Ha, No Way I'd Lose to a Mere Dick
"S-Seo-yoon... you're acting kinda weird right now...! Hnng♡"
Mari desperately held back, fighting the scorching, slick sensation of her dick being gripped so tightly yet so softly, refusing to cum. If she loosened her tension even a little, it felt like her cock would immediately unleash a massive load. Even now, her balls felt like they were bubbling and boiling over. Her lower belly tingled, and her pussy—hidden beneath her balls—was drenched, soaking through her pants.

Whether she knew Mari was holding back with all her might or not, Seo-yoon seemed totally lost in sucking her dick. Her eyes were unfocused, not quite there—like she wasn't in her right mind. Chubop, churup, chuwup— watching her friend slurp away so eagerly at her cock was stimulation overload in itself. The elegant beauty Seo-yoon, now making lewd noises with saliva and precum drooling from her lips, gazing up while giving her a blowjob...
"Kang Seo-yoon, what the hell got into you...♡"
The taboo thrill of doing this with her best friend. The disappointment in herself for not rejecting it outright despite knowing she shouldn't, because it felt too damn good. And the exquisite pleasure of her friend's mouth-pussy on her dick. It was even more brain-melting than when she'd fucked Seo-yoon's pussy. The tingling ecstasy crawling up her spine pushed her right to the edge—just holding back from crossing that final line was her limit. A dark urge bubbled up: grab those soft locks, seize the back of her head, and ram deep into her throat.
All she could manage was gripping her shoulders to keep her from going deeper.
"Hnnng, haaaaa♡"
Seo-yoon, who'd been looking up at her, paused and slowly pulled her mouth off. The sudden emptiness and cool air left a hollow ache, but Mari sighed in relief—finally, she'd let go.
"Haa, haa... that was close..."
Just as she caught her breath, Seo-yoon seized the moment and plunged Mari's cock deep into her throat.
* * *
Mari's cock shot straight down my throat in an instant, roughly scraping my uvula as it went. I tried my best to swallow without gagging, but it was too thick—unavoidable. I couldn't help the gulk, glurk sounds as I took it all in, and Mari grabbed my head.
Oh, so that's why deepthroating always makes you gag like that? Doing it for real, there was no way to stay quiet. Unless it was super thin or too short for deepthroat, everyone probably made those noises.
The thick shaft pressing into my esophagus made breathing tough, but it came with a strange sense of security. A quick glance showed the call had ended long ago—Mari must've hung up, unable to hold back anymore.
"Wh-what's gotten into you, Seo-yoon...!"
"...?"
"Just hold on. Pull it out first, then we'll talk... got it?"
She carefully gripped my head and started lifting it slowly. Oh, but right now it's filling my throat completely, so pulling out like this...
"Hngk, huuung♡"
It was squeezing so tight—forcing it out must hurt like hell. She was still holding back her orgasm, precum steadily leaking from her urethra, sliding down my esophagus. No matter how trained a woman's pussy is, it can't squeeze or suck like a mouth, so this must feel totally alien. Even if I'd been practicing solo, I hadn't done hardcore lower-body workouts like a pro, so of course my mouth clamped tighter.
"Haa...♡ Hnng, Seo-yoon, let go for a sec...!"
Judging that forcing it out might make her blow her load in my mouth, Mari gently stroked my cheek and said.
Hmm, did I go a bit overboard with the teasing? I hadn't planned to go this far, but her reactions were so cute, I kept thinking just a little more... A bit regretfully, I slowly lifted my head.
Tzubooop— The cock that had filled my mouth and throat slid out. It bobbed wildly once it popped free.
"Heh—"
My jaw ached from holding something so huge, drool dripping down. I closed my numb jaw, wiped my lips, and the lingering scent of precum and faint semen hit me. Gulp. Swallowing, I felt the sticky mix of my saliva and her fluids slide slowly down.
"Haa, haa, haa... barely held back..."
Mari flopped back, covering her face as she panted.
"...You okay?"
Her rigid cock still twitched, spurting precum from the tip and running down the shaft. Oh, if we leave it like that, it'll soak her pants. Thinking that, I grabbed her dick and stuck out my tongue.
"K-Kang Seo-yoon, what are you—!"
Lick— I lapped up the clear precum glistening silver on the shaft, and Mari jolted in shock.
Ah, it's leaking more.
"You're weird today! What's wrong with you?!"
She grabbed my shoulders and yelled, her face beet red—adorable as ever.
"Seo-yoon, Seo-yoon, wait... hnnng♡"
Only after thoroughly licking her cock clean did I let go. Licking the remnants from my lips, my hazy mind cleared.
"Huh?"
What was I just doing? Sucking a dick? Her dick? Mine?

"Wh-what?"
The sticky traces on my hands and lips screamed it wasn't a dream. The musky precum and Mari's scent still lingered strongly in my mouth.
"Seo-yoon... you okay?"
Noticing I'd snapped out of it, Mari groaned and sat up, grabbing my hand.
While I'd been eagerly sucking her off, it felt like... like dozing off after a huge lunch, scribbling notes half-asleep, then finally waking up. You think you wrote diligently, but looking back, the handwriting's a total mess—barely legible. Like seeing your own sleepy scrawl and realizing, damn, I was out of it.
"I'm... okay now, I think."
"Hiiing, you scared me!"
She tackled me, knocking us both back, but I was just as stunned. I patted the embrace anyway—better calm her first.
"Sorry, I went too far with the prank."
"...Prank? That was a prank?!"
"I must've been possessed or something... I didn't mean to go that far."
Mari sniffled, looking up from my arms.
"...So you're good now? Not zoning out like before?"
I flexed my hand a few times. Seemed fine.
"Yeah, I'm good now. Sorry for worrying you."
"Seriously, I thought something happened to you! You have no idea how freaked out I was!"
She pouted and thumped my chest. Guilty as charged, I let her.
Hmm, I was just gonna tease her erection and poke it... But seeing her dick made me blank out and shove it in my mouth...
"Ughhh, I must be crazy."
"Yeah, you looked totally insane. Why'd you even suck it?!"
"Remember last time I said I'd do it with my mouth once?"
"...Huh? Oh yeah..."
"Guess that promise stuck in my subconscious."
"So you went nuts and sucked mine when you weren't thinking straight?"
She sniffled again.
"Seems like it. Seeing your dick out of your pants just... hit me."
"What? Then...!"
She yanked up her pants, clutching the waistband tight.
"You gonna do it again if you see it?!"
"Doubt it..."
"No way, better safe! Gotta be careful."
"But it didn't happen before yesterday. Something must've changed, right?"
"Hmm..."
We huddled, brainstorming, but nothing screamed this is it! No condom? We'd gone raw the first time—no issue. Clothes on? We'd have fucked in the department store fitting room. What then? Nothing clicked...
"Ah. Wait."
"What? Hit on something?"
"We didn't air out the room today."
"Huh?"
"We fucked yesterday, passed out, then ran the laundry at dawn."
"Yeah...?"
"But we never opened the windows."
"...For real? That's why?"
"Wanna test it?"
Mari swallowed hard and cautiously pulled out her dick again. The thick, musky male scent hit like a wave—my mind fogged instantly. My body didn't feel like mine. I reached instinctively, but she dodged, jumped up, and flung open the window.
Whoosh! Cool air rushed in. I blinked, and the sticky haze cleared as fresh air filled the room.
"Wh-whoa... yeah, it's the window."
"Seriously, the smell?"
Mari muttered, her dick swinging as she stared in disbelief. Same here.
No way I'd gotten high off her dick smell? That night-flower stench?
"Ughhh..."
"What's wrong, Seo-yoon?"
"...Embarrassing."
Pfft, Mari giggled and sidled closer. Peeking past my hand, her still-hard cock glistened with my saliva. But no urge to suck it now.
Ah, fuck... really the smell? Do futanari dicks have aphrodisiac pheromones or something?
"We gotta air out every day."
"Yeah, no matter how cold."
We snuggled under the blanket, closing the window after 30 minutes.
"I'm gonna wash up quick."
"Huh? Why...?"
"...Your spit all over it, duh?"
"Oh."
"Or wanna join? I'll scrub your back..."
