Annabeth POV

I couldn't believe it, when Thalia asked to meet up after hours I didn't know what would happen. I was a little late because I had to talk my way round one of the younger campers but then when I did arrive I… I saw Percy, with her, my best friend. Thalia naked laying on the floor moaning while Percy, he… I can't even think for the right words. I felt an immediate stab of pain and betrayal, even worse than when Luke had left us and tried to destroy Olympus was nothing compared to this. I sat there kneeling on the floor while Percy just kept doing her. I had watched Thalia scream her orgasm twice then take Percy in her mouth before jumping onto him before I finally left silently. Now I lay on my bed unsure of what to do, I love Percy but by the gods I should hate him in a way this wasn't the worst part or the weirdest. I should have just shouted the moment I went into the tent doorway but no I hid, I just watched. He even then I should have done something but…but…but, well part of me… I think… enjoyed it. As I'd watched my boyfriend just…I don't know why but I couldn't help but be a little aroused. My hands had stared to move on me. I just had this urge to…to just touch myself. When my hands had moved closer to between my legs the shock and weird feelings had become too much and I'd gotten out of there. I just tried to sleep it off in my cabin, I sat there alone in my cabin the next morning thinking about what I'd seen and I just got that weirdly aroused state again. I avoided Percy that day and Thalia, I couldn't stand to look at them I was so confused about how to feel I had no idea how to or what to say to them. The next day I woke up and waited till the cabin was empty I just lay on my bed thinking. I mean some couples didn't always stay with each other right? Some people swung or is it swing? But Percy hadn't asked or Thalia… would I have agreed. After thinking it though over and over again. Percy had defiantly cheated on me that was clear but I didn't want to dump him, I still loved him. As I got though the camps day I couldn't help run into Thalia I tried to act normally to her but I was relieved when she left. I finally found peace on one of the camps slopes but a familiar voice disrupted my thoughts.

"Annabeth?" said Chiron

I almost fell over when he spoke it had come as such a surprise.

"O sorry, what did you say?"

Chiron smiled to himself

"Lost in thought? I must say most unwise for a demigod"

I understood his logic, not seeing a wheel chair approaching could well have been a monster and she definitely wasn't going to go down in history as the demigod who was killed while day dreaming.

"I'll be more wary next time, did you want something Chiron?"

Chiron adjusted himself in his wheel chair looking weirdly uncomfortable.

"I didn't mean to ask but… have you noticed anything… about a certain son of Poseidon would you?"

I felt my face blush and I turned away

"Err…what aspect would you be enquiring about?"

Chiron sighted

"It's probably nothing it's just… something's different I think… I don't know maybe it's just a nervous trick upon my mind"

Before they could speak anymore the horn blew for the nights feast so Chiron and me split ways. Chiron was right something about Percy was different but whatever it was I just wanted him more for it, she'd been so happy only two days ago. Percy was prefect as he was, perhaps Chiron was sensing that Percy and me had finally been 'together ' which had changed his behaviour. The more I thought on it that had to be it. The confusion finally stopped the next morning I was laying in my bed thinking about Percy and Thalia. I imagined them together and I couldn't help thinking about how…hot Thalia had looked, how much I still wanted Percy. My right hand gently moved up my body just to feel my breasts, my nipples were hard from thinking about Percy. I thought about tasting Percy or maybe Thalia. My left hand slid down my body as I thought about us, me and Percy.

Percy POV

I felt guilty I mean Thalia was hot and she was amazing when we had sex but I loved Annabeth. I had cheated on the girl id fought for and now things were quiet. I hadn't seen Annabeth since that night. She was around the camp but never where I was. It had been three days since me and Thalia had been together and Thalia had spoken to her once on the second day I woke up each morning worried about her and what had happened. It's now the third day and still no Annabeth I ask around camp, her cabin and finally Thalia but still nothing. I was walking away from the big house when Thalia ran up to me.

"Percy I think she knows"

I gulp down the guilt

"What?"

Thalia spoke in a nervously fast pace which reflected the panic on her face, she felt as guilty as I did. After all she and Annabeth had known each other longer than Annabeth and me had gone out.

"She found me and said she wanted to talk to both of us in your cabin when the camp is quiet, when nobody is around. She didn't say what about but just her tone of voice and how she looked at me Percy… she must know!"

I felt my breathing pick up as my heart went into an irregular pace. Thalia was wearing her Hunter's gear as always. The camouflage top with the knee long skirt, It was somewhat of a relief that she had chosen herself a longer skirt than before when we'd been in the tent because it was making me less horny. I shook my head, thinking about Thalia wasn't going to help with Annabeth. We both walked down together to my cabin at midday. All the rest of the camp was competing in various games against the Hunters. The only people we saw was one girl from the Aphrodite cabin who was late she blushed when I looked at her, when she smiled back her eyes had that glint that Thalia had or those other girls had. I thought to myself that could cause trouble but I didn't have time to think about it as we walked up to my cabin door. Thalia and me held hands for a moment before opening the door, Annabeth was already inside sitting on my bed. If you're curious the bunk beds we use to have we donated to the other cabins, I mean my cabin only holds Tyson and me if he even visits camp. It seemed stupid to have all those beds so we exchanged them for two normal ones. Annabeth was just looking at us with her grey eyes

"Close the door please" she said in a strict voice

I did so and locked it with the new lock id gotten from the kids from the Hephaestus cabin, I thought it was a wise idea if me and Annabeth planned to do anything against the rules but I'm sure that's all about to end now. The silence was horrible for that first minute nobody said anything or made any noise. Then Annabeth stood up off the bed. She was wearing her normal jeans but she had decided not to wear the regular camp half blood shirt instead going for a yellow tank top.

"Annabeth I…" before I could speak she interrupted me

"I saw you Percy," her head moved to Thalia

"And I saw you"

Thalia to my right started to try to explain

"Annabeth I'm so so sorry, I didn't mean to hurt you… I mean I didn't want… I didn't,"

Annabeth raised her hand to shut her up. She looked at me then back to Thalia, she walked a little closer to us and paused next to an almost shaking Thalia to stare at me.

"You know what I hate Percy Jackson"

I couldn't speak from how much I dreaded her rage

"I hate the fact both of you didn't tell me… how was I meant to join in?"

I almost choked then

"What?" before she could answer me she went up to Thalia and grabbed her face kissing her. Thalia was as shocked as me I heard her make a light grunt from the unexpected reaction. Annabeth kept kissing her with passion and as I watched Thalia relaxed into her moaning as she let Annabeth's tongue come into her mouth. Their bodies both swayed a little trying to finding some sense of balance. Thalia's hands moved up to Annabeth's hips. Annabeth finally pulled off her taking deep breaths while doing so. Annabeth grinned as Thalia laughed in relief.

"I think I may have wanted to do that for a while" Thalia said in-between breaths. All the while I stood dumb struck sure of what to do. Annabeth turned to me smiling then she started kissing up Thalia's neck. Thalia moaned lightly and let her head roll back. Brushing her lips up to her ear and whispered something to Thalia. Thalia giggled before kissing Annabeth again this time they started to move towards my bed until Annabeth's legs hit my bed end. Annabeth's hands went to Thalia's top pulling it up over her head and throwing it by my feet. Thalia moaned louder as Annabeth kissed the top of her breast that her black bra didn't hide. Thalia did the same taking off Annabeth's top to reveal her bright blue bra. I was getting incredible horny by this point as these hot girls made out next to my bed. Thalia was undoing Annabeth's jeans as she kept one hand on her gold curls kissing her. Annabeth's jeans were pulled down but Thalia couldn't go much further than just above her knees. A tent had formed in my pants as I watched Annabeth with her tanned body up against Thalia's paler body. Annabeth had bright pink panties on in stark contrast to her bra. Annabeth swayed her hips and used her own hands to remove her jeans and throw them across the floor. Annabeth went back to kissing Thalia's neck while her hands went under the hem of Thalia' skirt and more. Thalia moaned more as Annabeth moved her hands in Thalia's panties. Thalia took a few minutes to control her lust and reacted around Annabeth's back undoing her bra. As she flung the bra at me she gazed at Annabeth's chest. Her lips went to Annabeth's right breast while she kneaded the other with her hand. Annabeth groaned and in response went faster in Thalia's panties. I was still in shock unsure where or what to do but watch, I groaned as Annabeth stopped Thalia then went to her knees in front of Thalia, her hands went up under her skirt and pulled down her black panties throwing them at me. As Annabeth slowly slid back up she took off Thalia's bra sending it across the other end of the cabin. Now Annabeth only had her socks and panties on and Thalia only had her skirt, sockets and shoes left. Annabeth looked over to me.

"O… poor Percy he hasn't had any attention. Thalia shall we help him"

Thalia quickly took of her hunter shoes while Annabeth came up to me and kissed me. I broke it away quickly

"Annabeth I want you to know that I'm still sorry over…" she stopped me by placing a finger over my mouth and hushing me.

"Percy its fine, I thought it was hot and please… just have fun" she spoke in her o so sexy voice her eyes like Thalia had lust him them as they kissed me. At first they both tried to get my lips but it seemed to chaotic so Annabeth being the smart one let Thalia kiss me while she took of my shirt. Thalia defiantly was more wild when it came to kissing, it was hard to concentrate on what else was happening around me. With my shirt gone Annabeth went to my belt but I'm not sure like I say Thalia had me very distracted. I felt my jeans get pulled down and then Annabeth's hands slid up my thighs to my boxers. She messaged my dick though the cloth making me groan into Thalia's mouth at the sudden stimulation. Thalia stood back curious at my groan to see Annabeth dragging down my boxers. My erect cock made both of them lick their lips. Next thing I know Thalia's on her knees next to Annabeth staring at my cock. I moan as they both start licking the head and moving up and down the underside. Annabeth uses one hand to handle my dick while her other slips under Thalia's skirt. Thalia moaned as Annabeth's fingers found her clit. Annabeth smiled

"Thalia have you tried taking Percy in your mouth"

Thalia replied by nodding and moaning as Annabeth sped up her fingers under Thalia's skirt and jerking me off in the other hand. Annabeth giggled to herself.

"Why don't you take Percy first?" she asked her voice just so sexy to Thalia and me. Thalia in response put my dick's head into her mouth gently sucking while Annabeth jerk me off still. Thalia's tongue swirled around my head before flicking across my tip. Annabeth decided to switch things round so she removed her hand from the base of my cock and use it to gently push Thalia's head. Thalia quickly took the encouragement and started putting more of me into her warm mouth. Soon my hands are in her black hair pushing her up and down on my cock as her pace quickens. Annabeth moved behind Thalia both her hands rubbing and fingering Thalia, she kisses her neck and bucks her hips as Thalia does. By the gods Thalia's good at blowjobs. To my alarm she stops moaning and slows herself. She looks behind to Annabeth.

"Annabeth you have to try Percy…" she pauses to breathe "he tastes sooo good"

Annabeth kisses Thalia deeply before moving to me.

"So Percy does she give good blowjobs?" Annabeth asked innocently.

I mentally panic wondering what I could say… or should I be honest.

"Oh she gives them better than you" I went for the honest approach dreading id been an idiot. Annabeth shrugged.

"Well" she said jerking me off in her hands " I think I'll just have to change your mind" with that Annabeth went straight to deep throating me, gaining pace very quickly. I don't know how but she had gotten better since last time she had tried to suck me off, maybe it was a hidden urge to be better than Thalia but whatever it was her tongue was amazing. Thalia just sits there touching herself watching as Annabeth quickly finishes me off. I moan as I cum into her wet mouth. Annabeth moans enjoying the taste of me more than you'd think, she slows down but keeps sucking me making sure she has all my cum but she doesn't swallow it. Annabeth carefully takes me out her mouth painfully slowly the turns to Thalia grabbing the other girl by the back of her head she pulls her in for a kiss. While Annabeth holds Thalia's head in place with one of her hands, Thalia bridges the gap between them and places her hands on Annabeth's hips. The girls are so close now, Thalia closes her eyes as she opens her mouth for Annabeth's tongue. Annabeth then feeds Thalia my cum as they kiss, both girls moaning at the taste. I stand there seeing something id never imagine id see in real life. This has to prove that Annabeth is a genius. The girls finally break the long kiss after I groan from watching them together. Annabeth happily wipes her mouth on her hand.

"So… did I change your mind?"

I can't quite speak so I just nod making her laugh. Annabeth looks back to Thalia and they both jump up off the floor and get onto my bed. Annabeth pins Thalia underneath her before kissing her again.

"You know I've wondered what it would be like to kiss you" Thalia says as they break their kiss. Before Annabeth can react Thalia flips them over and starts trailing kisses down Annabeth's neck downwards. Annabeth's looks over to me, I'm still standing where I was… hell I didn't know what I should be doing I was just enjoying the show.

"Percy… don't you want to join in" Annabeth suggests in-between moans from Thalia who now has got down to her breasts. I quickly join them not wasting the invitation and decided to kiss Annabeth. I can taste Thalia on her tongue but I stop as Annabeth moans loudly into my mouth. I turn round to see that Thalia has gotten down to Annabeth's belly button. I remember then how much Annabeth liked to talk dirty, I mean she shouted out during sex unlike Thalia that just sexily moaned. I leaned down to Annabeth's ear while my right hand found her beasts to play with.

"Do you want Thalia to lick you?" I whisper to her, she groans in response as Thalia gets lower down.

" Do you want Thalia to lick your pussy Annabeth?" this time Annabeth replies

"Gods yes Percy"

I smile and look to Thalia who had listened while she got closer to Annabeth's panties.

"But if she's licking you what should I be doing?" Annabeth looks at Thalia and whispers back.

"I want to see you two again"

With that I moved away and down to the end of the bed with Thalia. Thalia was now kissing Annabeth just above her panties and it was driving Annabeth mad. Annabeth was rubbing her legs together to get some needed friction, from everything we had been doing Annabeth's panties were really wet. Thalia looked up to me to check I was watching as she finally kissed Annabeth's panties, her tongue sliding along the damp fabric. My still hard cock needed some attention so I slowly masturbated as Thalia made my girlfriend moan. Thalia stops just as Annabeth's moans start to get too loud. Both her small hands come up and pull Annabeth's now very wet panties off and with a flick of Annabeth's legs the piece of clothing fly's off somewhere into my cabin. Thalia goes back down onto Annabeth, first sucking and lightly licking her clit. Then moving onto licking her pussy, pushing her tongue in deeper. Thalia arch's her back making her skirt covered ass up, the skirt was longer than the others she'd been wearing in the past few days but even so in that position I could see more of her legs and I realised what to do. Thalia didn't see me come up behind her and let my hands down under her skirt. Feeling down her smooth skin to in-between her legs her tight pussy was as wet as Annabeth's. Pulling my hands back they slipped up to Thalia's hips, she now knew what was happening and wiggles her hips as encouragement to go on. I plunge my dick into her pussy remembering how tight she was, Thalia's head lifts off Annabeth's pussy as she loudly moans unable to lick Annabeth and have me at the same time. Annabeth places both her hands into Thalia's hair forcing her back down onto her. I speed up pumping into Thalia's tight wet pussy making her moan more which just gave Annabeth more pleasure. I'd never seen Annabeth more happy as her hips bucked and she repeatedly called out my and Thalia's names, like I said Annabeth seems to like being vocal in sex. Annabeth finally screams hitting her orgasm relaxing back into the bed with a happy sigh, closing her eyes to enjoy the feeling. Thalia free of licking Annabeth's pussy moans out loud, her pussy gets tighter as she reaches her own climax. I grip hard into her hips still pumping making her groan louder and her high greater before her tight, tight pussy is too much for me and I groan as I cum deep inside her. Her arms give out and she falls next to Annabeth with a blissful look on her face. I join them panting from all the exercise.

Thalia lightly kisses Annabeth

"Thank you for being so…understanding Annabeth"

Annabeth laughed

"Thank you for looking after my Percy" her hands drifted over my chest as she spoke, I leaned down kissing her, my love, my Annabeth. I looked over to Thalia

"I'm sorry Thalia I know we didn't have protection and I…" I stopped as both the girls laughed

"What?" I asked

" You are silly sometimes Percy" Annabeth told me

"Hunters of Artemis can't get pregnant, just like we don't grow up" Thalia answered
