Derrick wakes up enveloped in darkness. Everything from head to tail aches. "Ugh. What the abyss happened to me? Last thing I remember I-"
A whale's song echoes not too far away.
"This must be her home... Natasha, huh?" A tremor of aches and pains shakes Derrick off his resting place on the sand. " I- I must've blacked out. But why did she just dump me in this cave?"
Derrick feels around the water and finds a rocky wall. He follows it silently and carefully, in case Natasha is asleep nearby. Derrick can feel his head throbbing from when he blacked out, but he cannot seem to remember what happened just before then. Only the tingly soreness of his manhood distracts him from his other pains.
In the distance, Derrick spots a light, possibly a way out from the bleak cave. He swims as fast as he can, but a shadow immediately blocks the way and snaps its fingers. A sinister purple light floods the cave and dims down to reveal Natasha. The sight of her forces Derrick back against the rough cave wall.
"I thought you'd gone..." Derrick looks to Natasha, realizing his black-out had shattered any recollections he had of her face.
Natasha the cecaelia twists the ringlets her curly black hair. The shine of her purple eyes mirrors an eerie moon. Derrick cannot help but gaze upon the rest of her form. The vision of her pale abyss-skin creeps back into his mind. As a cecaelia, she resembles a mermaid except that the part where one would expect a fish-like tail, there are the tentacles of an octopus. Derrick cannot mistake the allure of her curvaceous body, from her oval face to her plump breasts to her exotic tentacles. Each of those tentacles move and dance about Natasha's bare skin like starved snakes.
Sensing Derrick's fear, Natasha swims up close with a face full of glee. "My, my... You'd think a slave would be more welcoming of his master." She brings herself closer and closer until the plump, succulent warmth of her bosom is pressed up against his chest. "And I'd heard mermen were the best lovers under the sea. You cannot resist any offer of lust. Not only that... Ah, well. That will change after I've broken you in."
"Broken me in?" Despite his situation, Derrick can feel his flesh slowly reach up to half-mast. A simple wink sends a fiery chill through the young merman.
"I was watching you having your pretty little way with that mermaid." Natasha moves a hand down to pinch and tweak one of Derrick's stiff nipples. "It was then in an instant... that I knew I wanted to own you... tame you... break you..."
"Why me?"
"Why?" Natasha giggles loudly to herself. "I guess any merman would have done. You just happened to have been the first I laid my eyes on. And I got to see that legendary virility in action. At that point, I felt that I just had to have you. And now I guess that it's as good a time as ever to mark you mine."
"What?!" The rough edges of the cave wall press into Derrick's back once again.
Natasha just brings herself closer, knowing that mere touch is more than potent enough to cause the merman's body to betray him further. The fear in his eyes barely hides the instinctive lust coursing through his nerves. She moves back a bit to let the soft glow of her dungeon illuminate her captive's features.
Seeing a merman brought to full extension is a sight to behold. Natasha can make out the ridges and veins on his shaft. Derrick's flesh emanates a strange heat that makes Natasha's tentacles tingle. Throbbing, it calls out to her. It demands her presence, yet begs for her permission.
Derrick slumps down to the sand as his will and his body weaken. However, his manhood juts out just as proudly as ever. The merman's eyes glance at the part of her underneath all the tentacles. The part of her he aches for the most. Abandoned by his thoughts and instinct, Derrick looks away in shame.
