Nico groaned as he gingerly sat down on one of the beanbags that Percy had filled the Poseidon cabin with. Will watched him with a poorly-hidden smirk, although his own legs were pretty sore too. When they'd gotten back to camp last night, he'd had a long bath and actually relaxed. He was pretty sure Nico had gone straight to the training arena until it was dark. He loved Nico but he wasn't the best at actually taking care of himself.

He sat next to Nico, taking his boyfriend's hand without a second thought. Piper was throwing marshmallows in the air and Annabeth and Leo were trying to catch them in their mouths. Percy and Jason seemed to be arm-wrestling, but they looked over with a grin and wave. Everyone else was at Camp Jupiter, as they normally were. Nico spent time at Camp Jupiter but he liked staying with Will at Camp Half-Blood most of the time.

"Hey Nico, what's up with your legs?" Percy called, a concerned scrunch to his face. Nico sent a fleeting panicked look at Will, unwilling to actually tell the group why they were in pain. He had a feeling he was blushing just as much as Nico was. Nico leaned over for a can of Coca Cola to try and deflect the question. Will stayed silent as well, still trying to fight a laugh at Nico's embarrassment.

Percy gasped suddenly as he clicked into the situation. Jason slammed his arm against the table, winning the game before focusing all of his attention on Nico, who was beginning to squirm at the eyes on him.

"You guys did the do!" He squawked, and Nico's drink was snorted out of his nostrils in shock.

"What, no-!"

"You're fifteen years old! I hope you used protection! If not, I'm very disappointed in you!" Percy declared. Leo was shaking his head and tutting with a massive grin spread across his face. Will was not laughing anymore, he could feel his face going bright red.

"And you, Will!" Percy turned on Will, his hands on his hips. Will wondered why there wasn't Apollo-kids-version of shadow-travelling. Sun-travelling. Or maybe just pegging it out of the nearest door or window. "I'm even more disappointed in you for your behaviour with my son!"

Nico looked mortified, and Will gripped his hand tighter. If Nico was going to shadow-travel away, he was sure as Hades going to take Will with him.

"Percy-" Annabeth started, but she was laughing too much to continue.

"We didn't do anything!" Will burst out. "We went trampolining?"

Percy fell silent for a moment while everyone else in the room doubled over with laughter. Annabeth was clutching Piper and Leo almost slipped right off the beanbag he was on.

"We went trampolining at the new place in town for like three hours." Will elaborated.

"It was meant for children." Nico said, looking rather put out that Will had told the others, although he was glad that Percy didn't think he and Will had frickle frackled. "It was embarrassing." He crossed his arms, but the effect was lost as he didn't let go of Will's hand. "Wait you really thought I'd had sex?"

Percy paused for a moment and decided to dismiss the question altogether. He was glad he'd raised his son properly but he wasn't have the sex talk just yet.

"So, anyway, where is this trampoline park?"
