2 - The Awakening of Frustration

Roberto's hands tangled in Kai's damp hair, pulling forcefully as he guided the siren's head towards his crotch. The boat swayed gently under the weight of both, creating a hypnotic rhythm that accompanied the muffled moans escaping the siren's throat.

"Open that mouth, creature," Roberto growled, his voice laden with authority as he unbuttoned his pants. "Let's see what else you're good for besides singing."

Kai obeyed without resistance, his lips parting to receive the fisherman's thick cock. The salty taste, mixed with the aroma of sweat and sea, filled his senses as Roberto began to fuck his mouth with slow but determined movements. The man's rough hands grasped his head, controlling every movement, every breath.

"That's it, little fish," Roberto murmured, pushing deeper. "Swallow it all."

The siren felt his eyes filling with tears as he struggled to accommodate the full length in his throat. His scales glistened under the moonlight, creating silver flashes on the water's surface surrounding the boat. Roberto increased the pace, his hips moving with greater urgency.

The taste of semen still lingered in his mouth, vividly reminding him of every second of submission.

But his curiosity was stronger than his confusion. Instead of swimming away, Kai stayed close, hiding among the rocks and algae, watching what Roberto would do next.

He didn't have to wait long. Another boat approached, and from it descended a young man of no more than 25 years. He was slender, with soft features and a way of moving that immediately screamed submission. His eyes were large and expressive, and when he saw Roberto, his smile was timid but expectant.

"You're late, Marco," Roberto said with a severe tone, though his eyes sparkled with amusement.

"I'm sorry, Roberto," Marco replied, lowering his head. "I had to wait for my parents to fall asleep."

"Excuses," Roberto growled, grabbing the young man by the arm and pulling him towards the boat. "I don't like excuses."
