Kate groaned. It was because as she was waking up, her head hurt. That in and of itself was something new for her. Her head hadn't hurt like that in years, not since her school years. She wasn't known as Rebel Becks for no reason.

Given that her dad turned himself into a drunk, one would think that she wouldn't touch alcohol ever again. Admittedly, since that time she hadn't, but not because she hadn't tried. Because she had. No, her high school years were full of alcohol. Beer mostly, but not always. She had learned how to open her throat and she could chug beers better than most. It was largely a question about how fast the beer left the glass or can. Neither could really keep up with her.

Kate didn't want to sit up, but she did. Headaches like this one just didn't happen to her these days. Finally focusing, she didn't understand just where she was. It didn't make sense. The coloring was bordering on gross. Like 1960s Vegas casino kind of gross. Bold and ugly. Orange, yellow, and some red.

She was on the floor in a hallway. There were pictures of people on the wall. Not paintings, but they were more of a high school-like photo, and she thought she saw names under them.

However, she wasn't alone. "Castle?" Kate poked him to wake him up, but he didn't. "CASTLE! WAKE UP!" This time she gave him a bit of a punch to his arm to wake him up. That seemed to have done the trick since he groaned.

"Oh…my head!" Rick hadn't moved and didn't want to. Actually, he was afraid if he did sit up right now, he would lose the contents of his stomach. "What did I drink?" It was all he could think of that would cause that kind of a headache.

"We have trouble, Castle," Kate told him and kept looking around. Two hallways, an open central staircase with wood posts, beams, and that same ugly carpet. The hallways were filled with glowing…fires? Probably light bulbs that looked like open flames. The walls were an ugly puke yellow. Who painted walls that color? Who even thought making that color was a good idea in the first place?

"Where are we?" Rick still hadn't moved, but at least his eyes were open. "This isn't the precinct. Not unless Roy has done a lot of redecorating. In which case, I'm going to suggest that he fire the decorator and refuse to pay for this." Rick hated what little he could see of it from where he was.

"I don't know where we are. What's the last thing you remember?" Kate wasn't ready to try standing just yet. And she didn't see anyone except Castle.

"I was… I was in the precinct. I think I'd just told you that I had to leave and drive Alexis to Princeton, but I would be back for my surprise going-away-for-the-summer party. You had this strange look on your face, but I was in a hurry." Rick chose to sit up, and he instantly regretted it.

He took a guess to try and explain his headache. "I thought it would be just beer. What was in that punch anyway?"

"There was no punch, Castle. You had only…only just left and I was on the stairs, I think. Now we're here. Wherever here is." Kate was ready to stand up and did so. Finally, her head was starting to clear.

There were definitely two hallways, and both had doors on either side. It felt a lot like a hotel. But what were they doing in a hotel? An ugly hotel trapped in the 1960s, no less.

"Come on, get up. We need to figure out just where we are." Kate held out a hand to help him up. She had more than enough strength to pick him up, let alone to help pull him up.

For the simple reason that she asked, Rick reached up and took her hand, but he didn't notice that it was all her that had him on his feet.

"Hotel?" Rick looked down each hallway, and finally, he saw the stairs. And a plant in the corner along with a bowl half-filled with red apples that he initially assumed were plastic and not edible.

"So it would appear." Kate watched Castle walk over to one of the walls filled with pictures.

"Lucy Gold, Benny Goldman, Heather Locklear. Obviously no relation to the actress. There's something off, Beckett." Rick's headache was just about gone now. That had Kate joining him to see for herself.

"There are names, not full names, mind you, but you would expect it to say something like Employee of the Month or Alumni. Chief of Operations, something. Those are just names with photos that suggest they stood there and had their pictures taken." Rick had a mystery.

"Like in a high school yearbook," Kate commented.

"Yes, something just like that." He moved down to a few more. "They're all the same. Just names and nothing else." Rick ceased looking at photos. They weren't helping them figure out where they were.

"Looks like a hotel. But who builds hotels that look like this?" He didn't like it if it was. Definitely not his style.

"We're getting out of here, whoever's hotel this is." Kate took out her cell phone to get some help. Frustrated, she looked at him. "My phone's dead. It doesn't turn on."

That had Rick taking out his phone to try. "So is mine. It refuses to turn on." Then he worked at getting the back cover off. "The battery's gone!" He showed it to her. Kate joined him and let him take her phone after he gave her his and opened her phone. "No battery." Rick looked at her in a bit of a shock.

"Who removes batteries but leaves the phone?" Kate didn't like that at all. It wasn't looking good.

They traded their dead cell phones, and then Kate decided to check her weapon. She seemed to have everything. She had her shield, cuffs, wallet, radiation detector, and Glock. She ejected the clip to check it. "No bullets!" Kate showed him the empty clip and let him take it from her. He tested the spring and watched as it worked perfectly.

"Spare clip?" Rick asked.

"I'm lucky I even have my Glock on me. Usually I put it in my desk drawer when in the precinct. I only take it out when I'm leaving the building. And no, I don't carry around a spare clip in the precinct." Kate took her empty clip back, slapped it back into her weapon, and holstered it.

Rick was becoming concerned. "Now what?"

"We get out of here. Downstairs. Every hotel has a lobby where you check in, meaning it has a front door." Kate headed for the stairs and expected Castle to follow her like always.

Downstairs they spotted the check-in counter with a wall of boxes – the room rack – behind it, but none of the boxes had keys. "What hotel with rooms doesn't have keys?" Rick looked over the counter on the desk. "There isn't even a pen to sign in with."

"Come on, we're leaving." Kate noticed the front door. The glass door looked like a glass door with windows on either side. Except she couldn't see outside.

Kate hit the door to get it to open, but it refused to budge.

"Locked? Maybe you pull instead of push?" Rick suggested.

"It says PUSH!" Kate said through clenched teeth. She pushed again but got nowhere. She was thinking of breaking the glass right about then.

"Phone," Rick offered and went over to the front desk to look for a phone. "PHONE!" Rick saw one, but it was on the other side of the counter. Instead of finding a door, he jumped up and climbed over the counter to reach it.

"Very athletic of you, Castle," Kate teased since watching him do that was good for a chuckle.

Rick ignored her comment and picked up the old-style phone. It was a rotary-style phone. Not even a single push button. He heard nothing. There was just dead air, so he dialed zero, listened, and still heard nothing.

Now he was pressing the little white buttons that would hang up the phone, attempting to get it to wake up. "It's dead. There's not even a dial tone. And who uses rotary phones these days anyway? This thing is an antique." Rick hung up and decided to pull the cord to see if it was plugged into an outlet. Moments later, he showed her the end of the cord. "It's not even plugged into anything. It's just a cord. There aren't even any wires, let alone a plug to plug into a wall." Rick reached over the counter so she could see for herself.

"What's going on?" Kate glanced around the lobby.

Suddenly the speakers started playing music. It vaguely sounded like 1960s elevator music. All instruments with no singing. "Castle?" Kate looked at him.

Rick held up his hands. "I didn't touch a thing this time, promise."

"Office," Kate pointed, and while he walked toward the door, she hopped over the counter in one sideways jump, landing on her feet with ease, and was right behind him.

"Beckett?" Rick turned to see if she was coming and found her right behind him. He didn't know how she had done that, but at least she was here, so he opened the door.

Inside was an office. There was a desk, one chair, a bank of metal filing cabinets, and on a shelf on the back wall was a receiver like for a radio, and the lights were on. Kate picked up the radio to see what station it was on or to what it was connected. In the meantime, she could hear Castle opening a filing cabinet drawer.

"Where are the wires?" Kate was holding it in her hands after talking it off the shelf. "Castle, it's not even plugged in. It doesn't even have a wire to plug in." Kate turned to look at him and held it up for him to see.

"All of these drawers are empty, Beckett. Every single one." Rick opened yet another one and saw it was just as empty.

"How is this thing even working?" Kate put it back on the shelf and found the toggle that said POWER, so she flipped it. The music stopped, and the lights in the unit went dark.

"This is really weird." Rick closed the last empty drawer and turned to look at her.

"The emergency door! It'll sound an alarm." Kate left the office and saw the door leading out that neither of them had used. She strode down a hallway toward a red sign that said EXIT!

Kate hit the door release expecting the door to give and open up, but it didn't. It didn't budge, so she hit it again and got nothing. She was beginning to get more than a little angry, so she stepped back and kicked it with her foot. It sounded like a solid hit, yet the door didn't open.

"Locked?" Rick asked since he was right behind her.

"It's an emergency exit. They can't be locked." Kate kicked it again. This time she put a little more strength into it, but she got the same result.

"Maybe it's welded?" Rick stepped past her and examined the door to see if it was welded shut. Kate watched him for a moment and then turned to look behind her to check her six.

"Beckett, this isn't even a door. There's no gap. There's nothing to seal." Rick made way for Kate to see when she pulled him aside to look for herself.

"It's a wall! It's just a wall that looks like a door. What the hell is going on, Castle?" She hated feeling trapped, and right now, she was definitely feeling trapped.

"Check the doors. We're on the ground floor. Each of these rooms has to have a window and maybe an A/C unit under the window." Kate moved decisively to the door and opened the first one she came to, not caring what the room number was.

Inside she found a bed with a comforter and pillows, all of which appeared unused. On the far side were drapes that were closed and an A/C unit. So, around the bed she went and yanked the curtains to each side. Instead of a window, she saw a wall. "What the hell?" Kate hit it a little and it felt solid. This time, she ripped the drapes down to see all of it. The paint ended at the window, except there was no window.

Kate heard the toilet flush which had her moving to the door that must be a bathroom and watched as Castle turned the water on at the sink. "There's water," Rick stated and looked around. "Do you see anything missing?"

"You mean besides a window?" Kate asked.

"I mean no soap, no little shampoo bottles, not even a cup encased in plastic to show that it's clean. There are towels, but there's nothing else." Rick looked at Kate because he didn't understand this place.

"The lamp next to the bed is on. The light and exhaust fan in here both work, and the water works. We're breathing air, and it's not too cold and not too hot." Rick looked around.

"Do you see something else missing?" Rick saw it even if Kate didn't.

His question had Kate looking around. "There's a phone, alarm clock, light, bed, comforter, ugly picture on the wall. The color scheme is terrible. The carpet reminds me of carpet in a casino. Everything looks old, like 1960s old."

Rick ran his finger across the door sill leading to the bathroom and showed it to her. "No dust."

That had Kate doing the same at the door to the hallway and got nothing. "Nothing is that clean, Castle. Nothing."

"Maid service? She needs a raise if she can do this," Rick said.

"Laundry room." Kate left that room to go looking for it. She opened the room door next in line on this wall and took a quick look. Rick did the same on the opposite wall all the way down.

"Anything?" Kate inquired when they reached the lobby and watched him shake his head.

"Every room was the same. Just like that first one," he remarked. "Even the color scheme was the same."

"I don't get this place. Laundry room, something." Kate cast about, looking for a new direction to go to search somewhere else.

"This isn't the laundry room." Rick followed Kate through a door and straight into a dining room with tables covered by white cloths. There were seven in total, and each had six red chairs with metal legs. There was even a bar that might serve drinks.

This room had the same ugly carpet; yellow had given way to gold accent walls. There were plain, ugly lights no one had seen since the late 1960s, and for good reason.

"You know if, there's a dining room," Rick began thoughtfully.

"There's a kitchen." Kate had a new lead, and she strode across the dining room toward the far wall. It had two doors side by side with a small window in each of them. Kate stopped at the door and peered through the window first. She didn't see anyone, so she pushed, and the door swung open, exposing a kitchen, a commercial-size kitchen.

Kate went left while Rick moved to the right. "Anything?" Kate queried. She ate so little these days and for good reason. Castle kept trying to get her to eat something. She didn't need food. She didn't need all the coffee she drank. It was just like the taste of what little she did eat, and she loved coffee, even if she didn't need it.

"Just a lot of kitchen equipment. Gas-fired." Rick turned a knob, watched the flame ignite, and turned it off again. "It works."

"There's no food. I mean, no one's even trying to make anything. There are a lot of plates, glasses, silverware, and pots and pans, but no one's cooking anything. And the place is clean, a spotless kind of clean. I'm even betting you could eat off of this floor." Kate slowly walked around and heard Castle open a walk-in cooler and joined him.

"There's food. Lots of food." Rick stepped inside and picked up some romaine lettuce, and sniffed it. "It's fresh." He put it down. "Apples, oranges, eggs. You name it, and it's in here. And it all looks fresh. Like it was just delivered." Rick came out, closed it, and opened the one next to it.

"Freezer." Kate could feel it from where she was standing.

"Beef, steaks, pork chops, lamb chops, chicken, whole chickens, and several varieties of fish. None of it's sealed in a vacuum, but it all looks fresh." Rick picked up a package of ground turkey. "No names, nothing as to who packaged it. Who sold it?" He came out of the freezer, and Kate closed the door. He went back to the walk-in cooler, opened it, and went back inside.

"You see any names anywhere? Where did all this come from? Brazil? Canada? The Philippines, even? Nothing says anything. I know what it is by just looking at it, but there's nothing to tell you what it is." Rick looked at her and watched her turn to look in the kitchen itself.

"Backdoor." Kate pointed to the sign that said EXIT. It, however, turned out to be just like the other door. It didn't open, and after examining it, they could see it wasn't even a door at all.

"This place is pissing me off, Castle." Kate was getting angry.

What Rick wanted to do was to hug her, but he was sure she would fight it. He had tried three times to talk her into coming with him out to the Hamptons. He wanted her to stay just for the weekend, or for a week. All summer, but she had said no each time.

Then he had caught her in a lie, saying that she didn't have any vacation time. She planned to spend an entire week with Demming at some beach cabin a friend of his had. And Kate was going.

That told him he was out, and Demming was in. If that was what she wanted, Demming could have her. He was going to go to the Hamptons and never come back. To New York City, yes; to the precinct, no. To her, definitely not. He was going to cut his losses.

Kate had to get out. She was going to need something soon. Castle had what she needed, but he didn't know. No one knew, not her dad, not Lanie, not the boys, and certainly not Demming.

The kitchen was a dead end, so she left it to search for a way out of this place.

OxxoxxO

According to her dad's watch, since they'd woken up, they had been there for twenty-four hours. They had checked everything. There was nothing in the laundry room. Every door that said EXIT wasn't really a door.

Right now, Rick was on his back in his clothes, sleeping. They had been up for hours, and he was beat. Kate didn't need any sleep yet, so she was out of his room, looking around again. They had yet to see anyone else.

The music had suddenly come back on, and that had Kate racing to the office, leaving Castle in the dust. He hadn't said anything about her speed, but her secret wouldn't stay that way for much longer.

There was a reason why she had a lot of one-night stands, a whole lot of them. Even Demming was almost a one-night stand. Her secret was just that, a secret, and she needed to keep it. But if she stayed there much longer, it wasn't going to be a secret.

OxxoxxO

"Did you get any sleep?" Rick was up, and while he was willing to give up and watch her choose Demming, he still cared.

"I'm fine." But she wasn't. She could feel the pain and feel the need building. There were only hours left before the pain and need would increase to the point where she would have no choice but to do what she didn't want to do.

If she was pushed to that point, and drained Castle dry to satisfy her need, she wouldn't just end up killing him. Kate would be killing herself as well. If she couldn't get out of this hell, it meant a very pain-filled death for her.

"Come with me, Castle. We need to talk." They hadn't found a way out, and her need was growing. Kate took him to the dining room. He had food to eat and water to drink. Castle alone had what she needed.

"Sit down, please. I have something to tell you." Of all the people to know, she thought he just might believe her. He was certainly going to believe her after she showed him.

Kate, though, couldn't sit. She was nervous. "Please try not to interrupt me. Alright, here goes. No one knows what I'm about to tell you, no one; not my dad, not Lanie, no one. I was nineteen years old when my mom died. Dad turned to alcohol and became a roaring drunk. You know all that. But there's something you don't know. When I was depressed and feeling sorry for myself, my world was going to shit. And I met someone.

"She was different, different in a way that I never imagined. If anyone had asked me, I would have said with conviction that she didn't exist. Anyway, we had sex, lots of sex, all in just one night. It was the best sex I've ever had. My orgasms were the most powerful I'd ever had, before or since." Amazingly, Castle just sat there and didn't say a word for a change.

"That sex changed me. She changed me. I don't eat food or drink because I need to. In fact, I could never eat or drink anything ever again, and I would be fine so long as I got the one thing that I do need." Kate was doing her best to try and explain.

Now it was time for the hard part. Kate looked down at the floor before talking to him. "I need a man's cum, Castle. That's all I need to stay alive. I'm a Succubus." There, she'd told him. But he just sat there and said nothing. "You can talk now. I'm not forcing you not to talk. I'm trying to make sure I'm not pumping out any pheromones that would cause you to be horny and want sex with me. I don't want to control you."

"Succubus? As in a Demon Succubus." Rick raised an eyebrow. "I like the idea of believing in Demons, and I may tease you about Zombies, Ghosts, and even Aliens. I believe in Santa Claus. So, what is it that you're trying to sell me here?"

"Yeah, I knew this was coming. Fine. Just don't get scared and run away. It's not my intention to hurt you." If anything, Kate was learning to like him. It was just that she had a secret, and if he knew, he wouldn't want her anyway.

"Here we go, don't run." Kate began taking off all her clothes. She couldn't do what she needed to while fully clothed.

Rick raised both eyebrows as Kate stripped in front of him. He thought about stopping her, but he was interested in how far she was willing to go. Stop at her bra and panties, and then what?

Except she didn't stop until she was completely naked. And while Rick thought she was beautiful when fully clothed, she was even more so nude. No, her breasts weren't large, but he knew that already; he wasn't blind.

She even had a bald pussy, just as he liked it. "God, Kate." He had so much he wanted to say to her. She didn't look like a Succubus. She looked like a beautiful Kate Beckett. Was that what Sorenson got to see? Was that what Demming got to see?

"Don't run, Castle." Kate closed her eyes, took a deep breath, and willed herself to change. It only took seconds. Before he could even breathe, she was standing there with a reddish skin tone, large red and black wings, a long tail, and small horns on her head. Her hair got longer and changed color from brown to jet black. But what really had his attention was the size of her breasts. He had been guessing 35B at best. Now he was reckoning she was a 36D or maybe 36DD, but not larger.

"Beckett?" He was utterly amazed. She looked just like a Succubus was supposed to look in all the illustrations he had seen of one.

"I'm a Succubus, Castle. This is my big secret, and I'm really sorry, but I can't hold back my pheromones any longer. I need a man's cum to live; you have what I need to live. The pain of withdrawal is getting bad. Without a man's cum, I'll die. Soon I won't have a choice. I'll rape you and kill you, and if I can't get out, I'll die too.

"Please understand. I don't want to hurt you, but I need you." A blood-tinged tear slipped down Kate's cheek.

That was when Rick felt his cock enlarge, and for a reason he didn't understand, he really wanted to fuck her. He desperately needed to be inside her.

"You can feel my pheromones now, can't you? I can see the change taking place. You want me, want to force me to the floor and fuck me. Just nod your head." In all likelihood, he was speechless by now, and Kate watched as he nodded.

She got down on her hands and knees with her pussy facing him. "Drop your pants, Castle, and fuck me. I need your cum inside me so badly now. Please? I promise not to drain you dry. Just fill my pussy with your cum," Kate begged him before she was forced to do something she didn't want to do.

OxxoxxO

Rick was holding a naked Succubus in his arms. Complete with wings, tail, horns, and big, perfect tits.

Kate had been fucked a lot over the years, but never had anyone make love to her. That was what she was willing to call what Rick had just done.

Rick had fucked her in the dining room just like she needed. From there, they'd migrated to one of the rooms where she had given him a blow job, and he had countered that by making love to her. Beginning with sucking on one of her big toes, he kissed his way up to her pussy. She had climaxed when he'd fucked her. However, what he had just finished doing was something else.

Absolutely no one had ever found her G-spot, but Castle had. And even she couldn't begin to count the number of orgasms she'd had, thanks to him.

Kate was on her side with her head propped up on one hand while she doodled on his chest with her other hand, and her tail was stroking his cock to see if he had one more round in him. She had done her very best not to drain him dry. Thankfully, when he climaxed, he really climaxed and filled her up nicely.

"So your big secret is that you're a Succubus, huh?" Rick was on his back and was letting her touch him.

Kate nodded. "Yup, pretty much. Thank you for not running."

"And miss out on my chance to make love to a Succubus? You must have lost your mind!" Rick smiled lazily at her.

Kate grinned back at him. "Pretty sure I did that already." All those orgasms had definitely caused her to lose her mind.

"Can you tell me what, if anything, Demming knows?" Rick was curious.

"You're the only one who knows. I hypnotize Demming before I fuck him to get his cum. Usually, I only have a one-night stand to get what I need to live," Kate answered.

"I'm honored, Beckett. Tell me, why did you explain and show me?" Rick wanted to hear the right thing from her.

"You scare me, Castle. I could feel myself falling for you, but I'm a Succubus. I couldn't risk falling in love with you. I can't have children, so I can't have a family. All I can be is a Succubus."

"Then you used Demming to try and drive me away?" Was that why she was with that shallow jackass?

"Pretty much," Kate admitted. "It was all I could think of."

"It almost worked. I was going to go to the Hamptons and not come back," Rick said.

Another blood-tinged tear ran down her face. "I'm sorry," she whispered. "So, what now? We're trapped here. You have food, you have water, and you have cum that I need."

"I know what I do want." And Rick was willing to tell her.

"Oh?" Kate asked.

"When we get out of here, I want to date you. I'm more than willing to give you all the cum you need," Rick told her. "You just have to be willing to let me make love to you as a Succubus."

"You want me?" Kate stopped doodling on his chest and laid her palm on him. And she stopped her tail from stroking his cock to see if it would wake up for her.

He reached up and pulled her head down to him so he could kiss her. "Does that answer your question?"

Kate began to smile. She was a Succubus and had long since given up ever having a boyfriend as a lover. She'd only had sex with an endless number of men to get the seed she needed to live.

"Alright," Kate murmured and leaned down to kiss him. Her fears were swept away. If this worked, she would never need another one-night stand. She had a boyfriend and a lover. Kate could allow herself to fall in love with him.
