Avadakadavra

I awoke in a dark place, my head spinning as my eyes slowly adjusted to the dim light. Once I got hold of my bearings, l realized that I was in a dark cave, a small body of blue water blocking the only way out. I realized quickly that I was in an underwater cave, the walls of which were lined with glowing bioluminescent moss.

A cold breeze blew through the cave, making me shiver, and I noticed I was naked, every part of my body exposed to the cold air of the cave. I looked around desperately, trying to find something to cover my body with, when I heard something in the water. I whipped around, watching the ripples move across the surface.

It was then that i recalled the tales I'd heard of sirens kidnapping humans, and I prayed to the gods that this wasn't the case. I stared at the rippling blue water for a moment, before going back to looking for something to cover my body. I heard the water move again, but this time, I ignored it, thinking to myself that it was just a fish. It was when I heard his voice that I realized it was no little fish.

"Well, hello there~"

I whipped around again, only to come face to face with a huge siren, who was holding himself up from the water to watch me. I yelped and fell back, trying to cover myself with my hands and arms, which only made the siren laugh as he stared at my naked body. I trembled under his gaze, his bright blue eyes seeming to pierce my skin as they glowed in the dark of the cave.

His dark purple tail flicked back and forth in the water, reflecting pink in the dim light of the cave. His dark shimmery skin caught the reflections on the water, and his black fluffy hair dripped with water, sticking to the skin of his forehead. He was, handsome, to say the least. He looked much different than how the stories described sirens, as terrifying beasts with long ratty hair and sharp needle like teeth.

"W-w-where a-am I?"

I stuttered as I spoke, both the cold and my nerves making me sound more scared than I was, or at least that's what I thought. The siren looked at me and chuckled, a deep mocking sound that sent shivers down my spine.

"You're in my home, of course."

He grinned as he answered me, his deep blue eyes seeming to bore into my very soul. I trembled as I tried to speak up again, wanting to get as many answers out of him as I could.

"W-why am I h-here..?"

At this, the siren frowned, glaring at me as he opened his mouth full of sharp shark-like teeth to answer me.

"Why do you care? It's not like you were going anywhere else."

I flinched at his response, wondering what he meant by 'not going anywhere else', and then I remembered. I was trying to kill myself. I'd come to the beach to drown myself, and that's when he must have caught me.

"You finally get it now?"

I looked back up at the looming creature in front of me, and silently nodded.

"Heh, about time. I mean, it's not like you had anything better going on, so I figured, you have a nice body, why not use you as a fuck toy?"

I winced at what he said. A fuck toy? How would that even work? I didn't have much time to think about it before I heard something strange. It sounded like, a song. I bolted up as I realized what the siren was doing. I frantically looked around for an exit, some kind of way out of the cave, but it didn't work. Before I could even think of a way out, the song overtook me.

It felt like I was drunk, or maybe high. All I knew was that I wasn't in control of my body anymore, the only sense of self I had left being a little voice in the back of my mind telling me something wasn't right. I began to walk towards the siren, my feet dipping into the water as the voice screamed in my ears, but the sirens song was so much louder.

I stepped onto the slippery rocks that lay just below the surface of the water, wading deeper and deeper, as the siren led me towards what I assumed would be my death, but instead of drowning me, he had me stop at a ledge, my waist just above the water.

He continued to sing as he pulled something out from under the water, before swimming back to me and sitting on the ledge I now stood on. His song commanded me to sit on his lap, and so I did, my chest just above the water as his scales rubbed against my pussy. He then pulled my hands behind my back and tied them together with something. Only then did his song stop.

I snapped out of my drunken trance and tried to punch him, only to realize what he'd done. I blushed as he pulled me into his chest, his sharp teeth glinting in the dim light the algea provided. He leaned into me and whispered something in my ear as he slipped his hand between my legs.

"By the way, my name's Elai~"

That was the last thing he said before plunging his fingers into my tight virgin hole.

"A-aahh! F-fuck!"

I screamed at the newfound sensation of being invaded. Despite my age, I'd never had sex, never even used any toys, so the feeling of his large, thick fingers slipping in so deep inside of me, stretching me so wide, was both painful and full of pleasure.

I bent backward, my back arching over so that my hair brushed the surface of the water, allowing the siren Elai to bury his face in my chest and bite at the skin of my breasts.

I slowly got used to the feeling of Elai's fingers scissoring my pussy open, the pleasurable feeling of him suckling my breasts aiding in the increasing pleasure building in my body, as a strange feeling built up with it.

A knot, growing tighter and tighter in my stomach, making me shiver. I screamed as it came undone, my pussy fluttering around Elai's fingers, a hot liquid slowly leaking from my pussy as I came down from my high, the sirens large fingers never letting up as they spread my pussy wide for his cock.

Or I should say cocks. Two of them, thick and tapered at the ends, standing proud and tapping against my stomach, precum dripping from their tips. I whimpered when I saw them, whispering to the siren.

"Th-they won't fit-"

"Shhhh, don't worry, we'll make them fit~"

I cried out as he inserted a third finger, sketching me open even more. After making me cum once again from the stimulation of stretching me wide, Elai finally removed his fingers from my pussy.

He grabbed onto my hips and pulled me closer to him, positioning me just above his cocks, the tapered tips teasing my entrance.

I started to cry as he gently pushed his cocks inside, both at the same time. I screamed as they pushed deep inside me, stretching my pussy so wide, filling my body with immense pain and pleasure.

He bottomed out, letting me rest for a moment and adjust to the size and feeling of both his cocks inside me. I clenched around him as he toyed with my breasts, suckling on one nipple while one of his hands pinched and pulled on the other.

I jolted and whined as he began to move inside me, gently guiding me up and down on his cocks.

"A-ah! Aah~"

I gasp and moan, the feeling of riding him so pleasurable. I squirmed and tried to free my hands from their bonds, to no avail. I wanted so desperately to grasp at his soft hair, but the rope kept my hands bound tightly behind my back.

Elai chuckled when he felt my squirming, gripping my waist even tighter than before as he bounced me on his cocks.

"It's no use trying, I've been watching humans tie each other up for centuries. I know how to make your binds nice and tight~"

I moaned again as he slammed me down, and I began to feel the knot in my stomach start to form again, as Elai brought me closer to my third orgasm.

I screamed as I came for a third time, receiving no breaks from the siren as he continued to make me ride him.

I whimpered, now overstimulated, and tried to squirm out of my binds again, only for Elai to bite down on my breast, sending a shockwave of pain through my body.

I cried out as his sharp teeth sunk into my soft skin, drawing blood from my flesh. He quickly lapped it up, the hand that was toying with my other breast moving downwards to play with my clit.

I yelped as his finger began to trace circles around it, making me jolt as, once again, another knot began to form.

"N-no... please... no m-more..."

I whimpered as I felt him begin to move faster, his hips rutting upwards as he moved the hand on my clit to the rocks behind him in order to stabilize himself.

"Don't worry sweetheart, we're almost done~"

He gripped my hips as he moved me up and down, his own rutting upwards into my mine as he chased his high.

I felt myself come undone again, clenching tightly around him as I fell into his chest, no longer able to keep myself upright.

Only a moment later did I feel something warm flood my insides, filling up my tight pussy, making me moan at the strange sensation.

The siren held me close and scooted back a bit, before laying down on the rocks, keeping my head just above the water so I could breathe.

We both panted as we came down from our highs, myself being relieved at finally getting the chance.

"That, felt amazing."

I heard the siren chuckle at his own comment, his hand gently rubbing my back as I began to drift off.

"Perhaps, I'll keep you alive for a bit longer~"

I smiled with pleasure as I closed my eyes and whispered to Elai.

" I wouldn't mind that..."
