A Brief Silence in the Snowy Mountains
A brief silence settled over the shelter. Isis simply blinked a few times before opening her mouth in obvious confusion.
“Huh? M-my breasts?”
“Yes. I think that would let me finish.”
“But… will that really be enough? Mine might not be…”
“No. If it’s yours, Sister, it’ll be more than enough.”
“…Really?”
“Yes. I’m certain of it.”
Every noble house made sexual education mandatory. After all, no matter how hard you tried to prevent it, the inevitable would happen, so the lessons existed to at least avoid the worst possible outcomes. Naturally, Isis possessed proper sexual knowledge and understood exactly what aroused a man.
After I gave her repeated, affirmative answers, she hesitated for a long moment before cautiously using the hand that had been massaging my balls to begin removing her clothes. The thick winter coat fell away, followed by the leather armor, revealing pure white undergarments beneath.
Plop!
When she unfastened the hook at the center of her bra, I finally laid eyes on Isis’s bare breasts. They were large enough to fill one hand completely, standing firm and perky with no hint of sag. The snow-white skin and the soft pink nipples at their centers reminded me of a single flower blooming upon an untouched snowy plain.
My mouth moved on its own.
“…Beautiful.”
“Th-thank you. Is this good enough?”
Isis thanked me for the compliment and carefully wrapped her arms across her chest. The way her breasts squished and changed shape under the pressure only made them look more inviting.
I quickly gestured to her. “Sister. I’m begging you.”
“…Okay.”
My cock was already trembling violently, as if it might explode at any second. Noticing the obvious sign of my arousal, Isis flushed all the way down to her neck and leaned in, taking me into her mouth.
“Slurp! Suck… chuu!”
Wet, sticky sounds filled the shelter as intense pleasure surged through my entire shaft. Every time she moved her head, her teardrop-shaped breasts swayed heavily. Those soft pink nipples left faint red trails in the air, brushing dangerously close to my thighs.
It was unbearable. Even in this blissful state, I couldn’t feel satisfied.
“Sister. Can I touch them?”
“Mmm?”
“Your breasts. I want to touch them.”
When I pleaded with desperate longing, her eyes trembled before she shyly lowered her gaze. It was indirect permission.
I steadied my racing heart and slowly spread my palm, bringing it to her chest.
Thud!
A heavy, satisfying weight filled my hand. At the same time, her nipple pressed firmly against the center of my palm, asserting its presence. When I closed my fingers, I felt a softness that seemed to melt every cell in my fingertips, paired with a powerful, elastic resistance. When I gently spread my fingers again, her breast instantly returned to its perfect original shape.
I could die without a single regret.
Even if it was only a fleeting emotion, in that moment it was completely sincere.
As I enjoyed the sensation of her breasts while receiving her devoted fellatio, the urge to climax skyrocketed, piercing straight through the ceiling. It was reaching its limit.
Should I cum now?
The instant I relaxed the tension in my prostate and pulled my hand away from her breast—
Scratch!
Her now-stiffened nipple grazed across my palm.
“Hngh… slurp! Suck! Hauum…!”
Come to think of it, Isis’s breathing had grown rough sometime during the act. Curious, I studied her closely and suddenly focused on her lower body. Her generous hips, perfectly proportioned to her wide pelvis, were swaying gently from side to side. Her tightly clenched thighs stimulated my imagination even further.
There was no doubt her pussy was absolutely soaked with arousal.
Isis had become excited from the very act of sucking my cock while her breasts were being fondled.
The moment that realization hit me, I could no longer suppress my lust.
“Kuh! I’m cumming!”
I reached out with both hands, gripped Isis’s head firmly, and thrust hard as I erupted.
Spurt! Spurtt! Spuuuurrrtt!
A far greater volume than ever before burst forth with tremendous force, flooding her mouth.
“Mmph!? Mmm! Uuup…”
She panicked as her cheeks swelled instantly, but eventually began swallowing with audible gulps, taking every drop. I grew even more excited and squeezed my balls as if wringing them dry, pouring everything I had into her.
A moment later, my climax finally subsided.
“Haa…”
I let out a long, refreshingly satisfied sigh and carefully released her head.
“Cough! Cough!”
The moment she pulled away, she turned to the side and began coughing. Thick white fluid that had clung deep in her throat came spluttering out. The sheer amount was easily equal to three full loads from an average adult man.
I immediately bowed my head.
“I’m sorry, Sister. I lost control and—”
“I-it’s fine… Cough! Cough! More importantly, how’s your condition… Cough!”
Even while suffering, the fact that she was worrying about the ungrateful bastard who had just forced her to swallow his cum was so very like her.
I pulled a bottle of water from my subspace pouch and handed it over. She drank it down urgently, washing every last trace of semen into her stomach.
“Haa… Luan, how do you feel? Is there any cold energy left?”
Having returned to her usual self, Isis once again checked on my condition first. I draped her winter coat over her shoulders before answering.
“Yes, I’m perfectly fine. It’s completely gone. But are you alright, Sister? After swallowing all of that…”
“…There’s no problem. It was already neutralized, so it won’t harm my body.”
“That’s a relief. I’m truly sorry. I couldn’t hold back.”
At least my final shred of conscience had stopped me from thrusting all the way into her throat. If I had, even someone as doting as Isis might have slapped me across the face.
“Mmm… No, it’s okay. You must have been in pain too, Luan.”
“Not at all. I didn’t do anything. You should rest, Sister. I’ll keep watch outside.”
“You will? Then I’ll rest for a little while.”
She must have been quite exhausted, because Isis accepted my suggestion without protest. She closed her eyes and quickly fell asleep.
Even as I monitored the raging blizzard outside, I glanced back at her.
Isn’t she being a little too trusting?
Falling asleep so defenselessly in front of the man whose cock she had just been sucking. She wasn’t even properly dressed—her deep cleavage peeked out from between the folds of the winter coat. Even though I had enjoyed myself thoroughly moments ago, my fingers were already itching to touch her again.
One hour later.
“Mmm…”
Isis, who had been sleeping soundly, finally stirred and opened her eyes. Rubbing them sleepily, she asked, “Luan, did anything happen while I was out?”
“No. The blizzard seems to be dying down little by little.”
“Good, it looks like it’ll pass quickly. You must be tired too—let’s switch shifts.”
The moment she woke up, Isis sat up. What she failed to notice was that she was still completely naked beneath nothing but the winter coat.
Slip—
The coat slid down, fully exposing her petal-like pink nipples. She let out a startled gasp and quickly pulled it back up.
“Ah! L-Luan, I’m sorry! Let me get dressed first.”
“…Of course.”
With her back turned, Isis gathered her scattered clothes from the floor and put them on piece by piece. It was a shame I couldn’t keep staring at her breasts, but the sight of her straight, elegant back muscles was sexy enough that I didn’t mind too much.
A short while later, fully dressed once more, Isis carefully sat down beside me.
“Luan, how long was I asleep?”
“About an hour. It hasn’t been that long.”
“Really? Then we’ve already missed lunch. Did you eat?”
“No, not yet.”
“You didn’t? Then eat quickly. I’ll keep watch in the meantime.”
When she tried to gently push me aside and I stubbornly refused, she gave me a puzzled look.
“What’s wrong? Do you have something to say?”
“Let’s eat together.”
“Together? No, it’s fine. I’ll guard the entrance. So go ahead, okay?”
She smiled brightly, clearly happy that I had suggested it, yet still waved her hands in refusal. Instead, I grabbed her hand and pulled her closer.
“Come on. What kind of monster would be wandering around in this weather?”
“…Are you really sure it’s okay? I did something terrible to you.”
So that was why she had been trying so hard to avoid it. Now that the moment had passed, she was apparently bothered by the fact that she had sucked my cock. I genuinely couldn’t understand it. We had both consented to it.
Above all, it felt incredible.
I firmly rejected her words.
“Not at all. You saved my life, Sister. No matter what a worthless scoundrel I may be, I would never hold any ill will toward my savior.”
“…Then you won’t start avoiding me from now on?”
“Of course not. That will never happen. So, shall we eat together?”
When I asked again as if this were the final chance, Isis finally nodded with a bright expression.
“Alright. If you’re really okay with it, then I’d like that too.”
“Wise choice.”
Having overcome her stubbornness, I pulled preserved rations from my subspace pouch and laid them out. They weren’t luxurious, but considering the extreme environment, it was an excellent meal.
I had just taken a bite of jerky when she spoke.
“Luan, do you remember? That time we got caught in an avalanche and were trapped in these mountains.”
“…Yes. It’s an unforgettable memory.”
“Hehe! What you said back then keeps coming back to me. That you’d become the strongest in the world and protect me. I… was truly happy that day.”
Her face glowed with warm affection as she reminisced.
“And today you really did protect me, didn’t you? Thank you.”
“…It was unnecessary. You would have been fine even without me, Sister.”
Obviously, manipulating mana inside one’s body was far easier than emitting it outward. If the cold energy had invaded Isis herself, she could have purged it easily on her own.
When I put it that way, she shook her head.
“No! That’s not true. Even if it were, I was happy, so it’s fine. I’m really glad you saved me. That’s enough. It wasn’t unnecessary at all.”
“……”
“So don’t say things like that. Understand?”
She took my hand. Faced with that warm touch, I found myself unable to speak. I simply withdrew my hand quietly and took a sip of water.
After continuing our meal in silence for a while, I subtly changed the subject.
“Why do you treat me so well, Sister?”
“Hm?”
“Last time in the student council room you made a huge fuss too. Asking what was so likable about a guy like me that you’d go this far.”
If I had a little sister like this, I would have ignored her completely. If ignoring her wasn’t possible, I would have beaten her half to death so she could never act up again. At the very least, I certainly wouldn’t have sucked cock or offered my breasts to save her life.
Isis answered simply.
“Because I’m your sister.”
“…Is that all?”
“Mother made me promise before she passed away. That I wouldn’t let you be lonely. So until you get married, I’ll stay by your side.”
Her smiling face was radiant. I struggled to suppress the turbulent emotions swirling inside me and muttered cynically.
“Marriage, huh… Is that even possible? Who would ever like a scoundrel like me? Even my fiancée ran away.”
“Th-then we can just live together forever!”
“Are you serious? There are countless men who adore you, Sister. If we lined up everyone who wants to marry you, they’d circle the training grounds a hundred times. Besides, once I become the family head, I’ll need to produce an heir.”
Isis had been chuckling at my playful exaggeration, but her expression hardened at the latter part.
“Luan, I have no intention of becoming the family head.”
“Even if you don’t want to, the people around you won’t let you refuse.”
“Still, that position isn’t mine.”
“Then is it mine?”
If you asked a hundred people who should inherit the Priuli family head position, ninety-nine would name Isis. She knew that better than anyone. That was why she remained silent, unable to answer my question.
“Sister. I have zero interest in the position of family head. I have no desire to spend my entire life trapped in this barren land. So you should take the role. Understand?”
“…Are you truly serious?”
“Yes. So think about it carefully—which choice is the right one.”
“……”
After those words, conversation ceased.
Several hours later, in the late afternoon, the blizzard finally lifted.
Just before leaving the shelter, Isis spoke.
“Luan. What happened here is a secret. Understood?”
“Yes, of course. It won’t leak out to anyone.”
No matter how different her position was from the other young noblewomen, it wouldn’t be good for rumors involving a man to spread—especially if that man was her own brother. There was no need to explain further.
Carrying a single shared secret between us, Isis and I left the shelter behind.
