Sorry for being so inactive, I’m actually working on a graphic novel! Currently writing the novel part to be translated into graphic later on, which is taking up a lot of my free time. I hope you don’t mind this piece :’)
Fem!Reader, Full-blown rough NSFW. FILTHY! This is basically hentai in 2892 words lol
He grunts, eyes closed, irritated, tired.
Kasamatsu Yukio is a simple final-year university student: broken, battered, sleep-deprived, not knowing what the future holds. All boxes ticked. But if he is so tired, why has he found it super difficult to have a good night’s sleep these days? There is a lot of stirring in the middle of the night, but not to the point of fully awakening… He wonders if he should take some sleeping pills or something.
That is, until he meets the root of all his problems.
You.
He thinks it must be a dream, to have a girl hovering above his body on the bed. Especially when said girl has a pair of horns growing out of her temples, a long, thin tail, wings, and a tight… flattering bodysuit. With skin tight thigh-high boots—heaven knows how the hell a person can slip that on. The bare skin of your neck and shoulders, as well as the gap between your bodysuit and the boots does things to his heartbeat tempo.
Kasamatsu blushes. He knows he’s stressed out, but he does not expect it to be so pent-up that it manages to manifest itself into a dirty dream.
“A-Ah shit, you’re awake,” he hears you whisper, slightly panicked despite your dominant position over him. “Please go back to sleep.”
Your words do the opposite—he gains full consciousness, and though his eyes protest as they struggle to see in the dim light provided by his nightlight, he knows now that what he sees is real. Too real.
“You’re a dream demon,” he concludes. He’s heard of the existence of your kind through other people’s experiences, how rare they may be. To find one on top of him in the middle of the night is not something he expects.
“Y-Yes,” you reply, feeling a little bit called out. Your target is awake, and the best thing to do in this situation is flee and hope that he will remember this as a dream, but somehow his handsome blue-grey eyes bind you in place.
“…and you’re here to rape me?”
You let out a yelp.
“N-Not at all! We’re taking some of your life energy by… having sex… with humans as if it were an erotic dream, but we’re built for pleasure.” You utter the last part quietly, as if embarrassed. He suspects you are new to this. “The consent rate of our sexual act is 100%, I believe.”
“They are willing because of your pheromones, probably,” he comments, secretly pleased to see your flustered face. He is not lying, though. There’s a familiar sensation between his legs, a tingle just enough to spark more to come. He feels his blood rushing south at the sensation of you—he can blame it on your aphrodisiac-exuding skin or the smell of your pheromones or that damn thigh-high boots, even, but that does not change the fact that he is aroused.
“I-If you can just relax…” you begin, slowly leaning down to lick the shell of his ear. Electricity runs down his spine, and it has been a while since he last felt this horny. A thought stops him, and he brings his hands to your shoulder, pushing you away but not completely off his body.
“No, I can’t let you take away my life energy! I have morning classes!”
“I’m sorry!” You half-yell back, looking absolutely embarrassed for being interrupted, “I can’t afford to fail the test, I don’t want to repeat another whole year of training!”
That stops him and his train of thoughts. He never considered the possibility of relating to a demon.
“You need to pass an exam?”
“Yes. In order to become a full-fledged succubus, we have to successfully seduce an assigned human target in our practical exam night. This is my exam night. And I can’t change targets—it’s part of the evaluation for us to be able to seduce any kind of human…”
He pauses, knowing exactly what you mean. If you fail the test, you need to retake the training for a year… sounds a lot like university, to be honest, and he understands the pressure. The way his gaze softens at your troubled expression encourages you to plead further.
“I’m sorry that I have to take away your life energy,” you whisper, “but it will only be one night! I promise I’ll never come bother you again.”
Something tugs his heart at the prospect of not seeing you after tonight—he blames it on your aphrodisiac scent. Sure, he secretly thinks you’re fucking cute, but it’s not something you want to tell your one-night-stand partner, right? He curses under his breath.
“Fine,” he says, messing his hair up with his fingers in defeat, “do what you want.”
The surprised glimmer in your eyes makes his heart skip a beat. “Thank you!” You say, before your energy drops down. You slowly place your hands on his chest, and he admires the beautiful long fingernails playing with his pajama buttons.
“Then… I’m starting, okay? Please make yourself comfortable.”
You resume your ministrations on his left ear, and Kasamatsu hisses at the warmth of your tongue. There is still a hint of hesitance in your movements, but when he places his hands on the side of your thighs, snaking them up and down to feel the soft of your skin, you become more confident. Teasingly, you breathe against his earlobe, the cool air making his skin tingle after the sensation of your hot mouth.
“Relax, Yukio-kun,” you murmur, moving down to his neck. He wonders how you know his name—did whatever Succubus Academy provide you a file on him? With his name on it, the length of his dick, his secret porn searches? Kasamatsu finds himself pushing that thought away at the sensation of your teeth scraping lightly against his throat.
“I’m __________,” you offer, “you might want to keep that in mind.”
“__________,” he echoes, getting increasingly drunk on your sweet smell.
“Can we kiss?”
He nods, and you press your lips against his. Kasamatsu moans loudly, the sound muffled by your lips, soft and juicy and trained, judging by the way you nip at his bottom lip for permission. You definitely have no reason to be nervous about failing the exam.
Your tongue dances with his, leaving him slick with split, short for breath, and wanting more. You are lightly grinding your core against his hard-on, making him thrust up to meet your movements.
The buttons of his pajamas are swiftly undone, and your palms meet his toned chest. You feel your mouth water at the sight and touch of his torso, a natural biological reaction towards contact with a fine human specimen. Kasamatsu’s hand are slowly snaking up to your chest.
“You can touch me anywhere you want, Yukio-kun,” he nearly cums at the sound of your voice, somehow more velvety and lulling—he knows about succubi being built for sex, but not to this extent—but he somehow wills himself to hold on. A one-night-stand with a demon. Surely there’s going to be a lot of things about you that he can explore?
The two of you share a simultaneous moan, him because you have his nipple in your mouth, you because his hands just jerked the top of your bodysuit down, revealing your breasts. He gropes them unabashedly, relishing in the firm feeling of your tits being squeezed by his strong palms.
You journey south after playing with his nipples, now hard and pink. You impatiently take off his boxers by the hem, pleased to see that he’s hot and hard and leaking at the tip—as indicated by the wet spot on his underwear.
“Ahh, fuck!” He grunts when you take his tip in your mouth. Maybe it is the delirium induced by your scent, slowly infiltrating his lungs and breaking him from the inside, but your mouth feels heavenly, or in this case, devilish. You don’t waste any time teasing, partly because of his insistent hands in your hair, so you take all of him in your mouth, looking up at the man to gauge his reaction.
“Feels good,” Kasamatsu whispers, making eye contact with you. God, you look so sexy like that, how is he supposed to last? “Really good,” he emphasizes, grabbing a fistful of your hair and leading your movements up and down his cock. You don’t seem to mind his roughness—it is evidence that he’s telling the truth—and let out a muffled chuckle around his dick, the vibrations racking otherworldly sensations down his spine.
When your hand moves to play with his balls, he loses it. With a loud groan of your name, he throws his head back, gripping yours, basically face-fucking you to the point where his hot, white cum shoots inside your mouth into your throat. You welcome the spurts of semen as if it’s fine wine, his ejaculation rejuvenating you even more. You feel reborn, new, your eyes gleaming in the dark. You’ve passed the test.
But when you hover above him again, hair falling like curtain at the sides of your face, you see him looking back at you with the same unkindled fire. The crux of your thighs are sopping wet, even from the above of the bodysuit, and it calls you to do more. More. Put him inside of you, take everything he can offer.
“Thank you,” you cup his cheek, and he sighs. “You have morning class tomorrow, I don’t want to drain too much of your—nggg, ah~”
Kasamatsu pulls the apex of your bodysuit to the side, revealing your dripping cunt, and thrusts two fingers in, his thumb circling your clit. You moan, arching your back above him, but then he uses his other hand to flip you. With your back against the mattress, he kicks your knees further apart and leans down, adding his tongue into play.
You let out a high-pitched mewl, surprised at how dirty you sound. Kasamatsu finds motivation in your reactions and nips at your lower lips so fervently, eating you out like a man depraved. The urgency of his movements rival those of the rumored incubi, you think, running your fingers through his soft hair. Your pelvis rise and fall to the fast beat of his ministrations, only heard through the squelching of your juices meeting his tongue. You cum loudly when he decides to move up to your clit—he never stops his assault on the sensitive bud even after your own orgasm. His fingers collect them, and after he’s done licking you clean down there, he inserts all three fingers into his mouth, devouring your sweet essence like you did with his.
“An eye for an eye,” he murmurs, a dangerous expression on his face. And your file tells you that he’s supposed to be shy around women! “You’re overflowing,
__________.”
You’re eyes are still hazy and half-lidded when you reply, chest heaving, lips turning into a weak smirk. “And whose fault is that?”
Kasamatsu picks you up and you switch places, him sitting up against the pillows and you on his lap. He’s hard and ready, as if he didn’t cum a few minutes earlier. This man with be the death of you and of himself, you think—too much of his life energy and he’s going to be knocked out, literally. But your eyes see the opposite. He still have at least three orgasms in him. Kasamatsu Yukio is special. The fact alone makes you hungry, so much more than before.
“I’m going to fuck you,” you say, panting in heat, “is that okay?”
“Yeah,” he replies, watching as your eyes gleam a reddish pink. He didn’t think it possible to be more turned on than he is right now, but here he is.
“You’re going to miss your morning class,” you tell him. It’s that voice again, doing things to his body.
“Fuck morning class.”
In a split second, your bodysuit is gone, leaving you stark naked, except for the thigh-high boots, and ready for him. You sink yourself onto him gently, relishing in the sound of your moans mingling with his. He’s big, filling you up to the brim with his length, and you’re like a tight glove around his dick, hot and wet.
“Is this okay? Do you want it to be tighter?” You ask. He doesn’t respond, but then he lets out a yelp followed by a long “oh, yes” when you clench around him. Except you don’t unclench. One of the perks of having sex with a succubus, he thinks, is the otherworldly anatomical abilities you have.
You begin riding him, and Kasamatsu finds it difficult to decide if he wants to watch your bouncing boobs more or the place where the two of you are connected. He grunts with every thrust of his hip, determined to screw you senseless even with him bottoming. Then, he notices the tail swishing behind you.
Something inside him tells him to grab it, and he does, firm but not enough to hurt. He takes the spade-shaped tip into his mouth, thankful for the accommodating length, and sucks.
“Hyah! Oh, oh, n-not there, please, please!” you yelp, but contrary to your words, you only look more aroused, and if the brighter gleam of your irises means anything, it means that he’s doing the right thing. It doesn’t take the two of you long to reach another orgasm, thanks to your succubi features and him exploiting your weak point.
“Inside,” you pant, “cum inside me.” And he does. The rush of your love juices against his spurt of semen sends shivers and goosebumps down his spine, and he makes sure to give all of him to you, gripping your waist so tightly with his dick buried in you. The two of you watch with hazy eyes as some of the liquid leaks down your thigh, onto his leg and the bedsheets.
When Kasamatsu lifts you up and sits you on his stomach, it’s like a broken dam —your mixed cum forms a hot pool on his equally feverish skin, and he finds himself impossibly turned on. Perhaps there is more aphrodisiac in a dream demon’s love juice, he wonders as he scoops some of with his fingers and brings them to his mouth. Your lips fall open at the sight, and he takes it as an invitation. He does it again and let you suck on his fingers clean.
“You’re amazing,” he says. You feel his hardness against your ass and you let out a shaky breath.
“So are you,” you reply, offering him a shy, slightly coy smile. He hasn’t fucked you out of your shyness yet, it seems. It fuels his drive.
“Do you want to get an A? For your exam, I mean,” he asks.
“Yes, of course. Why?”
“Let’s do it again,” he says, and his normal self might be staring at him in disbelief if he ever say that so boldly, but his blood is pumping wildfire across his body, and there is only one way to alleviate it. “That way I’m sure you’re gonna pass with flying colors.”
“That’s very nice of you to offer, mmh,” you lean down to kiss him, tasting each other. Kasamatsu is the first to pull away, dragging you gently by the ankle to situate you at the edge of his bed, kneeling. You let out a weak, scandalous chuckle as he stands behind you, groping your arched butt. This position allows him to further explore you, particularly your wings…
“Your file failed to mention that you’re such a dirty boy.”
“No fun without surprises.”
And with that he thrusts into you again.
He ditched his morning class, but Kasamatsu remembers that there is a group work meeting in the late afternoon, which thankfully gives him enough time to get out of bed. You weren’t kidding when you said ‘taking his life energy’, he feels way more exhausted than he’s used to. His legs felt like jelly when he woke up earlier, and there’s a throbbing sensation in his nether regions that helps him remember the night before. Of course, you were already gone in the morning, but that does not stop him from recalling the… exciting things you did together.
Secretly, he hopes that you think it was as good of a night as he thinks it was.
Thinking about sex
is not the best thing to do
while walking down the crowded university hallway. His train of dirty recollections stop in its track when somebody bumps against his shoulders. He sees the person fumble next to him, but manage to regain their ground.
“Sorry!” A familiar voice says.
He looks back, only to see your face.
Your eyes aren’t pink, but a normal color, yet it still manages to drown him in. Your hair is style slightly differently, and the casual clothes you wear looks like it could hide a tight bodysuit underneath them. It is you, minus the horns and wings and tail.
“Are you okay?” Kasamatsu asks automatically. His mind is still processing.
“Yes,” you answer, offering him a small smile, “I had a… rough workout yesterday. Sorry.” There’s a knowing gleam in your eyes, but Kasamatsu registers it only after you leave, a good amount of distance down the hallway. It really is you.
You smile when you hear rushed footsteps behind you.
Funny and sexy! I LOVE confident Kasamatsu. Great job!!
