of yours spinning,” Poseidon teased with a gentle poke to your forehead. You recoiled and rubbed at where his finger made contact with an intentionally petulant pout. “But, as you can see,” he continued, “Krustyre’s minerals are very good at transmitting and retaining images. I thought it would make for the perfect gift.”

Your ears perked up and you ceased your fidgeting as Poseidon finally took the leaf-wrapped object and extended it toward you. You hesitated, eyes flickering back and forth between Poseidon’s face and his outstretched arm. He raised a single brow at you and you finally relented, accepting the object with both hands. You took a deep breath and slowly began to unweave the verdant palms, revealing-

Yeaaah that's right, you didn't think I'd put it all on tumblr, did you? You can click on the banner above to finally find out what this mystery gift Poseidon has been teasing is 🙂‍↕️

“Okay, so!” Amphitrite clapped her hands together softly then pointed her fingers toward her husband. “The young weaver. What exactly is it about her that has you so out of sorts?”

Poseidon placed his elbows on his knees and sighed. “She is…well, as you say. Deceptively clever and cunning, wrapped in such a sweet and servile exterior. It is…infuriating.”

Amphitrite crossed one arm over the other and pointed an accusatory finger at Poseidon.  “But such a combination alone would not have you this smitten,” she admonished.

“I told you, I’m not-” Amphitrite stared at him through her eyelashes, daring him to finish his sentence. Poseidon let out a deep exhale, knowing full well it was past the point of trying to deny things to her. “She is one of my faithful,” he relented. “No…not just ‘one’. There are few who have ever been as faithful as her. But it’s not just that, it’s… She said something to me, Amphitrite. I haven’t been able to stop thinking about it.”

“Well?” Amphitrite leaned toward him with a playful nudge. “Don’t keep your wife in suspense now.”

“She told me that she follows me because I care,” Poseidon explained through gritted teeth. “Because of the warmth I’ve shown her. It- it irked me.”

“Why? Because she didn’t buy the whole cold, dark, and ruthless image you’re so attached to?” Poseidon turned to his wife with a look that was meant to be stern, but in reality just came off as sullen. Amphitrite rolled her eyes at him. “By the tides, DonDon—you and Zeus always talk about how far above the mortals you are, but I swear you men are all the same when it comes to your reputations.”

“Not helping, Tritē,” Poseidon glowered.

“Well neither are you,” came Amphitrite’s retort. Poseidon did his best not to pout at her. “Have you lain with her yet?”

“...in a manner of speaking.”

“Poseidon, what does that even-” Amphitrite froze, her eyes wide in revolted disbelief. “Is that why you’ve been so glued to the conch shells?”

There, on the cave’s ledge, stood the most gorgeous man you had ever seen. He wore a beautiful set of short-sleeved robes that flowed down his tan, muscular body like a waterfall, complete with the cool tones of the ocean blue. His arms were crossed and one of them was a bright, translucent teal that glistened in the low light as if it were wet. In front of his arms hung two braids and the rest of his long, silky hair fell behind him like the dark of the night giving way to the faintest hint of dawn. Upon his head, he wore a golden laurel that matched the eye-shaped pendant around his neck and contrasted the silver of his gorget and arm bands. He was observing you intently and those deep blue eyes—just as striking as the rest of his sharp, sculpted features—sent fear and arousal coursing through every nerve in your body. Despite your blatant gawking, you still had sense enough to recognize the danger of your current situation. You had no idea how long he had been watching you for, but as soon as you had registered you were not alone, you screamed and propelled yourself backward, away from the ledge. In your panic, you kicked up a large wave of water toward the stranger and, coincidentally, your clothes. Instead of shielding himself, the stranger bent down with such swiftness that the only evidence you had of him moving at all were the discarded garments now in his left hand. “Careful,” the man smirked. “You’ll get your clothes wet, little siren.” You froze in place, nearly sinking as your legs stopped kicking underneath you.  It was him. The gorgeous stranger was Lord Poseidon in the flesh. Oh gods, you were going to faint.

The loud boom of thunder brought you back to the present and you paled as you registered the tempest before you that seemed to have appeared out of nowhere. It was a suffocating curtain of darkness centered upon a fixed point, unnaturally straight like a column supporting the sky. Streaks of bright lighting flashed through the void and the thunder that followed shook your bones, sounding for all the world like a grave warning to stay far, far away. You turned your attention to Poseidon in alarm, only to be further shocked by his nonchalant expression. He noticed your eyes upon him and looked down at you with an easygoing smirk. “Problem, pet?” he asked smugly.

Poseidon didn’t like when you doubted him. It was one of the few things you could do that would elicit a genuinely irritated response in place of his usual snippiness and reciprocated sass. It helped that he rarely gave you reason to question your nigh unshakable trust in him, but now was certainly one of those times. “Lord Poseidon,” you began hesitantly, “are we meant to be heading straight for that storm?”

To your surprise, he did not scoff at you nor scold you. Instead, he tilted his chin downward to look at you properly, a blinding, prismarine grin stretching from finned ear to finned ear. “Of course, my darling servant,” he crooned. “This is the best part.” Poseidon then leaned down and pressed a kiss to your cheek before drawing back to speak into your ear. “Keep your eyes forward, little siren,” he instructed in a hushed yet domineering murmur. “And I suggest you hold on tight.”

Your face fell as you were once again faced with the question, ‘What would this new tapestry depict?’. You looked up toward your father, a nervous plea in your smile. “You sure you don’t have any inspiration for me?”

Halieus shrugged. “I’m not sure it’s my inspiration to give, kiddo.” You whined and threw your head back in exasperation, earning a hearty laugh from your father. “Don’t stress about it too much, delfi. You’ll figure it out.”

“But how?!” you wailed. “I don’t even know what’s out there! What the ocean is really like!” You sank into the stool beside your loom, holding your head in your hands as you ranted. “I’ve never been to sea. I’ve never seen anything outside of this island. Hells, I haven’t even seen all of Ithaca and I’ve lived here my whole life! How am I supposed to capture the majesty of Poseidon’s domain when I haven’t ever truly stepped foot in it?”

You fell back against your loom, supported by the sturdy wood that had held your canvases for years. Tears of frustration stung at the corners of your eyes and you wiped at them furiously, aggravated at how pathetic you felt. You wouldn’t tell your father, but you knew Poseidon in a way few mortals ever would and even still you found yourself stumped. If the tapestry hanging in your home had taken four months to create, how on earth were you supposed to make one to hang in Poseidon’s temple in just six?
