Stand-In (3)
I wiped my damp hand on Seoyeoni's thigh. She was just trembling uncontrollably, oblivious to what Hyeonwoo was doing. When his hand touched her, she flinched and glanced over, but then spread her legs even wider. Her flushed pussy throbbed on its own. Her clit was swollen beyond compare to before. How could it be like this? I'd fingered her way more times than Hyeonwoo ever had... but I'd never seen Seoyeoni this worked up. I hadn't even known hands alone could do this to her.
"Hoo." Hyeonwoo slipped off his bathrobe. His cock wasn't even fully hard yet, but it dangled between his legs several times thicker and longer than mine. I quickly turned my head away, only to catch Seoyeoni's expression. It wasn't a face I'd never seen before. Once, when she was aroused and clinging to me, looking up with those pleading eyes, begging me to do something—that was it. Short of breath, desperate. And now, she was making that exact face while staring at Hyeonwoo's cock.
"Ah..." She must've felt my gaze. She quickly bowed her head, fixing her expression. That hurt even more.
"Seoyeoni, come here." Hyeonwoo lay back on the bed and beckoned her. Head still down, she looked lost, not knowing what to do. I kept watching her flushed face, and she bit her lower lip before awkwardly climbing onto his thigh.
"Hyung, you can jerk off if you want."
"Ah, yeah...! R-right..."
"You're dying over there, huh? Take off your pants too. Looks like you're about to burst."
I fumbled with my crotch, gripping my cock over my pants, and Hyeonwoo chimed in.
"Jeez. You're really making this awkward."
"N-no, it's fine. I'll just take it all off."
I stripped off my pants and underwear completely. There I was, pathetic erect dick out, wearing just a t-shirt like some clown. Shame welled up, but compared to this arousal, it was nothing. Amid the humiliation, my cock twitched, precum dripping down. I hurriedly wiped it away in surprise.
"Ah, come on, don't drip on the floor. Tissues are over there—put some under it."
"Ugh..."
I staggered up unsteadily and placed tissues under my cock. Seoyeoni and Hyeonwoo were on the soft bed. I was kneeling on the hard floor below, prepping to jerk off. The misery made me unable to lift my head. Seoyeoni... what kind of face are you making at me right now...?
"Seoyeoni, you see how hard Minjun hyung is?"
"..."
Her name made my cock twitch again. No answer, but she probably nodded. Precum oozed onto the tissue with a sizzle, my heart pounding like it would explode.
"Minjun hyung's loving this. So what're you gonna do about it, Seoyeoni?"
"Wh-what...?"
"Show him everything, right? For Minjun hyung?"
Hyeonwoo tossed it out with a mocking sneer.
"Hyung, say something too. You're just frozen there doing nothing."
"Hik... N-no, I'm...!"
Startled, Seoyeoni gripped Hyeonwoo's cock tight. Our eyes met. Even as she clutched it, her face was a mess of tangled emotions. She was still anxious, it seemed. Especially after I'd cum right in front of her without even doing anything.
"Seoyeoni..."
"..."
"I-I'm really... really into this right now?"
I barely held back the surge of emotions.
"Don't hesitate—just do it. No need to worry. A-and you... you're probably feeling it too..."
"Let's go~"
Before I could finish, Hyeonwoo pulled her in. She straddled his thick shaft. A wet squelch hit as her face crumbled in an instant.
"Hngh, uht... O-oppa...!"
Seoyeoni moaned, shaking her head wildly, and Hyeonwoo nodded at me to keep going. I swallowed hard.
"We agreed to this... I'm really okay with it..."
"Hnght...! Hehng, heunggh..."
I wasn't sure if she even heard me. Hyeonwoo thrust shallowly from below, and all she gave back were moans. The room filled with her cries and those lewd squelching sounds.
"Haahk, heunnggh... Unght...?"
The cock under her pussy swelled bigger. It tried to rise at a perfect angle, but her weight pinned it down. Her puffy clit ground against the shaft, getting mashed relentlessly. She tried lifting her hips but couldn't quite manage. Instead, she just shook her head faster.
"F-feels good, right? I'm good with it too, so keep going... for me..."
"Kyaa...! Hiiik...?!"
Seoyeoni suddenly dropped her head. It was the same motion as before, but totally different. Fists clenched tight, toes curled, body shuddering violently. Did she... cum...? Again...?) Hyeonwoo patted her ass, and she twitched in waves. No doubt about it—she'd climaxed. And this was only the second time... before we'd even started properly. Not just the frequency, but how fast she came. It seemed like the slightest touch from Hyeonwoo sent her over.
After a long shudder, Seoyeoni went limp. Then she gave a small nod. Head still bowed, but I saw it clear as day.
"Oh ho. Seoyeoni says she'll give it her all."
"What...?"
"For her pervert boyfriend. Right?"
Hyeonwoo smoothed her disheveled hair. She was still twitching atop his cock.
Seoyeoni balled her fists.
"I-I..."
"..."
"This is all for you, oppa... You like it too... right?"
She murmured softly, unclear if it was for me or herself.
"Seoyeoni...?"
"Since oppa likes it... No, even if I... it's okay, right? Right...?"
Seoyeoni glanced at my cock. Before I could respond, she sighed in relief, taking its twitching as agreement. My heart sank. It felt like she'd let go of something deep inside. This was what I'd wanted so badly, but now another feeling bubbled up. I wished she'd keep hesitating. Keep worrying about my reactions, staying anxious... not letting go completely...
"Guess I gotta step it up too."
Hyeonwoo smirked at my trembling form.
"Seoyeoni, say what you told Minjun hyung last time. Didn't he love that?"
"Ah..."
"Might as well go all in. So, what're we doing now?"
Seoyeoni swallowed hard. She hesitated, then glanced at my twitching cock and clenched her fists again. It wasn't even an answer, but she kept interpreting it that way.
"I'm gonna do it with Hyeonwoo oppa now... Gonna have sex with Hyeonwoo oppa...!"
My heart plummeted again. It hit different from the video—way more real. Still a bit performative, but she was right here, voice so vivid. My cock throbbed, precum soaking the tissues to the point I might need new ones.
"O-oppa, don't jerk off..."
"Nah, tell him to today. Look at him—he'd die without it."
"...Th-then jerk off from there."
Hyeonwoo burst out laughing.
"Haha, what? Isn't that too cute?"
"..."
"But tease him more, rile him up like you're playing. Though hyung seems plenty satisfied anyway."
Hyeonwoo tossed me the tissue roll.
"Hyung, don't drip on the floor."
"Ah... S-sorry...!"
I rolled up fresh tissues under my cock. I didn't even know anymore. Maybe I should just let go too.
"Wanna try solo this time, Seoyeoni?"
"S-solo...?"
"Yeah, you can do it."
Hyeonwoo tapped her ass, and she hesitated before squirming. But not for long. One more glance at my twitching cock, and she braced her hands on his abs. Propping herself up, she rocked her hips back and forth, grinding her pussy on him. Like she'd adjusted, she slid down to the base with a squelch, then up to the head. Repeat. Was she rubbing her pussy or stroking his cock? She even lifted her hips herself, slotting it perfectly between her folds. The wet sounds grew louder. Her moans turned lewder. It was like she'd made some resolve. The hesitation faded. Her awkward hip circles smoothed into something natural, slutty—swiveling and shaking with raw lust. I couldn't tell if it was for me or her own pleasure anymore. Like she'd unleashed all the pent-up pressure.
I stared at her blankly. Letting go? Impossible. My girlfriend... my Seoyeoni was shaking her hips on another man's cock. Finding the spots that felt good all on her own.
"Hyung, pass a condom?"
"Uh?"
"Condom. Condom."
It hit me like a hammer. Right—no condom yet. Not penetrating, sure, but grinding and rubbing bare like that... nothing between them. Hyeonwoo's raw cock on Seoyeoni's bare pussy.
"Wh-where... where're the condoms?"
"Hnght...! D-drawer... second one..."
"Ah..."
Seoyeoni answered for him. I opened it—stacked full. I snapped out of my daze. Had to cover him quick.
"What? Not me—give it to Seoyeoni. Condoms are her job."
"What...?"
"Duh, unwrap it first. No sense."
Trembling hands tore the wrapper. A condom way bigger than mine popped out, unsettling.
"Nah, just give it here. Seoyeoni, keep rubbing your clit on it."
"Hng... L-like this...?"
"How else you gonna roll it on? Grip the shaft, rub the tip."
Seoyeoni obeyed instantly. With a groan, she pulled back a bit, grabbing his pussy-soaked cock. Hesitating only a second, she spread her legs toward me like she was showing off and pressed it against her.
"Ah..."
Precum... pussy juice coated it, but something else glistened on his tip. She must not have noticed. She dragged the blunt head straight to her clit. No time to stop her.
