The anticipation of what was coming to Piper bubbled in the room in all of two seconds. Jason scoffed terribly trying to makeover an unmistakable desire to burst out laughing. Piper seemed to have been holding her breath. She let it all out through her mouth, her pink moist lips blowing in a soft way that added to the mood being felt around the room.

"Hmm…" Piper wiggled around playfully as she thought. "Truth!

Leo groaned. All the other guys (and Annabeth) looked disappointed. Tyson clapped loudly three times. "How many guys have you blown?" Rachel asked.

"Twelve. Annabeth?" she said quickly as Jason drew in an audibly deep breath.

"Dare," Percy's girl said without hesitation.

"Shake your ass stripper style in Tyson's face," Piper dared. "Lose your shorts while you're doing it."

Percy scoffed and Tyson looked confused. Annabeth blinked a multitude of times, like, what-the-hell did-you-just-say? But picked herself off the ground nonetheless and pulled down her small white shorts revealing a pink thong that hardly hid her clit. She walked slowly over to Tyson, who had frozen still like stone. He might not have been prepared for what was going on here tonight.

"Hey Percy's baby brother," Annabeth giggled. Without further encouragement from the others, she turned back around, bending all the way down so her ass was right in his face, and began shaking it crazy, so bad that it was almost merely a blur. Her thong was nearly coming off and some of her admirers sitting next to Tyson (Charlie and Frank) could catch small glimpses of her anus and clit when it shook too wildly. Some of the others hooped and hollered and Percy tried looking away, but found he couldn't. He didn't even know his girl could shake her ass like that. Poor Tyson…

"Daaaamn," Rachel said.

"Oh, fuck" Piper agreed. Then Annabeth abruptly stopped and straightened back up. Tyson had a boner beginning to lift up.

"Well, I think that's enough," she said. After many vigorous nods she giggled and pointed at Hazel.

"Truth or dare?" Hazel looked scared, but still said-

"Dare."

"Lick some Tequila off our hosts' shaved pussy."

Finally! Percy thought. Annabeth comes through! He mentally arm pumped. Seeing Annabeth's ass shaking was great, probably enough for the other guys, but he got in that two or three times a day. A little variety never hurt anybody.

"Oh my," Hazel said looking to Rachel who was licking her lips. She dashed to a room out of their sights and was back in no time with a bottle of Cuervo. She got out of her shorts, letting the boys drool over the sight of her in those red lacy panties. She then looked around at them until she found Percy, turned her ass towards him and then, with her thumbs, peeled her thong down slowly. She bended over while doing so and looked back at him seductively making sure he was getting a good view of everything. As her anus and her bright pink vulva came into view, Percy put a large hand over his crotch to hide the growing erection. Annabeth raised an eyebrow.

"Hurry up and do it girls." She said cooly.

Rachel laid down flat on the rug as Silena took the honors of pouring just under a shots worth of tequila on her crotch area. Piper and Thalia were fanning themselves with their hands. Connor and Travis already had hard-ons that Katie was eyeing.

Hazel lowered her head above Rachel's area and licked it up with one big, long slurp. It must have tasted nice, because then she lowered her head a little bit more and touched her tongue down on Rachel's clit causing her to moan. She twirled it around, licking around and slurping the wetness coming from Rachel's pussy.

"Ooh!" Hazel started. Someone had just smacked her ass. She turned to see Katie looking guilty. "Sorry," she murmured. "It just got pretty hot."

Hazel laughed and got up ("but— wait— what?" Rachel groaned). "Connor, truth or dare?" "Truth," Connor answered. Travis tutted.

"Who's got the best, and fuckable ass of them all? And of them all, I do mean of us in this room." "Don't say some gay shit," Travis muttered. Everyone laughed, but Connor swelled up dignified.

"Thalia," he said. Hard to argue with that one. She easily had the best and bubbly ass in the group. Thalia bit her lower lip and looked over to Connor, making eye contact that they held for a while. Those sky blue eyes were sexy as fuck.

"Juniper," he called. She sat squirming around for a few seconds before she timidly called out, "Dare." Grover's shoulders slumped.

"I dare you to let Nico spank your ass with the flat of his blade," Connor snickered.

"Oh," Juniper blushed a deep green, but stood up accepting nonetheless, walked to the center of the group's circle and proceeded to get down on her knees in a face-down-ass-up position so everyone would have a better view of the goods.

"Let us see that ass!" Travis catcalled. Percy snorted as everyone else, Annabeth and Rachel the loudest among them, wooted.

"Whoo, yeah!" Annabeth cheered.

"Shake it baby!" Selena hollered.

Juniper obliged and, pulling down her cotton white shorts revealing her green ass barely hidden by a light brown shoelace g-string, and gave it a little wiggle. Nico nodded his head slowly as he summoned his sword magically at hand through the darkness. Juniper looked back at it fearfully. The reason it was such a becoming dare wasn't just because of the actual act, but also because all nature spirits feared the River Styx and Stygian iron. She was showing her guts.

"Ready?" Nico asked. Juniper nodded. Pulling back the blade, he swung forward and smacked her bare ass with a sharp thwap!

"Ooh!" Juniper jumped. Nico reached out with his left hand to grab the back of her head to hold it down.

"Stay still," he hissed, and thwaped her again, and again.

"Ah! Ooh! Oh my, this is— ahh!" Juniped cried out silently, trying to take each hit. Her butt was now pretty bruised, or it was a little deeper of a green than the rest of her body. With a final thwap that was a little harder than the rest of them, Nico looked up, grinning. Everyone was nodding appreciatively, which meant the job was good and done. He walked back over to his spot in the circle and sat down, letting the sword disappear into darkness.

Juniper whined silently, not even bothering to get up. She crawled with her head down, butt still straight up in the air so everyone could see her ass cheeks swaying back and forth sexily as she crawled. Not knowing where she was headed, she wound up in between Jason and Percy.

"Aww, let me help you out there," Jason said reaching out and rubbing her right ass cheek softly. Piper huffed as Percy reached out and did the same with her left cheek. Jason looked to Piper.

"What babe?" He said sprightly. "Only lending a helping hand." She rolled her eyes. Beside her, Annabeth touched her wet area thinking of her boyfriend dominating the girl whose ass he was handling. It was hot to her.

Katie and Selena were likewise squirming and playing with themselves friskily. Katie liked Travis, and Selena liked Charlie… But Jason was the handsome son of Zeus. And Percy was the strongest demigod alive. He had long since become a man. And they were both, oh, so sexy. They were each the height of what cool could be in the demigod world. Seeing them both play around with Juniper while Grover was looking on pouty like some Brazzers porno was about to go on was enough to make any girl wet. They continued rubbing her butt and squeezing it for a little while more before they stopped to let the game continue. By then, the girls couldn't stand it. Selena was sitting Indian-style rubbing her foot against her crotch.

"Who's next?" Charlie called. He seemed totally calm and cool, but Tyson's face was a deep red and his crotch was— whoa. How big was that Cyclops?!

"Hosts' choice, since Juniper is still out of it" Annabeth said.

Rachel hummed to herself as she looked around the anxious group. Her eyes laid on Percy and Jason themselves, who had made Juniper sit in between them with her legs widely spread, and were helping themselves to rubbing her inner thighs, causing her to moan softly. They grinned and high fived each, laughing openly.

Oh, best buddies aren't y'all? Rachel thought to herself. Time to put the ultimate duo through a trial. So-

"Percy" she said. He looked up and shrugged cockily.

"Dare." Just as Rachel hoped.

"Fuck Jason's sister," she said. Jason gave a start and stared at her. Percy, however, wasn't looking quite so shocked. He looked at Thalia, locking eyes with her. It couldn't have been plainer that she wanted it badly.

"Where at?" Percy asked out loud not breaking eye contact with her.

"Right here in the middle," Rachel pointed. "Be our fucking entertainment!"

"C'mon man, don't do this.." Jason muttered, not looking at his friend. "Pussy out," he pleaded.

Percy ignored him and walked over to the middle, meeting Thalia there who looked pretty thrilled. They started checking each other out, up and down. Thalia was neck-and-neck with Silena for the Best Body Award. She was slightly thicker than Silena's petite body, but in a good way, Percy thought. Best ass of the group, probably a D-cup size chest and— oh god. She wasn't wearing a bra. How hadn't he noticed it yet? As she walked her tits bounced around and jiggled in the front through her tiny blue tank top. She also wore black athletic shorts. Good outfit, for a warm summer night of teasing boys.

She smiled. "Hey."

"Hi," Percy grinned and nodded.

"I do not want to see my best friend fuck my sister," Jason said loudly determinedly looking at the cave ceiling.

"Everyone else does, so keeping looking up and shut up! You're ruining this for us," Connor called back. Everyone laughed. Annabeth was biting her lower lip, looking wildly excited at Percy and Thalia.

"Lay down," Thalia told Percy. He did so, then Thalia sat down on top of his waist and leaned down and kissed him. Quickly, their tongues were in each other's mouths and Thaliaa started grinding on him, rubbing their areas onto each other. His cock was already erecting.

Percy grabbed her ass roughly and smacked it. Thalia moaned into his mouth making him even harder. Grabbing her ass cheeks and shaking them vigorously like he owned them turned Thalia on even more as she took care to rub her tits along his chest as she continued grinding. Percy took a hand to her lower back and started lifting her shirt up, when-

"Whoa!" He heard from everyone around him simultaneously.

"What? No way!" Leo said distinctively. Percy extracted his face from Thalias, who was smirking. "What? What is it?" he asked looking at the group.

"Dude!" Charlie exclaimed. "Look!"

Thalia sat up on him, allowing Percy to rise up as well, so he wheeled his torso around her to check out what was up. She had a lower back tattoo. Two ravens around each other forming a heart, surrounded by some rose-thorns. Even Jason had looked.

"A Tramp Stamp?" he croaked.

Silena swallowed. "That's so hot."

Staring at it for a few moments, Percy became fully erect. His dick, like having a mind of its own, was trying to push through his shorts and make its way into Thalias. Had they already been bottomless, they'd be fucking. She felt it and looked down at him.

"How do you want me?" She asked.

"Like this first," he said and yanked her tank top off with one move and buried his face in her bouncing chest.

"Daaaamn Jason, he's doing that to your sister." Leo instigated. Jason was ignoring him and staring back up at the ceiling.

"Stand up," Percy demanded. She did as she was told and he yanked her bottoms down, so everyone was now getting a good look at either her bare, globe-shaped ass, or her shaven pussy. Percy hurriedly took his shirt off and pulled his shorts off too, kicking them to the side. Now all the other girls (and Nico) were staring at his cock, rising at least nine inches into the air beneath Thalia's vagina.

"Sit," Percy told her. As she did, she reached under and grabbed his long dick, positioning it at her wet entrance. And then she sat all the way down.

"Ahhh shit, Percy!" She gasped. "It's soo big!" But she had already started going up and down, riding him. Percy was rocking with her, and slapped her ass some more, energizing her to go wilder and faster. She was really losing herself.

"Unh! Unh! Unh! Aahhh!" She moaned loudly. Slapping her ass once more, Percy pulled her to the ground on her side and laid behind her, also on his side. He positioned her cock at her entrance, then shoved it in. Thalia was sorta tight.

He began fucking her again. Each thrust sent a popping smack, smack, smack echo across the cave that Jason was finding hard to ignore. Everyone was watching in silence. Percy was huffing and puffing, Thalia was gasping and moaning, her tits bouncing everywhere as he pounded her. Then suddenly, he stopped and pulled out. His cock was pulsating as he pulled it back and pushed his dickhead to Thalia's ass crack.

"Oh my gods Percy," Thalia swooned. She reached behind her to pull up her top ass cheek, exposing her anus to allow him to get it in.

As he shoved it in inch by inch, she took it with quiet moaning. This wasn't all that new to her. Anal was her thing, but she hardly ever did it with anyone so big.

"Ahh, fuck man! He's fucking my asshole!" She moaned loudly. Everyone 'whooped' and cheered and hollered. Jason groaned.

Percy started thrusting hard, now hitting her ass with a smack each time. All the way in, all the way out. All the way in, all the way out. He loved the reaction he was getting from his gang and from her, Faster and faster, until-

"I'm going to cum! Oh, shit! I'm gonna cum!" Thalia cried. A moment later her muscles tightened, including her ass around Percy's cock, as she came all over her own thighs and on the floor.

"Fuck yeah!" Percy growled and started thrusting harder as Thalia was now nothing more than a rag doll being viciously plowed. As he got closer and closer too, he groaned loudly and pulled out, got up and stood over Thalia who simply laid flat on her back now and opened her mouth wide, waiting happily for the load to come.

Percy beat his dick off for a few more seconds, then came, almost violently, shooting huge loads all over Thalia's face and in her mouth. He stood up over her, sweaty and panting.

"Daaamn," Annabeth said delightedly. All the girls were staring at Percy's well-hung dick. Silena was fanning herself.

"That was so hot you guys!"

Rachel clapped her hands together as Percy started putting his clothes back on. Jason looked stern. "Okaay guys, who's next?"
