Happy reading!

"What are you doing?"

"I'm almost finished" She replied not bothering to tell him exactly what she was doing because it would require an awful lot of talking. She looked up at him from where she was sitting on his desk; he was sitting in his bed with his back to the wall, shirtless and looking bored.

It was their first night at Camp Halfblood after few months out, first they visited Sally and then they went to San Francisco and then they went back to Sally's for Christmas. It had been a fun vacation but they missed this place and it was here were they could truly rest.

Even though it was cold today they did the camp activities they enjoyed so much. Most of their friends were here so a few fun weeks awaited them.

After dinner the night ended with a very quiet and almost romantic bonfire between close friends and they eat marshmallows between cookies and chocolate and talked about normal teenager stuff, like when they were going back to school...every time Percy thought about it he groaned internally, of course he wanted to be back to his normal life but it had been too long since he last touched a book.

After everyone had gone to bed Annabeth sneaked out of the almost empty Athena cabin and crossed the path towards Percy's. They were breaking a rule...but who expected them to sleep separately, seriously? They were far from okay after the war and Tartarus, they struggled but slowly they were getting better. Sometimes they talked about it, other times forgetting and having their minds occupied in other things work best…they were living day by day, helping each other so they could overcome it, their goal was to someday be okay again.

Chiron would simply have to put up with them. Sleeping together and having sex...they deserved much.

They had their first time together about three months ago they could say they were getting experienced, all the awkwardness of the first time gone...

He could still remember how in their second time Annabeth had sat on his legs and examine his...well, erection...like in a laboratory, intently watching it and touching it different ways until she made him came right before her eyes –not for pleasuring purposes at all but just to know how the thing worked –. Despite that it was clear that she knew a lot more (like in everything) about sex than he did.

Sally almost invited them with open arms to have sex under her roof, giving them condoms and stuff (cooler than most moms, she worried about them being safe rather than avoid the subject completely as if sexual activity in teenage couples didn't exist)

Annabeth's dad wasn't as cool with them being alone in a room for a long time so he sent the twins to check on them every five minutes. They couldn't even kiss on the cheek that the twins appeared out of nowhere and started dancing to the "Annabeth has a boyfriend" song.

They had to control themselves a little more when they went to San Francisco. They almost got caught twice and then they had to wait for the house to be empty (like when the whole family went to the supermarket) to be together but always keeping it down, just in case.

Percy had to admit Mr. Chase scared him a bit. He approved of the relationship (of course! Annabeth had overheard him talking to his wife saying there was no one better for her) but Percy felt that sometimes he looked at him with the get-your-hands-off-my-girl-stare and he let go of Annabeth's hand immediately, blushing. The rest of the time he was the coolest, like Percy remembered him, with his war planes and plans.

Annabeth's step mother attempted something like 'the talk' with her but she made clear she wasn't talking about that, and that whatever they were 'doing' she was clever enough to do right but her stepmother didn't leave her alone until she took her to the gynecologist.

Against her will she was examined, but at the doctor's appointment she learned some stuff she didn't know so it wasn't completely useless. She was just being capricious because in her eyes her stepmother wanted to 'play' her best friend but Percy reassure her that she was only being nice.

The doctor told her which pills to take so they were glad to stop worrying about condoms and its effectiveness, Annabeth was always worried about that after having a malfunction once. She thanked her stepmother after that, which took swallowing most of her pride for the past ten years or something.

Cabin 3 was so warm with the heater on and with her laptop on her lap she felt hot, she took her t-shirt off and let it drop on the floor, still sitting on his desk with her legs resting on the chair.

Annabeth could sense his stare so she looked up.

"What?"

"That's...sexy" She looked down at herself forgetting what underwear she had on.

"Seriously? It's a sports bra" Annabeth raised her eyebrows, of all the other stuff she wore on the period of three months this is what he choose to comment on, it was a dull grey and it flatten her chest. Not sexy in the least.

"Is that what is called?" He shifted uncomfortably on the bed and rubbed his neck, his cheeks were blushed "You never wore it before"

"They are good to move, climbing the lava wall with a regular bra it's not very cool, these are comfortable"

"You look good in that" She grinned after a moment of looking at him; Annabeth could tell immediately that he was turned on.

She hoped off the desk and left her computer there. The project could wait...

Percy turned ons were happening all the time and he was embarrassed about them. He didn't mind it now, they were alone in his cabin but he did mind when they were doing nothing related, in public, and suddenly bam! her smell or the softness of her hair just turned him on. The worst thing about it was that Annabeth could tell just but looking in his eyes so she was forever teasing him about it.

They hadn't done it for almost two weeks so she knew he was a little impatient. She went to his bed and sat on his lap putting her arms around his neck, he pulled her closer by her waist.

"This thing turns me on so much" He murmured looking at her gray bra. She rolled her eyes

"Seaweed Brain you're always turned on, don't blame the bra!" She smirked and kissed his lips. "It's the most unflattering underwear; I don't know what you see in it"

"I don't know, it's just...damn sexy" Annabeth rolled her eyes again.

"It's our first time in your cabin." She leaned forward and pushed him back so he was lying down. She brushed his hair backwards and lay comfortable on top of him. His hand went up and down her back.

"Its cozy, I feel at home. Don't you?" She nodded.

"It's also the first time we can be as loud as we want" She whispered in his ear. She pressed her leg between his.

"Mmm" He turned them around so she was against the mattress.

"No, I want to..." She started to protest but was cut with a kiss and Percy smirked.

"My turn!" He said excitedly. Annabeth sighed but let him take her jeans off.

Annabeth wasn't the easiest girl to please really (not that he had done it with anyone else) but after their first time he grabbed her computer and looked up some basics on the internet (deleting the search history later, of course!) he wanted to know how to do it right. If asked he was so denying that he had ever wrote something like 'how to please your girlfriend' on the search bar.

Regardless of his embarrassment while doing it he found some very interesting things he wouldn't have guess on his own in a million years. Annabeth always reassured him she felt good but sometimes she told him to stop —a few annoyed sighs letting him know she wasn't into it— and he couldn't help but be frustrated that she didn't feel exactly like him. Girls had it so different than guys: first rule he learned from a sex site.

The worst was when he came before her. He sometimes (as hard as he tried) couldn't hold that long...he'd curse himself and apologize a lot to her afterwards. Annabeth'd say it was okay (but it wasn't! He should be able to make her come). She would tease him later, 'you're a teenage boy Percy...' He hated so much when that happened.

Apart from those times...he thought he was pretty good (he still had a lot to improve but he managed alright) for the little time they had been doing it.

Annabeth thought Percy was quite good at sex, better than she cared to admit, actually. (She knew how he had looked some stuff up, she was by no means showing him how to delete a browsing history properly but to be honest she was glad he had looked it up, even when their first time wasn't at all bad as first times go he was so naive in some ways and a Kelp Head, he needed the help)

When they had their first time they were still perfecting the make out, they were very new to the whole touching each other business (let alone without any clothes on!)

Now looking in retrospective she thought it seemed rushed, for their style, they were very slow at everything (or Percy was, but really she wasn't in a hurry to do it, either) Annabeth knew exactly why they had done it that day though, it was that feeling of dread, of wanting the other close that the war and Tartarus had imposed on them. Despite that she enjoyed their first time very much, not only on the physical level but emotionally. Annabeth thought she really couldn't get like that with anyone or love anyone that much.

Annabeth pushed him back to a sitting position she didn't want to go straight to it. She looked into his green eyes, sparkling love and that mischievous light he had since he was twelve. Annabeth smiled at him

"Kiss me"

Percy didn't need to be told twice. He kissed her, really slow and tender at first, fitting his lips over hers...Annabeth relaxed in his arms and her hands knotted in his hair loosen falling to rest on his neck. She moaned when he sucked and pulled slightly on her lips.

After two months of learning and experiencing he knew what and how to move on her. It somehow embarrassed her how she could not keep it down whenever he was in charge so she liked to take the lead, to have some control over the feelings on her body. It was kind of a game they had, to see who could please the other the loudest. It was probably her favorite thing about sex (well, beside the obvious) to please him, to see how he couldn't talk properly for a few minutes afterwards, blushed and breathless.

The good thing was that for the first time they were alone, no parents in the next room or anyone, no need to be cautious or attentive.

"We're going to make some good memories here" Percy said while lying kiss after kiss in her cheek, Annabeth scoffed and brought his mouth closer for a kiss. She let him set her back lying on the mattress. He looked down at her mischievously.

"What Kelp Head?" He smiled a little.

"Can I try something?"

"I'm scared" She stated faking seriousness and Percy grinned.

"Don't worry. I think you'll like but tell me if you want me to stop" She nodded. He always made sure she enjoyed so she trusted him. They hadn't tried a lot of things just yet so this might be a change.

"Okay, but after that I-" Percy started laughing.

"You are already thinking about the second round? Woah give me a rest, Wise Girl" She rolled her eyes and punched his arm.

"Idiot"

He started kissing her softly and she intertwined her fingers in his black hair pulling him closer. The kiss turned very passionate when she opened her mouth, her breath mixing with his, and slid her tongue in his mouth. Percy moaned when her tongue insistently sucked and played with his.

He immediately pulled back a bit to look at her; he knew exactly what she was doing.

"Cheater" he murmured with humor when he pulled away completely, if she managed to get to him he would be lost in a second, succumbing to her power.

He moved to kiss her neck below her ear and sucked over the soft spots at the same time sliding his warm hands over her body, making her moan. She put one of her legs over his and grid her hips against his, feeling his hardness.

He went back to kiss her until they both pulled away to catch their breaths.

Annabeth sat up a little and took off her sports bra and Percy's mouth went against her neck again, going over to her collar bone and down slowly, to her breasts. Annabeth hissed when she felt his mouth over one of her nipples, she was so sensitive to that.

She tried to slide one of her hands down his pants but he caught her and laughed against her chest.

"Don't be impatient" He said at the same time while brushing his thumb over her centre, she arched towards his touch but he went back to her breasts.

He tugged at one of her hard nipples with his lips and sucked. She was squirming under him; rubbing their hips together intently making Percy stopped his kisses because of his groans. He needed her so bad.

He went tracing wet kisses down her stomach and he kept his thumbs brushing her nipples.

When Percy's kisses went around her hip and he slid her panties down Annabeth got an idea of what he wanted to try.

"Percy..." She let out when he kissed the inside of her tight and she spread her legs, grateful she had shaved not long ago.

He came level with her face and smile a little, his fingers tips gliding over her inner tights, she was so soft. Annabeth squeezed his cheeks and kissed him.

"I wanted to do this for a while" he managed between kisses. He touch a finger tip down her centre to check if she was wet enough, it dip in easily and she moaned and arched toward his touch.

"Percy for gods sake!" She urged when he slid the wet finger down her leg tracing a pattern. He looked at her mischievously "Stop teasing me" He smirked and went down on her, positioning himself between her legs he sucked on her soft inner tights just to build more anticipation, she groaned frustrated. "Perseus!"

"If this doesn't feel good, tell me" He said and his hot breath hit her clit and her only response was a loud moaned.

He started slowly and unsure with his lips faintly brushing on her clit, kissing it. She moaned his name and he enveloped it all in his mouth just like he read on the internet, positioning his tongue on the lower section of it and like that he moved his whole mouth very slow.

Annabeth was amazed by how good this felt; she let out the breath she was holding.

"Oh" She expected this to feel the same as it felt when he used his fingers but it was another thing entirely. His hot breath ghost faintly all over her

"Feels good" she murmured but not sure if he heard it she encouraged him moaning and arching her back so he went on sucking harder, he did this for a while but after a few moments it became unbearable.

"Agh!" She groaned and at first it seemed a sound out of pleasure, she gritted her teeth and claw on his shoulder. "Percy! Oh gods, Oh! Too much" And he stopped worried that he hurt her, he looked at her and she said breathless "too- sensitive"

Right! He read about that too! 'Not too much direct contact' He wanted to hit himself in the face, he remembered now. He slid his tongue down and her wet folds opened and he started licking slowly to wait for her reaction.

"Hmmm" Her fingers intertwine in his jet black hair and pushed his mouth closer against her. He took it as a good sign and kept it up with more confident strokes but ready to pull away if she felt the need to. "Oh!"

"Good or bad?" He asked pulling away.

"Good good!" She replied and pushed his face against her. Annabeth had such a particular smell...he liked it. He went on licking and sucking softly

"Keep going...that way" He smiled against her and worked his tongue in slow movements in and out, the way she encouraged him to. He pressed one arm over her hips to stop her from wriggling so much and traced her nipple with the other hand.

Annabeth let out a high pitched cry when Percy started sucking harder, she tighten her fingers in his hair and grabbed a handful of sheets. He went towards her clitoris licking slightly and she cried out again. He was so glad he attempted that here and not a month ago in her parents' house when he wanted to. He'd been wanting for a while; he thought it was so hot.

He traced his tongue right under her clitoris but not touching it directly and Annabeth rewarded him with more cries.

"Percy! Oh gods!" Her back arched involuntary and he sped up his movements sticking his tongue in and out faster, then in circular movements holding her hips down the mattress.

She came crying out his name after a moment, her orgasm breaking in her lower section sending waves of pleasure all over, numbing her mind. It was one of the best ones she ever had. He ride her down from it still sliding his tongue slowly around. She cursed loudly and sighed letting her eyelids drop.

He came level with her face and wrapped his arms around her, she buried her face in his chest, breathing hard, trying to regain her senses. That was a tick and a star for oral, he couldn't stop grinning.

"That- was good." She managed after a moment and he laughed and kissed her temple. "So good"

"I'm glad you liked it. I enjoyed it too" He grinned at her cockily. "See what I did there? I managed to find a balance as you said it was too much at first"

"Yeah yeah you were amazing" She rolled her eyes at his proudness but meant it.

"I can't wait to do it again" Annabeth smiled and brought his mouth towards her, the taste of his mouth was weird but it was hot at the same time. It made her want more just thinking about what he could do with his mouth.

She kissed his chest and undid his jeans; he kicked them off alongside his boxers, letting his hard erection to spring free. Annabeth grabbed his throbbing erection and stroked it slowly pulling the sensitive skin back and forth.

He moaned in pleasure and nibbled on her neck; Annabeth laughed and pushed him away.

"Don't do that Seaweed Brain"

"Can I do this?" He snaked his hand down and rubbed his thumb and forefinger over her little knob.

"Well..." She sighed in pleasure, wetter than before. She grabbed his hand and moved it slowly against her at the same time as she sped her movements on his erection.

He moved over her "I'm going to come if you keep that up" She grinned and guided his hard erection instead brushing his tip to her entrance.

Slowly he pushed inside her. "Ahh! Two weeks are too freaking long" Her grin widen as he spread her legs grabbing her tights and locking them behind his back.

"Think about how good you feel now" She said and he pushed in deeper, she was tighter than usual for her last orgasm.

"There's nothing- I can't- think of anything else. Gods"

"I know, your mind is very limited, you can't think a lot stuff at the same time" He always wonder how she could keep such a steady voice while they were having sex.

"Haha- very funny Wise- Girl" Annabeth smirked and he started trusting inside of her "you feel so- damn!" Her nails dug in his back, he started out very slow, and Annabeth thought it was more enjoyable that way, long slow strokes that went from very deep inside her to touch her clit with his tip and all the way back in.

"Oh, my gods" She blurted out after a minute.

"Good or...bad?"

"Shut up" he laugh breathlessly.

"So bossy- I like it-I like bossy girls" it was her time to laugh

"Yes? Then get moving!" he shifted the next trust and made her grit her teeth.

They kissed each other and then he moved his mouth to kiss her neck and to whisper cute nothings mixed with moans in her ear like he always did. He loved the little sounds coming out of her lips.

"Go faster" She urged arching her back. Annabeth had to remind herself she didn't have to bite her lip and swallow her moans They were alone in his cabin.

Percy groaned and obliged to her request. "Annabeth!" He closed his eyes when she started meeting his hips with every trust. How can something feel this good?

Percy worked harder to get her to come before him, he was dangerously close. He put his hand between their sweaty bodies colliding together and used his index to rub her clit.

Annabeth let out a low sound and he knew how she was right there.

She encouraged him to keep doing it like that and when Percy felt it safe he let go as well. A second later it was over for both of them. They took in their pleasure loudly, something they couldn't do before.

"Annabeth for gods sake!" He groaned with his face buried in her neck. Annabeth let out a little choked laugh when she heard a series of muffled curses between ragged breaths.

That was a good one.

She tried to catch her breath but supporting all Percy's weight was hard, he moved away from her when he noticed she was uncomfortable.

"We're getting quite good at this" She managed and he pulled her to his arms.

"You bet" He replied faltering. She sighed with her head in his chest. Annabeth brushed his sweaty hair back and he let out a content breath. They stayed silent for a few minutes, their hard breathing filling the room

"Such fun weeks ahead of us Wise Girl"

"And then school"

"Agh don't mention that!"

"Sorry if some of us want to graduate and actually do something with our life. You don't make a very good living out of being a hero"

"So they tell me"

"Come on! It'll be fun" She shook his arm excited and then propped her chin on her hand in his chest.

He rolled his eyes, Annabeth was the only one who could describe high school as fun, for most people it was a nightmare...killing monsters yeah he could do that but facing trig class no, not really...

"I'm so failing" he grumbled and she laughed

"We haven't even started Seaweed Brain!"

"Can we like not think about that nightmare now...let's just chill and enjoy camp with our friends and..." He wriggled his eyebrows suggestively

"And...?" She asked raising her eyebrow.

"And enjoy my sweet cozy little cabin and have lots of sex"

She scoffed "Uh-huh yeah sure Perseus."

He laughed and wrapped his arms around her small waist but she pulled away and sat on the bed

"Don't go" he whimper like a kicked puppy. "Let's cuddle"

"No"

"What is lovemaking without cuddling afterwards?" She looked at him amused. He was a true cuddler.

"I'm hot" she replied getting all her blonde locks up in a bun she tied with her own hair.

"Yeah, I know you are" she rolled her eyes and stood up and grabbed her panties from the floor. He watched her slender figure go around and couldn't help but smile.

"I meant the room is too hot with this heater and you're sticky with sweat"

"I don't know if that's particularly sweat"

"Ewww" she made a face scrunching her nose and then went to his closet and grabbed a towel. She cleaned between her legs and then threw it at his face, he laughed.

Annabeth put her panties on and fished an old T-shirt from his closet and put it on. She grabbed her computer and sat on the floor, that was cool to touch, with her back to the bed.

Percy finished cleaning himself and threw the towel to the laundry basket, put his boxers on and propped his chin on his hand and watched her.

She was already typing some numbers on a program and a mass of lines came to life before her and she studied them and changed them...gods only know what she was doing.

He watched her profile, her lips set on a line; her grey eyes traveled all over the screen, determined and calculating; her long eyelashes; the rising and falling of her chest with every breath; loose curls lay on the nape of her neck...one curled really perfect and soft, he almost extended his hand to touch it but retrieved it because he didn't want to ruin it.

He leaned forward and smelled her neck moving the strands of blonde hair slightly...she smell so divine with that mixture of sweat and her own perfume. Annabeth grabbed onto the sides of her computer when she felt his breath against her neck but he pulled away quickly and continued to stare at her with his chin on his hand.

"What?!" She demanded annoyed after a few minutes, still staring at her computer screen. Annabeth hated when he distracted her.

"Nothing, you're just...beautiful" he let out without thinking.

She kept staring at the screen but cheeks flushed a little. His words didn't sound rehearse or forced and he said them in a way that she wanted to believe him.

"Annabeth are you blushing?" He asked with mock horror.

"It's the heat" she replied.

"Yeah, it's the heat" he smirked and kept staring at her from his place on the bed thinking how she looked adorable when she blushed.

She didn't turn to look at him but he could swear he saw a tiny smile playing on her lips.

He stood up and walked across the room and opened half the window. A gust of fresh sea air came in, cooling the room rapidly. He stood there a minute, breathing it in and went back to the bed, without closing it.

"So you stop being so hot" he explained smugly when she looked at him over her laptop. He lie on the bed again and could see how the hair on her airs stood on end as the air rushed in, it was January, of course the temperature outside was that cold.

He pulled the covers up, cozying under the duvet, sighing for the warmness and closing his eyes. Percy waited to see how much time she lasted sitting in the floor with only a t-shirt on.

After ten minutes or so she was already cold. Annabeth shook her head, smiling, at her boyfriend. She sighed too, but in defeat, and stood up and turned off the bedside lamp.

She saw Percy's triumphant white teeth smile in the dark… She lay down next to him and he immediately wrapped his arms around her.

"See how nice this is Wise Girl?" He murmured against the skin of her neck, his legs fitted between hers.

"I hate you" She laughed and rearranged her pillow, sitting up a little and bringing her computer to rest on her stomach

"What?! No…don't work on that now" he tried to close her computer but she moved it away.

"Yes, come on, we both win"

He grumbled but decided this was the best arrangement.

"Now hug me, I'm cold" and it was true, the air outside the blankets was cold. He knew that as soon as it turn too cold she was going to nudge him to go close the window for her.

"Yes, ma' lady"

She let out a very girly giggle when he tickled her side. She tried to move away from his wondering hands which almost made her drop her precious laptop. Annabeth shoved his shoulder playfully but then scooted closer to him, he pressed his face against her shoulder, and her curls tickled his cheek. She resumed typing codes and numbers and whatever and soon her fingers on the keyboard lulled him to a sleep, dreamless for once.
