Chapter Text
Kate Beckett realized that one of the great things about being Rick Castle’s girlfriend was his ability to just buy airplane tickets for a trip to Las Vegas because they had a free weekend. First class tickets too. She was enjoying the glass of champagne the pretty blonde flight attendant, Jacinda, had handed her while Rick was being his usual charming self. Jacinda left to go help another person and Rick turned to her with a grin.
“Want to join the Mile High Club, Beckett?”
“What makes you think I haven’t already joined, Castle?” She laughed at the expression on his face – something halfway between hurt and turned on. She grinned at him, and said, “I haven’t already joined, but I think I’d like to!” With that, she put her hand on the bulge in his jeans. She rubbed it and then squeezed it. He tried to hold in the yelp, but he couldn’t. The blonde flight attendant must have realized what was going on, and she walked over with a blanket and a towel in her hands. She passed it to Rick with a smirk.
Kate took the blanket and spread it across their laps, kept the towel nearby and got back to rubbing his cock through his jeans. For a change, Rick wasn’t saying anything; he was just sitting back and letting her do what she wanted. So she decided to go a little further and unbuttoned his jeans while rubbing his cock. Then she lowered the zipper very quickly. She reached into his boxers and took his cock out. She could picture it in her mind as she stroked it. She’d had his cock in her mouth or in her hands many times now. She just stroked it over and over again.
She was so focused on what she was doing to him, she was surprised when she felt his finger in her pussy. She had worn a skirt today – it was for him since she knew he loved to look at her legs – and right now, she was fucking glad she did. She had to bite her lip to keep from moaning. He kept moving the finger around and then he put another one inside. Her hips bucked off the seat but his arm kept her from falling. Kate realized she had stopped stroking him so she went back to it.
Soon, they were oblivious to anything else; they were just enjoying this little interlude. Both of them were trying not to moan or groan, and so far, had not. Kate knew one way for her to be making less noise – she could put his cock in her mouth. So she leaned over his lap, lifted the blanket and did it.
Now it was his turn to jump, and in his shock, he removed his fingers from her pussy. Kate didn’t mind since she had a mouthful of cock and she was enjoying that treat. She had sucked in all the way in and had the head down her throat.
Castle got over his shock quickly and had her clit between two fingers. He knew he was seconds away from shooting his come down her throat, so he was hoping to time her orgasm just at the right moment. As he felt his balls start to get ready, he pinched her clit.
Kate could tell that Castle was about to come and then she felt his fingers work their magic on her clit. She came as he started to come too. When he finished coming, she let his cock slide out of her mouth, and he took his hand off her clit and out of her pussy. She removed the blanket off their bodies, sat up and watched as he licked off his fingers. And then she made sure he watched as she licked her lips and grinned at him. She was handing him the towel when the blonde flight attendant appeared next to their seats.
“Care for a drink, Mr. Castle, Ms. Beckett?” she smiled at them. Kate had a feeling she knew what they had just done, but she didn’t care. Rick asked for waters for both of them and Kate got up to use the bathroom. The water was waiting for her when she returned to her seat and she gulped down half of it while Castle laughed at her. She punched him in the arm, but grinned at him anyway. She was tired after everything, so she leaned on him and fell asleep.
Some hours later, he shook her awake and told her they would be landing soon. She thought he looked like he had a secret, but she was going to let him tell her. At this moment, all she wanted was a meal and a great big class of wine, and then she wanted to take him to bed. After they landed, they both gathered up all their stuff and started to walk off the plane. Jacinda smiled at them as they left. Castle took her hand in both of his and leaned over to whisper in her ear. What the hell is he doing? She figured it was something to do with his little secret, so she decided to forget about it. After grabbing their suitcases from baggage claim, they went off to wait for the limo to drive them to the hotel.
As soon as they were in the back seat of the limo, Beckett turned to Castle and said, “I know you’re up to something, Castle. Tell me now so I don’t have to hurt you.” She went to grab his ear, but he moved his head out of the way. She glared at him, which just made him grin. But he knew she could take him out in an instant, so he started to talk.
“Remember when we had that night with Hunt? And I asked you if you would like to watch me with another woman? Remember that you said ‘not tonight’? Well, I talked to Jacinda, you know, the flight attendant?” Beckett nodded at him to continue. She had a feeling where this was going, and she liked it. So did her pussy, if the tingling meant anything. But she’d let him go on. “Well, I thought she’d make an interesting third party – you could watch us have sex. What do you think?”
Beckett knew she could tease him, but why waste the time? This was a great idea, and maybe he’d get to watch her have sex with Jacinda too. When she had that thought, her body responded and she could feel how wet her pussy was. “So I get to watch you have sex with her?” He nodded very enthusiastically, and she almost burst out laughing. But somehow she managed to keep her straight face. “I do have a question,” she said. He looked her in the eye and nodded and she continued, “Would you like to watch me have sex with her?” and then she finally gave into the laughter.
He threw himself at her and covered her face in kisses. “Fuck, Kate, you are the world’s best girlfriend!” He went on to say how Jacinda would join them tomorrow. Apparently, she was based here in Vegas, and she had a few days off.
Kate started kissing him back, and they were about to start something when she realized they had arrived at the hotel. She broke off the kiss, and laughed at his upset face. “Romeo, we’re here. You’ll just have to wait for your reward.” Now she laughed at how eager he was to get inside. And before she knew it, they were whisked up to the Penthouse Suite and Castle had tipped the guy who handled their luggage. She was looking out the windows when she heard the door close, and she turned around to see Castle walking over to the champagne bottle. He had the bottle opened and had poured them each a glass as she walked over to him. He handed her a glass, they clinked glasses, and she toasted him.
“Thank you for this, Castle. And I really am going to reward you for tomorrow’s plans,” she said with a smirk. She took a sip of champagne, put the glass down on a table, and put her hands on the hem of her blouse. She had it off in ten seconds, and then she unbuttoned and unzipped her skirt. She stood before him in a black lace bra and thong. He started to walk toward her, but she put up a hand to stop him. “This is for you, babe. You just watch for now!” So he stood back and watched as she very slowly pushed her panties down her legs and as she took off her bra. And he watched as she sauntered over to him and undid his belt and unfastened his pants. He didn’t take his eyes off her as she untied his shoes and took them off. He smiled at her as she put her hands on the waist of his jeans and pushed them down and then stood up. He looked down as she unbuttoned his shirt and pushed it off his arms. He watched again as she took his boxers off.
She stood as close to him as she could and put her arms around his neck. He put his hands on her butt cheeks and hoisted her up. He leaned down and she moved her head and their lips met in the middle in a smoking hot kiss. He lifted his head for a minute so he could find a bed and spied one through one of the doors in the suite. Kate laughed as she captured his lips again. He carried her into the bedroom and let her slide down his body. He pushed her down and she landed on her back. He didn’t give a minute to adjust – he just lined up his cock and buried it in her pussy.
“Oh fuck, Kate! Your pussy is so hot. Fuck,” he said as he pumped his cock in and out of her. She had her hands on her boobs and was twisting her nipples. They moaned together as she moved her hands to her clit. Now she was rubbing it and she would hit his cock as he entered her pussy. He growled at her and she looked at him and laughed. But that laughter soon changed to a groan.
“Fuck Castle, give me more! I’m so close. Harder, faster, more! Fuck!” He obeyed and his strokes came faster and harder. He knew she was just about to come because he could feel her walls grabbing his cock. The sensations set off his climax and they came together. He collapsed onto her and she loved how his body pushed her deeper into the mattress. When he got his breathing under control he put his arms around her waist and rolled them over so she was on top. She smiled down at him, and said, “And that was your reward for a great idea!”
He laughed as she put her head on his chest and promptly fell asleep. He was too excited at that moment to sleep. The memories of their night with Hunt played through his mind and he hoped that tomorrow would bring them new memories. He fell asleep with a grin on his lips.
