Chapter Title: 5.2-2 Sister's Comfort
-----------------------------------------------------------------
“Naibusu? What are you doing? Hurry up and come in.”
“...Just a moment.”
What the hell is going on here?
Taking a bath with my sister at my age?
It hadn't happened once since I possessed this body at ten years old.
Well, we did go in together a few days ago, but...
At least we were wearing swimsuits then.
But right now...
I glanced at the clothes in the changing room basket.
My sister's teacher uniform and stockings, splattered with mud, along with her underwear.
Right now, Sis was 100% naked.
No doubt about it, since she'd stripped right beside me to get in.
I hadn't seen her undress because I'd turned away.
But if I went in there, I wouldn't be able to avoid seeing everything.
I agonized.
Should I go in, or should I run?
“Naibusu?”
“Wah!?”
Sis poked her head out from the changing room.
Beneath her pale face, her soft breasts jiggled.
Of course, her nipples were fully exposed.
“Jeez. Why are you so embarrassed? We're siblings.”
“No, wait, hold on a sec, Sis?”
Sis grabbed my arm and started dragging me in without a care.
“I'm going in, I'm going! Don't pull, it's dangerous!”
“Eek!”
And sure enough...
As she pulled my arm, Sis slipped and lost her grip.
“Ugh.”
She'd already fallen and hurt herself once on the way here.
If she fell again here, she could get seriously injured.
Naked or not, now wasn't the time to worry about that.
-Whoosh!
I launched myself forward and caught Sis in my arms before she hit the ground.
“Phew. You okay?”
Both Sis and I were naked.
Even without the trash game's forced corrections, it was obvious that just being naked together made this a dangerous position.
The warmth and softness of her female body transmitted through my arms supporting her back and legs.
Asking me, a guy, to ignore that she was a 'woman' just because she was my sister was way too much.
“...Ah, yeah...”
Lying in my arms like a hammock, Sis looked up at me with wide eyes.
My dick was poking her side.
Of course it was fully erect after getting so worked up.
The soft feel of Sis's bare skin was transmitting straight to the most sensitive part of my body.
“...Sorry.”
Plagued by self-loathing, I hung my head and apologized.
Not only had I gotten hard in front of Sis, I was poking her bare skin with it.
If there was a hole to crawl into, I'd take it. Maybe the drain over there instead.
“No, no, it's fine! Thanks for saving me! I didn't get hurt thanks to you, Naibusu! Whew, why is the floor so slippery! Ahaha, hahaha!”
Sis forced a laugh, clearly trying to brush it off.
What should I do!? That's Naibusu's dick poking my side, right!? It's that big!? It's nothing like I imagined! Huge! And gross! It looks so scary!
Ugh.
Sis's mind tore my heart to shreds.
But I couldn't let it show.
I quietly set Sis down on the floor.
“...Sis. Can you stand?”
“Ah, yeah. Sorry.”
Sis wobbled as she got up from my arms.
“I'll head out. You wash first, Sis. I can go after.”
I turned my back and tried to leave the bathroom.
But Sis grabbed my wrist again, stopping me.
“...Naibusu. You won't keep your promise? You haven't granted my wish yet.”
“That rigged bet...”
──Why the hell should I?
I turned to retort, but shut my mouth.
I'd seen Sis's expression first, before her mind.
It was a look so heartbreaking, like she was about to burst into tears.
It overlapped with the expression she'd worn before I possessed this body.
Back when she heard our parents had died in battle and had to send her last remaining sibling to the battlefield.
...When was the last time I'd properly looked into Sis's eyes?
Being able to read others' minds was a huge advantage.
But it didn't let me know everything.
Unconscious feedback appeared faster than conscious thoughts.
Since I could read minds anyway if I was nearby, I'd ignored those natural outward reactions.
I might have relied too much on the Mind Rune and missed something more important.
“...Just this once.”
How could I refuse seeing that look on her face?
“Yeah...!”
I let Sis lead me into the bathroom.
* * *
“Hm-hm-hm~ Hm-hm~ Hm-hm~♪”
Submerged in the tub, Sis hummed happily.
I was sunk up to my neck in the same bath, tracing the tile patterns on the wall with my eyes.
Don't turn your head. Don't look at Sis.
I kept hypnotizing myself with that mantra.
“Naibusu, you don't have to be so embarrassed. We're siblings, after all.”
“No... I know, but.”
“It's fine. I know guys get like that from natural reactions.”
I was a little surprised... but it's just a natural reaction, so no need to get too worked up. It's not like he's actually excited, right?
...No. This is actual excitement.
Normally, I could play it off as a natural reaction, but this was definitely an erection from arousal.
The moment Sis slipped, and the moment I caught her, I'd seen everything.
Her breasts, nipples, and down there too.
That brief instant replayed for me in slow motion dozens of times over, every single strand of her golden pubic hair etched into my retinas.
Hah. Golden fields my ass.
What the hell was I even thinking? Damn it.
“Naibusu, you don't have to hug the corner like that. Relax and sit.”
“...No, I'm fine.”
As Sis said, I was huddled tight in the corner of the tub.
To minimize any contact with her.
Our home tub was way too small for two adults. Stretching out our legs meant our bodies would overlap.
“Don't do that. It's making me uncomfortable.”
“Wait...!”
Sis suddenly splashed through the water and pressed right up against me.
“There. Better? Stretch your legs.”
Sis draped herself over me, bodies overlapping.
...Better how?
My dick was now trapped between her ass and my lower belly.
“Hm?”
Sis must have felt it too.
I could only look up at the ceiling and swallow a sigh.
Natural reaction. It's just a natural reaction.
Was Sis trying to brush everything off as a natural reaction?
Should I call this fortunate or unfortunate?
At least the mood wasn't getting awkward.
As I counted the ceiling tile ridges to distract from the feel of her ass on my dick, Sis spoke up again.
“Naibusu, do you have a girlfriend by any chance?”
“...Out of nowhere.”
What now?
Please give me a break.
“I need to know as your homeroom teacher. How about Nanami? You two seem close.”
“Nanami and I... we're friends, but not like that.”
“Really?”
“Really. No girlfriend or anything.”
“Hmmm.”
Sis snorted skeptically.
“Doesn't mean you can just pounce on someone suddenly, okay? I don't want to see my little brother getting arrested.”
“What do you even think I am, Sis...”
She was worried about me, sure.
But it still deflated me a bit.
After all my efforts, it felt futile.
“...If you really can't hold back...”
“Sis.”
Sis kept crossing lines.
I cut her off seriously.
But she didn't stop.
“If it's me, anytime is fine...”
“...”
I went from astonishment to anger.
“Sis. Do you even know what you're saying?”
“...Naibusu?”
I wrapped my left arm around her chest, holding her tight so she couldn't escape.
“You're really okay with this?”
“N-Naibusu? Ngh...!”
I grabbed her floating breast firmly with my left hand.
My right hand went between her legs.
“Ah!”
The softest flesh on a woman's body touched my fingertips.
No panties in the way.
My hand directly touched Sis's pussy.
“N-Naibusu...?”
Sis panicked and belatedly clamped her thighs.
She grabbed my right wrist with both hands, trying to pull it away.
But a woman's weak strength couldn't budge me.
“How's it feel, Sis? You really okay with this?”
“Ngh...!”
I wiggled my fingers, stroking the slit with my fingertips.
I felt her precious place twitch in response.
My left hand kept kneading her breast roughly.
“I'm holding back here, and you think teasing me is fun?”
“N-Not teasing...”
Sis swallowed as she tried to defend herself.
My dick had shifted, pressing against her entrance.
“S-Stop...!”
Sis jolted in shock.
She thrashed, splashing, trying to escape my arm.
“Hmph.”
“Ah.”
I released my hold on her.
The breast I'd gripped with my left hand was red in the shape of my hand.
Guilt stung my chest.
“I'll head out first.”
I stood from the tub we'd shared.
My dick stood defiantly erect, oblivious.
“N-Naibusu!”
As I stepped out, Sis grabbed my ankle.
“Sorry, don't be mad.”
“It's fine. Mad? I'm not mad.”
Honestly, a little.
But it was more pettiness than anger.
Pettiness toward Sis's frustratingly low guard.
I hoped this would give her some awareness.
That even a little brother could turn beastly anytime.
“Yeah? I'll do better, so...”
But Sis wouldn't let go of my leg.
...Can't you just let go? It's embarrassing. And I'm still hard.
I wanted to exit coolly.
“Do what exactly──”
Do what?
I cut off mid-sentence.
Sis had grabbed my dick instead of my leg.
“...Sis. Let go. Right now. Please?”
I was barely holding back already.
Any more stimulation, and I wouldn't be able to.
But.
Sis didn't let go.
Far from it.
“This is the best I can do for now...”
“Ugh...!”
Sis took my dick into her mouth.
“S-Sis? Sorry, my bad. So...!?”
“Mm. *Slurp, slurp, slurp.*”
And she started sucking.
After that, resistance was impossible.
“Ah... Aah... Sis...”
Incest this, whatever that—those words had crumbled to dust.
I lost myself accepting the pleasure Sis gave.
-Slurp, slurp, pop.
Sis sucked my dick diligently, oh so diligently.
Making lewd sounds, rolling her tongue hard inside her mouth.
Devoted entirely to giving me pleasure.
“Sis... Ah... Ugh!”
-Pop, pop, suck.
Sis's face, distorted from sucking my dick, was so beautiful, so erotic.
I couldn't help stroking her cheek, or arrogantly petting her hair.
Love for Sis overflowed; I couldn't contain it.
“Sis, ahn, ah...!”
-Slurp, slur-slurp, pop.
Pathetic weak moans escaped me, hips twitching.
Even when I grabbed her head and thrust, stabbing her throat, Sis yielded her head, face, mouth without complaint.
Her hands resting on my waist, accepting all my desires.
“Sis, Sis! Sis...!”
Like a madman, I kept calling her name, shaking my hips.
“Gulp, pop, slurp, ack, suck, suck.”
Even choking, Sis didn't stop sucking.
Swept by guilt, taboo, pleasure, conquest... all those wild emotions, I ravaged Sis's mouth.
“Sis! Aah...!”
The insane festival soon ended.
I gathered all my filthy desires and erupted into Sis's mouth.
-Spurt!
It was incomparable pleasure.
To Sis, who accepted all of me, I poured out all of me.
“Ngh, haah, aah...!”
-Spurt, spuuurt.
Holding her head, firing only semen.
Sis closed her eyes, accepting it in her mouth.
I felt her mouth filling with my warm cum.
-Splurt...
Squeezing out the last drop, I pulled out of her mouth.
“Haah, haah, haa... Sis...”
After cumming once, my deranged mind cleared.
...What the hell just happened?
Even if Sis tempted first, doing this to her...
My legs gave out; I sank into the tub.
If this were my room, I'd be rolling on the floor tearing my hair.
“Ugh, pfft.”
Sis spat the pooled semen out of the tub.
“Naibusu, sorry. I can't swallow.”
“S-Sis...”
Sis drooped her eyebrows apologetically.
She'd done nothing wrong—I was the scum—yet why was she apologizing?
Guilt and regret crashed over me late.
That I'd sullied Sis, who'd always tried for me. That I'd hurt her.
“Naibusu, feeling better now?”
“Uh... yeah...?”
Better?
If anything, my chest was filled with filthy guilt... but not entirely.
For some reason, it felt... refreshing? Huh?
Like the stress bottled up below my chest had burst open.
...Had I been accumulating stress without knowing?
Yeah, wandering around, stressing, sure.
Did Sis know and milk it out...?
“Naibusu. I'm always on your side. Don't hold back if something's hard—tell me, okay?”
“Uh... yeah...”
Sis hugged my dazed, blinking self and stroked my head.
-Drip, drip.
For a while, the quiet bathroom echoed only with water droplets from the ceiling.
I sat in the tub, held in Sis's arms for a long time.
As if only Sis and I remained in the world.
