Piper's Betrayal

Previously:

"AAAAAAAAHHHHHHHHH! FFFFFFUUUUUUCCCCKCKKKKKKKK!" I groaned out. I felt my nuts twist as the first rocket-load of jizz fired out of me, exploding deep inside my mother's waiting cunt. "UGHHH! GOD! YES!" without my notice, at the same time, a purple glow softly lit the room, encircling my bed as waves of magic rushed at me and sally.

"FUCK! I feel it! YES! YES! AHHHHHH!" Sally screamed out as I exploded inside her. Her pussy tightened around me. "I'M CCCCCUUUUUMMMMMMMMMIIINNNNNNGGGG! YES! YYYYYEEEEEEEEEESSSSSSSSS! FUUUUHHHHHHH! FUCK! FUCK! YYYYEEEEEEEEEESSSSSSSSSSS!"

As my throbbing cock fired off jet after jet of thick cum deep inside her, her pussy locked around my cock, quivering as she came. I felt her juices colliding with my shaft as my dick exploded a gallon of sticky cum balls deep inside her. Our bodies were clinging to each other as I kept pumping into her, trying to bury as much cum as I could deep inside her.

As my nuts twisted and my cock pulsed, I was seeing stars. I was on a new plane of pleasure as I came in my mom's pussy, having the biggest orgasm of my life. My hips drove into her roughly as my body jerked in pleasure as my cock finally found release. I just kept cumming, firing off huge bands of cum inside of her, filling her up.

"There's so much! Oh Gods! Yes!" Mom cried out from beneath me as squealed with pleasure. It felt like it went on and on, never ending. I don't know how long it lasted, but eventually I came down from my high. After one last mind numbing jerk of pleasure, I fell off of her, panting for breath as I rolled off of her and onto my back. Mom stayed on her belly, curling up slightly as she tried to recover from her own high.

We stayed like this for a few minutes, frozen in place. I was utterly exhausted. I had just had the craziest, most fucked up sex of my life, and I had done it with my own mother. It was crazy! And messed up. And wrong. But it felt so fucking good! I should be feeling guilt, but I was feeling no regrets. I felt amazing. This was a long time coming and we both knew it.

Continued:

It took a few minutes for sally to compose herself and slowly sit up. She seemed blissfully satisfied, getting to her feet and giving me a lustful and Unmotherly kiss before walking away, leaving my room. I groaned and sat up, looking around. If I didn't know for sure that Elysium didn't have my mom in it, I really would have been wondering if I had died and gone to heaven.

I rolled over the bed, grabbing a T-shirt and slipping it over my head and getting up to my feet with a groan. We had planned to meet up in the dining room for lunch and later head out of the mansion for a bit of exploring and possible Capture the Flag. However, I had gotten so caught up in fucking mom that I had completely lost track of time, and now I was pretty sure I needed a nice bath to clean me off.

However, despite the intense and non stop, mind-blowing sex I had just had with sally, for some reason, my member remained rock hard, stiff and throbbing with crazy need. It seemed like it was still raring to go, though I knew that shouldn't be the case.

I sighed, then wrapped a towel around my waist, struggling to keep it around my waist as my erect shaft jutted out like a throbbing pole. I was just about to give up and toss the towel aside before going to the bathroom when there was a soft knock on my door.

I glanced up. Sally had left the door open when she had left, so I was greeted with the sight of piper standing outside my room. Her hair was scattered around her shoulders, accentuating her stunning facial features, her mesmerising eyes, her full and plump lips. She wore a simple Camp Half blood T shirt, and it was obviously a standard issue, judging by exactly how tight it was around her juicy bust. My eyes were drawn to her boobs almost instinctively, but I quickly forced myself to tear my eyes away, looking up at Piper's face. I blame my horniness for my thoughts, but there was no mistaking the look on piper's face and where exactly her eyes were staring.

Her lovely eyes were dominated by purple right now, intersped with flashes of black, perfectly matching the expression of Lustful awe on piper's face. I coughed slightly, shifting my arms nervously as I tried covering my shaft best as I could as it continued to tent my towel. But if I had hoped that my cough would pull piper's attention away from my cock, I was mistaken. Sorely mistaken.

Piper's eyes remained fixed on my member and she smiled slightly, walking into my room. "Hello Percy~" she spoke in a sultry, lilting voice that I was used to hearing from Drew, the ex Head Counsellor of Aphrodite Cabin. But I had never once imagined that my innocent best friend would one day talk to me in that same tone of voice.

"U-um… hey Piper" I licked my lips, my eyes being drawn back to her ample breasts as I watch them swing and bounce with each step. "What brings you here?"

Piper's smile turned into a smirk. "Oh~ it's just that I was thinking… a sleepover should have some… fun…" she reached up and slowly started gathering her hair in her hands. "Some… experimentation…." She snapped a band off her wrist and started gathering her hair into a ponytail. "Some… naughty activities with your best friend~" she was now in front of me, her hair pulled up into a ponytail, completely exposing the lustful look on her face and within her eyes. She slowly kneeled down, coming to eye level with my cock that throbbed and popped my towel open at last, freeing itself and exposing itself to piper's face, slapping her face. However, she didn't move away or seem annoyed. She smiled up at me, her cherry lips curving she showed off her pearly teeth." I have a great idea for a fun activity you can teach me about."

The seal of Lustful Branding on the back of Piper's hand glowed, completely fusing into her as she slowly started pulling her t-shirt off, freeing her breasts.

Ten minutes later, I was standing in the middle of my room, fucking Piper's big tits with my now fully hard cock.

"Yes, baby! Fuck them! Fuck your best friend's big tits!" Piper urged from on her knees as I gripped her big boobs, holding her tits together, allowing me to fuck the soft valley between them. I squeezed her massive jugs roughly as I fucked them savagely. It was incredible, my cock smothered in pure softness. I was on edge already and I wasn't gonna last long.

"Oh Gods, Piper. Your tits are amazing!" I groaned out.

"I know, hon," Piper said. "I know my big tits are perfect! And I know how much you love them. You stare at them all the fucking time! I've always worn extra cleavagey shirts, just so you would stare..."

"I did, Piper. I always did," I assured her, fucking those mammoth breasts.

"And I always checked out this monster," she said, glancing at my prick. "Every chance I got, I stared at your bulge. It's even bigger than I thought it'd be." Piper complimented.

"Uhhhh..." I groaned as I drove up into her, my thick prick traversing through her cleavage, the angry head appearing at the top.

"I want you to cum again, baby," Piper urged warmly. "I want you to cum on my tits! Did you hear me, Percy? I want you to cum on your BEST FRIEND'S big tits!"

"UGGHHH..." I grunted, my cock twitching in delight. "Oh Gods, Piper..." I panted. I fucked her big soft breasts harder.

"Hon, I want you to know..." she began, looking up at me as I drilled her big tits. "That no matter what I say after today, no matter how I act, or what I do... I will ALWAYS want this fucking cock! You hear me? When I'm walking around with pride in my cabin, I'll be thinking about swallowing your semen. When I'm at camp toasting marshmallows, I'll be thinking about your hands on my breasts, feeling me up. And when I'm fucking pissed at you, just know that I am this close to riding your big cock again."

"Oh... God!" I groaned, my nuts twisting.

"Do it, baby! Cum on my big tits! Cum on my big boobs! Do it! I want you to cover them with that fucking cum!" Piper urged me.

"Fuck... fuck... FUCK! UGHHH! AAHHHHHH! GOD DAMN YES!" I groaned out. My nuts flexed as I stepped back. Like a good friend, she grabbed my pulsing prick just in time to jack the first rocket of cum out, firing it directly at those big soft tits.

"Yes! Do it baby! Cum all over me!" Piper urged lovingly, jacking me off. Jets of thick, creamy semen launched from my swollen sack, sailing through the air before landing on her big tits. My white jizz coated her pure flesh, the thick white fluid rocketing out of me, painting those mammoth jugs. Shot after shot of cum jetted out of me. Piper's hand was a blur as she jacked me off, coaxing more and more of my gooey load from my aching nuts. Again and again I came, firing more thick bands of semen onto her massive, jutting tits. The thick liquid slid down the smooth skin, coating the soft flesh. Piper was controlling my weapon, aiming it so it would deface more of her massive jugs. She aimed one especially thick spray of cum across both nipples, so my thick seed was coating them. Piper's hand was amazing, enticing me into leaning forward, my heels leaving the floor as I fired off more thick jets of cum. Finally, my heels fell back to the floor as Piper coaxed the last of my seed out of me, the last few drops landing on the floor. She released her grip on me and I stepped back, panting.

"Oh Gods, Piper..." I sighed, bending over slightly. Piper looked down at herself, at her cum-coated jugs.

"I've never seen this much cum, like, ever. Holy shit!" Piper marveled. I smirked with pride as Piper snaked her fingers across her mountains, gathering warm sperm onto her fingers. She savored the flavor as she licked it off her fingers and I simply watched her excitedly. We both rested for a few moments, recovering, until finally Piper looked over at the clock.

"Oh Gods... okay, we do have to get ready now," Piper said. Even though it wasn't what I wanted to hear, I nodded. Piper stood up, and on shaky legs, gained her balance. Her cum-covered tits jiggled as she did so. "So, uh, get cleaned up. I need to jump into the shower I think," Piper said with a laugh.

"Oh, by the way..." I began, getting her attention. "Are you still vegetarian, now that you've had a taste of some juicy meat?" I teased. Piper rolled her eyes and slapped my bare chest with the back of my hand. She sauntered away, down the hall, still naked. I watched her ass as she sauntered away, shaking side-to-side. Feeling a jolt in my cock, I felt emboldened to speak out.

"Hey, Piper, you know it'd save time if we just showered together!" I said with a laugh. Piper glanced over her shoulder at me and smirked.

"You're right..." she stated with a raised eyebrow before stepping into the bathroom, leaving the door open. A jolt of excitement went through me. I cracked my neck, stretched my shoulders, and moved quickly down the hall, joining my friend's girlfriend in the bathroom, shutting the door behind us.

Not surprisingly, we got a bit carried away in the shower. It didn't take long for all signs of sex to be washed off of us, but being in such close proximity, covered with water, with my stiff cock poking into her ass, it didn't take long for things to progress. My hands ended up on her tits, spending about five minutes making sure they were totally clean. Piper was equally determined, stroking my cock, cleaning me up while making me stiff for her again. It didn't take long for Piper to end up on her knees, inhaling my cock once more, begging me to cum again, until finally, I acquiesced, firing one last load of cum down her throat.

"Okay, that's enough fooling around for now! We're going to be around the other's so we have to act normally, alright?" Piper warned me as she dried my hair while I groped and squeezed her ass.

Five minutes later, we were in the dining room, with her bent over, head bobbing in my lap, once again vigorously inhaling my swollen meat. Her nose was bumping into my torso as she sucked me off. My hand was resting on the back of her head, my fingers tangled in her silky hair as I let my head fall back against the headrest. I saw other people walking by, with no clue of what was going on right under the dining table. Piper's drool was coating my cock as she swallowed my meat, my nuts slick and smooth as she rubbed them. She was choking lightly as she sucked me, but she wasn't stopping, until finally, a few minutes later, my cock flexed as I unloaded one last huge wad of cum down her tight throat. I held her down against me as I came, only releasing her once my load was complete. She pulled herself from my cock with a loud exhale, my cock glazed with her saliva.

"Oh Gods!" Piper called out, eyes glassy with heat, her lips swollen and covered with spit. She licked her lips and wiped her mouth with the back of her hand, cleaning off the saliva. She looked at me as I laughed, causing her to grin lightly.

We waited till the coast was clear, then she quickly crawled out from under the table, straightening her dress before strutting away like nothing had ever happened, and she didn't just have a lunch full of her best friends seed. I stared as she swung her plump hips, knowing that I would be watching.

I kept one eye on Piper as I mingled a bit. I watched her play simple and sweet, hugging Jason's arm as she spoke to everyone, but I knew this was an act. I had seen the true her. The hot, amazing slut beneath the veneer. Despite how spent I was, I stiffened up at this. She looked great, and I wasn't the only one to notice how great her ass looked, or how huge and bouncy her tits were. Even the other girls were staring and Jason seemed about to drool over piper, constantly trying to make a move on her, with her calmly and easily stopping him with a smile, keeping teasing him. The other's stared at the seemingly in love couple, but I was the one who had felt up those tits. I was the one who had blasted a load of jizz all over those fucking jugs. It was my cum that had filled up that stomach. I had had that body, and it filled me with pride.

I was reminded to check my phone for the first time since leaving the room, and I smiled when I saw the picture she had sent me. A picture of Piper's big, naked breasts, posed in her bedroom mirror, no doubt taken after she had jumped out of the shower. My cock pulsed again and I smiled dreamily, wondering what would happen during capture the Flag.

A.N.: Iamjmph01, you had a question about why I've included other guys in the story, since Aphrodite wants to make Percy into the strong Harem Master. Thank you for the great question, it's why i'm updating, so I can clarify this quickly.

No, Percy is not Bi in the Fan Fic, nor will he be sharing his girls out with the other guys. Rather, I wanted some variety while writing these situations, so I decided to have the boyfriends around while the girls get stolen away by Percy. Like I said previously, I want to create a dark Percy, so it seems more appropriate to do that. Also, the reason Aphrodite has called them, is because she loves drama, and more importantly, I mentioned in the start of the story, the sleepover is annabeth's idea and she has called all the friends over. For the sake of a little bit of realism, it seems better to call over both guys and girls for a normal sleepover.

Also, it's boring to write about Percy creating his harem without any resistance from the other guys. I'm planning to maybe have a competitor against Percy? Let's see what happens.

Do review ideas and suggestions for who gets fucked and how during the Capture the flag. Also any suggestions on how the teams should be split?

Current people at the sleepover: Guys: Percy and Jason
Girls: Katie, Hazel, Piper, Sally, Aphrodite, Hestia, Sadie, Bast, Alex, Samirrah, Zia
