Author's Note: I'm sorry Will
Nico knows that this is wrong.
He knows he's with Will; the countless dates and kisses that they share are testaments of their budding relationship. But as Will plants feathery kisses across his neck or squeezes his thighs, he can't help but imagine that it was Jason's kisses instead, Jason's big hands on his skin. The thoughts get to him, make him cum so hard before bringing the feeling of guilt in his chest. He wants to cry whenever Will tells him 'I love you' after their intimate moments. He doesn't feel that he deserves those words.
When they finish each other and turn to their sides of the bed to sleep, the sinning begins.
Because in those dreams, where no one watches and Morpheus judges, he sees Jason.
Jason.
This isn't a figment of his imagination or a product of his subconscious wants; no, this is the real Jason, his essence, his soul, connected to Nico through some dream magic that Nico really doesn't care about. It's been happening every night since the end of the War with Gaea, continuing over five years without fail. At first, Jason and Nico had been alarmed, thinking that this was some sort of summoning from the gods, but then it became a haven where Jason retreats from a tired day of being a demigod and Nico turns to when he and Will fight.
Then before Nico knows it, their dreams have become their place of rendezvous, where Jason can kiss Nico as much as he wants, and Nico can scream Jason's name to the skies. Nico grimaces on how long they've been keeping this affair.
But the moment that Jason presses Nico on the wall of this dream apartment, planting rough hungry kisses to his neck and collarbone, the son of Hades forgets it all. Forgets that Will has proposed to him, that Nico has accepted; ignores the ring on Jason's finger, the daughter he probably tucks at night. This is their dream, their fantasy. Reality can wait tomorrow.
Nico sighs when Jason moves to suck his chest, to play with his nipples and pectorals in a way that Will has never done. In return, Nico slides his hands against Jason's abs, appreciating its firmness and the scars he received from questing. When he thumbs Jason's nipple, Jason growls and sucks on Nico's nipples so hard that he mewls.
"Jason, Jason," he moans, temporarily forgetting every other word in his vocabulary – loyalty, infidelity, Will. He can feel Jason's smirk against his skin, feel the bump of the son of Jupiter's lip scar. Then Jason removes himself from Nico's chest and plants a rough kiss on Nico's lips, all while squeezing the son of Hades' ass through the fabric of the pajamas. Nico moans in Jason's mouth when he feels a finger rubbing through his clothed entrance. He hungers for Jason's thick digits inside him.
"Not yet," Jason murmurs against his ear. Nico feels Jason's hardness, and he has half the mind to grind his erection against Jason's. "I want this to last longer." Because in these dreams, once they come, they come back to reality.
And reality has never been sweet and blissful as this.
They keep up with their kisses and groping until Nico can't restrain his desires. He pushes Jason on the bed and Jason lets him, guiding his ass on the son of Jupiter's cock. Then he slams himself into Jason, taking his breath away and throwing Jason's self-control. The feeling of Jason's cock inside him makes him so full, so complete that Nico can't get enough of it, slams himself into the cock even deeper and harder. He knows Jason is as obsessed with this feeling too, with the way he grabs Nico's hips and the rapid thrust of his hips.
They change their positions at every chance they get. Now, Nico is sitting on Jason's lap, his arms around Jason's shoulders. He lets out a scream when Jason bites his skin at the same time as the son of Jupiter touches his prostate. Breathless, Nico lets his forehead rest on Jason's, and they stare at each other's eyes. From their eyes, they can see every bit of affection and love that they've hid from the others for years.
They love each other, they need each other, they can't let go of each other. But in reality, loving each other has never been so easy.
When Nico is about to come, Jason stills and grabs the base of Nico's cock. Nico looks at Jason questioningly, before Jason reaches to give him a passionate kiss. Nico almost wants to cry on how right it felt. "I love you," Jason says before cumming onto Nico and letting Nico cum on himself. The feeling sends strong shocks of pleasure in him that his vision goes white and the whole dream evaporates.
Nico sees Will after every dream.
Will has a warm smile on his face when Nico finally rouses from his dream. Just as his routine predicted, he reaches up to Nico's sweaty face and gives a morning kiss on his forehead. He tells Nico to get his lazy ass off the bed because they have a long day ahead of them. The cum stains on Nico's thighs and the dried tears on the son of Hades' cheeks goes unnoticed.
Then, Nico reaches out and kisses Will, pulling the son of Apollo back into bed. He lets Will make love to him all morning, on the sticky sheets where he would've made love to Jason.
