Low Tide Offering

The station's back door locked with a heavy click. My pulse jumped to match it. Seventy-two hours by myself. No lab partners hovering. No radio check-ins. Just the bunks and the equipment hum and him.

I never gave him a name. Couldn't. Nothing in the reference guides matched. None of the waterproof charts pinned above the sinks had anything close. He was just what lived beneath the pilings. What kept coming back.

The bucket's metal handle dug a line across my palm. Mackerel on ice, the smell cutting and mineral. I left my headlamp on its hook. The moon was barely there, but I'd walked this trail every night for seven days straight.

Tonight the tide had pulled farther out than I'd ever seen. The moon's gravity felt like a fist in my gut, yanking me down the gravel path toward the waterline.

The dock stretched into black. Wood creaked as I stepped onto it. I set the bucket down beside a cleat. The usual slap of waves against the posts was gone. In its place: a wet, rhythmic rasp. Breathing, almost. The water had retreated that far.

I didn't call out. He was already here.

The air shifted first. Got colder. Then the glow started beneath the planks, seeping through the cracks. Blue. A single slow throb. Then another. Patient. Waiting.

I dropped to my knees. The damp soaked through my jeans immediately. I leaned over a gap wide enough to see through.

He'd coiled himself in the exposed tidepools and mud below, half-sunk in the shallow water the ocean left behind. His body didn't have edges so much as suggestions, some dense shadow at the center with limbs spilling out in every direction, sliding over each other in constant motion. The light came from inside. A lattice of glowing veins beneath skin so thin I watched the pulses travel, blue crests rolling through him like slow electricity.

One limb peeled away from the tangle. Thick as my forearm. It rose toward the gap I was looking through, stopped an inch below the wood. Held there.

My fingers fumbled the bucket. I grabbed a mackerel, stiff and cold. Held it over the opening.

The tentacle dropped back. A clicking sound echoed up from the space under the dock. Stones knocking together underwater.

I knew that sound. He'd figured it out. A week ago he would've snatched the fish in a frantic lunge. Now he wanted me to bring it down. The meal wasn't enough anymore. He wanted the hand that fed him.

My throat closed up. I stood. Legs shaking. This was the moment I'd been building toward for days. Empty station. **** low tide. Nobody around to hear a thing.

I walked to the ladder at the dock's far end and started down. The rungs were slick, coated in algae. Cold bit through my sneakers. The air down here was thick, salt and rot and something sharp, like the smell after lightning.

He'd shifted position. No longer directly beneath the planks, but tucked into a deeper pool ringed by black stone. His glow was stronger now, pulses coming faster, sketching out his shape. Bigger than I'd thought. His core was the size of a retriever, a soft mound of muscle with tentacles spilling off it. Some thick as rope. Others thin as wire. They lay in a wet, shifting pile around him.

I stepped off the last rung. My shoe sank into freezing mud. I kicked both sneakers off. Peeled my socks away. Mud squeezed between my toes.

I walked toward him. Still holding the bucket. The fish inside it didn't matter anymore.

He stayed still as I got closer, but the light inside him flared. Bright, sustained blue that lit up the water in his pool. I could see the details now. His skin wasn't smooth, it was covered in thousands of tiny raised bumps. And he was slick with some clear coating that caught the light and shimmered.

I stopped at the pool's edge. My breath came out in clouds.

One of the thick tentacles lifted. Moved through the air toward me. Slow. Deliberate. The tip was blunted, slightly wider than the rest of the limb.

It stopped a foot from my face. Hung there.

This was him asking. This was the question he'd learned to pose.

I dropped the bucket. It hit mud with a wet smack.

I nodded. Stupid human gesture. But he got it. Or he felt the shift in me. The yes radiating off my skin.

The tentacle drifted closer. Touched my cheek.

Two things hit at once: how cold he was, deep ocean cold, and how warm the slime coating him felt. Slick and thick, like gel. It smelled like the sea, but cleaner. Purer.

The tentacle slid down my jaw, tracing the bone, leaving a cool wet line. It moved to my throat. Gentle pressure. My head tipped back on instinct. My pulse hammered where he touched me. The blue light under his skin spiked in rhythm with my heartbeat.

Another tentacle, thinner, crept up my bare calf. The sensation was incredible. The suckers weren't aggressive, not like an octopus. They were soft. Delicate. They stuck to my skin with a faint wet pop and released just as gently, working their way up my leg in a slow massage. Each one left a cool circle that warmed fast.

I reached out. I wanted to touch him too.

The second my fingers made contact with his main body, he shuddered. The light inside him flashed white-hot. I had to blink. His skin was firmer than I expected. Muscular but yielding. The slime coated my palm immediately.

A sound came out of him. Low, resonant hum that I felt through my feet, through my bones.

The tentacle at my throat curled behind my neck. Not squeezing. Just holding me. The one on my leg had reached my jeans. It slipped under the denim, cool slick touch on my bare thigh. I gasped.

He was learning my shape. Mapping me.

The thick tentacle from my face drifted lower, over my shirt. It pressed against my breast and I made a sound. The suckers there were bigger. They latched on through the fabric. Gentle but insistent. The cold seeped through the cotton, followed by that weird warming slime. My nipple went hard and sensitive, aching.

This was why I came down here. This was what I wanted.

"Yes," I whispered. Voice wrecked. "Please."

Everything changed.

The slow exploration stopped. The hum from his core dropped lower, became a vibration I felt in my jaw. The blue light stuttered, then started pulsing fast. Almost strobing.

Two more tentacles wrapped my thighs. Medium thickness. Strong enough to hold me but not hurt. Just enough to pin me in place.

The one on my breast shifted, tugging my shirt up. I helped, yanking it over my head and throwing it into the mud. Night air hit my skin, raised goosebumps everywhere. But where he touched me I was burning.

Another tentacle, thin as a pencil, slid up my stomach. It moved with perfect accuracy. Traced my hip bone. Dipped into my navel. Kept going down. It hooked into my jeans' waistband.

He understood. Of course he did. He'd watched me for a week. This two-legged mammal coming to the water. He knew my shape.

The thin tentacle pulled. My button popped. The zipper slid. The thicker ones around my thighs pushed the denim down until I could step out. I stood there in my underwear, shaking. Not cold. Anticipation. The thrumming inside him was a physical **** now.

The thin tentacle didn't pause. It slipped under my panties' elastic. A cool questing touch that made my stomach clench. It slid down through my hair and found the center of me.

I cried out. The touch was surgically precise. The tip was blunt and soft and coated in that warming slime. It circled my clit once. Twice. A slick slow tease that buckled my knees. The tentacles on my thighs held me upright.

Then it pushed lower. I felt the tip press my entrance. It wasn't cock-like. Thinner. More purposeful. It pushed inside with smooth steady pressure.

The sensation was unreal. The slime was perfect lubricant, slick and thick, but it was his texture. Velvety skin with subtle give, like firm gel. And cool. Deep internal coolness spreading through me as he slid deeper, filling me.

I was panting. My hands gripped the thick tentacles holding me. My head fell back. The thin tentacle pushed all the way in until I felt its base against me. Then it started moving. A slow rhythmic pulse. Not thrusting. Expanding and contracting from inside. Massaging me internally. Each pulse sent a wave of sharp pleasure radiating out.

The blue light was strobing so fast it was almost solid. The hum was constant. Deep drone.

Another thin tentacle found its way between my legs. This one focused on my clit, circling with that same slick precision. The combination was too much. Internal pulse and external stimulation. My orgasm coiled tight and low.

He felt it. The tentacles around me tightened slightly. The hum pitched up. The pulses inside me quickened.

I came with a choked scream. My body convulsed against his grip. Vision whited out. Pleasure was a shockwave from my core to my fingertips to my toes. The tentacle inside me swelled and a fresh gush of warm thick slime filled me, dragging the spasms out longer.

I hung there in his hold. Boneless. Shaking.

Slowly he withdrew the tentacle from inside me. The others loosened. Became soft supports again. The blue light faded to a slow contented pulse. The hum softened to a purr.

Cold air on my wet skin. The smell of him everywhere. I was slick with his coating from neck to thighs.

I opened my eyes. He was still coiled in his pool, tentacles draped over me in a loose possessive net. One of the thick ones lifted and brushed hair off my forehead. The gesture was so tender my chest ached.

I was his discovery as much as he was mine.

I sank into the mud beside his main body. Didn't care about cold or wet. I leaned against him. His skin was cool but the core, where the light was brightest, was warm. I felt the thrum of his life through my spine.

I'd fed the thing under the dock. Now the thing under the dock had fed me.

We stayed that way until grey crept into the sky. The tide would turn soon, crawl back in to reclaim his world. He nudged me with a tentacle. Soft push toward the ladder.

I got dressed with stiff cold fingers. My clothes were damp and smelled like him. Like us.

I climbed the ladder. At the top I looked back. He was just a faint blue pulse in the dark water, retreating.

I left the bucket of mackerel on the dock. He didn't need it anymore.
