It didn't take long for the creatures poison to take effect in Pipers system, leaving her horny and vulnerable as Annabeth wrestled her to the floor next to the unconscious oracle. Somewhere in her mind Piper knew this wasn't her, but her body was compelled to submit to the blondes advances as she tore her clothes from her body. "I always found you attractive pipes" Annabeth said as she yanked the girls trousers down, dragging her nails over the soft fleshed her legs. "I'm glad we finally get to do this."

"Why are you doing this" she asked, her voice wavering as she spoke like she was drunk. "This isn't you.." she tried to say, but Annabeth climbed on top of her and kissed her passionately, pushing her tongue deep into her throat. Piper received another dose of saliva and cum, intensifying the haze in her mind until she was frantically groping the girl in response, making out on the floor of the cave.

Once Annabeth was satisfied she was completely intoxicated with her she broke off the kiss, staring down at her half naked body as she stood over her, brandishing her sex to the brunette. "You know you want to" she purred, guiding Pipers face to her pussy.

Piper tried to resisted her impulses but she couldn't stop herself from latching onto her clit, thrusting her tongue into the demigod tasting her addictive juices. Gods, Percy is so lucky she thought as she ate her out like a puppy, munching on her sex listening to Annabeth's happy got so turned on her own panties became soaked in response, reaching down to rub the dampness desperately.

"Yes, fuck, yes. You really are the love goddesses daughter" Annabeth cried as Piper brought her to orgasm, her hips buckling against her covering her in cum. Her legs wobbled until she fell into the girls lap, embracing her tightly kissing her, delighted when she kissed her back. They locked gazes, both their eyes foggy with lust, a smile growing on their lips. The next thing Piper knew she was bent over Rachel's unconcious body with Annabeth fingering her ass from behind. "I've always wondered what this would taste like" she cooed, pulling her finger out of her stretched arsehole so she could insert her slick tongue inside.

Piper screamed as she was fucked in the ass, her hands clawing at Rachel's flesh. She could feel the girl shifting beneath her, hear her shallow breathing. A part of Piper hoped she was okay, but the rest just felt the urge to molest her naked body while she was being fucked from behind. She grabbed one of the oracles nipples with her teeth to muffle her screams as Annabeth plunged three fingers into her pussy, stretching it wide as she licked her arsehole. She felt like her head was about to explode, her thoughts turning numb with pleasure. She wondered if she'd willingly fuck Rachel's unconscious body of Annabeth asked her too. Gods, what is she doing to me!

Finally she came into Annabeth's hand, her body shuddering through the climax until she collapsed in exhaustion on top of Rachel. Annabeth removed herself from the girl to let her catch her breath, licking her fingers clean. "Perfect" she whispered, rolling the demigod onto the floor on her back so she could kiss along her breasts and neck.

Piper gasped for air staring up at the ceiling, the fog lifting slightly long enough for her to gather her thoughts. Something was wrong with Annabeth, she knew that much. Whatever it was also affected her, and maybe the others. Is this why she couldn't remember anything from yesterday. Did she have sex with Annabeth? No, something came back during sex while she was licking her pussy, a sensation of being filled like she was fucking someone. Or something was fucking her. "Annabeth" she asked, lacing her words with charm-speak to compel her best friend to answer, "what happened to you?"

For a moment she froze, her eye twitching like she was struggling with a problem. Or whatever had corrupted her was resisting the charmspeak. "The weaver" she replied reluctantly. "He found me, made me his assistant. Serve him now."

"Who's the weaver" she pressed.

Annabeth struggled to speak, her lips trying to force themselves closed. "I don't know" she said.

"What does it want with us?"

Annabeth's gaze locked onto Piper, a cold scared look in her eyes. "He wants to evolve" she told her. But before Piper could ask more questions, Annabeth's hand came up covered in cum scooped out of Rachel's cunt, forcing her fingers down Pipers throat silencing her. "He's curious about what he can do" she continued as she force fed Piper her masters poison. "We're his playthings to experiment with. Don't worry, he doesn't want to harm any of us. And you won't remember anything when the morning comes." She leaned down and watched as her kaleidoscope eyes became dull and foggy, gazing back her her with lust and delirium. "Now hush my lover. And let us experiment until he returns."

And so they did, for hours. They fucked long into the night. Annabeth had intended to have sex with Piper until she was too exhausted to remain awake so she could move on, but the daughter of Aphrodite had an unhealthy libido. As long as they were ready to fuck she remained awake. At one point Annabeth thought she might pass out, but her masters will was strong, keeping her conscious to continue as they cycled positions, techniques, using their tongues or fingers or feet or other toys at they disposal. As the weavers proxy the creature got to watch the whole thing through Annabeth's eyes. He found it curious and amusing, a strong test of the daughter of Athena's willpower and conviction. And Piper was a formidable lover. He looked forward to returning to her.

Piper fell onto her back gasping for breath, her arms aching covered in bruises, her body exhausted. Above her Annabeth was panting dripping with sweat, her hair matted to her skin drenched with fluids. Pipers hair wasn't much better as it cling to her neck and shoulders, obscuring her vision until she weakly pulled it aside. "Fuck" she panted, her throat hoarse as she tried to talk. This was the longest she'd ever had sex with anybody in her entire life. She couldn't fathom how she was still conscious. She was even more surprised to see Annabeth managing to keep up with her. But one look at her exhausted face as she could see it was taking a toll. Her eyelids fluttered shut as her head lolled forward, on the verge of passing out, but then they reopened like she'd been prodded or tased. Something was keeping her awake and moving, forcing her to fall down onto pipers chest and suck on her boobs. Piper deduced she was able to last so long due to being the daughter of the love goddess. "Annie, we need to stop this" she whispered, trying to stifle the moans as the blonde assaulted her breasts. "Think of Percy. You don't want to cheat on him!"

"It's too late for that" Annabeth replied, grabbing her by the hair to yank her into another kiss. Piper was forced to return the affection and soon they were grinding their pussies together until the climaxed for the seventieth time.

They collapsed with their legs intertwined, gasping for breath as their bodies pleaded to give in to exhaustion only to be denied by otherworldly forces. "Why?" Piper asked, willing her charmspeak to work pushing her aching body to a sit up. "Why did it want you?"

"Because I wanted it" Annabeth told her. "Rachel was the first, but she was mortal. She resisted his will. But I was it's first lover. And after that night nothing could compare. Percy couldn't compare. I had to find it again. I have myself to his service."

"You chose this?"

"Yes. I joined as his assistant, not a puppet. My mind is my own. My pleasure, my lust, my choice" she explained, forcing herself onto Pipers lap to munch on her cunt once more.

Piper moaned as her clit was assaulted, clutching at the floor writhing in reluctant burning pleasure. After hours of sex her pussy was overstimulated and intensely sensitive. The slightest lick could set her off and Annabeth's tongue was virtual agony and bliss rolled into one. "This monster raped Clarisse and Rachel" Piper argued. "It raped you! It raped me too, didn't it?"

"It fucked all of us" Annabeth clarified. "And more. I let it fuck Percy as a gift too. It's spreading its seed to the rest of the camp. And when it comes back, we can enjoy its seed together."

"No" she pleaded. "We have to leave. We need to warn everyone!"

"Why? They won't remember anything. Neither will you. That's why this moment is special. And I don't want to leave. I need him and his cock, his seed. You need to stay" she said, trusting her fingers into Pipers pussy making the girl scream into painful orgasm, watching her collapse to the floor before climbing on top of her to kiss her roughly, coercing her into further lesbian sex to keep her restrained. Piper had no choice but to submit and have sex with her best friend.

Half an hour later they were on their knees staring at each other, scratches on their skin, bruising around their sexes, sweat dripping from their faces panting heavily, muscles aching, lungs and groin burning, minds fuzzy from exhaustion. Piper prayed to her mother to just let her pass out, she didn't want to do this anymore. "Please Annie. I don't want this" she begged.

Annabeth seemed to agree, her expression tired as her head lolled on her sagging shoulders. But then her eyes looked up over Pipers shoulder, her back straightening for just a moment, before she saw her lips curl into a tiny smile as she sighed, her eyes falling closed as she fell to the side collapsing to the floor. Piper instinctively rushed over to her, finding the girl finally asleep snoring peacefully. Her master had finally given her permission to rest, because (as Piper realized as she turned around) it had finally returned to the cave.
