This is my own creation for the Percico Event. For the past two years I’ve been working on a Merman!Percy story on Wattpad and Ao3 called Sea Green. This is more of a deleted scene of that story, but you do not have to have read anything from the story to read this. This scene can stand on it’s own perfectly fine.
They sat on the edge of the dock, staring out over the vast blue sea. Being around dinner time, the beach was not nearly as crowded as it should be, and on this part near the private homes they were completely alone. Nico watched the distant waves for a while before looking over at Percy’s face.
His tanned features were set, his green eyes focused and his dark eyebrows drawn together. Nico nudged him with the toe of his sneaker, “what are you thinking?”
“I want to go for a swim,” Percy said before looking over at Nico. Nico’s eyebrows shot up and Percy smiled at the expression. “You don’t want to swim with a merman?”
Nico looked back out into the water. The calm waves were perfect and they still had a few hours of sunlight left in the day. No person was surfing, only one boat was still out miles to the right. “Yeah,” he said, “let’s go.”
Nico stripped down to his swim trunks while Percy left all his clothes on the dock. “Ready?” Percy grabbed Nico’s hand and they jumped in together. The water was cold but contrasted well with the day’s heat. Nico felt their hands separate and quickly wiped the water from his eyes to find where Percy had gone.
He was a few feet away, splashing around right under the water. Before Nico could call out to him, Percy’s head broke the surface. His black hair was plastered to his forehead and his grin from ear to ear. “I missed this!” he called. Nico swam over to him and could see the shimming green under the water.
The current gently knocked against Nico’s chest as he steadied himself with the sea’s motion. He had just felt Percy’s tail flutter by his leg when he was surprised by Percy’s kiss. Nico’s senses were full of the salty taste and smell of sea, but in no way did it distracted him from the warm sensation throughout his body. Suddenly the water wasn’t as cold and the evening sun was brighter than before.
When Percy pulled away, they were both breathless. Percy’s green eyes were shinning, his smile relaxed. While schooling his own facial features to make sure he did not look love sick, Nico realized he was no longer swimming on his own. Percy’s arms around him were the only thing keeping him from slipping under the surface. He quickly gained his own movement back. “Ready to swim?” he asked, his voice so soft to his own ears he was afraid Percy didn't hear him.
“Yeah,” Percy replied. “I’m ready.”
