These are incredibly fun to write so here's another one.

Thanks for the reviews/favourites/follows for the previous chapter, the fact that you guys want more keeps me writing.

Disclaimer: I don't own Castle or the characters.

They'd managed two days, two days where no one else had found out about them. Castle thought his family may suspect something since he hadn't slept at home in the past two days, but they hadn't said anything. He was going to bring it up with them, just not quite yet, he was enjoying having Beckett all to himself.

They had picked up a case and now they were at a crime scene, having come straight from Beckett's bed. Lanie was giving them knowing looks which they both chose to ignore and just hoped the boys didn't notice. Beckett was going to have to have a word to Lanie about that later though.

Yesterday all Beckett had done was paperwork and Castle had had meetings to go to for his next book so they hadn't seen each other at the precinct. This was good because it meant less chance of someone finding out about them but they'd missed each other so much they hadn't even made it to Beckett's bedroom the previous night when he'd turned up at her place. Well they did make it to her bedroom, but only for round two.

So now they were at the precinct together for the first time since things had changed between them and they were both finding it difficult to keep their distance from each other.

Neither was making it easier for the other though as any chance they got, they'd make physical contact of some kind. It ranged from a simple brush of hands when Castle handed Beckett her coffee to more risky behaviour like Beckett sliding her hand up Castle's thigh under the table. All this teasing contact only left them wanting more.

They were both to blame for what happened next after how they'd been touching each other all day. Castle had suggested it but Beckett had been all too keen to go along with Castle's plan. She was to leave her desk, file in hand, as if she was actually working and then several minutes later, Castle was to follow and they were going to meet in one of the mostly unused corridors in the back of the precinct.

That part of the plan went off without a hitch and before Beckett knew it, Castle had her pushed up against the wall in much the same position as she'd been when they were caught their first night together. Relief flooded through her as Castle's body came into contact with hers. She moaned out loud but she didn't care, they were alone and she didn't care if he knew how much she wanted him.

They don't know exactly how long they'd been there, doing what they'd both been thinking about doing all day, when they heard a loud gasp behind them. They jumped and looked towards the sound of the noise to find a very startled and red faced Ryan.

Beckett was suddenly extremely glad they both had all their clothes on although that didn't stop Beckett from being rather embarrassed at what Ryan had just witnessed. It'd just been quite a heated make out session but that was all, they were at work after all.

"Ryan!" Beckett exclaimed, sounding rather breathless so she pushed Castle back, who was still mostly pressed up against her, so she at least could get her breathing under control.

Ryan just stood fixed on the spot, a look of shock and horror etched across his still very red face.

"You okay there Ryan?" Castle asked, laughing slightly when Ryan had still said nothing and was trying not to look them in the eye. While Castle was embarrassed about how they'd just been caught, the look on Ryan's face was rather amusing. Plus, Beckett wasn't freaking out so he didn't need to either but he thought he should at least say something to break the silence.

"I...yeah," Ryan said, voice strained as he was still trying to process what he'd just seen. He'd always thought that there partnership was leading to this kind of relationship. He just thought that when that did happen, he wouldn't find out by catching them making out in a dark corridor at work that he can't even remember why he's in now.

He turns to make a quick exit, barely having said two words but Beckett's voice from over his shoulder stops him, "Ryan, wait."

Ryan turns, blushing again as he sees that while Castle has now stepped even further away from Beckett, they have their hands intertwined.

"You won't tell anyone about this, will you?" Beckett asked, nodding her head to their joined hands, "It's just Gates-"

Ryan interrupts her, knows what Gates would do to their partnership if she found out. It was their business anyway, whether they wanted to tell people or not."Of course not."

"Thanks," Beckett replied, smiling at Ryan who nodded his head in return, only making eye contact for a second before he looked away embarrassed again.

Ryan cleared his throat, "I..ahh…better go." Whatever reason he'd been in this part of the building can't have been that important anyway.

As soon as Ryan had left, Beckett turned to Castle, burying her head in his chest as his arms came up around her to hold her close as she spoke, "well that was thoroughly embarrassing."

Castle just laughed in response, the sound vibrating through Beckett.

"Do you think we scarred him for life?" Beckett asked, the words said into Castle's chest.

Castle laughed again, "I don't think so, but I'm sure he'll have a hard time looking us in the eye for a while."

Beckett extracted herself from Castle's arms, giving him a quick kiss before speaking, "We better get back ourselves, before someone notices we're missing."

"We can continue this tonight?" he asked, stroking his thumb over her cheek.

"Of course."

"At my place?" Beckett heard the uncertainty in his voice but she wasn't sure if it was because he was unsure about inviting her to his place or whether he was unsure about what her answer would be.

"Are you sure?"

Castle kissed her this time, lingering as he pulled away. He knew from the way she asked that she wanted to come over to his place just as much as he wanted her there and that erased any uncertainty from his mind as to what her answer would be.

"Of course I'm sure," he replied, smiling softly.

"Then your place it is," she said, smiling in return and suddenly nervous about this evening. She knew that tonight he was going to tell his mother and daughter about their new relationship and while in the past that would have made her turn and run, now she was excited about this next step in their relationship.

When they returned to the bullpen, they could hear Esposito asking Ryan what was wrong since he was still rather red. He told Espo he was fine but as he said it, he looked up and caught sight of them walking back to Beckett's desk. Ryan blushed again and quickly looked away. Luckily Esposito didn't seem to notice because he let the subject drop.

Beckett had to put her hand over her mouth to stop herself from laughing because he really did look

traumatised. Beckett was just glad that was all he had walked in on otherwise he really would have been scarred for life.
