Master's Cock, Stamped with My Lips ♥
Master's cock♥ I left tons of lipstick marks all over it♥ It's mine now♥
The cock was the male sex organ, the tool that ejaculated semen to make babies. When stimulated or sexually aroused, the once-soft spongy tissue would harden into an erection, and thrusting that erect cock into a woman's pussy—the female sex organ—for ejaculation was copulation, the way to make a baby. Every human was born this way, so you could say the cock was the starting line of life.
Saying it like that might make the cock sound like some sacred body part, but in reality, it was anything but holy. It was the organ that peed, and in its sweaty confines, it was prone to smelling. Among a man's body parts, the cock was one of the filthiest, which made the very idea of sucking it on nauseating just to think about.
That should have been the case. Yet...
"Mmmph♥"
Yeon Wol pressed her lips perfectly against the tip of the cock—the glans, right on the urethra—her cheeks flushing a shy red with excitement. Hmm, what the hell was this? I'd told her to suck it, sure, but enjoying it this much was just weird.
Was it because she was a woman and didn't have the same hang-ups about cocks? For men, the cock was like a second self dangling between their legs from birth, but women didn't have that. It wasn't part of them, so they probably felt less aversion than guys who saw theirs every day.
Yeah, a meat stick that didn't belong on their own body—curiosity made sense. But to kiss it happily, with actual affection? No matter how I thought about it, that wasn't normal.
I didn't have a bad view of women's pussies myself, but if I had to suck one, I'd probably struggle. Pussies peed too, after all. Gleefully pressing the hole you ate with against the hole that pissed and fucked? I just couldn't wrap my head around it.
"Slurrrp...♥ Pwah♥ Haaah♥"
And yet, Yeon Wol was doing this incomprehensible act with pure delight.
"Ahh. If I'd known I'd get to suck Master's cock, I would've put on some lipstick. Then I could've stamped Master's glans and claimed it as mine..."
After planting a deep, genuine kiss on my glans, Yeon Wol pulled back but stared at it longingly. Then, as if struck by inspiration, she gasped "Ah!" clapped lightly, and looked up at me.
"Master! Can I go put on some lipstick and come back to kiss the glans some more? There's no rule saying it can only be once, right? So I can do it again? Yeah?!"
Our goal here was to test if semen ejaculated into her mouth via oral sex could suppress her magic. Whatever Yeon Wol was suggesting with those sparkling expectant eyes was pure time-wasting, irrelevant to the experiment.
"...Fine, go ahead."
"Yay! Master is the best! I love you, Master!"
But I couldn't refuse her pointless detour. Her "glans kissing"—an act that utterly transcended my understanding—had shown me the depth of her feelings for me.
How much did she like me to gaze at this filthy cock so lovingly and kiss it like that? The emotions she'd been showing me since yesterday were something a master should never accept, but right now, we had no choice but to share intimacy.
So, using this unavoidable situation as an excuse, wasn't it a master's—no, a man's duty—to grant her wish, if only for a moment?
"Mmm! All done! Master, I'm ready!"
Lost in those thoughts, I looked down to see Yeon Wol already back, lips painted a vivid red. She knelt gracefully on the floor, gazing up at me with shining eyes.
"G-Good. You're ready."
"Yes! Then, from now on, I'll cover Master's cock with my lipstick marks! Ehehe♥"
With that, Yeon Wol gently closed her eyes, placed her hands demurely on her knees, straightened her back and shoulders, and exuded a refined air. The tomboy who'd seemed so childish moments ago now radiated mature elegance, like a bride on her wedding night. For a second, the Yeon Wol before me didn't feel like my disciple at all.
When did this girl learn to pull off such an adult vibe?
"Chuu♥"
Caught off guard by her sudden poise, I startled as she leaned forward just enough to plant a shy, deep kiss on the glans. The red lipstick transferred perfectly, leaving a clear mark. She slowly opened her eyes, saw the vivid print, and grinned ear to ear.
"Haaah♥ It's like a dream...♥ Master, now I'll fill in the rest♥"
Declaring it, she lifted her hands from her knees and gently cradled my cock.
"Chuuut♥ Chu♥ Mwah♥ Smack♥ Mwah♥"
Handling it like a priceless treasure, she kissed from the sides of the glans down the shaft to the balls, stamping every inch with her lips.
"Chuuuup♥ Pwahhh♥ Haa♥ Haa♥ O-Oh, the right side too♥ Th-Then the left toooo♥ Chuu♥ Chu♥ Smoooch♥ Chuuuup♥"
Finishing one side, she shifted to the other, plastering the rest with prints.
"Mmmph... Pwahhh♥ Haa♥ Ngh♥ M-Master's cooock♥ I left lipstick marks everywhere♥ It's mine nooow♥"
Finally, she planted the deepest kiss on the left ball, then gazed at my now lipstick-covered cock with hazy, unfocused eyes.
Her words were blatantly Gisamyeoljo—something a master should scold harshly—but I couldn't bring myself to.
"Huuu... Yeon Wol. Open your mouth."
After a full ten minutes of her love-filled kissing marathon, my cock had reached its limit. I was a man with a cock before I was a master, and her onslaught was too much to endure.
"Eh? Master just called me by name..."
"Open."
Our immediate goal was ejaculating into her mouth to get semen inside her, so I cut her off with a low command.
"Hng! Y-Yes, sirrr♥ Aaaah♥"
Without even wiping her saliva-drenched lips from all the kissing, Yeon Wol stuck out her cute pink tongue and opened wide. Even placing her hands back on her knees demurely—every move was lethally seductive, enough to make me forget my position as master.
My cock, pushed to the brink, raged. I grabbed her head with both hands and shoved it into her gaping mouth.
Schlup!
"Mmph♥ Slurp♥ Sluuuurp♥"
The moment it entered, Yeon Wol didn't flinch in surprise—instead, she sucked eagerly, like she'd been waiting. Looking down, I saw her cheeks hollowing, then her eyes rolling up to meet mine as she bobbed.
"Hng♥"
Our eyes locked, and she flashed a pure, beaming smile—the innocent one my disciple always gave when seeking praise.
She'd been acting so grown-up since the lipstick, insisting I treat her like an adult, and now this childlike grin...
...Damn it.
Her mature aura had lulled me into forgetting my place for a moment, but that smile snapped me back. I was the master, she the disciple. A bond like family, where even a heartbeat of desire was forbidden.
But realizing it was too late.
"Ngh, I'm cumming...!"
My cock had been at the limit for ages.
"Hngg♥ Mmmph♥"
At my signal, Yeon Wol gripped my thighs tight with both hands. She clamped her lips around the shaft, pulled back slightly, and licked the underside furiously to push me over.
Spurt, spuuuurt—!
The cock, maxed out beyond endurance, unleashed all the pent-up semen.
"Hwoong?!♥"
Her cheeks ballooned from the volume, her body trembling in shock.
Gulp.
Gulp.
Gulp.
Gulp.
But the surprise was fleeting—she swallowed every drop perfectly, even with my cock still in her mouth, throat working smoothly.
"Sluuuurp♥ Pwahhh♥"
Only then did she bob her head to clean the spent cock thoroughly before pulling off.
"Haa♥ Haa♥ Nghhh♥ Master's semen♥ It's so thiiiick♥ Feels like I'll get pregnant down my throat, Master♥ Ehehehe♥"
She'd cleaned it spotless, not a trace of saliva left, then looked up with that same praise-seeking smile.
"...Good job, disciple."
What else could I say? As her master, I had to praise her... cock-sucking skills.
