Aunt Baek Serin 4
My aunt looked gorgeous in absolutely anything she wore. But without a doubt, her best outfit was her birthday suit.
Her massive breasts that couldn't be held in a single hand, her plump, juicy ass, and her thick, fleshy thighs didn't sag in the slightest, maintaining their perfectly beautiful shapes.
Because of that, dressing her up for sex was purely for a change of pace—nothing more, nothing less. Though, of course, she pulled off every outfit flawlessly.
My reason for asking her to cosplay this time carried that exact level of casual expectation.
But... why the hell was I getting so incredibly turned on?

My aunt was perched on the edge of the bed, her hips lightly resting on the mattress as she mimicked a cute little bunny.
Black fishnet stockings hugged her shapely legs. The soft, plump flesh bulging slightly through the diamond gaps triggered an overwhelming urge to suck on them.
A V-shaped strip of pink fabric barely covered her from her pussy up to her breasts, and the bow tie around her neck served as the perfect cherry on top.
Even the cheap, slightly crumpled bunny-ear headband looked adorable on her.
In short, she looked fucking hot.
"How do I look?"
"..."
"Why are you staring like that? You're making me blush... Is it bad?"
As I stood there dazed, scanning her up and down, my aunt spoke with a self-conscious expression.
Seriously, how could I ever get used to these succubi? Every single day brought a new flavor of temptation, and they only seemed to grow more beautiful by the hour.
Like an onion, no matter how many layers I peeled back, they always revealed a fresh, captivating charm.
"...No... you just look too beautiful."
I barely managed to squeeze the words out. The rush of heat to my head surged back down through my body, making my cock rock-hard.
Throb, throb!
I wanted to plunge right into my aunt's bunny pussy this very second.
Seeing my furiously throbbing cock and my flushed face, my aunt smiled seductively and crawled closer.
"Do you know what a bunny's favorite food is?"
"...What is it?"
When I tilted my head at the sudden question, she dropped to her knees right in front of me.
"Carrots, of course. Carrots. Haa... but look what we have here. The biggest, most delicious carrot in the whole wide world."
Rub, rub!
Sniff, sniff!
Lifting my cock with her delicate hands, she buried her face right against it.
"Haa... Darling, can your bunny wife eat your massive carrot? Can I have a delicious bite?"
"Just how deliciously are you going to eat it?"
"Sniff, sniff... sniff... haa, it smells so good..."
My aunt sniffed at it as if she had truly transformed into a rabbit. Letting go of my shaft, she nudged and rubbed her face against it, her sharp nose sending my cock swaying back and forth with every twitch.
She didn't even answer my question, completely lost in her obsession with my dick.
"You're taking this way more seriously than I expected."
And here she was earlier, whining about how uncomfortable cosplaying would be.
"Doing things half-heartedly just makes it awkward for both of us. If I'm going to do it, I might as well go all out."
I nodded at her logic. Well then, should I get serious too?
"Time for dinner, little bunny~"
I fully channeled the role of a keeper taming his pet rabbit.
I teased the insatiable, greedy bunny—who could never eat her fill—with the extra-large carrot that only I could provide.
Sway, sway. I gently swung my cock in front of her eyes. Her lust-filled gaze tracked its every movement until, seizing the perfect moment, she lunged to bite it without even using her hands.
Whoosh! But she missed.
Instead, she caught my balls, sucking and mouthing them playfully.
"Haa, bunny. That's not the carrot."
"Then, slurp, what is it?"
"That's the factory that makes the carrot juice."
"If I suck here, munch... will more juice come out?"
"I'm not entirely sure about that... but if you suck on the tip right here, the juice my little bunny Serin loves so much will come pouring out."
"Then put the carrot in bunny's mouth... ahhn... ♥"
When I pointed to the glans, my aunt let out a cute, exaggerated gasp and opened her mouth wide.
I stared down into her mouth. Her wet, pink tongue flicked back and forth, practically begging for the carrot.
And deeper still lay her throat-pussy—shrouded in darkness, yet its tight, warm texture was incredibly easy to imagine.
I pushed the carrot into her mouth.
Her mouth wasn't particularly large. My fully engorged cock parted her plump lips, sliding deep inside.
"Mmmph... lick, lick... gulp!"
"Ah... this is insane."
The psychological thrill of being sucked off by a "bunny" sent an extra shiver down my spine.
Regardless of my admiration, my aunt was entirely focused on devouring my cock.
"Slurp, slurp, slurp..."
Swallowing me all the way to the root seemed a bit too much for her. Only the head and the upper half of my shaft were receiving the blissful treatment of her mouth-pussy.
Yet she didn't even use her hands to touch the rest of my shaft, seemingly determined to act like a real rabbit by using only her mouth.
"Slurp, suck... My darling... likes it here, right...?"
Her plump, soft lips clamped tightly around the glans, frictioning against my most sensitive spot.
"Ngh...!!"
While taking it deep to the root felt amazing, nothing beat direct stimulation of the glans when it came to pushing me over the edge.
My aunt, fully aware of this, relentlessly teased the head of my cock.
"Slurp, suck, slurp, suck♥!Phew... My darling's carrot keeps twitching so much, smack, smack, it's hard to suck."
"That's because my bunny is just too adorable."
"Haa... I-Is that so? Then I guess I have no choice."
I playfully brushed off her teasing complaint—which basically meant "keep still so I can suck you off in peace"—and continued to enjoy her intense blowjob.
She looked up at me through her lashes, gauging my reaction. It was so incredibly cute that I couldn't help but reach down and stroke her hair.
Slurp, slurp, slurp, slurp♥
Suck, suck, suck, suck♥
Ah, I was reaching my limit.
With her soft lips scraping over my glans multiple times a second, holding back was becoming impossible.
Her tongue swirling over my urethra, practically demanding my cum, only accelerated the process.
I tightened my grip on her hair, intending to pull her head closer to finish, but—
Slap! My aunt swatted my hand away, spun around, and crawled back onto the bed.
While my cock throbbed pitifully on the verge of spilling over, she lay back on the bed, spreading her legs wide and pulling aside the fabric covering her pussy.
Or rather, she tried to, but the sweat-slicked fabric clung stubbornly to her skin. Looking slightly embarrassed for a moment, she simply ripped the fabric apart and spoke in a sweet, submissive voice once more.
"Sucking your cock was so exhausting... bunny's battery is completely drained. Pant, pant. I think I need to put some fuel in here..."
My aunt clearly preferred receiving my cum in her pussy over her mouth. Or perhaps sucking me off had pushed her past her own limits. She went out of her way to play the exhausted victim just to beg for my dick.
Drawn to her pussy, which was already dripping with slick, wet juices, I reached out as if under a spell.
"Is this the fuel port?"
Squish, squish♥
"Mmm...♥ Yes, just pour the carrot juice right in there... Ah, don't tease me... put it in quickly...♥!"
My heart skipped a beat. I had seen succubi act cute when they were completely drunk on the pleasure of sex. But back then, I had always been half-crazed with lust myself.
Experiencing her acting this adorable while we were both fully conscious made my heart pound wildly.
To think I'd feel butterflies for my aunt. A rush of sweet, youthful hormones flooded my lust-addled brain.
"I have to do exactly as my bunny wishes."
"Not bunny..."
As I aimed my cock at her entrance, preparing to thrust, she demanded a correction.
"Call me... darling."
"Pfft...! Alright... Darling... I'm going in, okay?"
"Yes... my young husband."
Plunge!
"Ngh-ah... s-so suddenly...!!"
Though our conversation had been sweet, my cock craved nothing but filthy, raw sex.
In the blink of an eye, my shaft breached her entrance and buried itself all the way to her cervix.
Squish, squish, squish, squish♥
"Oh, your cock... is so deep...♥"
Slap, slap, slap♥
Her breasts, still partially bound by the fabric, bounced wildly in every direction.
Even under my brutal, heavy thrusts, my aunt held her own legs back, submissively offering up her pussy.
A devoted posture reserved solely for her husband. I absolutely loved it.
I did my best to reciprocate.
"Ohhh... th-this is insane...♥!!"
Rather than just pounding her hard, I ground my hips in a mesmerizing, rolling motion.
My excessively large cock scraped delightfully against every inch of her walls even with simple thrusts. But that didn't mean technique was useless.
Pulling out until only the head remained, I angled my shaft upward as I drove back in.
"Haaah... there... scrape me harder right there...!!"
With her textured G-spot thoroughly stimulated, my aunt squealed in ecstasy, her juices spraying out.
Squelch! Squelch! Squelch!
"Darling! I'm cumming!"
"Yes, darling... fill me! Fill your wife's pussy... with lots of your cum...♥"
My wife begged for my seed without a shred of shame. Anticipating the warm fluid that would soon flood her, she clamped her walls tightly around me.
"I love you!"
"Ohhh... I love you too...♥!"
Spurt, spurt, spurt...♥
Gush, gush, gush...♥
"The warmth is coming...!!!"
Shooot, shoot, shoot♥
Pressing my cock flush against her cervix, I blasted my load deep inside. Her pussy, desperate for my seed, opened her cervix wide to suck every drop of the hot cum into her womb.
"Ah... a creampie is always the right answer."
Even as I lay still during the ejaculation, her walls twitched and massaged my shaft relentlessly.
Not that I had ever used one, but I knew I could never use a condom for the rest of my life.
"...Oh, ohhh...♥!"
My aunt continued to moan off-beat with every heavy pulse of cum shooting into her.
And then...
Shhhhh. A grey mist began to drift from her body, signaling the onset of her Succubus Form.
"Darling?"
"..."
Squish, squish, squish♥
The thick, billowing fog completely obscured her body, but it didn't matter in the slightest.
My cock was still buried deep inside her pussy, and all I had to do was keep moving my hips.
"It feels like I'm fucking the air itself."
Squelch, squelch♥
But the sheer, overflowing wetness of her pussy quickly made up for that fleeting illusion.
