Piper was bored out of her mind on the deck of the Argo II. Frank and Percy went off to the Atlanta aquarium to chase a clue, and she was assigned lookout. It was a boring job, but at least it didn't need a lot of work. She thought. She tried to think of ways to entertain herself, but none came to her. That is, until she saw Percy come back with Frank and Coach Hedge.

She remembered when she gave Percy a blowjob in New Rome. At the time she was hoping to go all the way, but they were interrupted by the eidolon attack. Today might be her chance to finish that.

'Heyyy Guys!' She said, as they came back. 'How was it?'

'Not good.' Percy replied. 'We got trapped in a fish tank.'

'But we were able to get some information.' Frank added. 'Apparently there's an important map in the city of Charleston related to the Mark of Athena.'

'That sounds useful. Go down and tell Annabeth, I think she'll understand it the most.' Piper said, trying to get rid of him. 'Percy will tell me what happened.'

'Sure.' Frank promptly left.

'Okay...' Percy started. 'So apparently these two gods are running the aquarium-'

'I don't care about that, it was just an excuse.' She shrugged him off.

'An excuse for what?' He sounded offended.

'Come with me.' Piper took him down to the lower deck of the ship, where thankfully, Frank seemed to have gone. She got in her room, and quickly closed then locked the door once Percy followed her in.

'What's this about?' Percy tried getting her to ask again, but she was already undressing.

'I just want to be able to actually have your cock in me this time, if that's okay with you.' She stated non-chalantly. She waited for Percy's answer, but wasn't seem to be getting any. She realized he was staring at her, now already completely naked, stunned.

'You just fucked Annabeth last night, right? I assumed if I waited til after that you would be more comfortable, but if not I can just-'

'No, no no!' Percy stopped her, 'I was only a bit surprised by the bluntness.' He started to undo his belt and pulled down his pants and boxers.

'Good, I'd hate to have to wait more.' She stroked Percy's dick as he took off his shirt, before realizing he was staring at her tits. 'You can have a go, you know. I won't mind.'

'Sorry, it's cause I didn't see them last time.'

'Well, here you go!' She giggled, using her free hand to push his head between her boobs as she continued stroking him. He was considerably taller than her, so he had to bend down a bit to reach her, giving her a good view of his arched back.

Percy, though, wasted no time as he began motor-boating Piper's C-cups. She closed her eyes as he shook his head from side to side, occasionally kissing or licking her skin. She gasped, though, when he used his fingers to pinch her nipples. 'Oh! Percy!' She squealed, before pulling away. 'I don't care anymore. I need you to fuck me now' She said, lying down on her bed, pulling her legs to the side with her hands. With her legs off to the side, her pussy was now exposed at the edge of the bed, inviting Percy.

Percy didn't hesitate. He dove into Piper, fucking her madly.

'Shit, you're tight.' He commented, trying to savor the feeling.

'FUCK YES!' Piper screamed, barely hearing him, enjoying Percy's cock to the fullest. 'OH FUCK ITS SO BIG!'

'You like that?' Percy teased

'Yesss!' Piper moaned. Percy spanked her ass.

'You enjoy having my dick in your cunt?'

'Yes! I love it!' She yelled. 'I love how your massive cock creates friction against my pussy! I love how my body shakes every time you thrust!'

'Am I better than Jason?' He asked, holding her neck.

'Yes Percy!' She gurgled. 'Jason can't fuck me like this!'

'That's what I thought.' He smiled. He pulled out of Piper, and took her legs out of her hands.

'Wha-?' Piper tried to ask, but Percy flipped her around so that her face was buried in the sheets, and her ass was perked up, facing him.

'I'm gonna show you how sex with me really feels.' He burrowed his hand under the covers, until he found Piper's pussy. He played around, fingering her until he had enough of her juices on his fingers. He took his hand out and slathered Piper's own cum and juices into her asshole. He spread her asscheeks to the side, and slowly began stuffing his dick into Piper's ass.

'OHHHHH...' Piper mewled, feeling herself getting filled up. 'FUCK! FUCK! FUCK!' She screamed into the covers, though Percy wasn't even fully in yet. He dove further, until the tip of his cock couldn't go in any more. He started pumping up and down her ass, while Piper screamed as she felt her butt burning from the sensation. Percy climbed up into the bed so that he was on top of her, adding more weight into his thrusts, and using his hands to push Piper's head deeper into the covers.

In the end, Piper came on her bed, tensing up as she released all her cum. Feeling the change, Percy pulled out as well, and turned Piper around once more. She watched as he stroked his cock in front of her a few times, until his cum shot out of his dick as well and landed on her face. Seeing Piper's face covered in his cum, he kissed her one last time.

'Next time, I'm bringing in Annabeth to help.' He whispered in her ear, making her shiver.
