Chapter 4
Chaerin stuck out her small tongue.
Lick.
A hot, soft tongue licked up from the base of my cock to the tip of the glans in one long stroke.
“Oh….”
It was a sensation that made every hair on my body stand on end. I involuntarily flinched at the unfamiliar sensation of a woman's tongue.
Even a single movement of her tongue made me feel as though all the blood in my body was rushing to my groin.
Perhaps encouraged by my reaction, Chaerin flashed me a brief, playful smile. Then she gently wrapped her right hand around the rigid shaft.
My cock was so large that Chaerin's right hand could only wrap around half the shaft.
“Then I’ll give you your sexual release.”
Unable to hide her excitement, Chaerin parted her soft lips and slowly took the glans into her mouth.
Sluurp.
A hot, wet sensation enveloped my glans. It felt as if only the glans had moved into another place—a place I didn't know, but one that felt incredibly good.
Chaerin began sucking my glans clumsily. Perhaps she didn't know how to move her tongue, because all she did was work the glans around in her mouth. Of course, even that was stimulating enough.
The pleasure a woman's mouth provided was warm, soft, and tight.
That small space, woefully inadequate to take in my cock, gave me an incredible amount of pleasure.
I couldn't believe that Chaerin's mouth—the same mouth that had always snapped at me like a tsundere—was sucking my glans right now.
I smiled inwardly as I gently stroked Chaerin's pale-purple hair.
“Mmph….”
Greedily, Chaerin tried to take my cock even deeper. She created an almost complete vacuum inside her mouth, sucking so hard that her cheeks hollowed out.
As a result, my cock slid about halfway into Chaerin's mouth. But it seemed that was as far as she could go.
Her throat, inexperienced with anything like this, was resisting firmly.
“Mmph…!”
Perhaps the glans had struck her uvula, because Chaerin let out a pained moan while suppressing a gag. I stroked her head and pulled my cock out for a moment.
Seeing my cock gleaming with saliva, Chaerin looked embarrassed.
“I-it’s my first time… I haven’t properly learned how to give a blowjob yet. I’ll do better next time… Sorry.”
“It’s okay. It’s your first time.”
Rather, I found her clumsy appearance utterly adorable and incredibly arousing.
My twin younger sister was only just learning the taste of men. The thought that I could train her however I wanted made a possessive desire boil up inside me.
Chaerin adjusted her position again. This time, she began sucking my glans while gently giving me a handjob with her right hand.
She didn't stop there. Perhaps she'd learned a great deal about blowjobs in that short time, because she softly licked beneath my glans with her tongue.
The pleasure assailing me from three places at once made my vision swim.
Every time her hand, slick with her saliva and my precum, moved up and down the shaft, my fist clenched involuntarily.
The more time passed, the better it felt inside Chaerin's mouth.
At first, her tongue had been completely still, but now she had become remarkably skilled. Her technique of teasing the area around my urethra with the tip of her tongue was no joke.
Her slick tongue and cheek flesh clung wetly to my cock.
“Haa… Chaerin….”
“Hng, slurp, slurp.”
Chaerin raised her head and looked up at me at the sound of my voice.
Her lips gleamed with saliva and my precum, her eyes were hazy with pleasure, and her cheeks were flushed from the steam.
The moment I saw that cute yet lewd face, the urge to cum surged up at an incredible speed.
I wanted to completely defile this cute woman and make her mine.
I wanted to strip away the towel covering Chaerin's breasts and pussy right then and there.
“I’m going to cum.”
Chaerin's eyes widened at my words. I gently held her head and pushed my hips slightly forward toward the depths of her small mouth.
Brrrzzzt! Brrrzzzt!
At the same time my thighs tensed automatically, a pleasure so intense it felt hot enough to burn my brain surged from my cock.
The satisfaction of ejaculating into a woman's mouth intensified the pleasure even further.
“Hng!? Mmph! Mmph…!”
When an enormous amount of cum filled her narrow mouth, Chaerin's body shuddered as if she'd been ambushed.
Because I'd pushed my cock all the way to the entrance of her throat, Chaerin briefly choked and opened her mouth slightly.
As soon as her mouth opened, the semen filling it ran down the corners of her lips. She belatedly closed her mouth, but it was already too late.
In the end, not knowing what to do, Chaerin spat the semen remaining in her mouth into her right hand.
She spat it out with a bleh and stared at the semen with an expression that suggested she was considering something.
Could it be that she wanted to swallow the semen?
I wondered, ‘Why semen?’ but soon understood. This wasn't an ordinary Earth, after all, and women's libidos were far greater than men's here.
The sight of Chaerin wanting to eat the semen her older brother had ejaculated was incredibly arousing.
“You want to eat that cum?”
I asked purely out of curiosity, without any particular intention. Chaerin looked startled, realizing I'd caught her completely absorbed in the semen.
“W-what are you talking about! I wouldn’t eat your cum even if you gave it to me. You washed me, so that’s enough, right? I’m leaving first!”
Putting on a tough front for no reason, Chaerin hurriedly washed the semen from her palm with water and left the bathroom.
As Chaerin fled the bathroom, her buttocks swayed seductively.
And then I saw a single strand of clear fluid drop from between Chaerin's thighs.
Alone in the bathroom, I looked at my reflection in the mirror.
Even after Chaerin's service, this enormous cock showed no sign of subsiding and remained rigidly pointed upward.
My sexual stamina was impossible to control. I'd already ejaculated twice today, yet it still felt insufficient.
Only after cooling myself down under running water for quite a while could I finally leave the bathroom.
After changing into the fresh underwear and pajamas Chaerin had folded outside the bathroom, the smell of ramen stung my nose.
Two steaming bowls of ramen were already sitting on the narrow living-room table.
“Oh, ramen?”
Mistaking my words for a complaint, Chaerin grumbled,
“Hey, it’s because I didn’t know you’d be discharged today. I hadn’t bought any groceries, so this was all I had for dinner. I’ll make something tastier tomorrow. Sorry.”
“Do you normally eat a lot of ramen?”
“I ate a lot of ramen while you were in the hospital.”
The instant I heard that, one corner of my heart ached.
Someone was apologizing to me for not being able to make me a delicious meal. I was genuinely touched.
And thinking that Chaerin had been eating ramen alone to get by while this body was in the hospital made my heart ache a little. I guess there wasn't much money in the house.
I met Chaerin's eyes from across the table and spoke sincerely.
“If you made it, I’ll like anything. I’ll eat it gratefully. Thanks.”
“W-why are you suddenly saying something so embarrassing? Just hurry up and eat.”
Chaerin turned her head away and spoke gruffly, but I saw that the tips of her ears had turned slightly red.
While I remained seated, Chaerin bustled around the kitchen and set some kimchi in front of me.
Perhaps she was hungry, because Chaerin heartily slurped up the hot noodles.
Her small lips, stained with bright-red ramen broth, came into view. The concern I'd felt moments earlier vanished without a trace, and lust raised its head again.
It was hard to believe that the small mouth currently eating ramen had just sucked my cock.
The movement of those lips slurping up ramen overlapped with the movement of the lips that had sucked my glans.
The scene in the bathroom moments ago came vividly back to life. I was merely watching her eat ramen, yet my groin grew heavy again.
I couldn't tell whether the problem was that Chaerin was too pretty and sexy or that my libido was too strong.
“By the way, hey.”
As I halfheartedly ate my ramen and stole glances at Chaerin's lips, she spoke first.
“I noticed you kept getting messages earlier. If you don’t remember them, don’t bother replying. Anyway, you’re the only one suffering because of those bitches in heat… Tsk.”
“Ah, those. They surprised me. Was I really that popular before?”
“Popular? What do you mean, popular? It’s just because men are rare. You think they’re doing it because they like you? Don’t get the wrong idea.”
Chaerin snapped as she stirred the noodles with her chopsticks. She looked exactly like a child anxiously guarding her favorite toy from being taken away, and I couldn't help laughing.
Could she be jealous?
After we finished eating, Chaerin handed me a small packet of medicine from the hospital. She said it was for the aftereffects of the traffic accident.
Without giving it much thought, I swallowed several pills with some water. Perhaps it was just my imagination, but my head felt a little clearer.
After confirming that I'd taken the medicine, Chaerin stood up and said,
“You were discharged today, so get some rest.”
Chaerin had given me sexual release, helped me shower, and even made ramen. I felt a little guilty about simply resting, so I answered,
“I’ll do the dishes.”
Crash!
The dish in Chaerin's hand fell and made a terrible racket. She stared at me with an expression of disbelief.
“Did you hit your head harder than I thought?”
Perhaps remembering my amnesia, Chaerin gave me a push from behind, concern and irritation mixed on her face.
“What are you doing washing dishes? Men don’t do that! Women do those sorts of things. Go lie down already!”
Guided by Chaerin's firm hands, I plopped down onto the mattress.
“Stop saying useless things and go to sleep. That’s how you can help.”
Concern was hidden beneath her gruff tone.
The softness of the mattress made a chuckle escape me.
‘So being a man here just means getting waited on.’
It was sweet as honey.
Just then, Chaerin, who was doing the dishes, spoke as if she'd just remembered something.
“Oh, right. We’re starting at the academy on Monday.”
“Academy? What kind of academy?”
“You forgot that too? You must have really hurt your head badly.”
Although Chaerin clicked her tongue, there was excitement in her voice.
“Marriage Academy. Search for Female Academy online.”
