You're a knight with a big dick.

You're the best there is at what he does, and you can't wait to get started on this mission!
The next day, you wake up early in order to make it through your first training session as quickly as possible. The knights are all lined up before you ready for their first lesson.

During fifth period, you start to feel really tired. You were sleeping with your shoes on last night, so you didn't get a lot of sleep. You're also not that hungry anymore. In fact, all you want to do is go to sleep.

"Alright, class, today we're going to pass out the tests we've been working on," your teacher says.

Oh joy. You have to take a biology test today. You've been looking forward to it about as much as an African American would be to enter a confederate rally. The teacher passes your desk and drops off a test. As she does, she notices you're not feeling well.
"Hey, are you alright?" she asks.
"I don't feel well," you say, rubbing your head.
"Maybe you should go see the nurse."
"I just need to sleep."
"Alright, go ahead and head down the hall. Just don't go too far, you still need to take your test."
"Thanks," you say, grabbing your stuff and standing up.

You walk slowly out of the class, shuffling along the hallway towards the nurse's office. You put your hand against the wall to steady yourself as your walk. You feel like someone's poured a bucket of sand inside your skull and are slowly pouring more in. By the time you reach the nurse's office, the sound of the bustling hallway has given way to a loud ringing.

The nurse takes you into an examination room and asks you what's wrong. You try to tell her, but as soon as you open your mouth to speak, you realize you don't know how to explain it. You try to think of how best to describe the feeling, and nothing comes to mind. By the time you reach the nurse's office, you're already having a hard time keeping your eyes open. Thankfully, the nurse is there to greet you. She's a kind older woman who takes care of everyone when they get sick or hurt in school.

"Why hello, what can I do for you?" she asks.
"I don't feel well," you say, yawning.
"I gathered that, dear. What's the problem? Headache? Stomach ache?"
"Mm... All of it... And more... So much more..." you mutter.

The nurse tells you to open your mouth, and looks at your throat, eyes, ears and your head in general. She then has you lay down on a cot and begins pressing firmly on parts of your stomach.

"I'm not getting anything out of the ordinary. How long has it been since you've eaten?" she asks.
"Breakfast... Maybe... don't know... Time is relative... in space..." you say, your words becoming slurred.
"Hey, stay with me here. When did you eat breakfast?"
"Two... Two days ago..."

The nurse looks at you with a worried expression. You've probably been dehydrating for a while now. She helps you lie down on the cot and puts a blanket over you.

"You need fluids in you," she says. "I'm going to get an IV started. I'll be back in a minute. Don't go anywhere. You hear me?"
"Hm... I won't..." you say, already half asleep.

The nurse smiles and leaves the room. You snuggle into the blanket and begin to fall asleep. Just as you're about to black out, the nurse comes back in. She has a syringe in her hand. She sits down on the side of your cot and, without any warning, plunges the needle into your arm.

"Hey... What are you...?" you ask, before falling unconscious.

You don't know how long you're out for, but when you wake up, you're in a hospital bed. Your arm has a bandage wrapped around it, and there's an IV in it connected to some bags of liquid hanging beside you. You sit up and find that not only are you quite groggy, but your head is killing you. With some effort, you stand up and take a look around the room. You notice another bed, empty and covered with a blanked, across from you. It looks like it was recently occupied, as there's an IV stand next to it with a bag of clear fluid hanging from it.

Other than the two beds, the room is mostly empty. There's a door leading out, and a window up near the ceiling, which is shaded by the roof. You notice the sky outside is beginning to darken, so you must've been out for most of the day.

A chill goes up your spine as you notice another door in the room, one you didn't notice before. It's standing open just a crack, and a sliver of darkness is peering out from the bottom.

"I have to get out of here..." you whisper.

The door opens up slowly, and a young girl steps inside. She can't be any older than you, dressed in a simple dress. A little too young to be in university, let alone in this old abandoned hospital. Her long black hair goes down to her waist and frames her young face. Her skin is fair, almost as white as the dress she's wearing. Her eyes are grey and dull, and her lips are a pale red. There's something off about her, something that makes you uneasy.

"G-get out of here!" you say, "This is my room!"

The girl just stares at you for a moment, before walking over to the IV stand. She starts playing with the tubes, moving them around her finger. You want to yell at her to stop, but find yourself unable. At first glance you think she's human, but there's something else about her. Something almost unnatural about her.

"What are you doing here?" you ask, instinctively taking a step back.
"You're the new one, aren't you?" the girl asks, ignoring your question. "I saw you when they brought you in."
"That... That's right," you say. "Who are you?"
"I'm Yvette," the girl says. "I've been here for a long, long time."
"How long?" you ask.
"Oh, I don't know," Yvette says with a giggle. "But I know every face that's passed through this hospital. Except yours, of course."
"My name's Anon."
"Hi, Anon," Yvette smiles.

She takes a step forward towards you. The closer she gets, the more uncomfortable you feel. You take another step back, and knock your leg into the bed frame behind you. Yvette continues to move forward, then leans in towards you as if to kiss you.

"What are you doing?" you ask, recoiling slightly.
"I want to kiss you," Yvette says in a childish, sing-song voice.
"Why? I don't even know you."
"That doesn't matter! I want to kiss you!"

Yvette purses her lips and makes a kissing sound. Uncertainty fills you, and you can't make up your mind whether to lean in or pull back. Then, she sticks out her tongue and runs it from one side of your lips to the other in one quick motion.

"Ew!" you shout, wiping your mouth. "What the hell was that for?"
"I just wanted to kiss you," Yvette pouts, crossing her arms. "Why couldn't I kiss you?"
"That's not how you kiss someone!"
"How do you know? Have you ever kissed anyone before?"
"Well... No. But my dad told me how."
"Your dad didn't tell you right, then," Yvette says with a giggle. "Let me show you... Turn around."
"Huh?"
"Turn. Around."

Something about Yvette's demeanor has changed. Her childishness has subsided, and been replaced with a predatory hunger. Her lips curl back, revealing her teeth, and her eyes are fixated on yours. She's like a predator stalking its prey, waiting for the right moment to strike.

You slowly turn around, facing the opposite direction. Before you have time to react, Yvette puts one hand on your chest and pushes you into the bed. The wind is knocked out of you as you lie there, struggling to get enough air into your lungs. Yvette climbs on top of you and puts her mouth to your ear.

"Is this how you kiss someone?" she asks, before nibbling on your earlobe.

You want to respond, but you're too focused on trying to breathe. Yvette takes your hand and presses it against her chest. You can feel her heart beating rapidly, almost as fast as yours. Her skin is ice cold, even colder than the IV tube that's still stuck in your arm.
Her pert breast satisfyingly fills your hand, and you feel her smiling as she nibbles your ear. The girl, still fully clothed, starts to undress you. She slowly takes off your shoes, socks, pants and shirt, until you're naked and exposed in front of her. She keeps her dress on and looks at your nude body with a smile.

"Anon..." Yvette says, voice brimming with anticipation. "Have you done this before?"
"N-no," you say, your own voice quivering.
"I want you to do whatever I say," Yvette whispers in your ear. "Okay?"
"OK..."
Yvette stands up, her dress clinging to her petite body, and takes two steps further up the bed. You're lying on your back directly beneath her now, and you can see that under her dress she isn't wearing any underwear. Holding her dress at the sides as if curtsying, she kneels down until her legs are either side of your head, and your mouth is level with her flower. Her scent fills your nostrils, and the warmth radiating from her core warms your face. You reach your hands up and hold her thighs, ready to pull her in if you can.
"Use your mouth, Anon," Yvette says, gently lowering herself onto your face.
You open your mouth and start to flick your tongue as Yvette grips the headboard behind you. She starts gently, rocking back and forth to ride your tongue. Her scent is almost overpowering, filling your nostrils and flooding your brain with her essence.

"Now," Yvette says, as she starts to move her hips. "Eat me, Anon."

You do as you're told, putting your hands around her thighs as you take your first taste. You explore her with your tongue, every flicker causing a jolt of movement from her stomach and pressing her groin against your mouth.
You're pretty sure Yvette is some kind of ghost or spirit, but right now you don't care. The way she's dominating you has you rock hard, and the scent of her pussy in your nose fills you with a primal urge to submit to her.
You use your tongue to explore her, trying to find the spots that cause the most reaction. She tastes earthy but sweet at the same time, and the wetness of it all has left your face dripping by now. Yvette starts rocking faster and faster, pressing down on your mouth as her breathing gets faster.
"Anon..." Yvette says, sounding pained. "Anon... I'm going to... I'm..."
Her words are cut off by a stifled moan, and she presses down hard on your face as her pussy tightens and convulses. She juices flood your mouth as she comes, and you lap it up as she slowly grinds her hips against you. She finally pulls away, a strand of spit joining your mouth to her pussy. She looks down at you, smiling.
"You did well," Yvette says, not moving from her position above you. "And now I'm going to enjoy teasing you to your own submissive orgasm."
You say nothing, but the reality that Yvette is in complete control over you right now is not lost on you. You're lying there, naked and exposed with a hard dick, and she's still fully clothed and holding all the power.
You reach your arms out for her, wanting to feel her skin against yours, but she slaps your hands away.
"Uh uh," she says, wagging her finger. "You will learn your place."
You're about to respond, but Yvette puts a hand over your mouth.
"Shh," she says. "No speaking. Not now. Unless I allow it."
Yvette slowly slides up your body, gently pressing her chest against your head before sliding out of reach again. She continues this pattern, sometimes gently running her fingers through your hair or brushing her knuckles against your scalp.
"Alright, I'll stop torturing you, you poor thing," she says with a smile. "I guess you were already pretty turned on from licking me out, so there's no need to tease you even more." Yvette settles in beside you on the bed, her petite breasts level with your face, and her hand lazily stroking your cock. "I think I'll make you cum this way, eventually. Maybe the sight of my cute body will burn itself into your mind?"
"Do you have to turn everything into a sexual innuendo?" you ask, as Yvette laughs.
"Of course!" she says.
You turn your attention to Yvette's toned stomach and small, but perky breasts. She's leaning over you, so they're the perfect size for you to suck on. You lean forward and take her right nipple in your mouth, gently sucking as her grip tightens on your dick.
"Mmmm, " she moans. "I can see I chose right with you."
You swirl your tongue around her nipple, and she presses your head closer to her. You take this as a positive sign, so you start to gently bite down on her nipple. Yvette squeals in pleasure as she quickens the pace of her strokes. You turn to her other breast and give it equal attention, taking the nipple into your mouth and flicking it with your tongue. She slowly strokes your member as you begin to lick her breast, running your tongue in circles before flicking it.
Yvette lets out a contented sigh, and begins to slowly pump your shaft. You're already ready to burst, and she's barely moved her hand at this point, but the slow upward motions of her fingers on your dick sends tingles of excitement through your body.
"By the way, Anon, have you figured out what I am yet?" asks Yvonne. "No," you respond. "Well, I'm more of a svelk than a succubus, but... let's just say the shadows are not exactly forthcoming about our history with our women.
"So you're half-human, half demon?" you ask.
"Basically," she responds. "But don't you worry, I've got plenty of succubus in me to make our time fun. I just don't have the... external parts to go with it."
"You seem to be doing okay for me so far."
"Mmmm, I'm just getting started," she says. "Now come on, more licking to be done."
As Yvette continues to gently rub your cock, you turn to her other breast and give it the attention it deserves. She smells nice, like some sort of perfume mixed with the smell of her skin.
You feel something thin but strong working its way under your back and realise Yvette has sprouted a spaded succubus tail, although the tip is shaped more like a heart than a spade. She continues pumping your cock steadily, gripping it tightly as if she owns it, and her tail prods experimentally at your rear entrance. You suck even harder on her nipple, and she murmurs in approval before pushing her tail inside you.
"Oh, yes," she moans. "This is what you want, what we both want. I can tell."
Her tail slides further into you, gently twisting and turning as it advances towards your vulnerable prostate. You keep suckling on her breast and she quickens the pace of her handjob slightly. There's a teasing note to her voice as she speaks: "Does my succubus tail feel good? Does it make you want to try something else? You want to try something... kinkier?"
"Oh, you have some kinky stuff in mind?" you ask.
"Mmmm, let's discuss it later," she says. "There's plenty of time for that. I can't wait to taste your seed."
You continue sucking on her teat as she continues fondling your genitals. She's offering a truly exquisite mixture of pleasure and pain, and you feel yourself on the edge of exploding. You try to delay it, to enjoy the moment for as long as you can, but it's just too much sensation for you to handle.
"I can't hold on any longer," you moan.
"Don't!" she giggles. "It's OK, you can let it all out. I want all of it. Give it to me!"
You groan as you feel your cum spurting out in strong bursts. Yvette pumps your member until you're totally spent, and then she slides into bed next to you.
"There," she says. "How does that make you feel?"
"Weird," you admit. "I'm not going to lie. But also good."
"That's good," she says. "So, did you like your birthday present?"
"I did," you say. "Thank you. You really are beautiful."
"I am, aren't I?" she giggles. "You're lucky I picked you. Now close your eyes, my little mortal, and get some rest. You've still got a long ways to go on your journey tomorrow.
You close your eyes and drift away to sleep snuggled up with your face in Yvette's small breasts, and barely notice that her tail is still inside you, very gently stroking your prostate and training you to submit to her...
