Annabeth sat across from Piper, the noise of the busy coffeeshop surrounding them as they discussed their arrangements. The afternoon sun was shining in, revealing Annabeth in a New Rome swim team hoodie, courtesy of Percy, and Piper who was wearing very little save for shorts and a tank top.

The two girls had taken vastly different paths to get what they wanted. Annabeth was attending New Rome with Percy, which she enjoyed very much since she had basically gushed about her major to everyone who asked. Piper on the other hand went down a route of trying to find her identity, that included breaking up with Jason and dating a girl named Shel.

Annabeth had never met Shel before, she only knew of her from what Piper told her. She doubted she'd ever meet her since Percy and her were planning to move back to New York to help out at camp once they were done with getting their degrees.

Piper took a sip of her hot chocolate before shaking her head, "Run me through this again. You want me to do what?"

Annabeth leaned forward, a mischievous look in her eyes, "You heard me the first time, McLean."

"I know I did." The daughter of Aphrodite responded, "I just want to make sure I heard you correctly."

"Fine. Have it your way." Annabeth said, "It's simple, I want to get Percy a birthday gift, one that he's never gotten before. I want you to help me out here."

"You said you wanted a threesome!" Piper said.

"Exactly." She replied, "The only threesome Percy's ever had was with me and Rachel. Rachel is hot and all, but I know you have tricks up your sleeve that'll make him go wild. You're a daughter of Aphrodite, sex is one of your domains."

"Annabeth, I can't do that." Piper said, "I have a girlfriend. If she found out, she'd never forgive me."

"No one is going to find out." Annabeth said, "Me and Percy won't tell anyone. Our apartment is soundproof and no one knows you so the chance of Shel finding out is low as fuck."

Piper sighed, when Annabeth had called her for a little chat, she hadn't expected this. The daughter of Athena wanted to give Percy a threesome for his birthday, but this time she'd be included. At first, she told Annabeth to just find Rachel, but she said it wouldn't do. Apparently she wanted someone skilled in the art of sex.

"How about this?" Piper sat forward, "If I say a number and Percy's dick is below it, then the deal is off."

"Deal." Annabeth said, "Say a number."

"Seven." Piper said confidently.

Annabeth clicked her teeth and smiled, "Should've thought about it, girl. Percy's a nine."

Piper's eyes widened. Not only did she realize that she was now basically locked in on having a threesome with Percy and Annabeth, but she also had never known that Percy was that…endowed. She thought Jason was big, he was seven inches, give or take. Percy was enormous.

"Okay, a deal's a deal." Piper said in defeat, "What's the plan?"

Annabeth rubbed her hands together with a devious smile, "Alright. Percy has a afternoon class tomorrow, he shouldn't be home until 5. I don't have classes, so you can come over tomorrow."

"Isn't Percy's birthday this Saturday? Tomorrow is Friday." Piper pointed out.

"Yeah, but Percy wants to spend his birthday with just me. We just got a new camera and if I had to guess, he wants to film more porn." Annabeth explained.

The daughter of Aphrodite shook her head, "You two are nuts. I can't believe I'm doing this."

Ω

Percy was exhausted as he made his way through the halls of the apartment and towards his suite's door. He had just gotten out of his fundamentals of marine engineering class and his brain was fried. He was keeping up a low A in the class, but mainly because he studied his butt off.

Yet now it was Friday, and all the numbers and formulas were far behind him. This weekend was looking to be an amazing one. First, he'd spend all of Saturday with Annabeth, then on Sunday he'd sleep in. He was more than excited at the prospect of being able to relax.

The last thing he was expecting when he walked into the apartment suite however, was for Annabeth and Piper to be waiting for him. Normally, he'd be surprised and happy to see them but now he was surprised and confused. He wasn't surprised to see Annabeth, she lived with him. He was a little surprised to see Piper, she rarely visited. Yet the main reason for his confusion and surprise was their choice of clothing or rather, their lack of.

Annabeth was all but naked, save for a thin string bra and panties. Her formerly tan skin was a creamy color, thanks to the fact she spent more time indoors nowadays studying rather than training at camp. Her hair was free and flowing down her shoulders, the curls wild and unrestrained by anything.

Piper was actually naked. She wasn't wearing a bra or panties. Her multicolored eyes made her look mystical. Her hair was neater than Annabeth's, yet it was just as long. Her body was nothing to laugh at. Her breasts were about the same size as Annabeth's, maybe a little bigger. She was slim, she definitely had kept her figure despite not being at camp year-round.

"W-what the fuck?" Percy stammered.

"Happy early birthday, Percy." Piper said with a blushing smile.

Percy looked between the two girls, his face morphing between confusion and shock.

"You mind closing the door, Seaweed Brain?" Annabeth asked.

Percy looked behind him and realized the door to their apartment was still open. He quickly shut it in horror, he didn't need his neighbors seeing two very attractive naked women in his apartment, rumors circulated quickly in their apartment complex.

He looked back towards the girls, who were still staring at him. He inched forward cautiously, he wasn't sure what to do. When he, Rachel, and Annabeth had their threesomes, the girls would often warn him in advance, this was by complete surprise.

Annabeth glanced over at Piper and nodded. At once, they both rushed him. Percy hated to admit it, but he let out a terrified shriek as Piper grabbed his white collared shirt and unbuttoned it at lightning speed. Annabeth made short work of his jeans and boxers, yanking them off of him in a matter of a minute.

"Oh, gods!" Percy cried out as Piper attached her mouth to his neck while Annabeth crammed his cock in her mouth.

Piper was nibbling on Percy's neck, making sure to leave a hickey. She ran her hands along his abs and chest, enjoying the feeling of his muscles contracting under her touch. Part of her was happy that she took this offer, Percy was easily one of the best looking guys she'd ever seen, he gave Jason a run for his money.

Annabeth meanwhile let out nasty sucking noises as she bobbed her head back and forth. She grabbed Percy's hips to stabilize him while she sucked him off. She would nearly spit him out before suddenly deepthroating him, his tip hitting the back of her throat. She had a hungry gaze in her eyes as she went ahead with her blowjob.

Piper pulled her mouth of his neck and started whispering seductively in Percy's ear. "You know, I'm kind of jealous that Annabeth has all the dick, I want a turn." She whispered before nibbling on his earlobe.

"Y-you'll get your t-turn." Percy struggled to get out as Annabeth gave him a particularly hard suck.

Piper let out a satisfied growl, "Good, that's what I wanted to hear." She looked down at Annabeth, "Hurry up, girl, I'm trying to fuck."

Annabeth glared at her though she didn't take it seriously. She just didn't look all that threatening with Percy's dick shoved in her mouth.

As minutes passed by, Piper sighed and walked around before getting behind Annabeth. She knelt down and pulled her hips back a little, running her hands over her ass. Annabeth had a somewhat apprehensive look in her eyes as she probably wondered what she was up to.

Percy watched as Piper started humping Annabeth. He'd be lying if he said it wasn't one of the hottest things he'd ever seen.

"You have an awesome ass, Annabeth." Piper said with approval, "I see why a lot of guys back at camp rate you a ten out of ten."

Percy normally would've been pretty angry at the idea of a bunch of guys rating Annabeth yet he couldn't d anything but moan as he erupted into Annabeth's mouth. Each spurt from his dick was met by a swallow from Annabeth.

Annabeth released Percy's dick and wiped her lips. She looked over her shoulder at Piper, "Can you stop humping me now? I'm done."

Piper smiled, "About time." She got to her feet and motioned with her hand for Percy to follow her, "Let's go to your bedroom."

Percy quickly followed after her, watching her ass as she walked. Her ass was definitely bigger than Annabeth's though it jiggled more. Annabeth's ass had that perfect blend of firmness and jiggle, Piper's didn't. Regardless, it still caused Percy to be as hard as a rock.

Percy couldn't take it anymore, he needed to fuck someone or something, he didn't care if he had to fuck the couch, he needed to do something. He grabbed Piper's hips and turned her so she bent over the couch. The daughter of Aphrodite let out a cry of surprise before moaning when Percy pushed into her.

"Percy, you absolute dog!" Annabeth laughed.

Percy ignored her, her gripped Piper's ass cheeks, squeezing and groping the soft globes in his hands. He smooshed them together before spreading them apart. He did this a few more times before releasing her ass all together and grabbing her hips. He pulled back and thrusted forward.

Piper let out a loud moan. She wasn't a virgin, Jason had taken care of that a long time ago, so she didn't feel any pain when it came to Percy's cock probing her insides. She did feel full though, she'd never felt so full before. Her whole body felt like it was wrapped around the enormous length buried inside her.

"Damn, you're tight!" Percy grunted as he fucked Piper over the couch.

"You're huge." Piper let out in a breathy moan, "Keep moving your hips just like that."

Percy had no idea where Annabeth went, at least until he saw her emerge from their bedroom, a camera in her hands. She smiled at him as she pressed the record button. She started filming them, kneeling a few times to get a better view.

Piper gripped the back of the couch as hard as she could, her tan knuckles turning a shade of white. She looked back at Percy but her eyes locked onto Annabeth with the camera.

"Your boyfriend's cock is so nice!" She moaned at her, "You're so fucking lucky."

"Consider yourself lucky that I'm even sharing." Annabeth retorted.

"Mmhmm." Piper hummed as she started pushing her hips back towards Percy.

Percy's hips smacked against Piper's ass, creating a clapping sound that could be heard throughout the room. His balls slapped against her wide and spread lips, his length being covered in a clear slick each time it pulled back.

"Fuck, I'm going to cum." Piper warned.

Annabeth quickly shuffled over and started recording Piper's face. The daughter of Aphrodite flashed the camera a sultry smile before her face changed completely. Her mouth gaped open and she squeezed her eyes shut before moaning loudly. Percy let out a groan from behind her as he too started cumming.

A smile spread across Annabeth's face, Piper was yet another girl who had now experienced being filled by Percy. In terms of score, Annabeth had been filled up more times than Rachel and Piper combined, thought it wasn't fair since she had a head start. Rachel tried to catch up but eventually she gave up, she just didn't have the godly stamina to handle being fucked multiple times by Percy.

"Give me the camera." Piper said to Annabeth, "It's your turn."

"Let me show you how it's done." Annabeth said cockily as she handed off the camera to Piper, who instantly started recording.

Annabeth walked over to Percy and gave him a dazzling smile as she wrapped her arms around his neck. She jumped up and wrapped her legs around his waist, locking her ankles together to make sure she didn't fall, though Percy made sure that wasn't going to happen since he was holding her up by her thighs.

"You ready?" He asked.

"Fuck me, Seaweed Brain." Annabeth ordered.

Percy reached between them with one hand and aimed himself at her core before pushing into her. Annabeth let out a girlish moan, one that caused her to blush and Piper to laugh. The daughter of Athena's toes curled as Percy started to thrust in and out of her.

Piper walked over and started recording the two, making sure to get a nice view of Annabeth's ass before showing what was going on between the two, Percy's dick spreading Annabeth's pussy so wide that it almost looked painful.

"Fuck." Annabeth sighed as she tried to keep her composure.

"Don't tell me you're about to give up already, Annabeth!" Piper taunted, "If you cum already, I'll never let you live it down."

Annabeth gritted her teeth as she tried her hardest not to orgasm. Percy didn't make that easy since he started thrusting into her faster and harder than before. Their thighs slapped together as Percy took her.

Annabeth thought this was totally unfair. To Piper, Percy was just a nice fuck. Yet to her, he was more than that. Each time they had sex felt like she was truly one with him. She'd only ever had Percy inside her, the thought that her pussy was entirely his to fuck drove her mad. The intimacy of it all was enough to push her over the edge.

"One more minute and you beat me!" Piper chimed.

Annabeth bit her lip and moaned, this was getting very difficult. Her head pounded and her heart seemed to beat out of control. Her head went back and forth as Percy started fucking her as hard as he could, he let out grunts and groans as he pounded her.

Slap! Slap! Slap!

The noises were going to make Annabeth scream her lungs out. She wasn't going to make it, she was sure of that.

This was possibly one of the hardest things she'd ever had to do, and that was saying a lot. One time at camp, Annabeth had challenged Clarisse to see who could hold the longest plank and by the end of it, both girls were shaking. Annabeth only won because she weighed less, and she'd won by seconds.

"Ten seconds!" Piper called.

"Fuck, fuck, I'm going to cum!" Annabeth started shouting, "It's too much!"

"Don't you dare, Chase!" Piper yelled.

Annabeth's response was a string of moans and cries. She counted down ten seconds in her head. Each second felt like an hour. Her body felt like it was about to burn up. She closed her eyes and braced herself for her long-delayed orgasm.

"And you've beaten me!" Piper cheered.

Annabeth screamed as she came. Her vision went white a few times as she came all over Percy's cock. She thrashed around, barely holding on. Percy struggled to keep her steady and he'd even stopped fucking her for a moment to make sure she was okay.

Annabeth felt amazing. She felt like she was in Elysium. Her orgasm hit her like a freight train but had now started to flow over her like water in a shower. Her vagina clenched and unclenched around Percy.

"You okay?" Percy asked her.

Annabeth looked over at Piper, who was sporting a taunting smile. Piper had already taken a load from Percy, now it was her turn. She wouldn't chicken out now.

"Cum in me, Percy." She said.

Percy shrugged before resuming his thrusting from earlier. Annabeth hugged him tightly as she started to take in the feeling of being fucked after a orgasm, a experience she'd felt plenty of times. She could hear the squelching coming from between them as Percy worked on blowing his load.

It was a minute later when Percy groaned and buried himself as deep as he could into Annabeth. Semen shot out of his tip and into the deepest recesses of Annabeth's pussy. She let out a moan as she got filled, her eyes never leaving the camera as it filmed on.

Percy let go of her at last, his cock sliding out of her, followed by a thick trail of his seed. Piper made sure to record that before stopping the recording.

She smiled at her two friends, "That was amazing. I'm down for a few more rounds if you guys are."

Annabeth and Percy smirked at each other.

"Get over here."

A/N: And this is the final bonus scene. Now i can start to work on my more serious stories. Hope you all enjoyed this! This idea wasn't my original idea, but it was suggested to me by a guest in the reviews so i figured i'd write it.
