After reading the first book of the Lightning Thief series I decided to right a oneshot of PercyXAnnabeth. Just so you know I do not own the Lightning Thief in anyway or any related producuts.

Percy is 12

Annabeth is 12

Chapter One: A Night in Cabin Three

Percy's POV: I was sitting alone in cabin three as usual, thinking about Luke and how I wanted to punch his ass to the gods. I was just thinking about how to find him when someone knocked at the door.

"Why would someone knock at the door at 11:15 at night?" I thought to myself, as I opened the door. Standing in the door was Annabeth, my second best friend at Camp Half-Blood. She was in a white button-down shirt and tattered jeans.

"Hey Percy" Annabeth said in a tone I never heard her use. It sounded almost seductive. "Whatcha doin?" she asked.

I just shrugged and said, "Nothin really." She nodded and came inside. I became hard for some reason, maybe because she locked the door behind her and drew the shades down. "Um, Annabeth, what are you doing? Shouldnt you be in your cabin?" I asked.

"I snuck out to see you Percy" she said before crashing her lips into mine. At first, I severe feeling of alarm overcame me. I WAS KISSING ANNABETH?! Then I thought if I resisted she wouldn't like that very much, so I accepted the kiss.

I broke it long enough to carry her over to the bed, and slip my tongue into her mouth. We tongue wrestled for a while before she won out. Her tongue went over every part of my mouth as I unbuttoned her shirt. She took off my own and her hands roamed over my muscles.

"Well, well, well seaweed brain. Looks like you've been working out" she said in a nicer way than I ever heard her say before.

She kissed me again as I set her shirt wide open, revealing her breasts, unclothed by a bra. I broke the kiss and started massaging and caressing her breasts. I licked the nipples which immediately got hard.

She started moaning when I ran my hands down to her waistline, and undid her jeans. I pulled them down along with her panties. I moved down to her womanhood and started licking. Unknowingly she had taken off my own jeans and my boxers, amd we were both naked.

"Per-Percy" she managed to say, "I GONNA CUM!" She broke out in uneven spasms before releasing her cum. I lapped up what was there and said, "Wow Annabeth you taste good. I'm sure you want to taste it too." I kissed her urgently and then positioned myself at her opening.

"Annabeth, this will hurt for a minute" I said. She responded by pulling me into a kiss, and I entered her slowly. She jerked painfully and I continued into her warm, tight vagina. I reached he virgin barrier and pulled back out. In one thrust I broke past it, while she arched her back, wanting more.

"Percy, go faster" she said in extreme pleasure. I started going much faster and faster. Nearly at my climax I pulled out for one more thrust before screaming, "IM CUMMING!" I released into her and fell back down, exhausted. I managed to utter, "I love you Annabeth" before drifting into the longest sleep ever.

"I love you too Percy" Annabeth said before drifting to sleep just like me.

Little known to them, outside cabin three, Luke was watching through a spell that came through the shades. He growled in anger. "Annabeth is mine! Percy is so dead once I get my hands on him" he said in angry fury.

To be continued….

So what do you think? This is my first attempt so don't hate it too much. REVIEW!
