Chapter 6. First Fellatio
Sera knelt with her knees folded, catching her breath for a moment. Her upturned eyes glistened with clear moisture. Thump, thump. Even with her resolve firm, her trembling hands moved slowly. Clutching his legs tightly, Sera undid his belt buckle. She anticipated the firm presence bulging through his pants, yet handled it with the delicate care of something fragile. Unfastening the belt draped over his pants, she popped the button. Finally, finding the spot soaked with her juices, she unzipped him—and Junyoung's cock sprang upward from where it had tilted sideways.
The tips of her fingers brushed lightly over his underwear, and Junyoung's breath hitched sharply. "Hah—"
Sera's eyes widened as she gauged his reaction, hesitating briefly before pressing her tongue flat against the fabric. She lapped at the spot darkened by his precum. ...Salty, kinda. Compared to the rich night-bloom scent she'd learned about from afar, "fishy" was too simplistic. Sucking a bit harder revealed a subtle thickness... and viscosity. As the wet patch from his precum spread, Sera traced the clear outline of his shaft, leaning her body closer. The hardness that had grazed her pussy was now right before her eyes.
Slowly licking upward to the tip, the intensifying musk made her unconsciously take the glans into her mouth, exhaling hot breath and affection. "Hah... Sera..."
It hadn't even properly started yet, but the heat alone nearly broke Junyoung. Hearing her name, she looked up at him. This was no act. She hadn't expected to be drawn in this deeply. She wanted to get even closer. She craved confirmation. Her hands grew bolder, tugging down his underwear. His well-loved cock sprang free, leaving Junyoung at a loss with his hands, gripping the wall harder. Below, Sera stared intently at the manhood she faced for the first time as a sex partner, lips pressed tight.
This... is what's going inside me... She'd known it in theory, from videos. But now was different. This wasn't just some random dick among many—it reacted for her. Awe and excitement surged together. She exhaled slowly. It didn't scare her. If anything, the thrill was strangely exhilarating.
I hope it likes me. Was this woman's instinct? The urge to touch the body of the man who shook her so profoundly. As Sera raised her thigh to take the glans in her mouth, her golden hair swayed, brushing his thigh. Then, "Chup—"
Her lips met the freshly beading glans after stripping off the underwear. Awkward at first, like a tentative kiss, then higher, swallowing the head. The spongy yet firm texture filled her mouth, her tongue flicking the center instantly. Pursing her lips tighter wrapped her tongue around it once more. Inhaling deeply brought the mingled heat and scent of a man. Raw, yet oddly addictive. Sera held just the tip between her lips, circling with her tongue tip.
Her crotch tingled. Hard to pinpoint, but a gentle current started deep in her groin. Unforgettable, she swirled her tongue again. Softly, roundly. Her inner thighs quivered faintly. Why? Mouth aimed up, but her body reacted below first. Her lower belly clenched slowly, then released. It tickles. Perfect word. Ticklish, hot, gradually wetting. Unconsciously, she pressed her thighs tighter. The warmth in her mouth sharpened. Each slow circle made her groin hypersensitive, as if linked by the same nerves. Tremors from above merged with the rising itch below. As his breathing roughened, her pelvis subtly rocked forward against his heel.

Sera wasn't the only one heating up. Junyoung felt her clumsy but devoted first blowjob—the slow, focused motions scraping his nerves raw. "Hah... Ngh..." And those melted eyes, the subtle smile, the clearly visible hip sway from above. She's so hot, fuck, Yoon Sera...! His hand on the wall slipped to her nape. Fingers threading through her hair tightened, thrusting his cock into her mouth sucking just the glans. "Mmph...?"
As her lips slid past the ridge below the head, tension gripped his abs, electric thrill shooting up his spine near the limit. Junyoung's cock had an extra-thick ridge there, bulging like concentrated power. Even shallow, it savored fantastical pleasure in a woman's virgin mouth—warm, slick, every tongue bump stimulating him beyond endurance. His hips twitched subtly, gaining force. "Heuk—"
Force on her nape, cock pushing in, saliva pooling without swallow room—clear fluid dribbled from Sera's lips. "Ngh, guk—!" Unlike jerking off. Hands were predictable—speed, pressure, even end timed. But another's will? Overwhelming. Especially from Yoon Sera. "Ah...!" Breath burst out. Mind screamed hold back, but hips thrust too deep, too hard. No... no... He'd finish too soon. Unmanly— But no choice given. He'd thrown it away, eyes squeezed shut. Just once... just once in life... Surrendering to the urge for that one irreplaceable experience, he shoved his cock to the deepest part of her mouth without closing it.
Pressing her throat drew a retching urgh from below, but the clenching pressure snapped his restraint. "...Ah—"
Limit. Spurt— Junyoung unleashed 29 years of virgin cum straight into her mouth. Not one-and-done; it kept dribbling, pulsing, breath ragged. "Hah... hah—" Vision whited out briefly. Stairwell fluorescents seemed to flicker. Faintly recovering, small coughs rose below. "Cough... cough..."
Releasing his cock, Sera bowed her head, catching breath. Eyes brimmed, tears sparkling on long lashes. Nose tip flushed. Held deep till the end, most swallowed, but semen burned her sinuses like it climbed her passages. Exhaling softly, she lifted her head slowly. Looking near-teary, she steadied her breath, nibbling her lip. Then murmured softly. "...You surprised me."
Cheeks flushed deeper saying it. Sticky semen lingered in mouth and throat. Junyoung froze. "I-I... Sera... I didn't—"
Words failed. Ears beet-red, babbling, she watched then smiled cautiously. Teary-faced. "Did you... feel good...?"
"...Huh?" Dumbstruck echo from Junyoung. Sera averted eyes briefly. Glanced at stair floor, lip nibble again. "...I-I..." She started, stopped. Messy golden hair fell beside her face. "...I liked it." Barely audible whisper. Avoiding his gaze, head turned slightly aside.
Junyoung's face burned hotter. "Kuh..." Shame hit; one hand covered his face. Palm over eyes, head bowed. Uncovered ears blazed end to end. "No, I... that's not... I mean..." Still mess. Deep breath in-out, hand pressed face harder. "Ah, damn..." Utter mortification.
"When you ask if it was good... well...... It was really good."
But body differed. Residual heat kept breath ragged, half-naked tension under shirt unrelenting. His cock, staunchly heaving, answered proudly. Sera's eyes flicked down briefly, then up—awkward silence flowed, fluorescent buzz audible.
"...Then let's do it for real now. Something even better."
More desperate in the moment: Sera, yet unsatisfied. Wiggling juice-soaked feet, she reached down, parting her drenched pussy slightly. "We're over 80% compatibility, after all...!"
