After those passionate hours of the night, things weren't the same.

It was sometime a little before the early morning. The entire Itsuka Residence exuded a sense of general awkwardness.

Shidou, having just woken up, and had a little difficulty sleeping, from a bed that was found somewhere in his office room, somewhere on the first floor, was now in deep and reflective thought. A common thought was circulating in his mind. He... He just made love with another woman besides his wife. Sona Sitri.

Right now, she was probably somewhere back in the living room where, as a way to maybe take her mind off of things, would focus on watching television, until she'd probably fall asleep. It was a good idea right now to be separated from her after... what he just did with her. Releasing all of that tension that had accumulated from the months of knowing about her. The memory of her being pounded by him, the way her figure jumped up and down for him, it was... ...it was an amazing yet intoxicating experience. Quite addictive and sensual. Sona really was a devil.

Shidou was surprised at just how much of an... expert Sona was when it came to sex. But should he be surprised? She's a devil after all. There was also... the way they had sex. It was nothing compared to what he had with Rinne. With Rinne, Shidou felt calmer and careful. He wanted to embrace Rinne as he did it. He wanted to make her feel loved and comforted. When Shidou does it with Rinne, it's like he is basking in the heavenly clouds, content with things in a peaceful manner, a relief after a hard day's work.

With Sona... Shidou shivered. It was a whole new kind of experience. Indescribable. He felt guilty, yet he could not help but relish and indulge in it.

He sighed a bit. He wondered just what he was supposed to do now.

After deliberating a little, he stood up from his seat and intended to meet with Sona in the living room again. He could not get Sona out of his mind. What he and she had just recently shared. It was not something that just went away. Even now, he felt the urge to gravitate towards her. This was an entirely new experience for Shidou. It was something that never really happened before. He's met plenty of beautiful women, and that's mostly in relation to the Spirits that he managed to seal, who were now living their own lives in the world.

He went towards the living room and would see Sona, having muted the volume of the television with the remote. Perhaps she wasn't in the mood for watching television.

Her face felt a little pale, with a somewhat lack of sleep on her part, which accentuated her mesmerizing beauty from Shidou's point of view. His heart ached. Memories of his experiences with Sona as they made love to one another were fresh from his mind. Her soft white skin. Her luscious lips. Her slithering tongue. Her ample bosoms that awaited to be devoured and sucked. It was a wonder that Shidou had managed to last this long, controlling himself until he finally gave in.

There was guilt and regret within his heart. No doubt Sona felt the same, but perhaps even more so. Rinne was her closest friend after all. He could tell how close they were over the months that had passed by.

He would call her name. "Sona." Which in turn sends the black-haired beauty looking at him in shock.

"Sh...Shidou..." Sona muttered softly. Her expression was pale, her violet eyes were filled with uncertainty and regret.

"...Do you mind if I sit down beside you?" Shidou asks.

"...Hmm," Sona slowly nodded, but her expression seemed to be dreading the prospect.

Shidou would slowly walk towards the sofa and sit beside Sona, closer than the norm. Shidou placed his fingers together, clenched and cold. He looked Sona directly in the eye and said. "It wasn't a mistake."

Sona widened her eyes a little. Then she noticed Shidou's left hand placing itself to her side and dragging her body towards him in an embrace.

"...I ...I love Rinne. I love my wife. And I love our daughter, Rio. I love them both and I don't want to betray them. I... I promised that ever since I got Rinne and Rio back again in my life, I wanted to be the best husband and father that I could be for them. But..."

Shidou looked crestfallen, making Sona's heart jump with empathy for the man while a tinge of regret lingered within her own as she felt like she was the cause of this.

"...Now I'm asking myself, how can I be the best husband and father when I... I have feelings for you, Sona."

"...Shidou," Sona muttered, her violet eyes glowing softly.

"I know it isn't right, what we did. But... I don't consider what we did as a mistake. I can't. Because I..." Shidou muttered, but Sona would cut him off with one index finger raised to his lips.

"No need to finish it. I know what you mean," Sona made a sad expression when speaking. "But I..."

Shidou would hold Sona's hand, which included her index finger. "I want to continue this." He declared, making Sona shocked at such a declaration. "I want to continue what we have. I can't turn back anymore, not after what we did. I... I need you to hear this out, as I am right now. I love you, Sona Sitri."

Sona's heart was touched to the core. A part of her whispers no more. She had done enough. She had already sullied herself as a potential homewrecker by having sex with a married man. It was too much.

"Maybe this is selfish on my part and I may even sound like an unrepentant cheating bastard, but I truly and deeply love you, Sona. I want you to be a part of my life, just as my family is a part of my life. I want you to stay by my side and love me as I love you. I want to make love with you for as long as you and I live. I want you as my woman, and no one else's. I loved your looks, I love your charms, I love the way you handle things, I love how smart you are, I love how you always try your best even when you fail a lot, I love how you always have my daughter's best interest at heart and taught her many things, I loved everything about you, Sona, and... I don't want to lose you."

Sona's eyes felt like they were leaking tears. Her hands were moving towards the man's chest, placing it on the latter. She bit her lip, giving her a cute pout expression.

"You... You idiot. Do you have any idea what you're trying to say here?" Sona could not help but ask with trembling lips.

"I do," Shidou spoke with resolve.

"Shidou, I may be a devil who had come from a culture where a man can have more than one woman, but... you are not a devil, and neither do you or Rinne follow the norms of our culture. Even so, by all rights, I am but a mistress, which is doomed to be second best only to the true wife. That's..."

"You're not second," Shidou spoke, attacking head-on. "Not to me. You and Rinne are my number one women. Only you two. No one else."

"But... the math doesn't work. How would you try to love both me and Rinne at the same time?" Sona asks.

"Don't you know, one plus one equals two," Shidou answered.

"How does that work in light of our situation?" Sona asks again.

"I'll make it work," Shidou said.

"But ho-Hmph!"

Sona's words were cut off as Shidou launched his lips to hers, initiating a deep passionate kiss. Sona's lingering thoughts of trying to get him off would dissipate as her mind evaporated with the kiss and accepted it slowly. They embraced each other deeply. Shidou would drag Sona's body towards his, making Sona form a sitting position towards his front waist. With tongues twisting and turning, as their faces turn left and right, they let go of their kiss. Sona's expression was turning a little sultry again, with her face being complimented by tears.

"That's how I'll make it work," Shidou said. "I... I want to eventually tell Rinne about our relationship, but... before that, I'd like that we'd keep it a secret for now, because I need to think of what I need to say first, and I'd probably ask you to maybe help me with that. Is that okay?"

"...H...Hmm," Sona slowly nodded. She felt her tears being wiped away by Shidou's hands.

They initiated yet another passionate kiss before they were released.

"...I should probably make breakfast for everyone right now, since it won't be long before the sun rises. But..." Shidou spoke as his eyes narrowed a little, putting a hand on Sona's cheek. "...I want to try something with you at the same time."

Right now, Shidou was currently cooking eggs on the frying pan. At the same time...

"...umm. umm. aum."

Shidou was having breakfast of his own, of a different kind. Having removed Sona's panties a little, Shidou had once again inserted his manhood deep inside Sona's vulva, with the latter's skirt providing the cover of their intimate union. Sona was currently holding onto the sides of the sink. Right now, he was multi-tasking, on the one hand, savoring these rare moments with his new mistress while on the other hand, he maintained some level of focus on what he was cooking.

He never really tried this kind of thing before with Rinne, now that he thought about it. His intimate moments with Rinne are for the most part on the normal side of things. Since they only had a few moments at most before Rinne and Rio woke up, Shidou wanted to make everything count while at the same time wanting to keep his woman's moans quiet, hence holding her mouth with one of his hands.

He struck through his mistress with renewed vigor, savoring each stroke, making the latter moan a little in pleasure. His other hand was holding the spatula that would allow for the turning of the boiled eggs. Shidou let his hand go a little from Sona's mouth, placing it on her stomach, making surprisingly deep strokes that made Sona's rear grind his crotch. She bit her lips a little, controlling her moans and not wanting to erupt.

As a way to showcase his resolve, Shidou would make love with Sona. Actions speak louder than words in this case. This was the second time Shidou was having sex with Sona in the kitchen, and it just turned him on so much. Sona was more or less the same, feeling the sense of being a naughty woman who was making love with a married man. She shouldn't even enjoy such a thing, and yet here she was, clearly enjoying it.

"...Ne, my queen, am I making you feel good?" Shidou asks a little, thrusting with everything he's got.

"...Hmm, yes, it feels... it feels so good, my king," Sona's mind became lost in exhilarating ecstasy. Even so, she somehow manages to keep a steady voice and control her moans a little. Sona, at some point during the multiple thrusts that allowed her to experience euphoria, would say carefully, showing a hint of trepidation mixed with pleasure. "...My king, what... what if we get caught?"

"We won't..." Shidou spoke with a soft growl, thrusting hard. "Just focus on me, my queen, on me. Or... do you want us to get caught?"

Sona muttered weakly, shaking her rear "...N...No."

"But you seem rather excited right now, my queen?" Shidou spoke with a suggestive tone.

"Date... Date... Date..." Sona spoke, shaking her rear, begging for more.

Then Shidou and Sona would perform a passionate, playful kiss, with tongues twisting a little before releasing, as their momentum and tempo increased. The noise of the fried eggs and its smell carried a kind of sensual atmosphere that, if Shidou and Sona didn't know any better, was something that's only found in Issei Hyoudou's porn stash. And to think that back in the day, Sona was one of those individuals who were scolding Hyoudou and his two friends from the Perverted Trio for such indecency.

Sona felt like a hypocrite at this point, because she was still making love with a married man, the man she loved and lusted for. For most of her life, she was the dominant one. She was the woman who would not willingly submit. And yet, here she was, being given the best rear sex that she could not even imagine until now. Shidou respected her figure, making the experience tender despite the aggressiveness. In a word, Shidou made her feel loved. She does not want to part from this experience. She wants to continue on.

Forgive me, Rinne, but I cannot deny it anymore. I love your man, as much as you love him. I want what you have. Forgive me. Sona thought.

They continued pumping on and on as the eggs boiled to become edible. Sona tried hard to hold off her moans, grinding her rear up and down the manhood that was now dominating her body and soul. She felt her mouth being held by Shidou again as he quickened the pace of his thrusts, making Sona shriek a little.

"...Sorry, Sona, but I need... to end this quickly," Shidou spoke with a whispering tone. He was checking the time of the clock that was nearby. It was almost six in the morning. He needed to end this quickly and initiate a climax. He thrusts hard, faster and faster, as Sona's mind turns blank and putty, instinctively grinding her rear up and down her man.

"HMM~! HUM~! HMP~!" Sona's muffled sounds were heard a little, covered by Shidou's mouth to prevent them from leaking. Shidou gritted his teeth with every strike that he pounded deep inside Sona.

And then...

"HMMMMMMMMM~!"

A climax occurred. Fluids would conjure up and fill Sona's empty womb. Shidou gritted his teeth as he felt Sona's lips vibrate from her muffled shrieks, as her violet eyes suggestively looked up. Yet another satisfying release. After letting his hand go from Sona's mouth, Shidou would make sure to keep the stove warm, making it lose its heat as the eggs were ready. Then he embraced his mistress, his queen, his devil who was now sporting a satisfied expression.

He felt her hand placed to his face as she moved the latter towards her own, and made a soft, touching kiss, as a reward for giving her such satisfaction.

"...I'll never let you go, Sona," Shidou declared softly. "You're mine, now, and always will be, understand?"

"...Hai, my king, I am yours," Sona spoke with a soft, touching smile, grazing his cheek with her fingers. "I am yours to do as you see fit."

"...Good," Shidou spoke. "And my first order as your king is that... we continue to have these moments together, is that alright?"

"Hmm..." Sona softly hummed with a satisfied sultry smile.

Then he and Sona made a passionate soft kiss once more, as the former's manhood still remained within the latter's interior chamber, culminating in a warm embrace, and lighter, suggestive momentum of their bodies.

Rinne would slowly wake up from the bed.

There was no sign of Shidou anywhere. Just their daughter Rio who was sleeping soundly. Rinne's heart suddenly felt a tinge of sadness. Where was Shidou? Where was her husband? But some part of her already knew the answer to that. No, one part of her was denied. Her husband was only faithful to her. He loved her and she knew it. And yet, some part of her doubted it.

After making sure that Rio was still asleep, she would walk towards the door and head downstairs. She did not see Sona anywhere, nor Shidou. She smelled something from the kitchen, probably someone cooking.

Rinne would walk towards the kitchen, passing an overarching path to find Shidou busy cooking eggs, with Sona simply opting to observe professionally, putting her hand to the bridges of her glasses.

"Oh, papa, Sona-chan, good morning," Rinne smiled, making the two pay attention. Was it out of relief? Was it out of worry? She did not know. But nevertheless, it seemed like nothing had happened. Or did it? The only thing that Rinne noted was... how tired Shidou looked. That worried her a bit. She even glanced at Sona and she could see a little tiredness present in her eyes. Did something happen last night?

"Ah, mama," Shidou smiled a little, and he would see Rinne coming towards him and giving him a soft peck on the lips. Somewhere on the side, Sona looked... a little sad and guilty when that happened. "Good that you're awake. I'm cooking eggs right now. Thought I'd make something special out of it for all of us to eat."

"Hmm, I can't help but be excited, considering my husband is rather a good cook, ne, Sona?" Rinne asks with a cheerful smile, looking at Sona, who smiles a little.

"Hmm." Sona hummed in a positive. But the guilt and regret still settled in. Now she was diving headfirst into a place with no return. An affair with a married man. She could not help but hate herself right now, and yet, there was no place she'd rather not be, in order for her to stay by the side of the man that she could not help but love and lust for. A walking contradiction. A forbidden love. It was something that she never thought to entertain. And yet, here she was.

Sona instinctively touched her stomach, as if trying to feel the remaining fruitful seeds that were still embedded into her womb. Her eyes lowered a little.

"Sona-chan," Rinne spoke, noticing Sona being rather quiet.

"Hmm? What is it, Rinne?" Sona spoke, being attentive.

"Hmhm, nothing," Rinne shakes her head a little.

Rinne did not know why but... there was something odd that she was feeling right now. Maybe this was just her imagination, one part of her thought. Nothing happened, she thought. Nothing happened. But even Rinne was unsure about these thoughts.
