Amy Santiago had never, ever suffered from any kind of hangover in her life.

She'd been drunk a fair amount of times, but had always gone to lengths to ensure that she felt completely normal when waking up the next day. Drinking a few glasses of water, taking some pain meds, the usual.

So when she woke up this morning with a monstrous headache and a nauseating sensation in her stomach, it was expected that she was confused and worried.

Once her eyes had gotten used to the early morning pouring through her bedroom window, Amy frowned and lifted her head from the pillows. The first thing she noticed was the smell of men's cologne. What on earth had she done last night?

Twisting herself out of the covers, she sat up and rubs her eyes. She hadn't removed her make-up last night. Very unlike her.

Pushing her hair back, she browsed over her bed, especially at the space next to her (just in case another body was sleeping there) until her eyes fell on a leather jacket. Straight away she knew who the leather jacket belonged to. It was like his signature accessory.

Santiago's heart dropped as she imagined all of the possibilities that could have taken place last night, only just noticing the clutter escalating from her kitchen. He was still here. She sank back into her bed with wide eyes, begging and pleading to absolutely no one that nothing had happened. The last thing she remembered about last was going to the bathroom at the bar, thinking to herself that she was very very drunk. All the rest was a blur.

After ten minutes of thinking about worse case scenarios, she decided to tiptoe into her bathroom linking to her room and had a cold shower to wake her mind and her body up. She felt better once washing her hair and cleansing her face. Placing on a fresh pair of shorts and a baggy t-shirt, she decided that it was time to face him.

Her heart racing, she shuffled out of her room and into the living room and kitchen. Her eyes wandered to the back of Peralta as he rummaged around the kitchen, preparing what looked like breakfast while humming a tune. He seemed at ease.

Being the chicken she was, Amy cleared her throat quietly to gain his attention. His head spun around before he grinned.

"Morning, sleepyhead."

Amy couldn't say a thing.

"Hey, I hope you didn't mind, I used your shower, and I kind of cleared out your cupboard and fridge to make some breakfast." He turned to face her and leaned back on the kitchen side. "You need to go shopping, by the way."

He seemed, happy. Normal. Too normal. As if nothing had happened. How could he be so normal?!

"Jake..." Amy began, folding her arms. "Wh-what exactly happened last night?"

"Oh my gosh, you were acting so crazy last night. The opposite of what you usually act like. You were like an animal." Jake grinned with a chuckle.

Amy felt her stomach churn. An animal. They had wild drunken animal sex and she couldn't remember a thing.

"Oh god."

"Yeah, you couldn't keep your hands off of me."

"Oh, no." Amy placed her hands on her stomach. "No, no, no, Jake."

Jake frowned while watching Amy double over, her towel dried hair dangling over her head.

"I can't believe this."

"Can't believe what?" Jake questioned as she stood up straight with worry and regret plastered all over her face.

"It wasn't suppose to happen this way, not like this!" Amy exclaimed.

"What are you talking about, Santiago?"

"You and me, it..." Amy was lost for words. She was stunned.

"Sorry, what?" Jake's head leaned forward as he took in what his partner said.

"It wasn't meant to be like this. It wasn't supposed to be drunken and messy." Amy brought her hands to her face.

Jake's eyes widened as he realized what she was saying. A small smile crept upon his lips.

"Amy, we didn't have sex."

Santiago halted and her stomach dropped. They didn't have sex. Bringing her hands away from her face, she stared at Jake with embarrassment.

"What?" Her voice sounded so small, practically a whisper.

"Me and you? Yeah, we didn't do it."

Amy blinked. "Wh-"

"You were drugged by some weird guy at the bar, he'd put something in your drink. So the team arrested him while I drove you to the hospital, you blacked out in my car, woke up at the hospital, went all excited and giddy on me, I brought you back home and you turned into this weird sex-craved monster with your hands all over me begging for it, and then I eventually got you changed and into bed. I slept on the couch, don't worry."

Amy was horrified. "Oh my god."

"Yeah, it was pretty crazy."

"Did I...change in front of you?" Amy mumbled.

"Oh, yeah. I saw everything. Lucky you had underwear on, huh, Santiago." Jake smirked.

"Oh, god!" Amy covered her face again. "I can't believe this."

"How about we go back to what you said a few minutes ago?" Jake asked with a sly grin.

Amy peeked at him through her fingers.

"So, you and me. What was it suppose to be like, Amy?"

Amy felt her face turn a bright shade of red. She actually said that. How was she suppose to recover from that? She'd basically admitted that she liked him. Or wanted to have sex with him. Either way, it was bad, and she knew Peralta would never let her live this down.

"Amy." His voice was calm and collected.

Santiago let her hands drop and she sighed. "Fine. Fine! I like you. I think. I don't know!"

Jake pulled in his lips to try and stifle a smile as he felt his heartbeat increase with happiness.

"But at the same time, I can't stand you, because you're a man child, and you're annoying and un-organized and you're always picking on me-"

"Picking on you?" Jake lifted an eyebrow as he listened to her rant, a playful look in his eye.

"Yes! Always making fun of me."

"Well, that's because you're so easy to make fun of." Jake grinned.

Amy felt the anger rise inside of her. "See, that's exactly why this wouldn't work! You're so childish and pathetic and I just wish-"

She couldn't finish her sentence, because Jake had taken a couple of steps forward with his stupid grin still visible and he cupped her face with his hands and he kissed her.

He kissed her, with all of his might because that was all he'd been wanting to do ever since he'd met her. To kiss her and hold her and laugh with her and argue with her and make love to her and hold hands with her and to just be with her. All the time. Him and her, that's all he wanted.

Amy breathed in with shock, her eyes wide as Jake pulled away.

"Well, that shut you up, didn't it."

Santiago gripped onto Jake's t-shirt and pulled him back, locking her lips with his. Their lips parted, allowing access for their tongues to explore. Jake could taste the mint of Santiago's toothpaste.

Jake's hands slid down Amy's waste before settling on her hips, pushing her against the wall.

Her fingers tangled in his messy bed hair as he lifted her from the ground, wrapping her legs around his waste. They broke the kiss and looked into each other's eyes.

They both were happy, excited, scared. This would change everything. They'd be breaking so many rules in the precinct.

Continuing their kiss, Jake carried Amy into her bedroom and they flopped onto the unmade bed.

Peralta never played by the rules, anyway.
