Floating.
It seemed to be the new, main state for you.
First, the turquoise waves floated your flower wreaths away into the open sea. Something in the way the water gently carried your gifts only to suddenly make them disappear, despite no foamy waves raised above the surface, ignited obsessive fascination.
You returned day after day, at various times, repeating the same offering. Each time, when the light crowns of greenery and color reached the breach into the open sea where the black, shimmering with gems monoliths formed a gate, the wreaths suddenly disappeared.
Then that bold compulsion lured you to dip your own body deeper into the cool waters. Layers of your gauzy dress floated atop the surface as you stepped forward. Until it was deep enough to lay yourself into a careful swim.
Quite skilled, you easily floated between the monoliths, watching in awe as the sun glinted in the streaks of jewel tones.
A sudden flick against your ankle disrupted your calm.
A shaky breath before you returned to gentle floating. A second of illusion that popped like a bubble when something wrapped around both of four legs and pulled you under.
The pace of tumbling down into depths was faster than you’d ever imagine. More thick ropes seemed to weave around you, tying you close to something big and quite warm. It pulled you with him so fast that water had no time to fill your lungs.
Everything turned bluer and darker, darker still.
Until it suddenly wasn’t.
Your chest expanded on desperate gulps, catching a fresh, salty breeze. Your body was soaked. The light fabrics of your dress clung heavily to your skin. Beneath you the ground was sturdy, yet coated with something softer. As you brushed your fingers along it, attempting to lift yourself up, sand stuck to your skin.
“Flower priestess.”
A male voice crooned somewhere close. Warm and sweetly raspy, like buckwheat honey with sugar crystals.
Your eyes opened in an instant. The first thing you saw was the high arch of a cave, so light with all the bioluminescent formations whose light bounced off of the scattering of gems. The sand covering the cave floor was an amalgamate of purest white and black as dark as the monolith’s outside.
Flower wreaths were spread all around. Your wreaths.
That’s where they’ve been disappearing to. Or rather snatched. The same way you had been.
Propping yourself on your hands, you lifted yourself into a weakly sitting position and looked toward the source of the voice. Your abductor.
His face was most beautiful, no artisan maestro could ever paint or sculpt this perfection. His pale skin was peppered with gold speckles, forming intricate patterns at his temples then scattering in a spray of disarray across his broad shoulders. His wet hair had that dark shade, as all soaked hair did, but the strands of gold and blue and green were still visible.
His chest was so broad, his skin marble kissed with sunlight. Gold spots continued down his sides, but the color turned darker, rustier. Until they turned inky blue that appeared almost black.
Below his navel, where the V shape of his abdomen should curve into hips, his body grew into the inky form of a giant octopus-like creature. More than ten appendages slithered beneath him, disappearing into the crystalline water. Each thick, constricting. Terrifying.
Was he the mythical monster sailors feared? Or the god of the sea himself?
“I appreciate your offerings,” he moved closer; tentacles as wide as thighs slithered from the water and along the cave floor.
Towards you.
“But it was time I brought you here, so you can worship at my altar with your greatest gift.”
When he smiled the sunlit warmth of his face cracked with the sharpness of his teeth. Pointier than shark’s. Ready to devour.
Two of his tentacles wrapped around your calves, preventing any escape. Three other appendages shot towards you. Different in size: thinner, more agile, sharper at the edges. They tore at your dress, mindless of your scream.
“Shhh,” the monster cooed, weaving his thickest tentacles up your naked legs.
Two more appeared at your sides, trapping your arms in their hold. Then you were being lifted up in the air, scraps of wet fabric plopping down to the ground as your naked form was brought toward the monstrous god.
He angled you up, so you faced him. His hand on your cheek was so humanly warm when he cupped it.
“Ari.” He said, caressing your exposed body with his fingers. “Call me Ari, when you give yourself to me.”
Then he taught you what floating felt really like.
Your body suspended in the air with strong tentacles; light and beyond your control. Spread and explored. So thoroughly the brightness faded into nothingness, sensations rolled into a neverceasing ecstasy.
Thick, powerful tentacles kept you up; moved you the way Ari wished.
Ones adorned with rows of suction cups pressed to your sides and your inner thighs. They didn’t only tease your skin with sucking pressure, but every once in a while sharp spikes flicked from the cups, prickling your skin and pumping your body with something.
Whatever it was, heat burst through your body. A lick of power that seemed to cling to your cells, influencing them beyond your comprehension.
The prickle was painful, making you cry out and jerk in your bonds. But then the other tentacles covered it with an onslaught of pleasure.
Slimmer, pulsing, they rubbed all over you. Kneaded your breasts. Rubbed between your slick folds. One circled your throat in a triple rope.
Your cries of protests mixed with moans.
Something pressed against your cunt; a meaty, wiggling thing drilling itself into your hot, wet cavern. Your body spasmed, mouth opening on a strained moan. The wiggly tentacle’s twin immediately snuck itself between your lips. Just as the other one plunged into your pussy.
“That’s it, my little priestess.” Ari praised, defiling your body. “Accept your god’s will. Let me mold you to what I need.”
Tentacles in your mouth and cunt were fucking into you rhythmically. They drove a little deeper and paused. The pain pierced your skin again, followed by a wave of molten heat. It seemed to shoot through every particle, but then pool toward your centre. It filled your belly.
Then the tentacles were moving again. Faster. More eager to serve their purpose.
Your body twitched, pleasure spiking as the assault continued. It tipped when a third appendage pressed its slimy tip against your rim.
Your scream of protest transformed into one of release, your whole body tensing and quivering as Ari forced his will into your third virginal hole.
“You’re doing so good for me,” his breath teased the skin of your chest; his lips aiming for the stiff points of your nipples.
“Your devotion will help you survive it.”
Warm mouth closed around your nipple, causing a shudder that added to the piling sensations turning your insides liquid and your mind spongy.
Tentacles moved vigorously inside of you. Steady rhythm that quickened, only to pause as deep as your body could take them and pulse wildly. A few seconds in which your body clenched around them on its own volition, begging for that finale they refused to reach.
Then that piercing heat again, another dose of whatever toxin he was injecting into you. And again a rapid fucking that tumbled you over the blinding edge.
“Just a little more and you’ll be ready,” Ari mouthed along the line of your jaw, nipping your chin before he bent to look into your glazed over eyes.
Your mouth was stuffed full of his tentacle, unable to form any retort. Only garbled moans and squeaks. But you looked into his eyes - not only blue, but as if his irises were the reflection of the sea itself; constantly flowing, changing, luring.
Thick tentacles weaved around your legs forced them wider apart, so that Ari fit between them.
He slid one hand over your ass. Spread the other over your mound, his thumb pressing against your clit and drawing tight circles.
“So wet and open. You probably could take my cock now.” He grinned that sharp, scary smile as he watched your pussy stretch around his tentacle. “Oh, you’d struggle to fit it, but take it anyway.”
Scraps of your frayed mind flashed an obscene picture of what the sea god’s cock could look and feel like, if the tentacles desecrating your body at the moment weren’t his default dicks.
“But I need more than just your holes taking me, flower priestess.” The ocean in Ari’s eyes turned stormy.
Suction cups flicked their needle points again, pumping another dose of sweet heat into you. Your eyes squeezed shut as the surge of pain brought an instant heavy roll of orgasm with it.
“That’s it! You’re almost there!” Ari urged you, continuing to torment your clit as his tentacles wiggled in your clenching holes.
“Soon you’ll be ready to take my seed and carry my offspring.”
There wasn’t a cell in your brain left to protest against the finality of his claim. Instead, the swirling orb of heat in your belly responded with pulsing readiness.
The monster - your proclaimed god - continued to break your body with pain and pleasure, until there was so much of it your brain switched off. No thoughts of terror, fighting against your fate, no sentiment over lost human life. There was only this cloudy, floaty state.
Only acceptance as your body filled with Ari’s will.
