Percy and Annabeth were spending a day at the beach. Percy was laying on a beach towel with Annabeth curled up at his side.
"Let's go for a swim," he suggested.
"Alright," she agreed. She watched as her boyfriend lifted his shirt above his head, revealing a bare and very, very muscular chest. All that camp training really paid off. She took off her orange Camp Half-Blood T-shirt, leaving her in only a pale blue bikini. He stared at her hungrily, took her hand, and led her into the ocean.
They lingered in the shallow part until Percy grabbed her face and pulled her under.
Annabeth found herself laying against a bubble in the middle of the ocean with a shirtless Percy onto of her, smiling mischievously. He brought his mouth down onto her's. His one hand was on her hip and slowly, sensually, glided up to her bare waist, her breast. She moaned into his mouth and she felt him smile.
"I can do more," he whispered.
They struggled to get their bathing suits off, a difficult task inside a bubble. She worried it would pop but Percy assured her it wouldn't.
He leaned his naked Annabeth down and dragged his tongue along one of her nipples. With her legs wrapped around his waist and her hands in his hair, she let out a sound of bliss. Her noises made him harder and his anticipation became too great. Grabbing a handful of her long, blonde hair, he slowly slid inside her. He continued to thrust and make Annabeth scream her beloved's name, "Percy, Percy."
She dug her nails into his back as she climaxed and he came inside her. Annabeth was dully aware of the fish swimming around them but didn't mind the spectators. Percy lay beside her, pulling her closer to him. Their legs intertwined.
They lay like that for the rest of the afternoon.
