A/N: First of all, thank you all so much! The response to this story has been amazing so far and it's only just beginning. At this point, I have 6 total chapters planned out which should be posted regularly, especially with the response that you've had so far. All those notifications really do get my imagination going and my fingers writing faster and I'll be off to work on chapter 3 as soon as I finish here. And so without further ado, here's the second chapter.
And a note to add that hasn't been cooperating with me these last couple days and isn't updating properly when I post new chapters so if you get a double notification about this chapter, my apologies.
Castle was much less careful about his personal activities after that afternoon. He always ensured that he was in private any time his mother or daughter was home, but Beckett? Well, he wasn't going to be upset if she happened to see him otherwise occupied.
He didn't get a chance to test his theory for another week. A new case had come and gone and he'd spent the last several days at home, catching up on his writing while Beckett and the team filed all of the necessary paperwork to close the case.
Alexis was in school and his mother was off doing things he didn't really want to consider and wouldn't be back for a while. Knowing Beckett as he did, he suspected she'd send the boys home to start the weekend early and come back to the loft for a late lunch as long as a new case hadn't broken.
He didn't want to be too obvious and so he remained in his office, seated once more in his desk chair when he opened his laptop and pulled up a new incognito tab. This time he set the computer at an angle so that the screen was facing his office door. Even though he didn't know that Beckett had seen him before, his overwhelming curiosity demanded he test her reaction to seeing him jerking it to porn in his office. After all, he knew she was thinking about him when she did the same.
This time his search was more dutiful. He spent more time than usual searching for just the right video to watch. This time he was looking for a beautiful brunette. This time he wasn't going to try to get off without imagining his partner. Hell, what he'd seen the week before gave his imagination enough material to work with for a month. But using purely his imagination didn't fit in with his plan, so when Castle had found the perfect video, he clicked play.
It was a long one even if pretty straight forward as far as porn went and he was ready before he'd even unzipped his jeans. The writer hoped he'd be able to last long enough. He didn't know when exactly Kate would return to the loft, or if she even would. He thought he knew her well, but was still operating on a large amount of guesswork. This could all blow up in his face if he had guessed wrong.
Castle took hold of his manhood and with a couple of quick, practiced strokes he had brought it to full attention as his gaze was drawn to the couple on screen. The woman was giving the man a blow job and he couldn't have stopped himself from imagining his partner on her knees, mouth wrapped around his cock if he had tried.
He nearly startled when he saw movement out of the corner of his eye. Beckett was there. Standing just to the side of his office doorway. Her wide eyes were honed in on his engorged member in his hand and she hadn't noticed that he had seen her.
He watched her with his peripheral vision, noticing the way her jaw dropped when the camera on screen panned back to show the couple. She hadn't missed how that the onscreen actress bared an uncanny resemblance to herself.
For a long moment she couldn't tear her gaze away from the screen of his laptop. The image before her was one that would forever be seared into her memory. That of Castle watching a hard cock thrusting into the body of a woman who looked remarkably like herself. So much so that they could be confused for one another from a distance.
There's no way that was an accident. He had to have noticed the similarities when he chose that specific video. The woman on screen had her same sun kissed brunette hair cut to shoulder length. The same long legs and fit, womanly body completed the picture. He may as well be jerking off to a picture of her and the thought did strange things to her body.
Her knees go weak when she hears him groan out her name, but he doesn't turn towards her to indicate that he knows she's there. Doesn't try to hide himself or what he's been doing. Instead, the steady motion of his hand speeds up and he remains engrossed by the video playing before him.
Beckett licks her lips, her gaze now drawn to the evidence of his arousal. The evidence of how much he wants her. She can just see glimpses of the veined shaft and rounded head of his manhood. She wants to see more and nearly steps forward into the room before stopping herself. Instead, she steps backwards. And again, she walks away from the tantalizing picture presented by her partner without ever removing her eyes from him.
He curses and she can't help but pause at the bottom of the stairs to watch his release. The way semen spurts from his cock in thick ropes that she desperately wants to catch on her tongue. Instead she finally turns towards the stairs and mounts them two at a time. Rushing for the sanctity of her room where she can shuck her slacks and panties and collapse heavily onto the comforter.
Within moments she has her fingers stroking through her folds. The evidence of her arousal at seeing her partner cumming before her coating her seeking digits.
She doesn't realize, in her haste, that she hasn't closed the door completely. Neither does she hear the slight creak of the stairs as the man of her envisioning trails in her footsteps.
Closing her eyes, she replays the image of Castle pumping his hard, thick member to her look-alike in her mind as she thrusts two fingers into her slick opening. Head thrashing, she brushes her thumb over her clit as she moves her fingers in and out, crooking them against her front wall and that spot that drives her crazy.
Head to the side, she opens her eyes, intent on finding the vibrator she's placed in her bedside drawer when she makes contact with another pair of eyes. These the color of the ocean and just as deep. Castle is watching her.
He'd seen the way she had watched him. Unable to tear her eyes away even as she had backed across the loft and that knowledge was all it took to push him over the edge. When he'd come down from his high she was gone and he had a pretty good idea what she'd be doing.
Unable to control himself, Castle traced her footsteps up the stairs to the guest bedroom, her bedroom, once more. He came up short when he realized she hadn't shut the door this time, and that she wasn't in the shower. Instead, she was laying on the bed. Fingers buried in her wet pussy, she was bare from the waist down.
Despite her wide spread legs, he couldn't see where her fingers disappeared into her body but he could see her mile long legs in all their glory and the opposing rises of her pubic mound and her supply ass. He nearly choked on his own tongue when he realized that she was clean shaven.
She shook her head from side to side, building herself up, and when she opened her eyes and looked directly at him he couldn't make himself pull away. Her dark eyes were unreadable as they made contact with his own and he froze, waiting to see what she would do.
The moan that erupted from somewhere deep in her chest seemed to startle them both and she resumed fingering herself. He hadn't even realized that she'd paused her ministrations for a quick second.
The two maintained eye contact as Beckett continued to work her body higher. All thoughts of turning away to find her vibrator forgotten. Castle had to have seen her earlier, she realized and instead of fear churning in the pit of her stomach, she found nothing but heightened arousal.
Shelving the questions that realization brought up for the time being, she pressed her thumb harder against her clit and a whimper escaped her lips. She was so very close.
The moment she broke eye contact with Castle- when he licked his lips as he watched her writhing, half naked form was the moment she lost all control. Her body twitched and jerked as her orgasm washed over her and her eyes slammed shut against the overwhelming sensation.
By the time she came down from the amazing high she had achieved and was able to open her eyes despite the aftershocks still trembling through her body, he was gone. She almost would have believed that he was never there in the first place if it hadn't been for the immense power of her release. He had watched her drive herself to the edge and then over with the taste of his name on her tongue and instead of the dark edge of despair she might have expected, she felt only a heady, unprecedented lightness. That, and the desire to do it again.
