The two things that Jake didn't know about Amy Santiago before they started dating?

She was surprisingly kinky, and she hated mornings.

Now the first thing, he found out soon after they got together. He lost count of the number of times she'd pulled him into interrogation rooms and supply closets, pushing him against the wall while she kissed him deeply, and rocked her centre against his leg.

He found out she hated mornings the first time they slept together. She would get up , but she would be bleary-eyed and unaware of anything around her. She was moving on autopilot, putting on clothes she had laid out the night before without checking what she was pulling over her body.

This is how The Idea started forming in Jake's head. He needed to be sure that her attention wasn't on her actions in the mornings, and so switched her bra one morning before her alarm went off.

Amy didn't realise until she sat down at her desk and Gina asked her why she was wearing a black bra under a white shirt.

One Internet order later, and Jake was ready.

One morning, Amy was sat at her desk, sipping a cup of coffee. She'd been working on paperwork for about half an hour when Jake came wandering in, sat down, and shot her a quick wink.

Amy smiled at her boyfriend, and quickly redirected her attention to the arrest file sat in front of her.

Jake sat opposite her, waiting for the perfect moment, a small remote control hidden in his hand. It was a very quiet day, and he was bored, so, about half an hour later, he moved the slider from 0 to 1, held it there for barely two seconds, then slid it back down to zero.

Opposite him, Amy jumped slightly, stood up, and checked under her seat before sitting back down.

"Are you okay, Ames?" Jake asked, feigning concern.

Amy just nodded, brows slightly furrowed in confusion, before returning to her work.

Jake smiled, waited five minutes, then slid the slider up to number 1 again, this time leaving it there for nearly a minute, as he watched Amy shuffle in her seat, then briefly close her eyes, before discreetly rocking forward in her chair.

Amy didn't understand what was happening. She was sat on her chair, like normal, then there was a gentle vibration between her legs. As quickly as it started, it stopped again. She quickly checked her chair, but there was nothing there. Nodding at Jake's query into her wellbeing, Amy sat down. Five minutes later, it started again. And this time, it didn't stop.

The vibration stayed at a steady frequency, and was sat between her legs, in the perfect position to stimulate her clit. She tried to rock in her chair, hoping a little extra stimulation would bring her to a point that she could achieve release. It didn't. And then the vibration stopped.

The rest of Amy's morning followed the same way. The vibrations would suddenly restart, each time bringing her closer to release, and then stop, just as she was about to tumble over the edge.

Eventually, Amy could take no more, and stood up to go to the bathroom, hoping to bring herself some relief.

She closed the door to a cubicle, and pulled down her pants and underwear. Then immediately opened her phone and texted her boyfriend, who she suddenly realised had been looking increasingly mischievous throughout the morning.

Jake grinned as his phone buzzed. Amy had left to go to the bathroom a few minutes earlier, and he knew he was about to be found out.

What the hell?

Jake grinned as he typed out a simple reply. He wasn't about to show his hand just yet.

?

You know what I mean Peralta.

Sorry Santiago, you might have to give me a hint.

How's this for a hint? These aren't my panties.

No?

No, and they're vibrating.

Oh yes, I thought we could have a little fun. You up for it?

What if I'm not?

Well, you could go commando, but I have this strange feeling that you're kind of wet. Do you want to risk it?

Amy sighed at the last text. She was indeed very wet between her legs, and knew there was a very good chance of it leaking through her trousers. Sighing, she went to slip her hand between her legs, to give herself a quick release, before another text came through.

No touching yourself. My game, my rules. I will know.

Amy rolled her eyes, suddenly feeling defiant. How would he know? Smiling, she put her hand back between her legs, rubbing small circles over her clit with her thumb, one finger pushing inside her.

Throwing her head back and suppressing a groan, she felt her walls clamp around her finger as her orgasm hit her.

She gave herself a few seconds to recover, then pulled her trousers and those panties back up, before washing her hands and heading back out to the bullpen.

Jake smirked as she headed back to her seat. She was avoiding his gaze, and he could smell the soap coming off her hands. Yep, she had definitely just masturbated in the bathroom after he had told her not to. Grabbing the remote control, he slid the slider up to number 2, waited for her head to whip up in surprise, then slid it back down to number 1, and left it there while he picked up his phone once more.

Amy was still sensitive from her previous orgasm when she felt the vibrations stronger than before. She lifted her head up, her eyes connecting with Jake's in shock. The vibrations eased slightly, and her phone buzzed beside her.

Tut Tut Detective Santiago. Disobeying a direct order? Such insolence has to be punished, don't you think?

Amy froze. How did he know? She was in trouble now. He held all the cards. Just as she put the phone down, her office phone rang. As she picked it up to answer, the vibration between her legs suddenly escalated again. Unbeknown to her, Jake had bypassed level 3 and went straight to 4.

Jake grinned as he watched her try and end the phone conversation quickly. She hung up the phone, gripped the edge of her desk and began to pant. Quickly, Jake turned the vibration off, Amy falling back in her chair, wriggling slightly at the sensations coursing through her body.

Amy was in hell. All morning she had been on the edge of the most intense orgasm of her life, and yet Jake wouldn't let her go over the edge. She didn't dare to do it herself after earlier. But that didn't mean she couldn't get her own back a bit.

She took her opportunity when she got back from lunch and the bullpen was completely deserted. Terry was out with his daughters, Boyle and Gina were at some weird family dinner, Rosa had the week off, and Hitchcock and Scully had gone looking for Brooklyn's best sub.

An idea quickly formed in her mind, and she ducked under her desk, pulled her chair in, and waited.

Twenty minutes later, she heard Jake come back and sit down. Just as she was about to put her plan into action, she heard footsteps approach their desk. She momentarily paused as she heard Captain Holt engage Jake in conversation, but decided this was too good an opportunity to miss.

Jake was talking to Holt when he felt it. Somebody was under his desk, and as quick as a flash they had undone his pants and taken his cock in their mouth. Startled, he put a hand under his desk, relaxing slightly when he felt Amy's long hair weave through his fingers.

He could feel himself getting closer to an orgasm, and could barely hide his relief when Holt finally went back to his office. Immediately, he put his hand back to Amy's head, thrusting slightly into her hot, warm, mouth. But just as he felt himself tensing up, Amy pulled back and reappeared in her chair. Groaning, Jake took a few seconds to compose himself when he heard his phone vibrate.

My game, my rules.

Jake just chuckled, looked up at Amy, and held her gaze as he lifted up the remote control to where she could see it, moving the slider up to the top. Level 5.

Amy immediately jumped in her seat, stood up, and growled at Jake,

"With me. NOW."

Jake, grinning widely, wasted no time in getting up to follow her.

Slamming the door to the storage cupboard, Jake pushed Amy against the door, pulling her trousers and underwear off before pushing his down to his knees. He lifted her up and thrust quickly into her, both of them letting out a groan as Amy wrapped her legs around his waist.

Jake thrust in and out of her fast and hard, groaning as he grew harder, spurred on by the sighs and moans coming out of Amy's mouth, and the way she gripped hold of his shoulders through his shirt.

After their antics that morning, neither of them could last long, and before long Jake captured Amy's mouth in a passionate kiss to muffle their screams as their orgasms washed over them.

Jake slowly moved to slip out of Amy, but stopped when Amy tightened the hold that her legs had on him. Looking at her, he grinned at her next question.

"You've been playing all day. Do you really think you can get away with only making me cum once?"

Jake grinned.

"Believe me, babe, I would love to, but it'll take me a few minutes. We're nearly at the end of shift. How about we go back to mine and continue there?"

That obviously wasn't good enough for Amy, who put her legs down so she was standing again, and as Jake's cock slid out of her, she pushed Jake to his knees.

"Trust me, we will, but I need to cum again now. And if you can't use your cock, you'll have to use your mouth."

Jake just nodded and leant forward. He buried his face in her pussy, taking long licks, drifting up to flick his tongue over her clit every so often. Amy pressed herself onto him harder, gripping his hair.

Jake pushed two fingers inside her and sucked her clit between his teeth. She cried out as he pressed three, then four fingers inside her. He smiled as she shouted out, walls clamping down on his fingers, and her legs buckled completely under her, so she was sat on Jake's face completely. She whimpered as Jake continued sucking on her clit, fingers still inside her, coaxing out one orgasm after another until she eventually begged him to stop, shivering as he removed his fingers from her still clenching pussy. Giving her a minute to regain her composure, they both redressed and hurried out to Jake's car.

Three hours later...

Amy screamed as she held on to the headboard behind her. She was laid on her back, her legs were over Jake's shoulders, and he was kneeling as he pounded into her with an energy that didn't suggest they'd been going non stop from the minute they got to his apartment. Jake had slammed the door, and wasted no time in bending Amy over the back of the sofa, fucking her hard enough that the piece of furniture had moved forward and hit the coffee table.

Amy mewled softly as she came again, and Jake followed not far behind. Falling to the side of her, the both panted, trying to catch their breaths.

"Hey, Peralta?"

"Yeah, Ames?"

"If Holt asks me why I didn't get any work done today, I am blaming you entirely."
