His First Load Fills Her Mouth
The soft, yielding flesh wrapped around his cock. The overwhelming weight of it, the sheer pleasure flooding through him — his body trembled of its own accord.
His cock was so big that the head bulged up past her cleavage, but that did nothing to dull the sensation. If anything, it only made it better.
A shudder ran through him.
And on top of everything — Kim Iseo, that prideful woman, was on her knees beneath him, giving him a titjob. The very woman who had always stood in his mind as the archetype of a strong, untouchable girl was doing this. A rush of exhilaration so intense he could barely put it into words surged up through his chest.
"What the hell? Why are you shaking so much?"
"Ah — it's just… it feels too good."
His reaction seemed to please her. The corner of Kim Iseo's mouth twitched upward. A moment later, eyes locked on his cock, she pressed her breasts together harder with both hands and began rubbing them against him, squeezing tighter.
Just being trapped between those soft mounds had been almost too much to bear. Now that she was actively grinding them against him, a moan slipped out of his mouth on its own.
"Nn… haaah—"
"Hey, keep that cock still. It keeps twitching."
Even wrapped in Kim Iseo's soft flesh, the pleasure crashing over him was so intense that his cock kept jerking and throbbing — and she clearly found it annoying. But still…
"Sorry. This is my first time doing anything like this, so I don't really know what to… do. I think it's just because it feels so good."
"Ugh, of course. You really are a total loser. You've never been with a girl, have you?"
She said it like an insult, but the way her lips twitched told him she liked hearing that it felt good. Something about that smug little expression got under his skin, so he shot back — even as a completely different thought ran through his head.
"You… you haven't either!"
Please please please tell me she hasn't. The handjob was clumsy as hell, and this titjob is just as amateur. She has to be a virgin. Please.
It was a unicorn of a fantasy, sure — but he couldn't help it. That was instinct. Every guy, no matter how much he pretended to be a realist, kept a soft spot in the corner of his heart for the idea of a virgin.
"I—I could have if I wanted to! I just chose not to…! You're the one who couldn't! Look at you, getting cocky just because I'm being nice. You're nothing but a toy…"
Whether it was wounded pride, embarrassment, or both, Kim Iseo's body trembled as she answered — and her reaction was everything he'd hoped for and more.
Slap— slap—
Done talking, she focused harder, rubbing her breasts against his cock with renewed intensity. True to form, Kim Iseo adapted fast with her body — her movements were already far smoother than when she'd started, working his cock with growing skill.
"Nn…!!"
The urge to cum was building, but he wanted to savor this pleasure longer — and more than that, he refused to let Kim Iseo look down on him when it came to stamina. He bit down hard on his lower lip and held on.
Kim Iseo flicked her eyes up at his face for a second, then smirked.
"Hey. Does Noona's chest feel that good? Then don't hold back — go ahead and cum."
"Who the hell are you calling Noona…!"
"Who do you think? Your birthday's December twenty-fourth. Mine's January thirty-first. That's almost a full year. Honestly, doesn't that make me your Noona?"
"And who do you think you are, talking back to me like that?!"
The way she tried to steamroll him should have been annoying — but instead, a wave of warmth washed over him. Kim Iseo remembered his birthday. He'd only mentioned it once in passing back in high school.
I knew it. She's liked me this whole time. Then… all those things she did to me back then — were those just her way of showing interest?
The thought made a laugh slip out of him.
"Heh… nn… heheh…"
"Ugh… stop laughing like that, it's creepy!"
She snapped at him, but the corner of her mouth was still curled up. For all her complaining, she didn't seem to mind his reaction that much.
Slap— slap—
The titjob went on. They say human greed has no limits — and the longer she worked him, the more his desire burned hotter in real time. Those breasts wrapped around his cock right in front of his eyes…
God, I want to touch them myself.
Come to think of it, the original deal he'd made with Kim Iseo was that he got to touch her chest and she got to touch his ass. Somehow, between the handjob and the titjob, he still hadn't so much as brushed a fingertip against those breasts.
I'm going to touch them. I have to.
"Hey…"
Kim Iseo's eyes, fixed on his cock, flicked up to look at him.
"What? About to cum?"
"I… I want to touch them too. Your breasts."
Honestly, this was far more nerve-wracking than just sitting back and letting her service him. He wasn't used to asking for things.
Kim Iseo's hands, which hadn't stopped moving since the titjob began, went still. A sudden silence fell. In that brief stretch of quiet, a flood of anxieties tore through his mind, and his eyes squeezed shut on their own.
Ah, damn it, why did I say that? Did I just kill the golden goose? If I'd just kept quiet, Iseo would've kept going on her own — handjob, titjob, whatever came next…!
That would have been fine too, of course. But if he ever wanted to become more than this with Kim Iseo — if he wanted a real relationship, and everything beyond that — he couldn't just keep getting dragged along forever.
Steeling himself, he cracked his eyes open and looked at her. Kim Iseo's face… was the same flustered, embarrassed expression she'd worn the first time she bared her bare breasts in front of him.
"Is… is that not okay?"
He'd meant to demand it with confidence. This was the best he could manage.
Ah, maybe I should just say I was kidding…
At his words, Kim Iseo's eyelids fluttered. She turned her head slightly to the side and answered.
"Th… then go ahead and touch them."
Hell yes!!
Apparently, Kim Iseo found being touched far more embarrassing than taking the lead and exploring his body herself. His hands came down, and at last he was touching Kim Iseo's breasts.
Soft. Yielding.
Sweeping his palms up from underneath that overwhelming mass of flesh sent a tingling current racing up through his fingertips, scrambling his brain like electricity.
Sitting back and being serviced felt incredible — but touching her himself was a pleasure every bit its equal. And on top of that, the sheer sense of accomplishment from demanding something of Kim Iseo and making her submit to it… it almost felt like his self-esteem was climbing.
"Hnn…!!"
And then — that girlish, restrained moan ringing in his ears. Hearing that sound from her, it felt like he'd turned Kim Iseo — who until now had been pure tomboy except for her looks — into a real woman. The exhilaration swelled even higher.
"Kim Iseo. If it feels good, you don't have to hold back your moans."
"Th… this is… haah!! Go to hell… seriously— hnn…!"
"Nn…!"
Every time he stroked her breasts, her body shuddered — and that tremor transmitted straight through to the cock still trapped between them, sending a jolt of pleasure through him that pulled a moan from his own throat.
"Hnn… nn…!"
"Nn…!"
He kept kneading the breasts wrapped around his cock for a while, until Kim Iseo's hands suddenly clamped down over his and pressed hard.
"Huh…?"
"Nngh…! Hnn… you — why won't you just cum already…! At lunch you finished so fast… nn! Stop holding out and just cum alreadyyy…!"
She clearly wanted him to finish already so she could end this. Looking at her reaction, he'd wanted to keep holding on… but honestly, he was at his limit too. The urge to cum had already climbed past the point of no return. Even so, he squeezed out every last drop of willpower and bluffed.
"Hnn…! D… don't wanna. Feels too good. I'm gonna keep holding it."
"You little—! Are you seriously getting cocky with me again?"
That must have gotten under her skin. Kim Iseo's body trembled for a second — then she suddenly ducked her head and, in one motion, swallowed the glans jutting up from her cleavage into her mouth.
A soft, wet warmth bloomed across the entire head of his cock. The already unbearable urge to cum collided with a whole new wave of massive pleasure — and he couldn't hold it anymore. He came, pumping his load straight into Kim Iseo's mouth.
Throb— throoob—
The moment the cum hit her tongue, her eyes went wide with shock and she tried to pull her head back. Maybe it was the dopamine flooding his brain from cumming in a woman's mouth for the first time in his life — he didn't think about the consequences at all. Both hands shot up, grabbed the back of Kim Iseo's head, and shoved her down onto his cock.
"Ghk… ghk— ghk… kkh…!"
Kim Iseo glared up at him with those wide, panicked eyes, but beyond that she didn't move — just forced herself to swallow the cum filling her mouth, her whole body trembling.
When he finally finished and pulled back a little, Kim Iseo collapsed onto the floor, coughing and gasping, spitting what was left of the cum from her mouth onto the ground.
"Kkh… hnn… hkkh…!"
Ah. I really did it. What the hell do I do now…?
She wiped the cum from the corner of her mouth with the back of her hand and glared up at him with slightly bloodshot eyes — and looking at her like that, the worry hit him all at once, far too late.
"I—"
"Hey. You scared the hell out of me. You can't just do that out of nowhere…! Of course a total virgin nerd would pull something like that…"
He'd been about to clasp his hands together and apologize, but Kim Iseo cut him off — and her reaction was nothing like what he'd expected. She was complaining, sure, but somehow she didn't actually seem upset. The weight that had settled on his chest lightened all at once.
"Uh… uh, sorry…! I think I got a little too worked up."
"Haaah. Looks like you're gonna need a lot of training from me going forward."
She stood up and grabbed the coffee from the carrier bag sitting next to him. And then…
Sluuurp—
She drained the entire plastic cup of coffee in one go, then polished off the financier pastry beside it too.
Ah… Suah gave me those…
"Ahhh — now I feel human again. What? What's with that face?"
"Ah… nothing. I was just thirsty too…"
It was a shame, but after she'd been forced to swallow his cum, he couldn't exactly complain. He mumbled something vague. Kim Iseo straightened her clothes, then looked at him.
"You should've said something. I'll buy you one. Come on, let's go."
"Uh, yeah…"
They headed back to the teachers' office together. Not long after Kim Iseo clocked out for the day, Kang Haerin called for him.
"Jinwoo, could you come here for a moment?"
