Well, here it is. I hope the buildup was worth it. Sorry about the one day delay, but I got busy with a couple of projects that needed to be completed before the weekend. Enjoy! Gregg.

Kate smirked at his instant use of his safe word. "You really need to work on getting some backbone, Castle," she told him. "You whip out your safe word at any little thing."

Castle's eyes bugged out. "You call that thing little?" he squeaked in a very high pitched tone. "I think our definitions of little are a bit different, Detective."

"Castle," Beckett chuckled. "You've been in adult stores before. You know they make these bigger than this. I've even had a couple in the past that were a little bigger than this. This one even vibrates," she informed him as she pressed a control on the base.

"Be that as it may," Castle said as he cleared his throat. "You are not using that thing on me. No way, no how. Richard Castle is an exit only kind of guy!"

"Spoil sport," Kate said as she opened the bottle of lube and drizzled some on the phallus. She spread the viscous fluid all over it with her hand, teasing Castle as if she were giving a guy a hand job.

"Uh, Kate," Castle said with some real fear in his voice. "I said APPLES, you know."

"I know," she replied as she concentrated on teasing him with her hand job on the dildo.

"It is my safe word, Kate," he added the obvious.

"I know," she agreed.

"Then what are you still doing with that thing?" he asked in as normal a tone as he could muster. "I'm getting a little freaked out here.

Kate looked up, a sexy smile on her lips and a glint a heated arousal in her eyes. "I'm going to give you a little show, Kitten," she informed him.

Castle's mouth fell open when she said that. "A show?" he squeaked, the high pitch having returned.

"Mmm hmmm," Kate said as she leaned back and spread her legs, giving him a perfect view of her pussy, the lips of which spread slightly giving him a hint of the glistening pink tissues they hid. "Have you ever seen a woman use a sex toy aside from some porno, Castle," she asked in a husky voice as she brought the toy down to her folds and slid the tip up and down her slit, gathering some of her own moisture to add to the lubrication already on the toy.

He wanted to say yes, and be some ultra hip been there done that kind of guy, but frankly that was one adventure he had yet to witness. Not that he had deliberately avoided it, but the women he'd been with, even some of the wilder ones, hadn't given him the opportunity.

"No," he admitted, adding a puppy dog pleading look.

"Well in that case, this is your lucky day," Kate groaned as she pressed the dildo inside of herself a couple of inches. Her eyelids fluttered as she spent a moment working the toy in and out, adding depth with each in stroke. Finally she had the full length buried inside of her and she opened her eyes to look directly at Castle whose own eyes were glued to what she had between her legs and inside of her. "Like what you see, Castle?" she asked, her voice huskier with arousal than she could ever remember. She'd never masturbated in front of anyone before, and she was finding that doing so in front of Castle was a very pleasurable experience.

"You have no idea," Castle shuddered as he pulled at his cuffed wrists. Mr. Happy was straining now, and he felt the worst case of blue balls ever rapidly approaching.

Kate chuckled in the same husky tone as she turned on the vibrating function and began to fuck herself with the dildo. The feel of it going in and out of her slick, tight pussy was wonderful and she had just the right angle to hit her g-spot on every other stroke. Never one to deprive herself of her own pleasure, she got into it as thoroughly as she did everything she did in life. That meant Castle got quite the show!

Castle couldn't believe what he was watching. Kate had told him when they first met, or rather implied, that she would rock his world and amaze him if they had hooked up, and now he was ready to state categorically that that was a perfect example of massive understatement. The sheen of sweat on her body as she worked herself toward orgasm, the heavy breathing, her heaving breasts, and sight of that vibrating dildo going in and out of her tight pussy all worked to get him into a frenzy of his own. Her dirty talk was also spectacular! Especially when she would tell him "I can't wait to have your cock inside me fucking me so hard!" He tried to convince her that he was more than ready, and so was Mr. Happy, but she told him in no uncertain terms that he was being punished, so shut up.

"Oh, God Rick I'm almost there!" she panted. "I'm going to cum so hard all over this cock! Then it'll be your turn!"

Castle held onto his control as well as he could, but that last shouted sentence did him in and he exploded, his cum shooting up and all over his abdomen. Right when he did so he heard a high pitched scream and looked over and saw Beckett spasming all over, the throes of orgasm having taken over all of her bodily control. It was magnificent! Before he knew it he passed out from the sheer pleasure of it all.

About twenty minutes later Castle woke up, a warm tingling sensation coursing through him as he realized that one he wasn't alone and two (when he raised his head and looked down) he saw and felt Kate Beckett blowing him. Even though Mr. Happy had done his duty (albeit solo) just a little bit before, he was up and happy once more under the expert oral guidance of Beckett. When he tried to move his hands down to her head he discovered that he was still cuffed to the bed.

"Uh, care to let the rest of the class participate?" he asked, the weariness of his body evident in his tone. He jangled the cuffs for emphasis.

Kate smiled as she let him slip from her mouth. She'd been enjoying giving him a blowjob, but could take a moment to let him in on a little bit of info. "Sorry Castle, but I'm in charge for now," she told him.

"Excuse me?" he said, not sure he heard her right. He could understand earlier, but come on! He wanted to show her what kind of skills he had, too!

"You're being punished, Kitten," she said, the husky purr back in her voice. "That means I'm in charge."

"I am definitely going to look for another pet name," he muttered as his eyes rolled back when she took him in her mouth again.

Kate bobbed her head a few more times and then let him go, straddling his hips, her pussy settled along the length of his cock.

"Okay, how about Tiny?" she teased.

"Tiny?" he cried indignantly. "I was thinking more along the lines of Studly."

"But I don't have any proof of that yet, Tiny," she teased unmercifully.

Castle's eyes narrowed. "It's Studly, and you'd know that if we could get on to the next level of activities."

"Oh, you mean this?" she asked, feigning pure innocence as she lifted up, guided his length to her entrance, and plunged down hard, impaling herself on him. She'd prepared herself with the dildo just a while before, so it wasn't so much of a shock. But damn did he fill her up, though! "Oh, fuck you feel so good inside me, Castle!" she said huskily in his ear as she leaned forward. She sat back up and began rising and falling letting him slide in and out of her tight pussy. She used her inner muscles to clench and unclench him, showing him that she had some serious skills. She knew that when she finally released him the weekend would be long, strenuous, but incredibly satisfying.

"Oh my God, Kate, you feel incredible," Castle managed to stammer as he felt her surrounding him, squeezing him, and rushing him along to another orgasm.

Kate sped up her movements and let the arousal build to a fever pitch. She knew he would only last a few more seconds, despite the earlier release, and she wanted to explode with him. She reached down and pressed on her clit and screamed his name as she came hard, and felt him lengthen and swell inside her, shooting his load deep inside. She rode him slowly, coming down from her orgasm and breathing hard until she slumped over his chest. She could feel his haggard breathing, and enjoyed feeling his heartbeat under her cheek. Finally she lifted her head and smiled at him a bit blearily.

"Do you feel sufficiently punished?" she asked, a chuckle in her voice.

"You are a Goddess," he told her, a dreamy smile on his face.

"A Goddess, huh?" she asked, her smile widening. Now those were the kind of compliments after making love with a guy that she could listen to all night and day.

"In every way," Castle assured her. Then he pulled at his bonds. "Now can I please have these removed so I can show you what I'm feeling right now?"

"I guess you've earned it, Studly," she chuckled, reaching up with the key she'd reached over and grabbed. She unlocked the cuffs and was expecting him to flip her over and begin to ravish her, which she was looking forward to. Instead he did something even better. Castle wrapped his arms around her and kissed her deeply.

"You can punish me anytime," he told her and laid back, Kate still in his arms. He decided to not mention her use of a new pet name for him as he didn't want to jinx it.

"And the best part is we have all weekend to enjoy it," she told him as she laid her head back on his chest. They were both pretty wiped out from round one. Slipping into sleep, she smiled thinking about all the fun they would be having from now on.

Epilogue:

Monday morning came bright and early. As usual Kate was the first one in of the team, and Ryan and Esposito came in about an hour later. They looked miserable. The tired, haggard expressions on their faces, as well as the circles under their eyes spoke of a miserable weekend. She didn't say a word. About half an hour after they dragged themselves in Castle showed up. He had coffee and bear claws for her and himself. He had a wide smile on his face and a spring to his step. She smiled with the knowledge that she had been the one to give him the smile and bounce.

"And how was your weekend?" he asked, a slightly husky tone in his voice. He asked her quietly, though.

"Perfect," she told him, a little of the arousal she always felt around him in her voice. "And yours?"

"Pure perfection," he informed her. He looked over at Esposito and Ryan. "What's the problem with them?"

"I don't know," Kate replied. She raised her voice. "Hey you two! What's the matter?"

Esposito and Ryan walked over to them and sat down.

"Lanie and Jenny were a bit pissed about us going into that club, and then the whole ogling stuff," Esposito said.

"So they decided that they would take us to a male strip club Saturday night and last night so we would have to watch them ogling all the male talent," Ryan added.

"They closed the bar at the club each night and then we all wound up at Lanie's where she and Jenny had a girl's night the rest of the night and they had me and Ryan sleeping on the pullout bed on the couch," Esposito concluded. "Both nights. My back is killing me."

"I woke up with the worst headache I've ever had," Ryan told his woes.

"And a serious case of blue balls," Castle stage whispered to Beckett who laughed out loud.

"It's not funny!" Esposito shot back. "Because of you our honeys think we're a couple of perverted creeps. Do you know how long it's going to take us to get back in good with out significant others?"

"And I'm getting married in one month!" Ryan hissed. "This is going to make the honeymoon a pretty boring vacation!"

Beckett stood up along with Castle. "That's what you get when you are looking at a woman inappropriately, Boys," she told them, deciding not to get upset anymore that she was the woman in question.

"But Castle caused the riot!" Ryan complained.

"And he was punished for it by me," she told them.

"That right, Bro?" Esposito glared at Castle.

"I was punished severely and it scared the crap out of me," Castle said solemnly. He left out any of the details, such as having a dildo waved at him and all that. There were some things better left in the past, after all.

"And he's going to be getting punished for a long time to come," Beckett told them. "Come along, Kitten." She used his old pet name in the station since they all knew about that one, and she was not about to hyper-inflate his ego by calling him Studly in front of everyone.

"Before you say it you're still more whipped than Castle is, or ever will be," Esposito told Ryan as they watched Castle follow Beckett like a lost puppy.

"I am not whipped!" Ryan hissed.

"Keep telling yourself that, Bro," Esposito said as he went back to his desk to get back to work. He vowed never to do surveillance of an adult club ever again. The price was too high when things went South.

A/N: Well, there it is. I hope you enjoyed it all. Thanks for all the reviews, and I look forward to what you have to say on this one. Gregg.
