Only for Euna
She kept working her throat, swallowing down every drop of cum I fed her.
I'd already come more times than I could count, and still her balls hung heavy and swollen, stuffed full. Her cock would soften for only a moment before going rock-hard again the instant I hollowed my cheeks to suck out whatever was left lingering in her urethra.
"Khnn…♡"
A healthy cock and Euna's stamina, though, were two very different things. She curled in on herself, cradling my head, and the weight of her body forced her cock even deeper into my mouth. I had no choice but to take it.
No choice at all.
— Chuuuup…♡
I pursed my lips and suckled just below the middle of her shaft. She was simply too big — any deeper was impossible.
"Kh-hup♡ Eub♡ Ooogh♡"
That fat glans kept battering against the back of my throat. Every time I lifted her cock with my tongue, the way it twitched inside my mouth felt almost cute. Breathing was getting harder. A gag reflex rose unbidden.
"Sorry…♡ Sorry, Senior…♡"
She kept apologizing, but she made no move to pull away. That frantic edge in her voice only satisfied me more — it meant my mouth-pussy felt that good.
Tears squeezed out of my bloodshot eyes. Spit spilled from between my parted lips. I drank the precum leaking from her slit.
— Churrrr…♡
My breath trembled. My shoulders shook with a joy I couldn't contain. Still holding her cock in my mouth, I rose to my feet. It was a little awkward because of Euna, but even that awkwardness felt good.
Once I had a bit more room, I stripped off the skirt and panties that had only been getting in the way. My soaked panties clung so tightly that peeling them off my hypersensitive pussy nearly made me come right there. A shiver of pleasure sent my vision tilting halfway upward. The damp, stifling heat of my inner flesh met the cool, dry air with raw sensitivity. My body flinched on its own; my toes curled.
This time I didn't kneel — I carefully bent forward. My legs spread wide, and the cute pink flesh of my pussy was on full display, drooling strings of spit.
— Chuuuuuup…♡
The new position let me take her cock more comfortably. Just shifting a little higher made everything so much easier. The deeper her cock pushed into my throat, the more hypersensitive my untouched pussy became. My hips rocked up and down, forward and back, without thinking.
"Eub♡ Eugeuk♡ Eueub♡"
As if I already had a cock inside me. As if I'd confused the one in my mouth for the real thing. The rebound of every hip-thrust etched itself through my whole body, and a stream of fluid spurted out of me unbidden. Warm pussy juice soaked the sofa and Euna's cock.
When I'd been giving her a titjob, it had only been a teasing itch — nothing close to orgasm. Now I came, pathetic and pitiful, long before Euna's cock ever did. So shabby and filthy I couldn't even call it climax. As if my own body were proving that all I was good for was sucking cock — that I had no business putting on airs.
Euna must have seen the vulgar display, because I heard her soft laugh. She rolled her hips gently, tapping lightly against my throat.
"Ooogh♡ Oooogh♡"
"You like sucking cock so much you're shaking your hips too? Senior, you're so cute…♡"
As she said it, she reached out and began kneading my ass. The Euna who'd been completely swept away by me since the car ride was reclaiming her composure. Realizing she wasn't the only one coming so pathetically had put the strength back in her voice.
— Kwaaaak…♡
"Heup—♡"
Her long, slender fingers dug mischievously into my soft flesh. I felt my pussy lips, which had been pressed shut, flare open. A lewd wet sound — tseuup, tseuup — rose faintly. My pussy, which had only ever felt Euna's tongue, was clenching around empty air, masturbating all on its own. Contraction and release, over and over. Every time my womb throbbed, my tongue greedily sucked harder on her cock.
Whether she noticed the change or not, Euna's fingers crept deeper between my ass cheeks. Past that secret place, she pushed her middle finger inside.
"Wow… it's so hot…."
She murmured in quiet awe, then pushed her index finger in alongside it. Over my plump pussy lips, she pressed down firmly with both fingers.
— Tseuup♡ Tseuup♡ Tseuup♡ Tseuup♡
Like a baby bird begging for food, the inside of my pussy opened its mouth and drooled. Euna's fingers had caught my pussy in the act of craving cock. My face burned with sheer humiliation. Was this how Euna had felt when I was the one doing it to her?
— Kkuuk♡ Kkuuk…♡ Tseuueup♡
"Augh♡ Heup♡ Heut♡"
Her two fingers pressed and pressed against my pussy lips — then suddenly shoved inside. The unfamiliar pleasure of being stirred from within. My breath grew tighter, my head went hazy, and only my mouth and my pussy remained razor-sharp with sensation.
— Tseugeok♡ Tse-geok♡
Euna crooked her fingers into hooks. They'd been thin enough, being a girl's fingers, that I could endure it — but not anymore. In an instant they felt twice as thick, and my clenching vaginal folds scraped themselves raw against the angular joints. The moment she churned her fingers like she was scooping water from a well, love juices gushed out in a rush. Above and below, I was tossed back and forth between pain and pleasure.
Time seemed to flow thick and heavy.
"Hueuk…♡ Hueuk…♡"
I'd completely forgotten about sucking cock. Every nerve I had was locked on Euna's fingers. I pulled my hips back, lifted my ass, and offered it up so she could touch me more easily. Her fingertips prowled through my folds, hunting for my weak spots. I rolled my hips gently, showing her myself where it felt good.
"Heugeut♡ Eueub—♡ Eut—♡"
The instant her fingers pressed hard on that spot, my whole body shuddered and I squirted. For a long while after that, Euna simply played with my pussy. I climbed onto the sofa, kneeling and curling up so she could reach me easily. My mouth serviced the head of her cock with wet licks while my pussy climaxed for her pleasure.
"Heut♡ Heut♡"
— Bueeeuk…♡
Euna arched back languidly and came. Her arms and legs stretched out like she was waking from a nap, then went slack. Having made a full dinner of Euna's cum, I was starting to wear out myself. Of course I was. From the moment we'd gotten home, we'd been coming and climaxing without a single break. No wonder there was nothing left in the tank.
"Senior, want to rest a bit…?"
"Yeah…. Ah, my mouth is completely numb…."
I laid my head on Euna's lap and gave my lips a little shiver. Her long cock rested across my face. I puckered my lips sideways and playfully kissed the shaft.
"That tickles…."
Euna laughed softly and poked my belly.
"Hm…?"
After poking it, she spread her hand and gently stroked. Looking at my swollen, rounded stomach, she let out a little gasp of wonder.
"Is all of this my cum?"
"Yeah. All your babies."
When I rubbed my belly with affection, Euna looked down at me with eyes full of complicated thoughts. I couldn't begin to guess what she was thinking, so I stretched my lips out and kissed her cock again.
"Want me to suck it some more?"
"…No. This time…."
Euna carefully laid me down and climbed lower. She grabbed a cushion and slid it under my lower back.
"Ah…."
"Honestly, I feel like I'm about to collapse for real… so just one last time."
"Okay…."
I nodded blankly. Euna carefully spread my legs and stroked her cock quickly until it stood rigid again.
"Hoo… hoo…."
Whose breathing was that? Unlike before, the air was thick with tension, filling the quiet living room.
"……."
Euna angled her cock for entry. I thought she was about to push in — then she paused, the corner of her mouth lifting, and rested it with a soft thud right on top of my clit.

I understood her intent immediately and lifted my head just enough to look down. Her cock, drooling precum, looked like a starved beast with all those angry red veins. Propping myself up on both elbows, I struggled to shift my hips, trying to line her glans up with my entrance. The way my painfully swollen clit brushed against her cock felt so good. A sharp jolt of pleasure raced up my spine and into my brain.
"Ah…♡"
My face flushed red. I forgot the original goal entirely and prioritized what felt good for me. Using her raised veins against my folds, treating my clit like a tiny cock of its own, I started fucking her however I pleased.
"Heuut? Heuup♡ Ogh♡"
My lips rounded; heated breath and dumb little moans spilled out. It was a pathetic face, intelligence long since gone. But more than the shame, a vulgar craving rose up strong — I wanted to rub against her more, more—
"Senior, you're so cute♡"
Euna smiled with her eyes. That "cute" almost certainly meant the same thing as "dumb." The way my pupils rolled toward the bridge of my nose, the way I was grinding my clit on her cock — even just imagining it, I knew how stupid I must look. My mind could still coldly objectify myself like that, but my body had no intention of stopping.
"Senior, are you just going to keep feeling good all by yourself?"
"Sorry, I'm sorry…♡ Aeut♡ Eut♡ Rubbing my clit♡ feels so good♡ I keep turning into a total idiot…♡"
I deliberately let go of my sanity and raised my voice like a real idiot. I could faintly feel the sadism taking root inside her, spreading deeper. The dumber I looked in Euna's eyes — the more she liked watching me like that — the more masochistic pleasure tingled down my spine. My throbbing womb, beating gung— gung—, submitted to the glans pressed against my skin and sank lower and lower.
"Mm… at this rate we won't get it in your pussy all night… want me to put it in for you?"
"Yes, yes♡ Your cock, please put your cock in my pussy…♡"
As proof of my submission to her cock, I raised my speech. Lowering myself like that made a silly grin spread across my face.
"Then… you know what you have to do, right?"
"Yes, yes♡ I kn-know♡ Your cock, in my pussy, haeuk♡ Eut♡ Aht♡ Just a second♡ When you press my clit with your glans…♡"
"You don't like it?"
"Nngh…♡ Press, press… it feels g-good♡ But I can't t-talk—♡ Haeuk♡"
My clit was being ground into the hollow underside of her glans. Caught against the ridge of her cockhead, it twisted and mashed in strange directions. I came lightly, spraying a stream of fluid across Euna's thigh, and for a brief moment my brain cleared. Desperate to stop her from tormenting my clit any further with that glans, I blurted out whatever came to mind.
"G-Gaeul's pussy wants her girlfriend's cock…♡ Gaeul's virgin pussy, she became a girl just for Euna, got soaking wet just so Euna could fuck her… please put your cock in Gaeul's virgin pussy…♡ Heuut♡ Heeek♡"
"Okay. Thank you, Senior. For giving me your virgin pussy. For becoming a girl for me…."
Euna covered my body, kissed the corner of my mouth softly, and pushed her cock into my pussy.
— Chubooooop…♡
"Oooogh?!♡♡"
— Chueup chueup chueup chueup♡♡
Ah.
Gaeul's virgin pussy.
I came the second it went in.
