Know Thy Cock
Let's take stock of how things stood.
Sex had become an ordeal, so I'd summoned my four childhood friends to my place in a last-ditch act of desperation. Two of them had taken the proposition rather well. Seo Narae, though, clearly hadn't been thrilled about it, and so she'd countered with an alternative: she'd finish me off by hand, and I was to content myself with that—
"I'll jerk you off, so make do with that for a while. Got it?"
"So every time I call you over from now on, you're gonna jack me off?"
"Haa… Fine. Whatever. If I leave you alone, you'll just go and sleep with Areum on your own."
Narae sighed and sank to her knees in front of me. The whole thing had the air of a reluctant sacrifice for the sake of her precious little sister.
She probably knows there's no point in trying to stop me hard.
We hadn't spent twenty years as childhood friends for nothing. She understood my habit well enough: once curiosity took hold, I wouldn't rest until I'd thrown myself at whatever it was.
Still—she'd offered to do it by hand. Handjob, HJ, tekoki, shoukou… whatever you called it across languages, it was the kind of act that ranked among a man's purest fantasies.
I'd drifted further from the original goal of actual sex, but this wasn't a bad consolation prize. I hadn't planned to lean on Areum's goodwill to force the issue anyway. And more than anything, looking down on my usually high-handed childhood friend from above felt surprisingly pleasant.
"Then drop your pants already. Let's get this over with so I can go home."
"Wait—right now? I haven't even prepared myself mentally—"
"Enough already, just take them— hogeek!"
The moment she yanked my pants down, my cock sprang free and smacked her square in the forehead, drawing a truly bizarre scream.
"Y-you okay?"
"Do I look okay…? Ow, my head…"
It was entirely her own doing, but I still felt a twinge of guilt. They say you shouldn't even strike a woman with a flower—probably shouldn't hit her with a dick either.
Anyway. Setting the nonsense aside.

"This is seriously… *gulp.*"
Rubbing her forehead, Narae stared at my cock with such intensity that I found myself looking away without meaning to. She was a girl too, after all—having her look at it so openly was a little embarrassing. And the fact that she was seeing it fully hard only pushed my arousal higher.
"Was it always this big? When I saw it at the bathhouse when we were kids, it was a lot more…"
"How far back are you going? We haven't bathed together in almost fifteen years."
Bringing up elementary-school sizes put me in a weird spot. It had been perfectly average even back then.
"Even so, this is practically the size of my forearm! Are you sure you don't have some kind of condition?"
"Quit overreacting… is this your first time seeing a dick?"
I was well-endowed, sure, but exaggerating that much almost hurt my feelings. Surely she'd seen a few in her life.
Contrary to my expectations, though, Narae flushed across her cheeks and answered:
"I-it is my first, so what?"
"Huh."
That was a bombshell. The Narae I'd seen around campus—back when I was still enrolled—had always been the popular type, guys constantly trailing after her. She was already a junior; I'd casually assumed she had plenty of experience. Apparently not.
Then what kind of confidence made her offer a handjob?
She might have thin theoretical knowledge, but zero practical experience. Was that something to be happy about?
After a moment of staring at my cock in thought, Narae set her face with resolve and reached out, wrapping her hand around the shaft.
Thwap—
"Ohh…"
I'd talked a big game, but being touched by a girl was a first for me too, and the dissonance was intense. Ordinarily it was only ever my own right hand.
The faintly cool sensation of her palm closed around the shaft, and an indescribable feeling—
"Okay. If I just move my hand like this…"
"Urgh?!"
Without the slightest warning, she started pumping her right hand up and down with zero restraint.
It hurt. It fucking hurt.
A searing pain tore through my groin as if my cock were about to be ripped clean off. This wasn't a handjob—it was just someone yanking a dick up and down. I couldn't take it. Forcing out a strangled sound, I shoved her hand away.
"Gah…! That hurts! It hurts, damn it!"
"Ah—sorry. Did I grip too hard?"
Finally free, I rubbed at my cock, trying to disperse the pain. So her claim of never having seen one before hadn't been a lie. Speed, technique, pressure control—all of it had been hopeless.
The head's gone bright red. Please tell me it's not bleeding.
Was it even safe to leave the handjob to her? Thanks to the ordeal, my previously rock-hard cock had lost all vitality and hung limp.
"I nearly got castrated trying to get a handjob. Go easy, would you?"
"I wasn't even that rough. Quit whining. Just get hard again."
Easy for her to say—my dick had gone completely silent. I could force it up if I had to, but…
"…Show me your chest."
"What?"
"While we're at it, I want to look at your tits while you do it. It's not exactly a huge ask."
She looked at me like she couldn't understand a word and made her refusal clear.
"Why would I go that far? I told you to be satisfied with my hand."
"It hurt so much I can barely get hard, and you want me to be satisfied with a handjob that painful?"
"Urgh…"
I'd called the four of them over because I wanted to have sex. Narae's intervention was the only reason we'd stopped at a handjob. In that case, she could hardly complain about showing a little chest. We already knew plenty of each other's embarrassing sides as it was.
"…Just this once, okay?"
In the end, Narae fumbled at her front, unbuttoned her white shirt, and in the same motion stripped off her bra as well.
Bounce—
"Whoa. Holy shit."
"What kind of reaction is that?"
Seeing live breasts with my own eyes—the kind I'd only ever watched in porn—pulled a curse out of me on instinct. The volume was perfect, of course, but so were the moderately wide pink areolae, exactly my type, and the neat, unblemished nipples.
I really want to grab them.
Ten years ago those chests had been flat as boards; the fact that they'd grown this splendidly left me stunned. Judging by the size—
My dead cock made a full recovery… no, it grew even harder than before.
Narae watched that vivid revival with a complicated expression.
"Men really do lose their minds over breasts."
"I don't know. If I had to pick, I actually prefer asses."
"Who cares…"
Looking thoroughly uninterested, Narae gently took my cock in her right hand again and began to stroke. This time, unlike before, it was a considerate handjob that actually took her partner's feelings into account.
"Ohh."
"That's creepy. Stop gasping at every little thing."
"It actually feels good—what am I supposed to do? Ah, a little harder."
"Tsk. You're full of requests."
Her words were rough, but she carefully obliged every one of them. With a personality as responsible as hers, she couldn't just abandon a job once she'd taken it on.
For the first time, I'm glad I have childhood friends.
If a hand alone felt this good, how incredible would actual sex be? It was a shame, but for now I'd have to settle here. That was the condition under which she'd agreed to the handjob.
"……."
In silence, she kept working her hand along my shaft. At first I'd thought I could hold out, but the first-ever touch of a girl's hand steadily ate away at that composure. I didn't want to be thought of as some premature guy who finished in a few minutes, so I tried to endure—
"Ah, it just twitched. Looking at it this long, it's kind of cute."
"?!"
Between Narae's full breasts and that virgin-like unfamiliarity with a cock, my excitement was stoked past the breaking point. I couldn't hold the pressure and came hard.
Pshhhk—
"Ah…"
Semen shot out in several thick spurts, nearly high enough to hit the ceiling. Narae dodged it with surprising skill and immediately launched into complaints.
"Ugh, you came so filthy much… Tell me none of it got on my clothes."
Apparently finding the mess on her hands unpleasant, she snatched up a nearby tissue box and hurriedly wiped herself clean. For some reason, even the sight of her scrubbing my semen off with open disgust was turning me on…
"Whew. Finally got it all. How much did you even shoot?"
"Don't ask me—I don't measure the volume."
"Still, this should be enough for you. Don't do anything weird, and behave yourself for a while."
Honestly, it wasn't enough. Even on ordinary days I usually went for at least a second round. One look at my cock, already standing stiff again, would have made that clear.
But Narae either hadn't noticed or didn't care; she simply put her clothes back in order and prepared to leave.
"What kind of assignment has you in such a rush? Are you that busy?"
"I've got time. It's a group project—I just don't trust the rest of them."
A group project. A worry I could no longer share, having dropped out of university long ago. There was no point piling more onto her plate, so the decent thing was to let her go quietly.
"I'm heading out, then. Clean up after yourself."
"Y-yeah."
Watching Narae's retreating back, I reminded myself once more.
I still wanted to have sex.
