Sexual processing.
The moment I heard those words, my mind snapped wide awake.
I couldn’t believe the phrase had just come out of my twin sister’s mouth.
Chaerin must have read the shock on my face, because her own cheeks flushed a deep red.
“Ah—no!
I-I just thought, since you’re an adult now, maybe I should do it like other families do… I-I don’t really want to or anything!”
Her words said one thing, but her expression said the exact opposite.
Whether she was simply a terrible liar or too excited to hide it, her eyes glittered with anticipation even as her face burned scarlet.
“Did I… used to get sexual processing before?”
Chaerin shook her head at the question, then hesitated a moment before answering.
“Not before the accident… but usually once you become an adult, family takes care of it, so…”
So this was a world where family members giving sexual processing was just common sense.
My head buzzed with the electric shock of it—and at the same time, an unbearable wave of excitement crashed over me.
How did sexual processing even work?
By hand?
Mouth?
Or actual sex?
The fact that Chaerin was family didn’t bother me in the slightest.
This body wasn’t mine anyway.
The guilt I might have felt toward its original owner had already evaporated the second a beautiful woman I’d known for barely an hour offered to relieve me.
I was about to drop my pants right then and there when I froze.
What if jumping at the chance made Chaerin think I was a pervert?
What if I’d misread her completely and she actually didn’t want to do this?
“If you don’t want to give me sexual processing, you don’t have to.”
The words were meant as a safety net, but they only made Chaerin more flustered.
“They say it’s bad for a guy’s health if he doesn’t release his semen.
You’ve been in the hospital so long, you probably need to get it out quick… Honestly it feels kind of weird, but it’s something that has to be done, so…”
Even as she claimed it felt weird, the corners of her mouth kept curling upward.
As if she couldn’t hold back any longer, Chaerin grabbed my arm and pulled me down onto the mattress.
“Take them off.
I’ll do it with my hand.”
She swallowed hard.
The faint bob of her throat betrayed every ounce of her nervousness.
She carefully sank to her knees in front of me.
Even after sitting me on the mattress, her attempts to get my pants off were clumsy.
Yet those trembling eyes stayed locked on one place only—the swollen front of my pants.
I couldn’t wait either.
I immediately undid the buckle.
The sound of the zipper sliding down seemed deafening in the quiet room.
The second the underwear came off, my cock sprang free with a heavy slap.
“…!”
Chaerin’s shoulders jerked.
Her eyes went round with a mix of pure shock and raw curiosity.
It was nothing like an ordinary man’s.
Overwhelming size and heat.
Thick veins bulged along the shaft while the brutally flared head twitched, flaunting its presence.
She stared so hard her mouth fell open.
Just that gaze alone made my cock swell even harder, more menacing.
“I-I’ll do it…?”
Her voice trembled as a small white hand approached with extreme care.
Fingers so delicate they looked ready to snap brushed against my burning cock.
I sucked in a sharp breath without meaning to.
A full-body shiver ran through me.
Warm, soft, moist, unbelievably pliant.
It was a sensation light-years beyond my own rough, clumsy hand—the pure pleasure of a woman’s soft skin.
My spine prickled.
Having a girl actually hold my cock for the first time in my life hit with devastating force.
Chaerin’s small right hand couldn’t even wrap all the way around my massive length.
The visual of that size difference alone made my head spin.
This tiny hand was gripping my cock right now.
She couldn’t meet my eyes at all, completely absorbed in the huge cock filling her palm.
When the pleasure made me twitch, she startled.
“Are you okay?
Did I squeeze too hard?”
“No.
It feels amazing right now.”
She could have gripped tighter and I would have been fine, but I didn’t have the luxury of saying so.
Her first strokes were terribly clumsy.
Too slow, too light, completely lost.
She had no idea how to handle a cock and could only rub it up and down.
Even that awkwardness drove me crazy.
The simple fact that my twin sister was blushing while holding my cock was the ultimate aphrodisiac.
Soon precum began to well up from the tip in thick drops.
The clear, sticky fluid slid down the shaft and suddenly her hand started gliding much more smoothly.
Schlick, schlick, schlick.
Now the proper wet sounds filled the room—my cock getting stroked by my twin sister’s hand, the lewd noise echoing in the small space.
Her white hand shone obscenely, slick with my precum.
The filthy sight her own hand was creating seemed to excite her further; her breathing turned ragged and she twisted her hips slightly.
Fingers that had grown a little more used to the handjob began exploring every inch of my cock.
She swept her thumb up the ridged veins, then rubbed the sensitive underside of the head with the soft heel of her palm.
Every time I twitched in response, her eyes lit up like she’d discovered hidden treasure.
“Does this feel good?
Here?
Or here?”
She even brought her left hand in, now pumping me with both.
I tried to meet her eyes and instead found myself staring straight into that deep cleavage.
Every time she moved her arms, those heavy breasts bounced and my mind went blank.
