The Wrong Bed
When I think about it, I realize I’ve never really worried about much in my life. Worrying only becomes possible when you have choices, and I was never given any. For someone like me—born into the Grand Duke’s bloodline yet possessing no talent whatsoever—such luxuries were out of reach. What benefited my little sister was good for me. What harmed my little sister was bad for me. That was simply how things were. So in moments like this, I found it difficult to decide what was right.
‘Which bed should I lie on…?’
Starting today, I was supposed to stay in the Grand Duke’s room. That was why two beds had been placed here. My bed. Lua’s bed. Lua had told me to lie down and wait, but I couldn’t be sure which bed she meant.
“Is something the matter, my lord?”
“Huh? Ah, it’s nothing.”
I had been standing there in a daze until Angelica’s voice snapped me out of it. For now, I walked toward what I assumed was my bed. Angelica would naturally think I was going to sleep there. She watched me lie down, then gently pulled the blanket over my body.
“Sleep well, Master Sia. I shall see you in the morning.”
“Mm. You rest well too, Angelica. And… thank you.”
“Pardon?”
“I heard you spoke to Lua. About… how I’m being treated.”
“……I only did what was natural.”
Angelica offered a quiet smile, then slipped out of the room. Once I confirmed I was alone, I shot upright again and began agonizing over which bed to choose. The Grand Duke’s duties were not yet finished, so there was still time before Lua returned. Would she want to use her own bed? But after I comforted her, the bed would get dirty. In that case, wasn’t it better to dirty my own? Or should I just ask her when she arrived?
Knock, knock, knock.
— Master Sia.
The family physician has arrived.
May I let her in?
The knight guarding the door asked for my permission. I wasn’t used to being treated with such deference.
“C-come in.”
Dimaria, the Tanalif family physician, entered the room and bowed respectfully.
“Master Sia. I have come to cast a soundproofing spell for you.”
“Ah, yes.”
Dimaria waved her staff, beginning to weave the soundproofing magic throughout the room. It was necessary. If anyone overheard the moans we would make, it would be disastrous. If word spread that the Grand Duke was doing such things with her own brother, the dignity of House Tanalif would plummet.
“It is done.”
“Th-thank you for your hard work.”
“……”
Even after finishing, Dimaria did not leave. She simply stared at me intently.
“Wh-what is it?”
“……I debated for a long time, but I believe I should tell you.”
“Wh-what is it? If you need anything, don’t hesitate to say so.”
“Your constitution appears to be rather unique, Master Sia.”
“My constitution…?”
Dimaria nodded and continued her explanation.
“It seems your body adapts exceptionally well to curses. According to my original predictions, your health should have deteriorated far more severely by now.”
“Th-then that’s a good thing, right?”
“……I cannot say for certain. Your body, having adapted to the curses, appears to be generating new ones.”
“Generating curses? Me? I didn’t—”
“I am not suggesting you did so intentionally. Within your body, countless curses have lost their original forms and merged together. Those melted elements are recombining into new shapes, creating curses that did not exist before.”
“Then… is Lua’s condition… because of the new curse I created?”
“That is my theory. She never exhibited such symptoms in the past.”
My heart sank. I had thought that by taking the curses in her place, I had finally become useful to the family. Yet this worthless body couldn’t even contain those curses on its own. In the end, was I only ever going to be a burden to House Tanalif?
“Haa…… Hm? Brother? What are you doing?”
When Lua returned to the bedroom late at night, she found Sia pacing restlessly instead of lying down.
“Ah, yes…… I was waiting for you, Lua.”
“You could have just lain down and waited.”
The two of them now had to perform a very important task to alleviate the symptoms of the curse. The situation carried the same shy tension as a newlywed couple on their wedding night, and Lua’s cheeks flushed pink.
“Then let’s get on the bed—”
As Lua was about to suggest lying down, her eyes fell on the two beds. She immediately understood why her brother had been pacing. Which bed should they use?
Going to Sia’s bed seemed like the better choice. That bed was soaked with his scent; she would probably climax quickly even without much stimulation. But then a strange thought crossed her mind. Using her own bed might be just as good. She wanted to soak her sheets with the fluids her brother would spill.
Her thoughts grew muddled, but Lua eventually leaned toward the latter option.
“Shall we use my bed, Brother?”
“I-I’d rather not.”
“Pardon?”
“T-today I just… want to sleep. I’m tired.”
Lua blinked, staring at her brother. It was painfully obvious he was lying. After all, he had just told her he had been waiting for her, that everything was ready. Lua knew full well that he would never put himself before her, the Grand Duke.
“Brother.”
“Yes?”
“You seem to have no talent for lying.”
“……Mm.”
“Why are you acting like this? Did something happen?”
When Lua asked gently, Sia fidgeted with his fingers and toes.
“W-well… You know, the first day you lost your mind? I… I was thinking it might be nice if you treated me like that again…”
“……Brother?”
Could “like that” possibly mean the way she had assaulted him, hurled abuse at him, and treated him like an object rather than a person? Lua could hardly believe her ears, but Sia drove the point home as if hammering in a nail.
“So I thought if I resisted, maybe you’d do it like back then again… Ehehe……”
“……Today, thanks to your help earlier, I haven’t lost my mind to that extent.”
“Ah, that’s… disappointing? It feels like it would be more ef-efficient if you did it like before.”
Lua still believed Sia was lying. From her perspective, it was impossible to understand how anyone could enjoy being treated that way. Moreover, she couldn’t imagine actually wanting to do those things to her brother. The sight of him powerless against her superior strength, unable to resist, sobbing as he was forced into unwanted acts, curling up like a wounded bird—
Twitch.
But while Lua’s reason rejected the idea, her male organ proudly raised its head, declaring its desire to torment the female before it. Whether because of the curse or not, what emerged when she lost her mind was likely her true nature.
“Ah, i-it’s hard! S-see? You feel the same way, don’t you, Lua?”
Sia’s face was colored half with anticipation and half with fear. Lua wanted to distort that beautiful flushed face further by adding the color of pain.
“Brother.”
“Yes?”
“Everything I say from now on… I don’t mean any of it.”
“O-okay.”
“If it becomes too much for you to bear, you must give me a signal.”
“Th-then I’ll call you Your Highness the Grand Duke.”
“……Very well. Then—”
GRAB!
“Eep!”
Sia’s long pink hair, long enough to drag on the floor, was seized roughly in the Grand Duke’s grip.
“If I tell you to lie down, you should lie down. Why are you resisting?”
“Haa…… haa…… Lu-Lua……”
Clutching his scalp as if it might tear off, Sia trembled violently. Seeing the genuine terror in his eyes, Lua felt her heart waver. Maybe she should stop this kind of thing—
“……Am I a dog? Should I obey without complaint whenever you command me?”
What was this? This insolent tone? Normally he stuttered so badly he could barely speak properly, yet now he dared to glare at her—the Grand Duke—and speak like this? Lua felt something snap inside her mind.
“You fucking bitch!”
“Kyaa!”
The Grand Duke hurled Sia’s slender body onto her bed. Sia barely managed to steady himself and sit up, only to widen his eyes in shock at the shadow falling over his face. A massive, erect cock, bathed in brilliant light, cast a dark shadow across the frightened female’s features.
“Ah……♡”
“You asked if you’re a dog? Of course you are, you bitch.”
“Ugh…… I-I’m not a dog or anything—”
Thud.
“Nngh……!”
The heavy, lead-like glans rested atop Sia’s soft cheek. It was large enough to cover nearly half his face. Hot enough to far surpass the warmth of his flushed skin. Heavy enough that every breath made his lower belly tremble.
“Do you have any idea how lewd your expression is right now? It’s exactly like a bitch in heat. If you know you’re a bitch, then hurry up and suck it.”
“N-no. How am I supposed to put something like this in my mouth?”
“Haa……”
SLAP!
“Kyaa!”
A bright red handprint bloomed on Sia’s cheek. From Lua’s perspective she hadn’t struck him that hard, but for Sia it was a blow strong enough to knock him sideways.
“Anyway, trash like you who can’t do anything for the family except this kind of thing—”
The words spilled out before Lua could stop them, and her reason suddenly returned. That had crossed a line. She knew better than anyone how much her brother had already sacrificed for their house. Why had such words left her mouth?
“B-Brother. Just now I—”
Lua tried to apologize immediately, but the look on her brother’s face made her fall silent. In the center of those lovely golden eyes floated a pink heart shape. A face so lewd it made her cock throb with rage. A face that seemed to beg her to keep degrading him.
It was such an unreal expression that she might have found it strange. But with her cock now in control, Lua’s mind buried that doubt deep inside.
“Haa…… Brother, now that I look at you……”
An arrogant smile spread across the Grand Duke’s face. Lua grabbed Sia’s arm and yanked it upward.
“Ow……!”
His entire body was dragged along by his arm, sending pain shooting through him, yet the hearts in Sia’s eyes did not disappear. Every time he moaned in agony, Lua’s cock twitched violently.
“So you really were just a pathetic masochistic bitch.”
“Th-that’s not—”
“Not what? What’s not, you bitch!”
“Ugh……!”
Lua tossed Sia carelessly onto the bed and headed for her dresser. What she pulled out was a thick red rope.
“Lu-Lua?! Why is something like that in your room—”
“I thought something like this would suit a pathetic masochistic bitch like you, Brother.”
“Kyaaa! D-don’t!”
The Grand Duke climbed atop her small, helpless brother. Sia struggled and resisted, but it was useless against Lua’s strength. In fact, his resistance only aroused her more, making her cock swell even harder. Lua pulled the rope taut with a snapping sound and licked her lips.
“Let’s have a very good time with this, Brother♥”
