A/N: This actually isn't the second chapter featuring the white shirt I originally thought of…

She trapped the phone between her shoulder and ear, using her hands instead to stir the pasta sauce around the saucepan and stop it from sticking to the sides.

After a moment of listening just to the dial tone, Rick picked up, not even bothering with giving his name.

"I made too much pasta. You wanna come over for dinner?"

"Is this a habit of yours?" he mused, unable to stop grinning however, simply because of the thought that Kate cooked too much food as an excuse to see him. "Double Chinese order, can't finish a pizza, mixed-up grocery delivery…" He rattled off a list, remembering all the times he had been able to have dinner with Beckett while they were still just friends, times when she curiously always had an excess of food.

"Is that a no?" she countered rather than answer.

"Give me ten minutes," he requested, already standing up and saving his work on the latest Derrick Storm book. As soon as he hung up, he shuffled into the bedroom to put some real clothes. Although he didn't think Kate would mind him only wearing a pair of boxers and his Green Lantern shirt, he didn't think it would go down so well with the rest of the tenants in her building. Once he was wearing pants and had his wallet in his pocket, he was on his way, only stopping to grab his keys. With Alexis spending the month with her mother in California, it was much easier for him and Kate to meet up with no questions asked, though more often than not they would stay safe and only spend time at her apartment just in case his mother happened to waltz in on them.

After jogging up the stairs inside her building he knocked, assuming a casual position against her doorframe as he waited, crooking one leg in front of the other and crossing his arms over his chest.

"You rang?" he asked as the door swung open and revealed her standing in his shirt, the one he had gifted her just over a week ago, with the sleeves rolled up to her elbows. It was the third time she had worn the shirt and every time he had barely been able to restrain himself from ripping it apart. He stifled a groan and made sure to keep his eyes from trailing down to stare at her bare legs. He could swear she chose to wear his shirt on purpose, knowing what it did to him.

If anything, she only confirmed his theory when she hauled him into her apartment by a fist curled around the material of his t-shirt before thrusting him back against her front door, on him in seconds and attacking his lips with a passion.

"What about dinner?" he murmured, only getting a disgruntled noise out of her and an impatiently growled reply.

"Later."

Spinning, Rick lifted Kate, securing her legs around his hips and holding her against the door instead, hands under her thighs and inching towards her derrière only to discover quite delightedly that she had forgone underwear. Oddly enough though, the shirt stayed on the entire time, clinging to her sweaty skin even though Rick had persevered with his clumsy fingers to get each button through its respective hole. It stayed on her body as he carried her away from the door, stumbling into her bedroom as she did that thing where she curled her tongue around his and simultaneously tugged on the ends of his hair while kneading the muscles of his neck with the base of her palm.

She was still wearing it as she collapsed down onto his chest, muscles losing their ability to keep her upright. It was buttoned up again though when she finally rose, no longer boneless, and trotted out to the kitchen to relight the stove and heat up their dinner. He watched her flit around between the cupboards, re-rolling the sleeves of the shirt up past her elbows to stop them from falling past her hands, finding seasonings and adding them before grabbing plates from one of the higher shelves; getting a teasing flash of the tops of her thighs that made him want to grab her by the hips and hustle her right back to the bedroom.

At the rumble of his stomach however, he sat down in his boxers and took the opportunity to stroke his hand across her back as she approached with plates and pasta bowls, setting one in front of him and the other at the place to his left.

"You don't need to use dinner as an excuse to see me, you know," he said as she took the saucepan of pasta off the stove. "If you want a booty call, I'm more than happy to oblige." He waggled his eyebrows, smirking because he knew exactly what kind of effect he had on Kate Beckett now.

She paused, leaving the pan on the side and instead coming to sit, surprising him as she plonked herself down into his lap. Her arms fell around his shoulders.

She blushed as she admitted, "So I was a bit horny." He grinned with satisfaction, wincing though as she tweaked his ear only to retaliate by shifting her on his lap so he could squeeze her butt. "I thought the…desire would fade a little," she explained after a moment, her features gentling into a reflective gaze and a small smile. All the other relationships she'd been in had never been so intense. Sure the first week or so had been a bit of a whirlwind when she was younger, more naïve and more easily infatuated with a guy, but afterwards it had never taken long for things to settle down into a boring kind of routine. It was even more surprising to her that that hadn't happened with Castle since they had already known each other so long and well.

He knew exactly what she meant. After so many years only able to fantasise and dream about what it would be like to finally have sex with Katherine Beckett, he hadn't been surprised by how earth-shatteringly profound their first time had been and how many rounds they had subsequently had. He did think that in the weeks since though they would have been more sated, more able to take things slowly and really appreciate one another.

"Nothing wrong with a little passion, Beckett," he pointed out, kissing her again and squeezing her side before releasing her so that they might finally eat their dinner. Afterwards there would be time to fall into bed together again, or maybe stop at the couch if the bedroom was too far away. It wouldn't be the first time such things had happened.

She smiled, grabbing the pan again and finally bringing it over to the table to serve Rick with some carbonara. She spooned some into her own pasta bowl and returned the saucepan to the stove before sliding into the seat beside Rick, leaning in towards him so their arms touched, the hairs on her forearms prickling upright at the contact with his warm skin.

Shovelling forkfuls of pasta into his mouth, Rick ran his fingers along her arm as he chewed each mouthful. As goosebumps appeared over every inch of her right arm, he smiled, making his touch even lighter and sending a wave of lust through Kate's body that had her flicking her hooded gaze over him.

One thing was for sure. Beckett's suspension was going to be an action-filled few weeks.

A/N: I hope you guys enjoyed this. Because I had another idea I was originally going to write, there's going to be another one coming soon though for variation it might be a in a couple of chapters time. Thank you so much for reading, and even more to those of you who have taken the time to let me know what you think.
