This is so wrong. So, so wrong, her mind continuously screams at her... but her body betrayed her conscious.

Her wrist were currently above her head held firmly in Percy's bigger hand, as he pinned her against her bed while roughly attacking her neck... that is definitely going to leave a mark, and Annabeth will most likely be wearing turtlenecks for the next few days. She moaned in pleasure, as his bare chest rubbed against hers. She was merely in her jeans and bra at this point, and the feeling of his strong body covering hers made her eyes cloud in desire.

It was past midnight, about half an hour after her and Piper had decided to head to bed, she had gotten a text from Percy asking if the coast was clear. At first she had wanted to ignore his text, but as she lay in bed... she decided against her better judgment to ignore him. And now, here they were... tangled in bed, just across from Piper's room.

He groaned in desire as his mouth lowered to her cleavage, and Annabeth's arms struggled to free to wrap her arms around him, but he didn't allow it and kept her wrists pinned above her and smiled.

This had been going on now for the last week; they would send each other a text and meet at various private places to hook up. This included the back of his car, an empty janitors closet at school... but by far the hardest was their apartments. He lived with Jason and she lived with Piper... the last two people that could catch wind of this affair. So, in public, Annabeth would go back to ignoring him and pretending like he doesn't exist.

It had gotten ridiculous how much their physical pull controlled them. A day hadn't gone by since that day in the elevator that they didn't find ways to be alone like this. No matter how stupid or risky it had become. Annabeth knew there was no rational explanation as to why she was hooking up with her best friends ex like this, there was no justification. But, she had suppressed the guilt so far down, because she knew that if she let it climb up... she wouldn't be able to continue this. And, as wrong as this is, she had become powerless to it. His body against hers felt so right. It felt like a different world, where their relationships and problems didn't exist. It was simply physical needs and satisfaction.

It was an escape.

He finally released her wrists as he slowly unbuttoned her jeans, before his desire filled eyes met hers and he smirked.

He knew she was powerless, and she moaned for him to continue.

His lips brushed against her ear, "You'll have to be really quiet, babe." he whispered hoarsely, causing shivers to run down her spine, before capturing her lips passionately as he unbuckled his jeans.

ΩΩΩ

The next morning, she sat across Piper on their stools at the counter eating cereal. It was hard for Annabeth to meet Piper's eyes, as Piper chirped happily about something that happened in her early morning class. Annabeth only tuned in when she heard mention of Jason's name.

"Wait, what happened?"

"Well, our college holds a winter formal every year. It's held by the student union as a breather after exams. It's always been amazing and we've gone every year. But, you have to have a date in order to attend. Last year I went with Percy..." she trailed off momentarily, and Annabeth felt a pang of guilt against her chest, "But since this year that clearly won't be the case, and I didn't want to go with some random guy – but also didn't want to miss this years formal, Jason agreed to take me." she grinned.

Annabeth felt her eyebrow rise in amusement, "So, you and Jason going to a formal together, huh?" she teased.

Piper rolled her eyes at her, "Obviously it's not like a date or anything. More like... accompanying me because he knows how much I love this sort of stuff."

Annabeth still grinned at her, "Well, isn't that awfully sweet of him." knowing it wasn't just the generosity of his heart that had Jason offer to take her to the formal.

Piper laughed, "He is, isn't he?" as she got up taking both their empty bowls to the sink, "So, we'll need to get you to go with someone, too. There is no way I'd let you miss the formal since it's your first and final year here!"

Annabeth laughed hesitantly, "No, Pipes, I don't want to go with some random guy."

"It doesn't have to be random. I know for a fact that a friend of Jason's would love to take you."

Annabeth turned to look at her, "What friend?"

"Will Solace from the football team! I know you've met him a few times at other events and at Jason's place. And, he is pretty cute."

Annabeth got up from her spot and grabbed her purse, "I'm not really all that into formals, anyway. So I would really rather just have a quiet night in." and have the apartment to myself for a few hours.

Piper shook her head, "Jason and I knew you would say that, so we took the liberty to tell Will that you'll go with him." she grinned proudly.

"What? Piper!" Annabeth exclaimed.

"This is the last time you, me and Jason will be in school together! Last year of college, and since we're lucky to all be here together, there is no way we'll go without you. Come on, Annie! Give it a chance! The formal is honestly so amazing! So much fun! And, this is probably the last school formal we'll ever get to go to together!"

Annabeth sighed, "What if he's like Luke? How can I trust some random guy I don't even know that well?"

"Obviously he isn't a slime ball. He knows you're practically Jason's sister, and he's actually good friends with Jason and know he'll get killed if he tries anything. And, all four of us will be together the whole time anyway; it's really just like a ticket in the door!"

"Alright, fine." Annabeth agreed unenthusiastically.

Piper squealed in excitement, "Awesome. I'm texting Jason to let Will know!" she said, pulling out her phone.

"I thought you guys already told him?" Annabeth questioned with narrowed eyes.

Piper winked, "We wouldn't trap you like that."

"Feels like I'm getting trapped now." Annabeth muttered dryly, heading for class.

About half an hour into her lecture, she noticed her phone light up. She felt a half blush remembering the events of the night before, before opening the text.

Lake – 15 minutes?

Annabeth frowned; she looked back at the lecture that was still progressing slowly. Annabeth shook her head, before texting back;

I'm in class!

Percy read her reply, frowning. Crap.

He grabbed his bag from the locker in the gym, running a hand through his wet hair. He had just showered after one of his swim practices, and was hoping to meet Annabeth before heading back to his apartment.

Jason slapped him on the back as he came to stand next to his locked, his bag slung over his shoulder, "Let's go grab some food on the way back. Coach killed us out there."

Percy nodded as they headed to the food court of the college. Percy wondered how Jason would react if he knew that he was hooking up with someone he considered a sister. Percy remembered how weird Jason had been when he found out he was dating Piper, and she was just his friend.

Jason looked over at Percy as they took their food, "Oh, Perce, I just wanted to let you know.. I'm taking Piper to the winter formal thing; I just wanted to make sure that wouldn't be weird for you? We're going as friends, obviously, but I still don't want it to seem like I'd be hiding that from you."

Percy was a little surprised, "Yeah, Jason, you don't need to ask me."

Jason shrugged, "She's your ex-girlfriend, dude." he reminded.

"Yeah, but she was your friend first." Now, Percy felt kind of bad about not telling him about Annabeth. But, what he even say? Hey, I'm hooking up with the girl you call your sister – no strings attached.

"But, yo, are you coming to the formal?"

"I'm not really seeing anyone. Isn't that kind of a date type thing?"

"Dude, you're joking. I know you wouldn't have trouble getting a date." Jason snorted.

Percy smirked, yeah, but you wouldn't approve of the date I would bring.

"We'll see."

That's when one of Jason's teammates joined their table and bumped fists with the two of them, "Brutal practice today, right?"

Jason laughed, "Yeah, because we're getting so close to the game."

Will stretched out, "Exactly. Which is why he should let us rest. I honestly don't know how I was able to walk off the field after practice."

Percy tuned them out again. If Jason and Piper both went to the formal, that would mean his and Annabeth's apartments will be empty that night.. that will be awesome. He thought to himself with a grin. He was about to reach for his phone to text Annabeth when he heard Will turn to Jason.

"Hey bud, link me Annabeth's digits so I can just message her directly."

Percy's eyes narrowed, "Why do you want Annabeth's number?"

"It'll just make it easier to coordinate for the formal and what color she wants to wear." he shrugged, pulling out his phone.

Percy almost choked on his drink, "Wait, what?"

Jason looked at him oddly, "Yeah... he's taking Annabeth to the formal."

Percy quickly regained his composure, "Oh, is he? I didn't realize they would... be going together." he finished.

Will frowned at him, "Why? What's wrong with that?"

Percy shook his head, "Nothing. Nothing at all." he said between gritted teeth and a forced smile.

They seemed to buy it and Jason gave Will her number as Percy clenched his can of soda unnoticed, and pulled out his phone;

At the lake – 15 minutes. I'm waiting.

ΩΩΩ

Twenty minutes later, Annabeth made her way around the sheet of trees and bushes that covered their private lake clearing to find Percy standing there looking out at the water with his back towards her. It was the perfect place for them to get their alone time near campus.

She grinned and tiptoed closer before giving him a nudge to playfully frighten him. When he turned towards her, he didn't laugh like she expected him to.

"What's wrong?" She asked, as she wrapped her arms around his waist, "Are you mad I didn't leave class when you first texted me? Because, buddy, I was in the middle of my lecture. Even now, I left about ten minutes early."

He didn't wrap his arms around her, and Annabeth frowned at his cold demeanour.

"Percy? What's wrong with you?"

"Are you going to the formal with Will?" he demanded, with a raised eyebrow.

Annabeth scrunched up her forehead momentarily before remembering her conversation with Piper, "Oh yeah. Piper and Jason are going and she insisted that I couldn't miss it," Annabeth answered rolling her eyes, "Supposed to be quite a formal."

Percy pulled away from her arms. "That doesn't answer why you're going with Will?"

Annabeth frowned in confusion, "Because... she said I needed a date as a ticket in the door – which, by the way, I think is a dumb requirement. Anyway, she told me Will would be down to take me and we would all just hang out together. Why?"

"What do you mean why? You're going to a formal with my friend, how's that not messed up?" Percy questioned, visibly angry.

Annabeth raised a brow, "Percy Jackson, are you jealous?"

"No, I think it's messed up." Percy answered quickly.

"Oh my Gods, I can't believe this. You're actually jealous." she teased with a smirk.

"I have nothing to be jealous about. But the girl that I'm hooking up with is going to the formal with my friend, I think that's kind of weird, don't you think?"

Annabeth shook her head, "No, that's not weird at all. I'm going to the formal with Will as my ticket in the door, and secondly, we're hooking up secretly, hence it's not really weird to anyone. You and I both know there is no strings attached here. Obviously we can't go to the formal together-..."

"Oh really? And why is that?"

Annabeth frowned, "I think it's obvious... how would we explain why we'd go to the formal together to Jason and Piper? Plus, I highly doubt Piper would want to spend the formal in your company."

"They're going together anyways."

"That's beside the point, Percy. You can't be mad at me about going to the formal with someone else. That is not included in this thing."

"Oh? Okay, that's fine. I just thought it was a respect thing."

Annabeth felt anger flare up inside her, "Percy, you don't have rights over me, and who I can go to a formal with. This isn't any form of disrespect, you're just mad that your ego is getting bruised by this! And, you know what, I regret leaving my lecture to deal with this." she said, before walking past him to storm off. But he grabbed her forearm to stop her.

"That's fine, Annabeth." he pulled her closer and brought his lips to her ear, "I'll see you at the formal."

She rolled her eyes and pushed away from him and turned o leave. Before his eyes narrowed; don't get mad... get even.

He pulled out his phone and texted Rachel.

Formal?
