Nico is not sure if he likes underwater kisses or not.
In a way, it is terrifying – a son of Hades letting himself be so vulnerable and restrained in Poseidon’s reign while he kisses the god’s son.
In another, it’s thrilling – just like doing anything else with Percy. He can feel the excitement building inside of him as he steps into the water. He can’t resist the way Percy laughs at him when he shows his concern about “how to breathe” for so long; the way the sea son tells him that, luckily, breathing won’t be their main focus at the moment.
One day, Nico told Percy that he couldn’t seem to choose if underwater kisses were great or not after all. Automatically, Percy took his hand and led him to the sea. When Nico wondered what the older boy was doing, Percy only smirked and replied. “We’ll have to keep doing this until you finally get to a conclusion”.
Nico made it sure to always stay in doubt.
