Polyamory.
It was a concept and philosophy where at least multiple people, not limited to just two, love each other openly and honestly. It emphasizes choice regarding the number of partners one can choose instead of adhering to social norms such as monogamy.
That was something that a man in his late thirties, Shidou Takamiya, had chosen for himself. He has a wife. And he has a mistress. All agree with the conditions involved, and in light of their situation, their relationship is a well-guarded family secret.
The man was handsome and had a light stubble on his chin, along with a muscular build. He had dark blue hair and amber-brown eyes, which now glowed with pale yellowish gold. He sits on the bed alongside two women. All of them didn't have their clothes. That was because they fully intended to consummate their relationship. Two women loved the same man, and both agreed, after hashing out the details, to share him, and also agreed that no one else would be let in on this relationship.
The one on his left was Rinne Takamiya, a woman in her late thirties. Shidou's beloved wife. The very epitome of a perfect housewife. She had a beautiful face, with brown eyes that had now turned into a glaring red, feeling a little anxious. Her body was voluptuous and developed, with her D-Cup size breasts, and an alabaster complexion skin. Her long hair flowed down to her back. His wife was just godly and a heaven-sent, in terms of her body. She was the woman Shidou had promised to truthfully love with all of his heart, and have a happy life with.
The one on his right was Sona Sitri, a woman in her late thirties. Shidou's chosen mistress. The very ideal of a seductive professional co-worker. She had a beautiful face, long black hair that had a white maid hat on the center, with violet eyes that glowed ominously and with anticipation and anxiety for what was to come, covered with her dark violet spectacles. She too had a voluptuous and sexy figure, with well-enshrined C-Cup breasts, which wasn't something she had back when she was younger, which was when she was in high school, and her breasts developed over time, maturing along with her body, which seduces Shidou to the bone. She was the woman that Shidou had grown attracted to. He felt a burning sensation of love and lust intermixing with this woman.
How did this all start?
Shidou couldn't tell exactly. He and his wife had already met Sona long before this, during what was known as the Convergence. It was a time of chaos, when various worlds merged, and its inhabitants would meet. Shidou can still remember the hell that occurred during that time. Natural disasters. Zombies coming out of the woodwork. And other major nuisances.
It was around that time when he met Sona. But he never really actually had feelings for the woman immediately, and the same could be said of her. They, and practically everyone else, had far more important things to worry about.
It was probably around the time when Shidou and Rinne had Rio again that he began to slowly gravitate towards Sona. Naturally, they didn't think much of it, and tried to change the subject whenever the subject get's brought up. But... at some point... Shidou couldn't deny his unnatural attraction to Sona any longer.
However, before all of that, he would honestly inform his wife of his budding feelings on the matter. His wife, kind and understanding to a fault, only gave him a sad yet understandable smile.
"...Thank you for being completely honest with me, papa," Rinne would say with a sweet smile. "That being said, I can't deny that I'm a little hurt that you do have feelings growing for another woman."
"If... If you don't want too, Rinne, I can stop and pay no heed to it," Shidou spoke with a depressed tone.
"No," Rinne shook her head. "No, that would not be very fair to you. You have sacrificed more than enough, for the world, for the rest of the Spirits, for our family... let me offer something back. I will give my approval of your relationship with Sona-chan. And, actually, in some way, I'm glad that it's Sona-chan that you chose."
"Why?" Shidou looked at her incredulously.
"Because I feel that, among the women we both know, Sona-chan happens to be the most level-headed and reasonable person to get along with in a relationship. Our daughter looks up to her too, ever since she had dedicated herself to tutoring her about various subjects, including harnessing her Spirit Energy. Sona-chan is also my best friend. I would be more than happy to welcome her into our family, especially," Rinne paused a bit, smiling sadly. "Especially when she really does need someone to be a part of her life."
What his wife referred to was the current status of one of the current rulers of the Underworld. Sona Sitri was practically the only one among the Maous who did not entertain the idea of having a relationship or marriage compared to her fellow Maous. Ergo, that resulted in numerous vyings for her hand in marriage, which she all rejected, earning her the nickname of the "Raven-Haired Cold Beauty". It's a little on the nose, considering her manner of handling things professionally, and had the bloodline of the Sitri that had an affinity for ice magic.
Another thing was the fact that Sona has a certain dilemma. She shared it with both Rinne and Shidou long before it got to the whole polyamory situation. She secretly desired and wanted a family. When everyone in her life, her peerage, her fellow Maous, everyone she knew had already gotten married and had children, she was practically the only one left. And there's also the fact that Sona happens to be the last Sitri left. Serafall Leviathan and the other former old leaders were dead. The entire Sitri line was dead.
Sona was the only one left. And she was, for all intents and purposes, alone.
"...Shidou," Sona would say to him one time. "...I love you."
"...!" Shidou looked at her with a subtle, yet surprised and anxious face.
"...That is the truth," She said, looking at him in the eye. "I truthfully, deeply have fallen in love with you. But," Sona would make her position known. "I will not betray my best friend, your wife, just to satisfy my feelings on the matter."
"...But why are you telling me this now?" Shidou asked.
"Because I wanted to find some closure to this," Sona muttered softly. "I want to have you, in fact, I envy Rinne truthfully. I've seen how happy you, Rinne, and Rio are together. I felt like an outsider, an intruder, someone who shouldn't even belong in your home. I'm only here simply to be a friend in need for Rinne and Rio's tutor. Those are the facts. Nothing more, nothing less."
That's what Sona said. But then, Rinne would convince her otherwise, as she informed Sona about her husband's genuine confession and resolution to take Sona, and only Sona, as his other woman, his mistress, his lover, his sexual partner.
And thus comes full circle to now.
"Hhmmm... it's a little embarrassing like this," Rinne softly laughed a little, in light of the slight tension between the three. "I've never actually done this kind of thing before."
They were all naked. Sona couldn't help but feel like drooling and ogling at the muscular torso of the man she was going to have sex with. The man who was married. Sona had become his mistress, with his wife's approval. This felt like an unnatural dream come true. Her heart was beating fast, as her left hand placed itself on her breasts, seeing the man look at her a lot.
Sona wasn't blind. Shidou wanted to fuck her. Right now. The feeling was very, very mutual.
"That... makes two of us... And I've..." Sona muttered, with an embarrassed expression. "I've never had actual experience in sexual intimacy. I've... I've read about it, but... actually doing it feels... a little scary."
Shidou's eyes sported understanding. He would look at Rinne. "Ne, Rinne... do you think I can have sex with Sona first?"
Sona looked at him with widened, questioning eyes.
"...Hmm, actually, that would be fair," Rinne nodded, before looking at Sona. "Of course, that's if Sona-chan is okay with it."
"I...I'm okay with it," Sona muttered, putting her hands to the bridges of her spectacles.
"Then...I'm going..."Shidou would slowly draw forward and gently caress the devil woman's right cheek. He felt the woman's trembling hands slowly placing themselves on the muscular chest. They would slowly draw their mouths towards each other, and place their lips softly, kissing one another. They would slowly move their faces to and fro, as Sona savored every single kiss. Her left hand raised itself to caress the man's cheek as she kissed him, in-between her gasps and need for air. Then a final kiss as they looked at each other.
"Turn around, Sona," Shidou spoke, with pale golden eyes glowing.
"Hmm," Sona nodded slowly as she hesitantly moved herself back, now crawling on all fours as her vulva was on full display for the man to look. The man would stand a bit, bending his knees to the proper position. He would gently place his strong hand on the woman's ass, making the latter shiver a little in anticipation as she glances at him with blushes and embarrassment.
Shidou would turn left to see Rinne drawing near to him. She would raise her lips towards the man and kiss him, with their faces moving to and fro, savoring their respective locks, and the caressing touches of the man's face on Rinne's part. And they finished with a final kiss, as Rinne caress him on the chest, with a trusting look as she kissed him on the cheek, before opting to embrace him from behind, making Shidou feel the woman's heavenly breasts.
Rinne was the angel. Sona was the devil. A perfect fit.
Shidou would place a hand towards Sona's soft rear as he would draw his manhood closer. But...
"Ahhm~!" Sona, much to her surprise, was feeling something going deeper inside her anus. In a word, she was literally having a stick on her ass. "Ahh~! Uhhm~! Ahhm~!" Sona's rear naturally shook from the pressure as it embedded itself deep inside the rectum. The process was complete, as Sona felt like an explosive euphoria was taking over her completely.
She glanced at the man who was dominating her. She could see the man looked at her with gritted teeth and an interested look.
"...Ne, Sona," Shidou muttered softly. "I've always wanted to do this, to fuck you on your ass... iit's just sexy to look at..." Shidou shot an apologetic look towards Rinne, who understood as she kissed him on the lips.
"...Papa, don't worry, I don't mind. Just do what you need to do," Rinne muttered seductively towards him.
Shidou nodded. Then he turns his gaze back at Sona. He would gently lift the devil up as he placed his hand towards the latter's breast, making her yelp a bit as she felt like rising, as her front was exposed.
"And I always wanted to play with your breasts," SHidou muttered softly, whispering to the woman's ear. He would begin to tug the woman's back hair, making her yelp and grit even more. "And I've wanted to play with your hair. And you should know, you're... actually the first woman I've ever had this kind of position with."
Sona looked at him incredulously, before Rinne confirmed. "Hmm... Admittedly, I was surprised a bit that he seem to want to experience something like that. It just had to be you," She answered with a soft smile. "Don't worry, Sona-chan, Shidou and I have been talking thoroughly about this issue. This...This may be a bit selfish of me, but let him do with you what he likes."
"Hahmm... Hhhmm," Sona nodded, as her sultry look was mow forming at Shidou. "I didn't think you'd be this perverted, Shidou, and I thought Hyoudou-san was perverted."
"Does that bother you?" Shidou asked her.
"No..." Sona shook her head a bit. "No, actually, it's... it's wonderful, for you to actually think of me as a desirable woman."
"Well... then I'm going to start right now," Shidou said as he lifted Sona's chin to his face and performed an amorous kiss, passionate and firm, and at the same time, shook the woman's rear with a thrust. Then follows another, and another, and another. Shidou would try to take it slow, not only to savor the moment, but also to make sure that Sona doesn't get hurt too much from the taboo fucking.
Rinne would offer Shidou more kisses as she rubbed her breasts to the man's back and torso.. On the man's shoulders, back, and sides of his face, Rinne offers kisses of sweet reassurance. It's okay, is what she would say. You can have sex with Sona, release everything you want on her if that's what you want, I'll support your decision, she thought.
Shidou felt so fortunate to have a wife like this. It made him feel relieved and alive as he was pumping his dick back and forth through the ass of this sexy devil.
"Ohhm~! Ohhh... Fuck... Fuck me... Oh, yes... Shidou, fuck me good~!" Sona muttered, as she provides her own contributions by moving her ass naturally. She just loves the fact that the man is treating her so roughly right now. Sona wasn't a masochist by any means, but she just couldn't help but indulge in the roughness Shidou is displaying with her.
"Errhmm... Your ass is so sexy, Sona," Shidou said, thrusting her back and forth, making her yelp and moan. "I've always wanted to do this with you."
"Then keep doing it, Shidou~! Keep doing it~! Ahhhm~! Keep fucking me however you want~!" Sona said as her eyes raised upwards.
Shidou's thrusts were going faster and faster. Rinne continued to offer her kisses to all of the man's sweaty parts and offered kisses to his lips, and a warm embrace. Shidou at the same time would doggy-style Sona, still grabbing hold of her hair as her face was now looking upwards in pure ecstasy. Oh yes, Sona thought, she felt so good. Her knees lift herself up just in the same position as her man, as her ass shakes for the married man who was bedding her.
"Keep it coming~! Oh yes~! Do me in, papa~! Oh yeah~!" Sona spoke in delirium and smiles.
"Hmm..." Shidou groans as he felt an explosive stress reliever with the woman's ass and his wife's kisses. "Shake that ass of yours, my sexy devil. Shake it."
"Ohhm~! Ri...Rinne...~! This...This isn't fair...Your husband's just... Oh...It's so godly," Sona spoke in delirium. Rinne understood that Sona meant no malice on it and it was just the sex talking.
"Hmm, but don't forget, Sona-chan," Rinne would counter with a tease as she kissed the man's lips softly before saying. "This man's my husband." Rinne said as she kisses the man again.
"Ahhm~! Ohh~! You...You did not just go there~! That's not fair~! Shidou, kiss me too~! Kiss me while you fuck me so hard~!" Sona begged as she felt the various thrusts imposed upon her.
Shidou accepted as he dragged Sona's face near his and kissed her passionately, with Sona letting her tongue do the talking for her, licking his mouth and teeth, and inserting deep into his mouth. Then the kiss ended, and Shidou kissed Rinne again, with the same amount of passion, which was only exasperated by the tremendous thrusts that he was giving to Sona. Then, after kissing Rinne, he would kiss Sona again. Then back and forth.
Their body auras were now covered in a mixture of pure white-bluish and violet crimson. They glowed as things started to heat up and continued. Shidou lost count of how much time he spent fucking the devil woman's ass. He was just enjoying it. He felt like he was slowly developing a fetish. He was experiencing what may be the closest thing to a threesome. Though... Shidou doubts that Rinne and Sona would go that far, as they both only find interest in Shidou. This entire idea of them doing this together was already pushing it a little.
Rinne's love and Sona's lust for him.
"Grrkk... I'm coming now..." Shidou muttered, tugging Sona's hair. "I'm coming now, Sona..."
"Urrhhmm~! Do it~! Come to me, Shidou~! Uhhm~! Ahhhmm~! AHHHHHHHAMMM~!" Sona could feel the explosive climax and the various amounts of semen that poured into the woman's anus, while the woman released her own juices underneath her vulva. Shidou gritted his teeth as he gasp for breath. He finally did it. The devil woman's rear was reverberating naturally from the thrusts and semen, and opted to create a farting-like effect, making Sona a little embarrassed.
Shidou would turn his face towards Sona and kiss her passionately, with slight movements from their crotches. He would slowly release himself from Sona's anus, as he was kissing Rinne, who was positioning herself properly towards him. Sona laid down a little from the bed as she glances at the man with a sultry look.
Rinne placed her finger delicately on his girth and carefully placed it inside. Then she puts her soft hand at her man's shoulder as she lowers herself down. As she did so, she would feel the tip touching the edges of her vulva, making her pen her mouth with an 'O', her cheeks feeling like it was burning red, as her eyes flashed with a glowing ominous scarlet, shining as bright as a diamond.
Shidou in turn felt a wave of comfort and pleasure, and he was not just talking about what lay underneath him, though that forms part of it. He found his breathing steady as his darker, depressive thoughts suddenly went away. Memories of happiness; of the times he spent with his wife and daughter were slowly seeping through his mind. Beautiful is the one word he could describe. Her maternal bosom and figure is greatly enhanced over his vision. She emanates an aura of bliss that makes him forget most of his worries. His beloved wife. His heart which always heals him with a caressing warmth and touch. His woman who always offers companionship. His crotch now lay deep inside his wife's maidenhood, one that he had entered so many times, both of their souls being connected.
"Sona-chan," Rinne muttered, looking at Sona, who rose himself up a little as she crawled. "Why don't you take the first kiss while I move?"
"...Hmm," Sona spoke as she drew her man's face to her point of view, allowing him to see the prize of his heart. Shidou saw an offer of pleasure worth. A body that respected and ravished with delight. The black-haired woman's violet-entrancing eyes would look at Shidou with a burning desire. Shidou could feel his wife moving her waist, back and forth as his manhood thrusts deeper into his wife's vulva, feeling subtle waves of spiritual comfort. Sona would caress the man's face and made a passionate, soft, touching kiss, one that made him kiss back as he slowly moves his hips, hearing a few muffles from Rinne's voice as she felt her hips shaking, softly grinding his crotch.
Shidou raised his left arm to bring Sona's sexy body over to him, as he passionately sucks the woman's breast, making Sona sported an 'O' look, gasping for breath. He sucks the devil woman's breasts as Rinne was grinding his dick. Sona would lift his face and kiss him passionately. As his hips were moving slowly for Rinne, he was kissing Sona with a soft gentleness and passion, as they felt their tongues tease and were coming inside of their mouths, exploring every nook and corner. Shidou's left hand traced the smooth arching back of his other woman while his left hand gently touched and caress the right rear cheek of his wife, massaging it a little.
Shidou draws Rinne's body close to him, letting go of his kiss with Sona as he raises his lips to Rinne and receives his kiss, with softness and pure warmth; passion now takes over as they both would accelerate their grind of their copulatory organs upon one another. Rinne's D-Cup breasts were now laying down upon Shidou's torso as the latter embraced her figure, with his thrusts growing more active, and Rinne followed in sync with her movements.
Shidou lets go of his kiss with Rinne to focus on Sona who draws her lips towards him to initiate another passionate kiss, feeling her hand to his face. His right hand would now trace itself towards her vulva where he would slowly place her finger to touch it. Sona let out a muffle as she felt something entering her, teasing and preparing her womb for her turn. Rinne in the meantime was content to embrace Shidou, laying her neck on his left shoulder, her red eyes glowing, asking for more thrusts upon her, which Shidou obliged willingly for his wife.
His left hand placed itself on his wife's back while his right hand continued to finger Sona's vulva, making the latter moan as she kissed him with passion, with tongue-tied twists. Sona glances as she sees Rinne drawing closer to their man. Sona lets her lips go, allowing Rinne to kiss him in her place. Sona felt the hands of her man fingering her lower chambers, making her bit her lips as a part of her wanted to be thrust by her man too, but she was practicing self-control at this very moment. This was all for her man's sake.
Sona had never felt so much happier to be able to do this. Finally, as if her wish was granted. Shidou Takamiya, whom she thought was realistically beyond her reach, was now having sex with her. And his wife approved of their relationship, something she never thought was possible, because Sona knew just how much Rinne loved and was possessive of Shidou. Sona was admittedly envious of Rinne's relationship with him. Shidou was just one of a kind, someone that Sona would never be able to look in another man, or devil.
Sona grew disatisfied at the number of suitors that were vying for her hand in marriage. She could clearly see their intentions just from their looks alone. Shidou was different. He had helped her in more than a few ways, especially the skill she sorely lacked which was cooking. A loving husband and father. It was something Sona had covetted and wanted for herself. Now... she was getting a taste of it...
"Ahm~! Ahm~! Pa..Papa~! Ahm~! Can you...go faster~!" Rinne sported a pleasurable and sultry face, her heart expressed through it which overlayed a newfound joy and happiness. Her red eyes glow with that happiness, looking upon her man's now pale golden eyes. He wanted his woman now. His focus was now on his wife, whom he powers forward with his striking rod of divine perfection.
Faster. Faster. Faster.
"Haaahhhhmm~!" A climatic release ensued with streams coming out from Shidou's manhood, shooting straight into his woman's womb. His fingering of Sona's vulva essentially caused the woman's juice to be brought out as well, with Sona moaning in pleasure.
Afterward, both Rinne and Sona would kiss the man's face as if a job well done.
"...Papa," Rinne muttered softly. "Now it's Sona's turn."
"...Are you sure?" Shidou asked, glancing at Sona who was looking at him hungrily. "We may take a little while before I get back to you, mama?"
"Hmm, I'm sure," Rinne spoke with a caring smile, caressing his cheek. "Let me have my rest for a little bit. You can go all out with Sona-chan as much as you want."
"...I see," Shidou muttered, before he kisses her. "Alright." He said as he gently let Rinne down on the mattress. Then he turns his attention towards Sona, whom he drags towards himself, as Sona attacks him with a ferocious, hungry kiss, with pleasurable moans, as they both can breathe their own free air. Sona's breasts were rubbing the man's chest while her arms were locked towards his neck. Her vulva was rubbing towards the man's pelvis that was standing erect.
After another passionate kiss, Shidou spoke with Sona. "Ne, Sona... let's fuck over there," He indicated towards one of the tall poles nearby. Sona, who look at him, nodded with a sultry smile as she understood what her man wanted. She kissed him, before she would crawl towards the side of the bed and stood up. She walks towards the pole, and holds it, leaning towards it with a seductive look, as she was showcasing stripper-like movements on the pole.
Shidou smirked as he crouched to the side of the bed and stand up. Then he would walk towards Sona, who was still moving and shaking her body and ass for his own personal benefit. He touches the woman's ass, making her sultry and desirable. He kisses her for a bit, before he eventually plunges his dick towards the woman's ass, making her moan.
