Chapter 23
“Eek...”
Han Yaseong let out a moan verging on a scream, shocked at the sight of her swallowing his semen. Hearing it sent a strange thrill through Choi Yujin. This guy's a total virgin... That meant she could claim the title of his first woman. She kept his glans in her mouth. What now? Should I swallow it all...? She hesitated for a moment, but having already tasted it once, she decided to see it through. It was also a way to bind him to her with debt. This innocent boy would never forget the sight of her eating his cum. To etch that memory into him, Choi Yujin—though it didn't exactly appeal to her—sucked greedily at the urethra, drawing out every last drop while keeping his tip between her lips.
Han Yaseong felt like he was going mad from the overwhelming stimulation.
“Ugh... Sunbae...”
Not only had she sucked him off, but she'd swallowed his load too... Every hair on his body stood on end as shivers raced through him. Is this a dream? It seemed too unreal for reality. Yet the pleasure radiating from it proved this was happening right now.
“Fuu...”
Choi Yujin slurped noisily at his glans one last time before pulling her lips away. The sheer volume of semen had left her belly full—nearly half a paper cup's worth. For a first time, he'd unleashed an astonishing amount. She wiped a smear of cum from her lips with the back of her hand and smiled down at Han Yaseong, who lay there limp, gasping for breath.
“Did you like it?”
“......Yeah.”
What more needed to be said? It was the best. Nothing could top this bliss, this ecstasy. He'd never felt anything so intense in his life. Only now did Han Yaseong understand why people did this with women. This was a new world. Just a blowjob had opened the gates to paradise. No one else could offer this—not anywhere. Even that other world paled in comparison. This was on a whole different level.
“Hee-hee.”
Choi Yujin let out a satisfied laugh at his dazed expression. A fleeting thought crossed her mind: Have I gone too far with a first-year guy? But she'd made up her mind. Just this one day of playing with fire. He'd agreed, which was why she'd gone down on him like that. Sucking him had aroused her too, thanks to the strange scent wafting from his cock—a mix of forest, wood, earth, and something primal, wild. It was a smell she'd never encountered before. Not just any masculine musk, but something potent, instinctually stirring to a woman's core. Drunk on it, she'd gripped her kouhai's dick shamelessly and sucked with abandon. Now, though, it embarrassed her. A senior blowing her junior... and swallowing his load? Self-loathing suddenly washed over her. She'd played with fire, but regret crept in. She didn't want to go further.
“That enough for you? We can stop now, right?”
To avoid crossing another line, Choi Yujin checked his intentions—or rather, signaled that it was over. Han Yaseong felt like he'd been struck by lightning. This is it? Already? He didn't crave more per se, but ending it here felt so empty. Better not to have started at all, almost. His face must have shown it, because his sunbae furrowed her brows cutely. This kid's not satisfied. He wants more. He probably wanted to touch her body, kiss it, maybe even slide deep into her slit... Every ex-boyfriend had been the same. Their lust knew no bounds. They weren't happy until they'd pounded her pussy and creampied her. If she didn't let them, they'd sulk and barely talk. Convinced Han Yaseong was no different, Choi Yujin shook her head. Looked like stopping wasn't an option. It'd be like giving a starving kid one bite of meat and saying no more—he'd burst into tears. She sighed and rose from the bed.
“You want more, don't you?”
“Uh...”
Han Yaseong couldn't answer. He did want more, but he felt guilty toward his sunbae. She'd already swallowed his cum... Snapping to his senses, he realized he shouldn't be greedy. He had to respect her.
“I-It's fine. We don't have to...”
Despite clearly wanting it, he said they didn't have to—and that surprised Choi Yujin. Once again, she marveled at his self-control. He'd regained his reason in seconds. And he was considering her feelings. Watching him awkwardly stuff his still-flushed, twitching cock back into his panties, she smiled. She just couldn't dislike this kid.
“No.”
She brushed aside his hand as he fumbled face-down, then gripped it firmly in her palm.
“Ahh!”
The moment her soft hand closed around it, it throbbed and hardened again. Feeling its vigorous pulsing, Choi Yujin couldn't help but laugh.
“You're really sturdy, huh.”
Truth be told, she'd never seen anything like it. That sparked a desire for something naughtier. Han Yaseong's cock was magnificent—sculpted beauty and raw power. No other man's could compare. A bit earlier, after dragging him to her room by the hand, Choi Yujin had hesitated, unsure what to do. Han Yaseong had sat on the bed, fidgeting awkwardly too. Like lovers entering a love hotel for the first time, an awkward silence stretched on. Finally, spotting the massive tent straining his shorts to the breaking point, she felt a mix of amusement and pity.
Ah, I've gotten him way too worked up...
It had to hurt like hell, yet he endured without complaint. That tugged at her heart. Should I at least jerk him off? Steeling herself, she pushed against his chest as he perched on the bed's edge.
“Lie down.”
“Huh?”
Startled, Han Yaseong scooted backward toward the headboard. She'd just told him to lie down, but he'd fled to the far end. With no choice, Choi Yujin climbed onto the bed after him. He huddled there like prey cornered by a predator. Seeing that only made her bolder. His weakness flipped a switch in her.
Yeah, he's just a kouhai... I'll give him this once and be done.
With that casual resolve, she grabbed his legs and yanked them toward her.
“Gasp...”
His legs stretched out, fully exposing the tented shorts. Mortified, he covered it with both hands, but she swatted them away.
“It's okay. Big sis will take care of you.”
She undid the button and unzipped his shorts. The zipper rasped down with a zzzzip, making Han Yaseong gulp nervously. Choi Yujin's heart pounded too, her hands trembling. But in for a penny, she tugged down his shorts—and his panties—together. With a sensation like a cork popping, his erect cock sprang upright.
“......”
Choi Yujin stared, speechless. Han Yaseong's upward-thrusting dick was incredible. Pale as if deprived of sunlight, its shaft was impressively thick—not too big or small, but perfectly shaped. Like a masterpiece sculpture from an artist's sketch.
“Wow, it's pretty...”
The words slipped out unbidden as she ogled it. Mortified that his sunbae had seen it, Han Yaseong turned his head away. The vibe was weird, like she was the guy and he the girl. Choi Yujin had never seen such a perfect cock. Her mouth watered involuntarily, her pussy clenching. What would it feel like inside me...? It'd fill her completely, drive her insane. What a surprise. She'd never expected this from Han Yaseong. He looked like an average guy, but his dick transcended general—it was emperor-class. It matched her ideal perfectly. But until recently, Han Yaseong's cock had been smaller, less impressive. Life in that other world had toughened and strengthened it. He was reaping the benefits big time. After staring for a while, Choi Yujin reached out and grasped it.
“Ngh...”
Feeling the soft warmth envelop it, Han Yaseong whipped his head back to look. His sunbae's right hand gripped his erection tightly. Just that was enough to make him feel like cumming. The instant she touched it, Choi Yujin sensed its scorching heat. And the hardness—like clutching a stone. It didn't bend even under pressure. Not just the shape, but the rigidity was flawless. Han Yaseong had the ultimate cock. Who'd ever guess? No one would imagine a plain-looking first-year hiding something like this.
