Percy had Nico bent over the bed, face in a pillow.

Percy started by smacking Nico's ass, hard. He left a red mark and Nico gasped, "Fuck! You asshole!"

Percy hit harder, "What's my name?"

Nico didn't respond, earning another smack. He moaned into his pillow, "Mister..."

Percy leaned down, "That's right."

He kissed trails down Nico's back, then bent down, kissing down Nico's ass-cheeks. He was going to go to his legs, but Nico started moaning like crazy.

"A-ah... Mister... Oh, Mister..." he moaned into the pillow, trying his best not to glance back.

Percy smirked, leaving a little bite on Nico's ass.

"Percy!" Nico yelped.

Percy got up, pulling away, "What's that now?"

Nico caught his breath, "No-no, don't stop.."

"What's my name?" Percy reminded.

Nico glanced back, smirking mischeviously, "Percy...-"

Percy smacked his ass where there was still wetness from the kisses. Nico jumped, "Baby..."

Percy smacked again, and Nico didn't respond but looked back. Percy went to smack again and Nico yelped "Mister!" but Percy smirked. Nico realized he hadn't actually smacked him that third time, he just had him trained well.

Before Nico could playfully glare, Percy bent down again, leaving a few more kisses. After a minute, he started biting, leaving little marks all over. Nico was going crazy, leaning back and gripping the bedsheets. Percy had no idea Nico would enjoy this kind of thing this much, but now that he knew, he'd do it all the time for his boyfriend.

After another few minutes, Percy started leaving a hickey.

Nico couldn't control himself, "Ah! Mi-mister, ah... Fuck... Fuck, I love you, fuck... Ah..." Moan after moan, hearing his cries just fueled Percy.

Once the hickey was gun he stood back up, smacking it. Nico jumped, whining into his pillow.

"What do you want, my prince?" Percy asked in a low grumble.

"You..." Nico responded, needing Percy closer.

"How do you need me, my prince?" Percy posed.

"In me," Nico said all too quickly.

"As you wish," Percy responded, bending back down.

Nico tightened his knees to prepare himself, and Percy started tongue-ing Nico's ass. Percy sucked on the top muscle, knowing it'd relax Nico more than poppers.

Nico couldn't hold in the moments, "Ah... Percy...!"

Percy smacked Nico's ass as he continued, unwavering.

"Mister, please!" Nico bit his lip, tugging the sheets under his chest. "Oh, yes..!"

When Percy was finished, Nico was panting and sweaty, face beat red. He looked back at Percy, "Why are you stopping?"

Percy smirked, squeezing Nico's ass as he responded, earning a whimper, "Didn't you say you wanted me in you, my prince?"

Nico smiled, "Yes, please, mister..."

"Good," Percy smirked, taking it out. "Because I keep my promises."
