Marc grumbled and pressed his hand into the side of his head; he didn't think choosing University courses was going to be so difficult, but it would seem planning for one's future wasn't all that simple.
"Physics, chemistry, metallurgy... computer sciences... fuck."
He heard the front door open and shut.
"I'm home!" came Sophia's voice. Musical as ever, and it even seemed to buoy Marc's spirit.
"Whatcha doing?" she asked.
"Looking at uni subjects. And choosing none of them," he muttered in response, as he scrolled back to the top of the screen.
"I didn't figure you were thinking about going to uni so soon."
"Well, that talk we had the other day…"
"Like they say, it's more often who you know than what you know," Sophia added.
"Yep... though I suppose that's not a big deal for you," he mused.
She gave him a narrow look.
"What's that supposed to mean?" she asked pointedly.
In a moment, Marc felt the hairs on the back of his neck stand on end, adrenaline going through him as he panicked; did he just insult her real bad?
He was scrambling for an apology before Sophia mussed his hair and chuckled jokingly.
"I'm just messing with you, bro," she reassured.
He deflated a little, but gave her a moderately annoyed look.
"That was uncalled for, I thought I just put my foot in it," he complained.
"You kinda did," she confirmed. "But I can't really get mad about it because it's true. We do use our... talents to gain favourable outcomes for us, be it physical or supernatural."
Marc listened, and paused for a moment.
"I think so... there are still things bigger than charm magic, and getting involved in those things means you can't just boop someone's brain with a suggestion and expect to always get away unscathed," he said.
"Exactly," Sophia confirmed again, leaning in to 'boop' him on the nose, no doubt because of his choice of words. Her smirk confirmed it. "Otherwise, you have to coast along in the shadows off the work of others or things might go bad very suddenly. Or worse."
Marc saw her get a little serious with those last two words.
"What do you mean, 'worse'?"
Sophia seemed to stiffen a little, and then shook her head slowly.
"Nothing," she said.
Marc didn't accept that.
"I know that's bullshit, what is 'worse'?" He'd turned on his seat, facing her directly and staring her down.
Sophia sighed out, and sat down herself.
"I didn't really want to tell you this. But, I guess our history is something you should know. In times past... well, there were others that knew what we were. Not just our partners... and slaves, in some unfortunate cases."
She looked aside, as if telling Marc this was something she thought was shameful.
"Not all of us were the nicest sort. We kept to the shadows, succubi and incubi alike, for good reasons"
She paused again, tapping her fingers on the counter. Then she continued.
"You know how I said the morning after you found out I was a succubus that my mother said there were dedicated hunter Succubi and incubi, to deal with 'dangerous demons'? Well, that came about because others started doing that. Humans. And they found ways around our powers. Ways to resist, or to shield themselves, so they could get close and... 'exorcise the demons'. Usually with fire, or steel. Often both. We're not indestructible, just resilient. It really pushed us into the shadows further."
She sighed out, crossing her arms against the countertop and looking off into space.
Marc was similarly quiet, glancing down at his lap.
"I didn't know," he said quietly.
"I didn't want you to know," Sophia admitted. "I guess because I was worried."
"About what?"
"About how you'd react. Worried that there might be these people around now, out there, hunting us down. Or that you'd be in harms way yourself. You're my Soul Mate, Marc, that means I do care about you."
There was something weird about seeing her in such a state of... vulnerability? No, that wasn't quite right, but she seemed less confident, less herself.
Whilst Marc didn't like being lied to, it wasn't a lie. Just uncomfortable history someone didn't really want to share.
And there was something uplifting about her saying she cared about him so openly.
"Well, there's not any of these people around today, right?" he asked.
"Not that we know of. The world's a big place, but neither my mother or I have ever heard anything. Just the stories about our hunters, and I'm not sure how true they are either. But it's stuff I don't really like sharing because... look, I'll be honest, you are kinda cute when you're scared, that night was kinda... thrilling, when I saw your face. But I don't want you feeling genuinely afraid to be around me just because of what I am. That's not thrilling."
Whilst he wasn't sure how to feel about her finding him cute when scared, or the implication that they didn't mind a bit of fear 'in the moment', at least with Sophia, he did feel for her anxieties. His relationship with her was... bizarre, to say the least, especially knowing her proclivities. But as messed up as she was, she did seem to genuinely like and care for him. And he couldn't really complain, he was a bit messed up himself.
He reached out and held her shoulder gently.
"Hey, as long as no assholes come around here, I think we'll be fine. You haven't lied to me yet, right? I think I can keep trusting you just fine," he said, his turn to reassure her.
She turned to him and smiled softly.
"How do you know this isn't some extremely elaborate long con to steal your soul?" she said in jest, echoing old sentiments he had.
"Guess I don't, but I guess I'm a fool."
She chuckled, and she leaned in to peck him on the lips, a miniscule tingle of magic buzzing across them. He blushed, and then shook his head in embarrassment; she'd done all sorts of freaky stuff to him, and yet a small moment of affection from his Step Sister seemed to trigger his lingering reservations about being so intimate with a family member.
"Well..." he uttered.
"Don't tell me you're flustered over a little kiss now," Sophia teased with a small giggle. It was both a little annoying and somewhat heartening, she was back to being herself. Marc wasn't used to her being so serious.
"I suppose I'm still getting used to your idea of affection and intimacy," he admitted. He was quiet for a moment, and then rubbed his head. "How did we get here? We were talking about university courses."
"You said something that wasn't really offensive because it's pretty true, but also kinda rude to say casually," she reminded with a smirk. "And personally, I think we should both go to the same university. You wouldn't want to be deprived of me, now, would you?"
He gave her a lopsided look.
"I think if I can't go a while without fucking you, then I don't think I have a future regardless. Besides... wouldn't that be pretty risky? Or do you just want a new hunting ground and to keep me around?" he inquired with his own smirk, his turn to needle.
"I've never done college life. The amount of prey, the fun..." she let out a seething sigh of delight at the thought, closing her eyes, probably imagining it. "It'd be great~ Plus, who'd suspect the girl studying literature of being a soul-sucking slut from hell~?"
"Everyone, with the way you flaunt yourself," he muttered, prompting a giggle from his stepsister.
He was still somewhat... weirded out, by himself, when it came to how readily he accepted Sophia's nature, her lascivious attitudes and behaviours.
"True, but only you'd get to remember every delicious detail~"
"I am not fucking you in the kitchen, dad and Maria will be back soon," he chided rather casually, heading off any attempts at seduction.
She gave him a mock pout in response.
"Aww, you're no fun~"
He shook his head, but failed to stifle a small chuckle.
"I spoke to Chaney again," she revealed. "She asked about you."
Marc raised an eyebrow.
"Did she?"
"Yeah. I think she thinks you're cute, from what I felt skimming her mind~ You know, I can still hook you up with her, if you want~"
He felt flustered again.
"C'mon, you can't be serious. Actually, wait, you are serious. And I know what you said last time, about joining in. Isn't that a little too much?"
Sophia shrugged.
"Honestly, it's your call, but I wouldn't mind if you said yes. I won't lie, there's a bit of selfishness here; Chaney's cute, I'd love to hear her moan~"
"I'm surprised you haven't already."
"Hey, sometimes I hold myself back out of respect, she's a good friend."
"That makes me think you'd want to do it more."
"You'd be thinking right~"
He threw up his arms in defeat, turning back to his laptop.
"Sometimes, I can't get a read on you, Sophia," he admitted.
She slipped off her stool and hugged him from behind, pressing her breasts against his back and pecking him on the back of his head.
"I know, Marc~" Always teasing. She pulled back and grabbed her bag of clothes. "But if you want, drop in tonight, and I'll show you my newest purchases
---
After dinner, Marc quietly slipped into Sophia's room, though he really didn't need to sneak; Peter and Maria were again sharing wine in the living room, they were even watching a movie. A horror movie, of all things, but regardless, it meant they weren't exactly paying attention.
He knocked on Sophia's door, and quickly got an answer.
"Come in~" she sang quietly, and deviously.
He slipped inside, and she was on the bed with her phone, bags of clothes next to her. He could smell lavender with a hint of roses, perhaps her new perfume.
"You know you don't have to play coy~" she told him. "I knew you wanted to see me show off~"
"I'm being honest here, seeing you in sexy clothes? Not the worst thing in the world," he answered.
"Well, if it's just 'not the worst thing in the world', then your expectations must be grand!"
She laughed it off and bounced off the bed, gesturing for him to sit down. He did, and got himself comfortable.
"Well... guess the show starts?" he said.
She held out a finger.
"Not quite. We need to do this properly~ With surprise~"
There was a strange edge to her voice. And what did she mean by surprise?
She walked over to the door, and he saw the brief glow of runes as she cast her privacy spells, and then walked back to the centre of the room.
"Just sit back, and watch~"
Then she reached out, fingertips glowing as she drew more runes in the air. For a moment, Marc forgot his arousal or his eagerness to see his Stepsister in revealing, sexy clothing, fascinated by what he was seeing; for someone interested in getting into the sciences, he had found himself immersed in a world that defied them. Yet there seemed to be... mechanisms to what they did. Spells and enchantments seemed to have purpose, and elements behind them that made them work. It wasn't just them willing things to be. Maybe partly, but he was intrigued by the intricacies of how their magic worked.
About her kind in general. She was a huge demonic slut, he knew that much.
But it was kinda like encountering an alien, when he thought about it; she wasn't human, she operated on a different level. But she wasn't quite alien either, she existed alongside their world. Adapted as a predator with a very specific diet.
He was brought out of his analytical thinking when he suddenly saw Sophia obscured from view, as a blurry, shimmering veil appeared between him and her, Marc sitting up.
"Whoa," he uttered.
"It's nothing fancy, pretty much a magic privacy screen, simpler than what I do to keep hidden," she said, almost as if trying to lower his expectations. She certainly saw it with little fanfare.
He decided to put aside his fascination for now, he was supposed to be enjoying a fashion show.
From behind the blurry veil, he saw clothes being flicked to the other side of the room; short jeans, a pale green tank top, and some blue silk underwear.
He felt heat across his face; as many times as he'd seen her naked - hell, he'd eaten her out - he always got excited.
But there was something about the anticipation that was getting to him. She wasn't just stripping, she was stripping, but he couldn't see her. He knew she was stripping, she was there, in front of him, but obscured from view.
It was different.
Her hand slipped out from behind the veil, and waved in front of it, drawing it aside and revealing herself to Marc.
He let out a soft whistle of appreciation as she struck a sensual pose, running her hands down her torso and showing off some black, lacy lingerie, including a garterbelt and stockings, the Brassier's cut low enough he could just see the very tops of her areolae, where the discolouration began. The bra also seemed to push her breasts together, presenting rather deep cleavage to him that he couldn't quite tear his eyes off.
She ran her fingers down her body, and then up her thighs in sensual display when she straightened out. She wheeled slowly on the spot, fingers traipsing across the small of her back, whilst she kept her eyes on him over her shoulders whenever she could, twisting her body about, spine undulating not unlike a belly dancer's, just in slow motion, bringing her hands up her body and above her head before splaying them out in a sensual flourish, before turning around to face him, putting herself in another pose.
"What do you think~?" she asked, though the smirk on her face and the tone of her voice made it clear she was being rhetorical.
"What is there to say?" he admitted, a slight, mild-mannered complaint. "It's sexy."
She seemed amused, giggling softly.
"There's different ways to be sexy, you know~"
She gave him a devious wink, and with a hand, she pulled that veil back into existence like she was grabbing a curtain. He blinked a little, the magic screen a little hard to look at with the way it obscured and distorted and blurred. There were no clothes flung off to the sides this time, only a quiet pause, and then a hand once more appearing to reveal the devious fashion model behind.
Sophia was clad in white lingerie now. Lacy, but less elaborate than the previous set, and lacking stockings and a garterbelt. Still, it seemed to complement her tanned skin beautifully, and once more, she began to pose provocatively.
However, she did so in a more... shy manner, running her hands down her shoulders as she glanced at him from the corners of her eyes, shifting her head so strands of hair hung down, framing her face and her eyes.
She had a less salacious look, her smile warm and somewhat coy as she turned around, holding her arms close. Yet it was still a sensual display, hands still roaming her body, caressing her curves, and of course, showing off her new garments.
When she turned to face him again, she briefly covered up her bust as if shy to show it off, but let her hands slowly retreat with carefully choreographed motions so they trailed along her curves to bring attention to her brassier. It wasn't as tight as the previous bra, so her cleavage was a bit wider, giving the illusion of less depth compared to before... but no less appealing.
His cock throbbed.
"Wow... you weren't kidding," he said with appreciation.
"'Girl next door' vibes, right~?"
"Yeah, except you live in the same house."
"Your bedroom's next to mine, that's the next door. It counts~"
He chuckled softly at her devious logic, leaning back against the bed as he unzipped his jeans. He didn't pull out his shaft, he just wanted it a little more comfortable, not so constrained.
Her eyes glanced at his bulge, and he saw her mouth open a little in desire, licking her lips.
"Getting a bit hot and bothered there, huh~?" she teased.
"Soph, just move onto the next set of clothes," he murmured, though he couldn't hide the amusement in his voice.
She giggled in response, and again drew that veil back into view from who knew where.
Another wait full of anticipation, and then, he let out a small 'wow' when she revealed herself next.
She was wearing a high-cut leotard that pushed up her breasts and held them tight together, albeit with a hole just below the top with a deep opening right into the heart of her cleavage, another oval hole in the material showing off her midriff and navel, whilst her upper arms were clad in triangular sacasusa gloves, with her lower legs covered in leggings not dissimilar to the gloves.
The material was something akin to latex, or rubber, he wasn't sure, some dully shiny synthetic material coloured in a deep purple red, and it hugged and squeezed her curves beautifully.
The pose she took was more assertive, her grin more devious and sensual, even chuckling quietly as she bent down low, arching her spine sensually, flourishing her arms outwards before bringing them up her legs and up her belly, fingers walking along her skin and her garments. Once she was done, she struck a final pose, leaning to one side slightly, her stance wide but placing most of her weight on the leg on the same side she was leaning, hanging the arm that side down loosely against her thigh, whilst the other braced on her jutting hip in a sensual but assertive pose.
She blew him a kiss.
"Where the hell did you get that?" he asked. The other clothes, pricey, but he figured some of the upmarket clothing stores could provide. He had no idea where one would go to get something so... salacious.
"That's a secret~" she teased with a wink and a giggle, though Marc wasn't all that worried. "You know, I don't have to ask your thoughts on this one, I can really feel what you're thinking~"
"It's crazy... but hot," he said. "Like, you've got femme fatale vibes this time."
"I like to think of myself a bit of a 'femme fatale' at times~ Just with a little less of the 'fatale'~ It's more fun~"
"I like less 'fatale' myself, thank you very much," he said in jest. "Got any more?"
"Why~? You want to see your stepsis in every sexy getup you can think of~?" she teased, pushing her bust out a little to taunt him.
"I didn't think of that," he retorted, pointing to her garb. "But, can't lie, it's fucking hot seeing you do that."
She cast him a sympathetic but lusty smile.
"Alas, that's all I bought. And you've seen pretty much everything else I've got, so... I think you know what happens next~"
She bit her lower lip, and he could see her eyes alternating between looking at his face, and his crotch.
He knew that she was fond of him, but Marc honestly wondered how much Sophia simultaneously saw him as a prize cut of meat. Her hunger always felt so... literal. Well, it was literal, she was quite literally feeding off him. But a more... primal hunger, more predatory. He was literally soul-food for her.
He didn't resent her for it, it was just... another level of fascination for him, thinking about the way she thought. How her brain ticked. The human elements, and the not-quite-so-human qualities.
He didn't linger long on this when she stepped forward, leaning in to cup his bulge in her hand, fondling it softly and making him let out a quiet moan.
"You must have been churning away, watching all that~ Got a nice big load for me, bro~? A lot of energy for me to sip~?"
She pushed and grabbed his junk a bit more firmly, digging her fingers in a bit more.
Marc rocked his head back, torso arching a little from her provocative groping.
"All there waiting for you," he panted out. Just what she wanted to hear, Sophia grinning hungrily and licking her lips.
She fished her fingers beneath his underpants, hooking her fingers around his erection directly, and giving it a few slow strokes.
A spot of moisture appeared on his grey undies, precum dribbling from his tip through the material.
Even still moderately constrained within his underwear, her touch was tantalising to his cock, and a shiver raced up his spine. She pumped a few times before extricating her hand, and bringing both to the sides of his jeans so she could slowly peel them off his legs.
Naked from the waist down, Marc shivered from the mild chill, but his cock seemed to be radiating warmth as it stood at attention. Sophia eyed his girth desirously, and crouched in front of him, hands gliding along his thighs until they converged on his junk, one hand wrapping around his mast and pumping slowly, the other grasping his balls and subjecting them to a sensual massage.
"I think you're getting bigger, Marc~" she said.
He tried very hard not to react to strongly to that. Even he didn't seem above the desire for a big cock, and Sophia seemed like the kind of girl who didn't mind large sizes. Fuck, she was probably adapted to taking any size.
"Really?" is all he dared say. He didn't want to give her too much ammo for teasing. But one word seemed enough for her.
"Does that excite the big strong man inside of you~?" she said with somewhat mocking tones, but she giggled, and leaned in to peck his glans with a soft, tingling kiss, drawing a sigh from Marc's lips.
"Shut up," he muttered, face flushed with an even deeper shade of red. "You're the one who said it."
"Well, maybe it is~ It feels so... nice... so... firm~"
She accentuated her words with slow, tighter strokes of her hand, intensely stimulating even in the simplicity of a handjob.
"Fuck..." he groaned. Another giggle from Sophia, loosening her grip and stroking a bit faster, constantly fondling his balls with circular motions.
She applied a twist to her pumping, repeatedly peeling his foreskin back over his glans, and down again, and occasionally rolling her palm over his tip to smear that precum all over.
He was again appreciative of her trimming his bush, which he now maintained; it felt... better. Nothing could possibly get caught, the hair didn't cushion any touch, she could really get down to the root. Things moved even smoother than they did before, and he no longer felt that annoying, pervasive 'wetness' from moisture being trapped in his pubes. Everything felt slick, and it all glistened from his precum as she slowly lathered it into his skin.
He could already feel a pressure building in his loins. Knowing her, she probably wasn't going to stop and move onto something else, she liked pushing him over the edge using every method. Foreplay wasn't just the foreplay, it was another tool in her arsenal, another way for her to feed and tantalise her prey. In this case... him.
He gripped the sheets, a pant loosing from his mouth as her hands rolled and glided across his junk, balls fondled, cock stroked, and every motion exquisite and smooth.
She splayed her middle and index finger apart, and slipped his length between them, Sophia stroking him with those two digits, and twisting them to his glans, before wrapping her hand around his girth properly once again. She gained even more speed, the sound of her efforts slick and perverse.
"S-Sophia, I'm close," he warned huskily.
She started stroking faster in response.
"Don't hold back, Marc~ Cum for me~" It was a sensual command, a little domineering even. It fit her attire, and he wondered if maybe she was acting the part because of her clothes.
He was, however, not in a position to ignore her; Sophia's efforts were masterful.
A few more moments, and he let out a moan, and he bucked into Sophia's hands.
The white ropes fountained into the air and down onto her hands, still stroking, wringing him out.
"That's it~" she crooned. "Let it all out~"
He thought he pumped a good four or five ropes before he started sputtering and dribbling, and then stopped entirely, Sophia easing her efforts and letting go, something Marc was grateful for; he wasn't sure he could really contend with her inflicting post-orgasm torture.
Still, he groaned in lingering sensitivity, the stimulation caused by her wringing her hand up his length to gather any residue that did not fall on her hands, bringing them to her mouth so she could make a show of lapping up his white stuff with a slow, voracious eroticism.
He spied a soft glow across her lips, and it spread slowly, subtly, across her forearms, and once it passed, he only saw a light glistening from her saliva.
She never did leave him for long without a reminder of her inhumanity, but he was starting to grow enamoured with it.
"Tasty as always~" she praised, reaching forward to press a fingertip to the frenulum of his cock. He winced in sensitive reflex.
"Glad to hear it," he murmured. He wasn't soft yet, and he knew Sophia wasn't going to be done with just that.
As if to confirm that, she grinned and shuffled forward, reaching around behind him to tug him closer to the bed.
"Come on, stand up~ I have a real treat~"
He blinked, a bit quizzical, but he didn't argue, getting to his feet. His eyes widened the moment Sophia positioned herself so her breasts were right in front of his shaft, grasping his length and aligning it with the hole in her leathery leotard, leading right into her cleavage.
This was... new. He'd seen it a few times, mostly in hentai, only a handful of times in real world porn.
"You want to...?" he began, but she shook her head teasingly.
"No, I want you to~" she corrected, rubbing his sensitive glans to the edge of her cleavage between the hole in her garb teasingly. With the way it compressed her bust, even if it pushed it up a little... he was sure he could get a bit of depth, though his dick might end up angling a little. It didn't matter, her tits felt incredible, and having that leotard keeping them nicely squeezed... he was sure it was going to be a different feeling.
She was looking up at him, seductively, eagerly, encouraging him to take the lead, resting her hands enticingly over the tops of her bust now, letting go of his cock so he could take charge.
He wasn't sure he was completely in charge, but it was his pace to set. So he grasped his cock, aligned it with her cleavage hole... and with a soft moan, pushed inside, gripping onto one of her shoulders for leverage with his free hand.
She bit her lower lip and glanced up at him expectantly, every expression carefully tailored to get him more riled up. And she was a pro at it. As expected; it was instinct to her.
He was still a little slick from his climax and her delightful handjob, but she made sure to add to the lubrication, opening her mouth and letting her tongue loll out. She drooled saliva down into her cleavage, and then giggled once she provided her dose, watching him with a lusty smile as he began to move back and forth.
Damn, she felt good. The leotard was compressing her globes tightly together, so all he really had to focus on was moving his hips.
She was so warm, but sure enough, his glans hit her sternum, causing it to slip up a little along her body, but with how slick his glans was, and how her saliva seemingly worked its way down between her tightly squeezing breasts, it was still a slick motion, and it gave him about an inch extra motion before he began to pull back.
He kept his helm trapped between her tits, allowing him to grasp her other shoulder... and start thrusting slowly, a soft sigh leaving him.
Sophia murmured appreciatively, seductively, keeping her hands to herself so he could lose himself to the stimulation entirely on his own terms, and his own desires.
He couldn't thrust too far, her breasts weren't that big compared to doing it lengthways, but he was feeling good all the same with the range of motion he had.
"Fuck, this is hot," he huffed, looking down, and ever so occasionally spying his tip through Sophia's cleavage from the top, buried deep down betwixt her bosom.
"Isn't it~?" she said smoothly. "Fucking your stepsister's perky tits in this getup~ Feels so sinful, doesn't it~?"
"If I say 'amen', will you laugh at me?" he joked in response.
"Unholy is just another sort of holy, no~?"
He was surprised how much he was getting into Sophia's style of dirty talk; she wanted him to be corrupted, in a sense. It was still a sort of play, but her desire to see him get more and more depraved in these sessions was clear to him.
He started moving faster, stimulating himself pleasantly, but it wasn't quite enough to push him over the edge. He wasn't disappointed, it still felt good... but Sophia had designs to change that.
He felt a spark race through him... and luminous eddies form around her breasts, and his crotch.
He could see the currents, see them swirling down his length, drawn into her bust, see how the swirls curled up and out from the top of her cleavage, into her body, though plenty of whorls sank into her globes.
He felt like he was being sucked into her breasts, the tugging in his core drawing him in as her drain took hold.
She gave him a salacious, predatory look, but it was far too sexy for him to care. He knew he was safe. And her drain was a most welcome 'cheat'.
His cock buzzed with pleasure, the tantalising pressure from her breasts now even more stimulating as every point of skin-to-skin contact was a direct, tantalising drain that lit up the point of contact with pleasure... which was to say, most of his cock. And where there was no contact, he still felt a wonderful thrumming tingle as every nerve was caressed with tantalising pleasure.
Pressure was again building in his loins; it wasn't the strongest drain, hardly, but it wasn't all that light either, just enough that it, combined with his thrusting, would see him to a climax.
He picked up speed, enough he could hear the slick sounds of his cock repeatedly sliding in and out of her enveloping breasts, which now felt like they had a dangerous attraction.
She opened her mouth momentarily, unfurling her tongue; vapours of his energy wafted up from the depths of her cleavage and the tops of her breasts, a provocative, obscene display as the eddies coalesced into a singular spiralling column that calmly siphoned into her mouth.
Sophia closed her mouth with a small puff of the misty light, but she'd shown off enough for him, licking her lips with a hungry, seductive gleam in her eyes.
That just encouraged Marc to move faster.
And that bit of extra speed was all that was needed to push him over the edge.
"Fuck!" was the only warning Sophia got, verbally at least, before he was jerking his hips with sharp movements, cock pulsing and pouring cum into the dark depths between her breasts, spiritual barriers coming down and a helical pulse of light coalescing around his groin and racing down his shaft to be devoured by her breasts. She moaned erotically, closing her eyes and tilting her head back slightly, feeling the pleasure of his climax.
Her drain vanished quickly once he finished cumming, the misty veils around them dissipating, Sophia not wanting to exhaust him just yet.
Once he calmed, Marc slowly pulled out, taken by the sight of his sticky cock sliding free of her squeezing breasts with gooey strands of his essence stretching and sagging between his rod and the edges of her ravenous cleavage.
Sophia grinned and licked her lips subtly at him.
"You made a mess in there~"
"That I did~" he answered with a breathier voice, just a little tired from her drain.
She giggled, and used her upper arms to squeeze her bust even tighter together. There was another glow, brighter this time, and when it faded, only a film of moisture remained. She shuddered, and a tiny wave of weariness passed her face. It passed quickly, and she fixed him with a lusty gaze.
"Got one more in you~?"
"I think I've always got a third round for you," he said with modicum of suave.
"Good~" She stood up and pushed him down onto the bed, pulling his legs up onto it and climbing atop of him, straddling his thighs.
He was a bit taken aback, but he did not resist, instead moving to take his shirt off so he was fully naked.
Comparatively, she remained fully clothed, and yet she remained sexy as fuck.
He reached up, and ran his hands along her sides, feeling her leotard beneath his palm and fingers; it was a smooth material, not much friction, but a little stretchy, with the way it flexed whenever she twisted and bent.
He also just wanted to touch her. It made her smile too, a soft, affectionate giggle leaving her. He liked that. She seemed to enjoy it when he explored her body. In a way, it proved to him that he wasn't just special food to her.
She reached for his junk, trailing fingers tantalisingly across his girth, making it throb in response, already, another dribble of precum leaving his tip, which she wiped up with a fingertip to bring to her lips, tongue tasting him in yet another sensual display.
Then she gripped his shoulders properly, and slid up a little until he felt that shaft sandwiched between his belly and her leotard covered pussy. She rocked her hips slowly, grinding against his cock in a stimulating manner.
"I wonder, will you be upset if you don't get to stick it in tonight~?" she asked with a devious, teasing tone, an expression to match twisting her face.
"Now that's just mean," he retorted, though there was hardly any venom in it; as much as he wouldlike to bury himself in her pussy, or ass, the way she did things, combined with her drain... it was almost as good, and more than satisfying enough for him.
It certainly satisfied her too.
She rubbed slowly, though periodically, she lifted away to run her hand around his length with a few pumps, smearing precum and saliva from her mouth around his cock, lathering it in and keeping it lubricated and the friction within pleasurable levels.
Sophia was playing with him with the dress she bought, that much became clear to Marc. With lubrication, the smooth, stretchy synthetic material of the leotard provided a unique rubbing touch, gliding smoothly across his sandwiched dick. He could even feel her labia through the material, forming a shallow groove his manhood slotted into, the channel grinding from root to tip with each fluid roll of her hips, her body undulating sensuously.
Sometimes she twisted side to side, keeping the stimulation fresh, whilst keeping his eyes constantly fed with a lurid show of her hypnotic movements.
He couldn't keep himself from sliding his hands up her body, touching her, feeling the material of her dress beneath his palms, until he cupped her breasts, fondling them gently with soft moans resulting from her grinding.
She sighed out, but smiled seductively at him, sliding her hands up his arms from his shoulders, caressing them until she gently gripped his wrists, lightly pulling his hands a bit more firmly against her breasts as she continued to grind.
He almost wanted to call her a slut, in a dirty talk sort of way, but he found his tongue caught just by how good she looked doing that, touching him, silently insisting he grope her more firmly.
He wondered if he was getting even more depraved, or if she was quietly twisting up his brain with her succubus influence.
She started moving faster now, and slipped her hands back down to his shoulders, over them, and brought them up his neck to cup his cheeks, looking down into his eyes.
Hers started to glow red, and he felt her drain reignite. But it was much stronger than this time, for sure the finale tonight.
Their auras formed, currents swirling and twisting away from his body, absorbed into her luminous veil, wisps of pale light curling off his dick as it was ground beneath her covered pussy, like his penis was smoking.
The vaporous light curling off him was always surreal; it was his life energy. He could feel that weariness affecting him already. He was literally watching the essence that kept him alive drawn out of his body. Sophia even said that her kind could kill if they drained too much.
It kinda scared him once, but now he felt a certain thrill to it, especially given how good it felt, and that Sophia, for all her insatiability, had never once hurt him. He'd rest, feel a bit groggier than he used to in the morning, and be fine.
He groaned in pleasure, a large surge of precum leaking out onto his gut. Her drain was everywhere, he could feel the pleasurable buzz in her palms and fingers against his cheeks, watching currents of his energy drawn into her hands and swirling up her gloved arms. And he could hardly tear his eyes of hers, those deep red orbs gaining slitted pupils. She didn't usually gain the more demonic traits, but they often glowed when she drained him.
Still, it reminded him of that first night they had sex properly, when he first learned what she was. They had a sinister edge to them, but Marc no longer found them so frightening. Oddly beautiful.
It was getting harder to think, her drain, and the pleasure that came with it, eroding his spiritual barriers and his faculties respectively.
"I'm... fuck... close..." he muttered through panting breaths.
"Don't hold back~ Don't resist~ Cum for me~"
That dress must have put her in an unusual mood; whilst no dominatrix, she had a calm, commanding demeanour that he found exquisite, which rather befitted the fact they had only performed outercourse this night.
The drain made it feel all that more intense and tantalisingly.
"I... I... fuck!"
He couldn't hold out any longer, and with a loud moan, he bucked up against her grinding hips, and shot out his ropes across his body, his belly, and his chest.
He even felt a splatter hit the bottom of his chin, but he was not in a state of mind to be repulsed, moaning loudly, and finding his jaw unable to close; hers opened, a glow formed in the back of his mouth, and he let out a quiet wheezing sound when he felt another tugging current wind its way up from his core, up his throat and out of his mouth, siphoned all the way into her waiting maw.
The intense, orgasmic pleasure prolonged his climax, starting to become almost unbearable. She kept this up, a little while, giving him an open mouth smirk.
And then, her drain started to fade, and the veils began to dissipate, the final eddies swirling into her skin. She closed her mouth with a satisfied murmur, licking her lips.
He went slack, panting with exhaustion, trying to straighten out his brain. He felt Sophia's hands leave his face, and then, she draped her body atop of his, breasts squashing against his chest, as she gently caressed his chin with the fingertips of one gloved hand.
"Thank you for the meal~" she said, in a tone that was both teasing and affectionate.
"You're... welcome..." he managed between breaths. He groaned and sank a bit against the bed. "You didn't... cum?"
She leaned to one side a bit so she could peck him on the cheek, eliciting a light groan from him as a spark tantalised his skin.
"Oh, I was so close to giving up and joining you, bro~" she said. "But I just felt like holding back, I wanted to... I don't know, I guess I wanted to feel powerful? Commanding? It felt so good~"
"I... noticed. You were a little... different. Not a different person, different, but... calmer. Not more dominant, but... dominant in a more reserved way... words are hard, okay?"
She chuckled warmly, and gently tilted his head so she could run her tongue up his chin, lapping up the spurt of his cum that managed to splatter against his lower jaw. It made him shiver, a shaky gasp leaving him.
"It's these clothes," she admitted once she was looking at him again. "They just made me feel... really nice~"
"Isn't that why girls buy clothes anyways?"
She giggled, and buried her face into the crook of his neck affectionately, though even that wouldn't be without a lustful edge to it, slowly drawing her tongue up his throat until she was kissing him on the lips gently, the tingles of her lighter drains making him shiver again.
She broke the kiss and smiled.
"I really enjoyed tonight~" she said. "I've dressed up nice for people before, done stripteases, but you... you get to remember~ And it's not just for my own fun to tease my prey, I wanted you to enjoy it too~ Like, on a deeper level."
"What deeper level, I didn't get to stick it in," he joked, prompting Sophia to playfully thump his shoulder, chuckling.
"Next time, bro~" she said, before nuzzling into his neck with a contented sigh.
He smiled and laughed as he relaxed, feeling like he was going to go to sleep soon. But as he laid there, feeling Sophia gently wrap her arms around him to cuddle, he thought back to the start of the encounter; watching her cast the privacy spell, summoning that veil. And further, her drains... and those demonic red eyes of hers, staring into his soul.
He couldn't help thinking about them, but he wasn't unsettled. He was mesmerised, and as he slowly felt his eyelids growing heavy, he couldn't shake off that curiosity that'd been growing for a while, but had strengthened the past day.
---
It was a quiet day, and Marc - once he'd had about two coffees in the morning and some real fatty bacon to recover - took the opportunity to do some research.
It was a lot of nonsense, and a lot of hentai, that he had to filter through, but he found various documents, and literature, about succubi and incubi. There wasn't all that much to go on that was unique, having to avoid fictional representations in fanwriting and other media. Of course, historical documentation about sex demons was going to be pretty limited, focusing more on the mythological aspect, the various tales and fables from older days. Including one story about a succubus that tried to seduce a pope, but eventually helped him because he remained stalwart.
He didn't expect to find much truth, Sophia told him how much they kept to the shadows. Even those old, wicked demons that enslaved or murdered people, did their best to hide their actual nature. They probably gave rise to the superstition, or amplified it, but kept a lot of their truths a secret.
However, after a while, he found a few small accounts supposedly about Succubi and Incubi plaguing towns and villages, or sometimes individuals. He didn't get the sense of much truth to them, though it'd be impossible to know. The superstitions had a real source, but they spread into the various fables or false accounts he'd read.
Or were they false? How much was truth and how much wasn't was impossible to know, but he wasn't frustrated by this; after all, he had a primary source he could ask any time.
It was more a curiosity of how Sophia's kind had influenced people, in some way or another, and how there were those that tried to live less destructively in order to avoid incurring the wrath of humans, despite their parasitic, destructive nature.
It was rather fascinating, really. And he was surprised in himself, too, he'd never really been fascinated in any one subject enough to devote free time to this much, admittedly casual, research.
He was in the middle of reading a historical account from some medieval scholar who seemed terrified that a succubus was visiting him every night when Marc heard a knock on the door.
"It's me, Marc," called Sophia.
"It's open, come in," he invited, and he heard Sophia slip inside. A week or so ago, and he might've felt a little awkward about her coming into his room. Well, he still did at times, because of how she got, but it wasn't nearly as uncomfortable as it was.
"I haven't seen you all day. I was hoping you'd like to watch a movie or something... whatcha looking at?" she asked, peering over his shoulder.
"Succubus stuff," he answered. "Or whatever I can find that's at least written historically."
"You know 99 percent of that stuff is bullshit, right?"
"Of course I do, but it's... insight. Gives me an idea about how they thought about your kind back then," he said.
"None of it's positive," she summarised without missing a beat, crossing her arms casually.
"I didn't expect it to," he agree. "But still, succubi, incubi, they left a mark on history that hasn't really gone away."
She was quiet for a moment, looking at him with a tilted head.
"What's with this sudden interest in my people?" she inquired. "You've always asked questions, but this is a little different."
He paused as he turned on his chair to face her, looking for the right words.
"Well, crazy as it is, I think I'm starting to get... well, used to you," he revealed. "As 'used' to you as anyone could expect. It still freaks me out a little from time to time, how crazy it all is, but... now I'm just curious. The way you do things, how you do things. Not just the sex or the sluttery, I have an okay idea about that part. But, like, the magic stuff; the spells. All of it."
He sighed out, trying to get to the crux of his intrigue without sounding like a jackass.
"I don't mean this in a... nasty way," he began. "But you're not human. But, like, that's the part that's got me fascinated. You're a literal demon, that's crazy. But, I don't feel constantly tired or in pain or feel like your slave. So... I guess I just want to know."
He waited, worried he might've said something wrong, but she just smiled warmly.
"You don't have to walk on eggshells, Marc," she said. "I know I'm not human, I don't take that as an insult. I'm a succubus, a demon, I feed off the life energy of humans, I have instincts that drive me to hunt through sex. Not kill, mind you, and not just to feed. We are sexually voracious creatures, we enjoy fucking. That's not quite human behaviour. Besides, I'd be able to tell if you were telling me these things with hateful, fearful or otherwise prejudiced intent behind them." She tapped her head to remind him of her powers.
"But that's just another thing, you can read minds. Or, well, emotions. Skim thoughts, I think you said. You can do all these things, but the way you explain it seems like there's more to it."
She gave him a look, he wasn't sure what it was. Perhaps curious herself? In him? She sat down on the bed, Marc not failing to notice her bust bouncing, just a little. She was in casual clothes again, but that really didn't stop him from admiring her. He really was screwed.
"Stronger succubi and incubi can directly read thoughts without much effort. Mum can do it with a bit of focus, but someone like me, I'd have to charm someone first, wrap them around my finger magically, then I'd be able to read their thoughts without much issue, if I didn't just have them spill all their dirty little secrets to me on a whim."
Marc still found some aspects of Sophia's nature and thus others like her a bit frightening, how they could easily subjugate a human if they wanted to.
Sophia hadn't done much to him besides that one sleep charm the first time he discovered her true form, just to help him sleep. But she asked him to trust her. Nevertheless, a part of him was still disconcerted by the fact she was acting purely out of manners and integrity. Which wasn't the most comforting thing for a 'weak' human like him.
His thoughts must have been picked up by her, because she cast him a focused look.
"You're still scared of me. A part of you at least."
He almost panicked, worried he'd upset her, looking for an excuse, even denial, but she gave him a sympathetic look.
"I don't exactly know what you're thinking, but I can't blame you for being a little afraid of me. Meeting a being that could so easily beat you into submission without even touching you. Look, I told you that I thought you were cute when you were frightened, but I also said it's different when it's an 'in the moment, oh my god what the fuck holy shit' kind of fear," she explained, pantomiming with her hands towards the end. "Dread and despair, that's not my thing. It was definitely the thing of a few, that's why we were hunted. That's why we supposedly have hunters of our own. People were scared of us, from what mum told me. They weren't wrong to be afraid. They weren't wrong to find ways to fight back. But not all of us were monsters. Hungry, and carefree, sure, but that's what we are now. Feeding on people, blowing their minds, then altering their memories so they only have wet dreams, and taking only so much to not hurt them. We were hunted all the same, because these people didn't know us. We lived in the shadows, hiding what we did for safety, but... turns out that was a double-edged sword."
She sighed out, looking down and sombre. Marc almost felt uneasy when she looked down, it wasn't normal, it wasn't the flirty, constantly teasing stepsister he'd come to know.
"Being this powerful has its downsides. That's what mum told me. You can't help yourself, it makes us feel so good. But if you get found out, you're going to frighten people, terrify them, in a way that charms and glamours aren't going to suppress. Because then you're not even known about, just known of. A scary threat. People who can muster the courage and find ways to protect themselves will act, and they inherently don't trust us, so they won't give us the benefit of the doubt or listen to our side of the story, and hunt us down until we're dead."
Marc took this information in; he really didn't see it that way, and suddenly he realised what a big deal it was for her to be this... open with him.
"I had no idea you were taking such a big risk that night," he said.
"To be fair, that was an accident, I lost control of my form, probably because it was my first time with you. Soul Mate, remember. But no lie, I wanted to, when I felt you might've been more receptive. But things happened, and I just went with it; no use panicking, you know," she explained.
Marc was quiet again, and then gave her an apologetic look.
"Sorry for bringing this stuff up. I was just wanting to talk about your kind, like how your magic worked and shit, I didn't want to bring up sensitive topics."
"Nah, it's fine, Marc. This stuff, it is our history. It is about us, it's stuff you'd want to know if you want to know more about us. For the record, it's... nice that you ask. I was more than happy for you to be just interested in my body, or the sex, though being into my personality was a win, but being interested in the history of my kind? It's nice."
She gave him one of her rare, truly genuine smiles, and it made him feel a bit warm.
"Just that natural human curiosity, like if someone met an alien that was friendly," he remarked.
"An alien with a sexy body and an insatiable appetite for dick?" she retorted deviously, squashing her bust together with her upper arms and poking the tip of her tongue out past her lips whilst giving him a devious look. So much for her genuine smile, but he was starting to see her constant lascivious acts as oddly endearing.
"You know what I mean," he said, sarcastically shaking his head as he turned back to his computer. "Though, I didn't learn all that much about your magic."
"That... might have to be another time," she said, sounding uncertain herself. "Trying to explain complex magics that comes to you semi-instinctively to someone who doesn't have magic or that knowledge is... hard. Because there's rules and things involved that even I don't understand, becauseit comes to us so naturally."
He turned back around to her with a raised brow.
"That complex, huh?"
She shrugged with a 'I dunno' look.
"It's like... imagine rocket science, except you've evolved to just have it in you instinctively, but when you go to do... rocket science stuff, you still gotta think about what you're doing, even the complex stuff, but even that comes to you naturally. You gotta be taught, you gotta learn some things, but it's more... feel. But at the same time, there's strict rules and laws, or things don't work. You know?"
The look she was giving him was a little scrunched, and entirely lacking confidence. Not often did she come across as 'dumb'.
But it did sufficiently explain to Marc that it wasn't easy for her to explain these things.
"Like trying to describe colours to a person born blind," he added.
"Maybe not that hard, but yeah, let's go with that," she agreed with a point of her finger.
"Well, next time, I guess, but I am interested in learning, especially all that rune stuff."
She let out a slightly jokey sigh of exasperation.
"That'd be even harder, some of those letters in the runes even mum doesn't know. I try not to think about it, myself."
Marc could understand; who knew what spells she used that could turn disastrous because she used something wrong because she didn't understand.
After a moment, he decided he wouldn't think hard on it either.
"Fair point," he conceded.
"But," she continued, getting off Marc's bed and draping herself over him from behind, wrapping her arms around him in a loose hug. Her breasts were pushing against the nape of his neck as her cheek brushed against his hair on one side of his head. Marc felt a little heat in his face. "I will try my best."
"Thanks," he said, ever so slightly shaky. She giggled sweetly, and angled her head down.
"Free tonight~?" she asked with a gentle but mildly seductive tone.
"Yeah. I think I can go again tonight," he answered, smiling softly himself.
She murmured happily in response.
"Looking forward, bro~" With that, she pecked him on the top of his head, and pulled away, hands sliding sensually off him as she parted. She sauntered to the door, and lingered in the threshold to blow him a kiss.
He blushed but smiled, and turned back to the computer once the door closed.
"Same," he said to himself as he went back to looking up "legitimate" historical accounts about succubi and incubi.
Though, as he looked at an old religious depiction of a succubus, a generic classical depiction of a nude woman, but with bat wings, other thoughts started filtering into his mind... particularly, remembering what Sophia looked like that first night together...
---
It was almost routine at this point, a nice family dinner, a hearty conversation, and then sneaking off into Sophia's room, though this time he had to actually be a little careful, because Peter and Maria were busy doing some household stuff and they were going back and forth between upstairs and downstairs, even though it was getting on in the night.
Sophia was waiting for him, reclining on her own desk chair inside, looking at him with a seductive expression. She was wearing one of her gowns again, simple, but sensual, loosely hanging from her shoulders and barely concealing anything with its near transparency, and her lack of underwear.
"I've already cast the privacy spells~" she said with a grin. "No need to wait on my account~"
"I don't mind... it's kinda fun, leading into it," he said as he sat down on the edge of her bed, just idly noticing out of the corner of his eye a dull pulse of light move across the width of the door not long after he closed it.
"That's actually nice to hear... some people don't seem to appreciate a nice build up~" She rose from her chair with a sultry jut of her hips, whilst Marc reclined against his arms atop the bed. "So... what shall we do tonight~?"
She strut forward, letting her dress slip across one of her arms, giving him a brief glimpse against her bare pussy.
She cast him another look, a small devious chortle leaving her, before she loped gracefully and straddled his hips sensuously, wrapping her arms around his back loosely, her bare sex resting against his growing bulge, her thinly clad breasts pushing against his chest.
"Maybe I can show you a few of my other clothes~ Or play with the other two from last night~"
"Actually..." he began, somewhat embarrassed about what he was going to suggest. "I was wondering... if it's not dangerous or offensive or anything... if you'd try your true form."
She was quiet for a moment, regarding him with a neutral look. Then she smiled, a deep, salacious look, but she was utterly silent.
She gently pushed him down, and she guided his legs onto the bed until he was laying on it properly.
She still straddled him, hand against his chest, before she sat up, and made a slow, sensual show of disrobing herself, letting her gown slide down her arm onto the floor.
Then, she leaned back, tilting her head upwards and running her hands up her body, catching her breasts and letting them bounce down when she stretched her arms above her head.
She let out a sigh. Then she started to glow.
He blinked his eyes, finding it hard to focus on her, like his vision was going blurry. But it was just her that was out of focus, further obscured by her luminescence. However, shapes formed from her back, her waist, her head, growing out from her... and when she came back into focus, red glowing eyes regarded him, lips pursed into a thin, devious smile.
She had her horns, her wings, her flexible tail. Her ears were pointy again. Though a detail he did not notice the first time, her skin seemed to darken, just slightly, except with a subtle red hue, giving her a reddish-brown complexion.
She lowered her arms and rested her hands on his shoulders. He noticed also that her nails seemed to have grown sharper. Still incredibly neat and glossy, but they seemed almost clawlike now.
All in all, she had this air of danger about her. Forbidden, treacherous, predatory. She was a demon.
She was beautiful.
"How do I look~?" she asked him with a rhetorical tone and a sensual flick of her long hair.
"Incredible," was all Marc could answer with. Last time he saw her like this, he freaked out bad; Sophia scared the hell out of him, even if she was coy about it.
But now that he was getting used to her, getting interested in this side of her... he could actually appreciate the demonic beauty she possessed; she had inhuman features, sure, but nothing was grotesque, nothing was truly unsettling.
If anything, it made the whole 'forbidden temptation' thing more believable.
He reached up, and slid his hand up her smooth belly, across her midriff, until she took a hold of his wrist in one hand, and delicately guided him further up to her bust, Marc taking one of her breasts in hand and giving it a gentle squeeze.
He then spied something; a thin, happy smile on her lips.
She seemed to notice where his eyes went.
"I've shown people this before. But they're always in a glamour, charmed. They don't remember it. I do it for my own enjoyment. You have no idea how it feels to be able to be... myself, really. With someone who'll remember. Who wants to see me like this. That's special to me. This is special to me."
"You're not getting sappy on me now, are you?" he teased. Her answer was to gently dig her nails into his chest, making him wince whilst her smile turned dangerous, though he could see no malice in her.
"Let me enjoy this, Marc~"
He managed a nervous laugh, her sharp grip more than enough to get him to concede the point. But he did feel happy for her. It did seem special to her, and he was glad for it. Plus, he was a bit excited to see how things might be different.
"So, what can you do in this form?" he inquired, and she shot him a knowing, devious look.
"Let me show you~" she purred, sliding over his bulge and leaving a trail of warm moisture behind. That was something else he was starting to notice, she felt warmer than usual. Not uncomfortably so, quite the opposite, but it was like there was a flame inside her, perhaps some of that demonic hellfire biblical literature liked to harp on about.
As she slid up, he watched her wings flex behind and around her, their slow movements making barely audible stretching sounds as muscles and membranes flexed, some light shining through them, just barely.
She came to rest on his midriff, and he couldn't help sliding his other hand up the side of her body, caressing her; she was so damn warm to the touch. Especially her hands, running them sensually up his arms as he felt her, smiling and murmuring appreciatively towards his touch.
"You're hot... literally, you're so warm," he commented, he just couldn't not say it aloud.
"Demon~" she answered simply, sighing out again as she gently ground her hips against him in idle arousal. He was satisfied with that answer as he slid his hand around to her back, sliding up... and feeling around the roots of her wings.
They were leathery, but a little rough, tough, firm muscle beneath firm hide. Still, she seemed to shiver at the touch, a little murmur leaving her.
"Hey, I was the one supposed to be showing you~" she reminded him... and before he could answer, he felt something slip beneath his pants, and his underwear, and start worming about against his junk.
It was his turn to murmur, feeling the touch of a smooth, soft, leathery shape trying to wrap around his imprisoned erection. It slipped further, and he felt the flat side slide around his balls, massaging them gently.
He groaned, and looked around her, and saw her tail flexing and buried in his pants.
"That's.. new," he remarked. Her tail was much smoother, softer, more delicate compared to the roots of her wings. It was incredibly precise too, able to flex and bend tightly and with incredible control, akin to a tentacle.
So it came as no surprise when she was able to unzip his pants and pull down both them and his underwear past his hips to let his cock spring free.
And immediately, it coiled around his girth, root to tip, like a snake, the tip wrapping about his balls and fondling them in a soft, dry, but sensual hold.
"I hope you're not freaked out~" she said, sounding both sympathetic and entirely devious.
"After that thing you did with your tongue the other day, no... damn, that feels surprising," he murmured.
"You'd love what else I could do... but I'd hate to get all the surprises out in one night~" Her chuckle was wicked, and yet Marc couldn't get enough of it.
"Don't mind that~"
"Good~" Her tail began to stroke up and down his girth, sinuous lengths sliding delicately all around his shaft with a spirally grip.
It was like a handjob, but at the same time not; the coils stroked at different speeds sometimes, and they expanded and contracted up and down, so the pressure and points of contact were even more changeable than a hand.
The diamond tip kept up its massage of his balls, however, constantly swirling about the jewels in their sack, slowly juggling them, tugging and stroking his scrotum, never allowing for an idle moment.
It also meant her other hands were free to do with as she desired, sliding them beneath his shirt and pulling it off, seeing no resistance from him.
Now with his shirt gone, Sophia was free to rake those sharp nails across his chest, applying enough pressure to leave thin, fading welts in their wake. It made his chest jump, his diaphragm flinch at the acute touch, and a small gasp leave his lips.
"You're not... gonna tear my heart out, are you?" he asked only half jokingly.
"There's a joke I could make right now, but I don't want to ruin the fun~ Just that right now, you're myprey... human~"
She cackled softly, and he gasped again as she 'drew' random shapes into his skin with her nails. The way she called him 'human'... it got to him. Not in a negative way. A thrilling way. She was getting into it, a demonic femme fatale that had him where she wanted. Her wings beat slowly, and he felt a gentle wave of heat wash over him.
But it didn't take long for her drain to ignite. Weak, but tantalising, her veil forming but mostly noticeable around her hips, and behind her. Sophia raised herself up so he could see for himself, watching her stroking, twisting, coiling tail coat itself in an aura of luminance. He could see vaporous energy starting to spiral up his length, whirling into her flexing appendage and twisting up its length into her spine. He noticed the glowing parts of her horns get a little brighter, as did her eyes.
Precum began to bead from his tip with a small, meek little buck from his hips. And the succubus quickly capitalised on this, rubbing a loop of her tail over his glans and smearing his pre into the skin of his dick and the soft, smooth hide of her tail, allowing her to move that little bit faster. He groaned, and then watched her drop down onto his chest again, obscuring the view but certainly not cutting the sensation.
"There is not a part of my body I couldn't drain you with, Marc~" she explained to him with a salacious tone. "I could hug you, and drain you so hard you wouldn't be able to stop cumming~"
"Don't... threaten me with a good time," he retorted half-jokingly again, trying not to be completelysubmissive.
"Aren't I already~?" She giggled, and then slipped forward until she was sitting on his chest, grabbing his wrists and holding them away from her body.
"I want to feel good too~" She raised her hips over his face, and he watched mesmerised as her sopping pussy hovered into view, dripping warm, sweet-smelling arousal onto his cheek.
She usually smelled good, but her aroma now seemed... different. Enticing, but otherworldly, he really had no other way to describe it.
She gyrated her hips a little, circling her pussy above his face for a few long moments, teasing him with what was to come, before she dropped down onto his face, slow, but inexorable.
He reached up and clutched her thighs for leverage, though he didn't start just yet, feeling Sophia rock her vulva against his lips for a few moments before parting them to let his tongue forth to do its job. He was still modestly inexperienced in eating pussy, but her previous instruction hadn't left his mind, and he was sure he was going to gain a lot of experience with her.
Up and down, his tongue started to loll and curl, tasting her unnaturally sweet fluids, a constant trickle onto his lips, his tongue, and into his mouth, tantalising him further.
He tilted his head slightly so he could start working at her clitoris, rolling the tip of his tongue around the bud, sliding up between it and the hood, trying to get into the folds and gently work his jaw away at the area. He was still nowhere near confident enough to try and apply teeth, he didn't want to accidentally bite her there.
It didn't seem like a deal-breaker, given the way she moaned so sweetly, rolling her hips firmly against his mouth as she ground against him. Marc could feel how her thighs and her glutes squashed and rubbed against the different parts of his head with each direction her pelvis tilted, a wonderful rubbing all around him as he ate her out.
Her tail started stroking faster, and her drain intensified just a tiny bit, helping to push him towards his first climax of the night.
He moaned into her pussy, and she seemed to like that, biting her lower lip and groaning lowly, alluringly.
She looked down at him, those red eyes looking brighter than the light of the room. Of course, she always had hers dimmed during these moments, so it definitely made the glow more noticeable, more enthralling.
He worked his way back down her vulva, probing his tongue against her entrance and trying to keep her clit stimulated with gentle rubbing from his nose, though he wasn't too accurate. Still, Sophia reached down to caress his brow, encouraging his efforts, so he had no reason to stop trying.
He was getting closer to orgasm, feeling that pressure build. It pushed him to waggle his tongue harder between her nether petals, pushing his muscle into her passage.
That's when her drain gained a second front, and he was unable to suppress a moan strong enough, even Sophia couldn't help moaning sweetly with him from the vibrations he caused.
He saw her belly glow. Not with some stereotypical 'womb tattoo' or 'succubus stamp', whatever they liked to call them. No, just a dull glow from within, as she pulled energy from him slowly. He saw the wisps curling out of his face out of the peripheries of his vision. He shuddered from the new source of stimulation, but kept going. He wanted to make her feel good too.
His hands slid up from her thighs, to her hips, and around until he had firm holds of her glutes, squeezing and spreading that bubbly butt to his heart's content, prompting more moans and gasps from Sophia, which only further encouraged him.
Her tail was stroking faster now, using every bit of lubrication from his dick it could get, and he provided a lot. Enough that, with its current pace, Sophia's tail starting making a barely audible, slick sound. Not one inch of his cock was spared a firm caress from the flexible appendage, rolling and pumping relentlessly. He was so close now.
And the whole time, she kept looking at him, a lustful, hungry smile on her face as she rocked atop his. Every now and then, her wings beat slowly, sending a wave of low heat throughout the room. He didn't recall her being this warm the first time. Maybe since she wasn't as riled up. Maybe because he was about ready to piss himself in fear and mistrust.
Now he couldn't stop noticing her.
He couldn't ignore the pleasure his cock was feeling either, and not just her drain; the tail was still as alien-feeling as ever, the only thing similar being her 'tonguejob'. But whilst her tongue was slick and squishy, her tail was thicker, soft and smooth but not as malleable. It was almost as flexible, and the extra friction offset by his leaking tip made for a slightly different, and just as exotic, sensation.
It was only natural that he was cumming before long, moaning loud into her pussy and jerking his hips in orgasm, each small buck upwards sending ropes of semen into the air, some smattering against her tail, most falling down onto his crotch or his gut.
Her thighs clenched around his head, and she let out a long, low and utterly salacious moan, shivering and spattering juices against his lips and into his mouth. He clutched her hips tight and rode out the orgasm until she calmed down.
Her drains eased and faded, and her tail started to loosen up around his cock. She sighed out, and then rocked her hips back so he could breathe properly again.
"You're getting better, bro~" she praised, running her fingers through his hair.
"T-Thanks," he said, a little out of breath. He was recovering readily enough, but orgasms with Sophia were always a bit tiring, especially when her drains were involved; the feeling of his spiritual barriers falling and the surge of energy that came with it was never not a bit of a rush.
"But I hope you've got your breath back, because I'm not quite done with you down there~"
"Wait, wha—mff!" His inquiry was cut off when she rolled her pussy back atop his mouth, though immediately she began to deftly manoeuvre, twisting around atop his face until she was facing the opposite direction and his face was obscured by her ass.
He felt her shift, cheeks and thighs rubbing against him as she laid herself down atop his body, gliding fingertips tantalisingly up his sides until they came to rest against his thighs. A soft breath left her lips, and he felt warm, tingly air blow across his slightly moist glans, residue from his lathered pre and ejaculation cooling it a bit even despite the warmth of her breath.
Of course, the intended effect was to excite, and his still-erect cock bobbed eagerly. Also eager, Marc, who started once again licking and lapping at her pussy, seeing how things were different now that it was reversed for him. His hands once more reached up to grip her cheeks, sinking his fingers into their pliant mass, fondling, groping, squeezing that perfect ass.
He started to push his tongue in between her walls, trying to go deep this time, and was rewarded with an even stronger taste, a delightful flavour that wanted him to go deeper. Talk about a honey trap.
Her moans came with soft, tingly breaths across his glans, but Sophia wasn't just content to blow teasingly across his cock. She angled her head, and he felt her soft lips press to his tip, and slip down across his glans, Sophia suckling his tip gently, tongue rolling against the slope and against the slit at the apex. Her suckling was like a kiss, slowly bobbing against his helm, not taking him deeper just yet... and imparting a light, teasing drain, gentle tingling arcing across his tip, still a little sensitive from the prior orgasm. It made him buck a little, but he composed himself... as best one could whilst in the middle of a sixty-nine with a sex demon.
She slurped every now and then, the sounds reaching him, albeit muffled, through her thighs and ass, a more forceful suction against his tip, until she started taking more of him into her mouth, completely without hands, both still gripping his thighs. Her hands shifted, sliding and wrapping around the backs of his thighs and gripping them on the inside, about halfway to his knees, her sharp, demonic nails teasingly scratching at his skin.
A few moments more, and she started going lower, gently reciprocating her head, twisting her lips about his girth as she descended, until Sophia was kissing his root.
He gasped into her pussy, but pushed himself to go a little harder, working his jaw away at her mound, though he still tried not to use his teeth much.
He waggled his tongue faster, pulling back occasionally to lap it up and down the whole of her gash, sometimes wriggling it firmly against her clit since he couldn't easily latch onto it now. He was no match for her, of course, but he didn't mind the inferiority; she was supernaturally evolved for sex. He was still making her moan.
And her moans thrummed around his cock as she started bobbing from root to tip, twisting her lips but never once breaking the seal, save for when her tongue peeked out past her bottom lip, curling either way in its constant licking efforts... until, one moment, when her lips were at the base of his cock, her tongue wrapped around the root... and stayed there, even as her lips retreated, all the way to his glans.
Her tongue kept curling, wrapping around his base in a tight, slippery grip. Her lips came back down, sliding over her muscle without a hint of pause, keeping up her pace even as her tongue started to kink and twist so it could coil around his girth, squeezing tightly, and after a few more root-to-tip bobs of her head, began to twist and pump on its own... independent of her fellatio.
Her tongue even slithered further down to slide and curl around his balls, tugging on them, fondling them, rolling about the spheres in their sack, polishing them with a layer of warm saliva.
Suffice to say, Marc faltered a little in his efforts. She still had a drain up, but it was honestly not nearly as erotic and alien as the feeling of her tongue wrapped about the majority of his shaft, a flat length of her muscle in her mouth pressing against the slope of his glans, whilst her lips continued to move and twist with the bobbing and reciprocating motions of her head, sliding over her squirming, wriggling tongue constantly. It was sloppy, and yet it still felt like her lips kept the seal against his skin as best as she could manage.
It was honestly absurd how incredible it felt.
If he didn't have a mouth full of pussy, he probably would've been swearing into the air. Instead, he was giving her vulva a good dose of vibrations from his lusting moaning. He shuddered, groaned, curled his toes, did his best not to dig his own fingertips too firmly into her glutes lest he hurt her on accident, but already a pressure was building again in his crotch.
Her rolling moans and the thrumming of her lips and tongue against his cock as a result did not help him hold out.
He started tapping her rump in warning, trying to tell her that he was about to blow, starting to jerk and shake a bit beneath her.
It was pointless, she always knew when he was going to orgasm, and it didn't matter if he was deep in her throat when he did, Sophia would take it, gladly.
As if to further tease him, he heard muffled chuckling, which only made things more tantalising when he felt the muscles in her throat ripple from the laughter right against his glans. It was an intense sensation, and it was enough to push him over the edge.
As expected, Sophia did not slip off his cock, instead pushing her lips down against his crotch and drinking his surge with lurid glee.
He bucked upwards with each rope he loosed, moaning right against her pussy; an eye for an eye, since that seemed to set her off too, though now both were moaning in euphoria, sending vibrations directly into the genitals of their partner.
Fluid gushed across Marc's mouth, and he did his best to drink down the sweet fluids. His head spun, the aroma was bizarre but enthralling, making him moan even louder.
All this as they felt the surge of pleasure that came with the extra rush of energy whenever he came, also amplified whenever she came and she lost a bit of control over her drain. Not enough to be dangerous, but enough that it could easily prolong their climaxes for quite a few moments more.
But, she wasn't draining him too hard, so they eventually calmed down, Marc panting against Sophia's pussy with heated breaths, whilst she groaned in lewd satisfaction as she slid off his cock, tongue trailing along it in retreat and making him moan some more.
Finally, she lifted off his face, and he got his first clear breath since they started, gasping a little and taking the opportunity to compose himself.
He saw her stretch a little, a sensual display that excited him even during his recovery period.
He propped himself up on his shoulders, and watched her cleaning her lips of any residue he might've left behind.
"That was... crazy hot," he remarked. "Really fucking hot."
She turned her head, those red orbs catching his attention all too easily. She smirked.
"Can't get enough of your slutty stepsister's sexy succubus sloppy-toppy~?" she answered back.
His face cracked a bit. A snort escaped his nose.
"Wow, that was terrible," he teased. She giggled, and then twisted around to crawl towards him.
"Always for you, bro~ I'm such a terrible influence on you~" she crooned seductively, crawling over him and cupping his cheek in her palm. "Always making you fall into sin... how very terrible of me~"
For a moment, he was a bit cowed, taken by the sultry, predatory demeanour in which she approached, and the tone of her voice, so dripping with devious allure that they held no small amount of sway and appeal.
Of course, he wasn't completely enthralled, cracking a smile.
"Your dirty talk is as cringey as ever," he teased.
"Yet it turns you on~" she whispered softly, leaning in to peck him on the lips, only her sweet taste gracing him. An arc of tingling pleasure spread across his lips before she pulled away, a tiny wisp curling up from between them.
"I hate that you're right," he muttered, though he still had a smile on his face.
She giggled and leaned in to whisper into his ear.
"You attempting to be 'cool' turns me on~"
She licked at his earlobe, and a shivering sigh left him.
Another giggle, and she pulled back, sitting down and sandwiching his cock between his gut and the cleft of her cheeks and her labia, gently rocking and grinding upon his mast to invigorate him for the final round.
"You want to stick it in, don't you, bro~?" she murmured softly, voice dripping with lascivious delight. "You want to feel my tight succubus pussy in all its glory, wrapping around your cock all nice and wet~"
She walked her fingers along his chest, gently but pointedly digging her nails in so he felt it sharply, until she stopped to ever so delicately trace a circle against the pinkish disc surrounding one of his nipples, making him arch his back and gasp.
"Y-Yes..." he answered truthfully. It was kinda pathetic, the way he sounded in response to Sophia's usual style of dirty talk, but he couldn't help it, feeling her grinding her vulva and the bottom of her rump against his erection after two exquisite orgasms and his own twisted excitement over fucking her in her demonic form all rather encouraging him to give in.
She smirked, her hand trailing up his body and curling fingertips up off his chin, earning another shiver.
"It's nice when you're honest, Marc~"
She lifted herself up in a way that let his cock slide against her vulva, until she was able to seat herself on it like she was balancing on a pinnacle, even though her calves pressed to his sides. She circled her hips a few times, her usual teasing, twisting rubs that stirred his cock to get him full of excitement and anticipation.
Both of her hands found a pectoral to splay against, bracing herself on his chest.
Before she even began to drop down, he felt her tantalising drain arc across his glans, getting her siphon going early. And then, she dropped down slowly.
She felt a bit different this time.
He hadn't noticed that night. Maybe because she changed mid-fuck, maybe because he was scared out of his mind, maybe because she wasn't actually different and he just thought she was.
But she still felt different to him. Familiar, if one could get familiar with the feel of a pussy around one's cock. But her folds, her textures, they felt... sharper. More defined. He couldn't quite explain it, but they gripped him extra firmly, yet still exquisitely.
"Oh... damn..." he breathed out as she sank down, making little twisting rocks of her hips, bending his mast side to side luxuriously, all the way to his hilt.
She came to rest on his crotch, and a seething sigh left her lips. There was a different quality to it. It sounded much more like a hiss. Just subtly inhuman.
She started rolling her hips again, grinding once more and pushing her folds firmly into all sides of his girth, grinding in every direction.
He fucking loved it when she did this, he got to feel that bubbly ass of hers squish and rub against his groin, it really got him going.
After his bout of submissiveness, he began to explore her body again, running his hands along her flexing frame, reaching up to grope her breasts, and Sophia was more than happy to let him, luxuriously sliding her own hands seductively up his arms with encouraging caresses, biting her lower lip.
Sophia, however, decided to up the stakes relatively soon enough, and began her bouncing upon his mast.
It made him wince in pleasure, feeling how much more intensely her pussy seemed to scour his cock, especially his glans. And with her drain keeping everything nice and sensitive, she seemed even more intense.
Soft, musical pants of euphoria began to leave her lips, lewd but enticing as she rode him. Every now and then, she'd return to her grinding gyrations, ceasing her bouncing before resuming, or she'd blend the two stimuli together, and she alternated between those lusty pants or luxurious, erotic moans.
Marc couldn't do much more than groan and swear.
"Holy... fuck..." he exclaimed.
Even as she rose and fell atop him, the smacking of their impacting bodies filling the room, only shrouded from the rest of the house by an intangible veil of magic, she kept her eyes on him and laughed teasingly, but pleasantly.
"I figured you'd know by now these fucks aren't holy~" she retorted.
He managed a shaky chuckle.
"I think... you've made that joke before."
"And I'll probably make it again if you keep making cute sounds like that~"
Her wings fluttered, buffeting him with warm air, her tail flicking about behind her, before it curled down and started ever so carefully rubbing his balls, making sure their light jiggling didn't accidentally smack them painfully against her leathery appendage. It didn't take much.
Nevertheless, it made a breath hitch in his throat as she reminded him of her demonic qualities.
It encouraged the pressure building once more in his loins... but it seemed Sophia wasn't just content to ride him to the finish. She had designs.
He was in the middle of an eyes-closed moan of pleasure when he felt an unusual touch around the sides of his body, slipping beneath his back. He opened his eyes and looked side to side to see her wings reaching down and sliding beneath him, the bones within proving to be deceptively sturdy, the thin musculature of the wings belying its strength as he was pulled slowly into a seated position.
It was different from her hands, but not unlike her tail, smooth, surprisingly plush hide wrapping around him, not as rough as their roots, though it was a different feeling altogether due to the thin, warm membranes stretched between rigid bones wrapped in slightly rougher hide.
He was thoroughly taken aback though, looking around as he was hugged by her wings, held tight against her still bouncing body, breasts squashing and rubbing against his chest.
"What are you..." he began, but she silenced him with a finger to his lips, slowing down for a moment. Her other hand snaked up beneath her wings, and then both gently cupped his cheeks.
"Just look into my eyes, Marc~" she asked soothingly. "Do you trust me~?"
He contemplated for a moment, this was rather sudden. A little different.
He thought back to the last time she asked him that. He was a lot more hesitant then.
He wasn't this time.
"Yes."
She smiled, and then pulled him into a firm kiss, tongue slipping into his mouth to dance with his.
Her tail wrapped around his waist, locking him close with Sophia, much as her wings did.
And then everything started to burn with pleasure.
He moaned loudly as their auras formed. He choked a little as a current of energy started funnelling its way up into his throat, and then out into her mouth. Another started roiling out of his cock into her pussy.
And all over, he felt her siphon drawing energy right out of his skin into her wrapped wings, into her body, her arms, her tail, everywhere. Her eyes shone bright, her horns glowed and it seemed her body possessed a subtle inner luminescence now.
Then she started bouncing at full speed again.
He wanted to scream into her mouth, the stimulation was that intense, that amazing. His eyes rolled into the back of his head as he just barely had the mind to wrap his arms tight around her waist, clinging to her for dear life.
The slapping of her rump against his thighs echoed up from down below and between her wrapped wings. Spirals of energy roiled off him erratically, absorbed by her aura. Her pussy squeezed rhythmically around his manhood, and her muscles flexed in such a way doing so that it felt like there was a physical suction beyond the tugging sensation of her euphoric energy drain.
His tongue tried hopelessly to dance and swirl with hers, but it was shaking constantly from his laboured moans.
It didn't help that even her tongue seemed to be siphoning energy from him, delving into the stream that poured up his gullet when it slithered into his throat, but there was no gag reflex at all, it'd been thoroughly suppressed by her drain.
Her lips meshed intimately, but assertively, with his, sweet murmurs issuing into his mouth as Sophia revelled in the pleasure she too felt.
He was starting to lose his damn mind, it felt that good, possibly almost as intense as that one time she sent him over the edge with a kiss, though this had so many more sources of stimuli at once, all contributing to pleasure all throughout his body.
He wasn't trying to play a role anymore, now simply trying to keep sane.
She started to move faster now, that moist slapping filling his ears as well as her murmurs gaining a higher pitch. She was close, he could feel it in the quivering of her walls.
He was certainly closer, he could feel his orgasm boiling in his depths, ready to release, the lustful fire stoked to uncontrollable levels, though he was simply along for the ride now.
Did she do this with other people? If she did, then memory alteration was surely a necessity, not just because they'd surely remember something so intense, but because of how it'd probably half-fry their brain for the next day if they remembered.
He would only be partially fried afterwards, his only real resistance to her drain after experiencing it so many times already.
And he was never going to forget. This was special.
Even still, it felt like he was getting swept up in the current, and if he didn't hold on, he'd be lost to it.
He'd already lost his willpower. Just a few more moments...
Marc practically screamed into her mouth, the ecstasy just that wonderful, little erratic jerks of his hips as he poured his final load for the night, and it would seem the biggest, into her depths.
His barriers shattered, his energy came surging forth into her body, Sophia's aura glowing brightly as whirlwinds of energy were pulled out of him.
She followed suite, though unlike his cry of ecstasy, her moan, as loud and as intense as it was, had a decidedly more musical, delighted tone to it, even as she began to spasm all around him, her wings and tail squeezing even more tightly around him, her pussy closing like a salacious clamp despite its convulsions; he was trapped with nowhere to go, and she was going to feed on every vapour of his life she could safely extract from him.
The climax seemed to go on forever, his eyes started to water even.
And then, like a switch was flipped, her drain vanished in a snap, and her tail and wings slackened suddenly. She released his lips with a gasp, one last rope of his energy whipping into her mouth before she smacked her lips closed and licked them in savouring delight.
He went limp in her embrace, and he felt like was about to pass out, panting softly as his mind was blank, his face slack-jawed and his eyes almost glazed over.
Sophia then chuckled sweetly, and pecked him on the cheek, a spark of pleasant stimulation spreading through his skin.
This seemed to reset his brain, Marc blinking a few times and then gasping shakily as he looked at her.
"Good... fucking... god..." he exclaimed weakly.
She didn't tease him for his choice of words, simply hugging him close and murmuring sweetly into his ear.
"I'd thought I'd really show you what it was like fucking me in this form~" she said with a devious but warm grin. She was oddly good at that, mixing affection with her wicked lust.
"Do... other guys... get this treatment?" he said with an incredulous tone, not at all accusatory of course. He couldn't sound so if he tried with how exhausted he was.
"Rarely," she answered. "I rarely show my true form to other humans, always under a glamour so they don't really realise. And going that hard is rarer still. They're not Soul Mates like you are. That'd put them out for half a day. I do it when I'm feeling really predatory. You though... I think you know why~"
He managed a thin smile.
"I'm your Soul Mate Step Bro," he said, letting out a hard breath that was supposed to be a laugh.
She smiled and pecked him on the lips, Marc shivering from another small spark of her drain, a dull wisp of energy curling off in between her luscious petals.
"You wanted to see me as a demon. You found me beautiful like this. I mean, we're not hideous like this, hardly. But still... it feels good to be open with someone you're close to~ Someone who appreciates who you are~"
"You're... making me... blush."
"I like teasing you Marc. Just because it's my nature doesn't mean it's not genuine."
"That was... teasing?"
"Oh, do you want me to call you a dirty boy that gets his jollies off fucking his sister~?"
He chuckled and pushed against her.
"It's... more you," he teased back.
"Mmm, guess you do know me~ And appreciate me~"
She sighed out and leaned against him, hugging him, tail and wings still loosely and affectionately wrapped around him.
He held onto her and rested his head on her shoulder.
He thought about what she said; not too long ago, he would've questioned if he really appreciated her. He was still unsure of this arrangement. Now though... if not a typical romantic relationship, he was sure now that she meant every word. Their relationship would never be normal. She was his stepsister, and a succubus. She didn't think quite the same way.
But if this was what amounted to love for her, Marc felt content with that. It was strange that he was content, but he'd started to embrace the strange.
Maybe going to the same college with her was a good idea... it'd be thrilling, if nothing else.
