Since she was sweating so much, I decided to take off her babydoll. I had Misaki stay seated as I grasped the hem of the skirt and casually flipped it up.
"Ugh!"
Her full breasts bounced playfully, and Misaki let out a delighted squeal. The babydoll in my hand was damp, clearly showing how deeply she'd been immersed in what we'd been doing earlier.
More than anything...
"Your body, Misaki-senpai... it's truly beautiful."
With the indirect lighting behind her, Misaki's figure as she stretched her legs seemed almost ethereal, as if she'd wandered into a painting. Her softly flushed skin, dewy eyes, mischievous gaze, soft, pillowy breasts, and lush hair. If I leaned closer, I'd catch a sweet scent, and if I touched her, her skin would feel so warm it might melt.
"Hmm? R-really? Nfufufu..."
Misaki gave a cute, bashful smile and flopped back onto the bed.
"Ah, what should I do... If Kotaro takes me now, I might break..."
"I'll break you properly, don't worry."
Misaki's body, lying face-up, shuddered violently.
"K-Kotaro... Do... do you know what I just said...?"
She propped her head up, gazing at him with a mix of anticipation and anxiety.
"I know."
He leaned closer with a creak, making Misaki swallow audibly.
His fingers traced her plump thighs, gripped the back of her knees, and spread her legs, exposing her intimate area.
"Yaaan...!"
Misaki let out a kittenish whimper, covering her lower abdomen with both hands. Her voice trembled with shame, but beneath it burned a greater expectation.
He pressed his throbbing erection against her clasped hands.
"Senior Misaki, do you want it?"
The question was direct. Misaki's eyes darted nervously, then fixed on him with a shy, sidelong glance.
"U-um... I want it."
"Then beg properly. Don't hide this part either."
He gently poked her glans with slender fingers, and Misaki's lips moved restlessly.
Her neatly shaped eyebrows furrowed, and she softly moved the hand covering her intimate area. The vivid pale pink mucosa glistened with moisture. Not only did Misaki stop hiding, she gently spread her labia with her fingers, revealing the honey dripping from her.
Misaki's plump buttocks swayed seductively as she gave him a coy smile.
"Kotarooo... I want your big, hard, thick penis inside me...?"
Her voice, sweet as syrup, was the purr of a kitten. The sound melted into a soft mass that slid into his ears and invaded his entire body.
"...Alright."
Misaki's face filled with anticipation.
Alright, I'm going in...! The moment he thought this...
This time, I guess it's okay to be informal, right?
The words Misaki had spoken after dinner suddenly came back to me.
No matter how close we'd grown, the image of her idolized senior lingered strongly. That's why she'd always maintained formal speech with me.
But now...
"...Alright, I'm going in, Misaki."
"..."
Misaki's eyes widened in surprise. Trying to shake off my embarrassment, I pressed my cock against her entrance and thrust forward.
"Ngh...aaah...!"
A blissful moan escaped Misaki's lips. Her vagina was so warm and soft, so pliant.
This is bad... I'm gonna come too soon...!
But it wasn't just tightness. The soft folds of her inner walls clung to my shaft, gripping me so pleasurably that I worried they might tear me off at the base. When I braced myself, hands on the floor beside Misaki's shoulders, she gave a cute little "Huh?" and tilted her head.
"Kotaro? You have to put it all in."
"Huh... Ugh...?!"
Misaki's legs smoothly wrapped around his waist, and he suddenly connected to her completely.
"Ahaah... Kotaro's penis... it's all the way in...!"
She whispered happily into his ear, but Kotaro was desperately trying to hold back. He squeezed his inner thighs tightly to resist ejaculation, but a thick stream of pre-cum gushed out.
"Nyuh... Kotaro, you finally started talking back to me, didn't you? So manly and cool!"
She whispered gleefully, stroking his abdomen, sides, and back. Being teased by an older sister made him feel incredibly embarrassed.
"Don't tease me... It's not easy switching suddenly like this!"
"Mmm, right, right..."
Misaki chuckled gleefully, her eyebrows occasionally furrowing. Her trembling body, still connected to him, showed she was reaching climax again.
"Misaki... I'm moving."
"Mmm... Come."
Still in the push-up position, he withdrew his cock and thrust it back in with one swift motion, then abruptly increased his thrusting speed.
"Nghhhh?! Ah! Hia! Haaah! Uwaaaaah!"
Misaki's moans skyrocketed. Her soft body arched back, her hands affectionately stroking Kotaro's. As her slick walls powerfully clenched his shaft, Kotaro's eyebrows also furrowed.
"Misaki... Did you just come again? You're so damn slutty."
"Yaaan... It's just... being with Kotaro... it feels so good..."
"'Being with' isn't specific enough. Be more explicit."
"...B-being with Kotaro... having sex with you... it feels so good... Hiiiiin!"
The words that escaped from her small lips ignited a surge of sadistic pleasure. Still staring intently into Misaki's eyes, I sped up my thrusts even more.
"Ngh... Haaah... Haaaah...!"
Our slick, joined bodies were in a lewd position, visible to both of us. Misaki shook her head back and forth, moaning in protest, her back arching sharply as she reached another climax—how many times had she come now?
"You're so cute when you're writhing in pleasure, Misaki."
"Stop saying that... Ah... Haaaaah...!"
As I pinned her with my gaze and tormented her with my words, Misaki began to buck her hips, shamelessly grinding her pelvis against mine.
"Guh...?!"
The unexpected counterattack nearly drove me over the edge. The underside of my cock, angled upward, was mercilessly scraped against her inner walls, and her pre-cum spilled out in sticky spurts: bubi, bujururu.
"Ah... Mmm... It's so slippery and slick..."
Misaki's eyes narrowed in pleasure at the sensation of the abundant pre-cum, and she gently reached out to stroke her nipple.
"Guh... Ugh...!"
Even when I stopped moving, unable to take it anymore, Misaki's hand and hips kept moving. Her hips circled, tightening around my shaft, while her soft fingers caressed my erect nipple.
"Hmm? Kotaro, what's wrong?"
Misaki's mischievous grin and provocative gaze ignited a mix of irritation and sadistic desire within me. I grabbed the wrist she was caressing my nipple with, crossed her arms, and yanked her toward me.
"Uwaaaaah?!"
With a forceful thud, I slammed my cock deep inside her, silencing her bewitching counterattack. My primal instincts raw and exposed, I ravaged the body of the senior who was two sizes smaller than me.
Squelch, gurgle, thud, slurp.
"Mmmk... Ahh, fu... Nngh...!"
Misaki gasped, tears welling in her eyes. She might be exhausted from climaxing so many times. But I didn't stop. I didn't want to. I thrust my hips again and again, lost in the overwhelming pleasure, wondering why I hadn't yet come. The vulgar schlick sound of our bodies colliding echoed in the room, but I ignored it and kept moving.
"Ahhhhh... Ah... Ahhhhhh...!"
With a final slap, I stilled my hips. Misaki's mouth hung open, her pale belly trembling. Beads of sweat glistened on her dewy skin. Drops fell onto her, and I was drenched in sweat too.
"K-Kotaro..."
Misaki reached out her trembling hands. Overcome with tenderness, I lunged forward and held her tightly.
"Misaki, Misaki, Misaki..."
I press my lips to her small ear, calling her name over and over. Each time I say her lovely name, my heart swells with tenderness.
"Kotaro, Kotaro..."
Misaki's voice melts my ears. I thrust my flesh spear into her again and again, relentlessly. Inside her, I feel myself already melting into a puddle, the boundaries between where I end and she begins blurring into indistinction.
"Kotaro, I love you... I love you so much..."
"...I love you too..."
Words that would normally make my face explode with embarrassment now slip out, carried by our shared heat. I don't care how mortified I'll be later. Right now, I desperately want to tell her how I feel.
Misaki's slender arms stroke my back, her legs wrap around my waist, and she pulls me into a tight embrace.
"Kotaro... It feels so good... I want more of that firm, slightly rough penis inside me, thrusting deeper...!"
Thwack!
A sound like a thread snapping rang clearly in his mind.
"Misaki...!"
He hugged her small body so tightly it bordered on painful, thrusting his hips wildly. Their bodies were pressed so closely together that speed was limited, but each movement was powerful, sticky, and deliberate, driving waves of pleasure deep inside her.
"Ah, kaah...?! Haaah, Kotaro, I love this! Yes, more, more...!"
In rhythm with Kotaro's thrusts, Misaki rocked her hips. His cock was squeezed from tip to base, the overwhelming pleasure nearly making him weep. The coiling urge to ejaculate made his neck strain visibly.
"Misaki... I'm gonna come. I'm going to let loose...!"
"Mmm... Come inside me... I want Kotaro's thick, rich semen to fill me up, gushing and spurting...!"
A voice tinged with childishness uttered obscenities of unparalleled lewdness. A surge of tenderness welled up within me. Lust roared through my body. I wanted to come inside her, nothing more than to pour myself into her. Never before had I craved ejaculation so intensely.
"Ugh..."
My lower abdomen churned like boiling water. Like magma bursting through solid rock, the thick, impending release surged upward through my narrow urethra.
"Misaki! I'm coming, I'm coming, I'm coming, I'm coming...!"
"Kotaro, come here, fill me up... Ah!"
As I pressed the tip of my cock against her cervix, thick white fluid gushed out with a wet squelch. Misaki's voice cut off abruptly.
"Ah, ah, haaa... Ahh...aaah...!"
Splash, seep, gush, squelch, splatter, splatter, splatter...
"Ugh... Ah...!"
The pulsations of ejaculation intertwined with the clenching of her vaginal walls. The overwhelming climax forced his eyes shut tightly.
"Kotaro... Kotaro..." Misaki whispered hoarsely, her limbs entwined around him. Her expression and words were infinitely adorable, yet the relentless thrusts of her hips and the merciless contractions of her muscles around his white-hot, spurting shaft were brutally carnal.
Thrust, receive, pour, swallow.
The two of them spasmed incessantly, luxuriating in the endless cycle of pleasure.
Even after the pulsations of climax subsided, they remained tightly embraced. The only sounds were their ragged breathing and the occasional hum of the air conditioner. A slight shift of their bodies sent waves of sweet ecstasy from their joined flesh, causing their brows to furrow in unison.
"Misaki..."
"Mmm... Kotaro..."
Smack, smack, smack... They kissed over and over. They whispered words of affection into each other's ears, then kissed again.
"Ah... Huh? Ah, fwaa... Huh?"
As Kotaro began to sway his hips languidly, Misaki giggled cutely, her eyes unfocused with pleasure.
"Nyuh... Kotaro, you're such a pervert."
"Not as much as you, Misaki."
"Nyuh... I wish I could talk to you casually like this. You're so cool, Kotaro."
The sincere compliment made his cheeks soften into a smile.
"Kua... Huh?"
In rhythm with Kotaro's unhurried thrusts, Misaki ground her hips against him, her pelvis rubbing against his.
"I want to stay even closer to you, Kotaro. Can we do it again like this?"
"...Yeah, of course."
They smiled at each other, their hips moving slowly and sensuously.
"Haaah... Kotaro, Kotaro...!"
(This is too much happiness...)
Lost in the lover's voice murmuring in his ear, he savored the moment, letting the sensation wash over him.
*****
The next day, at a time that was a little late to call morning:
"Mmm... Huh?"
A pleasant sensation roused me. I remembered spending the night entwined until dawn, showering in a daze and still making love there... By the time we climbed into bed, both of us were nearly drained, and we'd fallen asleep the moment we pulled the quilt over us.
Huh? Where's Misaki-senpai?
I glanced around, but my petite lover was nowhere to be seen. Instead, I felt an odd warmth in my lower abdomen. Then I noticed the quilt bulging oddly.
"Good morning..."
I flipped the quilt back and met the eyes of Misaki, who was sucking on my cock. Her cat-like eyes blinked sleepily before narrowing into a mischievous grin.
"Huh? ...Mmm, good morning. Mmm, chuu, nnnfuuu..."
Misaki barely acknowledged the greeting before taking my cock back into her mouth. She must have been giving me fellatio for quite some time already, as even the pubes were soaked with saliva, and my cock was rock-hard.
Is this heaven...?
Misaki-senpai, cute, beautiful, petite, and adorable, is licking my cock with a dreamy expression. The lingering drowsiness of waking up mingles with the pleasure of the blowjob, making me feel like I'm living out a lewd fantasy.
"Misaki-senpai... I'm gonna come in a second..."
"Mmm? ...Pfft. Oh, really? Then let it all out. Nngh, nngh, nngh, nngh..."
Her hands knead my scrotum gently as she purses her lips into an O shape and slides her thin lips down my shaft. The pleasurable sensation makes the urge to climax bubble up, and my desire bursts in her warm, wet mouth.
"Mmmfuuu... Nngh, nnghk, mmmfuuu...!"
She strokes the base of my cock while swallowing the semen, then swirls her tongue around my glans. When my hips jerk and I groan, Misaki smiles brightly, her eyes narrowing in delight.
"Mmm... Pfft. Haa, I emptied myself completely this morning. Wait here a moment."
Misaki slipped out of bed and headed to the kitchen. I heard the sound of her gargling, and then she returned with a warm, damp towel to gently wipe my cock. After tossing the used towel into the washing machine, she burrowed under the quilt and snuggled tightly against me. She's too efficient and too cute. I want to marry her right now.
"By the way, Kotaro-kun, I have a few questions I'd like to ask you."
"Why are you suddenly acting like a professor? And 'interrogate' is a bit strong..."
"Why did you switch back to formal speech?"
"Ugh..."
Hamster-senpai effortlessly reverted to his usual tone, his pointed remark stinging.
"Come on, why? Spill."
"Ugh... Don't look at me with such innocent eyes... It's too cute..."
"Ugh..."
I let slip my true feelings, and the little senior turned beet red. She's still cute today.
"...I'm sorry. I was able to do it yesterday in the heat of the moment, but now that I'm calm, it still feels... embarrassing."
As I stammered out my explanation, Misaki responded with a cute, "Hmm," and a nod. She's just too adorable, so I absentmindedly stroked her hair, back and forth.
"...Well, I guess there's nothing for it. We'll take it slow, then. Little by little."
"And..." Misaki began, her lips pursing and parting uncertainly.
"Senior Misaki?"
"Umm, so... if you could use casual speech like you did yesterday now and then? The contrast is just so... it makes my heart flutter."
"Huh...?"
My heart softened at these unexpected words.
"So, um... I'd like you to maintain a dual approach for a while, if that's okay with you."
"Why the formalities...?"
With a helpless smile, Misaki's cheeks flushed a soft pink as she groaned adorably, "Ugh..." and pressed her forehead against my chest.
"Um... so... shall we... work together from now on?"
"Ah..."
The whispered words, spoken bashfully, startled me. It was the exact same thing she'd said the morning after we first met. Back then, just like now, I loved Misaki deeply.
But...
Now, more than ever. I knew her so much better now, and my affection for her had grown immeasurably. Even her smile had become even more captivating than before. Above all else, the sunflower-like smile she wore now felt like the most beautiful smile I'd ever seen, surpassing all the tens of thousands of smiles I'd witnessed in my life.
"...Yes, please take care of me. I'll treasure you, Misaki-senpai."
"...Hnn! ...Ngh... Kotaro, Kotaro... Ngh... mmf..."
Misaki's expression softened into a cute, dazed look as she wrapped her arms around Kotaro's back and clung tightly to him.
Hmm, I want to marry her...
Kotaro returned the embrace, holding his little senpai close and soaking up her warmth, completely immersed in the most perfect happiness.
And that's a wrap!
From the moment I conceived this story, I thought, "This is going to be fun..." But actually writing it was even more enjoyable than I imagined! I'm utterly grateful to Kotaro and Misaki for being such wonderful characters.
