My Innocent Childhood Friend's First Time Masturbating
It had already been two weeks since I'd blown my load straight through Jin Dalae's panties and into her completely unprotected pussy.
I sat there with my legs bouncing, wound tight with nerves, waiting on her report.
Today was the earliest proper day you could use a pregnancy test kit — Imtegi for short.
Which was why I'd gotten up at the crack of dawn, hands shaking, waiting on the result.
"Two lines and my life's over."
I'd been told she'd taken the morning-after pill, but nowhere was it written that the odds dropped all the way to zero. People always say there's no such thing as absolute in this world.
No way. We didn't even have sex — how am I supposed to get married over this…
My dick had slipped a little ways into her pussy, sure, but there hadn't been any actual thrusting, so that didn't count.
Being a virgin was already pathetic enough. If I got her pregnant just from dumping some cum in her pussy, I'd die of pure injustice.
Well, these days I've been calling Seo Narae or Areum over to help me get off, at least.
Even so, ever since the whole Dalae incident, I'd gotten so jumpy that I'd been sticking to handjobs and blowjobs. Keeping my dick as far from anyone's pussy as humanly possible.
At this rate I'll never manage actual sex.
What was I even scared of at this point? I'd already gone and asked all four of them to sleep with me.
That sensation of burying my cock deep in Dalae's pussy and pouring my cum into her.
It had lasted all of five seconds, a fleeting instant — and yet it had satisfied my boy better than any onahole ever could. On top of that, I'd gone in raw without a condom, so I'd gotten to enjoy every single fold of her walls with nothing in the way.
The desire to sink my dick into that soft little hole just one more time was already slowly eating away at me.
I was debating whether to call Areum over for a handjob just to calm the erection down when—
Bzzzt—
"!"
The smartphone I'd left on the desk vibrated.
At this hour of the morning, there was only one place a notification could be coming from. I shot my arm out and checked the message—
"Hoo."
I let out a long breath of relief at those words.
If two lines had shown up, we might have ended up as husband and wife on the spot. And then I wouldn't have been able to face her parents at all.
Having a kid in your early twenties is a heavy load. Guess I really can't pull any more dangerous stunts.
We'd both been careless. Even with her panties in the way, there had been every chance my cum could have gotten in.
The odds were slim, but if my sperm had reached her womb and fertilized an egg, it would have snowballed into something we couldn't take back.
Thank god it was a safe day.
I idly pictured her calling me honey~ with a big pregnant belly sticking out.
Huh. That's… weirdly not bad.
When my dick had been inside her pussy, it had felt so good that the idea of pulling my hips back had been almost impossible.
I must have wanted, deep down, to knock up my curvy childhood friend with my own cum.
Not that I had any confidence I could grind myself into the ground working to cover child support starting at my age.
Just in case, I should start buying condoms and carrying them around. A situation like last time might come up again.
I doubted I'd easily find a condom that fit my monster, but being prepared for the worst still mattered.
I was browsing the computer for extra-large condoms when the sound of rain started pattering against the window.
Tap— tap—
"…Is it raining?"
Outside, the sky was already choked with dark clouds, and every so often lightning flashed.
Rumble— rumble—
"……."
Watching the thunderstorm roll in, I found myself thinking of Seol-ah nuna without meaning to. That day had been a lightning day just like this one.
"It's the weekend, so she's probably still asleep."
She stayed late at the office overtime practically every day. A little sleeping in wouldn't be strange at all.
But my body had already finished getting ready to go out.
Click—
I opened the front door like I owned the place and stepped into Seol-ah nuna's apartment.
Between childhood friends, door codes might as well not exist — you just walk in and everyone acts like that's normal. Narae and I made a habit of breaking and entering on the regular, after all.
"…Yep, still asleep."
The lights were off, but I could sense someone in the bedroom. The faint whir of a fan gave it away.
This place never changes.
Seol-ah nuna's apartment, after so long away, felt terribly lonely. With a life that was nothing but the commute between work and home, she probably never had time left over for hobbies.
"Hhk… nnngh…"
"……?"
It wasn't just the fan. Someone was making soft, sobbing little sounds.
I hurried toward the bedroom to find out what they were.
"Eek?! Y-Yuseon? What are you doing here this early in the morning?"
The second she saw me, she yanked the blanket up over herself and forced her expression into a smile.
But she already knew it was too late — she wouldn't meet my eyes, fumbling over her words—
So the wound still hasn't healed.
Seol-ah nuna had lost both her parents five years ago and had been living alone ever since.
That's right. Five years ago, that day had been a stormy day just like this one, lightning and all.
Her parents had been trying to get through the treacherous roads when a landslide swept them away, and they never came home.
Barely an adult, she'd lost her whole family and been living alone like this ever since.
The one silver lining was that all of us childhood friends' parents had never held back on supporting her.
After that, the rest of us had always made a point of dropping by her room so she wouldn't feel lonely.
Once she got a job at a mid-sized company and started working overtime every day, the visits had thinned out a little — but everyone's concern for her was still very much alive.
"…I don't know. I just wanted to see your face for once. I woke up early, so I came over."
She hadn't even stopped by the convenience store where I worked yesterday, so I'd been worried something was up.
"I-I see~ Then could you step out for a second so I can put some clothes on? I'll whip up some breakfast real quick!"
Still dodging. This from the woman who'd never batted an eye about me seeing her naked before.
"What are you getting shy about all of a sudden? I'll make breakfast — just come on out and—"
As I said it, I pulled back the blanket she'd been hiding under.

"Kyaaah!"
"……."
What the hell. Why wasn't she wearing any panties.
She was the type who always took her bra off to sleep because her huge tits got too stuffy, but even so, she never went as far as taking her panties off too.
On top of that, the sheets felt sticky, soaked with some kind of fluid…
"Love juice?"
I'd already gone at it with the other three childhood friends more times than I could count. I knew the smell of pussy juice by heart.
Which meant Seol-ah nuna had been fingering her own pussy and dripping with arousal right up until I walked in…
Then those sounds just now weren't crying — they were moans?
That was a shock. The nuna who still called my dick a wee-wee had discovered masturbation.
Sure, she was a full-grown adult, so there was nothing weird about her getting herself off — but Seol-ah nuna was basically purity personified, so the disconnect hit hard.
"Where'd you learn how to masturbate?"
"I-I heard it from Areum… She said if I think about Yuseon's wee-wee while I poke down here, it feels really good…"
"……."
That damn Shin Areum had corrupted pure Seol-ah nuna. Next time I called her over, I was going to spank her as punishment.
Sit her naked on my lap and smack that big ass until her usual cute face was a complete mess… Wait, was that actually a problem?
"More importantly — you were fingering yourself thinking about my thing?"
"It is weird, right? It feels amazing, but it also feels like I'm doing something bad…"
"I dunno. I do it every d— wait, no. I do it sometimes too, so I don't think it's that weird."
I'd almost reflexively said I jerked it about five times a day, but I didn't want her thinking I was some sex-crazed monkey, so I cleaned the answer up a little.
"Anyway, if you're going to bother masturbating, it's better to have some material. Doing it on pure imagination alone is pretty lonely."
I flipped on the light so the room brightened up, then immediately dropped my pants and presented my half-hard cock to her.
"Whoa…"
With both of our genitals out in the open, an indescribably lewd atmosphere settled over the room.
And since she had zero sexual knowledge to speak of, the whole vibe must have felt brand new to her.
…Stripping so boldly was fine and all, but this is a little embarrassing.
It felt like I was giving a sex-ed lesson. Seol-ah nuna had always been bad at studying, so she'd probably zoned out through every health class and had basically no foundation.
But as a masturbation specialist, I couldn't just ignore this scene. Time to provide some proper spank-bank material so she could have the best possible session.
