3 - The fulfilled obsession

Kai's transformation had lasted eighteen hours when he finally saw Roberto's boat approaching the coast. During that entire time, he had been waiting among the rocks, naked and shivering, his new human body exposed to the elements while planning how to approach the fisherman.

He didn't need an elaborate plan. He simply threw himself into the water and started swimming towards the boat, pretending to be in danger.

"Help!" he shouted, splashing dramatically. "I can't make it to shore!"

Roberto directed his boat towards him, but when Kai climbed on board, soaked and completely naked, the fisherman looked at him with a mixture of suspicion and recognition.

"You," Roberto murmured, studying those green eyes that seemed so familiar to him. "I know you."

"No, I..." Kai began, but Roberto grabbed him by the neck and pushed him against the bottom of the boat.

"You're the merman who was watching me, aren't you?" Roberto growled, his hand tightening around Kai's throat. "Did you think I was an idiot? Those green eyes are unmistakable."

Kai felt panic and excitement at the same time. Roberto had discovered his identity, but instead of fleeing, he felt more excited than ever to be completely exposed to the dominant man.

"Yes," Kai panted, not trying to deny it anymore. "It's me."

Roberto laughed, a cruel and ruthless sound. "How pathetic you are. Did you transform into a human just so I could possess you?"

"Yes."

"And how much did this transformation cost you?" Roberto loosened his grip on Kai's neck slightly, but kept him immobilized.

"A year of my life," Kai confessed, feeling how humiliation excited him even more.

"A whole year," Roberto spat into the water. "How desperate you must be to sacrifice your own life just to feel my cock inside you."

"I'm desperate," Kai whimpered. "I've been obsessed with you since I saw you with Marco."

"Ah, so you were spying on us like the pervert you are," Roberto slapped Kai's face, turning it to the side. "Did you like seeing how I dominated him?"

"Yes, sir."

"And now you want the same thing?"

"Please."

Roberto sat up and began to unbutton his pants with slow, deliberate movements. "Alright, creature. I'll give you exactly what you want. But don't expect me to be gentle with you."

He pulled out his member, already semi-erect, and waved it in front of Kai's face. "First, you're going to suck it until it's hard. And you'd better do it well."

Kai threw himself at Roberto's cock with desperation, licking and sucking with an intensity that bordered on madness. Roberto grabbed Kai's head with both hands and began to brutally penetrate his mouth.

"That's it, little fish," Roberto growled. "Suck like the desperate bitch you are."

Tears streamed down Kai's face as he struggled to breathe, but he didn't try to pull away even onc...
