A/N: In this one-shot, Nico has breasts and a penis.
Ship: Percico
As a reminder, all of my steamy/smut one-shots are adults-only. Children, please skip, thank you! Also, another reminder, the characters are adults in my work. Thank you, again!

Nico smiled, taking his shirt off painfully slow, giving a little show for Percy. He tossed his shirt on the ground and crawled up to Percy, meeting his face. They were sitting on the bed, and for the first time, Percy wanted to get handsy with Nico.

Nico sat in front of Nico, his breasts completely out. They were new, implants, but he had already gotten them by the time him and Percy started dating two months ago.

"You like them?" Nico asked, trying to sound as sweet as possible. They were a perfect size for him, just the right size to fit in someone's hand but not drown them if they wanted to give them a kiss.

Percy's eyes were wide and his blush spanned across his entire face. He nodded, staring at them and glancing up at Nico hesitantly.

"Touch them," Nico urged.

Percy hesitated, finding the order awkward.

Nico bit his lip, "Let's kiss first then."

Percy nodded, leaning in silently. They started kissing. It wasn't deep, but it was passionate. Nico scooted closer, and soon enough, his breasts were pressed against Percy's chest.

"Take your shift off..." Nico moaned in-between kisses.

Percy obeyed, falling completely submissive to Nico.

Nico pressed his breasts to Nico's bare chest now, running a hand down his lower stomach.

Percy squirmed, making Nico smile into the kisses.

"You like when I feel you up like that?" Nico asked, knowing the answer was yes.

With a darkening blush, Percy nodded, "Keep doing what you're doing."

Nico nodded, running his hand up and down Percy's abs.

After a little bit, they naturally pulled apart. Nico sat back a little, showing Percy his breasts once again. They needed attention.

Percy glanced down at them, noticing immediately.

Nico hesitated, than took Percy's hand. "Stop me if you want to," he reminded, earning a nod in return.

Nico squeezed Percy's hand, than pulled it to his breast, placing Percy's hand right above his left nipple.

Percy lifted an eyebrow in question and Nico nodded, "Play with them?"

For the first time during this whole ordeal, Percy smirked, "All right."

He placed his other hand on Nico's other breast and started massaging them. Nico hadn't had them grabbed before, other than himself, so the feeling was new. It was erotic.

The sensation was intoxicating to Nico, and he took deep breaths. He would've moaned or whimpered if he wasn't so hellbent on holding in the noises. He swallowed, staring at Percy's abs. He'd be sure to kiss those, maybe leave some hickeys on a few, before the night was up.

Nico grabbed Percy's fingers and brought them to his nipples. Percy got the hint, and started pinching and pulling them. Nico moaned quietly, his voice shuddering. With a smile, Percy went a little harder, earning a hum and for Nico to close his eyes a bit slower. Nico scooted closer to Percy after a moment. 

He whispered, "Use your mouth."

Percy hesitated, his blush basically turning his face into a pink lady apple. He leaned down. Nico could feel his breath on his chest. He placed a hand on the back of Percy's head, feeling how soft his raven black hair truly was. It didn't look this soft when he had pomade in it, but it was the fairest thing he'd ever felt.

Percy gently put his lips over one of Nico's nipples making Nico gasp. He licked it, then swirled his tongue around it.

"Ah..." Nico moaned quietly. Percy knew he was doing it right when he heard that, so he kept doing it, giving little bites. Soon enough, Percy was sucking on Nico's breast, sending Nico into moans and whines.

"Baby..." Nico muttered breathily. "S-suck on them harder."

Percy obeyed, flipping between them every few minutes. Whatever one Percy wasn't sucking off, Nico was pinching with his other hand. With his head tossed back, he let Percy do his work, completely pleasured. He definitely enjoyed this more than he ever did with a flat chest.

After a while, Nico wanted more than just nipple-play. He pulled Percy's head back up and started kissing him aggressively, sucking on his tongue.

"Mm... baby," Percy muttered. "You're so pretty."

Nico bit Percy's lower lip, owning a loud moan. "You're perfect."

They continued like that for a moment. Once they pulled away, Percy dipped back down to Percy's chest.

"Wait," Nico said, taking deep breaths. "Can you... Do you want to..."

He hesitated, then pointed down at his crotch. His penis was hard and poking a tent through his sweatpants.

Percy smirked, "Okay. Anything for you."
