Nico stepped onto the sand wearing a white t shirt and black swim trunks. It was a sunny day at Camp Half Blood and everyone was down at the beach kicking back, soaking up sun and splashing in the water. Nico watched Connor pull Alice underwater then come up laughing. He saw someone had buried Clovis while he'd fallen asleep on the sand.

Nico stepped into the tide relishing the cool relief from the burning hot sand on the soles of his feet. He stared out across the horizon, where the sky met the sea.

He'd been lost in his thoughts for a while before he heard someone calling his name.

"Nico!" Percy was way out in the ocean half submerged as he called to him. "Come swim with me!"

Nico was not one for shouting over long distances so he simply shook his head.

"Come on!" Percy called insistent.

Nico sat down on the beach, where the tide barely reached him, expressing his point of staying.

Percy disappeared underwater then reappeared in an impossibly short amount of time much closer to Nico.

"Come on, I'll let you dunk my head underwater," he coaxed.

"Percy you can breathe underwater," Nico pointed out.

"Yeah, but it must be satisfying on some level."

Nico felt a smile tugging on his lips against his will.

"Play with me," Percy whined once again.

Nico sighed, rolled his eyes but complied. He got up and moved further into the water, splashing Percy when he got close enough.

Percy gave a breathtakingly happy smile then splashed him playfully back. They continued on this way, messing around in the water as small waves crashed against them.

Percy might have been endlessly energized being in the water but Nico was not. Eventually, he just lay on the sand, at the edge of the tide and rested.

"Tired already?" Percy smirked. "How about I take you underwater and get you wet in a whole new way?"

Nico opened his eyes and gave him a deadpan look, "no thanks."

"You sure you don't wanna ride the beast?" Percy was smiling lasciviously. "Or, oh! How about we go underwater where you can ride something other than a wave?" He chuckled. "Or how about I just take you underwater." He wiggled his eyebrows suggestively.

Nico snorted dismissively then got up. Just as he was turning away though, he felt something encircle around his ankle. He looked down to see clear water wrapping itself around his leg like it was alive. He turned to look back at Percy and his eyes widened an instant before a giant wave crashed over him, sending reeling back into the sea.

Nico broke the surface of the water, splashing and spitting out water.

"Percy!" he yelled. The boy turned to swim back to the shore but the moment he did, the tide turned against him pulling him back. Nico swam against it but for all his efforts, he remained stationary as the waves kept trying to push him further back. Then suddenly, he felt a yank and was pulled underwater but dry as Percy created an air bubble around them. The son of the sea god grinned with his arms wrapped around Nico's waist then pulled them deeper to the bottom of the ocean floor.

Nico struggled, managing to get free of Percy's grasp and broke out of the air bubble heading for the surface only to have the water push him right back to Percy. His arms closed around his waist again and Nico growled. Damnit underwater was Percy's domain. There was no way he was getting out of this one.

Percy lay him on the ocean floor then settled himself between his legs. They were too far away for any other campers to catch sight of them.

At first, the older boy just pinned his wrists above his head and kissed him deeply then went to suck and nibble on his neck and collarbone. But as he moved his arms down to feel the rest of the slim pale body, Nico thrashed back and tried pushing him off. Percy quickly caught his hands again.

"Nico," he said admonishingly like one would scold a small child. "Now you're going to be a good boy or I'll make this-" he ground down on Nico's hips eliciting a gasp. "Very hard for you," he finished.

Nico glared up at him defiantly and Percy's smile spread slowly and dangerously. He knew that look in his eyes. It was the same one he got with Jason whenever their competitive streaks ran high. It said 'challenge accepted.'

In a flash Percy pulled his white shirt up over his head and tangled it around his hands. While Nico was preoccupied with getting out of that, the sneaky bastard pulled down both their shorts and tossed them away. Nico freed himself just in time for Percy to grab his wrists again in one hand and grind down on his hips. Nico groaned.

Percy went back to kissing him. His tongue probed against Nico's lips seeking entrance but Nico locked his teeth together. Percy reached down to grab his hard on in retaliation and took advantage of his gasp to push his tongue into his mouth. All throughout the French kiss, Percy stroked his member leisurely and Nico's breaths grew faster.

Until, suddenly, he let go. Nico couldn't stop himself, he groaned loudly in protest. He felt Percy smile against his skin then move down to suck on the side of his neck. Nico's breathing had returned to normal before Percy touched him again, stroking slowly over his erection then faster as Nico felt his orgasm approaching. He was panting now, Percy's hand bringing him closer and closer to the very end. Just as he was sure he was going to come, Percy let go. Nico whined loudly feeling completely frustrated.

"Percy!" he complained, utterly annoyed.

"Hmm? What is it?" he faked an innocent voice. Smug bastard knew what he was doing.

Nico ground his teeth together and struggled, uselessly once more against the older boy's hold. Say what you will about the sons of the big three's powers, when it came to size Percy and Jason had more muscle weight on him.

Percy continued with his little game again only this time Nico reached his climax point much quicker being denied it twice before. And same as before, Percy took his hand off right as he was about to blow.

"Stop it!" Nico shouted unwillingly. He hadn't wanted to say anything. He knew Percy wanted him to beg for it or something like that and he didn't want to give him the satisfaction.

"Stop? You want me to stop?" Percy asked unhelpfully. He had now left a pattern of reddish purple marks down Nico's neck and collarbone.

Nico groaned in frustration. Percy continued on this way for a while. Finally, though Nico had enough.

"Percy please!" he pleaded desperately. As much as he hated it, he'd given in. He couldn't take it anymore. He thrust his hips up seeking any kind of friction but Percy cruelly lifted himself away.

"Please what?"

He moaned pitifully. "Stop teasing me, just let me come," he begged.

Percy leaned up to look at him. "Are you going to be a good boy now?"

"Yes!"

"Do exactly what I say?"

"Yes!"

"Are you going to be willing?"

"YES!"

"Hmm, I'm not sure I believe you."

"PERCY PLEASE! I swear, I promise I'll do anything!" Nico sobbed "Just please, please please let me come." He writhed again helplessly.

Percy grinned triumphantly then gave him a chaste kiss. "Hush baby, I've got you. Okay here's the deal. I'll let you come at the end if you're willing and stop resisting. But only when I say so. Come before and I won't let you come for a whole week." Nico looked at him. "I'll tell Jason not to let you either," he promised.

Nico sniffed then nodded, "Okay."

"Good." Percy let go of his wrists, bruised by now surely. Complacently, Nico kept them still.

Percy kissed his swollen lips again. "Now grab under your knees and hold your legs open for me."

Nico glared at him and Percy raised a brow silently daring him to refuse. Nico exhaled then grabbed his legs under the knees, as told, raised them and spread them. He grimaced at the lewd position. This was acting… he was like a whore. Opening his legs, asking to be taken.

Percy, however, seemed to love it. His lascivious smile grew bigger and his eyes darkened as they raked over him. Then suddenly, the air bubble began pulling back until only their top halves were inside it, their legs left out in the ocean. Nico frowned. What was Percy doing? Then the bubble returned to its original shape and they were completely inside it once again. Nico opened his mouth, about to ask what that had been about when he noticed something. All the sand that had been sticking to them had been pushed away along with the water leaving them dry and relatively clean.

Then Percy stuck one finger in his own mouth, coating it thoroughly in saliva before pushing it past his ring of muscles. Nico stiffened up on instinct but then Percy leaned down to kiss a spot on his neck that made him shudder and go limp, relaxing inadvertently. Percy stuck the next finger in his mouth, using Nico's saliva this time to get it wet then pushed it inside him too. Percy scissored his fingers all while hunting for that one spot to make things enjoyable for Nico.

He got it on the next try. One of the three fingers inside him brushed against his prostrate making him gasp and jerk a little. He was nowhere near sensitive enough yet to get a bigger reaction than that but Percy still noticed. He hit that spot again then added a fourth finger.

Normally Nico might have complained about the necessity of stretching him with four fingers. He might have believed Percy was just torturing him by prolonging his orgasm even further but he knew better. One look down was all it took to remind him of the size of Percy's dick. Four fingers indeed. And no matter how many times they did this, Nico still had that hesitant moment of 'I don't think he's going to fit' right before Percy started pushing his way slowly yet steadily into him.

Then he was seated completely inside him, balls resting against his skin and Percy groaned as his body shook slightly and Nico knew, with some sixth sense, that he was holding back on blowing right there.

His head dropped into the hollow against Nico's neck and then he growled low and deep. The sound sent shivers down Nico's back then Percy was pulling out of him again until only his tip remained before pushing back inside.

His rhythm started slow and that was fine, that was all good before suddenly his prostrate was being hit on every thrust and Nico was screaming. Okay, yeah now he was screaming. But he couldn't have stopped if he tried. He had already been holding himself back from coming until Percy said he could but now with the added stimulation, it was pure torture. Pure, blissful, sweet, sweet torture.

"Percy!" he screamed. He didn't have to say anymore as Percy mercifully reached down, stroked his cock and said hoarsely, "you can come." It only took two strokes for him to let go, coming forcefully all over Percy's chest and abs.

His orgasm lasted a long time. Long enough for Percy to thrust harder and faster while he was in the middle of it causing him to groan with over-sensitized pleasure. Percy came only a few moments after, moaning loudly and shooting his thick seed into Nico's ass.

Nico felt the hot, sticky wetness spreading inside him then overflowing past his cheeks. He let his legs collapse, unable to hold them anymore and Percy didn't complain, dropping onto him like a log. Nico didn't mind though, he enjoyed the feeling of weight pressing onto him. Both heroes closed their eyes, too overwhelmed to move.

But then Percy did move, grabbing hold of his waist again and propelling their air bubble to the surface, allowing it to burst as their heads broke above the water. Then he used the waves to push them to beach and thankfully the water cleaned away all traces of their cum leaving the sea just a little bit saltier than what it was.

Nico laid on his back on the sand surprised to see that it was dusk now and everyone had left. Percy leaned down and lifted Nico up and over his shoulder. Somehow he knew the dark haired boy was too boneless to move on his own right now. After all, the water reenergized Percy and Nico had been holding back on his orgasm for a long time.

Dripping, Percy carried the spent boy back into his dark cabin.
