Percy x Artemis:

All her hunters still thought she didn't know what they do when their mistress is not present - when she, for example, rides her moon chariot - but Artemis knew everything that happens under her moon. The goddess always kept an eye on her hunters and so she found out about their activities long ago, not that she cared that much, she did it herself after all.

Once she secretly watched Thalia in her cabin, when the hunt stayed at camp. What she didn't expected though, was what happened when Percy once surprised Thalia while she was masturbating.
Artemis was furious - how could the boy have sex with another woman when he had his girlfriend? She understood quite well that human bodies got some needs you need to attend to and she was thankful for Percy bringing one of her hunters relief, but she couldn't help but feel angry at him.

That is, until she found out about Percy's deal with Annabeth.

She kept an eye on the son of Poseidon from then on - he stilled not only his own needs, but also his partner's. Artemis couldn't help but feel her own desire and need build inside of her and she wished the black-haired demigod would take care of her too, just like he did with the others. Deciding she had enough of the tension inside her and the hot feeling between her legs she teleported herself right in front of the door of cabin 3 in Camp Half-Blood.
Before she could think a second time about what would happen, which would probably cause her to pull back, she knocked on the wooden door.

It only took a moment and Percy opened the door. "Lady Artemis!" he said, surprised as the goddess of the hunt stood in front of him in her older, eighteen-year-old form. "How do I own this honor?" he added a bit cocky while he stepped back and allowed her to enter his private cabin.

The goddess waited till he closed the door, then turned around to face him and spoke outright "I know of your leisure activities, Perseus.". The young demigod turned a bit pale and wanted to start talking his way out, but Artemis lifted her hand and gestured him to stop. She took a step towards him, leaned a bit forward and whispered "I want to be part of it too!".

Percy was stunned and stuttered "Wha… - What did you say?" but instead of answering him, the pretty woman in front of him pushed herself against him and captured his lips with her own. Her hot, soft lips felt wonderful on his and he automatically kissed her back. A small moan escaped him as the auburn-haired goddess pushed him back against the closed door. The kiss heated and Percy could feel how his cock started to get hard. Artemis had her body pressed against his and seemed to notice it too - she pulled back and whispered four small words that should change everything: "Please fuck me, Perseus!".

Artemis snapped her fingers and their clothes disappeared into nothing, leaving them naked. Percy admired the view and watched with growing anticipation as Artemis kneeled down in front of him. On her knees, her face lined up with his semi-hard dick and Percy swallowed audible. 'What would it be like with a goddess?' he thought while he already knew he was going to find out soon.

The kneeling woman grabbed his shaft and guided it towards her opened mouth - the black-haired demigod watched with amazement as the goddess started to suck his thick cock. Percy groaned and closed his eyes to enjoy the feeling of her wet tongue and her hot mouth while she bobbed her head back and forth at a steady speed. He didn't know how much time passed, but all to soon Artemis stopped her efforts and stood up. He wanted to complain and ask why she stopped but when he looked down and noticed that his dick was now fully erected, he knew - the little blow job she had given him was just the warming up.

Artemis stepped closer and pressed her body against Percy's - pressing her boobs against his strong, muscular chest and her lower half against his erection in the process. She grabbed his shoulders while he placed his hands on her hips. Artemis lifted her right leg and wrapped it around Percy's hip as good as possible, with the wooden door behind him. He felt the sensation of her wet arousal against his hard cock and couldn't stay passive any longer. His hands slid down and he grabbed Artemis's ass and picked her up, causing the goddess to wrap her other leg around him as well. Her wet pussy pressed against him and he couldn't wait to enter it with his whole length. Percy spun them around so he had the woman on top of him placed against the door. Then he positioned her correctly above his dick and moved his hips forward while pressing her against the door. Her spread legs and her visible arousal made it easy for him to slide deeply into her and Artemis groaned in pure pleasure at his penetration.

He was not sure about the speed or force he should use to move and planned on going slow at first, but he remembered her words and her lust-filled eyes, as well as the way how she tightly grabbed his shoulders - it made him overthink. The black-haired boy knew immediately that what she needed at the moment was not slow and sensual sex but a hard and fast fuck - so that is exactly what he did.

He started to ram his cock inside of her with fast and deep thrusts. Every time he did that, Artemis moaned slightly at the feeling of him inside of her. She enjoyed it immensely and the felling of her bouncing boobs as well as the sound his balls made as they slapped against her own flesh made her wish for more - much more. The friction between Percy's dick and her pussy walls was a pure bliss and Artemis admired his stamina as he kept going for what felt like hours without a sign of exhaustion. The goddess had multiple orgasms before the son of Poseidon reached his own climax. He was damn close as she screamed out yet again and squirted on his long shaft, which was deeply embedded between her spread legs as he came too.

It had been a long time since Artemis had felt such a relieve and an even longer time since she had a male to server her needs.

After their interaction, her energy was drained and she knew she would have to rest a bit. The goddess would have loved another round, or maybe even multiple others, but she was exhausted right now and she knew she couldn't handle more. Percy seemed to know this too because he carried her to his bed, placed her on it and left to let her rest.

They would have more of this kind of fun soon.
