'Little brother~❤️ Slurp~ Slurp~ Do you want to let it all out?!'

As those playful, flirty words echoed in his mind in a familiar voice, Seir's gaze fell upon the mature, cherry blossom-haired woman kneeling before him with her body bound with ropes in an intricate Hishi Karada bondage, her flushed face with embarrassment, shame, and excitement, tilted upward, and her eyes meeting his as her tongue worked diligently on his cock.

In that moment, as he looked at his elder sister, who has always been a graceful and poised figure, the only thought that crossed his mind was, 'I really do…'

'Fufu~ Leave it to your elder sister… Just with this mouth of mine, I'll have you cumming in no time…'

'Mm~' Seir groaned in pleasure, but just a moment later, a gentle and composed voice—familiar, yet different from the one that had been whispering to him a moment ago—interrupted his bliss. "Lord Seirios…"

"Lord Seirios… It's time to wake up."

Immediately, all the pleasurable sensations vanished, and the boy shifted groggily beneath the blanket, grumbling in a thick, sleepy voice, "Mmm… Zest… You could have waited a few more minutes… I was so close…"

Zest tilted her head in confusion. "Close to what?"

"Nothing, just sleep talking…" Seir muttered with a sigh, dismissing the topic without further explanation.

"…Alright?" Zest responded after a brief pause before shifting her attention back on the main matter, "You should get up, Lord Seirios. I've prepared the tea."

"I see… Yawn~" Seir murmured as he let out a yawn, lazily pushing himself up until his back rested against the bed.

Zest picked up the porcelain cup from the tray on the nightstand and handed it to him. "Here you go. This should help you wake up."

"Hm…" Seir hummed as he took the cup, while Zest moved to the windows, pulling back the curtains to let more light flood into the room.

Taking a sip of the lukewarm tea, Seir sighed in satisfaction. 'Nice…'

Then, turning to the maid, he requested her, "Zest, can you prepare a bath for me?"

"As you wish," she nodded, heading toward the bathroom.

"Cold water… please," Seir added from behind.

Zest paused briefly, immediately understanding the reason behind Seir's request for a cold bath over a hot one. 'Today too…?' she wondered before nodding once more. "I understand…"

As Zest left, Seir took another sip of tea while slipping his left hand under the blanket to brush over his crotch through his sleepwear. 'Yeah… today as well, it's there…' he sighed internally.

It had been three days since he started living in this castle, and ever since Maria used her Succubus Magic to make him watch that wet dream on the first night, he had been having similar ones every night. While the intensity of stimulation in the subsequent dreams wasn't as overwhelming as the first—since he wasn't experiencing nocturnal emissions every night—the effect still lingered, causing him to wake up with morning wood every single day.

It's like a switch had been flipped inside him, leaving his body and mind constantly restless.

"Damn it, Maria… this has become a daily occurrence because of you," Seir muttered, feeling the urge to storm into her room unannounced and give that troublesome succubus a thousand well-deserved spankings for what she had done. But he stopped himself from doing that because he knew all too well that spanking her would only make her enjoy it and likely want more.

'And that Red Room of hers…' Seir didn't even know what to think about that place. He wanted to erase it from his mind, but of course, that was impossible. It was affecting him more than he cared to admit, something made painfully clear by the dream he had had today.

'Roygun… tied up like that?' The thought surfaced before he could stop it. 'If I'm being honest, I wouldn't mind seeing her like that in reality at least once…'

Realizing what he was thinking, Seir quickly shook his head, trying to push the thought away, and let out a heavy sigh. 'Let's just focus on the tea for now…'

Bringing the cup to his lips, he attempted to drown out the lingering images in his mind, but they refused to fade. No matter how hard he tried, they clung to him stubbornly, making his frustration boil over as he muttered under his breath, "Shit…"

"Lord Seirios? What's the matter?" Zest, who had just walked back into the room, noticed him cursing under his breath and asked with concern, "Is something bothering you?"

"Hm? Nothing…" Seir replied, shaking his head before changing the subject. "Is the bath ready?"

"Yes," Zest nodded.

"Alright…" he murmured, placing the empty teacup back on the nightstand before rising from the bed. As he made his way to the bathroom, he added, "Thanks," acknowledging her efforts.

Zest hesitated for a moment, biting her lip before softly calling out from behind, "Shall I… assist you?"

Seir paused mid-step. "Hm? Assist?" he asked. "With the bath?"

After a brief silence, Zest nodded. "Yes…"

Seir hesitated for a moment, contemplating whether to accept her help with the bath. 'Élise was the one who always bathed me before… I've been refusing Zest on this, but maybe…' For a brief moment, he considered accepting, but then—'Ugh… but if her hands touch me, it'll only make things difficult… Yeah, let's not…'

With that thought, he shook his head. "I think I'll be fine on my own…" And before she could say anything more, he stepped into the bathroom and shut the door behind him.

Left alone in the room, Zest stood still for a moment before making her way to the wardrobe, selecting the clothes Seir would be wearing for the day.

As her hands moved with practiced ease, her mind was anything but idle. 'It seems Lord Seirios is growing more and more frustrated from his pent-up arousal…'

It was clear to her that he was making a strong effort to restrain himself. The daily cold baths were direct evidence of this—his way of trying to suppress his urges and regain control.

But the problem was that cold baths were only a temporary solution, and it was clear that the strain of holding back was taking a toll on him. He had been zoning out quite frequently, and his ability to focus had noticeably declined.

'Should I help Lord Seirios with this?' she wondered. She didn't like seeing the troubled look on his face and wanted to assist him if she could. However, something held her back. 'Would Lord Seirios even accept my help?'

Then, there was another concern. 'How would Mistress react if she found out?' Even if her intentions were purely to help Seir with his problem, the fact remained—she would be doing something questionable to her master's younger brother behind her back.

She contemplated the matter for a while before coming to a decision. "I should inform Mistress and let her decide. If she orders me to, then I shall assist Lord Seirios in relieving his pent-up desires."

With that decision made, she resolved not to keep the matter from Roygun any longer.

.

.

At the breakfast table, the atmosphere was undeniably awkward, and everyone could feel it.

The reason? Seir was actively avoiding eye contact with Roygun and refraining from engaging in any conversation with her.

Of course, he had his reasons. 'I really can't look at her directly without picturing her in those bondage situations…'

After all, he had been having vivid, very vivid dreams about her—dreams that refused to fade from his memory. Every time he glanced at her, those scenes only became clearer, forcing him to avert his gaze and sigh in frustration.

'Damn it… Even if I was a horny guy in my past life, I was never this bad. Sure, I had wet dreams, but it never got to this point… What the hell is wrong with me? Is this my true nature? Or is this happening because I'm part Incubus?'

That had to be the only explanation—nothing else made sense to him.

Devils were creatures that indulged in their desires above all else, and Incubi… well, they practically lived and breathed debauchery.

Because his body has experienced that sensation once—even if not in the way he would have desired—it's only natural that it craves it again. As a result, his Incubus instincts are screaming for him to indulge in that forbidden pleasure.

'Do I really need to have sex with Roygun to calm myself down?'

'I mean… it's not like I don't want to… but how would I even go about doing something like that?' It's one thing to desire your older sister, and want to fuck her, but acting on it is an entirely different matter.

'Even if we're devils and incest isn't that big of a deal for us… still…'

'It's not like I can just ask her, and she'll spread her legs for me…'

'Maybe someone other than Roygun… but who should I ask to willingly offer themselves to me so that I can fuck them?'

'On that note… how do you even go about fucking anyone?'

He didn't have an answer… if he had one, he wouldn't have remained a virgin in his previous life.

'Do I have to learn the art of seduction?'

'But… there's another way, isn't there? Why don't I just take care of it myself? That should help, right? After all, that's what I always did in my past life. Though I always regretted it afterward when post-nut clarity hit, but…'

'Nah… I don't want to go down that path again. There's nothing but guilt waiting for me there… and it's not real satisfaction anyway.'

Having been an avid user of his right hand in his previous life, he had no intention of developing one disproportionately stronger arm in this one.

'It would only lead to guilt and regret later… not to mention, there wouldn't be any real sense of satisfaction. I'd end up as an Incubus who doesn't seek pleasure with a partner but instead relies on his own hand to deal with the problem…'

'What kind of Incubus Devil would that even make me?'

'Yeah, if I go down that path, I'd be turning myself into a joke… No, I really don't want that… anything but that…'

'Besides, my current sword isn't even big enough to be wielded properly with my hands…or maybe not, since my hands are also quite small considering my age… but the short size is also undeniable…' Which wasn't surprising, considering his current body is that of a child. Even if it can get an erection, it's still the cock of a child… how big can it be?

'So, in the end… sigh… I just wish someone would help me out with this…'

'Someone willing to volunteer and accept the small size without making a fuss about it…'

'Perhaps I could turn to Élise for help, couldn't I? If it's her, she would definitely oblige, wouldn't she?'

After all, Élise had been serving him since the time he was an infant and had never once refused a request. Even before he had come to this castle, he would often suckle on her breasts whenever he pleased, and she had always indulged him without hesitation.

'Yeah… Élise wouldn't mind helping me with this…'

'Heck, if it were her, I wouldn't even need to say a word. She'd understand everything on her own and step forward to help me without hesitation.'

'I should probably talk to her about it…'

'I could have her visit me in secret at night and ensure she returns to Father's castle before morning…'

As he was lost in thought, Maria's telepathic voice suddenly echoed in his head.

"Lord Seirios… what's wrong with you?"

Hearing her voice, Seir's hand, which had been cutting through the meat on his plate, froze. He raised his head and glanced at Maria, but the petite girl remained focused on her meal, not sparing him a single glance.

But her voice resounded in his mind once more.

"You seem awfully stressed… Did something happen?"

"I am horny and I am finding it very difficult to control."answered Seir briefly using Telepathy.

"Oh, I see."Maria spoke lightly, not surprised by his answer.

"Don't 'Oh' me… who do you think is responsible for this?" Seir said in a dissatisfied tone.

"But all I did was make you dream on the first morning… I haven't done anything since, yet you're still like this. And I already apologized for it…" Maria replied, in a calm voice. "Besides, it's not like I'm avoiding responsibility for what I did. If you want, I can help you out with this body of mine after breakfast to relieve you of all your stress…" she offered, her tone laced with sincerity…

Hearing her words, Seir was tempted. 'I need someone to help me out here… and she's offering herself. I wouldn't even have to go through the trouble of seducing anyone… Although she's not Roygun… but…'

As he considered her offer, an image formed in his mind—Maria in that revealing leather outfit she had worn when she first visited him.

He hadn't forgotten how the tight material outlined her small breasts, the way her perked-up nipples subtly pressed against the fabric, or how that barely-there black leather panty showcased the delicate shape of her most intimate area. The memory alone was enough to make his body react.

But the lack of curves, the small waist, thin thighs, and that barely-there butt with no thickness to it snapped him back to his senses.

After a brief moment of silence, he let out a sigh and refused her offer."Forget it."

Being turned down once again, Maria felt a tinge of disappointment, but at the same time, she couldn't help but complain."Why are you so against the idea of me helping you? Do you even realize how many people in this world fetishize having their way with a woman who has a youthful body like mine? In the human realm, plenty of old men even break their own laws just to get their dicks inside the cunts of someone like me... They're willing to go to such lengths and risk imprisonment for just a chance... And yet, here you are, turning me down again and again—especially when you yourself are just a little boy."

Seir shrugged. "It's a matter of taste and preference." Then, he added, "Besides, there are also plenty of men out there who prefer boys or older men… some—men and women—even engage with animals… doesn't mean I have to be like them, right? As I said before, I'm not interested in a loli—even if you're legal. If you weren't one, I wouldn't have turned you down… but the way you are right now? You just don't excite me."

Hearing him outright say she had no sex appeal to him, Maria was clearly offended. It wounded her pride as a Succubus, and she snorted in annoyance. "Fine, then! Deal with your horniness on your own—see if I care! Hmph!" And with that, she cut off the telepathic communication, put down the knife and fork on the table, then got up and began to leave, "I am full…"

Surprised by Maria's sudden actions, Zest called out to her, "Maria, you've barely eaten anything."

But Maria simply replied, "I'm sorry, but I'm full. I also have a few matters to attend to, including a personal request with an approaching deadline, so I'd like to take my leave."

With that, she bowed and swiftly disappeared from the dining hall, leaving everyone stunned and unsure of the reason behind her abrupt departure.

After a brief silence, Roygun turned to Lucia and asked, "What's wrong with her?"

Lucia, just as puzzled by her younger sister's sudden departure, shook her head. "I'm not sure…" she admitted, then added, "She seemed perfectly cheerful when I called her for breakfast."

Receiving such a response from Lucia, Roygun turned to the others in the dining hall. "Does anyone here have any idea?"

Yuki and Zest silently glanced at the chair where Maria had been sitting just moments ago before shaking their heads.

No one had a clue… well, no one except Seir, who remained silent and chose not to say anything, "…"

Lucia reassured Roygun, "Don't worry, mistress, I'll talk to her and see if something's bothering her." After a brief pause, she added, "I'm her elder sister—I'm sure she'll confide in me."

"Because you're her elder sister, huh?" Roygun murmured, glancing at the person to whom she herself was an elder sister.

She sighed inwardly, thinking to herself, 'My little brother doesn't seem very interested in confiding in me about what's going on with him…'

Naturally, his constant avoidance did not go unnoticed by Roygun.

In the past four and a half years, Seir had never once averted his gaze from her. He would always look at her with a smile, or eagerness, but for the past three days, he had been purposefully looking away whenever their eyes met. And it was starting to bother her, 'Did I do something wrong?'

'Is he angry at me because I brought him here for training and left him all alone?' she wondered.

'Although he is extraordinarily mature and understanding for his age, at the end of the day, Seir is still a child… Maybe he didn't show much reaction on the surface, said it was all fine, and willingly agreed to wait… but perhaps, deep down, he wasn't happy about it…'

'Maybe I should have postponed my work and spent more time with him and start guiding him as I promised…' she thought guiltily.

'Should I cancel today's plans and spend time with him?' Roygun began to consider.
