One Chapter Only

Rick and Kate had another dead body. The first one was male while this one was female. In each case casings were found with letters on them. Nikki Will

"Nikki will what?" Rick wondered. Now they were both watching as three large black SUVs came rolling up to their crime scene. "Unless a UFO just landed on the other side of the park…"

"Or else the FBI is here to claim jurisdiction of this case." That wasn't what Kate needed right now. All cops hated the FBI. All of them thought they were the greatest thing in crime fighting, and lowly cops were just that: lowlifes not capable of solving one little murder.

A woman with reddish hair walked up and smiled. "Nikki Heat, I presume?" She sounded friendly enough for a change.

"It's Beckett, Detective Kate Beckett," Kate corrected her.

"Yes, I read all about you in Cosmo. And you must be the celebrity writer tagalong, Richard Castle." Those two had a unique relationship.

Kate was even more uneasy because there was just something off about this FBI agent. She hadn't felt anything like this since… Well, a long time.

Jordan Shaw was not confused about Kate Beckett. She felt her right away which made Castle being here and their partnership all that more interesting.

"Special Agent Jordan Shaw." Jordan reached out to shake Kate's hand and that sealed it for both of them. They both knew now.

"Jordan Shaw? That Jordan Shaw?" Rick knew that name.

"Now, if you don't mind, I'd like to see the body." Jordan needed to do her job first. She could talk to Kate later.

"Agent Shaw, my people have already cleared the area. CSU is on the scene and we're canvasing the park. So, as happy as I am that the FBI has taken an interest in my case, there really isn't much left here for you to do," Kate told her.

"Detective, I'm well aware of what all local police agencies think when the FBI swoops in and takes over. But my orders from the Marble Halls are to assume jurisdiction of this crime. I would love to have your cooperation on this case and I'm asking instead of telling you. However, if you force me to, you'll be lucky to get a job as a deputy sheriff in nowhere New Mexico, or you can go back to waiting tables.

"I'd really like to see that body. Now." Jordan went around these two.

"Tell me everything you know about Jordan Shaw." Kate got in his face. Yes, she was jealous. Castle was interested in Shaw and he was supposed to be interested in her. They had a deal.

"She's like the Federal you. She's good, really good. Just like you are. Cracked open that Hudson Valley Strangler case when she was just 25 years old. You want to know where you could be 5 or as long as 10 years from now? You're looking at her.

"Can we go see the war room now?" Rick went around her and into the room.

(/\)|(\/)

Jordan finally had Kate alone in the conference room. The entire precinct had already been swept for bugs. They'd even found one, but hadn't removed it yet. However, this room was secure.

"So, Nikki Heat, otherwise known as Detective Katherine Houghton Beckett. How long have you been a Succubus, Detective?" Jordan got right to the point. She had a killer to catch and not a lot of time for small talk.

"Is that what I feel around you?" Kate knew she felt something off about her.

"Didn't the woman who converted you teach you anything about being a Succubus?" Jordan was a little shocked. Not greatly, since it was possible that the Succubus that had converted her had done just that, and then left her. It was looking like that was the case with Kate.

"You know I'm a Succubus?" Since Shaw was using the word it wasn't a secret any longer.

"I can feel you, and I'm sure you can feel me. However, I'm betting I'm your first since your conversion," Jordan offered based on her reaction alone.

"Yeah, I've never felt or met another since that day," Kate confirmed.

"Sounds like we may have to have a much longer talk later. For now, give me the basics. Who converted you, where, and when?" Jordan asked.

"I don't even know her name, and I've never seen or felt her again. She wasn't the first woman I'd ever had sex with, so I wasn't that surprised. I had a lover for months when I did a semester in Kiev. If I hadn't come home from that semester, I might still be over there. Maybe married to her if they allowed that kind of thing. We stayed in touch for a while but drifted apart. I have no idea where she is now.

"Anyway, it was a little after mom was stabbed and killed. I had dropped out of college. When mom died, my dream of being a lawyer died with her. Dad and I took her death hard. Dad became a drunk and I couldn't stop him.

"Worse, he was a mean drunk. He still doesn't remember just what he did to me. The bruises are gone, but the memory remains." Kate began there with some background.

"Alcohol has a way of doing that. Fortunately, while we can drink the stuff it doesn't affect us any. It's like drinking water. We can eat food, but we don't need it to live. We need something else to keep us alive," Jordan informed her since maybe she didn't know.

"So I've learned over the years. I was only 19 years old then. She found me. Dad had just beaten me while he was drunk, and I was so depressed. My life had gone to shit, and I couldn't seem to stop it.

"Next thing I know we're having sex. Really great sex, I might add. Maybe not as great as in Kiev, but the orgasms were so much stronger, and we did things. Things I've done before, but this time it was different. I wanted more, I needed more, and she gave it to me.

"All night long for seemingly hours on end. Then come morning she was gone. I can remember the pain. The very first time my wings came out of my back, my tail came out my ass, and my horns came out of my head.

"Then when I woke, and she was gone, I was filled with this need for a man's cum. I just had to have it. It was all consuming. I couldn't think of anything else. So, the first man I spotted became my first victim. I consumed all of him. All that was left was his clothes and his wallet. I used up the rest of him.

"The funny thing was I wasn't really affected by it. I mean, I knew I had killed him, but I didn't care. He had what I wanted, what I needed, so I took it," Kate said.

"Sounds about right. A Succubus, meaning you, and I, and others, only really need a man's cum to nourish us. To keep us refreshed and alive. It gives us strength. Surely you've noticed by now that you're faster, stronger, can go without sleep for far longer than you ever have before.

"You could probably tear this building down with your bare hands if you wanted to." Even Jordan hadn't yet found where her strength and speed stopped. "Of course, you would need to feed instantly if you did, but you probably could."

"So I've noticed. I almost broke Castle's back once. Scared the shit out of me," Kate admitted.

"Tell me about Castle now," Jordan said. "Based on what I've seen so far, you two stick together like glue. Not sure I could separate you two even if I tried."

"We're lovers. He gives me all the male cum I need to live and…" Kate was still a little uncomfortable about their arrangement. Their deal.

"Castle caught me in my Succubus form. We'd just made love to each other, and I really thought he was asleep. He caught me in his bathroom looking myself over. I was still amazed even then just what a male's cum could do to the smoothness of my skin.

"I don't have a mark on me, even now. Practically baby smooth." Oh, how she loved the feel of Castle's hands over her smooth skin. He had a way of making her body glow and tingle. It wasn't just her Succubus side that needed and loved his touch. Kate Beckett did, too.

Jordan nodded. "That's a Succubus for you. How else do we lure men into our trap so we can get all the cum we need? We have to be exquisite to them. A goddess, if you will. To be sexually attractive. As good as we get, we can also give it.

"I'm betting Castle has told you that he's never had such strong orgasms in his life except for when he's with you," Jordan questioned her.

"Yeah. I know I scream, but I can get Castle to scream almost as much. So, that's all Succubus?" Kate asked her.

"We really do need to talk later. It sounds like who converted you was a huntress," Jordan told her.

"A what?" Kate didn't understand.

"Like humans, no two Succubi are the same. Humans have subdivisions; so do Succubi. Think Navy, Army, Air Force, Marines, and Coast Guard for example. For Succubi there are subdivisions as well.

"A huntress hunts men, all men. She cares nothing for them save for what they can give her. She kills them and sucks them dry and gone because she wants to, not because she has to.

"Being converted doesn't just change your body, which is obvious, just look in a mirror. No, being converted also changes the mind. Even if you were revolted by so much as seeing a dead body even in a picture. Now you'll drain a man dry and not care in the least.

"Your need for cum is all consuming, or it can be. Though you've solved that problem all by yourself. You have Castle," Jordan pointed out.

"Castle doesn't even want to make love to me unless I'm in my Succubus form. Did you know you can have an orgasm just by letting him stroke your wings? Boy, was that a surprise and a pleasant one," Kate mentioned.

"You can achieve positions you couldn't dream of doing as a human. Try doing a 69 while you're standing with your legs spread so he has access. That will get the juices flowing. And with your strength the only reason to stop is the blood flows to his head and he passes out." Jordan chuckled over that as she recalled her first time trying that with her husband.

Kate raised an eyebrow. "Speaking from experience, I take it?"

"My husband, and yes, he knows I'm a Succubus and enjoys it. I make sure of that. Our daughter, however, does not. She's not nearly old enough to understand why Mommy has wings, a tail, and horns on her head, and she doesn't," Jordan offered.

"You have a daughter?" Maybe there was hope for her and Castle yet.

"Adopted daughter," Jordan informed her. "A Succubus can't have children. We don't use male cum for that. We use it to feed us, not waste it on trying to make a baby. If we want another Succubus in the world we just convert someone."

"Oh." Then she and Castle were doomed.

"One of you wants kids?" Jordan asked gently.

Kate nodded. "Castle loves children, and he's an amazing father to Alexis. I know he would love to have children. Something it would appear we're never going to have together." She knew Castle wasn't going to take that news well.

"I'm sorry, Kate. I'm pretty sure we don't even have a womb to grow the baby in. If you haven't noticed yet, you can produce a huge amount of juices for lack of a better term. Those juices don't just lubricate, but they're used to help convert a human female into a Succubus."

"I know mostly what we did, I just don't know how to do it," Kate told her.

"You have someone in mind for conversion?" Jordan queried.

Kate rolled her eyes. "I got so used to letting Castle see me as a Succubus that it allowed Alexis, that's his daughter, see me as a Succubus. That was a hard conversation to have.

"Worse, about a month later she had still more questions. Then seemingly out of the blue she asked me if I could convert her to being a Succubus. You want to talk about a shock, and yet I nearly jumped at the opportunity to convert her. But I stopped myself which wasn't easy, I can tell you." The need to convert her was nearly as strong as her need to feed.

"How old is she?" Jordan inquired.

"She turned 16 last October 8, meaning not long ago." Thanksgiving was coming up fast as was Christmas.

"Too young! She needs to be 18 minimum, 21 would be even better. You at 19 was stretching things a bit. Your Succubus will just have to wait, as will she.

"Procreation is a powerful force. The need to create a sister and add her to the Sisterhood can be strong," Jordan admitted. "I've only ever done it once. She's a lovely 22-year-old woman now. Full of life and enjoying being a Succubus.

"Being a Succubus isn't a curse, you know. It's just a different way of life. Humans eat food, and we consume male cum. So long as they grow food, they live. They live, and we live because we need males to provide us with what we need to live. It's perfect," Jordan said.

"At least Castle isn't afraid of me. Nor is Alexis, it would appear," Kate admitted.

"You love him, or you're learning to love him. You're going to outlive him, you know. We're technically Demons, so we'll live a very long time. Eventually Castle and Mark, my husband, will die. We'll live on, and perhaps one day even forget them." Jordan wasn't anywhere near ready for that day.

"So there's no way for Castle to live longer?" Yes, she was willing to begin thinking that she wasn't just falling in love with him, she was already in love with him.

"Well, I know of someone, someone that I haven't talked to in a long time and presently, I don't even know where she is, but she suggested something to me once.

"Now this could be dangerous, and I don't even know what it will do to your relationship with Castle. He may no longer be able to provide you with the cum that you need to live. You may have to go back to hunting for males to get what you need," Jordan cautioned.

"I'm listening." How could she reject it if she didn't even know what IT was?

"Succubi are all females, obviously, and a Succubus is technically a Demon. Just how evil you are depends on you. Who you are or what, before you were converted.

"However, like in life, if there is a female, there has to be a male. And in that case the male is called an Incubus. Basically a Succubus for the other side. He converts males into Incubi, and he needs female cum to survive. We need male cum, and he needs female cum.

"Not sure if we're in competition with them or not. Not sure if I've ever met one or not. If I have they don't feel like us, so unless he told me, I might never have known and he might never have known about me.

"But I would think that I would know if he had the cum I needed to survive. Though maybe while we use our pussy juices for many things, he may in turn produce a large amount of male cum. I don't really know.

"Just don't get your hopes up. I have no idea where she is, or if she even knows. She's pretty much under the radar, and if I can't find her as an FBI agent, she's in hiding or simply really hard to find," Jordan cautioned her.

"What's her name?" Kate asked. "If I've learned one thing in my association with Castle, it's that he knows people. I don't understand how he came to know all those people, but he does."

"Alright, but be careful. Being changed into an Incubus is no game. He finds a way and this just might be the end of you two as a couple, or possibly even friends. Being changed into a Succubus changed your mind. Most likely being changed into an Incubus will change his." Jordan tried one more time and saw Kate just sitting there, waiting.

"Her name is Serena Kaye, and last I knew she was a jewel thief and a damn good one. Of course, being a Succubus doesn't hurt in that profession. It also helps explain why I can't find her. If she wants to be found then you'll find her. Otherwise, good luck with that.

"But you two better have a real heart-to-heart talk before you even try to start looking for her, or an Incubus. And contrary to what you might be thinking, we Succubi do indeed have a heart. Figuratively and literally. I love my husband and not just because he gives me all the cum I need to survive. He's my husband.

"Perhaps one day you and Castle will figure out just how that works. You're not just taking, and he's not just giving. You need what's down here." Jordan pointed at her own loins. "He's interested in what's in here." Jordan touched her chest where her heart was.

"Once you figure out how to give him that while you get not just his cum but also his heart, then you'll be a true Succubus. Not just a Hunter like the one that converted you.

"Demons are evil because they want to be. No one says you have to be," Jordan advised.

At that moment they both heard a knock. It was Avery. He opened the door. "Sorry to interrupt, but we have a lead," he informed them and left.

"Duty calls. We will talk later, Kate, and yes, I'm still in charge around here." Jordan pointed at her. "Don't forget it."

"Like I could ever forget that." Kate smiled at her to show that she didn't mean anything by it.

Jordan headed for the war room while Kate sought out Castle. "We need to talk tonight, Castle. You're never going to guess who around here now is just like me." Kate gave him a clue and looked at Jordan once again with new eyes. "Even more than you originally thought."

"NO!? Agent Shaw is a…" Rick was forced to stop opening his big mouth when Kate poked him maybe just a little too hard in his side. Sometimes she didn't know her own strength. "OW!" Rick rubbed his aching side.

"I'll kiss it better later. Or maybe a little more, if you're a good boy," Kate teased him.

Rick raised an eyebrow. "What if I want to be a bad boy?" he challenged her.

"Then I'll have to spank you before I fuck your brains out," Kate informed him.

"Decisions, decisions." Rick was conflicted. However, he did know one thing. He was in love with a Succubus, and maybe if he found the right ring, he might even manage to convince her to be Mrs. Katherine Houghton Castle. Or Beckett-Castle if he had to.

Kate grinned as she watched Jordan and Avery walking their way. Apparently, they were still on the case even if the FBI was in charge.

Tonight just might be the start of a new and very long and happy life. If it didn't end it for them.
