17. Thrusting and Grinding (2)

[Thrust! Thrust! Squelch! Squelch! ❤️] Even after the quest completion notification and the reward successfully arriving, I kept flexing my cock, relentlessly grinding it against Kim Yunah's slick pussy lips.

I was addicted to the slippery yet soft embrace of her tender labia wrapping around my glans, thrusting my cock purely for pleasure, quest be damned. Under the gaze of all those students, Kim Yunah noona couldn't move a muscle as her precious spot was invaded, reduced to ragged breaths and a flushing face. That sight fueled my baseless confidence even more, my cock—dripping precum—stabbing at her soaked, puffy mound. The studio lights made my ‍‍‌‌⁠​​⁠‌​​‍​​‍​‌​⁠‍‌‍⁠⁠‌⁠‌‍‌‍‌‌‌‍⁠​‌​‌​‌‍‌‌‌⁠‍​​‌‍⁠‌‌⁠⁠glistening glans, slick with Cowper's fluid and buried between her thick pussy lips, look utterly obscene.

"Hngh..." A faint moan escaped her tightly pursed lips, her sweet body scent hitting me, driving me into a frenzy as I ravaged her folds even harder. Midway through, she shot me a look that screamed, 'Are you really doing this?' but I ignored it, bouncing my cock up and down her long, vertical slit between her crotch.

The reason I could hump so boldly amid all those prying eyes? Surprisingly, it was thanks to Lee Se-kyung, the director. She'd instructed noona to bring her lower body ‍‍‌‌⁠​​⁠‌​​‍​​‍​‌​⁠‍‌‍⁠⁠‌⁠‌‍‌‍‌‌‌‍⁠​‌​‌​‌‍‌‌‌⁠‍​​‌‍⁠‌‌⁠⁠closer to mine, hiding our groins behind her firm thighs—visible only to us, not the others. Free from worry about the ajummas sketching us, I feasted on her plump pussy lips to my heart's content. Meanwhile, noona—caught off guard—stopped trying to rein me in, closing her eyes like she was meditating to suppress her leaking reactions.

I don't know how it felt for her, but those 20 blissful minutes had me teetering on the edge of orgasm, until our naughty frottage finally ended.

[Beep beep beep beep!]

"Huuu..." The alarm signaling the end of the ‍‍‌‌⁠​​⁠‌​​‍​​‍​‌​⁠‍‌‍⁠⁠‌⁠‌‍‌‍‌‌‌‍⁠​‌​‌​‌‍‌‌‌⁠‍​​‌‍⁠‌‌⁠⁠fourth round blared, and noona rose with a deep, pent-up sigh. Just before she covered her crotch with both hands, I caught a ‍‍‌‌⁠​​⁠‌​​‍​​‍​‌​⁠‍‌‍⁠⁠‌⁠‌‍‌‍‌‌‌‍⁠​‌​‌​‌‍‌‌‌⁠‍​​‌‍⁠‌‌⁠⁠glimpse of something leaking from her pink pussy hole amid the pussy lips marinated in my precum. My raging cock twitched hard at the sight; I hurriedly covered it and dashed for my robe to hide the precum-slick monster from the students.

Unlike previous breaks where she'd wait, noona stormed out ahead. Following her to the waiting room, I found her arms crossed, mask off, face pissed.

"Hey! What the hell was that?!"

The door clicked shut behind me, and she laid into me—not yelling, but seething with anger over what just happened. Time to pay for my fun. My only play? Top-tier acting to calm her down. I'd use what she'd asked before the first round.

"Noona, truth is... I'm a virgin. First time seeing a naked woman for real. I just got too excited and..."

Head bowed, puppy-dog eyes, mixing in the virgin lie—she faltered, her flushed, huffing rage pausing. Then, with a different kind of sigh—not the exasperated one from the studio—she softened a bit.

"Aigoo... Hyungsik, you should've said something sooner. Can't just get hard and grind like that on site... Lucky no one else saw, or what if those ajummas had? Seriously..."

Unable to stay mad at my "virgin confession," she vented alone, then pulled wet wipes from her small bag, handing me one after taking another.

"You leaked a ton back there... Wipe up first. If you're gonna get hard again next round, go handle it in the bathroom now. I'll tell the director to delay start a bit."

Luckily, the grinding issue blew over. Worried about my next erection, she even suggested jerking off solo. Already on the brink from rubbing her pussy, it sounded smart—until the quest popped up in the corner of my lens, one I thought was done during the gig.

The quest's tone felt totally different as I read it, nearly yelling at the "cum on her pussy" demand—but I held it in, taking the wipe. Back turned, I cleaned the precum off my glans, rereading the second add-on quest slowly. Same title and rewards, but now demanding ejaculation? I stifled a laugh, wiping clean—right as noona, probably done with her own cleanup, suggested the bathroom again.

"Hyungsik, seriously, go now. Better safe."

Her urging me to drain beforehand for smooth posing in the last two rounds sparked pointless rebellion. I'd planned to skip despite the item ticket—ejaculating seemed impossible anyway—but her persistence woke my inner contrarian. Plus, people say the first time's hardest; after that, it gets easier and bolder. What once seemed too much—"cumming"—now felt... not so bad.

Next pose: legs crossed oppositely, lying back-to-back-ish. I'd face away from the ajummas, so no one would see me cum. My mental scale tipped toward the quest, like before. Since the Yas System, I'd grown impulsive... Anyway, bathroom? Nah. I waved her off.

"I'm good, noona. I'll hold it."

"No need to be shy. Other male models hit the bathroom mid-session if they get excited."

"Nah, it's calming down. Really fine."

Accepting my polite refusal, she checked the nearly over break and stood.

"Let's go. Just two poses left—please don't get all worked up again."

She patted my arm softly one last time before opening the door. I followed to the studio, clenched fist hiding a crumpled wipe for any... aftermath. Couldn't leave cum puddles if I blew. Decision pending on the quest, I ditched the robe, hand shielding my crotch max, assuming a scissoring pose groin-to-groin with noona.

[Squelchhh! ❤️]

Unlike the prior face-to-face, my firm balls pressed her soft pussy lips, my still-soft cock draping her perineum and into her deep ass crack.
