Author Notes: This story is not connected to any of my interconnected stories project and is its own story.

Years ago, there had been a mysterious cataclysmic event that resulted in two universes merging. The World of Spirits and the World of DxD. Since then, things have changed, for better or for worse. A new era had dawned. No longer was the supernatural hidden like a masquerade. No matter where you go, you will find humans and non-humans interacting with each other without so much as batting an eye. The power vacuum among the pantheons settled in, and thus new people needed to rule over the old positions in order to quell the potential chaos that may ensue.

Things have changed, and life more or less moved on. For Shidou Itsuka, that was so. In the beginning, he was once a Savior of Spirits, tasked with sealing their powers via a kiss, and giving them normal and happier lives in the process. The Spirits had all moved on with their lives, yet they still kept in contact with him.

Now, he was happily married to one of the Spirits, and had a lovely daughter with. His life never felt better. Everything was finally over. No Wescott. No DEM. No world-ending threat. Nothing. Everything was normal and peaceful for him.

...Then.

A certain spark happened for him.

"Hmm..."

A man and a woman, mesmerized and enchanted by the look in their eyes. Their faces were slowly drawn towards one another as their mouths opened to perform a soft kiss. Simple yet effective, which sparked a flame that was already there and would build up to engulf them.

The man who initiated the kiss was Shidou Itsuka. A man whose handsome face and body are indicated to be somewhere in his late twenties to early thirties, with dark blue hair and amber-brown hardworking eyes. He wore a dark blue shirt and grey pants.

The woman he was kissing... was not his wife. It was someone who had become a friend of the family over the months that passed by. She had long black hair that reached to the middle of her back, a youthful face that spoke of a cool and collected beauty, violet eyes that could allure even a steel-disciplined will which are reflected upon her red stain glasses, an amply developed bosom hidden beneath her clothing and shapely modest figure, and slender legs. She wore a black business suit normally suited for the office, with a white collar shirt, and a black skirt that covers up to her knees.

Her name was Sona Sitri. And she was a devil. Literally. Figuratively. She was someone who was the headmistress of his daughter's school, Auros Academy, which was a prestigious academy where both humans and non-humans go. It did not matter if you were a human, a devil, an angel, or anything else. Everyone was welcome to receive the finest education available.

Shidou first met her when he was about to pick her daughter, Rio Itsuka, up from her school. Then while he was there, he would bump into a woman holding a few papers.

"Ah! I'm sorry!"

"It's... It's fine."

Their eyes met at that moment. The moment they saw each other, they felt that their breath was taken away from them. For Shidou, his eyes felt drawn towards the woman's eyes. Entrancing, mysterious, alluring, and even a little seductive. Her face and skin were white as snow. Her beauty, reflected on the physical, as well as with the interesting eyes that bore into him. At that moment, he felt hypnotized by this woman. They stare at each other, even as Shidou helps Sona out with her paperwork.

"...I'm sorry for bumping into you just now," Shidou spoke with a contrite yet awkward smile.

"...N-N-No reason to be sorry. It was I who did not notice you, umm-" Sona spoke while putting one of her hands to the bridges of her glasses.

"Umm, my name is, uh, Itsuka Shidou. And umm, you are?" Shidou would ask with a stuttering tone.

But before Sona would answer...

"Sona-sensei!"

Sona got hugged from behind by none other than Shidou's daughter, Rio Itsuka, a young girl of seven years of age, with long plum hair that reached her legs, tied with one single braid, and had a blue bow on top of her head. Her uniform was of elementary size, a white long-sleeve shirt with red wrist collar lines with cross-like edges from the center, with a red bowtie found on the collar of her shirt, along with a light brown vest with two lower front pockets. She was also wearing a long black skirt that reached her knees, with white long socks and black shoes.

"Ah, papa!"

Rio smiled cheerfully and brightly. That was the first time Shidou and Sona met, and it was somehow through Shidou's daughter, Rio. The irony did not seem lost to Shidou. Afterwards, it led to a few conversations and an exchange of phone numbers.

As the night fell, Shidou was lying down in bed alongside his beautiful and beloved wife, Rinne Itsuka, who was fast asleep and embracing him. a beautiful woman somewhere in her late twenties to early thirties, with short light pink hair, with part of it tied up in a braid, a perfect face that resembles a purely reminiscent angel which touches and calms Shidou's heart, and light brown pure yet firm eyes. She was fast asleep right beside him, embracing him. While he feels the familiar comfort from which he finds value and strength to carry on, his mind is elsewhere. He could not forget about the woman's face. His heart became a little strange and mixed. His eyebrows were knitting. For the first time in his life, it seemed like he genuinely grew interested in a woman other than his wife.

Little did he know at the time that Sona was thinking about him in the same way.

Sometime after that, Shidou and Rinne, while they went out for grocery shopping, found themselves bumping into Sona who was shopping for groceries too. At that time, Sona and Rinne became fast friends and exchanged their own contact lists with one another. Rinne was in fact the one who would help Sona out in terms of the kitchen, which tends to end up more of a mess than not, because Sona as it turns out, despite her intelligence and etiquette as a noble devil princess, was actually rather bad in cooking, prompting Rinne and even Shidou to teach her the basics of cooking.

As stated, Sona was a devil, but not just a devil, but a pure-blooded devil who is currently the ruler of her own clan, the Sitri. Then there were the other responsibilities that she had such as heading an academy and of course, governing the territory of Tenguu City. Years before, Sona had been entrusted with taking care of the city after a few deals and negotiations, thereby making it her and the Sitri Clan's territory. Tenguu City was at the current moment a buzzling fine city with urban landscapes, technological marvels, and other futuristic aesthetics that made such a contrast to what it was years ago, back when Shidou had been dealing with sealing the Spirits at the time.

In all that time, in the months that followed, Sona would eventually become closer to the Itsuka Family. She would visit them whenever his schedule allows. In fact, she acted as a kind of private tutor for their daughter in terms of spellcasting and other forms of magic. As a natural-born Spirit reincarnating into a normal human who had undergone a natural birth, Rio had this gift and aptitude for magic, something that surprised her fellow classmates, and Sona, noticing the child's potential, took it upon herself to train the girl.

In those same months, Shidou felt... drawn to Sona. He experienced a tension that he never experienced before when he would always be around her. Sona felt the same tension, and in some cases, would sometimes try to avoid Shidou and try to calm herself down. Sometimes, Shidou would notice Sona glancing at his direction with a kind of subtle yet intense and sad look, before her attention was quickly brought elsewhere. Other times, it was when Shidou had been teaching Sona about how to use the kitchen and how to cook. As he was holding her hand, they stared into each other's eyes. The tense feeling then was strong and urging. Instincts were crawling deep into their being. Their hearts felt in sync. Shidou stared into Sona's face and noticed a little red blush on her cheeks. Her lips were tempting, almost like a forbidden fruit. It was very hypnotic to him.

It was more than fortunate that Shidou and Sona were interrupted by Rinne, otherwise, they may have gone into places that they would never return from.

...Until now that is.

"Ne, papa."

"Hmm? What is it, mama?"

There was Rinne Itsuka, a beautiful woman somewhere in her late twenties to early thirties, with short light pink hair, with part of it tied up in a braid, a perfect face that resembles a purely reminiscent angel which touches and calms Shidou's heart, and light brown pure yet firm eyes. She was wearing a simple white and red dress. On her arms, she was carrying their sleeping precious daughter, Rio Itsuka, who was wearing a simple white and blue dress.

"I'm going to be taking care of Rio for the time being, so I'll head upstairs," Rinne smiled a little before kissing Shidou on the lips. She would glance towards the sofa and see Sona, relaxing on the sofa and watching the news reports. "Sona-chan, if you need anything, my husband will be here to provide whatever you like." She said, winking one of her eyes a little.

"Eh-Uhumm, thank you, Rinne," Sona softly spoke, looking at the television while covering her tense and trepid expression.

Shidou felt a shiver down his spine. Alone with Sona? While Rinne and Rio were upstairs? Well, he thought, it's not like anything is going to happen. That was what he thought. As Rinne and Rio left for the bedroom upstairs, Shidou was left alone with Sona. With nothing else to do, Shidou would begin to sit on the sofa, though he would keep his distance a little from Sona.

"Umm, you can come closer you know," Sona proposed with an encouraging, kind smile. "It's... It's not like I'll bite or anything."

Shidou would reluctantly grow closer to Sona as they sat quietly together, watching the news.

They sat quietly as they watched the news. At some point, there was a certain dragon emperor that was seen on the screen, making a speech that... made both Shidou and Sona sweatdrop a little.

"And so, peace would thus be restored, so that all men of this nation would enjoy the natural glories of oppai! OPPAI! OPP-OW!"

Said dragon emperor got bonked in the head by his crimson-haired wife, Rias Gremory, who looked rather annoyed and embarrassed.

Sona sighed. "Sometimes I wonder how Rias manages to survive with him as a husband."

"W-W-Well, he isn't that bad, Hyoudou-san I mean," Shidou spoke with a wry smile, recalling how he once met the person a few months back. "He's just an honest person."

"Too honest," Sona shakes her head. "Sometimes I feel that it is better to keep such things to oneself."

Shidou twitched a little. Keeping things to oneself. "Right... honest."

"In any case, I..." Sona spoke before... she noticed that Shidou's tense yet conflicted and serious face was a little relatively near. Her heart was beating at the moment. She felt like her throat was drying with thirst. Her eyes were twitching a little. Their hearts clouded and beating. They felt dizzy.

"...I...what..." Shidou muttered softly, his expression glancing a few times at the television before turning back to Sona.

"...I...I thought that..." Sona spoke hesitantly, trying to distract herself with the sound of her voice and the noise on the television, but to no avail, as it felt like she was drawing in closer and closer. Her face was instinctively drawing near to Shidou's. Some part of her wanted to resist, stopping her face from reaching his face.

"Thought... what...?" Shidou asks again as his face draws near.

"I... I..." Sona couldn't help but draw her face again.

Then, the next thing they knew, there was a soft kiss. They tested their lips, brushing each other, inhaling each other's breath, and felt the warmth and the taste that made them feel like their worries seemingly vanished. They let their kiss go and stared into each other. Their expression turns to one of slight surprise, realizing what they had just done.

"...So-Sona," Shidou spoke as he tried to get away, trying to stand up from his seat. "I-" But Shidou was cut off by a delicate hand grabbed his arm and pushed him down to the sofa. Sona was now sitting right on top of him, determined to no longer let him go, putting both of her hands on his shoulders. Her glasses were lowering a little as her conflicted violet flashing eyes were boring down on Shdou's surprised brown eyes.

At that moment...

"Hmmph~!"

Sona would initiate a more passionate kiss, one that Shidou found himself drowned by as he instinctively touched the waist and the rear of this woman. They showed a desire that they had long tried to control. A hunger and thirst for the other as their lips and mouths ran wild, creating smooching and muffled sounds that were covered for the most part by the television that was still on. Their faces turned left and right, right and left as they kissed. Sona's glasses flowed to the rhythm. Their tongues twist and fight for the right to dominate the other. The urge to become one was strong for them both.

Months of trying to hold back were now becoming more apparent. Shidou's hands would lower themselves inside Sona's office skirt and would remove her black panties, with her legs allowing the removal quickly. He could feel Sona's hands massaging his hair and face as they lowered down to his shirt's buttons, removing them bit by bit until the only thing that remained was his black shirt. Shidou in turn would remove the shirt buttons from Sona's white collar shirt, and exposes her ample breasts covered by her black bra.

Then Sona would, along with Shidou's help, roughly try to remove a little of Shidou's grey pants, removing the zipper and button, then it would fall down on its own. The only thing that was seen was grey underwear. Sona would remove his underwear a little and his manhood would now be exposed in all its glory. Discarding foreplay altogether, Sona would go in for the kill and move a little upwards, lifting her skirt off as she jumps down and tackles Shidou's manhood, inserting itself deep inside her.

"Ugh!"

"Uah!"

Now, they were both one. Shidou groaned a little, gritting his teeth, as he felt hotter and pleasurable underneath, feeling like he was being squeezed from the inside out. He could hear Sona's moans, gasping for breath, widening her violet flashing eyes, as she felt something being pulled inside her. They looked upon each other's eyes and a mixture of feelings settled in.

There was guilt and yet there was passion. There was a desire for the other. A craving. A lust that could not be extinguished. A perfect fit, and yet something that should not be. Sona's hands were now placed on the man's shoulders as she made the first move.

"Ugh! Uhah! Umah!"

Sona instinctively rocks her body with senseless abandonment. The stimulation was consuming her. She romps and grinds underneath Shidou's crotch. Shidou instinctively moved his rear along with Sona's as they both were now in tandem. Their movements were becoming faster and more aggressive. Sona would move up and down, her breasts bouncing with every motion of her body. Her face was directed at Shidou who was gritting his teeth, feeling both pleasure and pain, on many different levels.

Shidou felt a new kind of experience as he continued to rock his crotch along with Sona. This was a bit different from how he did it with his wife. ...And he liked it. He liked the thrill. He liked the excitement. There was this element in him that awakened. Their pounds were becoming more consistent as they went faster. Shidou could hear Sona's moans coming out bit by bit. Her mouth was wide open as she tried to breathe the free air.

Shidou was mesmerized by Sona's figure and demeanor. Her sultry movements as her eyes looked at him. The calm and collected beauty, reduced to nothing but a lustful and desirable woman that was now romping up and down with him. At last, a twisted thought in Shidou's mind erupted, this woman was now his to do as he pleases. He felt selfish and guilty for doing this. A part of him would whisper. What about Rinne? What about Rio? His family was right above them. He loved them. Truly. But now, he desires this woman who was giving him an ecstatic new experience.

As Sona moved up and down, her thoughts were all directed at the man who was making her into this. How did this even happen? She was doing this with a man who was the husband of her best friend, Rinne, whose friendship she treasured genuinely. In fact, it even felt like Rinne was kind of a sister to her, something that Sona had lost when she lost her older sister, Serafall Leviathan, during the events of what is known as the Trihexa Crisis, which was more or less responsible for the power vacuum at the time.

So why...? Why was she doing this?

Several things led up to this moment. She thought of the times when she and Shidou would simply confide with one another about their lives. She remembered that one time when she was on the beach, wearing modest black swimwear at Rinne's suggestion, and both of them would show themselves to Shidou, who felt speechless at that very moment. She remembered the light touches from Shidou's hand. She remembered his kind affection for children, and was especially a good father to Rio and a good husband for Rinne. She acknowledged Shidou's hardworking nature, working for the organization Ratatoskr as an engineer so that he could provide support for his family. She saw Shidou's helpful attitude with other people, like the time when Shidou was helping a woman across the street, or was helping a friend out with something and had given one hundred percent to the task laid before him. She admired many of his positive qualities.

Then admiration turns to fondness. She never thought that any man could make her blush in a way compared to how she blushes with Shidou. But then, a shattering reality hits her badly. Do not try to pursue him. The logic and morality in her head dictated. The man had already been taken. He has a family to love and take care of. She isn't allowed to butt in.

But still... Sona could not help but love and desire him. She strikes with ferocious pounds, making Shidou grit his teeth as the sofa moves along with their bodies. Sweat was now slowly covering their skins, feeling the heat coming from their clothes. Her selflessness gradually took the form of selfishness. She was now coveting someone who was the husband of another. A devil, true and true. But at this moment, she didn't care. She wanted him and she wanted him inside her, now!

Pounds continued on for what seemed like hours. They lost track of time. The noise on the television felt so far from their hearing. They never stopped and continued full throttle. Both were deeply focused on the other, immersed in the pleasures of the flesh.

"Shidou! Uah~! Shidou!" Sona said.

"Sona! Ughh! Sona!" Shidou said.

They tried to speak a few words amidst their passionate endeavor. Their names were mentioned in their mouths. The pleasure felt so intoxicating that they wanted to be conjoined to one another forever.

"...So...So...na... I..." Shidou gritted his teeth as he tried to speak, feeling his mind drown in the fires of passion, his waist moving and pumping inside Sona. "...I."

"Hai... Hai..." Sona spoke, muttering as she spoke with a hypnotic tone that pleased Shidou's ears.

"...I... I love... Rinne..." Shidou finally uttered. He said it, and yet it seemed like a contradiction.

"...Auh! Amm~! Why! Why are... are you saying this... now..." Sona spoke as her jumps increased at the mention of Rinne.

Shidou continued as tears slowly poured out in his eyes. Regret and sadness. Guilt and remorse. But all of those transforms into a power that never quenched as his lust for this woman was now driving him on.

"I love... Rinne... I love my wife... I love my family... I... I don't... I don't want to lose them!" Shidou spoke as he aggressively throttled Sona. He placed both of his hands behind her back and pushed her towards him in an embrace.

"Auh!"

Sona exclaimed with moans as she felt her bosom lower down to her man's muscular chest which was covered with his shirt. She felt his warm hands and embrace her all the while continuing to pump her inside and out with a reckless abandonment. Shidou strikes back with a vengeance as he pumps through Sona like bread and butter, making her moan a little loudly, yet focusing on keeping her voice down a little.

"Is it alright?!" Shidou asks, conflicted, as he draws up and down Sona's vulva, increasing the waves of pleasure that cover Sona's mind. "Is this alright?! I... I want you! I want you, Sona!"

"Uah! Yggh!" Shi-Shidou! I... I want you too! I want you so much!" Sona exclaims a little, rocking her waist back and forth.

They increase momentum. Sona wanted to mate and be one with this man. Her worries about him being married seem to no longer matter. He was someone she could no longer live without. This may be selfish on her part, but Sona wants him. She wants Shidou Itsuka, the kindhearted family man who would help others even if it hurts himself. She wants him. She needs him. Her soul was drawing towards his soul, like a magnetic frequency that could not be stopped. With every strike from both herself and Shidou, penetrating deep into her womb, she wanted him.

"That's why..." Shidou embraces Sona as he aggressively strikes back with up-and-down movements from his crotch, making her moan. "I want you by my side... as much as I want Rinne. I want you here, Sona. I want you as much as I want my family..."

"Uaah! Hai! Uhh! Hai!" Sona exclaims a little.

Shidou was now being selfish for this very moment, compared to most of the times he became selfless. He still loves his wife and daughter, however, he also wants another woman to be by his side, to make love with him like this. He wants to do this with her forever. No, he doesn't want to be selfless, not with this specific case. He wants Sona Sitri. The beautiful and sexy devil that is driving her womb close to his heart.

"...I...I want you...as my woman! I want you to be mine, Sona!" Shidou exclaims.

"Uaah! Hai! Uah! Hai!" Sona exclaims as a lustful expression and wide smile enter her face. She felt a mixture of emotions ranging from lust, shame, possessiveness, regret, and other complicated traits.

They pounded each other hard and never stopped doing so. Sweat was now present on their skins. A climax was now approaching them. More. More. More.

"UAah! Take me! Uah! Take me, Shidou! Uaah! Take me, uaah!" Sona exclaims.

"Sona! Sona! Sona!" Shidou growls her name aggressively.

And then...

"UAaaaaaaaaaah!"

"Grrrrrkkkk!"

A climax happened. A release of liquids of lust and passion occurred underneath. A bright flash of violet was seen to occur from Sona. Her mouth was wide open. Shidou deepened his embrace, as he felt Sona's soft breasts and heartbeat from his torso. Their breaths were labored. As they returned to their senses a little, they noticed that the news was now over and a commercial was now in place.

They would lift their faces at each other, seeing each other's labored expressions. They would kiss once more. They were still hungry and they wanted more.

Shidou and Sona would move on to the house kitchen, a sacred place where Shidou and Rinne would cook for the family. It was also a place where Sona had learned how to cook. They place most of their clothes at the top of the base cabinets. Sona would suggestively place herself near the sink, putting her hands close to the sink for support.

Shidou removed his black shirt and placed it on top of the base cabinet. Next, he would remove the back portion of Sona's bra and place it in the same base cabinet. Sona in turn would put her remove panties and bring them to the same base cabinet.

"Ah!"

Sona could feel the touch of the man's hands on her breasts, once a source of shame, but now endowed with a modest yet perfect figure. The way Shidou held her breasts made her feel like a queen who was respected.

"Uaah!~"

"Grrrk!"

Shidou, drawing his face near to his woman's left facial cheek, shoulder, and ear, his breath making her feel aroused, would once again deliver his manhood inside of her. Shidou pushed deeper, eliciting moans from Sona, making her eyes glow brighter. Then she felt her face turn to the left, with her man's left hand redirecting her chin, and a passionate kiss ensued. Then at the same time, Shidou would pound hard and allow him to feel the soft rear cheeks of his woman, savoring each impact of his crotch. It was now time for Shidou to have his meal, and that meal was this sexy woman right in front of him.

Sona's hands gripped the sides of the sink as she moaned little by little, feeling the aggressive pumps from inside of her. Her eyes glanced at the kitchen as memories came back to her mind. She remembered wearing cooking attire alongside Rinne as they both smiled and giggled. Guilt and regret settled in. Yet it was also tinged with envy. But why would she need to be envious? She's a devil, is she not? Having a man who has more than one woman is practically a norm around her kind.

Sona never entertained the idea of a harem. It was quite far from her mind. Yet, right now, she could not help but think of it as she felt her rear and body shake with each powered thrust that the man behind her would give. Each strike spoke an inch of possessiveness on the part of the man, each rear shake was a submissive woman begging for more.

"More..." Sona muttered as she moaned, shaking her rear. "More... More... More..."

Shidou would aggressively try to go faster as his breathing became a little erratic. His hands squeezed Sona's breasts, eliciting a shriek from her. He wants to smash through her, inside of her, deeper.

"...Sona," Shidou muttered with subtlety, thrusting more and more. "You're becoming a little full of yourself."

"...Date...Date...Date..." Sona sported a lustful expression, begging for more as her rear shook.

Then Shidou and Sona would raise their faces to each other, raising their tongues playfully as they continued to pound into each other with mixed feelings of lust and remorse.

It all felt so good, Sona thought. Is this... Is this what Rinne felt like? Every time she made love with Shidou? Sona felt envious. It was not fair. She wanted what Rinne wanted too. It was glorious. It was giving her what she needed. Desire. Respect. Affection. This married man, who is doing this with her. She could not see him any lesser. Her rear cheeks shook with intensity as she moaned.

"...More...More, my king...More..." Sona spoke with shrieks in her tone.

"My king...?" Shidou felt like his mind snapped a little and aggressively pounded Sona again and again, making her moan. "...Then, what does that make you?"

"...Your...woman..." Sona answered as she moaned with every romp given to her by Shidou.

"Only my wife is my woman," Shidou spoke suggestively, thrusting her more and more. He would grab hold of the back portion of Sona's hair and tug it, making her face raise up a little, exclaiming with an 'Ah!'. "Again, what does that make you?"

"...Mommy," Sona muttered softly, recalling Shidou and Rinne calling each other 'papa' and 'mama', and it's because of the daughter that bore from their warm and heartfelt union.

A twisted desire sprung from her heart. She wanted that experience. Her love for children was what urged her to found her academy, Auros Academy, where everyone can attend and have the best education. She studied long and hard, she worked for that dream to come to fruition, and now she had it. All because she loved children and loved to take care of them.

"Mommy?" Shidou spoke with a growling tone, tugging Sona's hair. "So that's what you want from me? You want this? You want what I'm doing to you right now?"

"Uagh! Hai! Hai, daddy! I want it. Uaah!" Sona exclaimed a little.

Shidou let go of the woman's hair and grabbed her neck, though gently as he didn't want to hurt the woman. "But my wife is also my mommy, so what does that make you?"

"Uaah! But... I... I want it!" Sona's expression was becoming a little delirious, as lust and passion settled in. The experience was making her feel good. She didn't want this to stop. She wanted more. "...Your woman...Your mommy...I want to be that too! Make me that too, daddy! Oh, daddy~! Daddy!"

"Oh, uhgh! Mommy! Mommy! Mommy!" Shidou spoke with a growl, clenching his teeth, with heartfelt giddiness at this woman who was begging for his life-giving seed.

They pounded upon each other again and again. Sweat drops down from their skins. They could feel yet another climax approaching. It was coming to them. Just a little more. More. More. More.

"UAaaaaaaaaaah!"

"Grrrrrkkkk!"

As they climaxed, Shidou would hold on to Sona with a deep embrace, squeezing her breasts, and acting as the latter's support as she felt like she was about to fall. Both Shidou and Sona's faces were raised to the air as they panted. Sona's slender back was now lying down upon her man's torso. Shidou's embrace made Sona feel more than welcome. Drips of liquid would be moving out from Sona's interior chamber.

They would look upon each other once more and give each other a passionate kiss, playful tongues and all. Then they released each other.

"Ne, mommy?" Shidou spoke with a subtle tone. "Would you mind going down for me?"

Sona would comply as she felt her man gently lower her to the ground. She was kneeling, in a suggestive crouching position, as her mouth became dry, her eyes looking at the treasure that awaited. She was hungry for it. A curiosity and urge awakened in her. Her hand would hold Shidou's phallus and would begin to perform her magic. She would slowly make the phallus enter her mouth, making Shidou grunt a little as he felt the tempting whispering breaths. His face would look upward as he felt an exhilaration of pleasure.

Shidou would hold his woman's head and hair as the woman would move back and forth. With each slurp, she tasted the bittersweet but intoxicating flavor of fluids that had just been released. Shidou's eyes narrowed as he saw this woman be this submissive to him. At some point, he would begin to lower his hands down to his mistress's face and begin to shake it aggressively back and forth, making Sona's eyes turn upward in surprise and ecstasy.

"MMPH~! MMPH~! MMPH~!"

Sona tasted the soft hardened skin along with the crotch manly hair. She was feeling a thrilling experience as both of her hands were placed on her man's waist and embraced it. Only the thought of her man and his propagator that was slamming through her mouth remained, one of thrilling ecstasy, and her mouth was consuming the sweat that lay underneath. It just felt so good, she thought, like there was nothing except clouds that occupied her mind that remained ecstatic as she vigorously moved her face back and forth even as her man was aggressively moving her face to spark her man's inner bestial excitement.

Using her devil magic, conjuring up the element of ice, Sona would provide her man with a heightened experience of ecstasy, feeling the light cold breath that would suck through his intromittent organ. Shidou continued to thrust into his woman's mouth with more vigor. He never felt so alive at this moment. When he does this with Rinne, he always needs to be careful. But with Sona, he did not need to hold back whatsoever. Hence, the aggressive approach, yet moderated.

Then they continued the thrust deeper and deeper, with Shidou feeling the reverberations of his woman's muffled voice, until he released his erection fluids deep inside Sona's face shining with ecstasy and thrill. With no time to waste, Sona would clean up her man's reproductive organ with loyal and lustful affection mixed together.

Shidou smirked from the inside. This woman, known for her professionalism and cool beauty, was now in this state of lust and passion. He can see his woman pleasuring herself, desiring to continue sucking whatever she might consume and inhale the intoxicating aura and odor that would make her instincts driven to new heights of desire and passion.

And Sona consumed it. Every last drop.

"...Mama."

Somewhere in the bedroom, there was Rio and Rinne who were lying on the bed. Rio would speak softly, awakening a little, with Rinne sporting a sweet smile as she patted her daughter's hair.

"What, Rio?" Rinne asks.

"Where's...Where's papa?" Rio asks a little.

Rinne's smile would turn sad a little. Her expression seems to indicate that she knows something. "Papa's a little busy, Rio. He's helping Sona-sensei out right now, so he won't be joining us in bed tonight."

"...Is that so? But..." Rio muttered softly, cuddling her face to her mother's bosom. "I want papa to be here with us."

"Oh, Rio, papa would always be here with us," Rinne spoke with a kind smile as she continued to pat her daughter's hair. "His heart would always be with us. I'm sure of it. Even if..." She did not finish the last part, making her sentence felt incomplete.

"Even if...?" Rio asks a little, muttering as her eyes closed.

"Hmhm, it's nothing," Rinne embraced Rio, not wanting to explain more, with the latter being her comfort for this night. "Ne... Rio..."

"Hmm?" Rio hummed.

"...Do you. Do you want... another mama..?" Rinne asks with a considerate, sweet tone.

"...Hmm? Another mama?" Rio muttered softly.

"...Hmm. So... who do you want for your mama... besides me of course..." Rinne asks.

"...I... I don't know..." Rio muttered. "...Aren't you the only mama I have, mama?"

"Hai, and I will always be your mama, but..." Rinne's smile would be a little sad. "...Say, your papa would want to choose for another mama, who would you like it to be?"

"...Hmm," Rio, even as her eyes closed, would think for a bit. Then. "...Sona-sensei."

Rinne's face looked a little sad yet was not surprised. "...Why?"

"Sona-sensei is... she's a nice person... She... She helps me out with my studies... She teaches me many good and wonderful things. She gives me treats when I'm a good girl. We always have fun together when we hang out, showing me places and explaining them to me. That's... That's who I would choose... as my other mama."

Rinne gently patted Rio's hair with a smile. "...Is that so?" She muttered while sighing a little, closing her eyes.

"Hmmm~..."

Now was time for another passionate round. Somewhere in the residence was the locked room of a private shower. Fresh clothes, conjured by devil magic, were seen folded just near the sink. Fresh towels were leisurely hanging on the metal rack on the wall, ready for use. Sounds of running water echoed as hot steam billowed out from beyond the glass door, with two distinct silhouettes seen melding into an embrace within the shower room.

As droplets of warm water rained down upon him, Shidou savored the sweet, soothing taste of Sona's luscious lips as the duo both explored each other's mouths. Their tongues danced and glided around one another, surveying every nook and cranny as Shidou gazed into her beautiful violet eyes, no longer obscured by her glasses. Her pure white face and long black hair glistened and gleamed under the running shower, causing his instincts to stir as he pulled her deeper into himself, with Sona moaning hungrily in response.

As Sona returned his embrace, with her modest and perky breasts pushing against his firm chest, Shidou felt his heart throb with a whirlpool of carnal emotions as he used his tongue to further dominate his...

...His mistress.

There was no other way to say it. Shidou now has a mistress, the one whom he was committing a conjugal act of sin with. His embrace was Sona's own delight. The blue-haired man could already feel something underneath hardening, its thick mass straightening to a point as it gently brushed under Sona's warm, moist folds. The urge, the need to ravage her again was overwhelming, causing the pair to briefly release themselves from their liplock. Hot, ragged gasps escaped their lips before they smashed into each other once again, their tongues eagerly continuing the lustful tango as the shower continued to cascade down on their bodies.

The combined warmth from both his mistress and the shower slowly, but surely washed away all of his anxieties. At this moment, nothing else mattered; All his thoughts and feelings were focused on the devilishly gorgeous woman before him, who was gladly providing him with the most pleasurable comfort that she could offer him to the best of her abilities. The urge and raw desire within him grew stronger with each passing minute. They hadn't even begun to well and truly make love, and yet the sheer heat of their privates rubbing together along with the warm water streaming down upon their faces had left him intoxicated.

The need to breathe now was far too great, Shidou and Sona pulled away from their session as they sucked in as much air as they could, all the while gazing at each-others eyes withing nothing but love and need. His eyes went downward, staring unto her marvelous twin peaks, his already short breath taken away at the sight. Then, without warning, Shidou opened his mouth and hungrily clasped onto Sona's left breast, all but devouring her nipple and areola.

"Uahhh~!" Sona gasped, the feeling of electricity ran down her spine as Shidou suckled onto her delicate breast, causing her to close her eyes shut and place her hands upon her man's wet hair. The temperature around them began to feel both hot and cold as Shidou lost himself within his own ministrations, pushing away any anxious thoughts that would dare sneak back into his head. Soon, he removed his lips from her now erect nipple and moved to the nape of her neck, eliciting another pleasurable moan from Sona as the water dripped from her face.

They were taking things much slower than usual, savoring the moment as Shidou felt his heir reach full-mast, his instincts clamoring him to thrust inside Sona's devilish interior; to take her and have her bear as many children as she could.

... But he cannot do so. Not yet. The time was not yet nigh.

Feeling a warm breath brush past his ear, he released his lips from Sona's neck to see her slowly and suggestively moving up and down, dancing for him as her own hands scoured his well-built frame. A very impressionable scene that would make him feel all the more loved and desired, feeling each touch and kiss she herself placed upon him send shivers down his spine. From his Adam's apple, to his upper and lower torso, to his broad back and shoulders as he feels the faint touch and whispering words of his wife drawing him in.

With each gentle caress, Sona was enjoying the toned muscles of her loving husband, playfully examining every inch for herself in glee that borders on predatorial. As her hands moved smoothly up and down, her body swaying to and fro, maintaining contact with her man's muscular body, she couldn't help being so frisky. In her mind and body, all that mattered to her right now was her man, nothing more. She released her own machinations, drawing out this passionate, yet somber moment for as long as she could.

By the time Sona finished another turn, Shidou had already grabbed onto her waist and given her another wide-open passionate kiss, the thrill and exhilaration of it all left her moaning as her husband devoured her lips once more. The steam from the shower began to build up in the shower, obscuring their vision as water dripped from their skin. The urge to become one was growing ever stronger, and before they knew it-

"...~!"

Sona released a soft moan as she felt Shidou entering into her in a single motion, holding onto her man's head with trembling fingers. Her heartbeat thundering in her chest, her breath becoming more hot and erratic as she felt her husband's burning manhood fill her insides as they continued their deep, passionate kiss, tasting both their sweet lips and the dripping waters of the shower all the while. As she felt her husband lifting her up by her hips, she would wrap her legs around her man's waist, locking them together nice and tight.

With slow, measured movements, the two lovers finally began in earnest, rocking their bodies in tandem as they drowned themselves within one another, allowing their bodies, hearts and souls to meld into one. Their bodies swayed to and fro; Shidou thrusting his hips forward in sync with Sona bucking as their lips desperately clung to one another, never letting go of their deeply immersive kiss which was accompanied by the running water that came down like the rain.

With every move the husband and his mistress had made, their enjoyment of each other's bodies rose as they released themselves from their lovely make-out session, gasping for air. Every nerve in their bodies was screaming in ecstasy, the sheer rapture of it all went up to their brains as they cherished each other's warmth. Letting their love and passion guide their movements, they both increased the speed and tempo accordingly as the sounds of flesh smacking into one another began echoing throughout.

"Muahh~! Ahh~! Ahh~! Aghh~! Ah! Ah! Ah! Ah!"

Shidou gritted his teeth as he felt his mistress's hips slamming further down unto his dignity, her pleasurable moans resounding in his ears and encouraging him to penetrate further into her cervix as the water continued to rain down on them. He brought his hungry lips towards Sona's once more, the latter fully melting into it as they went on into their love-making.

"...Sorry, Rinne," Shidou muttered softly, feeling guilty amidst the bountiful waves of pleasure he was receiving, almost like it was a wet dream coming to life.

"...Uaah~!" Sona widened her eyes a little. Rinne's name made Sona smack down her hips faster, making Shidou grit his teeth as he followed her volatile movements.

They lost count of how many hours had passed. Each of them was hungrily devouring each other's lips. His hands still held a firm grip on his mistress's hips as he continued to thrust into her, the head of his anchor pressing deep against her womb which was sending waves of pleasure throughout her body every time. At that moment, Shidou felt like the man in the house, as he dominated this woman right in front of him, joined together.

He was making love with another woman. That thought made him question his sanity at this point. Never in his life would he imagine doing this kind of intimacy with anyone but Rinne, his beloved wife. And yet, Sona managed to succeed in making him do this. Months of frustration and tension were now being released inside him and pumping them straight ahead into this woman, smacking his waist more and more.

But even so... he was troubled...

"Daddy~... Ah... Nhh... You're troubled..." Sona muttered as she placed her hand on his wet cheek and peered into his eyes, her own heart weighing heavy on her chest as it continued to flutter. Even as he continues to give her his love and care, his lust and passion, she can see all too well the worry that plagues him as she swings her hips just for him, offering her all to soothe his fears. She was having fears too.

"...Rinne...Rinne might notice us..." Shidou muttered in remorse despite continuing to indulge in Sona's body, focusing all of his energy on holding the coming climax that was now erupting inside of him. Not yet, he thought. Not yet.

"Hmm..." With an understanding hum, Sona draped her arms around his shoulders as she gave him a brief, yet passionate kiss. "I... I wouldn't worry..." Sona spoke with ragged breaths. "...Just focus on here and now. Give me everything, daddy. I want... I want to take all of your worries away... Ah~!" She said while shaking her hips and grinding them up and down, her perky voluptuous breasts were bouncing and entrancing Shidou at the same time.

"But-Hmph~!" Just as Shidou was about to protest, Sona silenced him with her mouth, twisting his tongue with her own and entwining them together.

Before long, she released their tongues from their dance as she continued "Do not... worry... daddy~... Just... Just let go... Focus on me...Focus on giving me...what you give to Rinne."

What he had given to Rinne? There was only one specific thing that came to mind. Something in the back of Shidou's mind snapped as the realization settled in.

With the many times Shidou had done with Rinne, the moments of pure, genuine intimacy, allowing them to show their wants and desires, showcasing what they are with one another. How many times have they done this? How many times since they have been wed has Shidou buried his thick seed deep inside Rinne's needy womb? He had honestly lost count by this point, but no doubt they were all very pleasurable experiences.

A new twisted desire has now sparked in his chest, one that quickly grew into a raging flame. A desire not of pleasure... but of procreation.

"Ahh... Ahh... Da-?"

With that desire now burning within him like a raging inferno, he began to swing his hips with reckless abandon.

"AUGH~! AUGH~! AUGH~! AUGH~! AUGH~! AUGH~!"

A twisted desire. To have a child with Sona. To impregnate her. He's already tried to do that two times. First in the living room. Then in the kitchen. Now it was the private bathroom. A part of him felt guilty for even thinking about this kind of thing. He already has Rinne and Rio. And yet, doing it with another woman brought him a new kind of pleasure. A thought of him wondered. Would Rinne accept Sona as Shidou's woman? Maybe even a second wife? Maybe even a second mother for Rio? Those were the thoughts that crept into his mind.

But, from what he recalled, Sona was a pure-blooded devil, therefore, the possibility of having a child with Sona was almost zero. That would both miffed and relieve him. More so with being miffed. Twistedly, he thought that giving his daughter Rio a younger sibling made Shidou became more eager and cheerful than usual.

"...Ne," Shidou gritted his teeth, his tone felt like the growl of an alpha lion. "What do you think of Rio, mommy?"

"I... uaah~..." Sona struggled to utter with her tongue hanging out and her moans slowly devolving into shrieks of ecstasy, her hips continued to sway back and forth through Shidou's thrusting. The showering water now has become lukewarm compared to the scorching heat from their bodies, feeling nicely cool against their skin as it continued to rain down. Her violet eyes would glow with a luminescent effect, showing her desire for more as she continued. "I think that she's... she's a wonderful and... intelligent child. She takes after... her papa... in kindness..."

"Mama..." Shidou muttered, thrusting hard and fast. "...Would you... Would you like to be Rio's mother?"

Sona widened her eyes as she felt smacks coming down upon her, with shrieks and moans, wondering about the rather bold question that she was given. "...But... Rinne..."

"...I," Shidou spoke as he thrusted inside Sona more and more. "...I don't... I don't want to keep this... a secret from Rinne forever... I couldn't... I don't want her to... hate me..."

"...She'll," Sona muttered, her eyes brightening. "She'll never hate you. She... loves you, daddy. I can... I can see it..."

"But... she'll... she'll be heartbroken..." Shidou spoke with a contrite tone even amidst her thrusts.

Then Shidou would feel the passionate twisted tongue from his mistress, entwining them, before she released her tongue.

"Then... we'll... We'll bear this sin... together, daddy~! Whatever you... want to do... I will follow your lead..." Sona muttered with a reassuring tone, bittersweet amidst the running pleasures that cultivate within the two of them. Then a moment of contrition was mixed within the pleasurable moans. "...But... Hai... I... I do want... I want to be Rio's mother... too... Does... Does that make me selfish...?"

"No..." Shidou shook his head "No... you're not..." He gritted his teeth, his movements grew more primal as he went deeper and penetrated through her cervix and into her womb, sending an explosion of euphoria throughout Sona's body.

"I... I see..." Sona muttered, the burden within her heart began to vanish as a feeling of endless bliss washed down on her like a tidal wave.

Then Shidou would smash his mouth with Sona's, making her drive her hips even faster. Then he drew his mouth away from Sona's mouth, speaking firmly as they both swayed against each other. "...I'll. I'll take responsibility."

"Da...Daddy.." Sona muttered softly, feeling ecstatic happiness and pleasure. She could not care less if Shidou was a married man or even if he has a child, she felt the most fortunate devil alive by being given this rare price that she would treasure inside herself. He wants her, with all of his heart, body, and soul. No other man could compare. Shidou Itsuka was the desire of her heart.

"I won't... let you go... I want you to be beside me... I want you to be my woman... my mistress... and someday... my wife. I want you to be alongside Rinne as my wife. I want you to not just be Rio's sensei... but as her mother... And... I want a child with you... too..." Shidou spoke with honesty, feeling his girth expanding and his growing orgasm fast approaching.

As he hastened his thrusts, he could see Sona's face showing a full flurry of emotions, ranging from shock, joy, love, and lust. Brown eyes narrowed and violet eyes flashed, feeling they were each close to climaxing, they drew their mouths close and kissed as they both rapidly slammed their hips against each other.

"HMPH~! HMPH~! HMPH~! HMPH~! HMPH~! HMPH~! HMPH~! HMPH~! HMPH~! HMPH~! HMPH~! HMPH~! HMPH~! HMPH~! HMPH~! HMPH~! HMPH~! HMPH~! HMPH~!"

And then, at the very peak of nirvana, the two of them crashed into one another with all their might-

"HMMMMMMMMMMMMMMMMMMMMMMMMMMMMMMMMMMMMMMMMMMMMMMMMMMMM~~!"

Their bodies shake violently as they both orgasm, with Sona's love juices spilling over their hips and legs as Shidou shoots ropes upon ropes deep inside Sona's aching womb. Even as he continued to unload his seed inside her, Shidou was still standing firm as he carried Sona's quaking body. They both breathed and gasped as they were slowly brought down from their high, their brightly colored eyes locking into each other.

"Hmmm..."

They then continued kissing, though this time much more gentle and chaste. Even as they felt the shower raining down upon them, washing away their fluids, they remained still, connected, and content to stay in this position for a little while longer. All the while, he felt his mistress's heartbeat thumping against her chest as she pressed into him, their two hearts now beating as one.

Shidou's mind felt a bit refreshed, having just found some semblance of peace after venting out all of his frustrations. Granted, his troubles and worries were far from over, but right now, he was merely content to enjoy this very moment with Sona, with his mistress.

He won't give her up, not ever. He will try to take responsibility for this. He may not tell Rinne now of what he'd done together with Sona, but he would need to tell her eventually. A conflicting desire to want to be honest with Rinne and yet at the same time not want to hurt her heart, not after everything Shidou and Rinne had been through together. Until then, he wants this. He does not care if some may try to oppose his relationship with Sona.

He will try to face all of this.

As a Man. As a Husband. As a Father.
