A Necessary Cruelty
After reversing time on the cursed heart, immediately after Dimaria had examined the condition of Sia’s anus.
“Is my brother truly creating new curses constantly?”
At the Grand Duke’s question, delivered with a trembling crimson gaze, the family physician Dimaria slowly nodded.
“Yes. That is why new symptoms have begun appearing recently. Still, you could call it fortunate. It could easily have been a far more dangerous curse.”
“A more dangerous curse…?”
“Curses that inflict tangible pain or physically harm the body. Perhaps… Your Grace may need to make a decision as Grand Duke. Just as the previous Grand Duke once did.”
Lua stared at her older brother’s peacefully sleeping face. A decision as Grand Duke. The father who had turned his own son into a vessel of curses to save the next Grand Duke. To prevent the damage this curse would cause, Lua Tanalif, Grand Duke of Tanalif, would have to—
“Dimaria. Find another way.”
“Your Grace.”
“You may criticize me, insult me, whatever you wish. View me as a lord who still throws childish tantrums, or as a wicked employer making unreasonable demands. I don’t care.”
“I have never thought that way, I do not think that way now, and I never will in the future.”
The physician’s answer came without the slightest hesitation. Lua felt a deep wave of gratitude toward her.
“My brother has already lost his pride as a Grand Elf and his dignity as a man. All of it to me. I owe him a debt I can never repay… and yet—”
“In my professional opinion… maintaining your current relationship appears to be the optimal course for now.”
“Pardon?”
To claim that preserving such a twisted relationship between siblings was the best option—Lua could not help but show her confusion.
“Curses are fundamentally influenced by psychological condition. Lord Sia is in a severely withdrawn state, and that very tendency may be suppressing the emergence of more dangerous curses.”
“I still don’t quite follow.”
“For example, had Lord Sia reflected on his situation and come to resent both the family and the world that reduced him to this, a curse capable of causing far greater harm might have manifested instead.”
“Then… you’re saying my brother’s shrunken mentality is directing all the damage toward himself alone?”
“He likely did not wish to drag Your Grace into it, but… yes, that seems to be the case.”
Dimaria nodded, yet the Grand Duke still struggled to fully accept the explanation.
“Then what if we were to make him happy instead?”
“The important factor is not positivity or negativity, but direction. In that regard, joy is far more dangerous. It spreads toward both self and others.”
“If we continue this relationship, my brother will eventually reach his limit and come to resent me. Wouldn’t that make the situation even more dangerous?”
“No. Lord Sia will never resent another person. No matter what misfortune befalls him, he will always believe it is entirely his own fault.”
“How can you be so certain?”
The physician’s tone was so resolute she had abandoned even conditional phrasing. It made no sense. When ordinary people faced misfortune, were they not prone to blame those around them for allowing it to happen? And that thinking was not entirely wrong.
Dimaria offered a sad smile laced with faint disrespect and pity.
“Because your father shaped him that way.”
“Haa—♥”
“Nngh……♡”
Sia lay on the bed with both hands raised high, bound by red rope. Lua was sprawled over him, face buried against his nape, inhaling deeply. The sensation of part of herself being sucked into her little sister’s body sent shivers racing across his skin.
“Haa—♥”
“Hnn……♡”
Lua deliberately exhaled a hot, heavy breath against Sia’s neck, then moved to his armpit and did the same. Her cock, swollen to the point of bursting, pressed down heavily on his body. Goosebumps rose on Sia’s skin; he bent his legs, and his skirt rode up, exposing the soft backs of his thighs just below his ass.
Noticing immediately, Lua slipped a hand underneath and began stroking the plush, yielding flesh.
“Hah……!♡”
“Just looking at you gets me so fucking wet, brother… but these secret little places are the ones that really drive me crazy……♥”
“Nngh……♡ B-but why do you have to tie me up……?”
Sia asked with genuine curiosity. There was no need for Lua to restrain him. Even if all four of his limbs were bound while she was naked, she could overpower him even if he were holding a weapon. It wouldn’t exactly be elegant, of course.
“Hmm, are you curious?”
“Y-yeah……”
The sliver of reason still left in Lua summoned the conversation she had shared with the physician. To keep his brother alive, he had to remain in this shrunken, broken state. The guilt came flooding in. Rather than turning away from it, Lua let it drown her in madness.
“What other reason could there be? It’s because it turns me on more. Seeing you treated like a mere tool instead of a person.”
“I-I see.”
Sia hoped it was merely an abnormal taste born from the curse. Otherwise, whoever became Lua’s spouse in the future would clearly suffer greatly.
“But, brother.”
“Y-yes?”
The slight chill that entered Lua’s expression made Sia tense instantly.
“That isn’t the reaction I want.”
“Huh?”
“Treating a tool like a tool is boring. The fun part is treating something that isn’t a tool like one.”
“What do you—”
“I want you to resist me. Violently.”
“R-resist?”
“Yes. Struggle desperately, as if you truly hate what I’m doing to you. As if you’re begging me to stop right now. Forcing myself on you while you fight back is the most delicious thing of all♥”
The words poured out beneath a pale smile bathed in moonlight were so terrifying Sia almost refused to believe them. Just in case this truly was Lua’s original preference, he offered a silent apology to whoever would one day become the Grand Duke of Tanalif’s husband.
“U-untie me…… please?”
“Ah……♥ That’s it!”
The moment Sia began playing along with Lua’s scenario, the Grand Duke licked her lips in satisfaction.
“L-let me go. I-I don’t want to do this……!”
“Haa……♥ Listen to you lying through your teeth, you pathetic bitch.”
Riiip!
“Eek!”
Lua tore Sia’s top open, then scattered the shredded fabric like crushed flower petals. His pure-white, perky breasts and the pink nipples standing stiffly at their peaks were completely exposed. She circled her fingertips around his nipples, teasing them mercilessly.
The obscene touch made it impossible for Sia to hold back his moans.
“Haaah……♡?!”
“Feels good, doesn’t it? Of course it does, you bitch.”
“D-don’t touch me……! Hnn♡ I-it doesn’t feel good at all……!”
“Like hell it doesn’t……!”
Lua pinched both of Sia’s nipples and tugged them upward.
“Hoooooooh?!♡”
The sudden spike in stimulation felt like a hammer blow to the brain.
“You filthy slut, getting this worked up from something so small—how can you say it doesn’t feel good?”
“Nnghoooooh……♡”
Overwhelmed by pleasure, Sia had no breath left to answer. Yet a question still formed in his mind. Could a woman’s nipples really become this sensitive? He had lived with two of these arousal switches on his chest—how had he never noticed until now?
While he was lost in thought, Lua opened her mouth wide and lowered her head.
“Hahmp♥ Chup♥”
“Haaah?!♡”
She took an entire breast into her mouth, sucking greedily, tongue rolling and flicking the nipple as if it were candy. The relentless barrage of pleasure made Sia want to claw at his own hair to regain control. Unfortunately, his rope-bound hands could only claw uselessly at empty air, fingers clenched tight.
“Haa……♥ Haa……♥”
Even after finally lifting her head, Lua looked far from composed. Sia’s sweet scent had intoxicated her; her mind was a dizzy, chaotic mess.
“Brother, you taste so good……♥ Hahmp♥ Slurp♥”
“Ahn?!♡”
Next, Lua moved to his armpit. From the hollowed dip to the smooth skin of his upper arm, she sucked and licked with wet, obscene sounds. It didn’t feel as intensely sexual as his nipples, yet Sia could sense his body growing hotter and hotter.
“S-stop… that place is… hahng♡ it’s dirty……!”
This time he was half sincere. Armpits were places where sweat gathered; they were unclean. Of course he had washed before bed, but the psychological aversion remained.
“Haa……♥ Haa……♥ Dirty? Not at all?”
Whether it was dirty or not, Lua felt it was dangerous. The more she inhaled, the more clouded her mind became, the heavier her head felt. Yet this female’s sweet body scent was so addictive she simply could not stop.
“Give me your feet too. You lewd little bitch!”
“Kyaa!”
Lua moved so roughly that Sia let out a startled scream. Ignoring it, she lifted his legs, hugged them to her chest, and buried her nose between his soles. The feeling of his own legs sinking into her soft breasts was pleasant. The sensation from his feet, however, was anything but.
Like a bee ravishing flowers, Lua explored every inch of his soles and the crevices between his toes.
“Haaah……♡ D-don’t…! Th-they smell……!”
“Sss—♥ Haa—♥ Exactly. They do smell. The scent of a bitch in heat……! How can you be this obscene? When I first saw these, I thought they were a second pussy, you know? Ah~ I can’t hold back anymore♥”
Lua pressed her cock—on the verge of exploding—against Sia’s folds.
“Nngh……♡”
The heat was so intense it felt like it would burn him. Sia’s body twitched uncontrollably.
“I’m putting it in now, okay?♥”
“W-wait! N-no, not that!”
“Aww♥ I know, I know. Of course……”
“Hnnngh……♡!”
Using her glans to stroke and tease his sensitive perineum, Lua positioned her massive shaft at the entrance of his anus. After nearly committing a terrible mistake last time, even with most of her reason gone she could still respect this one boundary.
“I meant your back hole, obviously♥”
“N-no—!”
The problem was that the boundary Lua imagined and the one Sia imagined were completely different. Sia was willing to let her use him as a masturbation aid or to stroke her himself. But he had no desire to accept her cock in either his pussy or his ass. If Dimaria had not acted quickly last time, his anus might have been ruined.
“Anywhere is off-limits……! If you want a handjob I’ll give you as many as you want……! Feet, armpits, anything……!”
“What are you talking about? Anal is a form of handjob too.”
“H-huh?”
“Putting it in the pussy is real sex. Using the hand-pussy, foot-pussy, armpit-pussy, mouth-pussy, throat-pussy, or asshole-pussy are all just imitations, right? In the end, they’re all just different ways to jerk off, aren’t they?”
Was that how it worked? Come to think of it, he had already allowed her to use his mouth, so maybe the ass was… No! What was off-limits was off-limits!
Schlup.
“Hiiiaaaagh?!♡”
Sia opened his mouth to argue, but the foreign sensation of invasion through his rear entrance stole his voice away.
