Summary
     The story takes place during The Lightning Thief, when Percy,
     Annabeth, and Grover have just killed Crusty, the waterbed salesman.
     Percy releases Grover, but decides to have some *ahem* fun with
     Annabeth. Sexy times ensue.
Notes
     I'm fully aware that they're 12 here. I had the image of a 15/16 year
     old Percy and Annabeth in my mind though. This fic is a product of me
     re-reading the series, and so, I already had the personalities of
     their older selves in mind, and wrote with those as a huge influence.
     Basically, I wrote it as if they were 15/16 instead of 12, but still
     had about the same relationship as they did during The Lightning
     Thief. Plus, something about the pretty much abandoned water bed
     place just drew me in... Anyways, I wrote it with the image of them
     both being 15/16. Does that mean I should use an AU tag?
See the end of the work for more notes
Crusty crumbled into dust and Percy walked over to Grover, slicing the ropes
off of his body. Grover sat up, rubbing his wrists and then grabbed a golden
drachma out of the backpack.
“I’m going to send Chiron an Iris message,” he said. “Let him know where we
are.”
Percy nodded and as Grover trotted out of the building, then snapped his
fingers and said “Ergo.”
The ropes stopped stretching Annabeth, and Percy told them, “Loosen up. But
keep her where she is.”
The ropes obeyed, and Annabeth looked up at Percy, confusion and irritation in
her eyes. “What are you doing, Seaweed Brain?” she demanded, looking up at
Percy.,
Percy lost himself in her beautiful, grey eyes and made a decision. His mind
shifted from just bothering Annabeth to doing something that he never would
think of doing, were she unbound.
“Annabeth,” he said, sitting on the edge of the bed. He leaned in. Annabeth,
realizing what he was about to do, began to protest.
“Wait, Percy, you can’t. We’ve only known each other for mnnngggfff-” protested
Annabeth, her words cut off by Percy’s lips against hers. Her eyes widened as
she struggled against it, but soon she relaxed and Percy pulled away.
She looked away, blushing “W-w-what was that for?”
Percy didn’t answer as he sliced through the ropes holding her with Riptide. As
soon as Annabeth was free, she slapped him, her entire face flushed crimson.
Percy dropped Riptide and felt his burning cheek. He turned his face back to
her and saw her kneeling on the bed in front of him, the blush not showing any
signs of fading.
“Percy Jackson,” she said, still not looking at him.  “You just stole my first
kiss.”
Percy went to apologize, but was cut off by Annabeth leaning in and kissing
him, pulling away just as quickly as she had come in.
Now it was Percy’s turn to blush.
“D-Don’t get the wrong idea” said Annabeth “I only did that because it seemed
like you wanted me to. B-besides, kissing is supposed to relieve stress, and
the whole quest and being attacked by monsters and we only have a day left-”
“Annabeth,” said Percy gently, placing a hand on her shoulder and cutting off
her ramble. She glanced at his hand on her shoulder, then back to him.
“We are both really stressed, so, can we, you know…” he said, indicating with
his hand. “Do that again?”
“Kiss?” asked Annabeth. “You want to kiss me again?”
“Only if you want to,” said Percy, blushing.
“You didn’t seem to care about what I wanted a minute ago,” said Annabeth.
I couldn’t resist a minute ago,” whispered Percy.
Annabeth glanced back at his lips and said, quietly, “We could do it one more
time.”
Percy gave a small nod and then paused before he leaned in, Annabeth mirroring
him. Their lips met awkwardly, and their kiss lasted longer than the first two.
They were both blushing as they pulled away and looked at each other, their
faces an inch apart.
“One more,” said Percy, smiling at Annabeth.
“One more,” repeated Annabeth, returning the smile and kissing Percy, wrapping
her arms around his waist.
This time, when they pulled apart, they were both hugging each other tightly.
Annabeth’s head rested on Percy’s shoulder, and Percy enjoyed being close to a
girl he wanted for the first time.
Annabeth looked at Percy, bit her lip, and then straddled Percy’s lap, facing
him. Percy became completely aware of Annabeth’s body. He could feel her arms
around him, her heart pounding, her breath in his ear, her breasts against his
chest, her butt on his crotch. Annabeth was just as aware of Percy as he was of
her. She could feel everything about his body; most noticeably the hard bulge
pressing into her butt.
The two kissed again, and Annabeth gently flicked her tongue across Percy’s
lips as she pulled away. Percy got the hint. As they kissed again, he opened
his mouth a little to let Annabeth gentle probe inside with her tongue. As
their kiss deepened into something more passionate, their tongues danced around
each other.
They were holding each other tightly, and when Annabeth pulled away, she
shifted in Percy’s lap. Percy jolted at the stimulation and Annabeth smirked,
kissing him again and gently moving her hips as she did so. After a few
seconds, Percy started to move his hips with hers, and the two of them started
to lose themselves in the pleasure.
Their lips parted, and Annabeth pushed Percy down onto the bed, taking his lips
again, now frantically grinding her crotch against the bulge in Percy’s pants.
Percy moved his hands to the small of her back, then up into her shirt. He
moved them up and over her bra strap, tracing circles in the space between her
shoulder blades. He slid his hands down her back, tracing her spine. Annabeth
shivered at his touch.
She gasped when Percy suddenly grabbed her butt, then began to grope it,
feeling it in its entirety. In response, Annabeth moved her lips to his neck,
alternating between biting and sucking.
With his neck and crotch being assaulted, Percy got bold. He grabbed her
Waterland Park t-shirt and pulled it up. Annabeth lifted her arms over her head
and let the shirt to come off. She was now kissing him with her bra exposed,
and Percy’s eyes drank in the sight of her bare skin. Annabeth then pulled off
Percy’s shirt, and her skin felt electric every time it touched his. Percy felt
her supple breasts against his chest and he couldn’t wait any longer.
“Annabeth…” he groaned. She knew exactly what he wanted, so she pulled away,
letting him inspect every inch of her skin.
Annabeth turned and sat on Percy’s lap, with her back now against his chest.
Percy moved his hands onto her stomach, but was heasitent to move them any
higher.
“Percy” said Annabeth, her nervousness and excitement making her voice shake,
“I want you to.”
Percy’s hesitation evaporated. His hands moved up and he cupped a breast in
each hand, squeezing gently. She moaned softly, which drove Percy even crazier.
He pushed her down and kissed her, loving how passionately she kissed back.
Percy pulled away and looked down at the half naked Annabeth lying on the bed.
He wanted to ravish her. He scooped Annabeth into his arms. She blushed as
Percy kissed her, and then let herself be carried to a bed with a canopy and
thick black curtains. Percy placed Annabeth on the bed, and then climbed in
after her.
Annabeth pinned Percy down and pressed her lips to his. The two kissed,
committing the taste to memory. Annabeth pulled away from him, whispering,
“We’re still a little overdressed…”
 
Percy swallowed hard, and pulled his pants off,throwing them over to the corner
of the bed.
Annabeth looked at the bulge in his boxers and bit her lip. She pulled her own
shorts off, and tossed them on top of Percy’s.
The two looked at each other, and this time, Percy pushed Annabeth down,
claiming her mouth as they frantically ground their hips together.
Percy reached under Annabeth and unclasped her bra, which she then threw away,
keeping her breasts hidden against Percy’s chest. Percy gulped and Annabeth
smirked, whispering into his ear,
 “Do you want to see them?”
“I really want to see them” said Percy.
Annabeth kissed him and then smirked again as she pulled away, letting Percy
stare at her bare breasts. Seeing her full blush, Percy kissed Annabeth
tenderly, and then started fondling her breasts. He brought his lips to them,
sucking one of her nipples into his mouth. Annabeth whimpered, and as Percy
began flicking her nipple with his tongue, he began tweaking the other with his
hand. Annabeth moaned and shivered, letting Percy have his way with her.
 After a few minutes of pleasure, she pulled away and got up, pushing Percy
back. He fell onto his back, and before he could do anything, Annabeth pulled
his boxers down and his cock sprung free. She was kneeling in front of him now,
and looked up into his eyes.
Then, she reached her hand out and gingerly grasped his shaft. It was Percy’s
turn to moan now. She slowly pumped her hand up and down, and as Percy closed
his eyes, she pulled her hand away. Percy was breathing heavily, and gasped
when he felt something hot and wet wrap around the head of his penis. He opened
his eyes, and saw Annabeth with his cock in her mouth. She looked up at him,
pushed a strand of blonde hair behind her ear, and then began bobbing her head
up and down, flicking his tip with her tongue. Percy couldn’t believe his eyes
as he let Annabeth suck him off. She bobbed her head faster and faster and
Percy moaned,
“Annabeth. Annabeth. I’m going to cum.”
She bobbed her head even faster at that, swirling her tongue around the tip. As
Percy exploded into her mouth, she swallowed his cum, then sucked every last
bit of it off of his dick.
Annabeth moved beside Percy and rested her head on the pillows there. With a
lustful look in her eye, she took Percy’s hand and moved it to her crotch.
Percy could feel the warmth and wetness of it through her cotton panties.
“I’ve gotten really wet,” whispered Annabeth, surprised at the words that had
just come out of her mouth.
Percy grinned and rubbed his hand along her slit. Annabeth moaned. He sped up
and she started to grind her hips into his hand, letting out soft, breathless
gasps. Annabeth bit back a cry, and Percy stopped as he saw that she was
getting close.
“Why did you stop?” she asked, panting.
She knew the answer as soon as Percy skimmed her panties down and pulled them
off of her.
He kissed his way up her thighs and stopped right before he reached her
entrance, staring at Annabeth’s most private place. He ran his tongue over it
and Annabeth shivered at the contact. He ran his tongue up and down a few times
and then flicked her clit, now a hard bud. She clenched her vagina at that.
Then, Percy pushed his tongue inside, fucking her with it. He alternated
between attacking her hole and her clit and soon, Annabeth was grinding her
hips, moaning, only this time,she was grinding into Percy’s face.
“Oh gods, I’m coming,” she screamed, as she bucked her hips desperately, her
juices flowing out.
She lay panting as Percy moved up and kissed her, then rubbed his member along
her entrance.
“Be gentle,” said Annabeth, love and longing in her eyes.
Percy kissed her more tenderly than he had before and whispered, “I will be. I
promise.”
He pressed against her entrance and slowly slid in. Annabeth winced.
“Are you okay?” Percy asked, gritting his teeth.
“Yeah,” she said, “I’m fine.”
In reality, Annabeth felt like she was being stretched open more than she had
ever thought possible.
Percy nodded, not calling her out on her brave front, and pushed forward, his
dick pressing against her hymen.
“Annabeth, should I keep going?” he asked.
Percy looked into her eyes, searching. Then Annabeth pulled Percy into her
chest. “Take me,” she whispered into his ear.
Percy thrust his hips forward and tore through her hymen, his penis sliding
into her incredibly tight hole as he filled her completely. 
There were tears welling up in Annabeth’s eyes, and Percy kissed them away.
“I’m sorry,” he whispered.
“It’s okay,” said Annabeth, taking a breath. “It had to happen, one way or
another.”
Percy nodded and kissed her again, his tongue dancing with hers.
“You can move” said Annabeth, taking a deep breath. “Slowly.”
“As you wish, princess,” he whispered into her ear.
Annabeth liked that; especially considering the fact that Percy was currently
deep inside off her.
He slid out a touch, then back in, gently and slowly. After a little while,
Annabeth’s moans of pain turned to those of pleasure.
“Faster,”  pleaded Annabeth; breathless, desperate. Percy sped up his thrusts,
and soon they were both sweating.
Percy pounded Annabeth, her walls wrapping around his member.
“F-Faster,” said Annabeth, breathing hard.
Percy kissed her as he sped up even more, and their tongues twirled around each
other. Then, Annabeth threw her head back and gasped, “I’m cumming. I’m
cumming!” She screamed as she reached her peak and came hard, grinding against
Percy. He peppered kisses on her neck and chest as she recovered. 
Annabeth caught her breath for a minute, and Percy pulled out of her. He kissed
her gently. Annabeth glanced down at Percy's cock, still rock hard, and got on
all fours, with her ass in the air. She spread her lower lips with her fingers,
looked back with hooded eyes and said “Fuck me, Seaweed Brain. Fuck me hard.”
Percy moved behind her and slid his whole length into her at once, making her
cry out. This time, he didn’t give her time to adjust, just fucked her hard and
fast. Annabeth was still sensitive from her climax, and came again and again on
Percy’s dick, as he pounded into her from behind.
“I love you” she cried out between gasps of pleasure.
“I love you too. So, so much.” panted Percy, as Annabeth came yet again on his
dick.
He sped up even more and then moaned, “Oh gods, Annabeth, I’m going to cum
soon.”
“So am I,” she gasped. “Together! I want to come together!”
 “Oh gods yes. Fuck yes. I’m going to cum Percy, I’m going to cum!” screamed
Annabeth.
“Me too,” groaned Percy.
“Inside,” screamed Annabeth, I want you to cum inside me!”
The coil inside Percy snapped as he pounded into her. Annabeth screamed as she
came, her hole clenching his member as Percy blew his load into her womb.
The two panted heavily as Percy pulled out.  
Annabeth was blushing, but she had a satisfied look on her face.
“Do you really love me?” asked Annabeth, a tad fidgety.
“I really love you,” replied Percy, kissing her cheek.
Annabeth relaxed and fell into Percy's arms.
“I’m so happy right now” she said, her head resting on Percy’s chest.
Percy tightened his arms around her as they both enjoyed the afterglow.
“We still have to finish this quest,” said Percy quietly, not wanting the
moment to end.
“I know,” said Annabeth, her hand finding his. She held it tightly. “It’s
written in our fate.”
In the muted light of the canopy bed, Annabeth drifted off to sleep, listening
to Percy’s heartbeat; slow and steady, like the rush of waves against the night
shore.
“Guess what?” whispered Percy.
Annabeth murmered gently in her sleep, and Percy smiled.
“I love you, Wise Girl”
