I stood by the edge of the rocks and tried to peek down. The last night's storm had passed and the salty waves splashed against the waves almost gently now. Just barely, I managed to glimpse at the underwater cave below them.

I had already undressed most of my clothes, leaving only my short pants and the bag around my waist. My grandfather had been a water nymph, making me somewhat proficient in water-related things. The townspeople had always harassed my family because of our heritage, but I was determined to change that.

The village I had grown up in was poor, the local lady drew high taxes from us as the shacks around us rotted. Now, I had little love towards the villagers, but my mother loved her hometown, even though they treated her like shit. With enough gold, I could help my family to gain more prestige and help the village.

And I knew just where to get it.

Unknowns to them, I had learned about an ancient elven ruin beneath the village. There were no records of it on local history books and I'd never heard about it from the elders. No one knew about the place, which must have meant it had stayed untouched. Some time ago there had been a large earthquake which had revealed the cave and I had already made some assessing dives into it. The cave itself was deep, too deep for land-dwelling humanoids, but even though it had been hard even for me, I had managed to dive deep enough to find a large air pocket within. There, I had seen a large stone gate, which looked elven. If I could enter it and find loot, I could make more gold than I had ever seen.

Determined to go through with my plan, I tied my wavy hair into a bun, took a deep breath, and jumped. As I splashed into the water, coldness surrounded me, swallowing me firmly into its grasp. I let my momentum do the hardest part for me and I sank near the cave's entrance. I began to swim towards it, only a faint light from my necklace guiding me within. Just as I reached the entrance I could feel the rocks tremor, making the water vibrate. It was another earthquake and I hastily swam inside, scared to be outside if something happened. The tremors did not last long and I would have sighed in relief if I had been able to, but I had to preserve the air.

There was absolutely no plant life in the cave, everything was completely dark. The water pressure put a strain on my lungs, but I knew I would find a small air pocket nearby. Just as my lungs began to burn, I surfaced and breathed slowly. I was unsure if the air I was breathing was as ancient as the door I had found or if there were small cracks in the stone, letting fresh air in. I steadied myself and dived again.

The next air pocket would be closer than the one between the cave and the surface. Most of my mind was focused on the dive, but some part of me trailed off and I found myself thinking about the lady who ruled this land. Had she known about this cave, she would have sent in people who could breathe underwater and claimed all the treasures inside for herself. In fact, it was only a matter of time until someone else would find it and tell everyone else about it. I wished I had had more time to prepare, maybe get a few potions to help me swim or hold my breath longer, but it was what it was, at least I was here now, sure about my ability to make this trip.

The dark walls of the cavern closed in and the water turned even colder as I got deeper. At first, I had been able to swim without touching the walls, but now I had to grab them to be able to move. The walls were coarse and full of sharp pointy edges, so I had to be careful where I put my hand. There was a small opening I had to squeeze myself into to get into the next part of the cave. Slowly, I began to blow air out of my lungs to make my chest smaller and pulled myself in. The earthquake had made the opening slightly smaller, but I managed to wrench myself through it, my wiggling had used more time than expected and I could feel my lungs burning again.

Luckily, the second air pocket was just right above me and I swam to it quickly. This time I gasped for air as I surfaced. The quakes had changed the previous opening, then I was in trouble. The next part took my thought even smaller opening, but I knew I could swim back here if I couldn't swim through it. When I had inspected the cave, it had been easy for me to dive in and out, but now I had first been startled by the second quake and then I had almost gotten myself stuck, both had made me lose time and precious air. I had to think carefully if I was brash enough to go in after all. This part of the cave was a lot wider than the previous part, so I didn't need to be as careful as before, but it only made finding the next opening harder.

Suddenly, I felt something brush against my calf and I screamed, when I looked down, I saw a swarm of fish flit past my legs towards the crack I had just come from. The faint light my necklace was giving must have tricked them into believing this was the way out and I chuckled a little bit, feeling much calmer now. I went through my plan again, nodded, and dove again.

It didn't take long for me to find the next opening. It was still there, but the quake had made it close up a little too. I decided to try to pry myself in nonetheless. Again, I released some air from my lungs and began to slide in. Getting my shoulders past the rocks was the hardest part, but I managed to pull the top of my body through, Just as I began to rejoice my hips got stuck. I had to calm myself down first before I attempted to wiggle myself free again, knowing I still had plenty of air left in my lungs for the next air pocket.

Then the earth moved again. The air escaped my lungs as I screamed when I felt the boulders crush my waist, not breaking anything, but pinning me between them. I began to panic, desperately trying to wiggle myself free, regretting my choices. My lungs burned and I wanted to open my mouth and take in the nonexistent air. My whole body tensed up as I begged for the gods to save me, but I knew I was alone. Each movement felt like a torturous eternity. Holding the last of my breath was killing me and the lack of air was blurring my view. Somewhere in the edge of my vision, I saw something large move, swimming closer.

Just as I was almost forced to gasp in the water I heard a voice inside my head.

"ᴡᴀɪᴛ" it said and the water vibrated around me when suddenly a small bubble covered my head and I could breathe again. I gasped loudly, thanking the gods for saving me. The water was dark and I could only see a vaguely humanoid shape farther away.

"Who are you?" I asked, trying to composure myself. Still tugged between the rocks.

"ɪ ᴀᴍ ᴋʜᴀʀᴀ ᴀɴᴅ ᴛʜɪꜱ ɪꜱ ᴍʏ ᴅᴇɴ, ʏᴏᴜ ᴛʀᴇꜱᴘᴀꜱꜱɪɴɢ, ᴛᴡᴏ-ʟᴇɢꜱ," the voice inside of my head said.

The creature swam closer and I finally saw him. He was a handsome man, his bottom half had ten tentacle-like limbs and the top half resembled elven. His skin was decorated with sharp scales, glimmering in blue against my pendant's light. His long, thick, and dark hair flowed freely in the water, reaching the tips of his tentacles. The creature's tentacles began to slither across my body, observing it. The limbs had suction cups that pressed against my bare skin. One of the tentacles found my groin and pressed hard through my pants, making me mewl. My sudden sound startled the creature and he pulled his limbs off of me.

He swam back and observed me from farther away, before determining I wasn't a threat and returning to me. His tentacles began to inspect my body again, tickling me. One tendril curled against my nipple, which was hardened by the cold water. The sensation made me jolt, but the creature did not get startled this time. Soon, his other tentacle found my other nipple, attaching itself to it as the third one began to curl around my neck all the way to my lips, muffling my possible refusal.

I was helplessly stuck between the boulders as the monster slipped his appendages into my pants and found both of my holes. He seemed to be intrigued by my body, not caring what I might want. Two of his ten tentacles rubbed against my holes, the third one soon joining in and beginning to coil around my clit, I moaned against the tendril on my lips and suddenly it pushed in. The tentacle explored my mouth, moving inside and out.

All of his tentacles were about the same width and length. The tips were as wide as one's thumbs and with each fingertip's worth of length they quadrupled in size, joining together somewhere where his thighs should have been. Only two were slightly bigger and longer, but they were nowhere near me.

The one on my rear began to rim my hole as the other one began to circle my pussy, slowly pushing in. I tried to wiggle away, but the tentacles and the boulders kept me tightly in place. Besides, I realized if I tried to escape, he might cast my little magical air bubble away and whatever denial I had in me turned into arousal as the creature rubbed my nipples and clit. Instinctively, I began to match his movements, opening my legs as wide as I could.

I could see that the creature enjoyed playing with me, his face had turned from a stern look to a passionate one as his tendrils hastened their movements, the ones moving around my holes began to prod in, and with one swift push, both of them pummeled deep within, the one on my mouth muffled my loud moan as I felt them fill me completely.

Feverishly, the creature hammered into me, the force of it made my pants rip and I could see the tentacles pistoning into my holes. With each stroke, they seemed to gain more thickness. It didn't take long for my body and mind to break down and I came, my insides tightened around the tendrils, forcing them to slow their pace.

Please with the results, the creature pulled the tentacles from my holes and wrapped them around my waist, easily freeing me from my rocky prison. My waist hurt and it had been bruised by the rocks, but the monster was careful not to put pressure on my wounds. He pulled me closer, pulling my pants off, or at least what was left of them, and began to prob my sore holes with the two larger tentacles. Their fatty tips popped into me and I could feel them move inside me, slowly at first, but as my body relaxed more, they began to move more rapidly. He still had one tendril in my mouth and around my clit, both matching the pace the other two had.

The creature had given me no time to rest, ramming into my already sensitive body even deeper than before, the two hefty tips bulged my belly with each thrust. I could feel tears forming under my eyes as the stimulation got almost unbearable. The tip in my mouth thrusted even deeper into my throat and I swore it could touch the other two inside me. I was hopelessly impaled by the three tentacles, all thrusting in at the same time and then back out.

I couldn't stop myself from cumming, this time the feeling was way more intense, but the vicious ramming did not stop. The creature's thrusts got faster and faster when suddenly it stopped and the tips inside my pussy and ass exploded. Filling my guts and womb with large slimy loads, not anything like I had ever felt before. One of the tendrils pulled out and some of his seed was released into the water before he drove it in again. The seed left outside slowly sank into the darkness, but I saw it and realized why it had felt different.

His loads were encased inside soft egg-like capsules about the size of duck eggs. Now I had multiple inside me and the creature kept forcing even more in. Without saying anything, he began to swim even deeper into the cave and pulled me with him, still keeping the tendrils inside and pumping more of his seed into me. I watched as they made my belly protrude even more.

Soon, we entered another underwater grotto which seemed to be the creature's home and it had been decorated with various elven trinkets and chattel. The baubles around us glowed gently, lightning the area around us. He lifted my weary body onto a rock, which was above the water level, bursting the air bubble around my head. Then he pushed himself up, laying next to me as his tendrils pushed load after load into me. The one on my clit carefully massaged it, keeping me still aroused. The other two that had harassed my nipples were swirled against my wrists, keeping me from moving or pushing him away, not that I had the energy or even wished to do so.

"ɪ ʜᴀᴠᴇ ʟɪᴠᴇᴅ ʜᴇʀᴇ ꜰᴏʀ ᴏᴠᴇʀ ᴀ ᴛʜᴏᴜꜱᴀɴᴅ ʏᴇᴀʀꜱ ᴀʟᴏɴᴇ, ɪ'ᴠᴇɴ'ᴛ ʜᴀᴅ ᴀ ᴍᴀᴛᴇ ɪɴ ᴀ ʟᴏɴɢ ᴛɪᴍᴇ." the voice inside my head said, but I was unable to say anything back as I writhed underneath his tendrils, his loads spreading me more and more, shifting my guts. Every bump that passed my entrances filled me with a blissful sensation. The one in my mouth finally pulled out and I began to pant loudly as my third climax reached my insides. My hips bucked against his tentacles as I came.

There seemed to be no end to his loads, my belly was already thrice the normal size when the creature finally crawled on top of me, sealing my lips with his and rammed his tentacles in one last time. He let out a bellowing moan and forced in the last few loads. We both huffed as he collapsed on top of me and let his soft tendrils still move slightly inside me.

"ʏᴏᴜ ʜᴀᴠᴇ ʙᴇᴇɴ ᴀ ɢᴏᴏᴅ ᴍᴀᴛᴇ", his voice rang wearily inside my mind, "ᴏɴᴄᴇ ʏᴏᴜ'ᴠᴇ ʀᴇꜱᴛᴇᴅ, ɪ ᴡɪʟʟ ʜᴇʟᴘ ʏᴏᴜ ᴏᴜᴛ."

I could feel the small bumps protruding from my lower abdomen with my palm. I gently patted them, feeling fulfilled.

"Listen..." I whispered and the creature raised his head, waiting curiously for what I was going to say next.

"There is an elven ruin here and I would like to have some goods from there if it's not too much to ask?" I inquired carefully, not sure what he might say back. The creature seemed to think about it for a moment before he answered.

"ɪᴛ ꜱʜᴀʟʟ ʙᴇ ʏᴏᴜʀꜱ," he said before adding "ᴀɴᴅ ɪɴ ᴛᴜʀɴ, ɪꜰ ʏᴏᴜ ɴᴇᴇᴅ ᴍᴏʀᴇ, ɪ ᴡɪʟʟ ʀᴇQᴜɪʀᴇ ꜰᴜᴛʜᴇʀ ᴏꜰ ʏᴏᴜʀ ꜱᴇʀᴠɪᴄᴇꜱ."

"You mean services like I just gave you?" I asked and he nodded back, smiling at me.

"I believe that can be arranged," I replied back with a smile.

Before leaving the underwater cave, I decided to rest there for a while, admiring my swollen belly and thinking about the possibilities my future now held.
