Daniel cast his line out on the placid water of the lake. The sound echoed off the surrounding mountains. The sky was clear with a few clouds scattered against the pale blue scene. Mountains surrounded the lake, keeping all noise in and all noise out. He was miles from the nearest town and he had hiked a few miles to get back to this spot. It was so calm out here, people rarely fished here because of an old legend about some monster lurked in the deep lake. Daniel read that the lake was a mile deep with a bunch of flooded caves below the depths. It honestly wouldn't surprise him if some massive creature lived in the lake, if anything it gave him hope that there were still places and things man has not discovered.
Daniel felt a tug on his line and he jerked the rod upwards, sinking the hook. He reeled as the fish in as it fought against him. It was big, whatever it was. He continued reeling until he pulled a massive Rainbow Trout out of the water.
"Well you're a big fella aren't you!" Daniel commented as he pulled the hook out of the fish's mouth.
The fish swam away quickly, back towards the safety of the deeper water. Daniel only kept fish when he had to eat. This was just a nice way to spend the afternoon. He cast his line out again and laid down on a rock. He took off his shoes and let his toes touch the glassy surface of the lake. It wasn't long before he felt himself start to drift off to sleep so he reeled in his line and set it next to him before closing his eyes and taking a nap.
Daniel stirred in his sleep as he could have sworn he felt some slimy thing brush by his toes. Probably a fish, he thought as he ignored whatever it was. Unbeknownst to him, several tentacles slowly and quietly rose out of the water around him. The moved all at once, one wrapped around his waist, pinning his arms to his side, another wrapped around his neck and squeezed. Daniel immediately started thrashing but the tentacles were massive and with strength to match, he was helpless to the slimy appendages. They lifted him off the rock and pulled him into the lake. Daniel at least had the sense to take a breath before he was submerged.
Daniel continued to thrash wildly as the tentacles pulled him deeper into the lake. Panic set in as Daniel struggled to free himself. He saw the tentacles were connected to something, but he couldn't make it out through the darkness below water. The thing was pulling him into one of the many underwater caverns. The monster entered the cave, pulling Daniel along with it. His air was running out as he could see where cavern opened up to a grotto made out of an air pocket. The monster put him above the water, allowing air to flow into his lungs but the tentacles continued their grip on his body.
He looked around to see several collapsed pillars of antediluvian origin. Then the monster to whom the tentacles belonged to rose out of the water. It was a massive woman, just her torso was at least a5 feet tall! Daniel was taken aback as he saw her aqua-green skin, pointed ears, smooth tendrils sprouted from her head resembling hair. She also had an eye dangling out from her forehead. It resembled something like the lure of an anglerfish. Then to surprise Daniel further, the thing spoke.
"Human, do you know who I am?" The thing spoke.
"N-n... No..." Daniel stuttered, his voice trembling in fear.
"I am Nerthus, Goddess of this lake. I saw you fishing, and I thought I could give you a purpose." She said in a powerful tone.
"W-wh-What?" Daniel asked, still very frightened.
"You see...it's been a while since anyone has come to visit my home. Much less, someone as cute as you..." Nerthus said seductively as a large but still slender finger slowly slid up his stomach.
"Uh...ah..." Daniel uttered.
"Let's get rid of those clothes, you won't need them anymore." Nerthus said as several tentacles surfaces and tore his clothes off his body like they were paper.
Daniel blushed heavily as Nerthus drank in his form. His body dripping with water and cold sweat. A smirk grew on her face as the tentacles pulled his body closer to hers. She slid her arm under his back, cupping his ass with one large hand. The tentacle around his waist let go and slid back beneath the water. Nerthus then used her fingers to firmly part his thighs, his arms looked for something to hold on to. A tentacle gently wrapped around his wrist, more in a tender hold than a forceful grip. His other hand found purchase on her right breast, more specifically, her dinner-plate sized nipple.
