Disclaimer- I do not own Percy Jackson or any other characters associated with the series. (or Heroes of Olympus for that matter)

Annabeth sat up in her bed on the Argo II. She had just fallen into a fitful sleep when she was hastily awoken by a strange noise. It was the night after Percy and her had gotten out of Tartarus and she couldn't have been more thrilled to be laying in a comfortable bed in a safe environment. Still, she couldn't sleep. Her memories of Tartarus were still fresh in her mind: the darkness that had consumed her body, the fire river water that had scorched her throat, the monstrous creatures that had loomed over her and spread total and utter despair through her soul. No one forgets something that traumatic that easily. Suddenly, the strange noise appeared again. It sounded like a heavy creature quickly scuttling across the floor. The noise got louder and louder as the creature approached Annabeth's bed. Annabeth looked around her moonlit room and saw nothing. Maybe I'm hallucinating, Annabeth thought. Then, a hairy, heavy limb hit Annabeth in the chest.

She fell back as the force pressed on her and her head slammed into the mattress. Gasping, Annabeth reached for the knife she had placed on her nightstand before bed, just in case there was some unexpected attack on the Argo II. The irony was impeccable. The creature, however, knocked the knife away and moved closer onto her chest, making it so Annabeth could hardly breathe. She looked around frantically for an escape.

"You thought you were the only one who knew about the door?" the creature sputtered into her ear. Annabeth could recognized that voice anywhere.

"Arachne." Annabeth muttered. She could feel its hot saliva on her face. She rose her hand to her face to wipe it off when the stench of freshly cut flesh hit her. The spit on her face was not just saliva, it was also mixed with a large quantity of blood. Annabeth's fear doubled. Who had Arachne killed?

"You knew my weakness, princess. Pride. However, I also know yours." Two of Arachne's many limbs hoisted a body onto the bed. A limp body with bloody black hair and blank green eyes.

"No" Annabeth whispered as she recognized the body. It was Percy. Annabeth's heart hammered in her chest. She strained against the monster's weight to hold his body but Arachne had pinned her arms to her sides. Arachne moved his body closer so Annabeth could have an unobstructed view of him. There was a gaping, bloody hole where his heart should've been. "NO!" Annabeth yelled. She couldn't tear her eyes away from him, hoping he would move. Yet she already knew, he was gone. Then, she cried out a sound of utter defeat. Without Percy, she could not function. Without Percy, she might as well be dead. He was her foundation in the literal sense. He had fallen into Tartarus for her because he "wasn't going to let her go again" but he had left her on this world. He had let her go. She screamed in terror again.

Arachne smiled with glee. "I just wanted to see that beautifully devastated look on your face before I ripped you in half. Have fun in hell." It laughed and prepared to plunge it's teeth into her neck. Darkness.

Annabeth woke up sweating, shaking, and crying. She jumped out of bed and without hesitation, ran to Percy's room to check that he was okay. She walked in and found him twisting and turning in his sleep and she let out a sigh of relief. It was just a dream. However, she still decided to sit on his bed for a while to let her heart stop racing and to calm her breathing. Her demigod mind sure knew how to make her have the worst nightmare possible. What if it had been real? Annabeth shook her head. She couldn't think of that or else she would never recover. She was safe and he was safe, that was what mattered. "It wasn't real" she muttered over and over, watching Percy breathe. Before Annabeth had fully calmed down from her experience, however, Percy jolted up in his bed, breathing heavily. He spotted Annabeth. She was about to sheepishly offer an explanation and an apology as to why she was in his room but he cut her off by lunging across the bed and hugging her as tightly as he could.

"I just-I just had the worst dream" he shuttered as he held her tighter. Annabeth sighed as she smoothed her hands down his back.

"Me too" she whispered.

They sat like that for a while until Percy released Annabeth to look her in the eyes.

"Stables? " he offered.

"Sure" annabeth smiled. Annabeth loved how he had taken it as thier secret place. They walked down there hand in hand, not speaking, knowing they would tell each other what happened soon enough...

It turned out that Percy's dream was very similar to Annabeth's except the antagonist was kelli the empousa instead of Arachne. Once they had each told their stories, Annabeth buried her face into her hands. They were sitting under the glass floor, wrapped up in blankets. Annabeth was leaning back into Percy's chest. "What does this mean?" she asked out loud, not expecting an accurate answer.

"I have no idea", Percy responded. He turned her around and gingerly removed her hands from her face. Then he moved his hands to her cheeks and looked into her watery grey eyes. "But we're ok". She sniffed, looked at the ceiling to avoid the tears threatening to fall, and hugged Percy tightly. Percy hugged her back and felt calm for the first time in a long time. Suddenly though, Percy's mind flashed back to Tartarus, when they found Bob. What if Bob hadn't been there? What if they hadn't found him or if he hadn't helped them? So much luck had allowed them to live. They might not be as lucky next time. Anxiety took over Percy again so he did the only thing that seemed right at the moment. He pressed his lips to Annabeth's, knowing that he might die tomorrow or sometime next week but when he was with Annabeth, he was somehow okay with that. She was the only thing that made him feel sane and safe, regardless of the tasks ahead. He knew Annabeth would always have his back. She grabbed his face and pulled back. From the look in her eyes, he knew she was thinking the same thing. They had each other's backs, no matter what. Percy thought of how much stronger their relationship was, because of Tartarus and his memory loss. Annabeth had neglected helping on a quest when he has disappeared to the Roman camp because she was so focused on finding Percy. Percy had neglected staying on the Argo II to fulfill the prophesy because he needed to be with Annabeth when she was falling into Tartarus. It scared him how much love he had for this one person. It scared him because he had no idea what he would do if she disappeared.

"I love you" he said. "I love you so much."

She smiled, "I love you, too."

He kissed her again and he was filled with desire for her. He felt heat spread throughout his body like a fire. He wanted her.

Never breaking the kiss, he gently lowered her to the blanket-covered ground. Now he was kneeling over her. He ran his fingers over her bare arms up to the straps of her tank top. Annabeth's moved her hands to cover his for a moment before reaching for his back. She crept her hands up his shirt and enjoyed the feeling of his warm skin beneath her palms. He slowly moved his hands to the hem of her shirt. He broke the kiss for a moment and gave her a questioning look. She nodded and arched her back so he could get her tank top off. She quickly tore off his own shirt. Percy thought of when they had first came down to the stables a couple weeks ago. Frank had been mortified when he saw them here. He thought they had done something immoral when really all they had done was sleep. They were on a quest for gods sake! He chuckled thinking of how the tables had turned.

"What?" asked Annabeth, her lips swollen from their kisses.

"Just, a couple weeks ago, we would've never done this. But now..."

Annabeth furrowed her eyebrows, "Never done what?"

Percy froze. Of course Annabeth didn't want to do this - to go all the way. They were on a quest! Just because his feelings changed didn't meant that hers would, too. He internally cursed himself for being such an idiot.

"Uh" he said "Never- Never mind" he started to get off of her when she grabbed his wrist.

"No wait!" she said. "Now I realize what you mean, you mean go all the way. I want to."

"Yeah? "

"Yeah"

"Even though we've never even seen each other naked? " He felt silly saying this but he wanted to make sure Annabeth was completely on board.

She bit her lip and looked away for a second. She looked like she was having an internal struggle with herself. She sighed and finally looked back at him."Percy we were in Tartarus, where it felt like years even though it was only weeks. I'm not even sure what was real and what was only my imagination. I'm not even sure if we're out of Tartarus yet, or if a titian is having me envision this. I need to know that you are real and safe and with me. I need to be with you." She grinned with a little bit of embarrassment. "I also want to thank you for letting go of that ledge for me." She pushed him to the floor so she was on top and kissed him before he could respond.

He started kissing his way down to her throat. "I would do it again in a heartbeat" he murmured against her neck. He continued kissing down her body until he reached the top edge of her bra. He reached behind her to unclasp it. However, he just couldn't figure it out. He took his lips off of her and looked at it in confusion. Annabeth laughed and reached her hands behind her, popped the latch, and removed the bra. She kissed his cheek in adoration. Percy grinned as his cheeks flushed and he flipped her over so he was on top. He slowly moved his hands from her arms to her breasts, keeping eye contact with her the whole time, looking for any sign of distress. All he saw, however, was her eyes darken with desire. He looked down at his hands and marveled at how beautiful she looked and how amazing she felt. He moved his right hand off of her breast and replaced it with his mouth. He licked and sucked her nipple while his other hand massaged her left breast. She moaned with satisfaction and entwined her hands into his hair. Percy smiled, glad he was pleasuring her. He was new to this too.

Annabeth then moved her hands down to Percy's waistline. He stopped massaging and kissing her breasts to watch her. She ran her fingers inside the hem of his pajama pants before slowly dragging his pants down his legs. She looked down at his boxers and saw his erection forming a tent with the thin fabric. Her face showed awe with a hint of smugness, like she was proud she made him feel this way. She looked into his eyes. "Your turn"

She yanked the boxers off of his hips and flipped them over again. She kissed his lips firmly before making a slow beeline with her mouth down over his neck, his chest, his stomach, finally arriving at his member. She kissed it lovingly before taking it into her hands. She gently stroked it, wondering what would happen when she got more intimate but at the same time confident that she knew what she was doing. Percy shuddered at her touch. He couldn't imagine anyone else's hands on him like this. She moved her mouth closer to his member and checked Percy's eyes before taking him into her mouth. Percy felt like he had just eaten a pound of ambrosia. Her mouth moved up and down his member as her tongue explored every crevice of his manhood. Percy moaned in happiness. He could feel Annabeth's smirk on his member and Percy made a new resolve: he would make her moan just as loud.

It was almost like a game between the two lovers, seeing who could bring their partner the most pleasure. However, there was also a much deeper meaning to their elicit relations. They needed to be close. They needed to create this physical binding contract between them. Percy especially felt he needed to prove to her how much she meant to him. He pulled her up to his face and kissed her while he fumbled with her pajama bottoms and her underwear. He tore both articles of clothing off at once and then Percy realized they were both naked together for the first time. Despite his nervousness, this fact only made him need her more. He slid his hand from her hip to the inside of her thigh. He asked with his eyes, is this ok? Her eyes, so dark they were like clouds in the middle of the night now, showed lust as she nodded and, keeping his eyes locked with hers, he slipped his fingers between her folds to discover this previously unknown territory. Annabeth eyes fluttered shut. She bit her lip to keep from moaning, but gasped loudly when Percy rubbed her cilt. Percy shivered from hearing her elicit noises. He did this to her. He moved his fingers over her entrance and hesitated only for a moment before entering a finger inside her. Annabeth's eyes squeezed together as tightly as possible as she moaned again. Percy felt her wetness and his desire strengthened. He flipped her over again so he was on top. He positioned himself at her entrance. He gave her a look and when she nodded furiously, he slowly lowered himself into her. Percy moaned as he felt his cock slide into her vagina. He snapped out of his reverie, however, when he heard a sharp intake of breath from Annabeth. As if she was in pain. He gave her a sideways glance from above her.

"It's supposed to be a little painful the first time", she said her eyes slightly amused as she started into Percy's worried face. "I've done my research. It's fine. Keep going"

Percy nodded but then realized something. This was their first time, and he didn't have a condom. His eyes widened in shock. "Annabeth!" he nearly screamed as he quickly withdrew himself from her. "I don't have a - a"

"A condom?" she smirked. "Oh seaweed brain, this is why I'm the brains in the relationship. I'm on the pill, a goddess-enhanced pill at that. Do you think I would really allow you to do something like this without the necessary precautions?"

He rolled his eyes but was also very relieved, "Fine, you win. Annabeth - 10,457. Percy - 0." But secretly, he was loved her teasing. He loved it when she teased him, mainly because she never acted like this with anyone else. With all of her friends and family, she was very serious. Loving, but serious. With Percy, she let herself go and acted like a normal teenager instead of an adult. He was her own private stress pillow, the only person she told everything to and showed her entire personality to. His love for her almost hurt, it was so intense. He couldn't ever tell her how much she meant to him. He smashed his lips against hers and slowly reentered her body. Annabeth didn't feel pain this time; she felt pleasure. Her nails scraped his back as she sighed and whispered, "faster".

Percy quickened his pace. Pulling in and out, in and out. Annabeth matched Percy's movements by bucking her hips upward each time he thrust down. He looked into her face, her mouth had the biggest smile he had ever seen. This turned him on even more as he went faster. Their hips slammed into each other with each thrust. His member throbbed inside of her and he knew he was close to coming.

Annabeth's breathing turned ragged. "P-Percy I'm gonna- I'm gonna." She moaned as her inner walls clenched around him and she came. Feeling her constrict around him made him shudder and with one last thrust he yelled, "Annabeth!" and came inside of her. In that moment, his mind was empty of everything except the girl smiling in front of him, blonde hair damp in perspiration and thunderstorm eyes full of love. He fell on top of her, breathing hard.

He was laying on her chest, hands on either side of her ribcage. "That- that was" Percy started.

"Yeah" Annabeth agreed, stroking his hair. "It sure was." Then, she stopped stroking him. He looked up and saw her frowning. He instantly went from relaxation and bliss to full defense mode. Was it not what she expected? Was it not good for her?

"What?" he asked carefully. He rolled to the side and propped himself up on his elbow. He would need to be ready for a quick escape.

She chuckled, "Nothing, Perce. Just, well, I finished first. Which means you lasted longer."

He relaxed, realizing nothing was wrong. He rose an eyebrow. "What, was this a competition?" He was teasing her now. That girl was always too damn proud for her own good.

"Well, we'll just see next time." She responded as she rolled onto her side facing Percy. She skimmed her fingers in circles around the small of his back, sending tingles up his spine.

"So... There's a next time?" Percy questioned with a timid smile.

Annabeth smirked and playfully moved her hand down to his butt and giving it a gentle squeeze. "Most definitely."
