Percy x Jason x Annabeth:

Annabeth and Percy were in the Poseidon cabin, both laying on Percy's bed staring at the ceiling, occupied with their thoughts. The blonde-haired girl thought about their little agreement which allowed them to sleep with different partners, if the other one gave his or her consent, but what about the two of them having sex with a third person? A threesome...

Annabeth was not sure if Percy would like it or not, but she was about to find out - she had learned a while ago, that it was best to just confront Percy directly about her sexual wishes instead of just giving hints. Thinking about what she wanted, she turned her head towards Percy and said: "What do you think of having a threesome?". This got Percy's attention and he turned his head, looking at her with a spark of anticipation in his eyes. "Who would you have thought of?" he asked her. She looked him in the eyes and replied "Jason, I want you and him to fuck me together since I slept with him."
Percy rolled himself to his side and then on top of Annabeth, supporting himself with his arms so he wouldn't crush her. Trapped between his arms, which were positioned just next to her shoulders Annabeth starred up towards him. He slowly leaned down and kissed her on the lips, making her want more, but he leaned back a bit and murmured against her lips: "I'm sure this can be arranged."

Annabeth smiled and leaned up to kiss him again. As they broke apart, he asked "When do you want to do it?". She replied "Well, I'm kind of needy right now, but we don't know if Jason…" - she couldn't finish her sentence as Percy cut her off saying "I'm sure he is more than willing, I will check if he has time right now."
Annabeth felt the same anticipation she had seen in her boyfriend's eyes just seconds before flowing over her now. Percy stood up and was already on his way out the door to search for Jason, but turned a last time, looking at his girlfriend and saying "I'm right back and when I'm here again, I want you naked and ready for us!"

With these words Percy left the cabin and Annabeth starred at the empty space where he just stood.
She shook herself out of the stupor she was in and stood up from the bed to relieve herself of her clothes. Her panties where the last piece of fabric she striped out of and as she looked down to the pile of clothes on the floor, she could see that there was a dark spot on the grey fabric, from where it has touched her wet cunt.

Annabeth laid down on the bed again and slowly started to prepare herself for the coming event. She started with fingering her cunt with her right hand while messaging her clit with her other one. As her vagina was already wet from the beginning and was soon soaking, she moved on to prepare her tight asshole. Still circling her clit with her left hand, she started to slide her right index finger in and out of her butthole slowly, using her own juice, which still covered the fingers of her right hand, as lube.

The first times she had something or someone penetrate her ass it was a weird and slight painful sensation but every time she relaxed faster and soon it brought her pleasure to move her finger in and out. Annabeth added another finger and started to spread her asshole slowly. Working on her ass, she remembered something she had bought for such occasions. The blonde-haired girl let go of her clit and reached for the second drawer of Percy's nightstand. Opening it she pulled out lube and a big butt plug. She applied a bit of lube at her still tight hole, put some of the lube on the plug and started to stretch herself with the toy, which got wider and wider the farther she slid it in. As she had the toy as far inside of her as possible, it anchored itself inside of her because of its shape and elicited her a moan.
Prepared as good as possible for what was coming, she hoped that Percy would come back soon and hopefully accompanied by Jason.

Unnoticed by the girl in the Poseidon cabin, Percy and Jason were already near their destination. Percy had found Jason masturbating in his cabin, the son of Zeus was needy, horny and agreed eagerly. He had quickly slid on loose pants and followed the son of Poseidon back to his cabin. Both of their pants formed a tent at the front because of their hard cocks pressing upwards in anticipation. Jason still had his boner form when he started to masturbate and Percy was thinking about Annabeth and how he would soon fuck her with Jason, arousing him more and more as time passed.

Soon, they reached the Poseidon cabin. Percy quickly opened the door and both entered the cabin and was greeted by a more than exhilarating view. Annabeth was laying on her back in the middle of the bed, eyes closed, legs spread apart, one hand grabbing for the sheets while the other one devoted attention to her pussy - a big butt plug inside of her asshole. She did not stop her movements and the two aroused boys concluded that she had not heard them come in.

Quietly, but quickly, the two got rid of their clothes and made their way toward the bed.
Percy grabbed both of Annabeth's hands and brought them above her head, holding them in position he leaned down and started to kiss her. Taking the opportunity Jason placed his hands, where the girl had hers just a second ago and started to stroke her clit while letting two fingers glide in and out of her soaking pussy. Momentarily surprised at the second pair of hands on her body Annabeth let out a small gasp, which aloud Percy to slide his tongue into her now opened mouth. Their kiss got more intense and she could feel how Percy's hands travelled down to her breasts. He cupped them with his strong hands and started to stroke his thumbs over her hardening nipples, while Jason still slid his fingers in and out of her.
Suddenly there was a new sensation added to the kiss, the stroking of her nipple and the pumping fingers - Jason suddenly started to circle her clit with his tongue, making Annabeth moan in pleasure.

The boys looked at each other and nodded, both stopping their efforts to pleasure the girl between them, which earned them a disapproving look from the blonde girl.

"Get up on all fours and come here!" Percy said towards Annabeth, as he positioned himself standing at the edge of the bed. The blonde-haired girl eagerly complied with his demand and crawled towards him, her face directly in front of his hard cock. Hearing movement behind her, Annabeth looked over her shoulder just in time to see as Jason lining up his dick with her pussy. She heard as Percy cleared his throat and turned back around. The demigoddess knew he was impatient and wanted her to start sucking his dick, so she grabbed it and lead its tip to her opened mouth, but just before she could take his dick in her mouth on her own, Jason slid into her with a strong thrust, moving her whole body forward and forcing her to deep throat Percy. Jason started to shove himself into her at a constant pace, pulling her back a bit every time he slid back and forcing her forwards onto Percy's dick every time he thrusted into her wet pussy with a grunt. Percy moaned every time Annabeth took his cock in and soon, he felt how his balls started to tighten - he wouldn't last much longer.
Suddenly Annabeth moaned out loudly as she came, starting a chain reaction. With her orgasm she caused Jason to reach his climax too. He rammed his cock into her cunt with a last powerful thrust to come deep inside of her, while pushing her towards Percy who was more than happy to shoot his own load of creamy cum down her throat.

After finishing off, the boys pulled out of her but all three knew they weren't done yet.
Immediately, Jason and Percy started to stroke their dicks to make them hard again, wanting to be ready to fuck Annabeth again as soon as possible. The girl welcomed the short pause to catch her breath but thanks to their godly half, Jason and Percy soon were ready for the next round.

The son of Jupiter took a seat on the edge of the bed, looked at Annabeth and said "Bring your pretty ass over here." while pointing at the floor in front of him. Percy watched as his horny girlfriend crawled in the direction of the blond-haired demigod - when she reached the edge of the bed, she got up and stood in front of Jason. "Turn around and bend over a bit!" he said. As the girl did exactly what he told her to, she showed of her drenched pussy and the butt plug that was still spreading her asshole, preparing it for their dicks.

The black-haired son of Poseidon, who was standing next to Jason grabbed the plug and started to pull slowly. As the plug came out, it left her ass slimy with lube and ready to be fucked. Jason pulled her ass towards its destination with one hand, while holding his cock in place with the other one. Annabeth moaned as he pulled her back into his lap, taking his whole rod into her, stretching her wide just as the plug had a second before. Concentrating on what was in her ass she was barely aware of Percy, who was now standing in front of her and Jason, grabbing her legs and spreading them apart, giving him best access to her vagina. Only as he slid himself into the cave between her legs, she started to register what was going on. The two boys haven't stared to move yet, but Annabeth was already in heaven, she had dreamed of this feeling but she haven't thought it possible until her deal with Percy. She felt so full and was eagerly awaiting the two cocks inside her to start moving.

Percy and Jason began to work in unison - they lifted Annabeth a bit to have more room to move and then started, slowly shoving their cocks up and down. Every time they were up and had their cocks almost completely buried inside the girl, she let out a quiet moan. The young demigoddess tried to stop them from escaping her mouth, but she could not help it and made the noise every time she felt them fill her completely. Jason covered the back of her neck with kisses, while Annabeth had her eyes closed and bit down on her lips, which was a more than welcomed sight for Percy who started to push into her faster - Jason instantly followed the new pace.

Percy leaned forward and started to kiss his girlfriend, the taste of his own cum was still in her mouth. As the boys fastened their thrusts, Percy had to stop kissing her because soon all three of them breathed heavily. With each thrust the two men did, Percy could also feel Jason's dick move inside of Annabeth, it was not only pleasuring Annabeth, but also rubbed against him, making him think of the time he and Paul had fucked Sally together.

Percy felt himself nearing his climax and looked towards Jason, only to see him in the same position. Both tightened their grip on Annabeth and forced themselves even harder into the girl - she screamed out and reached her climax, spreading her juice all above Percy's dick who couldn't hold back any longer either and came deep inside Annabeth's pussy. As Jason felt how both his partners came, he let go of his restraint, reached his climax and spread his halfgod-cum inside of Annabeth.

All of them were covered in a layer of sweat, but none of them cared, it felt too good. All to quickly for Annabeth's liking she was lifted and Jason started to pull his cock out of her ass, leaving her with a feeling of emptiness. But this feeling didn't hold long because as soon as Jason had himself removed completely from Annabeth, he pushed her butt plug into her, keeping his warm seed from leaking out. "Thanks for the fun, we need to repeat this soon." Jason started and continued with "For now I have plans with Piper. I'll leave you two be."

As Jason grabbed his shorts and made his way towards the door, Percy started to climb on the bed, Annabeth still sitting on his cock with her legs hooked around his waist. Both would take a nap, they could always clean up the mess they made afterwards.
