Percy was swimming through the lake at Camp Half-Blood. He had already done several underwater laps, and when he came up for a rest, he noticed a figure standing on the pier, waving its arm. He dived underwater and started swimming there, and about a minute later he popped up and climbed onto the pier. Standing on the edge was Rachel, in jeans covered with marker doodles with a light blue blouse. Her red hair was tied back into a ponytail, and she had an awkward grin on her face.

"Hey, Percy. We need to talk."

"About what?"

Rachel paused, looking around for anyone else.

"Well, remember when I was messing about with Thalia?"

"Yeah."

"Well, I got a vision that said the Host of the Oracle most remain neutral in any matters concerning the big three. So when I have sex with Thalia, it disturbed some ancient something or other. Well anyway, the point is that I need to go have sex with you and Nico to, well, put things in balance."

"And you're asking…?"

"I need you to get Nico, and both of you have sex with me." She said, twirling her hair shyly.

"So let me get this straight: You need to have a three-way with me and Nico?"

"Basically. I'll convince Nico, I'll get Chiron to let you off on Friday, you can head up to the cave and… you know."

"OK. I'm going to head back to swimming. You get that sorted."

Next Friday…

Percy and Nico walked up the cliff path to Rachel's cave. Nico was nervously playing with a Swiss army knife, while Percy was trying to calm him down.

"Dude, it's natural to be nervous. Just shut it and stop panicking."

"OK, OK. This is gonna be OK."

"Sex is never OK. It's always fantastic."

Percy reached the cave entrance. He swiped the curtains out of his way, walking inside. Lying on her bed was Rachel, wearing a transparent pink nightgown. Nico stopped as his eyes widened as soon as he entered. Percy noticed his dick was poking out of his pants, and smirked.

"Bit too eager there, mate."

Percy looked around the cave. Rachel had turned off all the lights and placed candles everywhere in an effort to make it erotic. He walked over to Rachel, who giggled nervously.

"Should we…?" She began.

Percy grabbed her sides and started French kissing her, sloshing his tongue around his mouth. He pulled off the nightgown and started squeezing her breasts tightly, before moving down her body and sucking her nipples, running her tongue over her soft tits.

"Come on, Nico. Join in."

Nico walked over, and starting rubbing her pussy lips and gently squeezing her ass. Rachel moaned, and Percy pulled off his pants and boxers, before pushing his cock between her moist lips in and out gently, before hormones took over and he started ramming his cock in and out of her mouth, forcing it as far in as he could manage, forcing her to gag slightly, spitting up on his shaft. Nico started sliding his index finger in and out of her pussy slowly, licking his lips. He started speeding up, before sliding in four of his fingers as fast as he could, causing Rachel to gag on Percy's cock. Nico took out his fingers and pulled down his pants and boxers, revealing a rock hard dick which he slowly pushed into Rachel's tight pussy. He slowly pushed it as far as he could, before shuddering ecstatically. He slowly took it out, before slowly picking up speed. Percy grabbed Rachel and picked her up, revealing her small, firm ass. He grabbed his cock and started shoved his dick straight up her tiny rosebud, shoving it in and out so fast Rachel started to whimper. He grabbed her ass to steady him with one hand, and pulled her hair back and took a sniff of her scent, before pulling her hair so tightly she whimpered in a mixture of pain and ecstasy . Nico gasped and pulled out. Rachel shuddered, and Percy shoved her onto the bed and started ramming his cock up her pussy, while Nico stepped in front of Rachel and cummed onto her face, long white strings of cum that covered her mouth, and she started licking up the cum as she moaned at the huge dick in her pussy. Percy sped up, and she moaned, her pussy juices dripping down onto Percy's dick. Percy groaned as he cummed, filling Rachel with warm, salty cum.

"Oh gods! That was fantastic." Rachel said, smiling.

Percy chuckled. "Well, it was a pretty fun way of restoring balance."

"Oh, that was bullshit. Restoring balance with sex? Please. I just wanted a three-way with you, and Nico's cute, so…"

Percy smiled playfully.

"Well, lying's bad, and liars need to be punished. Ready to punish her, Nico?"

Nico nodded, and Percy pinned Rachel down with his knees, and shoved his cock deep into Rachel's pussy. Nico crouched by him, and rammed his cock into Rachel's now stretching pussy. They rammed their dicks inside as fast as they could, causing Rachel to scream in ecstasy. Percy grabbed Rachel's ass and squeezed tightly, sticking a few of his fingers into her asshole and fingering her in unison with his thrusts. They sped up faster and faster, until they final felt Rachel's pussy tighten and cum over their dicks, causing Percy and Nico to groan, pulling out their cocks and cumming over Rachel. Percy's string of cum hit Rachel's cheek and covered her hair, while Nico cummed over her stomach. Rachel groaned, and Percy started licking up her pussy juices from her snatch, and Rachel scraped the cum off her hair and stomach and licked it up. After Pussy finished eating out her cunt, He put his clothes back on and smiled.

"We really need to do this more often."

Rachel smiled, panting.

"If we did… I'd never be able to walk right again."

Percy smiled, and began walking back to the cabins.
