CHAPTER 1

Jason and Annabeth were trying to keep it down. It was painstaking work, but they managed to keep their heavy breathing on the quiet side and to keep the gasps and groans to a minimum.

Annabeth was currently pressed up against the wall of her cabin aboard the Argo II. It was 11:13 at night, but that wasn't the most noteworthy part of the situation. Because she was stark naked. Her legs were spread wide and her heart was beating fast, just as her face was contorted into a wince-like expression as she struggled to control her erratic breathing and to keep sounds of a more unconventional nature from exiting her mouth.

Jason Grace, son of Jupiter/Zeus and fellow Hero of Olympus stood before her, with his hands gripping her waist as he rapidly thrusted forwards and backwards. His jeans and boxer shorts were down around his ankles, but his Camp Half-Blood shirt remained on. It was beginning to cling to his torso, as perspiration can do that to clothes.

As I'm sure you've realised, Jason and Annabeth were engaged in sexual intercourse and their "engagement" was coming to its end, which was apparent, as Annabeth's breathing became more uneven and Jason began to scrunch up his face and thrust even harder. Annabeth's control began to waver as moaning/panting noises began to emerge from her throat. Jason, wincing with the now considerable effort to keep his own voice down, pumped his erect penis in three long, excruciating thrusts into Annabeth's vagina. After the third thrust, he pushed his penis as far into Annabeth's vagina as he could and threw back his head, drinking in the unbeatable feeling of having his testicles release several ropes of sperm into Annabeth's "pussy".

He slowly came down from his high, lowering his head and opening his eyes to see that Annabeth had reached orgasm too. Her blonde hair was plastered to the side of her face with sweat, her eyes were wide and swirling.

They met each others gaze and held it for a few seconds, before they began to wrap up. Annabeth leaned forward from the wall and Jason removed his hands from her bare waist. He then slowly withdrew his semi-hard penis from her. It was covered in slime and with it came a small trickle of semen, that fell to the cabin floor. Annabeth then released a small sigh, before moving around Jason, to go into the small en-suite bathroom attached to her cabin. Jason knew that she was scraping the sperm from her vagina and wiping away any of his sperm from her thighs before it dried in. Her face looked tired. The guilt normally didn't wait long to set in.

Jason for his part, turned towards the bed and picked up the packet of Kleenex that he had brought with him. He swiftly wiped his dick clean, before pulling up his underwear and jeans. He then walked into the bathroom, to see Annabeth's figure behind the distorted glass of the closed shower door. He could see her bent over, using her fingers to draw out as much semen as she could from her pussy.

It wasn't for fear of getting pregnant, she was of course protected, more that she didn't want it dripping out of her during the day and staining her clothes.

He wet his tissue under the tap and returned to where a blob of his cum lay quickly drying on the cabin floor. "Why does this damn stuff have to dry so quickly?" he muttered to himself. He was pretty sure that a tiny stain on the floor wouldn't raise any suspicions, but Annabeth was overly cautious about these things. At that moment Annabeth emerged from the bathroom. She had donned her grey fluffy bathrobe and let down her hair, which now fell loose around her shoulders.

She sat down on the bed across from him. "You going to have a shower?" he asked her. "No, it's too late" she replied. He nodded and looked back down at the tissue. Noticing, she said "Hey you can leave that. Go on, go back to bed I can clean it." "No I don't-"

"Really, I got the powerful stain remover from the stores yesterday and I want to really go at it." Jason jerked his head and frowned slightly as he stood. "Y'know, I'm really not sure why you're going to so much trouble…" he faltered as he recognized a familiar expression crossing her face.

"Jason; she said slowly and exasperatedly; "have you any idea what it would be like if we were to get caught? It wouldn't just be Percy and Piper getting their hearts broken, it would pretty much doom our whole entire quest! The world is in the balance here and this whole thing really is…" Now it was Annabeth's turn to falter. She didn't need to say how much of a bad idea this whole thing was. She simply watched him, calculatedly.

Jason was glad that Annabeth wasn't his girlfriend. Sure, the sex was great, but she was much too smart and much too strong-minded for his liking. He could see why Percy adored her but she wasn't his type.

"Anyway…" he said, turning towards the door. It was kind of awkward between them now. Their chemistry wasn't great outside of the bedroom (in the metaphorical sense of course.)

"I guess I'll see you". She nodded, her eyes still stormy. And them, with a small smile, he opened the door and crept back across the hall and into his own bed.

Hello reader! I guess this is like a kind of intro into a story I've wanted to write for a long time. I'm not sure exactly how I'm going to format it or whatever, but know that most chapters will be longer and of better quality than this one. I'm totally open to suggestions and WILL read any reviews, so if you have any suggestions please feel free to leave them in the review section. I feel like I should state now, that I am a HUGE fan of Percabeth. Literally, I am a bigger Percabeth fan than you are. However, I for some reason find the idea of a Jasabeth affair to be really hot and fun to write about and have been frustrated with the complete lack of Jasabeth fanfics out there. That's partly why I decided to write this story, so if you share my feelings on Jasabeth, I would love to hear your suggestions on where this story could go, or on any sex scenes that you want to see written about. But if you want to call my a lunatic pervert, then that's fine too.

Anyway, thanks for reading. Peace out.
