Eldest Sister Baek Yuna (Part 10)
"Slurp, slurrrp...♥"
Hmm? What's this?
"Suck, suck, suck...♥"
My dick felt amazing first thing in the morning. Was I dreaming?
"I love eating dick right after waking up..."
I felt a soft sensation caressing my shaft. Something soft, plump, and wet was persistently rubbing against my glans, making my cock throb with a dull ache. The sheer pleasure of it jolted me awake.
Sluuuurp...♥
"..."
"Mmh, slurp, slurp...♥"
Squinting my eyes just a fraction, I saw Yuna, who had fallen asleep in my room last night, greedily sucking on my cock. She was so entirely focused on my dick, completely ignoring whether I was awake or not, that it was actually adorable.
If you passed her on the street, she was an overwhelmingly gorgeous woman—so stunning and coolly expressionless that you wouldn't even dare strike up a conversation. And yet, here she was, giving her little brother's morning wood a thorough cleaning first thing in the morning.
As a reward, I decided to gift her a generous helping of her favorite treat: my semen.
Spurt. Spurt.
"Slurrrp...♥ Gulp... gulp..."
Listening to the ASMR-like sound of her swallowing my cum, I closed my eyes and continued to play dead.
"Ah... it's so delicious... Little brother, are you asleep?"
"..."
I kept my eyes shut, committing to the act. With my eyes closed, the sensations on my cock became even more vivid. Ah... Was she taking my glans into her mouth while lightly scratching my shaft with her fingernails?
The overwhelming pleasure radiating from my tip, combined with the ticklish, dizzying sensation tracing the veins of my shaft, was intense. I could picture her in my mind, being so careful not to scratch her precious brother's cock.
As if she had figured out that targeting the glans was the most effective way to milk a man, she persistently sucked on the tip.
Suck, suck, suck...♥ Lick, lick...♥
Her soft lips constantly rubbed against the ridge of my glans while her tongue swirled over the slit. Before I knew it, her hand was wrapping around the shaft, stroking it up and down to pump the semen up from my balls.
Squelch, squelch...♥
My entire cock was slick and wet from the saliva spilling from her mouth. I had no idea a morning blowjob could feel this incredible. I'd have to make this a daily routine from now on.
I wanted to wake up right then and there to ravish my wicked sister, but I was too curious to see just how far she would go while she thought I was asleep.
Spuuurrrrt!♥
Fueled by the raw power of my morning erection, a thick torrent of semen shot straight down her throat.
"Slurrrp...♥"
Even while swallowing the cum, she kept tickling my urethra with her tongue. The pleasure radiating from the tip of my dick shot straight to my brain, prolonging the ejaculation.
I peeked through my eyelashes again. Yuna was masturbating while happily drinking down my seed. No wonder the sweet scent of blueberries was filling the room.
"Mmh, I love fingering my pussy while sucking my sleeping brother's cock...♥"
Yet, her expression still seemed somewhat unsatisfied. After being stretched out by my thick, massive cock late into the night, there was no way her slender fingers could satisfy her now.
"Is it okay to have sex with him while he's asleep?"
Yuna formed a ring with her thumb and index finger, stroking my glans rapidly as she debated with herself.
Stroke, stroke, stroke...♥
I figured I should help ease her dilemma.
"Mmh... Nnh... My cock is so cold..."
"...! D-Did you wake up?"
Her shoulders flinched as she asked, though her hand didn't miss a beat, continuing to stroke my tip with practiced ease.
"Mmh... My dick is freezing..."
"Your dick is cold? We can't have that!"
Yuna tried covering it with the blanket, then tried wrapping both of her hands around it. When she realized she still couldn't fully cover my massive shaft, she took it back into her mouth, using her warm tongue to raise its temperature.
"Nnh... It's still cold..."
"Still cold? What should I do?"
She was genuinely panicking, worried my cock might catch a cold. Then, a thought struck her.
"Ah... the warmest place."
It seemed she had realized where the warmest part of her body was.
"This is... for the sake of my little brother's health."
Having successfully rationalized her actions, she lifted her hips and began rubbing my shaft against the entrance of her pussy.
"Ahnn... Sex first thing in the morning... No, wait. This is medical care, not sex."
Rub, rub...♥ Squish, squish...♥
To make sure it wouldn't hurt, she generously coated my shaft with the copious amount of sweet juices overflowing from her pussy.
"Let's get you nice and warm, okay?"
With that, she lowered her hips.
Sluuurp!♥
"Haaahhh...♥! ...Mmh!"
She almost let out a loud moan, but quickly clamped both hands over her mouth when she remembered I was supposedly asleep.
"Ah... your cock is so warm now..."
"Thank goodness. I knew a pussy massage would do the trick!"
With a look of genuine relief, Yuna collapsed her slender body onto my chest, clinging to me tightly. Even as she lay still, her tight, shape-memory vagina was instinctively pulsing and squeezing my shaft, sending waves of pleasure through me.
"Haaah... I feel so full. My brother's cock is the absolute best."
Just having her hold my dick inside her felt amazing, but I wanted more. I wanted her to squeeze and milk me with everything she had.
"My dick is still cold..."
"...!? Still cold? Then there's only one thing left to do."
After a moment of hesitation, Yuna placed her hands on my chest with a look of firm determination. Careful not to wake me, she slowly lifted her hips and slammed herself back down.
Squish!♥
"Mmmgh...♥!"
Even though her hands were resting on my chest, I barely felt any of her weight. Even when my cock buried itself deep inside her, her pubic bone didn't press down on me at all.
Squish, squish, squish, squish...♥
She was riding my cock like a drop tower, relying entirely on the strength of her thighs. Up and down she went, with the sole destination of pussy-clenching climax—a custom-made amusement park ride just for her. She bit her lip, trying her best to suppress her moans, but it was futile against the relentless friction.
Squish, squish, squish, squish...♥
"Ah, nnh... Ahnn, I'm supposed to be nursing his cock... but... haah...♥ My pussy loves this too much...!"
"Mmh... My dick feels so good..."
"Ahhh...♥ No, little brother, no...! If you keep fucking my pussy in your sleep... ah, nggh, you're going to drive me completely wild."
Still pretending to be asleep, I made sure to let her know how good it felt, subtly thrusting my hips in sync with her rhythm. Firmly believing I was dead to the world, Yuna continued to whisper to herself.
"Your cock is amazing... It knows exactly where my sweet spot is...♥"
Squish, squish, squish...♥
"Ahhh♥ It's getting even bigger...! Are you going to cum? Are you going to shoot your warm milk inside me?"
"I think I'm gonna cum..."
"Ahnn, yes, shoot it... Let's keep your cock healthy by filling me up with your thick, warm cream."
She pressed herself flat against me, making sure I felt none of her weight, and began whispering words of encouragement right into my ear. Had I really corrupted my pure, innocent sister into such a submissive female? The sheer, forbidden thrill of it threatened to melt my brain.
"It's coming... It's coming...!♥"
Spuuurrrrt!♥
"Ah, nggh... Ohhh...!♥"
Her thighs trembled violently as she absorbed the hot blast of my semen, her hips twitching uncontrollably. She clamped her hand over her mouth, desperately trying to stifle her cries—a testament to her sweet, caring nature. By now, she really should have realized I was awake. She was just too adorable, so I wrapped my arms around her and pulled her close.
"Hic...! Little brother, you're awake?"
"Mmh... Nnh... Make me feel even better."
I kept up the sleeping act.
Plunge, plunge, plunge...♥
"Ahhh, nggh! Don't ravish your sister in your sleep...!♥"
"I love your pussy."
"Haah...♥ Haah...♥ I... I love your cock too...!"
Holding her long, model-like body in my arms as I thrust up from below, she looked like she was in heaven. Every time I whispered how much I loved her pussy in her ear, her tight walls clamped down hard in response.
"I'm cumming."
"Mmmgh...♥ Shoot it! Fill your sister's cum-dump of a pussy with your seed!"
Gush, gush...♥
My glans, pressed flush against her cervix, unleashed another thick torrent of semen.
"Ahhhhh...♥!"
Yuna climaxed hard as the hot semen battered her womb. Her tight walls kept squeezing, which only made my cum keep flowing. I felt so blissfully happy, I wished I could ejaculate forever.
"Jihan, wake up. I know you're awake."
"Huh? You knew?"
I opened my eyes fully, admiring her face which was completely flushed and melted with pleasure.
"Since I first started sucking you."
"How did you know?"
"The scent of your cock changed."
"Heh, you really are a certified expert on my cock's scent."
I playfully licked my lovely sister's ear.
Slurp, lick...♥
"Why did you pretend not to know?"
"Haah...♥ Because it seemed like you wanted to play along."
"Who's a good girl? You're so sweet."
I gently stroked her hair. As I continued to caress my beautiful sister from head to toe, her pussy, which was still clamped around my cock, twitched petulantly.
"D-Don't do that. I'm your older sister."
"It's just because you're so beautiful."
"R-Really?"
Yuna ground her hips, teasing my cock for a moment before settling down again.
"Haah... I feel like I have the whole world."
"Me too."
Her warm, heated body felt incredible against mine. Like a cat purring in a sunny spot, she let out soft, ragged breaths while keeping my cock buried deep inside her. Hearing those sweet pants made me want to start thrusting all over again.
"Yuna."
"Yeah?"
"One more round is fine, right?"
"I'd love to...♥"
This was one of the many perks of succubi. No matter how hard or how long you fucked them, their bodies never wore out. Would I ever feel this kind of satisfaction from a human woman? Would I get this same incredible sensation if I bedded the women of the Cheon Family, the natural enemies of succubi? I didn't know yet. But I would find out soon enough.
"Ah... Yuna, your pussy is so tight. It's seriously the tightest grip in the universe."
"Ahhh...♥ Jihan, your cock is the absolute best too."
It had felt amazing the very first time, but our compatibility only seemed to grow with each session. I wasn't sure if my cock was adapting to her, or if the succubi's vaginas were adapting to my dick. Well, whatever the case, a win was a win.
Squish, squish, squish, squish...♥
"My cock...♥ Please, fuck me harder...!!"
We continued to have wild, passionate sex until Anna eventually called us down for breakfast.
