How far gone was this world?
Or rather — how far toward perfection?
I barely reined in the excitement boiling up inside me and asked in the most casual voice I could manage.
“Do family members usually attend a man’s shower too?”
Silence held outside the door for a beat.
One second.
Two.
Chaerin let a tiny pause pass before she answered.
“…Yeah.
Of course.
Men are precious, so women taking care of them in every little way is just common sense.”
Common sense.
The word slammed through my skull.
What a glorious, perfect common sense.
The women of this world might as well have existed for men.
An amusing guess brushed through my mind.
A gender-reversed world.
Women with overwhelming libido and scarce men.
And a twin older brother who had lost his memory.
Was Chaerin using this situation to feed her own desire?
But what did that matter?
To the me of right now, it made no difference at all.
Rising lust was numbing my reason.
I took the doorknob in a wet hand and pulled it open.
The moment the door swung wide, Chaerin stood there — barely covering her breasts and pussy with a single white towel.
The narrow bathroom, which had no bathtub, filled completely the instant both of us stepped inside.
Steam fogged the mirror; the scents of shampoo and soap hung in the air — and over all of it, Chaerin’s sweet woman-smell packed the space dense and thick.
Her bare white shoulders and slender collarbones, the smooth lines of her legs left uncovered by the towel, drove straight into my vision without mercy.
The full outline of her breasts hanging precariously from the edge of the towel, and the secret place one could only imagine below — all of it made me hard.
Chaerin flushed under my blatant stare but did not look away.
Instead she met my eyes boldly and snatched the shower puff from my hand.
“Don’t just stand there staring.
Turn around.
I’ll wash you.”
I caught the excitement hidden under her snippy tone easily enough.
I gave a short laugh and turned my back without protest.
Soft foam and a small, warm hand began to stroke across my broad back.
Slick, slick.
The shower puff in Chaerin’s little hand scrubbed over my wide back.
Body-wash foam rose thick and covered me in a slick, slippery feel.
Neither of us said a word.
I didn’t know what there was to say.
The fact that my twin little sister stood right behind me, naked under nothing but a towel, was so fucking hot I could barely stand it.
Even at a glance her breasts looked like D-cups.
No — E-cups?
I had never properly seen a woman’s chest before, so I couldn’t tell.
Maybe even F.
“Front too.”
Judging the back finished, Chaerin spoke shortly.
I turned slowly to face her.
“Ah, you…?”
Chaerin swallowed a breath at the unexpected sight.
In that cramped space, right in front of her, my cock stood fully erect, head lifted as if it might burst.
Thud.
Wet with water and radiating a savage presence, my cock stabbed straight into the towel covering Chaerin’s stomach.
I almost felt the skin of her belly through the fabric.
“I-It got hard again…?”
Chaerin fidgeted her fingers, her expression flushed with excitement.
She looked back and forth between the cock prodding her stomach and my face, and lightly rubbed her thighs together.
I looked down at her and said quietly,
“For my cock — not the shower puff.
Use your hand.”
It was for me, yes — but also for Chaerin, who clearly wanted to touch it.
“Wash it carefully.”
Chaerin bit her lip as if hesitating for a moment, then seemed to make up her mind and dropped the shower puff from her hand.
With one hand she clung precariously to the slipping towel; with the other she reached for my cock.
Her small, soft hand wrapped around me.
She worked foam over my cock and began to wash it with little kneading motions.
Holding the towel with one hand left her posture awkward — and that only made it hotter.
Knead, knead.
Slip, slip.
Her small hand rode up and down the shaft and carefully caressed the head.
Having given me a handjob earlier, her movements grew more practiced by the second.
The brief handjob ended.
Chaerin slid her hand lower and gently washed my two heavy balls as well.
After working my cock for a long while, she rinsed away every last bit of foam, unable to hide the regret on her face.
“I’ll wash your feet too.”
As if reluctant to take her hand off my cock, she slowly crouched and knelt at my feet.
Then she began carefully washing between my toes.
That obedient posture was deeply satisfying.
After washing my feet for some time, Chaerin absently lifted her head.
“Ah…!”
Her gaze locked dead on my cock.
She stared at it with eyes that held something close to awe.
Looking down at her, I reminded her of what she had said earlier.
“You said you’d do it with your mouth.
Can you now?”
Chaerin did not answer in words.
Instead she nodded, bright with pleasure.
And slowly, she opened her mouth.
Between her moist lips, neat white teeth and a red tongue came into view.
