My Succubus Family Ch. 04

CHAPTER 4: CONFESSIONS & REVELATIONS

The nightmare was always the same.

He was in the clearing again. It was a beautiful place. The lake's waters were still and calm, the dense woods behind him betrayed no sound. It could have been a pleasant dream had it not been for the horror before him. Elana and Rose were dead. Their vacant eyes bore into his soul. Yui was on her knees, sobbing uncontrollably. He tried to speak but no words of comfort came. Instead came a guttural, demonic voice from within.

'....... our fault'

Yui looked at him with rage and sorrow etched across her beautiful, terrible face.

'My... daughters.... son.......-cent........ exchange...... that...... al.'

He laughed cruelly.

'change..... mind-'

The dream stuttered again. He was still talking but his voice was distant. The dream was collapsing around him. He tried to wake up but something soothed him back to dreamless sleep.

Isaac woke up with the alarm. He felt mentally drained, a recurring occurrence since the nightmare began. For three weeks, he had been trapped in that same nightmare every night. It always ended in that same exact moment. For a few minutes, he contemplated. He was always speaking with Yui, but the words were fragmented and incoherent. Like a broken radio picking up brief parts of a signal.

He couldn't be sure, but he felt he knew why the nightmare had begun. It had started after he had gone to bed with Elana. Was it guilt? Was a twinge of shame manifesting in these nightmares? He had not been in touch with the Satos since that night, except a few times he'd talked with Elana on the phone, their conversations abnormally formal. Yui had nodded her approval that night, as she watched her son and daughter fucking. Elana had been the one to tease and initiate their sexual chemistry. Even before that, his mother had pleased him orally in her bedroom. He disappeared into his thoughts for a while.

The path forward was obvious to him. He needed to speak with Yui. Lay it all out in the open. He texted her, asking if they could meet. She replied instantly, asking him to visit her at her home.

It was a testament to her staggering beauty that Isaac's troubled mind was swept away instantly as soon as he saw Yui. Sunbathing by the pool, she wore a simple white bikini. The size was too small for her, not that he was complaining. The material strained to keep her ample curves in check. Isaac drank her in. Yui raised her sunglasses, finally noticing him.

'You like the bikini, Isaac?' she teased.

'Uhh, yeah it looks great on you. Although maybe its not the right size?'

'They're not mine. Rose asked me to pose for some sample shots for work. I've got a pile to get through', she gestured to her side.

Isaac finally noticed the tripod camera and a bunch of swimsuits on the recliner.

'Rose is here too?'

'Yes. Elana's gone shopping. How are you, Isaac? You haven't been here for weeks.'

'Just a little busy with work. That's all'

'You said you wanted to talk about something?'

He hesitated. He had hoped to find Yui alone in the house but Rose complicated things. Yui caught on to his hesitation.

'Why don't you just stay and watch the shoot? After we're done, we can speak privately. And- Ah! here's Rose'

Rose was all Hollywood again. In her sleek black bikini, she looked like a movie star. She held a camera lens on her hands as she walked up to them.

'Hi Isaac. Nice timing. I need some help with my shoot', she said cheerily.

'Sure. What do you need me to do?'

'Oh. You don't have to do anything; I doubt you're used to professional shoots. I just need you to rate the swimsuit mom wears. I'm working with a company to market swimsuits and they need some shots for a calendar.'

'Sounds easy enough.'

'Great! Just sit down and relax. Mom why don't you get changed into the blue one?'

Yui walked up beside him to pick the swimsuits, laid out on the recliner next to him. She bent forward, thrusting her ass in his direction as she gathered the swimsuits in her arms and headed for the changing room. Just before she went inside, she gave him a wink.

Unsurprisingly, watching a beautiful woman in tiny bikinis pose seductively for a camera was fun. Isaac relaxed, occasionally commenting on the various swimsuits. Rose was a natural. She guided and advised Yui on how to pose. She had a good eye for composition and Isaac marveled as he watched her pictures. They seemed to bring out a certain sensuality.

'You're amazing at this Rose', he complimented her.

She smiled brightly.

'Don't forget to praise the model', Yui joked from across the pool.

She's right to brag. She was on her knees, her back facing them and her head turned backwards to smile at the camera. The one-piece swimsuit was backless, flaunting the ridges of her butt. He gave her a thumbs up in mock admiration and she laughed.

There were sleek two pieces, full body, thongs and skimpy bikinis. Isaac had a tough time keeping his boner in check, which constantly threatened to make itself known infront of Rose and Yui. Finally, the shoot was done. When asked which one was his favorite, he had a tough choice to make. The easy choice would have been one of the skimpier ones, but he took his job seriously.

'The lacy black one piece'

Both women arched their eyebrows in unison. It was an unexpected answer. Perhaps they too had expected him to go with one of the skimpier ones. The bikini in question was an elegant, relatively conservative design. It covered the breasts and abdomen fully, with intricate designs woven in between. It also covered Yui's incredible ass almost completely. But it was the best one, he thought.

'Oh?', asked Rose

'I don't know how to explain... it's classy, stylish. It fits perfectly, highlights the body without exposing too much skin, and contrasted nicely with Yui's skin tone'

His mother and sister looked surprised, then nodded.

'Thankyou Isaac. That was quite thoughtful and observant of you', Yui nodded in acknowledgement.

'All right. I'm going to get to work on these. Thanks mom, Isaac'

With Rose gone, Yui turned to him with a look of admiration in her eyes.

'Your taste is... refined'

'You looked amazing, although you could wear scraps of cardboard tied with string and make it look hot'

'Flattery... that gets you places Isaac. Maybe I have one last bikini to show you, as a thank you'

'Gladly'

'Not now. Later tonight'

He nodded. The mention of the night to come brought back the anxiety he had been feeling all day. Perhaps noticing this, Yui put her hand on his shoulder in a gesture of reassurance.

'Let me change. I'm going to take you out for some lunch, and we can talk.'

XXX

Her dark, lovely eyes were intense. She was anticipating what he had to say. Isaac kept the conservation light at first. She did not try to cajole it out of him, and he was grateful. When they had run out of small talk, Yui took charge of the conversation.

'I'm a little surprised... maybe a little upset with you'

'Why?'

'It's been three weeks since you last visited. You haven't responded to my calls. Your texts are brief. I thought we were getting along a lot better Isaac'

He began to speak but she shook her head.

'Now I would not imagine telling you how to live your life, how to cultivate relationships you want to maintain. I'm the last person on earth who gets to lecture you on that. But. I'd still like to know what you are upto. How things are going on in your life. If you do not want that kind of back-and-forth relationship, you need to tell me and I will respect your decision. My impression so far has been that you enjoyed spending time with us, if I misunderstood this, let me know'

Isaac admired her tact. She was giving him an opening to talk about his conflicted feelings so naturally.

'I'm sorry. Really. The reason I haven't been in touch is, well, that night'

'I see. You think it was a mistake?'

'It's wrong. All of this is wrong. Even before... that night in your bedroom. It should never have happened. Yui, this is so fucked up. I can't get my head straight. I know it's wrong, but I can't help myself. It's like a spell over me.'

Something changed in Yui's eyes at the end. For a moment, he thought he saw something conflicted in her eyes. But it passed. Yui took a bite of her lunch and he waited for her to respond.

'A spell? Well, I must admit I tried to -uh- cast a spell on you. The night we first met; I came downstairs to seduce you. I was... intrigued. I already told you this before but let me tell you why. I wanted to know what kind of man you were. I wanted to know how you would react. Of course, I can't deny how attracted I was, and am to you. I thought you would give in, just like I wanted to. I wanted you to follow me into my room. It was the first time someone resisted my advances. I was both dismayed and happy that you didn't'

'It's all wrong', was all he could say.

'Why?'

'It just is'

'Are you sure? You don't sound convinced'

'Too many boundaries are being crossed. I would have thought after seeing me with Elana you would put a stop to this, instead you nodded, as if approving'

'It's not upto me to approve or disapprove. I encourage Elana and Rose to be independent and decisive. What they choose to do with their life, the relationships they build and foster is their decision. It is not my place to chastise them. I will always be available for you, for the girls when you need someone to talk to, for advice and guidance.'

'So, what did you think when you saw me with her?', he pressed her for a clear answer.

'I only saw two consenting adults. Their pre-existing relationship is irrelevant to me. I don't conform to how humans see these things.'

'You really are okay with all this? How could you be okay?'

Yui fixed him with an intense stare, and her voice took a lusty tone.

'You came into my room Isaac. I undressed for you, then I gave you a blowjob. I drank your cum with relish. I'm more than okay.... I'm happy that you came into my life again'

He shivered involuntarily. She's wild.

'Wow. I don't know what to say', he finally replied.

'We are an unusual family. If you want to, we want you to be a part of it more intimately'

'I haven't told Elana you saw us'

'She already told me, Isaac. We share these things openly', she winked cheekily.

He had his answer. Though it didn't really solve his conflict. Isaac knew that it was wrong, yet her words made sense. When she explained her rationale, he wanted to believe. Yet something deep inside of him refused to accept. It didn't trust her words, her intentions. She's hiding something.

'What are you thinking baby?'

'You're.... uh... well...'

'Perverted? Immoral? Depraved? I've heard it all before. Tell me'

He blushed. Those words had crossed his mind briefly though he would not say them out loud.

'No! That's not what I was thinking at all, I just....'

'I don't take offense with those words. In fact, I delight in them. I would rather be true to myself and my nature, than pretend otherwise.'

'Your nature? Tell me more about you then', he pressed her frankness further.

Yui took a sip of her drink.

'I will. If you do something in return for me'

'What is it?'

'Tell me why all of this is wrong. You keep insisting it is but there must be a reason why'

'I need to explain why sleeping with my half-sister and getting a blowjob from my mother is wrong?', he countered.

'Then why did you do it if it's so wrong? I admit I tried to seduce and influence you, and you resisted. Yet you returned of your own volition. If it was so wrong, doesn't that make you a hypocrite?'

He was taken aback. For the first time since he had known her, Yui had called him out like this. He couldn't find the words to explain himself. Perhaps it was the harshness of her calling him out, Yui's expression softened.

'Yui, I'm confused. You say these things so casually, like it doesn't matter. Like you don't even care about the consequences. I can't help but feel like you're hiding something from me'

Yui's heart hammered. A lesser mind would have crumbled under the scrutiny, but she was a force to be reckoned with. This is for the good of us all, she reassured herself. He had matched her blow by blow so far. Strong, confident, unafraid of acknowledging his own flaws. His thoughts were jumbled, so very human. He just needed a push.

'There are things I haven't revealed to you. It's true. But I promise you I will, after you answer my question. Tell me why our relationship is wrong, and I will reveal all', she meant what she said.

'I can't think straight. I haven't been able to for a while', he conceded.

'I know just what you need to clear your head. Tonight, we're going out dancing'

XXX

He had expected a ballroom, soft jazz, bright lights and a stage. The dark strobing lights of the swanky club caught him off guard. He had been out clubbing before with friends, decided this was not his thing. With his stunning mother in tow, he found out he couldn't care less. People stole glances, some stared openly at her. Of course they did. She wore a short one-piece dress. The tight blue fabric hugged her frame. The end of the dress hiked up her thighs, just barely covering her ass. Short, practical heels on her feet. He led her to the bar and ordered shots. They downed three shots of tequila each. Her hair was down, parted on both sides but kept loose.

'Aren't we going to dance Isaac?', she yelled over the din of dance music.

'Too crowded here. Let's find a more private corner', he yelled back.

'It's a club. There are no private corners here'

'I really wish there was, this isn't really my scene'

Yui nodded, gestured him to wait and walked off. He followed her with his eyes, she climbed up the stairs and spoke to security as she pointed to a more sectioned off area. The security guard nodded and let her through. Yui walked up to a group of people occupying the private stand and spoke with them briefly. Like magic, the people got up and left. She found him through the crowd and gestured him to follow.

'How did you do that?', he asked as he met her in the stand.

'I have my charms', she giggled.

'This is far better. The music was boring into my skull'

'You talk like a much older man, Isaac. It's a club! Come on, let's dance. No one here to bother us'

'I'm not much of a dancer', he protested.

'That's what the alcohol's for! Don't worry about dancing. Just move your body to the rhythm. Here, I'll lead, you follow'

Their spot wasn't super spacious, but it was enough for a few people to dance freely. Isaac watched as Yui began to move. Subtly at first, then more expressively. Her hypnotizing movements drove back his awkwardness. He downed a fresh drink brought up by staff and walked up to her. She pressed her body to his and began to move rhythmically. He copied her, twisting his body to follow her movements. It was an easy, natural thing. The flashing lights occasionally illuminated her gorgeous face, her expression happy and carefree.

Buzzing with the alcohol, his inhibitions driven away, Isaac danced with Yui. It was a suggestive dance, like they were courting each other. Their bodies pressed together, feeding off of the closeness and chemistry, the dim surroundings giving them privacy to get wilder.

He grabbed her by the waist, pulling her body even closer. She gently bounced her ass, driving into his hips. The speed and force increased gradually, until they were dry humping aggressively. His hands reached upward, and he began to fondle her breasts through the dress. She moaned, pressing her head into his shoulders. Isaac reached down his mother's neck and laid soft, gentle kisses. Her perfume was subtle, richly aromatic. He took in her scent, the feel of her creamy skin, the sensation of her ass pressing down on his boner, her large breasts in his palms. The walls were collapsing, his worries disappearing. He let go her breast and reached behind her head to grab her hair. Twisting her face towards him, they kissed passionately.

The next hour was spent much the same way. His mother responded to his desire without hesitation. They kissed, grinded, groped and moaned in unison. He was sat on a couch, Yui straddling him. The straps of her dress were to the sides. Her breasts were almost spilling out. His hands were behind her, fondling her ass greedily. Their mouths unglued finally, a glazed expression in her eyes. She sighed deeply as he gave her ass cheeks a gentle tug.

'You like my ass, baby?', she said in a teasing voice.

'I like all of you, but your ass is something else'

'You can play with it anytime you want', she cooed.

Their moment was interrupted. A girl walked up beside them and spoke in a bossy voice.

'Please, this maybe a club but there are rules here. You're getting a little explicit there with the lady'

Yui's eyes snapped on the girl and her voice came out like an acid whip.

'Don't talk to my son that way. He's just having a nice time with his mommy'

The girl looked dumbstruck for a moment. Then she laughed, likely taking it as a joke.

'Alright, alright. I don't mean to interrupt your little roleplay. We have some strict rules about nudity and explicit behavior. Just keep them in mind, that's all'

'I'm afraid we're bonding here, and I just can't help myself', she turned back to face him and plunged her mouth into his.

The woman spoke again, testily.

'Maam, I'm going to have to ask you to stop and leave'

Yui broke their kiss and was beginning to speak but Isaac interrupted her.

'Sorry, I think we got off to a bad start. Why don't we come to a compromise. We'll dial it down a bit, and in turn you can stay here to watch, supervising us, of course'

Yui looked at him in surprise then back to the woman. Her face flushed and she struggled to speak, before finally nodding and sitting down quietly opposite to them.

'How did you know?', Yui gasped.

'She could have sent a security staff, someone more intimidating'

'Still, asking her to watch. That was bold'

'Well, she came here for a show. Let's give her one'

Yui arched her brow.

'And how far will this show go?'

He paused.

'I can't cross that line. Not with you. Please'

She merely nodded.

'I understand'

'Are you okay with this, her watching you?'

'Isaac please. Haven't you guessed what a naughty mother I am? Now, show me what you want to do with your mommy-slut'

XXX

A cab took them back to the Sato house. Isaac was lying on the bed wearing nothing but his boxers, pillow propped against the headboard. He watched his mother with the girl from the club. The girl's clothes were heaped on the floor. Yui was still dressed. They kissed softly, tongues pushing back and forth. Yui paused after a bit.

'I'm sorry beautiful, but my manners left me. What's your name?'

'Aiko', she whispered softly.

'What a beautiful name for a beautiful thing like you'

'Thank you, what's yours?'

'I'm Yui. And that's Isaac'

'Can I ask you something Yui? What you said back there.... are you really his mother?'

She looked at him in answer.

'Yes, we are. My mom is beautiful, isn't she?', Isaac said.

'Mmhmm. That's no naughty, so fucked up.... I love it!', she said breathlessly.

'Before we invited you to join us, were you watching us Aiko? Were you watching our erotic play?' Yui's voice was teasing, leading.

'I just saw two hot people having a great time, I didn't expect to be invited... but I'm glad you did'

'So am I. My son was having a conflict, Aiko. I wanted to take his mind off of things, I thought some dancing and fun would do him good'

Aiko looked towards Isaac with lust gleaming in her eyes.

'What kind of conflict?'

Yui gently pushed Aiko to the bed. The girl slid up to him, taking her bra off. Her body was slender, petite. He slid her panties off, noting a heart shaped tattoo on her inner thigh. She reached for his crotch and tugged off his boxers. Her hand instantly gripped his erection, and she began pumping.

'My son is conflicted about our relationship; he thinks it's wrong. He's... lost. I can see the desire in his eyes, his want. I asked him why, and he hasn't answered me yet'

Aiko took his cock in her mouth and began to lick the tip. He moaned in pleasure. Yui watched. Aiko did not talk further; she was too busy. His placed his hand on her head and pushed gently. Aiko began to suck harder. Yui chuckled softly.

'Kids.... So eager to feel pleasure, but unwilling to do the work for it'

Yui stood up and sauntered onto the bed. She caught Isaac's palm and placed it over the nape of her neck.

'Massage her softly', she commanded. He did as she asked.

'Pleasure is not a one-way street. The act is carnal, but the fullest joy comes in comfort and understanding. Your partner will appreciate gestures. Comfort her, let her know that you care about her experience too'

Aiko moaned in response as he gently massaged her neck. Yui kneeled down beside Aiko and watched. The girl was giving him an eager blowjob but lacked proper technique. Then again, he doubted anyone could take him to heights of oral pleasure like his mother beside him.

'Slow down, Aiko. I like your zeal. Every man loves a warm mouth wrapped around his cock. But let's make this fun for you too'

Aiko let go his cock and looked at Yui expectantly.

'Look him in the eye. Tell him you want his cock in your mouth. Let him know you want him to enjoy this. Make him understand that you do this for his pleasure'

The girl grinned naughtily and made eye contact with him.

'I want my mouth to make you feel good, Isaac. I want your hard cock to fill my throat'

She began blowing him again. It was slower, more intentional this time. She moaned now. He looked at Yui for instruction. She nodded towards her. Isaac gently cupped her face and began to stroke her cheeks. Aiko looked up and held her gaze as she swallowed his entire length.

'She's pleasuring you because she wants you to feel good. Thank her baby, tell her how well she's doing. Let her know how grateful you are', Yui's eyes twinkled.

'Your mouth feels amazing... thankyou Aiko.... I'll try my best to make sure I can make you feel just as good'

Aiko, her throat filled with cock smiled through the corners of her mouth. He felt a strange sense of gratitude and a desire to give her his best effort. Yui rolled off the bed and walked inside the closet. Isaac was too lost in pleasure to notice she had left. She cleared her throat upon returning. Isaac looked and.....

'I did promise to show you one last bikini, if you can even call this one', she said cheerily.

It was less a bikini and more flimsy strings tied together. Bright pink in color, the sling bikini was literally two threads. The threads descended to the breasts. The cloth was slightly thicker around the nipples, trying and failing to cover them completely. The threads led down to the crotch, once again struggling to cover her pussy. She turned around slowly. The twin threads continued behind her back, not even bothering to cover her ass.

She turned around again to face him with a wicked smile on her face.

'What do you think baby? Does mommy look good?'

Of course she did. Anything would look good on her. The unimaginative 'bikini' did nothing to dampen her beauty. Instead, it highlighted her large breasts, her toned physique and her tight ass. She climbed on the bed again, her tits jiggling. It was a marvel they stayed in place. Isaac was sure a breeze in her direction would cause her tits to spill out.

She lied on the bed, stretching her magnificent body fully for him to see. Aiko was still busy worshipping his cock.

'It's trashy, isn't it? Elana's idea of a joke. You should have seen her parading around the house, hers is black in color'

'I wouldn't mind seeing her in these... or you', he said absently.

Aiko resurfaced, a line of spit clinging from her chin to his cock. She looked at Yui in wonder.

'It's.... your body is out of this world Yui. And it sounds like I'd love to meet this Elana. Who is she?'

Again, Yui looked at him for confirmation. He nodded.

'Elana is my daughter. And the source of Isaac's conflict', she winked at Aiko.

Aiko's eyes went wide again in wonder. She laughed out loud.

'This is just.... amazing. You've been banging your sister? Man, this is the hottest thing ever. I'm so glad I met you guys today' Aiko was delighted, the perverted details of their relationship were turning her on even more.

'Aiko, sweetie, I didn't recognize you for such a dirty freak!', Yui cheered.

'Look, I'm dripping already', she gestured in between her legs.

'Mmm, let me warm you up', Yui said as she pulled Aiko towards her.

Yui shifted infront of Isaac, pointing her ass towards him as she began to lick Aiko's pussy. The girl moaned and fell back on the bed. Yui gestured at Isaac with her hand, and he joined her. The mother and son took turns eating out Aiko. Yui continued to instruct him.

'Slower, steadier. Focus only on her. On the sensations and taste and the promise of what's to come'

He obliged, feeling a sense of power as the girl's moans were renewed under heightened pleasure. Several minutes into it, Aiko's legs began to shake. Her body convulsed as she orgasmed powerfully. Yui chuckled behind him.

'How does it feel to give a girl an orgasm?'

'Powerful', he replied.

'And now it's time for the main act'

Recovering from her orgasm, Aiko simply smiled and spread her legs wide. Isaac stood in front of her, his cock ready to penetrate her. Yui opened a drawer beside her bed and pulled out a condom. She tore the packet and came up behind him, pressing her breasts against his back. Her hands reached around him, and she put the condom on deftly. Her hands left tingly sensations on him, and he nearly came.

'Gently now, give her time to adjust to your size', she whispered in his ear.

He slid inside Aiko, eliciting moans from the girl. For a few minutes he fucked her with the tip of his penis. The girl relaxed into the easy rhythm. Each time he backed out, Yui's tits pressed into him. When Aiko began to thrust her hips, he knew she could take more. He pushed more of his length into her and slid in easily.

'Place your hand here and rub her clit. There's no perfect technique, just feel her reactions till you find what works for her', Yui directed his hands above her mound.

He found the pace she liked and was shocked to see how the simple gesture increased her moans. Yui had moved to the side and began sucking Aiko's tits. Her suckling noises drove him crazy, and he reached out for the other breast, fondling and twisting the nipples. The fucking continued to increase in intensity as Aiko's moans turned into shrieks. She was babbling incoherently. She came again. He slid inside of her fully now. Yui teased Aiko's nipples for one last time, grazing it with her teeth before letting go.

'Aiko, sweetie. Tell him what you want'

'De- Deeper. Harder *gasp* harder pleaseeee'

'Turn your partner around Isaac. She wants it deeper; you need a better angle without hurting her'

Isaac caught Aiko around the abdomen, and she laid down on her face. He was ready to go in again, but Yui stopped him.

'Comfort first. Place this pillow on her stomach. It'll cushion your thrusts'

He did as told and began to fuck her again. This time he didn't need to ease himself in. He slammed into her in deep strokes, each one extracting a deep moan from Aiko. Yui watched with pride as Isaac fucked his partner with confidence. After a few minutes, Isaac looked at Yui.

'What is it baby?', Yui asked.

'She's ready to take it even deeper, aren't you Aiko?', he asked.

Aiko's only response was to whimper and nod her head. Yui shifted and once again pressed herself into his back.

'Then give it to her baby. Show her everything I taught you'

Isaac stretched and laid on top of Aiko. He supported himself with his arms on either side and rammed into her mercilessly. Aiko and Isaac moaned and grunted in unison as he plunged into her fully, the angle providing even more pleasure than before. The steamy sex drove Yui wild too. Unable to stop herself she laid herself into Isaac's back fully.

'So strong..... like a stallion. Can you fuck her with mommy on your back?', she breathed in his ear and nibbled it softly.

Isaac was beginning to tire, but Yui's words inflamed him. With a newfound strength he pushed himself back and forth. Yui's added weight caused his thrusts to go even harder than before. Aiko was screaming wildly, begging for more. She orgasmed yet again. The thought of fucking a woman to climax, with his mother lying and pushing on his back was too much. Isaac's own orgasm began to form. Ejaculating into the condom would not be enough.

He slid out of Aiko, her pussy convulsing and clenching his cock one last time. Yui climbed off him, instinctually understanding what he planned to do. She peeled the condom off in a single, smooth motion. As Isaac fell on his back, Yui swallowed his cock to the base of his shaft. Her tongue flicked out, licking his shaft and aching balls.

Isaac grunted deeply as a powerful orgasm tore through him. His mom's cocksucking was heavenly. Every inch of his cock was being massaged at once. He came inside Yui's throat. She looked at him, so full of confidence and drank every drop. The wave of the orgasm lasted far longer than it usually did. He was utterly drained. Finally, Yui relented. She pulled off of him slowly, never breaking eye contact. She licked her lips and sighed in satisfaction. He stroked her cheek lovingly as he caught his breath.

'In my bathroom, clean yourself then fetch a wet towel. Your partner needs aftercare too', she said bossily.

He cleaned himself up then came back. Aiko was just coming to from the aftermath of her orgasm. He cleaned her softly, mumbling praise and compliments and she smiled lazily. Yui went inside the bathroom and came back shortly. She peeled off the bikini and climbed into bed. Isaac shifted Aiko and tucked her in. The girl was asleep in seconds.

'Sleep in my bed tonight', she said.

'Of course', he replied.

'I'm proud of you Isaac. You treated your partner with care and respect. You even tucked her in'

'Thank you for teaching me. The way you guided me.... I've never felt such power and responsibility towards a partner before', he conceded.

'Not even with Elana?', she asked coyly.

'That was different. I was basically following her commands'

'Well, I'm glad you understand. Sex is as much pleasure as it is power. Letting one rule over you means you're not experiencing all the joy in offering'

'You're quite experienced, huh?', he joked.

'I already admitted what a slut I am, baby. Does that bother you?', she asked concerned.

He paused for a while. No, he wasn't bothered exactly. He knew instinctively that Yui's appetite was voracious.

'Not bothered... no. I think you're a different beast altogether. I don't think - I know couldn't handle you', he finished lamely.

She laughed softly.

'If. IF we ever get together, I wouldn't want to be with anyone else'

Isaac looked at her. Half smiling, half frowning.

'I think I have an answer for my worries'

'Oh?', her wide eyes were expectant.

'I worry that this will lead to complications in our relationship. People get along for a while, but fighting, jealousy, anger takes over. What if that resentment builds over time and it fractures us?'

'People do fight. And they do get jealous. They are very human traits. But me and daughters aren't like that. We are open with each other. We share intimate details of our lives. And... well. We also share each other', she said the last sentence with an added emphasis.

He looked at her with surprise and she looked scared.

'Really?'

'Really'

She waited for him to reply, and the room was filled with silence for a few moments.

'That's..... new', he said.

'You think it's wrong, don't you?', she asked with a tightness in her voice.

'I don't know. I thought what I was doing was wrong, but I can't deny how good it felt. How great it felt tonight. Still, people always find ways to get hurt, and things go bad'

Yui sighed. Was the answer so obvious all along?

'You've been alone all this time baby. I don't think you had anyone in your life to guide you, to take care of you. You see people as intruders, strangers. You've been hurt before, abandoned.... even I am guilty of that. But this is a time for reparations. People are different, but families.... families fight and argue. But we are always there for each other. I promise I will always be there for you', she trembled slightly.

'I- I guess so. All I know is spending time with you guys, in this house makes me happy. I don't want to lose that.'

'Then it's time for you take the next step', Yui said as she got up on her knees.

'What's that?'

'It's time you became a part of this family, officially. I want you to leave that apartment and move in here. Will you do that?'

'Okay. I will'

She smiled happily and kissed him on the forehead.

'Good. Tomorrow we can get movers to bring your stuff here'

She got up and walked to the closet. She fished around the drawer before returning with a ring.

'This ring was a gift from my mother. I want you to have it as a token of memory, the day you found your family', her hands still trembled as she slid it around his finger.

He inspected the ring. It was one of a kind. The band was made of a dark black material shaped like horns. The horns were uneven in proportion. Instead of a gemstone, the horns protruded outwards

'These horns, what do they mean?', he asked.

'It's just ornamental... old family legends and the like', she replied.

'Thank you, Yui', he said gratefully.

'You're welcome. And.... If you'd like, you can call me mom. Or mother. Or mommy', she winked.

He smiled and reached out with his ringed hand. Grabbing her nipples, he tugged her towards him. His mother moaned and sat on his lap. His other hand grabbed her ass and they kissed passionately again. There was an eagerness in the both of them that hadn't existed before.

'My slutty mom', he teased her when they broke apart.

'Oh... Isaac. You haven't truly seen the depraved depths of this slut yet', her voice was lewd.

'And are you going to show me?', he teased her more.

She gave him a meaningful look and he felt his cock stir. Their teasing was interrupted by Aiko, who mumbled in her sleep.

'That was bold of you, asking her to watch us at the club', she complimented him.

'I didn't even know if it would work. I just had a feeling like she wanted to watch'

'Still, telling her we were related was a bold move'

'That was... well. Instinct. I get this intuitive feeling sometimes. I just knew she'd be into that', he replied.

'This intuition, tell me more about it', Yui's voice was suddenly serious.

He looked at her with confusion. She was staring intently at him, as if he'd just said something horrible. Her expression softened instantly, like she had just given something away. She shook her head and laughed. He couldn't help but notice how forced it was.

'Did I say something wrong?', he asked her.

'No. No. I get these hunches too. Sometimes, I can just tell things about people. I thought maybe you felt the same things I do', she answered him.

'You do? Maybe it's a little family quirk. When we were off duty, we used to go out drinking. I can't say I was successful with women... but I could usually just pick out someone I knew would be into me. They said I had a horny magnet', he smiled and flashed her the horned ring he was wearing.

Yui didn't reply immediately. Then, she broke into another forced smile.

'Maybe it does run in the family', she said simply.

They were both quiet for a while, lost in their respective thoughts. Isaac wasn't sure what had transpired just now. The night had gone from pleasure to understanding to confusion. Yui definitely was hiding something, and he debated whether telling her about his intuition was a mistake. A much more intense train of thought was running through Yui's mind.

This can't be possible.... but what if it's just a coincidence? Some people are just adept at reading social clues.... then again, he is one of a kind.

She glanced at him and realized his mind was somewhere else too.

'Isaac'

'Hmm?'

'I promised you I'd reveal some... secrets if you told me about your feelings earlier on'

'Okay. I'm listening'

She took a deep breath first.

'There is a way to change how you feel about all this. A way for you to enjoy our dynamic without guilt or shame. I can reveal things to you about us, things that would surely change your mind. This revelation would drive all hesitation out of you. I guarantee it'

'Tell me then, trust me I want to sort this out too'

'I'm sorry. Not tonight. I'm tired now and am sure you are too. So much has happened.... we need clear minds for this. Tomorrow we can sit down and talk. Just trust me on this?'

He nodded. Tomorrow then. Isaac fell asleep in a few minutes.

XXX

Yui could not sleep. She waited for half an hour to make sure Isaac was truly asleep then got up and left the room. She searched a drawer beside her bed quietly before finding her ring. It was almost identical to the one she had given Isaac. Forged in her home world, the ring had one special property. When used with focus, it could break down illusions.

Yui debated waking up Rose or Elana then decided against it. She climbed up the stairs to the second floor. From the landing she made her way to the door in the middle of the corridor. The door was open, inside was a simple home gym. She closed the door shut, then she placed her ringed finger on it. The air shimmered around it and the door disappeared. Thick vines replaced the surface. Yui pushed herself through, into the dark forest.

The fracture had moved again. She would have to go deeper into the woods now. After another hour of walking, she arrived at the fracture. Last time, it had been a cave, now it was a hut. Yui opened the door of the hut and stepped inside. She made sure not to touch anything she didn't recognize.

Reality fractures were tricky things. Doorways into other worlds had unexpected properties. She looked around carefully and spotted what she had come looking for. The full-length mirror was idle now. It reflected her naked form. She stood perfectly still and called out her name.

'Rhea, answer my call', her voice echoed as if she were in a tunnel.

She waited for a few minutes anxiously. It hadn't worked in two decades now..... but then she came. The mirror glowed brightly and out of it walked the succubus, Rhea.

In the dim light they could not see each other well.

'Outside, darling. I don't trust these fractures much', she grabbed Yui by the hand and they exited the hut.

It had been decades since they last saw each other. Rhea was still her regal self. She wore no clothes. Her black wings were folded. Her enormous, curved horns were wrapped in decorative jewels. Yui still remembered the softness of her platinum white hair. Rhea's skin was a light purple, elaborate tattoos covered her arms, legs, abdomen and the womb tattoo, resembling the curved horns of her own ring.

But most striking was the monstrous futacock between her legs. Even in her troubled state, Yui's eyes drank in that delightful appendage. Rhea chuckled.

'This particular gift often skips generations. Is your own daughter not blessed with one?'

Yui grabbed the cock and stroked it a few times. Rhea moaned in delight.

'She does. Though hers is not as big as yours, mother', Yui said.

'You were always in pursuit of extremes, my daughter. I remember when you begged Syl to chain you up in her room. How many nights did you spend, dominated by your sister?', Rhea asked fondly.

'Weeks... and do you remember those first days after my awakening? I must have memorized every inch of your cock then....', Yui said dreamily.

'You were a delightful little harlot, I could never satisfy you for long.....'

'It's good to see you mother, it's been a while', Yui sighed.

'Truly'

The mother and daughter succubi kissed in greeting.

'This power I sense in you... what is it? I have never encountered anything like it... is it the reason why I heard your call?', Rhea asked in surprise.

'I think so. I've been traveling into this rupture for two decades. Not once did my summoning work. I called for you, for Syl, for so many others of our kind. I just.... I felt it would work this time. This power is something else is it not? It's the seed of my son, Isaac. He is more potent than you can imagine, it's even stronger now than when I first tasted him. Potent enough that even my weakened powers were amplified for you to sense'

'There is potency, and then there is this. It shouldn't even be possible', Rhea wondered aloud then continued.

'But then again, he also should not be possible. A succubus birthing another kind.... what kind of mess have you found yourself in, my darling?'

'The kind with no straight answers', Yui replied dejectedly.

'No curse is unbreakable. Last I heard you were still looking for a way. Have you found it?'

'I found it, only there are complications. It's why I sought you again today, I'm dealing with something beyond my expertise', Yui said.

'What is it?'

'Isaac's father, his entire bloodline is descended from a hell-demon'

Rhea's eyes did not betray the shock she felt.

'Tell me more, spare no details'

Yui launched into the story. What she knew, she told Rhea. About the hell-demon, about its battle with the succubus Zarya, about the demon's human offspring and its eventual slaying by a hunter. Rhea did not say much but occasionally asked her to repeat certain things.

Rhea was quiet for a long time before she spoke.

'So the boy's father had an inert demon soul. His is too. What is this ritual?', Rhea asked.

'Soul Shatter', Yui replied quietly.

'Hmm. To shatter a soul into pieces... I take it you aim to swallow the demon half?'

'Yes. The demon half sprang the curse and weakened me. I will ingest it and regain my powers again'

'You will need a tremendous amount of strength for this. More power than even his seed holds', Rhea's voice was uncertain.

'My daughters will help. Between the two of them and Isaac's potency, there will be enoughr'

'Very well. This will work, daughter. Yet you speak of complications'

Yui hesitated, unsure of what Rhea would make of this. But she had little choice.

'I took Isaac dancing with me earlier. We were getting intimate when a girl came up to us. She... wanted to watch us, even knowing we were mother and son. I didn't think of it much at first. We ended up in bed a few hours ago...... Rhea..... it wasn't me. Isaac used a lure charm. He sensed the girl's desire, sensed she would like to join a mother and son. He - he can use the powers of a succubus without even realizing it'

Another long pause. When Rhea didn't speak Yui continued.

'He was born from a succubus. Is it possible for a human to learn our powers?'

Rhea finally spoke.

'The only way to know is to complete the ritual. But his potency may be a clue. I cannot make guesswork here, forgive me daughter'

Yui sighed, then smiled.

'It's fine mother. I wasn't sure there would be a way to know. But just seeing you, talking to you has eased my anxiety....'

'The path is clear. If his potency can grow stronger then you must continue to nurture him. Every trick you know, every technique... use it on him. Give him pleasures that only a succubus can. Do not dally, go now and join him in bed. The stronger he gets the faster the ritual can begin. I will wait for you at a threshold.... when the ritual is done, summon me again', Rhea said.

'Not so fast. I have yet to convince him. He is a little lost, and hesitant. I'm waiting for him to accept his lust for me. But yes, when that is done, I will tell him about the ritual'

Rhea's eyes narrowed a little.

'Is that hesitation I sense in you? If he desires for you then what is the point of waiting? Use your pleasures and break him'

'No. He must agree and understand before this can happen', Yui said firmly.

'Your curse has changed you. Remember! You are a succubus. This human sentimentality is not for our kind. Do not make the mistake of caring so much for that which will end so quickly', Rhea countered.

'I'm not sentimental, I just want to respect his wishes. I've already tricked and manipulated him so much; I can't do it anymore'

Rhea started as if to speak but changed her mind.

'Very well. I know you will get it done. Now come, we have not seen each other for so long, let us enjoy ourselves', Rhea smiled wickedly.

The tension eased instantly as the two demonesses reached the natural conclusion of their meeting.

XXX

Yui moaned and screamed in delight as Rhea slammed into her. Her pussy quivered as her mother expertly wrecked her into a dripping mess. Words were not necessary for the two. In their long lifespans, the two had frequently spent weeks and months together. Rhea bunched up Yui's hair in one hand and jerked her head upwards, knowing intimately what Yui enjoyed the most. Yui's head arched and so did her hips. Rhea brought up her tail, deftly guiding it into Yui's asshole. Having filled two of her holes, Rhea's tongue snaked forwards and wrapped around her daughter's mouth. Being pleasured everywhere was too much for Yui to bear.

She came again, and again, and again.

'There she is', Rhea laughed. 'The succubus. There's that insatiable whore I remember'

Yui laughed and moaned at the same time. She was in paradise now. She hadn't been fucked like this in literal decades.

'HARDER', she screamed into the night and Rhea obliged.

XXX

They lay on the grass as Yui caught her breath. Finally, Rhea stood up. Yui followed suit. The succubi embraced and kissed in parting.

'Oh, before I go, I have one last advice for you', Rhea said.

'What is it?', Yui asked as she got up and dusted off the grass from her body.

'When the ritual is complete and you ingest the demon soul, your powers will awaken instantly. You will be strong, and he will be weak. Do not hesitate, you must dispatch him swiftly'

An icy pit materialized in Yui's stomach, and she struggled for words. Rhea watched her reaction with a dark expression on her face.

'WHAT! I WILL NOT KILL HIM- HOW COULD YOU SAY THAT', Yui yelled.

'YUVANA!', Rhea roared.

Yui was taken aback, and she flinched. She had never known Rhea to raise her voice.

'You are a succubus. Please do not tell me you are this stupid and sentimental. What do you think will happen when you swallow the demon half? The boy will wither and die', Rhea said in a calmer voice.

'Why would he die? I can heal him again, after my powers are returned, I can fix his soul. You know how powerful I am with soul magic', Yui protested firmly, but her voice was panicked.

'A human soul can be repaired, his is not human, not fully. He was born with two fragments. Without one, the other dies. But that is not a risk you can take. We do not know what will happen with the human half. Likely it is corrupted already. Maybe it will seek to protect itself. DO NOT take that chance',

'RHEA! HE IS MY SON. I WON'T HURT HIM!', Yui's voice was cracking now.

'A succubus cannot give birth to a son! He is an abomination. You said it yourself... half human, half demon, and yet he can mimic the powers of a succubus... something like that is too dangerous and unpredictable'

'We do not hurt or kill living things! Not unless it is done out of self-defense. How can you suggest I do something so dreadful?', Yui pleaded.

'He is not a living thing; he's barely a thing. Even his soul is tainted and incomplete. A living thing can survive with its own life force, he cannot, not when the demon half is shattered and consumed'

Yui was stunned to silence now. How did I not see this coming? Was I so eager to regain my powers that I did not see the death that awaited him?

'You don't know him', Yui said at last.

'Neither do you, not really. I can tell even now that you understand this deep down. Why wouldn't you reveal our true nature to him otherwise? What man, what human would not want to bed a family of lusty succubi? One that is willingly, eagerly in his path. No. You hide because you know the same fear, that he will reject you, betray you. Trust your instincts on this, I beg you', Rhea finished with a hint of emotion at the end.

They were silent for a long time. Yui addressed Rhea.

'It was good to see you. I will be going now'

'The ritual ends in only one way. He will die no matter what. I'm sorry, I understand that you care for him. But it's going to happen', Rhea said softly.

'Then I won't do the ritual', Yui announced finally and turned around.

'Then what will you do? Yuvana, please. There is no way this ends well'

'I'll do what I should have done a long time ago. I'm going to tell him the truth. All of it.'

Rhea did not reply as Yui left. Lost in her thoughts, Yui reached the exit to the fracture faster than she realized. She stepped through the vines, emerging once again into her home. She pressed the horned ring into the vines, which shimmered and became a door again.

She slumped to her knees. Thick, hot tears spilled across her thighs as she cried bitterly. She had not felt pain like this for twenty years. But it wasn't just pain. It was disappointment. It was guilt and shame. It was remorse. And just as importantly, it was a sign.

Rhea had been right; she was becoming more human every day. The succubus Yuvana was fading into the dark. Isaac's presence in her life had just accelerated that process. She was no longer pretending to be the human, Yui Sato. Yuvana was desperate because she was dying. Yui Sato was not desperate. In fact, Yui Sato had a very clear idea of what would happen next.

She wiped away her tears and stood up. She went to the bathroom door beside her and turned on the faucet to wash her face. Outside the door, emerging from the dark cover of the night, Isaac made his way downstairs, his mind troubled. He had woken up to the same recurring nightmare only to find Yui was not in bed. Following a gut feeling, he had gone upstairs. He had arrived just as Yui sank into the floor and started to weep. Shocked and unsure what to do he had waited.

Hastily entering the bed, Isaac's mind raced through the events of the night. Something deeply painful was affecting his mother. Maybe it's the secret she wants to tell tomorrow. Maybe, maybe she's ill or dying.

He shuddered at the thought. Yui entered the room after a few minutes. He didn't let her know he was awake. She climbed into the blanket but did not go to sleep. Her hands stroked the back of his head softly and Isaac assumed she was lost in her thoughts.

'I'll never hurt you', she whispered to him before falling asleep.

I know you won't. Isaac thought, as he too drifted to sleep.

XXX

In the morning, they gathered for breakfast. Aiko was gone by now. He joined the Satos on the dining table, an unnatural silence echoed, as if everyone could sense something was coming. Isaac peeked glances around the table. Yui's face was masked in stone. Elana met his eyes and shrugged. Rose did the same. With their plates cleared and the kitchen cleaned, they retreated to the living room. Isaac sat down beside Elana; Rose a few seats away. Yui stood standing, shuffling awkwardly. They all waited, knowing now the moment had arrived.

'Isaac. I promised you that I would reveal my secrets. I'm sure by now you have sensed that I am hiding quite a few. First and foremost. I'm sorry. I have betrayed you, your trust. I lied and schemed and manipulated you since the day we met. I wanted to bring you into this home, I contacted you for that very reason. It wasn't just to make amends... I - I needed something from you', Yui's voice was uneven.

Isaac didn't say anything. He wasn't exactly angry yet, but he sensed the truth would be rough. Yui continued.

'My daughters and I are completely open with each other.... Elana seduced you under my supervision. I saw that you liked her too and let it happen. For what its worth she is quite fond of you, and even without my guidance I believe you two would have ended up in bed anyway'

He felt Elana tense beside him. He wasn't sure what to say. Sneaking suspicions were being fulfilled now. He nodded.

'The reason is... well. It's hard to explain without providing the right context', Yui looked at him expectantly.

'What is the context?', he asked.

'Do you believe in magic?', Yui said simply.

Isaac was taken aback. Is this a prank? Is she fucking with me? Rose and Elana were looking at him too now. He was almost convinced it was a prank. But their serious expressions could not be an act.

'Magic? Like tricks? Or like Harry Potter?', he asked unsure of how to react.

'More like the latter, only its not that simple', Yui replied.

He looked at her face, still anxious. He looked to his sisters, flabbergasted. They too wore serious expressions.

'This is a fucking joke, right? You're fucking with me?'

'No. I am not. What do you think?', asked Yui.

'I think, I'm tired of these euphemisms. If you don't want to talk that's okay, but you need to stop. You guys are scaring me now', Isaac got up to leave, angry.

A bottle of water on the coffee table shot upwards. He yelped and fell back on the couch. It continued to stay in the air. Swirling and drifting as if held by an invisible force. Isaac's mind was a total blank. He was still convinced this was a prank. He looked carefully at the bottle, hoping to see a wire or string somewhere. But there were none. Rose raised her hand, a pink glow covered her fingertips. She nudged her hand towards him, the bottle shot at him and stopped an inch away from his face. Rose jerked her hand again and the bottle flew back, landing on the table.

Elana shifted beside him. She leant towards a potted plant. The same pink glow as Rose's covered the palm of her hand. She placed her hand on top of the plant and raised her palm slowly. Isaac watched bewildered as the plant began to grow... really grow under her palm. She continued to raise her hand upward, until the plant was now a metre taller than before. Elana faced him, a reassuring smile on her face. Isaac did not feel reassured.

Elana flicked her wrist forward. Isaac gasped when he saw Yui's clothes begin to disappear. In seconds, his mother was naked in the living room. Elana stood up too. With another casual flick she was naked as well. Rose reached her hands down to her ankles. As her palm traveled upwards, her clothes began to shimmer. Tiny flames danced across the cloth as they too disappeared into nothingness.

Unsure of what to say, Isaac looked to Yui.

'O-Okay. Magic is..... real', was all he managed to say.

The Sato women remained silent as he processed the thought for a minute. Even their naked forms were not enough to distract him as he digested this wild revelation. He felt queasy, but also excited for some unknown reason. Magic is real!

'So. You are witches?', he asked even though he felt very stupid saying it out aloud.

'No, magic is not reserved for just witches and warlocks', Yui said.

'Okay', was all he could stammer out.

'Isaac. You told me last night that you wished to live without consequences of our relationships.... you said you wanted to be a part of this family. I'm telling you that you can. That you don't have to worry about jealousy or resentment that humans have. It's possible. Here. With us. There is no need to hide, no need to resent. We are not beholden to the sentimentality or morality of human beings, do you understand?', Yui's voice was tinged with a note of worry.

'Because you're not human?', he asked.

Yui nodded. She gestured Rose and Elana towards her. The girls walked up to their mother and stood beside her.

'Then... what are you?', Isaac wasn't entirely sure he wanted to know.

'We-.... we are not humans. Please, Isaac. I am afraid to say the word out loud. Can you guess? Go back to our first meeting. That night. You said it was like I was trying to put a spell on you.... Elana's instant attraction towards you.... what did you experience with us? When sleeping with Elana... when you were with me. The pleasure, its different, isn't it? The kind humans cannot experience by themselves', Yui finished.

He thought back now. His instincts, his confusion, his hesitation. It all pointed towards something... something he couldn't quite place. The answer was stuck somewhere in the back of his head, overwhelmed by the flood of revelations....

Think! Three women of inhuman beauty, their sexual prowess is otherworldly. They do not feel shame or guilt, they sleep with each other, they talk about existing beyond human morality.... There allure is like a dark spell of desire, they inflame passions... like luring a fly into a trap....

And then the answer came to him. Demons! Succubus! He looked at them with bewildered eyes, his mind a torrent of emotions. Shock, fear, rage, temptation, betrayal, lust, confusion......

'Show me', he said finally. His voice mirrored the bewilderment he felt.

A hint of nervousness passed through the three women. Yui bowed her head.

'Suddenly, I'm afraid', she whispered.

'Show me', he repeated himself with a hint of anger in his voice.

Rose stepped forward. Her head held high and proud.

'Isaac. Once the unknown becomes known, everything changes. Are you sure you are ready for that?'

He was slightly taken aback by the warmth and concern in her voice. Tricks! He nodded again.

'How much do you want to see? My true form is a little... unconventional. Perhaps, Elana should do it.'

Isaac turned to Elana. Her face was a little scared, but she smiled. Elana walked up to him. With a casual flick of her hands, she pushed the heavy coffee table to the side. Kneeling in front of him, she tucked her hair behind her ears.

'I'm so excited. I know things are serious right now, but I've been desperate to show you my real form'

She really did sound excited. Elana thrust her chin forwards to him. He took it as a sign and held it, steadily as she looked at him intensely. Her eyes glowed pink for a moment, then the iris changed color into a dark red. Isaac almost let go out of shock. Her red hair became glossy, and he actually gasped as the horns came out. They shot out of the base of her skull. The black horns protruded forwards slightly before curving backwards.

'More?', she asked.

'More', he replied.

The color and pallor of her skin began to change. It was the same color as her tan. Pale olive brown skin. He observed as the arch of her nose, the lines of her cherry pink lips became even more striking. If his little sister wasn't growing demonic horns, he could have marveled at how inhumanly beautiful she was. She looked at him with her red eyes.

'All of it'

She stood up now. Her tits, already big for her size began to swell even more. They were tight and perky despite being larger than her head. The light brown nipples began to harden. Her proportions should have been impossible. But the changes were still happening. A dark pink tattoo appeared above her pubic mound. It was shaped like antlers circling themselves. Her thighs became slightly thicker, and he realized she was growing taller. She grew almost six inches, the horns adding another few to her height. Behind her, Yui was growing breathless.

Then, finally, Elana revealed herself fully. Her beautiful brown wings, shaped almost like leaves unfurled and stretched to their fullest. And then her tail, shaped like a spade announced itself. It crackled with energy, swishing from side to side. Isaac's eyes could not leave her. He gaped at the wings in wonder, before the tail caught his attention. To aid his curiosity, Elana turned around, presenting her backside. The tail emerged a few inches above her ass crack. It was deep black in color. Her ass had grown too, although slightly. On her right ass cheek was a heart shaped tattoo.

Elana waited with bated breath. She beat her wings once and Isaac was struck with her alluring scent. She smelled like a fragrant garden. Perhaps it alluded to her leaf like wings and earthy complexion.

Finally, she turned around again. Isaac looked at his little sister with fire in his eyes. There was no denying he was aroused. She smiled, revealing pearly white teeth, her canines slightly sharper. And as a final touch, she stuck out her tongue. It was normal at first before the tip shifted. It elongated, long and snake like before retracting again. Elana raised her arms above her head, pressing her enlarged tits together and stretched her body with a soft, mewling noise.

Yui sat down on the couch beside Isaac. Her face was lined with worry. When Isaac did not speak, she reached her hand forward and grabbed his. Gently, she guided his hand, placing them on Elana's hip.

'Feel her', she said softly.

Isaac had half a mind to pull his hand back, but her skin was not like human skin. It felt like tiny, pleasant charges of electricity shooting up his hand.

'How does it feel?', Elana asked him.

How could I even describe it? His mouth was watering. Elana's skin was soft, and velvety and all he wanted to, all his mind and body screamed at him was to get close to it. He wanted to lick the skin, every inch and crevice. He wanted to graze his teeth and leave trails on it. He wanted to bite her, mark her with his mouth. He wanted to feel her horns, he wanted to grab his little sister, this inhuman temptress and take her - No. This is what they want. I have to resist.

He snatched his hand away from her waist. He looked to Yui and then to Elana.

'Elana....', he said.

'Elana is my human name, a derivation from my real name. I'm Eleanora. But you can call me whichever's comfortable for you', she gave him a reassuring smile.

He shook his head violently.

Seeing horns and wings had not shocked him as much as this admission. Perhaps it was that illusion, that idea he had of his little sister that was falling apart. Her face, enhanced in her true form was still her own. But Elana? Elana did not exist. Elana Sato was a deception. Just like Yui Sato and Rose Sato. The house of cards that Yui had built was crumbling down. Desire shrank in an instant as a deep sense of betrayal flooded Isaac.

He stood up abruptly and made towards the door. No one stopped him.

'Isaac', Yui's trembling voice called after him.

He paused and turned around.

'Please. I promised you the truth, there's more', she pleaded.

'I know what you want from me, demon', he said coldly.

A savage thrill crept through him as he saw the look of pain that struck their faces.

'No- not anymore... before, maybe. Yes... No! I had a.... this plan was in place... but no. There is no plan. Isaac, only truth. As promised... please. It doesn't even matter anymore. My mistake.....', Yui broke off her insane babbling.

'I want nothing more to do with you...... any of you. I know how this ends, succubus. Don't try to contact me again'

Isaac left through the front gate, convinced he would never step foot inside this house again. He looked back at the gates one more time, relieved that he had emerged from the lion's den unharmed.

In another world, a conspiracy was being hatched.

The priestess drained the rest of her wine and looked to Rhea.

'A soul that is both human and demon, yet capable of using the power of our kind. You were right to bring this to me Rhea, it is most troubling'

'So, we are in agreement? The abomination must be killed. I understand our aversion to violence... yet this must happen'

'We are not taking a life. His life is already forfeit. Do you know what kind of power it takes for an inert demon soul to survive for generations?', the priestess asked.

'You don't mean to tell me...', Rhea paused.

'When a demon dies, its soul dies. This is not an ordinary demon; its power must have been extraordinary. I do not believe this hell-dweller was killed'

'So, the demon lives? The boy's demon half is not inert, he is a host to the demon itself'

'Correct. Rhea. I ask a great deal of you, will you do it?'

'The boy is a threat to my own offsprings, of course I will do it', Rhea replied simply.

The priestess left the room, returning with a wicked knife in hand. She handed it to Rhea.

'A blade blessed by our goddess. It will drive out the hell-spawn out of the boy. Do not hesitate. Death is a kindness compared to the fate that awaits him should the demon awaken again'

Rhea nodded, slipping the black knife back into its sheath.
