Chapter 8 - Childhood Friend Seo Yerin, Masturbation (1)
It's morning.
As always, cleaning the living room is my job.
-Bang!
"...You're going to break the door."
Seo Yerin's door flew open with a sound loud enough to pierce through the vacuum cleaner's noise.
Seo Yerin stood on the threshold with a slightly dazed face.
Dolphin shorts, as always. Her long legs are snow-white.
She was wearing a thin tank top, and the outline of her heavy mounds—which didn't match her slender frame at all—was clearly protruding through the fabric.
The only difference from yesterday was that today, she had properly put on a bra.
"What are you looking at?"
"......"
Yerin had already returned to her usual grumpy face.
Yerin glared at me like that, then trudged into the living room.
"Hey. There's dust on the sofa here. Clean this too."
"......"
The way she pointed at a corner of the sofa with her finger... she really acts like a queen.
I pulled out a wet wipe and gave it a rough swipe.
Seo Yerin plopped down right where I had just cleaned.
"......"
I let out a dry laugh because her intentions for wearing a bra were so obvious.
She was teased so much in my room late last night. She must be sensitive to even the slightest touch of thin fabric.
Seo Yerin crossed her legs and ripped open the bag of potato chips on the table.
-Crunch.
Every time she dumped chips into her mouth, crumbs flew all over the sofa. The effort I put into vacuuming earlier was wasted in just one minute.
"Hey. Han Junyoung."
"What."
Seo Yerin's lips moved as if she had something to say, but she quickly turned her head away.
"...Never mind. Just go boil some ramen."
"Your face will get puffy if you eat ramen in the morning. Aren't you going to school later?"
"Ramen."
"The delivery from yesterday is still in the fridge. When are you going to eat that?"
"Ramen."
"Are you seriously obsessed with ramen? You're just going to eat cup ramen at school anyway, right?"
"Ramen."
"...Ha."
Damn bitch.
I put water on the stove. It's a bigger waste of energy to argue here.
"It's done. Eat."
"Bring it here."
"......"
In the end, I even brought the ramen to the table in front of the sofa.
Why am I being so nice to her, you ask?
......Honestly, I do think I went a bit too far yesterday.
I went into my room and finished getting ready for school.
I put on my bag, went to the entrance, and as I grabbed the doorknob, there was a loud rustling sound from the sofa.
"Hey, Han Junyoung."
"What now."
Seo Yerin, who was half-lying on the sofa, opened her mouth. Even though she was talking to me, she didn't even look my way and just kept staring at her phone.
"...What time are you coming back today?"
"?"
For a moment, my hand, which was about to open the front door, froze.
One year of living together.
She has never once been curious about my return time. She's always acted like she didn't care whether I pulled an all-nighter at school, crawled in at dawn, or died on the street.
I glanced over and saw Seo Yerin's thumb, holding the phone, frozen in mid-air without scrolling the screen at all.
"Around seven...?"
"...Yeah. Got it."
Only after hearing the answer did Seo Yerin's finger start scrolling down the screen again.
-Click.
I closed the front door with an uneasy feeling.
What the hell is wrong with her? Why is she suddenly asking something she never asked before?
#
-Click.
The sound of the front door closing and the door lock engaging echoed through the living room.
Her gaze was fixed on the phone, but she wasn't looking at it.
There was definitely a feed on the screen, but neither the photos nor the text were registering.
"......"
Her head felt dazed.
Yerin got up from her seat, picked up the ramen pot on the table, and dumped it straight into the sink.
The soggy, bloated noodles slammed into the strainer.
'...Han Junyoung will clean it up.'
That guy deserves it.
Yerin returned to the sofa and lay down again.
Two o'clock yesterday morning.
Her memories were spotty, but the sensations left on her body were vivid.
That time when her inner thighs trembled and her whole body thrashed uncontrollably.
The problem was that Yerin felt a sense of satisfaction somewhere.
"...No. Satisfaction, my ass. It was unpleasant. It's not like I'm a crazy bitch."
But her body's answer was different.
From the moment she opened her eyes this morning, her chest felt strangely sore and stiff.
She had become so sensitive that goosebumps would break out along her spine whenever fabric brushed against her skin.
She remembered the humiliation she suffered from Han Junyoung yesterday.
"Bad bastard... I thought my nipples were going to get ripped off......"
Yerin unconsciously stretched the neckline of her tank top slightly and looked down at her breasts.

White breast flesh, heavy and slightly spilling out of her bra. Faint traces of the toys Han Junyoung had attached early this morning remained on them.
On one side, there was a slightly red mark where the sticky gel patch had been attached, and on the other, a clear cupping-like mark left by the round suction rotor that had forcibly pulled at her.
The nipple at the center, despite being teased so much yesterday, was standing erect without a hint of fatigue, poking through the underwear fabric.
"This is crazy, seriously...."
Without Yerin even realizing it, her right hand crept up onto her chest. She lightly pinched the stiff nipple protruding through her clothes with her index and middle fingers.
"...Ah."
It was just a touch of her fingers, but the tingling sensation from the electric patch last night flashed through her mind, and her lower abdomen gave a sharp tug.
At the same time, a sultry nasal sound escaped her lips.
"Ha-ang♡ Hah?!"
Startled, Yerin pulled her hand away like someone bitten by a snake.
What am I doing right now?
In the living room by myself, making noises while touching my own nipples? Me?
Her face flushed red with shame.
But her heart was pounding like crazy, and her inner thighs, which she had been crossing, were pressed together, raising a damp heat.
"...Let's just take a shower."
If she stayed on the sofa like this, she felt like she would really go crazy. Yerin jumped up and headed to the bathroom as if running away.
She closed the bathroom door and stood in front of the mirror.
After letting out a breath, she took off the thin tank top and bra she was wearing all at once.
The two heavy mounds, released from the pressure, dropped and swayed.
"Ha-eut......! Why, why is this happening......"
As soon as the cold air hit her nipples, a chill ran down her spine, and goosebumps broke out all over. Yerin almost slipped. It was because her toes curled up, making her stand on tiptoes.
"Phew, calm down, let's calm down. Wash up quickly, and calm down......"
Yerin pulled down her shorts and panties at once.
"...Haa."
The crevice of her pussy, smooth without a single hair, was already glistening with transparent, sticky arousal fluid.
Yerin's state, wet from the morning, and without even having washed yet.
Yerin in the mirror was breathing heavily with her eyes half-glazed.
"......Crazy bitch. A real perverted bitch."
Her face burned even more at the words she spat out herself. Yerin hurriedly turned her gaze away and cranked the shower handle.
-Swoosh.
A stream of warm water poured down over her head. The moment the water flowed down her shoulders and touched her chest.
"Heut...!"
As soon as the water droplets hit her sensitive nipples, a tingling pleasure surged up her spine. Yerin was startled and covered her mouth with both hands.
'...What's wrong with me, seriously.'
Yerin tried hard to compose herself and squeezed body wash onto the shower towel.
Let's wash like usual.
But every time her fingertips brushed against her nipples, her breath hitched.
"Haa... Eut,"
She hurriedly washed her chest and lowered her hand down.
Her fingers, coated in slippery soapy water, grazed over her swollen clitoris.
"Ah, ah-eut...!"
For a moment, her mind went blank, and the strength left her legs.
-Stumble.
Yerin barely supported her collapsing body and braced one hand against the cold tile wall.
Her ragged breathing echoed inside the small bathroom. It was just a single touch with her hand, yet her insides tightened, and her waist trembled like a bitch in heat.
'...No. I'm just going to wash.'
It's true. This is just a process to wash off sweat.
But her mouth was saying something else.
"Haa... Eung... I think I'm crazy, seriously... Just from one touch of a finger, heut... I'm already leaking fluid down there..."
Han Junyoung, that bad bastard.
That guy engraved a strange habit into Yerin.
Her other hand, not bracing against the wall, was already digging between her crotch.

The soapy water and the arousal fluid flowing from Yerin's pussy mixed to become an obscene lubricant.
-Squish. Squish.
"Ah, ha-at... I have to wash, I have to wash... Heut, it keeps... Eung! Hot water is flowing in there......"
Her index and middle fingers rummaged through the vaginal opening, moved upward, and gently rubbed the pink bean that had swollen up and peeled out of its hood.
"Ha-ang...! Ah, ah... It feels, heut, good... Tingling, heut, it's tingling... Ah-eut!"
Even while muttering that she was washing, Yerin's waist was already swaying back and forth to the rhythm of her fingers.
"Ah, ah-aat! Since I'm washing, I'm washing... Clean inside, eung... If I wash it out while poking, heut, that's fine...!"
Moans echoed through the bathroom.
"Haa, haa... Heut, my chest, my chest... I have to wash my chest, heut, but, ah-eut! It's tingling all the way there too, I'm going crazy... Ah, ah-ang!"
The more the red marks on her chest fanned the flames of shame, the hotter the inside of her pussy became, biting down hard on her fingers and refusing to let go.
"Ah, ah-ang! More, more...! I'm being washed, I'm being washed...! I'm cum, coming, ha-ang, heut, ha-aang!"
The moment she crossed the threshold of pleasure, Yerin's head snapped back.
Her toes curled, scratching the slippery tile floor, and a gush of hot, transparent fluid mixed with soapy water poured down onto the floor from between her trembling thighs.

"Ha-aaat...!! Eung, heut, heu-eueuk...!"
Her vaginal walls spasmed as if having a seizure, squeezing her inserted fingers tightly.
Yerin spent a long while like that, swept up in the waves of pleasure, twitching her waist and shaking her body.
"Haa... Haa... Heut..."
As time passed, her heated breathing gradually subsided.
Yerin hurriedly pulled out her slick fingers and struggled to straighten her body, which had been leaning against the wall.
Her own face, flushed and panting, was reflected in the misty mirror. Her eyes glazed over with pleasure, and her breasts swollen.
'Crazy bitch... I'm a real crazy bitch...'
Yerin covered her flushed face with both hands and shook her head violently.
"Ah, no, I won't, I won't do it......"
Saying that, Yerin dragged her trembling body out of the bathroom.
#
"Haa, haa, haa......Hey, hey, Han Junyoung......"
Yerin called out for Han Junyoung in the living room, wearing only a bath towel.
"......Han Junyoung."
"......"
"Hey, Han Junyoung! Han Junyoung! You're not here, right? You're not!!!"
Naturally, there was no answer.
"......"
And he shouldn't be. Yerin had something to do from now on.
"Ugh......"
Yerin ran to the entrance, her body wrapped only in a towel.
-Click.
She engaged the latch on the front door. Now Han Junyoung wouldn't be able to come in. She was relieved.
"Haa, haa, haa......"

Yerin stood in front of Han Junyoung's door as if possessed.
#
-Ding.
I'm at school when my phone suddenly rings out of nowhere. This notification sound is familiar.
"What is it all of a sudden?"
I went to a slightly secluded spot and opened my phone.
[ PinkBox ]
[ Cumulative Points : 1960 (+80) ]
"....????"
Suddenly, the app's points were going up on their own.
"No, what the hell is this....?"
