Beckett's Sister: A Castle AU Fanfiction

Chapter 13

Castle was sitting on the couch with a bowl of popcorn as he grabbed the TV remote and brought up the DVR list. He hit play for the most recent episode of Game of Thrones and settled in while Kate was in the shower. When she emerged twenty minutes later, he was so engrossed in the episode that he didn't even hear her enter the living room.

Kate made her way over to the couch and sat down beside Castle, grabbing a handful of popcorn as she watched him, lost in the TV. After looking at her phone for several minutes, she put it down on the coffee table and turned to face Castle. Smirking to herself as she popped the last few kernels in her mouth, she wiped her hands off on her pants and leaned in next to him.

"Castle." Kate slowly whispered in his ear, grinning when he didn't even flinch in response.

She sat up on her knees, putting one hand on his thigh and the other on his shoulder. She nuzzled his ear with her nose, hearing the slight hitch in his breathing and played with the short hair at the nape of his neck.

"Castle." She whispered again, placing light kisses along the side of his neck. She grinned when he moved his neck slightly to give her better access but he still had not taken his eyes off the TV screen.

She began running her fingertips along the top of his thigh and lightly kissed him on the cheek. He was fighting to keep his eyes on the screen, torn between watching the end of the episode or getting touchy feely with his fiance. Eventually touchy feely won out, remembering the last time he ignored her for entertainment purposes. He fumbled for the remote as Kate continued kissing his neck, turning the TV off and grabbing her by the hips, pulling her over to straddle him.

"You, my beautiful fiance, are evil." Castle said, running his left hand through Kate's hair, tracing her bottom lip with his right thumb then running his hands down her sides to settle on her hips.

Kate closed her eyes as she took in the feel of his strong hands on her. She smiled as she replied "Well, I had to get your attention somehow."

Kate opened her eyes, looking down into his blue ones that she loved so much as she leaned down to capture his lips with hers. She let out a small moan, which Castle captured as he slid his tongue into her mouth. The kiss deepened as Castle snaked his hands underneath her shirt, rubbing circles along the now exposed skin of her back. Kate grinned into the kiss as she felt him inch his hands further up her back.

"Something I can help you with, Mr. Castle?" Kate asked as she broke the kiss, running her hands over his broad chest.

Castle let out a hiss as Kate inched the front of his shirt up and ran her hands over his stomach. "So much, Kate, so much." He said as he claimed her lips again.

His hands found the top of Kate's yoga pants just as her phone began going off. Dropping his head to her stomach, Kate let out a laugh as she reached for the offending device.

They weren't on call but she checked to make sure there was not some sort of catastrophic emergency that would require their assistance. As she glanced at the caller ID and saw who was calling, she huffed out a laugh and threw the phone back down on the coffee table.

"Who is it?" Castle asked, craning his neck like a giraffe trying to see her phone screen.

"Little sister. She can talk to my voice-mail." Kate said, grabbing the hem of Castle's shirt and pulling it over his head.

"Like I said, pure evil." Castle said, following suit with Kate's own shirt and throwing it behind him over the couch.

"If I'm so evil, Castle, why don't you punish me?" Kate bit her lip as Castle put his hands under her thighs and stood up, carrying her into their bedroom.
